[0024] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0025] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0026] At present, when users need hot water, they often need to open the water outlet first, then adjust the temperature of the gas water heater, and then repeatedly adjust the water volume at the outlet. During this process, it is difficult for the water temperature and water volume to reach the ideal state quickly. Therefore, users need to repeatedly debug the mixing valve, resulting in a poor user experience.

[0027] The main solution of the present application is: in response to the triggering action of the regulating component, determining the water demand corresponding to the triggering action; determining the whole machine control parameters according to the difference between the collected water output parameters and the water demand; and sending the whole machine control parameters to the water heater based on the communication module to control the water heater to adjust the combustion state according to the whole machine control parameters.

[0028] This application collects the outlet temperature, compares the temperature with the set temperature of the water demand, and adjusts the cold water circulation and the combustion state of the water heater according to the temperature difference to achieve the most efficient operation mode to produce hot water quickly, and provides bathing solutions in the fastest and best way through the intelligent control terminal.

[0029] It should be noted that the execution subject of this embodiment can be a water mixing terminal, or a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a water mixing terminal capable of realizing the above functions, etc., and this embodiment does not specifically limit this. The following takes the water mixing terminal as the execution subject as an example to illustrate this embodiment and the following embodiments.

[0030] An embodiment of the present application proposes a hot water system, including a water heater, a mixing water terminal, and a hot water pipe and a cold water pipe respectively connected to the mixing water terminal, one end of the hot water pipe is connected to the hot water inlet of the mixing water terminal, and the other end is connected to the hot water outlet of the water heater, one end of the cold water pipe is connected to the cold water inlet of the mixing water terminal, and the other end is connected to the cold water inlet of the water heater; the hot water pipe and the cold water pipe are connected through a water use channel at the mixing water terminal, and the water use channel includes a first branch and a second branch, the first branch is provided with a circulation switch, and the second branch is provided with a mixing water proportional valve, and the mixing water proportional valve is used to limit the flow of the second branch to be less than the starting flow of the water heater.

[0031] As an optional implementation, the water mixing terminal 100 refers to Figure 1 As shown, the water mixing terminal 100 includes a water mixing proportional valve 104 , a regulating component and a communication module 105 , and the water mixing terminal is communicatively connected with the water heater 200 via the communication module 105 .

[0032] As an optional implementation, the adjustment component may be at least one of the mechanical knob 109 , the display module 108 and the identification module, and the identification module is communicatively connected with the water mixing terminal 100 .

[0033] Furthermore, the water mixing terminal 100 further includes a hot water inlet 101 and a cold water inlet 103, wherein the hot water inlet 101 is connected to the hot water pipe 400, and the cold water inlet is connected to the cold water pipe 300. The hot water inlet 101 and the cold water inlet 103 form a first branch through a circulation switch 102, and the first branch forms a circulation pipeline through the hot water pipe 400, the cold water pipe 300 and the water heater 200 to achieve zero cold water circulation.

[0034] Furthermore, the water mixing terminal 100 further includes a temperature detection module 106 and a water mixing outlet 107, and the temperature detection module 106 is used to collect the outlet temperature of the water mixing outlet 107. The hot water inlet 101 and the cold water inlet 103 are connected to the water mixing proportional valve 104, serving as the water inlet of the water mixing proportional valve 104, and the water mixing outlet 107 is connected to the water mixing proportional valve 104, serving as the water outlet of the water mixing proportional valve 104.

[0035] Furthermore, the water mixing terminal also includes a communication module, the communication module includes a processor and a first signal transmitter, and the water heater is provided with a first signal receiver that interacts with the first signal transmitter.

[0036] In this embodiment, the water mixing terminal calculates the whole machine control parameter, and then sends the whole machine control parameter to the water heater through the first signal transmitter of the communication module. The water heater receives the whole machine control parameter through the first signal receiver and adjusts its own combustion state according to the whole machine control parameter. The signal transmitter and the signal receiver can be a radio frequency communicator, an infrared communicator, or an ultrasonic communicator.

[0037] Furthermore, the communication module also includes a second signal receiver, and the water heater is provided with a second signal transmitter that interacts with the second signal receiver. The second signal transmitter is used to send the state parameters related to the combustion of the water heater to the water mixing terminal, and the water mixing terminal receives the state parameters according to the second signal receiver and renders them to the display module for display to show the combustion state of the water heater. This allows the user to pay attention to the combustion state of the water heater directly while bathing and adjust the combustion state of the water heater, without having to move to the location of the water heater for adjustment.

[0038] Based on this, the first embodiment of the present application proposes a control method for a water mixing terminal, wherein the water mixing terminal includes a water mixing proportional valve, a regulating component and a communication module, and the water mixing terminal is connected to the water heater through the communication module. Figure 2 The control method of the water mixing terminal includes steps S10 to S30: Step S10, in response to the triggering action of the regulating component, determining the water demand corresponding to the triggering action.

[0039] In this embodiment, the adjustment component is a component used by the user to operate the water mixing terminal, which can be a mechanical knob, an identification module, a display module, etc. The user inputs a control instruction to the water mixing terminal by operating the adjustment component. For example, a plurality of function buttons are provided on the operation panel of the water mixing terminal, corresponding to different operation modes. Trigger action refers to the actual operation behavior of the user on the adjustment component, such as pressing a certain button, turning the knob to a specific position, clicking or sliding on the touch screen, etc. When the user presses the button marked "comfort mode", this behavior is a trigger action. Water demand: the working mode determined by the water mixing terminal according to the user's trigger action, and the water demand includes but is not limited to the water flow rate and the set temperature. The water demand can also be several preset modes, including but not limited to "comfort mode", "energy saving mode" and "fast heating mode". In different modes, there are different preset standards for parameters such as the temperature and flow rate of the water outlet. In the "comfort mode", the preset water temperature may be 40°C and the water flow rate is 5L / min; while in the "energy saving mode", the preset water temperature may be 35°C and the water flow rate is 3L / min.

[0040] As an optional implementation, the water mixing terminal continuously monitors the status of the regulating component. Once a trigger action is detected in the regulating component, the water demand corresponding to the trigger action is accurately determined based on a pre-set mapping relationship. For example, when a user presses a button labeled "Comfort Mode", the water mixing terminal recognizes the trigger action and then determines the water demand as "Comfort Mode" based on the internally stored mapping table.

[0041] Step S20, determining the whole machine control parameters according to the difference between the collected water output parameters and the water demand.

[0042] In this embodiment, the water outlet parameters refer to the relevant physical parameters of the water flowing out of the water outlet, mainly including the water outlet temperature, water outlet flow rate, etc. These parameters are collected in real time by temperature sensors, flow sensors and other equipment installed near the water outlet. The temperature sensor can use a thermistor sensor to accurately measure the water temperature by detecting the change in resistance value caused by the change in water temperature; the flow sensor can use an electromagnetic flow sensor to measure the water flow rate using the electromagnetic induction principle. The difference value refers to the difference between the actual water outlet parameters collected and the standard parameters pre-set under the water demand. For example, in the "comfort mode", the set temperature is 40℃, and the actual water outlet temperature collected by the temperature sensor is 35℃, then the difference value of the water temperature is 40℃-35℃=5℃; the preset water flow rate is 5L / min, the actual collected water outlet flow rate is 4L / min, and the difference value of the water flow rate is 5L / min-4L / min=1L / min. The whole machine control parameters are a series of parameters used to control the combustion state of the water heater, mainly including combustion power, gas supply, etc. By adjusting these parameters reasonably, the heating capacity of the water heater can be changed, so that the water output parameters gradually approach the standard parameters under water demand. When the water temperature is lower than the preset value, it may be necessary to increase the combustion power and gas supply to increase the heating speed; when the water flow rate is too fast and the water temperature is difficult to maintain, it may be necessary to appropriately reduce the water flow rate and adjust the combustion power and gas supply accordingly to keep the water temperature stable.

