BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage device for a bathroom which is disposed in a buried state on a bathroom floor surface and drains dirty water on the bathroom floor surface.

[0002]

2. Description of the Related Art FIG. 17 is an explanatory view showing a conventional bathroom drainer. This bathroom drainer comprises a stainless drainer body 61 having an upper opening and a bottom, and a synthetic resin trap 62 integrally attached to the lower portion of the drainer body 61. On the upper surface of the opening of the drainage body 61, a stainless lid plate 61a having a large number of drainage small holes formed in the surface is provided. When mounting on the bathroom floor surface, the drainage main body 61 with a trap is fitted into the drainage pilot hole (a pilot hole provided corresponding to the location where the sewage branch pipe 5 is installed) previously provided on the floor surface, and the trap 62 is attached. The connection port portion 63 is connected to the sewage branch pipe 5. In this state, the lid plate 61a is flush with the tile floor surface. Then, sand / cement (mortar or the like) is poured into the prepared hole to fix the drainage body 61. The floor surface sewage flows into the drainer main body 61 from the drainage small hole of the cover plate 61a and flows out to the sewer branch pipe 5 via the trap 62.

[0003]

In the construction of the floor drain of the bathroom, the water supplier normally connects the drain main body 61 to the sewage branch pipe 5 constructed at an appropriate place on the floor. After this, the domming house pours and fills the mortar (or sand / cement) into the prepared hole, and fixes the drainage body (with trap 62) 61. After the cement dries, the tiler tiles the floor. That is, the drain main body 61
Floor tiles around the top of the. In this way, the sewage branch pipe construction contractor, the drainer main body connection contractor, and the tile sticking contractor are each operated by different contractors. Therefore, at the stage of connecting the drainage body 61 to the sewage branch pipe 5, from the viewpoint of the position of the drainage body 61 with respect to the floor tile, that is, from the viewpoint of image alignment, the center of the drainage body (trap connection port portion) 61 and the sewage system. In many cases, the axial center of the branch pipe 5 does not match. In this case, conventionally, the drainer main body 61 and the sewage branch pipe 5 are connected via a bellows-shaped flexible connecting pipe 64 so that the drainer main body and the floor tile joint are aligned. However, the diameter of the drainer main body including the trap is gradually decreasing downward, and the drainer itself is extremely unstable, and the flexible connecting pipe 64 is affected by the load of the drainer main body 61 before the cement is hardened. It may sink downward or tilt. In this case, there is a disadvantage that it is necessary to redo even if the drainage main body and the floor tile are previously matched with each other and the height position of the floor is set.

The present invention solves the above-mentioned problems, enables simple and proper connection regardless of the installation position of the sewer branch pipe, and easily conforms to the center of the floor tile and the vertical and horizontal media of the floor tile. It is an object to provide a bathroom drainer that can be used.

[0005]

In order to achieve this object, the bathroom drainer according to the present invention has the following structure. The bathroom drainer includes a tube main body having a through hole in the center of the plane, and a rectangular receiving frame part which is fitted and arranged in the through hole of the tube main body and which is continuous with the upper peripheral part of the upper and lower opening tube part. , A rectangular drainage frame in which a tile storage tray part is fitted with a drainage gap around the rectangular receiving frame part, and a mounting cylinder part detachably attached to the lower part of the cylinder body and having a hole on the bottom surface, A projecting connection tube part provided between the mounting tube part and the bottom surface of the tube body and connected to the sewage branch pipe is composed of a movable body projecting outward from a hole of the mounting tube part. I am trying.

In the drainage device for a bathroom having such a structure, the sewage branch pipe installed in advance and the projecting connection tube portion of the movable body are directly connected. If the rectangular receiving frame (tile storage tray) of the media drain is aligned with the center of the floor tile attached to the floor around the sewer branch pipe installation and the media of the floor tile, it protrudes. In some cases, the center of the connecting tube and the center of the sewer branch pipe do not match. In this case, the cylinder body, that is, the rectangular receiving frame portion is held in a state of being matched with the center of the floor tile and the vertical and horizontal media (joint) of the floor tile,
The movable body is moved with fingers to align the center of the protruding connection cylinder with the center of the sewage branch pipe, and the protruding connection cylinder is fitted and connected to the sewage branch pipe. The upper peripheral surface of the outer peripheral wall of the movable body is in contact with the bottom surface of the cylinder body, and the bottom peripheral surface of the movable body is in contact with the inner bottom surface of the mounting cylinder portion. Further, the outer diameter of the movable body is set smaller than the diameter of the mounting cylinder portion (cylinder body). Therefore, within the area of the difference between the diameter of the movable body and the diameter of the mounting tube portion, the movable body, that is, the projecting connection portion is movable within a range of 360 degrees, and the projecting connection tube portion can be easily connected to the sewer branch pipe. obtain. Thus, since the projecting connecting tube portion of the movable body is directly connected to the sewage branch pipe, the flexible connecting pipe is unnecessary. In addition, all the loads are received in a stable state by the cylinder body with the largest diameter, and as a result, the cylinder body is firmly connected to the sewage branch pipe, so that the drainer drains before the cement poured into the pilot hole hardens. There is no fear that the whole will sink or tilt. In addition, after the tiles in the tile storage tray (square receiving frame) and the center of the tiles on the floor and the media are matched in advance, a simple work of holding this state and moving the movable body, The sewage branch pipe and the movable body can be connected.
