DETAILED DESCRIPTION

[0019] like Figure 1-4 As shown, the dryer provided by the present invention includes a body 1 having a first passage 20 extending through both ends for the entry of clothes and other items to be dried. A cover plate 2 is provided above the first passage 20. A second passage 30 extending through both ends for the entry of hangers is provided in the middle of the cover plate 2. Both ends of the second passage 30 are open. Each end of the first passage 20 is provided with an openable and closable sliding door 15. The sliding door 15 is connected to a controller 3, and its opening and closing are controlled by the controller 3. The controller 3 is mounted on the body 1. An anti-pinch door sensor 14, connected to the controller 3, is provided on one side of the sliding door to detect the presence of clothes near the sliding door, preventing them from being trapped and damaged when the door is closed.

[0020] A heating device and an air circulation device are provided within the housing on at least one side of the first channel 20. In this embodiment, the heating device is a heat exchanger 4, and the air circulation device is a fan 5. The housing below the first channel 20 is a hollow structure. The inlet of the fan 5 communicates with the first channel through this hollow structure. The outlet of the fan 5 is connected to the heat exchanger 4 via a dryer 6 and an air duct 7. The air at the fan outlet is dried by the dryer 6 and then enters the heat exchanger. The outlet of the heat exchanger leads to the first channel. The air heated by the heat exchanger 4 is blown into the first channel, drying the clothes in the first channel. The air in the first channel is then drawn into the fan through the hollow structure at the bottom, forming a cycle. Two heat exchangers are provided in this embodiment.

[0021] Heat exchanger 4 uses steam for heat exchange. A steam generator 8 is installed within the machine body 1. The water inlet of steam generator 8 is connected to a water inlet pipe 9, through which a certain amount of water is injected into steam generator 8. Steam generator 8 is connected to the inlet of the coil in heat exchanger 4 via a steam pipe 10. An electrically controlled valve 11 is installed on steam pipe 10 to control the steam supply. This electrically controlled valve is connected to a controller. The outlet of the coil in heat exchanger 4 is connected to steam generator 4 via a return pipe 12. Return pipe 12 is equipped with a steam trap (not shown). This means that after the steam in the heat exchanger coil exchanges heat with air passing through the heat exchanger, the air temperature increases. After this heat exchange, the steam cools down, producing condensate. This condensate returns to the steam generator through the return pipe. The steam trap on the return pipe only allows water to pass, not gas.

[0022] A temperature sensor 13 is installed in the first channel for detecting the temperature in the first channel. The temperature sensor 13 is connected to the controller 3. When the temperature in the first channel rises to a first set value, the controller controls the electric control valve 11 to close, and the steam generator 8 stops supplying steam to the heat exchanger; when the temperature in the channel drops to a second set value, the controller controls the electric control valve 11 to open and start supplying steam.

[0023] The utility model operates as follows: a hanging conveyor system delivers at least one garment into the first channel of the dryer. The number of garments delivered must not exceed the maximum capacity of the first channel. A controller then controls the sliding doors at both ends of the dryer to close the dryer. If garments are located near the sliding doors, the dryer alarm sounds, requiring manual intervention. After the set drying time has expired, the sliding doors open, and the hanging conveyor system removes the garments from the first channel.
