Vacuum electric cooker capable of opening cover conveniently

Abstract

The invention discloses a vacuum electric cooker capable of opening a cover conveniently, and belongs to the field of kitchen household appliances. The problem that a cover of an existing vacuum electric cooker cannot be opened smoothly due to the negative pressure effect in the cover opening process is solved. The vacuum electric cooker comprises a cooker body, a cooker cover and an air extracting device; the cooker cover covers the cooker body to form a cooking cavity, the air extracting device is used for extracting air from the cooking cavity so as to make the cooking cavity form negativepressure, the cooker cover is provided with an air inlet valve, an air inlet drive assembly and a cover opening button, the air inlet drive assembly comprises a drive member and a retaining member, the cover opening button is pressed to switch on the air inlet valve, and the retaining member locks the drive member when the drive member opens the air inlet valve. According to the technical scheme,when the cover of the vacuum electric cooker is opened, the internal negative pressure state can be relieved, so that it is ensured that the cooker cover can be opened smoothly.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of kitchen appliances, in particular to a vacuum electric cooker which is convenient to open the cover. [0003] 【Background technique】 [0004] Vacuum negative pressure or freezing technology can enhance the freshness of food. This technology is applied to kitchen appliances, and rice cookers with vacuum function have been developed. Usually, a vacuum pump is set on the lid of the cooker, and the vacuum pump is used to pump air from the cooking space to make Negative pressure is formed in the cooking space, and the negative pressure state has the advantages of accelerating the water absorption of rice and enhancing the freshness of food. However, if the rice cooker still maintains a negative pressure state when the cooking is completed, the user presses the button to open the lid, and the lid may be under the action of negative pressure. Adsorbed on the pot body and cannot be opened normally. In the prior ar...

[0004] Vacuum negative pressure or freezing technology can enhance the freshness of food. This technology is applied to kitchen appliances, and rice cookers with vacuum function have been developed. Usually, a vacuum pump is set on the lid of the cooker, and the vacuum pump is used to pump air from the cooking space to make Negative pressure is formed in the cooking space, and the negative pressure state has the advantages of accelerating the water absorption of rice and enhancing the freshness of food. However, if the rice cooker still maintains a negative pressure state when the cooking is completed, the user presses the button to open the lid, and the lid may be under the action of negative pressure. Absorbed on the pot body and cannot be opened normally

In the prior art, a solenoid valve is usually installed on the lid to release the negative pressure state, but the cost of the solenoid valve is too high and it needs to rely on circuit control, so the reliability is not high
