Specific embodiment
This utility model is described in detail below with reference to embodiment shown in the drawings.But the embodiment is not
Limit this utility model, structure that one of ordinary skill in the art is made according to the embodiment, method or functionally
Conversion is all contained in protection domain of the present utility model.
Fig. 1 to Fig. 3 is referred to for one better embodiment of this utility model.This utility model provides a kind of anxious jelly constant temperature
Room 10, including formed the inner bag 11 of a storage chamber, the shell 12 on the outside of the inner bag 11, and be arranged at inner bag 11 with it is outer
Between shell 12 and the cool storage material 13 that is attached on the inner bag 11.
Cooling air duct is formed between the inner bag 11 and shell 12 and between cool storage material 13 and shell 12, it is described outer
The air inlet 14 and air outlet 15 connected with the cooling air duct is offered on shell 12.Wherein, the air inlet 14 is opened in outer
The rear side of shell 12, and the air inlet 14 is diagonally positioned with air outlet 15.The inner bag 11 towards the air inlet 14 one
Side offers quickly cooling air inlet 16 and is also equipped with air door 17 at the quickly cooling air inlet 16.
The quickly cooling air inlet 16 is opened on rear side of inner bag 11 and corresponding with the position of the air inlet 14, the inner bag
11 front side is further opened with quickly cooling air outlet 18.When the air door 17 is opened, the cold of anxious jelly thermostatic chamber 10 is flowed into from air inlet 14
Air directly enters storage chamber by quickly cooling air inlet 16, and with the food directly contact wherein stored so that inner bag 11
In the food that stores quickly cool down.
To cause the rapid conduction of cold is realized between storage chamber and cooling air duct and cool storage material 13, reduce and tie up
The temperature of the storing intracavity is held, the inner bag 11 is obtained by the higher material of metal or other heat conductivitys.In the present embodiment,
The inner bag 11 adopts aluminium alloy or rustless steel to be obtained.The shell is obtained by polystyrene or ABS resin, its heat conductivility compared with
Difference, effectively slows down the anxious cold frozen in thermostatic chamber 10 and passs and reduce the impact that outer bound pair suddenly freezes temperature in thermostatic chamber 10.
When cold air enters anxious jelly thermostatic chamber 10 from the air inlet 14, the accumulation cold of the cool storage material 13.At this
In embodiment, the inner bag 11 and shell 12 are in rectangular structure, the rear side of the inner bag 11, bottom, top and both sides
Being sticked has the cool storage material 13, so that cool storage material 13 can accumulate sufficient cold, and the cool storage material 13
The all directions of storage chamber can be freezed simultaneously, uniformity is improved, the local temperature difference of storing intracavity is eliminated.
This utility model also provides a kind of wind cooling refrigerator for being equipped with above-mentioned anxious jelly thermostatic chamber 10, and the wind cooling refrigerator has
Casing 20, the refrigeration compartment being formed in casing 20, the cooling air channel 23 on rear side of the refrigeration compartment and refrigeration system.
The refrigeration system is included being arranged in the cooling air channel and the vaporizer 21, wind of cold is provided for the refrigeration compartment
Machine 22 and it is connected to the press of the vaporizer 21（It is not shown）.Specifically, the refrigeration compartment be freezing compartment, the urgency
Freeze thermostatic chamber 10 in freezing compartment, the cooling air channel 23 is formed with the air outlet 24 for connecing relative with the air inlet 14.
The freezing compartment is additionally provided with positioned at the anxious return air inlet 25 frozen below thermostatic chamber 10.
During compressor operation, blower fan 22 is opened for the cold on 21 surface of vaporizer to be sent to freezing compartment and anxious jelly thermostatic chamber
10, temperature is reduced, and the heat of cool storage material 13 is also taken away by air-flow simultaneously, and the calorific potential of cool storage material 13 is reduced.Also, master control
Always according to anxious, unit freezes whether thermostatic chamber 10 needs quickly cooling to lower the temperature, to control the open and close of air door 17.When the vaporizer
When 21 stoppings are freezed or carry out defrost, blower fan 22 cuts out, and the temperature in freezing compartment is raised, and now the anxious thermostatic chamber 10 that freezes then leads to
Cross 13 released cold quantity of cool storage material and relatively stable state is maintained with the temperature for keeping storing intracavity, reduce temperature recovery and ripple
It is dynamic.
In the wind cooling refrigerator running, when the anxious jelly thermostatic chamber 10 needs to carry out quickly cooling cooling, control is opened
The air door 17 so that the cold air in cooling air channel 23 is directly entered inner bag via quickly cooling air inlet 16；Quickly cooling cooling terminates
When, air door 17 is closed, the cold air in cooling air channel 23 flows through the anxious cooling air duct for freezing thermostatic chamber 10, remains anxious and freezes thermostatic chamber 10
Interior temperature.
Specifically, main control unit detect it is anxious freeze after thermostatic chamber 10 is opened, when being re-closing off, judge described anxious to freeze constant temperature
Room 10 needs to carry out quickly cooling cooling.It is, of course, also possible to corresponding temperature sensor is set in the storing intracavity, and then according to interior
Temperature inversion inside gallbladder 11 is judging whether to need to carry out quickly cooling cooling.After opening air door 17, main control unit is also dropped to quickly cooling
The time of temperature is added up, and when the time of quickly cooling cooling preset duration t is reached, is terminated quickly cooling and lowered the temperature and close air door 17.
Likewise it is possible to according to real-time temperature change in storage chamber with judge whether terminate quickly cooling cooling process.
During food preservation, the anxious temperature comparisons' schematic diagram for freezing thermostatic chamber 10 and freezing compartment is illustrated in figure 3, its
In, A is the temperature fluctuation curve of the freezing compartment；B is the anxious temperature fluctuation curve for freezing thermostatic chamber.As can be seen that general
As shown in curve A, the temperature fluctuation of stable operation stage is about ± 1K for logical freezing compartment, and the defrost stage, and its temperature can go up
Rise 5K；And this utility model suddenly freezes thermostatic chamber 10 and is about ± 0.2K, the temperature in defrost stage in the temperature fluctuation of stable operation stage
Degree rises.
In sum, this utility model suddenly freezes thermostatic chamber 10 by quickly cooling air inlet 16 so that cold air directly freezes permanent with anxious
Foodstuff surface in greenhouse 10 contacts so that food cells generate band quickly through ice crystal, reduces cell damage；And by storing
Air-flow indirect refrigeration in cold material 13 and cooling air duct, maintains the anxious temperature frozen in thermostatic chamber 10, effectively reduces temperature recovery
With fluctuation, the loss of food nourishment composition is reduced, keep the mouthfeel and freshness of food.
It should be understood that, although this specification is been described by according to embodiment, but not each embodiment only includes one
Individual independent technical scheme, this narrating mode of description is only that those skilled in the art will should say for clarity
Bright book as an entirety, the technical scheme in each embodiment can also Jing it is appropriately combined, forming those skilled in the art can
With the other embodiment for understanding.
Those listed above is a series of to describe the tool for being only for feasibility embodiment of the present utility model in detail
Body illustrates that they are simultaneously not used to limit protection domain of the present utility model, all to be made without departing from this utility model skill spirit
Equivalent implementations or change are should be included within protection domain of the present utility model.
