Detailed ways

As schematically and schematically shown in FIG. 1 , a circulating flush urinal 1 for men according to an embodiment of the present invention includes a housing 5 with a flush toilet 3 . The housing 5 includes a flush water storage tank 7 for storing an appropriate amount of flush water W for flushing the flush toilet 3 on the lower side inside the casing 5 . The bottom of the flush water storage tank 7 is provided with a flush water collecting portion 9 for collecting the flush water W at one place. In other words, the bottom of the flush water storage tank 7 is suitably inclined so that the flush water collecting portion 9 becomes the lowest.

The bottom of the storage tank 7 is preferably formed in a conical shape such as a cone or a pyramid as a structure for forming the flush water collecting portion 9 , but it may be formed in an appropriate curved surface such as a bowl, for example.

The outflow passage 11 provided at the bottom of the flush toilet 3 is branched into a communication passage 13 communicating with the above-mentioned flushing water storage tank 7 and a drainage passage (drain pipe) 15 connected to a sewer (not shown in the figure). 13 and the branch portion of the drainage channel 15 have a switching valve 17 . The switching valve 17 cuts off the connection between the outflow path 11 and the drainage path 15 when connecting the above-mentioned outflow path 11 to the communication path 13. The role of the connection of the passage 13. The above-mentioned switching valve 17 is configured such that a flap valve, a three-way valve, a rotary valve, etc. are switched by, for example, a rotary actuator, and the switching operation is performed by an appropriate actuator such as a solenoid.

A drain pipe 19 connected to the drain passage 15 is connected to the flush water concentrating portion 9 of the flush water storage tank 7, and a solenoid valve, for example, which can cut off or communicate with the drain pipe 19 is provided on the drain pipe 19. The switching valve 21. The on-off valve 21 is opened when the flush water in the flush water storage tank 7 is discharged. Also, a supply pipe 23 for supplying new flush water into the flush water storage tank 7 after the flush water is discharged by opening the on-off valve 21 is connected, and an on-off valve 25 is provided on the supply pipe 23 .

In order to circulate the flush water stored in the flush water storage tank 7 to flush the flush toilet 3 , a flush water circulation unit 27 is provided in the housing 5 . More specifically, the flush water circulation unit 27 includes a pump 10 that sucks flush water W from the vicinity of the flush water collecting portion 9 of the flush water storage tank 7 , and the discharge side piping 31 of the pump 10 is provided with, for example, a swirler. Wait for such a purification unit 33 . Furthermore, the discharge-side piping 31 is connected to an auxiliary tank 35 provided in the casing 5 .

Furthermore, when circulating flushing water to the water closet 3 by the above-mentioned pump 10, instead of the above-mentioned purification unit 33, a filter or the like is provided on the pipe connected to the suction side of the above-mentioned pump 10, and it is also possible to connect the water from the pump 10 to the water closet. 3. Set the filter on the appropriate position. In addition, when the circulating flushing water is relatively clean, the above-mentioned purification unit 33 can also be omitted.

The above-mentioned auxiliary water tank 35 is a container for temporarily storing the flushing water used to flow to the above-mentioned flushing toilet 3, and the discharge pipe 37 for discharging the flushing water in the auxiliary water tank 35 is connected to the auxiliary water tank 35, and the discharge pipe 37 is equipped with Switch valve 39. Furthermore, an overflow pipe 41 is connected to the auxiliary tank 35 . Furthermore, a pump 43 for flowing flush water in the auxiliary tank 35 into the flush toilet 3 is provided, and a pipe 45 connected to the upper side of the flush toilet 3 is provided.

In addition, the structure which directly connects the said discharge side piping 31 and the said piping 45 is also possible, and in this case, the said auxiliary tank 35, the pump 43, etc. can also be omitted.

The casing 5 is equipped with a suitable human body detection unit 47 composed of a proximity sensor such as an ultrasonic sensor, and a control device 49 for controlling various drivers is provided at a suitable position. The control device 49 controls switching of the switching valve 17 in order to connect the outflow path 11 and the drainage path 15 of the flush toilet 3 when the human body detection unit 47 detects a person using (using) the flush toilet 3 . And, when it is detected by the above-mentioned human body detection unit 47 that the user (user) has finished using the flush toilet 3 (leaved), the control device 49 drives the pump 10 to flush the above-mentioned flush toilet 3, or drives the pump 43 to make the flush water It flows into the flush toilet 3, and at the same time, the switching operation of the switching valve 17 is controlled in order to connect the outflow path 11 and the communication path 13. That is, the control device 49 is a device that controls various operations of the circulating flush urinal 1 as described later.

