Abstract

PROBLEM TO BE SOLVED: To make the specifications of a main body common so as to simplify a sanitary cleaning device. SOLUTION: The sanitary cleaning device is designed on the precondition that the pressure resistance and the flow regulation mechanism of a cleaning water tank or jet pressure when cleaning water is jetted from a cleaning nozzle is supplied at low service water pressure (less than 0.1 Mpa). Therefore, to introduce a sanitary cleaning device in areas where service water pressure is low, Southeast Asia for example, pipeline members of a branch pipe must be those having a simple pipeline. On the other hand, to introduce the sanitary cleaning device in areas where service water pressure is higher than the low service water pressure, Japan and Western countries for example, a pipeline member 34A having an orifice in an appropriate position of a pipeline must be used. At such time, the orifice 34b must have the area of the pipeline that is adjusted to obtain a pressure difference between service water pressure in those areas and the low service water pressure, and supply pressure is adjusted by a pressure loss in such orifice 34b.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary washing apparatus having washing means for ejecting washing water toward a human body part and washing the human body part.

[0002]

2. Description of the Related Art This type of sanitary washing apparatus is rapidly spreading because it can keep a local area clean after use. In this sanitary washing apparatus, washing water used for local washing is usually obtained by branching off from a water pipe, and is jetted using tap water pressure.

[0003]

The water pressure of a water pipe is usually fixed, but varies depending on a local government, a national policy, or a local environment. For this reason, when introducing a sanitary washing device, it was necessary to adjust each time according to the tap water pressure of the introduction area. For example, in the United States, tap water pressure is 0.147-0.862 MPa,
In Japan, the pressure is 0.05 to 0.74 MPa. Therefore, if the washing water is jetted at this tap water pressure, an excessive sense of incongruity is given to a local part receiving the jet. Therefore, a pressure adjusting mechanism for lowering the tap water pressure so that the pressure of the wash water jet is about 0.15 MPa {1.5 kgf / cm ² } is prepared according to the tap water pressure in the area. Was built into the body. However, in certain areas such as remote islands, mountainous areas, and Southeast Asia, the above tap water pressure may not be obtained, and in Southeast Asia, most of them are less than 0.1 MPa {1 kgf / cm ² }. Therefore, the sanitary washing device in which the pressure adjusting mechanism is incorporated as described above is not suitable for these specific areas, and the sanitary washing apparatus has to be provided with specifications suitable for such specific areas.

[0004] Further, since the sanitary washing device obtains washing water from a water pipe, it may be obligatory to prevent backflow from the sanitary washing device side. It also needed to be built into the body. Of course, there are areas where such restrictions are not provided, and in this case, a backflow prevention mechanism is not required. That is, since the specifications of the sanitary washing device are diversified, the man-hour for assembling the device is increased and the handling thereof is complicated.

The present invention has been made to solve the above problems, and has as its object to simplify the structure of a sanitary washing device.

[0006]

Means for Solving the Problems and Their Functions and Effects In order to solve the above problems, a sanitary washing apparatus of the present invention comprises a washing means for jetting washing water toward a human body part to wash the human body part. A sanitary washing apparatus comprising: a main body in which the washing means is provided; and a water supply means for guiding the washing water from a water supply source to the washing means, wherein the water supply means is a pipe for guiding the washing water. At least one of a plurality of detachable pipe members prepared as a path is provided, and the pipe member has a control means for controlling washing water flowing through the pipe.

[0007] In the sanitary washing apparatus of the present invention having the above-described structure, the pipe member can be attached and detached and replaced, so that the control means in the pipe member can be appropriately changed to various means. For this reason,
ADVANTAGE OF THE INVENTION According to the sanitary washing apparatus of this invention, since the control means of a pipe member can be made into the specification according to the characteristics of the area, etc., and the specification of an apparatus main body can be unified, the structure can be simplified. . Then, through the simplification of the structure, the number of assembling steps, the cost, and the handling can be reduced. In addition, since the work for adjusting to the characteristics of the region can be performed at a place remote from the apparatus main body through the attachment / detachment / replacement of the pipe member, the workability can be improved.

