PROBLEM TO BE SOLVED: To ensure an efficient rinsing operation by the effective use of characteristic of a drive motor. SOLUTION: A commercial use ac voltage is rectified and stepped up by a dc voltage generation circuit, and then it is supplied to a three-phase inverter circuit which drives a compact brushless motor 51. Accordingly, the output characteristic of the compact brushless motor is utilized effectively to thereby implement an efficient rinsing operation. |
