  The T-shaped tube 14 is a pipe member having one inlet 14c and two outlets 14a and 14b, and the inlet 14c is connected to a single water supply source S. One outlet 14a is connected to the box rim 2b of the main body 2 through the dirty water distribution via the flush water discharge opening / closing valve 16 and the flush water discharge line 4b. The other outlet 14b communicates with the cleaning water discharge port 4a via the constant flow valve 20 and the cleaning water discharge opening / closing valve 18.

  The flush water discharge opening / closing valve 16 is an electromagnetic valve that is opened and closed by a signal from the controller 22, and is disposed between the outlet 14 a of the T-shaped tube 14 and the flash water discharge pipe 4 b. When the flush water discharge opening / closing valve 16 is opened, a large amount of flush water is discharged from the box rim 2b. In the present embodiment, as the flush water discharge, cleaning water of about 100 liters / minute is discharged for about 10 seconds at an instantaneous maximum flow rate.

  The cleaning water discharge opening / closing valve 18 is an electromagnetic valve that is opened and closed by a signal from the controller 22, and is disposed between the constant flow valve 20 and the cleaning water discharge port 4a. When the cleaning water discharge opening / closing valve 18 is opened, the dirty water is discharged from the cleaning water discharge port 4a positioned above the bowl portion 2a of the main body 2 by the dirty flow.

  The constant flow valve 20 is disposed between the outlet 14b of the T-tube 14 and the cleaning water discharge opening / closing valve 18, and restricts the flow rate of the cleaning water flowing into the cleaning water discharge opening / closing valve 18 to a predetermined flow rate or less. Is configured to do. In the present embodiment, the constant flow valve 20 is configured to limit the flow rate of cleaning water flowing into the cleaning water discharge opening / closing valve 18 to about 15 liters / minute or less. The structure of the constant flow valve 20 will be described later.

  When the controller 22 receives a signal from the flash foot switch 6 or the flash switch 10, the controller 22 is configured to open the flash water discharge on / off valve 16 for about 4 seconds and then close it to perform one flash water discharge. . Further, when the controller 22 receives a signal from the cleaning foot switch 8 or the cleaning switch 12, the controller 22 opens the cleaning water discharge opening / closing valve 18, and when the controller 22 receives a signal from the cleaning foot switch 8 or the cleaning switch 12 again, the controller 22 The on-off valve 18 is configured to be closed.

  Furthermore, the controller 22 is configured to automatically perform flush water discharge when a predetermined condition is satisfied. Specifically, it is constituted by a microprocessor, a memory, and a program (not shown above) for operating these. Details of the control by the controller 22 will be described later.

  The generator 23 is provided in a water supply pipe line between the water supply source S and the inlet 14 c of the T-shaped pipe 14. The generator 23 includes an impeller (not shown) disposed in the water supply pipe line. When the impeller is flushed or discharged, the water flow is rotated by the water flowing through the water supply pipe line. The The rotation of the impeller is converted into electrical energy and sent to the controller 22. The controller 22 charges this electrical energy and is activated by the charged electrical energy.

Next, with reference to FIG. 3, the structure of the constant flow valve 20 which is a flow volume adjustment means is demonstrated.
As shown in FIG. 3, in the present embodiment, the constant flow valve 20 forms an assembly that is integral with the check valve 24 provided adjacent thereto.
The constant flow valve 20 includes a constant flow valve body 26, a constant flow valve body 28 that is slidably disposed within the constant flow valve body 26, and a constant flow valve that urges the constant flow valve body 28 in the opening direction. A flow valve spring 30.

  The constant flow valve main body 26 is a substantially cylindrical member, and a constant flow valve body 28 is slidably held on the central axis of the constant flow valve main body 26. In addition, a metal mesh is disposed on the side surface of the constant flow valve main body 26 to rectify the cleaning water flowing into the constant flow valve main body 26 and prevent dust from entering the inside.

