Electric pressure cooker with adjustable pressure limiting value

Abstract

The invention discloses an electric pressure cooker with adjustable pressure limiting value. The electric pressure cooker comprises a cooker seat, a cooker body and a cooker cover, wherein the cookerseat, the cooker body and the cooker cover are matched in sequence from top to bottom and are fixedly connected; a connecting block is arranged at the upper part of the cooker cover; the connecting block and the cooker cover are fixedly connected through a bolt and a nut; the connecting block and the cooker body are connected through a foldable connecting part; a pressure limiting valve is arranged in the connecting block; a lifting handle is arranged at one side of the pressure limiting valve; one end of the lifting handle and one end of the pressure limiting valve are embedded into the cooker body respectively and are fixedly connected through a screw and a thread. According to the electric pressure cooker disclosed by the invention, a compression spring is matched with a pressure switchto use; when a heating disc sinks under the action of pressure, the heating disc moves to trigger the pressure switch to move, so as to control the pressure; a temperature sensor, which is additionally arranged, can be used for converting a measured temperature signal to an electric signal to control whether the heating disc is continually heated to control the pressure or not, so that the pressure limiting value is convenient to adjust.

Description

Technical field [0001] The invention relates to the technical field of electric pressure cookers, in particular to an electric pressure cooker with an adjustable pressure limit value. Background technique [0002] Electric pressure cooker is an upgraded product of traditional pressure cooker and rice cooker. It combines the advantages of pressure cooker and rice cooker, completely solves the safety problem of pressure cooker, and relieves the safety hazard of ordinary pressure cooker that has plagued consumers for many years. [0003] At present, the pressure switch added in the technology of adjusting the pressure limit value in the existing electric pressure cooker is mostly fixed, and the height of the pressure switch cannot be adjusted. Due to the different cooking ingredients, it is easy to be unable to control the ingredients for a long time. The phenomenon of burning occurs, and at the same time, one way is used to adjust the pressure limit value, which reduces the safety an...

AI Technical Summary

Problems solved by technology

[0003] At present, in the process of using the existing electric pressure cooker, most of the pressure switches added in the technology of adjusting the pressure limit value are fixed, and the height of the pressure switch cannot be adjusted. The phenomenon of overcooking occurs, and at the same time, most of them use one method to adjust the pressure limit value, which reduces the safety and convenience of pressure control

In addition, the existing electric pressure cooker usually adopts a sealing ring to realize the sealing between the pot cover and the pot body in the sealing design of the joint surface of the pot cover and the pot body. Due to long-term use, it will cause The sealing effect of the sealing ring becomes worse, which will easily lead to the phenomenon of pressure release in the electric pressure cooker, which reduces the safety of use, and it is not convenient for users to control the pressure limit value
