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

FIG. 5 is a view showing an example of a guide structure of a rotating body motion according to the present invention, in which the partition walls 11 are formed with three nozzles or flow paths 21, 22, and 23 leading to the nozzles.

The flow paths 21, 22, 23 are covered by a cover 24 having the same shape, and selectively communicate with the supply flow path 25 which is continued from the pump (not shown).

For selective communication between the flow passages 21, 22, and 23 and the supply flow passage 25, the rotating body 4 is provided on the supply flow passage 25, and the vertical movement of the rotating body 4 is supplied to the supply flow passage 25. It is guided by, the rotational movement of the rotating body 4 is guided by the guide 50 formed in the supply passage 25 and the cover 24. That is, the guide 50 and the guide 60 correspond to the zigzag opening 131 shown in FIG. It goes without saying that the shapes and structures of the flow paths 21, 22, 23 and the cover 24 may be changed depending on the number of nozzles or flow paths, the position of the nozzles or flow paths, and the like.

The rotating body 4 is arranged along the circumference of the disk 4b and the disk 4b in which the opening 4a is formed so that water sent to the supply flow path 25 by the pump can move to one of the flow paths 21, 22, and 23. It is formed and formed along the periphery of the upper projection (4c) and the disk (4b) to cooperate with the guide 60, and consists of a lower projection (4d) to cooperate with the guide (50). The upper protrusion 4c has three vertices 4e, and the vertices 4e are formed at intervals of 120 degrees. There is no particular limitation on the length of the two sides 4f and 4g forming the vertex 4e, but it is preferable to lengthen the length of the side 4f guided by the guide 60 so as to be stably guided. The lower protrusion 4d likewise has three vertices 4h. The positional relationship between the vertex 4e of the upper protrusion 4c and the vertex 4h of the lower protrusion 4d will be described later.

The cover 24 is a cylindrical body 24d which connects the branches 24a, 24b and 24c covering each of the flow paths 21, 22 and 23 and the branches 24a, 24b and 24c and is fitted into the supply flow path 25. It includes. The lower part of the cylindrical body 24d is formed with a guide 60 interlocking with the upper protrusion 4c, and therein, three walls which separate the flow paths 21, 22, and 23 and have the same shape as the opening 4a. 24e is formed, and the opening part 24f which communicates with each of the flow paths 21,22,23 is formed in the upper part.

On the other hand, the guide 50 which cooperates with the lower protrusion 4d is formed in the surface which forms the supply flow path 25. As shown in FIG.

6 to 9 are diagrams illustrating the motion of the rotating body according to the present invention. FIG. 6 shows a process in which the rotating body 4 is lifted by water supplied from a pump, and FIG. 7 shows the rotating body 4. ) Is continued, and the upper protrusion 4c of the rotating body 4 is guided by the guide 60, and it shows the process of rotating when it raises. In these processes, water moves through the openings 4a into the flow paths 21, 22, and 23, so that the flow loss is reduced, and then water can be supplied quickly to the selected flow path. On the other hand, since the pressure received by the disk 4b is reduced, the rotating body 4 can be smoothly guided along the guide 60. In addition, the rotating body 4 is an asymmetrical structure having an opening 4a, but is guided along the supply flow path 25, so that the rotating body 4 can be guided without tilting, and does not require a separate member to eliminate the tilting. 8 shows a state where the disk 4b is fully raised and fully engaged with the guide 60, wherein the openings 4a are blocked by the wall 24e and communicate with the openings 4a. 23) Only one of them will be supplied with water. FIG. 9 illustrates a process in which the lower protrusion 4d is guided by the guide 50 while the pump is stopped and the rotor 4 is lowered.

There is no particular limitation on the positional relationship between the vertex 4e of the upper protrusion 4c and the vertex 4h of the lower protrusion 4d. However, in relation to the guide 50 and the guide 60, the upper protrusion 4c should be guided by the guide 60 when the rotor 4 is raised, so that it is lower than the vertex 60a of the guide 60 being guided. It is preferable to be located at the right side, and the lower protrusion 4d should be guided by the guide 50 at the time of the lowering of the rotor 4, so it is preferable to be located at the right side than the vertex 50a of the guide 50 to be guided. . Therefore, if the rotating body 4 can be guided by the guide 60 when the rotating body 4 is raised, and the rotating body 4 can be guided by the guide 50 when the rotating body 4 is lowered, The projections 4c, the lower projections 4d, the guides 50, and the guides 60 do not have any particular limitations on their vertex positions and the shapes of the sides constituting the vertices.
