Technical Field

The application relates to the technical field of household appliances, in particular to a control method and device of a cooking appliance, electronic equipment and a storage medium.

Background

With the deep application of automation control technology to household appliances, many household appliances can already realize automated work.

For example, in cooking appliances, microwave ovens, electric steamers and other cooking appliances can realize automatic cooking. Specifically, the cooking appliance may detect characteristics of the food material, determine cooking parameters of the food material through the detected characteristics, and automatically cook the food material according to the cooking parameters.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Referring to fig. 1, an embodiment of the present application provides a control method for a cooking appliance, where the control method for the cooking appliance may be executed by the cooking appliance itself or by a cloud control platform, where the cloud control platform may be deployed on an electronic device, such as a terminal or a server. In order to more fully describe the present embodiment, the embodiment is described with an implementation example of the cloud control platform.

Specifically, the flow of the control method of the cooking appliance may include:

step S100: the cloud control platform acquires the cooking time of the food material in the cooking appliance and acquires the current state parameter matched with the cooking time, wherein the current state parameter is used for representing the state of the food material after the cooking time.

Step S200: and the cloud control platform determines working parameters matched with the current state parameters of the cooking appliance.

Step S300: and the cloud control platform controls the cooking appliance to operate according to the working parameters.

The above flow will be described in detail with reference to the application scenario.

In this embodiment, the cooking appliance may be an appliance such as a microwave oven, an electric steamer, etc., and a series of sensors may be disposed on an inner cavity of the cooking appliance for placing food materials, so as to collect various current state parameters of the food materials.

For example, can set up high temperature resistant temperature sensor, humidity transducer, oxygen content sensor and weighing transducer on the chassis of inside cavity, during the interior cavity was placed to the edible material, edible material was located the chassis of inside cavity and contacted with temperature sensor, humidity transducer and weighing transducer. Like this, cooking utensil alright with can gather respectively through temperature sensor, humidity transducer and weight sensor and eat present temperature, humidity and weight of material to and still through oxygen sensor monitoring, gather the oxygen content in cooking utensil's the inside cavity's the air.

In addition, the top of inside cavity can high temperature resistance image sensor, and when eating the material and placing inside cavity, the image sensor at top alright with regard to eating the material and shoot. The cooking utensil sends the picture of shooing to high in the clouds control platform, and high in the clouds control platform is through handling the picture, alright in order to determine the current colour of edible material. Or, the cooking appliance can also automatically process the picture to obtain the current color of the food material, and then send the current color to the cloud control platform.

In this embodiment, the cloud control platform can dock a plurality of cooking utensils, in other words, the cloud control platform controls each cooking utensil in a plurality of cooking utensils to carry out automatic culinary art. The embodiment describes the scheme by taking the cloud control platform to control a certain cooking appliance to perform automatic cooking as an example, so as to facilitate understanding.

In this embodiment, starting from the start of the cooking appliance, the cooking appliance can periodically acquire various current state parameters of the food materials in the cooking appliance, and send the current working mode of the cooking appliance and the various current state parameters of the food materials to the cloud control platform until the cooking of the food materials is finished.

Assume that the cooking appliance is an oven and the food material is chicken legs. The user puts the chicken leg into the baking cavity of the oven, selects the baking mode on the display interface of the oven display panel to bake the meat, and finally starts the oven to bake. When the oven is started, the oven acquires the current temperature, humidity, weight and oxygen content in the air of the chicken leg through various sensors, and takes a picture of the chicken leg. Therefore, the oven can acquire the current temperature, humidity, weight, picture and oxygen content in the air of the chicken leg, and the baking mode is meat baking and sending the meat baking to the cloud control platform. After the oven is started, the oven can periodically acquire the current temperature, humidity, weight and oxygen content in the air of the chicken leg through each sensor every other period, such as every 1 minute or 30 seconds, take pictures of the chicken leg, and continuously send the pictures to the cloud control platform. For the cloud control platform, except that the meat is baked in the baking mode received by the oven, in each period after the oven is started and started, the cloud control platform receives the current temperature, humidity, weight, picture and oxygen content in the air of the chicken leg sent by the oven.

In this embodiment, the parameter types reflecting the current states of the food materials are different under different cooking time lengths. For example, the temperature, color, humidity, and oxygen content in the air of the food material do not change immediately after the food material starts to cook, and therefore the initial state of the food material can be reflected by the weight. After cooking for a period of time, the temperature, humidity, color, weight and oxygen content in the air of the food material change, so that the current state of the food material can be reflected by at least one of the temperature, humidity, color, weight and oxygen content in the air of the food material. Therefore, according to the difference of the cooking time, the cloud control platform can select the current state parameter matched with the cooking time of the food material from various current state parameters of the food material sent by the cooking appliance, so that the selected current state parameter can accurately represent the current state of the food material after the cooking time.

