Abstract

The invention discloses a refrigerator and a control method of a vacuum drawer of the refrigerator, a first vacuum pump and a second vacuum pump are arranged in the vacuum drawer, the vacuum drawer is vacuumized through the two pumps, the vacuumizing time is shortened, and the vacuum drawer can quickly enter a vacuum environment. During vacuumizing, firstly, the double pumps are controlled to be started at the same time according to preset initial power, then in the operation process of the double pumps, in order to avoid the problem of too large noise, the operation states of the first vacuum pump and the second vacuum pump are controlled according to the air pressure difference stage of the standard atmospheric pressure and the real-time atmospheric pressure, and the operation power of the first vacuum pump and the operation power of the second vacuum pump are adjusted. And the double pumps stop working until the vacuum drawer enters a pressure maintaining state, so that the noise is reduced as much as possible while the vacuumizing time is shortened. According to the embodiment of the invention, the vacuum drawer is vacuumized by adopting the double vacuum pumps, the vacuumizing time is shortened, meanwhile, the working power of the double vacuum pumps is adjusted by stages, and the continuous high noise phenomenon caused by long-time high-power working of the double vacuum pumps is avoided.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a control method of a refrigerator and a vacuum drawer thereof. Background technique [0002] As an indispensable electrical product in home life, refrigerators occupy an important market share. With the improvement of consumers' requirements for the quality of fresh food, the requirements for refrigerators are also getting higher and higher, requiring refrigerators to have higher configuration and more powerful functions, especially hope that the stored fresh food can have better quality. Long storage period to ensure the freshness of the ingredients and prevent the loss of nutrients. In order to better store food, Hisense has launched all-ecological, all-scenario vacuum refrigerators, including refrigerators with vacuum drawers, door-evacuated refrigerators, door-shelf evacuated refrigerators, and door-in-door vacuum box refrigerators. The vacuum fresh-keeping refrigera...
