Electric pressure cooker

Abstract

The invention provides an electric pressure cooker. The electric pressure cooker comprises a cooker body and a cooker cover hinged to the cooker body. The cooker cover is provided with an inductance coil and a magnetic conductive piece adjacent to the inductance coil. The magnetic conduction piece is rotationally mounted on the cooker cover and is always in a vertical state under the action of self gravity; when the cooker cover is switched between the cover closing state and the cover opening state, the projection area of the magnetic conductive part perpendicular to the surface of the inductance coil changes, the inductance value of the inductance coil changes, and whether the cooker cover is opened is judged according to the inductance value change of the inductance coil. According to the electric pressure cooker, when the cooker cover is switched between the cover opening state and the cover closing state, the projection area of the magnetic conduction part perpendicular to the surface of the inductance coil changes; the inductance value of the inductance coil is changed to judge whether the pot cover is opened, so that the pot cover can be directly opened and boiled without being rotated, the operation steps of a product are simplified, and the problem that pot teeth are scratched or even deformed due to the fact that a user forgets to rotate the pot cover is solved.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, to an electric pressure cooker. Background technique [0002] In the existing one-piece electric pressure cooker, in order to prevent the product from starting to heat when the lid is not screwed in place or not screwed together, causing the lid to fly out of the pot after the lid is pressed, it is necessary to design a The lid is in place detection device, the product can only start heating when the lid is screwed in place. When opening the lid, it is necessary to first rotate the lid from the buckled state to the non-fastened state, and then uncover the lid so that the lid is at an angle of 0 to 45 degrees with the vertical direction, so that the user can obtain or operate the inner pot. food. Because the pot cover is not rotated during the process of unfastening the pot cover from the non-fastened state to uncovering the pot cover, after the pot cover is uncovered, ...

AI Technical Summary

Problems solved by technology

However, after cooking with the lid off, users often forget to turn the lid back to the open state before closing the lid. Instead, they press down on the lid without rotating the lid. The teeth of the upper pot collide with the teeth of the outer pot, which can easily cause the two to collide with each other, and even cause the teeth to deform, resulting in poor screwing of the pot lid; and the existing scheme is cumbersome to operate, and the pot needs to be rotated when opening the lid to cook. After the lid is opened and cooked, the lid needs to be rotated again, so there is a lot of room for improvement in this existing solution
