Detergent dissolving device and washing machine having the same

Abstract

Disclosed are a detergent dissolving device for a washing machine capable of improving solubility of detergent, and a washing machine having the same. The detergent dissolving device includes a powdered detergent box, and the powdered detergent box includes a detergent receiving portion, and a water feed portion defined at a periphery of the detergent receiving portion to feed water into the detergent receiving portion so as to cause rotating motion of water received in the detergent receiving portion. The detergent dissolving device further includes a cover provided to open or close the detergent receiving portion. The cover includes a water discharge portion to discharge the water out of the detergent receiving portion.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Korean Patent Application No. 2008-0072394, filed on Jul. 24, 2008 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND[0002]1.

AI Technical Summary

Benefits of technology

[0010]Therefore, it is an aspect of the present invention to provide a detergent dissolving device for a washing machine capable of improving solubility of detergent, and a washing machine having the same.

Problems solved by technology

A problem of the above-described conventional detergent feeder is that powdered detergent received in the detergent receiving portion is often fed into the water tub in an incompletely dissolved state.

The incompletely dissolved powdered detergent may settle at the bottom of the water tub, causing detergent residue.

In addition, as the powdered detergent is fed to laundry, it may be stuck on the laundry and remain on the laundry even after completion of a laundry washing operation.

Another problem is that some of the powdered detergent, input into the detergent receiving portion of the detergent box, remains in the detergent box even after completion of a laundry washing operation.

In particular, when a water source feeds water at a low water pressure, the water may insufficiently remove the powdered detergent from the detergent receiving portion, increasing the amount of detergent residue.

The detergent residue may be introduced into the water tub along with water during a rinsing operation after the laundry washing operation, deteriorating rinsing performance, or may be hardened in the detergent box, causing contamination of the interior of the detergent box.
