Multi-segmented pressure regulating electric pressure cooking saucepan

Abstract

The invention relates to a multi-segmented pressure regulating electric pressure cooking saucepan, which comprises a pan cover, a pan body, an electric heating device and a control circuit. The pan cover is provided with a multi-segmented pressure regulating device which comprises a pressure setting device, a pressure conversion device and a shell; the pressure conversion device comprises a pressure transmission mechanism, a displacement jumping mechanism and a signal transmission mechanism; the pressure transmission mechanism comprises a pneumatic piece and a steam sealing sleeve; the displacement jumping mechanism comprises a jumping slide block and a connecting rod which are in movable connection; a jumping spring is arranged between the jumping slide block and the pneumatic piece; a positioning mechanism is arranged between the jumping slide block and the shell; the pneumatic piece is provided with a touch piece which enables the jumping slide block to act; and the signal transmission mechanism comprises a switch component which is electrically connected with the control circuit. The multi-segmented pressure regulating electric pressure cooking saucepan has the advantages of accurate and reliable pressure regulation and realization of multi-segmented pressure regulation.

Description

Technical field [0001] The invention relates to a pressure cooking appliance, in particular to an electric pressure cooker capable of multi-stage pressure adjustment. Background technique [0002] The electric pressure cooker is a cooking appliance that works under high pressure. In order to ensure the safety of the electric pressure cooker, the prior art controls the pressure in the electric pressure cooker so that the pressure in the electric pressure cooker does not exceed the safe pressure value. How to convert the steam pressure signal in the pot into the corresponding mechanical signal and / or electrical signal, and then complete the feedback control of the pressure in the pot by the relevant mechanical device or electronic circuit, is one of the key links in achieving the pressure control of the electric pressure cooker. One. [0003] The pressure conversion device of the traditional electric pressure cooker, such as the Chinese utility model patent named "Fully-sealed autom...

Problems solved by technology

The disadvantage of this control method is that the mechanical amplification factor of the seesaw lever mechanism is not stable enough, so that the displacement variation of the sealed pressure valve cannot be stably and accurately transmitted to the magnet, resulting in a large control error, and there is only one pressure control point, can not meet the cooking requirements of a variety of food

[0006] Although this pressure conversion device solves some of the defects of the prior art to a certain extent, there are also major technical defects in the application process of this technical solution: during the pressure rise process in the pot, the pressure transmission device drives the rotating parts to continuously Rotation, the magnet on the rotating part is close to or facing the sensing element on the pot body, which may cause the sensing element to operate, which is prone to misoperation, and the pressure cannot be accurately controlled. The error is large, and the cooking pressure cannot be manually adjusted. , consumers cannot choose the corresponding food cooking pressure according to their own needs to meet the cooking requirements of food