The sanitary washing device of the present invention can also adopt the following aspects. The first aspect is the sanitary washing device of the present invention described above, wherein the water supply means is used as the control means. The pipe member may include a water pressure control means for reducing the pressure of the cleaning water guided to the cleaning means to a predetermined water pressure or less.

In the sanitary washing apparatus of the first aspect, the use of the pipe member having the water pressure control means allows the water pressure to be adjusted and the washing water to be jetted out, and such a pipe member is not used. Thus, the cleaning water can be spouted without adjusting the water pressure.

In a second aspect, in the sanitary washing apparatus according to the present invention, the water supply means includes a backflow preventing means for preventing a backflow of washing water guided to the washing means as the control means. Can be provided.

In the sanitary washing device according to the second aspect, the backflow of the washing water can be prevented by using the pipe member having the backflow preventing means. In a region where there is no backflow prevention regulation, an excess function can be omitted by using a simple pipe member having no backflow prevention means.

In the sanitary washing device according to the second aspect, the backflow preventing means is provided by opening a gap between the upstream pipe on the water supply source side and the downstream pipe on the cleaning means side. There may be provided a discharge pipe which is provided so as to face the discharge pipe, and which discharges the backflow water flowing backward through the downstream pipe to the outside of the pipe via the gap.

In the sanitary washing device according to the third aspect, when the inflow of the washing water from the upstream pipe is stopped, the air present in the gap between the upstream pipe and the downstream pipe causes the upstream water to flow. Do not place the pipeline and the downstream pipeline in a state where both pipelines are continuously filled with water. For this reason, the siphon effect over the upper and lower pipelines is less likely to occur, and backflow can be prevented. In addition, the backflow water from the downstream pipe can be discharged to the outside of the pipe by the discharge pipe, which is preferable. For example, if the discharge pipe is provided so as to reach the ball portion of the toilet bowl, the backflow water can be guided to the ball portion to be stored water in the ball portion.

In the sanitary washing device according to a second aspect, the backflow prevention means includes an upstream pipe on the water supply source side, a downstream pipe on the cleaning means side, and A float chamber into which a side pipe and a downstream pipe are joined; and an air introduction pipe for introducing air into the float chamber, wherein the float chamber is provided with the washing water from the upstream pipe. Having a float that floats and floats in the float chamber so as to open the atmosphere introduction pipe when the inflow of the washing water from the upstream pipe is stopped when the flow into the chamber is closed. can do.

In the sanitary washing apparatus according to the fourth aspect, when the inflow of washing water from the upstream pipe is stopped, the air introduction pipe is opened by the float in the float chamber, and the float chamber is opened by this pipe opening. Air enters. Therefore, the presence of air in the float chamber between the upstream pipe and the downstream pipe causes the upstream pipe and the downstream pipe to be continuously filled with water. Do not put in. For this reason, the siphon effect over the upper and lower pipelines is less likely to occur, and backflow can be prevented.

[0016]

It is composed of And this sanitary washing device 2
0 is attached to the rear of the Western toilet 21 together with the main body 22, the toilet seat 28 and the lid 29 of the toilet
Open and close. The washing water tank incorporated in the operation unit 26 is separated into a tank for simply storing washing water and a tank having a heater for storing warm water, and water is supplied to both tanks. Further, the cleaning nozzle 24 is housed and arranged in the main body 22, and is configured to advance during local cleaning and to be retracted into the main body after completion of cleaning. Further, water and hot water are supplied to the cleaning nozzle 24 from the two tanks at a predetermined flow ratio, and hot water having a temperature determined by the flow ratio and the like is jetted from the cleaning nozzle 24.

