FIG. 5 is a cross-sectional view taken along line 5-5 of FIG. 1.

Referring to FIG. 5, the lower end of the front surface of the front case 16 extends forward to be rounded at a predetermined curvature ‘r’. Also, the lower end of the front surface of the front case 16, i.e., an end of the extension part 163a extends to be spaced a predetermined distance ‘d’ from the rear end of the door seating part 121 to the front side of the top cover 12. Thus, introduction of water flowing along the left and right edges of the front surface part of the front case 16 into the panel case 15 may be minimized.

FIG. 6 is a front perspective view of the panel decor according to an embodiment of the present invention, and FIG. 7 is a rear perspective view of the panel decor.

Referring to FIGS. 6 and 7, the panel decor 18 according to an embodiment of the present invention may be mounted on the lower end of the front surface of the front case 16 to prevent a coupling member for coupling the front case 16 to the top cover 12 from being exposed to the outside.

In detail, the panel decor 18 may include a decor body 181, a coupling hook 182 protruding backward from an upper end of a rear surface of the decor body 181, a movement prevention rib 185 extending downward from a rear surface of the decor body 181, a pair of coupling bosses protruding backward from left and right edges of the rear surface of the decor body 181, and a pair of pressing protrusions 184 protruding backward from a lower side of the coupling bosses 183. Also, the panel decor 18 may have substantially the same width and length as the door seating part 121.

In more detail, the decor body 181 may include a rounded part 181a extending downward to extend forward while being smoothly rounded and a bent part 181b bent downward from an end of the rounded part 181a.

Also, the coupling hook 181 may be provided in plurality. The plurality of coupling hooks 181 may be disposed to be spaced apart from each other in a longitudinal direction of the decor body 181.

Also, the pressing protrusion 184 may be configured so that a user pushes the rear case 17 backward by using his hands after separating the rear case 17 when it is intended to separate the panel decor 18 from the panel decor coupling part 161b. That is, when the user pushes the pressing protrusion 184 forward after separating the coupling member coupled to the coupling bosses 183, the panel decor 181 may rotate to be separated from the panel decor coupling part 161b.

Also, the movement prevention rib 185 may be provided in plurality on the rear surface of the panel decor 18. The plurality of movement prevention ribs 185 may be disposed to be spaced apart from each other in the width of the panel decor 18. Also, when the panel decor 18 is seated on the panel decor coupling part 161b of the front case 16, the movement prevention rib 185 is fitted into the movement prevention groove 167. Thus, since the panel decor 18 does not move in a left and right direction in the state of being seated on the panel decor coupling part 161b, the coupling member may be easily coupled to the coupling boss 183.

Also, an end of the coupling boss 183 may be closely attached to the coupling protrusion 166, and thus, the coupling groove defined in the coupling boss 183 and the coupling hole defined in the coupling protrusion 166 may be aligned with each other. Also, the coupling member such as a screw may be inserted into the coupling boss 183 by passing through the coupling protrusion 166.

Also, the pressing protrusion 184 protrudes backward from the front case 16 through the interference prevention hole 165 to allow the user's finger to push the front case 16 backward. In detail, when the panel decor 18 is coupled to the panel decor coupling part 161b, the pressing protrusion 184 rotates in the state of being inserted into the interference prevention hole 165 to protrude backward from the front case 16

Also, the coupling hook 182 is inserted into the hook hole 162a.

FIG. 8 is a front perspective view of the rear case constituting the panel case according to an embodiment of the present invention, and FIG. 9 is a rear perspective view of the rear case.

Referring to FIGS. 8 and 9, the rear case 17 according to an embodiment of the present invention is coupled to the rear surface of the front case 16.

In detail, a front edge of the rear case 17 is closely attached to a rear edge of the front case 16, and a plurality of coupling holes 171 are defined in an inner edge of the rear case 17. The plurality of coupling holes 171 may be defined at points corresponding to the positions of the plurality of rear case coupling bosses 168 protruding from the rear surface of the front case 16. Thus, in the state in which the rear case 17 is closely attached to the rear surface of the front case 16, the coupling member such as the screw may be inserted into the rear case coupling bosses 168 by passing through the coupling holes 171.

