Description

  The present invention relates to a urinal apparatus that allows a cleaning liquid to flow through a toilet that receives sewage such as urine, and collects and reuses the flowed cleaning liquid.

Conventionally, as this kind of urinal apparatus, what was described in patent document 1 (Unexamined-Japanese-Patent No. 7-216958) is known, for example.
As shown in FIG. 12, this urinal device Sa includes a toilet 1 that receives sewage such as urine and is flushed with sewage, and the sewage and the wash water that have entered the toilet 1 are in the lower part of the toilet 1. It is discharged from the provided outlet 1a. Connected to the discharge port 1a is a three-way switching valve 2 which can be switched by selecting opening and closing of the one side 2a and the other side 2b. A sewage tank 3 is connected to one side 2a of the switching valve 2, and a wash water tank 4 is connected to the other side 2b.

Further, the urinal device Sa includes a pump 4a for allowing flush water to flow into the toilet 1, a detection sensor 6 for detecting a user of the toilet 1, and a switching valve 2 and a pump 4a based on the detection of the detection sensor 6. And a control means 7 for controlling the operation.
This control means 7 always makes the switching valve 2 block both the one side 2a and the other side 2b, and makes it wait. And if the detection sensor 6 detects the user of the toilet bowl 1, the control means 7 will make the switching valve 2 block | close only the other side 2b, open one side 2a, and make the discharge port 1a and the sewage tank 3 communicate, The sewage poured into the toilet 1 is caused to flow into the sewage tank 3.

Next, when the user leaves and the detection sensor 6 no longer detects the user, the control means 7 operates the pump 4a to cause the cleaning water in the cleaning water tank 4 to flow into the 2000 cc toilet 1. At this time, the wash water is mixed with the sewage remaining in the toilet 1 and the wash water having a high concentration of sewage flows into the sewage tank 3. Then, when the cleaning water flows into the 200 cc (10% of flowing cleaning water) sewage tank 3 after the pump 4a is operated, the control means 7 causes the switching valve 2 to close only one side 2a and open the other side 2b. Then, the discharge port 1a and the washing water tank 4 are communicated. At this time, the remaining 1800 cc of the wash water is mixed with a little sewage remaining in the toilet 1, and the wash water having a low concentration of sewage flows into the wash water tank 4. Then, when the pump 4a finishes flowing 2000 cc of washing water, the control means 7 causes the switching valve 2 to block both the one side 2a and the other side 2b again and waits until the next user of the toilet 1 comes. In this state, since both the one side 2a and the other side 2b are closed, the odor from the sewage tank 3 is blocked.
The cleaning water tank 4 is supplied with new cleaning water from a cleaning water supply unit (not shown) for the amount of cleaning water reduced. Further, the cleaning water tank 4 contains a purification device having activated carbon or the like.

JP 7-216958 A

By the way, in such a conventional urinal apparatus Sa, about 10% of the washed water contaminated at the initial stage of washing is thrown away into the sewage tank 3 as sewage every time it is used. At the same time, there was a problem that the amount of sewage discharged increased by the amount of the washing water.
In addition, the wash water tank 4 is replenished with the wash water consumed by flowing into the sewage tank 3, but the amount of wash water thrown into the sewage tank 3 as described above is extremely large at about 10%. However, the frequency of replenishment increases, and there is a problem that the device becomes complicated and management becomes complicated, such as providing a device for replenishment separately.

  The present invention has been made in view of the above-mentioned problems. With a simple structure, the cleaning liquid is separated and recovered from the sewage so that the cleaning liquid can hardly be mixed into the sewage, reducing the overall discharge amount and replenishing the cleaning liquid. It aims at providing the urinal apparatus which reduced the frequency significantly.

  The urinal device of the present invention for achieving such an object includes a toilet that receives sewage such as urine and through which a cleaning liquid is allowed to flow, and the sewage and the cleaning liquid that have entered the toilet are provided at a lower portion of the toilet. In the urinal apparatus that discharges from the outlet and collects and reuses the discharged cleaning liquid, the cleaning liquid is configured with a fluid having a specific gravity greater than that of sewage and capable of phase separation, and is connected to the toilet outlet. A container having an upper portion in the container, and an upper opening in the upper portion of the container and a lower opening in the outer portion of the container. A discharge pipe section for allowing the separated and floated sewage to flow into the upper opening and out of the lower opening, a pump for sucking and collecting the cleaning liquid that has separated from the sewage and subsided in the container, and the pump Collect the cleaning solution It has a configuration that includes a feeder to flow.

