Abstract
The utility model relates to a refrigerator, in particular to a refrigerator which can adjust air components. Solving the problem of the prior art that the refrigerator is poor in preserving effect, the utility model contains a refrigerator box body. A refrigerating zone at the upper part of the refrigerator box body is provided with an air adjusting and freshness preserving box which is provided with an air exchange window made of silicon rubber film. Compared with the prior art, the utility model adds the air adjusting and freshness preserving box which can adjust the proportion of air concentration in the refrigeration chamber of the original refrigerator; and the air adjusting and freshness preserving box can initiatively adjust the proportion of the oxygen and the carbon dioxide to a suitable level in the process of preserving vegetables and fruits, then combine the temperature control in the refrigerator, so as to greatly extend the preservation time of fruits and vegetables.
Description
Technical field
The utility model relates to a kind of refrigerator, is specially a kind of refrigerator of adjustable gas composition.
Background technology
Existing refrigerator mainly is to utilize the temperature control that reduces storage to prolong the shelf-life of food.The amount of the disposable purchase food of people, fruit etc. is increasing now, though low temperature can prolong the quality guarantee period of food, variation has but taken place for mouthfeel, nutritional labeling after storage a period of time such as some fruit, and it is no longer delicious that taste becomes.How accurately the current refrigerator fresh-keeping function mainly still concentrates on controls on this thinking of temperature, as zero degree preservation technique, the little freeze techniques of-7 degree, many warm areas, alternating temperature district fresh-keeping refrigerator; And adopt accurate computer temperature control technology.The fridge freshness retaining technology also has new ideas such as " light wave increases aquatic foods ", " ecosystem is fresh-keeping ", " original fresh-keeping ", " it is fresh-keeping to tie up him ", " sterilization fresh-keeping ", new technology except temperature control.Utilize membrane technology to decompose the ethyl mercaptan of refrigerator inside and the gas that amine has peculiar smell; Ethene has the effect of the fruit that accelerates the ripening, so also must can decompose ethene; Utilize sterilizations such as preservative film, antiseptic, sodium rice palladium.For meat, milk etc. not the food of biologically active can play and well guarantee the quality preservation.But then need to consider the biologically active of fruits and vegetables for the preservation of fruit or vegetables comprehensively, could be effectively fresh-keeping.
Summary of the invention
The utility model is in order to solve the fruits and vegetables that exist in the prior art and to be stored in the problem of fresh-keeping effect difference in the refrigerator and the refrigerator that a kind of adjustable gas composition is provided.
The utility model is realized that by following technical scheme a kind of refrigerator of adjustable gas composition comprises refrigerator body, is provided with the regulating the qi flowing in the channels antistaling box in the chill space on refrigerator body top.The regulating the qi flowing in the channels antistaling box is provided with the gas exchange window that silicone rubber membrane is made.
In normal air, O
2And CO
2Concentration be respectively 21% and 0.03% all the other be mainly N
2Fresh fruit of vegetables after adopting is carrying out the metabolic metabolic activity of taking as the leading factor with aerobic respiration.So suitably reduce O
2/ CO
2Ratio, the aerobic respiration of fresh fruit of vegetables will be suppressed, and reduces its respiration rate, postpones the time that respiratory climacteric occurs, and has delayed metabolic speed, has reduced the consumption of nutritional labeling, thereby has postponed ripe aging.And hypoxemia helps delaying chlorophyllous decomposition, The addition of C O
2Can protect green.While O
2/ CO
2Ratio again can not be too low, otherwise anaerobic respiration can appear.Low concentration O
2Can make 1-amino-cyclopropane-1-carboxylic acid (ACC) can not be converted into ethene, relevant enzyme system also produces passivation or damaging action, reduces the sensitiveness of fruits and vegetables tissue to ethene.High concentration CO
2Environment can ethene suppressing produces and the physiological action of ethene, and suppresses acc oxidase and compete ethane cyclic amp receptor protein.So, low temperature, low concentration O
2, high concentration CO
2The adverse circumstance that all belongs to the fruits and vegetables normal activities.Fruits and vegetables produce O owing to self respiration consumes in storage
2, produce CO
2, make CO
2Concentration constantly increases, O in this process
2/ CO
2Ratio can reach the standard that helps fruits and vegetables storages.The gas exchange window that silicone rubber membrane is made then can reach this purpose, silicon rubber is a kind of organosilicon macromolecule polymer, by there being substituent siloxanyl monomers to be polymerized, with the continuous long-chain that forms soft easy song of silicon oxygen bond, be linked at together with the light current loosely between the long-chain, this structure has special gas permeability, N
2, O
2, CO
2Saturating property ratio is 1: 2: 12, CO in casing
2Can discharge by silicone rubber membrane in the time of too much, and extraneous N
2, O
2Then can enter in the casing, keep O in the storage environment by silicone rubber membrane
2, CO
2Ratio is suitable.
Compared with prior art, the utility model has been set up the regulating the qi flowing in the channels antistaling box with adjustments of gas concentration ratio function in the refrigerating chamber of original refrigerator.This case can active adjustment make its interior O
2, CO
2The level that ratio keep to be fit in the process of storage fruits and vegetables combines with temperature control in the refrigerator again, has greatly delayed the time of preserving fruit and vegetable utilizing.