In the above structure, when a user (user) approaches the casing 5 to use the flush toilet 3, the human body detection means 47 detects the user. At this time, since the switching valve 17 is in a state of connecting the outflow path 11 and the drain path 15 , the user's urine (urine) is discharged to a sewer or the like through the drain path 15 . And, when it is detected by the human body detection unit 47 etc. that the user has left the housing 5 or finished using it, the pump 43 is driven for a predetermined time to allow a predetermined amount of flushing water to flow into the flush toilet 3 to flush the flush toilet 3. The switching valve 17 is switched by bringing the outflow path 11 and the communication path 13 into a connected state.

Therefore, the flush water after flushing the flush toilet 3 is recycled into the flush water storage tank 7 . At this time, most of the user's urine is discharged to the side of the drainage channel 15, and the flush water flushes the flush water toilet 3 by washing away a small amount of urine attached to the surface of the flush toilet 3, so that it is recycled into the flush water storage tank. There is very little dirty water (urine) in 7. Therefore, the amount of contamination of the flushing water in the flushing water storage tank 7 greatly lags behind that in the case where all the urine flows into the flushing water storage tank 7 . In other words, the rinse water remains relatively clean for a long time.

Therefore, the frequency of replacing the flushing water due to the amount of flushing water contamination in the flushing water storage tank 7 is reduced, and the water saving effect is improved. In addition, when washing the urinal with flushing water, there are also situations where an appropriate amount of purification liquid "such as TRIEX-1 (trade name)" is added to the flushing water, but the amount of the above purification liquid can be reduced, and the addition of the above-mentioned purification liquid can also be omitted depending on the situation. Purifying fluid. Furthermore, since the amount of dirty water recovered into the flush water storage tank 7 is small, the volume of the flush water storage tank 7 can be reduced, and the overall structure can be downsized.

As mentioned above, after the flushing water flows into the toilet 3 for flushing, when the predetermined time preset by the timer switch (not shown) passes, under the control of the control device 49, the switching valve 17 returns to the initial state, that is, The state of connecting the outflow path 11 and the drainage path 15. However, if there is concern about the occurrence of unpleasant gas in the communication passage 13 or the drainage passage 15, it is preferable to keep the connection between the above-mentioned outflow passage 11, the communication passage 13 and the drainage passage 15 through the switching valve 17 in a normal state. cut off state.

As mentioned above, by driving the pump 43, the flushing water in the auxiliary tank 35 flows into the flush toilet 3 for flushing. When the flushing water in the auxiliary tank 35 is detected by a suitable water level sensor (not shown) When decreasing, the pump 10 is driven under the control of the control device 49 to supplement the flushing water in the flushing water storage tank 7 into the auxiliary water tank 35 . At this time, the flushing water flowing into the auxiliary tank 35 passes through a purification unit 33 such as an appropriate filter or a cyclone to remove minute solids and the like.

As mentioned above, by circulating the flushing water in the above-mentioned flushing water storage tank 7, the flushing toilet 3 is repeatedly flushed, and when the flushing urinal 1 is not in use, or when a predetermined time is reached, the on-off valves 21, 39 are opened. Action, the flushing water in the flushing water storage tank 7 and the auxiliary water tank 35 is discharged to the drainage channel 15 . The predetermined time can be detected by comparing the time (for example, 22:00) set in advance in the memory of the control device 49 with the time of the clock installed in the control device 49 . In addition, when the flush urinal 1 is not in use, even before the above-mentioned predetermined time, the light sensor (not shown) detects that the lighting of the installation place of the flush urinal 1 is turned off, for example, or by detecting that the light is not in use. Quantitative conditions (such as setting the conditions that the door of the building is locked and no one is in the building, etc.) can also be detected.

As described above, when the flushing water in the flushing water storage tank 7 is discharged, the flushing water collecting part 9 is formed at the bottom of the flushing water storage tank 7, and the bottom is inclined so that the flushing water collecting part 9 is the lowest. The sediment that tends to stagnate at the bottom of the flush water storage tank 7 is discharged down to the flush water collecting portion 9 . Therefore, sediment does not remain at the bottom of the flushing water storage tank 7, and it is possible to prevent the occurrence of an unpleasant smell due to the accumulation of sediment.

As described above, after the flush water is discharged from the flush water storage tank 7 and the auxiliary tank 35, the on-off valves 21 and 39 are closed, and the on-off valve 25 is opened to supply new flush water to the flush water storage tank 7. The flushing water drives the pump 10 to supply new flushing water to the auxiliary tank 35, whereby the flushing water storage tank 7 and the auxiliary tank 35 can become the initial state of storing new flushing water.

Furthermore, when new flush water is stored in the flush water storage tank 7 and the auxiliary water tank 35, it is also possible to flush the flush water storage tank 7 and the auxiliary water tank 35 once with new flush water, and then store new flush water again. of rinse water.