According to this, when sewage is poured into the toilet bowl, the sewage is discharged from the outlet and flows into the container from the inlet of the container. In the container, since the cleaning liquid has a higher specific gravity than the sewage, the sewage that flows into the container floats above the cleaning liquid and accumulates on the upper side of the container. The sewage that has emerged from will be discharged.
When the pump is operated before, during or after the discharge process, the cleaning liquid is sucked and the cleaning liquid is passed through the toilet through the feeding section. As a result, the toilet bowl is washed with the flow of the washing liquid, and the washing liquid is discharged from the outlet of the toilet bowl and flows into the container from the inlet of the container. In the container, since the washing liquid has a higher specific gravity than the sewage, the washing liquid flowing into the container is phase-separated from the sewage and sinks.
In this case, since the washing liquid has a higher specific gravity than the sewage and can be phase-separated, the washing liquid and the sewage are well separated in the container. Can be reduced. In this cleaning, the cleaning liquid is consumed in a slightly mixed manner with the sewage, but since the consumption of the cleaning liquid is extremely small, the replenishment frequency of the cleaning liquid is greatly reduced compared to the conventional case, and the management efficiency is improved. Can be improved. Further, since the switching valve is not operated one by one as in the prior art, and there is no special mechanism for replenishing the cleaning liquid one by one, the structure becomes simple and versatility is improved.

Further, the upper Symbol vessel, equipped with an umbrella-like trap which said one end while expanding from one end to the other end other end located in the upper portion of the container is located inside the vicinity of the container, A communication passage communicating from the upper side to the lower side of the trap is formed at the other end side of the trap, and the upper opening of the discharge pipe portion is positioned at a position higher than the communication passage inside the trap. ing.

  As a result, the cleaning liquid and the sewage pass through the communication path along the outer surface of the trap, and the cleaning liquid accumulates under the container, while the sewage accumulates on the cleaning liquid and is discharged from the upper opening of the discharge pipe. . At this time, since the cleaning liquid and the sewage are received by the trap, a situation in which the cleaning liquid and the sewage are drastically dropped and stirred in the sewage and the cleaning liquid in the container is prevented, so that the cleaning liquid and the sewage are easily separated. In addition, when there is no trap, the mixture of cleaning liquid and sewage immediately reaches the position of the upper opening, so that the cleaning liquid is not separated sufficiently and is discharged from the upper opening in a state where the cleaning liquid is mixed in the sewage. However, since the upper opening is positioned higher than the communication path by providing a trap, the distance from the communication path to the upper opening even if the cleaning liquid and sewage pass through the communication path in a mixed state. Therefore, the cleaning liquid and the sewage can be separated from each other, so that the separation is ensured, and the situation where the sewage is discharged from the upper opening while the cleaning liquid is mixed is prevented.

  Further, if necessary, the container and the discharge pipe part are formed in a cylindrical shape, and the container and the discharge pipe part are arranged with their respective axes coaxial. The deviation of the inflow of sewage and cleaning liquid is prevented, and the sewage can be discharged reliably.

  Furthermore, if necessary, an opening that is provided at the lower part of the container and is allowed to flow into the cleaning liquid that has accumulated in the lower part of the container and separated and subsided from the sewage, and a position that is provided outside the container and is higher than the one end opening. A cleaning liquid discharge path having an opening at the other end, and a cleaning liquid storage tank in which the cleaning liquid flowing out from the other end opening of the cleaning liquid discharge path is stored, and the cleaning liquid stored in the cleaning liquid storage tank is sucked by the pump. Are collected.

According to this, the cleaning liquid collected at the bottom of the container is stored in the cleaning liquid storage tank via the cleaning liquid discharge path. At this time, since the cleaning liquid is non-hydrophilic and has a higher specific gravity than the sewage, the cleaning liquid that has flowed into the container flows into the cleaning liquid discharge path from the one end opening of the cleaning liquid discharge path and flows out from the other end opening with almost no sewage mixed therein. It accumulates in the cleaning liquid storage tank. Then, the cleaning liquid in the cleaning liquid storage tank is sucked and circulated by the operation of the pump.
At this time, only the increment of the cleaning liquid flows out from the container to the cleaning liquid storage tank by the cleaning liquid discharge path, and the amount of the cleaning liquid in the container is stabilized as compared with the case where the cleaning liquid in the container is directly sucked by the pump. Therefore, the liquid level of the cleaning liquid and sewage in the container is prevented from rising and falling by suction of the pump, and the increment of the sewage can be stably discharged from the upper opening of the discharge pipe portion.

