Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sanitary device that can comfortably and hygienically clean private parts of the human body.

[Conventional technology]

A sanitary device that has a toilet bowl with a private parts cleaning function is typically equipped with a nozzle for cleaning private parts, and cleans the private parts by feeding cleansing water at an appropriate temperature into the nozzle and jetting out the cleansing water. Then, equipment for controlling the flow rate, temperature, nozzle operation, etc. of the flushing water is attached, as well as the piping system and electrical system are housed in the casing, and this casing is fixed to the toilet body.
When a person sits on the toilet seat, cleansing water is sprayed from the nozzle to cleanse their private parts.

[Problem to be solved by the invention]

In sanitary devices, since the object to be cleaned is a private part of the human body, it is required to provide a soft cleaning sensation, and the flow rate of washing water for private part cleaning is limited to a relatively small amount. On the other hand, when using water, it is also required that the water be used only once so that it can be detected by a water meter.

However, the optimal amount of water required for cleaning is so small that it is less than the minimum amount of water that can be detected by a water meter (known as the insensitive water amount, currently 50/h). Therefore, when installing the sanitary device in a general household, etc., it is not possible to directly incorporate the sanitary device into the toilet bowl body, and it is necessary to modify the piping system so that more water than the insensitive amount flows through the water meter.

To solve this problem, it is conceivable to provide a flow path for discharging water toward the toilet bowl in addition to the flow path toward the nozzle so that water exceeding the insensible amount can be supplied. That is, by providing two flow paths and supplying extra water, the amount of water passing through the water meter can be set to be greater than the insensitive water amount.

However, when using two flow paths like this, it is necessary to incorporate various valves so that cleansing water with stable water pressure can be supplied from the nozzle, and appropriate valves are also required in the piping leading to the toilet bowl. For this reason, the piping space becomes larger than in the case of a single flow path, which tends to cause trouble in the layout of internal equipment of the sanitary device.

Therefore, the present invention aims to make it possible to use the system comfortably without taking up too much piping space or fluctuating the jetting pressure of cleaning water from the nozzle, even if the system has two flow paths as a countermeasure against insensitive water flow. The purpose is to

[Means to solve the problem]

The present invention includes a toilet bowl and a discharge section that discharges cleansing water to a human body, and the supplied flush water is directed to a first flow path toward the discharge section through a distribution section and a drainage path to the toilet bowl. A sanitary device having a second flow path branched into the first flow path, wherein the flow rate of water from the distribution section can be set by external operation, and the flow rate of water from the distribution section can be set to the first flow path, and fluctuations in supply water pressure can be absorbed. A flow rate adjustment valve having a valve mechanism capable of maintaining a set flow rate is provided, and the second flow path is further provided with a water pressure responsive type flow rate adjustment that increases the valve opening in proportion to the flow pressure of water from the distribution section. It is characterized by having a valve.

[Effect]

Since the first flow path toward the discharge section is provided with a flow rate adjustment valve that sets the flow rate of the wash water, the water pressure of the wash water from the discharge section can be appropriately set by throttling the flow rate according to the supply water pressure. In addition, this flow rate adjustment valve is
Fluctuations in the supply water pressure are absorbed so that a set flow rate of water is always directed toward the discharge section, so fluctuations in the water pressure of the cleaning water from the discharge section are also eliminated.

Furthermore, since the flow rate adjustment valve installed in the second flow path toward the toilet side is water pressure responsive, for example, when the flow rate in the first flow path is reduced, the water pressure in the second flow path increases, and the flow rate is increased accordingly. It becomes possible to perform operations such as Therefore, the flow rate adjustment valve in the second flow path can operate in conjunction with the adjustment of the flow rate adjustment valve in the first flow path, and there is no need for a valve opening adjustment mechanism, adjustment knob, etc., and the size can be reduced. becomes.

〔Example〕

This embodiment shows an example in which the washing water flow path is branched to provide two flow paths, and each of the two flow paths is provided with a flow rate adjustment valve in which a constant flow section and a flow rate adjustment section are integrally attached.

In the center of the casing 5 of the sanitary device main body A,
A discharge part a equipped with a nozzle and the like for cleaning private parts is formed to face the bowl part of the toilet bowl 1. A retractable nozzle (described later) that can move forward and backward is provided with an inlet/outlet 5a in the discharge part a, and a warm air outlet 5b is provided on the left side of the outlet 5a to blow out hot air from the hot air fan A-2.

