Description

{Cook top for cooking vessel}

The present invention relates to a heating device for a food processor having improved thermal efficiency so as to reduce power consumption.

In general, the electric cooktop is an eco-friendly, low-carbon, low-emission cooking utensil, safe and hygienic, has no harmful gas or soot, does not emit oxygen deficiency or carbon monoxide and can always be cooked in a clean and pleasant environment, The time to reach maximum firepower is short due to the use of new materials of heat source and it is recognized as an energy saving product because it maintains a constant temperature by using temperature sensor.

Such an electric cooktop is composed of a housing forming an outer appearance, a heater part fixed to the housing and radiating heat at a high temperature, and a heating part provided on the upper side of the housing to place the food cooker therein. Accordingly, when power is applied to the heater unit, heat is discharged from the heater unit, the food cooker is heated and the food is cooked.

On the other hand, conventionally, the heater part is formed of a hot wire such as a nickel chromium wire, and the heating part is heated by the convective heat conduction method. Therefore, there is a problem that the heat transfer efficiency due to the convective heat conduction is very low, the heating of the heating plate is delayed, and the electric power is consumed.

In addition, since heat is built in the inside of the heating unit, heat is not uniformly transferred to the whole of the heating unit, and a space for placing a separate heat ray therein is required, thereby increasing the size of the electric cooktop.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a heating apparatus for a food preparation machine according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. Here, the same reference numerals are used for the same components, and a detailed description of known functions and configurations that may unnecessarily obscure the gist of the present invention will be omitted. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art. Accordingly, the shapes and sizes of the elements in the drawings and the like can be exaggerated for clarity.

FIG. 1 is a view showing a heating apparatus for a food tiller according to an embodiment of the present invention, and FIG. 2 is a side view of the heating apparatus for a food tiller shown in FIG.

1 and 2, a heating apparatus 100 for a food preparation machine includes a housing 110, a heating unit 120, a heater unit 130, a heat insulating unit 140, a sensor unit 150, and a control unit 160.

The housing 110 may have a receiving space formed therein and an upper portion opened. More specifically, the housing 110 may be formed of a square frame having an opening at the top, and may be coated with a material having an insulating function inside for the sake of safety.

The heating unit 120 may be mounted on the upper end of the housing 110. More specifically, the heating unit 120 may be formed in a plate shape covering the opened surface of the housing 110, and may be formed of a ceramic glass having good heat resistance and durability.

The heater unit 130 may be disposed on the bottom surface of the heating unit 120. For example, the surface heating resistance paste bonding layer may be formed on the bottom surface of the heating unit 120, and then the heater unit 130 may be mounted on the bottom surface of the heating unit 120. As the heater 130 is directly mounted on the bottom of the heating unit 120, the heat transfer rate is increased, and the heat energy generated in the heater 130 can be more efficiently transmitted to the heating unit 120.

Meanwhile, the heater unit 130 may be formed of a planar heating element having a metallic resistance heating body printed on the lower surface of the heating unit 120 by silk screen printing. Here, the area heating element rapidly increases in temperature when a current is applied, and its structure and principle are already known and will be omitted.

The heat insulating part 140 is provided to prevent the heat source generated from the heater part 130 from flowing out to the outside and may be formed in a shape that is disposed in the housing space of the housing 110 and surrounds the lower part of the heater part 130 have. At this time, the heat insulating part 140 may be formed of a metal material so as not to be damaged by the heat source of the heater part 130, and may be coated with a material having an insulating function inside for safety.

The sensor unit 150 is disposed between the housing 110 and the heat insulating unit 140 to measure the temperature of the heater unit 130. At this time, the sensor unit 150 may be a light sensor or a thermocouple sensor. In order to allow the sensor unit 150 to measure the temperature of the heater unit 130, a hole may be formed in a surface of the heat insulating unit 140 facing the sensor unit 150.

That is, when the sensor unit 150 is disposed too close to the heater unit 130, the sensor unit 150 may be deformed and damaged by the heat generated from the heater unit 130. Therefore, a hole is formed in the heat insulating unit 140 The sensor unit 150 is positioned outside the hole.

Meanwhile, when the sensor unit 150 is made of a non-contact type optical sensor, the hole can be closed using a quartz material blocking member so that the optical sensor is not affected by the heat source in the housing 110. If the sensor unit 150 is made of a contact type thermocouple sensor, thermal deformation can be prevented by covering the portion contacting with the heater unit 130 using an insulating tape such as Teflon wire.

The control unit 160 controls whether or not the power supplied to the heater unit 130 is supplied according to the temperature of the heater unit 130 measured by the sensor unit 150. That is, when the temperature of the heater unit 130 is higher or lower than a preset temperature, the controller 160 controls the temperature of the heater unit 130 by shutting off or connecting the power to the heater unit 130 .

Meanwhile, a sealing member 170 may be provided on the upper side of the heat insulating portion 140. Therefore, the space between the heat insulating part 140 and the heating part 120 is sealed, and the heat source generated from the heater part 130 is not leaked to the outside, so that the heat loss can be reduced. Since the heat insulating part 140 and the heating part 120 are not in direct contact with each other, it is possible to prevent the heat insulating part 140 and the heating part 120 from being damaged or damaged.

According to another aspect of the present invention, the heat insulating portion 140 may be coated with a reflector for reflecting the heat source, which is transmitted downward from the heater portion 130, to the upper side on a surface facing the heater portion 130. At this time, it is preferable that the reflection material is made of a material such as aluminum or silver having high reflectance, but it may be changed according to the need of the user.

As the reflection is applied to the upper part of the heat insulating part 140, the radiant heat of the heater part 130 is transmitted to the air layer in the heat insulating part 140 and the heater part 130 through the reflection. Accordingly, not only the thermal efficiency in the housing 110 can be increased, but also the thermal shock applied to the housing 110 can be minimized by blocking radiation heat from being transmitted to the heat insulating part 140.

As described above, since the heater unit 130 is directly mounted on the bottom surface of the heating unit 120, the heating device 100 for the food preparation unit has a high heat transfer rate, so that heat energy generated in the heater unit 130 is heated So that it can be transmitted more efficiently.

The heat source 140 generated by the heater 130 can be prevented from flowing out to the outside by inserting the heat insulating part 140 formed to cover the lower part of the heater part 130 on the bottom surface of the heating part 120.

In addition, by applying a reflection material to the upper part of the heat insulating part 140 and moving the radiation heat generated from the heater part 130 upward, the thermal efficiency in the housing 110 is increased, and power consumption can be reduced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation and that those skilled in the art will recognize that various modifications and equivalent arrangements may be made therein. It will be possible. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
