[0025] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0026] Please refer to Figure 1 , Figure 1is a flowchart of an electric water heater control method provided by an embodiment of the present application. The electric water heater control method is used to analyze a user's water usage habit according to historical usage data of an electric water heater to obtain control information of the electric water heater so as to control the electric water heater.

[0027] The electric water heater control method can be applied to the electric water heater, or can also be applied to a terminal device capable of being communicatively connected to the electric water heater, or can also be applied to a server.

[0028] Referring to Figure 2 , Figure 2 is an application scenario diagram of an electric water heater control method provided by an embodiment of the present application.

[0029] As Figure 2 shown, a server can obtain historical usage data from a terminal device, obtain control information of an electric water heater according to the electric water heater control method, and send the control information of the electric water heater to the terminal device so as to control the electric water heater according to the control information of the electric water heater.

[0030] As Figure 1 shown, the electric water heater control method includes steps S101 to S105.

[0031] Step S101, obtaining historical usage data of an electric water heater.

[0032] Exemplarily, a day is equally divided into a plurality of time periods, and usage data of each day in the plurality of time periods is recorded to form the historical usage data of the electric water heater. For example, 24 hours of a day are equally divided into 24 time periods, and usage data of the electric water heater in each of the 24 time periods of each day is recorded to form the historical usage data of the electric water heater.

[0033] Step S102, determining a plurality of first target historical dates and a plurality of second target historical dates according to a current date, wherein a date interval of adjacent first target historical dates is less than a date interval of adjacent second target historical dates.

[0034] It can be understood that the date interval of adjacent first target historical dates is greater than zero, and the date interval of adjacent second target historical dates is greater than zero.

[0035] In some embodiments, a first date interval is obtained, and the plurality of first target historical dates is determined according to the first date interval and the current date. It can be understood that the first date interval can be pre-set or set by a user. It can be understood that the number of the first target historical dates can be pre-set, can be set by a user, or can not be set.

[0036] In some embodiments, a second date interval is obtained, and a plurality of second target historical dates are determined according to the second date interval and the current date, wherein the first date interval is smaller than the second date interval. It can be understood that the second date interval can be pre-set or set by the user. It can be understood that the number of the second target historical dates can be pre-set, set by the user or not set.

[0037] Optionally, the plurality of first target historical dates and the plurality of second target historical dates are determined according to the current date, comprising:

[0038] The plurality of historical dates adjacent to the current date are determined as the plurality of first target historical dates, and the plurality of first target historical dates are also sequentially adjacent to each other by one day.

[0039] The plurality of historical dates adjacent to the current date are determined as the plurality of first target historical dates, and the plurality of first target historical dates are also sequentially adjacent to each other by one day.

[0040] In some embodiments, the first date interval is set to be one day, one of the plurality of first target historical dates is one day apart from the current date, and the plurality of first target historical dates are sequentially adjacent to each other by one day.

[0041] In some embodiments, the second date interval is set to be one week, one of the plurality of second target historical dates is one week apart from the current date, and the plurality of second target historical dates are sequentially adjacent to each other by one week.

[0042] In some embodiments, the second date interval is set to be one week, one of the plurality of second target historical dates is one week apart from the current date, and the plurality of second target historical dates are sequentially adjacent to each other by one week.

[0043] Optionally, the historical usage data includes the water usage time period and / or the non-water usage time period of at least one of the plurality of historical dates, or the historical usage data includes the total water usage of different time periods in the plurality of historical dates.

[0044] In some embodiments, when a water use instruction of a user is detected, the time corresponding to the water use instruction can be acquired, the water use amount corresponding to the water use instruction can be counted, the water use amount corresponding to the water use instruction can be recorded in a corresponding time period according to the time corresponding to the water use instruction, and the total water use amount of the time period can be determined. If multiple water use instructions of a user are detected in a same time period, the water use amount corresponding to each water use instruction can be determined, the water use amounts corresponding to the multiple water use instructions can be recorded and counted, and the total water use amount of the time period can be determined. For example, in a same time period, the user opens and closes the mixing valve of the electric water heater multiple times during hand washing or bathing, the water use amount corresponding to each opening and closing of the mixing valve of the electric water heater can be determined, the water use amounts corresponding to the multiple opening and closing of the mixing valve of the electric water heater can be recorded and counted, and the total water use amount of the time period can be determined.

[0045] It can be understood that after the total water use amount corresponding to the time period is determined, it can be further determined whether the time period is a water use time period by a certain condition, the time period can be filled with a corresponding determination mark in the historical use data according to the determination result, for example, the water use time period mark can be 1, and the non-water use time period mark can be 0. If the determination mark corresponding to a time period of a historical date in the historical use data is 1, it is determined that the time period of the historical date is a water use time period. If the determination mark corresponding to a time period of a historical date in the historical use data is 0, it is determined that the time period of the historical date is a non-water use time period.

