Household electric cooker

Abstract

The invention provides a household electric cooker. The household electric cooker comprises a magnetic steel temperature limiter, the magnetic steel temperature limiter comprises an aluminum cover, asoft magnet, a soft support, a hard magnet, a hard support, an inner spring, a small cup and a pull rod, the soft magnet, the soft support, the hard magnet, the hard support and the inner spring are all located in the small cup, one end of the pull rod is fixedly connected with the hard support, the other end of the pull rod penetrates out of the small cup and is movably arranged, the inner springis arranged between the hard support and the aluminum cover, the soft magnet and the hard magnet are both located in the inner spring, the magnetic steel temperature limiter further comprises a temperature sensing deformation component, the temperature sensing deformation component is located in the inner spring, one end of the temperature sensing deformation component is fixedly connected with the soft support, and the other end of the temperature sensing deformation component directly faces the hard support. The problem that a magnetic steel temperature limiter is burnt down and even a firedisaster is caused due to the fact that a heat preservation piece and a contact on a lever of an electric cooker are sintered and bonded together and an inner spring in the magnetic steel temperaturelimiter cannot drive the heat preservation piece to be separated from the lever contact through a pull rod can be avoided.

Description

technical field [0001] The invention relates to the technical field of electric rice cookers, in particular to a household electric rice cooker. Background technique [0002] Rice cookers generally include a magnetic steel temperature limiter and a thermal insulation sheet. The magnetic steel temperature limiter is a temperature controller with hard and soft magnets. It belongs to a mechanical device that can realize automatic power-off of rice cookers. It is mainly composed of soft magnets without magnetism and hard magnets with permanent magnetism. When the hard magnet is close to the soft magnet at room temperature, the magnetic field of the hard magnet will magnetize the soft magnet, and then the two will be adsorbed. When the temperature rises to the Curie temperature point of the soft magnet, the magnetism of the soft magnet will decrease or even disappear, thus The two are separated under the elastic force of the inner spring; when the temperature drops below the Cur...

AI Technical Summary

Problems solved by technology

[0004] Based on this, in order to overcome the fact that after the existing rice cooker cooks the rice, the insulation sheet and the contact on the lever of the rice cooker will be sintered and stuck together, and the inner spring in the magnetic steel temperature limiter cannot drive the insulation sheet and the lever contact through the pull rod to separate , and then burn down the magnetic steel temperature limiter or even cause a fire problem, the invention provides a household electric cooker, and its specific technical scheme is as follows:
