Abstract

The invention provides a vacuum fresh-keeping refrigerator pressure value control method, a refrigerator and a storage medium. The vacuum fresh-keeping pressure value control method comprises the steps of identifying the types of articles stored in a vacuum fresh-keeping drawer; acquiring an optimal storage pressure value corresponding to each type of articles, and calculating an optimal pressure value of the vacuum fresh-keeping drawer; starting a vacuum pump to vacuumize the vacuum fresh-keeping drawer; and shutting down the vacuum pump when detecting that the pressure value in the vacuum fresh-keeping drawer reaches the optimal pressure value. The method has the beneficial effects that the optimal pressure value in the vacuum fresh-keeping drawer is calculated according to the types of the articles stored in the vacuum fresh-keeping drawer, and the fresh-keeping effect is good.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a method for controlling the pressure value of a vacuum fresh-keeping refrigerator, a refrigerator and a storage medium. Background technique [0002] In order to improve the preservation effect and extend the preservation time of fresh items, a vacuum preservation area is added to the existing refrigerator, and an air extraction structure is set inside the refrigerator compartment, and after the airtight vacuum preservation box is placed in the refrigeration compartment, the The vacuum fresh-keeping box is pumped to increase the fresh-keeping time of the items. [0003] However, different types of items at different stages require different degrees of vacuum. The current vacuum fresh-keeping refrigerators pump air according to the set pressure value, and cannot automatically adjust the pressure value according to the stored items, and cannot achieve the best fresh-keeping effect. ...
