Energy-saving electromagnetic water heater

Abstract

The invention relates to an energy-saving electromagnetic water heater, which comprises a controller and a heating cavity made of metal as well as a heating body positioned in the heating cavity. The heating cavity is respectively connected with a water feeding pipe and a water discharging pipe and is externally provided with an electromagnetic coil externally as well as an insulated conductive layer installed or coated on the external surface; the electromagnetic coil is twined outside the insulated conductive layer, which is externally provided with an electromagnetic screening cap; further more, the heating body is in sheet shape, which is installed in cascade; a water flow channel is arranged between the heating sheets. The invention with the design has the advantages of rational structure, long service life and high heat utilizing efficiency without radicalization.

Description

technical field [0001] The invention relates to a water heater, in particular to an energy-saving water heater working on the principle of electromagnetic heating. Background technique [0002] Electromagnetic water heater is an electric heating appliance that uses the principle of electromagnetic induction to heat water. Although the technology of electromagnetic water heater has been born for many years, there are still some technical defects that need to be improved. The existing electromagnetic water heater uses the electromagnetic heating coil to use plastic pipes or other insulating materials. The sleeve is installed on the shell of the heating chamber as a bracket. The electromagnetic heating coil will burn out due to poor heat dissipation during work, shortening the service life of the equipment. Generate electromagnetic radiation, long-term use will affect people's health, because the above-mentioned unreasonable structure, heat utilization efficiency is not high, m...

[0002] Electromagnetic water heater is an electric heating appliance that uses the principle of electromagnetic induction to heat water. Although the technology of electromagnetic water heater has been born for many years, there are still some technical defects that need to be improved. The existing electromagnetic water heater uses the electromagnetic heating coil to use plastic pipes or other insulating materials. The sleeve is installed on the shell of the heating chamber as a bracket, and the electromagnetic heating coil will burn out due to poor heat dissipation during operation, shortening the service life of the equipment. Electromagnetic radiation is generated, and long-term use will affect people's health. Due to the above-mentioned unreasonable structure and low heat utilization efficiency, it is difficult to widely promote electromagnetic water heaters.
