Description

  The present invention relates to a drainage connector.

  The toilet body of the Western-style flush toilet disclosed in Patent Document 1 has a reservoir part in the toilet drainage channel that is connected to the downstream side of the toilet bowl. The Western style flush toilet includes an intake device that sucks air from the toilet drainage channel.

  In this Western style flush toilet, when toilet flushing is started and cleaning water is supplied to the reservoir, the reservoir is sealed with the cleaning water. Thereby, a closed space is formed in the toilet drainage channel on the upstream side of the water reservoir. When the air in the closed space is sucked by the intake device, the toilet drainage channel can be quickly filled with the wash water due to a synergistic effect with the wash water supplied to the toilet bowl. For this reason, since a siphon effect | action can be produced early and reliably, the waste in a water seal part can be reliably discharged | emitted from the toilet bowl by a siphon effect | action.

  However, in the conventional Western-style flush toilet, the outer peripheral surface of the toilet drainage channel in which the water storage portion is formed is exposed, so that condensation tends to occur on the outer peripheral surface. For this reason, the dew condensation produced on the outer peripheral surface of the toilet drainage channel may flow down to the floor surface and stains on the floor surface may occur. In addition, the sound generated when the cleaning water flows into the water reservoir is likely to leak to the outside, and there is a risk of lack of silence.

  This invention is made | formed in view of the said conventional situation, Comprising: It is set as the problem which should be solved to provide the drainage connector which can implement | achieve the flush toilet bowl excellent in usability.

The drainage connector of the present invention is a drainage that communicates a drainage port of a toilet drainage channel connected to a downstream side of a toilet bowl formed in a toilet body and a connection port of a drainage pipe taken out into a room where the toilet body is installed. In the connection tool,
A housing provided with an inflow port connected to the drainage port, an outflow port connected to the connection port, and an internal pipe disposed in the housing;
The internal pipe has an upstream port that communicates with the inflow port, and has an upstream pipe that forms a descending flow path at the time of installation, and a downstream port that is connected to the upstream pipe and opens along the inner surface of the housing. And is composed of downstream piping that forms an ascending flow path when installed ,
Washing water flowing out from the downstream port into the casing is drained from the outlet into the drain pipe while swirling along the inner surface of the casing .

  In this drainage connector, a water reservoir is formed in the internal pipe at the time of installation. Since the internal pipe is disposed in the housing, the outer peripheral surface of the internal pipe in which the water reservoir is formed is not exposed to the outside air, and condensation is unlikely to occur. Even if condensation occurs on the outer peripheral surface of the internal pipe, the condensation falls into the housing and is drained from the outlet of the housing to the drain pipe. For this reason, generation | occurrence | production of the stain | pollution | contamination stain | pollution | contamination of the floor surface by dew condensation can be prevented. Moreover, since the sound generated by the washing water flowing into the water reservoir is difficult to leak to the outside due to the casing that covers the internal piping, the noise can be reduced.

  Therefore, the drainage connector of the present invention can realize a flush toilet bowl with excellent usability.

  The upper end of the lowest descending part of the descending channel and the lower end of the most ascending part of the ascending channel may be located at the same horizontal position or the latter above the former when installed. In this case, the water storage part formed in the internal pipe is completely sealed with the washing water. For this reason, a closed space is formed in the internal piping and the toilet drainage channel on the upstream side of the water reservoir. Thereby, when toilet bowl washing | cleaning is performed, the toilet drainage channel and the inside piping can be filled with washing water earlier, and a siphon action can be produced earlier.

  It is preferable to provide an intake device that sucks air in a closed space formed in the internal piping and the toilet drainage channel on the upstream side of the water reservoir. In this case, when toilet flushing is performed, the air in the closed space is sucked by the air intake device, so that the toilet drainage channel and the internal piping can be filled with flush water earlier, and the siphon action can be further accelerated. Can be generated.

