Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cleaning nozzle drive device used in a warm water-washing toilet seat. This invention relates to a technique for efficiently performing positioning at multiple positions and cleaning thereof.

[Prior Art] Conventionally, in a drive device for a cleaning nozzle of a warm water-washing toilet seat,
As shown in FIG. 12, cleaning water is force-fed into the syringe tube 7 of the syringe 3, the piston 28 is moved, and the nozzle rod 5 integrated with the piston 28 is made to protrude.
Cleaning water is then jetted through the water passage through hole 4 formed in the nozzle rod 5 and from the jet hole 16 of the cleaning nozzle 2 formed at the tip of the nozzle rod 5 to clean the private parts of the human body sitting on the toilet seat 1. It is something to do.

[Problem to be solved by the invention] However, in such a configuration, there is no ejection hole 1 at the tip.
The nozzle rod Y5 forming the nozzle rod 6 has two positions: a protruding position in which it protrudes from the syringe-tube 7 of the syringe 3, and a retired position in which the piston 28 and nozzle rod 5 are returned by the return spring 6 when water supply is stopped and no water supply pressure is applied. Because the protruding position of the nozzle rod 5 is different when performing anal cleaning and bidet cleaning, it is difficult to perform these cleanings with one shilling-3, and it is even more difficult to clean the anus and bidet due to the amount remaining in the nozzle rod 5 at the beginning of cleaning. There is a problem in that in order to discharge the cold water and perform comfortable washing, changes must be made in three stages, making the configuration complicated. Moreover,
The nozzle rod 5 in the cylinder tube 7 is made to protrude by force-feeding cleaning water, and then the nozzle rod 5 is pushed out by the return spring 6.
There is also the problem that the gasket P provided on the piston 28 is constantly in sliding contact with the inner surface of the shilling tube 7 in order to return the piston 28 to the retracted position, resulting in severe wear of the gasket P.

The present invention was made in view of such problems,
Its purpose is to make multiple #r with one shilling.
It is possible to select the length of the bulge over the floor, simplify the configuration and control system, and in particular avoid wear of the seal provided on the piston, while still maintaining watertightness in the cleaning position when the piston is stopped. With sufficient consideration,
It is an object of the present invention to provide a drive structure for a washing nozzle of a warm water-washing toilet seat that can perform good washing.

[Means for Solving the Problems] The driving structure of the cleaning nozzle of the warm water-washing toilet seat of the present invention includes a cylinder 3 which expands in response to supply of cleaning water from the water supply means.
A nozzle rod 5 is connected to a piston 28 in a cylinder tube 7, a through hole 4 for passing cleaning water is formed inside the nozzle rod 5, an ejection hole 16 is formed at the tip of the nozzle rod 5, and a screw ( A return spring 6 is provided to urge the cylinder 28 toward the return side, and a locking means is provided to prevent expansion of the cylinder 3 due to the water supply pressure of washing water and change the extension length of the cylinder 3 in a plurality of stages. A driving device for a washing nozzle of a warm water-washing toilet seat, which extends a shilling-3 to a desired position in response to a supply of washing water from a water supply means and sprays washing water to a private part of a human body sitting on a toilet seat 1 at a desired position. There it is,
On the inner surface of the cylinder tube 7,
It is characterized in that a circumferential protrusion 7a is formed at a position corresponding to a plurality of locking positions, with which a seal P provided on the piston 28 comes into elastic, watertight contact over the entire circumference.

Further, one of the plurality of extension positions of the syringe 3 is a residual water removal position for draining residual water in the nozzle rod 5, and it is noted that the circumferential protrusion 7a is not formed in this residual water removal position. This is a characteristic feature.

Further, the cylinder tube 7 is characterized in that a gasket Q is provided at the inner end of the cylinder tube 7 so that the end surface of the piston 28 comes into elastic contact with the cylinder at the maximum extension position of the above-mentioned Schilling-3 to ensure positioning at the maximum extension position and watertightness. .

