Refrigerator

Abstract

The invention discloses a refrigerator, relates to the technical field of storage equipment, and aims at solving the problems that a vacuum pump of an existing refrigerator is complex in damping structure and not ideal in damping effect. The refrigerator comprises a refrigerator body, a mounting box, a damping sleeve and the vacuum pump; a storage chamber is arranged inside the refrigerator body;the mounting box is fixed in the storage chamber, and a mounting cavity is formed inside the mounting box; the damping sleeve is arranged in the mounting cavity, and the outer wall of the damping sleeve abuts against the inner wall of the mounting cavity; the vacuum pump is arranged in the damping sleeve, and the inner wall of the damping sleeve is tightly attached to the outer wall of the vacuumpump. The refrigerator is used for storing food materials.

Description

technical field [0001] The invention relates to the technical field of storage equipment, in particular to a refrigerator. Background technique [0002] Refrigerator is a kind of storage equipment that keeps low temperature. By keeping food or other items in a constant low temperature and cold state to avoid spoilage, it is an indispensable storage equipment in people's daily life. In order to improve the fresh-keeping performance of the refrigerator, a refrigerator with a vacuum pump installed inside has appeared in the prior art. The storage room of the refrigerator is vacuumed through the vacuum pump to form a vacuum space in the storage room. Because the air is scarce under vacuum conditions, microorganisms do not have the conditions for survival. , It can prevent the stored food from spoiling, so as to achieve a better food preservation effect. However, when the vacuum pump is working, it will generate severe vibration, resulting in relatively large noise, which will a...

Problems solved by technology

[0004] However, the above-mentioned vacuum pump is provided with a three-layer sealed shell structure outside the pump body 1, and a vibration-damping structure is arranged between every two layers of sealed shells. The large space inside the room reduces the effective use space in the storage room, and when the pump body 1 vibrates, it will drive the first sealing shell to vibrate together, because the shock-absorbing limit column 6 is arranged under the first sealing shell Between the bottom surface of the cover 4 and the bottom of the third sealed case lower cover 7, therefore, when the first sealed case vibrates, the shock-absorbing limit post 6 can only absorb the direction of the first sealed case towards the bottom of the third sealed case The vibration of the first sealed shell cannot absorb the vibration of the first sealed shell in other directions, that is, it cannot prevent the outer wall of the first sealed shell except the bottom surface from colliding with the inner wall of the third sealed shell except the bottom surface when the first sealed shell vibrates, resulting in shock absorption Unsatisfactory effect
