[0066] With the continuous improvement of people's living standards, water heaters have become an important part of family life. It not only meets people's basic needs for daily hot water, but also relies on its small size and the characteristics of not being restricted by installation space, which makes it popular among users.

[0067] In the prior art, the heating time of a water heater is affected by the region, season and ambient temperature, and users have different requirements for water temperature when using the water heater in different seasons. However, some users are not sensitive to water temperature and will set the water heater to the highest temperature, which will not only lead to serious waste of water and electricity resources, but also pollute the environment, thus damaging the ecological environment; while other users will frequently adjust the water temperature, which may lead to insufficient hot water supply and waste of electricity resources, which will also affect the user experience.

[0068] Therefore, how to ensure that users have sufficient water consumption and save electricity to the maximum extent while achieving automatic adjustment of water temperature is a difficult problem that needs to be solved urgently.

[0069] In response to the above problems, the present application provides a method for determining the outlet water temperature. The method obtains the environmental information and basic parameters of the area where the smart home appliance is located to determine the outlet water temperature suitable for the user, thereby effectively avoiding the problem that some users set the water temperature of the smart home appliance to the highest temperature, resulting in the waste of water resources and electricity. At the same time, it also reduces the situation of insufficient hot water supply caused by other users frequently adjusting the water temperature, thereby improving the user experience. In addition, the method can also enable smart home appliances to use hot water resources more efficiently, reduce the waste of water and electricity resources, reduce pollution to the environment, and thus protect the ecological environment.

[0070] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0071] Figure 1 The method for determining the outlet water temperature provided in the embodiment of the present application is used to obtain the process Figure 1 The execution subject of this embodiment may be, for example, a processor of a smart home appliance. Figure 1 The method for determining the outlet water temperature provided in this embodiment includes:

[0072] S101: Obtaining environmental information of an area where a smart home appliance is located and basic parameters of the smart home appliance, wherein the basic parameters include water consumption, water inlet temperature, and water tank capacity.

[0073] Among them, environmental information refers to the current weather conditions in the area where the smart home appliance is located.

[0074] The environmental information of the area where the smart home appliance is located may be obtained from a user terminal or directly from a network, for example, and this application does not impose any restrictions on this.

[0075] The water consumption is used to indicate the amount of water consumed when the user corresponding to the smart home appliance uses the smart home appliance once. The user can be, for example, one person or all persons in the family corresponding to the smart home appliance.

[0076] The water inlet temperature is used to indicate the temperature of the water that enters the water tank of the smart home appliance through the water inlet pipe before the smart home appliance is used.

[0077] The water tank capacity is used to indicate the water capacity that the water tank of the smart home appliance can hold.

[0078] The basic parameters of the smart home appliance may be obtained, for example, from data in an application corresponding to the smart home appliance on a user terminal, or may be obtained from a data storage library of the smart home appliance.

[0079] In this step, the execution timing of obtaining the environment information of the area where the smart home appliance is located may be, for example, before the execution timing of obtaining the basic parameters of the smart home appliance, or after the execution timing of obtaining the basic parameters of the smart home appliance, or may be simultaneously obtaining the environment information of the area where the smart home appliance is located and the basic parameters of the smart home appliance. The specific execution timing is determined according to the actual situation.

[0080] S102: Determine a first outlet water temperature of the smart home appliance according to the environmental information.

[0081] Among them, the first outlet water temperature is the outlet water temperature suitable for the user corresponding to the area where the smart home appliance is located.

[0082] It is understandable that weather conditions vary in different regions. For example, the temperature in the south is higher and the temperature in the north is lower. When users are in environments with different temperatures, the temperatures they feel when in contact with the outside world are also different, and different perceived temperatures correspond to different water temperatures. For example: when the temperature felt by the user when in contact with the outside world is 20°C, the best water temperature for the user is 37°C, that is: when the water outlet temperature of the smart home appliance is 37°C at this time, the user experience is best. Therefore, the environmental information of the area where the smart home appliance is located can be obtained to accurately and quickly determine the water outlet temperature suitable for the user, thereby ensuring the accuracy of the water outlet temperature of the smart home appliance and improving the user experience.

