Description

  The present invention relates to a drainage system, and more particularly, to a so-called siphon-type drainage system used for draining water from peripheral devices such as a unit bath (bathroom, bathtub), kitchen unit, washing machine, and washbasin.

  In recent years, so-called siphon drainage systems have been proposed in place of conventional gradient drainage systems.

  As described in Patent Documents 1 and 2, the siphon drainage system is composed of a water-circulating device and a siphon pipe, and uses a siphon force (negative pressure) generated at a hanging portion of the siphon drain pipe. It is a system that improves the efficiency of drainage from water-circulating equipment.

  In the drainage system, the drainage discharged from the peripheral equipment flows into the siphon drainage pipe and fills the horizontal part and the hanging part of the siphon pipe.

  When the drooping part of the siphon drainage pipe is filled with drainage, the drainage in the drooping part falls due to gravity, so that a suction force corresponding to the head difference in the drooping part, that is, siphoning force is generated inside the horizontal part. The drainage in the horizontal portion is sucked toward the hanging portion by the siphon force, and flows down in the siphon drainage pipe as a so-called full flow in which the inside of the siphon drainage pipe is filled with drainage.

  However, in a water supply device that generates a large amount of drainage at a time, such as a unit bath or a kitchen unit, a siphon drainage system with one siphon drainage pipe has insufficient drainage capacity. Therefore, a double piping system having two or more siphon drain pipes has been proposed.

  In the double piping system, since the processing capacity exceeds the amount of drainage from the peripheral equipment, air is sucked into the drainage from the trap from which the drainage from the peripheral equipment is discharged, and noise such as a zooming noise is generated in the trap.

  Therefore, in order to eliminate such a zoom sound, a drainage system in which two siphon drainage pipes are arranged up and down, and the upper siphon drainage pipe is provided with a gradient in which the drainage is discharged has been studied. .

  According to the drainage system, when the drainage approaches the end and the amount of drainage decreases, air is sucked from the upper siphon drainage pipe. Therefore, since no air is sucked through the trap, the noise of the trap is eliminated.

  Examples of such a drainage system are shown in FIGS. The double piping system shown in FIG. 23 includes a joint portion 110 to which a 50A cheese 112 and a 50A elbow 113 are connected. The cheese 112 of the joint 110 is connected to a drain introduction pipe 111 from a water-related device such as a kitchen unit, and is further connected to a first siphon drain pipe 114 communicating with a drain stand (not shown). ing. A second siphon drain pipe 115 is connected to the end of the elbow 113 opposite to the side connected to the cheese 112.

  Here, since the siphon drain pipes 114 and 115 are usually 20A resin pipes, they are much thinner than the 50A cheese 112 and elbow 113. Therefore, a reducer (increase) 116 is inserted between the cheese 112 and the siphon drain pipe 114, and between the elbow 113 and the siphon drain pipe 115, there are two reducers 116 and a pipe 117 positioned therebetween. The joint is inserted.

  The double piping system shown in FIG. 24 is provided with a bottomed cylindrical base 121 to which a drainage introduction pipe 111 from a water-circulating device is connected, and a side surface of the cylindrical base 121, and a siphon drain pipe 124 is connected thereto. A connecting pipe 122 and a connecting pipe 123 to which a siphon drain pipe 125 is connected. The connection pipe 122 and the connection pipe 123 are thin tubes of about 20A having the same inner diameter as the siphon drain pipe 124 and the siphon drain pipe 125, and are arranged in the vertical direction. A large diameter part into which the siphon drain pipe 124 and the siphon drain pipe 125 are inserted is formed at the ends of the connection pipe 122 and the connection pipe 123, and boundaries between the large diameter part and the connection pipe 122 and the connection pipe 123 are respectively formed. A step 122a and a step 123a for abutting the siphon drain pipe 124 and the siphon drain pipe 125 are formed.