  The constant flow valve body 28 is configured to be slid by the flow of cleaning water flowing into the constant flow valve body 26. The constant flow valve spring 30 is a coil spring wound in a conical shape and urges the constant flow valve body 28 in a direction in which the constant flow valve body 28 is opened. When the flow rate passing through the constant flow valve body 26 becomes larger than the predetermined flow rate, the constant flow valve body 28 is slid against the urging force of the constant flow valve spring 30, and the opening degree of the constant flow valve 20 is reduced. On the contrary, when the flow rate passing through the constant flow valve body 26 is small, the constant flow valve body 28 is slid by the urging force of the constant flow valve spring 30, and the opening degree of the constant flow valve 20 is increased. Thereby, the flow volume which passes through the constant flow valve 20 is maintained substantially constant.

  The check valve 24 urges the check valve body 32, a check valve body 34 slidably disposed with respect to the check valve body 32, and a direction in which the check valve body 34 is closed. And a check valve spring 36.

  When the pressure on the downstream side of the check valve 24 becomes lower than the pressure on the upstream side, the check valve body 34 is slid against the urging force of the check valve spring 36 and opened. On the contrary, when the upstream pressure becomes lower than the downstream pressure, the check valve body 34 is closed by the urging force of the check valve spring 36, and the backflow of the washing water is prevented.

  As shown in FIG. 3, the wash water flowing in from the inlet 24 a of the assembly of the constant flow valve 20 and the check valve 24 slides the check valve body 34 against the urging force of the check valve spring 36 due to water. And pass through the check valve 24. The wash water that has passed through the check valve 24 flows into the constant flow valve body 26 and passes through the constant flow valve 20. Wash water that has passed through the constant flow valve 20 flows out from the outlet 20a of the assembly. Further, when the flow rate of the washing water to pass through the constant flow valve 20 increases, the constant flow valve body 28 slides against the urging force of the constant flow valve spring 30 and the opening degree of the constant flow valve 20 decreases. To do. On the other hand, when the flow rate of the washing water that is going to pass through the constant flow valve 20 decreases, the constant flow valve body 28 is slid by the urging force of the constant flow valve spring 30 and the opening degree of the constant flow valve 20 increases. Thereby, the flow rate of the washing water passing through the constant flow valve 20 is maintained substantially constant.

Next, the operation of the filth logistics 1 according to the first embodiment of the present invention will be described.
First, with reference to FIG. 4 newly, water discharge by a user's manual is demonstrated. FIG. 4 shows, in order from the top, a signal issued from the cleaning foot switch 8, a state of the cleaning water discharge on / off valve 18, a signal generated from the flush foot switch 6, and a state of the flush water discharging on / off valve 16 in time series. It is a graph.

  First, the user of the filth distribution 1 disposes the filth contained in the urine bottle or the like into the bowl portion 2a of the main body 2 and disposes it. Next, when the user steps on the cleaning foot switch 8 at time t1 in FIG. 4, the cleaning foot switch 8 transmits a radio wave, and the controller 22 receives the radio wave. When the controller 22 receives a signal from the cleaning foot switch 8 in a state where the cleaning water discharge opening / closing valve 18 is closed, the controller 22 sends a signal to the cleaning water discharge opening / closing valve 18 to open it. When the cleaning water discharge opening / closing valve 18 is opened, the cleaning water supplied from the water supply source S passes through the inlet 14 c, the outlet 14 b, the constant flow valve 20, and the cleaning water discharge opening / closing valve 18 of the T-tube 14. It is discharged from the cleaning water outlet 4a and flows down to the bowl portion 2a.

  Here, the water supply source S is a water supply source capable of supplying a large flow rate that can also be used for flush water discharge, but the wash water flowing out from the outlet 14b of the T-shaped tube 14 has a flow rate at the constant flow valve 20. The flow rate is restricted, and the flow rate is suitable for cleaning of a urine bottle or the like and discharged from the cleaning water outlet 4a. The user cleans the urine bottle or the like with the cleaning water discharged from the cleaning water outlet 4a.

