Description

  The present invention relates to a toilet drainage device.

Domestic wastewater generated in the house can be divided into wastewater from kitchens, bathtubs, washing machines, etc., and wastewater from toilets. Since the waste water from the kitchen, bathtub, and washing machine is not so sludge and does not mix much solids, for example, after gathering them under the floor in the house, etc. Or adopting a system that leads to the drain pipe.
On the other hand, toilet drainage has a high degree of sludge in itself and a high degree of contamination of paper and other solids. It is common to lead to a tube.
In general, domestic wastewater generated in a house is led to the outside by a drainage branch pipe from the house, and flows into a drainage main pipe outside through a drainage mass.

As a conventional toilet drainage device of this type, for example, there is a device disclosed in Japanese Patent Application Laid-Open No. 2005-163383.
As shown in FIG. 5, this toilet drainage device can be installed in an indoor drainage branch 2 and a curved sheath tube 3 from a flush toilet 1 that is an indoor drainage facility installed on a floor F of a toilet in a house A. It is configured to be connected to an outdoor drain main pipe 7 via a drainage mass 6 via a flexible pipe 4 and an outdoor drainage branch pipe 5 below the ground G of the house outdoor B. The curved sheath tube 3 penetrates the base portion 8 and protects the flexible tube 4. The indoor drainage branch 2, the curved sheath pipe 3, and the outdoor drainage branch 5 are all configured by rigid pipes such as polyvinyl chloride pipes.
As other conventional drainage devices, there are devices disclosed in Japanese Patent Application Laid-Open Nos. 2004-278095 and 2004-346513. These drainage devices connect the drain pipe from the house to the upper part of the drainage pipe (10) outside the house, and the lower drainage pipe (106) provided in the drainage pipe (10) has a downward outdoor drain main pipe (106 ) In the downstream direction.
JP 2005-163383 A JP 2004-278095 A JP 2004-346513 A

However, the apparatus described in Patent Document 1 uses a flexible tube 4 as shown in FIG. 5, but the flexible tube 4 is housed in a curved sheath tube 3 which is a hard tube. The actual drain pipe configuration is such that everything from the flush toilet 1 in the house A to the drain mass 6 in the house B is configured by connecting a plurality of hard pipes. That is, in this apparatus, for example, the entire length of the piping is configured by seven hard tubes (including the sheath tube 3) in the drawing, and three curved portions are configured in the entire length of the piping.
Therefore, in the drainage device of this patent document 1, since piping is performed by connecting a large number of hard (no dimensional freedom) pipes, the drainage passage from the flush toilet 1 to the drainage mass 6 of the outdoor B is practical. There is a problem that tends to be long. At the same time, in order to adjust the vertical step and the horizontal displacement between the flush toilet 1 and the drainage mass 6 in the outdoor area B with a hard tube, there is a problem that the number of bent portions must be increased.
The fact that the drainage passage is long and has a large number of bent parts means that the flow of drainage is more likely to stagnate, and in particular in the case of toilet drainage with a lot of solid matter, it is easy to cause clogging of piping, etc. was there. In order to solve this problem, if a large amount of water is allowed to flow all at once, the water level of the waste water stagnant in the pipe rises rapidly, causing a siphon phenomenon in the pipe, and the stored water in the toilet is piped. The problem is that the sealed water decreases due to being pulled by the water (so-called self-siphon phenomenon), and a large amount of drainage that has flowed suddenly flows into the outdoor drainage main 7 and flows backward to the upstream side of the outdoor drainage main 7 In addition to the problem of backflowing to other branch pipes connected to the outdoor drainage main pipe 7, there was also a problem against water saving of toilet drainage.
In addition, since the drainage device of Patent Document 1 is a pipe with a hard pipe, when repairing a fault in the pipe, even if a part of the pipe is cut and replaced, there is a dimensional adjustment or margin for reconnection. There was a problem that it could not be repaired easily, that is, a problem in maintenance. Of course, even when replacing only the problematic pipe among the plurality of pipes constituting the entire pipe, it is necessary to connect a new pipe to the pipes at both ends of the replacement with no positional freedom. There was a problem with difficult work.
In addition, in the drainage device of Patent Document 1, in order to connect the pipe to the drainage mass 6 in the outdoor B, the pipe is configured using a plurality of straight pipes and curved pipes. As long as is used, since the hard tube itself has a dimensional shape, there is a problem that the drainage mass 6 of the outdoor B of the house cannot be disposed in the vicinity of the house (in the vicinity of the foundation 8).

