Description

Technical Field

[0001] The present invention relates to the technical field of clothes dryers, and in particular to a direct-exhaust clothes dryer with a rear heat source component. Background Art

[0002] A clothes dryer is a device for drying clothes. When the clothes dryers currently on the market are in use, heated dry hot air can enter the drum of the clothes dryer. The dry hot air entering the drum can dry the clothes in the process of the clothes being rolled by the drum. After the dry hot air dries the clothes and becomes wet and cold air, it can be discharged from the drum. Through the above process, the clothes can be dried. However, in the existing clothes dryer structure, the dry hot air entering the drum cannot flow through the drum to the maximum extent, resulting in poor drying effect and low drying efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a direct-exhaust clothes dryer with a rear heat source component, which has the advantages of good drying effect and high drying efficiency for clothes located in a drum.
