Another aspect of the present invention provides a kind of refrigerating device.Fig. 5 is cold preservation according to an embodiment of the invention
The schematic local structural graph of refrigerating plant；Fig. 6 is the schematic diagram at another visual angle of structure shown in Fig. 5；Fig. 7 is basis
The schematic local structural graph of the refrigerating device of one embodiment of the invention；Fig. 8 is the schematic exploded of structure shown in Fig. 7
Figure；Fig. 9 is the exploded view of controlled atmosphere membrane module in refrigerating device according to an embodiment of the invention.As Fig. 5 to Fig. 9 institute
Show, the refrigerating device of the embodiment of the present invention may include casing 80, door body, controlled atmosphere membrane module 30, aforesaid pumping pump group part
10 and refrigeration system.
Storage space 201 and compressor bin 13 are defined in casing 80.Door body is used to open or close storage space 201.
Further, it is provided with storage space 201 in container for storing, container for storing and there is controlled atmosphere space.Controlled atmosphere space
Can be hermetic type space or approximate hermetic type space.Preferably, container for storing is drawer appliance.Container for storing may include drawer cylinder
Body 20 and drawer body 28.Drawer cylinder 20 can have front to opening, and be arranged in storage space 201, specifically may be disposed at
The bottom of storage space 201.As one skilled in the art will recognize that, drawer cylinder 20 is may also set up in storage space 201
Middle part or top.Drawer body 28 is slidably disposed in drawer cylinder 20, with can from the forward direction opening of drawer cylinder 20
Operatively outwards extract out and be inwardly inserted into drawer cylinder 20.Drawer body 28 can have drawer end cap, and drawer end cap can be with drawer
The opening of cylinder 20 is engaged, to carry out the closed of controlled atmosphere space.In some substituting enforcement embodiments, container for storing
May include cylinder and be configured to open or close the little door body of cylinder.
Refrigeration system can be the cooling cycle system being made up of compressor, condenser, throttling arrangement and vaporizer etc..Compression
Machine is mountable in compressor bin 13.Vaporizer is configured to directly or indirectly provide cold into storage space 201.For example when
When the refrigerating device is domestic compression direct cooling refrigerator, vaporizer may be disposed at the inner side of casing 80.When the refrigerating
When device is domestic compression wind cooling refrigerator, also there is in casing 80 evaporator room, evaporator room passes through air path system and storing
Space 201 connects, and vaporizer is arranged in evaporator room, and exit is provided with blower fan, to be circulated system to storage space 201
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 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 enters oxygen rich gas collecting chamber through controlled atmosphere film 31.Specifically,
The inner surface of each controlled atmosphere film 31 is less than controlled atmosphere film group with the pressure in oxygen rich gas collecting chamber towards oxygen rich gas collecting chamber
During the pressure of the surrounding space of part 30, make controlled atmosphere membrane module 30 space outerpace air in oxygen relative to nitrogen therein
More oxygen rich gas collecting chamber is entered through at least one controlled atmosphere film 31.
Pumping pump group part 10 is may be disposed in compressor bin 13, and mounting leg 100 is arranged on compression by shock absorption footpad 400
On the diapire of cabin 13.The inlet end of air pump 300 is connected with the oxygen rich gas collecting chamber of controlled atmosphere membrane module 30 via pipeline 50,
So that the gas for penetrating oxygen rich gas collection intracavity is pumped to outside container for storing.
In this embodiment, air pump 300 is outwards evacuated, 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 be such that the oxygen in 30 surrounding space of controlled atmosphere membrane module collects into oxygen rich gas
Chamber.As controlled atmosphere space is connected with 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 can also make the oxygen in the air in controlled atmosphere space enter oxygen rich gas collecting chamber, from
And the atmosphere that rich nitrogen oxygen deprivation is beneficial to food fresh-keeping is obtained in controlled atmosphere space.
The refrigerating device of the present invention can make the gas that rich nitrogen oxygen deprivation is beneficial to food fresh-keeping is formed in controlled atmosphere space
Body atmosphere, the atmosphere reduce the intensity of fruit/vegetable aerobic breathing by the content of oxygen in reduction fruit and vegerable shelf space, while
Ensure the Repiration on basis, prevent fruit and vegerable from carrying out anaerobic respiration, so as to reach the purpose of fruit and vegerable long-period freshness preserving.And, the gas
Body atmosphere also has the gas such as substantial amounts of nitrogen, will not also reduce article in controlled atmosphere space by cold efficiency, fruit and vegerable can be made
Stored Deng effectively.Air pump 300 is arranged in compressor bin 13, can be made full use of 13 space of compressor bin, additionally not accounted for
With elsewhere, therefore the additional volumes of refrigerating device will not be increased, the compact conformation of refrigerating device can be made.And
It is relatively low to the rigid of 80 grade of casing, intensity requirement, realize that requirement is very low, then cost is also very low.The refrigerating device of the present invention
The above-mentioned technical barrier that controlled atmosphere art personnel thirst for solution but the solution that fails all the time always is solved well.
The refrigerating device not only small volume of the present invention, and noise is also very low, is particularly well-suited to 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, each micropore can be millimetre-sized micropore, example
Such as a diameter of 0.1mm to 3mm of each micropore, preferably 1mm, 1.5mm etc..Arranging multiple micropores can make in controlled atmosphere space
Pressure be unlikely to too low, the setting of multiple micropores will not also make the nitrogen in controlled atmosphere space to big storage space 201
Flowing, even if flowing is also that very little is even negligible, does not interfere with the preservation of food in controlled atmosphere space.At this
In some alternative embodiments of invention, micropore on drawer cylinder 20, can be also not provided with, even if so, controlled atmosphere also has in space
With the presence of gases such as substantial amounts of nitrogen, user when body 28 is pulled the drawer out, 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 its storage temperature is typically at 2 DEG C to 10
Between DEG C, 3 DEG C are preferably to 8 DEG C.Further, casing 80 can also limit reefer space 12 and alternating temperature space 27, and freezing is empty
Between 12 lower sections for being arranged at storage space 201, alternating temperature space 27 is arranged between reefer space 12 and refrigerating space.Reefer space
