Description

  The present invention relates to a urinal device, and in particular, a bowl unit rear storage chamber for storing a functional member for supplying cleaning water to the bowl unit is integrated with the bowl unit on the upper side and the rear side of the bowl unit that receives user's urine. The present invention relates to a urinal device that is formed.

  Conventionally, as shown in Patent Document 1, in the ceiling part of the bowl part, it is provided so as to protrude from the wall surface to the front surface on the user side, and functional parts such as a water supply valve, a stop cock, a controller, a spreader, etc. There is known a urinal device in which a storage chamber for storing the urinal is formed. In such a urinal device, the back side of the bottom surface of the storage chamber is connected to the upper portion of the bowl portion, and the spreader is disposed downward from the back side of the bottom surface of the storage chamber to discharge cleaning water into the bowl portion. ing.

  In such a urinal device, since the storage chamber is provided in the ceiling of the bowl portion and the spreader is provided on the bottom surface of the storage chamber, dirt or the like adhering to the front surface of the storage chamber is discharged from the spreader. There is a disadvantage that it cannot be washed with washing water. In order to solve such a drawback, as shown in Patent Document 2, the bowl portion is formed up to the front surface of the sub tank provided in the lower portion of the storage chamber, and the spreader is formed in the sub tank of the lower portion of the storage chamber. It is known to clean the front side of the lower part of the storage chamber with water discharged from the spreader by disposing it in the bowl part on the front side.

  However, there is a limited space where a storage chamber can be formed in the upper part of the urinal device to store functional parts such as a water supply valve, a stop cock, a controller, and a spreader. In particular, the entire functional part is stored behind the bowl part. When it is going to form the storage chamber which performs, it is necessary to arrange | position each functional member in the space further limited rather than the above-mentioned patent documents 1 and 2. Therefore, when the spreader, the water supply valve, etc. are to be stored in the storage chamber formed on the rear side of the bowl portion, it is necessary to downsize the entire functional portion and to arrange the height positional relationship of these members close to each other. .

  At this time, if the spreader and the water supply valve are arranged relatively close to each other, the remaining water remaining in the water supply pipe downstream from the water supply valve is closed after the water supply valve is closed in order to finish urinal cleaning. The phenomenon that the air flows out from the spreader and the air flows into the water supply pipe from the spreader to the water supply valve is likely to occur along with the outflow of the remaining water.

If a relatively large amount of air accumulates in the water supply pipe between the spreader and the water supply valve, the air that has accumulated in the water supply pipe will be renewed when the water supply valve is opened and water discharge is started for cleaning the urinal each time. There is a problem that a water discharge sound (for example, abnormal noise such as gobogobo) is generated when water is discharged from the water discharge portion in a state where water and air are mixed with the cleaning water supplied from the water supply valve. .
In addition, when the water supply valve is closed, there is also a problem that with the inflow of air, the residual water gradually flows out from the water supply pipe through the spreader to the bowl portion, causing the washing water to drip from the spreader. It was.

  In addition, when the water supply valve was opened to clean the urinal, the opening cross section of the spout of the spreader was small, so that it was difficult for air to escape immediately, and the newly supplied cleaning water accumulated in the water supply pipe. Air is compressed. Therefore, the wash water mixed with the compressed air is discharged together from the spout of the spreader. At this time, since the washing water containing these airs is suddenly released to the atmosphere, the compressed air spreads explosively at the moment when the compressed air comes out from the spout of the spreader. Due to the explosive spread, the washing water also scatters, causing a problem of water splashing.

  Therefore, the present invention has been made to solve the drawbacks of the prior art, and in a urinal apparatus in which a functional member for supplying cleaning water to the bowl portion is stored in the bowl portion rear storage chamber, The amount of air that accumulates can be reduced, and when the water supply valve unit starts supplying cleaning water to the water discharger, water is discharged while the cleaning water in the water supply tube and the accumulated air are mixed from the water discharger. The generation of water discharge noise due to being performed can be suppressed, and furthermore, after the water supply valve portion stops supplying the wash water to the water discharge portion, the wash water in the water supply pipe portion gradually flows to the water discharge portion, An object of the present invention is to provide a urinal device that can prevent dripping from a water discharge portion.

