The prompting device can be a display screen, and cold water pre-discharge results (such as normal cold water pre-discharge completion, insufficient hot water and the like) are displayed on the display screen to remind a user.

It should be understood that the prompting device may also be a buzzer that can emit a prompt sound or other devices that can remind the user, which is not limited in this application.

In an exemplary embodiment, as shown in fig. 2, the water outlet apparatus further includes: the device comprises a hot water pipe 1, a cold water pipe 2, a cold water pre-discharging pipe 3, a mixing water outlet pipe 4 and a mixing valve 41; the hot water pipe 1 and the cold water pipe 2 are respectively used for conveying hot water and cold water, and the cold water pre-discharging pipe 3 is used for discharging cold water; the input end of the cold water pre-discharging pipe 3 is communicated with the hot water pipe 1; a first water inlet and a second water inlet of the mixing valve 41 are respectively communicated with the hot water pipe 1 and the cold water pipe 2, and a water outlet of the mixing valve 41 is communicated with the mixing water outlet pipe 4; the cold water pre-drain pipe 3 is used as a drain pipe.

Cold water pre-draining pipe 3 is connected on hot water pipe 1, and at the cold water in-process of discharging in advance, what discharge is only the residual cold water in hot water pipe 1, compares and connects in the cold water pre-draining pipe 3 that has now and has reduced the displacement of cold water in advance by a wide margin on mixing the water pipe, has practiced thrift the displacement, has avoided discharging the cold water in cold water pipe 2 as residual water in the lump, has also shortened the required time of cold water pre-draining.

The water outlet device may be a shower, such as: before bathing, the user opens the control valve 31 to pre-discharge cold water, and the user can directly take a bath after the pre-discharge of the cold water is completed, namely, the shower 5 can directly discharge hot water after the pre-discharge of the cold water is completed, so that the user is prevented from waiting for the hot water to become hot for a long time, and the use experience of the user is improved. The water outlet device can also be a related water outlet device of a hand washing sink in a kitchen or a toilet.

In an exemplary embodiment, the water outlet device further includes: the hot water pipe 1, the cold water pipe 2, the mixing water outlet pipe 4 and the mixing valve 41; the hot water pipe 1 and the cold water pipe 2 are respectively arranged for conveying hot water and cold water; a first water inlet and a second water inlet of the mixing valve 41 are respectively communicated with the hot water pipe 1 and the cold water pipe 2, and a water outlet of the mixing valve 41 is communicated with the mixing water outlet pipe 4; the mixing water outlet pipe is used as a water outlet pipe 4.

That is, in addition to the aforementioned installation of the separate cold water pre-discharging pipe 3 for pre-discharging cold water, the cold water pre-discharging can be performed at the mixing water outlet pipe 4 to discharge the residual cold water in the hot water pipe 1, so that the pipeline of the cold water pre-discharging pipe 3 is omitted, and the manufacturing cost of the water outlet device is reduced.

In an exemplary embodiment, the output end of the cold water pre-drain pipe 3 is arranged to communicate with an external drain pipe; or, the control valve 31 is a hot water valve, the output end of the cold water pre-discharging pipe 3 is set to be communicated with the water supply unit of the cold water pipe 2, and a cold water valve is arranged between the output end of the cold water pre-discharging pipe 3 and the water supply unit.

The output end of the cold water pre-discharging pipe 3 is communicated with an external blow-off pipe, in other words, residual cold water discharged by the cold water pre-discharging pipe 3 directly enters the external blow-off pipe, and therefore the cold water pre-discharging pipe is convenient and practical to use, does not need other operations of a user, and works reliably.

The output end of the cold water pre-discharging pipe 3 can also be communicated with a water supply unit (cold water supply unit) of the cold water pipe 2, in other words, residual cold water discharged by the cold water pre-discharging pipe 3 is recycled into the cold water supply unit and is discharged for use through the cold water pipe 2 as cold water, the residual cold water in the hot water pipe 1 is fully recycled, water resources are protected, and the water saving performance of the water outlet device is good.

It should be understood that the output end of the cold water pre-discharging pipe 3 can be freely arranged as the water outlet, in other words, the residual cold water discharged from the cold water pre-discharging pipe 3 can be selectively used by the user, and when the user needs to use the device, a container such as a water bucket is placed at the output end (i.e. the water outlet) of the cold water pre-discharging pipe 3 to collect the residual cold water for use.

In addition, as shown in fig. 2, the water outlet device further includes a mixing valve 41 and a mixing water outlet pipe 4, a first water inlet and a second water inlet of the mixing valve 41 are respectively communicated with the hot water pipe 1 and the cold water pipe 2, and a water outlet of the mixing valve 41 is communicated with the mixing water outlet pipe 4.

