Summary:PROBLEM TO BE SOLVED: To prevent washings effectively from sticking or entangling each other. SOLUTION: A washing machine motor 17, which makes a drum rotate directly, is driven and controlled by an inverter main circuit 39 and a control circuit 44. The control circuit 44 works as a small angle rotating action controlling means. That is, one cycle is defined as making a washing machine motor 17 rotate by 30 degrees forward in a mechanical angle (the rotating speed is 50 rpm) and rotate by 30 degrees backward in a small period and five cycles are repeated in five seconds, so that a drum rotates forward and backward in five cycles.
