As shown in FIG. 3, a flange 20b having a diameter larger than that of the support piece 20a is attached to the tip of the support piece 20a, and the receiving portion 1 corresponding to the flange 20b is provided.
A hole 10d is formed at a portion 0c. This hole 10d
Is formed to have a diameter substantially corresponding to the flange 20b. Therefore, the ejection member 20 is formed by the flange 20b.
It is configured not to be pulled out from the receiving part 10c.

As shown in FIG. 7, the inside of the ejection member 20 is hollow. A bellows-like tilting member 21 is connected near the upper portion of the ejection member 20. The tilting member 21 is configured to be able to expand and contract. The tilting member 21 is set so as to come into contact with the peripheral wall 1c of the toilet 1 when the support 10 is mounted on the toilet 1. A connecting hole 22 is formed between the ejection member 20 and the tilting member 21 as shown in FIG.
The ejection member 20 has a cross section substantially T
A character-shaped partition plate 23 is formed. This partition plate 23 vertically separates the connecting hole 22 and the ejection member 20. As shown in FIG. 7, the connecting hole 22 is formed with an inlet 22a on the upper side and an outlet 22b on the lower side. The ejection member 20 has an ejection port 24 at its lower end.
Is formed.

Reference numeral 25 denotes a helical coil spring.
The spring 25 is mounted on the ejection member 20 and the support 10. That is, as shown in FIG. 3, the coil portion of the spring 25 is inserted into the receiving portion 10 c of the support 10, and both ends are locked by the support portion 10 b and the ejection member 20, respectively. Therefore, the ejection member 20 is always urged toward the tilting member 21 by the spring 25. Therefore, the tilting member 21 is always kept in a reduced state.

Reference numeral 19 denotes a blind plate, which has a thin plate shape (see FIG. 4). The blind plate 19 is for preventing contamination of the ejection member 20 and is set to a size that can cover the ejection member 20 (see FIGS. 2 and 3).
As shown in FIG. 4, the blind plate 19 is disposed on the front side of the ejection member 20. The blind plate 19 is rotatably connected to the shaft 10e of the support 10b.

As shown in FIGS. 3 and 5, a shaft 19a is provided at the upper end of the blindfold plate 19 so as to project toward the base 10a. The shaft 19a and the pin receiving portion 1
6c are engaged. Accordingly, as shown in FIG. 2, the blind plate 19 can rotate in the forward and reverse directions about the axis 10e. The rotation direction of the blind plate 19 is a direction orthogonal to the rotation direction of the ejection member 20 described above.

The other end of the pipe 14, as shown in FIG.
It is connected to a water storage tank (not shown) of a water storage device 27 that stores and pressurizes the washing water. Reference numeral 28 denotes an operation unit for adjusting the flow rate, water pressure, temperature, and the like of the washing water. Note that the sanitary washing device of this example is not provided with a dedicated toilet seat. In addition, various valves (not shown) for adjusting the flow rate and water pressure of the washing water and preventing backflow are provided in the water storage device 27.
Also, an electric pump (not shown) for pressurizing the washing water is provided.

In this embodiment, the installation of the sanitary washing device will be described first. Opened state (state shown in FIG. 10)
The suction cup 11 of the support 10 is attracted to the rear side of the peripheral portion 1a of the toilet 1 with respect to the toilet seat 4 (see FIG. 1). The support 10 in this state has its base 10a opposed to the peripheral edge 1a,
In addition, the support portion 10b projects from the peripheral portion 1a and
b. The support 10 is arranged such that the rear surface of the tilting member 21 is in contact with the peripheral wall 1 c above the water reservoir 1 b of the toilet 1.

When the toilet seat 4 is tilted in the closing direction,
As shown by the two-dot chain line in FIG. 4, the support 10 is sandwiched between the toilet 1 and the toilet seat 4. Therefore, the base 10a of the support 10
Slightly presses the suction cup 11 toward the peripheral edge 1a, so that the support 10 is securely held at a predetermined position.

Next, the use of the sanitary washing device will be described. When the operation unit 28 of the water storage device 27 is operated, the inside of the water storage tank is pressurized, and the cleaning water W is sent toward the ejection member 20 side. The pressurized cleaning water W is supplied to the small diameter portion 12a of the cylinder 12 via the pipe 14. As a result, the cylinder 12 moves from the state shown in FIG. 5 to the state shown in FIG.