[0083] The environmental information includes the weather conditions in the area where the smart home appliance is located. In this step, the outlet water temperature suitable for the user can be determined according to the weather conditions in the area where the smart home appliance is located.

[0084] For example, if the current weather condition in the area where the smart home appliance is located is sunny, 27°C, 36% humidity, southeast wind direction, and 4.2 m / s wind speed, the outlet water temperature suitable for the user is determined to be 41°C based on the current weather condition.

[0085] S103: Determine a second water outlet temperature of the smart home appliance according to the first water outlet temperature, the water consumption, the water inlet temperature and the water tank capacity.

[0086] Among them, the second water outlet temperature is the water temperature that users can use normally.

[0087] The water temperature that can be normally used by the user can be determined based on the water outlet temperature suitable for the user corresponding to the area where the smart home appliance is located, the amount of water consumed by the user corresponding to the smart home appliance when using the smart home appliance once, the water capacity that the water tank of the smart home appliance can hold, and the temperature of the water entering the water tank of the smart home appliance through the water inlet pipe before the smart home appliance is used.

[0088] It can be understood that when determining the water temperature that the user can use normally in this step, the water outlet temperature suitable for the user corresponding to the area where the smart home appliance is located is fully considered, so that the determined hot water temperature is more in line with user needs, thereby saving the user's time in manually adjusting the water temperature and improving the user's experience.

[0089] For example, a possible implementation method for obtaining the inlet water temperature is given here. Specifically, it is determined whether the application corresponding to the smart home appliance on the user terminal has obtained the location information of the smart home appliance; if so, the temperature of the water entering the water tank of the smart home appliance is obtained through the application corresponding to the smart home appliance on the user terminal; if not, the temperature of the water entering the water tank of the smart home appliance is obtained according to the inlet water temperature month comparison table.

[0090] The purpose of judging whether the application of the user terminal has obtained the location information of the smart home appliance is to determine whether the temperature of the water entering the water tank of the smart home appliance is obtained based on the location information of the smart home appliance.

[0091] If the application corresponding to the smart home appliance on the user terminal obtains the location information of the smart home appliance, it means that the smart home appliance can obtain the temperature of water entering the water tank of the smart home appliance based on the location information of the smart home appliance. At this time, the smart home appliance obtains the temperature of water entering the water tank of the smart home appliance based on the location information of the smart home appliance.

[0092] If the application corresponding to the smart home appliance on the user terminal does not obtain the location information of the smart home appliance, it means that the smart home appliance cannot obtain the temperature of the water entering the water tank of the smart home appliance based on the location information of the smart home appliance. At this time, the smart home appliance obtains the temperature of the water entering the water tank of the smart home appliance based on the water inlet temperature month comparison table.

[0093] The water inlet temperature month comparison table is used to indicate the different temperatures of water entering the smart home appliance water tank corresponding to different months. The water inlet temperature comparison table may include, for example: different months, and the different temperatures of water entering the smart home appliance water tank corresponding to different months. Table 1 is a schematic table of the water inlet temperature month comparison table shown in this embodiment. Table 1

[0094] As described in Table 1, the corresponding inlet water temperature in January is 7°C; the corresponding inlet water temperature in February is 8°C; the corresponding inlet water temperature in March is 9°C; the corresponding inlet water temperature in April is 13°C; the corresponding inlet water temperature in May is 15°C; the corresponding inlet water temperature in June is 19°C; the corresponding inlet water temperature in July is 20°C; the corresponding inlet water temperature in August is 21°C; the corresponding inlet water temperature in September is 19°C; the corresponding inlet water temperature in October is 15°C; and the corresponding inlet water temperature in December is 8°C.

[0095] S104: Setting the second water outlet temperature as the water outlet temperature of the smart home appliance.