A piping system for supplying cleaning water is provided from the cleaning water supply device A-1 to the discharge section a, and in order to counteract the insensitive amount of water, there is a first flow path toward the discharge section a and a piping system for discharging excess water. A second flow path is provided, respectively.

FIG. 15 is a flowchart showing an outline of the flow path system.

In the figure, water supply source X such as water pipes and discharge part a
A distribution section b is disposed between the distribution section b and a flow path branching from the distribution section b toward a route Y for discharging excess water. The distribution part b connects the inlet 9 to the main flow path 12 from the water supply source X, and connects the first outlet 10 and the second outlet 1
1 are connected to a first flow path 13 heading toward the discharge portion a and a second flow path 14 heading toward the drainage path Y, respectively. With such a system, part of the water supplied from the water pipe part is discharged from route Y.

FIG. 16 is a flowchart showing the system for discharging wash water and excess water in more detail.

The discharge part a is provided with a discharge port 6 for discharging cleansing water to the private parts and a discharge port 7 for discharging excess water to the toilet bowl 1. On the other hand, the main flow path 12 connected to the water supply source X includes the wash water tank 2 and the wash water supply device A-
1 is provided with a branch fitting 15 that separates the water supply,
An on-off valve 16 for supplying and stopping the discharge portion a is provided. Further, a three-way connector 8 is provided downstream of the on-off valve 16 as a distribution part b, and its inlet port 9
is connected to the main flow path 12. The first and second outlet ports 10 and 11 of the three-way connector 8 are connected to a first flow path 13 and a second flow path 14, respectively. The first flow path 13 has a flow rate adjustment valve 17, a heater 18, an intake valve 19, and a vacuum breaker valve 20 arranged in this order up to the water spout 6. On the other hand, the second flow path 14 has a vacuum breaker valve 21 and a flow rate adjustment valve 22 arranged downstream, so that surplus water can be discharged from the discharge port 7 to the bowl portion of the toilet bowl 1 .

Such a flow path system for washing water and surplus water will be explained using a specific structural example.

The main parts of the wash water supply device A-1 are arranged on the left side inside the casing 5, as shown in FIG. FIG. 3 is a longitudinal cross-sectional view showing the inside of the left end of the casing 5, in which one end of the connecting fitting 23 attached to the back surface of the casing 5 is connected to a water conduit pipe 22 such as a copper pipe.
and is connected to the water supply source X via a branch fitting (not shown). The other end of the connecting fitting 23 is connected to a water conduit 25 such as a copper pipe, and this water conduit 25 communicates with the inlet 9 of the three-way connector 8 via a manually operated on-off valve 16. In addition, the water conduit 2 up to the three-way connector 8
4 and 25 correspond to the main flow path 12 shown in FIG.

The on-off valve 16 is a manual type, and its handle 2
8 protrudes from the inclined surface of the side of the casing 5 so that the toilet seat 3 can be easily operated while remaining warm. FIG. 7 is a longitudinal sectional view of the on-off valve 16, in which the valve housing 16a is connected to the mounting plate 5c of the casing 5.
A handle 28 protrudes from the case 5 and is fixed by a nut 16d and a decorative nut 16e. Then, if you operate the opening/closing handle 28,
Water flows into the valve housing 16a from the inlet 16b, flows out from the outlet 16c, and reaches the inlet 9 of the three-way connector 8. Note that a solenoid valve or the like may be used as the on-off valve 16.

The three-way connector 8 is connected to the main channel 1 as shown in FIG.
2 into the first flow path 13 and the second flow path 14
It is made up of tubes, etc. Water flows in from the inlet 9 of the three-way connector 8, branches off from the first outlet 10 and the second outlet 11, and flows out into the first flow path 13 and the second flow path 14, respectively. This three-way connector 8 distributes the flow rate of the main flow path 12 into a first flow path 13 and a second flow path 14, and a flow rate adjustment valve 17 that adjusts the amount of water flowing through each of the first and second flow paths 13 and 14, 22 determines the flow rate of each channel. In this case, the flow rate in the main channel 12 connected to the water supply source
Make sure your water meter shows when water is being used.

FIG. 9 shows the flow rate regulating valve 1 disposed in the first flow path 13.
7 is a vertical cross-sectional view, and FIG. 10 is a vertical cross-sectional view of the flow rate regulating valve 22 provided in the second flow path 14.

