Easy-to-open vacuum rice cooker

Abstract

The invention discloses a vacuum rice cooker which is convenient to open the cover, which belongs to the field of kitchen appliances and solves the problem that the cover of the existing vacuum rice cooker cannot be opened smoothly due to negative pressure when the cover is opened. The vacuum rice cooker of the present invention includes a cooking body , a pot cover and an air extraction device, the pot cover is closed on the pot body to form a cooking chamber, and the air extraction device is used to extract gas from the cooking chamber so that the cooking chamber forms a negative pressure, so The lid of the pot is provided with an air intake valve, an air intake drive assembly, and a cover opening button. The air intake drive assembly includes a drive part and a backstop. valve, the backstop locks the driver when the driver opens the intake valve. The technical scheme of the invention enables the vacuum electric cooker to reliably release the internal negative pressure state when the cover is opened, so as to ensure that the cover can be opened smoothly.

Description

【Technical field】 [0001] The invention relates to the field of kitchen appliances, in particular to a vacuum electric cooker which is convenient to open the cover. 【Background technique】 [0002] 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 art, a solenoid v...

Problems solved by technology

[0002] 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
