PURPOSE: To cool the wet air by city water, to condense and eliminate the moisture contained therein, to eliminate the need of a heat exchanger and a cooling fan, to miniaturize the dryer, to improve the installability, and also, to realize the high condensation efficiency by introducing water from the peripheral direction of an eddy chamber, and providing an injector for injecting it from an injection port in the center, while turning it, in a condensing part.

CONSTITUTION: Wet air containing moisture is sucked out by a circulating fan 52 from a drum 6 and fed to a condensing part 35. On the other hand, a feed water solenoid valve 44 is opened, and city water fed to an injector 41 from a water pouring hose 46 flows into an eddy chamber 36 in the peripheral direction from a introducing hole 55 in the injector 41, and turns violently in the chamber. Therefore, injection water from an injection hole 41a is also injected, while turning, receives force in the radial direction by centrifugal force, and flows out along an enlarged part 56. Accordingly, water is injected like an inverted cone, and the wet air in the condensing part 35 is condensed and dehumidified. In this case, a contact area to an air current is enlarged, and simultaneously, since a path passing through the inside of the condensing part 35 by turning of infection water becomes long, the condensation efficiency is improved.
