The control unit 38 is also housed in a relatively small and limited space of the bowl rear storage chamber 20.

The first water supply pipe portion 32 has at least a part of a flow path having a height lower than the height of the inlet portion 30 of the spreader 28 between the inlet portion 30 of the spreader 28 and the water supply valve unit 26. More specifically, between the inlet portion 30 and the solenoid valve 29, there is at least a part of a flow path having a height lower than the height of the inlet portion 30 of the spreader 28. The solenoid valve 29 of the water supply valve unit 26 may be arranged at a position higher than the inlet portion 30, and in that case, the first water supply pipe portion 32 is arranged at a position higher than the inlet portion 30. It is connected to the valve unit 26, and at this time, the first water supply pipe portion 32 has at least a part of a flow path having a height lower than the height of the inlet portion 30 of the spreader 28 between the inlet portion 30 and the solenoid valve 29. Is formed as follows.

The first water supply pipe portion 32 is connected to the inlet portion 30 of the spreader 28, and forms a downwardly sloping flow path from the inlet portion 30 of the spreader 28 toward the upstream side (water supply valve unit 26 side). It has a pipe connecting portion 40 and a lower end portion 42 forming a flow path of the lowermost lower end portion of the first water supply pipe portion 32. The lowermost end portion 42 of the first water supply pipe portion 32 is arranged at a position lower than the inlet portion 30 of the spreader 28. Further, the lowermost end portion 42 of the first water supply pipe portion 32 is arranged at a position lower than that of the water supply valve unit 26.

Since the first water supply pipe portion 32 forms a flow path that descends from the vicinity immediately upstream of the connected inlet portion 30, when the supply of wash water from the solenoid valve 29 is stopped, the inlet of the spreader 28 The washing water existing on the upstream side of the portion 30 is in a state of being stored in the first water supply pipe portion 32 as it is. That is, with the water discharge to the toilet bowl body 2 stopped, the washing water is collected in the first water supply pipe portion 32 below the horizontal surface at the height of the inlet portion 30 of the spreader 28. .. As described above, in the first water supply pipe portion 32, air flows into the upstream side immediately before the inlet portion 30 after the water supply valve unit 26 is closed between the water supply valve unit 26 and the inlet portion 30 of the spreader 28. A water storage portion 44 capable of forming a water storage surface of the residual water w1 is formed. That is, immediately before the inlet portion 30, a water surface at the height of the bottom of the inlet portion 30 is formed. Therefore, it is possible to prevent the air from flowing into the first water supply pipe portion 32 from the outside of the spreader 28 and the air from accumulating in the first water supply pipe portion 32. In other words, the upstream side of the residual water w1 of the first water supply pipe portion 32 from the water storage surface can be filled with water.

The first water supply pipe portion 32 is formed to have flexibility by a member such as a hose or a flexible rubber pipe, and extends from the inlet portion 30 to the water supply valve unit 26 while being curved. The first water supply pipe portion 32 may have a straight portion, or may be formed entirely of curved portions. The shape of the flow path of the first water supply pipe portion 32 can be freely changed. In the present embodiment, all of the first water supply pipe portion 32 is arranged at a position lower than the inlet portion 30 of the spreader 28.

Conventionally, as shown in Patent Document 2, when the spreader is to be arranged on the bowl surface formed downward, the water supply pipe connected to the spreader is rearwardly and upwardly perpendicular to the bowl surface. The wash water was smoothly accelerated in the water supply pipe and flowed down to the spreader, and was discharged so as to be spread from the spreader.
On the other hand, in the present invention, the first water supply pipe portion 32 is connected to the spreader 28 arranged so as to be able to discharge water along the front side wall portion 7 inclined downward while being raised from below. Then, a flow path is formed which descends from the inlet portion 30 of the spreader 28 toward the upstream side. Therefore, in the present invention, the residual water can be stored up to the vicinity of the inlet portion 30 of the spreader 28 as described above.

