[First Embodiment]
As shown in FIG. 1, the toilet system 1 of the first embodiment includes a plurality of toilets 2, a plurality of toilet discharge pipes 3, a horizontal pipe 4 as a distribution pipe, a water tank 6, an overflow pipe 5, and a circulation A circulation pipe 7 as a line, a negative pressure pipe 74 (negative pressure means), a water tank drain pipe 9 as a drainage section, a horizontal pipe inspection pipe 41, an overflow pipe inspection pipe 53, and a downstream side circulation path inspection pipe 73 A circulation pump 11, a negative pressure fan 12 (negative pressure means), a water level detection sensor 13 as a water level detection unit, and a control unit 10. In FIG. 1, the path of electrical connection is indicated by a broken line.

The plurality of toilets 2 are installed side by side in a predetermined direction on the floor surface 101 on a predetermined floor of a building or an apartment, for example. The floor surface 101 is an installation surface on which a plurality of toilets 2 are installed. Toilet drain pipes 3 are connected to the lower portions of the plurality of toilets 2, respectively. The toilet bowl 2 includes a toilet bowl 21, and a toilet seat 22 and a toilet lid 23 that are attached to the upper part of the toilet bowl 21 so as to be openable and closable with respect to the toilet bowl 21.

An overflow surface 21 a is formed on the upper edge of the toilet bowl 21. In the present embodiment, the overflow surface 21 a refers to a horizontal plane including the upper edge of the toilet bowl 21 from which water overflows when water is continuously introduced into the toilet bowl 21.

A lower opening 21 b is formed in the lower part of the toilet bowl 21. From the lower opening 21b of the toilet bowl 21, filth such as excrement (exhaust) is discharged.
The toilet bowl 2 may be an anhydrous toilet bowl that does not wash the toilet bowl with water, or may be a flush toilet bowl that cleans the toilet bowl with water. In the case of the toilet bowl of the washing method, the washing water used for washing the waste such as excrement is discharged from the lower opening 21b of the toilet bowl 21 in addition to the waste such as excrement.

The toilet bowl 2 has a flapper mechanism that opens and closes the lower opening 21b. The flapper mechanism includes a flapper valve 24 and a flapper valve rotation shaft (not shown). The flapper valve 24 is configured to be able to open and close the lower opening 21b of the toilet bowl 21. The flapper valve 24 has a balance arm portion (not shown) to which a weight is attached.

When the weight of the dirt accumulated on the upper surface of the flapper valve 24 becomes larger than the weight of the weight in the balance arm portion, the flapper valve 24 pivots downward around the flapper valve pivoting shaft, and the lower opening 21b Opened. Thereby, the filth accumulated on the upper surface of the flapper valve 24 is discharged through the lower opening 21b. After the filth is discharged, the flapper valve 24 returns to the position where the lower opening 21b is closed.
Since the flapper mechanism has a mechanical structure, a predetermined time is required until the flapper valve 24 closes the lower opening 21b after the flapper valve 24 opens the lower opening 21b.

The plurality of toilet bowl discharge pipes 3 lead out filth such as excrement discharged from the plurality of toilet bowls 2 to the horizontal pipe 4. Each of the plurality of toilet drain pipes 3 extends downward from the lower part of the plurality of toilets 2.
The upper end portion of the toilet discharge pipe 33 is connected to the lower end portion of the toilet bowl 21 through the connection socket 25. The connection socket 25 is attached to the floor surface 101 and is formed in a tubular shape extending upward from the floor surface 101. A packing (not shown) is sandwiched between the lower end portion of the toilet bowl 21 and the connection socket 25.
The lower ends of the plurality of toilet discharge pipes 3 are connected to the horizontal pipe 4.

The horizontal tube 4 is disposed below the plurality of toilets 2 so as to extend in the horizontal direction. The horizontal tube 4 extends linearly along the direction in which the plurality of toilets 2 are arranged below the floor surface 101. The horizontal tube 4 is formed in a straight line that is slightly inclined downward so that the water tank 6 side is on the bottom. The lower ends of the plurality of toilet discharge pipes 3 are connected to the upper portion of the horizontal tube 4 at the positions where the plurality of toilets 2 are arranged.

