A sensor (not shown) for detecting the rotational angle position of the motor is provided to control the rotation of the motor 7 (see FIG. 1). With this configuration, the driving method 2 can be implemented without being bothered by the occurrence of slippage due to frictional transmission between the drive wheel 6 and the passive wheels 3a and 3b. The swing angle when performing this type of swing washing is not limited to 120 ° on the left and 120 ° on the right (a total of 240 °) as in the above-described embodiment.
A suitable angle less than 0 ° can be selected. The inner case 1 is reciprocally rotated or continuously rotated as described above, but the outer case 1 is fixed to the base 9 and does not rotate. In the prior art, gear drive or chain (sprocket) drive was used for rotational drive of the inner cylinder, but the present invention employs frictional drive of rollers to greatly simplify the mechanical structure. However, slippage accompanies friction transmission. In the first operation method, the occurrence of slippage does not cause any other trouble. In the second operation method, the above-mentioned sensor is provided to control the rotation of the motor, so that the problem of slippage can be eliminated.