  In this drainage connector, even when negative pressure is generated downstream of the drain pipe taken out into the room, the housing forms an internal space that extends from the outlet, so negative pressure to the reservoir is reduced. Can weaken the impact. For this reason, due to the negative pressure in the drainage pipe, the wash water in the reservoir is not easily sucked downstream, and the sealed water in the reservoir is not easily destroyed. Therefore, the closed space formed on the upstream side of the water reservoir is maintained, and the siphon action can be generated early and reliably.

Downstream port, it opens along the inner surface of the housing. In this case, the washing water flowing out from the downstream port can be drained from the outlet along the inner side surface of the housing. For this reason, it is possible to reduce the running noise of the washing water.

  The inner side surface of the housing may have a substantially circular horizontal cross section. In this case, the washing water flowing out from the downstream port is drained from the outlet while swirling along the inner surface of the housing. For this reason, washing water can be drained more smoothly from the housing.

  The inner surface of the housing may have a downwardly inclined surface toward the outlet. In this case, the wash water can be reliably drained from the outlet.

Another drainage connecting device of the present invention communicates a drainage port of a toilet drainage channel connected to a downstream side of a toilet bowl formed in a toilet bowl body and a connection port of a drainage pipe taken out into a room where the toilet bowl body is installed. In drainage fittings to
Provided on the upper surface is an inlet connected to the drain outlet, and provided on the lower surface is an outlet connected to the connection port, and an internal pipe disposed in the casing,
The internal pipe has an upstream port that communicates with the inflow port, and has an upstream pipe that forms a descending flow path at the time of installation, and a downstream port that is connected to the upstream pipe and opens into the housing. It consists of downstream piping that forms the rising channel,
The inflow port and the outflow port are concentric when viewed from above during installation.
In this case, the toilet outlet is provided at the center of the left and right of the toilet body, and the drain pipe is taken out to the center of the left and right of the room where the toilet body is installed, so that the toilet body can be easily installed at the center of the left and right of the room. it can.

  A planar heater can be attached to the outer surface of the housing. In this case, since the inside of a housing | casing can be warmed with a planar heater, freezing of the washing water of the water storage part provided in internal piping can be prevented.

Hereinafter, Examples 1 and 2 and Reference Examples 1 and 2 in which the drainage connector of the present invention is embodied in a Western style flush toilet will be described with reference to the drawings.

<Example 1>
As shown in FIG. 1, the Western style flush toilet of Example 1 includes a toilet main body 1, a toilet cleaning device 100, and an intake device 200. The toilet bowl cleaning apparatus 100 is connected to a water pipe and has a strainer, a constant flow valve, and an on-off valve. The intake device 200 includes a suction tank 201 and a drive device 202 that drives the suction tank 201. Illustration of the toilet seat and toilet lid is omitted.

  The toilet body 1 has a rim 3 on the upper inner periphery of the toilet bowl 2. In addition, the toilet body 1 has a water seal portion 4 in which wash water is stored. The toilet drainage channel 5 connected to the downstream side of the toilet bowl 2 includes an ascending flow path formed by an upstream drainage pipe 5A formed integrally with the toilet body 1 and an upstream drainage pipe 5A that is the highest rising portion of the ascending flow path. It is connected to the downstream end via a packing 5P, and is composed of a descending flow path formed by a downstream drain pipe 5B formed separately from the toilet body 1. A planar heater 50 is attached to the lower surface of the toilet bowl 2 and the upstream drain pipe 5A to prevent freezing of the washing water staying in the toilet bowl 2 and the upstream drain pipe 5A.

  The downstream end of the downstream drain pipe 5 </ b> B forms a drain port 6 of the toilet drainage channel 5. The downstream drain pipe 5B is formed with a communication pipe 7 extending vertically upward on the upper surface portion on the downstream side from the uppermost part of the toilet drainage channel 5. The suction pipe 201A of the suction tank 201 is inserted into the upper opening of the communication pipe 7 via the packing 7P, and is connected in an airtight state. Note that an O-ring may be fitted to the outer surface of the suction pipe 201A, and the suction pipe 201A may be inserted into the communication pipe 7 and connected in an airtight state.