  Next, when the user steps on the flash foot switch 6 at time t2, the flash foot switch 6 transmits a radio wave, and the controller 22 receives it. When the controller 22 receives the signal from the flash foot switch 6, it sends a signal to the flash water discharge on / off valve 16 to open it for a predetermined time (until time t 3). In the present embodiment, the flush water discharge on-off valve 16 is opened for about 4 seconds. When the flush water discharge opening / closing valve 16 is opened, the wash water supplied from the water supply source S passes through the inlet 14c, the outlet 14a, the flush water discharge opening / closing valve 16, and the flush water discharge pipe 4b of the T-shaped tube 14. Then, the water is discharged from the water outlet of the box rim 2b provided in the bowl portion 2a and flows into the bowl portion 2a.

  Since the flush water discharge causes a large amount of washing water to flow into the bowl portion 2a, the water level in the bowl portion 2a rises rapidly, and the filth and washing water accumulated in the bowl portion 2a are discharged into the drain trap pipe 2c. It gets over to the sewer pipe.

  When the flush water discharge opening / closing valve 16 is opened, the washing water supplied from the water supply source S flows to the box rim 2b in addition to the washing water discharge port 4a. The pressure of the washing water flowing into the water drops rapidly. Even in such a state where the pressure is reduced, the water supply pressure necessary for discharging the cleaning water at an appropriate flow rate from the cleaning water outlet 4a is maintained. For this reason, the water discharge flow rate from the cleaning water discharge port 4a is maintained substantially constant even after the flush water discharge is started.

  Next, when the flush water discharge opening / closing valve 16 is closed at time t3, the wash water from the water supply source S does not flow toward the box rim 2b, so the pressure of the wash water flowing into the constant flow valve 20 is It rises rapidly. Thus, when the feed water pressure flowing into the constant flow valve 20 increases, the constant flow valve body 28 (FIG. 3) of the constant flow valve 20 is slid in the closing direction (downward in FIG. 3), and the constant flow valve 20 is moved. The flow rate passing through is maintained almost constant. Thereby, when the flush water discharge opening / closing valve 16 is closed, it is possible to prevent the water discharge flow rate from the cleaning water discharge port 4a from rising unexpectedly and causing a large water splash at the time of cleaning the urine bottle or the like.

When the user steps on the cleaning foot switch 8 again at time t4 after the cleaning of the urine bottle or the like is completed, the cleaning foot switch 8 transmits a radio wave, and the controller 22 receives it. When the controller 22 receives a signal from the cleaning foot switch 8 in a state in which the cleaning water discharge opening / closing valve 18 is opened, the controller 22 sends a signal to the cleaning water discharge opening / closing valve 18 to close it. Thereby, the water discharge from the cleaning water outlet 4a is stopped.
Finally, at time t5, the user steps on the flush foot switch 6 again, performs flush water discharge from the box rim 2b, and cleans the bowl portion 2a.

  In the above operation, the user has exclusively operated the flash foot switch 6 and the cleaning foot switch 8. However, if the user holds his / her finger over the flash switch 10 and the cleaning switch 12, the filth is exactly the same. A sink 1 can be used.

  Next, automatic flush water discharge executed by the controller 22 will be described with reference to FIG. FIG. 5 shows, in order from the top, a signal issued from the cleaning foot switch 8, a state of the cleaning water discharge on / off valve 18, a signal generated from the flush foot switch 6, and a state of the flush water discharging on / off valve 16 in time series. It is a graph.