  When a large amount of drainage is discharged from the peripheral equipment at a time, as in the case of draining the drainage, in the double piping system shown in FIG. 23, the drainage is first received by the cheese 112 and the elbow 113, and then the siphon drainage. Drain through the pipe 114 and the siphon drain pipe 115. In other words, when the drainage is drained, drainage flows while the siphon drainage pipe 114 and the siphon drainage pipe 115 are full, forming a siphon, thereby ensuring a necessary drainage amount. Similarly, in the double piping system shown in FIG. 24, the cylindrical base 121 first receives drainage, and then drains through the siphon drainage pipe 124 and the siphon drainage pipe 125.

On the other hand, at the time of continuous drainage, immediately after the start of drainage, drainage is performed using not only the lower siphon drainage pipe 115 or 125 but also the upper siphon drainage pipe 114 or 124 as in the case of the drainage drainage. . However, the upper siphon drain pipe 114 or 124 is used only immediately after the start of drainage, and the drainage is immediately discharged only through the lower siphon drain pipe 115 or 125. Accordingly, since air is sucked from the upper siphon drain pipe 114 or 124, air is prevented from being sucked from the trap of the water-circulating device. This prevents abnormal noise from being generated from the trap.

  However, in these drainage systems, it is necessary to add a downward slope to the upper siphon drainage pipe 114 or 124. Then, if it is intended to provide a sufficiently large downward slope to the upper siphon drain pipe 114 or 124, it is necessary to increase the distance S between the upper siphon drain pipe 114 or 124 and the lower siphon drain pipe 115 or 125. There is. Therefore, the drainage system may not fit in the space between the floor and the slab in a structure such as a normal apartment.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a drainage system that can effectively reduce drainage noise and reduce the vertical dimension.

According to the first aspect of the present invention, there is provided a predetermined drop from each of the plurality of storage chambers for temporarily storing the drainage discharged from the water- circulating device, the communication conduits that communicate with the storage chambers, and the partitioned storage chambers. Accordingly, the present invention relates to a drainage system including a siphon drainage pipe connected to a drainage discharge part and a drainage introduction part connected to one of the storage chambers to introduce drainage from the water-circulating device.

  In the drainage system, the drainage discharged from the peripheral equipment flows into one of the plurality of storage chambers. The drained water that flows in is stored in the storage chamber and flows into a siphon drain pipe that communicates with the storage chamber.

  When a siphon drain pipe communicating with the one storage chamber (hereinafter also referred to as “one siphon drain pipe”) is filled with drainage, in the siphon drain pipe, the drainage in the drooping portion falls due to gravity. Therefore, a suction force corresponding to the water head difference in the drooping portion, that is, a siphon force, is generated inside the horizontal portion. The drainage in the horizontal part is sucked toward the drooping portion by the siphon force and becomes a so-called full flow in which the inside of the siphon drainage pipe is filled with drainage and flows down in the siphon drainage pipe toward the drainage standpipe. The generation of siphon force in the siphon drain pipe and the subsequent full flow flow are hereinafter referred to as “siphon phenomenon”.

  On the other hand, in the other storage chamber that communicates with the one storage chamber through the communication channel, the waste water overflowing from the one storage chamber flows in through the communication channel. It is discharged from a siphon drain pipe (hereinafter referred to as “other siphon drain pipe”) communicating with the room.

  Accordingly, the siphon phenomenon continuously occurs only in the one siphon drain pipe. In the other siphon drain pipe, only the overflow drained from the one storage chamber is discharged, and the amount is overwhelming compared to the amount of drainage flowing into the one storage chamber. small. Therefore, the siphon phenomenon hardly occurs in the other siphon drain pipe, and the air in the other storage chamber flows into the drainage discharge portion through the other siphon drain pipe. As a result, the siphon force in the one siphon drain pipe is alleviated, so that it is possible to prevent drainage noise from being generated due to the air trapped in the drainage in the one siphon drain pipe.

