Description

technical field [0001] The present invention relates to a fast heater. Background technique [0002] Existing water heating device utilizes electromagnetic induction to heat a magnetic conductor, and the water is heated through direct heat exchange with the heating element. The water is isolated from the electromagnetic coil with electricity by a relatively thick insulator. The thickness of the insulator is related to the heating The efficiency correlation is small. Although the safety and efficiency are relatively easy to improve, there are still many problems. For example, due to structural problems, the electromagnetic heating coil will be burned due to poor heat dissipation during work, and there is parasitic air between the electromagnetic heating coil and the water. Capacitance exists, and the high-frequency alternating current added to the electromagnetic heating coil will electrify the water through this parasitic capacitance, which will affect the efficiency and saf...