[Function] In this way, the nozzle rod 5 is connected to the piston 28 in the cylinder tube 7 of the Schilling-3, which expands upon receiving the supply of cleaning water from the water supply means, and the cleaning water is passed through the inside of the nozzle rod 5. A through hole 4 is formed, a jet hole 16 is formed at the tip of the nozzle rod 5, and a return spring 6 is provided to urge the piston 28 to the return side, so that the expansion of the sill-3 due to the water supply pressure of the cleaning water is prevented. By being provided with a locking means that prevents the extension length of the Schilling-3 from changing in multiple stages, the extended length of the Schilling-3 can be set over multiple stages, and one Schilling-3 can set the extended length of the Schilling-3 in multiple stages. While its extension length can be changed, for example anal cleaning,
Multi-step movements such as bidet cleaning and cold water discharge can be performed with a single shilling-3, the entire structure is made into a cylinder, and the extension length of the shilling-3 can be easily controlled to change in multiple stages. In particular, the circumference is such that the seal P provided on the piston 28 is in elastic contact with the piston 28 in a water-tight manner at locations corresponding to the plurality of locking positions of the nozzle rod 5 on the inner surface of the syringe tube 7. By forming the protrusion 7a, the seal P provided on the piston 28 comes into strong elastic contact only with the circumferential protrusion 7a during expansion and contraction.
This prevents the packing P from coming into strong sliding contact with the inner surface of the cylinder tube 7 over the entire length, thereby avoiding wear of the packing P, and at the same time, the packing P is moved to the circumferential protrusion 7a on the inner surface of the cylinder tube 7 at its stop position i. The seal P of the piston 28 is in elastic contact with the cylinder tube 7 to ensure sufficient watertightness and to perform individual local cleaning well, and the seal P of the piston 28 is in soft contact with the inner peripheral surface of the cylinder tube 7 at locations other than the circumferential protrusion 7a. This allows the piston 28 to move smoothly.

Further, one of the plurality of extension positions of the sill-3 is a residual water removal position for draining residual water in the nozzle rod 5, and the circumferential protrusion 7a is not formed in this residual water removal position. By removing the residual water in the nozzle rod 5, the discomfort during private part cleaning is eliminated, and at the position where the residual water is removed, there is no circumferential protrusion 7a and the gasket P and the circumferential protrusion 7a are separated. Residual water is not trapped in the silling tube 7 due to the elastic contact, and no residual water is generated. This also prevents severe wear.

In addition, by providing a gasket Q at the inner tip of the Schilling tube 7, which makes elastic contact with the tip end surface of the piston 28 at the maximum extension position of the Schilling-3 to ensure positioning and watertightness at the maximum extension position, the Schilling-3 is at its maximum extended position. The positioning and watertightness in such cases are designed to ensure good cleaning at the appropriate location.

Then, the piston 28 is driven and moved by the water pressure of the cleaning (warm) water supplied into the syringe-3, and the piston 28 is made to protrude from the shilling-tube 7 of the shilling-3, and the water accumulated in the cleaning nozzle 2 is first moved. The cold water is discharged and the supplied warm water is spouted toward the anus for anal cleansing, or the woman's private parts are sprayed for bidet cleansing, which can be selectively performed. The configuration will be explained in detail below.

FIG. 9 shows an exploded perspective view of the holding portion of the guide pin 8, in which an abbreviated holding hole 31 is formed in the holding plate 30, and a spring holding hole 32 is formed in communication with this holding hole 31. ing. The guide pin 8 is formed by bending a plate material, and the L-shaped piece 33 on one end side is loosely inserted into the L-shaped holding hole 31, and the spring 29 wound in a coil shape in the spring holding hole 32 is loosely inserted. Insert the spring 291 into the iron guide pin 8 in the direction of arrow A in Figure 9! I'm working hard. A protrusion 34 serving as a pin is formed at the tip of the guide pin 8. Thus, the spring 29 biases the protrusion 34 of the guide pin 8 to swing in a direction substantially perpendicular to the nozzle rod 5. The nozzle rod 5 is formed into a rectangular shape, and a guide groove 9 is formed on one side of the rectangular shape. The guide groove 9 is connected to the guide groove 9 at three locations on the side where the guide pin 8 is biased to swing, and locking portions 10 are formed therein. Among the three locking portions 10...from the tip side of the nozzle rod 5 toward the piston 28 side, there is a locking portion 10a for cold water discharge, a locking portion 10b for anal cleaning, and a locking portion 10b for cleaning the anus, and from the piston 28. A locking portion 10c for bidet cleaning is formed. Locking portions 10a+10b, 1 of guide groove 9
A return path 35 is formed on the tip end side of the nozzle rod 5 on the opposite side from 0c, and communicates with this return path 35.
A bidet guide path 36 is formed in a straight line, and an anus selection path 37 is formed at the end of the bidet guide path 36 for moving on to anal cleaning after bidet cleaning. or,
In the guide groove 9, a receiving piece 38 for initial position setting is formed on the nozzle rod 5 side. and piston 28
is biased toward the return side by a return spring 6.

Various cleaning operations will be explained in the above configuration.

