[0002] A heat pump water heater is a highly efficient heat energy lifting and transfer device that works based on the reverse Carnot cycle. It can use a small amount of electricity as power and a refrigerant as a carrier to continuously absorb low-grade heat energy in the air and convert it into usable high-grade heat energy.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0077] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any person skilled in the art to implement and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the invention can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0078] First, the terms involved in this application are explained:

[0079] Heat pump water heater: a device that uses heat pump technology to heat water. A heat pump is a device that can transfer low-temperature heat energy to a high-temperature area. It uses components such as a compressor, evaporator, condenser, and expansion valve to achieve the transfer of heat energy. The working principle of a heat pump water heater is to absorb heat energy from the environment through the refrigerant in the evaporator, causing it to evaporate into gas. Then, the gas is compressed by the compressor to increase its temperature. Next, the high-temperature and high-pressure gas passes through the condenser, releasing heat to the water, causing the water temperature to rise. Finally, the refrigerant is depressurized by the expansion valve, becoming a low-temperature and low-pressure liquid, and re-enters the evaporator cycle.

[0080] The embodiments of the present application provide a water heater control method, device, electronic device, and computer-readable storage medium. Specifically, the embodiments of the present application provide a water heater control device applicable to the water heater control method, the water heater control device includes a water heater and a main control device of the water heater, and the water heater is mainly a heat pump water heater or other device that uses electrical energy and thermal energy in the environment to produce hot water.

[0081] In the prior art, in order to maintain the hot water temperature preset by the user during operation, the water heater will continuously use electrical energy to produce hot water and store it in a water tank.

[0082] For example, after the water heater is started, it monitors the temperature of the hot water stored in the water tank in real time. When the temperature is lower than the temperature preset by the user, it will use electrical energy to heat the hot water in the water tank in time until the water temperature reaches the temperature preset by the user.

[0083] However, the existing water heater control method monitors the water temperature in real time and needs to heat the water in time when the water temperature does not reach the set value, which causes great energy waste. In addition, the user's demand for hot water is far less than the heating time of the water heater, resulting in the water heater heating operation being ineffective for a long period of time every day.

[0084] Therefore, the water heater control method in the prior art has the problem of energy waste.

[0085] The embodiment of the present application provides a water heater control method, device, electronic device and computer-readable storage medium. The method adopts the following technical solutions: obtaining first temperature information and second temperature information, wherein the first temperature information is the predicted temperature change of the environment where the water heater is located in the first time period, and the second temperature information is the temperature of the hot water in the current water heater; determining the expected water use information based on the historical water use information, wherein the historical water use information is used to characterize the water use situation in the second time period before the current time, and the expected water use information includes the expected water use time and the expected water use temperature; and determining the target heating time based on the first temperature information, the second temperature information and the expected water use information.

[0086] In summary, the water heater control method in the embodiment of the present application can determine the target heating time of the water heater according to the changes in ambient temperature and the user's historical water usage information, and effectively produce hot water during the target heating time, thereby achieving the technical effect of reducing the energy consumption of the water heater.

[0087] It should be noted that the order of description of the following embodiments is not intended to limit the priority order of the embodiments.

[0089] In the embodiment of the present application, the water heater 100 includes but is not limited to a heat pump water heater, an electric water heater, a gas water heater, a solar water heater, a multi-energy water heater, etc.

[0090] Those skilled in the art will understand that Figure 1 The application environment shown in the figure is only one application scenario of the present application solution and does not constitute a limitation on the application scenario of the present application solution. Other application environments may also include Figure 1 More or less water heaters as shown in Figure 1 Only one water heater is shown, and the specific details are not limited here.

[0091] In addition, if Figure 1 As shown, the main control device 200 may include any hardware device capable of data processing and instruction sending, such as a CPU or a single-chip microcomputer embedded in the water heater, and the specific details are not limited here.