Also, if the capacity of the one storage chamber is set to be sufficiently small with respect to the flow rate of the wastewater discharged from the peripheral equipment, the siphon phenomenon occurs in the one siphon drainage pipe after the wastewater flows into the storage chamber. Can be shortened. Furthermore, when the water level of the one storage chamber to which the drainage introduction unit is connected rises, a siphon phenomenon occurs in the siphon drainage pipe communicating with the one storage chamber. The time until siphoning occurs in the tube can be greatly reduced. In addition, in the drainage system, since the storage chamber is partitioned into two or more water storage compartments by a partition member, the siphon phenomenon occurs only in the siphon drain pipe connected to the water storage compartment into which drainage flows from the bathroom. Hair and lint in the bathroom flows into the water storage compartment, is sucked into the siphon drain pipe, and flows vigorously toward the drainage standpipe. Therefore, clogging of hair and lint is less likely to occur.

  Here, examples of the drainage introduction unit include a trap for discharging the wastewater of the kitchen unit, a miscellaneous drainage pipe for discharging the wastewater from the unit bath, and a floor trap for introducing the wastewater from the washing machine.

  The siphon drainage pipe is connected to the drainage discharge part with a predetermined drop from the storage chamber. The siphon drain pipe is disposed along the slab from the storage chamber, for example, and can be suspended from the middle toward the drain discharge section, but is not limited to this form. Therefore, the siphon drain pipe may be provided with an ascending slope or a descending slope in the middle, and when there is a beam on the slab, it may be bent up and down so as to straddle the beam.

  Here, the drainage section is a destination where drainage is drained through the siphon drainage pipe. Specifically, the drainage section is drained from a drainage stand provided through the slab, and discharged from each peripheral device. There are drainage storage tanks that temporarily store wastewater, and sewers. Therefore, the siphon drainage pipe may be connected to a drainage vertical pipe, may be connected to a drainage storage tank, or may be directly connected to a sewer.

The invention according to claim 2 temporarily stores the drainage discharged from the water-circulating device and is divided into a plurality of storage chambers by a partition member having a height lower than the side wall , and the partition member and ceiling of the storage chamber A communication channel that is formed between the plate and communicates with each storage chamber, a siphon drain pipe that is connected to the drainage discharge portion with a predetermined drop from each of the partitioned storage chambers, and different water-circulating devices And a drainage introduction unit connected to each of the partitioned storage chambers .

In the drainage system, for example, a miscellaneous drain pipe from a bathroom is connected to a first storage chamber among the partitioned storage chambers, and a kitchen is provided in a second storage chamber adjacent to the first storage chamber. As the traps from the unit are connected to the partitioned storage chambers, drainage introduction portions from different water-circulating devices are connected.

By using different water-circulating devices, the drainage is separately discharged into the first storage chamber and the second storage chamber, so that each siphon drain pipe is used at substantially the same frequency. Therefore, the inside of the siphon drain pipe can be kept clean.

  In the drainage system, a plurality of storage chambers are communicated with each other through a communication pipe line, or a storage chamber having a low height is divided into a plurality of walls with the same height as the side wall. Each section communicates with a communication pipeline. Therefore, even when the space between the floor surface of the unit bath and the slab is not always sufficient, the water storage capacity can be secured, so that a large amount of drainage is discharged at a time as when draining from the bathtub of the unit bath. Even in the case, the discharged waste water does not overflow.

The invention according to claim 3 temporarily stores the drainage discharged from the water-circulating device and is divided into a plurality of storage chambers by a partition member having a height lower than the side wall, and the partition member and ceiling of the storage chamber A communication channel that is formed between the plates and communicates with each of the storage chambers, a siphon drain pipe that is connected to the drainage discharge portion with a predetermined drop from each of the partitioned storage chambers, and the partitioned Connected to one of the storage chambers and connected to a drainage introduction section for introducing drainage from the water-circulating device, a storage chamber branched from the siphon drainage pipe and connected to the siphon drainage pipe, and And a vent pipe that opens to a height lower than the communication channel in the storage chamber. The invention of claim 5 is directed to the siphon drain pipe, wherein each siphon drain pipe is branched from the siphon drain pipe. The drainage system according to any one of claims 1 to 3, further comprising a vent pipe communicating with a storage chamber to which a pipe is connected, wherein the vent pipe opens at a lower height than the communication channel. About .