The horizontal tube 4 extends from the most upstream part 4 a to the water tank 6. The most upstream part 4a is the most upstream end of the horizontal pipe 4, and is located upstream of the upstream part 4b of the horizontal pipe 4 to which an overflow pipe 5 (described later) is connected. The upstream portion 4b in the horizontal tube 4 is a portion upstream of the most upstream toilet 2 among the plurality of toilets 2, and an overflow tube 5 (described later) is connected thereto.
Conveyed water circulated by a circulation pipe 7 to be described later is supplied to the most upstream part 4a in the horizontal pipe 4.

In the present embodiment, when filth and transport water flow through the horizontal tube 4, the filth and transport water have a space above the inside of the horizontal tube 4 and are accumulated on the lower side. The horizontal tube 4 is distributed. Therefore, inside the horizontal tube 4, there are a liquid phase portion in which the filth and the transport water circulate and a gas phase portion in which gas exists.

The downstream end of the horizontal tube 4 is connected to the gas phase portion of the water tank 6. The gas phase portion of the horizontal tube 4 and the gas phase portion of the water tank 6 (described later) communicate with each other.

A horizontal pipe inspection pipe 41 is connected to the most upstream part 4a of the horizontal pipe 4. The horizontal pipe inspection pipe 41 extends laterally from the upstream end of the horizontal pipe 4. A horizontal pipe inspection port 411 is formed at the end of the horizontal pipe inspection pipe 41 opposite to the horizontal pipe 4.

The horizontal pipe inspection port 411 is open to the side below the floor surface 101. The horizontal pipe inspection port 411 is used when the horizontal pipe 4 is inspected and cleaned. The horizontal tube inspection port 411 is closed by a horizontal tube inspection port cover member 412.

The water tank 6 is connected to the downstream end of the horizontal pipe 4. The water tank 6 is a tank that stores filth and transport water flowing through the horizontal pipe 4. The water tank 6 is disposed below the floor surface 101. In the water tank 6, filth and transport water are stored with a space above. Therefore, in the water tank 6, there are a liquid phase portion in which the filth and the transport water are stored, and a gas phase portion in which gas exists.

The circulation pipe 7 circulates the conveyance water stored in the water tank 6 to the most upstream part 4a in the horizontal pipe 4. The circulation pipe 7 has an upstream side circulation path 71 and a downstream side circulation path 72.

The upstream end of the upstream circulation path 71 is connected to a circulation pump 11 disposed in the liquid phase portion of the water tank 6. The downstream end of the upstream circulation path 71 is connected to the upper end 72 a of the downstream circulation path 72.

The downstream circulation path 72 is connected to the uppermost stream portion 4a of the horizontal pipe 4 in a standing state. The lower end of the downstream circulation path 72 is connected to the most upstream part 4 a of the horizontal pipe 4. The downstream end of the upstream circulation path 71 is connected to the side of the upper end 72 a of the downstream circulation path 72. Thereby, the downstream-side circulation path 72 supplies the transport water circulated by the upstream-side circulation path 71 to the uppermost stream portion 4 a of the horizontal pipe 4.

A downstream circuit inspection pipe 73 is connected to the upper end 72 a of the downstream circuit 72. The downstream-side circulation path inspection pipe 73 extends upward from the upper end portion 72 a of the downstream-side circulation path 72. A downstream circulation path inspection port 731 is formed at the end of the downstream circulation path inspection pipe 73 opposite to the downstream circulation path 72.

The downstream-side circulation path inspection port 731 opens upward above the floor surface 101. The downstream circulation path inspection port 731 is used when the downstream circulation path 72 is inspected or cleaned. The downstream-side circulation path inspection port 731 is closed by the downstream-side circulation path inspection port cover member 732.

The circulation pump 11 is arranged in the liquid phase part of the water tank 6. The circulation pump 11 sends the conveyance water stored in the water tank 6 to the circulation pipe 7. The circulation pump 11 supplies the conveyance water stored in the water tank 6 to the most upstream part 4 a of the horizontal pipe 4 through the circulation pipe 7. The circulation pump 11 constitutes supply means for supplying the transport water to the uppermost stream portion 4 a of the horizontal pipe 4.

