Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a washing machine.
2. Description of the Related Art
Generally, a drum type washing method performs a washing cycle using frictional force between the laundry and a drum rotating by receiving driving force from a motor with detergent, washing water, and the laundry inserted into the drum. The drum type washing method has some advantages that can prevent the laundry from being tangled, so that fabrics of the laundry are not damaged. Also, the drum type washing method has an effect of beating and rubbing the laundry.
An installation structure of a control panel assembly of a related art drum type washing machine will now be described with reference to the accompanying drawings.
FIG. 1 is a schematic perspective view of an outer appearance of a general drum type washing machine. The control panel assembly 50 is formed on a front upper portion of a cabinet 1 forming an outer appearance body. The control panel assembly 50 includes a plurality of buttons 21 for a user to input functions to control a washing cycle and a display screen 22 for displaying a remaining time.
A tub (not shown) capable of storing washing water is installed inside the cabinet 1 and the tub accommodates a drum (not shown) receiving the laundry.
FIG. 2 is an exploded perspective view of a related art control panel assembly.
Referring to FIG. 2, a related art control panel assembly 50 includes the control panel 51, an upper deco 53 that surrounds an outer circumference of the control panel 51, and a panel frame 55 attached on a rear surface of the control panel 51.
A plurality of electronic components (not shown) are mounted within the control panel 51. An operating knob 24 is installed on a front surface of the control panel 51 to connect to the electronic components and to allow a user to directly adjust operation of the drum type washing machine.
Hereinafter, a coupling structure of the control panel assembly according to the related art will be described.
Referring to FIG. 3, the panel frame 55 is coupled to the upper deco 53 and the control panel 51 is coupled to the panel frame 55 coupled to the upper deco 53.
Referring to FIG. 4, a lower portion of the control panel 51 is fixed to a lower portion of the panel frame 55, and an upper portion of the control panel 51 is rotated and fixed to an upper portion of the panel frame 55 such that a circumference of the control panel 51 is surrounded by the upper deco 53.
Referring to FIG. 5, to fix the upper portion of the control panel 51 to the upper portion of the panel frame 55 by rotating the upper portion of the control panel 51, it is preferable that a predetermined gap G is formed between a top lower surface portion of the upper deco 53 and an upper surface portion of the control panel 51 for rotation of the control panel 51.
Assembling of the control panel assembly is completed through this above process.
However, the assembled structure of the control panel assembly has problems below.
That is, washing water penetrates through the gap G formed between the upper surface portion of the control panel 51 and the top lower surface portion of the upper deco 53. Therefore, the penetrating washing water flows into electronic components (not shown) mounted within the control panel 51 to damage the electronic components.

SUMMARY OF THE INVENTION

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.
FIG. 6 is a perspective view of an assembled state of a control panel assembly according to an embodiment of the present invention. FIG. 7 is an exploded perspective view of a control panel assembly according to an embodiment of the present invention. FIGS. 8 to 9 are perspective views explaining an assembly process of a control panel assembly according to an embodiment of the present invention.
Referring to FIG. 6, a drum type washing machine according to an embodiment of the present invention includes a control panel 110, an upper deco 130, a panel frame 150, a first coupling unit, and a second coupling unit.
A knob and a variety of electronic components are installed in the control panel 110, and the upper deco 130 is installed to closely attach and surround both sides and an upper surface of the control panel 110. The panel frame 150 is coupled to a rear surface of the control panel 110 on which the upper deco 130 is installed. The first coupling unit couples the control panel 110 to the upper deco 130 and the second coupling unit couples the control panel 110 to the panel frame 150.
Referring to FIG. 7, the first coupling unit has a plurality of first fixing holes 210 and a plurality of first fixing protrusions 230. The first fixing hole 210 is formed in the control panel 110. The first fixing protrusion 230 is formed on the upper deco 130 to correspond to each of the first fixing holes 210 and coupled to each of the first fixing holes 210.
The second coupling unit has a plurality of hooks 310, a plurality of hook holes 350, a plurality of the second fixing protrusions 330, and a plurality of the second fixing holes 370.
The hook 310 is formed on a lower end portion of the control panel 110 and the hook hole 350 is formed in a lower end portion of the panel frame 150 to correspond to each of hooks 310 and couple to the each of hooks 310. The second fixing protrusion 330 is formed on a rear surface of the control panel 110 and the second fixing hole 370 is formed in the panel frame 150 to correspond to each of the second fixing protrusion 330 and couples to each of the second fixing protrusions 330.
Although a height H1 of the control panel 110 according to an embodiment of the present invention is lower than a height H2 of the upper deco 130, it is preferable that a top surface of an upper side portion of the control panel 110 has a height capable of being attached to a bottom surface of a lower side portion of the upper deco 130 after coupling to each other.
This is to minimize a gap formed during a process of assembling the control panel 110 and the upper deco 130.
In an assembly structure of the control panel assembly according to an embodiment of the present invention, it is preferable that the panel frame 150 is coupled to the control panel 110 coupled to the upper deco 130 after coupling the upper deco 130 to the control panel 110 so as to minimize the gap (that is a related art problem) formed between the control panel 110 and the upper deco 130.
Hereinafter, an assembling process of the control panel assembly and its resulting effect will be described.
Referring to FIG. 7, the control panel 110 is coupled to the upper deco 130.
The first fixing protrusion 230 formed on the upper deco 130 is inserted into the first fixing hole 210 formed in the control panel 110 to couple to each other.
Referring to FIG. 8, the panel frame 150 is coupled to the control panel 110 on which the upper deco 130 is installed.
The hook 310 formed on a lower side portion of the control panel 110 is inserted into the hook hole 350 formed in a lower side portion of the panel frame 150.
The second fixing protrusion 330 formed on a rear surface of the control panel 110 is inserted into the second fixing hole 370 formed in the panel frame 150 to couple to each other.
Assembling of components of the control panel assembly is completed through this process.
The height HI of the control panel 110 is lower than the height H2 of the upper deco 130. Also, the top surface of the upper side portion of the control panel 110 has the height capable of being attached to the bottom surface of the lower side portion of the upper deco 130. The gap formed between the control panel 110 and the upper deco 130 according to the related art can be minimized by assembling the control panel 110 and the upper deco 130 before the panel frame 150.
Therefore, the present invention can prevent electronic components from being damaged by penetration of washing water through the gap between the control panel 110 and the upper deco 130.
According to the present invention, the gap formed between the control panel and the upper deco can be minimized by modifying the assembly structure of the control panel assembly to prevent the washing water from penetrating into an inside of the control panel, thereby protecting the electronic components mounted within the control panel from the washing water.
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.