When the push button 20 for the anal cleansing mode is pressed, the mode will change according to the mode set in the power supply drive circuit section 22 [MfJa figure (
b) 1, the motor 23 is driven intermittently. When the motor 23 is first driven, cleaning water is supplied into the cylinder 3, and the water pressure pushes the piston 28, causing the 1#
7. Push out the piston 28 at the return position shown in FIG.
The protrusion 34 of the guide pin 8, which is in elastic contact with the receiving piece 38 via the spring 29, is separated from the receiving piece 38, and the protrusion 34 of the guide pin 8 is locked in the locking part 10a [FIG. 7(d)
Reference 1, such locking prevents the piston 28 from protruding further, and in this inhibited state, hot water is supplied into the piston 28 and pushed out into the nozzle rod 5. The accumulated cold water is discharged outside the cleaning nozzle 2. If the nozzle rod 5 extends only slightly, the cold water discharged in this way will be directed toward the toilet seat 1, for example.
The cleaning nozzle 2 should be driven according to the primary mode so that it does not hit the bottom surface of the body and make the human body feel cold. Once the driving of the motor 23 is stopped, the water pressure decreases and the piston 28 is returned by the return spring 6, and although the piston 28 is biased by the spring 29, the protrusion 34 of the idle pin 8 is pushed back into the idle groove 9. Locking part 10a for cold water spout
As the piston 28 returns, the guide pin 8 is slid along the guide groove 9 toward the anus cleaning locking part 10b, and the protrusion 34 of the guide pin 8 moves to the anus cleaning locking part 10b. 10b to stop the return of the piston 28. In this way, as the return movement of the piston 28 stops, the motor 23 is driven again, and hot water is again supplied into the cylinder 3, passing through the water passage through hole 4 of the nozzle rod 5 to the tip of the nozzle rod 5. The water is ejected from the cleaning nozzle 2 toward the anus to clean the anus as prescribed. When the anal cleaning for the set time is finished, motor 2
3 is stopped and the water pressure applied to the piston 28 disappears, the return spring 6 returns the piston 28. In this return process, the protrusion 34 of the guide pin 8 is slid along the guide groove 9 that is in a straight line with the locking part 10b for anal cleansing, and the protrusion 34 of the guide pin 8 is moved along the guide groove 9 that is in a straight line with the locking part 10b for anal cleaning. It is returned to the tip side.

In such a case, a diagonal m39 is formed in the middle of the id groove 9, and a step is formed at the starting end of this slanted groove 39 and at the terminal end of the id groove 9 portion that faces the return path 35. 40 is formed, and at this step 40, the protrusion 34 of the guide bin 8 is prevented from moving in a straight line, and the guide bin 8 is
The rod advances diagonally along the diagonal groove 39, passes through the return path 35, reaches the tip of the nozzle rod 5, and is rocked and biased by the spring 29, but the protrusion 34 of the id pin 8 comes into contact with the receiving piece 38. to return to the initial position.

A valve body 14 is disposed at the end of the cylinder 3 on the hot water supply side, and when the piston 28 returns, the cylinder 3
This allows the remaining water inside to be quickly drained, allowing the piston 28 to return smoothly. In other words, piston 2
A lid-shaped body 41 is attached to the hot water supply side of the valve 8, a water supply port 12 and a drain port 13 are formed in this lid-shaped body 41, and a valve body 14 is disposed within this lid-shaped body 41 by being biased back with a spring 15. Then, the water supply force from the water supply means pushes the valve body 14 against the spring 15 to open the water supply port 12 and close the drain port 13, and when the water supply pressure disappears, the valve body 14 is returned by the spring 15. Water supply port 12
is closed and the drain port 13 is opened (so that the water supply to the cylinder 3 is stopped and the piston 28 and /X'' rod 5 are returned by the spring force of the spring 6.
When the water supply is stopped, the valve body 14 is returned by the spring 15 and the drain port 13 is opened, so that water can be drained quickly when the cylinder 3 is contracted, and the cylinder 3 can be easily contracted. Control for changing the length of the cylinder 3 can be easily performed.

