When a user needs to intelligently control the water heater, the terminal can be connected with the water heater through the network interface. The connection mode may be WIFI (Wireless Fidelity, Wireless local area network) connection or bluetooth connection.
Under the condition that the terminal is connected with the water heater, a user can input a control instruction through an intelligent household appliance control interface of the terminal. After the water heater receives the control instruction, historical water consumption information of the user at each moment in a historical period, which is collected by a bottom plate of the water heater, is reported to the middleware. The middleware stores the historical water consumption information in the data warehouse according to a certain rule, and the data warehouse analyzes the water outlet flow in the water consumption information, so that the water consumption time period of the water heater in the historical reported data can be obtained.

The number of the water consumption time periods in the historical reported data is multiple, and this embodiment does not specifically limit this.
The historical water use information may be stored in a preset time period, or the like. For example, one day is divided into a plurality of preset time periods, and the historical water consumption information of each preset time period is separately stored.
102, acquiring the heating starting time of a hot water circulation system of the water heater in the current period according to the water using time period and the predetermined heating time; wherein the heating starting time is earlier than the starting time of the water using time period;

At the beginning of the water using time period, the temperature of the water in the water outlet pipe is just the outlet water temperature. The user can directly use the hot water with the outlet water temperature.
When the user opens the hot water valve at the starting moment of the water use time period, the hot water with the water temperature of the water use time period directly flows out of the water outlet pipe, the user can directly use the hot water, and the water resource waste and the long waiting time caused by the fact that the hot water can be used after all the original cold water in the waiting water outlet pipe is discharged are effectively reduced.
For example, the water is used for a period of 7:00 to 7:30, the starting time is 7:00, and the predetermined heating period is 10 minutes. And controlling the hot water circulation system to heat the water in the water outlet pipe at the heating starting time 6:50 until the water temperature in the water outlet pipe reaches the water outlet temperature and/or the heating time reaches the water outlet temperature in the water using time period.

In the embodiment, by learning the historical water consumption information and combining the environmental temperature of the environment where the water heater is located in the current period, the heating starting time when the hot water circulating system preheats the water in the water outlet pipe is accurately obtained, and the hot water circulating system is controlled to preheat the water in the water outlet pipe at the heating starting time, so that the water in the water outlet pipe is just heated at the starting time of the water consumption time period, the waste of water resources and the long waiting time are effectively reduced, the working time of the hot water circulating system is saved to the greatest extent, and the energy consumption is reduced.
And when receiving a control instruction input by a user through a terminal, the system can learn historical water consumption information for a long time, and automatically control the hot water circulation system to heat in advance, so that the user is prevented from operating and controlling the water heater in advance when using the water heater every time, and the user can use the water heater more conveniently.
And when a stop control instruction input by a user through the terminal is received, the automatic heating function of the hot water circulating system is closed. Through this kind of mode, the user can remote control water heater, not only easy operation can use the water heater more conveniently and intelligently moreover.
On the basis of the foregoing embodiment, in this embodiment, obtaining the heating duration according to the ambient temperature of the water heater in the current period and the outlet water temperature includes: calculating first output power required by the hot water circulation system to heat water in the water outlet pipe according to the water amount in the water outlet pipe in the current period, the environment temperature and the water outlet temperature; and dividing the first output power by a second output power of the hot water circulating system in unit time length, and taking the division result as the heating time length.
Optionally, the second output power of the hot water circulation system in the unit time length can be obtained by calculation according to the working parameters of the hot water circulation system. For example, the rated output power and the heating efficiency in the working parameters of the hot water circulation system are multiplied to obtain the rated output power and the heating efficiency.
Wherein T is the heating time, c is the specific heat capacity of water, m is the water quantity in the water outlet pipe, Δ T is the temperature difference between the water outlet temperature and the ambient temperature, cxmxΔ T is the first output power required by the hot water circulation system for heating, and P is the second output power of the hot water circulation system in unit time.

In order to solve the above problem, the present embodiment combines the water usage periods in which water is frequently turned on and off and the partial water usage periods having a short time interval, and controls the hot water circulation system according to the combined water usage periods.
Optionally, if the difference between the starting time of the next water using time period and the ending time of the previous water using time period in any two adjacent water using time periods is smaller than a second preset threshold, the two water using time periods are combined into a new water using time period. Wherein, the starting time of the former water using time period is earlier than the starting time of the latter water using time period.

Alternatively, the merging mode may be to take a time period between the start time of the previous water usage time period and the end time of the next water usage time period as the new water usage time period.
For example, the two adjacent water consumption periods are 7:00 to 7:20, and 7:24 to 7:40, the starting time and the ending time of the previous water using time period are respectively 7:00 and 7:20, and the starting time and the ending time of the next water using time period are respectively 7:24 and 7: 40. Wherein, the time difference between the starting time 7:24 of the next water using time period and the ending time 7:20 of the previous water using time period is 4 minutes and less than 5 minutes, and the two water using time periods can be combined to form a new water using time period of 7:00 to 7: 40.
In addition, the starting time of the combined new water using time period is used as a new water boiling time; and combining the water outlet temperatures of any two adjacent water using time periods into a new water outlet temperature.

The prompting mode can be that the prompting message is stored in the database in advance, and under the condition that the terminal is connected with the water heater in a network, the prompting message in the database is pushed to the terminal through a calling interface.
The prompt message can be broadcasted by the terminal in the forms of voice, characters and the like.
In this embodiment, when the hot water circulation system completes heating, a prompt message indicating that the hot water circulation system completes heating is timely pushed to the user to prompt the user that the user can use hot water.
On the basis of the foregoing embodiments, in this embodiment, after the controlling the hot water circulation system to heat according to the outlet water temperature of the water heater in the water using time period, the heating start time, and the predetermined heating time period, the method further includes: and under the condition that the heating time of the hot water circulating system reaches the heating time, closing the hot water circulating system.
