  Here, as shown in FIG. 1, in the toilet system 10 of the present embodiment, a circulation channel 60 of the conveyance water flowing through each floor FL is formed. Specifically, the circulation channel 60 is formed by three channel systems, a first system 61, a second system 62, and a third system 63.

  The first system 61 is formed by the first storage tank 16, the transport water supply pipe 22A, and the drainage horizontal pipe 13A. That is, in the first system 61, the transport water is supplied into the first storage tank 16 from the downstream portion 132A of the drainage horizontal pipe 13A. The second system 62 is formed by the first storage tank 16, the transport water supply pipe 22 </ b> B, the drainage horizontal pipe 13 </ b> B, and the drainage vertical pipe 14. The third system 63 is formed by the first storage tank 16, the conveyance water supply pipe 22 </ b> C, the drainage horizontal pipe 13 </ b> C, and the drainage vertical pipe 14. A first pump 21A is arranged in the first system 61, a second pump 21B is arranged in the second system 62, and a third pump 21C is arranged in the third system 63. Thereby, the conveyance water circulates in the circulation flow path 60 of each system.

  Next, the supply operation of the conveyance water by the toilet system 10 of this embodiment is demonstrated. FIG. 2 is a time chart of the conveyance water supply control in the toilet system 10 according to the present embodiment. This conveyance water supply control is executed by the control unit 70. In the present embodiment, each pump is operated under the following operating conditions, for example.

[Operating conditions of each pump]
Supply amount of transport water: 180 L / time Operation time (t11 to t12, t21 to t22, t31 to t32): 40 seconds Operation interval between pumps (t12 to t21, t22 to t31, t32 to t11): 120 seconds

When the above operating conditions are input to the control unit 70, the operation of the first pump 21A is started.
The controller 70 causes the first pump 21A to pump a predetermined amount of transport water from the first storage tank 16 to the transport water supply pipe 22A. Thereby, the conveyance water is collected in the first storage tank 16 together with the discharge discharged into the drainage horizontal pipe 13. Accordingly, the transport water circulates through the first system 61.

  Subsequently, after the operation by the first pump 21A is completed, the operation of supplying the transport water to the second system 62 by the second pump 21B is started. By the operation of the second pump 21 </ b> B, the conveyance water pumped into the second system 62 circulates through the second system 62 and is collected in the first storage tank 16 together with the discharge.

  Similarly, after the operation by the second pump 21B is completed, the operation of supplying the transport water to the third system 63 by the third pump 21C is started. By the operation of the third pump 21C, the transport water pumped into the third system 63 circulates through the third system 63 and is collected in the first storage tank 16 together with the discharge.

  After the operation by the third pump 21C is finished, the operation of supplying the transport water to the first system 61 by the first pump 21A is started again.

  As described above, a predetermined amount of transport water can be supplied to each system by shifting the operation timing of each pump. Thereby, the discharge in the circulation channel 60 can be conveyed with conveyance water. As a result, it is not necessary to start each pump at a time, and the power peak can be minimized.

  In addition, since the transport water is always stored in the first storage tank 16 at the start of the operation of each pump, the capacity of the first storage tank 16 can be minimized. For example, when the discharge in the circulation channel 60 can be transported with 90 L of transport water, a capacity of 90 L is used.

  In addition, the operating condition of the transfer pump 21 is changed so as to increase the number of transfer water supply control operations during the day when the use frequency of the toilet is high, and on the other hand at night when the use frequency of the toilet is low. You may change so that a conveyance water supply control operation may be stopped.

Then, the replacement | exchange operation | movement of the conveyance water by the toilet system 10 is demonstrated.
First, the water quality in the 1st storage tank 16 deteriorates gradually by circulation of conveyance water. Therefore, a control signal is transmitted to the control unit 70 when the amount of suspended solids in the first storage tank 16 exceeds a threshold by a water quality sensor (not shown) installed in the first storage tank 16.
Thereby, the replacement | exchange operation | movement of the conveyance water in the 1st storage tank 16 by the replacement part 30 is started.

  After starting the operation of the replacement unit 30, the transport water in the second storage tank 17 is supplied into the first storage tank 16 by the replacement pump 31. Thereby, the conveyance water containing a lot of suspended matters etc. is drained from the drain pipe 15 to the sewer pipe. Then, when it is confirmed that the water quality in the 1st storage tank 16 became below the predetermined value, the replacement | exchange operation | movement of the conveyance water by the replacement part 30 is complete | finished.

  Note that the monitoring target of the water quality sensor in the first storage tank 16 can be appropriately changed to the BOD (Biochemical Oxygen demand) of the transport water, the hydrogen sulfide concentration, or the like.

  In addition, the operation condition of the replacement unit 30 is to change the operation setting so that, for example, after a predetermined time has elapsed, all of the transport water in the first storage tank 16 is replaced with the water in the second storage tank 17. Is also possible.

