Refrigerator

Abstract

The invention discloses a refrigerator, which comprises a box body, door bodies, a fresh-keeping box and a vacuumizing assembly. A storage chamber is formed in the box body, and a compressor bin is arranged at the bottom of the box body. The box body and the door bodies are hinged through hinges, and the hinges are provided with hinge shaft holes. A storage cavity is formed in the fresh-keeping box, and the fresh-keeping box is connected with one of the door bodies. The vacuumizing assembly comprises a vacuum pump, a vacuumizing pipeline and a vacuumizing joint assembly, the vacuumizing pipeline enables the vacuum pump and the vacuumizing joint assembly to communicate, and when the vacuumizing joint assembly communicates with the storage cavity, the vacuumizing assembly can vacuumize the storage cavity. The vacuum pump is arranged in the compressor bin, the vacuumizing joint assembly is arranged on the inner side of one of the door bodies, and the vacuumizing pipeline guided out from the vacuumizing joint assembly sequentially passes through a foaming layer of one of the door bodies, the hinge shaft holes and a foaming layer of the box body to the vacuum pump. The vacuum pump is placed in the compressor bin and does not additionally occupy the refrigeration space. The vacuumizing pipeline is hidden, and the structure is more compact.

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, and food preservation and storage has become an urgent technical demand in the refrigerator field. [0003] At present, various manufacturers have introduced different fresh-keeping technologies for the preservation and storage of food materials. For example, vacuum preservation technology, under the vacuum state, the conditions for food deterioration have changed. First of all, in a vacuum environment, microorganisms and various promoting enzymes are difficult to survive, and it takes a long time to meet the requirements of microbial growth; secondly, in a vacuum state, the oxygen i...

AI Technical Summary

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
