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

[0042] 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 The schematic diagram of the shown air pump assembly after the upper box body is flipped open; image 3 yes figure 1 An exploded schematic of the aspirator assembly shown. Such as Figure 1 to Figure 3As 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. The air pump assembly 10 includes a sealed box 200 defining a sealed space and an air pump 300 disposed inside the sealed box 200 . The sealed box 200 includes a lower box body 210 with an open upper side and an upper box body 220 with an open lower side. The upper box body 220 is sealed and buckled on the upper side of the lower box body 210 to jointly define a sealed space of th...

Abstract

The invention relates to an air extracting pump assembly and a refrigerating and freezing device. The air extracting pump assembly comprises a sealing box where a sealing space is defined, and an air extracting pump arranged in the sealing box. The sealing box comprises a lower box body with the upper side opened, and an upper box body with the lower side opened. A sealing cover of the sealing box is buckled on the upper side of the lower box body so that the sealing space of the sealing box can be defined by the sealing cover and the lower box body together. The rear end of the upper box body is hinged to the rear end of the lower box body. The front end of the upper box body is fastened at the front end of the lower box body in a thread connection manner. By means of the air extracting pump assembly, outward propagation of the noise of the air extracting pump can be reduced, and the air extracting pump is convenient to disassemble and assemble.

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...