The flow rate adjustment valve 17 includes an inlet 17b and an outlet 17c at both ends of a valve housing 17a, and has a first flow path 13.
connected to the system. Inside, there is a flow rate adjustment valve section 33 that adjusts the amount of water flowing in, a diaphragm 34 that senses water pressure fluctuations and automatically adjusts the opening of the flow rate adjustment valve section 33, and a coil spring 35 that holds the flow rate adjustment valve section 33 from above and below. , 36, and coil spring 35
A flow rate adjustment knob 37 is provided to manually adjust the elastic force of the flow rate adjustment knob 37.

In this flow rate regulating valve 17, when water is flowing, the elastic force of the coil springs 35, 36 and the water pressure applied to the diaphragm 34 are balanced, and the water flows through the first outlet 10 of the three-way connector 8, the flow rate It flows out through the inlet 17b of the regulating valve 17, the flow rate regulating valve part 33, the outlet 17c, and reaches the heater 18.
On the other hand, when the flow rate adjustment knob 37 is rotated and the coil spring 35 is pressed downward, the opening degree of the flow rate adjustment valve section 33 is increased and the flow rate can be increased. can be reduced. Therefore, by rotating the flow rate adjustment knob 37, the flow rate of the cleaning water toward the discharge portion a can be adjusted to an arbitrary value.

Furthermore, when the water pressure in the first flow path 13 increases, the diaphragm 34 moves upward against the elastic force of the coil spring 35. Therefore, the opening degree of the flow rate regulating valve section 33 becomes small, suppressing the amount of water and keeping the flow rate constant. Conversely, when the water pressure decreases, the opening degree of the flow rate regulating valve section 33 increases and operates to increase the flow rate. In this way, by using the diaphragm 34, in addition to adjusting the flow rate, it is possible to have the function of a constant flow valve that can maintain the flow rate constant even when the water pressure fluctuates. always maintained constant.

Flow rate adjustment valve 2 provided in the second flow path 14 in FIG.
2 has a piston-type valve body 3 in its valve housing 22a.
8 is housed and is urged toward the inlet 22b by a coil spring 38a. The valve body 38 includes a main small passage 39 that always maintains communication between the inlet 22b and the outlet 22c, and a main small passage 39 that maintains communication between the inlet 22b and the outlet 22c. The secondary passage 41 is closed. Further, an appropriate number of depressurizing nets 22d are provided at the outlet 22c to reduce the force of the water flowing out. Note that this net 22d is not necessarily necessary.

In this flow rate regulating valve 22, the inlet 22b
When the water pressure of surplus water flowing in from is low, valve body 3
8 is pushed away from the valve seat packing 40 by the coil spring 38a. Therefore, the water is at the valve body 3.
The water flows through both the main small passage 39 and the sub-small passage 41 of No. 8 and flows away from the outlet 22c to the discharge port 7 side. Conversely, when the water pressure is high, the valve body 38
The end face of the valve seat gasket 40 moves against the elastic force of the valve seat gasket 40, and the sub passage 41 is closed. Therefore, since water is supplied from the outlet 22c through only the main passage 39 of the valve body 38, the flow rate is suppressed by the amount supplied from the subsidiary passage 41.

Note that the flow rate regulating valves 17 and 22 provided in the first and second flow paths 13 and 14 can also be replaced with each other. That is, the flow rate adjustment valve 22 is used in the first flow path 13, and the flow rate adjustment valve 17 is incorporated in the second flow path 14. Further, as another example, a flow rate regulating valve as shown in FIG. 11 or FIG. 12 can also be used.

In the example shown in FIG. 11, a piston-type valve body 43 housed in a valve housing 42 moves in response to water pressure, thereby creating a plurality of small passages 4 communicating with the outlet 42b.
4, 45, and 46 are closed in sequence. That is, an annular groove 43a is provided on the outer periphery of the valve body 43, and a passage 43 with this annular groove 43a formed inside the valve body 43.
b communicates with the inlet 42a side. The annular groove 43a also communicates with the outlet 42b through small passages 44-46. The small passages 44, 45, and 46 are formed so that their inner diameters gradually become smaller in this order, and the valve body 43 is connected to the spring 44.
7 toward the inlet port 42b.

