CONDENSING/DRYING DEVICE OF A DISHWASHER FOR IMPROVING A CONTACT AREA OF AIR AND IMPROVING CONDENSING AND COOLING EFFECTS, BY FORMING DEPRESSED AND PROMINENT SHAPES TO A PASSAGE THROUGH WHICH VAPOR OF HIGH TEMPERATURE PASSES

摘要

PURPOSE: A condensing/drying device of a dishwasher is provided to improve drying performance by mixing moisture with cold air and condensing and drying the moisture by an impeller and then making the dried cold air flow into a wash tube to lower the inner temperature. CONSTITUTION: A condensing/drying device of a dishwasher comprises a fan housing(205) having a vapor suction port(205a) communicating with the inside of a wash tub and an outside air suction port(205b) communicating with the outside; impellers(202,203) rotating by a motor inside the fan housing, to exhaust vapor of high temperature sucked through the vapor inlet and cold air sucked through the outside air suction port; a scroll(204) mixing air exhausted by the impellers; an inlet(213) making the mixed air and condensed water drops, exhausted along the scrolls by the impellers, flow into the wash tub; and an exhaust passage for exhausting quantity of mixed air corresponding to the quantity of the air sucked through the outside air suction port. The scroll has a passage for exhaust of the air the temperature of which is lowered and the moisture of which is condensed and dried. The scroll guides the air the temperature of which is lowered and the moisture of which is condensed and dried.