[0096] Among them, after determining the water temperature that the user can normally use, the smart home appliances can be controlled to set the water temperature that the user can normally use as the water outlet temperature of the smart home appliances, so as to avoid some users setting the water temperature of the water heater to the highest temperature, resulting in waste of water resources and electricity. At the same time, it also reduces the situation of insufficient hot water supply caused by other users frequently adjusting the water temperature, thereby improving the user experience.

[0097] The method for determining the outlet water temperature provided in this embodiment determines the outlet water temperature suitable for the user by acquiring the environmental information and basic parameters of the area where the smart home appliance is located, and then determines the water temperature that the user can normally use according to the outlet water temperature suitable for the user, the user's water consumption, the water inlet temperature of the smart home appliance, and the water tank capacity of the smart home appliance, and sets the water temperature as the output temperature of the smart home appliance. This method not only enables the smart home appliance to automatically adjust the water temperature, but also ensures sufficient water consumption for the user, saves electricity to the maximum extent, and improves the user's experience.

[0098] Figure 2 The process of the method for determining the outlet water temperature provided in the embodiment of the present application is as follows Figure 2 The execution subject of this embodiment may be, for example, a processor of a smart home appliance. Figure 2 As shown, this embodiment is Figure 1 Based on the embodiment, the method for determining the outlet water temperature is described in detail. The method for determining the outlet water temperature provided in this embodiment includes:

[0099] S201: Obtain historical usage time periods of smart home appliances in historical data.

[0100] The historical data may include, for example, the time when the smart home appliance was in operation. The historical usage period of the smart home appliance may be, for example, the period when the user frequently used the smart home appliance.

[0101] The historical data may be obtained, for example, from a data storage repository of the smart home appliance, or may be obtained through an application corresponding to the smart home appliance on a user terminal.

[0102] The purpose of this step is to quickly obtain the time period when the user frequently uses the smart home appliance from the historical data, thereby improving the efficiency of determining the time period when the user frequently uses the smart home appliance. It can be understood that the execution time of obtaining the historical use time period of the smart home appliance is after obtaining the historical data.

[0103] It is understandable that after the historical data of the smart home appliance is obtained, the historical usage time period of the smart home appliance can be found from the historical data of the smart home appliance, thereby determining the time period when the user frequently uses the smart home appliance.

[0104] S202: Determine, based on the historical usage period, environmental information of a period corresponding to the historical usage period in the area where the smart home appliance is located.

[0105] Among them, the current environment information corresponding to the area where the smart home appliance is located and the time period when the user often uses the smart home appliance can be determined according to the time when the user often uses the smart home appliance.

[0106] It can be understood that when determining the current environmental information of the area where the smart appliances are located, this step fully considers the time when users frequently use the smart appliances, so that the determined environmental information matches the user's usage needs, saving the user's time in choosing to use smart appliances and improving the user's usage experience.

[0107] For example, the user usually uses the smart appliance at 9:30 pm, so the smart appliance obtains the current environmental information of the area where the smart appliance is located as sunny, 25°C, 46% humidity, east wind direction and 3.6 m / s wind speed.

[0108] S203: Obtain the number of family members, water tank capacity, and water inlet temperature corresponding to the smart home appliance through an application corresponding to the smart home appliance in the user terminal.

[0109] Among them, the number of family members is used to indicate the number of family members of the family corresponding to the smart home appliance.

[0110] It can be understood that the purpose of obtaining the number of family members, water tank capacity and inlet water temperature of the family corresponding to the smart home appliance is to instruct the smart home appliance to determine the user's family water consumption through the obtained family member population, and then instruct the smart home appliance to determine the outlet water temperature that the smart home appliance needs to heat based on the family water consumption, water tank capacity and inlet water temperature.

[0111] S204: Determine the water consumption of the smart home appliance according to the number of the family members.

