Benefits of technology

[0020] An object of the present invention is to provide a method for controlling a spinning stroke of a washing machine, in which the laundry amount is sensed more accurately in a spinning stroke.
[0021] Another object of the present invention is to provide a method for controlling a spinning stroke of a washing machine, in which rolling of a drum and vibration noise of a drum is minimized in a spinning stoke.

Problems solved by technology

That is, the more amount of the laundry there is, the loner time it takes for a drum to reach a preset speed.
However, in a related art spinning stroke it is difficult to sense the exact amount of the laundry in case that the laundry is tangled severely at the time when a spinning stroke is completed, although the related art spinning stroke is performed considering the laundry amount for enhancing an effect of laundry distribution.
Furthermore, since misjudgment of the laundry amount affects acceleration gradient, the laundry is not distributed uniformly and rolling of a drum and vibration noise of a drum may get worse during the spinning stroke.
Thereby, it causes customer complaints and deteriorates product reliability.

Abstract

A method for controlling a spinning stroke of a washing machine is disclosed. The method for controlling a spinning stroke of a washing machine comprises steps of: judging a first value of the laundry amount based on a frequency of water re-supply counted in a rinsing stroke; measuring the time taken for a drum rotating before a spinning stroke to reach a preset speed once a rinsing stroke is completed; judging a second value of the laundry amount based on the measured time; determining a final value of the laundry amount based on the first and second value of the laundry amount; and starting a spinning stroke based on the spinning condition determined based on the final value of the laundry amount. An object of the present invention is to provide a method for controlling a spinning stroke of a washing machine, in which the laundry amount is sensed more accurately in a spinning stroke.

Description

[0001] This application claims the benefit of the Patent Korean Application No. P2005-16877, filed on Feb. 28, 2005, which are hereby incorporated by reference as if fully set forth herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a washing machine, more particularly, to a method for controlling a spinning stroke of a washing machine based on an amount of laundry. [0004] 2. Discussion of the Related Art [0005] In general, a washing machine is an appliance used in a house most commonly, which washes clothes, cloth item, articles of clothing and beddings (hereinafter, the laundry) and removes dirt of the laundry by using impact of water, chemical action of detergent and friction force between water current and the laundry. [0006] A washing machine is classified into a pulsator type washing machine and a drum type washing machine. The pulsator type washing machine has a drum standing vertically, and the drum type washing machi...
