The invention discloses a cooking utensil and a method for controlling freshness by vacuum reservation. The cooking utensil comprises: a pot body, the pot body has a cooking cavity with an open top; Installed to the pot body, the cover body has a suction port and an exhaust port; the vacuum device is located in the cover body and communicates with the suction port and the exhaust port respectively. The vacuum device vacuumizes the cooking cavity to make the cooking cavity A negative pressure vacuum is formed; the control device is used to obtain the reservation time corresponding to the vacuum reservation preservation instruction when the cooking appliance receives the vacuum reservation preservation instruction, and obtain the vacuum degree when the cooking appliance is reservation preservation according to the reservation time, and according to the obtained vacuum degree The vacuum device is controlled to work until the vacuum degree in the cooking cavity reaches the acquired vacuum degree, and the vacuum device is controlled to stop working, thereby ensuring the vacuum preservation effect.
Description
technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a cooking appliance and a control method for vacuum reservation fresh keeping of the cooking appliance. Background technique [0002] Cooking utensils (such as rice cookers) have a long-term reservation function (such as reservation cooking), when the cooking utensils enter the reservation stage, the cooking utensils are vacuumed and maintained for a long time, which can effectively prevent rice water or other ingredients from deteriorating and keep fresh Effect. [0003] In related technologies, regardless of the user's appointment time, freshness is kept at a constant vacuum degree, such as figure 1 shown. When the appointment time is too long, the fresh-keeping effect may be deteriorated with a constant vacuum; when the appointment time is short, the fresh-keeping effect is better with a constant vacuum value, but the vacuum system will be overused and the life of...