  In the drainage system, when the water level of the storage chamber is high, the opening of the vent pipe is submerged below the surface of the water, and the drainage is discharged in a full flow in the siphon drainage pipe. Therefore, the waste water can be treated at a high speed with almost no drainage sound. When the water level in the storage chamber is lowered and the water surface is positioned below the opening of the vent pipe, air is sucked from the vent pipe and the siphon force in the siphon drain pipe is reduced. It is possible to particularly effectively reduce the generation of drainage sound due to simultaneous suction.

The invention according to claim 5 relates to the drainage system according to any one of claims 1 to 4, wherein a plurality of drainage introduction parts are connected to a storage chamber to which the drainage introduction part is connected.

  By connecting a plurality of drainage introduction sections to one storage chamber, the number of storage chambers can be reduced as compared to connecting the drainage introduction section to each storage chamber.

  The present invention further includes a drainage introduction part for discharging wastewater from the water supply equipment, a storage chamber for temporarily storing wastewater discharged from the drainage introduction part, and a wastewater in which the water supply equipment is installed from the storage chamber. A siphon drain pipe extending to a drainage vertical pipe penetrating the floor in the vertical direction, wherein the siphon drainage pipe is connected to the drainage vertical pipe with a drop from a predetermined position in the drainage system. A drainage joint for connecting the drainage pipe and the siphon drainage pipe, the base body to which the drainage introduction part is connected, and a connection part to which the siphon drainage pipe is connected to the base body, wherein the base body has a separation wall The drainage joint is divided into a plurality of sections.

Since the drainage joint can be configured without using an increaser or reducer, the possibility of water leakage can be greatly reduced. Moreover, since the connection position of the siphon drain pipe can be lowered, it can be stored under the floor. Furthermore, since it is not necessary to pipe the siphon drain pipe with a gradient, the pipe becomes simple and the workability is improved.

  In addition, in the joint for drainage, when dust is clogged, the lid is removed when the base body has a lid that can be opened and closed, otherwise, it is between the drainage introduction section. The dust inside can be easily removed by disconnecting. Therefore, the joint for drainage is suitable as a joint for a drainage system for a water-related device in which raw dust is often discharged together with drainage, such as a kitchen unit.

  Further, in the drainage joint, a separation wall is provided inside the base so as to separate a portion to which the siphon drain pipe is connected, and the upper part of the separation wall is opened or opened at the upper part of the separation wall. Each room communicates as if a section is provided. Therefore, the waste water from the water supply device basically flows into only one chamber at the beginning. And a siphon phenomenon occurs in the siphon drain pipe connected to this chamber. For this reason, during continuous drainage, the siphon drain pipe connected to the other chamber is almost empty, preventing excessive siphon force from being generated in the siphon drain pipe to prevent trap sealing and drainage noise. Is done.

  On the other hand, when draining the drainage, the siphon drainage pipe communicating with the one chamber is insufficient in processing capacity, so that the drainage gets over the internal separation wall and accumulates in another chamber adjacent to the one chamber. It is also drained from a siphon drain pipe that communicates with other chambers. Accordingly, there is no shortage of processing capacity even in the case of drainage.

  As described above, according to the present invention, there is provided a drainage system that can effectively prevent the occurrence of significant noise during drainage, can be reduced in vertical dimension, and can be easily disposed under the floor of an apartment or the like. Is done.

1. Embodiment 1
Next, an example of the drainage system of the present invention will be described.

  As shown in FIG. 1, a drainage system 100 according to the first embodiment is mounted on a drainage stand 9 that extends vertically through a slab 52 and a floor surface 6 that constitutes a drainage floor together with the slab 52. The drainage pipe 7 from which the drainage from the unit bath 20 is placed, the siphon drainage pipe 4 and the siphon drainage pipe 5 for introducing the drainage discharged to the miscellaneous drainage pipe 7 into the drainage vertical pipe 9, and the siphon drainage pipe 4 and a siphon drain pipe 5 and a chamber 11 for connecting the miscellaneous drain pipe 7. The miscellaneous drain pipe 7 and the chamber 11 correspond to the drain introduction part and the storage chamber in the present invention, respectively.