The overflow pipe 5 rises from the horizontal pipe 4, bends to the water tank 6 side at a predetermined height, extends in the horizontal direction on the water tank 6 side, and is connected to the water tank 6. The overflow pipe 5 is disposed at a position below the overflow surface 21 a of the plurality of toilets 2. In this embodiment, when clogging occurs in the horizontal tube 4 at a position between the horizontal tube 4 and the floor surface 101, the overflowed water from the horizontal tube 4 is escaped.

The overflow pipe 5 has a vertical overflow pipe 51 and a horizontal overflow pipe 52.

The vertical overflow pipe 51 rises from the horizontal pipe 4 and is formed. The upstream end (lower end) of the vertical overflow pipe 51 is connected to the upstream portion 4 b of the horizontal pipe 4. The upstream portion 4 b in the horizontal tube 4 is a portion upstream of the most upstream toilet 2 a among the plurality of toilets 2 in the horizontal tube 4, and a portion downstream of the most upstream portion 4 a in the horizontal tube 4. It is. An end (upper end) 51 a on the downstream side of the vertical overflow pipe 51 is located at a height between the horizontal pipe 4 and the floor surface 101. An upper end (downstream end) 51 a of the vertical overflow pipe 51 branches into a horizontal overflow pipe 52 and an overflow pipe inspection pipe 53.

The horizontal overflow pipe 52 is a portion that extends in parallel with the horizontal pipe 4 in the overflow pipe 5. The horizontal overflow pipe 52 extends linearly from the upper end portion 51 a of the vertical overflow pipe 51 in the horizontal direction on the water tank 6 side between the horizontal pipe 4 and the floor surface 101. The lateral overflow pipe 52 is formed in a linear shape that is slightly inclined so that the water tank 6 side is on the bottom. The lateral overflow pipe 52 may be a portion that extends along with the horizontal pipe 4 and may not be parallel to the horizontal pipe 4.
The upstream end of the horizontal overflow pipe 52 is connected to the upper end 51 a of the vertical overflow pipe 51. The downstream end of the horizontal overflow pipe 52 is directly or indirectly connected to the gas phase portion in the water tank 6.

The horizontal overflow pipe 52 described above, when clogged in the horizontal pipe 4, causes the water overflowing from the horizontal pipe 4 and flowing into the vertical overflow pipe 51 to be lower than the overflow surface 21 a of the toilet 2 in the height direction. At the position (the upper end portion 51a of the vertical overflow pipe 51), the horizontal overflow pipe 52 allows it to escape in the horizontal direction. Then, the lateral overflow pipe 52 circulates the water escaped in the lateral direction toward the water tank 6.

The overflow pipe 5 configured as described above has an upstream end (upstream end (lower end) of the vertical overflow pipe 51) connected to the gas phase portion of the horizontal pipe 4, and a downstream end. The downstream end of the horizontal overflow pipe 52 is connected to the gas phase portion of the water tank 6. Therefore, the overflow pipe 5 allows the horizontal pipe 4 and the water tank 6 to communicate with each other, and in a state where water does not flow into the overflow pipe 5, the overflow pipe 5 is located between the gas phase part of the horizontal pipe 4 and the gas phase part of the water tank 6. It functions as a vent pipe for venting gas.

An overflow pipe inspection pipe 53 is connected to the upper end part (downstream end part) of the vertical overflow pipe 51. The overflow pipe inspection pipe 53 extends upward from the upper end portion (downstream end portion) 51 a of the vertical overflow pipe 51. An overflow pipe inspection port 531 is formed in the overflow pipe inspection pipe 53. The overflow pipe inspection port 531 is open upward and below the floor surface 101. The overflow pipe inspection port 531 is used when the overflow pipe 5 and the horizontal pipe 4 are inspected and cleaned. The overflow pipe inspection port 531 is closed by the overflow pipe inspection port cover member 532.

The water level detection sensor 13 is a sensor that detects the water level of the overflow pipe 5. The water level detection sensor 13 is attached at a predetermined height from the top of the horizontal tube 4 inside the vertical overflow tube 51. The water level detection sensor 13 is electrically connected to the control unit 10. The water level detected by the water level detection sensor 13 is transmitted to the control unit 10 as a detection signal.

