S1, receiving a boiled water consumption instruction; specifically, the instruction of receiving boiled water may be an instruction input by a user through a button or the like, or may be that a time parameter is stored in the water heater 40, and when the current time reaches the time parameter, the water heater 40 is automatically started.
Step S2, judging whether a user uses hot water, if so, not performing operation; if not, the three-way valve 8 is controlled to be communicated with the connecting pipe 7, and the water pump 10 is started to circulate the water in the water inlet pipe 4, the water outlet pipe 5 and the connecting pipe 7; specifically, in the present embodiment, the water pump 10 is disposed on the water inlet pipe 4, and in other embodiments, the water pump 10 may be disposed on the water outlet pipe 5 or the connection pipe 7, and the specific location of the water pump 10 is not limited herein.
In the present embodiment, whether the user uses hot water is determined by detecting whether the circulation flow rate in the water heater 40 is equal to or greater than the start flow rate, if so, determining that the user is using hot water, and if not, determining that the user is not using hot water.
Step S3, detecting whether the water temperature reaches a first preset temperature, if so, turning off the water pump 10 and opening the boiled water outlet, and if not, keeping the water pump 10 running and keeping the boiled water outlet closed. Specifically, when the water temperature reaches the first preset temperature, the current water temperature is indicated to be capable of meeting the requirements of users, so that the boiled water outlet can be started, and boiled water can flow out from the boiled water outlet. When the water temperature cannot reach the first preset temperature, the current water temperature is indicated to be still required to be heated continuously. The water can be continuously circulated by the water pump 10.
When the water heater is particularly used, the control mode is adopted, a user can directly connect boiled water from the boiled water outlet, so that the boiled water can be prevented from flowing through the household pipeline, the pollution of water quality caused by low temperature resistance of materials of the household pipeline can be avoided, and the safety of the user in using the boiled water is improved. When the instruction of using boiled water is received and the user does not use the hot water, the hot water is heated through circulation, so that the heating efficiency is improved. In addition, when the user uses the hot water, even if the user receives a command of using the boiled water, the user is not operated, so that the boiled water can be prevented from directly coming out to scald the user, and the use safety of the user is improved.

In particular use, the control described above is employed to enhance the controllability of the water heater 40.
As shown in fig. 3, after step S102, the control method further includes:
Step S202, judging whether the water temperature in the water heater 40 is lower than a second preset temperature, if yes, controlling the three-way valve 8 to be communicated with the hot water outlet 6. Specifically, when the temperature of the water in the water heater 40 is lower than the second preset temperature, it indicates that the water in the water heater 40 directly flows out of the hot water outlet 6 and does not scald the user, so that the three-way valve 8 can be controlled to enable the water outlet 5 to be communicated with the hot water outlet 6, and the water in the water heater 40 can directly flow out of the hot water outlet 6. When the water temperature in the water heater 40 is not lower than the second preset temperature, it indicates that the user is scalded when the water in the water heater 40 directly flows out of the hot water outlet 6, so that the three-way valve 8 is controlled to prevent the water outlet 5 from being communicated with the hot water outlet 6 until the water temperature is lower than the second preset temperature, thereby preventing the user from being scalded and improving the use safety.
In this embodiment, the communication between the water outlet pipe 5 and the connecting pipe 7 and the switching between the water outlet pipe 5 and the hot water outlet 6 are realized by the three-way valve 8. In other words, by the cooperation of the water temperature in the water heater 40 and the communication between the switching pipelines of the three-way valve 8, the user can be prevented from being scalded, and the use safety is improved.

As shown in fig. 4, step S2021 is to determine whether the water temperature in the water outlet pipe 5 is lower than a third preset temperature; and/or whether the water temperature in the water tank 11 is lower than a fourth preset temperature. In other words, it may be determined whether only the water temperature in the water outlet pipe 5 is lower than the third preset temperature, or whether the water temperature in the water tank 11 is lower than the fourth preset temperature; or it may be determined whether the water temperature in the outlet pipe 5 is lower than a third preset temperature and whether the water temperature in the water tank 11 is lower than a fourth preset temperature.
When the three-way valve 8 is particularly used, the three-way valve 8 can be controlled to be communicated with the hot water outlet 6 only by meeting the condition that the water temperature in the water outlet pipe 5 is lower than a third preset temperature and the water temperature in the water tank 11 is lower than one of fourth preset temperatures, so that the operation efficiency of the steps is improved. By adopting the control mode, when the water temperature in the water outlet pipe 5 is lower than the third preset temperature and/or the water temperature in the water tank 11 is lower than the fourth preset temperature, the water temperature after the water in the water outlet pipe 5 and the cold water in the water tank 11 are mixed at the moment can be lower than the second preset temperature, so that the mixed water directly flows out of the hot water outlet 6 without scalding a user, and the use safety is improved. In other embodiments, the determination may be made in other ways, and is not limited in this regard.
In this embodiment, the third preset temperature is 50 degrees and the fourth preset temperature is 35 degrees.

By adopting the control mode, the water in the water inlet pipe 4, the water outlet pipe 5 and the connecting pipe 7 can be circularly heated to the first preset temperature, so that the requirement of a user on the water temperature is met.
In the present embodiment, whether the user uses hot water is determined by detecting whether the circulation flow rate in the water heater 40 is equal to or greater than the start flow rate, if so, determining that the user is using hot water, and if not, determining that the user is not using hot water. In other words, when the circulation flow rate is greater than the start flow rate, it is verified that the water in the water heater 40 is circulating at this time, and thus it can be indicated that the user is using hot water.
After step S3, the control method further includes:
The water in the inlet pipe 4, the outlet pipe 5 and the connection pipe 7 is heated according to a second preset load, wherein the second preset load is related to the inlet water temperature, the water flow and the specific heat capacity of the water. Specifically, substituting the water inlet temperature and the water flow into Q= (ty-tj) multiplied by Q multiplied by c to obtain a second preset load; wherein, ty is a first preset temperature; tj is the temperature of the inlet water; q is water flow; c is the specific heat capacity of water. The control mode is adopted so that the water heater 40 can be continuously input according to the first set temperature.
In this embodiment, ty is 95 degrees, and in an embodiment thereof, the value of ty may be adjusted according to the actual requirement, which is not limited herein.
Step S202 further includes: if yes, the water heater 40 is controlled not to heat, and if not, the water heater 40 is controlled to heat. By adopting the control mode, the method has the characteristic of saving resources.
