Problems solved by technology

On the basis of retaining the existing characteristics and operation of the electric pressure cooker, it completely solves the difficulty of storing the existing pressure limiting valve with two pressure limiting valves and the use of the existing ordinary pressure cooker with adjustable pressure limiting value. The operation is cumbersome, and the pressure limiting valve is not easy to clean when it is dirty, resulting in steam leakage and other problems. At the same time, it can effectively improve and enhance the cooking performance of the electric pressure cooker.

Embodiment

[0026] as attached image 3 As shown, when the pressure regulating button (6) is not adjusted, the elastic member (5) is not supported by the push plate (4), and the elastic member (5) and the gravity valve body set on the exhaust pipe (2) (3) No compression deformation occurs. At this time, the sealing pressure of the gravity valve body (3) on the upper port of the exhaust pipe (2) is the largest, and the pressure limiting value produced by the pressure limiting valve (30) is also the largest.

[0027] as attached Figure 4 As shown, when the pressure regulating button (6) is adjusted, the push plate (4) will lift the elastic piece (5). The gravity valve body (3) on the pipe (2) increases the compression deformation produced by the elastic member (5), and the deformed elastic member (5) produces an equal amount of elastic force, which will change the sealing and exhaust of the gravity valve body (3). The pressure at the upper port of the pipe (2), the pressure limiting valu...

Abstract

The invention discloses an electric pressure cooker with adjustable pressure limiting values. According to the Hooke's law of elasticity mechanics, and based on structures of pressure limiting valves and production and assembly of existing electric pressure cookers, a pressure adjusting knob (6) is adjusted, so that an elastic part (5) is compressed and deformed, the pressure of the upper end port of a sealing exhaust pipe (2) of a gravity valve body (3) is changed, adjustment of the pressure limiting values of the electric pressure cooker is achieved and the cooking performance of the electric pressure cooker is improved with the smallest change, the lowest cost, the simplest operation and the most reliable structure on the basis that characteristics and operation of existing electric pressure cookers are reserved.

Description

technical field [0001] The invention relates to the technical field of electric pressure cooker, in particular to an electric pressure cooker which uses a valve body of a gravity pressure limiting valve and whose pressure limit value can be adjusted under the action of an elastic element. Background technique [0002] Electric pressure cooker has developed rapidly in the past ten years because of its strong cooking automation performance, short cooking time, and remarkable energy-saving effect of non-boiling cooking. [0003] High cooking temperature, single cooking temperature, automatic cooking control, no boiling in cooking, no overflow of cooking liquid food, etc. are the characteristics of electric pressure cooker. In order to maintain these characteristics of the electric pressure cooker, for ten years, as the pressure limiting valve of the electric pressure cooker to quickly open the cover to exhaust and relieve pressure, and as an important safety guarantee, the grav...