  First, at time t1 in FIG. 5, the user operates the cleaning foot switch 8 to discharge water from the cleaning water outlet 4a, and starts cleaning the urine bottle and the like. If neither the flash foot switch 6 nor the flash switch 10 is operated for a predetermined initial flush water discharge time T1 after the cleaning starts at the time t1, the controller 22 automatically opens and closes the flush water discharge. A signal is sent to the valve 16 to perform flush water discharge once. This is because, at the start of washing at time t1, it is assumed that the filth in the urine bottle or the like is discarded in the bowl portion 2a, and the state in which the filth is discarded in the bowl portion 2a is maintained for a long time. This is to prevent the generation of odor. In the present embodiment, the initial flush water discharge time T1 is set to about 30 seconds. Preferably, the initial flush water discharge time T1 is set to about 10 seconds to about 50 seconds.

  Furthermore, after flush water is automatically discharged at time t2, during the cleaning, when neither the flash foot switch 6 nor the flash switch 10 is operated for a predetermined flush water discharge interval time T2, the controller 22 A signal is automatically sent to the flush water discharge on-off valve 16 to perform flush water discharge once. This is because a certain amount of time has passed after the flush water discharge at time t2, and it is assumed that the filth washed away from the urine bottle or the like has accumulated in the bowl portion 2a, and this state is prevented from continuing. . Further, when neither the flash foot switch 6 nor the flash switch 10 is operated, the controller 22 automatically executes flash water discharge once every flash water discharge interval time T2.

  In the present embodiment, the flush water discharge interval time T2 is set to about 2 minutes. Preferably, the flush water discharge interval time T2 is set to about 1 minute to about 3 minutes. Here, the flush water discharge interval time T2 is set to be longer than the initial flush water discharge time T1. In the initial stage of cleaning, a large amount of filth contained in the urine bottle or the like is discarded in the bowl portion 2a. This is because it is assumed that the amount of filth collected in the bowl portion 2a is relatively small after the flush water discharge is executed once.

  Next, at time t5, the user operates the cleaning foot switch 8 to stop water discharge from the cleaning water outlet 4a, and finishes cleaning the urine bottle and the like. When the flush foot switch 6 and the flush switch 10 are not operated for a predetermined automatic flush water discharge time T3 after the end of the cleaning at the time t5, the controller 22 automatically sends a signal to the flush water discharge on / off valve 16. And flush one time. This is because it is assumed that the user forgot to wash the bowl portion 2a by flushing the water after the washing at time t5. In the present embodiment, the automatic flush water discharge time T3 is set to about 5 minutes. Preferably, the automatic flush water discharge time T3 is set to about 4 minutes to about 6 minutes.

If the cleaning water discharge is resumed within the predetermined cleaning continuation waiting time T0 after the cleaning water discharge is stopped, the controller 22 determines that the cleaning operation by the user is continuing, The automatic flush water discharge based on the flush water discharge time T1 is canceled, and after the cleaning water discharge is resumed, the flush water discharge every flash water discharge interval time T2 is continued. In addition, when the cleaning water discharge is stopped and the cleaning water discharge is started after a predetermined cleaning continuation waiting time T0 has elapsed, the controller 22 indicates that another user has started cleaning another urine bottle or the like. to decide. In this case, the controller 22 automatically executes flush water discharge when the initial flush water discharge time T1 has elapsed after the start of cleaning water discharge.
In the present embodiment, the cleaning continuation waiting time T0 is set to about 10 minutes. Preferably, the cleaning continuation waiting time T0 is set to about 5 minutes to about 15 minutes.

  Further, when the controller 22 determines that neither flush water discharge nor cleaning water discharge has been performed even after a predetermined facility protection cleaning time has elapsed since the last flush water discharge or cleaning water discharge, the odor due to the drain trap running out of water is removed. In order to suppress, flush water automatically. In this embodiment, the equipment protection cleaning time is set to about 1 day. Preferably, the equipment protection cleaning time is set to about 0.5 to about 2 days.