In such a flow rate regulating valve, when the water pressure is low, the valve body 43 is pushed by the coil spring 47 and does not move (the state shown in the figure). Therefore, water flows from the inlet 42a, passes through the passage 43b, the annular groove 43a, passes through all the small passages 44 to 46, and then flows out from the outlet 42b. On the other hand, when the water pressure becomes slightly higher, the valve body 4
3 moves to the right in the figure to close the small passage 44 located on the leftmost side. Therefore, the water is restricted to only the small passages 45 and 46 as flow paths, and the amount of water is somewhat suppressed. When the water pressure further increases, the valve body 43 moves further to the right to the limit and closes the small passages 44, 45. Therefore, the water flows out only through the small passage 46 and is minimized and the amount of water is reduced.

The flow rate regulating valve shown in FIG. 12 has a valve body 49 made of rubber or the like that can be deformed by water pressure installed in a valve housing 48, and an inlet 48a and an outlet 4 are connected to the valve body 49.
It has a configuration in which a valve hole 49a is opened to establish communication between the valve holes 8b and 8b. In this example, when the water pressure is low, the valve body 4
9 is not deformed, the diameters of the inlet and outlet sides of the valve hole 49a of the valve body 49 remain unchanged.
The minimum water flow area of the valve hole 49a is wide. Conversely, when the water pressure is high, the valve body 49 is deformed into a curved shape convex to the right in the figure by the water pressure. Therefore, the valve hole 49a has a tapered cross-section of the flow path in which the diameter on the inlet side is smaller than that on the outlet side. Therefore, the minimum water flow area of the valve hole 49a is narrowed and constricted, and the amount of water is suppressed. In this way, by using the valve body 49 made of an elastic material such as rubber, the flow rate can be kept constant despite fluctuations in water pressure.

In addition to these, any other type of flow rate regulating valve may be used, such as a needle valve or a fixed throttle.

A heater 18 disposed downstream of the flow rate regulating valve 17 in the first flow path 13 is housed in a side portion of the casing 5, as shown in FIG. Heater 18
are a large diameter pipe 26a and a small diameter pipe 26b made of metal such as copper.
A heat exchanger tube 26 formed in a meandering shape by combining
It is constituted by a planar heating element 27 that heats from the outside of the heat exchanger tube 26. And the flow rate adjustment valve 1
The water in the first flow path 13 that has passed through the heat exchanger tube 26 is automatically heated to an appropriate temperature while flowing through the heat transfer tube 26, becomes hot water for cleaning, and is supplied to the discharge part a. Note that as another structural example of the heater 18, a tank or the like that is directly heated with a sheathed heater or the like may be used.

FIG. 13 is a sectional view of vacuum breaker valves 20 and 21 incorporated in both the first and second flow paths 13 and 14. As shown in the figure, an air valve 51 that opens and closes between the outlet 50b and the air hole 50c and a water valve 52 that opens and closes between the inlet 50a and the outlet 50b are installed in the valve housing 50 using the same EPDM or the like. They are provided on the upper and lower surfaces of a synthetic resin valve body 53, respectively. When water flows, the water pressure at the inlet 50a pushes up the valve body 53, opening the water valve 52, and at the same time, the air valve 51 closes as the inlet 50a and outlet 50b communicate with each other. Further, when the flow of water stops, the valve body 53 descends due to its own weight, the water valve 52 is closed, and at the same time the air valve 51 is opened. By closing the flow path and opening to the atmosphere, the outlet 50b communicates with the air hole 50c, the vacuum state is broken, and backflow of water is prevented.

FIG. 14 is a longitudinal cross-sectional view of the intake valve 19 provided between the heater 18 and the vacuum breaker valve 20 in the first flow path 13. As shown in the figure, an air valve 55 that opens and closes between an outlet 54b and an air hole 54c provided in the valve housing 54, and a water valve 56 provided on the opposite side of the air valve 55 are connected to a valve body 57 made of EPDM. It is provided on the upper and lower surfaces of the A narrow groove 56a is formed in the seating surface of the water valve 56, and the inlet 54a and outlet 54 are always connected to each other.
4b is in communication.

In this configuration of the intake valve 19, when water flows, the valve body 57 is pushed up by the water pressure of the water flowing in from the inlet 54a, and the air valve 55 closes the air hole 54c. Moreover, when the flow of water stops, the valve body 57 descends due to its own weight and the air hole 54c
open. Therefore, the outflow port 54b communicates with the air hole 54c and the vacuum state is broken, and at the same time the water valve 56
The inlet 54a is connected to the air hole 54 by the narrow groove 56a.
The vacuum state of the heat transfer tube 26 of the heater 18 connected to the inlet port 54a is destroyed.

