Description

The present invention relates to a drain trap and its piping for preventing the odor from a sewer pipe and the reverse flow of pests to the indoor side.

As a well-known drain trap pipe, for example, there is a drain trap pipe shown in FIGS. A conventional example of the drain trap pipe shown in FIGS. 18 to 20 will be described below with reference to the drawings.
The conventional drain trap pipe shown in FIGS. 18 to 20 includes a tank body, a first drain pipe, a trap body, a discharge port, and a second drain pipe described below.
The tank body is specifically a box body such as a wash bowl or a bathtub, and a drain outlet for drainage is opened on the bottom surface, and the tank body is attached to the wall surface using an attachment fitting or the like.
The first drain pipe is a pipe connected from the drain port of the tank body to a trap body described later.
The trap body is a box connected to the first drain pipe, and the odor and pest from the sewage side do not flow back to the indoor side by always storing drainage called sealed water inside. In this conventional example, the trap body is composed of a box body divided into two parts, an upper part and a lower part. Sealing water stored at a height up to the lower end of the outlet prevents odors and pests from flowing back from the sewer pipe.
The discharge port is a tube that discharges the waste water in the trap body to the outside of the trap body, and is configured to extend to the side surface of the trap body.
The second drain port is a pipe connected to the discharge port, and is finally connected to a sewer pipe configured in the wall surface.

The drain trap pipe configured as described above is assembled and constructed as follows.
The tank body is attached and fixed to the wall surface, and the first drain pipe is connected to the drain port of the tank body. Thereafter, a trap body in which a sealed cylinder is assembled in advance is connected to the lower end of the first drain pipe with a nut or the like. And after connecting a 2nd drainage pipe to the discharge port of a trap main body with a nut, a 2nd drainage pipe is inserted and connected to the opening of the sewer pipe arrange | positioned in the wall surface. When the second drain pipe is connected to the sewer pipe, the second drain pipe extending from the outlet of the trap body must be inserted into the sewer pipe that has been opened in advance. Therefore, the second drainage pipe from the outlet is finely adjusted so that the direction of the outlet of the trap body is on the wall (rear side) so that it can be properly connected to the sewage pipe. Connect the drainage pipes after aligning the drainage pipes and cutting the dimensions. In this way, the construction / assembly is completed.

The drainage trap pipe constructed in this way has the following drainage flow.
When drainage is generated in the tank body, the drainage is discharged from the drainage port of the tank body to the outside of the tank body. Then, it flows into the trap body through the first drain pipe from the drain port. The drainage in the trap body passes through the sealing tube and is drained from the outlet to the outside of the trap body. In addition, since the second drain pipe is connected to the discharge port, the drainage from the discharge port is discharged to the second drain pipe and finally drained from the second drain pipe to the sewer pipe.

The drain trap pipe as in the conventional example has the following problems.
When constructing the tank body, the first drain pipe, the trap body, etc., it is necessary to connect the second drain pipe extending from the outlet of the trap body to the sewer pipe opened in the wall surface. Since the opening position of the sewer pipe is preset and opened, it is necessary to connect the second drain pipe and the trap body associated therewith. This connection work is very difficult and often requires precise work. For example, the direction of the outlet of the trap body is adjusted toward the opening side of the sewer pipe, or the second drain pipe is connected to the outlet of the trap body. Cut to the length of the sewage pipe and make fine adjustments. By doing in this way, a 2nd drainage port can be connected to a sewer pipe in good condition. Such construction / assembly work is very troublesome for workers who perform construction and assembly.
In addition, the second drain pipe usually has to set a slope (hereinafter referred to as “drain slope”) in order to drain the waste water into the sewer pipe. Then, it is necessary to pipe while setting the gradient at the time of construction. In some cases, due to the positional relationship between the opening of the sewer pipe and the outlet of the trap body, the drainage gradient of the second drainage pipe may be reversed. If the person is unfamiliar or a beginner, the second drainage pipe may have a reverse slope, causing problems such as backflow of drainage and inability to drain smoothly.
Further, in the drain trap pipe in which the sewer pipe is arranged in the wall surface as in the prior art, since the discharge port of the trap body faces the wall surface side, the first drain pipe and the trap body Although the height can be adjusted, fine adjustment in the lateral direction of the sewage pipe from the outlet of the trap body is impossible because the two are directly connected by the second drain pipe.
In addition, the tank body is often attached to a cabinet that is conventionally called a cabinet and has a storage space that can store stored items. However, recently, due to the trend of improving the design of the whole room and the harmony of the design, The tank body is the mainstream. In such a tank body, since the first drain pipe, the second drain pipe, and the trap body are exposed to the indoor side, in particular, such first and second drain pipes and drain traps are exposed to the outside. In such a drainage pipe, the design of the drainage pipe and the drain trap itself had to be improved.

