Next, regarding the operation of the nozzle structure of the present invention having the above-described configuration, the nozzle structure is used as a device for injecting washing water into a dish to be washed or the like in a washing system for the dish or the like. An example will be described. FIG. 7 is a partially cutaway view showing, in a partially enlarged manner, an operation state of the nozzle structure shown in FIG. Manifold body 1 of nozzle structure
It is assumed that a pipe (not shown) connected to a cleaning water pump (not shown) of the cleaning system is connected to the connection pipe 30 (see FIG. 1) of the cleaning system. The cleaning water pumped by the cleaning water pump is fed into the internal cavity of the manifold body 10 through the connection pipe 30 through the connection pipe 30. Further, each of the cleaning water holes is attached to each nozzle mounting hole 11 of the manifold body 10. It is introduced into the nozzle tube 22 of the nozzle assembly 20. Then, as shown in FIG. 7, the distal end of the nozzle tube 22 makes a revolving motion as shown by an arrow S due to its own flexibility. The radius of the turning motion changes at random from moment to moment within the range inside the nozzle horn 21. Therefore, the cleaning water is sprayed from the injection port at the tip of the nozzle tube 22 as shown by the symbol J, and the spray direction of such cleaning water is changed every moment within the range limited to the opening range of the nozzle horn 21. Can be For this reason, washing water is sprayed evenly on tableware (not shown) stored in a washing basket placed at a washing station (not shown) arranged below the nozzle structure. This results in a very effective cleaning. In addition, since the spray area of the wash water covered by the 20 nozzle assemblies 20 arranged in a matrix is wide, a large amount of dishes and the like can be washed at a time.

In the nozzle structure using the connection body between the nozzle tube and the mounting screw member as described with reference to FIG. 6, the pivotal movement of the tip of the nozzle tube 22 as described above is caused by the flexibility of the nozzle tube itself. In addition to gender,
It has been found that the effect is also provided by the obstruction exerted by the spiral coil 28 on the flush water flow. This is probably due to the obstructive effect provided by the spiral coil 28 on the water flow flowing through the nozzle tube 22, for example, the flexible nozzle tube is bent as a reaction to the resistance to the water flow, and this bending causes the resistance to the water flow. Is changed, and the curvature of the flexible nozzle tube changes as a reaction to the change in the resistance. In this case, it has been experimentally confirmed that the same behavior is exhibited even when the pressure of the water flow flowing through the nozzle tube 22 is largely changed.

FIG. 8 is a view similar to FIG. 1 showing another embodiment of the nozzle structure according to the present invention. In the embodiment of FIG. 1, a large number of nozzle assemblies 20 are provided in a matrix with the manifold body 10 being widened.
In the embodiment of FIG. 8, the manifold body 10 </ b> A is configured such that the nozzle assemblies 20 are arranged in a line as a unit body that does not spread. In this embodiment, the manifold body 10
Four nozzle mounting holes 11 are formed in a line on one side of A,
Four nozzle assemblies 20 can be attached. The nozzle structure unit of the embodiment in FIG.
By arranging an arbitrary number of these units side by side, a nozzle structure having an arbitrary ejection range can be easily configured.

In the embodiment described above, the manifold body is a flat rectangular parallelepiped. However, the present invention is not limited to such a shape of the manifold body. For example, when the nozzle structure of the present invention is used in a cleaning system, depending on the shape of the cleaning chamber in which the nozzle structure is disposed, the shape of the object to be cleaned, and the like, the shape of the manifold body of the nozzle structure may be reduced. The shape is not a flat rectangular parallelepiped, but a flat cylinder, semi-column, elliptical column, semi-elliptical column,
In some cases, a triangular prism shape or the like is preferable. Therefore, the present invention includes the case where the manifold body has such a shape.

In the above description, the nozzle structure of the present invention is used for spraying cleaning water in a cleaning system. However, the present invention is not limited to this, and the fluid may be used in various other systems. It is effective even when used for jetting.