FIG. 4 is a longitudinal sectional view showing how the casing 5 of the discharge section a provided at the ends of the first and second flow paths 13 and 14 is assembled. This discharge part a is arranged approximately in the center of the casing 5, and has a configuration in which a cleaning nozzle 59 can be moved forward and backward from the inlet/outlet 5a toward the bowl part of the toilet bowl 1.

FIGS. 5 and 6 are a partially cutaway plan view and a vertical cross-sectional view, respectively, showing the nozzle structure of the discharge part a.

The discharge part a includes a cylinder 58 fixed within the casing 5, and a nozzle 59 slidably housed within the cylinder 58 and advanced to the cleaning position. The cylinder 58 is provided with a cleaning water supply port 58a connected to the first channel 13 and a surplus water supply port 58b communicating with the second channel 14. Cleaning water supply port 58a
can communicate with the discharge port 6 via a through passage 59c of a piston-type nozzle 59 housed in the cylinder 58. Moreover, the surplus water supply port 58b is
A small passage 60 provided in the cylinder 58 communicates with the discharge port 7 .

When the cleaning water is supplied from the cleaning water supply port 58a, the piston portion 59a provided at the base end of the nozzle 59 receives water pressure, and the nozzle 59 advances to the cleaning position as shown by the dashed line in FIG. At this time, cleaning water flows into the through passage 59c from a small hole in the pressure receiving plate 67 provided at the base end of the nozzle 59, and is supplied to the water spout 6 at the tip. Then, the cylinder 5 passes through a cut (not shown) in the U packing 61 provided on the piston portion 59a
8 and the small diameter portion of the nozzle 59.
flows into c. This inflow water is discharged into the toilet bowl 1 through a discharge hole 58d formed in the distal end surface of the cylinder 58, and the structure is such that residual hot water between the heater 18 and the discharge part a escapes. When the nozzle 59 has completely advanced to the cleaning position, the front surface of the piston part 59a comes into contact with the gasket 62, and at the same time, the hot water stops being discharged from the discharge hole 58d, and at the same time, the cleaning water is discharged from the discharge part 6 at the tip of the nozzle 59. It gushes out vigorously.

In addition, a knob 63a is provided on the outer periphery of the tip of the nozzle 59.
Nozzle switching tube 63 that can be rotated 180 degrees by operating
is installed. This nozzle switching cylinder 63 is prevented from coming off by a retaining ring 64, and discharge ports 6a and 6b are formed in the upper and lower side walls of the nozzle 59, respectively, so as to correspond to the openings 59b provided on the upper surface of the tip of the nozzle 59. One outlet 6a has a single opening with a rather large diameter, and the other outlet 6b has a plurality of holes with a relatively small diameter. Then, by switching the knob 63a,
Selectively open 59 one of the discharge ports 6a and 6b.
According to b, a desired discharge form such as a nozzle shape or a shower shape can be used.

Note that 58e is a positioning stopper for the knob 63a, which is incorporated so as to protrude from the opening 5a of the case 5. This stopper 58e also serves to prevent dirty water from splashing onto the switching tube 63 when the discharge portion a is not in use. Also, 6
5 is a screw that prevents the nozzle 59 from being stopped. Further, in FIG. 5, the spout 6 is shown as a representative in order to match the numbering with the flowchart in FIG. 16.

On the other hand, the nozzle 59 is constantly urged by a coil spring 66 in the direction of being housed in the cylinder 58. For this reason, the nozzle 59 is always housed in the casing 5 and is not visible from the outside while cleaning water is not being supplied.

Here, when the cleaning water from the first channel 13 and the surplus water from the second channel 14 are supplied to the cleaning water supply port 58a and the surplus water supply port 58b, respectively, the surplus water flows into the inside of the cylinder 58. Small passage 60 formed
The cleaning water flows into the through passage 59c from the small hole of the pressure receiving plate 67. The surplus water supplied to the small passage 60 is discharged from the outlet 7 at the end of the small passage,
At this time, the water flows down into the bowl of the toilet bowl 1 while cleaning the tip of the nozzle 59. On the other hand, the water pressure of the cleaning water flowing from the cleaning water supply port 58a is applied to the nozzle 5.
9 acts on a pressure receiving plate 67 provided on the piston portion 59a. Therefore, the nozzle 59 moves toward the toilet bowl 1 against the biasing force of the coil spring 66, protrudes from the opening 5a of the casing 5, and advances to the cleaning position.

