Generally, this device is configured to perform anal cleaning after defecation (hereinafter referred to as "shower cleaning") and female genital cleaning (hereinafter referred to as "bidet cleaning"). In some cases, if you want to use a shower immediately after washing the bidet, the nozzle does not move to the shower washing position due to its structure, and high-pressure water is ejected at the bidet washing position, causing discomfort to the user. Ta.

The present invention aims to eliminate such drawbacks, and includes a single cylinder fixed to a fixed ceramic wall, a first piston body and a second piston body that are slidable within the cylinder, and a single cylinder fixed to a fixed ceramic wall. a nozzle having one end fixed to the second piston body, a jet opening formed in the other end, and biased backward by a biasing means; a fixed tubular member whose other end is open; a passage hole provided in the tubular member that opens only near the end point of the nozzle; and the first piston body and the second piston body. a first space formed in the tubular member, a one-way valve means or a wall member installed in the tubular member, and a second space at the rear of the first piston body for supplying high-pressure water to the first space. and line means capable of delivering low pressure water through a valve.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a cross section of the water supply line after cleaning according to the present invention and the nozzle cylinder portion of the device.

First, prior to explaining the configuration of the main parts of the present invention, the water supply system will be described.

That is, 1 is a water supply tank, and the water supplied from the tank passes through a filter 2, is sucked and discharged by a pump 3, and reaches a switching valve 5 via a water volume control valve 4. Reference numeral 6 denotes an operating lever, which is rotated between the positions shown by the solid line (shower cleaning) and the two-dot chain line (bidet cleaning) to change the water supply amount and its pressure according to the purpose. 7 is a hot water tank, equipped with a heater 8 and a thermostat 9,
10 is a current plate, 11 is a discharge port, and 12 is a check valve connected to an overflow line 13.

A solenoid valve 14 is provided in a line 16 branching from the water supply line 15 from the discharge port 11, and the outlet of the solenoid valve 14 is connected to the line 17.

The solenoid valve 14 is electrically closed when the operating lever 6 is in the position shown by the solid line, ie, shower cleaning, and is opened when the operating lever 6 is in the position shown by the two-dot chain line, bidet cleaning.

Next, the description will move on to the cylinder nozzle device.

Reference numeral 18 denotes a ceramic wall of the toilet bowl, and the front (right side in the figure; the same applies hereinafter) end of the fixed cylinder 19 is fixed via a seat plate member 20 and a packing 21 with a nut 22 on its threaded portion and a tightening member 22a. Through holes 23a and 23b are provided at the rear end (left side in the figure; the same applies hereinafter) of the fixed cylinder 19. The former through hole 23a is provided in the middle of the auxiliary fixed cylinder 24 which is welded and fixed to the fixed cylinder 19, and the latter through hole 23b is provided in the middle of the cap member 25 which is screwed and fixed to the rear opening of the fixed cylinder 24. It is located in the center. As a result, ceramic wall 18
A fixing member 30, which is paired with the fixing cylinder 19, an auxiliary fixing cylinder 24, and a cap member 25, is formed.

A first piston body 26 is mounted inside the auxiliary fixed cylinder 24 and is slidable on its inner peripheral surface, and one end of a tubular member 27 is welded and fixed to the front side of the center of the piston body 26. .

On the other hand, a stopper 28 is screwed and fixed to the rear open end of the fixed cylinder 19, and the tubular member 27 extends through the inside thereof. A second piston body 29 is disposed inside the fixed cylinder 19 such that its outer circumferential surface is slidable on the inner circumferential surface of the fixed cylinder 19 . The piston body 29 is
Since the piston body 29 is biased rearward by a spring 31 mounted on the front thereof, the rear end surface of the piston body 29 normally contacts the front end surface of the stopper 28.

A tubular nozzle 32 is screwed and fixed to the front side of the second piston body 29, and a shoulder portion 32a is formed on the inner circumferential surface of the intermediate portion of the nozzle 32, and three jet ports 32b are formed at the front end. is bored, and a stopper 33 is fixed to the front opening end.

Another shoulder portion 32c is formed near the spout 32b, and the front end of the locking member 34 screwed and fixed to the front end of the tubular member 27 is in the normal state as shown in FIG. 1 (when using the present device). In the non-contact state), it is arranged so as to almost abut on the shoulder portion 32c. A small spring 35 is attached to the rear end side of the locking member 34. Further, a ring-shaped stopper 36 is attached to the rear end side of the aforementioned tightening member 22a, and one end of the aforementioned spring 31 is latched to the rear end surface of this stopper 36.

One hole 27a and one hole 27b are bored in the middle and rear end of the tubular member 27, and the hole 27
A rubber valve 37 is fixed in the tube slightly forward of b. This valve 37 is a check valve that only allows water to pass in the direction of arrow a, that is, backward.

A slight gap 38 is provided between the outer circumference of the tubular member 27 and the inner circumference of the nozzle 32. Although it is better not to have this gap 38, since it increases sliding resistance, it is provided to such an extent that it does not interfere with operation and use.

