[0046] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0047] The water temperature control method of the water heater provided by the embodiments of the present application can be applied in an application environment as shown in Figure 1 The water heater 10 delivers hot water to a water use end required by a user through a water delivery pipeline 20. The water heater 10 includes a controller 11. When the controller 11 identifies that the water use mode of the water heater is a remote water use mode, the controller 11 acquires a user set temperature value and an actual temperature value of the water use end. The controller 11 compares the user set temperature value and the actual temperature value of the water use end. If the two values are not equal, the controller 11 acquires a water delivery distance between the water use end and the water heater. Based on the water delivery distance, the controller 11 acquires a water delivery heat dissipation temperature value. According to the water delivery heat dissipation temperature value and the user set temperature value, the controller 11 acquires a water heater operation temperature value. According to the water heater operation temperature value, the controller 11 controls the water heater to operate.

[0048] In an embodiment, as shown in Figure 2 A water temperature control method of a water heater is provided, including the following steps:

[0049] S100: If the water use mode of the water heater is a remote water use mode, acquiring a user set temperature value and an actual temperature value of a water use end.

[0050] The water use mode of the water heater is a mode in which the user starts the water heater to use hot water. The water use mode of the water heater can include, but is not limited to, a remote water use mode and a normal water use mode. The remote water use mode is a mode in which the water heater needs to be used in a remote situation. Before entering the normal water use mode, the heat dissipation of the water heater 10 in the remote situation can be determined by entering the remote water use mode, so that the user set temperature value and the actual temperature value of the water use end are close to each other in the normal water use mode.

[0051] The water use mode of the water heater can be determined by identifying the operation mode of the water heater. The water use mode of the water heater can be identified by analyzing the water heater adjustment (start) request to identify the water use mode of the water heater required by the user this time. For example, the water heater adjustment (start) request can be a request issued by the user, and the controller 11 responds to the user operation to obtain the corresponding water heater adjustment (start) request. The user operation can specifically include the user pressing / touching the start button, the user pressing / touching the mode adjustment button, and the like. Further, the user can also issue an adjustment instruction to the water heater through voice, gesture, etc. The controller 11 responds to the user operation to obtain the corresponding water heater adjustment request, and identifies the operation mode of the water heater required by the user, i.e., the operation mode of the water heater.

[0052] If the identified operation mode of the water heater is the remote water use mode, the user set temperature value and the water end actual temperature value are obtained. The user set temperature value is the temperature value that the user requires the water heater to heat the water to. When the water heater heats to reach the user set temperature value, the water heater stops heating the water inside to continue to heat, and the water heater only needs to heat and keep the water inside to maintain the user set temperature value. The user can adjust the user set temperature value of the water heater according to his / her own needs or different seasons. The user set temperature value can be obtained through the controller 11. The water end actual temperature value is the temperature value reached by the water outlet at the water end. The water end actual temperature value detected by the temperature detector can be directly obtained through the controller 11.

[0053] S200: If the user set temperature value is not equal to the water end actual temperature value, the water delivery distance between the water end and the water heater is obtained.

[0054] After obtaining the user set temperature value and the water end actual temperature value, the user set temperature value and the water end actual temperature value can be compared to determine whether the user set temperature value is equal to the water end actual temperature value. The controller 30 can compare the user set temperature value and the water end actual temperature value to obtain a comparison result.

[0055] If the user set temperature value is not equal to the water end actual temperature value, the heat dissipation of the water heater 10 at a long distance needs to be determined. The water delivery distance between the water end and the water heater can be obtained first. The water delivery distance between the water end and the water heater is used to represent the length of the water path between the water heater and the water end. The water delivery distance between the water end and the water heater can be calculated by the controller 11 or can be preset. The specific calculation method of the water delivery distance between the water end and the water heater is not limited in this embodiment.

[0056] S300: Based on the water delivery distance, the water delivery heat dissipation temperature value is obtained.

[0057] The water delivery heat loss temperature value is used to represent the temperature value lost during the process of hot water delivery from the outlet end of the water heater to the water use end. After the water delivery distance is obtained, the water delivery heat loss temperature value can be calculated by the controller 11. The specific calculation method of the water delivery heat loss temperature value in the embodiment is not limited.

[0058] In the embodiment of the application, when the water delivery heat loss temperature value is obtained, the remote water use mode can be exited. The exit mode can be active exit in response to the obtained water delivery heat loss temperature value, or can be a prompt message for actively pushing the remote water use mode based on the water delivery heat loss temperature value, and the remote water use mode is exited by obtaining the operation of the user. The specific exit mode is not limited. Further, when the remote water use mode is exited, the normal water use mode is entered.

[0059] S400: Obtain the water heater running temperature value according to the water delivery heat loss temperature value and the user set temperature value.

[0060] The water heater running temperature value is used to represent the set temperature value of the water heater in actual operation. When the water delivery heat loss temperature value and the user set temperature value are obtained, the user set temperature value can be corrected to obtain the water heater running temperature value. Specifically, the water heater running temperature value can be calculated by the controller 11 according to the water delivery heat loss temperature value and the user set temperature value. The specific calculation method of the water heater running temperature value in the embodiment is not limited.