  The drainage port 6 communicates with the connection port 31 of the drainage pipe 30 taken out to the floor F in the room where the toilet body 1 is installed via the drainage connector 10. As shown in FIGS. 1 to 4, the drainage connector 10 includes a housing 11 including an upper housing 11 </ b> A and a lower housing 11 </ b> B, and an internal pipe 20 disposed in the housing 11.

  The upper housing 11A has a cylindrical first connection portion 13 that extends vertically upward from the upper surface. The upper end of the first connection portion 13 forms an inflow port 12. The lower portion of the first connection portion 13 extends downward from the upper surface of the upper housing 11A, and a circular opening 15 having a smaller diameter than the inflow port is formed in the central portion. A columnar hanging wall 16 extending downward is formed at the lower peripheral edge of the opening 15.

  A packing 12 </ b> P is attached to the inflow port 12. The packing 12P is formed of a circular upper surface 12U provided with an opening 12K having a smaller diameter than the downstream drain pipe 5B, and a body 12D extending downward from the periphery of the upper surface 12U. The body 12 </ b> D of the packing 12 </ b> P has a concave portion that is formed on the inner peripheral surface and engages with the flange 14 formed on the outer peripheral surface of the first connection portion 13. When connecting the downstream drainage pipe 5B to the drainage connector 10, the downstream drainage pipe 5B is inserted into the inlet 12 from above so as to widen the opening 12K of the packing 12P attached to the inlet 12 The downstream drain pipe 5B can be easily connected to the drain connector 10.

  The upper housing 11A has a side wall 11C extending downward from the periphery of the upper surface. The inner side surface of the side wall 11C has a substantially circular horizontal cross section. A side wall 11C on the rear side of the toilet body 1 is an inclined surface 11D. Thereby, the housing 11 can be reduced in size, and the drive device 202 of the intake device 200 and the like can be easily stored in the rear storage space S formed by being surrounded by the peripheral wall W of the toilet body 1.

  The lower housing 11B has an outer wall 11E continuous to the side wall 11C of the upper housing 11A, and an inner wall 11F having an inner surface formed flush with the inner surface of the side wall 11C. A columnar second connection portion 17 extending in the vertical direction is provided at the lower end of the inner wall 11F. The lower end of the second connection portion 17 forms an outlet 18. The second connection portion 17 is inserted into the connection port 31 of the drain pipe 30 taken out to the floor surface F and connected to the drain pipe 30. The inner wall 11 </ b> F is formed on a downwardly inclined surface facing the outlet 18. A planar heater 51 is affixed to the outer surface of the inner wall 11F.

  As shown in FIGS. 2 to 4, the lower housing 11 </ b> B has a notch portion 11 </ b> G provided at the left and right lower ends. When fixing the drainage connector 10 to the floor F, there is no water leakage or odor leakage from the connecting portion between the outlet 18 of the drainage connector 10 and the connection port 31 of the drainage pipe 30 through the notch 11G. Can be confirmed.

  Further, the lower housing 11B has a mounting piece 19 provided in front of the lower end and extending in the left-right direction. Through holes 19H through which wood screws N for fixing the casing 11 to the floor surface F can be inserted are provided at both left and right ends of the mounting piece 19. Further, a slit 19S communicating with the inside of the outer wall 11E of the lower housing 11B is provided on the lower surface of the mounting piece 19. Thereby, when removing the drainage connector 10 attached to the floor surface F, the drainage connector 10 is disconnected from the drainage pipe 30 by inserting a saw blade from the slit 19S and cutting the second connection part 17. be able to.