Further, in the case of the conventional example shown in FIG. 18 in particular, the displacement of the second drainage pipe and the sewer pipe is eliminated by connecting the outlet of the trap body and the second drainage pipe with a ball joint. Although there are some, if it is such a joint, if the height of the sewer pipe was high with respect to the height of the discharge port, the second drainage pipe often had a reverse slope.
In particular, in the case of the conventional example shown in FIG. 19, there are some which adjust the connection with the sewage pipe by shifting the central axis of the second drainage pipe. In such a pipe, the center of the second drainage pipe is used. Since only the position adjustment corresponding to the axis deviation width can be performed, a position deviation larger than the deviation width or a position deviation smaller than the deviation width cannot be dealt with.

Therefore, the drain trap pipe of the present invention has been invented to solve the following problems.
1. It must be very easy to assemble and install.
2. When assembling and constructing, it is easy to position the outlet.
3. The position of the second drain pipe and sewer pipe opening can be easily adjusted.
4). The second drain pipe should not have a reverse slope.
5. The design of the first drain pipe, the second drain pipe and the drain trap pipe should be good.

A first embodiment of the present invention will be described below with reference to the drawings.
The drain trap pipe of this embodiment shown in FIGS. 1 to 10 includes a tank body 1, a first drain pipe 3, a trap body 4, a discharge port 7, a second drain pipe 11, and a snap ring 14 described below. Is done.
As shown in FIGS. 3 to 5, the tank body 1 is specifically a box body such as a wash bowl or a bathtub, and a drain outlet 2 for drainage is opened on the bottom surface, and a mounting bracket or the like is used. And attached to the wall surface 17. In addition, a cylindrical convex portion 9 is configured to hang downward on the lower surface of the tank body 1.
The first drain pipe 3 is a pipe connected from the drain port 2 of the tank body 1 to the trap body 4 described later.
The trap body 4 is a box connected to the first drain pipe 3 as shown in FIGS. 1 and 2, and always stores a drainage called a sealed water part 6 in the inside of the trap body 4 from the sewage side. Odors and pests will not flow back into the room. In this conventional example, the trap body 4 is composed of an upper part and a lower part of a box, and a water seal cylinder 5 is constructed by being inserted into the trap body 4 through the first drain pipe 3 from the drain port 2. The spillage of odors and pests from the sewer pipe 16 is prevented by the sealing part 6 that is stored at a height from the lower end of the sealing cylinder 5 to the lower end of the discharge port 7 to be described later. Further, a concave portion 10 having a shape (cylindrical shape) matching the convex portion 9 of the tank body 1 is formed on the upper surface of the trap body 4. In addition, the said recessed part 10 is comprised in the location which can be positioned so that the center axis | shaft of the discharge port 7 mentioned later may become substantially parallel to the wall surface 17. FIG. In this embodiment, the concave portion 10 is formed at a location facing the discharge port 7 in the top view of the trap body 4.
The discharge port 7 is a tubular body that discharges the waste water in the trap body 4 to the outside of the trap body 4, and is configured to extend on the side surface of the trap body 4. In the present embodiment, as described above, the central axis of the discharge port 7 is arranged to be parallel to the wall surface 17 to which the tank body 1 is attached. Further, as shown in FIG. 7, the discharge port 7 constitutes a cut groove 8 into which a later-described snap ring 14 is inserted at two locations on the upper surface and the lower surface. The cut groove 8 is an outer peripheral surface of the discharge port 7 and forms a cut groove toward the side surface with respect to the central axis of the discharge port 7.
The second drain pipe 11 is a pipe connected to the discharge port 7, and is finally connected to the sewer pipe 16 configured in the wall surface 17. In the present embodiment, the second drain pipe 11 is bent as shown in FIG. Further, as shown in FIG. 6, a plurality of concave grooves 12 configured along the circumference are formed on the outer peripheral surface of the second drain pipe 11. In addition, the concave groove 12 is configured by forming a flat surface 13 at two locations where the second drainage pipe 11 becomes an upper surface and a lower surface during construction.
As shown in FIG. 8, the snap ring 14 is a C-shaped ring having at least the widths of the cut groove 8 and the concave groove 12, and forms a flat surface 13 at two lateral sides of the inner diameter of the ring.
In this embodiment, the second drain pipe 11 is inserted into the outlet 7 and the snap ring 14 is inserted into the cut groove 8 of the outlet 7 so that the flat surface 13 of the snap ring 14 and the second drain pipe 11 The flat surface 13 is fitted and connected so as to match. At this time, since the cutout groove 8 is formed in the discharge port 7 at two locations on the upper surface and the lower surface, the snap ring 14 cannot be inserted only from the side of the discharge port 7. Further, since the flat surface 13 of the second drainage pipe 11 and the flat surface 13 of the snap ring 14 do not match at the time of connection, the snap ring 14 cannot be inserted into the outlet 7 and the second drainage pipe 11. The flat surface 13 of the second drainage pipe 11 must be piped in accordance with the flat surface 13 of the snap ring 14 that can be inserted only laterally with respect to the outlet 7. If it does so, the 2nd drainage pipe 11 comprised in the upper part and the lower part of the 2nd drainage pipe 11 must also be positioned and piped together with the cut groove 8 of the discharge port 7, and finally finally in this state The snap ring 14 can be inserted into the cut groove 8, and the flat surface 13 of the snap ring 14 and the flat surface 13 of the second drain pipe 11 can coincide with each other, and both the second drain pipe 11 and the discharge port 7 can be matched. Can be connected. The second drain pipe 11 is connected to the discharge port 7 only after being positioned as described above. Accordingly, the position of the cut groove 8 of the discharge port 7 and the flat surface 13 of the second drain pipe 11 and the position of the flat surface 13 of the snap ring 14 are designed and arranged in advance so that a drain gradient is given to the second drain pipe 11 in advance. If this is done, the drainage gradient can be positioned and set simply by connecting the second drainage pipe 11 to the discharge port 7. Therefore, the second drainage pipe 11 can be piped without setting the drainage gradient during construction. it can.

