At this time, the water outlet temperature of the water heater does not need to be adjusted, and the water heater still discharges water at the current first water outlet temperature.
And S28, adjusting the water outlet temperature of the water heater to the initial water outlet temperature.
The initial outlet water temperature is a common outlet water temperature of a user, such as a first outlet water temperature or a second outlet water temperature, and may also be an outgoing outlet water temperature of the water heater, which is not specifically limited herein and may be determined by a person skilled in the art according to actual needs. When the closing time period T _ OFF of the water heater is determined to be greater than or equal to the second preset time period, the water heater can be judged to be in an unused state, and the outlet water temperature of the water heater can be restored to the initial outlet water temperature for reuse.
According to the control method for the water outlet temperature of the water heater, provided by the embodiment of the invention, before the water outlet time is judged to be less than the first preset time, the closing time of the water outlet valve is obtained, so that the water outlet temperature of the water heater can be accurately adjusted by combining the water outlet time and the closing time of the water outlet valve. When the water outlet time length is detected to be more than or equal to the first preset time length, the first water outlet temperature meets the requirements of a user, at the moment, whether the closing time length is less than the second preset time length or not can be judged, when the closing time length is determined to be less than the second preset time length, the user is indicated to only temporarily close the water heater, at the moment, the water heater does not need to be subjected to temperature adjustment, water outlet is continuously carried out at the first water outlet temperature before the water outlet valve is closed, when the water outlet valve is opened again, the water outlet temperature of the water heater does not need to be adjusted by the user, and accurate control of the water outlet temperature. When the closing time is determined to be greater than or equal to the second preset time, the user stops using the water heater, and the water temperature of the water heater can be adjusted to the initial water temperature, so that the water heater is convenient for other users to use again.
