Pressure control device of micro-pressure electric cooker and micro-pressure electric cooker

Abstract

The invention relates to the technical field of electric cookers, in particular to a pressure control device of a micro-pressure electric cooker and the micro-pressure electric cooker. The pressure control device comprises an electromagnetic valve and an ejecting piece controlled by the electromagnetic valve, and further comprises a pressure control assembly. The pressure control assembly comprises a movable steel ball and a steel ball supporting base arranged on a cooker cover and used for supporting the steel ball. An exhaust hole is formed in the top of the steel ball supporting base. A concave site downwards indented, matched with the steel ball and used for placing the steel ball is arranged on the top end face of the steel ball supporting base. The exhaust hole is arranged at the bottom of a concave surface and communicated with the interior of a cooker body. A stop piece is arranged on the cooker cover. A gap for the steel ball to move is formed between the stop piece and the steel ball supporting base. When the electromagnetic valve is in a turned-off state, the ejecting piece ejects the steel ball so that the steel ball can be disengaged from the exhaust hole to abut against the stop piece. By arranging the pressure control device on the cooker cover of the electric cooker, the pressure in the cooker body can be effectively controlled, the electric cooker is convenientto uncover after cooking rice, there is no need to wait for the natural cooling of the cooker body, and waiting time is shortened.

Description

[0001] 【Technical field】 [0002] The present application relates to the technical field of electric rice cookers, in particular to a pressure control device for a micro-piezoelectric rice cooker and the micro-piezoelectric rice cooker. [0003] 【Background technique】 [0004] With the development of rice cooker technology, the control technology of rice cooker has also gone through several important stages, first is mechanical control, then electronic control, microcomputer control, and then the electromagnetic and micro-pressure rice cooker that will become the mainstream of the market. The micro-pressure rice cooker is popular in the market because of its soft cooking. The micro-pressure rice cooker will generate a certain pressure during the heating process. The lid cannot be opened immediately after cooking, and the body needs to be exhausted. After the body cools down naturally It takes a long time to open the lid, and the pressure in the body of the pot is constant when ...

AI Technical Summary

Problems solved by technology

The micro-pressure rice cooker is popular in the market because of its soft cooking. The micro-pressure rice cooker will generate a certain pressure during the heating process. The lid cannot be opened immediately after cooking. It is necessary to exhaust the body of the pot. It takes a long time to open the lid, and the pressure inside the cooker is constant when cooking, so intermittent exhaust cannot be realized, and it is difficult to ensure the taste of the food in the cooker, resulting in poor user experience