Next, the operation (action) according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 5.
In the standby state, when the user normally stands in front of the toilet body 2 to urinate, the human body detection sensor 36 detects the presence of the user and sends the detection information to the control unit 38, and the control unit 38 sends the detection information to the user. Recognize the existence of. As shown in FIG. 4, in the standby state before the user urinates, the washing water is present in the first water supply pipe portion 32 as the residual water w1 up to the height of the inlet portion 30 of the spreader 28. ing.
When the user urinates in the bowl portion 6 of the toilet bowl body 2, urine flows from the bowl portion 6 into the drain trap portion 12.

When the user finishes urinating in the bowl portion 6 of the toilet bowl body 2 and the user who has finished urinating leaves from the front of the toilet bowl body 2, the human body detection sensor 36 changes to a state in which the presence of the user is not detected. When the human body detection sensor 36 changes to the non-detection state after continuing the detection state for a certain period of time or more, the control unit 38 recognizes that the user has left the toilet bowl main body 2 and starts the urine cleaning operation.

The control unit 38 sends a control signal to the water supply valve unit 26 to open the water supply valve unit 26, and discharges a previously determined amount of washing water from the spreader 28 to the bowl portion 6. At this time, in the state before the water supply valve unit 26 is opened, the washing water has already accumulated in the first water supply pipe connecting portion 40 in the first water supply pipe portion 32 up to the height of the inlet portion 30 of the spreader 28. It is in a state of forming a water storage unit 44. Therefore, when the water supply valve unit 26 is opened, air is not accumulated in the first water supply pipe portion 32 connected to the inlet portion 30, or the amount of accumulated air is reduced. Therefore, when the water supply valve unit 26 starts supplying the washing water to the spreader 28, the washing water and the air accumulated in the first water supply pipe portion 32 are discharged from the spreader 28 in a mixed state. It is possible to suppress the generation of water discharge noise (for example, abnormal noise such as gurgling).

The washing water is discharged from the spreader 28 to the bowl portion 6, washing the bowl portion 6 and discharging the urine in the drain trap portion 12. The control unit 38 opens the water supply valve unit 26 for a predetermined time, and discharges a predetermined amount of wash water from the spreader 28. After a lapse of a predetermined time, the control unit 38 closes the water supply valve unit 26 and ends the urine cleaning operation. When the water supply valve unit 26 is closed, the discharge of the washing water is completed and the state returns to the standby state.

When the water supply valve unit 26 is closed, the washing water in the first water supply pipe portion 32 is accumulated at a position lower than the inlet portion 30 of the spreader 28 (the presence of residual water as shown in the residual water w1). It becomes the state of doing). That is, the washing water is accumulated in the first water supply pipe connecting portion 40 in the first water supply pipe portion 32 up to the height of the inlet portion 30 of the spreader 28, and the water storage portion 44 is formed. Therefore, it is possible to prevent the inside of the first water supply pipe portion 32 from being opened to the atmosphere and a large amount of air from being accumulated in the first water supply pipe portion 32. In the first water supply pipe portion 32, air is not accumulated in the first water supply pipe portion 32 connected to the inlet portion 30, or the amount of accumulated air is reduced, and the inside of the first water supply pipe portion 32 is in a state of being reduced. The amount of air that collects is reduced.
Therefore, when the water supply valve unit 26 is opened from the closed state for each urinal cleaning operation, the amount of air not accumulated or accumulated in the first water supply pipe portion 32 connected to the inlet portion 30 is reduced. It becomes a state. Therefore, when the water supply valve unit 26 starts supplying the washing water to the spreader 28 each time (every time), the air is compressed in the first water supply pipe portion 32 and mixed with the washing water to wash from the spreader 28. It is possible to suppress the generation of water discharge noise (for example, abnormal noise such as gurgling) due to water discharge in a state where water and air are mixed.

Further, since the first water supply pipe connecting portion 40 forms a flow path that descends from the inlet portion 30 toward the upstream side, it exists in the first water supply pipe portion 32 when the water supply valve unit 26 is closed. The washing water to be washed is stored in the upstream side from the inlet portion 30. Therefore, it is possible to prevent the washing water from gradually flowing out from the inlet portion 30 of the spreader 28 and causing dripping from the spout portion 34.

