Condensation assembly of clothes treatment device and washing and drying machine

The invention provides a clothes processing device condensation assembly and a washing and drying machine. The condensation assembly of the clothes processing device comprises an outer barrel and a heat exchange assembly, wherein the heat exchange assembly is arranged on the inner wall of the outer barrel; and the heat exchange assembly exchanges heat with the humid and hot air in the outer cylinder in a non-contact manner, so that liquid drops in the humid and hot air can be condensed out. A non-direct-contact condensation mode is adopted, the heat exchange assembly is arranged on the inner wall of the outer barrel, a condensing agent stably flows in the heat exchange assembly and is prevented from being in direct contact with humid and hot air in the outer barrel, the situation that the condensing agent splashes due to the high air speed in the barrel and consequently clothes are wetted can be prevented, and the phenomenon that the condensing agent is reversely sucked into a heating air channel is eliminate