The negative pressure pipe 74 extends upward from the upper part of the water tank 6. The upstream end portion of the negative pressure pipe 74 is connected to the gas phase portion of the water tank 6. The downstream end of the negative pressure pipe 74 is open to the outside of the water tank 6.

The negative pressure fan 12 is arranged in the middle of the negative pressure pipe 74. The negative pressure fan 12 sucks air (gas) in the gas phase portion of the water tank 6 so that the inside of the gas phase portion of the horizontal tube 4 has a negative pressure.

The water tank drain pipe 9 discharges the transport water stored in the water tank 6 to the outside of the water tank 6 as waste water. The upstream end of the water tank drain pipe 9 is connected to the liquid phase part of the water tank 6. The downstream side of the water tank drain pipe 9 is connected to a discharge destination such as a sewer pipe.

A drain trap 91 is disposed in the middle of the water tank drain pipe 9. The drain trap 91 is formed by a U-shaped U-shaped tube that protrudes downward, and forms a sealed portion 911 (blocking portion) that blocks air flow. The sealed water portion 911 is configured by a portion where water is accumulated in the U-shaped tube of the drain trap 91. The drain trap 91 accumulates drainage in the sealed water portion 911, thereby blocking the drainage flow path of the water tank drain pipe 9 with the sealed water and preventing odors and pests from entering the water tank 6 from the discharge destination. Further, the entire space of the water tank 6, the horizontal pipe 4 and the overflow pipe 5 can be efficiently maintained at a negative pressure by using the negative pressure fan 12.

The control unit 10 is electrically connected to the circulation pump 11, the negative pressure fan 12, the water level detection sensor 13, and the like. The control unit 10 executes various controls of the toilet system 1. For example, the control unit 10 performs the following control.

The control unit 10 controls the negative pressure fan 12 so as to suck air (gas) in the gas phase portion of the water tank 6 so that the gas phase portion of the horizontal tube 4 becomes negative pressure.
The control unit 10 controls the driving of the circulation pump 11 so as to send the conveyance water stored in the water tank 6 to the circulation pipe 7. For example, the control unit 10 controls the driving of the circulation pump 11 so that the driving is performed for a predetermined time every predetermined time (for example, every 15 minutes, every 30 minutes, and every hour).
When the water level detection sensor 13 detects that the level of the transport water overflowing from the horizontal pipe 4 and flowing into the overflow pipe 5 exceeds the predetermined water level, the control unit 10 stops driving the circulation pump, or Control is performed so as to notify the abnormality. For example, the control unit 10 detects an abnormality that the horizontal tube 4 is clogged by a notification unit (not shown) such as a display unit (display, etc.), a sound unit (buzzer, speaker, etc.), a light emitting unit (lamp, etc.). , Notify outside.

Next, operation | movement of the toilet system 1 of this embodiment is demonstrated.
First, in the use state of the toilet system 1 of this embodiment, control by the control part 10 is performed so that the gas phase part of the horizontal pipe 4 arrange | positioned under the some toilet bowl 2 may become a negative pressure.
Specifically, the control unit 10 controls the negative pressure fan 12 so as to suck air (gas) in the gas phase portion of the water tank 6. As a result, the gas phase portion of the water tank 6 becomes negative pressure, and the gas phase portion of the horizontal tube 4 communicating with the gas phase portion of the water tank 6 also becomes negative pressure. Further, since the gas phase portion of the water tank 6 becomes negative pressure, the inside of the overflow pipe 5 becomes negative pressure, and the gas phase portion of the horizontal pipe 4 also becomes negative pressure. Therefore, since the gas phase portion of the horizontal tube 4 becomes negative pressure, even if the flapper valve 24 is open, the odor of the filth and the transport water flowing through the horizontal tube 4 flows back to the toilet 2. Can be reduced.

In particular, the flapper valve mechanism of the toilet 2 in this embodiment has a mechanical structure, and it takes time until the flapper valve 24 is closed after being opened. Therefore, even if it takes time until the flapper valve 24 is opened and closed, it is effective that the filth flowing through the horizontal pipe 4 and the odor from the transport water enter the toilet room from the inside of the toilet bowl 2. Can be suppressed.