In this manner, when the cleaning water is supplied, the nozzle 59 advances to the cleaning position due to the water pressure, and the cleaning water is spouted from the water spout 6. Moreover, surplus water flowing in at the same time as the cleaning water is supplied is discarded from a system different from the flow path to the water spout 6. The upstream side of the three-way connector 8 constituting the distribution part b has a combined flow rate of these wash waters and surplus water, and this flow rate is set above the insensitive water amount to meet the flow rate necessary for private washing. If only the amount of water is sent to the discharge part a and the rest is discarded as surplus water, the problem with the amount of insensitive water can be solved. Therefore, it can be widely used for general household use without being subject to installation restrictions.

In addition, since flow rate adjustment valves 17 and 22 are provided in each of the first flow path 13 to the discharge part a and the second flow path 14 for disposing of surplus water, it can be adapted to installation conditions with different water supply pressures, etc. be able to. That is, the flow rate adjustment valve 17 provided in the first flow path 13 can adjust the flow rate to the discharge part a by its flow rate adjustment knob 37, and when the water supply pressure is low, the valve opening degree is increased to ensure the amount of cleaning water. Conversely, when the water supply pressure is high, the amount of washing water can be reduced by throttling. Therefore, even if the water supply pressure varies depending on the installation conditions, the amount of washing water to be supplied to the discharge portion a can be set to an appropriate amount. Furthermore, since the flow rate adjustment valve 17 includes a diaphragm 34 that responds to water pressure, the valve opening degree is increased or decreased to maintain a constant flow rate even in response to water pressure fluctuations.
Therefore, even if there is a change in not only the flow rate setting but also the water supply pressure, the force of the washing water from the discharge part a does not change, making it possible to perform comfortable washing.

Furthermore, a flow rate adjustment valve 22 provided on the second flow path 14 side
Since it is a water pressure responsive type, it can absorb fluctuations in water pressure in the same way as the first flow path 13 side. For this reason,
Even if rapid fluctuations in water supply pressure occur, there is no discontinuity in the flow within the pipe, effectively preventing water hammer phenomena, and preventing damage to members and generation of noise.

In addition, since both the first and second flow paths 13 and 14 are equipped with flow rate adjustment valves 17 and 22, when the flow rate is set to the insensitive water level or more downstream of the distribution part b (three-way connector 8), the discharge The flow rate to the part a side and the waste side can be set appropriately. That is, when the flow path is throttled by the manually operable flow rate adjustment valve 17 on the first flow path 13 side, the flow rate to the second flow path 14 side increases, and conversely, the valve opening degree of the flow rate adjustment valve 17 is reduced. If it is made larger, the flow rate to the second flow path 14 becomes smaller. In this way, the second
Even if the flow rate regulating valve 22 incorporated in the flow path 14 cannot be operated manually, if it is of a water pressure responsive type, the first flow path 1
The flow rates on the discharge side and waste side are determined by the flow rate settings on only the third side. Therefore, the second flow path 14
A small and simple structure can be used as the flow rate regulating valve 22 provided for this purpose, and piping within the casing 5 of limited capacity can be easily performed.

Note that the flowchart is not limited to that shown in FIG. 16, and various modifications are possible. for example,
Heater 18, intake valve 19, vacuum breaker valves 20, 21
etc. may be provided as necessary, and the order of arrangement thereof is also arbitrary. In addition, the branch fitting 15 and the on-off valve 16
does not necessarily need to be provided.

In the above embodiment, an example was specifically explained in which the cleaning water supply channel was divided into two, and a flow rate adjustment valve was provided in each half, in which a constant flow section and a flow rate adjustment section were integrally attached. It goes without saying that, depending on the piping situation, the present invention can be applied to optionally attaching both functional parts in two parts as an embodiment.

〔Effect of the invention〕

In the present invention, the flow rate of cleaning water directed to the discharge section can be appropriately set according to the water supply pressure, and fluctuations in the jetting pressure of the discharged cleaning water can also be suppressed, so the flow rate is always stable under the appropriate flow rate for cleaning. This allows for comfortable cleaning.

In addition, the flow rate adjustment valve on the second flow path side, which was installed as a measure against insensitive water flow, is a water pressure responsive type that changes the flow path area in conjunction with the flow rate adjustment valve on the first flow path side, so there is no mechanism for adjusting the flow rate. Not necessary. Therefore, the piping space can be reduced, and the degree of freedom in the layout of equipment to be housed inside the sanitary device can be improved.
