Then, an air pump can be connected to the air duct 12 so that airflow enters the heating plate 13 through the air duct 12. When the housing 1 is started, the heating plate 13 is equipped with an air pump. A heating wire (not shown in the figure) heats the airflow. The hot airflow is ejected from the holes on the surface of the heating plate 13 and dries the clothes on the rack. The dried exhaust gas is discharged through the air inlet 15 and enters the heat exchange box 14. At this time, the exhaust gas is at a high temperature. The high-temperature exhaust gas will diffuse and flow in the heat exchange box 14. Because the first baffles 17 are staggered, the exhaust gas will make a slight S-shaped movement under the guidance of the first baffles 17, increasing the residence time of the exhaust gas in the heat exchange box 14. During the process, the high-temperature exhaust gas will...
