Abstract
A drum washing machine and a clothes dryer equipped with a thermoelectric module are disclosed. The thermoelectric module includes a heat absorption side and a heat dissipation side which absorbs and dissipates heat at a junction between two dissimilar metals depending on direction of current flow through the junction. The heat absorption side is disposed at a hot air flowing passage. Accordingly, the drying apparatus can increase energy efficiency with minor structural modification and becomes environmentally friendly unlike a conventional drying apparatus using a heat pump.