[0112] Among them, the amount of water consumed by the user corresponding to the smart home appliance when using the smart home appliance for a single time can be determined according to the number of family members of the family corresponding to the smart home appliance.

[0113] It is understandable that there is a correlation between the number of family members and the amount of water consumed by the user corresponding to the smart home appliance when the smart home appliance is used once. After the number of family members is determined, the amount of water consumed by the user matching the number of family members when the smart home appliance is used once can be determined based on the number of family members.

[0114] Optionally, the water consumption of smart home appliances can be determined using the following formula: M1=N×A

[0115] Wherein, M1 is the total water consumption of the family members (L), N is the number of family members, A is the amount of water used by each family member at a time (L), and A is an integer greater than 0.

[0116] For example, the user's family size is 3 people, A is 20L, and the household water consumption determined by the above formula is 60L.

[0117] S205: The environmental information includes: the outdoor temperature, humidity and wind speed of the area where the smart home appliance is located; and determining the perceived temperature corresponding to the area where the smart home appliance is located according to the outdoor temperature, the humidity and the wind speed.

[0118] Among them, the perceived temperature is the temperature that the user can feel in the area where the smart home appliance is located.

[0119] Factors that affect the perceived temperature may include, for example, outdoor temperature, humidity, and wind speed. It is understandable that if the perceived temperature is higher than the outdoor temperature, it indicates that the above factors have a warming effect on the user. If the perceived temperature is not higher than the outdoor temperature, it indicates that the above factors have a cooling effect on the user. Specifically, the wind speed can affect the amount of air that can come into contact with the user's surface. When the wind speed increases, the amount of air in contact with the user will increase, that is, the heat brought in or the heat taken away will increase accordingly. When the air humidity increases, the user's perceived temperature will also increase.

[0120] It can be understood that the temperature felt by the user in the area where the smart home appliance is located can be determined based on the outdoor temperature, humidity and wind speed of the area where the smart home appliance is located.

[0121] In this step, the current outdoor temperature, humidity and wind speed of the area where the smart home appliance is located can be obtained first, and then the perceived temperature of the area where the smart home appliance is located can be determined based on the outdoor temperature, humidity and wind speed.

[0122] Optionally, determining the perceived temperature corresponding to the area where the smart home appliance is located according to the outdoor temperature, the humidity and the wind speed includes:

[0123] The following formula is used to determine the body temperature corresponding to the area where the smart home appliance is located: AT = 1.07T + 0.2e-0.65V-2.7;

[0124] Wherein, AT is the perceived temperature (°C); T is the outdoor temperature (°C); e is the water vapor pressure (hPa); V is the wind speed (m / sec); RH is the humidity (%), and exp is the natural exponential function.

[0125] From the above formula, we can know that the user's perceived temperature is affected by the outdoor temperature, humidity and wind speed. Among them, when the outdoor temperature in the current environmental information of the area where the smart home appliance is located is higher, the user's perceived temperature is also higher; when the humidity in the current environmental information of the area where the smart home appliance is located is lower and the wind speed is higher, the user's perceived temperature is lower. Among them, the most comfortable outdoor temperature for the human body is 18-23℃ and the humidity is 45%-65%RH.

[0126] For example, the outdoor temperature in the area where the smart home appliance is located is 30°C, the humidity is 60%, and the wind speed is 10km / h. The specific process of the smart home appliance determining the perceived temperature is:

[0127] First determine the water vapor pressure e: e≈31.24(hPa)

[0128] Then determine the wind speed V: V=10÷3.6≈2.78(m / sec)

[0129] Finally determine the body temperature AT: AT=1.07×30+0.2×31.24-0.65×2.78-2.7≈33.9(℃)

[0130] S206: Determine a first outlet water temperature according to the perceived temperature.

[0131] Among them, the water outlet temperature suitable for the user corresponding to the area where the smart home appliance is located can be determined according to the user's body temperature in the area where the smart home appliance is located.

