The inside of the housing 41 is divided into two in a semicircular cross section by the vertical portion 422 of the partition wall 42, while the flow passage 4 a is formed between the lower end edge of the vertical portion 422 and the bottom surface of the housing 41. Is formed. In addition, on the back surface side of the inclined portion 41 of the partition wall 42, an outflow port 4 b is formed on the upper portion of the rod body 41 over a substantially half circumference. For this reason, as will be described later, the waste water from the washing machine flows along the inclined portion 421 of the partition wall 42 into one space having a semicircular cross section of the rod body 41 and through the flow passage 4a. Reaches the other space having a semicircular cross section and overflows from the outlet 4b. Under the present circumstances, the sealing water by the waste_water | drain of the height which reaches the outflow port 4b from the bottom face can be ensured in the inside of the rod body 41 of the rod-shaped member 4.

  A stepped portion 41x that can be supported by the inner flange 211 of the lower cylindrical portion 21 of the connecting member 2 is formed on the upper outer peripheral surface of the casing 41 of the rod-shaped member 4.

  The elbow member 5 is an elbow-like tubular body formed of rubber or the like, and can be connected to a drainage hose (not shown) of a washing machine at one end thereof, and the above-described wrinkle-like member at the other end. An outer peripheral surface that can be fitted to the inner peripheral surface of the upper end portion of the four casings 41 is formed, and a protruding portion 51 that can be supported by the stepped portion 22x of the connecting member 2 is formed.

  The lock member 6 has a male screw 6m that can be screwed into the female screw 23f of the upper cylindrical body 23 of the connection member 2 described above, and is fitted into the elbow member 5 from the other end side.

  Next, the construction procedure of the drainage discharge unit 1 configured as described above will be described.

  First, an attachment opening Fa having a diameter larger than the outer diameter of the drain pipe P is formed in the floor board F in accordance with the installation position of the washing machine. Then, one end portion of the drain pipe P laid under the floor is raised so as to face the mounting opening Fa of the floor plate F. Next, an adhesive is applied to the inner peripheral surface of the upper end portion of the drain pipe P, and an adhesive is applied to the outer peripheral surface of the lower cylinder portion 21 of the connection member 2, so that the drain pipe P is connected to the lower cylinder portion 21 of the connection member 2. Is inserted until the flange portion 22 abuts on one end thereof, and the two are bonded together. When the bonding between the connection member 2 and the drain pipe P is completed, the connection member 2 is placed on the floor plate F, and the screw S is screwed through the screw hole 22a of the flange portion 22 to be fixed to the floor plate F. When the connecting member 2 is fixed, the decorative cover 3 is attached to the connecting member 2 and the outer cover surface of the upper tube portion 23 and the outer surface of the flange portion 22 are covered.

  Next, the rod-like member 4 is inserted into the drainage pipe P while being inserted into the connecting member 2, and the stepped portion 41 x is supported by the inner flange 211 of the lower cylindrical portion 21 in the connecting member 2. Further, the other end portion of the elbow member 5 to which the lock member 6 is attached is inserted into the upper end portion of the rod body 41 of the rod-shaped member 4 through the connection member 2, and the projecting portion 51 of the step portion 22x of the connection member 2 is inserted. To support. Thereafter, if the lock member 6 is screwed into the upper tube portion 23 of the connecting member 2, the elbow member 5 can be sandwiched between the connecting member 2 and fixed so as not to be detached.

  Thus, if the waste_water | drain discharge | emission unit 1 is attached to the floor board F, if the waste_water | drain hose of the washing machine which is not shown in figure is inserted in the one end part of the elbow member 5, and will fasten via the fixed band K (refer FIG. 1). Good. Thereby, the wastewater of the washing machine is guided from the elbow member 5 of the drainage discharge unit 1 to the bowl-shaped member 4 through the drainage hose. Then, the drainage led to the rod-shaped member 4 flows into one space having a semicircular cross section of the rod body 41 along the inclined portion 421 of the partition wall 42 and crosses the rod body 41 through the flow passage 4a. It reaches the other space having a semi-circular shape, overflows from the outlet 4b, and flows out to the drain pipe P.

That is, in FIG. 5, the rod-shaped member 4 includes a rod body 41, a plurality of hanging pieces 43 integrally connected to the upper end portion of the rod body 41 at intervals in the circumferential direction, and the hanging pieces 43. A ring-shaped support portion 44 integrally connected to the outer peripheral surface of the upper end portion, and this support portion 44 is supported by the inner flange 211 of the lower cylinder portion 21 in the connection member 2.

