Abstract

PURPOSE: To accurately detect the occurrence of one-way rotation and secure the safety of operation by detecting the change rate of the right and left revolving speeds when a motor is excited during the washing operation, and detecting the one-way rotation based on the difference between the right and left revolving speeds via the change rate. CONSTITUTION: A control device 16 excites a motor 7 for the stirring operation in the washing process, and right-turn excitation, stop, and left-turn excitation are repeatedly applied to the motor 7. The left-turn excitation is applied to the motor 7 after the right-turn excitation, and vice versa. A revolving speed of the motor 7 is detected by the output from a revolving speed detector 8. When the revolving speed is not 10rpm or above, the difference from the previous revolving speed is detected. When the revolving speed is not 5rpm or above, the overload warning of the motor 7 is dislayed, and the stirring operation is stopped. When the difference is 5rpm or above, one-way rotation is warned and displayed, and the stirring operation is stopped.

2. Description of the Related Art As is well known, the operating process of a fully automatic washing machine is such that a washing process, a rinsing process (for example, twice), and a dehydration process automatically proceed. The washing process is performed by supplying water and stirring. The rinsing process is composed of drainage, temporary waiting for draining after drainage, low speed dewatering, high speed dewatering, natural stop, water supply, rinsing by stirring, and the final rinsing step. The dehydration process consists of drainage, temporary waiting for draining after drainage, low-speed dehydration, high-speed dehydration, and natural stop, and finally an end alarm sounds.

In the washing process, the rotor is rotated left and right by the left and right rotation of the motor, and the stirring operation is performed. By the way, in a washing machine that uses a planetary gear as the speed reduction mechanism, the reaction force of the rotation of the planetary gear causes the outer ring gear to rotate in a direction opposite to the revolution direction of the planetary gear during the washing operation. When the brake is released and the state is free, the rotational force in the opposite direction is transmitted to the washing / dehydrating tub to rotate the washing / dehydrating tub in the direction opposite to the rotary vanes to enhance the washing effect.

Sixthly, when the energization time to the motor is made different in the left and right directions, the left and right rotation angles are controlled after the motor rotation speed change rate exceeds the extreme value, so that the right rotation is rotated to the left rotation or the left rotation. The rotation is controlled by the changed rotation angle from the time of the rotation speed 0 at which the rotation shifts to the right rotation, and the set angle is surely executed.
