Claims

[Claims for Utility Model Registration] 1. A washing machine equipped with a dehydration tank for dehydrating objects to be dehydrated and an electric motor for rotating the dehydration tank, including a rotation speed detector for detecting the rotation speed of the dehydration tank; , a rotation control device that rotates the dehydration tank at a lower speed than normal rotation based on the output signal from the rotation speed detector to prevent the dehydration material from being squeezed too much, and the rotation control device rotates the dehydration tank at a lower speed than normal rotation to prevent the dehydration tank from squeezing too much. a deceleration means that controls energization to the electric motor to reduce the rotation speed of the dehydration tank when the rotation speed reaches a first set rotation speed lower than the rotation speed;
A washing machine comprising an acceleration means for increasing the rotation speed of the dehydration tub by controlling energization of the electric motor when the rotation speed reaches a second set rotation speed lower than the first set rotation speed. 2. In a washing machine equipped with a dehydration tank for dehydrating objects to be dehydrated and an electric motor for rotationally driving the dehydration tank, a timer device that counts the rotation time of the dehydration tank, and a washing machine that measures the rotation time of the dehydration tank based on an output signal from the timer device. and a rotation control device that repeatedly controls starting and stopping of the electric motor to rotate the dehydration tank at a lower speed than normal rotation to prevent the material to be dehydrated from being squeezed too much. an actuating means for turning on power to the electric motor for a first set time shorter than the time at which the electric motor is reached; and a halting means for turning off electric power to the electric motor for a second set time after the actuating means has energized the electric motor. A washing machine characterized by:
