Abstract

The embodiment of the invention provides a refrigerator. A refrigeration system, a vacuum pump, a storage space and a controller are arranged in the refrigerator. A vacuum chamber is arranged in the storage space. The controller is arranged in the manner that after the vacuum pump is started, the vacuum degree in the vacuum chamber is obtained; if the obtained vacuum degree reaches the first vacuum degree threshold value, the vacuum pump is controlled to be closed; after the vacuum pump is closed, the refrigeration system is controlled to be started to refrigerate the storage space; and if thetemperature of the refrigerated storage space meets the set temperature requirement, the refrigeration system is controlled to be stopped. The controller conducts control according to the process, and noise of the refrigerator is effectively lowered.

Description

technical field [0001] The present application relates to the technical field of refrigerators, in particular, to a refrigerator. Background technique [0002] With the improvement of people's requirements for food preservation, vacuum preservation technology is applied to refrigerators, so that refrigerators have a vacuum preservation function. Specifically, a vacuum pump and a vacuum chamber are introduced into the refrigerator, and the vacuum chamber is evacuated by the vacuum pump. So that the vacuum degree in the vacuum chamber requires the vacuum preservation requirements of the food. [0003] However, the existing refrigerator with vacuum preservation function has the problem of high noise during operation. Therefore, how to reduce the noise of the refrigerator is a technical problem to be solved urgently in the prior art. Contents of the invention [0004] Embodiments of the present application provide a refrigerator, which can reduce the noise of the refrigerato...
