Cooking utensil, control method and device of cooking utensil and computer readable storage medium

Abstract

The invention provides a cooking utensil, a control method and device of the cooking utensil and a computer readable storage medium. The control method comprises the following steps of S10, judging whether an instruction of entering a fresh-keeping mode is received or not; if yes, executing the step S20, and in the fresh-keeping stage, controlling an exhaust device to be turned off to ensure thata cooking cavity does not communicate with the outside; and if not, executing the step S30, and entering a conventional cooking mode. According to the control method, when cold air needs to be discharged, the exhaust device is controlled to be turned on, the cooking cavity communicates with the outside, and the cold air can be discharged, so that a float can be removed, the situation that the negative pressure cannot be generated because the cooking cavity cannot be sealed due to fallback of the cooled float is avoided, and the cost of the cooking utensil is reduced by removing the float. In the fresh-keeping stage, the exhaust device is controlled to be turned off, so that the cooking cavity is isolated from the outside and the cooking cavity is internally sealed; and as food materials and the air in the cooking cavity are cooled, the negative pressure is formed in the cooking cavity, and the preservation time of food is prolonged.

Description

technical field [0001] The present invention relates to the field of kitchen utensils, and more specifically, to a control method for cooking utensils, a control device, a cooking utensil, and a computer-readable storage medium. Background technique [0002] Negative pressure helps to prolong the storage time of food, so the negative pressure function can be developed on cooking utensils such as pressure cookers, but the existing pressure cookers have a float, which is in an open state under normal pressure, so that the pressure cooker cannot generate negative pressure. The pots of existing cooking utensils are made of single-layer or two-layer plates. Such pots have limitations in thermal conductivity, corrosion resistance, etc., and it is difficult to have multiple excellent performances at the same time. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] Therefore, the purpos...

Problems solved by technology

[0002] Negative pressure helps to prolong the preservation time of food, so the negative pressure function can be developed on cooking appliances such as pressure cookers, but existing pressure cookers have floats, which are open under normal pressure, so that pressure cookers cannot generate negative pressure

The pots of existing cooking utensils are made of single-layer or two-layer plates. Such pots have limitations in thermal conductivity and corrosion resistance, and it is difficult to have excellent performance in many aspects at the same time.
