Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a drainage structure around a fitting constituting an entrance in a bathroom having a unit structure in consideration of barrier-free, for example.
[0002]
[Prior art]
At the entrance of the unit bath (bathroom), the lower frame of the fittings and the bathroom floor should be flush with each other in order to prevent the disabled and the elderly in the wheelchair from tripping. This causes a problem that water easily leaks to the dressing room side beyond the room. In particular, when hot water overflows from the bathtub, a large amount of drainage becomes running water and flows vigorously through the washing place to the fittings side, and leaks to the undressing room side so as to seep out from the closed fittings.
In order to solve such a problem, there has been known a method in which a drainage groove closed with grating is provided on the bathroom floor adjacent to the lower frame (for example, Japanese Utility Model Laid-Open No. 1-118072). In this case, a large number of drainage holes are formed in the grating, and the drainage flowing toward the fittings flows down from the drainage hole to the drainage tank, and is guided from the drainage tank to the drainage pipe.

[Problems to be solved by the invention]
By the way, since the above-mentioned drainage system is treated in the bathroom (on the slab of the bathroom), the downstream end of the drainage pipe is connected to the drainage trap for the washing place drainage. For this reason, when hot water overflows in the bathtub, a large amount of wastewater concentrates on the wastewater trap, and there is a possibility that the wastewater may flow backward. In particular, in the case where the drainage leaking from the seal member of the fitting is guided to the drainage tank through the lower frame of the fitting, there is a possibility that the drainage leaks into the dressing room through the lower frame due to the backflow of the drainage.
[0004]
An object of the present invention is to provide a drainage structure for a bathroom that can slowly drain a large amount of drainage from a fitting side from a drainage storage tank over time.
[0005]
[Means for Solving the Problems]
In the bathroom drainage structure of the present invention, the drainage of the bathroom floor flowing to the entrance and exit of the bathroom is stopped by a seal member disposed on the bathroom side of a fitting constituting the entrance and exit, and the seal member is located near the bathroom side. In a bathroom drainage structure that is caused to flow downward through a drainage hole provided in a fitting and led to a drainage storage tank connected to a drainage pipe, a drainage hole is provided between the drainage storage tank and the drainage hole.

[0010]
In this case, it is preferable that the floor plate and the sub-drainage tank are integrally formed.
[0011]
According to this configuration, the floor plate and the sub-drainage tank can be easily created in a factory or the like, and can be easily and quickly constructed.
[0012]
In these cases, the drainage holes are formed in a lid-like plate detachably attached to the floor plate, and the lid-like plate preferably serves also as the upper lid of the sub-drain tank.
[0013]
According to this configuration, by opening the lid-shaped plate as the upper lid of the sub-drain tank, the inside of the sub-drain tank can be easily cleaned. In addition, by preparing a plurality of types of lid plates having different shapes and numbers of drain holes, it is possible to cope with the size of a bathroom (tub), interior design, and the like.
[0014]
Similarly, the drain hole is formed in a filter body detachably attached to an opening formed in the sub-drain tank, and it is preferable that the filter body also serves as a lower lid of the sub-drain tank.
[0015]
According to this configuration, the inside of the sub-drain tank can be easily cleaned by opening the filter body as the lower lid of the sub-drain tank. In addition, by preparing a plurality of types of filter bodies having different shapes and numbers of drain holes, the amount of drainage stored in the auxiliary drain tank can be adjusted. The filter body may be of a disposable type.
[0016]
Similarly, the sub-drain tank has a sub-drain tank main body and an opening / closing lid that opens the inside of the sub-drain tank main body, and the opening / closing lid is preferably detachably attached to the sub-drain tank main body. .
