The present invention relates to a dishwasher, and more particularly, the spray pipes connected to both sides of the washing water supply pipes mounted in the front and rear directions of the dishwasher, respectively, are inclined toward the rack containing the dish. And nozzles mounted at the front and rear of the nozzles coupled to the injection pipe are rotated to the rack together with the injection pipe so that most of the washing water is concentrated on the dishes so as to maximize the cleaning efficiency. will be.

In general, the dishwasher is a dish for washing the dishes more hygienically and efficiently. The washing water contained in the lower tank of the dishwasher is mainly transferred to the supply pipes installed at the top and bottom of the dishwasher by a pump. Thus, the washing water is sprayed with high pressure through the nozzles of the injection pipe continuously coupled to the supply pipe to clean the dishes placed on the rack.

The injection pipe is horizontal to both sides of the supply pipe, the nozzles are perpendicular to the injection pipe to inject the washing water, and the washing water sprayed from the nozzle is sprayed while spreading to make the heat to correspond to the width of the rack eventually Closures occurred such that a significant amount of wash water sprayed from the mounted nozzles splashed out of the rack.

Therefore, since the washing water sprayed from the nozzle could not be concentrated in the rack, it could not increase the efficiency of washing, and there was a problem of generating considerable noise while the scattering washing water collided with the inner wall of the case.

In addition, since the washing water was scattered until the subsequent rinsing process after washing, efficient rinsing could not be performed, and thus, a sufficient distance between the washing process and the rinsing process had to be secured. Occurred.

In addition, since the combination of the injection pipe and the supply pipe is fixed by welding the cylindrical injection pipes on both sides of the supply pipe made of stainless steel square pipes, the discolored welding part should be erased with a chemical called a stain cleaner. It was very difficult and cumbersome and had a bad effect on the environment, and because the injection pipe was completely welded to the supply pipe, it was very inconvenient to clean the residues remaining inside the injection pipe and the supply pipe.

The present invention has been made in view of the above-described problems, and its object is that the injection pipes connected to both sides of the washing water supply pipes mounted on the upper and lower portions of the dishwasher are inclined toward the rack containing the dish, The nozzles mounted on the front and rear of the nozzles attached to the pipes are rotated to the rack together with the injection pipes so that most of the washing water is concentrated on the dishes, thereby providing a dishwasher that can maximize the efficiency of cleaning. .

The combined nozzles 25 are mounted in rows and columns to correspond to the width of the rack 50 so that the washing machine 1 sprays the washing water toward the upper and lower portions of the dish 51 contained in the rack 50. The supply pipes 23 are formed of square pipes, and coupling holes 23a are continuously drilled on both sides thereof, and coupling pipes 42 and 42 'are formed on both sides of the support plate 41 to be inclined. A coupling pipe 42 'formed inside is inserted into the coupling hole 23a of the supply pipe 23 to penetrate the support plate 41. The bracket 40 is fixed to the supply pipe 23 by the screw 43 to be connected, and the injection pipe 24 is inserted into and fixed to the coupling pipe 42 formed on the outside of the bracket 40 to the upper supply pipe 23. The combined both injection pipes 24 are inclined downward, and both injection pipes 24 coupled to the lower supply pipe 23 are inclined upwardly so that the nozzles 25 coupled to the injection pipe 24 are rack 50. It is installed so as to face the, and the injection pipe 24 is fixed by the screw 43 is fastened to the injection pipe 24 through the long hole (42a) drilled in the coupling pipe 42 formed on the outside of the bracket 40 The injection pipe 24 is rotatably fixed to the bracket 40 within the range of the long hole 42a, and the injection pipes 24 mounted at the front and rear of the upper and lower supply pipes 23 are perpendicular to each other. It can be achieved by the dishwasher, characterized in that it is fixed in a state rotated to face the rack (50).

Hereinafter, described in detail by the accompanying drawings a preferred embodiment for achieving the above object is as follows.

1 to 8, the washing water tank 20 is mounted inside the case 10 of the dishwasher 1, and the transfer pipe 22 is vertically located inside the case 10. It is mounted, and the wash water stored in the wash water tank 20 can be vertically transferred through the transfer pipe 22 by the pump 21.

The supply pipes 23 are respectively mounted in the front and rear directions in the upper and lower portions of the transfer pipe 22, and the injection pipes 24 are continuously coupled to both sides of the supply pipes 23 in the horizontal direction.

The nozzles 25 are coupled to the injection pipes 24, and the nozzles 25 coupled to the supply pipe 23 are mounted in a row in a horizontal direction so as to correspond to the width of the rack 50. The washing water is sprayed toward the upper and lower portions of the dishes 51 contained in the rack 50 through the 25 to wash the dishes 51.

The rack 50 is placed on the rail 11 across the center of the case 10 to be transported. The rinse water tank 30 is mounted on the right side of the wash water tank 20, and the rinsing water stored in the rinse water tank 30 is transferred by the pump 31 to the rinse nozzle mounted on the right side of the case 10. It can be sprayed through the (32).

Of course, the dishwasher 1 having the above-described configuration is a known art. However, the most important feature in the present invention is that the injection pipe 24 is coupled to make an inclination in the supply pipe 23 by a separate bracket 40 to maximize the efficiency of the cleaning operation.

That is, the supply pipes 23 are formed of square pipes, and coupling holes 23a are continuously drilled at both sides of the supply pipe 23.

The bracket 40 coupled to the coupling holes 23a has a configuration in which coupling pipes 42 and 42 'are inclined on both sides of the support plate 41, and the inclination angle α is shown in FIG. It is desirable to achieve about 5 ° horizontally.

When the coupling pipe 42 'formed inside the bracket 40 is inserted into the coupling hole 23a drilled in the supply pipe 23, the support plate 41 is in close contact with both sides of the supply pipe 23, and the support plate 41 The brackets 40 are continuously coupled to both sides of the supply pipe 23 by the screws 43 fastened through the fixing holes.