On the other hand, the drainage devices disclosed in the above Patent Documents 2 and 3 adopt a configuration in which piping is connected to the upper part of the drainage basin (10) from the interior of the house to the exterior of the house. The vertical drop in the drainage basin (10) is reduced. However, since many pipes (10) are connected by connecting a number of hard (no dimensional freedom) pipes to the outside of the house, the pipe distance tends to be substantially increased, and the bent part is As in the case of the drainage device disclosed in Patent Document 1, there is a problem as a toilet drainage facility that tends to be clogged with a lot of solids.
Of course, since it is a pipe made of a hard pipe, it is in a toilet drain pipe which tends to cause a failure, and there has been a maintenance problem similar to the case of Patent Document 1 in the pipe repair.
In particular, in the devices of Patent Documents 2 and 3, in order to install the drainage basin (10) outside the house in the vicinity of the house (near the foundation), the hard pipe led out of the house is made of a plurality of hard pipes. In addition, it must be configured to be connected to the drain (10) in a shape that is bent in the horizontal direction, and as a result, a pipe with a long passage length using many hard pipes and many curved parts. It has become. For this reason, as a toilet drainage apparatus, it is easy to produce the clogged failure, and it is an apparatus with many maintenance problems.

  Therefore, the present invention solves the above-mentioned conventional problems, and as a toilet drainage device, even if there are a lot of solids, it is difficult to clog, and even if there is a clogging failure, its repair and maintenance are easy, and even with a small drainage flow rate, it is smooth Therefore, it is an object of the present invention to provide a toilet drainage device that does not cause a backflow or a so-called self-siphon phenomenon even when a large amount of drainage flows, and that piping construction is easy and the cost can be reduced.

In order to achieve the above-described problems, the present inventor has conceived the present invention as a result of solving the above-mentioned problems with a completely different idea from the conventional toilet drainage system.
That is, the toilet drainage device of the present invention allows the drainage generated in the flush toilet installed on the floor surface of the house to be connected to the drainage main line with respect to the drainage main unit installed under the ground outside the house. A toilet drainage device that is introduced through a drainage mass provided,
A toilet drain outlet from the flush toilet is disposed on the flush toilet side, a toilet drain inlet is provided on the drain mass, and a toilet drain outlet on the flush toilet and a toilet of the drain mass The first feature is that the drainage inlet is directly connected to the drainage inlet by a drainage shooter made of a flexible tube.
Further, the toilet drainage device of the present invention provides drainage generated in a flush toilet installed on a floor surface in a house to the drainage main line with respect to a drainage main installed below the ground outside the house. A toilet drainage device that is introduced through a drainage mass,
A toilet drain outlet from the flush toilet is provided on the flush toilet side, and a toilet drain inlet is provided at the top of the drain mass and the toilet drain received from the toilet drain inlet is provided on the drain mass. A guide pipe in the drainage mass that leads downward in the drainage mass and discharges in the downstream direction of the drainage main pipe is provided, and between the toilet drainage outlet on the flush toilet and the toilet drainage inlet on the drainage mass Are connected directly by a drainage shooter made of a flexible tube.
In addition to the above second feature, the toilet drainage device of the present invention has a drainage shooter made of a flexible tube, which is provided with a toilet drainage outlet provided at the upper part of the toilet drainage outlet and drainage mass facing the floor from the flush toilet. In the plane including the mouth, the drooping upstream portion hanging from the toilet drainage outlet, the middle portion of the curve curved in a substantially horizontal direction from the drooping upstream portion, and the middle portion of the curve connected to the toilet drainage inlet The third feature is that it consists of three parts with a substantially horizontal downstream part.
In addition to the second or third feature, the toilet drainage device of the present invention has a plane including a toilet drainage outlet port that faces the floor from a flush toilet and a toilet drainage inlet port provided above the drainage mass. The drainage shooter is on a plane perpendicular to the partition wall of the foundation part that partitions the interior and exterior of the house, and is connected to the toilet drainage outlet that faces the floor from the flush toilet at one end. The fourth feature is that the end is connected to the toilet drain inlet at the top of the drainage mass.
Moreover, the toilet drainage device of the present invention, in addition to any of the above second to fourth features, the drainage shooter penetrates through the inside of the sheath pipe that is disposed through the base part that partitions the outside of the house, The fifth feature is that the curved shape of the drainage shooter is formed by the curved shape of the sheath tube while being extended from the interior of the house to the outdoor side of the house.
Further, in the toilet drainage device of the present invention, in addition to the fifth feature described above, the sheath tube is a substantially 90 degree curved sheath tube that penetrates the base portion in a direction perpendicular to the partition wall of the base portion that partitions the outside of the house. The drainage shooter that penetrates the sheath pipe is guided in the vertical and horizontal directions, and connected to the toilet drainage outlet and the toilet drainage inlet at the top of the drainage mass respectively. Is the sixth feature.

