The sink has a sink portion having a drain outlet on the bottom surface, a cabinet portion disposed below the sink portion, and a height 10 provided on a floor surface called a saddle portion provided below the cabinet portion. An underfloor pipe for discharging wastewater to the sewage side is formed in the underfloor space below the buttock, which is composed of a rising portion of around centimeters. The drain trap portion is a bottomed cylindrical member attached to the drain outlet of the sink, and has a discharge port on the bottom surface, and a pipe portion rises on the cylinder from the discharge port, above the pipe portion. From the top, a reverse one-shaped cylindrical member with a wall is fitted, and the drainage that collects downward from the upper end of the pipe part and the cylindrical member is called a sealed part in the drainage channel. The drainage pool is formed, and the drainage pooled in the sealed water prevents odors and pests from the sewage from flowing back to the indoor side. Further, the drain trap section is configured to connect the discharge port and the underfloor pipe section via the vertical pipe section, and the drainage of the drain trap section is discharged from the underfloor pipe to the sewage side. In the drainage pipe configured as described above, when drainage is performed in the sink, the drainage from the drainage port provided in the sink, through the vertical pipe part and the underfloor pipe connected to the vertical pipe part, Finally, it is discharged into sewage.
[0003]
Recently, in order to reduce the dead space in the cabinet and efficiently use the storage space, the sink is often provided with a drain pipe as shown in FIG . The piping structure of the conventional example shown in FIG. 8 is a drainage device having a cabinet, and shows a state where drainage piping is performed on the sink, and the sink, drainage elbow, drain trap part, described below, It consists of a vertical pipe. The sink has a sink portion having a drain outlet on the bottom surface, a cabinet portion disposed below the sink portion, and a height 10 provided on a floor surface called a saddle portion provided below the cabinet portion. An underfloor pipe for discharging wastewater to the sewage side is formed in the underfloor space below the buttock, which is composed of a rising portion of around centimeters. The drainage elbow is a bottomed cylindrical member attached to the drainage port of the sink, and has a discharge port on the side surface in the vicinity of the bottom surface in the direction toward the back of the cabinet. The drain trap part is a member having a tubular body bent into an S shape, and is disposed along the back surface of the cabinet of the sink. The upstream side of the drain trap part extends through a horizontal pipe part that is a tubular body extending in a substantially horizontal direction. Connected to the outlet of the drainage elbow, the downstream side is connected to the underfloor piping through a vertical pipe connected to the drainage trap. In the drainage pipe configured as described above, when drainage is performed in the sink, the drainage passes from the drainage port provided in the sink to the drainage port, the horizontal pipe part, the drainage trap part, and the vertical pipe part, It is finally discharged into sewage through the underfloor pipe connected to the vertical pipe. Further, in the case of the drainage pipe of the conventional example shown in FIG. 7 , the drainage trap and the vertical pipe portion that are piped through the center of the cabinet are replaced with the back plate of the cabinet according to the drainage pipe having the configuration shown in FIG. Therefore, there is an advantage that a larger article can be stored in the cabinet more efficiently in the cabinet.
[0004]
By the way, the drainage water is already used for some reason. For this reason, for example, if wastewater is used for washing dishes, etc. in a sink, cooking scraps, etc., and if wastewater is used in bathrooms, washstands, washing machines, etc., dust and hair are mixed in most cases. is doing. In the above drainage device, in order to prevent these dusts mixed in the drainage from being discharged into the drainage pipe, a drain plate is provided with a slit part to prevent the entry of large dusts, A strainer that collects dust and hair is arranged to remove dust from the wastewater, but it is impossible to remove dust completely, especially when large dust flows into the wastewater. The piping may be blocked. Even if the dust is not very large, if oil is mixed in the drainage, the oil will stick to the inner surface of the drainage pipe and grow as a large lump with the above dust attached, blocking the drainage pipe. May end up.
[0005]
If the drainage pipe is blocked due to the above reasons, etc., if the clogged part is a sealed part, the clogged part is exposed by removing the cylindrical member constituting the sealed part, etc. It is possible to remove the dust that causes the blockage of the piping.
In practice, however, pipe clogging occurs mostly downstream of the drain port, and in most cases it cannot be handled by the method of removing the extending tube member as described above. Therefore, a method called a can tool method or a high pressure cleaning method is used for clogging the pipes in these pipes.
[0006]
In the can tool method, the metal coil wire with flexibility is pushed into the drainage pipe from the drainage port and abuts against the dust at the pipe section, so that the dust is crushed into pieces and broken. Further, it is a method of eliminating the clogging in the drainage pipe by pushing it further downstream.
In addition, the high pressure washing method pushes a pressure resistant and flexible high pressure washing pipe into the drainage pipe from the drain outlet, and after the tip of the pipe reaches the clogged position, discharges water from the high pressure washing pipe at a high pressure. This is a method to eliminate clogging in the drainage pipe by crushing and sweeping the dust into pieces.
[0007]
[Problems to be solved by the invention]
However, in practice, the drainage pipe having only a vertical pipe portion as in the conventional example shown in FIG. 7 , the drainage pipe including many bent portions as in the conventional example shown in FIG. In this case, since there is a bent part of the pipe body such as a bent part in the path from the drain outlet to the dust, as shown in FIG. 9 , the coil wire of the can tool method or the high pressure washing pipe for high pressure washing However, there is a problem that the can tool method and the high-pressure cleaning method cannot be performed because it cannot reach the dust existing in the pipe beyond it by hitting the bent portion. The present invention has been invented in view of the above problems, and in a drainage pipe provided with a drainage trap portion disposed in a cabinet, the drainage pipe has a bent portion of a tubular body such as a bent portion. Furthermore, the present invention provides a drainage pipe that can eliminate clogging from the drainage port by a can tool method or a high pressure washing method.