  In addition, if necessary, the cleaning liquid storage tank is provided below the container, and the cleaning liquid storage tank is made to penetrate the discharge pipe section, and the lower opening of the discharge pipe section is below the cleaning liquid storage tank. Located in the discharge pipe section, the liquid is mixed with the cleaning liquid flowing out from the cleaning liquid discharge path in the vicinity of the upper surface in the cleaning liquid storage tank, and flows into the cleaning liquid storage tank and is separated from the cleaning liquid in the cleaning liquid storage tank and floats. There is a medium opening through which the sewage is discharged.

  When the operation of the pump ends and the cleaning liquid circulated in the cleaning liquid storage tank accumulates again, the liquid level of the cleaning liquid is positioned near the middle opening in the cleaning liquid storage tank. At this time, a slight amount of sewage mixed in the cleaning liquid flowing in from the cleaning liquid discharge path floats on the cleaning liquid accumulated in the cleaning liquid storage tank, and this floating sewage is discharged from the central opening of the discharge pipe section. Therefore, even if the sewage is mixed slightly into the cleaning liquid and flows into the cleaning liquid storage tank, the sewage can be separated from the cleaning liquid also in the cleaning liquid storage tank. As a result, it is possible to reliably prevent contamination of the cleaning liquid with sewage.

If necessary, a discharge drain for discharging the sewage and the cleaning liquid in the container to the cleaning liquid storage tank side and a plug for closing the discharge drain are provided at the lower part of the container.
When cleaning the inside of the container, the plug of the discharge drain is removed. In this case, first, the cleaning liquid remaining in the container falls into the cleaning liquid storage tank, and the sewage remaining in the container, water used for cleaning, and a water-soluble detergent flow into the cleaning liquid storage tank. In this case, the sewage, water, and water-soluble detergent that have flowed into the cleaning liquid storage tank are discharged from the middle opening, and the cleaning liquid is stored in the cleaning liquid storage tank. Therefore, the inside of the container can be cleaned with almost no cleaning liquid discharged to the discharge pipe portion.

  If necessary, the container, the discharge pipe section, and the cleaning liquid storage tank are formed in a cylindrical shape, and the container, the discharge pipe section, and the cleaning liquid storage tank are arranged coaxially with their axes. The deviation of the inflow of sewage and cleaning liquid is prevented, and the sewage can be discharged reliably.

Further, if necessary, the container comprises a large diameter portion on the upper surface side and a small diameter portion communicating with the large diameter portion via a step portion, and the small diameter portion is inserted into the cleaning liquid storage tank, The opening of the cleaning liquid storage tank is detachably attached to the stepped portion, and the other end opening side of the cleaning liquid discharge path is positioned between the outer side surface of the small diameter portion and the inner side surface of the cleaning liquid storage tank.
Since the storage space for the cleaning liquid discharge path can be secured, the apparatus can be made compact.

  Moreover, the said washing | cleaning liquid discharge path is comprised with the U-shaped pipe | tube with the other end opening located in the outer side of this container and the one end opening provided in the bottom face of the said container as needed. The position of the other end opening can be easily adjusted by adjusting the length.

In addition, if necessary, the discharge pipe section is configured to be detachably connected to each other and includes an upper discharge pipe on the container side and a lower discharge pipe on the cleaning liquid storage tank side.
If the upper discharge pipe is removed when cleaning the inside of the container, sewage or the like in the container can be discharged through the discharge pipe portion, and the inside of the container can be easily cleaned.

Moreover, if necessary, a blocking liquid for blocking odor that is smaller in specific gravity than sewage and can be phase separated is placed outside the trap.
In the container, since the specific gravity of the blocking liquid is smaller than that of sewage, it floats on the sewage to prevent odor. Therefore, it is possible to prevent the odor of sewage from leaking around the toilet bowl.

