The invention discloses an electric water heater and a control method for the electric water heater, wherein the electric water heater comprises: a casing, the casing is provided with a water inlet pipe and a water outlet pipe; The water chamber, the water inlet pipe and the water outlet pipe are respectively connected with the water storage chamber; the heater, the heater is used to heat the water stored in the liner; the safety valve, the safety valve is set at the water inlet of the water inlet pipe; the pressure detection module , the pressure detection module is used to detect the pressure in the inner tank and the pressure in the external water source pipeline to generate a pressure detection value; the control module is connected to the heater and the pressure detection module respectively, and the control module is used for when the pressure detection value is greater than When it is equal to the preset pressure threshold, the heater is controlled to stop heating to prevent water leakage from the safety valve. The electric water heater and the control method for the electric water heater according to the embodiments of the present invention can effectively avoid the water leakage problem of the safety valve caused by the excessive pressure in the inner tank.
Description
technical field [0001] The invention relates to the technical field of electrical appliances, in particular to an electric water heater and a control method for the electric water heater. Background technique [0002] An electric water heater is a type of water heater that mainly uses electricity as an energy source to heat water. According to the heating power, electric water heaters can be divided into three types: water storage type, instant heating type, and rapid heating type. Wherein, the water inlet of the storage type electric water heater is provided with a safety valve. When the pressure of tap water or the pressure in the inner tank of the electric water heater exceeds the preset pressure value of the safety valve, the water can be leaked out by opening the outlet of the safety valve to reduce the pressure, so as to prevent the inner tank from being subjected to excessive pressure. [0003] However, reducing the pressure of the inner tank through the leakage of ...
