Wirelessly-powered electric water heater and power supply and control method of wirelessly-powered electric water heater

Abstract

The invention discloses a wirelessly-powered electric water heater and a power supply and control method of the wirelessly-powered electric water heater. The wirelessly-powered electric water heater comprises an energy emitting end, an energy receiving end, a heating pipe, a detector and a processor, wherein the energy emitting device is connected with an alternating-current power source and used for converting the alternating-current power source into a high-frequency alternating-current power source and converting the high-frequency alternating-current power source into a high-frequency electromagnetic field; the energy receiving end is used for generating electric energy by means of the high-frequency electromagnetic field; the heating pipe is used for heating water in an inner container of the wirelessly-powered electric water heater by means of the electric energy generated by the energy receiving end; the detector is used for detecting the current of the high-frequency alternating-current power source; and the processor is used for judging a circuit fault of the energy receiving end according to the current. According to the wirelessly-powered electric water heater, the electricity utilization safety of the electric water heater can be further improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a wireless power supply electric water heater and a power supply and control method for the wireless power supply electric water heater. Background technique [0002] The popularity of electric water heaters has greatly improved the comfort and convenience of people's daily life. At present, electric water heaters are mostly connected to the mains through cables to obtain the required electric energy. However, electric water heaters are generally used in humid environments such as bathrooms, so cables and plugs will bring dangers such as leakage or short circuit. And in a humid environment, cables and plugs are easily corroded, thus further increasing the safety hazard. [0003] In the related art, a wireless power supply method for electric water heaters is proposed, that is, the electric water heater has a power supply side and a power receiving side, the power s...

AI Technical Summary

Problems solved by technology

[0004] However, since the body of the electric water heater is electrically connected to the power receiving side, and water is conductive, when the circuit on the power receiving side fails, there is still a risk of leakage at the water outlet of the electric water heater

Therefore, the electricity safety of electric water heater needs to be further improved.