The drain trap pipe configured as described above is assembled and constructed as follows.
The tank body 1 is attached and fixed to the wall surface 17, and the first drain pipe 3 is connected to the drain port 2 of the tank body 1. Thereafter, the trap body 4 in which the sealing cylinder 5 is assembled in advance is connected to the lower end of the first drain pipe 3 with a nut or the like. Even if the height of the first drainage pipe 3 is high as shown in FIG. 1, the length of the first drainage pipe 3 is cut at an appropriate location as shown in FIG. Thus, the height direction of the sewage pipe 16 opening and the discharge port 7 is adjusted in advance so as to be the optimum height. Further, the concave portion 10 of the trap body 4 is aligned with the convex portion 9 configured to hang down from the tank body 1, and the discharge port 7 of the trap body 4 is positioned and connected. As shown in FIGS. 3 to 5, the discharge port 7 is arranged so that the central axis is substantially parallel to the wall surface 17 to which the tank body 1 is attached.
Then, as shown in FIG. 9A, the second drain pipe 11 is inserted into the discharge port 7 of the trap body 4. At this time, the end of the second drain pipe 11 on the concave groove 12 side is inserted into the discharge port 7. Then, horizontal alignment is performed by cutting the end of the groove 12 so that the second drain pipe 11 can be inserted into the sewer pipe 16. Then, since the second drain pipe 11 is bent toward the wall surface 17, it can be connected to the sewage pipe 16 of the wall surface 17. Since the central axis of the discharge port 7 of the trap body 4 is configured to be parallel to the wall surface 17, the opening of the sewage pipe 16 is cut by appropriately cutting the discharge port 7 connecting end side of the second drain pipe 11. The horizontal position can be adjusted.
Then, as shown in FIG. 9B, the snap ring 14 is inserted into the cut groove 8 of the discharge port 7. At this time, the snap ring 14 inserted into the cut groove 8 as shown in FIG. 10 is inserted so as to match the concave groove 12 of the second drain pipe 11 in the discharge port 7. And it attaches so that the flat surface 13 of the snap ring 14 may slide and agree with the two flat surfaces 13 of the concave groove 12. As described above, since the second drain pipe 11 and the flat surface 13 of the snap ring 14 are matched, it is possible to perform positioning in the vertical direction, and the flat surface 13 of the snap ring 14 and the second drain pipe 11. Since it can connect so that it may not become a reverse gradient, it becomes unnecessary to set the drain gradient of the 2nd drain pipe 11 at the time of construction, and it does not need to pipe, and workability improved. In this way, the construction / assembly is completed.

