Description

  The present invention relates to a drainage socket of a flush toilet, and in particular, a drainage socket that joins a drainage channel from the flush toilet and a drainage channel of another device to communicate these drainage channels with a drainage pipe provided on the floor surface. About.

  In a toilet equipped with a flush toilet and a hand-washer, the waste water from the flush toilet and the waste water from the hand-washer are combined and discharged into one drain pipe. In this piping system, the drainage channel B1 from the flush toilet B and the drainage channel L1 from the hand-washer L as shown in FIGS. A drain socket 100 is used. This piping method is convenient because it is not necessary to newly start up a drainage pipe for a hand-washer, particularly when a hand-washer is added to an existing toilet.

  Japanese Patent Application Laid-Open No. 2003-27563 describes a toilet unit in which a flush toilet and a hand-washer are arranged via an L-shaped counter. In this toilet unit, the drainage line from the hand-washer passes through the L-shaped counter and is connected to the drain socket on the downstream side of the trap of the flush toilet. Are combined downstream of the flush toilet trap and discharged into the drainage pipe.

  However, because the configuration of the downstream pipe line of the flush toilet trap is related to the siphon action of the flush toilet, depending on the position and shape of the confluence outlet that joins the drainage from the flush toilet and the drainage from the handwasher There is a problem that the siphon action of the flush toilet may be weakened. This is because when negative pressure is generated in the pipeline due to the drainage from the flush toilet, the air is sucked into the pipeline from the merging outlet of the hand-washer drainage. This is because the formation of a necessary water film in the pipeline may be inhibited, or the duration of the siphon action may be inhibited.

  In addition, depending on the configuration of the pipeline at the junction, sewage discharged from the flush toilet may flow back to the drain of the handwasher drain through the junction outlet. There is a problem of clogging the road. Furthermore, when the drainage from the flush toilet flows in the pipeline and negative pressure is generated in the pipeline, the sealed water in the trap of drainage formed in the pipeline between the handwasher and the junction outlet is There is a problem that it may cause a blockage phenomenon that is sucked out and the sealed water is broken.

  Further, in FIG. 6, since the members constituting the drainage channel of the flush toilet are directly inserted into the drainage pipe disposed on the floor for connection sealing, the dimensions of the outlet of the flush toilet and the drainage pipe are shown. There is a problem that accuracy is required.

  Therefore, the object of the present invention is that the siphon action of the flush toilet is less likely to be weakened, and the filth discharged from the flush toilet is less likely to accumulate in the drainage channel where the drainage from the flush toilet is combined, and the flush toilet Another object of the present invention is to provide a drain socket that does not adversely affect the drainage path of other equipment joined to the drainage from the sewage and that does not require dimensional accuracy between the outlet of the flush toilet and the drainage pipe.

FIG. 1 is a view showing a state in which a drain pipe L1 of a hand-washing device L is connected to a drain socket 1 of a flush toilet B, (a) is a plan view, and (b) is a side view. FIG. 2 is a drain socket 1 shown in FIG. 1, wherein (a) is a plan view and (b) is a cross-sectional view.

  The drain socket 1 includes a first discharge path forming unit 10 and a second discharge path forming unit 5. The first discharge path forming part 10 includes an insertion port part 2a for inserting and storing the drainage port B2 of the flush toilet B, a linear first pipe line part 2b continuously provided below the insertion port part 2a, a first Consists of a vent-shaped second conduit portion 2c provided below the conduit portion 2b, a flange portion 11 formed on the outer peripheral edge of the insertion port portion 2a, and a projecting portion 11a projecting below the outer edge of the flange portion 11. is doing. The insertion port portion 2a and the first conduit portion 2b are integrally formed, and the first conduit portion 2b and the second conduit portion 2c are connected by an adhesive. Packing P1 is attached to the insertion port 2a to ensure watertightness and airtightness between the drainage port B2 of the flush toilet B and the insertion port 2a. The flange portion 11 and the projecting portion 11a block an open portion above the cylindrical portion 5a of the second drainage channel forming portion 5 described later.