  As shown in FIGS. 1 to 3, the internal pipe 20 disposed in the housing 11 has an inlet 21 at the upper end, and is connected to an upstream pipe 22 that forms a downward flow path, and an upstream pipe 22. The downstream pipe 24 is formed and has a downstream port 24 that opens into the housing 11 and forms an ascending flow path. The upper end of the upstream pipe 22 is connected to the hanging wall 16 provided in the upper housing 11A. The upstream pipe 22 is bent below the connecting portion with the hanging wall 16, bent toward the rear side of the toilet body 1, extends obliquely downward, and gradually curves in the lateral direction to form a lowermost portion. The downstream pipe 23 extends obliquely upward while gradually curving from the lowest part to the front side of the toilet body 1. The downstream pipe 23 is connected to the tip portion, and has a tip portion 23 </ b> A that the downstream port 24 is along the inner surface of the housing 11 and opens slightly obliquely downward. The highest rising portion of the rising flow path is formed upstream of the downstream port 24.

  As shown in FIG. 1, the lower end 23U of the most rising part of the ascending channel is located above the upper end 22D of the most descending part of the descending channel. For this reason, the water reservoir R formed in the internal pipe 20 is sealed with the washing water. For this reason, a closed space is formed in the toilet drainage channel 5 on the downstream side of the water seal part 4 and in the internal pipe on the upstream side of the water reservoir R.

  As shown in FIG.1 and FIG.2, since the internal piping 20 which forms the water storage part R is arrange | positioned in the housing | casing 11, the outer peripheral surface of the internal piping 20 in which the water storage part R was formed is outside air. Not exposed to condensation. Even if condensation occurs on the outer peripheral surface of the internal pipe 20, the condensation falls into the housing 11 and is drained from the outlet 18 of the housing 11 into the drain pipe 30. For this reason, the stain | pollution | contamination stain | pollution | contamination of the floor surface F by dew condensation can be prevented. Moreover, since the sound generated by the washing water flowing into the water reservoir R is unlikely to leak to the outside by the casing 11 that covers the internal pipe 20, it is possible to reduce the noise.

  Therefore, the drainage connector 10 of the first embodiment can realize a flush toilet bowl with excellent usability.

  Further, the inflow port 12 provided in the upper housing 11A and the outflow port 18 provided in the lower housing 11B are concentric when viewed from above in a state of being installed on the floor surface F. For this reason, the drain outlet 6 of the toilet drainage channel 5 is provided at the left and right center of the toilet body 1, and the drain pipe 30 is taken out from the left and right center of the room where the toilet body 1 is installed, so that the toilet body 1 is placed at the left and right center of the room. Can be easily installed.

  Moreover, since the inside of the housing | casing 11 can be warmed by the planar heater 51 stuck to the outer surface of the inner wall 11F of the lower housing | casing 11B, the freezing of the washing water of the water reservoir R can be prevented.

  Furthermore, even when negative pressure is generated on the downstream side of the drainage pipe 30, the housing 11 forms an internal space that extends from the outlet, so that the influence of negative pressure on the water reservoir R can be reduced. . For this reason, due to the negative pressure in the drainage pipe 30, the wash water of the water reservoir R is hardly sucked downstream, and the sealed water of the water reservoir R is not easily destroyed. Therefore, the closed space formed on the upstream side of the reservoir portion R is maintained, and the siphon action can be generated early and reliably.

  In the toilet flushing of the Western style flush toilet constructed as described above, flush water is supplied to the rim 3 by the toilet flushing device 100. Then, the water level of the wash water in the toilet bowl 2 rises. When a predetermined amount of cleaning water is supplied and the level of the cleaning water in the toilet bowl 2 reaches a predetermined position, the driving device 202 of the intake device 200 drives the suction tank 201. When air is sucked by the suction tank 201 from the toilet drainage channel 5 in which the closed space on the downstream side of the water seal portion 4 and the upstream side of the reservoir portion R is formed, the closed space is filled with washing water, and the siphon The action occurs early and reliably.