For example, when the cloud control platform receives various current state parameters of the food material sent by the cooking appliance for the first time, the cloud control platform may record a time when the various current state parameters of the food material are received, where the time is a time when the cooking appliance is started. The cloud control platform receives various current state parameters of the food material sent by the cooking appliance every time, and correspondingly records the time when the various current state parameters of the food material are received every time.

Based on the mode, when the cloud control platform receives various current state parameters of the food material for the first time, the cooking appliance is just started at the moment, so that the cloud control platform can determine that the cooking time of the food material is zero.

When the cloud control platform continues to receive the current various state parameters of the food material subsequently, the cloud control platform can determine the time length from the starting of the cooking appliance to the current reception of the current various state parameters of the food material, wherein the time length is the time length of the cooked food material.

Of course, the cloud control platform receives various current state parameters of the food material every time, and the cooked time length of the food material is correspondingly updated through calculation.

In this embodiment, according to the determined cooked time, the cloud control platform determines a current state parameter matched with the cooked time from the current various state parameters of the food material.

For example, the cloud control platform presets thresholds of the duration of the cooking appliance in various working modes, and then based on the current working mode of the cooking appliance sent by the cooking appliance, the cloud control platform may determine a corresponding threshold in the current working mode of the cooking appliance, for example, the corresponding threshold includes a first threshold and a second threshold, and the first threshold is smaller than the second threshold.

It should be noted that the threshold values corresponding to different operation modes are different. For example, in the meat-roasting mode, the first threshold may be 10 minutes, and the second threshold may be 30 minutes; in another example of the operation mode for potato baking, the first threshold value may be 3 minutes and the second threshold value may be 10 minutes.

The cloud control platform also presets which current state parameter corresponds to each small relation between the cooked time length and the threshold value in each working mode. After the cloud control platform determines the size relationship between the cooked time and the threshold, the current state parameters corresponding to the size relationship can be determined according to the size relationship, and then the corresponding current state parameters are selected from the current various state parameters.

For example, when the cloud control platform determines that the cooked time period is equal to zero, it is obvious that the cooked time period is also less than the first threshold. And according to the fact that the cooked time length is equal to zero and smaller than a first threshold value, the cloud control platform determines that the current state parameter corresponding to the cooked time length is weight. Therefore, the cloud control platform can select the temperature from the current temperature, humidity, picture, weight and oxygen content in the air of the food material, so as to use the current weight of the food material for subsequent calculation. In other words, the initial state of the food material needs to be reflected by the weight immediately after the food material starts to cook.

When the cloud control platform determines that the cooked time length is greater than zero and less than a first threshold value, the cloud control platform determines that the current state parameter corresponding to the cooked time length is the temperature according to the fact that the cooked time length is greater than zero and less than the first threshold value. Therefore, the cloud control platform can select the temperature from the current temperature, humidity, picture, weight and oxygen content in the air of the food material, so as to use the current temperature of the food material for subsequent calculation. In other words, after the food starts to cook for a while, the temperature of the food changes, but the color, humidity, weight and oxygen content in the air of the food do not change much, so that the current state of the food can be reflected by the temperature.

When the cloud control platform determines that the cooked time length is greater than or equal to a first threshold value and smaller than a second threshold value, the cloud control platform determines that the current state parameters corresponding to the cooked time length are temperature and color according to the fact that the cooked time length is greater than or equal to the first threshold value and smaller than the second threshold value. Therefore, the cloud control platform can select the temperature and the picture from the current temperature, the current humidity, the current picture, the current weight and the current oxygen content of the food material, and determine the current color of the food material by processing the picture. In other words, after the food material is continuously cooked for a period of time, the temperature of the food material is continuously changed, and the color of the food material is also changed, but the humidity, the weight and the oxygen content in the air of the food material are not greatly changed, so that the current state of the food material can be reflected by the temperature and the color.

When the cloud control platform determines that the cooked time is greater than or equal to a second threshold, according to the cooked time, the current state parameters corresponding to the cooked time are temperature, color, humidity, weight and oxygen content in the air. Therefore, the cloud control platform can select the current temperature, humidity, picture, weight and oxygen content in the air of the food material, and determine the current color of the food material by processing the picture. In other words, after the food material is cooked for the last period of time, the temperature and the color of the food material continue to change, and meanwhile, the humidity, the weight and the oxygen content in the air of the food material all change, so that the current state of the food material can be reflected by the temperature, the humidity, the color, the weight and the oxygen content in the air.