Further, when the water supply valve unit 26 starts supplying the washing water to the spreader 28 in order to start the urinal washing operation, the air accumulated in the first water supply pipe portion 32 is compressed and compressed. It is possible to prevent the water from being discharged from the spreader 28 in a state where the air and the washing water are mixed, and the compressed air spreads explosively at the moment when it comes out of the spreader 28, and the explosive spreading causes the washing water. Can be prevented from splashing and causing water splash.

In addition to the urinal cleaning operation in which the user cleans the urinal device after using the urinal device 1, the control unit 38 protects equipment such as a drain pipe that is performed based on its own judgment. In the equipment protection cleaning operation of the above, when the water supply valve unit 26 is closed, the cleaning water existing in the first water supply pipe portion 32 is similarly accumulated at a position lower than the inlet portion 30 of the spreader 28. It is said that.

After the unit 26 stops supplying the washing water to the spreader 28, the first water supply pipe connecting portion 40 of the first water supply pipe portion 32 forms a downward slope from the inlet portion 30 of the spreader 28 toward the upstream side. In the above, the cleaning water can be stored to form the residual water surface of the residual water w1 that prevents the inflow of air, and the amount of air accumulated in the first water supply pipe portion 32 can be reduced.
Therefore, since it is possible to suppress the accumulation of air in the first water supply pipe portion 32, when the water supply valve unit 26 starts supplying the washing water to the spreader 28, the cleaning water and the accumulation in the first water supply pipe portion 32 are accumulated. It is possible to suppress the generation of water discharge noise due to the water being discharged from the spreader 28 in a mixed state.
Further, after the water supply valve unit 26 stops supplying the washing water to the spreader 28, the washing water in the first water supply pipe portion 32 gradually flows to the spreader 28 to prevent the spreader 28 from dripping. be able to.

According to the urinal device 1 according to the first embodiment of the present invention, after the water supply valve unit 26 stops supplying the washing water to the spreader 28, the first water supply pipe portion 32 is more than the inlet portion 30 of the spreader 28. Washing water can be accumulated in all of the first water supply pipes 32 arranged at a low position, and the amount of air accumulated in the first water supply pipes 32 can be further reduced.
Therefore, since the amount of air accumulated in the first water supply pipe portion 32 can be further suppressed, when the water supply valve unit 26 starts supplying the washing water to the spreader 28, the cleaning water in the first water supply pipe portion 32 and the cleaning water It is possible to suppress the generation of water discharge noise due to the accumulated air being discharged from the spreader 28 in a mixed state.

Then, the urination cleaning operation is started.

The control unit 38 sends a control signal to the water supply valve unit 126 to open the solenoid valve 29 of the water supply valve unit 126, and discharges a previously determined amount of washing water from the spreader 28 to the bowl portion 6.
At this time, in the state before the solenoid valve 29 is opened, the washing water has already accumulated up to the height of the inlet portion 130 of the spreader 28 at the first water supply pipe connecting portion 40 in the first water supply pipe portion 32. It is in a state of forming the water storage unit 44. Further, the washing water is accumulated up to the height of the inlet portion 130 of the spreader 28 at the second water supply pipe connecting portion 150 in the second water supply pipe portion 148 to form the water storage portion 44. Therefore, air is not accumulated in any of the first water supply pipe portion 32 and the second water supply pipe portion 148 connected to the inlet portion 130, or the amount of accumulated air is reduced.
Therefore, when the water supply valve unit 126 starts supplying the washing water to the spreader 28, the washing water and the air accumulated in the first water supply pipe portion 32 and the second water supply pipe portion 148 are mixed from the spreader 28. It is possible to suppress the generation of water discharge noise (for example, abnormal noise such as gurgling) due to water discharge in the state of being spouted.

The control unit 38 opens the water supply valve unit 126 for a predetermined predetermined time, and discharges a predetermined amount of wash water from the spreader 28. After a lapse of a predetermined time, the control unit 38 closes the water supply valve unit 126 to end the urine cleaning operation. When the water supply valve unit 126 is closed, the discharge of the washing water is completed and the state returns to the standby state.

