PROBLEM TO BE SOLVED: To provide a pump device for a dish washer by which a pump configuration is simplified, and a washing chamber occupancy space is increased inside the machine main body of the dish washer. SOLUTION: A pump P includes a brushless motor, which generates a rotary driving force in one direction, and includes: a shaft S, a magnet rotor; a stator; and an impeller 28. A switching valve V is connected to the pump P. Washing water is introduced to the switching valve V by rotating the impeller 28 of the brushless motor. In this case, the pump P is used for both the cases of supplying washing water to a washing chamber 13, and discharging the washing water to the outer part of the machine body 12, so that a space for the one pump is eliminated. Thus, the proportion of the occupancy of the space in the washing chamber 13 to an internal space NS is increased. COPYRIGHT: (C)2004,JPO |