Next, when you press the bidet cleaning mode push button 20, the motor 2
3 is intermittently driven in a pattern as shown in FIG. 8(d). When the motor 23 is first driven, cold water is drained in the initial stage, similar to the above-mentioned anal cleansing. When the motor 23 stops and the water pressure disappears, the piston 28 is returned by the return spring 6, and the guide bin 8 is slid along the guide groove 9, and the guide bin 8 is moved to the step. 40, the starting end of the diagonal groove 39, and the motor 23 is driven again in synchronization with the timing when the water reaches the locking part 10b for anal cleaning.
The piston 28 is pushed against the return spring 6, and as the piston 28 moves, the protrusion 34 of the guide pin 8
The id pin 8 is located at the step 40 at the starting end of the diagonal groove 39.
prevents the protrusion 34 from returning to a straight line, guides the guide bin 8 along the diagonal groove 39 in a kasuri pattern, and then returns to the return path 3.
5, the motor 23 is turned on again at the same time.
is driven, the piston 28 is pushed out, and the protrusion 34 of the guide bin 8 is guided through the bidet guide path 36 and the anus selection path 37 to the bidet locking part 10c. By locking the protrusion 34 of the guide bin 8, the cleaning nozzle 2 at the tip of the nozzle rod 5 is positioned at the bidet position, and with the subsequent drive of the motor 23, cleaning water is ejected from the cleaning nozzle 2 to clean the bidet. Do it. In such a case, the depth of the diagonal groove 39 is equal to the return path 35.
It becomes shallower as it approaches the side, and the height of the end of the diagonal groove 39 is higher than the depth of the return path 35. In other words, a step 42 is formed at the end of the diagonal groove 39, and the height of the end of the diagonal groove 39 is higher than the depth of the return path 35. This is to prevent the protrusion 34 from entering the diagonal groove 39 side from the return path 35.

When the bidet cleaning ends, the motor 23 is stopped, and the piston 28 goes through the same process as the anal cleaning described above, and the protrusion 34 of the guide bin 8 returns to the tip of the nozzle rod 5, returning to the initial position. .

Next, when the push button 20 for the anal cleaning/bidet cleaning mode is pressed, the motor 23 is driven intermittently according to the mode set in the power supply drive circuit section 22 (FIG. 8(f) 1). When the motor 23 is first driven, cold water is drained at the initial stage, similar to the anal cleaning and bidet cleaning described above. Anal cleansing is then performed in the same manner as the anal cleansing described above. Then, while the motor 23 is stopped at the timing when the anal cleaning ends [! #8 Indicated by the symbol T in FIG. hits the step 40 at the starting end of the diagonal rR39, the guide pin 8 advances obliquely along the diagonal groove 39, and the motor 23 is driven again in time with the timing of passing through the return path 35, the piston 28 is pushed out, and the guide pin 8 is pushed out. The protrusion 34 of the pin 8 is the guide path 36 for the bidet.
, is guided to the bidet locking part 10c through the anus selection path 37, and the protrusion 34 of the guide pin 8 is locked to the bidet locking part 10e, so that the cleaning nozzle at the tip of the nozzle rod 5 is guided to the bidet locking part 10c. 2 to the bidet position, and the following motor 23
The bidet cleaning is performed as described above by ejecting cleaning water from the cleaning nozzle 2 by driving. Then, at the timing when the bidet cleaning ends, the motor 23 is stopped, and the guide pin 8 returns to the initial position through the same process as the bidet cleaning.

By the way, in the steps shown in FIGS. 8(e) and (f),
Although the bidet cleaning is performed after the anal cleaning is completed, the anal cleaning may be performed after the bidet cleaning is completed.

At the tip of the cleaning nozzle 2, a sonic type fluid element/fnir 46 is constructed, and by pulsating the jet direction of the cleaning water in the small medium, a mild movement cleaning feeling is achieved. It's Nishide.

In the above configuration, the present invention provides the Schilling-tube 7
A circumferential protrusion with which an O-ring-shaped gasket P provided on the piston 28 is in elastic contact with watertight over the entire circumference at positions corresponding to the two stopping positions of the nozzle rod 5 at the anus cleaning position and the bidet cleaning position on the inner surface of the piston 28. 7a is formed.

In this way, the seal P provided on the piston 28 comes into strong (elastic) contact with the circumferential protrusion 7a when it expands and contracts. At the same time, at its stop position, the packing P makes strong elastic contact with the circumferential protrusion 7a on the inner surface of the silling tube 7, ensuring sufficient watertightness, and sealing the individual parts without causing water leakage. The private parts can be cleaned well. In other words, the anus and bidet can be cleaned well.Furthermore, the gasket P provided on the piston 28 is in strong elastic contact with the circumferential protrusion 7a at its stop position, and both In the recess between the circumferential protrusions 7a and ?a, the gasket P makes relatively soft sliding contact with the inner circumferential surface of the sill-tube 7, which allows the piston 28 to move smoothly, and the nozzle The travel time of the rod 5 can be shortened.In other words, in the concave portions of both circumferential protrusions 7JL and 7a of the sill-tube 7, the gasket P of the piston 28 comes into contact relatively softly and resists the return spring 6. It is only necessary to generate enough pressure to cause the piston 28 to protrude.

