Electromagnetic water heater

Abstract

The invention discloses an electromagnetic water heater which comprises a shell for accommodating various components. The shell at least accommodates a heating water disc, an induction coil corresponding to the heating water disc, a water pipe and a circuit device, the water pipe is connected with the heating water disc, and the circuit device is connected with the induction coil. The electromagnetic water heater is characterized in that the heating water disc is provided with an upper water cover and a lower water cover, and a heating plate is arranged between the upper water cover and the lower water cover; a water tank is arranged on the upper water cover and/or the lower water cover respectively; and the upper water cover and the lower water cover are made of nonmetal materials, and the heating plate is made of magnetic-permeable metal materials. The heating water disc is made of nonmetal materials, so that the requirement on heat insulation is met, and structural strength of the electromagnetic water heater is improved.

Description

technical field [0001] The invention relates to a water heater, in particular to an electromagnetic water heater. Background technique [0002] Electromagnetic water heaters have a number of invention patents, most of which are induction coils set around the water pipes, so the water pipes and induction coils are in a small three-dimensional space. When the water pipe leaks, the water can easily touch the circuit and cause unsafe electricity use. The heating element in Chinese patent 200410013500.5 is in contact with water on one side, and the heat generated by the other side of the heating element will radiate to the induction coil, increasing the temperature rise of the coil and reducing the thermal efficiency. Chinese patent 200810123605.4 The use of metal materials for the water container to withstand water pressure is not conducive to heat preservation. When using non-metallic materials, it is necessary to increase the wall thickness or increase ribs and other reasons t...

Chinese patent 200810123605.4 The use of metal materials for the water container to withstand water pressure is not conducive to heat preservation. When using non-metallic materials, it is necessary to increase the wall thickness or increase ribs and other reasons to increase the distance between the coil and the heating body and increase the magnetic resistance of the magnetic circuit.
