To couple the decoration panel 14 to the console 13 and at the same time fix the decoration panel 14, it is preferable that the upper fixing hole 16, the lower fixing hole 17, and the coupling hole 19 are formed on the first groove 15 and the second groove 18.
In addition, to protect the console 13 and the control panel 8 and improve the appearance, it is preferable that the decoration panel 14 is made of metal material.
Also, it is preferable that the lower fixing protrusion 25 and the inner fixing protrusion 27 are made thin or made of a material having ductility such that the lower fixing protrusion 25 and the inner fixing protrusion 27 are inserted into the corresponding lower fixing hole 17 and the corresponding coupling hole 19 and then bent by a predetermined angle.
It is preferable that one end of each of the lower fixing protrusion 25 and the inner fixing protrusion 27 should be protruded perforating the holes 17 and 19. Accordingly, it is preferable that each of the lower fixing protrusion 25 and the upper fixing protrusion 27 has a length greater than a depth of each of the corresponding holes 17 and 19.
Also, it is preferable that an end corner of each of the upper fixing protrusion 23, the lower fixing protrusion 25, and the inner fixing protrusion 27 is rounded to be easily inserted into the corresponding hole.
The procedure for coupling the decoration panel 14 to the console 13 will now be described with reference to FIGS. 2 and 3.
First, the second bent portion 22 is inserted into the first groove 15. At this time, the upper fixing protrusion 23 is inserted into the upper fixing hole 16. Thereafter, the decoration panel 14 is rotated by a predetermined angle centering on the upper fixing protrusion 23 inserted into the upper fixing hole 16, and is then loaded into the front surface of the console 13.
Herein, the first extending portion 24 is inserted into the first groove 15 and the second extending portion 26 is inserted into the second groove 16. The lower fixing protrusion 25 is inserted into the lower fixing hole 17 and the inner fixing protrusion 27 is inserted into the coupling hole 19.
By doing so, the decoration panel 14 is loaded into the front surface of the console 13. After that, an end of each of the lower fixing protrusion 25 and the inner fixing protrusion 27 protruded backward is bent by a predetermined angle. By doing so, the decoration panel 14 is stably fixed to the console 13 by the lower fixing protrusion 25 and inner fixing protrusion 27.
For more effective fixing of the decoration panel 14, it is possible to insert the upper fixing protrusion 23 into the console 13 to be protruded backward from the console 13 and bent the protruded end portion of the upper fixing protrusion 23 by a predetermined angle, thereby fixing the decoration panel 14. At this time, it is preferable that the upper fixing protrusion 23 is made of a material having ductility such that the upper fixing protrusion 23 is inserted into the upper fixing hole 16 and is then bent.
Also, it is preferable that the length of the upper fixing protrusion 23 is greater than the depth of the corresponding upper fixing hole 16 such that one end of the upper fixing protrusion 23 perforates the upper fixing hole 16 and is protruded toward a backward direction of the console 13.
Meanwhile, the console 13 into which the decoration panel 14 is assembled is coupled to an upper rear portion of the washing machine.
As described above, according to the washing machine of the present invention, since the decoration panel is coupled to the console without a separate fixing member such as a screw, the number of parts is reduced, thereby saving the manufacturing cost.
Also, since the protrusions formed in the decoration panel are inserted into the corresponding holes and then bent and fixed, it is possible to fix the decoration panel to the console easily. By doing so, the assembling time of the decoration panel and the console can be shortened.
In addition, since the portions fixing the decoration panel are not exposed to an outside, the appearance of the washing machine can be improved.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
