［００３４］[Function] In the drainage basin of the invention described in claim 1, since the branch pipe connection port formed on the side of the drainage basin body is parallel to the main pipe side connection port, the projecting dimension to the side of the drain pipe connection side is is short, for example,
If there is a head difference between the branch pipe connection port and the drainage pipe from the building, connect one end of the elbow connection port to the branch pipe connection port via a pipe to adjust the height with another joint, for example, Connect one end of the elbow to the other end of this elbow via a pipe, and when connecting a drain pipe to the other end of this elbow, make sure that the connection of the drain pipe and the side of the drainage basin body The interval becomes shorter. [0012] In the drainage basin of the invention according to claim 2, in the drainage basin according to claim 1, the main pipe side connection port on the upstream side is higher than the main pipe side connection port on the downstream side, and the branch pipe connection The wastewater flowing in from the port will not flow back into the main pipe connection port on the upstream side. [0013] Embodiment The configuration of an embodiment of the present invention will be explained with reference to FIGS. 1 to 5. [0014121 is the drainage basin body, this drainage basin body 21
The cleaning spout tube 22 is formed into a substantially pipe shape, and a cleaning spout tube 22 with an open top surface is protruded from the upper part, and the opening edge of the cleaning spout tube 22 is formed as a cleaning spout tube connection socket 23 . [0015] This drainage basin main body 21 also has main pipe side connection ports connected to the drainage main pipe at both ends, for example, a receiving port 2.
4°25 is formed, and an inverted portion 26 is formed at the inner bottom by connecting the two main pipe side sockets 24 and 25 in a straight line. [0016] The invert portion 26 is formed at a position eccentric to one side from the center of the drainage basin body 21. [0017] Also, in the stepped portion 27 formed inside near the inner end of the main pipe side socket 24 on the upstream side of this drainage basin main body 21, the main pipe side socket 24 on the upstream side is connected to the main pipe side socket 24 on the downstream side. It is formed one step higher than the side socket 25. [0018]Furthermore, on the other side of this drainage basin main body 21, a branch pipe connection port, for example, a socket 28 is formed parallel to the main pipe side socket 24 and facing in the same direction as the main pipe side socket 24. is,
This branch pipe socket 28 is also formed one step higher than the main pipe side socket 25 on the downstream side. [0019] Note that a leg portion 29 having a horizontal lower edge is formed at the bottom of the drainage basin main body 21. [00201 In the figure, reference numeral 39 denotes a drainage main pipe, which is connected to the main pipe side sockets 24 and 25 of the drainage basin main body 21, respectively. [0021] Next, the operation of this embodiment will be explained. [0022] If there is a head difference between the branch pipe socket 28 of the drainage basin main body 21 and the drain pipe 30 from the building, as shown in FIGS. Connect using the joint. [0023] For example, one end socket 33 of the 90° elbow 32 is connected to the branch pipe socket 28 via the pipe 31 whose height is adjusted, and the pipe 3 is connected to the upwardly facing other end socket 34 of the elbow 32.
5, one end socket 37 of the elbow 36 is connected to the elbow 36, and the other end socket 38 facing the side of the elbow 36 is connected to the drain pipe 30 projecting substantially horizontally. [0024] Since the branch pipe socket 28 is parallel to the main pipe side socket 24, the distance between the side of the drainage basin main body 21 and the connection part of the drain pipe 30 is similar to that of a conventional drainage basin with a 90° dog-bent Y structure. can be made shorter than . [0025] Furthermore, since the main pipe side socket 24 on the upstream side is formed one step higher than the main pipe side socket 25 on the downstream side,
The wastewater flowing in from the branch pipe inlet 28 does not flow backward to the upstream side. [0026] Also, since the main pipe side socket on the downstream side of the branch pipe socket 28 is formed one step higher than the mouth 25, the wastewater flowing in from the main pipe side socket 24 on the upstream side flows into the branch pipe socket 28. There is no backflow to the side. [0027] In the above embodiment, one end socket 33 of the elbow 32 is connected to the branch pipe socket 28 via the pipe 31,
Although the one end socket 37 of the elbow 36 is connected to the upwardly facing other end socket 34 of the elbow 32 via the pipe 35, the present invention is not limited to this structure. One end of the elbow 32 can be connected, and one end of the elbow 36 can be directly connected to the other end socket 34 of the elbow 32 without connecting the pipe 35. [0028]Furthermore, the branch pipe connection port of the drainage basin body 21 is not limited to the socket 28, but may also be a socket. [0029] Also, as shown in FIG. 7, the drainage basin main body 21
The branch pipe connection port is the inlet 28, and the branch pipe cover port 28 has a 90
The connection fitting opening 41 integrally formed at one end of the elbow 40 can be rotatably fitted and connected via an O-ring (not shown). [00301 In this embodiment, an annular protrusion 42 forming an annular groove into which an O-ring is fitted is formed on the inner periphery of the connection fitting port 41 on the outer periphery. The elbow 40, in which the connection fitting port 41 is fitted and connected to the inlet 28 of the branch pipe connection port, is held in place by appropriate means. [00311 Furthermore, as shown in FIG.
It is also possible to use one branch pipe connection port as a port 28, and to connect a connection fitting port 46 formed at one end of the cheese 45 to the port 28 in a rotatable manner via an O-ring (not shown). [0032] The cheese 45 is formed into a substantially pipe shape, and has a connecting tube 47 with an open top surface protruding from the upper part, and a cleaning tube, a drain pipe, etc. can be connected to this connecting tube 47. Further, this cheese 45 has a connection port, for example, a receiving port 48 formed at the other end. [0033] This cheese 45 also has an annular protrusion 49 formed on the outer periphery that forms an annular groove into which an O-ring is fitted on the inner periphery of the connection fitting port 46, and is further fitted into the fitting 28 of the branch pipe connection port. The cheese 45 with the abutment 46 fitted and connected is prevented from being pulled out and held by an appropriate means. [0034]

If the dimensions are short and, for example, there is a head difference between the branch pipe connection port and the drainage pipe from the building, use another joint to adjust the height, such as connecting one end of the elbow directly to the branch pipe connection port. Or, when connecting via a pipe, connect one end of the elbow to the other end of this elbow directly or through a pipe, and connect a drain pipe to the other end of this elbow. The distance between the connecting part and the side part of the drainage basin body is shortened, and even if the space on the side of the drainage basin body on the drain pipe connection side is narrow, the drainage pipe can be easily connected. [0035] In the drainage basin of the invention according to claim 2, in the drainage basin according to claim 1, the main pipe side connection port on the upstream side is higher than the main pipe side connection port on the downstream side, so that the drainage basin is There is no backflow to the upstream side of the pipe.
