Abstract

A laundry plate structure capable of improving the washing efficiency is provided on the inner wall of the washing tub of the washing machine.
A plurality of washing plates 150 protruding in a streamlined manner at regular intervals along the longitudinal direction of the washing tub 140 and a plurality of washing plates 150 protruding from the inner surface of the washing tub 140, A plurality of washing holes 141 are formed in the washing plate partitioned into both side regions based on the diaphragm.

Description

[0001] The present invention relates to a tub of a washing machine having a washing plate,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a washing tub of a washing machine, and more particularly, to a washing tub structure capable of improving laundry washing efficiency on the inner wall of the washing tub.

Generally, the washing machine 100 is provided with a driving motor 20 and a clutch 30 that transmits power of the driving motor 20 via a belt 25 to the lower portion of the outer cylinder 10 as shown in FIG.

A washing tub 40 is installed in the outer cylinder, and a pulsator 45 is installed in the center of the washing tub. The clutch 30 selectively rotates the washing tub 40 and the pulsator 45 so that the pulsator 45 is rotated in the normal and reverse directions during washing and the washing tub 40 and pulsator 45 ) At the same time.

Since the inner wall of the washing tub 40 is formed as a flat tubular shape and has a plurality of dewatering holes 41, the general washing machine constructed as above has a problem of low cleaning ability due to low friction with laundry during washing.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the above-mentioned problems, and it is an object of the present invention to provide a laundry washing machine, which is capable of increasing the friction between laundry in the longitudinal direction on the inner wall of the washing tub, And a washing machine.

To achieve the above object, according to the present invention, there is provided a washing machine having a washing tub and a pulsator installed in an outer cylinder, and a washing machine and a pulsator selectively driven by a clutch configured at a lower portion of an outer cylinder,

A plurality of washing plates protruding in a streamlined manner at regular intervals along a longitudinal direction of the washing tub; and a left and right space formed between the inner surface of the washing plate and the inner surface of the washing tub, And a plurality of washing holes are provided in the washing plate partitioned into both side regions based on the diaphragm.

The present invention relates to a washing machine comprising a plurality of washing plates protruding in a streamlined manner at regular intervals along the longitudinal direction of the washing tub on the inner wall of the washing tub, And a plurality of washing holes are provided in the washing plate divided into both side regions with respect to the diaphragm on the basis of the diaphragm and the washing hole in the left and right rotations of the washing water in the washing tub, , The reverse flow of the washing water is actively generated through the right space portion, and the washing power is greatly improved.

1 is a cut-away view for explaining the structure of a general washing machine,
2 is a partially cutaway perspective view for explaining the structure of a washing machine of the washing machine of the present invention,
3 is a cross-sectional view showing the outer cylinder of the washing machine of the present invention and the washing tub,
4 is a partially cutaway perspective view showing another structure of the washing plate constituted in the washing tub of the washing machine of the present invention.

Hereinafter, the technical structure and operation of the washing tub 140 of the washing machine provided with the washing plate of the present invention will be described in detail with reference to FIG. 2 to FIG.

 2, the washing tub 140 of the washing machine of the present invention is formed on the inner wall of the washing tub 140 such that the washing tub 150 protrudes in a streamlined manner with a predetermined width along the longitudinal direction of the washing tub 140. Each washing plate 150 is formed with a diaphragm 155 for forming left and right space portions 150a and 150b between the inner surface of the washing plate and the inner surface of the washing tub. A plurality of washing holes 141 communicating with the left space 150a or the right space 150b are formed on the slopes of the washing plate divided on both sides with respect to the diaphragm 155.

The washing holes 141 are arranged in the horizontal direction of the left and right slopes so as to form three sets of the washing holes 141 at regular intervals along the longitudinal direction of the washing tub. However, the washing holes 141 are not limited to this structure, The structure is sufficient. The size of the washing holes 141 may be different from each other.

In the structure of Fig. 2, the upper end of the washing plate is shown as being opened for convenience of explanation, but it may be configured to have a closed structure, or may be configured to extend only to the middle of the washing tub.

As shown in FIG. 3, when the wash water mixed with the laundry rotates in the clockwise direction, a part of the wash water flows into the space 150a of each wash plate through the wash hole 141, So that the friction with the laundry is increased in this process, thereby improving the cleaning ability.

On the other hand, when washing water mixed with the laundry is rotated in the counterclockwise direction, a part of the washing water enters the space part 150b of each washing plate through the washing hole 141 and flows back through the washing hole 141 . The water in the outer tub 10 is discharged through the drain pipe (not shown) to the outside of the drum 10 through the drain pipe 41 As shown in FIG.

The reason why the washing plate 150 is formed in a streamlined shape is to induce the laundry to be damaged or tangled when the washing plate comes into contact with the washing plate due to the contact between the washing plate and the washing plate due to left and right rotation of the pulsator during washing.

As shown in FIG. 3, the washing plates 150 may be formed at equal intervals along the inner circumferential surface of the washing tub 140 as shown in FIG. 3. The washing plates 150 may have a wavy shape, .

As described above, the diaphragm 145 protruding in a streamlined shape on the inner surface of the washing tub and the washing plate having the washing holes 141 are formed at regular intervals, so that the washing performance is improved and the washing time is improved as compared with the conventional washing tub.

The washing tub of the washing machine provided with the washing plate of the present invention is not limited to the above-described illustrated structure, and various modifications are possible without departing from the purpose of the present invention and claims.