The level of the oxygen content reflects the difference in the degree of maturity of the food material, and reflects the difference between the inherent content of the food material and other food materials. For example, in the case of two different types of chicken legs with the same weight and temperature, the two types of chicken legs have different oxygen contents during cooking due to the different qualities of the two types of chicken legs. Therefore, the respective baking time of the two chicken legs can be determined by analyzing the oxygen content in the cooking process, so that better cooking effect is realized.

In this embodiment, as an exemplary manner of processing the picture of the food material to obtain the color of the food material, the cloud control platform may perform gray processing on the picture of the food material to obtain a gray image. The cloud control platform analyzes the gray value of each pixel point in the gray image based on an edge detection method, so that the pixel points at the edge of the food material can be determined from the gray image, and the occupied area of the food material in the gray image is determined. And finally, the cloud control platform calculates the mean value or the variance of the pixel points in the occupied area, and the mean value or the variance of the pixel points in the occupied area can represent the color of the food material.

Continuing with the previous assumptions, at oven start-up, the current temperature of the chicken leg collected by the oven was 25 ℃, humidity 80%, weight 1kg, and oxygen content in air 23%. The cloud control platform may select a weight of 1kg from 25 ℃, 80% humidity, 1kg weight and 23% oxygen for subsequent processing.

After the oven was started for 2 minutes, the current temperature of the chicken leg collected by the oven was 110 ℃, the humidity was 80%, the weight was 1kg, and the oxygen content was 23%. The cloud control platform may select a temperature of 110 ℃ from a temperature of 110 ℃, a humidity of 80%, a weight of 1kg, and an oxygen content of 23% for subsequent processing.

After the oven was started for 18 minutes, the current temperature of the chicken leg collected by the oven was 320 ℃, the humidity was 80%, the weight was 1kg, and the oxygen content was 23%. The cloud control platform may select a temperature of 320 ℃ from a temperature of 320 ℃, a humidity of 80%, a weight of 1kg, and an oxygen content of 24% for subsequent processing. And the cloud control platform is also used for processing the pictures of the chicken leg acquired when the oven is started to work for 18 minutes so as to obtain the average value of pixel points of the area occupied by the chicken leg as 0.77, and the average value of 0.77 is also used for subsequent processing.

After the oven was started for 30 minutes, the current temperature of the chicken leg collected by the oven was 480 ℃, the humidity was 64%, the weight was 0.78kg, and the oxygen content was 32%. The cloud control platform may use 480 deg.c, 64% humidity, 0.78kg weight, and 32% oxygen for subsequent processing. And the cloud control platform is also used for collecting the pictures of the chicken leg when the oven is started to work for 30 minutes to process so as to obtain the average value of pixel points of the area occupied by the chicken leg as 0.81, and the average value of 0.81 is also used for subsequent processing. It can be understood that the average value of the pixel point is 0.81 and is larger than the average value of the pixel point is 0.77, which indicates that the color of the chicken leg is darker and the chicken leg is close to being cooked quickly.

Various state parameters of the cooking appliance in each working mode are preset in the cloud control platform, and working parameters of the cooking appliance corresponding to each state parameter are also preset. After the current state parameters are selected, the cloud control platform can match the current state parameters with each state parameter of the cooking utensil in the current working mode. Or the cloud control platform can also synthesize the current state parameters and the historical state parameters of the food material to obtain a state mean value, and then match the state mean value with each state parameter of the cooking appliance in the current working mode.

Through matching, the electronic device can judge whether the preset various state parameters have the state parameters same as the current state parameters or judge whether the preset various state parameters have the state parameters same as the state mean value.

If yes, the cloud control platform determines the working parameters corresponding to the same state parameters.

If not, the cloud control platform creates working parameters matched with the current state parameters based on the various working parameters, the various state parameters and the current state parameters; or based on various working parameters, various state parameters and the state mean value, the working parameters matched with the state mean value are created.

It should be noted that the operating parameters are different according to the type of the cooking appliance.

If the cooking appliance is an oven, determining the working parameters corresponding to the same state parameters from the preset working parameters, namely determining the baking time length and the baking temperature corresponding to the same state parameters from the preset baking time lengths and the preset baking temperatures of the oven.

If the cooking appliance is a microwave oven, determining the working parameters corresponding to the same state parameters from the preset various working parameters, namely determining the microwave time length and the microwave power corresponding to the same state parameters from various microwave time lengths and various microwave powers preset by the microwave oven.

If the cooking appliance is an electric steam box, determining the working parameters corresponding to the same state parameters from the preset various working parameters, namely determining the electric steam time and the electric steam temperature corresponding to the same state parameters from various preset electric steam time and various preset electric steam temperatures of the electric steam box.

