The all-in-one washing and drying machine with water condensation method is mainly composed of a bucket assembly, a heating pipe and a closed loop of a condensation pipe. Since there is condensed water flowing from top to bottom on the inner wall of the condensing pipe, the hot and humid gas transported by the bucket assembly can be cooled and the moisture in the hot and humid gas can be condensed. The hot and humid gas turns into dry and cold gas and enters the heating tube. After being heated by the heater, it becomes dry and hot gas. The dry and hot gas then flows into the barrel assembly, absorbing the moisture in the barrel and turning into hot and humid gas. Repeat the cycle to achieve the effect of drying.

In the traditional water condensation method, the water flow enters the upper part of the condenser pipe from the water inlet valve along the water inlet pipe, and then the water flow flows down the inner wall of the condenser pipe. At the same time, hot and humid air flows from bottom to top, and in the inner cavity of the condensation pipe, the hot and humid air exchanges heat with cold water and condenses to form water. However, in this solution, the hot and humid air and cold water are in a common condenser tube cavity, and the cold water will flow down quickly, resulting in low heat transfer efficiency; at the same time, the hot and humid air is in direct contact with the cold water, and it is easy to be sucked into the heating tube together with the cold water, which affects drying Effect.