The mixing valve 41 is used as a control switch of the mixing water outlet pipe 4, and the mixing valve 41 is opened when a user needs to use hot water, and the mixing valve 41 is closed when the user does not need to use the hot water.

It will be appreciated that during pre-discharge of cold water, i.e. when the control valve 31 on the cold water pre-discharge pipe 3 is open, the mixing valve 41 is in a closed state to prevent cold or hot water from being discharged from the mixing outlet pipe 4 to the user.

The connection point of the cold water pre-discharging pipe 3 and the hot water pipe 1 is arranged on the hot water pipe 1 and close to the mixing valve 41, so that residual cold water in the hot water pipe 1 can be discharged more fully.

The embodiment of the application provides a control method, as shown in fig. 3, the control method is used for the water outlet device, and the control method includes: controlling the control valve 31 to be opened according to the cold water pre-drainage instruction so as to conduct the drainage pipe; determining whether a person enters a set range; based on the entry of a person within the set range, the control valve 31 is controlled to close to shut off the drain. The drain can be a cold water pre-drain pipe 3.

After the control valve 31 is controlled to open according to the cold water pre-discharge instruction, the cold water pre-discharge pipe 3 is conducted to perform the cold water pre-discharge operation.

In the cold water pre-discharging process, whether a person enters the water outlet device or the cold water pre-discharging pipe 3 within a certain range is detected. Whether a person enters the water outlet device or not is transmitted to the controller within the set range, and when the fact that a person approaches the water outlet device is detected, cold water pre-discharging is suspended, so that cold water or hot water discharged from the output end of the cold water pre-discharging pipe 3 serving as a water outlet is prevented from splashing on a user. And when the user leaves the vicinity of the water outlet device, cold water pre-discharging is continuously completed.

In an exemplary embodiment, as shown in fig. 3 and 4, determining whether a person enters a setting range includes: determining whether a person enters a set range or not according to a detection result of the human body sensor; or acquiring detection information of a bathroom device in communication connection with the water outlet device, and determining whether a person enters a set range according to the detection information; or acquiring detection information of terminal equipment in communication connection with the water outlet device, and determining whether people enter a set range according to the detection information.

The manner of acquiring whether a person enters the setting range may be various, such as: arranging a human body sensor to detect whether a person enters the setting range; or judging whether a person enters the set range according to the information of the bathroom device; and then, judging whether a person enters the setting range or not according to the information of the terminal equipment.

In an exemplary embodiment, after controlling the control valve 31 to open according to the cold water pre-discharge command to conduct the cold water pre-discharge pipe 3, the method further comprises: detecting the temperature of water in the cold water pre-discharge pipe 3; and controlling the on-off of the control valve 31 according to the detection result.

According to the control method provided by the embodiment of the application, the cold water pre-discharge is controlled according to the water temperature of the cold water pre-discharge pipe 3, and the discharged residual cold water can be effectively reduced.

In an exemplary embodiment, controlling the on/off of the control valve 31 according to the detection result includes: based on the detection result that the set closing condition is satisfied, the control valve 31 is controlled to close to shut off the cold water pre-discharge pipe 3. Based on the detection result that the set closing condition is not satisfied, the control valve 31 is controlled to maintain the open state.

When the detection result meets the set closing condition, the control valve 31 is closed, the cold water pre-discharging process is finished, so that the automatic control of the cold water pre-discharging process is realized, manual operation closing of a user is not needed, and the use experience of the user is improved.

In an exemplary embodiment, the set-off condition includes at least one of a first off condition, a second off condition, and a third off condition; based on the detection result satisfying the set closing condition, the control valve 31 is controlled to close to shut off the cold water pre-discharge pipe 3, including: based on the detection result that the first closing condition is met, judging that the cold water pre-discharge is normally finished, and controlling the control valve 31 to close; determining that a first cold water pre-discharge abnormal condition occurs based on the detection result satisfying a second closing condition, and controlling the control valve 31 to close; based on the detection result that the third closing condition is satisfied, it is determined that the second cold water preliminary discharge abnormal condition occurs, and the control valve 31 is controlled to close.

After the cold water pre-discharge is finished, various states can exist, such as: 1. the cold water pre-discharge is normally finished, namely the cold water pre-discharge is successfully finished, and the water outlet device can directly discharge hot water with proper temperature; 2. the first cold water pre-discharge abnormal condition is that the hot water in the hot water supply unit of the hot water pipe 1 is insufficient, so that the final outlet water temperature of the mixing outlet pipe 4 cannot reach the set temperature; 3. the second cold water pre-discharge abnormal state, that is, the hot water supply unit of the hot water pipe 1 is damaged and hot water cannot be supplied, so that the mixing outlet pipe 4 cannot supply hot water.