During cleaning 1, the circumferential protrusion 7a is not formed at the residual water removal position, and the gasket P and the circumferential protrusion 7 are not formed at the residual water removal position.
Residual water is not contained in the cylinder tube 7 due to elastic contact with a, and no residual water is generated (also, sliding contact between the seal P and the circumferential protrusion flfs 7 a is avoided, and the seal Unnecessary wear of P is also avoided.

FIG. 11 shows another embodiment, in which the end face of the piston 28 comes into elastic contact with the cylinder tube 7 in the maximum extension position of the Schilling-3, and the seal Q is positioned in the maximum extension position and watertight. It is provided at the inner tip of the syringe 3 to position it at its maximum extension position and to ensure watertightness in such a case, allowing for good cleaning at the appropriate position.

In the embodiment, the guide pin 8 was provided on the cylinder tube 7 side and the guide groove 9 was formed on the nozzle rod 5 side, but the guide pin 8 was provided on the cylinder tube 7gA and the guide pin 8 was provided on the cylinder tube 7gA. It may be formed.

In addition, in the embodiment, the guide pin 8 is connected to the spring 29.
Although the guide bin 8 was biased to swing in a certain direction, the guide bin 8 was not biased by the spring 29, and the guide bin 8 was attached to the locking portion 10 of the guide groove 9 by setting the shape of the guide groove 9. It may be configured so that it is guided. The formation of the guide groove 9 can be modified in various ways.

Further, in the embodiment, the locking portions 10 are set at three locations, but the number may be greater or less than this.

Further, in the embodiment, the motor 23 is driven to force-feed the wash water, but tap water may be force-fed by opening and closing a valve.

Furthermore, although hot water cleaning is performed in the embodiment, cleaning may be performed using low temperature cleaning water.

[Effects of the Invention] In summary, the present invention has a nozzle rod connected to a piston in a cylinder tube of a cylinder that expands in response to supply of cleaning water from a water supply means, and a through hole for passing cleaning water inside the nozzle rod. A hole is formed, an ejection hole is formed at the tip of the nozzle rod, and a return spring is provided that biases the piston toward the return side, thereby preventing the cylinder from expanding due to the water supply pressure of the cleaning water and reducing the cylinder's extended length. Since it is equipped with a locking means that changes the setting in multiple stages, the extension length of the cylinder can be set in multiple stages, and the extension length can be changed even though it is one cylinder. Multi-step operations such as washing, bidet washing, and cold water discharge can be performed with a single cylinder, simplifying the overall configuration, and easily controlling the extension length of the cylinder to be changed in multiple steps. In particular, a circumferential protrusion is formed on the inner surface of the cylinder tube that corresponds to the plurality of locking positions of the nozzle loft, and the seal provided on the piston makes elastic contact with the piston in a water-tight manner over the entire circumference. It is only necessary for the seal provided in the seal to come into strong elastic contact with only the circumferential protrusion when it expands and contracts, and the seal should be in strong (sliding) contact with the inner surface of the entire length of the syringe tube, thereby avoiding wear of the seal, and at the same time preventing the seal from stopping. At the position, the gasket elastically contacts the circumferential protrusion on the inner surface of the cylinder tube to ensure sufficient watertightness and allows for individual local cleaning. This has the advantage that it makes soft contact with the piston, allows smooth movement of the piston, and allows the movement of the piston, that is, the nozzle rod, to be carried out in a short period of time.

In addition, one of the plurality of extension positions of the cylinder is a residual water removal position for draining the residual water in the nozzle rod, and since the circumferential protrusion is not formed at this residual water removal position, the inside of the nozzle rod is By removing the residual water, you can eliminate discomfort when cleaning your private parts, and at the position where the residual water is removed, there is no circumferential protrusion, and the elastic contact between the seal and the circumferential protrusion allows the inside of the syringe tube to be removed. This has the advantage that residual water is not trapped (and no residual water is generated), and sliding contact between the packing and the circumferential protrusion can be avoided, and unnecessary wear of the packing can also be avoided.

In addition, a gasket is provided at the inner end of the cylinder tube so that the end surface of the piston comes into elastic contact with the cylinder at its maximum extension position to ensure positioning at the maximum extension position and watertightness.
This has the advantage that it is possible to position the cylinder at its maximum extension position and to ensure watertightness in case of breakage, and to perform good cleaning at the appropriate position.