A water supply pipe 31 for supplying water to the low tank 30 branches from a water supply pipe 31 for supplying water to the low tank 30 to a branch pipe 32.
Is plumbed. The branch pipe 32 is connected to a branch plug 33 provided in the middle of the pipe of the water supply pipe 31.
4 and a flexible hose 36 connected to the lower surface of the operation unit 26 of the sanitary washing device 20 by a pipe fitting. Therefore, in the sanitary washing device 20, more specifically, in the washing water tank described above, the water supply pipe 31 is connected to the branch plug 33 and the branch pipe 32.
The washing water is jetted from the washing nozzle 24 using the water supply pressure at this time.

As shown, the branch pipe 32 is provided with a branch plug 3.
3 hangs down from it and curves below it, and the sanitary washing device 20
And a flexible hose 36 forms a range of the pipeline that is a curved pipeline. The flexible hose 36 is a three-layer flexible hose in which an EPDM (ethylene-propylene-diene copolymer) hose is covered with a braided stainless steel wire and further covered with a resin such as vinyl chloride. is there. The upper end of the flexible hose 36 is a steel pipe portion 36a for fixing the pipe member 34.

Branch tap 33 and flexible hose 36
Is formed using a steel pipe or a resin, as shown in the cross-sectional view of FIG. 2, forms a straight pipe at its inner diameter portion 34a, and has fixed flanges 40, 41. The conduit member 34 has bosses 42 and 43 protruding from the fixed flange.
In this case, the upper and lower fixed flanges 40 and 41 have the same outer diameter and thickness, and the bosses 42 and 43 also have the same outer diameter and protrusion length. The boss portion 42 is provided in a fitting hole 33 a provided in the lower end opening of the branch plug 33, and the fitting hole 3 provided in the steel pipe portion 36 a at the upper end of the flexible hose 36.
6b, the boss portions 43 are fitted respectively, and the fixing flange 4
0, 41 are the lower end flange 33b of the branch tap 33, the steel pipe section 3
6a contacts the upper end flange 36c. That is, by fitting the respective bosses into the fitting holes, the conduit members 34 are formed.
Is connected to the branch tap 33 and the flexible hose 36,
A conduit from the branch tap 33 to the flexible hose 36 is formed. Further, the pipe member 34 can be removed by pulling out the boss from the fitting hole. The boss 42,
An O-ring 44 is attached to 43 to make the pipe watertight.

The pipe member 34 connected in this manner is fixed by a fixing bracket 45 as shown in FIG. 3 which is a schematic perspective view of the connection portion. Since the fixing bracket 45 is formed by press-forming a plate material of a high elastic material such as a spring steel plate, when the force for expanding the distal end is removed, the distal end is returned to the original position. A fixing groove 46 into which the lower flange 33b of the branch plug 33 abutted and the fixing flange 40 of the conduit member 34 are formed is formed on the side surface thereof as shown in the figure. Therefore, the fixing bracket 45 is deformed so that the front end thereof is widened, and in this state, the lower end flange 33b and the fixing flange 40 are overlapped to form the fixing groove 4.
6, when the force causing the deformation is removed, the pipe member 34 is fixed by the fixing bracket 45 to the branch plug 33.
Fixed against. The same applies to the flexible hose 36 side.

The following pipe members 34A are prepared in place of the pipe members 34. As shown in the sectional view of FIG.
a orifice part 3 with reduced pipe area
4b. Therefore, when the fluid (washing water in the embodiment) passes through the orifice portion 34b, a pressure loss is caused in accordance with the narrowed pipe area, and the pressure is reduced by that amount to reduce the orifice portion 34b. Wash water flows downstream of. In this case, the pipe area of the orifice portion 34b is set as described later according to the tap water pressure in the area where the sanitary washing device 20 is installed. In FIG. 4, the orifice portion 34b is provided substantially at the center of the conduit member 34. However, it is needless to say that the orifice portion 34b may be provided at the upper and lower end portions of the conduit member 34 and other places. . Alternatively, the orifice portion may be formed of a rubber-like material, and may be a constant flow valve utilizing deformation due to pressure.

