These water supply devices can provide hot water to meet the needs of making hot drinks such as tea and coffee, and at the same time, they can also provide cold water to quench thirst, especially in the hot summer. Therefore, the existence of water supply devices has brought great convenience to our lives and improved the usability and comfort of water.

They usually store hot water and cold water separately and discharge them through corresponding drain outlets when needed by users. Although this operation method can meet the basic cold and hot water needs, it cannot achieve fine control of the temperature of the discharged water. For example, when a user drinks cold water, sometimes they may hope to get water at a temperature slightly lower than room temperature, but the existing water supply devices cannot meet such a need.

[0059] As Figure 2 shown, in one embodiment, a method for controlling the outlet water temperature of a water supply device is provided. This method can be applied to both the terminal and the server. In this embodiment, it is exemplified by being applied to the terminal.

[0060] A method for controlling the outlet water temperature of a water supply device according to the present application. The method is applied to the water supply device waterway. The water supply device waterway includes: a first water pipeline, a second water pipeline, and a third water pipeline. The first water pipeline and the second water pipeline are respectively communicated with the third water pipeline. A first valve is provided on the first water pipeline and / or a second valve is provided on the second water pipeline. The method for controlling the outlet water temperature of this water supply device specifically includes the following steps:

[0061] S1: Obtain the preset outlet water temperature and the outlet water signal set by the user;

[0062] S2: Obtain the first temperature in the first water pipeline and the second temperature in the second water pipeline in response to the water outlet signal;

[0063] S3: Determine the first control parameter of the first valve and / or the second control parameter of the second valve based on the first temperature and the second temperature;

[0064] S4: Control the first valve based on the first control parameter of the first valve and / or control the second valve based on the second control parameter of the second valve, so that the water discharged from the third water pipeline is the preset water outlet temperature.

[0065] As described in step S1 above, obtain the preset water outlet temperature set by the user and the water outlet signal. It should be noted that the preset water outlet temperature can be the temperature preset by the user in advance, or the preset water outlet temperature input together with the water outlet signal. The obtaining method can be that the user inputs through the touch screen, and the current temperature setting and real-time temperature feedback will be displayed on the screen. The user can adjust the temperature by sliding or clicking, or other methods, such as a knob or a button. It can also be connected and input through a mobile phone APP. This application does not limit this.

[0066] As described in step S2 above, obtain the first temperature in the first water pipeline and the second temperature in the second water pipeline in response to the water outlet signal. In response to the user's water outlet signal, collect real-time temperature data from the first water pipeline and the second water pipeline, which is a key input for subsequent valve opening calculation and mixing water control. It is necessary to read the real-time temperature data in the first water pipeline and the second water pipeline to determine the initial temperatures of hot water and cold water. Specifically, the real-time temperature data can be obtained through corresponding temperature sensors. In some embodiments, temperature sensors may not be designed either. For example, based on the functions of the heating unit and the cooling unit, the temperature of the liquid can be controlled at a specified temperature. At this time, it is not necessary to obtain the temperature through a temperature sensor, but directly default the temperature of the liquid in the corresponding water pipeline as the default temperature. However, for more precise control, it is preferred to set corresponding temperature sensors to obtain the temperature, and the temperature sensors should be as close as possible to the outlet position, that is, the position connected to the third water pipeline, to reduce the influence brought by the heat loss of the pipeline. By responding to the water outlet signal, the system can obtain the real-time temperature data in the first water pipeline and the second water pipeline. Combining high-precision temperature sensors and an efficient data acquisition and processing mechanism can provide an accurate and reliable basis for the subsequent calculation of the mixing water ratio.

[0067] As described in step S3 above, the water supply device system needs to calculate and determine the control parameter of the first valve and / or the second control parameter of the second valve according to the first temperature (hot water temperature) and the second temperature (cold water temperature) collected in real time. In some embodiments, only one valve needs to be controlled to achieve the water outlet at the target temperature, that is, to set the control parameter of the first valve or the control parameter of the second valve. That is to say, in some embodiments, only one valve needs to be set, that is, only the first valve or the second valve needs to be set to achieve the technical solution. Preferably, two valves are set, that is, the first valve and the second valve are set at the same time, so that the water outlet at the target temperature can be obtained faster and the user experience can be improved. By adjusting the opening degree of the valve, the temperature of the mixed water outlet reaches the target temperature preset by the user. According to the actual values of the first temperature and the second temperature, the opening degrees of the first valve (controlling the hot water flow) and the second valve (controlling the cold water flow) are adjusted to obtain the preset water outlet temperature.

