Method for controlling washing during spinning in tilt-type washing machine for attenuation of vibration

Abstract

Method for controlling washing during spinning in a tilt-type washing machine for attenuation of vibration, including (a) a main rotation step for exerting a centrifugal force to the laundry gathered to a center of the inner tub for spreading the laundry to an inside wall of the inner tub before the water discharging step, (b) a laundry disentangle alternately rotating step for alternately rotating the inner tub for a preset times to disentangle the laundry spread to the inside wall of the inner tub, and (c) a supplementary rotating step for rotating the inner tub at a preset RPM to keep the laundry in the tilted inner tub spread evenly during the water discharge step, or alternatively (a) a laundry disentangle alternately rotating step for alternately rotating the inner tub to eliminate the eccentricity of the laundry in the inner tub before the water discharge step, and (b) a determining step either for carrying out a control pattern to eliminate the eccentricity of the laundry if the eccentricity of the laundry after the step (a) is greater than a preset value, or for proceeding to the water discharging step if the eccentricity of the laundry after the step (a) is smaller than the preset value, whereby attenuating the vibration to the minimum.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a Reissue of U.S. Pat. No. 6,401,284, which was granted on Jun. 11, 2002, based upon U.S. application Ser. No. 09 / 709,549, filed Nov. 13, 2000.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a tilt-type washing machine, and more particularly, to a method for controlling washing during spinning in a tilt-type washing machine for attenuation of vibration.[0004]2. Background of the Related Art[0005]In general, the necessity for the tilt-type washing machine, having the vertical type washing machine and the drum type washing machine applied thereto, is in increasing trend day by day because the tilt-type washing machine has an excellent washing performance and convenience of use. Referring to FIG. 1, a related art tilt-type washing machine is provided with a body 1, an outer tub 2 mounted tilted in the body, an inner tub 3 rotatably mounted in the outer tub, a driving device...

AI Technical Summary

Benefits of technology

The present invention provides a method for controlling washing during spinning in a tilt-type washing machine for attenuation of vibration. The method includes a series of steps with a water supplying step, an alternating rotating step, a water discharging step, a spinning step, and a rinsing cycle. The method also includes a laundry disentangle step and a determining step to eliminate eccentricity of the laundry before the water discharging step. The technical effects of the invention include minimizing vibration, reducing eccentricity of the laundry, and improving the efficiency of the washing process.

Problems solved by technology

First, the washing step or the rinsing step before the water discharging step has the following problems, when, in one side the washing or rinsing is made as the washing water penetrates the laundry by the centrifugal force generated at rotation of the driving motor, and in the other side the washing or rinsing is made as the washing water and the laundry make friction to each other as the washing water circulation is inversed following regular / reverse direction rotation of the driving motor.

Consequently, the water discharging step and the spinning step carried out in a state the laundry is entangled leads the entangled laundry stuck to the inside wall of the inner tub in the spinning step, without being distributed evenly on the inside wall of the inner tub, which causes eccentricity of a weight that is a cause of a vibration.