As will be further understood from the above description, the flushing of the flush toilet 3 is carried out by recycling the flush water recovered from the flush water storage tank 7, and most of the urine of the user of the flush toilet 3 is discharged to the drain pipe 15. , flush the urine attached to the flush toilet 3, therefore, the aggravation of the pollution degree of the flush water recovered by the flush water storage tank 7 lags behind, and the number of flush water discharged from the flush water storage tank 7 depends on the number of users. The ratio becomes smaller, and a greater water-saving effect is achieved.

However, in order to more effectively prevent the unpleasant smell of the flushing water in the above-mentioned flushing water storage tank 7 and the auxiliary water tank 35 from leaking to the outside, the flushing water storage tank 7 and the auxiliary water tank 35 are preferably made not to leak to the outside under normal conditions. The airtight structure prevents unpleasant gas from leaking out. In this case, for example, the following configuration is possible. Furthermore, the structure of the auxiliary water tank 35 can be made as a structure based on the flush water storage tank 7, therefore, the situation of the flush water storage tank 7 is exemplified, and the constituent elements of the above-mentioned embodiment have the same function as that of the flush water storage tank 7. The constituent elements are marked with the same symbols and repeated explanations are omitted.

FIG. 2 is a diagram schematically and schematically showing the flush water storage tank 7 in a sealed state. In this embodiment, a check valve 51 is provided on the upper portion of the flush water storage tank 7 for allowing the inflow of outside air to the flush water storage tank 7 but preventing the outflow of air from the flush water storage tank 7 . Furthermore, the valve body 53 provided on the check valve 51 is an actuator 57 capable of pushing against the urging force of the coil spring 55 . The actuator 57 may be any element as long as it can push the valve body 53 and open the check valve 51 when necessary, and may be a solenoid, for example.

In this example, a fluid pressure cylinder 61 in which a piston 59 is reciprocally attached is exemplified as the above-mentioned actuator 57 . The piston 59 has a piston rod 63 capable of pressing the valve body 53 with its front end. And, in the fluid pressure chamber of the piston rod side of the above-mentioned fluid pressure cylinder 61, a coil spring 65 elastically pressing the above-mentioned piston rod 63 to the direction away from the above-mentioned valve body 53 is elastically installed, and the fluid on the piston side of the above-mentioned fluid pressure cylinder 61 The pressure chamber communicates with the inside of the flush storage tank 7 through the communication hole 67 .

With the above-mentioned structure, the flushing water W in the flushing water storage tank 7 is sucked by the filter through the drive of the pump 10, and when negative pressure is generated inside, the valve body 53 will move toward the valve body 53 against the force of the coil spring 55 of the check valve 51. Moving in the inner direction, the check valve 51 is opened and the outside air is sucked in. Similarly, when the on-off valve 21 is opened to discharge the flush water inside, the outside air is also sucked in from the check valve 51 . That is, suction or discharge of the flush water W in the flush water storage tank 7 can be performed without any problem.

Furthermore, some pressure changes in the flush water storage tank 7 in a sealed state are absorbed by the upper air layer, so that no major problem arises.

When the on-off valve 25 is opened to supply new flush water from the supply pipe 23 to the flush water storage tank 7, the pressure in the flush water storage tank 7 is gradually increased by the supply of flush water. The pressure in the flushing water storage tank 7 acts on the fluid pressure chamber on the piston side of the fluid pressure cylinder 61, and overcomes the force of the coil spring 65 to push the piston 59, so the piston rod 63 pushes the valve body 53 of the check valve 51, The check valve 51 is in an open state. Therefore, the gas in the flush water storage tank 7 flows out to the outside through the check valve 51, so that the flush water storage tank 7 can be replenished with new flush water without any problem.

As already understood, in a normal state, since the check valve 51 is in a closed state, the gas in the flushing water storage tank 7 can be prevented from flowing out to the outside in a normal state. Furthermore, in such a sealed structure, the bottom of the flushing water storage tank 7 may also be made flat.

However, the present invention is not limited to the above configuration, and may be implemented in other forms by making appropriate changes. For example, instead of the on-off valve 21, an on-off valve capable of opening and closing the opening of the drain pipe 19 may be provided at the connection between the bottom of the flush water storage tank 7 and the drain pipe 19. In addition, the on-off valve 39 also has the same structure.

In addition, it is also possible to arrange the supply pipe 23 at a height corresponding to the auxiliary tank 35 or near the end of the piping 45 so as to supply new flushing water from the auxiliary tank 35 side to the flushing water storage tank 7 side or from The flush toilet 3 side supplies new flush water to the flush water storage tank 7 side.

In addition, each time the flush water is discharged from the flush water storage tank 7, it may be configured to discharge the flush water to the drain passage 15 at a high position using a pump as necessary. Furthermore, like a normal flush urinal, a discharge anti-air valve may be provided at an appropriate portion such as the portion of the above-mentioned outflow path 11 . That is, various changes are possible as a design.