[0061] It should be pointed out that the correction of the user set temperature value does not mean the correction of the user set temperature value, but an additional water heater running temperature value is obtained on the basis of the user set temperature value. For example, when the delivery heat loss temperature value is 5℃, the user set temperature value is 40℃, and the water heater running temperature value is 45℃.

[0062] S500: Control the water heater to run according to the water heater running temperature value.

[0063] When the water heater running temperature value is determined, the water heater can run under the control of the controller 11. The running of the water heater means that the water heater runs according to the running parameters, wherein the running parameters include the water heater running temperature value.

[0064] Therefore, the water temperature control method of the water heater can obtain the water delivery distance between the water delivery end and the water heater when the user-set temperature value and the actual temperature value of the water delivery end are not equal, and obtain the water delivery heat dissipation temperature value based on the water delivery distance, so as to determine the temperature value of the hot water dissipated at the water delivery distance. Further, the water heater operation temperature value is obtained according to the water delivery heat dissipation temperature value and the user-set temperature value, so that the actual temperature value of the water delivery end can be close to the user-set temperature value when the water heater operates according to the water heater operation temperature value, and the difference between the actual temperature value of the water delivery end and the user-set temperature value can be significantly reduced.

[0065] As shown in Figure 3 S300 includes, in one embodiment:

[0066] S320: obtaining an environment heat dissipation temperature value based on the water delivery distance.

[0067] The environment heat dissipation temperature value refers to the heat dissipation value of the hot water caused by the environmental factors related to the water delivery pipeline 20 of the water heater, which includes the structural size of the water delivery pipeline 20 itself, the structure of the wall where the water delivery pipeline 20 is located, the distance between the water delivery pipeline 20 and the cold water delivery pipeline 20, etc.

[0068] S340: identifying the current water use season and obtaining a seasonal heat dissipation temperature value based on the current water use season.

[0069] The current water use season refers to the season in which the area where the water heater is installed is currently in. For example, the water heater is installed in a family in Zhuhai, and Zhuhai is currently in spring. In some embodiments, the current water use season can be directly obtained and identified after the WIFI module is connected to the network. For example, the water heater is installed in a family in Zhuhai, the WIFI module is connected to the Internet, and the season of Zhuhai is directly obtained from the Internet to identify the current water use season. In other embodiments, the current water use season can also be identified by identifying the season information input by the user on the operation panel. Specifically, the current water use season is determined in response to the user's water use season selection setting operation. For example, four buttons of spring, summer, autumn and winter are designed on the operation panel to determine the current water use season by obtaining the user's clicking operation on the buttons. In other embodiments, a water use season selection prompt message can be pushed before responding to the user's water use season selection setting operation, for example, a water use season selection prompt message is pushed on the display panel to determine the current water use season by obtaining the user's clicking operation on the display panel.

[0070] After identifying the current water usage season, the controller 11 can obtain the seasonal heat dissipation temperature value based on the current water usage season. The seasonal heat dissipation temperature value refers to the amount of heat loss caused by the current water usage season factors related to the water supply pipe 20 of the water heater. For example, the controller 11 can obtain the seasonal heat dissipation temperature value based on the current water usage season and the preset relationship between the season and the seasonal heat dissipation temperature value. The seasonal heat dissipation temperature value corresponding to spring is 2 degrees Celsius.

[0071] S360: The water supply heat dissipation temperature value is obtained based on the ambient heat dissipation temperature value and the seasonal heat dissipation temperature value.

[0072] After obtaining the ambient heat dissipation temperature value and the seasonal heat dissipation temperature value, the water supply heat dissipation temperature value can be calculated by the controller 11. For example, the water supply heat dissipation temperature value can be obtained by summing the ambient heat dissipation temperature value and the seasonal heat dissipation temperature value.

[0073] By calculating the water supply temperature value based on both the ambient and seasonal heat dissipation temperatures, the heat dissipation problem caused by both environmental and seasonal factors is comprehensively considered. This results in a higher accuracy in calculating the water supply temperature value, making the user-set temperature value closer to the actual temperature value at the water end.

[0074] like Figure 4 As shown, in one embodiment, S320 includes: obtaining the ambient heat dissipation temperature value based on the water conveyance distance and through a preset distance-temperature function relationship.

[0075] The preset distance-temperature function is used to characterize the functional relationship between the water conveyance distance and the ambient heat dissipation temperature. The preset distance-temperature function can be pre-set or established based on historical data; there is no specific limitation.

[0076] By pre-setting a distance-temperature function relationship, the process of obtaining the ambient heat dissipation temperature value can be simplified, and the ambient heat dissipation temperature value can be made more accurate.

[0077] Furthermore, the preset distance-temperature function relationship is obtained in the following way:

[0078] Historical water conveyance distance data and historical environmental heat dissipation temperature data are obtained; based on the historical water conveyance distance data and historical environmental heat dissipation temperature data, simulation is performed to obtain the preset distance-temperature function relationship.

