Electric pressure cooker capable of automatically switching pressure limiting values

Abstract

The invention discloses an electric pressure cooker capable of automatically switching pressure limiting values. When low-temperature food needs to be cooked, the pressure limiting value of a pressure limiting valve is manually set by a person; after the cooking is finished, the action of turning rotatably or moving a pot cover is carried out, the pressure limiting valve is driven to be recovered to the rated pressure limiting value from the set pressure limiting value, so that a consumer can automatically adjust the pressure limiting value of the pressure limiting valve during the processes of opening and closing the pot cover, and the pressure limiting valve is guaranteed to be at the rated pressure limiting value state all the time; the effective compatibility of high-temperature cooking and low-temperature cooking of the electric pressure cooker is achieved with lowest cost and simplest operation; the cooking time of the electric pressure cooker is enabled to the shortest, no boiling phenomenon occurs at high temperature, the energy-saving effect during cooking is good; and therefore, the electric pressure cooker is an all-round cooking champion and also is endowed with the new capacity as the low-temperature cooking champion.

Description

technical field [0001] The invention relates to the technical field of electric pressure cooker, in particular to an electric pressure cooker whose pressure limit value can be automatically switched from a pressure limit value to a rated pressure limit value with the rotation of the pot cover. Background technique [0002] Electric pressure cooker has developed extremely rapidly in recent years because of its realization of cooking automation, short cooking time, and significant energy-saving effect of non-boiling cooking. [0003] However, as the all-around cooking champion electric pressure cooker, because the working pressure has been set at the factory, no matter what kind of food is cooked, there is only one cooking temperature, and different foods require different cooking temperatures. Performance is far inferior to single-function cooking utensils, and this deficiency in cooking performance is particularly prominent in cooking performance. When cooking medium-sized ...

AI Technical Summary

Problems solved by technology

On this basis, it overcomes the inconvenience of using two pressure limiting valves, or the adjustable pressure limiting valve, the difficulty of storing the pressure limiting valve, and the cumbersome operation that must be manually adjusted before and after each cooking, effectively preventing consumers from forgetting to adjust the limit. After the pressure value is exceeded, the performance of high-temperature cooking will decrease, and the cooking liquid food will spill and splash, polluting the environment, and completely eradicate the electrical safety problems caused by the spill
