Problems solved by technology

This fresh-keeping method has the following limitations: 1. Since the vacuum pumping process needs to be realized by a vacuum pump, the vacuum pump will occupy part of the storage space in the refrigerator room; 2. This fresh-keeping method needs to seal the drawer, otherwise the drawer cannot form a vacuum state. Therefore, higher requirements are put forward for the forming and assembly process of the drawer; 3. The drawer is an inherent part of the refrigerator, and the drawer cannot be taken out from the refrigerator and carried at will, which is not convenient for the handling and use of vacuum preservation items

Abstract

The invention discloses a refrigerator. The refrigerator comprises a storage room, a door body, a fresh-keeping box and a vacuum pumping assembly. The fresh-keeping box is provided with a storage cavity, the fresh-keeping box is provided with a vacuum pumping interface part, and the fresh-keeping box is connected with the door body. The vacuum pumping assembly includes a vacuum pump, a vacuum pumping pipeline, and a vacuum pumping joint assembly, and the vacuum pumping pipeline connects the vacuum pump with the vacuum pumping joint assembly. When the vacuum pumping joint assembly is connectedto the vacuum pumping interface part, the vacuum pumping assembly can vacuumize the storage cavity. The vacuum pumping joint assembly comprises an upper cover body and a lower cover body; an air flowchannel is formed between the upper cover body and the lower cover body; the vacuum pumping pipeline is connected to the upper cover body or the lower cover body and communicates with the air flow channel; and the lower cover body can be connected to the vacuum pumping interface part to communicate the air flow channel with the storage cavity. The vacuum pumping joint assembly is of a structure that the upper part and the lower part are detachable, so that parts such as the pipeline are convenient to mount.

Description

Technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator with a vacuum preservation device. Background technique [0002] In recent years, people’s health awareness has gradually increased, and the demand for food preservation has also increased. Refrigerators are the most commonly used household appliances for food storage. Food preservation and storage has become an urgent technical requirement in the refrigerator field. [0003] At present, various manufacturers have introduced different preservation technologies in response to the problem of food preservation and storage. For example, in the vacuum preservation technology, the conditions of food deterioration under vacuum conditions have changed. First of all, it is difficult for microorganisms and various promoting enzymes to survive in a vacuum environment, and it takes a long time to meet the requirements of microbial growth; secondly, in a vacuum state,...