  According to the filth distribution of the first embodiment of the present invention, since the fluctuation of the water discharge flow rate from the cleaning water discharge port is suppressed by the constant flow valve, the flush water discharge and the cleaning water discharge are supplied from a single water supply source. However, the flow rate of the cleaning water discharge does not change abruptly. Thereby, it is possible to easily increase the existing flush toilet or to improve the usability of the filth washing apparatus while enabling easy installation in a place where the flush toilet is installed.

  Further, according to the filthy logistics of this embodiment, after the flush water discharge opening / closing valve is closed, the flush water discharge is automatically performed when the flash water discharge operation unit is not operated for the automatic flush water discharge time. Since it is executed, it is possible to prevent forgetting to flush the water discharged after completion of the cleaning operation.

  Further, according to the filthy logistics of this embodiment, if the flush water discharge operation unit is not operated for the initial flush water discharge time after the cleaning water discharge opening / closing valve is opened, the flush water discharge is automatically performed. Since it is executed, it is possible to prevent a state in which a large amount of filth is accumulated in the bowl portion of the filth distribution from being left for a long time in the initial stage of cleaning. Thereby, generation | occurrence | production of the odor etc. from dirty distribution can be suppressed.

  Further, according to the filthy logistics of the present embodiment, when the flush water discharge operation unit is not operated after the initial flush water discharge time has elapsed and the flush water discharge operation unit is not operated, Since the flush water discharge is automatically executed at every interval time, the filth can be discharged before a large amount of filth accumulates in the bowl portion of the filth distribution.

  Furthermore, according to the waste logistics of the present embodiment, the controller is operated by the electric power generated by the generator, so the waste washing apparatus can be installed in a place where a commercial power source for operating the waste washing apparatus is not laid. Can be installed.

  In the first embodiment described above, the constant flow valve is used as the flow rate adjusting means. However, the pressure reducing valve can be used as the flow rate adjusting means instead of the constant flow valve.

  Further, in the first embodiment described above, after the start of the cleaning, after the predetermined initial flush water discharge time T1 has elapsed, the controller automatically performs the flash water discharge once and then every predetermined flash water discharge interval time T2. Is configured to perform flushing water discharge. However, the initial flush water discharge time T1 and the flash water discharge interval time T2 can be arbitrarily set. For example, as a modification, the present invention can be configured such that flush water discharge is performed every predetermined flash water discharge interval time T2 immediately after the start of cleaning.

  Next, with reference to FIG. 6, the filth distribution according to the second embodiment of the present invention will be described. The dirty logistics of this embodiment differs from the first embodiment described above in the configuration of the flow rate adjusting means. Accordingly, here, only the points of the second embodiment of the present invention that are different from the first embodiment will be described, and description of similar configurations will be omitted. FIG. 6 is a block diagram showing a dirty water supply system according to the second embodiment of the present invention.

  As shown in FIG. 6, the waste cleaning apparatus 204 in the filth distribution of the present embodiment includes a first cleaning water discharge opening / closing valve 220 a and a second cleaning water discharge opening / closing valve 220 b as the flow rate adjusting means 220. The first washing water discharge opening / closing valve 220a and the second washing water discharge opening / closing valve 220b are provided in parallel between the outlet 14b of the T-shaped tube 14 and the washing water discharge opening 4a. In the present embodiment, the first cleaning water discharge opening / closing valve 220a and the second cleaning water discharge opening / closing valve 220b also function as cleaning water discharge opening / closing valves.

  When the cleaning foot switch 8 or the cleaning switch 12 is operated to discharge water only from the cleaning water discharge port 4a, the controller 222 sends a signal to the first cleaning water discharge opening / closing valve 220a to open it. Let Thereby, the wash water supplied from the water supply source S is discharged from the washing water discharge port 4a through the inlet 14c, the outlet 14b, and the first washing water discharge opening / closing valve 220a of the T-shaped tube 14. Here, since the first washing water discharge opening / closing valve 220a is configured to have a large flow path resistance when opened, the washing water discharged from the washing water discharge port 4a has an appropriate flow rate for washing the urine bottle and the like. To be.

