Problems solved by technology

But until now, due to the large size and high cost of nitrogen-generating equipment traditionally used for controlled atmosphere preservation, this technology has basically been limited to use in various large-scale professional storages (storage capacity is generally at least 30 tons or more).
It can be said that what kind of appropriate gas adjustment technology and corresponding devices can be used to economically miniaturize and quiet the air conditioning system, making it suitable for families or individual users, is a problem that technicians in the field of air conditioning and fresh-keeping have been eager to solve but have never been able to solve. Technical problems that can be successfully solved
[0005] In addition, the modified atmosphere fresh-keeping technology needs to use an air pump to extract oxygen, but the air pump is noisy

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 view of the air pump assembly shown after the seal box is removed from the mounting base, image 3 yes figure 1 An exploded schematic of the aspirator assembly shown. like Figure 1 to Figure 3 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 a mounting base 100 , a sealing box 200 and an air pump 300 . Wherein, the air suction pump 300 is arranged inside the sealed box 200 . When the suction pump 300 is running, the sealing box 200 can largely block the noise from spreading outward. The installation bottom plate 100 is used to support the sealing box 200 upw...

Abstract

The invention relates to an air pump assembly and a refrigerating and freezing device. The air pump assembly comprises a mounting plate, a seal box and an air pump. A backstop part extending upwards is arranged on the rear part of the upper surface of the mounting plate; the front surface of the backstop part is concaved backwards to form a positioning concave part; a positioning convex part protruding backwards is arranged on the rear part of the seal box; the seal box is located on the upper side of the mounting plate; the positioning convex part is clamped into the positioning concave part; the front part of the seal box is locked in the mounting plate; and the air pump is arranged in the seal box. The air pump assembly provided by the invention is low in running noise, and convenient to disassemble and assemble in the refrigerating and freezing device.

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...
