Description

Assembly structure of water tank for washing machine {ASSEMBLY STRUCTURE OF RESERVOIR FOR A WASHING MACHINE}

The present invention relates to an assembly structure of a washing tank for a washing machine, and more particularly, to an assembly structure of a washing tank for a washing machine for assembling an assembly structure of a washing tank for a washing machine using a joining means such as fusion welding.

3 shows an assembly structure of a water tank for a washing machine according to the prior art.

Referring to FIG. 3, the assembly structure of the water tank for a washing machine according to the related art includes a first body 10, a second body 15, and a packing 20.

The laundry body opening 12 is formed on the front surface of the first body 10, and a first protrusion 11 having a closed curve is formed on a radial outer circumferential surface of the rear surface of the first body 10. At this time, the first protrusion 11 is symmetrically formed with one or more first through holes 13 through which fastening means such as bolts and nuts pass.

The second body 15 has a second protrusion 16 in contact with the first protrusion 11 on a radial outer circumferential surface of the front surface in a closed curve shape. At this time, the second protrusion 16 is formed with one or more second through holes 17 through which the fastening means penetrate at a position coinciding with the first through hole 13 formed in the first protrusion 11.

The packing 20 is disposed between the first body 10 and the second body 15, and at least one third through hole 21 through which the fastening means penetrates at the same position as the first through hole 13 is formed. do.

Referring to the operation and effect of the assembly structure of the water tank for a washing machine of the prior art having the configuration as described above are as follows.

Referring back to Figure 3, when assembling the assembly structure of the reservoir for the washing machine,

When the rear surface of the first body 10 and the front surface of the second body 15 are assembled to each other, the first protrusion 11 formed on the first body 10 and the second protrusion formed on the second body 15 ( 16) are in contact with each other. In this case, the packing 20 is disposed between the first protrusion 11 and the second protrusion 16.

Next, the first through hole 13 formed in the first protrusion 11 of the fastening means, the second through hole 17 formed in the second protrusion 16, and the third through hole 21 formed in the packing 20. Through) to couple the first body 10 and the second body (15). At this time, the packing 20 is in close contact between the first protrusion 11 and the second protrusion 16 to prevent leakage to the outside of the reservoir when the washing machine operates.

By the way, the assembly structure of the water tank for a washing machine of the prior art increases the production cost by using one or more fastening means and packing when assembling the first body and the second body, washing machine by assembling the first body and the second body as a fastening means If it works, problems such as noise and vibration will occur.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to assemble the first body and the second body using a joining means such as fusion welding to reduce the parts required for assembling the water tank production costs Can reduce the cost. In addition, it is possible to reduce vibration and noise due to misassembly during the assembly work of the reservoir.

In order to achieve the above object, the assembly structure of the water tank for a washing machine of the present invention includes a first body and a second body.

The first body has a laundry inlet formed at one end thereof, and a first protrusion having a closed curve shape is formed at a radial outer circumferential surface opposite to the inlet.

One end of the second body is coupled to the driving unit, and a second protrusion having a closed curve shape is formed on the radial outer circumferential surface opposite to the driving unit.

Hereinafter, with reference to the accompanying drawings will be described in more detail with respect to the assembly structure of the reservoir for a washing machine according to an embodiment of the present invention.

1 illustrates an assembly structure of a washing tank for a washing machine, and FIG. 2 illustrates a cross section of the assembly structure of a washing tank for a washing machine.

1 and 2, the assembly structure of the water tank for a washing machine according to an exemplary embodiment of the present invention includes a first body 100 and a second body 150.

The first body 100 is a laundry inlet is formed on the front, the first projection 110 is formed on the radial outer peripheral surface of the back.

The second body 150 has a second protrusion 160 formed on a radial outer circumferential surface of the front surface in contact with the first body 100.

The operation and effects of the assembly structure of the reservoir for a washing machine according to the preferred embodiment of the present invention configured as described above will be briefly described.

Referring back to Figures 1 and 2, when assembling the first body 100 and the second body 150 using the bonding means,

First, the first protrusion 110 formed on the first body 100 and the second protrusion 160 formed on the second body 150 face each other. At this time, the center lines of the first body 100 and the second body 150 coincide with each other, and a fusion joint is installed between the first protrusion 110 and the second protrusion 160.

Next, the first protrusion 110 and the second protrusion 160 are coupled to each other.

Next, the first protrusion 110 and the second protrusion 160 are combined using thermal fusion or ultrasonic fusion. At this time, the fusion site (d) is formed between the first body 100 and the second body 150 is bonded to seal the first body 100 and the second body 150.

As described above, the assembly structure of the conventional water tank for the washing machine is assembled using the fastening water and prevents leakage by using the packing, so that the production cost is increased to produce the washing machine water tank, and the noise caused by the incorrect assembly of the fastening means or the packing. And vibration increases. Therefore, since the assembly structure of the water tank for the washing machine according to the present invention assembles the washing machine water tank using a joining means such as fusion, it is possible to reduce the production cost by reducing the number of parts, and to reduce noise and vibration.

Although the above has been described with reference to a preferred embodiment of the present invention, the present invention is not limited to these embodiments and can be variously modified and changed within the spirit and scope of the present invention shown in the claims below. Those skilled in the art will readily understand.