[0043] As an optional implementation, the adjustment component is an identification module, which determines the water demand matching the user characteristics based on the collected user characteristics, and then determines the whole machine control parameters based on the difference between the water output parameters and the water demand.

[0044] As an optional implementation, the water demand determined according to the triggering action is adjusted to the outlet temperature accordingly, and then the adjusted temperature is used as the set temperature, the difference between the outlet temperature and the set temperature is determined, and the control parameters of the whole machine are determined.

[0045] As an optional implementation, in response to the triggering action of the regulating component, the water demand is determined to turn on the zero cold water mode, and then the hot water inlet and the cold water inlet are controlled to be connected to form a circulation pipeline to return the cold water to the water heater for heating. At this time, the outlet temperature in the water outlet parameters is lower than the set temperature, and the control parameters of the whole machine are determined according to the difference between the two.

[0046] As an optional implementation, in response to the triggering action of the regulating component, it is determined that the water demand is adjusted by the water outlet flow rate, and the adjusted flow rate is used as the set flow rate, and the difference between the set flow rate and the water outlet flow rate is determined to determine the control parameters of the whole machine.

[0047] As an optional implementation, if the water mixing terminal and / or the water heater is restarted, the water demand is determined to be the default set temperature and set flow rate. Then, the whole machine control parameters are determined according to the first difference between the water flow rate and the set flow rate, and the second difference between the water outlet temperature and the set temperature.

[0048] For example, the water mixing terminal uses sensors to collect water outlet parameters in real time, and then compares the collected parameters with the standard parameters under water demand to calculate the difference between the two. Then, according to the PID (Proportional-Integral-Derivative Controller) feedback adjustment, the whole machine control parameters that can effectively reduce the difference and make the water outlet parameters reach the standard are determined based on these difference values. For example, if the water temperature difference is 5°C, according to the PID feedback adjustment, for every 1°C difference, the combustion power needs to be increased by 10%, then the combustion power needs to be increased by 50% at this time; if the water outlet flow difference is 1L / min, for every 1L / min difference, the gas supply needs to be increased by 5%, then the gas supply needs to be increased by 5%.

[0049] Step S30: sending the whole machine control parameter to the water heater based on the communication module to control the water heater to adjust the combustion state according to the whole machine control parameter.

[0050] In this embodiment, the communication module is a key component for realizing the communication connection between the water mixing terminal and the water heater. Common communication methods include Wi-Fi, Bluetooth, ZigBee, etc. These communication methods have their own characteristics. Wi-Fi has fast communication speed and wide coverage, which is suitable for device communication in a home network environment; Bluetooth has low power consumption and convenient connection, which is suitable for short-range device connection; ZigBee has strong self-organizing network capability and high reliability, which is suitable for communication between multiple devices in a smart home system. In this embodiment, it is assumed that a Wi-Fi communication module is used. The module has a built-in Wi-Fi chip, which can be connected to a home wireless network and communicate with a water heater that is also connected to the network. Combustion state refers to the combustion state of the water heater during operation, mainly including the size of the combustion power, the amount of gas supply, etc. By adjusting the combustion state, the heating capacity of the water heater can be directly changed, thereby affecting the temperature and flow rate of the water outlet. When the water temperature needs to be increased, the combustion power and gas supply are increased to speed up the heating speed of the water heater; when the water temperature needs to be lowered, the combustion power and gas supply are reduced to reduce the heating speed.

[0051] As an optional implementation, the water mixing terminal will send the calculated whole machine control parameters to the water heater through the communication module. Taking the Wi-Fi communication module as an example, the water mixing terminal packages the whole machine control parameters according to a specific communication protocol, and then sends them to the water heater through the home wireless network. After receiving these parameters, the water heater adjusts its own combustion state according to the parameter content. For example, if the received control parameters increase the combustion power by 50% and the gas supply by 5%, the water heater will increase the firepower of the burner accordingly, increase the combustion power, and increase the gas supply to achieve the regulation of the outlet water temperature and flow.

[0052] This embodiment determines the water demand corresponding to the triggering action by responding to the triggering action of the regulating component; determines the whole machine control parameter according to the difference between the collected water output parameter and the water demand; sends the whole machine control parameter to the water heater based on the communication module to control the water heater to adjust the combustion state according to the whole machine control parameter. In this way, the user can get the appropriate water temperature without manually adjusting the water mixing terminal, thereby improving the user experience.

[0053] Based on any of the above embodiments, in Embodiment 2 of the present application, if the water outlet parameter is the water outlet temperature, the step of determining the whole machine control parameter according to the difference between the collected water outlet parameter and the water demand includes: Step S21, determining a temperature difference between the water outlet temperature and a set temperature in the water demand.

[0054] In this embodiment, the outlet temperature is collected by a high-precision thermistor temperature sensor installed at the outlet. This sensor uses the characteristic that the resistance value of the thermistor changes with temperature to convert the temperature signal into an electrical signal. After the electrical signal is amplified and filtered by the signal conditioning circuit, the analog signal is converted into a digital signal by the analog-to-digital converter (ADC), and finally transmitted to the microcontroller of the water mixing terminal, so as to accurately measure the real-time temperature of the water at the outlet. Set temperature: It is one of the important preset parameters of water demand and is stored in the non-volatile memory (such as EEPROM) of the water mixing terminal. Different operating modes correspond to different set temperatures. For example, the set temperature of the "comfort mode" is 40°C, and the set temperature of the "fast heating mode" may be 45°C. The microcontroller of the water mixing terminal reads the outlet temperature data collected by the temperature sensor, and compares it with the set temperature stored in the memory under the water demand, and calculates the difference between the two by subtraction operation. This difference is the temperature difference value. For example, if the water demand is "comfort mode", the set temperature is 40℃, and the temperature sensor measures the outlet temperature as 35℃, then the temperature difference is 40℃-35℃=5℃.

[0055] Step S22, calculating a heat gap parameter according to the temperature difference value and the water flow rate in the water demand.

[0056] In this embodiment, the water flow rate: as another preset parameter of water demand, is measured by an electromagnetic flow sensor. According to Faraday's law of electromagnetic induction, when the conductive water flows through the induction area generated by the magnetic field, an induced electromotive force proportional to the flow rate will be generated in the water flow. After the sensor processes and converts the induced electromotive force signal, it transmits it to the microcontroller of the water mixing terminal, and the microcontroller calculates the water flow rate according to the signal strength. The calculation of the heat gap parameter is based on the basic principle of heat transfer formula Q=cmΔT (where Q represents heat, c is the specific heat capacity of water, which is a constant of about 4.2×10³J / (kg×℃), m is the mass of water, and ΔT is the temperature change). In actual calculations, since the mass m of water per unit time is proportional to the water flow rate (m=ρV, ρ is the density of water, which is also a constant, and V is the volume of water per unit time, that is, the water flow rate), the heat required to supplement or reduce the water temperature to reach the set temperature per unit time can be calculated based on the known temperature difference value and the water flow rate. This heat value is the heat gap parameter. Assuming that the specific heat capacity of water is c = 4.2×10³J / (kg×℃), the water flow rate in the water demand is 5L / min, which is converted into a mass flow rate of about 5kg / min, and the temperature difference is 5℃, the heat gap parameter Q can be calculated according to the formula = 4.2×10³J / (kg×℃)×5kg / min×5℃=1.05×10 5 J / min.