[0092] It should be noted that Figure 1 The scene diagram of the water heater control system shown is only an example. The water heater control system and scene described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. A person of ordinary skill in the art can know that with the evolution of the water heater control system and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0093] For details, please refer to Figure 2 , Figure 2 : is a schematic diagram of a scenario in which a water heater according to an embodiment of the present application executes the water heater control method, wherein the specific execution process of the water heater executing the water heater control method is as follows:

[0094] S201: Acquire first temperature information, and acquire second temperature information.

[0095] In the embodiment of the present application, the first temperature information is the predicted temperature change of the environment in which the water heater is located in a first period of time, and the second temperature information is the temperature of the hot water in the current water heater.

[0096] Optionally, the first temperature information may be the temperature change of the outdoor temperature within the first time period after the current moment predicted based on historical temperature information collected by a temperature sensor installed outdoors; the first temperature information may also be the temperature change of the area where the water heater is located within the first time period after the current moment obtained by the water heater through the networking module.

[0097] It should be noted that the method for collecting the first temperature information is not specifically limited in the embodiment of the present application; the temperature change of the environment in which the water heater is located can be the temperature change of the environment in the area where the water heater is installed, and the scope of the area can be modified or adjusted according to the actual situation, for example: when collecting the temperature through the outdoor temperature sensor, the water heater can be used as the center of the circle to predict the ambient temperature change within a preset distance; when obtaining the temperature through the networking module, the ambient temperature change can be predicted according to the area divided by the weather forecast. The first duration can be set to 24 hours, or it can be set to other time lengths, which is not specifically limited in the embodiment of the present application.

[0098] Optionally, the second temperature information may be the hot water temperature at the current moment collected by a temperature sensor installed in the water tank of the water heater; the hot water temperature in the water tank of the water heater may also be collected by other means.

[0099] In the embodiment of the present application, the time required for heating can be obtained based on the first temperature information and the second temperature information obtained, combined with the preset temperature set by the user (or the preset temperature obtained by analyzing the user's historical water usage information), and then the time to start heating, i.e., the target heating time, can be determined.

[0100] S202: Determine estimated water usage information based on historical water usage information.

[0101] In the embodiment of the present application, the historical water use information is used to characterize the water use situation within a second period of time before the current time, and the expected water use information includes the expected water use time and the expected water use temperature.

[0102] Optionally, the water heater will record the user's water usage data as historical water usage information when the user uses hot water, which may include: water usage time, water temperature changes, water temperature, water usage, water heater working mode when using water and other information.

[0103] As an optional embodiment, based on the collected historical water use information, the possible water use time and water use temperature of the user after the current moment are determined to obtain the estimated water use information.

[0104] It should be noted that the second time period can be set to any time length and is not specifically limited in the embodiments of the present application. In order to make the estimated water use information obtained by analysis more accurate, the second time period can be set to one month, that is, the historical water use data of the user in the past month is collected, and the possible estimated water use information after the user's current time (for example: within 24 hours after the current time) is analyzed.

[0105] Optionally, the water heater control method provided in the embodiment of the present application also includes: determining the working mode of the water heater within a third time period based on historical water use information, and determining the water temperature change of the water heater within the third time period, the third time period being a time period within the second time period; determining the expected water use time based on the working mode and the water temperature change.

[0106] In the embodiment of the present application, the third time period is the time period when the user uses hot water. For example, if the user uses hot water between 8:00-8:10 in the morning, the third time period is the time period between 8:00-8:10. The time period can be a time period of other times or a time period of any length.

[0107] Optionally, the estimated water usage information is obtained by analyzing the historical water usage information of multiple third time periods within the second time period, including the working mode of the water heater within the third time period and the water temperature change of the water heater within the third time period. For example, the estimated water usage time of the user is determined based on the daily hot water usage of the user within a month.

