[Industrial applications]

 The present invention relates to a water collecting and draining device for preventing water from leaking downstairs in combination with a drainage basin with a trap buried in a drainage floor such as a bathroom washing place.

[0002]

[Prior art]

 For example, in a bathroom washroom, a large amount of drainage is discharged at one time when washing the body. For this reason, if the drainage is not performed promptly, the drainage will be stagnant in the drainage part, and the dirt and hair inside the drainage part will be raised, and the washing area will be unclean. Therefore, as the drainage structure to be installed in the washroom, drainage basins with good drainage efficiency are currently the mainstream. This drainage basin has a basin with sufficient capacity to accommodate drainage, a trap device is attached to the drainage part at the bottom of the basin, a lid is attached to the upper opening, and it is buried in the washing floor. It is a thing. According to this, even if there is a large amount of drainage, the drainage is once stored inside the cell, so that it does not overflow into the washing area and does not become filthy. In addition, since the drainage basin has a large area where water is introduced, it is easy to incline the floor tile during construction, and there is an advantage that a wide floor tile can be used. On the other hand, however, since this drainage basin has a long bond with the base mortar and joints, there is a high possibility that water will leak due to cracks in the bond or peeling from the boundary. If water leaks, there will be no problem if the construction site is on the first floor, but if it is constructed in a bathroom above the second floor, the leak will bleed downstairs and will eventually drain. In order to solve this problem and to make it possible to construct a drainage basin in the bathroom above the second floor, the present inventor has described in Japanese Utility Model Laid-Open No. Sho 62-89390, "A drainage drainage device used for a drainage basin with a trap. Is proposed.

[Problems to be solved by the device]

 The "collection and drainage device used for drainage basin with trap" described in the above publication blocks water leaks from the base mortar and the joints with joints, collects this in the collection and drainage device, and guides it to the drain pipe, downstairs. It has a sufficient function in terms of preventing water leakage. However, since the communication hole in the water collection and drainage device that connects the water collection flange and the inside of the water collection and drainage device does not have an airtight separation means such as a trap device, the reverse flow of dirty odor is slight. I found out that

[0004]

[Means for Solving the Problems]

 The configuration of the present invention taken to solve the above problems is as follows. That is, the present proposal is a water collecting and draining device for use with a drainage basin with a trap that is buried in the drainage floor of a bathroom washing room, etc., and the water collecting and draining device has a bowl-shaped main body, and an upper part of the main body. Is provided with an insertion cylinder portion into which the drain trap of the drainage basin with a trap is inserted, and a water collecting flange for collecting leakage water is provided on the outer peripheral portion of the insertion cylinder portion. The side wall is provided with a required number of communication holes that lead from the water collecting flange to the inside of the water collection and drainage device, and the inside of the water collection and drainage device of the communication hole is a track for airtightly separating the inside and outside of the water collection and drainage device. It is a water collecting and draining device used for drainage basins with traps that have attached pipes. The shape of the water collecting flange of the water collecting and draining device is, for example, a disk shape with an inclined surface formed at the peripheral portion, but the shape is not particularly limited as long as it has a function of collecting water leakage. The material of the trap tube is, for example, synthetic resin such as vinyl, or metal, but is not limited thereto. The shape is not particularly limited, and is, for example, U-shaped, S-shaped, or α (alpha) -shaped, and the water remaining inside after water is passed through the air-tight separation device allows water to pass through inside and outside the water collection and drainage device. Any material that can prevent the backflow of dirty odor may be used. Further, the method of attachment to the communication hole is not limited, and known means such as adhesion, press-fitting, and screwing may be used.

 The present invention will be described in more detail based on the embodiments shown in the drawings. FIG. 1 is an exploded perspective view of a drainage basin and a water collection and drainage device, and FIG. 2 is an explanatory view showing a state in which a communication hole and a trap tube are attached. Reference numeral 1 denotes a water collecting and draining device, which has a substantially bowl-shaped main body 10. On the upper part of the main body 10, there is formed an insertion cylinder portion 12 into which a trap base 230 of a drainage basin 2 to be described later is inserted. Two annular packings 15 are attached to the inner wall 13 of the insertion tube portion 12, and the trap base 230 is fitted in the packing 15 and inserted in a watertight state. The insertion depth of the trap base 230 can be adjusted within a certain range, and the drainage basin 2 can be flexibly installed even on bathroom washing floors of various heights. A disc-shaped water collecting flange 16 is provided on the outer peripheral portion slightly below the upper edge of the insertion tube portion 12. The peripheral edge of the water collecting flange 16 is inclined upward to facilitate the collection of water leaks. The side wall of the insertion tube portion 12 is formed with four communication holes 17 which are substantially flush with the upper surface of the water collecting flange 16 and penetrate the insertion tube portion 12 and communicate with the inside of the main body 10. A trap pipe 18 made of a vinyl pipe is fitted into each communication hole 17 by being press-fitted from the inside of the main body 10. The trap tube 18 is formed in a U shape, and water remains inside even after passing water, and the inside and outside of the main body 10 can be airtightly separated. At the bottom of the main body 10, a cylindrical drain portion 19 is formed so as to protrude downward. An attachment screw portion 190 for attaching the drainage pipe 40 is provided on the inner wall of the lower portion of the drainage portion 19. (Operation) FIG. 3 is a sectional view showing a construction state of an embodiment of the present invention. The operation of this embodiment will be described with reference to FIGS. The water collection and drainage device 1 is embedded in the slab concrete C. The water-blocking sheet 3 is laid on the upper surface of the slab concrete C. A water guide port 30 is provided at a predetermined position of the water shield sheet 3. The slab concrete C at the edge of the water inlet 30 is formed to be slightly recessed, and the water blocking sheet 3 is laid along it. The water collecting and draining device 1 is arranged below the water guiding port 30 of the water blocking sheet 3, and the edge of the water guiding port 30 is placed on the water collecting flange 16 of the water collecting and draining device 1. A drain pipe 40 is connected to the drain portion 19 of the water collecting flange 16. On the water-blocking sheet 3, the base mortar M is driven. The drainage basin 2 is embedded in the base mortar M. A floor tile T is stretched over the base mortar M.

The drainage trap device 23 includes a trap base 230, and a water-sealed trap is formed inside the trap base 230. A separation net 231 is placed above the drain trap device 23. According to this structure, when water is leaked due to cracking or separation at the boundary between the drainage basin 2 and the base mortar M, the water leakage is first blocked by the water blocking sheet 3 and then by the water collecting flange 16. Collected. Since the collected leaked water is introduced into the inside of the main body 10 through the communication hole 17 and the trap pipe 18, the leaked water does not seep or flow downstairs. Further, since the trap tube 18 is formed in a U shape, water remains inside after passing water, and the inside and outside of the main body 10 are airtightly separated. As a result, the dirty odor from the inside of the main body 10 of the water collection and drainage device 1 and the drain pipe 40 and the like following it stops inside the main body 10 and does not flow back into the bathroom. In addition, it is desirable to pass water through the trap tube 18 at the time of construction so that the trap tube 18 can perform the function of blocking dirty odor even if water leakage does not occur. Further, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the claims for utility model registration.