[0057] Step S23: generating the whole machine control parameter based on the heat gap parameter and the current operating power of the water heater.

[0058] In this embodiment, the current operating power of the water heater: This information is obtained by the water heater's own control system through the power detection circuit. The power detection circuit generally measures the current and voltage and uses the power calculation formula P=UI (P is power, U is voltage, and I is current) to obtain the current operating power. Then, the water heater transmits the current operating power information to the water mixing terminal through a communication link. After receiving the information, the microcontroller of the water mixing terminal combines the previously calculated heat gap parameters and uses the PID feedback adjustment pre-written in the internal program to determine the whole machine control parameters. For example, if the heat gap is large and the current water heater operating power is low, in order to make the water temperature reach the set temperature within a reasonable time, the microcontroller will calculate the combustion power that needs to be increased and the corresponding gas supply adjustment value as the whole machine control parameters according to the PID feedback adjustment. If the heat gap is a positive value, it means that the current water temperature is lower than the set temperature, and the combustion power and gas supply may need to be increased; if it is a negative value, the combustion power and gas supply may need to be appropriately reduced. Assume that the current water heater operating power is 20kW (20000W), and according to the heat gap calculation, it is necessary to provide an additional 1.05×10 5 J of heat, the microcontroller calculates based on the PID feedback regulation that the combustion power needs to be increased by 50%, and the gas supply volume needs to be increased accordingly, for example, by 10%.

[0059] Optionally, before the step of determining the temperature difference between the water outlet temperature and the set temperature in the water demand, the step includes: detecting whether the mixing water proportioning valve is adjusted to the maximum opening of hot water; if it is adjusted to the maximum opening of hot water, executing the step of determining the temperature difference between the water outlet temperature and the set temperature in the water demand.

[0060] In this embodiment, the water mixing proportional valve is a three-way valve, which not only adjusts the ratio of hot and cold water mixing, but also adjusts the water flow rate. The maximum opening of hot water refers to the opening of the water mixing proportional valve adjusted to the maximum hot water flow rate. If the water mixing proportional valve is adjusted to the maximum opening of hot water, it indicates that the current water temperature is the highest that the user can obtain. At this time, the water mixing proportional valve also acts as a regulating component, indicating that the user needs to continue to increase the water temperature. At this time, the step of determining the temperature difference between the outlet temperature and the set temperature in the water demand is performed, and then the whole machine control parameters of the water heater are determined.

[0061] Optionally, the water mixing terminal further comprises a hot water inlet, a cold water inlet and a water outlet, and the hot water inlet and the cold water inlet form a circulation pipeline through a circulation switch. Figure 3 , Figure 3Steps S24, S25 and S26 are shown, after which the step of determining the temperature difference between the water outlet temperature and the set temperature in the water demand includes: Step S24, determining whether to execute a cold water circulation action according to the temperature difference value.

[0062] It should be noted that the water mixing terminal is provided with a hot water inlet, a cold water inlet and a water outlet. The hot water inlet and the cold water inlet form a circulation pipeline through a circulation switch. Since the hot water inlet is connected to the water heater, cold water circulation is realized. The water mixing terminal is also provided with a water mixing proportion valve. The water mixing proportion valve is connected to the hot water inlet, the cold water inlet and the water outlet to form a water outlet pipeline. A temperature detection module is provided at the water outlet to detect the outlet temperature. The water mixing proportion valve is a three-way valve. In addition to adjusting the hot and cold water mixing ratio, it also adjusts the water outlet flow rate.

[0063] In this embodiment, the water demand is the mode selected by the user in the water mixing terminal, or it is a memory mode associated with the user, or it can be a default mode. Different modes correspond to different set temperature and other parameters to adapt to different usage scenarios. The set temperature is the final water outlet temperature expected by the user, which is the control target value. The collected outlet temperature is the actual temperature of the current outflowing water measured and fed back in real time by the temperature detection module set at the outlet. The cold water circulation action is an operation that starts when the actual outlet temperature is lower than the set temperature, allowing the cold water in the hot water pipe to flow back to the water heater for reheating.

[0064] As an optional implementation, the water mixing terminal first obtains the water demand selected by the user, and then obtains the set temperature corresponding to the mode. At the same time, the water outlet temperature data transmitted by the temperature detection module is received in real time. Then, the collected water outlet temperature is compared with the set temperature. If the collected temperature is lower than the set temperature, it is determined that the cold water circulation action needs to be executed; if the collected temperature is equal to or higher than the set temperature, the cold water circulation action is not executed. For example, in the daily bathing mode, the set temperature is 38°C, and the water outlet temperature transmitted by the temperature detection module is 35°C. After comparison, the water mixing terminal determines that the cold water circulation action needs to be executed.

[0065] For example, the water demand setting temperature is 37° C. The temperature detection module detects that the water outlet temperature is 34° C. The water mixing terminal compares the two temperatures and determines to execute the cold water circulation action because 34° C. < 37° C.

[0066] Step S25, if the cold water circulation action is executed, adjust the opening of the circulation switch to control the circulation pipeline to open.

[0067] In this embodiment, the circulation switch is a device installed between the hot water inlet and the cold water inlet, and the opening of the circulation pipeline and the water flow are controlled by adjusting the opening. The opening refers to the degree of opening of the circulation switch, which determines the water flow rate of the circulation pipeline. The larger the opening, the larger the water flow and the faster the circulation; the smaller the opening, the smaller the water flow and the slower the circulation. The circulation pipeline is a passage formed by connecting the hot water inlet and the cold water inlet through the circulation switch, which is used to realize the return of cold water to the water heater for heating.

[0068] As an optional implementation, when the water mixing terminal determines to execute the cold water circulation action, it calculates the appropriate circulation switch opening according to the PID feedback adjustment and the difference between the current outlet temperature and the set temperature. For example, if the temperature difference is large, the cold water circulation speed needs to be accelerated, and a larger opening value is calculated; if the temperature difference is small, the opening can be appropriately reduced to save energy. Then, the water mixing terminal sends a control instruction to the circulation switch, adjusts its opening to the calculated value, opens the circulation pipeline, and the cold water begins to flow in the circulation pipeline and flows back to the water heater.

[0069] For example, it is determined that the cold water circulation action needs to be executed. At this time, the difference between the outlet temperature and the set temperature is 3°C. According to the PID feedback adjustment, it is calculated that the circulation switch opening should be 40%. The mixing water terminal sends a command to the circulation switch to adjust its opening to 40%, the circulation pipeline is opened, and the cold water begins to circulate.

[0070] Step S26, determining the whole machine control parameter according to the temperature difference value.

[0071] As an optional implementation, the water mixing terminal takes the set temperature as the core, combines water demand and ambient temperature and other factors, and uses PID feedback regulation to calculate the control parameters of the whole machine. For example, in the comfortable bathing mode, when the set temperature is high and the ambient temperature is low, the PID feedback regulation will calculate the need to increase the gas volume and fan speed to increase the combustion intensity and quickly increase the water temperature. After the calculation is completed, the water mixing terminal sends these parameters to the gas water heater. After receiving the parameters, the gas water heater adjusts the gas supply valve of the burner to change the gas output, and at the same time adjusts the fan speed to make the combustion more complete, thereby adjusting the combustion state and heating the water to the set temperature.

