Throughout the drawings, like elements are indicated using the same or similar referencedesignations where possible.First of all, a drum-type washing machine according to the present invention is explained in detail by referring to FIGS. 2 to 6 as follows. FIG. 2 is a perspective diagram of a drum-type washing machine according to the present invention. Referring to FIG. 2, an outer case 1 of a drum-type washing machine according to the present invention includes a cabinet 2, a cabinet cover 14, and a top plate 29. The cabinet cover 14 is provided to a front side of the cabinet 2, and an opening isformed in a central part of the cabinet cover 14. And, a door 16 is provided to a rim of the opening to open/close the opening.A tub 4 is provided within the outer case 1, and a drum 6 is rotatably provided within the tub 4. At least one lifter 8 is provided on an inner circumference of the drum 6 to lift a laundry to fall by gravity. And, a bearing housing 10 isprovided in rear of the tub 4. Moreover, a motor is loaded in the bearing housing 10 to rotate the drum 6. Meanwhile, a plurality of holes 29a is formed at a bottom side of the top plate 29, and a plurality of holders 2a is provided to an upper end ofthe cabinet 2. By inserting the holders 2a to the corresponding holes 29a, respectively, the top plate 29 is fixed to a topside of the cabinet 2.A control panel 22 controlling an operation of the washing machine is provided over the cabinet cover 14. An inlet hose 22, inlet valve 24, and detergent box 26 for supplying water or detergent to the tub 4 are provided in rear of the controlpanel 22. A base 20 is provided to a bottom side of the washing machine. And, a drain pump (not shown) and drain hose (not shown) are provided on the base 20 to discharge the water. Meanwhile, a topside of the washing machine is covered with the topplate 29.FIG. 3 is a layout of a bottom side of a top plate of a drum-type washing machine according to one embodiment of the present invention. Referring to FIG. 3, the top plate 29 includes a top plate board 30, a front frame 32, and a rear frame 34. The front frame 32 is provided to a front side edge of the top plate board 30, and the rear frame 34 is provided to a rear side edge of the top plate board 30. In order to reinforce rigidity (or enhance the structural strength) of the top plate board30, the front and rear frames 32 and 34 protrude in a bottom direction of the top plate board 30. In this case, the front and rear frames 32 and 34 are formed of a synthetic resin based material by injection molding.Meanwhile, both ends of the front frame 32 are connected to both ends of the rear frame 34 by a pair of connecting members 36, respectively. Preferably, the connecting member 36 is a staple. Namely, both of the confronting ends of the front andrear frames 32 and 34 are connected to each other by a pair of the connecting members 36, respectively. Thus, the front and rear frames 32 and 34 are fixed to each other by the connecting members 36 and are then loaded on the bottom side of the topplate board 30. Thereafter, the top plate 29 is loaded on a topside of the washing machine.FIG. 4 is a magnified diagram of a top plate according to one embodiment of the present invention. Referring to FIG. 4, the front and rear frames 32 and 34 are connected by the connecting member 36. Each of the front and rear frames 32 and 34contracts or expands according to a temperature of a cold-resistant or heat-resistant test. Each of the front and rear frames 32 and 34 has a predetermined width in right-to-left direction, whereas the connecting member 36 is one-sided to connect thefront and rear frames 32 and 34. Hence, the front and rear frames 32 and 34 asymmetrically contract or expand in the connected portions, respectively, whereby a gap takes place between the connected portions of the front and rear frames 32 and 34.The connected portions of the first and second frames 32 and 34 cannot be completely fixed to each other by the connecting member 36. The farther the connected portions are left part from the connecting member 36, the wider the gap `A`increases. In order to suppress the occurrence of the gap `A`, a loading position of the connecting member 36 can be moved to a central part. Yet, the gap `A` still occurs due to an amount of the expansion or contraction occurring in a location outwarddistant from the connecting member 36. Thus, the gap `A` ruins an exterior of the rum type washing machine 1 and fails to meet user's satisfaction. Such a problem can be solved by another embodiment of the present invention.FIG. 5 is a diagram of a bottom side of a top plate of a drum-type washing machine according to another embodiment of the present invention. Referring to FIG. 5, the top plate 50 covers a topside of the drum-type washing machine 1. And, the topplate 50 includes a top plate board 60, a front frame 70, and a rear frame 80. Each of the front and rear frames 70 and 80 has a channel shape to enclose edges of the top plate board 60. Namely, the front frame 70 is provided to a front side edge ofthe top plate board 60 and the rear frame 80 is provided to a rear side edge of the top plate board 60. In this case, the front and rear frames 70 and 80 are formed of a synthetic resin based material by injection molding.Meanwhile, both ends of the front frame 70 are connected to both ends of the rear frame 80 by a pair of connecting members 90, respectively. Namely, both of the confronting ends of the front and rear frames 70 and 80 are connected to each otherby a pair of the connecting members 90, respectively. Simultaneously, a pair of the connecting members 90 fixes the frames 70 and 80 to the top plate board 60 as well. Preferably, the connecting member 90 is a staple.Referring to the magnified diagram in FIG. 5, a fixing guide 100 is provided to a location leaving a predetermined distance from the corresponding connecting member 90 to fix the corresponding ends of the frames 70 and 80 to each other and toguide a