  According to the urinal apparatus of the present invention, the cleaning liquid can be collected and circulated with a pump, and the structure can be simplified, and the cleaning liquid has a specific gravity greater than that of sewage and can be phase separated. The cleaning liquid and the sewage can be separated in the container, so that the cleaning liquid can hardly be mixed into the sewage, and the discharge amount of the sewage can be reduced. In addition, since the waste water can be separated from the waste water so that the waste water is hardly mixed with the waste water, the frequency of replenishment of the wash liquid can be reduced, and it is not necessary to store a large amount of wash liquid for replenishment, thereby improving management efficiency. be able to. In addition, since there is no need for a special mechanism for replenishing the cleaning liquid one by one, the structure becomes simple and versatility can be improved.

In the upper discharge pipe 43, the upper end opening 45 communicates with the toilet 10, while the lower end opening 49 is fitted in a fitting portion 29 provided in the container 20, and is provided from the upper surface to the bottom surface of the container 20.
The upper end opening 45 of the upper discharge pipe 43 is normally covered and closed by a lid 46.
As shown in FIGS. 2 and 4, a plurality of upper openings 41 along the outer periphery of the upper discharge pipe 43 are provided at the upper portion of the upper discharge pipe 43. The upper opening 41 is positioned inside the trap 50 and at a position higher than a communication path 51 of the trap 50 described later. Further, an O-ring 47 that seals the outer surface of the upper discharge pipe 43 and the container 20 is provided at a portion that is fitted to the lower fitting portion 29 of the upper discharge pipe 43.

The lower discharge pipe 44 is provided from the upper surface to the lower surface of the cleaning liquid storage tank 35.
The lower discharge pipe 44 is provided in the vicinity of the upper surface in the cleaning liquid storage tank 35 and flows into the cleaning liquid storage tank 35 mixed with the cleaning liquid L flowing out from the U-shaped tube 30a and floats separately from the cleaning liquid L in the cleaning liquid storage tank 35.

The urinal device S includes a pump 60 that sucks and collects the cleaning liquid L separated from the sewage F in the container 20 and sinks, and a feeding unit that flows the cleaning liquid L collected by the pump 60 to the toilet 10. 65.
The pump 60 sinks and accumulates in the lower part of the container 20 and collects the cleaning liquid L stored in the cleaning liquid storage tank 35 by sucking the U-shaped pipe 30a through the recovery pipe 61 provided at the bottom of the cleaning liquid storage tank 35. is doing.
The feeding unit 65 includes a feeding pipe 66 that communicates between the pump 60 and the upper part of the toilet 10, and is configured to directly flow the cleaning liquid L collected by the pump 60 into the toilet 10.

Furthermore, the urinal device S is provided with a detection sensor 71 that detects the presence or absence of the user of the toilet 10, and a control means 70 that operates the pump 60 based on the detection of the detection sensor 71. Yes. The urinal apparatus S performs the control described below by the control means 70.
In FIG. 1, reference numeral 12 denotes a mesh-like mesh for receiving foreign matter such as dust flowing through the toilet 10.

When using the urinal device S configured as described above, first, a cleaning liquid layer, a sewage layer, and a blocking liquid layer are formed in the container 20 in advance. Specifically, as shown in FIG. 5A, first, a predetermined amount of the cleaning liquid L is caused to flow into the container 20 to form a cleaning liquid layer at the bottom of the container 20, and the cleaning liquid L is allowed to flow out from the U-shaped tube 30a. Then, the cleaning liquid storage tank 35 is filled with the cleaning liquid L. In this state, as shown in FIG. 5B, water is put in place of the sewage F to form a sewage layer inside the container 20. When the water as the sewage F is poured, it floats and accumulates on the cleaning liquid layer, forms a sewage layer and pushes the cleaning liquid layer. At this time, the cleaning liquid L of the cleaning liquid layer flows into the cleaning liquid storage tank 35 as needed from the other end opening 32 of the U-shaped tube 30a.
In this way, water as sewage F is poured into the container 20 until the liquid level of the sewage layer reaches the upper opening 41. The water as the sewage F reaching the upper opening 41 is sequentially flowed from the upper opening 41 to the sewage through the discharge pipe portion 40. Next, as shown in FIG. 5C, a predetermined amount of the blocking liquid 52 is put outside the trap 50 in the container 20, and a blocking liquid layer is formed on the sewage layer outside the trap 50.