  After the siphon action occurs, the toilet water is supplied to the rim 3 by the toilet bowl cleaning device 100 for a predetermined time. While the washing water is supplied at a predetermined flow rate, the siphon action continues and the filth in the toilet bowl 2 is discharged. Thereafter, the driving device 202 of the intake device 200 drives the suction tank 201 and discharges air from the suction tank 201 to the toilet drainage channel 5. This ends the siphon action. After the siphon action is finished, the cleaning water is supplied to the water sealing part 4 of the toilet body 1 to complete the sealing.

  During this toilet cleaning, the wash water flowing into the housing 11 from the downstream port 24 of the internal pipe 20 is drained from the outlet 18 into the drain pipe 30 while swirling along the inner surface of the housing 11. For this reason, since wash water can be smoothly drained from the housing | casing 11, while a siphon effect | action can be continued, the flowing water sound of wash water can be made small. Further, since the inner wall 11F of the lower housing 11B is formed on a downwardly inclined surface toward the outlet 18, the washing water can be reliably drained from the outlet 18.

<Example 2>
The Western style flush toilet of Example 2 is obtained by changing the shape of the casing of the drainage connector. As shown in FIGS. 5 and 6, the casing 61 of the drainage connector 60 includes an upper casing 61A and a lower casing 61B. About the same structure as Example 1, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  The upper housing 61A has a circular upper surface, and has a cylindrical side wall 63 extending downward from the periphery of the upper surface. The inner side surface of the side wall 63 has a circular horizontal cross section. The lower housing 61B has a side wall 64 that is continuous with the side wall 63 of the upper housing 61A. The lower housing 61B has a pair of attachment pieces 62 provided in front of the lower end of the side wall 64 and extending in the left-right direction. Each attachment piece 62 is provided with a through hole 62H through which a wood screw N for fixing the casing 61 to the floor surface F can be inserted.

  As shown in FIG. 6, a downwardly inclined surface 65 is formed on the inner side surface of the side wall 64 of the lower housing 61 </ b> B from the intermediate portion in the vertical direction toward the outlet 18. A second connection portion 17 is formed continuously from the lower end of the inclined surface 65.

  Since the internal pipe 20 that forms the water reservoir R is disposed in the housing 61, the outer peripheral surface of the internal pipe 20 on which the water reservoir R is formed is not exposed to the outside air, and condensation is unlikely to occur. Even if dew condensation occurs on the outer peripheral surface of the internal pipe 20, the dew condensation falls into the housing 61 and is drained from the outlet 18 of the housing 61 into the drain pipe 30. For this reason, the stain | pollution | contamination stain | pollution | contamination of the floor surface F by dew condensation can be prevented. Moreover, since the sound generated by the washing water flowing into the water reservoir R is unlikely to leak to the outside by the casing 61 that covers the internal pipe 20, it is possible to reduce the noise.

  Therefore, the drainage connector 60 of Example 2 can also realize a flush toilet bowl that is excellent in usability.

  In addition, since the inner side surface of the casing 61 has a circular horizontal cross section, the cleaning water flowing into the casing 61 from the downstream port 24 of the internal pipe 20 is washed to the inner side surface of the casing 61 when cleaning the toilet bowl. Then, the water is drained from the outlet 18 into the drain pipe 30 while swirling. For this reason, the wash water can be smoothly drained from the housing 61, and the running sound of the wash water can be reduced. Moreover, since the downward inclined surface 65 toward the outflow port 18 is formed in the lower housing 61B, the washing water can be surely drained from the outflow port 18.

<Reference Example 1>
The Western-style flush toilet of Reference Example 1 is obtained by changing the shape of the casing of the drainage connector. As shown in FIGS. 7 and 8, the casing 71 of the drainage connector 70 includes an upper casing 71A and a lower casing 71B. About the same structure as Example 1 or Example 2, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  The upper casing 71A has the same configuration as the upper casing 61A of the second embodiment. The lower housing 71B is connected to the side wall 72 and has a horizontal pipe 73 extending in the horizontal direction. The horizontal pipe 73 has a connecting member 74 formed with an outlet 75 connected to the tip and opening downward. The outlet 75 is connected to the drain pipe 30 via a joint member 76 inserted into the connection port 31 of the drain pipe 30.