In this embodiment, the pressure resistance of the washing water tank built in the operation unit 26 and a flow rate adjusting mechanism (not shown) built in the operation unit or the main body provided between the flexible hose 36 and the washing water tank. Alternatively, when the washing water is ejected from the washing nozzle 24, the jet pressure or the like is set at a low tap water pressure (less than 0.1 MPa) from the branch tap 33 to the branch pipe 3.
It is designed on the premise that the washing water is supplied through 2. Therefore, in order to introduce the sanitary washing device 20 of this embodiment into the above-mentioned low tap water pressure area, for example, an area such as Southeast Asia, the pipe member 34 in the branch pipe 32 must be a simple pipe as shown in FIG. The pipe member 34 having a passage may be used. On the other hand, in order to introduce the system into areas where the tap water pressure is higher than the above-mentioned low tap water pressure, for example, Japan and the US and Europe,
Pipe member 3 having orifice portion 34b as shown in FIG.
In this case, an orifice portion 34b whose pipe area is adjusted to produce a pressure difference between the tap water pressure in the area and the low tap water pressure is used, and the pressure loss at the orifice portion 34b is used. The pressure may be adjusted according to.

Therefore, the sanitary washing device 2 of the above embodiment is used.
0, the pipe members 34 and 34A in the branch pipe 32 are provided.
Through the replacement, the supply pressure of the washing water to the sanitary washing device 20 can be adjusted by the branch pipe 32 itself. For this reason, according to this sanitary washing device 20, it is possible to make the pipe members 34, 34A specifications suitable for the tap water pressure in the area where the sanitary washing device 20 is introduced, and to unify the specifications of the main body 22. Therefore, the structure can be simplified. Then, through the simplification of the structure, it is possible to reduce the number of assembling steps of the sanitary washing device 20, thereby reducing the cost and simplifying the handling. In addition, since the work for adjusting the water pressure can be performed at a place remote from the main body 22 through the attachment / detachment / replacement of the pipe members 34 and 34A, the workability can be improved.

In this embodiment, the upper and lower fixing flanges 40, 41 and the upper and lower bosses 42, 43 have the same shape. For this reason, regardless of the direction of the conduit members 34, 34A, the conduit members 34, 34A can be easily attached, and the replacement work can be simplified. Further, the pipe member 34,
Since the fixing of 34A is only required to expand and deform the fixing bracket 45 and then remove the deformation, the fixing work is also simple.

Next, a case where the above-mentioned sanitary washing device 20 is introduced into an area where it is required to prevent backflow from the sanitary washing device side will be described. In this case,
The following conduit member 34B is used in place of the conduit member 34 described above. As shown in the cross-sectional view of FIG. 5, the pipe member 34 </ b> B has a closed area 51 therein, and the upstream side communicating with the closed area 51 through the boss 42 on the side fixed to the branch tap 33. It has a side conduit 52. An opening / closing solenoid valve 56 driven by a control device (not shown) built in the main body 22 is provided in the middle of the upstream pipeline 52.
Through this opening / closing solenoid valve 56, the upstream pipe 52 sends out the washing water to the downstream closed area 51. The conduit member 34B has a tubular portion 53 that rises from the boss 43 on the side fixed to the flexible hose 36 toward the inside of the closed area 51, and penetrates the boss 43 and the tubular portion 53. And has a downstream pipe 54 communicating with the closed area 51. In this case, the upstream pipe 52 and the downstream pipe 54 are opened so that the axes of the openings at the ends coincide with each other.
Since the tubular portion 53 only rises to almost the center of the closed area 51, the upstream pipeline 52 and the downstream pipeline 54 are opposed to each other with a gap.
The pipe member 34B has a discharge pipe 55 which communicates with the closed area 51 at the base of the tubular portion 53 and discharges the fluid (wash water) in the closed area 51 to the outside of the pipe.