According to the toilet drainage device according to claim 1, drainage generated in the flush toilet installed on the toilet floor in the house flows into the drainage shooter from the toilet drainage outlet, passes through the drainage shooter, It flows into the toilet drain inlet of the drainage mass outside the house and is discharged toward the downstream of the main drainage.
The drainage shooter consisting of a flexible tube directly connects the toilet drainage outlet on the flush toilet side to the toilet drainage inlet of the drainage mass outside the house, thereby connecting multiple hard pipes to form a pipe Compared to the case, the degree of freedom of the passage configuration by the flexible tube is large, the drainage passage can be freely configured, and the drainage passage is short, has a small number of curves, and has few places that are bent sharply. Can be configured. Therefore, toilet drainage can be smoothly introduced into the external drainage main without clogging.

According to the toilet drainage device according to claim 2, drainage generated in the flush toilet installed on the toilet floor in the house flows into the drainage shooter from the toilet drainage outlet and passes through the drainage shooter. It flows into the toilet drainage inlet provided at the top of the drainage mass outside the house. The toilet drainage that flows into the toilet drainage introduction port is guided downward through the guide pipe in the drainage mass, and is discharged toward the downstream side of the drainage main pipe. The wastewater introduced into the drainage mass is guided by the guide pipe in the drainage mass and discharged toward the downstream direction of the drainage main, so that the flow of drainage is prevented from being disturbed, and the drainage flows into the drainage main. It is possible to prevent staying in the vicinity of the entrance and backflow in the vicinity of the entrance to the drain main and in the drain main.
When connecting a plurality of hard pipes by connecting directly from the toilet drain outlet of a flush toilet to the toilet drain inlet at the top of the drain mass outside the house with a drain shooter consisting of a flexible pipe Compared to the above, the degree of freedom of the passage configuration is large, and it is substantially the shortest distance and with one curve, or at most two curves (one time in the house and one time in the house), multiple curves. It becomes possible to constitute a drainage passage in which no part exists.
Therefore, it is possible to construct a smooth drainage passage with a very short curved portion with a flexible tube, and sufficiently solve the problems of the length of the passage distance and the frequency of bending that cause the toilet drainage to stagnate on the way. Further, it is possible to provide a toilet drainage device that can sufficiently reduce or eliminate the occurrence of clogging of toilet drainage due to solids or the like.
Further, in the toilet drainage device of the present invention, the drainage passage can be shortened at a short distance and the curvature thereof can be reduced to the minimum, so that toilet drainage can be smoothly guided to the drainage main of the drainage mass outside the house in a short distance. Therefore, without draining using a large amount of water, toilet drainage including toilet waste and used paper can be smoothly drained to the outdoor drainage mains using a small amount of water. In addition, the bent part of the drainage passage can be reduced, and since a large amount of water is not required, the overflow of toilet drainage due to the rise of the piping water level due to the so-called self-siphon phenomenon and the problem of backflow in the drainage main Disappear. Of course, the water storage tank of the toilet can be made compact with a small capacity, and the effect of saving water is great.
In the toilet drainage device of the present invention, the drainage shooter made of a flexible tube directly connects the toilet drainage outlet of the flush toilet in the house to the toilet drainage inlet on the upper drainage mass outside the house. There is an advantage that piping construction under the floor or under the ground can be greatly simplified as compared with a conventional structure in which a hard pipe is connected multiple times to form a drainage passage.
Especially in the repair work of piping when the piping is clogged in the middle, etc., in the conventional piping configuration with no flexibility, it is difficult to cut and reconnect a part of the piping. On the other hand, in the toilet drainage device of the present invention, it is possible to easily and easily perform the work of cutting and reconnecting a part of the drainage shooter made of a flexible tube. It becomes easy. Of course, in the case of the drainage shooter used in the present invention, the entire drainage shooter made of a flexible tube can be easily replaced.
Furthermore, the advantage of the toilet drainage device according to the present invention is that the drainage shooter made of a flexible pipe is connected directly from the toilet drainage outlet of the flush toilet to the toilet drainage inlet above the drainage mass, so that the vicinity of the outdoor area Even when a drainage mass is installed in the vicinity of the foundation, it is possible to connect pipes that have gone out of the house at the shortest distance and without bending parts without complicated detours and extensions. It is. In the conventional apparatus, piping with no bent portion could not be made with respect to the drainage mass installed in the vicinity of the base portion.

