The negative pressure generating means is used to make the pressure in the cooking space lower than a predetermined pressure. The pressure in the cooking space may be brought to below atmospheric pressure, for example by evacuating the cooking space. A state in which the pressure inside the cooking space is lower than the atmospheric pressure may be referred to as a negative pressure state. Therefore, the cooking appliance 100 of the present invention may be an electric cooker, an electric pressure cooker, or the like having a negative pressure function. The negative pressure environment helps to optimize the cooking process and preserve the food. For example, when rice is cooked, the cooking space is kept in a negative pressure environment during the rice grains absorb water, so that the rice and the water can be mixed more quickly and better. In addition, the food which is not needed to be taken is stored in the cooking space in the negative pressure environment after the cooking is finished, so that the food deterioration speed can be reduced, and the food can keep good taste for a long time.

The negative pressure generating device comprises an air pump, an air inlet of the air pump is communicated with the channel through an exhaust tube made of silica gel, and an air outlet of the air pump is communicated with the external environment of the cooking space, for example, the external atmosphere. When a negative pressure environment is required to be formed in the cooking space, the air pump is started to pump air by operating the corresponding key on the cooking appliance, air in the cooking space is exhausted through the air exhaust pipe and the air pump, and the pressure in the cooking space is reduced accordingly. Pressure measuring devices can be arranged to monitor the pressure in the cooking space, when the pressure in the cooking space is reduced to a preset value, the air pump stops working, and a negative pressure environment is formed in the cooking space.

According to the utility model discloses a cooking utensil, through setting up the pressure release air current and changing to the structure, this pressure release air current changes to the structure and can change the flow direction of the gas that flows into in the culinary art space by the external world for these gas side directions flow into in the culinary art space, thereby avoid this gas to influence the roughness on food upper portion in the culinary art space, perhaps avoid food to splash on the lateral wall of interior pot or removable lid subassembly, can improve user and use experience.
