Background technique
With the raising of quality of the life, consumer requires the food fresh keeping of the refrigeratings device such as refrigerator, refrigerator more next
It is higher.Controlled atmosphere technology generally refers to atmosphere (the gas componant ratio by adjusting enclosure space locating for storage object
Example or gas pressure) mode come come the technology that extends shelf life of food products, basic principle are as follows: in certain enclosure space
It is interior, the atmosphere different from normal air constituent is obtained by various regulative modes, to inhibit to cause storage object (usually to eat
Material) putrid and deteriorated physiological and biochemical procedure and microorganism activity.Particularly, in this application, the controlled atmosphere discussed will
Specifically in the controlled atmosphere technology that gas component ratio is adjusted.
Those skilled in the art know that normal air constituent includes (pressing volume percentage, hereafter together): about 78%
Nitrogen, about 21% oxygen, about 0.939% rare gas (helium, neon, argon, krypton, xenon, radon), 0.031% carbon dioxide, with
And 0.03% other gases and impurity (for example, ozone, nitric oxide, nitrogen dioxide, vapor etc..In controlled atmosphere field,
It generallys use and is filled with nitrogen-rich gas to enclosure space to reduce the mode of oxygen content and obtain the fresh-keeping gas atmosphere of rich nitrogen oxygen deprivation
It encloses.Here, those skilled in the art know, nitrogen-rich gas refers to that nitrogen content is more than nitrogen content in above-mentioned normal air
Gas, such as nitrogen content therein can be 95%~99%, even higher；And the fresh-keeping atmosphere of rich nitrogen oxygen deprivation refers to nitrogen
Gas content is lower than the gas atmosphere of oxygen content in above-mentioned normal air more than nitrogen content, oxygen content in above-mentioned normal air
It encloses.
Although the history of controlled atmosphere technology can be traced by 1821 German biologist and find fruit and vegetable in hypoxemia water
It usually can be reduced metabolism to start.But up to this point, since the equipment of making nitrogen volume for being conventionally used to controlled atmosphere is huge
Greatly, with high costs, cause the technology to be substantially also limited to using (the storage capacity one on the professional storage of various large sizes
As at least 30 tons or more).It can be said that being likely to economically using which kind of gas regulation technology appropriate and related device by controlled atmosphere
System compact, mute make it is suitable for family or personal user, are that controlled atmosphere field technical staff thirsts for solving always

It is cold.
Controlled atmosphere membrane module 30 has at least one controlled atmosphere film 31 and an oxygen rich gas collecting chamber, and its surrounding space and controlled atmosphere
Fresh-keeping space connection.The controlled atmosphere membrane module 30 may be arranged so that the oxygen in 30 surrounding space air-flow of controlled atmosphere membrane module relative to
Nitrogen in 30 surrounding space air-flow of controlled atmosphere membrane module more penetrates controlled atmosphere film 31 and enters oxygen rich gas collecting chamber.Specifically,
The inner surface of each controlled atmosphere film 31 is towards oxygen rich gas collecting chamber, to be less than controlled atmosphere film group in the pressure of oxygen rich gas collecting chamber
When the pressure of the surrounding space of part 30, make the oxygen in the air of the exterior space of controlled atmosphere membrane module 30 relative to nitrogen therein
More enter oxygen rich gas collecting chamber through at least one controlled atmosphere film 31.
Pumping pump assembly 10 may be disposed in compressor bin 13, and mounting leg 100 is mounted on compression by shock absorption footpad 400
On the bottom wall of cabin 13.The inlet end of aspiration pump 300 is connected to via pipeline 50 with the oxygen rich gas collecting chamber of controlled atmosphere membrane module 30,
The gas penetrated in oxygen rich gas collecting chamber to be pumped to outside container for storing.
In this embodiment, aspiration pump 300 is evacuated outward, and the pressure of oxygen rich gas collecting chamber can be made to be less than controlled atmosphere membrane module
The pressure of 30 surrounding space further can make the oxygen in 30 surrounding space of controlled atmosphere membrane module enter oxygen rich gas collection
Chamber.Since controlled atmosphere space is connected to 30 surrounding space of controlled atmosphere membrane module, the air in controlled atmosphere space can enter controlled atmosphere
30 surrounding space of membrane module, therefore the oxygen in the air in controlled atmosphere space can also be made to enter oxygen rich gas collecting chamber, from
And rich nitrogen oxygen deprivation is obtained in controlled atmosphere space in favor of the atmosphere of food fresh-keeping.
Refrigerating device of the invention can make to be formed rich nitrogen oxygen deprivation in controlled atmosphere space in favor of the gas of food fresh-keeping
Body atmosphere, the atmosphere reduce the intensity of fruit/vegetable aerobic breathing, simultaneously by the content of oxygen in reduction fruits and vegetables shelf space
The respiration for guaranteeing basis prevents fruits and vegetables from carrying out anaerobic respiration, to achieve the purpose that fruits and vegetables long-period freshness preserving.Moreover, the gas
Body atmosphere also has the gases such as a large amount of nitrogen, will not also reduce article in controlled atmosphere space by cold efficiency, fruits and vegetables can be made
Deng effectively being stored.Aspiration pump 300 is set in compressor bin 13, can be made full use of 13 space of compressor bin, not accounted for additionally
It with elsewhere, therefore not will increase the additional volumes of refrigerating device, the compact-sized of refrigerating device can be made.And
It is lower to rigidity, the intensity requirement of cabinet 80 etc., realize that requirement is very low, then cost is also very low.Refrigerating device of the invention
The above-mentioned technical problem that controlled atmosphere field technical staff thirsts for always solution but the solution that fails always is well solved.
Refrigerating device of the invention is not only small in size, but also noise is also very low, especially suitable for family and personal use.
In some embodiments of the invention, multiple micropores, storage space 201 and controlled atmosphere can be offered on drawer cylinder 20
Fresh-keeping space is via multiple microporous connectivities.Micropore is also referred to as air equalizer opening, and each micropore can be millimetre-sized micropore, example
If the diameter of each micropore is 0.1mm to 3mm, preferably 1mm, 1.5mm etc..Multiple micropores, which are arranged, can make in controlled atmosphere space
Pressure be unlikely to too low, the setting of multiple micropores will not make the nitrogen in controlled atmosphere space to big storage space 201
Flowing will not influence the preservation of food in controlled atmosphere space even if flowing is also that very little is even negligible.At this
In some alternative embodiments of invention, micropore can also be not provided on drawer cylinder 20, even if in this way, also having in controlled atmosphere space
With the presence of gases such as a large amount of nitrogen, user is when pulling the drawer out ontology 28, without too sweat, compared to existing vacuum
Material storage room, then can be significantly laborsaving.
In some embodiments of the invention, storage space 201 is refrigerating space, and storage temperature is generally at 2 DEG C to 10
It is preferably 3 DEG C to 8 DEG C between DEG C.Further, cabinet 80 can also limit reefer space 12 and alternating temperature space 27, and freezing is empty
Between 12 lower sections for being set to storage space 201, alternating temperature space 27 is set between reefer space 12 and refrigerating space.Reefer space