  The second discharge path forming part 5 is disposed on the floor F, the connecting part L2 connecting the drain pipe L1 of the hand washing machine L provided on the upper side surface part of the cylindrical part 5a, the upper part of the cylindrical part 5. Consists of a communication part 5b for communicating with the drainage pipe D at the corner of the bottom part 6a of the cylindrical part 5a for communicating with the exhaust pipe D, legs 4 projecting forward on both sides and forward of the cylindrical part 5, They are integrally molded. And the bottom part 6a of the cylindrical part 5 is made into the inclined surface toward the inflow port 5c of the communication part 5b, in order to prevent accumulation of sewage. In addition, a hole 4a is provided at the tip of each leg portion 4 for passing a screw fixed to the floor surface.

  The first conduit portion 2b and the second conduit portion 2c of the first discharge passage forming portion 10 are inserted and accommodated from above into the cylindrical portion 5a of the second discharge passage forming portion 5, and the protruding portion 11a. The drainage socket 1 is formed by integrating the first discharge path forming part 10 and the second discharge path forming part 5 by fitting inside the upper end part 5d of the cylindrical part 5a and bonding and fixing them.

  A communication space 6 is formed between the tubular portion 5a, the first conduit portion 2b, and the second conduit portion 2c in a state where the first discharge passage forming portion 10 and the second discharge passage forming portion 5 are integrated. And the lower end part of the 2nd pipe line part 2c is a position close to the inflow port part 5c of the communication part 5b.

  Next, the operation of the drain socket 1 of the first embodiment will be described. First, when the wash water does not flow into the toilet bowl B3 of the flush toilet B, the water level in the toilet bowl B3 is maintained at the height of the highest point B4 of the sealed trap of the flush toilet B. When the washing water flows into the toilet bowl B3, the washing water flows into the drain socket 1 beyond the highest point B4 of the trap. The washing water that has flowed into the drain socket 1 flows down the first pipe line portion 2b and jumps up by hitting a bent portion of the lower second pipe line portion 2c. The washing water that has jumped up forms a water film near the lower end of the second pipe portion 2c, causing a siphon action, and the washing water and filth in the toilet bowl B3 are sucked. In the drain socket 1 of the present embodiment, negative pressure is generated in the second conduit 2c and the drain B1 of the flush toilet B by the attractive force acting on the wash water filled in the second conduit 2c, and the toilet bowl B3 The siphon action that sucks the cleaning water and dirt inside is used.

  Drainage from the drain pipe L1 of the hand-washing machine L is a gap between the connection port L2 and the communication space 6, the end of the second pipe part 2c of the first discharge path forming part 10 and the bottom part 6a of the cylindrical part 5a. Flows into the communication part 5b and is discharged to the drain pipe D.

  From the above, by providing the hand-washing drainage connection port L2 at an independent position away from the second pipe portion 2c of the drainage socket 1, the influence on the siphon action of the flush toilet B is very small. In addition, the wash water that has passed through the second pipe part 2c passes through the communication part 5b and is discharged to the drain pipe D, and the siphon action of the flush toilet B is negative pressure broken at the lower end of the second pipe part 2c. Therefore, there is almost no negative pressure on the drain pipe L1 of the hand-washer L. Therefore, it is possible to prevent the sealing water (not shown) of the trap provided with the drainage path of the hand-washing device L from being sucked out and causing the breakage.

  Further, even when the siphon is generated, air on the hand-washer side does not flow into the drainage channel B1 and the second conduit portion 2c of the flush toilet B, and stable siphoning force can be maintained. Furthermore, since the wash water drained from the second pipe portion 2c flows directly into the drain pipe D, the sewage does not flow back into the hand-wash drain pipe L1, and the sewage does not accumulate.
