Washing machine having detergent supply device

Abstract

A washing machine having a detergent supply device for mixing detergent, filled in a detergent container, with wash water, and supplying the mixed detergent and wash water into a washing tub. The detergent supply device includes a housing, a detergent container, and water supply chambers. The housing includes a plurality of inlets connected with respective water supply pipes, and an outlet connected with a washing tub. The detergent container is detachably inserted in the housing and includes a plurality of detergent receiving chambers. The water supply chambers include a plurality of flow channels, and one of the flow channel is adapted to supply wash water, supplied from the inlets, into the detergent receiving chambers while adjusting the pressure of the wash water within a predetermined range.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of Korean Patent Application No. 2004-0044039, filed on Jun. 15, 2004 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a washing machine, and, more particularly, to a washing machine having a detergent supply device for mixing detergent, filled in a detergent container, with wash water, and supplying the mixed detergent and wash water into a washing tub. [0004] 2. Description of the Related Art [0005] In general, washing machines are apparatuses for washing laundry using frictional force caused by simultaneously agitating the laundry, detergent and wash water, contained in a washing tub, upon receiving driving power of a motor. The washing machines employ a detergent supply device to supply the detergent into a water tub in a mixed state with the ...

AI Technical Summary

Benefits of technology

[0011] Accordingly, it is an aspect of the present invention to provide a washing machine having a detergent supply device which can maintain the pressure of wash water, supplied into detergent receiving chambers, at a predetermined value, thereby preventing detergent from remaining in the detergent receiving chambers when low-pressure wash water is supplied, or from producing bubbles when high-pressure wash water is supplied.

Problems solved by technology

When the pressure of the wash water supplied into the detergent receiving chambers is low, the detergents may be supplied into the water tub in an insufficiently mixed state with the wash water, and thus may remain in the detergent supply device.

Further, when the pressure of the wash water is high, a great deal of bubbles as stated above may be produced, thereby invading other detergent receiving chambers filled with different kinds of detergents, or being leaked out of the washing machine.
