Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a washing machine.
2. Description of the Related Art
Generally, washing machines include a drum in which laundries such as garments, linens, and fabrics (hereinafter, referred to collectively as fabrics) are washed by water and detergent (hereinafter, referred to as wash water) fed into a tub in washing mode. Then, the garments are rinsed and excess water is extracted from the garments in rinsing and spinning modes.
During use or transportation of the washing machine, a cabinet cover of the washing machine can be scratched or deformed, causing degradation in appearance. Further, users may be surfeited with the frontal appearance of the washing machine after long use of the washing machine. In addition, since the cabinet cover is coated with a coating material, the manufacturing process of the cabinet is complicated and manufacturing costs increases.
To eliminate such disadvantages, the cabinet cover can be constructed including: a non-coated rear cabinet cover having a fabric opening in a center portion; and an exchangeable, injection-molded plastic front cabinet cover which has a fabric opening larger than the fabric opening of the rear cabinet cover and covers a front side of the rear cabinet cover. In this case, the frontal cosmetic appearance of the washing machine can be improved by exchanging the front cabinet cover. However, water can reach the rear cabinet cover through the fabric opening and corrode the rear cabinet cover. Further, although the rear cabinet cover can be formed to have the same color as the front cabinet cover for cosmetic purposes or the exposed portion of the rear cabinet cover by the fabric opening can be coated with a coating material, these modifications will entail complicated manufacturing processes and increased material costs.

SUMMARY OF THE INVENTION

Accordingly, the present invention is directed to a washing machine that substantially obviates one or more problems due to limitations and disadvantages of the related art.
An object of the present invention is to provide a washing machine that has a sealing structure for preventing water form reaching a rear cabinet cover through a fabric opening.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, there is provided a washing machine including: a rear cabinet cover including a rear fabric opening through which fabrics pass; a front cabinet cover disposed at a front side of the rear cabinet cover and including a front fabric opening corresponding to the rear fabric opening; and a gasket including a screening portion for covering a periphery of the rear fabric opening.
In another aspect of the present invention, there is provided a washing machine including: a tub including a tub fabric opening through which fabrics pass; a rear cabinet cover disposed at a front side of the tub and including a rear fabric opening through which fabrics pass; a front cabinet cover disposed at a front side of the rear cabinet cover and including a front fabric opening corresponding to the rear fabric opening; and a gasket including a tub coupling portion coupled to the tub, a cover coupling portion coupled to at least one of the front cabinet cover and the rear cabinet cover, a connection portion connecting the tub coupling portion and the cover coupling portion, and a screening portion formed on the cover coupling portion to cover a periphery of the rear fabric opening for sealing up the rear cabinet cover.
In a further another aspect of the present invention, there is provided a washing machine including: a cabinet cover including a fabric opening through which fabrics pass; and a gasket sealing an inside of the cabinet cover and covering a periphery of the fabric opening.
According to the washing machine of the present invention, the gasket includes the screening portion covering the fabric opening, such that the fabric opening of the rear cabinet is not exposed to the outside. Thus, water cannot flow into the rear cabinet cover through the fabric opening, thereby preventing corrosion of the rear cabinet cover. Further, the rear cabinet cover is not required to have the same color as the front cabinet cover or be coated with a coating material. Therefore, the rear cabinet cover can be manufactured through a simple process with less cost.
