DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

Reference will now be made in detail to the preferred embodiment(s) of the present invention, examples of which are illustrated in the accompanying drawings. Throughout the drawings, like elements are indicated using the same or similar reference designations where possible. [0028]
FIG. 1 is a perspective view of a washing machine according to one embodiment of the present invention and FIG. 2 is a cross-sectional view of a washing machine according to one embodiment of the present invention. [0029]
Referring to FIG. 1 and FIG. 2, a washing machine according to the present invention includes a [0030] case 2, a tub 6, a drum 8, and a driving motor (not shown in the drawing).
The [0031] case 2 forms an exterior of the washing machine, and a door 4, via which a laundry is inputted/outputted, is provided to a front side of the case 2. The tub 6 is provided in the case 2 to hold water and detergent. The cylindrical drum 8 is provided in the tub 6. The drum 8 holds laundry and is rotated by the driving motor. In doing so, the laundry is washed by the friction between the laundry and current.
A multitude of [0032] holes 9 are formed at a circumference of the drum 8, and the water communicates between the tub 6 and the drum 8 to generate the current.
Meanwhile, the [0033] case 2 includes a cabinet 10, a front panel 12, a top plate 16, and a base 18.
The [0034] front panel 12 is provided to a front side of the cabinet 10, and an opening 12 a is formed at a central part of the front panel 12. Moreover, a door 4 is rotatably installed in the vicinity of the opening 12 a.
The [0035] top plate 16 is provided over the cabinet 10, and a control panel 14 for controlling an operation of the washing machine is provided to a rear part of an upper surface of the top plate 16. And, the base 18 is provided under the cabinet 10 to support a bottom of the washing machine.
An [0036] inlet hose 20 for supplying water is provided under the to plate 16. The inlet hose 20 is connected to a detergent box 24 provided to one side of a front part of the top plate 16. The water supplied via the inlet hose 20 passes through the detergent box 24 to be mixed with detergent. The water mixed with the detergent is led to the tub 6 via an inlet bellows 26.
Meanwhile, a plurality of storing parts for storing the detergent are formed inside the [0037] detergent box 24. And, a cover 30 is provided to a topside of the detergent box 24 to open/close the storing parts 23. The cover 30 is rotatably fixed to a cover frame 40 that is assembled to the detergent box 24. In this case, the cover 30 is coupled to the cover frame 40 using a hinge.
An operation of the washing machine according to the present invention is explained as follows. [0038]
First of all, after the detergent is put in the storing [0039] parts 23, the cover 30 is revolved to cover topsides of the storing parts 23. The laundry is put in the drum 8, and the washing machine is then driven so that water flows in the detergent box 24. The water passes through the storing parts 23 to be mixed with the detergent. The water mixed with the detergent then flows in the tub 6 via the inlet bellows 26. Once the water mixed with the detergent fills the tub 6 with an appropriate amount, the laundry is soaked in the water.
Subsequently, the driving motor rotates the [0040] drum 8 so that the dirt or filth attached to the laundry undergoes friction with the water and detergent to be separated from the laundry. After completion of washing, rinsing and dewatering are executed in turn.
FIG. 3 is a perspective view of an assembly of a detergent box and a cover frame according to another embodiment of the present invention, FIG. 4 is a perspective view of a detergent box loaded on a top plate according to the present invention, and FIG. 5 is a perspective view of a cover frame installed on a top plate according to the present invention. [0041]
Referring to FIG. 3 and FIG. 4, an opening [0042] 16 a is formed at the top plate 16. The detergent box 24 is loaded on the opening 16 a to be caught on a hanging means. In this case, the hanging means is a hook for example.
[0043] Hooks 25 a are provided to the detergent box 24 to protrude from lateral sides of the detergent box 24. A bent part 17 b bent downward is provided to an inside of the opening 16 a, and holes 17 a are formed at the bent part 17 b to have the hooks 25 a inserted therein.
The [0044] hooks 25 a are formed at front and rear sides of the detergent box 24, and the holes 17 a are formed to correspond to the hooks 25, respectively. Once the hooks 25 a are coupled to the holes 17, respectively, the detergent box 24 is securely fixed to the opening 16 a.
Meanwhile, the [0045] detergent box 24 is inserted to lie under the opening 16 a. In doing so, the hooks 25 are inserted in the holes 17 a to be fixed thereto.
The [0046] hooks 25 a formed at the detergent box 24, as shown in FIG. 4, are inserted in thee holes 17 a formed at the bent part 17 b, respectively. Moreover, the bent part is 17 b reinforces rigidity of a neighbor part 16 of the opening 16 a.
Meanwhile, the [0047] cover frame 40 is provided to the topside of the detergent box 24. And, the cover 30 is rotatably installed at one side of the cover frame 40. The cover frame 40 is loaded on the neighbor part 16 b of the opening 16 a. Screws 50 are then screwed in the cover frame 40 to fix the cover frame 40 to the detergent box 24.
Holes, in which the [0048] screws 50 are respectively locked, are explained as follows.
Referring to FIG. 3, [0049] first bosses 25 c having first holes 25 b inside protrude upward from front and rear sides of the detergent box 24, respectively, and second bosses 41 b having second holes 41 a inside protrude downward from the cover frame 40 to correspond to the first bosses 25 c, respectively.
One ends of the [0050] second bosses 41 b are inserted in the first holes 25, respectively, whereby the holes 41 a and 25 b coincide with each other with ease. Each of the screws 50 penetrates the corresponding holes 41 a and 25 b to be locked. Hence, the cover s frame 40 and the detergent box 24 are more easily fixed to the neighbor part 16 of the opening 16.
FIG. 6 is a cross-sectional view of first and second bosses in FIG. 3. [0051]
Referring to FIG. 6, a diameter of an upper [0052] inner circumference 25 e of each of the first holes 25 b is greater than that of a lower inner circumference of the corresponding first hole 25 b. Hence, one end of the corresponding second boss 41 b is inserted in the upper inner circumference of the corresponding first hole 25 b, and the corresponding screw 50 is screwed into the lower inner circumference of the corresponding first hole 25 b. Moreover, a diameter of an inner circumference 41 e of the second boss 41 b is greater than that of the screw 50.
Namely, interior screws coupled to the [0053] screws 50 are formed on the lower inner circumferences 25 of the first holes 25 b, respectively, and the screws 50 are coupled to the interior screws, respectively. In doing so, the neighbor part 16 b of the opening 16 a is strongly clamped between the cover frame 40 and the hooks 25 a of the detergent box 24. Namely, the detergent box 24 and the cover frame 40 clamp the top plate 16 to be fixed thereto.
Accordingly, the washing machine according to the present invention has the following advantages or effects. [0054]
First of all, lees efforts are made to alignment between the holes of the detergent box and cover frame. Namely, while the hooks of the detergent box are caught on the top plate, the first bosses are inserted in the second bosses. The screws are then coupled to fix the detergent box to the top plate simply. [0055]
Secondly, the top plate is clamped between the detergent box and the cover frame by the screw coupling, the detergent box is more securely fixed to the top plate. [0056]
Thirdly, the bent part having the holes for the hooks reinforces the support structure for fixing the detergent box. [0057]
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover such modifications and variations, provided they come within the scope of the appended claims and their equivalents. [0058]