  On the other hand, a peripheral wall portion 53 that extends to the vicinity of the bottom surface of the body 41 of the rod-shaped member 4 is suspended from the inner peripheral portion on the other end side of the elbow member 5. Thereby, the flow path 4a can be formed between the lower end edge of the peripheral wall portion 53 of the elbow member 5 and the bottom surface of the body 41, and the drainage flowing down through the elbow member 5 is separated from the lower end edge of the peripheral wall portion 53. The water overflows from the upper end edge serving as the outlet of the rod body 41 through the flow passage 4 a between the bottom surface of the body 41 and flows out to the drain pipe P. At this time, the sealing water is secured by the height of the body 41.

  Furthermore, in the above-described embodiment, the case where the trapezoidal member 4 that secures the sealing water is provided in order to seal the odor rising up the drainage pipe P has been described. In the case where a drain trap for sealing with water is already provided, the corrugated member 4 is not necessarily provided.

In addition, an operation unit 111 for rotating the eye plate member 11 is provided, and is fitted into the elbow member 5 from the other end side.

  Next, the construction procedure of the drainage discharge unit 1A configured as described above will be described.

  First, an attachment opening Fa having a diameter larger than the outer diameter of the drain pipe P is formed in the floor board F in accordance with the installation position of the washing machine. Then, one end portion of the drain pipe P laid under the floor is raised so as to face the mounting opening Fa of the floor plate F. Next, an adhesive is applied to the outer peripheral surface of the upper end portion of the drain pipe P, and an adhesive is applied to the inner peripheral surface of the inner cylinder portion 71 of the connection member 7, so that the inner flange 711 of the connection member 7 is connected to the drain pipe P. The inner cylindrical portion 71 is inserted into one end portion of the drain pipe P until it abuts on the upper end of the tube, and the two are bonded together (see FIG. 10). When the bonding between the connecting member 7 and the drain pipe P is completed, the washing machine pan W is arranged on the floor board F with the drain port Wa aligned with the mounting opening Fa of the floor board F (see FIG. 11). At this time, a U-packing U is attached to the periphery of the drain port Wa in the washing machine pan W, and the U-packing U is placed on the outer flank 731 in the connecting member 7.

  Next, the flange member 8 is screwed to the connection member 7 through the drain port Wa of the washing machine pan W placed on the floor board F. That is, the external thread 83m of the outer cylinder part 83 of the flange member 8 is screwed into the female thread 73f of the outer cylinder part 73 of the connection member 7, and the flange part 82 of the flange member 8 and the outer flange 731 of the outer cylinder part 73 of the connection member 7 The U-packing U is sandwiched between and compressed to ensure the water tightness of the drainage port Wa of the washing machine pan W (see FIG. 12).

  When the screw connection of the flange member 8 to the connecting member 7 is completed, the foam trap member 9 is disposed inside and inserted into the outer peripheral side of the foam trap member 9, and the deodorizing cylinder member 10 is inserted via the outer flange 103. The rod-like member 4 supported by the support portion 44 is inserted into the drain pipe P through the flange member 8, and the support portion 44 is supported by the inner flange 811 of the inner cylinder portion 81 of the flange member 8. Further, the other end portion of the elbow member 5 to which the eye plate member 11 is attached is fitted into the fitting portion 91a of the cylindrical body 91 of the foam trap member 9 supported by the flange member 8, and the flange portion 52 is fitted. It supports to the upper end of the joining part 91a. Thereafter, if the eye plate member 11 is rotated using the operation portion 111 and the male screw 11 m is screwed into the female screw 81 f of the inner cylinder portion 81 of the flange member 8, the elbow member 5 is moved between the foam trap member 9. It can be fixed so as not to be pinched and detached.

