Low-heating electromagnetism generating method and device thereof of electromagnetic water heater

Abstract

A low-heating electromagnetism generating method and a device thereof of an electromagnetic water heater aim to overcome defects that electronic components on a circuit board are poorer in working performance and easy to be damaged or joints thereof are easy to loosen and the like due to too much heat of an electromagnetic coil when a single electromagnetic coil generates electromagnetic vortex and is high in power in the prior art. The low-heating electromagnetism generating method includes that a resonance inverter circuit of the electromagnetic water heater is utilized to generate alternating magnetic field by the aid of electromagnetic coils, and generates electromagnetic vortex for a water passing magnetism-conductive metal barrel of a central core or a magnetism-conductive metal body in a water passing barrel so that the water passing magnetism-conductive metal barrel or the magnetism-conductive metal body in the water passing barrel heat automatically to heat water flowing through the barrels. The low-heating electromagnetism generating method is characterized in that more than two electromagnetic coils are parallelly arranged on the outer side of the water passing magnetism-conductive metal barrel or the water passing barrel with the magnetism-conductive metal body inside and are correspondingly connected with the resonance inverter circuit after being connected in parallel, and heat of the electromagnetic coils during working is reduced by reducing resistance thereof.
