Abstract
The invention discloses a control method and a relevant device for a water heating device. The method includes the steps that after the initial water temperature is acquired, the heating device is controlled to start heating; if the initial water temperature does not exceed a first preset temperature, the temperature rising time needed when the water temperature is risen to a second preset temperature from the first preset temperature is calculated, a prejudged delay temperature corresponding to the temperature rising time is calculated, if a first prejudged temperature reaches a preset target temperature, the heating device is controlled to stop heating after first preset time, and the first preset time corresponds to the time interval where the temperature rising time is located; and if the initial water temperature exceeds the first preset temperature, when a second prejudged temperature reaches a correction target temperature, the heating device is controlled to stop heating, the second prejudged temperature is the sum of a currently-detected water temperature and a preset delay temperature, and the correction target temperature is the difference obtained by subtracting a third preset temperature from the preset target temperature. By means of the technical scheme, power off can be performed in time after water reaches a boiling point, that is to say, the power-off time is short, and waste of electric power resources can be effectively avoided.