Note that the first piston body 26 and the second piston body 29
A space 39 is formed between the tubular member 2 and
Spaces 40 and 41 are formed in front and rear of the valve 37 in the valve 7, respectively. Further, another space 42 is formed in the rear part of the first piston body 26.

Next, we will discuss the effect.

During shower cleaning, that is, when the operating lever 6 is in the solid line position shown in the first figure, the solenoid valve 14 is in the closed state, so water from the hot water tank 7 is sent only to one of the through holes 23a. As a result, the water pressure infiltrates as indicated by arrow b in FIG. 1, and moves the second piston body 29 forward against the spring 31. The piston body 29 and the nozzle 3
2 moves forward until the shoulder portion 32a abuts against the locking member 34 via the small spring 35. At the same time that the small spring 35 begins to bend, the hole 27
Since point a is set to start opening as shown in FIG. 2, water flows as shown by arrow c and is vigorously ejected upward from the outlet 32b at the tip of the nozzle 32. This allows desired shower cleaning.

Here, in this embodiment, when the operating lever 6 is at the solid line position, water flows through the large diameter hole 5a;
At the position indicated by the two-dot chain line, water is configured to flow through the small-diameter hole 5b, so that high-pressure water is sent during shower cleaning, and low-pressure water is sent during bidet cleaning. (However, there are various other ways to change the pressure, such as electrically controlling the rotation speed of the pump.) Also,
In this embodiment, the power is turned off when the lever 6 is turned in the direction of the arrow d from the solid line position.

Therefore, when the user turns the lever 6 in the direction of the arrow from the shower cleaning position (solid line position) or the bidet cleaning position (double-dashed line position), the water pressure in the space 39 is The tank 7 and the overflow line 13 are discharged in this order, and the space 42
The water pressure is discharged to the outside through the through hole 23b and the orifice e. However, water in the space 40 passes through the check valve 37 in the direction a, and is discharged from the line 13 via the hole 27b, the space 39, and the system path 15.

Next, let's talk about bidet cleaning. When the operating lever 6 in FIG.
Water from 1 is sent to both through holes 23a and 23b. The water pressure in the through hole 23b acts on the first piston body 26, causing both the first piston body 26 and the large piston body 29 in the first illustration to move forward together. That is, the first piston body 26 advances by m until it abuts the stopper 28, and the second piston body 29 advances until its shoulder 32a abuts the locking member 34, as in the case of shower cleaning described above.
In this case, since the locking member 34 is moved forward by m more than during shower cleaning, the position of the spout 32b ends up being moved forward by m more during bidet cleaning than during shower cleaning. In this state that the water has advanced a lot, the water advances from the hole 27a as shown by the arrow c (Fig. 2) in the same manner as described above, and reaches the spout 3 at the tip.
It erupts from 2b. As a result, the desired bidet cleaning can be performed.

Here, when the lever 6 is moved from the two-dot chain line position to the immediate solid line position, that is, from the bidet cleaning position to the immediate shower cleaning position, the space 42 is released to the atmosphere via the orifice e, and the space 39 is Water under high pressure is sent through the through hole 23a, and the first piston body 26 is therefore pushed rearward. Further, the second piston body 29 is also integrally pushed rearward from the front position as shown in FIG. On the other hand, the water in the rear part of the first piston body 26 is
6 is discharged to the outside through the hole 23b and the orifice e. Therefore, even when switching from bidet cleaning to shower cleaning immediately, the device of the present invention operates smoothly.

In the above embodiment, a check valve 37 is disposed within the tubular member 27. This valve 37 is provided to quickly release water in the direction a so that water does not remain in the tubular member 27 or the tip of the nozzle 32 when the user stops using it. do. That is, a wall member may be fixed instead of the valve 37.

In this way, the present invention includes a fixing member fixed to a ceramic wall, a first piston body and a second piston body that are slidable within the fixing member, and one end of which is fixed to the second piston body and the other end of the piston body. a nozzle having a spout formed therein and biased backward by a biasing means; and a tubular member disposed within the nozzle, one end fixed to the first piston body and the other end open. a passage hole that is provided in the tubular member and opens only near the end point of the nozzle when it advances;
a first space formed between a piston body and a second piston body; a one-way valve means or a wall member mounted within the tubular member; and high pressure water is supplied to the first space. The second space at the rear of the piston body is comprised of a system that can send low-pressure water through a valve, so when you want to shower with water immediately after cleaning the bidet, as in the conventional case, the nozzle can be used for shower cleaning. Therefore, water under high pressure will not be ejected at the bidet cleaning position and will not harm the user's feeling. Furthermore, the structure of the device of the present invention allows for a single cylinder, and the outer diameter of the cylinder can be made smaller than conventional ones, which contributes to material cost savings and ease of assembly. In addition, the part in front of the ceramic wall, which is visible to the user, can be compacted.
It can also contribute to improving the appearance.

Furthermore, since the configuration eliminates the conventional elastic seal member fixed to the center of the cap member, there is no possibility of sealing failure due to the elastic seal member becoming worn out or the return spring becoming worn out. does not occur, so that reliability of operation can be envisaged.
