Electric cooker

Abstract

The present invention provides a small electric rice cooker which can effectively reduce the magnetic field leakage to the outside of the electric rice cooker. It comprises: a cooker body; The cover of the opening; the steam spout on the bottom surface of the cover; the steam generating device provided with a container that can be assembled and disassembled for sending steam into the pot; the steam generating device installed on the container A heating coil for induction heating; and one or more conductive closed loop lines arranged outside the heating coil. In this way, there will be current flowing in the closed loop, and the generated magnetic field can offset the closed loop and the nearby magnetic field, which can effectively reduce the magnetic field leaked to the outside of the rice cooker, and suppress the temperature rise of the rice cooker body or components located outside the rice cooker.

Description

technical field [0001] The invention relates to an electric rice cooker which can be used in professional places such as ordinary families or restaurants. Background technique [0002] In recent years, the market for rice cookers that use electromagnetic induction for heating has been expanding. The structure of the traditional rice cooker is as image 3 shown in . image 3 Among them, 31 is a pot body with an opening on the upper surface, which is roughly cylindrical and covered by a cover 32 that can be opened and closed freely. The pot 33 is installed in the inside of the pot body 31 in a detachable manner. Inner pot 33 is made of magnetic materials such as stainless steel and iron. The inner pot 33 is loaded into the protective frame 34, which is made of non-metallic material and is cylindrical with a bottom. The bottom and outside of the protective frame 34 are provided with heating coils 35 for inductively heating the inner pot 33 . The heating coil 35 is composed o...

Problems solved by technology

[0005] However, in the existing induction heating antimagnetic method, since a wide cylindrical aluminum antimagnetic plate is provided inside, the size of the pot body will become larger compared with the inner pot of the electric rice cooker, which is inconvenient to carry. , Setting performance will deteriorate, etc.

In addition, there are also cases where it is not possible to install a magnetic shield due to the configuration of the substrate and the size of the pot.

Moreover, due to the difference in the type and capacity of the rice cooker, the shape of the antimagnetic plate will also be changed accordingly, and the antimagnetic plate cannot be used universally.
