Embodiment Construction

[0020] The following is attached Figures 1 to 3 Examples further describe the present invention in detail.

[0021] attached figure 1 It is a schematic structural diagram of a preferred embodiment. The box body 1 is provided with a storage area 11 and a refrigeration area 12. The fan 3 is a single-centrifugal double-outlet fan installed on the upper side of the evaporator 2. The return air channel 5 is located at the bottom of the evaporator 2. On the lower side, return air channel 5 is connected with the storage area and the refrigeration area of ​​the ventilated freezer. The fan 3 blows air to the air outlet channel 4, and the longitudinal air outlet 41 of the air channel 4 communicates with the storage area 11 of the air-cooled freezer, and the fan 3 takes away the gas that enters the refrigeration area from the return air channel 5. The airflow of the return air channel 5 will flow through the evaporator 2 and exchange heat to become cold air, then be drawn away by the ...

Abstract

The invention discloses an air cooling freezer. The air cooling freezer comprises a freezer body (1) which is provided with a refrigerating region (12) and a storage region (11). The air cooling freezer further comprises an air supply system. The air supply system comprises a draught fan (3), an air outlet pipeline (4) provided with an air outlet (41) and an air return pipeline (5) provided with an air return opening. The air outlet pipeline (4) is arranged on the inner side wall of the storage region (11). The air return opening of the air return pipeline (5) is formed in the inner side wall of the storage region (11). The draught fan (3) is arranged on the refrigerating region (12), the air return pipeline (5) penetrates the freezer body (1) to communicate with an exhaust inlet of the draught fan (3), and the air outlet pipeline (4) penetrates the freezer body (1) to communicate with an air blowing opening of the draught fan (3). Compared with the prior art, the air cooling freezer has the beneficial effects that a refrigerating circulation pipeline cannot be blocked, refrigeration is rapid and uniform, frosting does not occur, the process is simple and production is easy and has good social and economic benefits.

Description

technical field [0001] The invention relates to a freezer, in particular to an air-cooled freezer. Background technique [0002] At present, most of the freezer refrigeration on the market is an evaporative compression refrigeration method. The evaporator is installed around the inside of the freezer. The refrigeration system is composed of a compressor, a condenser, a throttling device, a dry filter and an evaporator. The refrigerant is in the refrigeration system. Under the action of the evaporator, the cycle of evaporation, compression, condensation, and throttling is continuously carried out, and the heat in the freezer is continuously transferred to the outside of the freezer, so as to achieve the purpose of refrigeration. The temperature is very low, the saturated humidity of the air is small, and the water vapor content per unit volume of air is very low. Under the effect of low temperature, the water vapor in the air condenses into frost on the outer wall of the evap...
