FIG. 4 is a perspective view of the spray nozzle shown in FIG. 3, FIG. 5 is a view showing the spray hole shown in FIG. 4, and FIG. 6 is a form of washing water sprayed into the inner tank by the spray nozzle according to the embodiment of the present invention. 7 is a side view for explaining the shape of the washing water sprayed into the inner tank by the injection nozzle in accordance with an embodiment of the present invention, Figure 8 is a partial cut to show the injection form of the washing water Perspective view.

6 and 7, the spray nozzle 50 is disposed to spray the washing water downward to the bottom surface and the sidewall of the inner tank 6.

Referring to FIG. 7, when the spray nozzle 50 is coupled to the top cover 3, the spraying direction of the washing water is any one of the left side wall 6a and the right side wall 6b of the inner tub 6. Rotated at a predetermined angle (W) to be biased by the coupling.

In the present embodiment, since the spray nozzle 50 is disposed on the right side of the inner tank 6, the spray nozzle 50 is rotated to face the left wall 6a of the inner tank 6. do.

4 and 5, the injection part 52 is formed to extend downward from the upper side of the pipe part 51 to be inclined downward, and extends downward from the lower side of the pipe part 51 to the upper surface. It consists of a lower surface part 52b which opposes the part 52a, and the left and right surface parts 52c and 52d which connect between the upper surface part 52a and the lower surface part 52b.

The upper surface portion 52a limits the upward spray angle of the water sprayed through the sprayer 52, and the left and right surface portions 52c and 52d are left and right sides of the water sprayed through the sprayer 52. Directional injection angle can be limited.

The upper surface portion 52a is formed to be inclined downward from the pipe portion 51, and the upper surface portion 52a and the lower surface portion 52b are formed to be expanded in the vertical direction.

Depending on the angle formed by the upper surface portion 52a and the lower surface portion 52b, the highest point of spraying may be different.

The left surface portion 52c is formed to be inclined in the left direction from the pipe portion 51, and the right surface portion 52d is formed to be inclined in the right direction from the pipe portion 51. That is, the left surface portion 52c and the right surface portion 52d may have a shape that opens in the left and right directions.

Depending on the angle formed by the left surface portion 52c and the right surface portion 52d, the injection angle of the water in the right and left directions is changed.

On the other hand, the injection unit 52 is formed so that the flow path cross-sectional area gradually increases in the direction in which the washing water is sprayed.

In addition, the injection part 52 is formed such that the flow path cross-sectional area increases toward the left wall 6a of the inner tub 6, that is, toward the left direction L. FIG. That is, the injection unit 52 has a left and right asymmetrical shape with respect to the center of the pipe unit 51.

The injection part 52 is formed such that the distance between the upper surface part 52a and the lower surface part 52b increases toward the left direction L. As shown in FIG.

In order to open the upper surface portion 52a and the lower surface portion 52b toward the left direction L, both the upper surface portion 52a and the lower surface portion 52b may be formed to be inclined. One of the 52a and the lower surface portion 52b may be inclined.

In the present exemplary embodiment, the upper surface portion 52a of the injection portion 52 is formed to be inclined at a predetermined angle θ with respect to the lower surface portion 52b.

Referring to FIG. 5, the upper surface portion 52a of the injection portion 52 is formed to be inclined at the predetermined angle θ so that the left upper and lower height h2 of the injection hole 54 is the right upper and lower height h1. Is formed larger.

In addition, the upper surface portion 52a, the lower surface portion 52b, the seating surface portion 52c, and the right surface portion 52d each have a flat surface without bending.

Since all of the inner surface of the injection portion 52 is made of a flat surface, washing water can be sprayed straight. If there is curvature on the inner surface of the injection unit 52, water hitting the inner surface may occur, so that the upper surface portion 52a, the lower surface portion 52b, the seat surface portion 52c to prevent this phenomenon. ), The right surface portion 52d is each formed of a flat surface without bending.

Portions of the upper surface portion 52a, the lower surface portion 52b, the left surface portion 52c, and the right surface portion 52d that contact each other may be rounded at a predetermined angle.

Referring to FIG. 6, the washing water sprayed from the spraying unit 52 is inclinedly sprayed downward of the inner tank. Since the spray nozzle 50 is rotated and disposed toward the left wall 6a of the inner tub 6, the washing water sprayed from the spray unit 52 is separated from the left wall 6a of the inner tub 6; It touches the floor together.

At this time, the upper boundary line (P) of the portion where the sprayed washing water and the inner tank 6 contacts is formed in an oblique line from the inner surface of the inner tank 6 to the bottom surface, it is effective to widen the spray area have.

In this embodiment, the spray nozzle 50 is disposed to rotate toward the left wall of the inner tank 6, and the same direction as the direction in which the spray unit 52 rotates the spray nozzle 50 is leftward. Since the flow path cross-sectional area is formed to increase, the inclination of the upper boundary line P of the washing water sprayed from the spraying unit 52 may be increased. In addition, the spray surface (S) of the wash water may be enlarged.

The slope of the upper boundary line P is increased and the spray surface S is increased to increase the spraying range of the washing water sprayed through the spraying unit 52.

In addition, referring to FIG. 7, the height of the highest point at which the washing water sprayed from the spraying unit 52 contacts the left wall 6a of the inner tank 6 may be increased. That is, the distance d from the upper end of the inner tank 6 to the highest injection point is reduced. Therefore, the side injection is sufficiently secured and the wetting of the fabric can be effectively made.

In addition, referring to FIG. 8, when the thickness of the spray surface S of the washing water sprayed from the spray unit 52 is increased, the bottom spray area A which contacts the bottom surface or the fabric of the inner tub 6 is increased. Since it can be increased, wetting of the gun can be made more effectively.

Those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. The scope of the present invention is indicated by the scope of the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and the equivalent concept are included in the scope of the present invention.