When the pipe member 34B is fixed between the branch tap 33 and the flexible hose 36,
The supply of the cleaning water and the backflow prevention are performed as follows. For example, when the opening / closing solenoid valve 56 is opened and washing water (tap water) flows in from the side of the branch tap 33 through the upstream pipe 52, the washing water flows into the upstream pipe 52 and the closed area 51.
Passes through the downstream pipe 54 and is guided to the sanitary washing device 20 via the flexible hose 36. With the cleaning water thus guided, cleaning water is ejected from the cleaning nozzle 24. On the other hand, when the opening / closing electromagnetic valve 56 closes and the flow of the wash water from the upstream pipe line 52 stops,
Due to the air present in the closed area 51, that is, the air present in the gap between the upstream pipe 52 and the downstream pipe 54,
The upstream pipeline 52 and the downstream pipeline 54 are not placed in a state where both pipelines are continuously filled with water. For this reason, the siphon effect between the upstream pipe 52 and the downstream pipe 54 is less likely to occur, and backflow can be prevented. Also,
When the backflow water flows into the closed area 51 from the downstream pipe 54 side, the backflow water can be discharged from the discharge pipe 55 to the outside of the pipe, which is preferable. For example, the discharge line 55 is
If the water reaches the ball portion, the backflow water can be guided to the ball portion to be stored water in the ball portion.

That is, the main body 2 in the sanitary washing device 20
The backflow can be prevented more suitably by the conduit member 34B without changing the specification of No. 2. On the other hand, in an area where there is no backflow prevention regulation, the pipe member 34 may be used instead of the pipe member 34B. In this case, an excessive function (backflow prevention) can be omitted, and cost can be reduced.

Next, another conduit member 34 for preventing backflow.
C and 34D will be described. As shown in the cross-sectional view of FIG. 6, the conduit member 34C has a float chamber 61 above the boss 43 on the side fixed to the flexible hose 36,
There is a downstream pipe 62 penetrating through the boss 43 and communicating with the float chamber 61. The pipe member 34 </ b> C has an upstream pipe 63 that passes through the boss 42 on the side fixed to the branch tap 33 and reaches the float chamber 61. That is, the conduit member 34C includes the float chamber 61 where the upstream conduit 63 and the downstream conduit 62 are joined. The upstream pipe 63 includes a tubular pipe 63 a on the side of the boss 42, a deformed pipe 63 b connected to the pipe 63 a, and a lower pipe 6 reaching the float chamber 61 from below.
As shown in FIG. 7, which is a cross-sectional view taken along the line 7-7 in FIG. 6, the deformed pipe section 63b has an arc-shaped cross-sectional shape, and has the same flow area as the tubular pipe section 63a. Have been. The lower conduit portion 63c also has a flow area that is substantially equal to that of the tubular conduit portion 63a. In addition, this pipe member 3
4C is divided into upper and lower parts and is bonded in a watertight manner.

In the float chamber 61, the float chamber 61
A float 64 that floats and sinks according to the amount of washing water in the inside is provided. The upper end of the lower conduit portion 63c, which is one conduit portion of the upstream conduit 63, is a lower valve seat 65 with which the float 64 abuts when the float 64 sinks. The pipe member 34C has an air introduction pipe 66 which communicates with the float chamber 61 from above and introduces air into the float chamber 61. At an open end of the air introduction pipe 66 on the float chamber 61 side, An upper valve seat 67 is brought into contact with the float 64 that floats.

When the above-mentioned conduit member 34C is incorporated and fixed between the branch tap 33 and the flexible hose 36,
The supply of the cleaning water and the backflow prevention are performed as follows. Before the flow of the washing water (tap water) from the branch tap 33 side, the float 64 sinks by its own weight and contacts the lower valve seat 65. When washing water (tap water) flows from the branch tap 33 in this state, the washing water is supplied to the upstream pipe 6.
3, the float 64 is slightly pushed up from the lower conduit portion 63c and enters the float chamber 61. Then
The float chamber 61 is filled with the washing water that has flowed in, and the float 64 receives buoyancy and rises from the lower valve seat 65. Therefore, the upstream pipe 63 and the downstream pipe 62 are in communication with each other via the float chamber 61, and the washing water is supplied to the downstream pipe 62.
From the sanitary washing device 2 through the flexible hose 36
It is led to 0. With the cleaning water thus guided, cleaning water is ejected from the cleaning nozzle 24. In this case, the float 64 floats up and comes into contact with the upper valve seat 67, so that the air introduction pipe 66 is closed.

