<p>PURPOSE: A dryer is provided to remove foreign material on a filter by rotating the filter and extending a flow path guide to a radial direction. CONSTITUTION: A dryer comprises: a coolant flow path; a circulation flow path; a heat exchanger which is formed in the cross point of the circulation flow path and the coolant flow path; a cooling fan which generates a first air flow of the coolant flow path; a circulation fan which generates a second air flow of the circulation flow path; one or more motors(23) which rotate the cooling fan and the circulation fan; a filter(24) which filters a foreign material from air; a flow path guide which generates a third air flow and separates the foreign material stuck to the filter; an acoustic unit(41) which induces sound pressure to a direction which is different to the second air flow in order to generate a third air flow.</p> |