[0072] For example, the set temperature is 42°C and the ambient temperature is 10°C. The water mixing terminal adjusts according to the PID feedback and calculates that the gas volume needs to be increased by 30% and the fan speed needs to be increased by 20%. After sending these parameters to the gas water heater, the water heater adjusts the gas supply valve to increase the gas volume by 30%, and at the same time increases the fan speed by 20%, increasing the combustion intensity and quickly heating the water to 42°C.

[0073] Through the control method of the mixing water terminal in the above embodiment, it is possible to automatically judge and execute the cold water circulation action according to the user-set temperature and the actual water outlet temperature, reasonably control the opening of the circulation switch, and efficiently adjust the combustion state of the water heater to achieve fast, stable and energy-saving hot water supply, which greatly improves the user's bathing experience, avoids the tedious process of repeatedly adjusting the water temperature and water volume of traditional bathing equipment, and improves the convenience and comfort of hot water use.

[0074] Based on any of the above embodiments, the third embodiment of the present application proposes a control method for a water mixing terminal, where the water outlet parameter is the water outlet flow rate, and step S20 includes: Step S27, determining the flow difference between the water outlet flow and the set flow in the water demand.

[0075] In this embodiment, the water flow rate is collected by an electromagnetic flow sensor installed at the water outlet. The electromagnetic flow sensor works based on Faraday's law of electromagnetic induction. When the conductive water flows through the induction area generated by the magnetic field, an induced electromotive force proportional to the flow rate will be generated in the water flow. The sensor processes and converts the induced electromotive force signal and transmits it to the microcontroller of the water mixing terminal. The microcontroller calculates the water flow rate based on the signal strength. Set flow rate is one of the important preset parameters for water demand. Different operating modes correspond to different set flow rates. For example, the set flow rate of the "comfort mode" is 5L / min, and the set flow rate of the "fast heating mode" may be 6L / min. The microcontroller of the water mixing terminal reads the water flow rate data collected by the flow sensor, and compares it with the set flow rate stored in the memory under the water demand. The difference between the two is calculated by subtraction, and this difference is the flow difference value. For example, if the water demand is "comfort mode", the set flow rate is 5L / min, and the water flow rate measured by the flow sensor is 4L / min, then the flow difference value is 5L / min-4L / min=1L / min.

[0076] Step S28, calculating a heat gap parameter according to the flow difference value and a set temperature in the water demand.

[0077] In this embodiment, the calculation of the heat gap parameter is based on the basic principle of heat transfer formula Q=cmΔT (where Q represents heat, c is the specific heat capacity of water, which is about 4.2×10³J / (kg×℃), m is the mass of water, and ΔT is the temperature change). When the flow difference value and the set temperature are known, since the mass m of water per unit time is proportional to the water flow rate (m=ρV, ρ is the density of water, which is about 1kg / L, and V is the volume of water per unit time, that is, the water flow rate), the amount of heat required to supplement or reduce the water temperature to reach the set temperature and the flow rate to reach the set flow rate per unit time can be calculated. This heat value is the heat gap parameter. Assuming that the specific heat capacity of water is c=4.2×10³J / (kg×℃), the set temperature in the water demand is 40℃, and the flow difference value is 1L / min, the mass flow difference converted to is about 1kg / min (the density of water is approximately 1kg / L). If the actual water temperature is 35℃, and the water temperature needs to be raised to the set temperature of 40℃, the temperature change ΔT = 5℃. According to the formula, the heat gap parameter Q = 4.2×10³J / (kg×℃)×1kg / min×5℃=2.1×10 4 J / min.

[0078] Step S29: generating the whole machine control parameter based on the heat gap parameter and the current operating power of the water heater.

[0079] In this embodiment, after receiving the information, the microcontroller of the water mixing terminal uses the PID feedback adjustment pre-programmed in the internal program to determine the control parameters of the whole machine, in combination with the previously calculated heat gap parameters. For example, if the heat gap is large and the current water heater operating power is low, in order to make the water temperature and flow reach the set standards within a reasonable time, the microcontroller will calculate the combustion power that needs to be increased and the corresponding gas supply adjustment value based on the PID feedback adjustment as the whole machine control parameters. If the heat gap is a positive value, it means that the current water temperature or flow does not meet the set requirements, and the combustion power and gas supply may need to be increased; if it is a negative value, the combustion power and gas supply may need to be appropriately reduced. Assuming that the current water heater operating power is 10kW (1×10 4 W), and according to the heat gap calculation, an additional 2.1×10 4 J of heat, the microcontroller calculates based on the PID feedback regulation that the combustion power needs to be increased by 20%, and the gas supply volume needs to be increased accordingly, for example, by 8%.

[0080] In this embodiment, the user's needs are determined by the user adjusting the water output parameters, and then the whole machine control parameters of the water heater are determined, so that the water heater can quickly respond to the user's needs.

[0081] Based on any of the above embodiments, the fourth embodiment of the present application proposes a control method for a water mixing terminal, step S10, comprising: Step A10, in response to the adjustment information of the mechanical knob, determining the water demand according to the gear position of the mechanical knob and the adjustment information.

[0082] In this embodiment, the mechanical knob is a physical control component installed on the water mixing terminal, and the user can operate it by rotating it. The adjustment information refers to the scale information of the user rotating the mechanical knob. Different gears of the mechanical knob correspond to different adjustment functions, including but not limited to adjusting the set temperature, adjusting the bathing mode, adjusting the water inlet and outlet, and turning the water on and off.

[0083] As an optional implementation, when the mechanical knob is in the first gear, the user rotates the mechanical knob, and the rotation sensor inside the mechanical knob captures the rotation scale information. This information is transmitted to the mixing terminal of the water mixing terminal. The corresponding relationship between the rotation scale and the set temperature is pre-set in the mixing terminal. For example, the set temperature increases or decreases by 1°C for each rotation of one scale. The mixing terminal adjusts the set temperature value according to the preset relationship based on the received rotation scale information.

[0084] For example, the initial set temperature is 38°C, and the mechanical knob is in the first gear. The user rotates the knob clockwise by 3 scales. According to the preset correspondence, each scale corresponds to a temperature increase of 1°C, and the water mixing terminal adjusts the set temperature to 38+3=41°C.

[0085] As an optional implementation, the mechanical knob can be rotated to different positions, one of which is used to adjust the bathing mode. The adjustment information is still the scale information of rotating the mechanical knob. Bathing modes are different pre-set operating modes, such as daily bathing mode, comfortable bathing mode, energy-saving mode, etc., and each mode corresponds to a different combination of operating parameters. When the mechanical knob is in the position for adjusting the bathing mode, the user rotates the mechanical knob, and the rotation sensor transmits the rotation scale information to the mixing water terminal. The correspondence between different rotation scales and bathing modes is stored in the mixing water terminal. For example, rotating to the first scale position corresponds to the daily bathing mode, rotating to the second scale position corresponds to the comfortable bathing mode, etc. The mixing water terminal switches to the corresponding bathing mode according to the received rotation scale information.

[0086] For example, the mechanical knob is in the gear position of adjusting the bathing mode, and is initially in the daily bathing mode. The user rotates the knob counterclockwise to the second scale position, and the water mixing terminal switches the bathing mode to the comfortable bathing mode according to the preset corresponding relationship.