[0068] Specifically, according to the formula Set the water outlet temperature, where V 1 represents the flow rate of the first water pipeline, which is controlled by the first valve, T 1 represents the first temperature, T mix represents the water outlet temperature, V 2 represents the flow rate of the second water pipeline, which is controlled by the second valve, T 2 represents the second temperature. Therefore, the corresponding V 1 and V 2 can be calculated according to the formula. In some embodiments, there are certain restrictions on the flow rate of the water outlet. Therefore, the optimal solutions of V 1 and V 2 can be further obtained. By analyzing the actual first temperature and second temperature and combining with the preset water outlet temperature set by the user, the water supply device precisely controls the hot water flow rate V 1 and the cold water flow rate V 2 to adjust the valve opening degree, and finally make the temperature of the mixed water reach the target temperature required by the user.

[0069] As described in step S4 above, control the first valve based on the first control parameter of the first valve and / or control the second valve based on the second control parameter of the second valve, so that the water discharged from the third water pipeline is the preset water outlet temperature. The relationship between the valve opening degree and the flow rate is usually linear or nearly linear, and the specific relationship depends on the characteristics of the valve. The relationship between the valve opening degree and the flow rate is usually linear or nearly linear, and the specific relationship depends on the characteristics of the valve. By adjusting the opening degrees of the hot water and cold water valves based on the valve control parameters, the water supply device system can precisely control the water outlet temperature. Combining with the closed-loop control technology, the system can dynamically adjust the parameters during operation to ensure that the water outlet temperature is always stable at the target value set by the user.

[0070] Referring to Figure 7 , in one embodiment, the water supply device waterway further includes a fourth waterway pipe, and a third valve is provided on the fourth waterway pipe. After the step S1 of obtaining the preset outlet water temperature and the outlet water signal set by the user, the following steps are further included:

[0071] S201: In response to the outlet water signal, obtain the first temperature in the first waterway pipe, the second temperature in the second waterway pipe, and the third temperature in the fourth waterway pipe;

[0072] S202: Determine the first control parameter of the first valve and / or the second control parameter of the second valve and the third control parameter of the third valve based on the first temperature, the second temperature, and the third temperature;

[0073] S203: Control the first valve based on the first control parameter of the first valve and / or control the second valve based on the second control parameter of the second valve, and control the third valve based on the third control parameter of the third valve, so that the temperature of the water discharged from the water outlet is the preset outlet water temperature.

[0074] As described in the above steps S201 - S203, a more flexible and efficient outlet water temperature control scheme is provided. The fourth waterway pipe is introduced to provide direct water supply close to the ambient temperature (or unheated or cooled water). The flow of this waterway is controlled by a third valve, which jointly adjusts the mixed outlet water temperature with the first waterway (hot water) and the second waterway (cold water). The ambient water in the fourth waterway can supplement the deficiencies of hot water and cold water, avoiding the limitations of solely relying on the adjustment of the cold and hot waterways. When the target temperature is close to the ambient temperature, there is no need for additional heating or cooling, and the demand can be met directly by supplying water through the fourth waterway. When the temperature fluctuates greatly, adding ambient water can quickly balance the temperature and reduce over - adjustment. In addition, in one embodiment, if the preset temperature set by the user is lower than normal temperature, only normal temperature water and cold water need to be mixed; if the preset temperature set by the user is higher than normal temperature, only normal temperature water and hot water need to be mixed. Of course, if the temperature set by the user is moderate and the temperature of the hot water is relatively high, in order to reach the temperature required by the user as soon as possible, hot water and cold water can be mixed.

