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 schematic of the aspirator assembly shown; image 3 yes figure 1 A schematic diagram of the cooperative structure of the upper box frame and the lower box frame of the air pump assembly shown. Such as 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. The suction pump assembly 10 includes defining a sealed box 200 and a suction 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 so as to joint...

Abstract

An air pump assembly (10) and a refrigeration device. The air pump assembly (10) comprises: a seal box (200) comprising a lower box body (210) with an opened upper side, and an upper box body (220) with an opened lower side, the upper box body (220) tightly covering the upper side of the lower box body (210) to define a sealed space with the lower box body (210); an air pump (300) provided in the sealed space of the seal box (200), an air inlet pipe (301) and an air outlet pipe (302) of the air pump (300) both extending upwards; and an air inlet connecting pipe (310) and an air outlet connecting pipe (320) embedded in the upper box body (220) and both extending in the up-down direction, the air inlet connecting pipe (310) being located above the air inlet pipe (301) and sleeved on the air inlet pipe (301), and the air outlet connecting pipe (320) being located above the air outlet pipe (302) and sleeved on the air outlet pipe (302). The air pump assembly (10) can reduce outward propagation of noise in operation of the air pump (300), and can facilitate dismounting the upper box body (220) onto the lower box body (210).

Description

technical field [0001] The invention relates to the technical field of refrigerator storage, in particular to a refrigeration 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 atmosphere fresh-keeping will be specifi...
