The present invention relates to a washing machine, and more particularly, to a heater coupling structure and a coupling method of the washing machine that can increase the coupling reliability of the reservoir and the heater coupled thereto.

In general, a washing machine is provided with a reservoir in an inner space of a cabinet. The reservoir is supported by a damper connected to the upper part of the cabinet, and wash water is stored therein. In addition, the washing tank is rotatably installed in the reservoir. In detail, a plurality of through-holes are formed on the bottom and side of the washing tank, so that the wash water stored in the storage tank freely flows between the washing tank and the storage tank to remove dirt from the laundry.

On the other hand, the bottom surface of the reservoir is installed a heater for heating the wash water to make hot water. Therefore, even if cold water is introduced into the reservoir in winter, when the heater is operated, it is heated to an appropriate temperature for washing, so that it is not necessary to connect the tap with the hot water discharged separately.

The conventional technical contents of the reservoir equipped with the heater functioning as described above are described in detail in Korean Patent Application Publication No. 10-2003-0055973 filed by the present applicant.

Generally, however, the reservoir is a plastic injection which is of low strength compared to the heater and the bolt. Therefore, as the stress generated as described above is continuously applied to the inside of the reservoir, a crack is generated in the reservoir portion to which the heater is coupled. Then, there is a disadvantage in that the product reliability of the washing machine is greatly reduced, such as leakage of wash water through the crack.

An object of the present invention is to provide a heater coupling structure of a washing machine and a coupling method thereof, by improving a coupling structure for coupling a heater to a reservoir, and preventing the occurrence of cracks in the reservoir.

The heater coupling structure of the washing machine according to the present invention includes a heater capable of heating wash water; A water tank having a heater insertion hole into which the heater is inserted, and an insertion hole forming part forming the heater insertion hole; A sealing member for sealing between the heater and the reservoir; And a reinforcing member disposed between the insertion hole forming portion and the sealing member to reinforce the strength of a portion of the water tank facing the sealing member.

The heater coupling method of the washing machine according to the present invention includes a water reservoir having a heater, a heater insertion hole into which the heater is inserted, an insertion hole forming portion forming the heater insertion hole, and a sealing member sealing the space between the heater and the water reservoir; Providing a reinforcing member for reinforcing the strength of a portion of the water tank facing the sealing member; Disposing the reinforcing member between the insertion hole forming portion and the sealing member; Inserting the heater into the heater insertion hole; And sealing between the heater and the reinforcing member by the sealing member.

According to the heater coupling structure and the coupling method of the washing machine according to the present invention, the reinforcing member is disposed between the sealing member and the water reservoir, whereby the sealing member presses the reinforcing member in direct contact therewith. Then, the pressure generated by the compression in the sealing member is transferred to the high-strength reinforcing member, absorbed in the reinforcing member, and may not be transmitted to the reservoir. Therefore, since the stress generated inside the reservoir can be reduced, it is possible to reliably seal between the heater and the reservoir, and at the same time prevent cracks that can be generated in the reservoir by the sealing member.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the spirit of the present invention is not limited to the embodiments presented, and other embodiments included within the scope of other inventive inventions or the scope of the present invention can be easily made by adding, changing, or deleting other elements. I can suggest

In addition, a heater insertion hole 191 for inserting the heater 200 is formed in the bottom surface of the reservoir 190. In detail, the heater insertion hole 191 is formed to be embedded in a predetermined depth at the bottom of the reservoir 190 to prevent penetration of moisture or wash water into the terminal portion of the heater 200. .

In addition, the heater 200 accommodated in the heater seating groove 120 is formed having a predetermined diameter and length, the heater pipe 201 is bent a plurality of times at a predetermined position and are formed at both ends of the heater pipe. A power connection part 203 is electrically connected to the heater pipe 201 to apply power.

In addition, the heater 200 is a sealing member 310 is inserted through the power connection 203. And, before the sealing member 310 is inserted, the pressing plate 206 for pressing the sealing member 310 is inserted first. In addition, the rear side of the sealing member 310 is recessed to a predetermined depth so that the sealing member 310 is seated, and a sealing case 202 is inserted to prevent the wash water from leaking from the heater insertion hole 191. . Here, the sealing case 202 is strongly adhered to the outer wall of the reservoir 190 by a fastening member which will be described later.

