[0071] The water inlet module 800 is connected to the inlet of the water outlet module 200 to form a normal temperature water path, that is, when the water outlet module 200 does not include the tap control valve 16, the water path from the water inlet 80, the second control valve 12, the fifth control valve 15, the fourth control valve 14 to the tap 25 is used as a normal temperature water path. When the water outlet module 200 also includes the tap control valve 16, the water path from the water inlet 80, the second control valve 12, the fifth control valve 15, the fourth control valve 14, the tap control valve 16 to the tap 25 is used as a normal temperature water path.

[0074] See also Figure 5 For the heating module 500 and the heat storage module 400 being connected to form a hot water storage circuit, an optional implementation method is: the water circuit formed from the water inlet 80, the heater 51, the fourth control valve 14, the exhaust control valve 17 to the hot tank is used as a hot water storage circuit.

[0075] It can be understood that the hot tank is provided with an exhaust hole 42, through which the hot tank discharges excess gas inside the hot tank.

[0076] Optionally, the gas exhausted from the hot tank through the exhaust hole 42 is exhausted to the external environment through the exhaust port 26 of the water outlet module 200.

Whether the cleaning agent in the cleaning agent storage box is delivered is controlled by controlling the on-off of the dosage delivery control valve, and the delivery amount of the cleaning agent in the cleaning agent storage box is controlled by controlling the conduction time of the dosage delivery control valve. It is understandable that the number of the dosage delivery control valves is multiple, so that cleaning agent can be delivered to each module and the water inlet module separately.

[0081] Optionally, the control module 300 includes: a memory, a processor, and a computer program stored in the memory and executable on the processor, and the processor implements the steps of the water supply device temperature control method described in the present application when executing the computer program.

[0084] The present invention is described in detail below through specific embodiments.

[0085] See also Figure 2 As shown, Figure 2 A flow chart of a method for controlling the temperature of a water supply device provided in an embodiment of the present invention is provided. The method is used to control a water supply device. The method includes:

[0086] S1. Obtaining a water outlet instruction, which includes a target temperature;

[0087] The water outlet instruction is an instruction to control the water outlet module 200 to discharge water. The target temperature is the temperature of the water discharged by the water outlet module 200 that the user wants. The target temperature can be a specific value or a temperature range to adapt to different usage scenarios and user needs.

[0088] Specifically, the user can trigger the water outflow command through the buttons on the water supply device, the user can also input the water outflow command through the touch screen on the water supply device, the user can also input the water outflow command through the client that communicates with the water supply device, and the user can also send the water outflow command to the server through a third-party application, and the server will send the water outflow command to the program file that implements this application.

[0089] The client may include but is not limited to: various personal computers, laptops, smart phones, tablet computers, portable wearable devices.

[0090] The server may be a server.

[0091] S2. Determine the cold and hot water flow ratio and the expected flow rate according to the target temperature;

[0092] Specifically, after receiving the water outlet instruction, the cold and hot water mixing ratio required to achieve the target temperature in the water outlet instruction is calculated. The required cold and hot water flow ratio is calculated based on the difference between the target temperature and the current water outlet temperature of the water supply device and the heat exchange characteristics of the water supply device.

[0093] The expected flow rate refers to the water flow rate expected by the user, which depends on the usage scenario, such as showering, hand washing, washing and kitchen water use.

[0094] Optionally, an adaptive algorithm can automatically adjust the ratio and flow rate of hot and cold water based on real-time feedback from users and historical data to achieve more precise temperature control. Flow sensors and temperature sensors are introduced to monitor and adjust the flow of hot and cold water in real time in response to changes in target temperature.

[0095] S3. Determine the water control instruction based on the ratio of hot and cold water flow and the expected flow rate;

[0096] Specifically, the cold and hot water flow ratio and the desired flow rate are converted into specific control instructions, which will be sent to the control system of the water supply device to adjust the valve opening and the water pump speed.

[0097] The control instructions include, but are not limited to, the opening percentage of the valve, the operating speed of the pump, the position of the temperature control valve, and the configuration of the heating module, the configuration of the heat storage module, and the configuration of the refrigeration module.

[0098] Optionally, input data from multiple sensors and optimize control instructions in real time to respond to sudden flow or temperature changes. Introduce artificial intelligence algorithms to adjust control instructions in advance through pattern recognition and predictive analysis to reduce temperature fluctuations.

[0099] S4. Control the water supply device to discharge water based on the water discharge control instruction;

[0100] Specifically, the water outlet control instructions are executed to control the water outlet process of the water supply device to ensure that the outlet water temperature and flow rate meet the user's requirements. For example, the flow between the various water channels in the water supply device is controlled, and the heating module, heat storage module, and refrigeration module are controlled to work. In addition, the real-time temperature and flow rate of the outlet water are monitored to ensure that they are within the set parameter range, and adjustments are made when necessary.
