Further, the engaging member 30 connects the mounting portion 7 and the flange portion 12 of the drainage device 11 through the flange portion 4 and the packing 17 of the tank body 1 by the engagement of the claw portion 31.

  The tank body 1 and the drainage device 11 described above are attached as follows.

First, in the factory, as shown in FIGS. 31 to 34, the attachment portion 7 is inserted through the drain outlet side wall 3 in a state before the flange portion 4 is formed. In addition, before the collar part 4 formation, the notch 5 is provided in the drain outlet side wall 3 from the middle to the lower end.
After the attachment portion 7 is inserted through the drainage side wall 3, the drainage side wall 3 is bent outward as shown in FIGS. At this time, the drain outlet side wall 3 has a substantially quadrangular shape in plan view, and the corner (the rounded portion) of the drain outlet side wall 3 has a notch 5, so that the drain outlet side wall 3 can be easily bent outward. I can do it. Further, the flange portion 4 is formed by the bending, so that the attachment portion 7 is positioned and fixed to the outer periphery of the drain outlet side wall 3.
Next, as shown in FIGS. 37 and 40, the flange portion 12 of the drainage device 11 is brought into contact with the gasket 17 from below the flange portion 4 via the packing 17. Then, as shown in FIGS. 41 and 42, the claw portion 31 is rotated in a state where the engaging member 30 is in contact with the lower portion of the flange portion 12 to engage the concave portion of the mounting portion 7 with the claw portion 31. Thus, the attachment portion 7 and the flange portion 12 of the drainage device 11 are connected by the engaging member 30. At this time, since the engaging member 30 connects the attachment portion 7 and the flange portion 12 of the drainage device 11 via the flange portion 4 and the packing 17, the flange portion 12 is connected to the attachment portion 7 in a watertight manner.
Further, as shown in FIGS. 43 and 44, a lid member 23 and a strainer 24 are installed in the drain outlet 2 or the drainage device 11.
Here, the drainage pipe 15 is inserted into the discharge port 13 of the drainage device 11 and connected in a watertight manner using a cap nut, packing, or the like.
As shown in FIG. 29, the drainage pipe 15 extends horizontally along the back side of the bottom surface of the tank body 1 and then is connected to the underfloor pipe via a drainage trap S that is an S-shaped drainage trap. In addition, the success of the drainage pipe including the attachment of the drainage device 11 is completed.

  That is, in the third embodiment, since the connection between the tank body 1 and the drainage device 11 is completed simply by rotating the claw portion 31 with the engaging member 30 in contact with the flange portion 12, the construction is easy. is there.

  Similarly to the second embodiment, since the attachment portion 7 fills the gap 6 generated when the flange portion 4 is bent from above, water tightness can be improved.

In forming the flange 4, the lower end (bottom) of the flange 4 protrudes from the drain side wall 3 by the thickness of the flange 4, but the thickness of the stainless steel itself is as thin as several millimeters. There is no problem with watertightness by contact.
On the other hand, when forming the flange portion 4, a cut is made between the drain outlet side wall 3 and the flange portion 4 so that the drain outlet side wall 3 and the lower end of the flange portion 4 are flush with each other after the folding, or the packing 17 or the mounting portion. The shape of 7 may be changed, or an appropriate design change may be added.

The embodiment of the present invention is as described above, but the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist of the invention. For example, in the first to third embodiments, the drain port 2 and the drain side wall 3 have a substantially square shape in plan view, but may have a substantially regular hexagonal shape or other polygonal shape. Also good.
Further, the shape is not necessarily a polygonal shape, and may be other shapes such as an elliptical shape.

  That is, the outer periphery of the drain outlet side wall 3 and the inner periphery of the mounting portion 7 attached to the outer periphery of the drain outlet side wall 3 may be in any shape that does not rotate in the circumferential direction. It refers to a shape that does not rotate in the circumferential direction.