Meanwhile, the pressing plate 206 and the sealing case 202 are tightly tightened by the assembly bolt 205 and the assembly nut 204 passing through the central portion of the pressing plate 206. In detail, as the assembly nut 204 threaded to the outer circumferential surface of the assembly bolt 205 is tightened, the sealing member 310 is subjected to a strong compressive force between the pressing plate 206 and the sealing case 202. Will receive. Here, the sealing member 310 may be a material having a predetermined elastic force and flexibility, preferably a rubber material.

In more detail, the sealing member 310 is the same shape or slightly smaller than the heater insertion hole 191, it is easily inserted into the heater insertion hole 191. However, the thickness of the sealing member 310 is formed thicker than the thickness of the reservoir (190).

Here, when the sealing member 310 receives a compressive force by the assembly bolt 205 and the assembly nut 204, the upper portion of the sealing member 310 is extended to the inner peripheral surface of the reservoir 190 as shown. . In addition, an area of the sealing member 310 is extended to be wider than an area of the heater insertion hole 191. Therefore, the sealing member 310 is spread sideways by the compressive force, thereby completely sealing the heater insertion hole 191, the washing water leakage to the heater insertion hole 191 is eliminated.

Meanwhile, as described above, the heater pipe 201 of the heater 200 is a conductor having a predetermined diameter and length, and is bent and formed a plurality of times. Here, the length and the number of bending of the heater pipe 201 may be bent a suitable number of times according to the length of the heater pipe 201 required.

On the other hand, according to the present invention, the high strength reinforcing member (300 of Figure 3) and the sealing member 310 in direct contact, while reducing the stress in the reservoir 190, while the heater 200 and the reservoir ( 190) is sealed. Then, a crack that may be generated due to the coupling of the heater 200 in the reservoir 190 may be prevented. This will be described later.

3 is a vertical cross-sectional view showing a heater coupling structure of the washing machine according to the present invention.

Referring to FIG. 3, the heater 200 coupling structure of the washing machine reservoir 100 according to the present invention includes a heater 200 capable of heating wash water inside the reservoir 100, and the heater 200 is inserted therein. It is provided with a reservoir (190). In addition, the heater 200 coupling structure includes a sealing member 310 that seals between the heater 200 and the reservoir 190. In addition, the heater 200 coupling structure further includes a reinforcing member 300 to reinforce the strength of the reservoir 190.

The heater 200 includes a sealing case 202 formed at an end portion of a heater pipe that directly contacts the washing water and heats the washing water, and a pressing plate 206 spaced apart from the sealing case 202 at a predetermined interval. . In order to simplify the manufacturing process, the heater 200 may form an assembly with the sealing member 310. The heater 200 is coupled to the sealing case 202, the heater pipe, the pressing plate 206, and the sealing member 310 by separate assembly nuts 204 and assembly bolts 205. Can be a single article.

The reservoir 190 is provided with a heater insertion hole 191 into which the heater 200 is inserted, and an insertion hole forming unit 192 forming the heater insertion hole 191.

The sealing member 310 seals between the heater 200 and the reservoir 190. As described above, the sealing member 310 may be a component of the heater 200 by the assembly bolt 205 and the nut 204.

The reinforcing member 300 is made of a material having a predetermined strength. The reinforcement member 300 formed as described above is disposed between the insertion hole forming portion 192 and the sealing member 310 to face the sealing member 310 of the reservoir 190 in detail. The strength of the hole forming unit 192 is reinforced. Then, the pressure generated in the sealing member 310 compressed to seal between the heater 200 and the reservoir 190 is transmitted to the reinforcing member 300 in direct contact with the sealing member 310. . Therefore, since the pressure generated by the sealing member 310 may be absorbed by the reinforcing member 300 and may not be substantially transmitted to the insertion hole forming portion 192, the pressure may be applied to the inside of the insertion hole forming portion 192. The stress corresponding to the pressure is reduced. Therefore, cracks that may occur in the reservoir 190 may be prevented by the sealing member 310.

Here, the reinforcing member 300 performs a function of absorbing the pressure transmitted from the sealing member 310, so that the above function can be performed smoothly, the reinforcing member 300 has a self-closed structure It is desirable to achieve. For the same reason as described above, in this embodiment, the portion of the reinforcing member 300 facing the sealing member 310 forms a closed curved surface.