  The bowl portion rear storage chamber 20 is not disposed further above the bowl portion 6 that receives the user's urine, but on the rear side (back side) of the front side wall portion 7 of the bowl portion 6 that receives the user's urine. The functional member for supplying cleaning water to the bowl portion 6 is formed so as to be hidden behind the front side wall portion 7. As described above, the bowl portion rear storage chamber 20 includes the automatic washing unit 4 necessary for the washing operation of the urinal device 1 in a relatively narrow region formed in the gap between the bowl portion 6 and the rear wall surface W. It is formed compactly so that (functional member) can be accommodated. The front surface of the bowl portion rear storage chamber 20 is formed by the front side wall portion 7. The front side wall part 7 has its lower part located on the rear side with respect to its upper part, and has a slight downward inclination.

  The automatic cleaning unit 4 housed in the bowl rear storage chamber 20 includes a primary side water supply pipe 22 that supplies cleaning water from a water supply source such as a water supply, a water stop cock 24 that stops the primary side water supply pipe 22, A water supply valve unit 26 provided on the downstream side of the water faucet 24 to open and close the primary water supply pipe 22 and cleaning water supplied from the water supply valve unit 26 disposed on the front side wall portion 7 at the upper part of the bowl portion 6. 6 includes a spreader (water supply means) 28 that is a water discharge portion for discharging water, and a first water supply pipe portion 32 that connects the inlet portion 30 of the spreader 28 and the water supply valve unit 26.

The water supply valve unit 26 has an electromagnetic valve 29 that can electrically open and close a flow path between the primary side water supply pipe 22 and the secondary side water supply pipe, and a secondary side flow path 31 that extends downward from the electromagnetic valve. are doing. The secondary side flow path 31 communicates with a first water supply pipe section 32 and a spreader 28 on the air release side, which will be described later.
The water supply valve unit 26 is disposed at a position shifted to the rear side and the right side of the spreader 28 in a relatively small and limited space of the bowl portion rear storage chamber 20. The electromagnetic valve 29 is arranged at a height substantially the same as the height of the spreader 28. The secondary side flow path 31 extends downward from the electromagnetic valve 29, and the connection portion between the secondary side flow path 31 of the water supply valve unit 26 and the first water supply pipe portion 32 is disposed at a position lower than the height of the inlet portion 30. ing. Although the solenoid valve 29 is disposed at a position relatively close to the spreader 28, the secondary-side flow path 31 does not extend in the direction of the shortest distance connecting the solenoid valve 29 and the spreader 28, and is directed downward. It extends.
In the present embodiment, the electromagnetic valve 29 of the water supply valve unit 26 is disposed at a height substantially the same as the height of the spreader 28, but may be disposed at a height lower than the height of the spreader 28. Moreover, it may be arranged at a height higher than the height of the spreader 28.

The spreader 28 includes an inlet portion 30 for cleaning water disposed in the bowl portion rear storage chamber 20, a supply passage 33 extending linearly from the back side of the front side wall portion 7 of the bowl portion 6 to the front side, and a supply passage 33. A water discharge port 34 that discharges the cleaning water supplied from the water along the surface of the bowl 6 and diffuses it.
The spreader 28 is provided with a human body detection sensor 36 that faces the front surface of the bowl portion 6 and detects the presence or absence of a user.

The automatic cleaning unit 4 further includes a control unit 38 that can electrically control the water supply valve unit 26 and the like based on a detection signal from the human body detection sensor 36 and a predetermined control program.
The control unit 38 controls opening / closing of the water supply valve unit 26 based on a detection signal from the human body detection sensor 36 and a predetermined control program, and discharges the cleaning water from the spreader 28 to the bowl portion 6. The control unit 38 is also accommodated in a relatively small and limited space in the bowl portion 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, at least a part of the flow path having a height lower than the height of the inlet portion 30 of the spreader 28 is provided between the inlet portion 30 and the electromagnetic valve 29. In addition, the electromagnetic valve 29 of the water supply valve unit 26 may be disposed at a position higher than the inlet portion 30, and in that case, the first water supply pipe portion 32 is disposed at a position higher than the inlet portion 30. 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 electromagnetic valve 29. Formed as follows.

