The embodiment of the invention provides a method for controlling a water heater and the water heater, and belongs to the field of electric appliances. The method comprises the following steps that whether a water flow signal came from a pipeline of the water heater exists or not is detected; whether an electric leakage signal exists in the water heater or not is detected; and when the water flowsignal is detected, and when the electric leakage signal exists as well, the water heater is switched from a mains supply to a standby power supply for power supply. According to the technical scheme,when water is discharged from the water heater, if an outer shell is detected to be electrified, the water heater is immediately switched to the standby power supply, and therefore under the situation that the water heater works continuously is guaranteed, the mains supply which is higher than a safety voltage of a human body is effectively cut off, so that the personal injury to a user is avoided when an accident electric leakage situation occurs, and the safety of the user is fully protected.
Description
technical field [0001] The invention relates to the field of electrical appliances, in particular to a method for controlling a water heater and the water heater. Background technique [0002] With the technological upgrading of water heaters, the mainstream water heaters currently on the market use electronic control systems to control and maintain the operation of water heaters. Most of the existing water heaters are powered by 220V mains electricity. However, due to the electricity problem in some families, the case of the water heater often has a charged case when it is in use, that is, the case leaks electricity. Therefore, when users use it, there are certain potential safety hazards. In the prior art, when it is detected that the housing is electrified, the leakage protection is implemented by cutting off the power supply. Although this method can protect the user's safety, it also affects the user's experience and cannot make the user continue to use the water hea...