[0087] As an optional implementation, the mechanical knob has a gear specifically for adjusting the amount of water inlet and outlet. The adjustment information is the scale information of rotating the mechanical knob. The amount of water inlet and outlet refers to the amount of hot water and cold water flowing into the water mixing terminal and the amount of water flowing out after mixing. This step adjusts the amount of water inlet and outlet according to the rotation scale with the help of the rotation operation of the mechanical knob. When the mechanical knob is in the gear for adjusting the amount of water inlet and outlet, the user rotates the mechanical knob, and the rotation sensor sends the rotation scale information to the water mixing terminal. The corresponding relationship between the rotation scale and the amount of water inlet and outlet is set in the water mixing terminal. For example, the amount of water inlet and outlet increases or decreases by a certain proportion for each rotation of one scale. The water mixing terminal adjusts the amount of water inlet and outlet by adjusting the valve opening in the water mixing terminal and other methods according to the received rotation scale information.

[0088] For example, the initial water inlet and outlet volume is a default value, and the mechanical knob is in the gear position for adjusting the water inlet and outlet volume. The user rotates the knob clockwise by 2 scales. According to the preset correspondence, each scale corresponds to a 10% increase in the water inlet and outlet volume, and the water mixing terminal adjusts the water inlet and outlet volume to 1+2×10%=120% of the default value.

[0089] As an optional implementation, the mechanical knob has a gear position for controlling the water on / off operation. The adjustment information is the scale information of rotating the mechanical knob. Turning water on and off refers to controlling the water circuit of the water mixing terminal to be turned on or off. This step realizes the opening or closing of the water circuit according to the rotation scale by rotating the mechanical knob. When the mechanical knob is in the gear position for adjusting the water on / off, the user rotates the mechanical knob, and the rotation sensor transmits the rotation scale information to the water mixing terminal. A specific rotation scale is set in the water mixing terminal to correspond to the opening or closing of the water circuit. For example, rotating to a certain scale opens the water circuit, and rotating to another specific scale closes the water circuit. The water mixing terminal controls the valve in the water mixing terminal to open or close according to the received rotation scale information, thereby realizing the water on / off operation.

[0090] For example, the mechanical knob is in the gear position of adjusting the water switch, and the initial water path is in a closed state. The user rotates the knob to a preset opening scale position, and after the water mixing terminal receives the scale information, it controls the valve to open and the water path to open.

[0091] Through the operations in the above embodiments, the user can conveniently adjust the set temperature, bathing mode, water inlet and outlet, water on / off and other parameters of the water mixing terminal through the mechanical knob, which improves the convenience of operation and user experience.

[0092] Based on any of the above embodiments, the present application further provides a fourth embodiment. In this embodiment, step S10 includes: responding to the user characteristics collected by the identification module, determining the water demand according to the user characteristics. Specifically: Step B10: collecting user features based on the recognition module.

[0093] In this embodiment, the identification module is a device installed on the water mixing terminal, which has the function of collecting user feature information. The functions implemented by the identification module include at least one of fingerprint recognition, ultrasonic recognition, foot recognition, infrared recognition, gravity sensing recognition, blood pressure and blood oxygen recognition, and may have other functions, which are not described in this embodiment. User features refer to physical features that can uniquely identify the identity of a user or reflect the specific habits of a user, such as fingerprints, facial features, irises, etc.

[0094] As an optional implementation, when the user approaches the water mixing terminal, the recognition module automatically starts. If the recognition module is a fingerprint recognition device, the user places the finger in the fingerprint recognition area, and the recognition module scans and records the fingerprint's lines, breakpoints and other features; if it is a facial recognition device, it will capture the user's facial image through the camera, extract facial contours, facial features and other features; if it is an iris recognition device, it will use near-infrared light to illuminate the eyes and collect iris texture information. The collected user feature information will be converted into a digital signal and stored in the water mixing terminal of the water mixing terminal.

[0095] Exemplarily, a user stands in front of a water mixing terminal, and the camera of the facial recognition module captures the user's facial image. After image processing and feature extraction, the user's facial feature data, such as the distance between the eyes, the shape of the nose, etc., is obtained, and the data is stored in the system.

[0096] Step B20, determining a memory mode matching the user feature.

[0097] In this embodiment, the memory mode is an operation mode pre-stored in the water mixing terminal system and associated with the user characteristics of a specific user. Each memory mode contains a series of personalized settings for the user, such as set temperature, bathing mode, water inlet and outlet, and other parameters. This step compares the collected user characteristics with the feature templates stored in the system to find the matching memory mode.

[0098] As an optional implementation, the water mixing terminal compares the user feature data collected in step B10 with the user feature templates pre-stored in the database. The comparison process uses a similarity calculation algorithm to calculate the similarity score between the collected feature and each template. When the similarity score exceeds a preset threshold, it is considered that the user feature matches the corresponding template, thereby determining the memory mode associated with the template.

[0099] For example, the system stores the facial feature template of user A and the corresponding memory mode (set temperature 40°C, comfortable bathing mode, moderate water inflow and outflow). When the similarity score between the collected facial features and the template of user A reaches 90% (assuming the threshold is 80%), the matching memory mode is determined to be the memory mode of user A.

[0100] Step B30, using the memory mode as the water demand.

[0101] In this embodiment, water demand is the operating mode adopted by the water mixing terminal in the current usage scenario, which determines the various operating parameters of the water mixing terminal. This step sets the memory mode determined in step B20 as water demand, so that the water mixing terminal operates according to the parameters of this mode.

[0102] As an optional implementation, the water mixing terminal loads the relevant parameters of the determined memory mode, such as the set temperature, bathing mode, water inlet and outlet, etc., into the operation control program of the water mixing terminal. Subsequently, the water mixing terminal performs corresponding adjustments and controls according to these parameters, such as adjusting the heating power of the water heater, the opening of the water mixing proportional valve, etc., to meet the personalized needs of users.

[0103] For example, if the determined memory mode is a set temperature of 40°C, a comfortable bathing mode, and moderate water inlet and outlet volumes, the mixing water terminal will set the set temperature to 40°C, select the comfortable bathing mode, and adjust the opening of the inlet and outlet valves to achieve moderate water inlet and outlet volumes, and then control the water heater and the mixing water terminal to operate according to these parameters.

[0104] Through the method in the above embodiment, the water mixing terminal can automatically identify and adopt a matching memory mode as the water demand according to the user characteristics of the user, thereby realizing personalized hot water supply and further improving the user experience.

[0105] Based on any of the above embodiments, the present application further provides a fifth embodiment. In this embodiment, step S10 includes: in response to the touch information received by the display module, determining the water demand according to the touch information. Specifically: Step C10, determining setting parameters in response to the touch information received by the display module, wherein the setting parameters include at least one of bathing function, temperature, and flow rate.

[0106] In this embodiment, the display module is a device installed on the water mixing terminal, which is used to display various types of information and receive user click operations. Touch information refers to the signal generated by the user clicking on the display module screen with a finger or a touch pen. The setting parameters are parameters set by the user through the click operation and used to adjust the operating state of the water mixing terminal, including bathing functions (such as daily bathing, comfortable bathing, massage bathing and other different modes), temperature (user's desired hot water temperature), flow (water flow rate of the water mixing terminal) and at least one. This step determines the relevant parameters set by the user based on the touch information received by the display module.

