Abstract
The present invention relates to refrigeration technology field, more particularly to domestic refrigerator.A kind of intelligent keep-alive domestic refrigerator with oxygen-increasing device includes controller, oxygen concentration sensor, oxyty sensor, air-supply arrangement, heat exchanger, reversal valve; controller detects the numerical value of oxyty sensor; circular oxygenation or outer circulation oxygenation in being carried out when needing; keep dissolved oxygen in water concentration to be fluctuated in the section of a setting, extend the aquatic product keep-alive time.Interior circular oxygenation is the air in air-supply arrangement suction keep-alive room, and bubble is formed in water, increases dissolved oxygen in water concentration.The keep-alive interior space is limited, and by interior circular oxygenation, the oxygen concentration in air declines, gas concentration lwevel increase.Outer circulation oxygenation is to increase the air interchanger of keep-alive room, and the fresh air outside keep-alive room is changed to, exchanges heat simultaneously, bubble is formed in water, so as to increase oxygen content in the air in dissolved oxygen in water and keep-alive room.
Description
Technical field
The present invention relates to refrigeration technology field, more particularly to domestic refrigerator.
Background technology
Aquatic products mainly include fish, Shrimp waste, shellfish, algae, special aquatic products product and processing aquatic products.Mode of production master
Have fishing and cultivation, produced using ocean and inland waters, cultured fishes consumes in the form of fresh and alive, catch product with
The form consumption of frozen goods, algae are consumed in the form of processed goods.Fish nutrition is abundant, epidermis protective capability is poor, enzymatic activity is relatively strong,
Fish body surface, the gill and digestive system contain a large amount of spoilage organisms.Fish body starts little by little to soften, loses bullet again after stiff
Property, this is the result that contained various enzymes voluntarily decompose to fish body in fish body, and this change is referred to as autolysis.Although self-dissolving is made
Fish body is still within fresh state, but autolysis progress almost parallel with decay process, it is therefore necessary to avoids as far as possible
The generation of autolysis, fish body is maintained in the stiff phase as far as possible, the freshness of fish could be kept.Effect of the fish in microorganism
Under, it is low that protein, amino acid and other nitrogen substances in fish body are broken down into ammonia, trimethylamine, indoles, histamine, hydrogen sulfide etc.
Level product, makes fish body produce the stink with corrupt feature, and this process is referred to as corruption.The aquatic products of corruption may be poisoned, greatly
Majority can not accurately determine whether poisonous.
Keep-alive is a special category of preservation of fishery, is to maintain aquatic products freshness most effective way, be difficulty more
A kind of big technology.There is water keep-alive mainly to consider fish body situation, means of transportation, temperature, shipment density, oxygen supply, metabolism production
Thing, water quality, haulage time etc..Waterless keep-alive is mainly considered as cooling method, temporarily supports program, packaging material etc..Oxygen enhancement is more suitable
For freshwater fish.Anaesthesia uses chemical agent, only limits the use of in parent population, fry.Low temperature process is the ecology according to aquatic livestock
Ice temperature, the hibernation of fish half or hibernation are made using low temperature process, can reach the purpose of long range On Transportaion of Live.Without water law be using eel,
Crab, shellfish etc. bear the characteristics of water shortage ability is strong in short term, are transported using the anhydrous wet method of certain low temperature and humidity is kept.First, no
Life and death critical-temperature and freezing point with aquatic products is different, 7 DEG C or so of fish ecological ice-temperature, and the ice warm area of stalwart blood clam is -2.3 ~ 0
DEG C, Ruditapes philippinarum -1.7 ~ 1.5 DEG C, it could only use temperature control method live body is in dormancy or semidormancy in ice warm area
State；Secondly, slow gradient cooling, cooling are no more than 5 DEG C per hour；Finally, container should be closing temperature control formula, in holding container
Humidity, and consider the supply of oxygen.
Waterless keep-alive device and the refrigerator with the waterless keep-alive device（CN201510006481.1）It has studied anhydrous guarantor
Humid control and gas control living.A kind of refrigerator with keepalive feature（CN201510108371.6）Have studied humid control,
Temperature control, gas concentration lwevel, oxygen concentration and oxygenerator control.A kind of fresh-keeping refrigerator with keep-alive aquatile function
(CN201510128535.1) have studied purification keep-alive room air, improve keep-alive indoor oxygen content and with it is degerming, except different
The ion generator and ventilation equipment of function of odor.
Existing domestic refrigerator refrigerating chamber can be with keep-alive aquatic products, but do not have air interchanger, and the keep-alive time is shorter.Cause
This, there is provided a kind of intelligent keep-alive domestic refrigerator with air interchanger ensures the constant ecological ice-temperature in aquatic products of keep-alive room temperature
The oxygen consumption in section, turns into the industry technical issues that need to address.
The content of the invention
The technical problem to be solved in the invention is：The keep-alive interior space is limited, by interior circular oxygenation, in air
Oxygen concentration declines, gas concentration lwevel increase.Need to change in the air in the fresh air increase keep-alive room outside refrigerator
Oxygen content and dissolved oxygen in water, extend the aquatic product keep-alive time.
In order to solve the above technical problems, the technical solution adopted by the present invention is：Intelligent keep-alive family expenses with oxygen-increasing device
Refrigerator, including multiple refrigerating chambers of heat-insulated and independent temperature control, refrigerating chamber and keep-alive room, keep-alive room have air interchanger, are water
Product provides the oxygen that enough keep-alives need.
Air interchanger include swap out gas inlet pipe, heat-insulation layer, fin, heat exchanger, connection seam, filter mantle, insect-proof cover,
Valve, the gas exhaust pipe that swaps out, change gas access, change gas vent, after fresh air enters air interchanger, with that will arrange
After going out the air heat-exchange of refrigerator, through piping enter keep-alive room water in or cold-storage device.
Interior circular oxygenation is the air in air-supply arrangement suction keep-alive room, and bubble is formed in water, and increase dissolved oxygen in water is dense
Degree；Interior circular oxygenation does not have loss of refrigeration capacity, more saves, but the keep-alive interior space is limited, by interior circular oxygenation, in air
Oxygen concentration decline, gas concentration lwevel increase, may cause keep-alive aquatic products dead when serious, particularly high density keep-alive
Aquatic products.Outer circulation oxygenation is to increase the air interchanger of keep-alive room, and the fresh air outside keep-alive room is changed to, exchanged heat simultaneously,
Bubble is formed in water, so as to increase oxygen content in the air in dissolved oxygen in water and keep-alive room.
Air inlet is provided with filter, prevents foreign matter from entering, and blocks pipeline；Gas outlet is provided with insect-proof cover, and foreign matter enters pipe
Road may cause line clogging, and heat exchange efficiency declines.
In order to improve heat exchange efficiency, batch (-type) ventilation, the quick flowing of air, foul atmosphere and fresh air can be used
Heat-exchange time is shorter, and not enough fully, interval starts air-supply arrangement, is fully exchanged heat beneficial to foul atmosphere and fresh air.
