In addition, the air inlet duct 21 and the return duct 22 may be injection molded.
Example 2
Unlike embodiment 1, the dehumidifying module 3 includes a plurality of baffles arranged along the first air inlet or the first air outlet at intervals; the plurality of baffles form an angle alpha with the flowing direction of the air, wherein the angle alpha is more than 0 degree and less than 90 degrees; a water receiving tank is arranged below the baffles; a second flow channel is formed between the adjacent baffles;
when the refrigerator is in the defrosting mode, when the damp and hot air flows through the second flow channel, the water vapor therein is contacted with the baffle plate to collide and coalesce into water drops, and then the water drops into the water receiving tank along the baffle plate, so that the damp and hot air is converted into dry and hot air, and then the evaporator 131 is subjected to defrosting treatment, and the defrosting effect is improved.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the disclosure is not limited to the precise construction, arrangements, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