Also, a plurality of fixing ribs 172 may protrude from the left and right edges of the front surface part of the rear case 17. The plurality of fixing ribs 172 may be inserted into rear case fixing holes 169a of the rear surface of the front case 16. In the state in which the plurality of fixing ribs 172 are inserted into the rear case fixing holes 169a, movement of the rear case may be prevented. In this state, the coupling member may be inserted into the coupling hole 171.

Also, a plurality of heat dissipation holes 173 may be defined in the rear case 17. Each of the plurality of heat dissipation holes 173 may formed in such a manner that a portion of the rear case 17 is cut or bent. In detail, a portion of the rear case 17 may be cut in a U shape, and the cut portion may be bent to form a guide rib 173a having a louver shape together with the heat dissipation hole 173. Thus, air within the panel case 15 may be discharged to the outside through the heat dissipation holes 173 and then be guided to the bottom surface, on which the washing machine is installed, by the guide rib 173a.

The coupling ribs 174 may be disposed on the left and right edges of the lower end of the rear surface of the rear case 17, respectively. Here, one or more coupling holes 174a may be defined in each of the coupling ribs 174.

FIG. 10 is a longitudinal cross-sectional view taken along line 10-10 of FIG. 1, FIG. 11 is a longitudinal cross-sectional view taken along line 11-11 of FIG. 1, and FIG. 12 is a longitudinal cross-sectional view taken along line 12-12 of FIG. 1.

Referring to FIGS. 10 to 12, the panel decor 18 covers the coupling structure of the lower end of the front case 16 and the top cover 12.

In detail, as illustrated in FIG. 10, the front case 16 may descend from an upper side of the top cover 12 so that the fitting protrusion 169 extending from the bottom surface of the front end of the front case 16 is inserted into the coupling slit 123 of the top cover 12.

Also, as illustrated in FIG. 11, the coupling member such as the screw is inserted into the coupling hole 164 defined in the bottom of the front end of the front case 12 and the coupling hole 124 defined in the top surface of the top cover 12. Thus, the front case 16 may be stably fixed to the panel case seating part 122 of the top cover 12.

Also, as illustrated in FIG. 11, the panel decor 18 is mounted on the panel decor seating part 161b. In detail, as illustrated as a dotted line of FIG. 11, in the state in which the coupling hook 182 of the panel decor 18 is inserted into the hook hole 162a defined in the front case 16, the panel decor 18 rotates in a direction (a first direction) in which the panel decor 18 is closely attached to the front surface of the front case 16. Thus, the pressing protrusion 184 of the panel decor 18 may rotate in the state of being inserted into the interference prevention hole 165 of the front case 16 to become a horizontal state. As described above, the coupling boss 183 is closely attached to the coupling protrusion 166.

In this state, when the coupling member passes through the coupling protrusion 166 and is inserted into the coupling boss 183, the panel decor 18 may be stably coupled to the front case 16. Thereafter, to separate the panel decor 18, the coupling member inserted into the coupling boss 183 is separated, and then, when the pressing protrusion 184 is pushed forward, the panel decor 1 rotates in a second direction that is opposite to the first direction. Also, when the panel decor 18 is held and pulled forward, the coupling hook 182 is separated from the hook hole 168.

As illustrated as an arrow in FIG. 10, since the bent part 181b defined the lower end of the panel decor 18 is closely attached to the rear end of the door seating part 121, the water flowing down along the surface of the panel decor may not be introduced into the panel case 15 but be introduced into the washing drum through the door seating part 121. Thus, it may be possible to minimize the possibility that the electrical components accommodated in the panel case 15 due to moisture and moisture cause electric problems.

After the coupling of the panel cover 18 is completed, the rear case 17 is fixed and coupled to the front case 16.