Next, the case where the urinal apparatus S which concerns on embodiment of this invention is used is demonstrated. As shown in FIG. 6 (a), normally, the container 20 has a blocking liquid layer formed outside the trap 50, and outside the trap 50 and below the blocking liquid layer and inside the trap 50. A sewage layer whose liquid level is located in the upper opening 41 and a cleaning liquid layer below the sewage layer are formed. Further, in the cleaning liquid storage tank 35, the liquid level of the cleaning liquid storage tank 35 is positioned near the middle opening 48.
If it demonstrates based on control of the control means 70, with reference to the flowchart shown in FIG. 7, the control means 70 will operate | move when the urinal apparatus S is first turned on (1-1). In this state, the detection sensor 71 is checked (1-2), and the detection sensor 71 is continuously checked until it is detected that the user is present (1-3N). Next, when the detection sensor 71 detects the presence of the user (1-3Y), the pump 60 is turned on to draw the cleaning liquid L in the cleaning liquid storage tank 35 from the recovery pipe 61 and through the feed pipe 66. The pumped washing liquid L is allowed to flow from the upper part of the toilet 10 (1-4).

When the detection sensor 71 continues to detect the state where the user stands in front of the toilet bowl 10 (1-5), the pump 60 is turned on (1-6Y).
When the cleaning liquid L flows into the toilet 10, as shown in FIG. 6 (b), the cleaning liquid L in the cleaning liquid storage tank 35 decreases, while the cleaning liquid L flows down from the toilet 10 and flows into the container 20 from the discharge port 11. Come on.
The cleaning liquid L that has flowed into the container 20 is received by the trap 50, flows on the outer surface thereof, and passes through the communication path 51. Since the cleaning liquid L is non-hydrophilic and has a higher specific gravity than the sewage F, the cleaning liquid L that has flowed into the container 20 flows into the U-shaped pipe 30a from the one end opening 31 of the U-shaped pipe 30a with almost no sewage F mixed therein. The cleaning liquid L flows out from the other end opening 32 and accumulates in the cleaning liquid storage tank 35.
At this time, since a plurality of U-shaped tubes 30a are arranged, the inflow of the cleaning liquid L from the one end opening 31 of the U-shaped tube 30a and the outflow of the cleaning liquid L from the other end opening 32 of the U-shaped tube 30a are sufficiently performed. It is.

Next, when the sewage F flows into the toilet 10, the sewage F is discharged from the discharge port 11 and flows into the container 20 together with the cleaning liquid L from the inlet 21 as shown in FIG. The cleaning liquid L and the sewage F pass through the communication path 51 along the outer surface of the trap 50.
The sewage F has a specific gravity greater than that of the blocking liquid 52 and is lower than that of the cleaning liquid L. Therefore, the sewage F passes through the blocking liquid layer, reaches the sewage layer in the container 20 and mixes with the sewage layer. Separates and floats on the cleaning liquid layer. As in the case of flowing into the container 20 described above, the cleaning liquid L is separated from the sewage F and collected at the bottom of the container 20 and mixed with the cleaning liquid layer. In the container 20, the sewage F collected on the cleaning liquid layer flows out from the upper opening 41 of the discharge pipe section 40 due to the rise in the liquid level of the sewage layer and is discharged into the sewage. The cleaning liquid L collected at the bottom flows out into the cleaning liquid storage tank 35 as in the case where only the cleaning liquid L flows.

In this case, since the upper openings 41 of the discharge pipe portion 40 are provided in a plurality of rows along the outer periphery of the discharge pipe, even if a large amount of the sewage F temporarily flows, it can be discharged without delay.
In this case, since the cleaning liquid L is non-hydrophilic and has a higher specific gravity than the sewage F, the cleaning liquid L and the sewage F are well separated in the container 20, and therefore the cleaning liquid L can hardly be mixed into the sewage F. Therefore, the discharge amount of the sewage F can be reduced as compared with the conventional case. Further, since the cleaning liquid L is a fluorine-inactive liquid, it has excellent phase separation from the sewage F. In this respect, the cleaning liquid L can hardly be mixed into the sewage F, and the discharge amount of the sewage F can be reduced. .

  At this time, since the cleaning liquid L and the sewage F are received by the trap 50, a situation where the sewage F and the cleaning liquid L in the container 20 are violently dropped and stirred is prevented, so that the cleaning liquid L and the sewage F are separated. Is easily done. In addition, when there is no trap 50, the mixture of the cleaning liquid L and the sewage F immediately reaches the position where the upper opening 41 is located, so that the cleaning liquid L is mixed into the sewage F without being sufficiently separated. However, since the trap 50 is provided and the upper opening 41 is positioned higher than the communication path 51, the cleaning liquid L and the sewage F are mixed in the communication path. Even after passing through 51, the cleaning liquid L and the sewage F can be separated from each other by the distance from the communication path 51 to the upper opening 41, and as a result, separation is ensured and the upper opening 41 remains mixed with the cleaning liquid L. The situation where the sewage F is discharged from is prevented.

