Electro-magnetic induction heating rice cooker

Abstract

The invention discloses an electro-magnetic induction heating rice cooker, relating to the technical field of kitchen appliances, and solving the problem about the low heating efficiency of the heating wire coil of the existing electro-magnetic induction heating cookware. The electro-magnetic induction heating rice cooker disclosed by the embodiment of the invention comprises a cooling fan, a protective cover and a heating coil, wherein the heating coil comprises a bottom heating coil and a side heating coil; the bottom heating coil is installed on the bottom part of the protective cover; the side heating coil is installed on the bottom side wall of the protective cover in an intertwining way; a plurality of support ribs arranged along the radial direction are arranged on the side wall of the protective cover; the side heating coil is erected on the support ribs; the clearances between the side heating coil and the side wall of the protective cover form a heat dissipation passage; the side heating coil is formed by the harnesses of flat wires in the intertwining way; a slot is formed on each support rib; and the flat wires are plugged into the slots. The electro-magnetic induction heating rice cooker is mainly used as the cookware, including electro-magnetic heating rice cookers, electro-magnetic heating electric pressure cookers and the like.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to an electromagnetic induction heating rice cooker used in kitchen appliances. Background technique [0002] In existing rice cookers such as electric rice cookers and electric pressure cookers that use electromagnetic induction heating, heating coils are generally wound on the bottom and sides, and high-frequency currents are input into the heating coils to generate alternating magnetic fields around them; since the inner pot generally uses Iron and nickel can be made of magnetically conductive materials, and the above-mentioned alternating magnetic field can enable the eddy current to be generated by itself, so that the inner pot itself generates heat and plays a heating role. [0003] In the process of realizing and using the above-mentioned electromagnetic induction heating rice cooker, the inventor found at least the following problems in the prior art: the efficien...

AI Technical Summary

Problems solved by technology

[0003] In the process of realizing and using the above-mentioned electromagnetic induction heating rice cooker, the inventor found at least the following problems in the prior art: the efficiency of electromagnetic induction heating is low, and it cannot meet the requirements of higher energy efficiency levels. Forcibly achieve a higher energy efficiency level in the scheme, which will cause the heating coil to generate a large amount of heat. Based on the existing scheme with poor heat dissipation effect, it is easy to cause burn-in; in addition, the heating coils are tightly wound, and adjacent coils It is easy to short circuit at high temperature and cause burn-in
