Claims

[Claims for Utility Model Registration] 1. A washing tub, a rotary blade rotatably disposed on the inner bottom of the washing tub, and a motor for driving the rotary blade, and the motor is automatically reversed. In this washing machine, the operating speed of the rotary blades is set in a range of 1100 rpm to 350 rpm, and the operating speed of the rotary blades is set in a range of 1100 rpm to 350 rpm, and The driving time is set to a maximum of 3 seconds during normal rotation and reverse rotation, and at least a pause time necessary for the motor to reverse is provided between normal rotation and reverse rotation of the rotary blade. washing machine. 2. The washing machine according to claim 1, wherein the operating time of the rotary blade is set to be the same during forward rotation and reverse rotation. 3. The washing machine according to claim 1, wherein the down time is set shorter than the operating time. 4. The washing machine according to claim 1, wherein the rotary blade is provided at the center of the inner bottom of the washing tub. 5. The washing machine according to claim 1, wherein the inner wall of the washing tub is formed into an approximately wavy uneven surface by alternately forming valleys and peaks. 6. The washing machine according to claim 1, wherein the washing tub is a washing/drying tub and is provided in an outer tub.