The drainage trap pipe constructed in this way has the following drainage flow.
When drainage occurs in the tank body 1, the drainage is discharged out of the tank body 1 from the drain port 2 of the tank body 1. Then, it flows into the trap body 4 from the drain port 2 through the first drain pipe 3. Drainage in the trap body 4 passes through the sealing cylinder 5 and is drained out of the trap body 4 from the discharge port 7. Further, since the second drain pipe 11 is connected to the discharge port 7, the drainage from the discharge port 7 is discharged to the second drain pipe 11, and finally from the second drain pipe 11 to the sewer pipe 16. Drained.

In addition to the above-described embodiment, the drain trap pipe of the present invention has a cylindrical joint member 15 standing on the top of the trap body 4 as shown in FIGS. 13 to 14, for example. You may comprise from 4 to the height of the tank body 1. With such a configuration, since the height from the tank body 1 to the trap body 4 is shielded, the design is good. In particular, if the tank body 1 does not have a cabinet, the effect is particularly exerted.
Further, for example, as shown in FIG. 11 to FIG. 12, a cylindrical joint member 15 is erected from the lower part of the tank body 1 downward so that the height of the tank body 1 is reached from the trap body 4. Also good. With such a configuration, since the height from the tank body 1 to the trap body 4 is shielded, the design is good. In particular, if the tank body 1 does not have a cabinet, the effect is particularly exerted.
Further, the joint member 15 is configured to hang downward from the tank body 1 as shown in, for example, FIGS. 15 to 16 in addition to standing from the trap body 4, and further, sponge, rubber, etc. You may comprise from an elastic member. At this time, even if the joint member 15 is adjusted in the height direction of the trap body 4 from the tank body 1 by cutting or contracting / extending, the joint member 15 can be adjusted in accordance with the adjustment. Therefore, since no gap is generated in the height direction from the tank body 1 to the trap body 4, the design of the tank body 1 is improved.

In addition to the embodiments described above, the embodiments of the present invention can be modified as appropriate without departing from the scope of the claims.
For example, in the above-described embodiment, the convex portion is configured to hang downward from the tank body, and the concave portion corresponding to the convex portion is configured to the upper portion of the trap body. For example, the convex portion is configured to extend upward from the upper portion of the trap body. A concave portion that matches the convex portion may be formed on the bottom surface of the tank body. Since both configurations are configured to position the discharge port, there is no particular problem.

Further, in the embodiment of the present invention, the connection between the first drain pipe 3 and the trap body 4 is connected with a nut or the like. As shown in FIG. 17, for example, a watertight member 18 such as an O-ring or a flat packing is used. The connection may be made only through the network. By using such a pipe, both can be connected in a watertight manner by adjusting only the height direction of the first drain pipe 3 without performing a connection operation with a nut or the like as in the conventional example. In this case, since the second drain pipe 11 is connected and fixed to the sewer pipe, the second drain pipe 11 is inserted into the discharge port 7 of the trap body 4 and is connected and fixed in a watertight manner. The trap body 4 does not fall off from the first drain pipe 3.

Moreover, in the Example of this invention, although the tank 1 and the 1st drain pipe 3 are comprised by another part, even if the tank 1 and the 1st drain pipe 3 are comprised integrally like FIG. good. If comprised in this way, since it does not need to bother the connection of the tank body 1 and the 1st drainage pipe 3 conventionally, construction becomes very easy.