  The siphon drain pipe 4 and the siphon drain pipe 5 communicate with the horizontal portion 4A and the horizontal portion 5A extending along the slab 52 toward the drainage stand 9 and the horizontal portion 4A and the horizontal portion 5A. A hanging part 4B and a hanging part 5B hanging along the tube 9 are provided. The ends of the drooping portion 4B and the drooping portion 5B are provided below the slab 52 of the drainage standpipe 9 and join the drainage standpipe 9 at a confluence joint 9A having a conical shape that shrinks downward. A trap 7 </ b> A is provided at the entrance of the miscellaneous drain pipe 7.

  As shown in FIG. 2A and FIG. 4A, in the drainage system 100, the interior of the chamber 11 may be divided into two small chambers 11a and 11b by a partition member 12, and in FIG. As shown, two chambers, a chamber 11A and a chamber 11B, may be provided, and the chamber 11A and the chamber 11B may be communicated with each other through a communication pipe 13 in the vicinity of the ceiling. Hereinafter, the drainage system of the former aspect is referred to as “Aspect A”, and the drainage system of the latter aspect is referred to as “Aspect B”. In the drainage system of the aspect A and the aspect B, the chamber 11, the chamber 11A, and the chamber 11B all have a detachable ceiling plate. However, in FIG. 2 and subsequent figures, the internal structure of these chambers is shown. The ceiling board is omitted.

  In the drainage system of aspect A, the partition member 12 is a partition wall having a height lower than that of the side wall of the chamber 11. Therefore, there is a gap between the ceiling surface of the chamber 11 and the partition member 12. This gap corresponds to the communication channel of the present invention. Further, the small chamber 11a and the small chamber 11b in the aspect A, and the chamber 11A and the chamber 11B in the aspect B correspond to the storage chamber of the present invention, and among these, the small chamber 11a and the small chamber 11b correspond to the water storage section. The communication pipe 13 in the aspect B also corresponds to the communication flow path of the present invention.

  In the drainage system of aspect A, the miscellaneous drain pipe 70 and the siphon drain pipe 4 are connected to the small chamber 11a, and the siphon drain pipe 5 is connected to the small chamber 11b. On the other hand, in the drainage system of aspect B, the miscellaneous drain pipe 70 and the siphon drain pipe 4 are connected to the chamber 11A, and the siphon drain pipe 5 is connected to the chamber 11B. The siphon drain pipe 4 and the siphon drain pipe 5 are connected to the chamber 11, the chamber 11A, or the chamber 11B in the horizontal portion 4A and the horizontal portion 5A, respectively. In this embodiment, the small chamber 11a and the small chamber 11b, and the chamber 11A and the chamber 11B have the same volume. However, the small chamber 11a and the chamber 11A on the side to which the miscellaneous drain pipe 7 is connected are separated from each other. If the volume is smaller than the small chamber 11b and the chamber 11B on the side to which the drain pipe 7 is not connected, the time until the small chamber 11a and the chamber 11A are filled with drainage from the miscellaneous drain pipe 7 can be shortened. A siphon phenomenon occurs in the siphon drain pipe 4 in a shorter time, and the drainage flow rate can be raised. On the contrary, if the volume of the small chamber 11a and the chamber 11A is larger than that of the small chamber 11b and the chamber 11B, the siphon effect can be generated not only in the small chamber 11a and the chamber 11A but also in the opposite small chamber 11b and the chamber 11B. In the siphon drain pipe 4 and the siphon drain pipe 5, the inside can be maintained in a clean state by the self-cleaning action.

  In the drainage system of aspect A, as shown in FIG. 3A, the vent pipe 14 is branched from the horizontal part 4A of the siphon drain pipe 4 and communicated with the small chamber 11a, and the horizontal part 5A of the siphon drain pipe 5 is connected. The vent pipe 15 may be branched to communicate with the small chamber 11b. Also in the drainage system of aspect B, as shown in FIG. 3B, the vent pipe 14 is branched from the horizontal portion 4A of the siphon drain pipe 4 to communicate with the chamber 11A, and the horizontal section of the siphon drain pipe 5 is connected. The vent pipe 15 may be branched from 5A to communicate with the chamber 11B. In the embodiment in which the vent pipe 14 and the vent pipe 15 are provided, the opening positions of the vent pipe 14 and the vent pipe 15 are lower than the upper edge of the partition member 12 as shown in FIG. preferable.