  The first water supply pipe portion 32 is connected to the inlet portion 30 of the spreader 28, and forms a downward inclined flow path from the inlet portion 30 of the spreader 28 toward the upstream side (water supply valve unit 26 side). It has the pipe connection part 40 and the lowest end part 42 which forms the flow path of the lowest end part of the 1st water supply pipe part 32. The lowermost end portion 42 of the first water supply pipe portion 32 is disposed at a position lower than the inlet portion 30 of the spreader 28. Furthermore, the lowermost end portion 42 of the first water supply pipe portion 32 is disposed at a position lower than 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 inlet portion 30 to be connected, when the supply of cleaning water from the electromagnetic valve 29 is stopped, the inlet of the spreader 28 is stopped. The cleaning water existing on the upstream side of the section 30 is stored in the first water supply pipe section 32 as it is. That is, in a state in which water discharge to the toilet body 2 is stopped, the wash water is in a state where it is accumulated below the horizontal surface of the inlet 30 of the spreader 28 in the first water supply pipe 32. . As described above, the first water supply pipe portion 32 is configured to allow air to flow between the water supply valve unit 26 and the inlet portion 30 of the spreader 28 to the upstream side immediately before the inlet portion 30 after the water supply valve unit 26 is closed. The water storage part 44 which can form the water storage surface of the remaining water w1 which prevents is formed. That is, a water surface having a height at the bottom of the inlet portion 30 is formed immediately before the inlet portion 30. Therefore, it can be suppressed that air flows into the first water supply pipe portion 32 from the outside of the spreader 28 and the air is accumulated in the first water supply pipe portion 32. In other words, the upstream side of the remaining water w1 of the first water supply pipe portion 32 can be filled with water.

  The first water supply pipe portion 32 is formed so as to be flexible by a member such as a hose or a flexible rubber tube, and extends while being curved from the inlet portion 30 to the water supply valve unit 26. The 1st water supply pipe part 32 may have a linear part, and all may be formed of the curved part. The flow path shape of the 1st water supply pipe part 32 can be changed freely. In the present embodiment, the entire first water supply pipe portion 32 is disposed 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 disposed on the bowl surface formed downward, the water supply pipe connected to the spreader is rearwardly upward and perpendicular to the bowl surface. The washing water flows down to the spreader while accelerating smoothly in the water supply pipe, and water is 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 that water can be discharged along the front side wall portion 7 inclined downward. Thus, a flow path descending from the inlet portion 30 of the spreader 28 toward the upstream side is formed. Therefore, in the present invention, the residual water can be accumulated as described above up to the vicinity of the inlet 30 of the spreader 28.

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

  When the user finishes urination in the bowl portion 6 of the toilet body 2 and the user who has finished urination leaves from the front of the toilet body 2, the human body detection sensor 36 changes to a state where it does not detect the presence of the user. When the human body detection sensor 36 changes to the non-detection state after continuing the detection state for a predetermined time or longer, the control unit 38 recognizes that the user has left the toilet body 2 and starts the urine washing 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 discharge the previously determined amount of cleaning water from the spreader 28 to the bowl portion 6. At this time, in a state before the water supply valve unit 26 is opened, the wash water has already accumulated in the first water supply pipe connection portion 40 in the first water supply pipe portion 32 up to the height of the inlet portion 30 of the spreader 28. In this state, the water storage section 44 is formed. 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 to supply the cleaning water to the spreader 28, the water is discharged from the spreader 28 in a mixed state of the cleaning water and the air accumulated in the first water supply pipe portion 32. Generation | occurrence | production of the water discharge sound (for example, unusual noises, such as gobogobo), can be suppressed.

  The washing water is discharged from the spreader 28 to the bowl portion 6 to wash the bowl portion 6 and discharge 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 cleaning water from the spreader 28. After a predetermined time has elapsed, the control unit 38 closes the water supply valve unit 26 and ends the urine washing operation. When the water supply valve unit 26 is closed, the discharge of the washing water is finished and the standby state is restored.