On the other hand, the reinforcing member 300 may be a separate unit from the reservoir (190). In this case, a structure that can be sealed between the reinforcing member 300 and the reservoir 190, in particular the insertion hole forming portion 192 is required. Therefore, the reinforcing member 300 may be adhered to the reservoir 190 by a predetermined adhesive part 320. Here, the adhesive part 320 may be made of a material such as rubber and silicon.

In addition, the reinforcing member 300 may be integrally formed with the reservoir 190. In this case, the reinforcing member 300 and the reservoir 190 may be sealed without performing a separate process such as adhesion. In this case, a method of insert-injecting the reinforcing member 300 into the reservoir 190 may be proposed.

Referring to FIG. 4, the reinforcing member 300 used in the heater 200 coupling structure according to the present invention may include a first annular portion 301 and a second annular portion 302 protruding from the support annular portion 301. ). The interior of the first annular portion 301 and the second annular portion 302 is penetrated to form a sealing member insertion hole 303.

The first annular portion 301 is in contact with the insertion hole forming portion 192 of the reservoir 190 to support the reinforcing member 300.

The second annular portion 302 is a portion inserted into the insertion hole forming portion 192, and is disposed between the sealing member 310 and the insertion hole forming portion 192 by the insertion as described above. As the second annular portion 302 is disposed as described above, a reinforcing function of the reinforcing member 300 with respect to the reservoir 192 may be performed.

The sealing member insertion hole 303 is a portion into which the sealing member 310 is inserted. As the sealing member 310 is inserted into the sealing member insertion hole 303 as described above, the sealing member 310 and the reservoir 192 are indirectly coupled. Therefore, the phenomenon in which the pressure generated in the sealing member 310 is directly transmitted to the reservoir 192 can be prevented.

As described above, the reinforcing member 300 formed as described above is a portion for reinforcing the strength of the insertion hole forming portion 192 of the reservoir 190 and is made of a material having a predetermined strength. In this embodiment, the reinforcing member 300 is made of a metallic material.

Hereinafter, a heater coupling method of the washing machine according to the present invention will be described.

First, the heater 200, the reservoir 190, a sealing member 310 for sealing between the heater 200 and the reservoir 190, and a reinforcement member 300 having a predetermined strength are provided. . As described above, the reservoir 190 is provided with a heater insertion hole 191 into which the heater 200 is inserted, and an insertion hole forming unit 192 forming the heater insertion hole 191.

Then, the reinforcing member 300 is disposed between the insertion hole forming portion 192 and the sealing member 310. In this embodiment, the reinforcing member 300 is disposed in such a manner that the reinforcing member 300 is inserted into the insertion hole forming portion 192.

Thereafter, the heater 200 is inserted into the heater insertion hole 191. In detail, the heater 200 is inserted into the sealing member insertion hole 303 inside the reinforcing member 300 inserted into the heater insertion hole 191.

Then, the sealing member 310 is sealed between the heater 200 and the reinforcing member 300. Such sealing is performed by compression of the sealing member 310 by tightening the assembly nut 204 and the assembly bolt 205. Then, the sealing member 310 presses the reinforcing member 300 in direct contact therewith. Therefore, the pressure of the sealing member 310 may be absorbed by the reinforcing member 300 of high strength, and may not be transmitted to the reservoir 190. Then, as described above, the stress generated in the reservoir 190 can be reduced.

As described above, according to the present invention, while reducing the stress generated in the reservoir 190, in detail, the insertion hole forming portion 192 to a small value, it is reliably between the heater 200 and the reservoir 190. It can be sealed. Therefore, cracks that may occur in the reservoir 190 may be prevented by the sealing member 310.

On the other hand, in order to seal between the reinforcement member 300 and the reservoir 190, after the reinforcement member 300 is disposed, the step of adhering the reinforcement member 300 to the reservoir 190 is further performed. can do.

According to the heater coupling structure and the coupling method of the washing machine according to the present invention having the above configuration, the reinforcing member is disposed between the sealing member and the water reservoir, so that the sealing member pressurizes the reinforcing member in direct contact therewith. Then, the pressure generated by the compression in the sealing member is transferred to the high-strength reinforcing member, absorbed in the reinforcing member, and may not be transmitted to the reservoir. Therefore, since the stress generated inside the reservoir can be reduced, there is an effect that the cracks that can be generated in the reservoir by the sealing member can be prevented at the same time while reliably sealing between the heater and the reservoir.