That is, due to the pressure of the washing water W, the head 16a of the piston 16 moves to the left against the urging force of the spring 17, as shown in FIG. Then, the shaft 16 b of the piston 16 protrudes from the cylinder 12. Therefore, the cylinder 12 tilts clockwise (as viewed from FIGS. 5 and 6) about the pin portion 13.

Further, the projection of the piston 16 moves the blindfold plate 19 from the state shown in FIG. 5 to the state shown in FIG. That is, since the shaft 19a of the blind plate 19 moves to the left, the blind plate 19 tilts clockwise (as viewed from FIGS. 5 and 6) about the shaft 10e of the support portion 10b.

When the washing water W is supplied, the head 16a of the piston 16 is located on the left side of the pipe 15 of the cylinder 12, as shown in FIG. 6, so that the pipes 14 and 15 of the cylinder 12 communicate with each other. Become. Therefore, the cleaning water W is supplied to the pipe 15. When the cleaning water W is supplied to the ejection member 20, the ejection member 20 moves from the state shown in FIG. 7 to the state shown in FIG. That is, as shown in FIG. 8, the washing water W is guided to the suction port 22 a of the connection hole 22 under the regulation of the partition plate 23.

Then, the cleaning water W is supplied into the tilting member 21, and the water pressure causes the tilting member 21 to expand and expand the tilting member 21. Therefore, the ejection member 20
8, tilts counterclockwise (as viewed from FIGS. 7 and 8) around the support piece 20a against the urging force of the spring 25. By this tilting, the ejection member 20 is pulled out to the front side as shown in FIGS. 8 and 9. Further, the cleaning water W is jetted out of the tilting member 21 through the outlet 22b from the jet port 24 for a predetermined time for a predetermined amount. This spout cleans the area hygienically and comfortably.

When the water is stopped by operating the operation unit 28 of the water storage device 27, the water pressure in the cylinder 12 due to the washing water W decreases. Moving. for that reason,
As shown in FIG. 5, the cleaning water W is supplied to the head 1 of the piston 16.
The supply to the pipe 15 is shut off by 6a. Then, the cylinder 12 tilts counterclockwise around the pin portion 13. Then, the blindfold plate 19 has its axis 19
Since a is pulled back, it tilts clockwise about the axis 10e. As a result, the blind plate 19 is attached to the ejection member 2.
0 can be hidden, and contamination of the ejection member 20 can be prevented.

Similarly, the tilting member 2 by the cleaning water W is used.
Since the water pressure in 1 decreases, the ejection member 20 is tilted clockwise by the urging force of the spring 25. By this tilting, the ejection member 20 is pulled backward.
That is, the tilting member 21 contracts as shown in FIG.

The tilting speed of the ejection member 20 and the blind plate 19 is higher in the ejection member 20 than in the blind plate 19.
That is, the ejection member 20 discharges the cleaning water W from the ejection port 24, and thus has little resistance to being pulled back.
On the other hand, on the cylinder 12 side, it is necessary to return the washing water W in the large-diameter portion 12b to the pump section (not shown) of the water storage device 27, so that the resistance to the retraction of the piston 16 is large. Therefore, after the ejection member 20 tilts in the retraction direction, the blindfold plate 19 tilts in the retraction direction.
The ejection member 20 does not interfere with the blind plate 19, and the blind plate 19 does not hinder the tilting of the ejection member 20.

When the sanitary washing device of this embodiment is detached from the toilet 1, the suction cup 11 of the support 10 with respect to the toilet 1 is used.
This is done by releasing the adsorption.

According to the present embodiment, the blind plate 19 and the ejection member 20
Can be tilted by the water pressure of the washing water W, so that a power supply for the operation of the ejection member 20 is not required, and it is possible to contribute to energy saving. Also, according to this example,
By making the support body 10 have substantially the same thickness as that between the toilet 1 and the toilet seat 4, the support body 10 can be disposed below the existing toilet seat 4, so that a dedicated toilet seat can be dispensed with and sanitary washing can be performed. The device and its mounting cost can be reduced, and it can be easily attached and detached.

[0040]

According to the present invention, since the tilting member can be expanded and contracted by the water pressure of the washing water, the jetting member can be tilted by the expansion and contraction, and a power source for the operation of the jetting member can be eliminated, thereby saving energy. Can contribute to

Further, by making the thickness of the support substantially the same as that between the toilet and the toilet seat, the support can be disposed below the existing toilet seat, so that a dedicated toilet seat can be dispensed with and the sanitary washing can be performed. The device and its mounting cost can be reduced, and it can be easily attached and detached.
