Embodiment Construction

[0017] Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings.

[0018] The heating system of one embodiment may be applied to a dryer and a washing machine having a drying function. Dryers (including washing machines with drying function) can be divided into condensation dryers and exhaust dryers. Condensation dryers dry clothes by circulating heated air in a closed loop. Therefore, the condensation dryer also includes a condensation unit that removes moisture by condensing humid air. A vented dryer does not require a condensing unit because it is designed to exhaust the humid, heated air to the outside. A dryer having a heating system in one embodiment will be described below.

[0019] FIG. 1 is a cross-sectional view of a dryer with a heating system according to one embodiment.

[0020] Referring to FIG. 1 , the dryer includes a cabinet 11 defining an appearance therein. The front co...
