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, and 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
The color and luster of thing, mouthfeel, freshness etc. keep constant as far as possible.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 food every time and is required for carrying out evacuation action, and troublesome poeration cannot
Consumer is liked.
It is fresh-keeping using vacuum storing compartment, due to casing etc. be rigid structure, vacuum state to be kept, to pumped vacuum systems
Requirement it is very high, the sealing property of refrigerator is required very high, often picks and places 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 refrigerator doors etc. every time needs the very big strength of expense, causes user using 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：As 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 solving but failing all the time always
The technical barrier for successfully solving.