[0046] Optionally, according to the historical use data, it is determined whether the target time period is a water use time period in the first target historical date and the second target historical date, comprising:

[0047] If the total water use amount of the time period corresponding to the target time period in the first target historical date is greater than or equal to the predetermined water use amount, it is determined that the target time period is a water use time period in the first target historical date.

[0048] If the total water use amount of the time period corresponding to the target time period in the second target historical date is greater than or equal to the predetermined water use amount, it is determined that the target time period is a water use time period in the second target historical date.

[0049] In some embodiments, it is determined whether a time period of a historical date is a water use time period according to whether the total water use amount corresponding to the time period of the historical date is greater than or equal to a predetermined water use amount.

[0050] In some embodiments, after determining the first target historical date, it can be determined whether the target time period is a water use time period in the first target historical date according to whether the total water use amount of the time period corresponding to the target time period in the first target historical date is greater than or equal to the predetermined water use amount; after determining the second target historical date, it can be determined whether the target time period is a water use time period in the second target historical date according to whether the total water use amount of the time period corresponding to the target time period in the second target historical date is greater than or equal to the predetermined water use amount.

[0051] In some embodiments, after determining the first target historical date, the determination identifier of the time period corresponding to the target time period in the first target historical date can be obtained, so as to determine whether the target time period is a water use time period in the first target historical date; after determining the second target historical date, the determination identifier of the time period corresponding to the target time period in the second target historical date can be obtained, so as to determine whether the target time period is a water use time period in the first target historical date.

[0052] Step S104, determining whether the target time period is a preheating time period in the current date according to the determination result of whether the target time period is a water use time period in the first target historical date and the second target historical date.

[0053] Optionally, determining whether the target time period is a preheating time period in the current date according to the determination result of whether the target time period is a water use time period in the first target historical date and the second target historical date, comprises:

[0054] If the number of days that the target time period is a water use time period in the plurality of first target historical dates is greater than the first day threshold, and / or the number of days that the target time period is a water use time period in the plurality of second target historical dates is greater than the second day threshold, it is determined that the target time period in the current date is a preheating time period.

[0055] Optionally, the first day threshold can be 80% to 100% of the number of the first target historical dates, and the second day threshold can be 80% to 100% of the number of the second target historical dates. It can be understood that the first day threshold or the second day threshold can be pre-set or set by the user.

[0056] For example, if the number of days that the target time period is a water use time period in the plurality of first target historical dates is greater than the first day threshold, and / or the number of days that the target time period is a water use time period in the plurality of second target historical dates is greater than the second day threshold, it is determined that the target time period in the current date is a preheating time period, comprising:

[0057] If the target time period is a water use time period in the plurality of first target historical dates, it is determined that the target time period in the current date is a preheating time period.

[0058] if the target time period is not a water-using time period in at least one first target historical date, determining whether the target time period is a water-using time period in a plurality of second target historical dates;

[0059] if the target time period is a water-using time period in the plurality of second target historical dates, determining that the target time period of the current date is a preheating time period.

[0060] In some embodiments, the number of the first target historical dates can be set to three, the number of the second target historical dates can be set to two, the first day threshold can be set to three days, and the second day threshold can be set to two days.

[0061] It can be understood that, in general, the time period in which the user uses the electric water heater is accidental.

[0062] For example, if the target time period is from 12:00 to 13:00, and if it is directly determined that the target time period of the current date is a preheating time period according to the fact that the time period from 12:00 to 13:00 of the day before the current date is a water-using time period, the electric water heater can be automatically scheduled to heat in a situation where the user does not need to use water. Therefore, it is necessary to further determine whether the time period from 12:00 to 13:00 of the three days before the current date is a water-using time period, and according to the fact that the time period from 12:00 to 13:00 of the three days before the current date is a water-using time period, it can be determined that the target time period of the current date is a preheating time period, thereby improving the accuracy of the automatic scheduling of the electric water heater.

[0063] It can be understood that, in general, the time period in which the user uses the electric water heater on weekdays and non-weekdays can be quite different.

[0064] For example, according to historical use data, it is determined that the water-using time period of the user on Monday to Friday is from 20:00 to 21:00 and from 21:00 to 22:00, and the water-using time period of the user on Saturday to Sunday is from 18:00 to 19:00 and from 19:00 to 20:00.

[0065] In some embodiments, the target time period is from 18:00 to 19:00, the current date corresponds to Saturday, and if it is directly determined that the target time period of the current date is not a preheating time period according to the fact that the time period from 18:00 to 19:00 on Wednesday, Thursday, and Friday is not a water-using time period, the electric water heater can not be automatically scheduled to heat in a situation where the user needs to use water. Therefore, it is necessary to further determine whether the time period from 18:00 to 19:00 of the two Saturdays before the current date is a water-using time period, and according to the fact that the time period from 18:00 to 19:00 of the two Saturdays before the current date is a water-using time period, it can be determined that the target time period of the current date is a preheating time period, thereby improving the comprehensiveness of the automatic scheduling of the electric water heater.