On the other hand, when the inflow of the washing water from the upstream pipe 63 is stopped, the washing water in the float chamber 61 flows out from the downstream pipe 62. Then, with the decrease in the amount of washing water in the float chamber 61, the float 64 sinks and separates from the upper valve seat 67. Therefore, the air introduction pipe 66 is opened and communicates with the float chamber 61. For this reason, air enters the upper end openings of the float chamber 61 and the downstream pipe 62 through the air introduction pipe 66. Therefore, the float chamber 61
The upstream pipe 63 and the downstream pipe 62 are not placed in a state in which both pipes are continuously filled with water due to the air existing in the air and the air that has entered the upper end opening of the downstream pipe 62. . Therefore, the siphon effect between the upstream pipe 63 and the downstream pipe 62 is less likely to occur, and backflow can be prevented.

That is, the main body 2 in the sanitary washing device 20
The backflow can be prevented more suitably by the conduit member 34C without changing the specification of No. 2. On the other hand, in an area where there is no backflow prevention regulation, the pipe member 34 may be used instead of the pipe member 34C. In this case, an excessive function (backflow prevention) can be omitted, and cost can be reduced.

The other conduit member 34D has a closed area 71 therein as shown in the sectional view of FIG.
And an upstream pipe 72 communicating with the closed area 71 through the boss 42 on the side fixed to the boss 42. The pipe member 34
D has a tubular portion 73 that rises from the boss portion 43 on the side fixed to the flexible hose 36 toward the inside of the closed region 71, and penetrates the boss portion 43 and the tubular portion 73 to form the closed region 71. Has a through-hole 74 communicating with the hole. In this case, the lower end portion of the through hole 74 is a downstream pipe 75 through which the washing water passes. A check piece 76 having a T-shaped cross section is incorporated in the closed area 71. The check piece 76 is fixed by fitting its flange portion 76a to the closed area 71 with an elastic ring 77 interposed. Have been. A bottomed inflow hole 76b is formed in the inside of the check piece 76, and outflow ports 76c are equally spaced on the peripheral wall of the inflow hole 76b. A rubber sleeve 78 in the shape of a trumpet is mounted on the check piece 76, and the rubber sleeve 78 is incorporated in the closed area 71 together with the check piece 76. The rubber sleeve 78 holds the check piece 7 in a state expanded in the radial direction.
6 is normally attached to the outlet 6.
c is closed by the rubber sleeve 78. The inner diameter of the through hole 74 is adjusted so that the rubber sleeve 78 can expand in the radial direction.

When the above-mentioned conduit member 34D is incorporated and fixed between the branch tap 33 and the flexible hose 36,
The supply of the cleaning water and the backflow prevention are performed as follows. When the washing water (tap water) flows in from the branch tap 33, this washing water passes through the upstream pipeline 72 and passes through the check piece 7
6 into the inflow hole 76b. Since the lower end of the inflow hole 76b is closed, the pressure of the washing water that has entered enters the rubber sleeve 78 from the outflow port 76c. Therefore, the rubber sleeve 78 is expanded in the radial direction, and a gap is formed between the rubber sleeve 78 and the peripheral wall of the inflow hole 76b. Therefore, the washing water that has entered the inflow hole 76b flows out of the outlet 76c into this gap, and flows out to the downstream pipe 75 as indicated by an arrow in the figure. After that, it is led to the sanitary washing device 20 via the flexible hose 36. With the cleaning water thus guided, cleaning water is ejected from the cleaning nozzle 24.

On the other hand, when the inflow of the washing water from the upstream pipe 72 stops, the force for expanding the rubber sleeve 78 in the radial direction disappears, so that the rubber sleeve 78 is attached to the peripheral wall of the inflow hole 76b. In close contact. Therefore, the outlet 76
c is closed, and the rubber sleeve 78 and the inflow hole 7 are closed.
There is no gap between the peripheral wall 6b and the peripheral wall. Therefore, the backflow water flowing backward from the downstream pipe 75 is blocked by the rubber sleeve 78 and does not enter the upstream pipe 72, and the backflow is prevented.

