Description

Washing tank in washing machine {a washer}

The present invention relates to a washing tank of a washing machine, and more particularly, to a washing tank of a washing machine in which dehydration holes are formed in a zigzag shape on the side of the washing tank.

In general, a washing machine is a machine that removes stains on clothes by providing mechanical action using electricity.When it is put on clothes, it is removed from the fibers by the chemical action of detergent when it is put in the wash water. Because it takes time, if the water flow is forcibly generated and mechanical action such as friction or vibration can be removed quickly and easily.

1 is a cross-sectional view showing a general washing machine.

A general washing machine includes a case (2) forming an outline as shown in FIG. 1, a dehydration tank (6) supported by four hook members (10) and a damper (12) inside the case (2), A washing tank 4 rotatably installed inside the dehydration tank 6 to wash the laundry, and a washing wing 8 rotatably installed on the bottom of the washing tank 4 to form washing water in the wash water. And a clutch 14 and a motor 16 installed on the lower surface of the dehydration tank 6 to drive the washing tank 4 and the washing blade 8 in the forward or reverse direction.

In addition, a cover 18 is installed on the upper side of the case 2 to prevent laundry from being separated from the washing tank 4 and the dehydrating tank 6, and the front of the cover 18 is operated to operate the washing machine. The control unit 20 for controlling is built-in, the water supply valve 22 and the detergent box 24 for supplying the washing water and detergent into the washing tank 4 and the dehydration tank 6 at the rear of the cover 18, The detergent box housing 26 is embedded.

On the other hand, a drain valve 32 and a drain pipe 34 are installed at the lower side of the dehydration tank 6 so that the washing water can be discharged from the dehydration tank 6.

In particular, the washing tank 4 is built with a predetermined interval inside the dehydration tank 6, the auto balance mechanism 4a is installed on the upper side of the washing tank 4 to maintain the balance when the washing tank 4 rotates. do.

Here, the washing tank 4 and the washing blade 8 is rotated to form a washing water flow.

In addition, since the washing tank 4 is rotatably installed in the dehydration tank 6 and a plurality of dehydration holes are formed on the side, the washing water is connected between the dehydration tank 6 and the washing tank 4 when the washing tank 4 is rotated. Washing functions by forming a washing stream while circulating.

Conventional washing tank 4 is formed with a plurality of dehydration holes (5) on the side, as shown in Figure 2, is formed with a predetermined interval in the height and circumferential direction of the washing tank (4).

In other words, when four adjacent dehydrators are connected, they form a square shape.

By the way, since the washing tank 4 is rotated at a high speed during the dehydration stroke, rigidity must be maintained to withstand the centrifugal force of a predetermined size or more.

That is, the washing tank 4 of the washing machine according to the prior art maintains the rigidity so that the washing tank 4 can withstand the centrifugal force, and at the same time, the dehydration hole 5 must be formed on the side of the washing tank 4. There is a limit to creating a lot.

Therefore, there is a limit in improving the washing performance by the washing water flow circulated between the washing tank 4 and the dehydrating tank 6, and there is a limit in improving the rinsing and dehydrating performance.

The present invention has been made in order to solve the above problems of the prior art, it is possible to improve the washing and rinsing performance by forming a plurality of dehydration holes within the range maintaining rigidity to withstand centrifugal force of the washing tank rotated at high speed The purpose of the present invention is to provide a washing tank of a washing machine.

54: washing tank 55: dewatering

In the washing machine of the washing machine according to the present invention for solving the above problems is a washing machine in which the dehydration holes arranged in a plurality of rows and a plurality of rows spaced apart on the side of the washing tank rotatably installed in the dehydration tank in which the laundry is washed, The dehydration hole is a first row in which the dehydration holes are arranged at a predetermined interval in the longitudinal direction of the washing tank, and the second row of the dehydration holes arranged in the middle portion of the dewatering holes forming the first row is a predetermined interval in the circumferential direction of the washing tank. Are alternately placed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The washing tank 54 of the washing machine according to the present invention has a plurality of dehydration holes 55 are formed on the side as shown in FIG. 3, and the dehydration holes 55 have a predetermined interval in the height direction of the washing tank 54. The circumference of the washing tank 54 is the second row 55b in which the dehydration hole 55 is disposed in the middle of the arranged first row 55a and the dehydration hole 55 forming the first row 55a. It is arranged alternately at regular intervals in the direction.

In other words, when four adjacent dewatering holes 55 are connected to each other, a diamond shape is achieved.

And the other structure of the washing machine of this invention is the same as a general structure.

Looking at the operation of the present invention configured as described above are as follows.

First, when power is supplied to the washing machine, the control unit 20 detects an amount of laundry and supplies an appropriate amount of washing water and detergent to the washing tank 54 and the dehydration tank 6 through a water supply valve 22, and an appropriate amount. When the washing water is supplied, the washing wing 8 and the washing tank 54 is rotated, the washing administration is made.

When the washing stroke is performed as described above, the washing surface is circulated between the washing tank 54 and the dehydrating tank 8 through the dehydration hole 55 formed on the side of the washing tank 54, so that the washing surface by the dehydrating tank 8 is It becomes wider and improves washing performance.

In addition, when the washing stroke is completed and the new washing water is supplied through the water supply valve 22, even when the washing tank 54 is rotated, the washing water is rotated through the plurality of dehydration holes 55 formed on the side of the washing tank 54. By circulating between the washing tank 54 and the dehydration tank 8, the washing surface by the dehydration tank 8 is widened to improve the rinsing performance.

As such, when the rinse stroke is completed, the dehydration stroke is performed, and all the washing procedures are completed.

The washing tank of the washing machine according to the present invention constituted as described above includes a first row and a first row in which the dewatering hole is disposed at a predetermined interval in the washing tank's height direction within the washing tank within a range in which the washing tank rotated at high speed maintains rigidity to withstand centrifugal force. Since the second row in which the dehydration holes are arranged in the middle part of the dehydration holes forming one row are alternately formed at regular intervals in the circumferential direction of the washing tank, the more dewatering holes formed in the washing tank are circulated between the washing tank and the dehydrating tank. There is an advantage to improve the washing and rinsing performance by forming a.