According to the toilet drainage device according to claim 3, in addition to the effect of the configuration according to claim 2, the drainage shooter made of a flexible pipe is provided on the same plane on the drooping upstream from the toilet drainage outlet. It is connected to the toilet drain introduction port of the drainage mass outside the house through the three parts of the part, the curved middle part that follows, and the substantially horizontal downstream part that follows. Accordingly, the wastewater generated by the flush toilet first flows down in the drainage shooter on one vertical plane in the drooping direction, then flows in the horizontal direction, and further flows in a substantially horizontal direction to reach the drainage mass. It can be drained with a very simple flow consisting of two flow operations.
That is, according to the toilet drainage device of the third aspect, since the connection is made by the drainage shooter comprising three parts of the vertical upstream part, the curved middle part and the substantially horizontal downstream part in the same plane, it is very simple and short. With the structure of the drainage passage of the distance, it becomes possible to ensure a sufficiently smooth toilet drainage.

  According to the toilet drainage device according to claim 4, in addition to the effects of the configuration according to claim 2 or 3, the toilet drainage outlet of the drainage shooter and the flush toilet, the toilet drainage introduction port of the drainage mass, However, since it is configured on a plane perpendicular to the partition wall of the foundation part that partitions the outside of the house, it is possible to sufficiently simplify the structure of the toilet drainage device using a drainage shooter made of a flexible tube. The toilet drainage can be smoothly discharged without stagnation with a small amount of water with a sufficiently short and simple drainage passage.

According to the toilet drainage device of claim 5, in addition to the effect of the configuration according to any of claims 2 to 4, drainage comprising a flexible tube connected to the toilet drain outlet in the house. The shooter extends through the outside of the house through a sheath pipe disposed on the foundation, and is connected to the toilet drain outlet of the drainage mass. The drainage shooter, which is a flexible tube, is protected by a sheath tube when penetrating the foundation. Further, the curved shape of the middle portion of the drainage shooter is maintained in an appropriate state by the curved shape of the sheath tube, and a preferable passage shape as the drainage shooter can be maintained.
Therefore, according to the toilet drainage device of the fifth aspect, the drainage shooter is protected from penetration at the base portion by the sheath tube, and the preferable piping shape of the drainage shooter is maintained, so that a good toilet drainage is secured. be able to.

