Referring to FIG. 1, a washing machine 1 includes a cabinet defining an appearance, a top plate 10 seating on a top portion of the cabinet 20, a tub 7 received in the cabinet 20, a front panel 40 coupled to a front portion of the cabinet 20, a control panel 30 coupled to an upper portion of the front panel 40, a door 401 coupled pivotally to a central portion of the front panel 40, and a decoration panel coupled to edges of the front panel 40 and the control panel 30.
The decoration panel includes side panels 60 coupled to both sides of the front panel 40 and upper panels 50 coupled to both sides of the control panel 30. The upper panels 50 are coupled to upper portions of the side panels 60.
Meanwhile, the top plate 10 defines a top surface of the drum-type washing machine 1. The top plate 10 may be detachably coupled to the cabinet 20.
The cabinet 20 defines side and rear surfaces of the drum-type washing machine 1 to protect the internal components. Here, the side and rear surfaces of the cabinet 20 may be integrally formed. Alternatively, the side and rear surfaces of the cabinet 20 may be separated parts that will be assembled with each other by coupling members. In this case, the maintenance cost can be reduced by replacing only the damaged part.
Beads 201 each having a predetermined depth may be formed on the side surfaces of the cabinet 20 to enhance the strength of the cabinet 20.
In addition, the control panel 30 is disposed on the front-upper portion of the drum-type washing machine 1. The control panel 30 includes an input unit for inputting a washing mode and a display unit for displaying a current washing state.
Meanwhile, a width of the cabinet 20 is slightly greater than a length of the control panel 30 so that the upper panel 50 can be coupled to the both sides of the control panel 30. That is, the cabinet 20 and the control panel 30 are provided with spaces identical to sizes of the upper panels 50 so that the overall appearance can be natural when the upper panels 50 are coupled to the cabinet 20 and the control panel 30. Needless to say, the width of the cabinet 20 is greater than the front panel 40 s so that that the side panels 60 can be accurately fixed.
Here, the upper panels 50 are provided to improve the overall appearance of the drum-type washing machine 1 and formed of an ABS material.
A hook portion 501 protrudes from a lower end of the upper panel 50.
That is, the hook portion 501 includes an insertion portion 501 a extending from the lower end of the upper panel 50 by a predetermined length and a protrusion 501 b extending from the insertion portion 501 a. The protrusion 501 b extends frontward or rearward in a horizontal direction from the lower end of the insertion portion 501 a. The insertion portion 501 a may have a width that is gradually reduced as it goes downward. Therefore, the frictional resistance can be minimized when the insertion portion 501 a is inserted into a hook hole 601 that will be described later.
The hook hole 601 is formed on an upper end of the side panel 60.
That is, the hook hole 601 may have a cross-section corresponding to that of the hook portion 501.
A process for assembling the upper panel 50 with the side panel 60 will now be described with reference to the accompanying drawings.
FIGS. 2 and 3 are sectional views taken along line I-I′, illustrating an assembling process of a decoration panel.
Referring first to FIG. 2, in order to assemble the upper panel 50 to the side panel 60, the upper panel 50 is inclined frontward. In this state, the hook portion 501 formed on the lower end of the upper panel 50 is aligned with the hook hole 601 formed on the upper end of the panel 60.
That is, in a state where the hook portion 501 is inclined forward, the protrusion 501 b is inserted in the hook hole 601. Here, if the protrusion 501 b extends rearward from the insertion portion 5012 a, the upper panel 50 will be inclined rearward.