When the water supply valve unit 26 is closed, the cleaning 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 indicated by the residual water w1). State). That is, the cleaning water is accumulated in the first water supply pipe connection portion 40 in the first water supply pipe section 32 up to the height of the inlet 30 of the spreader 28, thereby forming the water storage section 44. Accordingly, it is possible to prevent the first water supply pipe portion 32 from being released into 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 section 32, the first water supply pipe section 32 connected to the inlet section 30 is in a state where air is not accumulated or the amount of accumulated air is reduced. The amount of air that accumulates has been reduced.
Therefore, when the water supply valve unit 26 is opened from the closed state for each urinal washing operation, the amount of air that has 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, each time (every time), when the water supply valve unit 26 starts supplying the cleaning water to the spreader 28, the air is compressed and mixed with the cleaning water in the first water supply pipe section 32, and the cleaning is performed from the spreader 28. Generation of water discharge sound (for example, abnormal noise such as gobogobo) due to water discharge in a state where water and air are mixed can be suppressed.

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

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

  In order to protect not only the urinal washing operation for washing the urinal device after the user uses the urinal device 1, but also the equipment such as the drain pipe that the control unit 38 performs based on its own judgment. Also in the equipment protection cleaning operation, when the water supply valve unit 26 is closed, similarly, the cleaning water existing in the first water supply pipe portion 32 is accumulated at a position lower than the inlet portion 30 of the spreader 28. It is said.

Furthermore, the lowermost end portion 152 of the second water supply pipe portion 148 is disposed at a position lower than the water supply valve unit 126.

  The second water supply pipe section 148 forms a flow path that descends from the vicinity immediately upstream of the inlet section 130 to be connected. Therefore, when the supply of cleaning water from the solenoid valve 29 is stopped, the inlet of the spreader 28 is stopped. The cleaning water existing on the upstream side of the section 130 is stored in the second water supply pipe section 148 as it is. That is, in a state where water discharge from the urinal device 101 is stopped, the wash water is in a state where the water is accumulated below the horizontal surface of the inlet portion 130 of the spreader 28 in the second water supply pipe portion 148. . As described above, the second water supply pipe portion 148 has an air inflow between the generator unit 146 and the inlet portion 130 of the spreader 28, after the water supply valve unit 126 is closed, upstream immediately before the inlet portion 130. The water storage part 154 which can form the water storage surface of the remaining water w2 which prevents water is formed. Therefore, in the vicinity of the inlet portion 130, it is possible to prevent air from flowing into or collecting in the second water supply pipe portion 148.

  The second water supply pipe portion 148 is formed to have flexibility, and extends from the inlet portion 130 to the generator unit 146 while being curved. The flow path shape of the 2nd water supply pipe part 148 can be changed freely. In the present embodiment, the entire second water supply pipe portion 148 is disposed at a position lower than the inlet portion 130 of the spreader 28.

  Next, the operation (action) of the urinal apparatus according to the second embodiment of the present invention will be described with reference to FIGS. Here, only different points of the second embodiment of the present invention from the first embodiment will be described, and the same parts are denoted by the same reference numerals and the description thereof will be omitted.

  As shown in FIGS. 6 to 9, in the standby state before the user urinates, the cleaning water exists as residual water w <b> 1 in the first water supply pipe portion 32 up to the height of the inlet portion 130 of the spreader 28. In the second water supply pipe portion 148, the cleaning water exists as residual water w2 up to the height of the inlet portion 130 of the spreader 28.

  The control unit 38 recognizes that the user has left the toilet body 2 when the user has finished urinating the bowl 6 of the toilet body 2 and the user who has finished urination has left the front of the toilet body 2. The urine washing operation is started.