[0132] It is understandable that different body-felt temperatures correspond to different outlet water temperatures. When the user's body-felt temperature in the area where the smart home appliance is located is high, the outlet water temperature suitable for the user is determined to be low; when the user's body-felt temperature in the area where the smart home appliance is located is low, the outlet water temperature suitable for the user is determined to be high.

[0133] Exemplarily, a specific implementation method for determining the first outlet water temperature is given below, for example, which may be: obtaining a comparison relationship table between body sensible temperature and the first outlet water temperature; and determining the first outlet water temperature according to the body sensible temperature.

[0134] Among them, the comparison relationship table of the sensible temperature AT and the first outlet water temperature T is used to indicate that different sensible temperatures in different environments in the historical data and the outlet water temperatures corresponding to different sensible temperatures in different environments are uniformly summarized and sorted to establish a one-to-one correspondence.

[0135] The comparison table of the sensible temperature and the first outlet water temperature may include, for example, different sensible temperatures in different environments and the first outlet water temperatures corresponding to the different sensible temperatures in different environments. Table 2 is a schematic table of the comparison table of the sensible temperature AT and the first outlet water temperature T shown in this embodiment. Body temperature AT(℃) First outlet water temperature T(℃) AT ≥ 38℃ T＝33℃ 33℃≤AT<38℃ T＝34℃ 28℃≤AT<33℃ T＝35℃ 23℃≤AT<28℃ T＝36℃ 15℃≤AT<23℃ T＝37℃ 8℃≤AT<15℃ T＝38℃ 2℃≤AT<8℃ T＝39℃ -4℃≤AT<2℃ T＝40℃ AT<-4℃ T＝41℃ Table 2

[0136] As described in Table 2, when the perceived temperature AT in the historical data is greater than or equal to 38°C, the corresponding first outlet water temperature T is 33°C; when the perceived temperature AT in the historical data is less than 38°C and greater than or equal to 33°C, the corresponding first outlet water temperature T is 34°C; when the perceived temperature AT in the historical data is less than 33°C and greater than or equal to 28°C, the corresponding first outlet water temperature T is 35°C.

[0137] The purpose of obtaining the comparison table of the body-felt temperature AT and the first outlet water temperature T in this step is to quickly match the outlet water temperature that matches the user's body-felt temperature from historical data, thereby improving the efficiency of determination.

[0138] It can be understood that the comparison relationship table established based on historical data is based on facts and is obtained from historical data, and the comparison relationship table is updated in real time so that the body temperature and the outlet water temperature corresponding to the body temperature can be updated at any time.

[0139] For example, the user's body temperature in the current environment is 33.9° C. By querying the body temperature and the first outlet water temperature comparison table, it can be determined that the outlet water temperature suitable for the user is 34° C.

[0140] S207: Determine the amount of heat absorbed by the smart home appliance during a single use according to the first water outlet temperature, the water inlet temperature, and the water consumption.

[0141] The heat, for example, can be when the smart home appliance is in operation, the smart home appliance absorbs the heat of its surrounding environment and transfers the absorbed heat to the water entering the water tank of the smart home appliance, so that the water entering the water tank of the smart home appliance obtains heat. Absorbing heat means that when the smart home appliance is in operation, the water entering the water tank of the smart home appliance absorbs the heat released by the smart home appliance. Releasing heat means that when the smart home appliance is in operation, the smart home appliance absorbs the heat of the area where it is located and releases the absorbed heat.

