Description

Dispenser of dishwasher {APPARATUS FOR SPRAYING WATER}

The present invention relates to an injector for a dishwasher, and more particularly, to an injector for a dishwasher in which an injection range of the washing water sprayed into the washing chamber can be extended.

The dishwasher is a device for automatically washing dishes, and washes foreign substances on the dishes by the spray water pressure of the washing water sprayed through the spray nozzle, and when the washing is completed, the dishwashing water is dried.

Such dishwashers are usually added to the washing water and sprayed on the dishes, thereby washing the dishes.

1 is a view illustrating a general dish washer.

Referring to FIG. 1, a door 11 is mounted on a front surface of the main body 10, a washing chamber 12 is formed behind the door 11, and the washing water is sprayed on an upper portion of the washing chamber 12. Injector 13 is formed.

A discharge pipe 14 for discharging the washing water is formed at the bottom of the washing chamber 12, and a bottom plate 15 is formed at the upper end of the discharge pipe 14 to guide the washing water to the discharge pipe 14.

The bottom plate 15 is provided with a storage rack 16 for storing a plurality of dishes, the storage rack 16 has a basket shape for storing the dishes, but a net having a large hole to facilitate the introduction and discharge of the washing water. It has a shape.

On the other hand, washing water is injected into the injector 13 through the nozzle to strongly hit the dishes stored in the storage rack 16 to wash the dishes.

In general, the dishwasher cannot spray washing water evenly in the main body because the nozzle is formed in the fixed sprayer, and in particular, the dishwashing machine does not spray the washing water sufficiently in the dishware placed at the corners. Therefore, there is a need for improvement.

The present invention has been made by the necessity as described above, and an object of the present invention is to provide an injector for a dishwasher, in which an area to which the nozzle is sprayed can be expanded and the washing water can be evenly sprayed.

Dispensing apparatus of the dishwasher according to the present invention comprises: an operating unit including a moving unit; A supply pipe which moves in association with the moving unit and supplies washing water; And a nozzle in communication with the supply pipe, the nozzle including a nozzle for spraying the washing water.

In one embodiment, it further comprises a fixing part which is formed eccentrically in the longitudinal direction of the supply pipe to form a moving shaft of the supply pipe.

In one embodiment, the fixing portion is formed with a funnel-shaped through-hole widening from the upper end to the lower end.

In one embodiment, a rubber seal is provided on the circumferential surface of the through hole.

In one embodiment, the operation unit further includes a hydraulic cylinder for restraining the operation of the moving unit.

In one embodiment, the feed duct is rigid.

Unlike the conventional invention, the dispensing apparatus of the dish washing machine according to the present invention can enlarge the area in which the nozzle is sprayed and thus the washing water can be evenly sprayed, thereby washing the dishes placed in the corner area, thereby improving the washing efficiency.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the injector of the dishwasher according to the present invention. In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or convention of a user or an operator. Therefore, definitions of these terms should be made based on the contents throughout the specification.

2 and 3 are front views schematically showing the injector of the dishwasher according to an embodiment of the present invention, Figure 4 is a cross-sectional view showing a fixing portion of the injector of the dishwasher according to an embodiment of the present invention. 5 is a bottom view illustrating a spray unit of the injector of the dishwasher according to the embodiment of the present invention.

2 to 5, the injector 100 of the dishwasher includes an operation unit 110, a supply pipe 120, and an injection unit 140.

The operation unit 110 is provided above the washing chamber (not shown), and includes a moving unit 111 and a hydraulic cylinder 115. The hydraulic cylinder 115 is connected to one end of the moving part 111 to constrain the operation of the moving part 111. When the arm of the hydraulic cylinder 115 is moved left and right, the moving part 111 linked to the hydraulic cylinder 115 is reciprocated left and right.

The operation unit 110 is provided inside the washing chamber or separated from the washing chamber and is provided between the washing chamber and the inside of the main body (not shown) of the dishwasher. The operation unit 110 is provided with a moving unit 111 and the hydraulic cylinder 115, the position is not limited to the configuration to induce movement. ..

The moving part 111 is provided with a supply pipe 120 for supplying washing water. The supply pipe 120 communicates with the water pipe outside the dishwasher via the moving unit 111, and receives the washing water from the water pipe and supplies the washing water to the washing chamber. The supply pipe 120 is formed of a material constituting rigidity, and when the upper end of the supply pipe 120 is moved in accordance with the movement of the moving unit 111, the supply pipe 120 is also linked to the lower end of the supply pipe 120. In addition, the supply pipe 120 is made of a rubber material to prevent the supply pipe 120 is corroded by the wash water.

Fixing unit 130 is fixed to the wall surface of the washing chamber, it is provided eccentrically on the upper side in the longitudinal direction of the supply pipe (120).

The fixing part 130 is formed with a funnel-shaped through hole 131 widening from the upper end to the lower end, and the supply pipe 120 is inserted into the through hole 131. The through hole 131 is formed in a funnel shape, when the supply pipe 131 is moved left and right, the movement is not hindered by the fixing part 130. In addition, a rubber seal 125 is provided on the circumferential surface of the through hole 131 to smooth the contact surface between the through hole 131 and the supply pipe 120 so that the supply pipe 120 generates friction by the fixing part 130. To improve durability.

And when the supply pipe 120 is moved in conjunction with the moving unit 111, the fixing unit 130 forms a moving shaft of the supply pipe 120. When the moving part 111 moves, the horizontal radius of movement of the supply pipe 120 is moved in proportion to the upper end length of the fixing part 130 and the lower end length of the fixing part 130 with the fixing part 130 as the axis. .

The operation unit 110 for moving the upper end of the supply pipe 120 by moving the upper end of the supply pipe 120 by the fixing unit 130 is installed eccentrically with only driving energy for moving the moving radius of the upper end of the supply pipe 120 Since driving radius of the lower end of the supply pipe 120 is formed, driving energy can be reduced.

The injection unit 140 communicates with the supply pipe 120 and includes a nozzle 141 for spraying washing water. In the present embodiment, the injection unit 140 is a hexahedron in which a space is formed to store the washing water, and a nozzle 141 is formed at a lower surface thereof. The injection unit 140 moves in conjunction with the supply pipe 120 and moves along the left and right sides of the supply pipe 120. The washing water sprayed from the nozzle 141 by the inertial action is inclined and discharged.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. Will understand. Therefore, the true technical protection scope of the present invention will be defined by the claims below.
