Washing machine and control method

Abstract

A washing machine that brakes a spin-drying tub after a motor power supply for the spin-drying tub is interrupted, and a control method thereof. The washing machine includes a mode selection part for selecting a spin-drying mode, and a spin-drying timer for selecting a spin-drying time. The spin timer contains a spin switch and a motor control switch, each with a different operating time. When the drying mode is selected through the mode selection part, the drying switch of the drying timer is connected with the solenoid of the drainage motor, and the motor control switch is connected with the motor drive circuit through the start switch of the drainage motor. When the motor control switch is turned off (the drying switch is turned on) to interrupt the motor power supply before the selected drying time, the rotation speed of the drying tub is reduced. Thereafter, when the selected spin time has elapsed, the spin switch is turned off to interrupt power to the solenoid. Correspondingly, when braking with a small frictional braking force, since the friction between the brake band and the brake drum is reduced, the life-span of the braking device can be extended, and the braking force required when the spin-drying bucket is braked can be reduced. generated vibration and noise.

Description

technical field [0001] The present invention relates to a washing machine and a control method thereof, and more particularly to a washing machine and a control method thereof by cutting off the power supply of the drive motor before the drying time has elapsed. Background technique [0002] A typical double-tub type washing machine is separately provided with a washing tub and a drying tub in the washing machine housing, and an agitator is arranged on the bottom surface of the washing tub, and a drying motor is arranged on both sides of the lower part of the housing. and a washing motor are respectively used to drive the spin-drying bucket and the agitator. Meanwhile, a control panel is provided on one side of the top of the housing for selection of washing time and spin-drying time by the user. [0003] For this kind of double-tub washing machine, when the washing time is set by the washing timer after adding washing water, clothes, detergent, etc. into the washing tub, t...

Problems solved by technology

[0014] For this kind of traditional washing machine, when the spin-drying tub rotated by the motor at high speed is suddenly braked by the contact of the brake band and the brake drum after the drying time has elapsed, there is a problem that due to the acceleration of the brake band Friction shortens the life of the brake device and increases vibration and noise when braking the drum
