Washing machine and rinsing control method of the same

Abstract

Disclosed herein are a washing machine and a rinsing control method of the same that is capable of increasing spin-drying RPM before the final rinsing, such that the spin-drying RPM before the final rinsing is higher by a specific percentage than a predetermined RPM, to strongly squeeze out residual detergent, contained in laundry, from the laundry, and adding soaked rinsing time, during the final rinsing, to completely dissolve residual detergent contained in laundry, thereby improving the rinsing efficiency. The washing machine includes a rotary drum to receive laundry and a motor to rotate the rotary drum. The rinsing control method includes determining whether a current operation is a rinsing operation, and, when the current operation is the rinsing operation, controlling intermediate spin-drying RPM and rinsing time to remove residual detergent from the laundry.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority benefit of Korean Patent Application No. 2007-0022212, filed on Mar. 6, 2007 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND[0002]1. Field[0003]Embodiments relate to a washing machine and a rinsing control method of the same, and, more particularly, to a washing machine and a rinsing control method of the same that is capable of controlling spin-drying revolutions per minute (RPM) during rinsing and rinsing time, thereby improving the rinsing efficiency.[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) and a cylindrical rotary drum rotatably mounted in the water tub to receive laundry, that washes the laundry by lifting and dropping the laundry in the rotary drum along the inner surface of the ...

AI Technical Summary

Benefits of technology

[0010]In an aspect of embodiments, there is provided a washing machine and a rinsing control method of the same that is capable of controlling spin-drying RPM during rinsing and rinsing time, thereby improving the rinsing efficiency.

[0011]In another aspect of embodiments, there is provided a washing machine and a rinsing control method of the same that is capable of increasing spin-drying RPM before the final rinsing, such that the spin-drying RPM before the final rinsing is higher by a specific percentage than a predetermined RPM, to separate residual detergent, contained in laundry, from the laundry, thereby accomplishing effective rinsing.

[0012]In a further aspect of embodiments, there is provided a washing machine and a rinsing control method of the same that is capable of adding soaked rinsing time, during the final rinsing, to completely dissolve residual detergent contained in laundry, thereby further improving the rinsing efficiency.

Problems solved by technology

While the washing machine performs washing, however, the detergent, supplied into the rotary drum, may be settled on the bottom of the rotary drum, with the result that the detergent is not sufficiently dissolved or mixed with the water.