  Furthermore, in the drainage system of the aspect A, as shown in FIG. 4B, washing drainage from a trap 70 or a washing machine of a water-related device other than the unit bath 20, for example, a kitchen unit (not shown). A floor trap (not shown) or the like to be discharged may be connected to the small chamber 11b so that drainage from water-related devices other than the unit bath 20 such as the kitchen unit or the washing machine is introduced into the small chamber 11b. . In addition, as shown in FIG. 4 (C), a thick miscellaneous drain pipe 7 from the unit bath 20 is connected to the small chamber 11a, and a thin drain pipe 72 from a water-related device with a small amount of drainage such as a sink is connected to the small chamber 11b. May be.

  Further, in the drainage system in which the vent pipe 14 and the vent pipe 15 are provided in the aspect A, as shown in FIG. 5, the miscellaneous drain pipe 7 of the unit bath 20 is in the small chamber 11a, and the trap 70 of the kitchen unit is in the small chamber 11b. You may connect to. 5A shows the configuration of the chamber 11 and its vicinity in the drainage system of the above aspect, FIG. 5B shows the chamber 11 and its vicinity from the direction of (A), and FIG. 5C shows the configuration of (A). From the direction, (D) shows a view from the direction of (c).

  Hereinafter, the operation of the drainage system 100 will be described by taking the drainage system of the aspect shown in FIG. 5 as an example. 6 to 10, the siphon drain pipe 4 and the siphon drain pipe 5 are depicted as extending in opposite directions, but this is for convenience of explanation, The siphon drain pipe 4 and the siphon drain pipe 5 extend in parallel to each other.

  As shown in FIG. 6A, the drainage discharged from the unit bath 20 is introduced into the small chamber 11 a of the chamber 11 through the miscellaneous drainage pipe 7. And the siphon drain pipe 4 is also filled with the waste_water | drain introduce | transduced into the small chamber 11a.

When the small chamber 11a and the siphon drain pipe 4 are filled with drainage, as shown in FIG. 6B, a siphon phenomenon occurs in the siphon drain pipe 4, and the drainage of the small chamber 11a is rapidly discharged. The waste water overflowing from the air passes through the partition member 12 and is introduced into the small chamber 11b. The waste water introduced into the small chamber 11b is immediately discharged through the siphon drain pipe 5 as shown in FIG.
Further, while the opening of the vent pipe 14 is below the water surface, the drainage flows in the full flow in the siphon drain pipe 4 as well. In addition, since air is inserted from the siphon drain pipe 5 into the drainage vertical pipe 9, excessive siphon force does not occur in the siphon drain pipe 4 while the full flow is generated in the siphon drain pipe 4. Generation of drainage noise is prevented.

  When drainage from the siphon drain pipe 4 progresses and the water surface in the small chamber 11a is below the opening of the vent pipe 14, air flows from the vent pipe 14 to the siphon drain pipe 4 as shown in FIG. Begins to be introduced. 8 (E), when the air introduced from the vent pipe 14 reaches the siphon drain pipe 4, the flow in the siphon drain pipe 4 becomes a mixed flow in which drainage and air are mixed. .

  When this is illustrated, as indicated by the alternate long and short dash line in FIG. 12B, the drainage flow rate rises rapidly in the siphon drainage pipe 4 and drainage from the miscellaneous drainage pipe 7 after drainage flows at the maximum flow rate for a while. As the amount of inflow decreases, the drainage flow rate gradually decreases. On the other hand, in the siphon drain pipe 5, as shown by a two-dot chain line, when the drain flow rate in the siphon drain pipe 4 reaches a peak, a slight drain flow rate is seen, but the drain flow rate in the siphon drain pipe 4 is a peak. After passing, the amount of drainage from the siphon drain pipe 5 becomes almost zero.