The following will be described in detail with respect to the above two cases of determining the current state parameter and determining the state mean value:

as a way of judging the current state parameter, the cloud control platform may be correspondingly matched according to the type of the parameter in the current state parameter.

For example, the current state parameter only includes the current weight of the food material, and the cloud control platform may match the current weight with each state parameter of the cooking appliance in the current operating mode, and each state parameter involved in the matching only includes the weight. By matching, if there is the same weight as the current weight. And the cloud control platform can determine working parameters corresponding to the same weight according to the same weight.

Continuing with the above assumption, if the cloud control platform selects that the weight of the chicken leg is 1kg for subsequent processing, the cloud control platform selects whether the weight is the same as 1kg from the preset weights. If yes, the cloud control platform determines the working parameter corresponding to the weight of 1kg from the preset various working parameters, for example, the baking time may be 40 minutes and the baking temperature may be 400 ℃.

For example, the current state parameter only includes the current temperature of the food material, so the cloud control platform can match the current temperature with each state parameter of the cooking appliance in the current working mode, and each state parameter participating in matching only includes the temperature. By matching, if there is a temperature equal to the current temperature. And the cloud control platform can determine working parameters corresponding to the same temperature according to the same temperature.

Continuing with the above assumption, if the cloud control platform selects the chicken leg temperature of 110 ℃ for subsequent processing, the cloud control platform selects whether the temperature is the same as 110 ℃ from various preset temperatures. If yes, the cloud control platform determines the working parameter corresponding to the temperature of 110 ℃ from various preset working parameters, for example, the baking time may be 36 minutes and the baking temperature may be 400 ℃.

For example, the current state parameters only include the current temperature and color of the food material, so that the cloud control platform can match the current temperature and color with each state parameter of the cooking appliance in the current working mode, and each state parameter participating in matching only includes the temperature and the color. By matching, if there is a state parameter identical to the current state parameter, that is, the temperature in the identical state parameter is identical to the current temperature, the color in the identical state parameter is identical to the current color. And the cloud control platform can determine working parameters corresponding to the same temperature and color according to the same temperature and color.

Continuing with the above assumption, the cloud control platform selects the chicken leg temperature of 320 ℃ and the color of 0.77 for subsequent processing, and then selects whether the temperature is the same as 320 ℃ from various preset temperatures and whether the color is the same as 0.77 from various preset colors. If so, the cloud control platform determines the working parameters corresponding to the temperature of 320 ℃ and the color of 0.77 from the preset working parameters, for example, the baking time may be 20 minutes and the baking temperature may be 540 ℃.

For example, the current state parameters include the current temperature, color, humidity, weight, and oxygen content in the air of the food material, so that the cloud control platform can match the current temperature, color, humidity, weight, and oxygen content in the air with each state parameter of the cooking appliance in the current operating mode, and each state parameter participating in matching also includes the temperature, color, humidity, weight, and oxygen content in the air. By matching, if there is a same state parameter as the current state parameter, i.e. the temperature in the same state parameter is the same as the current temperature, the color in the same state parameter is the same as the current color, the humidity in the same state parameter is the same as the current humidity, the weight in the same state parameter is the same as the current weight, and the oxygen content in the same state parameter is the same as the current oxygen content. The cloud control platform can determine working parameters corresponding to the same temperature, color, humidity, weight and oxygen content according to the same temperature, color, humidity, weight and oxygen content.

Continuing with the above assumption, the cloud control platform selects the chicken leg temperature of 480 ℃, humidity of 64%, weight of 0.78kg, color of 0.81, and oxygen content of 32% for subsequent processing, and then selects whether there is the same temperature as 480 ℃ from various preset temperatures, selects whether there is the same color as 0.81 from various preset colors, selects whether there is the same weight as 0.78kg from various preset weights, selects whether there is the same humidity as 64% from various preset humidities, and selects whether there is the same oxygen content as 32% from various preset oxygen contents as 32%. If yes, the cloud control platform determines the working parameters corresponding to the temperature of 480 ℃, the humidity of 64%, the weight of 0.78kg, the color of 0.81 and the oxygen content of 32% from the preset working parameters, such as the baking time of 12 minutes and the baking temperature of 480 ℃.

In this embodiment, if the cloud control platform determines that there is no state parameter that is the same as the current state parameter in the preset various state parameters. The cloud control platform can create working parameters matched with the current state parameters based on various preset working parameters, various state parameters and the current state parameters of the cooking appliance in the current working mode.

