Washing machine

Abstract

A washing machine capable of reducing operational noise of a drainage pump. The washing machine includes a water tub installed in an outer case, a drainage pump adapted to drain wash water from the water tub, and a fixing device adapted to fix the drainage pump. The fixing device includes a support member extending from the drainage pump, vibration-proof members arranged to support an outer surface of the support member, and fixture members fixed to an inner surface of the outer case and adapted to support outer surfaces of the vibration-proof members.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of Korean Patent Application No. 2004-51658, filed on Jul. 2, 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 which can prevent vibrations of a drainage pump from being transmitted to an outer case. [0004] 2. Description of the Related Art [0005] In general, a washing machine includes a water tub for containing wash water, a rotating tub installed in the water tub having, and formed at a peripheral surface thereof with, a plurality of through-holes for use in a dry cycle, and a driving device for driving the rotating tub. In addition, the washing machine includes a water supply device supplying the wash water into the water tub, and a drainage device draining the wash water from ...

AI Technical Summary

Benefits of technology

[0010] The present invention has been made in view of the above mentioned problem. Accordingly, an aspect of the invention is to provide a washing machine which can reduce vibration transmitted from the drainage pump to the outer case of the washing machine, through the use of an improved installation structure for the drainage pump.

[0015] The first and second vibration-proof members may be formed with grooves, and at the outer surface of the support member are formed protruding ribs, in order to enhance a coupling force between the vibration-proof members and the support member.

Problems solved by technology

However, in the washing machine described above, since a support for the drainage pump is fixed directly to the bottom surface of the outer case by bolts or other fasteners, vibration, generated during operation of the drainage pump, is transmitted along the bottom surface of the outer case, resulting in operational noise.

Although the above described installation structure of the drainage pump may attenuate the vibration of the drainage pump to some extent through the use of the damper member, vibration of the bracket, used to support the drainage pump, is still transmitted to the frame of the washing machine through the fixing bolts, resulting in an unsatisfactory vibration attenuation effect.