  Thus, in the drainage system 100, since the drainage flow rate does not vibrate, the generation of drainage noise is also prevented.

  Further, when drainage progresses and the opening of the vent pipe 14 is exposed on the water surface, the siphon force is reduced by the air introduced from the vent pipe 14, so that the flow inside the siphon drain pipe 4 just before the end of drainage. Becomes calm. Therefore, the generation of drainage noise due to abrupt suction of air and drainage into the siphon drain pipe 4 just before the end of drainage is prevented.

  Furthermore, since the siphon phenomenon occurs in the siphon drain pipe 4 when the small chamber 11a and the siphon drain pipe 4 are filled with drainage, as shown in FIG. 12B, drainage is introduced from the miscellaneous drain pipe 7. After that, the time until the drainage flow rate rises is greatly shortened.

  In contrast, in the drainage system that does not have the partition member 12 in the chamber 11, as shown in FIG. 9A, when drainage is introduced from the miscellaneous drainage pipe 7 into the chamber 11, As shown in B), a siphon phenomenon occurs in both the siphon drain pipe 4 and the siphon drain pipe 5. And even if drainage advances and the water surface falls, the vent pipe 15 and the vent pipe 14 are not necessarily exposed on the water surface at the same time. For example, the vent pipe 14 is exposed on the water surface first, As shown in (C), the vent pipe 15 is first exposed on the water surface. For example, when the vent pipe 15 is exposed first, air is introduced from the vent pipe 15 into the siphon drain pipe 5 and the drainage and air are mixed inside the siphon drain pipe 5 and are indicated by a two-dot chain line in FIG. As described above, the wastewater is intermittently discharged, and the sound of mixing the wastewater and air is heard through the vent pipe 15 to the outside. In addition, as indicated by the alternate long and short dash line in FIG. 8A, the drainage flow rate also vibrates significantly in the siphon drainage pipe 4, which also causes drainage noise.

  Furthermore, hair and lint are often discharged from the unit bath 20 and bathroom mixed with drainage. However, in the drainage system 100, as shown in FIG. It flows into the small chamber 11 b through the miscellaneous drain pipe 7 and is discharged to the siphon drain pipe 4 as it is. Therefore, the siphon drain pipe 4 and the siphon drain pipe 5 are hardly clogged.

  On the other hand, when the partition member 12 is not provided in the chamber 11, hair and lint are sucked from both the siphon drain pipe 4 and the siphon drain pipe 5 as shown in FIG. And it is easy to be caught so that the entrance part of siphon drain pipe 5 may be straddled. Therefore, the siphon drain pipe 4 and the siphon drain pipe 5 are likely to be clogged.

2. Embodiment 2
Hereinafter, another example of the drainage system of the present invention will be described. 13, the same reference numerals as those in FIG. 1 denote the same components as those shown in FIG.

  As shown in FIG. 13, the drainage system 102 according to the second embodiment is for treating drainage discharged from the kitchen unit 22 placed on the floor surface 6 constituting the drainage floor together with the slab 52. In the first embodiment, the joint 30 is used in place of the chamber 11 according to the first embodiment to connect the trap 70 for discharging the waste water from the kitchen unit 22 to the siphon drain pipe 4 and the siphon drain pipe 5. This is different from the drainage system 100 according to the above. The trap 70 corresponds to the drainage introduction part in the drainage system of the present invention.

  As shown in FIGS. 14 to 16, the joint 30 includes a base body 31 corresponding to the base body in the present invention, and a pipe body 32 and a pipe body 33 that correspond to the connection portion of the present invention and are erected on the side surface of the base body 31. With. Both the pipe body 32 and the pipe body 33 correspond to a connection portion in the present invention. The base 31 has a bottomed cylindrical shape and has a bottom 31a. A flange 31b extends outward along the radial direction outside the bottom 31a. In the first embodiment, the tube body 32 and the tube body 33 are provided at the same height, but may be provided at different heights.

