The present invention relates to a device designed to simplify the assembly process while reducing the type of parts to be assembled to the outside in assembling the support plate and the rear tube and the lower base on the outer box of the washing machine.

In general, a washing tank with a built-in washing tank is installed inside the outer box of the washing machine so that washing and dehydration work can be carried out. The upper plate, which is provided with a cover and a control panel, is attached to the upper part of the outer box to remove laundry and various kinds of washing machines. It is configured to control the function.

When the reservoir is installed inside the trauma, it is mainly to be fixed to the lower four sides of the reservoir by using four hook rods. Such a storage tank looks like a technical configuration that is fixed to the outer box of the washing machine by the hook rod.

Fix and install the support plate with hook hole on the upper side of the outer coder, and fix the upper part of the hook rod to the hook hole, and then insert the lower part of the hook rod with the buffer device into the lower side of the water tank. The hanging rod is fixed to the trauma at regular intervals, and is fixed at a fixed interval. The shock absorber at the bottom of the hanging rod is used to alleviate the vibration of the water tank generated during washing. It is not configured to be delivered.

However, as described above, the support plate fixed to the four corner corners of the trauma top is mainly contacted with the corner of the trauma and then welded or caulked, and the upper and lower thick plates are respectively provided on the upper and lower portions of the space cut in the rear of the trauma. After welding or caulking, assembling the thick plate in the opening formed between the upper plate and the lower plate and coupling the lower base to the bottom portion of the outer shell, such a conventional assembly structure has a considerable problem as described in detail as follows.

first; Conventionally, since parts such as a support tube and a thick plate, an upper plate, a lower plate, and a lower base attached to the outer side of a washing machine are separately manufactured and added, the number of parts increases considerably and the cost of the product increases. There is a dead end.

second; As there are many parts attached to the outer casing of the washing machine as described above, there is an excessive disassembly time consumed for the assembly thereof, resulting in a decrease in productivity compared to the amount of work.

Third; The support tube and the upper plate and the lower plate assembled on the outer shell are to be welded or caulked, and there is a closed end that requires a separate facility according to welding or caulking.

Therefore, an object of the present invention is to provide a coupling structure in which the assembly structure of the various parts to be assembled on the outer shell of the washing machine is simple and the number of parts is reduced as described in detail with reference to the accompanying drawings.

That is, the upper back plate 21 having the stepped portions 21a formed on both sides is formed on the rear surface of the support plate 20 on which the hook holes 22 are formed in all directions in coupling the support plate, the rear plate and the lower base to the outer box 10 of the washing machine. The rear cover 40 and the rear cover 40 are formed in the central space 11 on the rear of the outer box 10 by integrally forming the lower rear plate 31 having the stepped portions 31a formed on both sides of the lower base 30. In the drawings, reference numeral 50 in the drawing is a screw hole perforated in each part, and 21b and 31b are formed on the rear surface of the screw hole 50 of the upper and lower rear plates 21 and 31. Formed boss.

The present invention formed as described above has a support plate 20, a rear cover 40, and a lower base 30 separated from the outer box 10 of the washing machine in the open upper part of the box 10 as shown in FIG. 1. When the support plate 20 is inserted, the upper periphery of the support plate 20 is placed on the bent periphery of the upper part of the trauma 10, and the upper rear plate 21 formed at the rear of the support plate 20 is the rear of the trauma 10. It is inserted in the upper portion of the space portion 11 formed notched in the center, wherein the support plate 20 and the upper rear plate 21 and the periphery of the outer periphery and the back of the outer thread 10 (50) is a natural coincidence bar By simply fastening the screws, the support plate 20 is firmly assembled to the outer box 10.

Thereafter, the lower base 30 is inserted into the bottom of the trauma 10, and the lower rear plate 31 integrally formed on the rear of the lower base 30 is inserted into the lower portion 11 of the rear of the trauma 10. When each screw is screwed into the threaded hole 50 of the part, the lower base 30 is firmly fixed to the outer box 10, and thus, the support plate 20 and the upper rear plate (11) in the rear space 11 of the box 10. 21 and the lower rear plate 31 of the lower base 30 is coupled to the upper and lower rear plates 21, 31 if the opening is formed between this is to screw the rear cover 40.

Therefore, the upper plate 21 and the lower plate 31 integrally formed on the support plate 20 and the lower base 30 are screwed together when assembling the support plate 20 and the lower base 30. And the caulking operation is eliminated altogether, it is not necessary to provide a separate facility for the welding and caulking business, and the parts are simplified to simplify the assembly process.

In addition, the upper plate 21 and the lower plate 31 are formed on both sides of the upper plate 21 and the lower plate 31 so that the upper plate 21 and the lower plate 31 have a space 11 at the rear of the outer box 10. The tip of the trauma 10 is inserted into the stepped portions 21a and 31a when being inserted into the upper surface 21 and the bottom of the lower plate 31 so that the surface of the trauma 10 coincides with the exterior. In this case, it is important to form the height of the stepped portions 21a and 31a at a height corresponding to the thickness of the trauma 10.

Thus, the screw hole 50 and the stepped portion 21a of the outer box 10 in the state where the front end of the outer box 10 is inserted into the stepped portions 21a and 31a of the upper and lower plates 21 and 31. The tightening operation of the screw is very hardened by the bosses 21b and 31b protruding from the rear of the screw hole 50 drilled in 31a).

The present invention is to manufacture the support plate 20 and the lower base 30 coupled to the outer box 10, the upper plate 21 and the lower plate 31 are integrally injection-molded bar parts compared to the prior art to reduce the number of parts As a result, the assembly process is shortened and productivity is improved, and additional equipment required for welding and caulking is not required. Therefore, a very useful design that can improve productivity due to cost reduction and assembly time is reduced. will be.