The control unit 38 sends a control signal to the water supply valve unit 126 to open the electromagnetic valve 29 of the water supply valve unit 126, and discharges the previously determined amount of cleaning water from the spreader 28 to the bowl portion 6.
At this time, in a state before the electromagnetic valve 29 is opened, the cleaning water has already accumulated up to the height of the inlet portion 130 of the spreader 28 in the first water supply pipe connection portion 40 in the first water supply pipe portion 32. The water reservoir 44 is formed. In addition, the wash water is accumulated up to the height of the inlet portion 130 of the spreader 28 in the second water supply pipe connection portion 150 in the second water supply pipe portion 148, thereby forming the water storage portion 44. Therefore, the air is not accumulated in both 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 the air accumulated is reduced.
Therefore, when the water supply valve unit 126 starts to supply the cleaning water to the spreader 28, the cleaning water and the air accumulated in the first water supply pipe portion 32 and the second water supply pipe portion 148 are mixed. It is possible to suppress the generation of water discharge sound (for example, abnormal noise such as gobogobo) due to water being discharged in a wet state.

  The control unit 38 opens the water supply valve unit 126 over a predetermined time, and discharges a predetermined amount of cleaning water from the spreader 28. After a predetermined time has elapsed, the control unit 38 closes the water supply valve unit 126 and ends the urine washing operation. When the water supply valve unit 126 is closed, the discharge of the washing water is finished and the standby state is restored.

When the water supply valve unit 126 is closed, the cleaning 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). State). That is, the cleaning water is accumulated in the first water supply pipe connection portion 40 in the first water supply pipe section 32 up to the height of the inlet 130 of the spreader 28, thereby forming the water storage section 44. Accordingly, it is possible to prevent the first water supply pipe portion 32 from being released into 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 section 32, the first water supply pipe section 32 connected to the inlet section 130 is in a state where air is not accumulated or the amount of accumulated air is reduced. The amount of air that accumulates has been reduced.
In addition, the wash 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 is present as shown in the residual water w2). That is, the wash water is accumulated in the second water supply pipe connection 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 second water supply pipe portion 148 from being released into the atmosphere and a large amount of air from being accumulated in the second water supply pipe portion 148. In the 2nd water supply pipe part 148, it is in the state where air has not accumulated in the 2nd water supply pipe part 148 connected to the entrance part 130, or the quantity which has accumulated is reduced, and in the 2nd water supply pipe part 148 The amount of air that accumulates has been reduced.

  Therefore, when the water supply valve unit 126 is opened from the closed state for each urinal washing operation, air does not collect or collect in the first water supply pipe portion 32 and the second water supply pipe portion 148 connected to the inlet portion 130. The amount is reduced. Therefore, each time (every time), when the water supply valve unit 126 starts to supply the cleaning water to the spreader 28, the air is compressed and cleaned in the first water supply pipe section 32 and / or the second water supply pipe section 148. Water discharge sound (for example, gobogobo or the like) that is mixed with water and discharged from the spreader 28 in a state where the wash water and the air accumulated in the first water supply pipe portion 32 and / or the second water supply pipe portion 148 are mixed. ) Can be suppressed.

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

  Further, when the water supply valve unit 126 starts to supply the wash water to the spreader 28 in order to start the urinal cleaning operation, the water is collected in the first water supply pipe portion 32 and / or the second water supply pipe portion 148. The compressed air can be prevented 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 as soon as it exits the spreader 28. It spreads, and it is possible to prevent water from splashing due to splashing of the washing water in accordance with the bursting.

  In addition to the urinal washing operation for washing the urinal device 101 after the user uses the urinal device 101, the control unit 38 protects facilities such as a drain pipe as performed based on its own judgment. Also in the equipment protection cleaning operation for this, 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. It is set as the state which accumulated in the lower position.

Next, functions and effects of the urinal device 101 according to the second embodiment of the present invention described above will be described.

In this case, the remaining water surface that prevents the inflow of air can be formed by accumulating washing water, and the amount of air accumulated in the second water supply pipe portion 148 can be reduced.
Accordingly, since it is possible to suppress the accumulation of air in the second water supply pipe portion 148, when the water supply valve unit 126 starts supplying the wash water to the spreader 28, the wash water and the reservoir in the second water supply pipe portion 148 are collected. It is possible to suppress the generation of water discharge sound due to water being discharged while the air that has been mixed from the spreader 28 is discharged.
Further, after the water supply valve unit 126 stops supplying the cleaning water to the water discharge part, the cleaning water in the second water supply pipe part 148 gradually flows into the spreader 28 and prevents dripping from the spreader 28. be able to.