  The siphon drain pipe 4 is connected to the pipe body 32, and the siphon drain pipe 5 is connected to the pipe body 33. It is preferable that the pipe body 32 and the pipe body 33 correspond to 20A, and steps 32a and 33a are respectively formed. When the siphon drain pipe 4 and the siphon drain pipe 5 are connected to the pipe body 32 and the pipe body 33, the siphon drain pipe 4 is inserted into the pipe body 32, the siphon drain pipe 5 is inserted into the pipe body 33, and the tip of the siphon drain pipe 4 is inserted. Is connected to the step 32a, and the tip of the siphon drain pipe 5 is brought into contact with the step 33a and adhered with an adhesive to make a watertight connection. A screw hole 31c or the like is drilled in the flange 31b so that it can be easily fixed to the floor surface 6. Needless to say, the pipe body 32 and the pipe body 33 do not necessarily have to be parallel, and may be installed in different directions in FIGS. 18 and 19.

  The base 31 is divided into two chambers 31A and 31B by a vertical separation wall 38 having a lower height than the base 31. The tops of the vertical separation walls 38 are released from the two chambers 31A and 1B and communicate with each other. . The tubular body 32 communicates with the chamber 31A, and the tubular body 33 communicates with the chamber 31B. Therefore, the vertical separation wall 38 corresponds to a partition member in the present invention, and the chamber 31A and the chamber 31B both correspond to a storage chamber.

  As shown in FIGS. 14 to 16, the vertical separation wall 38 may be erected in the center of the base 31 so as to equally bisect the inside of the base 31, and as shown in FIG. You may stand up close to one side of the base | substrate 31 so that a capacity | capacitance may become larger than the chamber 31B. Further, as shown in FIGS. 18 and 19, the vertical separation wall 38 may have a semi-cylindrical shape to partition the chamber 31B, and the capacity on the chamber 31A side may be increased. As shown in FIG. A cylindrical shape may be used to partition the chamber 31B and the chamber 31A.

  The shape of the base 31 of the present invention is not limited to a cylindrical shape, and may be a rectangular parallelepiped as shown in FIG. Moreover, as shown in FIG. 22, the form which piled up the cylindrical body 31d on the rectangular parallelepiped may be sufficient. By overlapping the cylindrical body 31d on the rectangular parallelepiped, for example, when the diameter of the trap 70 is 50A, the connection with the trap 70 becomes easier. In the example shown in FIGS. 21 and 22, the vertical separation wall 38 has the same form as the vertical separation wall 38 shown in FIGS. 18 and 19.

  In these examples, the end of the trap 70 is disposed so as to be located above the chamber 31A.

  Hereinafter, the operation of the drainage system 102 will be described.

  The drainage discharged from the kitchen unit 22 in the drainage system 102 is directed to the joint 30 through the trap 70. Then, the waste water introduced from the trap 70 first flows only into the chamber 31A. Then, the waste water flows into the siphon drain pipe 4 through the pipe body 32 connected to the chamber 31A. When the siphon drain pipe 4 is filled with drainage, a siphon phenomenon occurs and drains continuously.

  During continuous drainage, there is basically no water in the chamber 31B. Therefore, since the pipe body 33 and the siphon drain pipe 5 are basically empty, no air is sucked from the trap 70. Is reduced. In addition, since excessive siphon force is not applied to the trap 70, it is possible to prevent the seal 70 from running out of sealed water.

  On the other hand, in the case of the drainage drainage, the processing capacity is insufficient in the chamber 31A alone, so that the drainage passes over the top of the vertical separation wall 38 and accumulates in the other chamber 31B. Therefore, a siphon phenomenon occurs in two of the siphon drain pipe 4 and the siphon drain pipe 5, and the water is continuously drained.

  In the joint 30 according to the second embodiment, the pipe body 32 and the pipe body 33 have the same height and are erected in the vicinity of the bottom portion 31a. Further, both the siphon drain pipe 4 and the siphon drain pipe 5 can be arranged without any gradient. Therefore, even when the space between the floor surface 6 and the slab 52 is narrow, it can be easily installed, and the installation work does not take time.

  The drainage system of the present invention can be suitably applied to drainage discharged from water-related devices such as washing machines and washstands, in addition to kitchen units and unit baths.
