Hereafter, a laundry machine in accordance with one embodiment of the present invention will be described in detail. FIG. 1 is a schematic view showing a laundry machine in accordance with one embodiment of the present invention, and FIG. 2 is a diagram showing that a side cover of FIG. 1 is coupled to a side panel by a hook.
Referring to FIG. 1, the laundry machine in accordance with the present invention includes a front cover 20 forming a front surface of a cabinet, a top cover 30 forming an upper surface thereof and a side cover 90.
The front cover 20 and the side cover 90 have an excellent appearance considering a design. They are respectively formed of stainless steel so as not to be corroded in spite of frequent contact with water. In order to enhance a processability of the covers, a kind of the stainless steel in STS 300 group having a low spring back characteristic is used to form the covers resulting from checking physical properties of several kinds of the stainless steel.
The front cover 20 is integrally formed resulting from molding a stainless steel plate. The front cover 20 is provided with a central portion provided with an inlet 21 at which a door 40 is mounted, an upper portion provided with an opening 22 at which a control panel 50 and a detergent box 60 are installed, and a lower portion provided with a pump service hole 23 at which a pump cover 70 is installed. Through this pump service hole 23, a user can put his/her own hand into the laundry machine so as to maintain a pump (not shown) installed in the laundry machine.
Referring to FIG. 2, the side cover 90 is coupled to an exterior of a side panel 80 formed of steel. That is, the entire side surface of the laundry machine is not implemented as the side cover 90 of the stainless steel, but implemented as a double structure of the side panel 80 mounted therein and the side cover 90 of the stainless steel that is attached to the exterior of the side panel 80.
Accordingly, the appearance of the laundry machine becomes excellent by using the side cover 90 of the stainless steel for its exterior. And, using the side panel 80 of steel for its interior, not the stainless steel, it is capable of reducing a material cost for the stainless steel.
Further, the side surface of the laundry machine is formed with the double structure of the side panel 80 and the side cover 90 having proper vibrations different from each other, accordingly it is capable of absorbing and attenuating noise and vibration generated while the laundry machine is operated.
Hereafter, various methods for coupling the side cover to the side panel will be described. FIG. 3 is a partially cut view of A portion in FIG. 2, FIG. 4 is a diagram showing that a side cover of FIG. 1 is adhered to a side panel, and FIG. 5 is a section view taken along line V-V in FIG. 4.

As another coupling method, referring to FIGS. 6 and 7, the side cover 90 is coupled to the side panel 80 by screws 97, not the double-sided tape 95 (refer to FIG. 5). To this end, the side cover 90 is provided with a plurality of protrusions 92. The protrusions 92 are formed as a separate member and attached to the side cover 90 using the double-sided tape or the adhesive agent. The protrusions 92 are respectively provided with screw grooves 92 a to which the screws 97 are respectively coupled.
The side panel 80 is provided with a plurality of insertion grooves 83 for inserting the protrusions 92 thereinto in correspondence to the protrusions 92. The insertion grooves 83 are respectively provided with through holes 83 a through which the screws 97 pass.
With such configuration, the screws 97 are respectively coupled to the screw grooves 92 a of the protrusions 92 at an inner side of the side panel 80 through the through holes 83 a. Accordingly, the screws 97 are not outwardly exposed.
Else, when the side cover 90 is coupled to the side panel 80, it may be possible to use the hook, the double-sided tape, the adhesive agent, the screw, etc., alternately and simultaneously.
As aforementioned, in the laundry machine in accordance with one embodiment of the present invention, the entire side surface of the laundry machine is not implemented as the cover formed of the stainless steel, but implemented as the double structure in which the side panel and the side cover of the stainless steel that is attached onto the side panel are coupled to each other. Accordingly, by the side cover of the stainless steel for the exterior, the laundry machine can have the excellent appearance. And, by using the side panel that is not formed of the stainless steel for the interior, it is capable of reducing the material cost. Further, the side surface of the laundry machine is implemented as the double structure of the side panel and the side cover having proper vibrations different from each other, accordingly it is capable of absorbing and attenuating noise and vibration generated while the laundry machine is operated.