For example, the cloud control platform may determine a state parameter closest to a current state parameter from various preset state parameters in a current working mode of the cooking appliance. The cloud control platform can adjust working parameters corresponding to the closest state parameters in various preset working parameters of the cooking appliance in the current working mode according to the difference between the closest state parameters and the current state parameters, so that the working parameters matched with the current state parameters are obtained. Before adjusting the working parameter corresponding to the closest state parameter, the working parameter corresponding to the closest state parameter may be copied to ensure that after adjustment, a copy of the working parameter corresponding to the closest state parameter is left.

Specifically, under the condition that the current state parameters only include one parameter, the cloud control platform determines the closest state parameter according to the difference between the parameter and the corresponding various state parameters.

For example, if the current state parameters only include the current weight of the food material, the cloud control platform may determine a difference between each weight and the current weight from various state parameters of the cooking appliance in the current operating mode and only including the weight, and select the smallest weight difference, where the weight corresponding to the smallest weight difference is the weight closest to the current weight. And finally, the cloud control platform adjusts the working parameters corresponding to the closest weight according to the minimum weight difference, so that the working parameters matched with the current weight are obtained.

Continuing the above assumption, if there is no weight equal to 1kg among the preset weights, and 1.2kg, which is the closest weight to 1kg, among the preset weights differs from 1kg by +0.2 kg. Then, the cloud control platform adjusts the working parameter corresponding to the closest weight of 1.2kg according to the difference of +0.2 kg. For example, if the closest operating parameters for a weight of 1.2kg are a baking time of 40 minutes and a baking temperature of 400 ℃, then the baking time may be adjusted to 32 minutes and a baking temperature of 360 ℃.

For example, the current state parameters only include the current temperature of the food material, the cloud control platform may determine the difference between each temperature and the current temperature from various state parameters of the cooking appliance in the current operating mode and only including the temperature, and select the minimum temperature difference, where the temperature corresponding to the minimum temperature difference is the temperature closest to the current temperature. And finally, the cloud control platform adjusts the working parameters corresponding to the closest temperature according to the minimum temperature difference, so that the working parameters matched with the current temperature are obtained.

Continuing the above assumptions, if there is no temperature in the predetermined weights that is the same as 110 ℃, and the temperature 108 ℃ in the predetermined weights that is closest to 110 ℃ is different from it by-2 ℃. Then, the cloud control platform adjusts the working parameter corresponding to the closest temperature of 108 ℃ according to the phase difference of-2 ℃. For example, the closest temperature of 108 ℃ corresponds to an operating parameter of 36 minutes and a baking temperature of 400 ℃, and then the baking time duration can be adjusted to 38 minutes and the baking temperature of 410 ℃.

Under the condition that the current state parameters comprise at least two of current temperature, color, humidity and weight, aiming at each state parameter, the cloud control platform can determine the difference between each parameter in the current state parameters and a corresponding parameter in the state parameters, and then carry out weighted summation on the differences of the parameters according to the preset weight of each parameter, so that the difference between the current state parameters and the closest state parameters is obtained.

For example, the current state parameters include the current temperature and color of the food material, and the cloud control platform may calculate the difference between each state parameter and the current state parameter from various state parameters that only include the temperature and the color and are currently in the operating mode of the cooking appliance.

For one of the state parameters, the cloud control platform can calculate the temperature difference between the temperature in the state parameter and the current temperature, and calculate the temperature difference between the color in the state parameter and the current color. Since the evaluation magnitudes of temperature and color are generally different, the magnitude of temperature difference is generally in the single digit, while the magnitude of color difference is generally in the decimal place. The difference in temperature and color can be unified to the same order by weighting. For example, the temperature difference is set to be 0.1 in weight and the color difference to be 0.9 in weight, and the product of the temperature difference multiplied by 0.1 and the product of the color difference multiplied by 0.9 are added to obtain the difference of the state parameter and the current state parameter.

And calculating the difference between each state parameter and the current state parameter, wherein the cloud control platform can select the minimum difference, and the state parameter corresponding to the minimum difference is the state parameter closest to the current state parameter. And the cloud control platform adjusts the working parameters corresponding to the closest state parameters according to the minimum difference, so that the working parameters matched with the current state parameters are obtained.

Continuing with the above assumption, if none of the preset state parameters includes the same temperature and color as the temperature of 320 ℃ and the color of 0.77, and the close set of state parameters includes the same temperature of 325 ℃ and the color of 0.74, the cloud control platform determines that the minimum difference corresponding to the close set of state parameters is 5 × 0.1-0.3 × 0.9 — 0.23 according to the preset weight of the temperature difference of 0.1 and the weight of the color difference of 0.9. If the close set of state parameters correspond to the working parameters of 20 minutes of baking time and 540 ℃. Then, according to the minimum difference of 0.23, it is possible to adjust it to a baking time of 24 minutes and a baking temperature of 540 ℃ (540 ℃ is the maximum temperature, so that the rise cannot be adjusted any more).

