Embodiment Construction

[0008] Embodiment 1 of the present invention is a cylindrical electromagnetic heating core, as shown in FIG. 1 .

[0009] The cylindrical electromagnetic heating core includes an excitation winding and a ferromagnetic heating element. The excitation winding coil 5 is wound into a cylindrical shape, and the whole is sealed in an insulating material that has little influence on the magnetic field lines, has good water permeability resistance, and has a certain heat resistance, forming a cylindrical winding sealing body 6 . There are several insulating and heat-resistant feet 10 separated from each other at the bottom of the winding sealing body 6, and the winding sealing body 6 is fixed and erected on the insulating and heat-resistant base 7. The gap between the bottom of the winding sealing body 6 and the base 7 is 2 ~50 mm. The lead-out wire 8 of the winding 5 is placed under the winding sealing body 6 and placed in certain two legs 10 to seal the lead-out base 7 . There is ...

Abstract

An electromagnetic heating element of water heater has exciting winding sealed in insulating material to constitute sealed winding, is supported by legs on the base seat with some interval in between. Two heating bodies locate on two sides of the sealed winding with 1-50 mm interval in between. There are leading out wires inside the legs and sealed base seat, several magnetic conducting strips connected to the heating body and fixed to the saeled winding and base seat connected to a water container. The saled winding and the heating body are socked in the water container, so that water flows between the sealed winding and the heating body. The sealed winding and the heating body may be produced into tubular or cake shaped. The present invention has the advantages of high electromagnetic conversion efficiency, high heat conversion efficiency, small heat inertia, etc.

Description

(1) Technical field [0001] The invention relates to an electromagnetic heating core for a water heater. (2) Technical background [0002] There are a variety of electromagnetic heating cores for water heaters that use the principle of electromagnetic heating, but the current design has the defect of low electrothermal conversion efficiency, and at the same time, because electricity and heat cannot be completely separated, they are easily damaged and difficult to ensure safety. (3) Contents of the invention [0003] The purpose of the present invention is to design an independent electromagnetic heating core component for water heaters, which has high electrothermal conversion efficiency, complete isolation of water and electricity, and basic isolation of electricity and heat, which can ensure safe use and long service life. [0004] The electromagnetic heating core of the water heater designed by the present invention includes an excitation winding and a ferromagnetic heat...