That is, the main body 2 in the sanitary washing device 20
The backflow can be suitably prevented by the conduit member 34D without changing the specifications of the second embodiment. On the other hand, in an area where there is no backflow prevention regulation, the pipe member 34D may be replaced with the pipe member 34. In this case, an excessive function (backflow prevention) can be omitted, and cost can be reduced.

Next, another embodiment of the sanitary washing device 20 to which the pipe member 34 having a simple pipe or the pipe member 34A having an orifice portion 34b is applied will be described.
As shown in FIG. 9, the sanitary washing device 20A has almost the same external shape as the above-described sanitary washing device 20, and includes a low tank 30, a valve seat 28, and the like. However, the operation unit 26
Has only a tank (not shown) for storing the cleaning water supplied from the branch pipe 32, and sends out the cleaning water from the tank to the cleaning nozzle 24a using this water supply pressure (tap water pressure). It is configured to perform flushing water ejection.

The sanitary washing device 20A includes a nozzle advancing / retreating lever 80 and a washing water ejection handle 8
In order to advance and retract the cleaning nozzle 24 by operating the nozzle advance / retreat lever 80, and to eject and stop the washing water from the washing nozzle 24a by operating the washing water ejection handle 81 as follows. It has a simple configuration. As shown in FIG. 10, the cleaning nozzle 24a is usually located at an initial position inside the main body 22, and has a conduit 24b for guiding the cleaning water supplied from the tank. Therefore, when the cleaning water is jetted at the initial position, the jetted cleaning water rebounds on the cover portion 22a of the main body 22, and the self-cleaning of the cleaning nozzle 24a is performed by the repelled cleaning water. A rack 24c is formed on the cleaning nozzle 24a. The rotation of the pinion 82 meshing with the rack 24c causes the cleaning nozzle 24a to move from the initial position to the illustrated butt cleaning position 2.
4d or the bidet cleaning position 24e.

As shown in FIG. 11, a rotation shaft 83 fixed to the center of the pinion 82 extends to the inside of the operation section 26 and is engaged with the nozzle advance / retreat lever 80. The rotating shaft 83 is supported by a bearing (not shown), and is rotatable forward and backward about a central axis thereof. Therefore, when the nozzle advance / retreat lever 80 is rotated as shown by the arrow B in the figure, the pinion 82 rotates and the washing nozzle 24a advances to the buttocks washing position 24d. When the nozzle advance / retreat lever 80 is further rotated, the cleaning nozzle 24a is rotated.
Moves forward to the bidet cleaning position 24e. Then, when the nozzle advancing / retreating lever 80 is rotated in the reverse direction and returns to the original position, the cleaning nozzle 24a retreats to the initial position. In this case, as shown in FIG. 12, a notation indicating the operation position of the nozzle advance / retreat lever 80 is written on the surface of the operation unit 26,
If the nozzle advancing / retracting lever 80 is located at the position described as "self", the cleaning nozzle 24a is at the initial position and the "butt"
If the nozzle advancing / retreating lever 80 is located at the position indicated as "", the cleaning nozzle 24a is at the buttocks cleaning position 24d,
If the nozzle advancing / retracting lever 80 is located at the position described as "", the cleaning nozzle 24a is located at the bidet cleaning position 24e. When the nozzle advance / retreat lever 80 is “self”,
A moderation imparting mechanism that gives a so-called moderation feeling to the operator when operated to the notation position of “butt” or “bidet” is incorporated. Can be located.

