[0060] In order to address the problems of insufficient contact between condensed water and drying airflow and short heat exchange time when condensed water flows through the condensation area 13, this embodiment proposes that a plurality of guide ribs 123 are provided on the inner side surface of the outer cylinder rear wall 12, and the plurality of guide ribs 123 are arranged at intervals on the inner side surface of the outer cylinder rear wall 12; the condensed water entering the inner side surface of the outer cylinder rear wall 12 flows from top to bottom along the guide ribs 123, so that the drying airflow is in full contact with the condensed water, thereby improving the condensation efficiency.

[0061] In order to solve the problem that condensed water cannot enter the condensation duct section 21 and the condensation area 13 in time, resulting in poor condensation efficiency, the present embodiment proposes that the outer cylinder rear wall 12 is formed with m mounting openings, and the m mounting openings are arranged in a one-to-one correspondence with the m condensation duct sections 21; a condensation water pipe 3 is provided at each mounting opening, and the condensation water pipe 3 includes a water inlet section 31, an outgoing water section 32 and an inner water outlet section 33 which are arranged in sequence and connected; the water inlet section 31 is formed with a condensation water inlet 311, and the outgoing water section 32 is formed with an outgoing water hole 321, and the outgoing water hole 321 connects the outgoing water section 32 and the condensation duct section 21; the inner water outlet section 33 is located in the condensation area 13 and the inner water outlet section 33 is formed with an inner water outlet hole 331, the inner water outlet hole 331 is inclined downward and the inner water outlet hole 331 connects the inner water outlet section 33 and the condensation area 13;