According to the toilet drainage device of claim 6, in addition to the effect of the configuration of claim 5, the sheath pipe penetrates in a direction orthogonal to the partition wall of the base portion that partitions the outside of the house. The drainage shooter is guided in the vertical and horizontal directions through the sheath tube and connected to the toilet drainage outlet and the toilet drainage inlet, respectively. Will be made. Then, by passing through the sheath tube curved by approximately 90 degrees, the sheath tube reliably retains the curvature of the drainage shooter at approximately 90 degrees, and also maintains the state of being reliably extended in the vertical and horizontal directions.
Therefore, according to the toilet drainage device according to claim 6, the drainage pipe can be configured in a state orthogonal to the partition wall of the foundation part that partitions the outside of the house, and in a state that is very easy to construct, and in the shortest distance and With one bend, the toilet drainage can flow smoothly and reliably to the drainage mass outside the house.

Embodiments of the present invention will be described in more detail with reference to the following drawings.
FIG. 1 is a diagram showing an overall configuration of a toilet drainage apparatus according to an embodiment of the present invention, FIG. 2 is an overall view of a drainage mass to which a drainage shooter is connected, and FIG. 3 is a longitudinal sectional view of the drainage mass to which a drainage shooter is connected. It is.

  First, referring to FIG. 1, the house A and the house outdoor B are partitioned by a wall W of the house and a partition wall (cloth foundation) C1 of the foundation C. A flush toilet 10 is installed on the floor F of the toilet in the house A. The flush toilet 10 is disposed in the vicinity of the wall W so as to contact the wall W of the house. On the flush toilet 10 side, a toilet drain outlet 11 is disposed so as to face the floor F from the flush toilet 10.

A drainage mass 30 is provided in the drainage main line with respect to the drainage main pipe 20 installed under the ground G of the house outdoor B. More specifically, a drainage mass 30 is provided standing on the drainage main pipe 20. The drainage mass 30 and the drainage main pipe 20 are installed in the vicinity of the base part C, that is, in the vicinity of the partition wall C1 of the base part C.
A toilet drain introduction port 31 is provided at the top of the drainage mass 30.

A drainage shooter 40 directly connects the toilet drainage outlet 11 of the flush toilet 10 and the toilet drainage inlet 31 above the drainage mass 30.
The drainage shooter 40 penetrates the sheath tube 50 in the middle thereof.
The sheath tube 50 is disposed through the base portion C and the partition wall C1 of the base portion C.

2 and 3, the drainage mass 30 is provided with a drainage mass guide pipe 32 connected to and connected to the toilet drainage introduction port 31. The toilet drain received from the toilet drain introduction port 31 is guided downward, and discharged from the lower discharge port 32a toward the downstream of the drain main 20. The discharge port 32 a is opened obliquely downward toward the downstream side of the drainage main pipe 20.
The drain main 20 is provided as a continuous pipe by being connected to the drain main connection port 33 of the drain mass 30 at the lower part of the drain mass 30. The drainage mass 30 is held in a standing state on the drainage main pipe 20. The drainage mass 30 is buried in the ground G in a standing state, and the lid 34 is exposed to the ground G.

The drainage shooter 40 is composed of a flexible tube, and can be expanded and contracted and bent. The inner surface of the flexible tube constituting the drainage shooter 40 is a smooth surface so that the drainage passing through the interior flows smoothly and solids or the like are not easily restrained.
The drainage shooter 40, the toilet drainage outlet 11 of the flush toilet 10 to which the drainage shooter 40 is connected, and the toilet drainage inlet 31 above the drainage mass 30 are on a plane perpendicular to the partition wall C1 of the foundation C. It is configured. Therefore, the sheath pipe 50 made of a hard pipe such as a vinyl chloride pipe is also formed on the plane perpendicular to the partition wall C1.