For another example, the current state parameters include the current temperature, color, humidity, weight and oxygen content in the air of the food material, and the cloud control platform may calculate the difference between each state parameter and the current state parameter from various state parameters including the temperature, color, humidity, weight and oxygen content in the air in the current operating mode of the cooking appliance.

And for one of the state parameters, the cloud control platform can calculate the temperature difference between the temperature in the state parameter and the current temperature, calculate the temperature difference between the color in the state parameter and the current color, calculate the humidity difference between the humidity in the state parameter and the current humidity, and calculate the weight difference between the weight in the state parameter and the current weight. Since the evaluation magnitudes of temperature, color, humidity and weight are also generally different, the magnitude of temperature difference is generally in single digits, the magnitude of color difference is generally in one decimal place, the magnitude of weight difference is also generally in one decimal place, the magnitude of humidity difference is generally in two decimal places, and the magnitude of oxygen content difference is also generally in two decimal places. Therefore, the difference between the temperature and the color can be unified to the same order by weighting. For example, a weight of the temperature difference is set to 0.01, a weight of the color difference is set to 0.1, a weight of the weight difference is set to 0.1, and a weight of the humidity difference is set to 0.4, and a weight of the oxygen content difference is set to 0.39. The difference between the state parameter and the current state parameter is obtained by adding the product of the temperature difference multiplied by 0.01, the product of the color difference multiplied by 0.1, the product of the weight difference multiplied by 0.1, and the product of the humidity difference multiplied by 0.79, and then multiplying the sum by 10.

Continuing with the above assumption, if none of the preset state parameters includes the same temperature, color, humidity and weight as 480 ℃, 64% humidity, 0.78kg weight, 0.81 color and 32% oxygen content, and the close set of state parameters includes 482 ℃, 68% humidity, 0.79kg weight, 0.81 color and 36% oxygen content, the cloud control platform determines that the minimum difference corresponding to the close set of state parameters is 0.61 (2 × 0.01-0.04 × 0.4-0.04 × 0.39+ 0.1) — based on the weight of the temperature difference being 0.01, the weight of the color difference being 0.1, the weight of the weight difference being 0.1, the weight of the humidity difference being 0.4, and the weight of the oxygen content difference being 0.39. If the close set of state parameters correspond to the working parameters of 12 minutes of baking time and 480 ℃ of baking temperature. Then it can be adjusted to a baking time of 16 minutes and a baking temperature of 540 c, according to the minimum difference of 0.61.

When the operating parameter corresponding to the closest state parameter is adjusted based on the difference, the adjustment width for the operating parameter corresponding to the closest state parameter is larger as the difference is larger, and is smaller as the difference is larger.

As a way of judging the state mean value, the cloud control platform may determine whether the current state parameter has a historical state parameter, and if not, the current state parameter is directly used for matching. If yes, determining the average value of each parameter in the current state parameter and the historical state parameter, and correspondingly matching each parameter. In order to ensure accuracy, the historical state parameter may be a parameter at which the acquired time point is relatively close to the current time, for example, a historical state parameter within 5 minutes from the current time.

For example, when the current state parameter only includes the current weight of the food material, it indicates that the cooking appliance has just been started, and there is no historical weight, so the current weight is directly matched in the manner described above, and thus the description is omitted here.

For another example, the current state parameter only includes the current temperature of the food material, which indicates that the cooking appliance is started, and then the cloud control platform determines whether the historical state parameter only including the temperature is obtained.

If not, the current state parameters are directly used for matching, the principle is the same as that of the previous step, and the description is not repeated here.

If so, determining a temperature average value between the current temperature and the historical temperature, wherein the average value can be determined in a weighted average manner or a direct average manner. Then, the cloud control platform can match the temperature mean value with each state parameter of the cooking appliance in the current working mode, and each state parameter participating in matching only includes the temperature. By matching, if there is a temperature that is the same as the mean temperature. And the cloud control platform can determine working parameters corresponding to the same temperature according to the same temperature.

Continuing with the assumption, the cloud control platform performs weighted average according to that the current temperature of the chicken leg is 110 ℃ and the historical temperatures are 100 ℃ and 90 ℃ respectively to obtain a temperature average value of 104 ℃, and then the cloud control platform selects whether the temperature is the same as 104 ℃ from the preset various temperatures. If yes, the cloud control platform determines the working parameter corresponding to the temperature of 104 ℃ from various preset working parameters, for example, the baking time may be 38 minutes and the baking temperature may be 420 ℃.