[0142] Here, the process of heat transfer is explained by taking an air-energy water heater as an example. The air-energy water heater adopts the reverse Carnot principle, that is, the heat pump absorption principle. The specific process is as follows: the compressor sucks in the low-pressure gaseous refrigerant, converts it into a high-temperature and high-pressure gas, and pushes it into the condenser (i.e., the water tank heat exchange coil). Under the action of the throttle valve, the high-temperature and high-pressure gas is cooled from gas to liquid in the condenser, while releasing a large amount of energy. The released energy enters the water tank and heats up the water. The refrigerant that releases energy and becomes liquid flows into the evaporator (i.e., the air heat exchanger) through the throttle valve, and the pressure drops instantly. The liquid refrigerant evaporates into gas again under a low-pressure environment, absorbing a large amount of heat at this time. The low-pressure refrigerant that absorbs heat and becomes gaseous is sucked into the compressor and enters the next cycle. It can be understood that the air-energy water heater sucks in outdoor air through a fan, absorbs heat through the refrigerant in the evaporator, evaporates the refrigerant and compresses the steam generated after evaporation, and then releases the high-temperature and high-pressure refrigerant gas into the pipe in the water tank, thereby heating the water.

[0143] The amount of heat absorbed by a smart home appliance during a single use can be determined based on the water outlet temperature suitable for the user, the amount of water consumed by the user corresponding to the smart home appliance during a single use of the smart home appliance, and the temperature of water entering the water tank of the smart home appliance through the water inlet pipe before the smart home appliance is used.

[0144] Optionally, the following formula can be used to determine the amount of heat absorbed by the smart home appliance during a single use: Q 吸 =C 水 M1(T-T1)

[0145] Among them, Q 吸 The heat absorbed by the smart home appliance during a single use; C 水 The specific heat capacity of water is 4.2×10 3 J; M1 is the amount of water consumed by the corresponding user of the smart home appliance when using the smart home appliance once; T is the water outlet temperature suitable for the user corresponding to the area where the smart home appliance is located; T1 is the temperature of the water entering the water tank of the smart home appliance through the water inlet pipe before the smart home appliance is used.

[0146] Specific heat capacity is the amount of heat absorbed (or released) when the temperature of a substance per unit mass rises (or falls) by 1°C. It is represented by the symbol c and its unit is joule per kilogram Celsius. The symbol is J / (kg·°C). Specific heat capacity is a physical quantity that specifically represents the ability of an object to absorb or release heat. The physical meaning of the specific heat capacity of water is that when the temperature of 1 kg of water rises (or falls) by 1°C, the amount of heat absorbed (or released) is 4.2×10J.

[0147] For example, if the outlet water temperature is 34°C, the inlet water temperature is 10°C, and the water consumption of the user's family is 60L, then it can be determined that the heat absorbed by the smart home appliance during a single use is 6.05×10 6 J / KgK.

[0148] S208: Determine a second water outlet temperature of the smart home appliance according to the absorbed heat, the water tank capacity and the first water outlet temperature.

[0149] Among them, the water temperature that the user can use normally can be determined based on the amount of heat absorbed by the smart home appliance during a single use, the water capacity that the water tank of the smart home appliance can hold, and the water outlet temperature suitable for the user corresponding to the area where the smart home appliance is located. That is, the amount of heat released by the smart home appliance during a single use can be determined.

[0150] In this step, since the heat absorbed by the smart home appliance during a single use and the heat released by the smart home appliance during a single use can be equal without considering the heat loss, the heat released by the smart home appliance during a single use can be determined according to the heat absorbed by the smart home appliance during a single use, the water capacity of the water tank of the smart home appliance, and the water outlet temperature suitable for the user corresponding to the area where the smart home appliance is located.

[0151] It is understandable that the only condition for heat transfer to occur is the existence of a temperature difference, which has nothing to do with the state of the objects in the smart home appliance or whether the objects in the smart home appliance are in contact. The result of heat transfer is that the temperature difference disappears, that is, different parts of the object where heat transfer occurs reach the same temperature. The essence of heat transfer is the process of transferring internal energy from a high-temperature object to a low-temperature object. The specific process is that during the heat transfer process, the substance does not migrate, but the high-temperature object releases heat, the temperature decreases, the internal energy decreases, and the low-temperature object absorbs heat, the temperature increases, and the internal energy increases.