Subsequently, a storage operation by the emergency discharge unit 40 at the time of a disaster or the like will be described.
In the event of a disaster, drainage of sewage such as transport water is restricted. Therefore, the on-off valve 41 provided in the middle of the emergency discharge pipe 42 is manually opened. When the transport water in the first storage tank 16 exceeds a predetermined amount, it is guided from the emergency discharge pipe 42 to the third storage tank. Thereby, even at the time of a disaster, the inside of the 1st storage tank 16 does not become full, but it becomes possible to keep the discharge | emission and filth from each toilet bowl in the 1st storage tank 16. FIG.

  According to the toilet system 10 according to the present embodiment described above, the following effects are produced.

In the toilet system 10 according to the present embodiment, a plurality of toilets 11 are arranged on each floor FL of the building 1 and are inclined downward from the upstream side to the downstream side on each floor FL of the building 1.

It was set as the structure provided with.
More specifically, according to the present embodiment, the first storage tank 16 is disposed in the first underground space 4A, and the transport water in the first storage tank 16 is drained from each floor by the transport pump 21 and the transport water supply pipe 22. By supplying the upstream portion 131 of the horizontal pipe 13, the waste flowing through the drainage horizontal pipe 13 on each floor can be conveyed without staying. Therefore, according to the present embodiment, it is possible to provide a toilet system 10 capable of transporting discharges without providing fluid ejection means on each floor of a multi-story building as in the prior art.
Usually, facilities such as drainage pits are often provided under the floor of the lowermost floor 1F, and it is easy to secure a storage space for the storage tank, while the floors of the middle floor 2F and the upper floor 3F are below. It is difficult to secure a space where a storage tank can be installed. In this respect, in the present embodiment, since the first storage tank 16 is disposed under the floor of the lowest floor 1F, it is easy to secure an installation space.
Furthermore, in this embodiment, when the toilets of the middle floor 2F and the upper floor 3F are wall-drainage type in which the inclination angle of the drainage horizontal pipe is limited and there is a problem in water saving from the viewpoint of transportability, the drainage horizontal pipe 13 By supplying transport water from the upstream side, a toilet system with a small amount of water used can be realized.

Moreover, in this embodiment, it is further extended in the vertical direction, is further provided with the drainage vertical pipe 14 connected to the downstream part 132 of the drainage horizontal pipe 13 in each floor FL of the building 1, and the drainage vertical pipe in the 1st storage tank 16 14 downstream end portions 141 were connected.
Thereby, the conveyance water which distribute | circulates the waste_water | drain side pipe 13 can be collect | recovered in the 1st storage tank 16. FIG. Therefore, according to this embodiment, the conveyance water which distribute | circulates the inside of the waste_water | drain side pipe 13 can be utilized for conveyance of a discharge again.

Moreover, in this embodiment, the supply part 20 is arrange | positioned on the lowest floor of the building 1 with the some conveyance water supply pipe 22 connected to the upstream part 131 of each drainage horizontal pipe in the at least 1 floor of the building 1. The transport pump 21 that pumps the transport water in the first storage tank 16 to the transport water supply pipe 22 and the control unit 70 that controls the operation of the transport pump 21 are used. Specifically, the first pump 21 </ b> A to the third pump 21 </ b> C and the control unit 70 are collectively arranged in the underground 4.
Thus, according to the present embodiment, even if the first pump 21A to the third pump 21C and the control unit 70 break down, it is not necessary to perform maintenance under the floor as in the conventional case, and maintenance management becomes easy.

In the present embodiment, a plurality of transport pumps 21 are arranged for each transport water supply pipe 22, and the control unit 70 controls the operation by shifting the operation timings of the first pump 21A to the third pump 21C so as not to overlap. It was configured to be. That is, the supply unit 20 supplies the conveyance water in order for each system of the circulation flow path 60, and conveys the discharged matter with the conveyance water.
Thereby, according to this embodiment, since the 1st pump 21A-the 3rd pump 21C are not operated simultaneously, an electric power peak can be suppressed. Furthermore, since the conveyance water in the 1st storage tank 16 is not supplied in large quantities simultaneously, the capacity | capacitance of the 1st storage tank 16 can be made small. As a result, it is easier to secure the installation space for the first storage tank 16.

Moreover, according to the toilet system 10 of this embodiment, by supplying the 1st storage tank 16 with the 2nd storage tank 17 which stores rainwater and miscellaneous drainage as conveyance water, and the conveyance water in the 2nd storage tank 17 are supplied. The replacement part 30 for replacing the transport water in the first storage tank 16 is further provided.
Thereby, according to this embodiment, the quality of the conveyance water in the 1st storage tank 16 can be improved.