[0079] The historical water delivery distance data can refer to water delivery distance data of the water heater used by the user or the manufacturer at a historical time. The historical ambient heat dissipation temperature data can refer to ambient heat dissipation temperature data of the water heater used by the user or the manufacturer at a historical time, wherein the historical time can refer to a time before the current time. The way of obtaining the preset distance-temperature function relationship through simulation can be that the preset distance-temperature function relationship is obtained after the historical water delivery distance data and the historical ambient heat dissipation temperature data are input into a simulation software, wherein the simulation software can be MATLAB, etc.

[0080] It should be noted that MATLAB is well known to those skilled in the art, and for the sake of brevity, it will not be described in detail here.

[0081] Continuing to refer to Figure 4 In one embodiment, S200 includes:

[0082] S220: If the user set temperature value and the water end actual temperature value are not equal, obtaining the water outlet flow value of the water heater and the water outlet timing time;

[0083] The water outlet flow value of the water heater refers to the water flow value of the water outlet end of the water heater. The water outlet flow value can be obtained by the controller 11 after being collected by the water flow sensor arranged at the water outlet end. The water outlet timing time refers to the time obtained by timing the water outlet end of the water heater. The water outlet timing time can be obtained by the controller 11 after being collected by the timer arranged in the water heater.

[0084] S240: Based on the water outlet flow value of the water heater and the water outlet timing time, obtaining the water delivery distance between the water end and the water heater.

[0085] After obtaining the water outlet flow value of the water heater and the water outlet timing time, the water delivery distance between the water end and the water heater can be calculated by the controller 11.

[0086] The way of obtaining the water delivery distance between the water end and the water heater based on the water outlet flow value of the water heater and the water outlet timing time is simple, and since it is determined according to the actual operation process of the water heater, the obtained water delivery distance is more accurate.

[0087] In order to facilitate understanding of the water temperature control method of the water heater of the present application, a specific application example is provided below for illustration. As shown in Figure 5 The water temperature control method of the water heater of the present application includes the following steps in the specific application example:

[0088] 1. Identify the water use mode of the water heater. If the water use mode of the water heater is a remote water use mode, obtain the user set temperature value Tset and the water end actual temperature value Tout.

[0089] 2. Determine whether the user-set temperature value Tset and the actual water temperature value Tout are equal; if the user-set temperature value Tset and the actual water temperature value Tout are not equal, obtain the water flow rate value Vin of the water heater and the water flow timing time t; based on x = Vin × t, obtain the water delivery distance x between the water outlet and the water heater;

[0090] 3. Based on the water conveyance distance x, via T 环境 =f(x), to obtain the ambient heat dissipation temperature T. 环境 The f(x) is obtained by: acquiring historical water conveyance distance data and historical environmental heat dissipation temperature data; and using MATLAB simulation based on the historical water conveyance distance data and historical environmental heat dissipation temperature data to obtain f(x).

[0091] Specifically, as shown in Table 1 below, the historical water conveyance distance data and historical environmental heat dissipation temperature data are as follows:

[0092] Distance parameter x Corresponding T environment x1 T1 x2 T2 x3 T3 x4 T4 x5 T5 x6 T6 x7 T7

[0093] According to Table 1 above, the corresponding results can be obtained as follows: Figure 6 The graph shows the relationship between distance and heat dissipation temperature.

[0094] 4. Push a water usage season selection prompt message, respond to the user's water usage season selection settings, and confirm the current water usage season; obtain the seasonal heat dissipation temperature value T based on the current water usage season. 季节 ;

[0095] 5. According to T 散热 =T 季节 +T 环境 The water supply and heat dissipation temperature value T was obtained. 散热 ;

[0096] 6. Trun = Tset + T 散热 Obtain the water heater operating temperature value Trun;

[0097] 7. Control the operation of the water heater according to the operating temperature value Trun;

[0098] 8. Update the actual temperature value Tout at the water-using end in real time. When Tset = Tout, exit the remote water-using mode.

[0099] like Figure 7 As shown, in one embodiment, a water heater temperature control device is provided, the control device comprising:

[0100] The first acquisition module 100 is used to acquire the user-set temperature value and the actual temperature value at the water outlet when the water use mode of the water heater is the remote water use mode.

When the water heater operates according to the water heater operation temperature value, the actual temperature value of the water outlet and the user-set temperature value are close to each other, and the difference between the actual temperature value of the water outlet and the user-set temperature value is significantly reduced.

The modules can be embedded in or independent of a processor in a computer device in hardware form, or stored in a memory in the computer device in software form, so that the processor can call and execute the operations corresponding to the modules.

[0111] In addition, the application further provides a water heater, comprising a water heater body and a controller, wherein the controller is arranged on the water heater body.

Further, according to the water delivery heat dissipation temperature value and the user set temperature value, the water heater operation temperature value is obtained, and when the water heater operates according to the water heater operation temperature value, the actual temperature value of the water use end and the user set temperature value can be close to each other, and the difference between the actual temperature value of the water use end and the user set temperature value can be significantly reduced.
