Description
- This application is a continuation of U.S. application Ser. No. 14/638,293, filed on Mar. 4, 2015, which claims the benefit of Korean Patent Application No. 10-2014-0027442, filed on Mar. 7, 2014 in the Korean Intellectual Property Office, the disclosures of which are incorporated herein by reference.
- Embodiments of the present disclosure relate to a clothes dryer, more particularly a clothes dryer provided with a filter unit and a filter cover having a coupling structure corresponding to each other.
- A clothes dryer is an appliance to dry wetted-laundry after washed by using hot and dry air.
- In general, a clothes dryer may be classified into a gas type and an electricity type depending on power sources, and may be classified into exhaust type dryers and condensing type dryers depending on the method of processing moisture collected from laundry.
- The exhaust type dryer is configured to discharge humid air discharged from a drum to the outside through an air discharge duct which is extended long.
- In the condensing dryer, humid air discharged from the drum is condensed to remove the moisture therefrom using a heat exchanger, and the dried air is conducted back into the drum again so as to be re-circulated. Since the flow of air is formed in a shape of a closed loop, it is difficult to use gas as a heat source and thus electricity is mainly used as a heat source.
