Problems solved by technology

[0002] In the fresh-keeping technology of the refrigerator, oxygen is closely related to the oxidation and respiration of the food in the refrigerator. The slower the respiration of the food, the lower the oxidation and the longer the fresh-keeping time. Reducing the oxygen content in the storage space is beneficial to Food preservation has an obvious effect. Therefore, refrigerators with vacuum preservation function are becoming more and more mainstream. Vacuum preservation refrigerators place a vacuum box, vacuum tube and vacuum pump on the refrigerator, and the vacuum pump pumps the vacuum box to a vacuum state through the vacuum tube. Now In some vacuum fresh-keeping refrigerators, the vacuum pump is usually installed in the refrigerator case, placed in the same space as the heat exchanger of the refrigerator, and the vacuum box is placed in the low-temperature storage space of the refrigerator. On the one hand, the vacuum box occupies a part of the available volume of the refrigerator. On the other hand, the wiring of the vacuum tube connecting the vacuum box and the vacuum pump is complicated and inconvenient to repair. Therefore, the R&D personnel designed a new installation method of the vacuum pump, setting a storage space on the top of the door of the refrigerator, and setting the vacuum pump in the storage space. , the vacuum box is set on the door body, which solves the above-mentioned problem that the vacuum pump and the vacuum box occupy the volume space of the refrigerator. At the same time, the vacuum tube is also arranged inside the door body, and the wiring is simple. The space is too narrow, the vacuum pump vibrates during the working process and collides with the inner wall of the installation space to generate noise, and the existing shock absorbing and shock absorbing devices are not enough to play an effective role in this narrow space, and the noise control effect is not ideal

Abstract

The invention relates to the technical field of refrigerator preservation, and discloses a refrigerator which comprises a low-temperature storage chamber, a door body for opening or closing the storage chamber, a vacuum pump, a vacuum pipe, a vacuum box and a cushioning sleeve; the door body is internally provided with a mounting cavity for placing elements of all parts, and the vacuum pump is arranged in the mounting cavity; the vacuum pump is communicated with the vacuum box through the vacuum pipe; and the cushioning sleeve is arranged on the vacuum pump in a sleeving mode, and the cushioning sleeve is made of elastic materials and is of a corrugated barrel-shaped structure. The cushioning sleeve is arranged outside the vacuum pump, and vibration in the operation process of the vacuum pump is reduced through the cushioning performance of the elastic materials; because the space in the mounting cavity of the door body is relatively narrow, and a conventional cushioning sleeve uses a quite thick cushioning layer and cannot meet the use condition of the cushioning sleeve, so that the shape of a silicone rubber material is reasonably designed, the cushioning sleeve is arranged to be in an externally convex and internally concave corrugated shape, and vibration can be restrained to the maximum extent in a minimum space by utilizing the structural property.
