Patent ID: 7921681

Claim:
A washing-drying/drying machine comprising: a tub mounted in a cabinet; a drum rotatably disposed in the tub for receiving laundry; a cooling water supply unit for supplying cooling water to condense moisture in air discharged from the drum; and a condensing plate mounted between the drum and an inner wall of the tub for receiving the cooling water to condense the moisture in the air, the condensing plate having a first and second surfaces, wherein the first and second surfaces face opposite directions, wherein a first flow passage formed by the condensing plate between the first surface and the drum is configured to be larger than a second flow passage formed by the condensing plate between the second surface and the inner wall of the tub, wherein the air discharged from the drum flows across the first surface of the condensing plate through the first flow passage, and the cooling water flows across the second surface of the condensing plate through the second flow passage, wherein cooling water flowing across the second surface of the condensing plate to cool the condensing plate causes condensation of moisture in the air discharged from the drum as the air flows across the first surface of the condensing plate, and wherein the condensing plate has a main body, the main body is spaced apart from the inner wall of the tub by a gap, and the gap between the inner wall of the tub and the main body is less than a predetermined value such that the cooling water is collected between the condensing plate and the inner wall of the tub due to surface tension, and the collected cooling water falls down when new cooling water is introduced into a space between the condensing plate and the inner wall of the tub.