When the base tube C and the partition wall C1 are constructed of concrete or the like, the sheath tube 50 is installed by forming a through-hole through which the sheath tube 50 penetrates at the same time, or in a state where the sheath tube 50 itself is penetrated. You may make it comprise and construct the foundation part C and the partition wall C1 together.
The sheath tube 50 is a tube slowly curved to 90 degrees (including approximately 90 degrees), and in a state of passing through the base portion C, one end faces upward in the vertical direction with respect to the under floor of the house A, and the other end is It arrange | positions so that it may face a horizontal direction (a substantially horizontal direction is included) from the partition wall C1 to the outdoor B of a house. And the toilet drain outlet 11 of the flush toilet 10 is disposed so as to protrude below the floor in the direction directly above one end of the sheath tube 50, and the drain mass 30 is disposed in front of the other end of the sheath tube 50. A toilet drain introduction port 31 is arranged.
One reason for providing the toilet drain introduction port 31 at the upper part of the drainage mass 30 is that when the toilet drain introduction port 31 is provided at the lower part of the drainage mass 30, the position of the toilet drain introduction port 31 is too low, Because the toilet drain introduction port 31 cannot be arranged at the same level as the sheath pipe 50 that penetrates the base C to the outdoor B, the drainage shooter 40 extended to the outdoor B is curved and connected at the outdoor B. Because you have to.

The drainage shooter 40 is connected to the toilet drainage outlet 11 and hangs down (including a substantially hanging direction), and a drooping upstream portion 41 and the drooping upstream portion 41 following the hanging upstream portion 41 in a horizontal direction (including a substantially horizontal direction). ) And a horizontal (including substantially horizontal) downstream portion 43 connected to the toilet drain introduction port 31 following the curved middle portion 42.
The bending middle portion 42 penetrates through the inside of the sheath tube 50 that is disposed so as to penetrate the base portion C, so that the shape is determined to be a 90-degree curved shape formed by the sheath tube 50 at the portion. Therefore, by setting the curvature of the curved shape of the sheath tube 40 in a state in which toilet drainage can easily flow, the curved shape of the drainage shooter 40 made of a flexible tube can be reliably held in a curved shape in which toilet drainage can easily flow. .
With the configuration of the drainage shooter 40 as described above, the drainage passage of the toilet is separated from three portions of the vertical upstream portion 41, the curved middle portion 42, and the horizontal downstream portion 43 on a plane orthogonal to the partition wall C1 of the base portion C. A drainage branch from the flush toilet 10 to the drainage mass 30 of the house outdoor B can be obtained with a very simple and short-distance drainage passage that is short distance and consists of only one curve.

  Of course, since the drooping upstream portion 41 and the horizontal downstream portion 43 of the drainage shooter 40 are outside the sheath tube 50 and are exposed without being covered by the hard tube, the drooping upstream portion 41 and the horizontal downstream portion 43 are configured. The position error with the toilet drain outlet 11 and the toilet drain inlet 31 can be easily absorbed in a state where the degree of freedom is large and the adjustment of the lengths in the long and short directions and the displacement adjustment in the vertical and horizontal directions is easy. Also, when repairing the piping, even if a part of the drainage shooter 40, which is an exposed flexible pipe, is cut out and replaced with another flexible pipe or another pipe, the positions of the cut off both ends By appropriately advancing or retreating, the replacement pipe can be easily connected.

The curved shape of the drainage shooter 40 and the curved shape of the sheath tube 50 are not necessarily 90 degrees (including substantially 90 degrees). A curved shape having a bending angle smaller than 90 degrees can be obtained.
Further, the plane including the drain shooter 40, the toilet drain outlet 11, the toilet drain inlet 31, and the sheath tube 50 does not necessarily need to be a plane orthogonal to the partition wall C1 of the foundation C. A plane that obliquely crosses the partition wall C1 is also possible. Such a case occurs, for example, when the flush toilet 10 in the house A and the drainage mass 30 in the house B are not at the shortest distance across the partition wall C1 of the foundation C. By disposing the sheath tube 50 so as to penetrate obliquely with respect to the partition wall C1 of the base portion C, the drainage shooter 40 penetrates the sheath tube 50 and penetrates the partition wall C1 obliquely, and the same The drainage shooter 40, the toilet drainage outlet 11 and the toilet drainage inlet 31 can be arranged on a plane, and a toilet drainage passage having a simple curved shape can be configured at a short distance.

  The sheath tube 50 is not always necessary when considering only the drainage function. When the drainage shooter 40 made of a flexible tube penetrates the foundation C, the protection means, for example, a member that protects and reinforces the periphery of the drainage shooter 40, and the drainage shooter 40 slowly under the floor F of the house A The function similar to that of the sheath tube 50 can be achieved by using a curved holding means for holding the curved shape, for example, a curved holding guide. The first and second features of the present invention are configurations including such a case.

