The passage of the lower section of evaporator 15 not other temperature-changing chambers of approach are led to by second return air inlet 52, so without set guarantor to it
Warm thermal insulation layer.
The quantity of blower fan 6 is two, and rotating speed is adjustable, and two blower fans 6 are separately positioned on the first wind inlet channel and second and enter
At the first air inlet 21 and the second air inlet 22 in wind air channel, and two blower fans 6 are preferably all centrifugal blower 6, i.e. blower fan 6 for axle
To air intake, the structure of radial direction air-out, thus can go out by air inlet through hollow shaft by the cold air suction of the top of evaporator 15, by radial direction
Wind and the cold air of suction is drained into the first wind inlet channel and the second wind inlet channel, using the blower fan 6 of the structure type, not only
Can realize for cold wind being incorporated into the first wind inlet channel and the second wind inlet channel, and occupancy ducting assembly that can also be as few as possible
14 thickness space, and then ducting assembly 14 can be made to as far as possible thin, the storage space of occupancy temperature-changing chamber that will not be excessive.
During work, with reference to shown in Fig. 1 and Fig. 2, the pressure difference produced by two blower fans 6 makes the first temperature-changing chamber 12 and second
Temperature-changing chamber 13 forms airflow circulating with evaporator 15 respectively, i.e. the air-flow difference in the first temperature-changing chamber 12 and the second temperature-changing chamber 13
The lower section of evaporator 15 is flowed into by the first return airway and the second return airway, air-flow from bottom to top passes through evaporator 15,
Flow through cooled during evaporator 15；At the same time, the cooled gas in the top of evaporator 15 is entered by the first wind inlet channel and second
Wind air channel is separately flowed into the first temperature-changing chamber 12 and the second temperature-changing chamber 13, thus respectively to the first temperature-changing chamber 12 and the second temperature-changing chamber
13 are freezed.
Wherein, because the first temperature-changing chamber 12 and the cold wind of the second temperature-changing chamber 13 introduce cold wind, institute separately through a blower fan 6
Can be separately controlled with the air quantity for entering into the first temperature-changing chamber 12 and the second temperature-changing chamber 13, for example, can be divided by a controller
The rotating speed of the first blower fan 6 and the second blower fan 6 is not controlled, to realize controlling respectively the temperature of the first temperature-changing chamber 12 and the second temperature-changing chamber 13
Degree；Blower fan 6 of the air quantity for entering into the first temperature-changing chamber 12 and the second temperature-changing chamber 13 completely by being each correspondingly arranged is additionally, since to determine
It is fixed, so the regulation to the first temperature-changing chamber 12 and the temperature of the second temperature-changing chamber 13 is independent of each other, i.e. the intake of the first temperature-changing chamber 12
Can't be reduced because of the increase of the intake of the second temperature-changing chamber 13, and then, the excursion of the intake of each temperature-changing chamber is more
Greatly, i.e. the temperature change of each temperature-changing chamber is interval wider, can better meet the demand of user；Further, since the first air intake
Air channel and the second wind inlet channel are divulged information with maximum gauge all the time, and windage is smaller, so also more energy-conservation.
In addition, the quantity of evaporator 15 can be multiple, multiple evaporators 15 are spaced from each other, each evaporator 15 and one
Or multiple temperature-changing chambers are correspondingly arranged, you can so that the airflow circulating of a part of temperature-changing chamber flows through an evaporator 15, and make another
The airflow circulating of part temperature-changing chamber flows through another evaporator 15, can so prevent the gas cross in two parts evaporator 15
Circulation, the classification for being more beneficial for food materials is preserved.
Including multiple temperature-changing chambers, each described temperature-changing chamber is equipped with the wind inlet channel of the side for leading to evaporator 15 and leads to
The return airway of the opposite side of evaporator 15, the wind inlet channel of each temperature-changing chamber and/or the inside of return airway are equipped with
Blower fan 6, the rotating speed of the blower fan 6 is adjustable.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model know-why is not departed from, some improvement and replacement can also be made, these change
Enter and replace also to should be regarded as protection domain of the present utility model.
