Abstract

The washer nozzle is constructed in a multistep for allowing its rotation and up and down motion in accordance with the variation of water pressure. The water jet rotation nozzle is designed in 2-5 steps. There are three step nozzles; the base nozzle is founded in center of water bath, the second nozzle is protruded from third nozzle and supported by the third nozzle, and the first nozzle is protruded and supported by the second nozzle. The height of each nozzle is regulated spontaneously by the spring which is actuated by the water pressure.

[Field of Invention]

The present invention relates to a water spray nozzle used in the dishwasher.

More specifically, the present invention relates to a dish washing machine rotary multi-layer nozzle in which the nozzle is configured in multiple stages and rotates in accordance with the change in water pressure to spray water.

[Background of invention]

In the conventional dishwasher, the nozzle was fixed at a fixed position. That is, in most cases, in the conventional dishwasher, the nozzle is built in the center of the inside of the dishwasher. Therefore, in the conventional dishwasher, the water is sprayed only to a certain portion from the lower center where the nozzle position is fixed to the upper part, so that only a portion of the lower part of the washing table is sprayed and the water cannot reach the specific washing unit and the dishwasher. There was a problem in which the rice paste or debris was dried and dried.

As shown in FIG. 1, in the conventional dishwasher, the nozzle 1 was fixed to the lower center of the dishwasher. Therefore, it was difficult to spray water sufficiently in the whole part of the dishwasher with the water spray 3 into the dishwasher through the injection hole 2 during the rotation of the nozzle 1 during operation. That is, due to the rotation of the fixed nozzle 1, the water spray 3 has a slight angle by performing various movements such as rotation and torsion, not only a vertical rise, but water spray only on the lower portion of the washing table 4. Only (3) reached well, there was a problem that the water spray (3) does not reach well in the upper part of the washing table (4) and elsewhere in the dishwasher.

[Purpose of invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a dishwasher rotating multi-layered nozzle which can prevent water from being sprinkled on the dishwasher evenly without being sprinkled with rice paste or debris throughout the dishwasher.

[Summary of invention]

The dishwasher rotary multi-layer nozzle of the present invention has a new structure in the center of a conventional water spray rotary nozzle installed in the dishwasher, and installs a separate nozzle in a multi-layered structure similar to an antenna, thereby rotating the multilayered layer as the water pressure increases from the lower part of the nozzle. As the nozzle rotates, the 1st stage nozzle, which is the uppermost layer, rises stepwise to the upper part of the washing station through the gap in the lower center of the washing table, and evenly sprays all parts of the washing table and the tableware through the plurality of spray holes formed in the nozzle of the upper layer. Characterized by a structure made to be.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[Description of Specific Example of the Invention]

The configuration of the present invention is as follows.

As shown in FIG. 2, the dish washing machine rotating multi-layer nozzle includes a washing stage 4 inserted into the dish washing machine, a three-stage nozzle 8 installed over the rotating nozzle 10 and the reservoir 14 of the dish washing machine. ), The second stage nozzle (7) which is supported inside the three-stage nozzle and the top of which is exposed to the outside of the third stage nozzle and the second stage nozzle is supported by the inside of the second stage of nozzle and the upper stage is exposed to the outside of the second stage nozzle. Rotating multi-layer nozzle (5) of the multi-stage rotary nozzle consisting of one-stage nozzle (6), the three-stage nozzle (8) and the circular projections (13, 15) integrally installed on the lower stage of the two-stage nozzle (7) A water supply device for supplying water to the spring (17) installed between the single nozzle (6) and the second stage nozzle (7), the plurality of injection holes (9) provided in the first stage nozzle (6), and the reservoir (14). (11) and a side hole (12) provided on the side of the water supply device (11). The three layers of the rotary multi-layer nozzle (5) is for convenience of explanation, and the three layers of the rotary multi-layer nozzle (5) are usually most suitable, but according to the size or use of the dishwasher, The layer of the rotary multilayer nozzle 5 can be appropriately changed to about 5 steps. In addition, the above water pump is not shown for the sake of brevity.

The circular protrusions 13 and 15 integrally installed at the lower part of the three-stage nozzle 8 and the two-stage nozzle 7 are three-stage nozzles of two-stage nozzles and one-stage nozzles slidably mounted therein. 8) and two-stage nozzle (7) to suppress the deviation from the inside and at the same time acts as a support point of the spring inserted between the nozzle to act as a means to enable the smooth movement of the multi-layer nozzle up and down. .

Referring to the operation and effect of the present invention.

In the dishwasher rotary multi-layer nozzle of the present invention illustrated in FIG. 2 and FIG. 3, the rotary multi-layer nozzle 5 (6 + 7 + 8) is folded in the state of FIG. The first stage nozzle 6 is extended to the washing table 4 to spray water through the injection hole (9).

Referring to FIG. 4, the dish washing machine rotary multi-layer nozzle of the present invention is partially supplied with water supplied through the water supply device 11 to the side hole 12 to gradually fill the rotary nozzle 10, and part of the upper hole. It is ejected to (13) and prepares the role of pushing up the rotary multilayer nozzle (5; 6 + 7 + 8). At this time, when the water in the reservoir rises to the third stage nozzle (8), the lightest first stage nozzle (6) rises rapidly by the water pressure, and the second stage nozzle (7) is at a medium speed, and the third stage nozzle (8) is the most. Ascend slowly. At this time, the entire rotary multilayer nozzle 5 rises while rotating in accordance with the oil in the rotary nozzle 10. The one-stage nozzle 6 which rotates in this way rises up to the upper part of the washing table 4 through the gap in the lower center of the washing table 4 while spouting water through the plurality of injection holes 9. Water is sprayed to every corner of the dishwasher.

After the dishwasher is finished, the water in the water tank 14 is drained, and the springs 16 and 17 are respectively disposed in the internal gaps of the three-stage nozzle 8, the two-stage nozzle 7, and the first-stage nozzle 6. In this case, when the water supply is completed, the rotary multi-layer nozzle 5 is lowered by the restoring force of each spring, but at this time, the rotary multi-layer nozzle 5 is lowered to a certain degree and then the spring 16, It is physically supported by the tension and circular protrusions 13 and 15 and the water supply device 11 of 17) and no longer descends.

As described above, the present invention improves the problem that the conventional dishwasher can properly inject water only into the lower side of the washing table 4, and thus the first stage nozzle 6 for spraying water has a lower portion of the washing table 4. It is an excellent invention to double the washing effect of the dishwasher by spraying the water evenly through the plurality of spray holes (9) throughout the washing table 4 while rotating and rising simultaneously to the top of the washing table (4).

Although the present invention has been described in detail only with respect to the above-described embodiments, it will be apparent to those skilled in the art that the present invention may be changed or modified within the spirit and scope of the present invention, and such changes or modifications are attached to the appended claims. Should be limited only by
