At the same time, because the pressure in the sealed machine is reduced, the external air passes through the vent pipe from the first port of the heat exchange chamber and then passes through the second The air inlet and the air inlet enter the motor chamber, and the air entering the motor chamber enters the drying chamber through the air holes on the bottom plate. At this time, the gas inside the machine forms a cycle; while the gas circulates, the air heater cools the air that has just entered the drying chamber. Heating, under the action of the deflector, the hot air is evenly distributed in the drying chamber, and then the clothes in the inner cylinder are dried; the hot air enters the heat exchange chamber of the heat exchanger through the buffer chamber and the draft elbow, Due to the aluminum heat-collecting fins on the ventilation pipe, the hot air will be absorbed part of the heat by the room-temperature gas that has just entered the ventilation pipe, because the third and fourth ports are staggered from each other to ensure that the hot air is fully in contact with the ventilation pipe before being discharged. ground contact. To sum up, the present invention uses a motor to realize the gas circulation in the whole cavity, and the gas will be recovered most of the heat by the air just entering before the gas is discharged, with high working efficiency and energy saving, which greatly reduces the drying cost of clothes .