[0107] As an optional implementation, when the user taps on the display module, the touch sensing layer of the display module captures the tap position information and converts the information into an electrical signal and transmits it to the mixing terminal of the mixing water terminal. The mixing water terminal parses the setting parameters selected by the user based on the correspondence between the pre-set tap position and the setting parameters. For example, if a certain area on the display module corresponds to the "comfortable bathing" function, the user clicks on the area, and the mixing water terminal determines that the setting parameter of the bathing function is "comfortable bathing"; if the user taps in the temperature adjustment area, the mixing water terminal determines the temperature parameter set by the user based on the number of taps or the sliding distance.

[0108] For example, there is a temperature adjustment area on the display module, and the user slides his finger upwards to perform a tapping operation in the area. Each time the finger is slid, the temperature setting value increases by 1°C. The user slides three times, and after the water mixing terminal receives the touch information, it determines that the temperature in the setting parameter is the current basic temperature plus 3°C.

[0109] Step C20, determining the water demand according to the setting parameters and associating it with the memory mode of the current user.

[0110] In this embodiment, water demand is the operating mode adopted by the water mixing terminal at the current moment, which is determined based on the setting parameters. The memory mode is a personalized operating mode stored by the system for the current user. After the current setting parameters are associated with the memory mode, it can be quickly called the next time the user uses it. This step determines the water demand based on the parameters set by the user and stores it as the memory mode of the current user, which is convenient for the user to use later.

[0111] As an optional implementation, the water mixing terminal searches for a matching water demand from a preset mode library according to the setting parameters determined in step C10. For example, if the setting parameters are a "comfortable bathing" function, a temperature of 40°C, and a moderate flow rate, the water mixing terminal finds a "comfortable bathing mode" that meets these parameter combinations in the mode library as the water demand. The water mixing terminal then associates the water demand with the current user and stores it as a memory mode for the user. The storage process may involve writing the relevant parameters into a user-specific storage area so that they can be quickly called up the next time the user is identified.

[0112] For example, the user sets the parameters of "daily bathing" function, temperature 38°C, and large flow rate. The water mixing terminal determines the matching "daily high-flow bathing mode" in the mode library as the water demand, and associates the mode with the current user and stores it as the user's memory mode. The next time the user uses the water mixing terminal, the system can directly call this memory mode.

[0113] Through the method in the above embodiment, the user can conveniently set parameters through the display module, and then determine and store a personalized operating mode, thereby improving the convenience and personalization of the use of the water mixing terminal.

[0114] Based on any of the above embodiments, the present application further provides a sixth embodiment. In this embodiment, the control method of the water mixing terminal further includes the steps of: Step C30, in response to the health detection instruction received by the display module, calling the recognition module to collect user characteristics.

[0115] In this embodiment, the display module is a component on the water mixing terminal for displaying information and receiving user instructions. The user can issue various instructions by operating on the display module. The health detection instruction is an instruction issued by the user to start the user health detection by performing a specific operation on the display module (such as clicking the health detection button). The identification module is a device with the function of collecting user characteristics, which can collect user characteristic information such as fingerprints, facial features, heart rate, blood pressure, etc. This step is to trigger the identification module to start collecting user characteristics after the display module receives the health detection instruction.

[0116] As an optional implementation, when the user clicks on an icon or button related to health detection on the display module, the display module converts the received click signal into an electrical signal and transmits it to the mixing terminal of the mixing terminal. After receiving the electrical signal, the mixing terminal recognizes that this is a health detection instruction, and then sends a start signal to the recognition module. After receiving the start signal, the recognition module starts to collect user features according to the preset collection process. For example, if the recognition module includes a heart rate detection sensor, it will detect heart rate data by contacting the user's skin; if it includes a facial recognition camera, it will capture facial images for subsequent analysis.

[0117] Exemplarily, the user clicks the "Health Check" button on the display module, the display module transmits the click information to the water mixing terminal, the water mixing terminal sends a start signal to the identification module, and the infrared sensor in the identification module starts to detect the user's body temperature data.

[0118] Step C40, generating and displaying user health data according to the user characteristics.

[0119] In this embodiment, the user characteristics are the user's body-related characteristic data collected by the identification module. The user health data is a series of data reflecting the user's health status, such as heart rate value, blood pressure value, body temperature, etc., obtained through model analysis and calculation based on the collected user characteristics. This step processes and analyzes the collected user characteristics, generates user health data, and displays it on the display module.

[0120] As an optional implementation, the identification module transmits the collected user characteristic data to the mixed water terminal. The mixed water terminal pre-stores algorithms and models for analyzing the relationship between user characteristics and health data. The mixed water terminal uses these algorithms and models to process and analyze the user characteristic data and calculate the corresponding user health data. For example, based on the collected heart rate fluctuation characteristics, the user's average heart rate, heart rate variation range and other data are calculated through the heart rate analysis algorithm. Then, the mixed water terminal sends the generated user health data to the display module, and the display module displays these data to the user in an intuitive manner (such as numbers, charts, etc.).

[0121] For example, after the recognition module collects the user's heart rate characteristic data, the mixed water terminal calculates that the user's current heart rate is 75 beats per minute. The mixed water terminal sends the heart rate data to the display module, and the display module displays "Heart rate: 75 beats / minute" in digital form on the screen.

[0122] Through the method in the above embodiment, the user can conveniently perform health checks on the water mixing terminal and obtain his or her own health data, thereby increasing the functional diversity and practicality of the water mixing terminal.

[0123] Based on any of the above embodiments, the present application further provides embodiment 7. In this embodiment, after step S24, the following steps are further included: Step D10, if the cold water circulation action is not performed, the whole machine control parameters are determined according to the set temperature and the water outlet temperature to control the water heater to adjust the combustion state according to the whole machine control parameters.

[0124] In this embodiment, the cold water circulation action refers to the operation initiated by the water mixing terminal to make the cold water in the hot water pipe flow back to the water heater through the circulation pipeline for reheating when the actual temperature of the water outlet is lower than the set temperature. The set temperature is the desired final water outlet temperature set by the user in the water mixing terminal. The water outlet temperature is the actual temperature of the water flow at the water outlet measured and fed back in real time by the temperature detection module. The whole machine control parameters are a series of parameters for controlling the combustion state of the gas water heater calculated based on the set temperature, the water outlet temperature and other related factors (such as ambient temperature, etc.), including gas volume, fan speed, etc. Controlling the water heater to adjust the combustion state means that the water mixing terminal sends the calculated whole machine control parameters to the gas water heater, and the water heater adjusts the gas supply and fan operation of the burner according to these parameters, changes the combustion intensity, and accurately controls the water temperature. When it is determined that the cold water circulation action does not need to be performed, this step determines the appropriate whole machine control parameters based on the temperature data, so that the water heater adjusts the combustion state to meet the set temperature.

[0125] As an optional implementation, when the water mixing terminal determines that the cold water circulation action is not to be performed, the set temperature and the outlet temperature will be obtained. Then, combined with other relevant factors such as the current ambient temperature, the pre-set PID feedback adjustment is used to calculate the control parameters of the whole machine. For example, if the difference between the set temperature and the outlet temperature is small, it means that the current water temperature is close to the set temperature, and the PID feedback adjustment will calculate a smaller gas volume and a moderate fan speed; if the difference is large, it is necessary to increase the gas volume and increase the fan speed to quickly increase the water temperature. After the calculation is completed, the water mixing terminal sends these parameters to the gas water heater. After receiving the parameters, the gas water heater adjusts the gas supply valve of the burner, changes the gas output, and adjusts the fan speed to make the combustion more complete, thereby adjusting the combustion state and heating the water to the set temperature.

