Gas suction pump assembly and cold storage and freezing device

Abstract

The invention relates to a gas suction pump assembly and a cold storage and freezing device. The gas suction pump assembly comprises an installing box and a gas suction pump; a containing space is defined in the installing box; at least part of the box wall of the installing box is made from a micro-porous silencing plate; the surface of the micro-porous silencing plate is provided with a plurality of silencing through holes; the gas suction pump is arranged in the installing box; and the micro-porous silencing plate is arranged to absorb noise generated by the gas suction pump when the gas suction pump runs. By means of the micro-porous silencing plate, the gas suction pump assembly reduces outward spreading of the noise when the gas suction pump runs.

Description

technical field

[0001] The invention relates to the technical field of refrigerator storage, in particular to an air suction pump assembly and a refrigerating and freezing device. Background technique

[0002] With the improvement of the quality of life, consumers have higher and higher requirements for food preservation in refrigeration and freezing devices such as refrigerators and freezers. Modified atmosphere preservation technology generally refers to the technology of prolonging the life of food storage by adjusting the gas atmosphere (gas composition ratio or gas pressure) in the closed space where the storage is located. The basic principle is: in a certain closed space A gas atmosphere different from normal air components is obtained through various adjustment methods to inhibit the physiological and biochemical processes and microbial activities that cause the storage (usually food) to deteriorate. In particular, in this application, the discussed modified atmosph...

Embodiment Construction

[0041] figure 1 is a structural schematic diagram of an air pump assembly according to an embodiment of the present invention; figure 2 yes figure 1 An exploded schematic of the aspirator assembly shown; image 3 It is a schematic diagram of the cooperative structure of the air pump and the lower box; Figure 4 It is a schematic diagram of the local structure of the microporous sound-absorbing plate. Such as Figure 1 to Figure 4 As shown, the present invention provides an air pump assembly 10, which can be used in refrigerators and other refrigerating and freezing devices for pumping out oxygen in a closed space to create a nitrogen-rich and oxygen-poor fresh air atmosphere.

[0042]The air pump assembly 10 may generally include an installation box 200 and an air pump 300 disposed inside the installation box 200 . Wherein, the interior of the installation box 200 defines an accommodating space for accommodating the air pump 300 . Moreover, at least part of the box wall...