In all three states, the control valve 31 is finally closed to end the cold water pre-discharge process.

In an exemplary embodiment, the water outlet device further includes: a temperature detection device arranged to detect the temperature of the cold water pre-discharge pipe 3; as shown in fig. 4, the first off condition includes: in a first set time t1, the water temperature detected by the temperature detection device is greater than or equal to a first set value s1; the second off condition includes: after a second set time t2, the water temperature detected by the temperature detection device is less than a second set value s2; the third off condition includes: after a third set time t3, the water temperature detected by the temperature detection device is less than a third set value s3; the first set value s1 is greater than the second set value s2, and the second set value s2 is greater than the third set value s3; the first set time t1 is less than the second set time t2, and the second set time t2 is less than the third set time t3.

Within the first set time t1, the water temperature at the temperature detection device is increased from the temperature of the residual cold water to the normal hot water temperature (the first set value s 1), at this time, the cold water pre-discharge is normally finished, and the water outlet device can be normally used subsequently.

After the cold water is pre-discharged for a long time (the second set time t 2), the water temperature at the temperature detection device is still low (smaller than the second set value s 2), at this time, the first cold water is in an abnormal pre-discharge state, and the subsequent water discharge device cannot provide hot water meeting the requirements. In practical application, in this case, after the user starts the cold water pre-discharge and the second set time t2 elapses, the temperature of the pre-discharged water increases, but the temperature of the water required for bathing by the user is still not met, that is, there may be a "hot water in the water heater is insufficient".

After the cold water is pre-discharged for a long time (the third set time t 3), the water temperature at the temperature detection device is still very low (less than the third set value s 3), which is the second cold water pre-discharge abnormal state, and the subsequent water discharge device can not provide hot water meeting the requirement. In practical application, in this case, after the user starts the cold water preliminary discharge, after the third setting t3, the temperature of the water at the preliminary discharge is still the cold water, which is substantially the same as the temperature of the cold water just started to be preliminary discharged, and the temperature of the water required by the user for bathing is far from being satisfied, that is, there may be a situation of "possible damage to the water heater".

The third set time t3 is longer than the second set time t2, and the third set value s3 is shorter than the second set value s2, that is, the third closing condition is longer than the second closing condition, and the temperature of the discharged water is lower, which means that the water outlet device can hardly provide hot water, that is, "the water heater may be damaged", so that the determination condition is more accurate, and the possibility of false alarm is reduced.

It should be understood that the contents of the first, second and third closing conditions are only exemplarily explained here, and the first, second and third closing conditions may also be other contents, such as: the second off condition may be: after the first set time t1, the water temperature of the temperature detection device is smaller than a first set value s1, and water is contained in the hot water pipe 1; the conditions under the setting adopt parameters in the first closing condition, and the judgment condition is simple, namely after the first set time t1, if the water temperature reaches the water temperature required by bathing (namely the water temperature is more than or equal to a first set value s 1), normal cold water pre-discharge is finished, and if the water temperature does not reach the water temperature required by bathing (namely the water temperature is less than the first set value s 1), the condition is 'hot water shortage'. The third off condition may be: after the first set time t1, the water temperature of the temperature detection device is smaller than a first set value s1, and no water exists in the hot water pipe 1; the conditions under the setting adopt parameters in the first closing condition, and the judgment condition is simple, namely, after the first set time t1, if the water temperature does not reach the water temperature required by bathing (namely the water temperature is less than the first set value s 1) and no water exists in the hot water pipe 1, the condition is that the water heater is possibly damaged. A flow meter may be correspondingly arranged in the hot water pipe 1.

In an exemplary embodiment, as shown in fig. 4, the control method further includes: and sending corresponding prompt information according to the judged cold water pre-discharge result.

After the three cold water pre-discharge states are in the above three states, prompt information is sent according to the cold water pre-discharge result, so that a user can know the cold water pre-discharge result. Such as: prompt messages such as 'cold water pre-discharge is completed', 'hot water is insufficient' or 'the water heater is damaged' are displayed on the display screen.

Further, the control method further includes: the control valve 31 is controlled to open according to the cold water pre-discharge instruction so as to conduct the cold water pre-discharge pipe 3.

After the user sends an instruction, the control valve 31 is opened, the cold water pre-discharging pipe 3 is opened to pre-discharge cold water, and the automation degree of the pre-discharging of the cold water is improved.

The cold water pre-discharge instruction is an instruction sent by the remote controller 5 or the terminal equipment; or the cold water pre-discharge instruction is an instruction input by a user through an interactive interface.

The user can send out a cold water pre-discharge instruction through the remote controller 5 or the mobile phone, and the controller receives the instruction and then controls the control valve 31 to be opened so as to pre-discharge the cold water.