  When the drainage discharge unit 1A is attached to the washing machine pan W in this way, a drainage hose of a washing machine (not shown) may be inserted into one end portion of the elbow member 5 and fastened via the fixing band K. Thereby, the waste water of the washing machine is guided from the elbow member 5 of the drainage discharge unit 1A through the drain hose to the trapezoidal member 4 through the foam trap member 9 and the flow passage 4a. The drainage led to the bowl-shaped member 4 gradually rises in water level, overflows from the upper edge thereof, and flows out to the drainage pipe P. At this time, inside the casing 41 of the bowl-shaped member 4, it is possible to secure the sealing water of the drainage having a height reaching the upper end edge serving as the outlet from the bottom surface, and the odor rising up the drain pipe P is sealed with water. can do. Further, the waste water that has flowed out into the washing machine pan W flows into the tapered portion 102 and the cylindrical body 101 of the deodorizing cylinder member 10 through the drain port Wa, passes through the folded portion 92 of the foam trap member 9, and the trapezoidal body 4. It flows to 41. At this time, the lower end edge of the deodorizing cylinder member 10 is disposed in the folded portion 92 of the foam trap member 9, so that the detergent bubbles contained in the drainage discharged from the washing machine raise the foam trap member 9. Further, it is possible to prevent the washing machine pan W from blowing up through the drain hole Wa of the eye plate member 11.

  By the way, when confirming the construction after the drainage discharge unit 1A is installed, the eye plate member 11 is loosened and the eye plate member 11 is detached from the flange member 8 together with the elbow member 5, and then the bowl-like member 4 is lifted up. The foam trap member 9 and the deodorizing cylinder member 10 supported by the shaped member 4 are taken out, and the flange member 8 is loosened and separated from the connection member 7, and the washing machine pan W is moved to connect the drain pipe P. This is done by exposing the connecting member 7 on the floor board F. Here, since the connection member 7 is colorless and transparent, the outer peripheral surface of the drain pipe P can be visually observed from above the floor board F through the inner cylinder part 71 of the transparent connection member 7. That is, the connection situation between the inner peripheral surface of the inner cylinder portion 71 and the outer peripheral surface of the drain pipe P in the connection member 7, specifically, the presence or absence of the adhesive and the application state of the adhesive are grasped from above the floor board F. Can do.

  Therefore, when the inner cylinder part 71 of the connection member 7 and the drain pipe P are fitted without using an adhesive, as described above, the inner peripheral surface of the inner cylinder part 71 in the connection member 7 and An adhesive agent can be apply | coated to the outer peripheral surface of the drain pipe P, respectively, and both can be adhere | attached. Thereby, the water leakage by the poor connection of the inner cylinder part 71 of the connection member 7 and the drain pipe P can be prevented reliably. Thus, if the connection confirmation of the connection member 7 and the drain pipe P is performed, although not shown in detail, the washing machine bread | pan W should just be fixed to the floor board F using a bis | screw etc. FIG.

  Also, the drainage discharge unit 1A can be mounted on the floor, and it is not necessary to provide an inspection port for entering the underfloor space, and it is not necessary to enter the narrow underfloor space through the inspection port. Together with the fact that it is not necessary to enter the space under the floor when confirming the construction, the entire work can be performed in a short time.

  In addition, since the connection member 7 should just confirm the connection condition with the drain pipe P, it may not only be colorless and transparent, but may be colored and transparent colored with yellow, red, blue, or translucent.

  Moreover, although the case where the outer peripheral surface of the drain pipe P is bonded to the inner peripheral surface of the inner cylinder portion 71 in the connection member 7 is illustrated, the outer periphery of the outer cylinder portion 73 in the connection member 7 depends on the pipe diameter of the drain pipe P The inner peripheral surface of the drain pipe P may be bonded to the surface. In this case, the inner peripheral surface of the drain pipe P can be visually observed from above the floor board F through the outer cylinder portion 73 of the transparent connecting member 7. That is, the connection situation between the outer peripheral surface of the outer cylinder part 71 and the inner peripheral surface of the drain pipe P in the connection member 7, specifically, the presence or absence of the adhesive and the application state of the adhesive are grasped from above the floor board F. Can do.

  Further, in the embodiment described above, the case where the trapezoidal member 4 that secures the sealing water is provided to seal the odor rising up the drain pipe P has been described. If the drain trap to be sealed is already provided, the corrugated member 4 is not necessarily provided. That is, as shown in FIG. 14, after fixing the connecting member 7 connected to the drain pipe P to the peripheral edge of the drain port Wa of the washing machine pan W through the flange member 8, the elbow member 5 to which the eye plate member 11 is attached. May be screwed into the flange member 8.

  As described above, according to the present invention, it can be easily attached to a floor board and the like, and since it can grasp the connection situation with the drain pipe by visual observation from the floor, it can be easily constructed and drained. Water leakage from the connecting portion with the pipe can be prevented, and work efficiency can be greatly improved in the field.
