Next, the nozzle device 8 will be explained in detail.

Reference numeral 12 denotes a cylindrical body, which has a front opening reduced to form a step 13 and a flange 14 formed around the rear opening. Reference numeral 15 denotes a cylindrical cover that is watertightly attached to the flange 14 of the cylinder body 12, and is partitioned into a front space with an open front and a rear space with an open rear by a shielding wall 16 provided approximately at the center; The front space is communicated with the inside of the cylinder body 12. The rear space of the cover 15 is divided into an upper space and a lower space by a partition wall 17, and a first water inlet 18 connected to the water outlet OA of the switching valve 9 by a connecting pipe A is watertightly provided in the upper space. A second water inlet 19, which is connected to the water outlet OB of the switching valve 9 through a connecting pipe B, is watertightly installed in the lower space. A first through hole 20 that communicates between the front space and the upper space and a second through hole 21 that communicates between the front space and the lower space are bored in the shield wall 16, and the first through hole 20 and the second through hole 21 that communicate between the front space and the lower space are formed on the front space side of the shield wall 16. An elastic plate 22 serving as a blocking means that covers the second through holes 20 and 21 is bent by the pressure of the washing water flowing in from the first and second water inlets 18 and 19, and the first and second through holes 20 and 21 are bent. It is fixed to open.

A nozzle 23 is housed in the cylinder body 12 with a small gap, and is projected to a predetermined position from the opening of the cylinder body 12 by the pressure of the cleaning water flowing in through the first and second water inlets 18 and 19. A receiving portion 24 is formed on the rear outer periphery thereof, and an abutting portion 25 is formed at a predetermined distance in front of this receiving portion 24. An annular gasket 26 is disposed on the abutting portion 25, and when the nozzle 23 protrudes to a predetermined position, it abuts against the stepped portion 13 of the cylindrical body 12 to prevent the nozzle 23 from protruding. A spring 27 is interposed between the receiving portion 24 of the nozzle 23 and the stepped portion 13 of the cylinder body 12, and constantly biases the nozzle 23 in the direction of housing it in the cylinder body 12. 28, 29
are first and second water passages of different lengths formed in the axial direction within the nozzle 23, with first and second ejection holes 30, 31 formed in front of each;
The rear end is open.

32 has a rear end that passes through the shielding wall 16 and communicates with the upper space, and a front end that communicates with the first water passage 2 of the nozzle 23.
The first water pipe 33 is inserted to the front part of the second water passage 29 of the nozzle 23, and its rear end passes through the shielding wall 16 and communicates with the lower space, and its front end is inserted to the front part of the second water passage 29 of the nozzle 23. A second water pipe 34 is connected to the first and second water pipes 28, 29 and the first and second water pipes 3.
It is a gasket that seals watertightly between 2 and 33.

Next, the operation of the cleaning water discharge device 4 will be explained.

First, the water inlet I of the switching valve 9 is communicated with the water outlet OA, and when the pump 7 injects the wash water in the tank 6 into the upper space through the first water inlet 18, a part of the wash water flows into the elastic plate 22. is deflected and flows into the front space through the first through hole 20, pushes out the nozzle 23 to protrude, and is discharged outward from the opening of the cylinder body 12 through the gap between the cylinder body 12 and the nozzle 23. At this time, the washing water washes the outer wall of the nozzle 23 and the inner wall of the cylinder body 12, which is very hygienic. On the other hand, a part of the washing water injected into the upper space passes through the first water pipe 32 and the first water passage 28,
It is discharged outward from the first jet hole 30. When the nozzle 23 does not protrude to a predetermined position (see FIG. 2), a portion of the cleaning water is discharged from the opening through the gap between the cylinder body 12 and the nozzle 23, as described above. The pressure of the washing water ejected from the first ejection hole 30 is low, and the washing water does not come into contact with anything other than clothes or the parts to be cleaned. Further, the cleaning water that has entered the cylinder body 12 flows back into the lower space through the second through hole 21 and tries to be discharged from the second jet hole 31 through the second water pipe 33 and the second water passage 29. However, since the elastic plate 22 covers the second through hole 21, the water does not flow back into the lower space.

When the nozzle 23 protrudes to a predetermined position, the gasket 26 and the stepped portion 13 come into contact with each other, and all of the injected cleaning water is discharged from the first jet hole 30 via the first water pipe 32 and the first water passage 28. Wash your private parts.

Further, when the water inlet I and the water outlet OB of the switching valve 9 are communicated, the cleaning water flows into the lower space through the second water inlet 19, and the water inlet I and the water outlet OB of the switching valve 9 are communicated. As in the case, the nozzle 23 is made to protrude to a predetermined position, and cleaning water is ejected from the second ejection hole 31.

In addition, in this embodiment, the first and second water inlets 18, 19
Although the cover 15 is formed separately, it may be formed integrally as shown in FIG.

(g) Effects of the invention Since the washing water discharge device of the invention is constructed as described above, when water is injected into one of the water inlets by the water injection means, the nozzle is moved to a predetermined position by the pressure of the washing water flowing into the cylinder body. The cleaning water projected to the position and injected into the cover through one of the water inlets is ejected from one of the ejection holes of the nozzle through one of the water pipes and one of the water passages that communicate with the cover. At this time, the cleaning water that entered the cylinder body through the cover is prevented from flowing into the other water pipe by the blocking means provided on the cover, and the jetting of cleaning water from the other nozzle nozzle is prohibited. can do. Therefore, since one nozzle can discharge cleaning water to two positions, the configuration is very simple, the installation space is small, and the installation work is easy.

Further, as the number of ejection holes is increased by one, only one connecting pipe connected to the water inlet needs to be added, and the number of connecting points of the connecting pipes is not increased unnecessarily. Furthermore, since a predetermined amount of washing water is ejected from the spout hole after the nozzle protrudes to a predetermined position, it is possible to minimize the occurrence of a situation in which the washing water is ejected to areas other than the area to be cleaned.