Also, a drain trap 91 is provided in the water tank drain pipe 9. Therefore, when the gas-phase part of the water tank 6 is made negative by the negative pressure fan 12 by the sealing part 911 of the drain trap 91, the intrusion of air from the water tank drain pipe 9 is suppressed, and the water tank is efficiently The gas phase portion of 6 can be set to a negative pressure.

Next, the transport water stored in the water tank 6 is supplied to the uppermost stream portion 4a of the horizontal tube 4 in a state where the gas phase portion of the horizontal tube 4 is set to a negative pressure. Specifically, the control unit 10 controls the driving of the circulation pump 11 so as to send the conveyance water stored in the water tank 6 to the circulation pipe 7. For example, the control unit 10 controls the driving of the circulation pump 11 so that the driving is performed for a predetermined time every predetermined time (for example, every 15 minutes, every 30 minutes, and every hour). In this way, the circulation pump 11 circulates the transport water stored in the water tank 6 through the horizontal pipe 4.

Thereby, when there is no clogging of filth etc. in the horizontal pipe 4, filth is conveyed from the toilet bowl 2 to the horizontal pipe 4 toward the water tank 6 by the conveyance water supplied to the most upstream part 4a of the horizontal pipe 4. The water tank 6 is stored. The conveyance water stored in the water tank 6 is sent to the circulation pipe 7 by driving the circulation pump 11. The transport water sent from the water tank 6 to the circulation pipe 7 is supplied to the most upstream part 4 a of the horizontal pipe 4. Then, again, the filth discharged from the toilet bowl 2 to the horizontal pipe 4 is conveyed toward the water tank 6 by the conveyance water supplied to the uppermost stream portion 4 a of the horizontal pipe 4. In this way, the operation of circulating the transport water in the horizontal tube 4 is repeated. In addition, the waste water increased due to the input of filth and washing water from the toilet bowl 2 is drained through a water tank drain pipe 9 into a sewer pipe or the like.

Here, the transport water stored in the water tank 6 is supplied to the most upstream part 4a of the horizontal pipe 4. Therefore, the conveyance water circulated by the circulation pipe 7 is less likely to accumulate on the upstream side of the horizontal pipe 4. Further, a downstream circulation path inspection port 731 is formed at the upper end portion of the downstream circulation path inspection pipe 73 extending upward from the downstream circulation path 72. Therefore, the downstream circulation path 72 can be cleaned by the downstream circulation path inspection port 731.

Further, when the horizontal pipe 4 is not clogged, the overflow pipe 5 functions as a vent pipe for allowing gas to flow between the gas phase portion of the horizontal tube 4 and the gas phase portion of the water tank 6.

On the other hand, when clogging such as filth occurs in the horizontal pipe 4, the filth and the transport water discharged from the toilet bowl 2 to the horizontal pipe 4 overflow from the horizontal pipe 4 and flow into the overflow pipe 5. Here, the overflow pipe 5 is configured to allow the water overflowing from the horizontal pipe 4 to escape in the horizontal direction at a height position between the horizontal pipe 4 and the floor surface 101. When the horizontal pipe 4 is clogged with filth or the like, the filth and overflowing water from the horizontal pipe 4 flows into the vertical overflow pipe 51 in the overflow pipe 5 between the horizontal pipe 4 and the floor surface 101. At a height of 5 mm, it is conveyed in the horizontal direction by the horizontal overflow pipe 52 in the overflow pipe 5 and stored in the water tank 6.
Thereby, it is suppressed that a filth and conveyance water overflow from the overflow surface 21a of the toilet bowl 2. In addition, the filth and the overflowing water overflowing from the horizontal pipe 4 can be stored in the water tank 6 through the overflow pipe 5.

In particular, in the present embodiment, the horizontal overflow pipe 52 extends in the horizontal direction at a position lower than the floor surface 101 and higher than the horizontal pipe 4. Therefore, it is suppressed that filth and conveyance water overflow in a position higher than floor surface 101 in toilet bowl 2. For example, the overflow water from the horizontal tube 4 is suppressed from reaching the height of the connection portion between the lower end portion of the toilet bowl 21 and the connection socket 25 as in the present embodiment. Thereby, even if the packing (not shown) arranged in the connection portion between the lower end portion of the toilet bowl 21 and the connection socket 25 is damaged due to deterioration or the like, the filth is removed from the connection portion between the toilet bowl 2 and the connection socket 25. In addition, leakage of the conveyance water is suppressed.