  Next, when the flush foot switch 6 or the flush switch 10 is operated and water is discharged from the box rim 2b as well, the controller 222 opens the flush water discharge on-off valve 16 and at the same time the second washing water discharge The on-off valve 220b is opened. Here, the second washing water spouting on-off valve 220b is configured to have a small flow path resistance when opened. For this reason, even if the pressure of the washing water flowing into the outlet 14b is reduced by opening the flush water discharge opening / closing valve 16, the washing water is supplied to the first washing water discharge opening / closing valve 220a and the second washing water discharge opening / closing. Since water is discharged from the cleaning water outlet 4a through the valve 220b, the flow rate of the cleaning water discharged from the cleaning water outlet 4a is maintained substantially constant.

  Next, when the flush water discharge is completed and the flush water discharge opening / closing valve 16 is closed, the controller 222 also closes the second cleaning water discharge opening / closing valve 220b at the same time. As a result, when the flush water discharge is terminated, the water discharge flow rate from the cleaning water discharge port 4a is maintained substantially constant.

According to the dirty logistics of the second embodiment of the present invention, it is possible to easily maintain the water discharge flow rate from the cleaning water discharge port by using two on-off valves.

In this case, the flow path resistances of the pipes through which the washing water flows when the first and second washing water discharge opening / closing valves are opened are configured to be different.

  Next, with reference to FIG. 7, filth logistics according to the third embodiment of the present invention will be described. The dirty logistics of this embodiment differs from the first embodiment described above in the configuration of the flow rate adjusting means. Accordingly, here, only the points of the third embodiment of the present invention that are different from the first embodiment will be described, and description of similar configurations will be omitted. FIG. 7 is a block diagram showing a wastewater distribution water supply system according to a third embodiment of the present invention.

  As shown in FIG. 7, the filth washing apparatus 304 in the filth distribution of this embodiment has a two-stage on-off valve 320 as a flow rate adjusting means. The two-stage opening / closing valve 320 is provided between the outlet 14b of the T-tube 14 and the cleaning water outlet 4a. In addition, the two-stage opening / closing valve 320 is configured to be opened at a two-stage opening degree in a large flow rate mode and a small flow rate mode by a control signal. Further, in the present embodiment, the two-stage opening / closing valve 320 also functions as a cleaning water discharge opening / closing valve.

  When the cleaning foot switch 8 or the cleaning switch 12 is operated and the controller 322 is in a state where water is discharged only from the cleaning water outlet 4a, the controller 322 sends a signal to the two-stage on-off valve 320, and this is performed in the small flow rate mode. Open. As a result, the wash water supplied from the water supply source S is discharged from the washing water discharge port 4a through the inlet 14c, the outlet 14b, and the two-stage opening / closing valve 320 of the T-shaped tube 14. Here, since the two-stage on-off valve 320 opened in the small flow rate mode has a large flow path resistance, the cleaning water discharged from the cleaning water discharge port 4a is set to an appropriate flow rate for cleaning the urine bottle and the like. The

  Next, when the flash foot switch 6 or the flash switch 10 is operated and water is discharged from the box rim 2b, the controller 322 opens the flash water discharge opening / closing valve 16 and at the same time, the two-stage opening / closing valve 320. To switch to large flow mode. Here, since the two-stage open / close valve 320 opened in the large flow rate mode has a small flow resistance, the flush water flowing into the two-stage open / close valve 320 from the outlet 14b is opened by opening the flush water discharge on / off valve 16. Even if the pressure decreases, the flow rate of the cleaning water discharged from the cleaning water discharge port 4a is maintained substantially constant.