During this time, the cleaning liquid L in the cleaning liquid storage tank 35 is sequentially sucked and circulated from the recovery pipe 61 by the operation of the pump 60, while the cleaning liquid L in the container 20 collected at the bottom of the container 20 is U The liquid is stored in the cleaning liquid storage tank 35 through the character tube 30a.
At this time, as compared with the case where the cleaning liquid L is sucked directly from the container 20 by the pump 60, only the increment of the cleaning liquid L flows out from the container 20 to the cleaning liquid storage tank 35 through the U-shaped tube 30a. Since the amount of L is stabilized, the liquid level of the cleaning liquid L and the sewage F in the container 20 is prevented from rising and falling in the container 20 by suction of the pump 60, and the increment of the sewage F is stably discharged. It can be discharged from the upper opening 41 of the path portion 40.

Further, at this time, a slight amount of sewage F mixed with the cleaning liquid L that cannot be separated in the container 20 is accumulated on the cleaning liquid layer of the cleaning liquid storage tank 35.
When the user leaves and the detection sensor 71 no longer detects the presence of the user (1-5, 1-6N), the pump 60 is stopped after a predetermined time (1-7Y) (1-8). On the other hand, before the predetermined time elapses, the detection sensor 71 is checked (1-9), and if there is a user of the toilet 10, the pump 60 is left on (1-10Y, 1-4).
When the pump 60 is stopped and the cleaning liquid L does not flow, the liquid level of the sewage F in the container 20 returns to the vicinity of the upper opening 41 of the discharge pipe section 40 again as shown in FIG.
At this time, when the circulated cleaning liquid L accumulates again in the cleaning liquid storage tank 35, the surface of the cleaning liquid L is positioned near the inner opening 48 in the cleaning liquid storage tank 35. At this time, the slight sewage F mixed in the cleaning liquid L flowing in from the U-shaped pipe 30 a floats on the cleaning liquid L collected in the cleaning liquid storage tank 35. It is discharged from the opening 48. Therefore, even if the sewage F is slightly mixed into the cleaning liquid L and flows into the cleaning liquid storage tank 35, the sewage F and the cleaning liquid L can be separated also in the cleaning liquid storage tank 35. Thus, the wastewater F is discharged twice, and the contamination of the wastewater F into the cleaning liquid L can be reliably prevented.

Then, it waits until the next user comes (1-2, 1-3N).
In the standby state, since the blocking liquid layer is on the sewage layer, the odor of the sewage F is stopped by the blocking liquid layer, so that the odor is surely stopped and the odor is discharged from the outlet 11 around the toilet 10. It is possible to prevent leakage and contamination of the surrounding environment.
In this way, cleaning with the cleaning liquid L is performed. In this cleaning, the cleaning liquid L is slightly mixed with the sewage F and consumed, but the consumed amount may be appropriately supplemented. What is necessary is just to put the washing | cleaning liquid L from the toilet bowl 10 in the case of replenishment. In this case, since the consumption of the cleaning liquid L is extremely small, the replenishment frequency of the cleaning liquid L is greatly reduced as compared with the conventional case, and the management efficiency is improved.
Further, since the switching valve is not operated one by one as in the prior art and there is no special mechanism for replenishing the cleaning liquid L one by one, the structure becomes simple and versatility is improved.

Next, cleaning of the urinal apparatus S will be described. Cleaning is periodically performed so that the cleaning liquid L is replaced when the cleaning liquid L is deteriorated, and urinary stones that are sources of odor are not generated in the toilet bowl 10 and the container 20.
When the toilet bowl 10 is washed, the lid 46 is removed and the discharge port 11 is appropriately closed, and the inside of the container 20 is washed with a detergent or the like for cleaning. The detergent does not affect the cleaning liquid L because it flows directly to the discharge pipe section 40.

