Description
Technical field
The present invention relates to refrigerator storing technical field, more particularly to a kind of refrigerating device.
Background technology
Refrigerator is to maintain a kind of refrigeration plant of constant low temperature, is also that one kind makes food or other articles keep constant low temperature
The product for civilian use of cold conditions.With the raising of quality of the life, consumer to storing the fresh-keeping requirement of food also more and more higher, especially
It is the requirement also more and more higher of the color and luster to food, mouthfeel etc..Therefore, the food of storage should also be as ensureing during storing, to eat
Color and luster, mouthfeel, freshness of thing etc. keep as far as possible constant.In the market in order to preferably store food, only very
Empty fresh-keeping one kind.Jing frequently with vacuum freshness retaining mode be that vacuum bag is fresh-keeping and vacuum storing compartment is fresh-keeping.
Fresh-keeping using vacuum bag, consumer stores every time food and is required for carrying out vacuumizing action, and troublesome poeration cannot
Consumer's likes.
It is fresh-keeping using vacuum storing compartment, because casing etc. is rigid structure, vacuum state is kept, to pumped vacuum systems
Requirement it is very high, the sealing property of refrigerator is required very high, often pick and place an article, the new air poured into is more, and energy is disappeared
Consumption is larger.And, under vacuum environment, food reception cold is relatively difficult, is particularly disadvantageous for the storage of food.Further, since being
Vacuum environment, user opens every time refrigerator doors etc. needs the very big strength of expense, causes user to use inconvenience.Although some refrigerators can
By pumped vacuum systems to indoor ventilation between vacuum storing, but user can be so caused to wait long period, poor in timeliness.Very
It is longer between space-time, will also result in the deformation such as refrigerator body seriously, i.e., the existing refrigerator with Vacuuming structure can not be well
Vacuum freshness retaining is completed, needs the intensity of casing etc. very big, realize that requirement is very high, cost is very high.
Additionally, inventor has found：Because the equipment of making nitrogen for being conventionally used to controlled atmosphere is bulky, with high costs, lead
Cause the technology be substantially also limited to using on various large-scale professional storages (typically at least 30 tons of storage capacity with
On).It can be said that using which kind of appropriate gas regulation technology and related device be only possible to economically by Air-conditioning system miniaturization,
Mute so as to suitable for family or personal user, is that controlled atmosphere art personnel thirst for always solving but failing all the time
The technical barrier for successfully solving.
The content of the invention

The pressure of 30 surrounding space, further, can be such that the oxygen in the surrounding space of controlled atmosphere membrane module 30 collects into oxygen rich gas
Chamber.Because controlled atmosphere space connects with the surrounding space of controlled atmosphere membrane module 30, the air in controlled atmosphere space can enter controlled atmosphere
The surrounding space of membrane module 30, 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 to form the gas that rich nitrogen oxygen deprivation is beneficial to food fresh-keeping in controlled atmosphere space
Body atmosphere, the atmosphere reduces the intensity of fruit/vegetable aerobic breathing by the content of oxygen in reduction fruits and vegetables shelf space, while
Ensure the respiration on basis, prevent fruits and vegetables from carrying out anaerobic respiration, so as to reach the purpose of fruits and vegetables 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, fruits and vegetables can be made
Stored Deng effectively.And it is relatively low to the rigid of casing 20 etc., intensity requirement, realize that requirement is very low, then cost is also very low.This
The refrigerating device of invention solves well controlled atmosphere art personnel to be thirsted for always solving but failing all the time
The above-mentioned technical barrier for solving.The refrigerating device not only small volume of the present invention, and noise is also very low, is particularly well-suited to house
Front yard and personal use.
In some embodiments of the invention, multiple micropores, storage space 211 and controlled atmosphere can be offered on drawer cylinder 22
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 211
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 can be also not provided with drawer cylinder 22, even if so, controlled atmosphere also has in space
With the presence of gases such as substantial amounts of nitrogen, user when body 23 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, the rear portion on the top of casing 20 defines and contains space 24, to accommodate pumping
Pump 41.In this embodiment, inventor has found that the rear portion Jing of existing refrigerating device top storage space is not often placed into