  Next, when the flush water discharge is completed and the flush water discharge opening / closing valve 16 is closed, the controller 322 simultaneously switches the two-stage opening / closing valve 320 to the small flow rate mode. As a result, when the flush water discharge is terminated, the water discharge flow rate from the cleaning water discharge port 4a is maintained substantially constant.

According to the dirty logistics of the third embodiment of the present invention, the water discharge flow rate from the cleaning water discharge port can be easily maintained almost constant by using the two-stage on-off valve.
Next, with reference to FIG. 8, the filth distribution according to the fourth embodiment of the present invention will be described. The dirty logistics of this embodiment differs from the first embodiment described above in the configuration of the flow rate adjusting means. Accordingly, here, only the points of the fourth embodiment of the present invention different from the first embodiment will be described, and the description of the same configuration will be omitted. FIG. 8 is a block diagram showing a wastewater distribution water supply system according to a fourth embodiment of the present invention.

  As shown in FIG. 8, the filth washing apparatus 404 for filth distribution according to the present embodiment can adjust the opening degree as the flow rate adjusting means 420 based on the pressure sensor 420a and the detected pressure of the pressure sensor 420a. And an opening degree opening / closing valve 420b. In the present embodiment, the opening adjustment on-off valve 420b also functions as an on-off valve for cleaning water discharge.

  The pressure sensor 420a is provided between the outlet 14b of the T-shaped tube 14 and the opening adjustment opening / closing valve 420b, and is configured to measure the pressure of the washing water flowing into the opening adjustment opening / closing valve 420b. Further, the pressure measured by the pressure sensor 420 a is configured to be sent to the controller 422. The controller 422 is configured to send a signal to the opening adjustment opening / closing valve 420b based on the pressure signal sent from the pressure sensor 420a to adjust the opening of the opening adjustment opening / closing valve 420b.

  When the cleaning foot switch 8 or the cleaning switch 12 is operated and the controller 422 is in a state where water is discharged only from the cleaning water outlet 4a, the controller 422 sends a signal to the opening adjustment opening / closing valve 420b to open it. At this time, since the pressure measured by the pressure sensor 420a is relatively high, the controller 422 opens the opening adjustment on-off valve 420b with a small opening. For this reason, the cleaning water discharged from the cleaning water outlet 4a is set to an appropriate flow rate for cleaning the urine bottle and the like.

  Next, when the flash foot switch 6 or the flash switch 10 is operated and water is discharged from the box rim 2b, the controller 422 opens the flash water discharge opening / closing valve 16. Thereby, the pressure measured by the pressure sensor 420a rapidly decreases. When the measured value of the pressure sent from the pressure sensor 420a decreases, the controller 422 sends a signal to the opening adjustment on / off valve 420b to increase the opening of the opening adjustment on / off valve 420b to meet the pressure drop. Thereby, even if the pressure of the washing water flowing into the opening adjustment opening / closing valve 420b from the outlet 14b decreases, the flow rate of the washing water discharged from the washing water discharge port 4a is maintained substantially constant.

  Next, when the flush water discharge is finished and the flush water discharge on-off valve 16 is closed, the pressure measured by the pressure sensor 420a rapidly increases. When the measured value of the pressure sent from the pressure sensor 420a rises, the controller 422 sends a signal to the opening adjustment on / off valve 420b to reduce the opening of the opening adjustment on / off valve 420b to match the pressure rise. Thereby, even if the pressure of the washing water flowing into the opening adjustment opening / closing valve 420b from the outlet 14b increases, the flow rate of the washing water discharged from the washing water discharge port 4a is maintained substantially constant.

  According to the filth distribution of the fourth embodiment of the present invention, the discharge water flow rate is adjusted using the pressure sensor and the opening adjustment on-off valve, so that the flow rate can be controlled more accurately and in the vicinity of the filth distribution. It is also possible to suppress the influence of water supply pressure fluctuations caused by other installed water supply devices.

  As mentioned above, although preferable embodiment of this invention was described, a various change can be added to embodiment mentioned above.