[0108] Optionally, the water heater control method provided in the embodiment of the present application also includes: when the working mode is a heating mode, if the water temperature change indicated by the water temperature change situation is greater than a preset change, then the time period corresponding to the third time length is determined as the expected water use time; when the working mode is a non-heating mode, if the water temperature indicated by the water temperature change situation has changed, then the time period corresponding to the third time length is determined as the expected water use time.

[0109] In the present application embodiment, Figure 3 The schematic diagram of the process flow for determining the estimated water use time shown in the figure, according to the user's historical water use information, determines whether the user turns on the electric heating or heat pump when using hot water, that is, the working mode of the water heater is heating mode or non-heating mode; when the working mode is heating mode, if the hot water temperature drops by 2 degrees Celsius (water temperature change) within 10 minutes (the third time length), the time period corresponding to the 10 minutes is determined to be the estimated water use time, and is included in the water use time point. Optionally, when the working mode is heating mode, if the hot water temperature drops by 3 degrees Celsius (water temperature change) within 15 minutes (the third time length), the time period corresponding to the 15 minutes can also be determined to be the estimated water use time, and is included in the water use time point. Optionally, when the working mode is non-heat mode, if the current hot water temperature is less than the hot water temperature 15 minutes (the third time length) ago, the time period corresponding to the 15 minutes is determined to be the estimated water use time, and is included in the water use time point.

[0110] It should be noted that the third time length can be the actual water usage time of the user, or it can be one or more time lengths set in advance. Different time lengths can correspond to different water temperature changes (that is, the preset change can be set according to actual usage).

[0111] Optionally, according to the occurrence frequencies of time periods corresponding to multiple third time periods within the second time period, a time period with a higher occurrence frequency may be selected as the user's estimated water usage time.

[0112] Optionally, the water usage temperatures of the users in multiple third time periods within the second time period may be counted to determine the expected water usage temperature of the users, so that the water heater can subsequently heat the water according to the expected water usage temperature.

[0113] S203: Determine the target heating time according to the first temperature information, the second temperature information and the estimated water usage information.

[0114] In the embodiment of the present application, after the main control device of the water heater obtains the user's expected water usage information, it determines the target heating time, that is, the time to start heating, in combination with the obtained first temperature information and second temperature information.

[0115] Optionally, the water heater obtains the ambient temperature data for 24 hours after the current moment, and then calculates the time required for heating by 5°C based on the current water tank temperature and the laboratory ambient temperature and water tank temperature data curve, and then compares it with the previously determined user's expected water use time and expected water temperature to obtain a suitable economical and energy-saving heating start time, and heats at this time, thereby achieving the purpose of energy saving.

[0116] Optionally, the water heater control method provided in the embodiment of the present application also includes: determining a first temperature value of the environment in which the water heater is located based on the first temperature information, the first temperature value being the temperature of the environment in which the water heater is currently located; determining a first heating time based on the expected water use temperature, the first temperature value and the second temperature information; and determining a target heating time based on the first heating time and the expected water use time.

[0117] In the present application embodiment, Figure 4 The target heating time determination process diagram shown in the figure determines the first temperature value of the environment in which the current water heater is located based on the first temperature information, and determines the first heating time (which can be calculated in combination with the temperature data curve or other algorithms) for heating from the current water temperature to the expected water use temperature under the current ambient temperature based on the expected water use temperature and the first temperature value as well as the hot water temperature in the current water heater. After obtaining the first heating time, the target heating time is determined based on the first heating time and the expected water use time.

[0118] Optionally, the water heater control method provided in the embodiment of the present application also includes: if the first heating time is greater than or equal to the expected water usage time, then determining the target heating time as the current time; if the first heating time is less than the expected water usage time, then determining the second temperature value according to the first temperature information, and determining the target heating time according to the second temperature value, the second temperature information and the expected water usage information, the second temperature value being the highest temperature value within the first time period.

[0119] Specifically, it is determined whether the first heating time is greater than the expected water use time. If so, the target heating time is determined to be the current time, and the water heater starts heating immediately and stops after heating to the expected water use temperature.
