Description
Technical field
The utility model relates to a kind of refrigerator, is specially a kind of fresh-keeping refrigerator of adjustments of gas composition automatically.
Background technology
Existing refrigerator mainly is to utilize the temperature control that reduces storage to prolong the shelf-life of food.The disposable purchase food of people now, the amount of fruit etc. is increasing, though low temperature can prolong the quality guarantee period of food, variation has but taken place in mouthfeel, nutritional labeling after storage a period of time such as some fruit, 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 for solve the refrigerator that exists in the prior art preserve the fruits and vegetables process since gas componant and change in concentration cause freshness fast the problem of decline a kind of fresh-keeping refrigerator of adjustments of gas composition automatically is provided.
The utility model is realized that by following technical scheme a kind of fresh-keeping refrigerator of adjustments of gas composition automatically comprises refrigerator body, is provided with the ca cold storage chamber in the chill space of refrigerator body, the indoor CO that is provided with of ca cold storage
2Concentration sensor, O
2Concentration sensor, the ca cold storage chamber is communicated with appendix, and the appendix end is serially connected with gas mixing ratio device, N successively
2Gas generator, wherein CO
2Concentration sensor, O
2Concentration sensor is connected with the integrated chip input respectively, N
2The output of gas generator and integrated chip is connected, and also is provided with unidirectional exhaust pressure valve on the ca cold storage chamber.
In the process that stores fruits and vegetables, to produce CO owing to the physiological change of fruits and vegetables self
2, consume O
2So, CO
2Concentration sensor, O
2Concentration sensor is monitored CO respectively
2Concentration and O
2CO is worked as in the variation of concentration level
2The signal that concentration sensor provides is higher than after the value of setting integrated chip start signal output N immediately
2Gas generator, N
2Gas generator produces N
2, and then carry out a certain proportion of proportioning by gas mixing ratio device and air, be sent to the indoor CO of making of ca cold storage by appendix then
2Concentration reduces.
Equally, work as O
2The indoor O of concentration sensor monitoring ca cold storage
2After the signal that provides in the concentration process was lower than setting value, integrated chip is start signal output N immediately
2Gas generator, N
2Gas generator produces N
2, and then carry out a certain proportion of proportioning by gas mixing ratio device and air, be sent to the indoor O of making of ca cold storage by appendix then
2Concentration raises.So make CO all the time
2Concentration and O
2Concentration is maintained within a certain range.
Principle: 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.
Compared with prior art, the utility model has increased the ca cold storage chamber again on the basis of current refrigerator, and gives the indoor O that installed of ca cold storage
2And CO
2The concentration monitor element detects O in storing the fruits and vegetables process
2And CO
2Change in concentration is then by integrated chip control N
2Gas generator work, N
2Gas generator makes O in the process of carrying gas
2And CO
2Concentration remains on respectively and is fit in the preserving fruit and vegetable utilizing extent and scope.The fresh-keeping degree that can keep fruits and vegetables again in conjunction with the original refrigeration system of refrigerator the long period.