[0152] Here we continue to use the air energy water heater as an example for explanation. Without considering the heat loss, the air energy water heater absorbs the heat of its surrounding environment, and after heat transfer with the water entering the water tank of the air energy water heater, the heat released by the air energy water heater after absorbing the surrounding environment is equal to the heat absorbed by the water entering the water tank of the air energy water heater, that is: Q 放 =Q 吸 .

[0153] Optionally, use the following formula to determine the water temperature that the user can normally use: Q 放 =C 水 M2(T2-T)

[0154] Among them, Q 放 The heat released by smart home appliances during a single use; C 水 The specific heat capacity of water is 4.2×10 3 J; M2 is the water capacity that the water tank of the smart home appliance can hold; T is the water outlet temperature suitable for users in the area where the smart home appliance is located; T2 is the water temperature that users can use normally.

[0155] For example, the heat absorbed by a smart home appliance during a single use is 6.05×10 6 J / KgK, the water tank capacity is 150L, ​​because in the ideal case where heat loss is not taken into account, Q 放 =Q 吸 , that is: C 水 M2(T2-T)=C 水 M1(T-T1), through calculation, the temperature of T2 is 43.3°C. Therefore, it can be determined that the output temperature of the smart home appliance is 43.3°C.

[0156] Optionally, after determining the second water outlet temperature of the smart home appliance based on the first water outlet temperature, the water consumption, the water inlet temperature and the water tank capacity, the method also includes: obtaining the third water outlet temperature of the smart home appliance; determining whether the second water outlet temperature is lower than the third water outlet temperature; if so, setting the second water outlet temperature as the water outlet temperature of the smart home appliance; if not, sending a prompt message to the user terminal to remind the user to select the working mode of the smart home appliance.

[0157] Among them, the third water outlet temperature is used to indicate the upper limit of the water outlet temperature that can be set by the smart home appliance.

[0158] The purpose of judging whether the second outlet water temperature is lower than the third outlet water temperature is to determine whether the second outlet water temperature can meet the user's usage requirements.

[0159] If the second water outlet temperature is lower than the third water outlet temperature, it indicates that the second water outlet temperature is lower than the upper limit value of the water outlet temperature that can be set for the smart home appliance, that is, the second temperature can meet the user's usage requirements. At this time, the second water outlet temperature is set as the water outlet temperature of the smart home appliance; if the second water outlet temperature is not lower than the third water outlet temperature, it indicates that the second water outlet temperature is not lower than the upper limit value of the water outlet temperature that can be set for the smart home appliance, that is, the second temperature cannot meet the user's usage requirements. At this time, a prompt message is sent to the user terminal.

[0160] The method of sending the prompt information to the user terminal may be, for example, sending the prompt information to the user through an application corresponding to the smart home appliance installed on the user terminal, or sending the prompt information to the user through a text message or a newsletter, etc. This application does not impose any special restrictions on this.

[0161] For example, the second water outlet temperature is 41° C., and the third water outlet temperature is 45° C., so the smart home appliance can set 41° C. as the water outlet temperature of the smart home appliance.

[0162] S209: Setting the second water outlet temperature as the water outlet temperature of the smart home appliance.

[0163] Step S209 is similar to the above step S104 and will not be described again.

[0164] The method for determining the outlet water temperature provided in this embodiment determines the environmental information related to the historical usage period by obtaining the historical usage period of the smart home appliance; determines the water consumption of the user using the smart home appliance by obtaining the number of family members corresponding to the smart home appliance; determines the user's body temperature corresponding to the area where the smart home appliance is located by obtaining the outdoor temperature, humidity and wind speed corresponding to the area where the smart home appliance is located, and then determines the outlet water temperature suitable for the user based on the body temperature; determines the output temperature of the smart home appliance based on the outlet water temperature, water tank capacity, water inlet temperature and water consumption suitable for the user. This method avoids the problem of some users setting the water temperature of the smart home appliance to the highest temperature, resulting in waste of water resources and electricity, and also reduces the situation of insufficient hot water supply caused by other users frequently adjusting the water temperature, thereby improving the user's experience.