[0066] Exemplarily, the method further comprises:

[0067] if the target time period is not a water-using time period in the at least one second target historical date, a third target historical date is determined according to the current date, wherein the date interval between the current date and the third target historical date is three weeks;

[0068] if the target time period is a water-using time period in the third target historical date, it is determined that the target time period of the current date is a preheating time period;

[0069] if the target time period is not a water-using time period in the third target historical date, it is determined that the target time period of the current date is a non-preheating time period.

[0070] In some embodiments, if the target time period cannot be determined through the acquired plurality of first target historical dates and the plurality of second target historical dates, the third target historical date is continuously acquired, and whether the target time period of the current date is a preheating time period is determined by determining whether the target time period is a water-using time period in the third target historical date.

[0071] In step S105, if the target time period of the current date is a preheating time period, the electric water heater is controlled to heat in the target time period.

[0072] In some embodiments, according to the determination that the target time period of the current date is a preheating time period when the number of days in which the target time period is a water-using time period in the plurality of first target historical dates is greater than the first day threshold, the total water usage and the water temperature of the corresponding first target historical date are acquired, the estimated water usage of the target time period of the current date is determined according to the total water usage of the plurality of first target historical dates, and the estimated water temperature of the target time period of the current date is determined according to the water temperature of the plurality of first target historical dates. Similarly, the estimated water usage of the target time period of the current date is determined according to the total water usage of the plurality of second target historical dates, and the estimated water temperature of the target time period of the current date is determined according to the water temperature of the plurality of second target historical dates, or the estimated water usage of the target time period of the current date is determined according to the total water usage of the third target historical date, and the estimated water temperature of the target time period of the current date is determined according to the water temperature of the third target historical date.

[0073] In some embodiments, after determining the estimated water usage and the estimated water temperature of the target time period of the current date, the real-time water temperature inside the inner container of the electric water heater is detected, and the electric water heater is controlled to heat in the target time period of the current date in combination with the real-time water temperature inside the inner container of the electric water heater.

[0074] Optionally, the method further comprises:

[0075] counting the number of record days of the historical usage data;

[0076] if the number of record days corresponding to the current date is less than or equal to the first record day threshold, and the target time period of the current date is a non-preheating time period, a preset preheating time period is acquired.

[0077] The electric water heater is controlled to heat at the preset preheating time period.

[0078] It can be understood that when the recorded historical use data is less, it is easy to cause that the current date target time period cannot be analyzed as a preheating time period based on the current historical use data.

[0079] In some embodiments, a first record day threshold and a preset preheating time period can be set, and the electric water heater is controlled to heat at the preset preheating time period. It can be understood that the preset preheating time period can be preset or set by the user.

[0080] It can be understood that the preset preheating time period also corresponds to a preset expected water consumption and a preset expected water temperature. By detecting the real-time water temperature inside the inner tank of the electric water heater, the preset expected water consumption and the preset expected water temperature are combined to control the electric water heater to heat at the preset preheating time period, so that in the early stage of use of the electric water heater, the situation that the user forgets to manually preheat but needs to use the electric water heater at the preset preheating time period can be reduced.

[0081] Optionally, it further comprises:

[0082] If the record days corresponding to the current date are greater than the second record day threshold, a fourth target historical date is determined according to the current date and the second record day threshold.

[0083] The historical use data corresponding to the fourth target historical date is deleted.

[0084] In some embodiments, if the number of the first target historical dates and the number of the second target historical dates are not set, if the data amount of the historical use data is too large, the workload of analyzing whether the current date target time period is a preheating time period also increases accordingly, and if the distance from the current date is too far away, the accuracy of the automatic preheating of the electric water heater will also be reduced to some extent, so part of the historical use data needs to be deleted.

[0085] In some embodiments, if the number of the first target historical dates and the number of the second target historical dates are set, if the data amount of the historical use data is too large, whether the current date target time period is a preheating time period can be determined according to part of the historical use data, and then the excessive historical use data can be deleted.

[0086] In some embodiments, the record days of the historical use data can be set to a second record day threshold, and if the record days corresponding to the current date are greater than the second record day threshold, the historical use data corresponding to the date interval of the second record day threshold from the current date is deleted, so that the data amount of the historical use data is prevented from being too large.

[0087] This application embodiment obtains historical usage data of the electric water heater, determines multiple first target historical dates and multiple second target historical dates based on the current date, wherein the date interval between adjacent first target historical dates is less than the date interval between adjacent second target historical dates. Based on the historical usage data, it is determined whether the target time period is a water usage period within the first and second target historical dates. Based on the determination result of whether the target time period is a water usage period within the first and second target historical dates, it is determined whether the target time period of the current date is a preheating period. If the target time period of the current date is a preheating period, the electric water heater is controlled to heat during the target time period, thereby improving the accuracy and comprehensiveness of the automatic scheduled heating control of the electric water heater and enhancing the user experience.

[0088] Please see Figure 3 , Figure 3 This is a schematic block diagram of the structure of an electric water heater provided in an embodiment of this application.
