SUMMARY OF THE INVENTION An object of the present invention is to provide a clothes dryer that can solve the above-mentioned problems of the prior art with simple means without providing a separate heat exchanger outside the dryer main body.

[Means to solve the problem]

The above purpose is to dry clothes by circulating warm air through the path of clothes storage room → circulation fan → heater → clothes storage room. The cross-sectional shape of the circulation duct is formed into a wave shape, and outside air is blown onto the outer surface of the circulation duct to cool it, and the outside air is exhausted to the outside of the aircraft through a space between the outer frame that constitutes the exterior of the aircraft and the circulation duct. The moisture condensed in the circulation duct due to the above cooling is discharged to the outside of the aircraft body through a drainage duct provided in the circulation duct.

[Effect]

Utilizing the circulation duct, which is absolutely necessary to configure the hot air circulation path, heat exchange is performed between the circulating air containing moisture inside the duct and the cooling air blown onto the outside surface of the duct, causing condensation of the circulating air. and drain the water out of the aircraft through the drainage duct. This configuration eliminates the need for a separate heat exchanger.
A dehumidifying clothes dryer can be realized.
