The present invention relates to a washing water injector of a dishwasher, and more particularly, to change the washing water spray angle of the spray arm installed in the dishwasher to variously spray the washing water.

In the conventional dishwasher, as shown in FIGS. 1 and 2, the washing water passing through the water supply passage 11 installed in the frame 1a of the spray arm mechanism part is provided in the frame 1a and rotates the wing portion 12. As the first gear 14 moves, the second gear 15 interlocked with the upper part rotates as the first gear 14 moves and rotates, and is connected between the spray arm 8a and the second gear 15. The connecting rod 7a rotates the spray arm 8a at a predetermined angle to spray the washing water.

However, such a conventional washing water dispersing device is too complicated in structure, and because the power must be transmitted to the first and second gears 14 and 15, not only noise is severely generated, but also the first and second gears into the washing chamber. (14) and (15) is exposed, so that the dirt easily caught, the part that rotates the spray arm (8a) is installed only on one side, so that the precise movement is not possible, such as to lower the cleaning efficiency and had problems.

The present invention is to solve the above-mentioned problems, the present invention is to change the washing water spray angle of the spray arm installed in the dishwasher in a simple structure in various ways to not only improve the washing efficiency by spraying a wide range of washing water The object of the present invention is to provide a washing water spraying device for dishwashing, which can greatly reduce noise generated.

In order to achieve the above object, the present invention is fixed to the shaft of the water supply guide connected to the frame is a first gear that is integrally rotated, the second gear is installed in the frame and connected to the first gear, and the second A connecting rod is formed eccentrically to the gear to change the rotational movement of the second gear into a linear movement, and a long hole is formed in which the connecting rod is inserted and connected by the rotational movement of the second gear. It is a washing water injector of the dishwasher consisting of a connecting member for changing the spraying angle of the washing water by activating the spray arm.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 3 to 5.

Figure 3 is an exploded perspective view showing the present invention, Figure 4 is a longitudinal cross-sectional view showing a combined state of Figure 3, Figure 5 is a cross-sectional view and a longitudinal cross-sectional view showing the operating state of the present invention, the frame of the spray arm mechanism portion in the dishwasher (1) The shaft 3 is installed in the center of the water supply guide 2 connected to the lower end, and the first gear 4 which is integrally rotated with the shaft 3 is inserted in the upper part of the shaft 3 so that the frame ( 2, a second gear 6, which is connected to both sides of the first gear 4 and rotates in the frame 1, is fixed as the nut 5 through the first gear 180. A phase difference of ° is formed and installed.

In addition, connecting rods 7 are installed on the plurality of second gears 6 in the frame 1 so as to be eccentric to convert rotational movements of the second gears 6 into linear movements. A connecting member 10 having a long hole 9 is formed at one end of the installed spray arm 8 so that one end of the connecting rod 7 is freely inserted into the long hole 9 so that the second gear 6 One end of the eccentric connecting rod 7 is connected to the long hole 9 of the connecting member 10 in accordance with the linear movement of the connecting rod 7 by the rotational movement of the spray rod 8. 8) is configured to vibrate to spray the washing water.

In the present invention configured as described above, as shown in FIGS. 3 to 5, the washing water supplied to the water supply guide 2 connected to the lower part of the frame 1 of the spray arm mechanism part in the dishwasher is sprayed through the spray arm 8. As the spray arm (8) is rotated.

At this time, both sides of the first gear 4 which is fixed as a nut 5 through the frame 1 on the shaft 3 in the center of the water supply guide 2 by water pressure of the washing water and rotates integrally with the shaft 3. A plurality of second gears 6, which are connected to the first gear 4 and provided with a phase difference of 180 degrees around the first gear 4, are rotated.

At the same time, the connecting rod 7 converts the rotational motion of the second gear 6 into a linear motion so as to be eccentrically on the plurality of second gears 6, and on the upper end of the spray arm 8 installed in the frame 1. One end of the connecting rod 7 eccentrically connected to the long hole 9 of the connecting member 10 and the second gear in a state where one end of the connecting rod 7 is freely inserted into the long hole 9 formed in the connecting member 10. As shown in FIG. 5, as the spray arm 8 is rotated from side to side as shown in FIG. 5, the spray arm 8 vibrates to vary the washing water spraying angle to vary the washing water. It can be sprayed.

On the other hand, the number of vibrations of the spray arm 8 and the number of teeth of the circumferential surface of the first gear 4 and the second gear 6 connected to the first gear 4 are arbitrarily adjusted and used as necessary. The rotation speed can be adjusted.

As described above, the present invention is connected to the first gear (4) which is fixed to the upper portion of the shaft (3) of the water supply guide (2) connected to the lower end of the frame (1) of the spray arm mechanism unit in the dishwasher and integrally rotated The second gear 6 is installed, the upper portion of the second gear 6, the connecting rod 7 for converting the rotational movement of the second gear 6 into a linear motion is installed eccentrically The spray arm 8 in the frame 1 is inserted into the long hole 9 of the connecting member 10 at the upper end, and the spray arm 8 is rotated by the rotational movement of the second gear 6. It is a very useful invention that improves the efficiency and reliability of the product because the spray arm (8) without the power source of the vibration can be improved by varying the washing water injection angle is changed in various ways, as well as to reduce the noise as a simple structure.