[0075] In one embodiment, the water supply device waterway further includes a return pipe and a second water pump. The return pipe is communicated with the third waterway pipe, and the second water pump is connected to the return pipe. Before the step S4 of controlling the first valve based on the first control parameter of the first valve and / or controlling the second valve based on the second control parameter of the second valve so that the water discharged from the third waterway pipe is the preset outlet water temperature, the following steps are further included:

[0076] S301: Determine whether there is liquid in the third water pipeline;

[0077] S302: If there is liquid in the third water pipeline, control the second water pump to extract the liquid existing in the third water pipeline through the return pipeline.

[0078] In one embodiment, refer to Figure 3 , in one embodiment, it further includes a return pipeline 140 and a second water pump 100. The return pipeline 140 is communicated with the third water pipeline 130, and the second water pump 100 is connected to the return pipeline 140 for extracting the liquid in the third water path. The purpose of judging the existence of liquid is to confirm whether there is enough liquid in the third water pipeline for adjustment or supplementation. The system detects whether there is water flow in the water pipe through a liquid level sensor or a pressure sensor. The purpose of extracting the liquid is to pump out the water in the third water path through the second water pump and return it to the water path system through the return pipeline or directly discharge it as waste liquid. This is to avoid the water in the third water pipeline not meeting the user's requirements and discharging it so that the discharged water temperature can meet the user's needs.

[0079] In one embodiment, a temperature detection unit is further provided at the water outlet. After step S4 of controlling the first valve based on the first control parameter of the first valve and / or controlling the second valve based on the second control parameter of the second valve so that the water discharged from the third water pipeline is the preset outlet water temperature, it further includes:

[0080] S501: Detect the target temperature of the water in the third water pipeline according to the temperature detection unit;

[0081] S502: Judge whether the absolute value of the difference between the target temperature and the preset outlet water temperature is greater than a preset value;

[0082] S503: If it is greater than the preset value, adjust the first valve and / or the second valve based on the values of the target temperature and the preset outlet water temperature.

[0083] In one embodiment, refer to Figure 4, in one embodiment, it further includes a temperature detection unit 120. The temperature detection unit 120 is connected to the control unit 70 and the third water pipeline 130, and is used to detect the temperature of the liquid in the third water path. The actual temperature of the water outlet is monitored in real time by using a temperature detection unit (such as a contact or non-contact temperature sensor) installed at the water outlet. The temperature detection unit may include a high-precision thermocouple, a PT100 sensor or other suitable temperature sensors to ensure the accuracy of the read data. The system compares the target temperature (the preset water outlet temperature set by the user) with the detected actual water outlet temperature (the target temperature). If the temperature difference exceeds the preset value, in order to restore the target water temperature, the system will adjust the operating states of the first valve and / or the second valve according to the detected direction and magnitude of the temperature difference. The first water pump may be used to increase or decrease the input intensity of hot water. The second water pump may be used to adjust the flow rate of cold water or other water paths. For example, if the detected temperature is higher than the target temperature, the following operations can be performed: increase the operation of the second water pump to increase the inflow of cold water; reduce the efficiency of the first water pump to reduce the supply of hot water. If the detected temperature is lower than the target temperature, the opposite operations are taken. Through such a dynamic feedback and automatic adjustment mechanism, the system can quickly return the water outlet temperature to the set value, better cope with the system parameter drift caused by environmental changes or the aging of the water supply device, and ensure a constant water temperature during long-term stable operation.

[0084] Before the step S1 of obtaining the preset water outlet temperature and the water outlet signal set by the user, it further includes:

[0085] S001: Obtain the preset water outlet temperature required by the user in each time period;

[0086] S002: Set the first water temperature parameter in the first water pipeline and the second water temperature parameter in the second water pipeline according to the preset water outlet temperature required in each time period;

[0087] S003: Obtain the current time, and obtain the first water temperature parameter and the second water temperature parameter corresponding to the time period according to the current time;

[0088] S004: Adjust the water temperature in the first water pipeline and the water temperature in the second water pipeline based on the obtained first water temperature parameter and second water temperature parameter.

