Problems solved by technology

[0002] Existing water heaters are mainly gas-fired water heaters, and personal injuries caused by carbon monoxide poisoning and hypoxia are unavoidable for such water heaters; The power is very large, and a thick power cord is required, which is not suitable for ordinary households. The energy utilization rate of the above products is only 50-60%.

Abstract

The invention provides an electromagnetic induction water heater consisting of a shell, a soleplate, a circuit board, a generated electromagnetic induction heating part and an iron-made water container heated part; after a power supply is started to work, the current of an induction heating coil forms a circuit by passing through a gated pipe so as to generate the high-frequency alternating current, thus forming the alternating magnetic field in the heating coil and generating the variational magnetic lines; the magnetic lines magnetize the iron-made water container and induces the electromagnetic eddy; as the self impedance of the water container converts the electric energy into the heat energy which heats the water in the iron-made water container; simultaneously, the induction heating coil symmetrically generates the magnetic lines, thus heating the water in the iron-made water container arranged on two surfaces of the heating coil and leading the heat efficiency to reach the maximum; furthermore, more than one heating coils can be used.

Description

technical field [0001] The invention relates to an electromagnetic water heater for kitchen and bathroom supplies heated by electromagnetic induction. Background technique [0002] Existing water heaters are mainly gas-fired water heaters, and personal injuries caused by carbon monoxide poisoning and hypoxia are unavoidable for such water heaters; The power is very large, and a thick power cord is required, which is not suitable for ordinary households. The energy utilization rate of the above products is only 50-60%. Contents of the invention [0003] The invention makes a new design for the heating part of the existing electric water heater, adopts the principle of electromagnetic induction heating, and indirectly heats the water in the water container made of iron soft magnetic material, and the circuit elements of this product are completely separated from the water. [0004] The present invention is achieved in this way: the electromagnetic induction water heater inc...