When the water supply valve unit 126 is closed, the wash water in the first water supply pipe portion 32 is accumulated at a position lower than the inlet portion 130 of the spreader 28 (the presence of residual water as shown in the residual water w1). It becomes the state of doing). That is, the washing water is accumulated in the first water supply pipe connecting portion 40 in the first water supply pipe portion 32 up to the height of the inlet portion 130 of the spreader 28, and the water storage portion 44 is formed. Therefore, it is possible to prevent the inside of the first water supply pipe portion 32 from being opened to the atmosphere and a large amount of air from being accumulated in the first water supply pipe portion 32. In the first water supply pipe portion 32, air is not accumulated in the first water supply pipe portion 32 connected to the inlet portion 130, or the amount of accumulated air is reduced, and the inside of the first water supply pipe portion 32 is in a state of being reduced. The amount of air that collects is reduced.
Further, the washing water in the second water supply pipe portion 148 is in a state of being accumulated at a position lower than the inlet portion 130 of the spreader 28 (a state in which residual water exists as shown in the residual water w2). That is, the washing water is accumulated in the second water supply pipe connecting portion 150 in the second water supply pipe portion 148 up to the height of the inlet portion 130 of the spreader 28, and the water storage portion 154 is formed. Therefore, it is possible to prevent the inside of the second water supply pipe portion 148 from being opened to the atmosphere and a large amount of air from being accumulated in the second water supply pipe portion 148. In the second water supply pipe portion 148, air is not accumulated in the second water supply pipe portion 148 connected to the inlet portion 130, or the amount of accumulated air is reduced, and the inside of the second water supply pipe portion 148 is in a state of being reduced. The amount of air that collects is reduced.

Therefore, when the water supply valve unit 126 is opened from the closed state for each urinal cleaning operation, air is not accumulated or accumulated in the first water supply pipe portion 32 and the second water supply pipe portion 148 connected to the inlet portion 130. The amount of waste is reduced. Therefore, when the water supply valve unit 126 starts supplying the washing water to the spreader 28 each time (every time), the air is compressed and washed in the first water supply pipe portion 32 and / or the second water supply pipe portion 148. Water discharge sound (for example, gobogobo, etc.) due to being mixed with water and discharged from the spreader 28 in a state where the washing water and the air accumulated in the first water supply pipe portion 32 and / or the second water supply pipe portion 148 are mixed. It is possible to suppress the occurrence of abnormal noise).

Further, since the first water supply pipe connecting portion 40 forms a flow path that descends from the inlet portion 130 toward the upstream side, it exists in the first water supply pipe portion 32 when the water supply valve unit 126 is closed. The washing water to be washed is stored on the upstream side from the inlet 130. Therefore, it is possible to prevent the washing water from gradually flowing out from the inlet 130 of the spreader 28 and causing dripping from the spout 34.
Further, since the second water supply pipe connecting portion 150 forms a flow path that descends from the inlet portion 130 toward the upstream side, it exists in the second water supply pipe portion 148 when the water supply valve unit 126 is closed. The washing water to be washed is stored on the upstream side from the inlet 130. Therefore, it is possible to prevent the washing water from gradually flowing out from the inlet 130 of the spreader 28 and causing dripping from the spout 34.

Further, when the water supply valve unit 126 starts supplying the washing water to the spreader 28 in order to start the urinal cleaning operation, it is accumulated in the first water supply pipe portion 32 and / or the second water supply pipe portion 148. It is possible to prevent the compressed air from being discharged from the spreader 28 in a state where the compressed air and the washing water are mixed so that the compressed air bursts at the moment when it comes out of the spreader 28. It is possible to prevent the washing water from spreading and splashing as the rupture occurs.

It should be noted that not only the urinal cleaning operation of cleaning the urinal device 101 after the user uses the urinal device 101, but also the control unit 38 protects equipment such as a drain pipe that is performed based on its own judgment. In the equipment protection cleaning operation for this purpose, when the water supply valve unit 126 is closed, the cleaning water existing in the first water supply pipe portion 32 and the second water supply pipe portion 148 is similarly transferred to the inlet portion 130 of the spreader 28.
