The drying methods of the drying and washing integrated machine mainly include two types: direct discharge and condensation. The working principle of the direct exhaust type is that after the air is heated by a heater, the clothes are heated and turned into damp and hot air, which is discharged out of the room, forming a cycle and continuously expelling the moisture from the clothes, achieving the goal of drying the clothes. The working principle of condensation type is that after the air is heated by a heater, it enters the cylinder to heat clothes. The cylinder becomes moist and hot air, and then through the condensation system, the moisture is solidified into water and collected in the water storage box, forming a cycle, continuously draining the moisture from the clothes, achieving the goal of drying clothes.

A household dryer can efficiently dry wet clothes, bed sheets, towels, and other household textiles in a short period of time, reducing the waiting time for clear weather and the labor of manual drying, allowing users to obtain dry and soft clothing in a short period of time.
