In addition, in order to allow the drainage accumulated on the bathtub waterproof pan 3 to flow into the drain trap 8, the bathtub waterproof pan 3 is provided with a bathtub waterproof pan drain port 3b with a check valve. The drainage on the bathtub waterproofing pan 3 can be caused to flow into the drainage trap 8 from 3b through the drainage pipe 7.
In addition, the discharge pipe 13 is connected to the outflow port 8e of the drain trap 8, and the discharge pipe 13 is connected to the sewer pipe.

The drain trap 8 has a structure shown in a perspective view in FIG. 2 and a planar configuration cut horizontally in FIG.
On the top surface 8a side of the drainage trap 8, a washing ground drainage inlet 9 into which drainage from the washing place flows is opened, and in this washing ground drainage inlet 9, a hair catcher 10 for removing hair and the like is provided. It is installed.
The inside of the drain trap 8 is partitioned into an inflow chamber R1 and an outflow chamber R2 by a planar curved shielding member 8b extending from the top surface 8a. The inner peripheral surface 8c of the inflow chamber R1 is separated from the shielding member 8b. It is formed in a continuous curved surface, and a bathtub drainage inlet 11 is opened in a vertically long shape on the inner peripheral surface 8c, and a connecting portion 11a that continuously protrudes outward is formed in the bathtub drainage inlet 11. A drainage hose 6 connecting the bathtub drainage port 4a is connected to the connection part 11a.

Further, a bathtub waterproof pan drainage inlet 12 is opened in the downstream area of the bathtub drainage inlet 11 on the inner peripheral surface 8c of the inflow chamber R1, and the bathtub waterproof pan drainage inlet 12 projects outward. A connecting portion 12a is formed, and a drain pipe 7 that connects the bathtub waterproof pan drain port 3b of the bathtub waterproof pan is connected to the connecting portion 12a.
A sealing wall 8d is formed on the outlet side of the outflow chamber R2 in the drain trap 8, and an outlet 8e is formed on the downstream side thereof.

In this example, a cap 15 is fitted and attached to the bathtub waterproof pan drainage inlet 12.

A lower passage is formed on the lower side of 15e, and an outflow lateral hole 152 is formed by opening in the lateral direction on the hanging piece 15d side of the lower passage.
That is, in a state where the cap 15 is inserted and attached to the bathtub waterproof pan drain inlet 12 of the drain trap 8 from the inside, the curved surface 15b becomes a continuous curved surface flush with the inner peripheral surface 8c of the drain trap. The inflow vertical hole 151 is opened toward the bathtub drainage inlet 11 side, and the outflow horizontal hole 152 is opened in the opposite direction downward on the opposite side.
In addition, in FIG. 9, the longitudinal cross-section expanded block diagram of the state which fitted the cap 15 in the bathtub waterproofing pan drainage inflow port 12 is shown.

Next, the function and effect of the drain trap 8 configured as described above will be described.
When the bathtub drain port 4a on the bottom of the bathtub is opened, the bathtub water in the bathtub 4 passes through the drain hose 6 and flows into the inflow chamber R1 from the bathtub drain inlet 11 of the drain trap 8, and from the bathtub drain inlet 11 The bathtub drainage that has flowed into the inflow chamber R1 vigorously swirls along the curved surface of the inner peripheral surface 8c and the shielding member 8b, and a vortex is generated inside.
Since the inflow vertical hole 151 of the cap 15 attached to the bathtub waterproofing pan drainage inlet 12 is open with respect to the direction of the vortex, the vortex is easy to flow in. In addition, since it is opened in the vertical direction, The vortex is pushed into the cap insertion cylinder 15a from the cap inflow longitudinal hole 151, and the vortex is pushed further into the drain pipe 7 from the connection portion 12a through the upper side of the partition piece 15e.
Since the vortex pushed into the drain pipe 7 has momentum, it reaches the vicinity of the bathtub waterproof pan drain outlet 3b. Since the bathtub waterproof pan drain outlet 3b is provided with a check valve, the vortex is waterproof in the bathtub. It does not flow into the pan 3.

The vortex flow pushed to the vicinity of the bathtub waterproof pan drain outlet 3b is returned to the bathtub waterproof pan drain inlet 12 by gravity through the bottom side of the drain pipe 7, and the drainage returned is divided into pieces. The drainage trap 8 is returned from the outflow lateral hole 152 through the lower side of 15e.
In addition, since this outflow horizontal hole 152 is opened on the opposite side to the inflow vertical hole 151 in the flow direction of the vortex flow, the drainage from the outflow horizontal hole 152 satisfactorily rides on the vortex flow in the inflow chamber R1. It is returned to R1. The vortex is blocked by the hanging piece 15d and is prevented from flowing into the outflow lateral hole 152.

  Therefore, the vortex generated in the inflow chamber R1 is pushed into the drain pipe 7 from the inflow vertical hole 151 of the cap and satisfactorily replaced with the water accumulated in the drain pipe 7, and the vortex flows from the outflow lateral hole 152. The water flows into the inflow chamber R1 every time a vortex is generated in the drain pipe 7 and the water accumulated inside the drain pipe 7 is replaced. It will be well prevented that wastewater accumulates and the wastewater rots and emits a foul odor or becomes unsanitary, thus eliminating the occurrence of dead water in the drainage pipe 7 well. Will be able to.