corresponding assembly.FIG. 6 is a perspective diagram of a top plate according to another embodiment of the present invention. Referring to FIGS. 5 and 6, insertion parts 72 and 82 are provided to inside edges of the front and rear frames 70 and 80 to have the topplate board 60 inserted therein. While the top plate board 60 is inserted in the insertion parts 72 and 78, the connecting member 90 is installed. In doing so, the front frame 70, rear frame 80, and top plate board 60 are simultaneously fixed to eachother by the connecting member 90.The fixing guide includes a first guide 92 and a second guide 94. The first guide 92 protrudes from one of the frames 70 and 80, and the second guide 94 provided to the other frame is coupled to the first guide 92. In doing so, the first guide92 is inserted in a recess 95 formed on a lateral side of the second guide 94 and is then held by the second guide 94 to be fixed thereto.In this case, a tilted part 92b and a coupling part 92a are provided to the first guide 92. The coupling part 92a protrudes from a tip of the first guide 92 in a direction confronting the second guide 94. The tilted part 92b is formed at aportion of the coupling part 92a confronting the second guide 94 to be tilted in an inserting direction. The coupling part 92a is inserted in the recess 95 along the second guide 94 and is then held by a protruding part 94a formed at the second guide 94to be fixed thereto.Namely, the second guide 94 is formed to confront the first guide 92. And, the protruding part 94a is formed at a tip of the second guide 94 to hold the coupling part 92a of the first guide 92. In this case, the first guide 92 has a shapedecreasing in width toward its tip to be easily inserted in the recess 95.A guide surface 94b, as shown in FIG. 5, is formed at the protruding part 94a to be contacted with the tilted part 92b of the first guide 92. When the first guide 92 is inserted in the recess 95, the tilted part 92b slides along the guidesurface 94b. After the coupling part 92a has been moved over the protruding part 94a, the coupling part 92a is held by the protruding part 94a to be fixed thereto. In doing so, the elastic transformation of the first guide 92 enables the coupling part92a passes through the protruding part 94a. Once the first guide 92 is restored from the elastic transformation, the coupling part 92a is finally held by the protruding part 94a. Preferably, the first guide 92 is built in one body of one of the frontand rear frames 70 and 80 and the second guide 94 is built in one body of the rest frame.An assembly process of the top plate of the drum-type washing machine according to the present invention is explained in detail as follows.First of all, a front side rim of the top plate board 60 is inserted in the insertion part 72 of the front frame 70 and a rear side rim of the top plate board 60 is inserted in the insertion part 82 of the rear frame 80. In doing so, the firstguide 92 provided to one frame 70 or 80 is inserted in the recess 95 formed at the other frame 80 or 70. And, the front and rear frames 70 are guided by the first and second guides 92 and 94 to be loaded on the correct positions, respectively.Meanwhile, once the first guide 92 is fully inserted in the recess 95 formed in the vicinity of the second guide 94, the coupling part 92a of the second guide 92 is held by the protruding part 94a provided to the second guide 94 to be fixedthereto. In this case, both ends of the front frame 70 coupled to the top plate board 60 are contacted with both ends of the rear frame 80 coupled to the top plate board 60, respectively. The connecting members 90 are provided to both of the contactedends of the front and rear frames 70 and 80 to fix to each other, respectively. Each of the connecting members is coupled to the top plate board 60 as well as connects the corresponding contacted ends of the front and rear frames 70 and 80. Hence, thefront and rear frames 70 and 80 are concretely fixed to the edges or rim of the top plate board 60 by the connecting members 90 and the fixing guides 100.Besides, in order to fix the frames 70 and 80 to the edges of the top plate board 60 more stably, a plurality of auxiliary connecting members can be coupled to the frames 70 and 80 except their contacted ends. Thus, both of the contacted ends ofthe front and rear frames 70 and 80 are stably fixed to each other by the connecting members 90 and the fixing guides 100, respectively. Even if the front and rear frames 70 and 80 contract or extract according to a temperature change during acold-resistant or heat-resistant test, the gap is prevented from occurring between the connected portions of the frames 70 and 80.Preferably, the connecting member 90 leaves a maximum distance from the fixing guide 100 in a right-to-left direction of the connected portions of the front and rear frames 70 and 80. Hence, the connecting member 90 fixes one side of theconnected portions and the fixing guide 100 fixes the other side of the connected portions, whereby the gap occurrence can be highly prevented.Accordingly, the present invention has the following advantages or effects.First of all, the frames for rigidity reinforcement of the edges of the top plate are provided to prevent the top plate from being broken or distorted by an external force. Secondly, the connected or contacted portions of the frames are coupledto each other by the corresponding connecting member and fixing guide, whereby the gap is prevented from occurring between the connected portions of the frames due to the transformation caused by the cold-resistant or heat-resistant test. Therefore, itis able to meet the consumer's satisfaction for the product. Finally, the frames are guided by the fixing guide to be coupled to each other, whereby the corresponding assembly is facilitated.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 coversuch modifications and variations, provided they come within the scope of the appended claims and their equivalents.* * * * *
