Problems solved by technology

If the drum 12 is rotated at the predetermined RPM (approximately 1000 RPM or more) in an unbalanced state in which the laundry W is nonuniformly distributed along the inner wall of the drum 12 as shown in FIG. 2, an eccentric force is applied to a rotary shaft of the drum 12 with the result that great vibration is generated.
Also, when the spin-drying process is performed in the unbalanced state, spin-drying time may increase and spin-drying errors may occur due to the unbalance.
Furthermore, when the laundry W is picked out after the completion of washing, a large amount of force

Embodiment Construction

[0036]Reference will now be made in detail to the embodiment of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiment is described below to explain the present invention by referring to the figures.

[0037]FIG. 3 is a sectional view illustrating the structure of a washing machine according to an embodiment of the present invention.

[0038]Referring to FIG. 3, the washing machine includes a water tub 11 mounted in a machine body 10 to receive water (wash water or rinse water) and a cylindrical drum 12 rotatably mounted in the water tub 11. The drum 12 has a plurality of spin-drying holes.

[0039]Outside a rear 11c of the water tub 11 is mounted a motor 15 to rotate a rotary shaft 13 connected to the drum 12 to perform washing, rinsing, and spin-drying operations. The motor 15 includes a stator 15a fixed to the rear 11c of the water tub 11, a rotor 15b rotatably mounted around ...

Abstract

Disclosed herein are a washing machine that performs a rinsing operation while rotating a drum at a predetermined RPM without stopping the drum after spin-drying and a rinsing control method thereof The washing machine includes a drum to receive laundry and a motor to rotate the drum. The rinsing control method includes rotating the drum to perform spin-drying and decelerating the drum to a predetermined velocity to perform rinsing. Consequently, it is possible to improve rinsing efficiency even using a small amount of water. Also, it is possible to uniformly distribute the laundry in the drum without eccentricity, although a laundry untangling process for spin-drying is performed only once during the rinsing, which is performed several times, thereby reducing the total rinsing time.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of Korean Patent Application No. 2008-0006797, filed on Jan. 22, 2008 in the Korean Intellectual Property Office, and of Korean Patent Application No. 2008-0006768, filed on Jan. 22, 2008 in the Korean Intellectual Property Office, the disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a washing machine and a rinsing control method thereof, and, more particularly to a washing machine that performs a rinsing operation while rotating a drum at a predetermined RPM and a rinsing control method thereof.[0004]2. Description of the Related Art[0005]Generally, a washing machine (normally, a drum type washing machine) is a machine, including a water tub to receive water (wash water or rinse water), a cylindrical drum rotatably mounted in the water tub to receive laundry, and a motor to generate a drive force ne...