  Since the internal pipe 20 that forms the water reservoir R is disposed in the casing 71, the outer peripheral surface of the internal pipe 20 on which the water reservoir R is formed is not exposed to the outside air, and condensation is unlikely to occur. Even if condensation occurs on the outer peripheral surface of the internal pipe 20, the condensation falls into the casing 71 and is drained from the outlet 75 of the casing 71 into the drain pipe 30. For this reason, the stain | pollution | contamination stain | pollution | contamination of the floor surface F by dew condensation can be prevented. Moreover, since the sound generated by the washing water flowing into the water reservoir R is unlikely to leak to the outside by the casing 71 that covers the internal pipe 20, it is possible to reduce the noise.

Therefore, the drainage connector 70 of Reference Example 1 can also realize a flush toilet bowl with excellent usability.

  Further, when the toilet body is replaced, the position where the drain pipe 30 is taken out into the room differs depending on the specifications of the toilet body before the replacement. In this case, since the outflow port 75 can be connected to the connection port 31 of the drain pipe 30 by cutting the horizontal pipe 73 to an appropriate length, the toilet body can be easily replaced.

<Reference Example 2>
The Western-style flush toilet of Reference Example 2 is obtained by changing the shape of the internal piping of the drainage connector. As shown in FIG. 9, the internal pipe 90 of the drainage connector 80 has a downstream port 94 that opens toward the outlet 18 provided in the lower housing 61B. About the same structure as Example 1 or Example 2, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  The internal pipe 90 has an inlet 91 at the upper end, and is composed of an upstream pipe 92 that forms a descending flow path, and a downstream pipe 93 that is formed continuously with the upstream pipe 92. The downstream pipe 93 forms an ascending channel and a descending channel continuous to the downstream side of the ascending channel. Since the lower end portion of the downstream pipe 93 is inserted and arranged in the second connection portion 17 of the housing 61, the downstream port 94 of the internal pipe 90 opens toward the outlet 18.

  Since the internal pipe 90 that forms the water reservoir R is disposed in the housing 61, the outer peripheral surface of the internal pipe 90 in which the water reservoir R is formed is not exposed to the outside air, and condensation is unlikely to occur. Even if condensation occurs on the outer peripheral surface of the internal pipe 90, the condensation falls into the housing 61 and is drained from the outlet 18 of the housing 61 into the drain pipe 30. For this reason, the stain | pollution | contamination stain | pollution | contamination of the floor surface F by dew condensation can be prevented. Moreover, since the sound generated by the washing water flowing into the water reservoir R is unlikely to leak to the outside by the casing 71 that covers the internal pipe 20, it is possible to reduce the noise.

Therefore, the drainage connector 80 of Reference Example 2 can also realize a flush toilet bowl with excellent usability.

  Moreover, since the wash water flowing out from the downstream port 94 can be drained directly to the outflow port 18, the running sound of the wash water does not occur in the housing 61, and the noise can be further reduced.

In the above, the present invention has been described with reference to the first and second embodiments. However, the present invention is not limited to the above-described embodiments, and it is needless to say that the present invention can be appropriately modified and applied without departing from the spirit of the present invention. Absent.

  For example, the water reservoir R formed in the internal pipe need not be sealed. In this case, a gap through which air flows is formed above the wash water in the reservoir R, and when the toilet is washed, the wash water is supplied to the reservoir R so that the gap is sealed, A closed space may be formed on the upstream side of the water reservoir R.

  Further, it is not necessary to provide an intake device that sucks air from the toilet drainage channel 5.

  The present invention can be used for flush toilets.