For another example, if the current state parameters only include the current temperature and color of the food material, which indicates that the cooking appliance is started, the cloud control platform determines whether the historical state parameters only including the temperature and the color are obtained.

If so, determining a temperature average value between the current temperature and the historical temperature, and determining a historical average value between the current color and the historical color, wherein the average value can be determined in a weighted average manner or a direct average manner. Then, the cloud control platform can match the temperature mean value and the historical mean value with each state parameter of the cooking appliance in the current working mode, and each state parameter participating in matching only comprises the temperature and the color. By matching, if there is a state parameter identical to the current state parameter, the temperature in the identical state parameter is identical to the temperature average value, and the color in the identical state parameter is identical to the color average value. And the cloud control platform can determine working parameters corresponding to the same temperature and color according to the same temperature and color.

Continuing with the above assumption, the cloud control platform performs weighted average on the current temperature of the chicken leg of 320 ℃, and the historical temperatures of 310 ℃ and 300 ℃, and determines that the temperature average is 314 ℃. And the cloud control platform further performs weighted average on the current color of the chicken leg being 0.77 and the historical colors being 0.74 and 0.70, and determines that the color mean value is 0.75. The cloud control platform selects whether the temperature is the same as 314 ℃ from various preset temperatures and selects whether the color is the same as 0.75 from various preset colors. If so, the cloud control platform determines the working parameters corresponding to the temperature of 314 ℃ and the color of 0.75 from the preset working parameters, for example, the baking time may be 24 minutes and the baking temperature may be 540 ℃.

For another example, the current state parameters include the current temperature, color, humidity, and weight of the food material, which indicates that the cooking appliance is started, and then the cloud control platform also determines whether historical state parameters including the temperature, color, humidity, and weight are obtained.

If so, determining a temperature average value between the current temperature and the historical temperature, determining a color average value between the current color and the historical color, determining a temperature average value between the current humidity and the historical humidity, and determining a weight average value between the current weight and the historical weight, wherein the average value can be determined in a weighted average manner or a direct average manner.

Then, the cloud control platform can match the temperature mean value, the color mean value, the humidity mean value and the weight mean value with each state parameter of the cooking appliance in the current working mode, and each state parameter participating in matching also comprises temperature, color, humidity and weight. By matching, if there is a state parameter that is the same as the current state parameter, i.e., the temperature in the same state parameter is the same as the temperature mean, the color in the same state parameter is the same as the color mean, the humidity in the same state parameter is the same as the humidity mean, and the weight in the same state parameter is the same as the weight mean. The cloud control platform can determine working parameters corresponding to the same temperature, color, humidity and weight according to the same temperature, color, humidity and weight.

Continuing with the assumption, the cloud control platform performs weighted average on the current temperature of the chicken leg being 480 ℃ and the historical temperatures being 470 ℃ and 460 ℃ respectively, and determines the temperature average value to be 476 ℃; the cloud control platform carries out weighted average on the current humidity of the chicken leg of 64 percent and the historical humidity of 66 percent and 68 percent respectively to determine that the average humidity value is 65 percent; the cloud control platform carries out weighted average on the current weight of the chicken leg being 0.78kg and the historical weights being 0.80kg and 0.82kg respectively, and the weight average value is determined to be 0.79 kg; the cloud control platform carries out weighted average on the current color of the chicken leg to be 0.81 and the historical colors to be 0.79 and 0.77 respectively, and the average value of the colors is determined to be 0.80; the cloud control platform carries out weighted average on the current oxygen content of 32% in the air and the historical oxygen content of 30% and 28% respectively, and the average value of the oxygen content is determined to be 31%.

Then the cloud control platform selects whether the temperature is the same as 476 ℃ from various preset temperatures, selects whether the color is the same as 0.80 from various preset colors, selects whether the weight is the same as 0.79kg from various preset weights, selects whether the humidity is the same as 65% from various preset humidities, and selects whether the oxygen content is the same as 31% from various preset oxygen contents. If yes, the cloud control platform determines the corresponding operating parameters of 476 ℃, 65% humidity, 0.79kg weight, 0.80 color and 31% oxygen content from the preset operating parameters, such as 13 minutes baking time and 490 ℃ baking temperature.

In this embodiment, if the cloud control platform determines that there is no state parameter that is the same as the state mean value among the preset various state parameters. The cloud control platform can create working parameters matched with the current state mean value based on various preset working parameters, various state parameters and the state mean value in the current working mode of the cooking appliance.

For example, the cloud control platform may determine the state parameter closest to the state average value from various preset state parameters in the current working mode of the cooking appliance. The cloud control platform can adjust working parameters corresponding to the closest state parameters in various preset working parameters under the current working mode of the cooking appliance according to the difference between the closest state parameters and the state mean value, so that the working parameters matched with the state mean value are obtained.