The washing water ejection handle 81 is connected to a manual valve (not shown) that opens and closes a pipe that extends from a tank housed in the operation section 26 to the washing nozzle 24a. Then, the cleaning water ejection handle 81 is moved to the position shown in FIG.
The line is closed when it is at the “stop” position shown in FIG. 5, and is opened when it is rotated to the “spout” position. Therefore, by the rotation operation of the washing water ejection handle 81, the ejection of the washing water from the washing nozzle 24a is performed or stopped. It should be noted that the letters “Self”, “Ass”, “Bidet”, “Stop”, and “Squirt” indicating the operation positions of the nozzle advancing / retreating lever 80 and the washing water ejection handle 81 can be replaced with graphic symbols. It is.

Here, the state of local cleaning by the sanitary cleaning device 20A will be described. First, when the nozzle advance / retreat lever 80 is at the “self” position, the user rotates the washing water ejection handle 81 to the “spout” position. As a result, the cleaning nozzle 24a ejects the cleaning water at the initial position, and the self-cleaning of the nozzle is performed. Next, the user returns the washing water ejection handle 81 to the “stop” position to stop the ejection of the washing water from the nozzle. Thereafter, the nozzle advance / retreat lever 80 is operated to the "butt" or "bidet" position to move the washing nozzle 24a to the butt washing position 24d or the bidet washing position 24e. Then, the washing water jetting handle 81 is rotated again to the "spouting" position, and the washing water is jetted from the washing nozzle 24a at the buttocks washing position 24d or the bidet washing position 24e to perform local washing. After performing the local cleaning for a desired time, the return of the cleaning water ejection handle 81 to the “stop” position and the return of the cleaning water ejection handle 81 to the “self” position are sequentially performed in this order. Stop jetting and wash nozzle 24
a is returned to the initial position.

Even in the sanitary washing device 20A in which the washing water is jetted out only with water using the above-mentioned water supply pressure (tap water pressure) of the washing water, the main body 2 in the sanitary washing device 20A is used.
Assuming that the configuration of No. 2 is based on low tap water pressure (less than 0.1 MPa), in order to introduce such a low tap water pressure in an area such as Southeast Asia, the pipeline in the branch pipe 32 is required. The member 34 may be a conduit member 34 having a simple conduit as shown in FIG. On the other hand, in order to introduce the tap water pressure into an area where the tap water pressure is higher than the low tap water pressure, for example, Japan and European countries, a pipe member 34A having an orifice portion 34b as shown in FIG. 4 is used. May be an orifice portion 34b whose pipe area is adjusted so as to produce a pressure difference between the tap water pressure in the area and the low tap water pressure, and the pressure may be adjusted by the pressure loss at the orifice portion 34b. . Therefore, in areas where it is difficult to install a power supply around the toilet and it is not possible to warm the wash water, or in areas where it is not necessary to warm the wash water due to the warm climate, By adjusting the supply pressure of the washing water through the exchange of the 34 and 34A, the sanitary washing device 20A can be easily introduced.

Next, a modified example of the sanitary washing device 20A will be described. In this modification, a nozzle advance / retreat handle 85 is used instead of the nozzle advance / retreat lever 80. That is, FIG.
As shown in FIG. 3, in the sanitary washing device 20 </ b> A according to the modified example, the operation unit 26 is provided with a nozzle advance / retreat handle 85 that is rotated. As shown in FIG.
As shown in FIG. 7, a so-called flexible shaft 86 formed of a wire, a coil or the like is connected.
Is fixed to the rotating shaft 83. Therefore, when the nozzle advance / retreat handle 85 is rotated from the “self” position to the “butt” position or the “bidet” position as shown in FIG.
The rotation is transmitted to the pinion 82 via the flexible shaft 86 and the rotating shaft 83, and the washing nozzle 24a moves to the buttocks washing position 24d or the bidet washing position 24e. Then, by the rotation operation of the nozzle advance / retreat handle 85 and the above-described rotation operation of the cleaning water ejection handle 81, local cleaning is performed. Note that the nozzle advance / retreat handle 85 is
6 may be provided on the side surface of the operation unit 26 instead of the upper surface.

The embodiments of the present invention have been described above.
The present invention is not limited to these embodiments at all, and it is a matter of course that the present invention can be implemented in various modes without departing from the gist of the present invention.
