Description

This application claims the benefit of Korean Application No. P2003-087543, filed on Dec. 4, 2003, which is hereby incorporated by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a home appliance, and more particularly, to a cabinet structure of a home appliance, such as a dryer in which a hook assembly is employed to increase the structural strength of the cabinet.
2. Discussion of the Related Art
Generally, dryers are used for automatically drying wet laundry after washing has been completed. The outer case (or cabinet) of a conventional dryer is shown in FIG. 1. Referring to FIG. 1, a cabinet B of the dryer includes a base 10, a front panel 20, side panels 30, a back cover (not shown), a top cover 50, and an upper front panel piece 6 on which a control panel is provided. The base 10 is disposed at a bottom of the dryer, and the upper front panel piece 6 is disposed at a front side of the dryer. The pair of side panels 30 is disposed at both sides of the dryer, and the back cover is disposed at a rear side of the dryer. The top cover 50 is disposed at an upper side of the dryer, and the upper front panel piece 6 is disposed above the front panel 20 below a forward edge of the top cover 50.
A typical home appliance includes large internal components, such as motors and drums, which are mounted inside the cabinet and are set in motion by operating the home appliance, and a normal amount of resulting vibration generated by, for example, a rotating drum mounted inside a dryer, may over the life of the apparatus loosen a fixing structure for joining cabinet panels. Such loosening may in turn produce more forceful vibrations an undue shaking during routine operation. Also, in the event that such a home appliance is relocated, a junction between the front and side panels of the cabinet often becomes fractured and/or loosened. At the same time, one or more of the panels may be provided with delicate components, such as electronic controls and displays, whereby a fracture with respect to the associated panel may result in a catastrophic failure of the entire apparatus.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
FIG. 2 illustrates a structure of a home appliance, such as a dryer, according to the present invention. Referring to FIG. 2, a pair of side panels 300 is disposed at both sides of an outer case of the home appliance, forming a cabinet of the dryer. A pair of flanges 210, each of which being inwardly bent at a right angle, is formed at front ends of the pair of side panels 300. The flanges 210 have a predetermined width and include at least one coupling hole 210 a. Preferably, a portion of the flanges 210 has an increased width to accommodate the coupling holes 210 a.
A panel frame piece 60 is disposed at a front side of the flanges 210. Through holes 60 a corresponding to the coupling holes 210 a are formed at both edges of the panel frame piece 60. The panel frame piece 60 and the flanges 210 are coupled together using screws, which are passed through the through holes 60 a and inserted into the coupling holes 210 a. The panel frame piece 60 is to reinforce the structural strength of the side panels 300.
A control panel (not shown) is installed in the panel frame piece 60. The control panel includes circuitry for controlling operations of the dryer and is, therefore, sensitive to deformation of the outer case of the dryer and to external impacts. The panel frame piece 60 reinforces the support structure of the control panel, thereby preventing the control panel from fracturing. The side panels 300 are assembled with the panel frame piece 60 by a screw coupling, which should be manipulated while the panel frame piece 60 is supported. Therefore, in order to facilitate the cabinet assembly, the preferred embodiment of the present invention employs a hook assembly.
In the embodiment shown in FIG. 3, the cabinet of the home appliance further includes a hook assembly for coupling a panel frame piece 60′ to the side panels 300. The hook assembly keeps the panel frame piece 60′ precisely positioned when the panel frame piece is coupled to the side panels 300.
The hook assembly includes a pair of hooks 410 and a pair of fixing holes 210 b, which are respectively provided to the front surface of each flange 210 or at both rear sides of the panel frame piece 60′. The present embodiment may employ fixing grooves instead of the fixing holes 420. Each of the hook 410 includes a support 411 and a retainer 412. The support 411 extends from a surface where the hook 410 is formed and is thus directed toward the flange 210 of the side panels 300. The retainer 412 extends from one end of the support 411, so as to be caught in the fixing hole 420.
It is preferable that the retainer 412 protrudes downward from a lower end of a distal edge of the support 411. Also, an interval between the retainer 412 and the surface having the hook 410 formed therein is nearly equal to a thickness of the flange 210 at the fixing hole 420. Accordingly, if the hook 410 is inserted into the fixing hole 420 and then pressed downward, the retainer 412 is elastically deformed, slides along a surface of the flange 210 below the fixing hole 420, and becomes seated. Accordingly, the panel frame piece 60′ is pre-assembled to the side panels 300, such that the through holes 60 a are aligned with the coupling holes 210 a, allowing the insertion of the screws.
A recess 413 is formed at the junction of the support 411 and the retainer 412. The lower edge of the fixing hole 420 resets the recess 413 and becomes clamped between the retainer 412 and the surface on which the hook is formed. The portion of the retainer 412 in contact with the edge of the fixing hole 420 is rounded. Accordingly, the retainer 412 is smoothly slid along the surface of the edge. Also, the rounded portion facilitates the insertion of the hook 410 into the fixing hole 420 and prevents surface scratching. Preferably, the retainer 412 is integrally formed with the support 411.
FIG. 4 illustrates an assembly structure according to another preferred embodiment of the present invention. In the embodiment shown in FIG. 4, a pair of hooks 410′ is formed on the front sides of the flanges 210, and a pair of fixing holes 60 b are formed in the rear surface of a panel frame piece 60″. Each hook 410′ includes a support 411′ and a retainer 412′. The support 411′ protrudes forward from a front surface of the flange 210, and the retainer 412′ extends from one end of the support 411′.
In assembling the panel frame piece 60″ to the side panels 300, the hooks 410′ are inserted into the fixing holes 420′, and then, the panel frame piece 60″ is pressed downward. At this time, recesses 413′ formed at the junctions of the supports 411′ and the retainers 412′ are seated in the fixing holes 420′. Accordingly, the upper edge of the fixing holes 420′ are fixedly inserted between the front edges of the retainers 412′ and a front surface of the flange 210. In this manner, the panel frame piece 60″ is pre-assembled to the side panels 300, such that the through holes 60 a are aligned with the coupling holes 210 a allowing the insertion of the screws.
As described above, the hook assembly can prevent the coupling of the panel frame piece to the side panels from becoming loose during a normal operation or relocation of a home appliance adopting the cabinet of the present invention. Also, since the hook assembly enables a pre-assembly of the panel frame piece with respect to the front of the side panels, the panel frame piece can be assembled to the side panels more conveniently. The damage to a control panel can be prevented by reinforcing the structural strength of the mounting surface of the control panel. When the hooks of the hook assembly are inserted into the fixing holes, the panel frame piece is temporarily fixed, and the holes for receiving the screws are aligned, thereby shortening the assembly time.
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.