Further, the overflow pipe 5 is connected to the upstream portion 4b upstream of the toilet bowl 2a on the most upstream side of the plurality of toilet bowls 2 in the horizontal pipe 4. Therefore, even if clogging occurs in any place of the horizontal pipe 4, the filth and the transport water flowing through the horizontal pipe 4 flow into the overflow pipe 5. Therefore, even if the horizontal tube 4 is clogged, it is possible to prevent filth and transport water from overflowing from any overflow surface 21a of the plurality of toilets 2.

In addition, when the horizontal pipe 4 is clogged, if the filth and transport water overflow from the horizontal pipe 4 and flow into the vertical overflow pipe 51, the control unit 10 causes the water level detection sensor 13 to detect the filth and transport water. When it is detected that the predetermined water level has been exceeded, the circulation pump 11 is controlled to be stopped. Thereby, when the horizontal pipe 4 is clogged, the circulation pump 11 can be stopped, and it can suppress that filth and conveyance water flow in into the toilet bowl 2 side. Further, when the control unit 10 detects that the water level detection sensor 13 has exceeded the predetermined water level, the control unit 10 controls the notification unit (not shown) to notify the abnormality that the horizontal tube 4 is clogged. Thereby, the clogging of the horizontal tube 4 can be notified at an early stage, and the horizontal tube 4 can be quickly maintained and repaired.

The toilet system 1 according to the first embodiment described above has the following effects.

The toilet system 1 according to the present embodiment includes a plurality of toilets 2, a horizontal pipe 4 through which filth and transported water discharged from the plurality of toilets 2 circulate, and an upstream side of the plurality of toilets 2 in the horizontal pipe 4. An overflow pipe 5 having a horizontal overflow pipe 52 connected to the upstream portion 4b upstream of the side toilet 2a and extending in parallel with the horizontal pipe 4, and an upstream portion 4b of the horizontal pipe 4 to which the overflow pipe 5 is connected The overflow system 5 includes a circulation pump 11 that supplies water to the upstream side, and the overflow pipe 5 is disposed at a position below the overflow surface 21a of the plurality of toilet bowls 2.

Therefore, even when the horizontal pipe 4 is clogged, the filth and the overflow water flowing from the horizontal pipe 4 flow into the overflow pipe 5. Thereby, it can suppress that a filth and conveyance water overflow from the overflow surface 21a of the toilet bowl 2. FIG.

Further, the toilet system 1 of the present embodiment is connected to the downstream side of the horizontal pipe 4 and has a water tank 6 for storing filth and conveyance water flowing through the horizontal pipe 4, and the conveyance water stored in the water tank 6 for the horizontal pipe 4. The circulation pipe 7 that circulates to the most upstream part 4a and the circulation pump 11 that feeds the conveyance water stored in the water tank 6 to the circulation pipe 7 are further provided, and the supply means is the circulation pump 11. Therefore, the conveyance water which circulates conveyance water by the circulation piping 7 and conveys filth can be reused. Therefore, it is not necessary to use clean water for conveyance of filth, and the amount of clean water used can be reduced.

In the toilet system 1 of the present embodiment, the downstream end of the overflow pipe 5 is connected directly or indirectly to the gas phase portion in the water tank 6. Therefore, the water overflowing from the horizontal tube 4 can be stored in the water tank 6 through the overflow tube 5. Further, when the horizontal pipe 4 is not clogged, the overflow pipe 5 can function as a vent pipe for allowing gas to flow between the gas phase portion of the horizontal tube 4 and the gas phase portion of the water tank 6.

Further, when the water level detection sensor 13 for detecting the water level of the overflow pipe 5 and the water level detected by the water level detection sensor 13 exceeds a predetermined water level, the driving of the circulation pump 11 is stopped or an abnormality is caused to the outside. And a control unit 10 that performs control so as to notify the user. Therefore, when the horizontal pipe 4 is clogged and filth and transport water flow into the overflow pipe 5, the circulation of the transport water by the circulation pump 11 can be stopped.