Specifically, under the condition that the state mean value only contains one parameter, the cloud control platform determines the closest state parameter according to the difference between the parameter and the corresponding various state parameters.

For example, the state mean value only includes the food material temperature mean value, the cloud control platform may determine a difference between each temperature and the state mean value from various state parameters of the cooking appliance in the current operating mode and only including the temperature, and select the minimum temperature difference, where the temperature corresponding to the minimum temperature difference is the temperature closest to the current temperature. And finally, the cloud control platform adjusts the working parameters corresponding to the closest temperature according to the minimum temperature difference, so that the working parameters matched with the current temperature are obtained.

And under the condition that the state mean value comprises at least two parameters of the temperature mean value, the color mean value, the humidity mean value and the weight mean value, aiming at each state mean value, the cloud control platform can determine the difference between each mean value in the state mean value and a corresponding mean value in the state mean value, and then, according to the preset weight of each mean value, the differences of the mean values are weighted and summed, so that the difference between the state mean value and the closest state parameter is obtained.

For example, the state mean value only includes the temperature mean value and the color mean value of the food material, and the cloud control platform may calculate the difference between each state parameter and the state mean value from various state parameters that only include the temperature and the color in the current operating mode of the cooking appliance.

And aiming at one of the state parameters, the cloud control platform can calculate the temperature difference between the temperature in the state parameter and the temperature mean value and calculate the temperature difference between the color in the state parameter and the color mean value. Since the evaluation magnitudes of temperature and color are generally different, the magnitude of temperature difference is generally in the single digit, while the magnitude of color difference is generally in the decimal place. The difference in temperature and color can be unified to the same order by weighting. For example, the temperature difference is set to be 0.1 in weight and the color difference to be 0.9 in weight, and the product of the temperature difference multiplied by 0.1 and the product of the color difference multiplied by 0.9 are added to obtain the difference of the state parameter and the state mean.

And calculating the difference between each state parameter and the state mean value, wherein the cloud control platform can select the minimum difference, and the state parameter corresponding to the minimum difference is the state parameter closest to the state mean value. And the cloud control platform adjusts the working parameters corresponding to the closest state parameters according to the minimum difference, so that the working parameters matched with the state mean value are obtained.

For another example, the state mean includes a temperature mean, a humidity mean, a weight mean of the food material, and an oxygen content mean in the air, so that the cloud control platform can calculate a difference between each state parameter and the state mean from various state parameters including temperature, color, humidity, weight, and oxygen content in the current operating mode of the cooking appliance.

And for one of the state parameters, the cloud control platform can calculate the temperature difference between the temperature in the state parameter and the temperature mean value, calculate the temperature difference between the color in the state parameter and the color mean value, calculate the humidity difference between the humidity in the state parameter and the humidity mean value, and calculate the weight difference between the weight in the state parameter and the weight mean value. Since the evaluation magnitudes of temperature, color, humidity and weight are also generally different, the magnitude of the temperature difference is generally in single digits, the magnitude of the color difference is generally in one decimal place, the magnitude of the weight difference is also generally in one decimal place, and the magnitude of the humidity difference is generally in two decimal places. Therefore, the difference between the temperature and the color can be unified to the same order by weighting. For example, a weight of the temperature difference is set to 0.01, a weight of the color difference is set to 0.1, a weight of the weight difference is set to 0.1, and a weight of the humidity difference is set to 0.79. The difference between the state parameter and the state mean is obtained by adding the product of the temperature difference multiplied by 0.01, the product of the color difference multiplied by 0.1, the product of the weight difference multiplied by 0.1, and the product of the humidity difference multiplied by 0.79, and then multiplying the sum by 10.

And calculating the difference between each state parameter and the state mean value, wherein the cloud control platform can select the minimum difference, and the state parameter corresponding to the minimum difference is the state parameter closest to the state mean value. And the cloud control platform adjusts the working parameters corresponding to the closest state parameters according to the minimum difference, so that the working parameters matched with the current state parameters are obtained.

After the cloud control platform determines the working parameters, the cloud control platform issues the working parameters to the cooking utensil, so that the cooking utensil operates according to the working parameters.

In this embodiment, except for the above-mentioned interaction mode, the cloud control platform and the cooking utensil, the user can also upload self-defined working parameters to the cloud control platform through the cooking utensil and store the self-defined working parameters as preset working parameters. In addition, the cloud control platform can issue the configuration file of the latest function to the cooking appliance, the cooking appliance can execute the latest function through the configuration file, and due to the fact that the cooking appliance is provided with the display interface, the function options of the latest function can be displayed on the display interface of the cooking appliance.