When cleaning the container 20, the bottom part of the toilet 10 and the mesh 12 are removed, and the upper discharge pipe 43 is taken out from the container 20, and the blocking liquid 52 and the sewage F in the container 20 are discharged from the discharge pipe part 40. Shed. Next, a hook is hooked on the hole 26a of the plug 26 of the discharge drain 25, the plug 26 is removed, and the sewage F and the cleaning liquid L remaining in the container 20 are flowed to the cleaning liquid storage tank 35 side.
At this time, on the cleaning liquid storage tank 35 side, the cleaning liquid L is mixed in the cleaning liquid layer of the cleaning liquid storage tank 35, while the sewage F floats on the cleaning liquid L and is discharged from the middle opening 48.
Then, the container 20 and the cleaning liquid storage tank 35 are cleaned.
At this time, the water to be used and the detergent dissolved in the water flow into the cleaning liquid storage tank 35, but the water and the detergent dissolved in the water flowing into the cleaning liquid storage tank 35 are more specific than the cleaning liquid L. Is light, and is discharged from the middle opening 48. Therefore, cleaning can be performed easily.
Thereafter, the plug 26, the upper discharge pipe 43, the mesh 12, the bottom surface of the toilet 10, and the lid 46 are returned to the original state.

Thereby, it is not necessary to pump out the sewage F and the cleaning liquid L in the container 20, and the inside of the container 20 can be easily cleaned. At this time, since the cleaning liquid L in the cleaning liquid storage tank 35 is hardly flowed, the cleaning liquid L can be saved.
When the urinal device S is used again, as described above, the cleaning liquid L, the water as the sewage F, and the blocking liquid 52 are allowed to flow into the container 20 from the outlet 11 of the toilet 10 and wait.

8 to 10 show a main part of a urinal apparatus S according to another embodiment of the present invention. The urinal apparatus S has a configuration substantially similar to that of the above embodiment, but the cleaning liquid discharge path 30 is different from that of the above embodiment.
Specifically, the bottom surface 20 a of the container 20 is positioned at a predetermined distance from the lower side edge of the container 20. A bottom surface 20 a of the container 20 is provided integrally with the discharge pipe portion 40 and extends outward in the circumferential direction of the container 20. Further, on the outer peripheral edge portion of the bottom surface 20a, there is provided a standing portion 33 which stands upward from the bottom surface 20a and is spaced apart from the outer surface of the container 20 by a predetermined distance. An erection member 34 is installed between the inner side surface of the standing portion 33 and the outer side surface of the container 20 in order to hold the bottom surface 20 a on the container 20 via the standing portion 33.
A plurality of the erection members 34 are provided at intervals of 45 °.

The cleaning liquid discharge path 30 is constituted by a gap formed by the inner side surface of the standing portion 33 provided on the bottom surface 20 a of the container 20 and the outer side surface of the container 20.
The cleaning liquid discharge path 30 includes an end opening 31 formed by a gap formed at 360 ° along the circumference of the container 20 between the lower side edge of the container 20 and the bottom surface 20 a, and the upper end of the standing portion 33 of the container 20. And the other end opening 32 formed of a gap formed at equiangular intervals of 45 ° along the circumference of the container 20. Compared with the case where the U-shaped tube 30a is provided, the structure is simplified. Other than this, the configuration is substantially the same as in the above embodiment.

  When using the urinal device S configured as described above, similarly to the above embodiment, first, water as the cleaning liquid L and the sewage F is poured in advance, and the cleaning liquid layer and the sewage layer are placed inside the container 20. Form it. In the urinal apparatus S, normally, a blocking liquid layer formed outside the trap 50 in the container 20 and a lower side of the blocking liquid layer outside the trap 50 and inside the trap 50. A sewage layer whose liquid level is located in the upper opening 41 and a cleaning liquid layer below the sewage layer are formed. Further, in the cleaning liquid storage tank 35, the liquid level of the cleaning liquid storage tank 35 is positioned near the middle opening 48.

When the urinal device S is operated and the cleaning liquid L is poured into the container 20, the cleaning liquid L separates from the sewage F and sinks. Next, when the sewage F is flowed in this state, the sewage F separates from the cleaning liquid L and floats on the cleaning liquid layer in the container 20, while the cleaning liquid L separates from the sewage F in the same manner as described above. It sinks to the bottom of 20. Then, the sewage F is caused to flow from the upper opening 41 to the discharge pipe portion 40 as the liquid level of the sewage F increases. The cleaning liquid L collected at the bottom of the container 20 flows in from the one end opening 31 of the cleaning liquid discharge path 30 and flows out from the other end opening 32, and flows into the cleaning liquid storage tank 35 through the outside of the standing portion 33.
Other functions and effects are the same as those described above.
