Electric pressure cooker

Abstract

The invention provides an electric pressure cooker which comprises a control circuit, a cooker, an upper lid, a lid, a pressure limiting valve and a driving component. The upper lid is positioned on the upper side of the cooker and is mounted on the cooker in such a manner that the upper lid can be opened and closed; the lid is positioned between the upper lid and the cooker, is rotatably mounted on the upper lid and is rotationally fastened and connected with the cooker; a through hole is formed in the upper lid, an exhaust pipe on the lid extends out of the through hole, and the pressure limiting valve sleeves the exhaust pipe; the driving component is positioned on a side of the exhaust pipe, is mounted on the upper lid and is electrically connected with the control circuit; a slip lift structure is arranged between the pressure limiting valve and the lid, and a matching portion is arranged on the pressure limiting valve. Compared with the traditional electric pressure cooker, the electric pressure cooker has the advantages that the lid is easy to open and close, the problem of difficulty in closing an existing lid due to the fact that internal pressures of an existing electric pressure cooker are higher than external pressures can be solved, and problems of cooker sucking and difficulty in opening the existing lid due to the fact that the internal pressures of the existing electric pressure cooker are lower than the external pressures also can be solved, and the electric pressure cooker can have functions of automatically exhausting air and releasing pressures in cooking procedures.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, to an electric pressure cooker. Background technique [0002] Due to the advantages of good cooking effect, fast cooking and energy saving, electric pressure cookers have entered thousands of households and become one of the necessary kitchen appliances. The pot cover of the rotatable pot cover type square pressure cooker is provided with pot teeth, because of its good appearance and simple structure, it has gradually become the leading product in the market. But this type of electric pressure cooker also has two disadvantages of general electric pressure cookers: [0003] 1. Difficult to close the lid in a hot state: When the lid is closed in a hot state, the float floats up under the pressure generated by the rapid expansion of the air in the pot, the air in the pot is sealed, and the air continues to expand under the residual heat in the pot to form a certain pressur...

Problems solved by technology

[0005] Analyzing the two technical problems in the related art, it can be concluded that the main reason for these two problems is that there is a large pressure difference between the inside of the electric pressure cooker and the outside, which can be solved perfectly as long as the pressure difference is reduced. In the related art, it is difficult to op