[0126] For example, the set temperature is 40°C, the outlet temperature is 38°C, and the ambient temperature is 20°C. The water mixing terminal adjusts according to the PID feedback and calculates that the gas volume needs to be increased by 10% and the fan speed needs to be increased by 5%. After sending these parameters to the gas water heater, the water heater adjusts the gas supply valve to increase the gas volume by 10%, increases the fan speed by 5%, and fine-tunes the combustion intensity so that the water temperature gradually reaches 40°C.

[0127] Through the method in the above embodiment, when there is no need to perform cold water circulation, the mixing water terminal can accurately adjust the combustion state of the water heater according to the set temperature and the outlet temperature, ensuring that the output water temperature meets user needs, thereby improving the stability and energy saving of hot water supply.

[0128] Based on any of the above embodiments, the present application further provides an eighth embodiment. In this embodiment, before step S10, the following steps are included: Step E10, determining water demand in response to the water output instruction.

[0129] In this embodiment, the water output instruction is an instruction issued by the user to request the water mixing terminal to start discharging water by operating the water mixing terminal (such as turning on the faucet, pressing the water output button, etc.). As mentioned above, the water demand covers the modes manually selected by the user (such as daily bathing, comfort, energy saving, etc.), the memory mode automatically matched by the system based on the user's past usage habits, and the default mode. After receiving the water output instruction, this step determines the current operating mode that the water mixing terminal should adopt.

[0130] As an optional implementation, when the water mixing terminal receives the water outlet command, the water mixing terminal first checks whether the user has manually selected the operating mode. If the user manually specifies the operating mode through a control panel, a mechanical knob, or a display module, the mode is determined as the water demand. If the user does not manually select, the water mixing terminal will further query whether there is a memory mode associated with the current user, and if so, it will be used as the water demand. If there is neither a manual selection nor a matching memory mode, the water mixing terminal will use the default mode as the water demand.

[0131] Exemplarily, the user turns on the faucet and issues a water-out instruction. If the user has previously clicked and selected "Comfortable Bathing Mode" on the display module, the mixing water terminal will determine the "Comfortable Bathing Mode" as the water demand; if the user has not made a manual selection, but the system has stored the "Energy Saving Mode" last used by the user as a memory mode, the "Energy Saving Mode" will be determined as the water demand; if neither is met, the default "Daily Bathing Mode" will be used.

[0132] Step E20, adjusting the water outlet opening of the water mixing proportional valve according to the flow parameter corresponding to the water demand.

[0133] In this embodiment, the flow parameter is a parameter pre-set in each operation mode and used to control the water flow rate of the mixing terminal. The mixing proportional valve is a three-way valve, and its three interfaces are connected to the hot water inlet, the cold water inlet and the outlet to form a water outlet pipeline. The water outlet opening refers to the degree of opening of the mixing proportional valve, and the opening size determines the flow rate of water in the water outlet pipeline. In this step, the water outlet opening of the mixing proportional valve is adjusted according to the flow parameter of the water demand to control the water outlet flow.

[0134] As an optional implementation, after determining the water demand, the water mixing terminal obtains the flow parameter corresponding to the operation mode from the stored mode parameter library. For example, the flow parameter corresponding to the "comfortable bathing mode" is a larger flow, and the flow parameter corresponding to the "energy-saving mode" is a smaller flow. Then, the water mixing terminal calculates the appropriate water outlet opening value based on the correspondence between the flow parameter and the water outlet opening. Then, a control signal is sent to the water mixing proportional valve to adjust its water outlet opening to the calculated value, thereby realizing the control of the water outlet flow.

[0135] For example, the water demand is "comfortable bathing mode", and its corresponding flow parameter requires a larger flow rate. The water mixing terminal calculates that the water outlet opening of the water mixing proportional valve should be 80% based on the preset flow-opening relationship. Then, a control instruction is sent to the water mixing proportional valve to adjust its water outlet opening to 80%, so that the water mixing terminal can discharge water at a larger flow rate.

[0136] Step E30, collecting the water outlet temperature.

[0137] In this embodiment, the water outlet temperature refers to the actual temperature of the water flow at the water outlet of the mixing water terminal. The temperature detection module is set at the water outlet to collect the water outlet temperature in real time. In this step, the actual water temperature of the water outlet is obtained through the temperature detection module to provide data basis for subsequent determination of whether to perform cold water circulation action and other operations.

[0138] As an optional implementation, when the water mixing proportional valve adjusts the water outlet opening and water starts to flow out of the water outlet, the temperature detection module starts to work. The temperature sensor in the temperature detection module contacts the water flow, converts the detected water temperature into an electrical signal, and transmits the electrical signal to the water mixing terminal. After receiving the electrical signal, the water mixing terminal processes and converts it to obtain the actual temperature value of the water outlet.

[0139] For example, the thermistor sensor in the temperature detection module detects the temperature change of the water flow at the water outlet, converts the temperature change into a change in resistance value, and then converts it into an electrical signal. After the electrical signal is transmitted to the mixing water terminal, it undergoes analog-to-digital conversion and calibration, and the outlet temperature is 35°C.

[0140] Through the method in the above embodiment, after receiving the water outlet command, the mixing water terminal can reasonably adjust the water outlet flow according to the water demand and collect the water outlet temperature in real time, providing a basis for subsequent control operations and improving the accuracy of hot water supply and user experience.

[0141] Based on any of the above embodiments, the present application further provides embodiment 9. In this embodiment, after step S24, the following steps are included: Step E40: If the cold water circulation action is not performed, the adjustment parameters of the water mixing proportional valve are determined according to the set temperature and the water outlet temperature.

[0142] In this embodiment, the cold water circulation action refers to the operation initiated by the water mixing terminal to make the cold water in the hot water pipe flow back to the water heater through the circulation pipeline for reheating when the actual water outlet temperature is lower than the set temperature. The set temperature is the desired final water outlet temperature set by the user in the water mixing terminal. The water outlet temperature is the actual temperature of the water flow at the water outlet measured and fed back in real time by the temperature detection module. The adjustment parameters of the water mixing proportion valve are calculated based on the set temperature and the water outlet temperature, and are used to adjust the parameters of the opening of the water mixing proportion valve. By adjusting these parameters, the mixing ratio of hot water and cold water can be changed. In this step, when it is determined that the cold water circulation action does not need to be performed, the adjustment parameters of the water mixing proportion valve are determined based on the temperature data.

[0143] As an optional implementation, when the water mixing terminal determines that the cold water circulation action is not to be performed, the set temperature and the outlet temperature will be obtained. Then, the water mixing terminal calculates the adjustment parameters of the water mixing proportion valve based on the preset PID feedback adjustment and the two temperature values. For example, if the set temperature is higher than the outlet temperature, it means that the proportion of hot water needs to be increased, and the PID feedback adjustment will calculate the corresponding adjustment parameters to increase the opening of the hot water inlet; conversely, if the set temperature is lower than the outlet temperature, the proportion of cold water needs to be increased, and the PID feedback adjustment will calculate the corresponding adjustment parameters to increase the opening of the cold water inlet.

[0144] For example, the set temperature is 42°C and the water outlet temperature is 38°C. The mixing terminal adjusts according to the PID feedback and calculates that the opening of the hot water inlet needs to be increased by 20% and the opening of the cold water inlet needs to be reduced by 20%. These two opening change values ​​are the adjustment parameters of the mixing water proportional valve.

