Patent ID: 8231737

Claim:
A dish washer/dryer comprising: a washing tub for accommodating an object to be washed; a washing section for washing the object to be washed; a heater for heating washing water; an exhaust port for discharging moisture inside the washing tub; an air blower for blowing outside-air; a mixing section disposed at an upstream side of the exhaust port, the mixing section mixing outside-air and washing-tub-inside-air with each other; and an air volume distribution section for changing a feeding ratio of the outside-air into the washing tub and the mixing section, wherein an outside-air path for introducing the outside-air into the mixing section and a washing-tub-inside-air path for communicating with the mixing section are disposed at a downstream side of the air volume distribution section, wherein the air volume distribution section has dampers in the washing-tub-inside-air path and the outside-air path, a washing tub damper provided in the washing-tub-inside-air path and an outside-air damper provided in the outside-air path are connected to be integrated with each other, wherein the dampers are connected in a freely rotatable manner to the air volume distribution section such that the opening degree of the washing tub damper is continuously increased according to an increase of a blowing air volume from the blower, and wherein the freely rotatable dampers are individually weighted so that the washing tub damper is biased toward the washing-tub-inside-air path such that upon deactivating the air blower the washing tub damper moves to close the washing-tub-inside-air path.