[0089] As described in the above steps S001 - S004, the water usage requirements of the user at different time periods are recorded (for example, the hot water requirement in the morning and the warm water requirement in the evening). The system can adjust the working states of the refrigeration and heating units in advance for each independent time period, thereby reducing the response time and energy consumption. The system collects the required water outlet temperature within each time period through the user input interface (such as a smartphone APP, a touch screen, or an Internet of Things interface). The time period division can be flexibly set according to granularities such as hours and half - hours. The data input method can be preset, for example, water at 70°C is required from 8 - 9 am, and water at 50°C is required from 12 - 13 pm, etc. According to the temperature requirements provided by the user, the system generates corresponding refrigeration and heating parameters for each time period. By reducing the idling time of heating or refrigeration and reducing energy waste, when the user uses water in each time period, water at the expected temperature can be directly obtained, improving convenience. The temperature requirements for each time period can be freely set to meet the personalized needs of different family members or usage scenarios.

[0090] In one embodiment, the water path of the water supply device further includes a communication module, and the communication module is used to connect to a terminal. The step S1 of obtaining the preset water outlet temperature and the water outlet signal set by the user includes:

[0091] S101: Connect to the user's terminal through the communication module;

[0092] S102: Receive the parameter information transmitted by the user to obtain the preset water outlet temperature and the water outlet signal set by the user.

[0093] As described in the above steps S101 - S102, the introduction of the communication module allows the water supply device to interact with the user's water supply device wirelessly or by wire. The supported communication protocols may include Wi - Fi, Bluetooth, Zigbee, etc. Through this connection, the user can set or adjust the operating parameters of the water supply device on the terminal water supply device. This enables the user to set or control the water supply device without being restricted by space (such as in the bedroom or office), improving convenience.

[0094] In one embodiment, the water path of the water supply device further includes a fifth water pipeline and a warm water tank. The water inlet of the warm water tank is connected to the first water pipeline. One end of the fifth water pipeline is connected to the water inlet of the warm water tank, and the other end of the fifth water pipeline is connected to the third water pipeline. A fourth valve is also provided on the fifth water pipeline. After the step S4 of obtaining the preset water outlet temperature and the water outlet signal set by the user, the following steps are further included:

[0095] S511: Determine whether the preset water outlet temperature is greater than the preset temperature value;

[0096] S512: If it is greater than a preset temperature value, then in response to the water outlet signal, obtain the first temperature in the first water pipeline and the fourth temperature in the warm water tank;

[0097] S513: Determine the first control parameter of the first valve and the fourth control parameter of the fourth valve based on the first temperature and the fourth temperature;

[0098] S514: Control the first valve based on the first control parameter of the first valve, and control the fourth valve based on the fourth control parameter of the fourth valve, so that the water discharged from the third water pipeline is the preset water outlet temperature.

[0099] As described in the above steps S511 - S514, a fifth water pipeline and a warm water tank are introduced, and a complex temperature control logic is realized by adding a fourth valve. This design allows the water supply device to manage the water temperature more flexibly. Especially when the target temperature is higher than a certain preset value, by using warm water to improve efficiency and accuracy, the temperature can be more effectively adjusted when there is a demand for warm water (i.e., the preset water outlet temperature is relatively high). This design mixes hot water and warm water, making the water outlet temperature quickly tend to the required target, reducing energy consumption and reducing the response time and power of the heating unit.

[0100] The present invention also provides a control device for a water supply device, which is used to control the water supply device. The water supply device includes: a water supply device waterway, and the water supply device waterway includes: a first water pipeline, a second water pipeline, and a third water pipeline. The first water pipeline and the second water pipeline are respectively communicated with the third water pipeline. A first valve is arranged on the first water pipeline and / or a second valve is arranged on the second water pipeline. The device is configured to implement the steps of the water supply device control method described in any one of the above.

[0101] The beneficial effects of the present invention: By adjusting the opening degrees of the hot water and cold water valves based on the valve control parameters, the water supply device system can accurately control the water outlet temperature. Combining with the closed-loop control technology, the system can dynamically adjust the parameters during operation to ensure that the water outlet temperature is always stable at the target value set by the user, realizing more flexible water temperature control, enabling the water supply device to quickly switch the water temperature in a short time and meet the drinking water needs in different scenarios.
