Abstract

The invention relates to an instantaneous water heater achieving high-frequency electromagnetic induction heating. Based on the high-frequency electromagnetic induction principle, high-frequency induction current is used for enabling ferrite stainless steel pipes to generate vortex to generate heat rapidly, and water flowing through the stainless steel pipes is rapidly heated with high power; an induction heating assembly is an induction heating coil assembly formed by sealing and fixing induction coils as a whole through high temperature resisting silica gel, and the induction heating assembly is inserted in an annular clearance of an inner and outer pipe composite heating pipe, so that the outer wall of an inner pipe and the inner wall of an outer pipe receive a high-frequency induction magnetic field at the same time to generate vortex to generate heat rapidly; due to the fact that inner and outer induction heating is carried out at the same time through the induction coils, the heating speed is high, no heating power attenuation exists during long-time use, and the electrothermal conversion efficiency is high; due to the fact that three layers of stainless steel plates are arranged on the outer portions of the coils for shielding, electromagnetic radiation is effectively avoided; due to induction heating, electric insulation and isolation are higher, and the hidden danger of electric shocks is effectively avoided; and due to the action of induction heating high-frequency alternating current, water scale is avoided, and the service life of the water heater is prolonged greatly.

Description

technical field [0001] This patent relates to the technical field of electromagnetic induction heating, in particular to a high-frequency electromagnetic induction heating instant water heater. Background technique [0002] At present, traditional fast electric water heaters generally use heating methods such as electric heating wire heating tubes, electrode heaters, and quartz tube external coating heating tubes, which generally have safety hazards such as attenuation of heating efficiency, serious scaling, short service life, and water and electricity leakage. [0003] A fast water heater with high-frequency electromagnetic induction heating; it adopts electromagnetic induction heating, has fast heating speed, high electrothermal conversion efficiency, is not easy to scale, and has a long service life. reliable. Contents of the invention [0004] The purpose of this patent is to provide a high-frequency electromagnetic induction heating fast water heater for traditional...
