Embodiment Construction

[0018] During the washing process of the drum washing machine, the user first puts the laundry into the drum, and then selects the mode required by the user for washing. After the washing program is completed, it generally enters the draining program, dehydration program or drying program. Of course, it is also possible that the user directly puts the clothes washed by hand or other washing methods into the drum to perform the dehydration program. Therefore, according to the control method of the dehydration program of the drum washing machine of the present invention, when the user starts or the washing machine executes the initial stage of the dehydration program, the washing machine is first controlled to execute a drain program, as shown in FIG. 1 , in the drain program, the washing machine drives the drum to A preset lower speed is operated, for example, the rotation speed of the drum is lower than 200 rpm.

[0019] After the draining program runs for a certain period of ...

Abstract

The dewatering controlling program for drum-type washing machine includes one dewatering starting step, one washings loosening step, one dewatering step including increasing rotation speed and re-loosening, etc. The washings loosening step is always repeated after each step of increasing the dewatering rotation speed, so that the twisted washings are loosened effectively. The present invention can reduce vibration and noise caused by the twisted washings during dewatering greatly.

Description

technical field [0001] The invention relates to a control method for a dehydration program of a drum washing machine, in particular to a control method for reducing noise in the dehydration program of a drum washing machine. Background technique [0002] Generally, the drum washing machine realizes the washing of clothes through the combined action of the rotation of the drum driven by the motor and the lifter provided inside the drum. Since the drum is rotatably installed in the outer tub of the washing machine, and the outer tub is generally installed in the shell of the washing machine by means of suspension and support, the friction and impact of the clothes and washing water on the drum during the high-speed rotation of the drum is unavoidable. The ground will cause the drum to vibrate violently, resulting in noise. Through the research, it is found that the root cause of the loud noise of the drum washing machine is that during the process of spinning and drying the c...