  In the above embodiment, the drainage shooter 40 made of a flexible tube is used, and the toilet drainage inlet 31 of the flushing toilet 10 in the house A is used by using the drainage mass 30 provided with the toilet drainage inlet 31. The drainage passage from the outlet 11 to the toilet drainage inlet 31 of the drainage mass 30 in the house outdoor B was configured with only one curved portion, thereby ensuring smooth drainage of toilet drainage. However, for example, even when there is a vertical step or horizontal displacement between the toilet drain introduction port 31 of the drainage mass 30 and the partition wall C1 penetrating position of the drainage shooter 40, the drainage shooter 40 made of a flexible pipe should be used. Thus, the passage from the toilet drain outlet 11 to the toilet drain inlet 31 can be configured with one curve in the house A and one curve in the house B. Is possible.

With reference to FIG. 4, another embodiment of the present invention will be described.
The toilet drainage apparatus according to this embodiment is provided with a toilet drainage inlet 310 at the lower part of the drainage mass 30, and a drainage shooter 400 made of a flexible tube is connected to the house drainage outlet 11 on the flush toilet 10 side of the house A from the house. It leads to the outdoor B and is further connected to a toilet drainage inlet 310 below the drainage mass 30. The toilet drainage that has entered the toilet drainage inlet 310 is discharged toward the downstream side of the drainage main pipe 20 with a slight downward gradient.

4, members that perform the same functions as the members in the above-described embodiment shown in FIGS. 1 to 3 are denoted by the same reference numerals, and description thereof is omitted.
In the case of the present embodiment, the drainage shooter 400 has the same configuration as the drainage shooter 40 described above in the house A. That is, the drooping upstream portion 410 connected to the toilet drain outlet 11 and the subsequent curved middle portion 420 are arranged so as to pass through the inside of the sheath tube 50. On the other hand, the configuration of the drainage shooter 400 in the outdoor B is different from the drainage shooter 40 described above.
That is, in the case of this embodiment, since the toilet drainage inlet 310 is provided in the lower part of the drainage mass 30 in the house outdoor B, the sheath tube 50 (drainage shooter 400) that penetrates the partition wall C1 of the foundation C is provided. The position of the toilet drainage inlet 310 is a position with a lower step compared to the through position. For this reason, the drainage shooter 400 is connected to the toilet drainage inlet 310 through the outdoor outdoor curved parts 441 and 442 in the outdoor part 440 of the house.
Therefore, in the case of this embodiment, the drainage shooter 400 connects the toilet drainage outlet 11 in the house A to the toilet drainage inlet 310 in the house B with a total of three bends. The number of times of the three times of bending increases the number of times of bending compared to the case of the toilet drainage device of the above-described embodiment shown in FIGS. It can be said that it is inferior from a viewpoint.
On the other hand, when the toilet drainage device of the present embodiment is compared with the conventional toilet drainage device in which the hard pipes shown in FIG. The drainage shooter by the flexible tube has a sufficient merit that the degree of bending in the two times of bending outdoors in the house can be smoothly connected without a sharp bent state. Of course, compared to the conventional toilet drainage device, the degree of freedom in designing and constructing the toilet drainage passage in each house having individual circumstances is great, and it becomes very easy to perform the design and construction.

  In each of the above-described embodiments, the drainage device using the underfloor pipe from the flush toilet 10 in the house A to the drainage mass 30 in the house outdoor B has been described. However, the pipe includes not only the underfloor pipe but also the floor pipe. Piping may be used.

It is a figure showing the whole toilet drainage composition concerning an embodiment of the present invention. It is a general view of a drainage mass to which a drainage shooter is connected. It is a longitudinal cross-sectional view of the drainage mass to which the drainage shooter was connected. It is a figure which shows the whole toilet drainage structure which concerns on other embodiment of this invention. It is a figure which shows the example of the conventional toilet drainage apparatus.