[0145] Step E40, adjusting the water mixing ratio valve according to the adjustment parameter to adjust the cold and hot water mixing ratio.

[0146] Glossary: ​​In this embodiment, the adjustment parameter is a calculated parameter used to adjust the opening of the water mixing ratio valve. The water mixing ratio valve is a valve that connects the hot water inlet, the cold water inlet and the outlet to form a water outlet pipeline. By adjusting its opening, the mixing ratio of hot water and cold water can be changed. In this step, the water mixing ratio valve is adjusted according to the adjustment parameter, thereby achieving control of the hot and cold water mixing ratio, so that the water temperature at the outlet is close to the set temperature.

[0147] As an optional implementation, the water mixing terminal converts the determined adjustment parameter into a control signal and sends it to the water mixing proportional valve. After receiving the control signal, the water mixing proportional valve adjusts the opening of the hot water inlet and the cold water inlet according to the signal content. For example, if the adjustment parameter requires increasing the opening of the hot water inlet, the water mixing proportional valve will increase the valve opening degree of the hot water inlet accordingly, and may reduce the opening of the cold water inlet, thereby increasing the proportion of hot water in the mixed water and raising the water temperature at the outlet.

[0148] For example, according to the previously calculated adjustment parameters, the water mixing terminal sends a signal to the water mixing proportional valve to increase the opening of the hot water inlet by 20% and reduce the opening of the cold water inlet by 20%. After receiving the signal, the water mixing proportional valve adjusts the valve opening to increase the hot water flow and reduce the cold water flow, thereby changing the hot and cold water mixing ratio and making the water temperature at the outlet gradually approach 42°C.

[0149] Through the method in the above embodiment, when there is no need to perform cold water circulation action, the mixing water terminal can accurately adjust the mixing water proportion valve according to the set temperature and the outlet temperature, change the ratio of cold and hot water mixing, ensure that the output water temperature meets user needs, and improve the stability and comfort of hot water supply.

[0150] To help understand the technical concept or technical principle of the control method of the water mixing terminal after the above embodiments are combined, please refer to Figure 4 , Figure 4 A brief flow chart of a control method for a water mixing terminal is provided, as follows: Exemplarily, when a user approaches the water mixing terminal, the identification module provided in the water mixing terminal starts to work. The identification module (such as a facial recognition camera) collects the user's user features (facial contours, proportions of facial features, etc.). The water mixing terminal compares the collected user features with the user feature templates pre-stored in the database, determines the memory mode that matches the user features, that is, the memory habit, and uses it as the water demand. If it is determined to execute the memory mode, the detection value of the temperature detection module is obtained to perform temperature detection. If it is determined that a cold water circulation needs to be executed, that is, a zero cold water function, based on the outlet temperature detected by the temperature, the water mixing terminal sends relevant data to the superheater through the communication module, including but not limited to the whole machine control instructions, to realize the whole machine linkage between the water mixing terminal and the water heater. During this period, the temperature detection module then performs a temperature detection action to realize the dynamic linkage between the water mixing terminal and the water heater.

[0151] For example, if the memory mode, i.e., the memory habit, is not used, the user can also operate through the display module set in the water mixing terminal. If the touch information he operates on the display module is to select a specific bathing function, temperature, flow rate and other setting parameters, the water mixing terminal will respond to these touch information, determine the setting parameters (the user clicks to set the temperature to 40°C and selects the comfortable bathing function), and determine the water demand based on these setting parameters and associate it with the current user's memory mode.

[0152] For example, if the user makes adjustments through the mechanical knob set in the mixing water terminal, such as rotating the mechanical knob to the gear position corresponding to the comfortable bathing mode, the mixing water terminal responds to the adjustment information of the mechanical knob, and determines that the water demand is for the comfortable bathing mode based on the gear position of the knob and the adjustment information.

[0153] Exemplarily, when a user approaches the water mixing terminal, the identification module provided in the water mixing terminal starts to work. The identification module (such as a facial recognition camera) collects the user features (facial contours, proportions of facial features, etc.) of the user. The water mixing terminal compares the collected user features with the user feature templates pre-stored in the database, determines the memory mode that matches the user features, that is, the memory habit, and uses it as the water demand. If it is determined to execute the memory mode, the detection value of the temperature detection module is obtained to perform temperature detection. If it is determined that the cold water circulation does not need to be performed based on the outlet temperature detected by the temperature, it is determined whether the trigger action of the adjustment component is received. If the trigger action is received, the water demand is determined based on the trigger action, and then the whole machine control instruction is generated based on the water demand. The water mixing terminal and the water heater are linked together according to the communication module to make the outlet temperature reach the set water temperature.

[0154] As an example, in response to the user's instruction to turn on the faucet, the water mixing terminal determines the water demand (comfortable bathing mode). The water mixing terminal obtains the flow parameter (large flow) corresponding to the comfortable bathing mode from the stored mode parameter library, calculates the appropriate water outlet opening value (assuming it is 70%) based on the corresponding relationship between the flow parameter and the water outlet opening of the water mixing proportional valve, and then sends a control signal to the water mixing proportional valve to adjust its water outlet opening to 70%. When the water flows out of the water outlet, the temperature detection module set at the water outlet starts to work and collects the water outlet temperature in real time. Assume that the collected water outlet temperature at this time is 32°C. The water mixing terminal compares the collected water outlet temperature of 32°C with the set temperature of 40°C corresponding to the water demand (comfortable bathing mode), finds that the actual temperature is lower than the set temperature, and determines that the cold water circulation action needs to be executed. The water mixing terminal sends an instruction to the circulation switch, and adjusts the opening of the circulation switch (assuming it is adjusted to 60%) according to the PID feedback adjustment and the difference between the current water temperature and the set temperature to control the opening of the circulation pipeline. At this time, the cold water in the hot water pipe flows back to the water heater through the circulation pipeline for heating. The water mixing terminal uses PID feedback adjustment to calculate the whole machine control parameters (such as a 25% increase in gas volume and a 20% increase in fan speed) based on the set temperature of 40°C and water demand (comfortable bathing mode), combined with factors such as ambient temperature, and then sends these parameters to the gas water heater. The water heater adjusts the combustion state based on these parameters, increases the combustion intensity, and quickly heats the water. As the cold water circulation proceeds, the outlet temperature gradually increases. The temperature detection module continuously monitors the outlet temperature. When the temperature reaches 40°C, the water mixing terminal determines again that the cold water circulation action does not need to be executed at this time. The water mixing terminal determines the adjustment parameters of the water mixing proportion valve based on the set temperature of 40°C and the current outlet temperature of 40°C (maintaining the current mixing ratio of hot water and cold water, that is, the opening of the water mixing proportion valve remains unchanged), and adjusts the water mixing proportion valve according to the adjustment parameters to maintain the current hot and cold water mixing ratio and ensure that the water temperature is stable at 40°C. During the bathing process, if the user clicks the health detection command on the display module, the display module transmits the command signal to the water mixing terminal. After receiving the command, the mixed water terminal calls the identification module (such as a wristband device with heart rate detection function connected to the mixed water terminal) to collect the user's user characteristics (heart rate data). Based on the collected user characteristics (heart rate data), the mixed water terminal calculates the user's health data (such as the normal range of heart rate) through model analysis and displays it on the display module, so that users can understand their own health status.

[0155] Through the above complete embodiment, the water mixing terminal can comprehensively use multiple functions to intelligently and efficiently control the hot water supply according to the user's operation and actual situation, providing users with a comfortable and convenient bathing experience.
