Description

  The present invention relates to a drainage structure for a bathroom.

Conventionally, as disclosed in Patent Document 1, there is a drainage structure for a bathroom that is configured to allow drainage from a bathtub to flow from above into a drainage port formed on the side of a washing place through a drainage channel under the bathtub. .
JP-A-7-102605

  In the conventional bathroom drainage structure, since the bathtub drainage is simply poured into the drainage outlet formed in the washing area from above, the hair that sticks around the drainage outlet cannot be washed out well, and the drainage outlet There was a problem when the dirt stuck.

  The present invention has been devised in view of the above-described conventional problems, and uses a flow rate and a flow rate of drainage from a bathtub to provide a bathroom drainage structure that can wash away hair that has been well-attached. The first aspect of the present invention provides a bathtub drain pipe which is provided with a water outlet on the elevation surface of a drainage basin formed in a concave shape on the bathroom floor surface, and can discharge bathtub drainage into the drainage basin at the water outlet. Is connected.

  Further, the second aspect of the present invention is that the bathtub drain pipe is branched from a bathtub main drain path that connects a drain outlet of the bathtub and a trap under the drainage tub.

  The third aspect of the present invention is that the discharge direction of the bathtub drain pipe does not face the center of the inlet of the bottom surface of the drain.

  The drainage structure of the bathroom of the present invention is provided by providing a water discharge port on the vertical surface of the drainage basin formed in a concave shape on the bathroom floor, and connecting a bathtub drainage pipe that can discharge the bathtub drainage into the drainage basin at the water discharge port. From the vertical surface of the drainage tub, the bathtub drainage can be poured into the drainage basin. Can be washed away well.

  In addition, the bathtub drain pipe is branched from the bathtub main drainage path that connects the drain outlet of the bathtub and the trap at the bottom of the drainage bowl, so that a part of the bathtub drainage drained from the bathtub can be satisfactorily placed in the drainage bowl. The hair that has been discharged and stuck into the drainage can be washed away well, and most of the bathtub drainage can be washed away from the bathtub main drainage path to the trap.

  In addition, because the discharge direction of the bathtub drain pipe does not face the center of the inlet of the drainage basin, the bathtub drainage flows into the drainage basin from the vertical surface of the drainage basin, and the drainage basin is vigorously driven by fluid energy. The tub drainage is spread over the entire interior, so that it is possible to wash away loose hair.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a vertical cross-sectional configuration diagram of a main part of a bathroom, and a drainage basin 3 is formed in a concave shape on the bathtub 7 side of the wash basin pan 2, and this drainage basin 3 has an inlet 4 at the center. A rising surface 3b rising upward from the outer periphery of the bottom surface 3a is formed, and the top plate 10 is covered on the top surface.
In addition, a drain trap 5 having a deodorizing cylinder 5b is provided in the lower part of the inflow port 4, and a drain pipe connecting portion 5a for connecting a drain pipe (not shown) is formed on the side surface of the drain trap 5. Has been.
An apron 6 is erected on the left end of the drainage basin 3 in the figure, and the side surface of the bathtub 7 is covered with the apron 6.

  A drainage port 7 a is formed on the bottom surface of the bathtub 7, and a bathtub main drainage path 8 for draining bathtub water from the drainage port 7 a is connected to the side surface of the trap 5. Further, a bathtub branch drain pipe 9 is provided so as to branch upward from the bathtub main drain path 8 and an upper end of the bathtub branch drain pipe 9 is orthogonal to the vertical surface 3b of the drainage basin from the back side. A water outlet 9 a is opened inside the elevation surface 3 b of the bathtub branch drain pipe 9.

As shown in the enlarged perspective view of the drainage basin in FIG. 2, the water discharge port 9 a flows in the discharge direction of the water discharge port 9 a so that the tub drainage flows into the inflow port 4 of the bottom surface 3 a of the drainage basin 3. It is not facing the center of the entrance 4.
In such a configuration, the drainage port 7a of the bathtub 7 is opened, and the bathtub drainage in the bathtub flows into the trap 5 through the bathtub main drainage path 8, and drains from the drainage pipe connection 5a to the drainage pipe (not shown). However, a part of the bathtub drainage passes through the bathtub branch drain pipe 9 and is discharged into the drainage basin 3 from the spout 9a.

  The bathtub drainage discharged from the spout 9a has a large flow rate and flow velocity, and flushes the rising surface 3b of the drainage basin 3 with fluid energy, and further flows into the entire bottom surface 3a so as to draw a vortex. In addition, dirt and hair attached to the bottom surface 3a can be swept away by a vortex, and dust and hair can be collected well on a hair catcher attached to the inlet 4 and then flowed. The bathtub drainage is discharged from the inlet 4 through the drainage trap 5.

Thus, dirt and hair clinging to the vertical surface 3b and the bottom surface 3a of the drainage basin 3 are well collected by the hair catcher of the inflow port 4, and the hair catcher is removed from the inflow port 4. By cleaning the hair catcher, hair and the like can be removed well.
As described above, the fluid energy of the bathtub drainage can be used to drain the water in the drainage basin 3 over a wide range while washing away the hair that has been stuck.

It is a principal part expansion longitudinal cross-section block diagram of a bathroom. It is an expansion perspective view of the drainage basin of FIG.
