[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a bathroom drainage unit, and more particularly to a bathroom drainage unit formed to prevent drainage from a bathtub or a washing pan from flowing back to a bathtub pan for placing the bathtub.
[0002]
[Prior art]
By the way, since a large amount of drainage from a bathtub or a washing pan flows at a time, it may flow backward and wet the bathtub pan. If the bath tub gets wet and becomes contaminated with drainage, it becomes unsanitary and the bath tub becomes a source of off-flavors. However, the bathtub pan is not visible from the bathroom and cannot be easily cleaned by reaching.
[0003]
Therefore, in order to solve this kind of problem, conventionally, a float plate is provided at the drain port of the bathtub pan so as to be vertically movable, and the float plate is pressed against the perforated plate by buoyancy at the time of drainage to close the opening of the perforated plate. There is one formed to prevent backflow (for example, see Japanese Patent Application Laid-Open No. 9-195348).
Also, a drain tube having a narrowed lower end attached to a drain port of a bathtub pan is formed so as to prevent backflow into the bathtub pan by using the drain tube (see, for example, JP-A-2000-29097). ).
[0004]
[Problems to be solved by the invention]
However, in the conventional example, the drainage from the bathtub and the bathtub pan is usually made to flow to the drainage trap on the washing place side by the same drainage pipe. Therefore, according to the conventional example, when a large amount of hot water is drained from a bathtub or a washing pan at a time, it is easy to flow backward through a drain pipe. Further, even if a float plate is provided at the drain port of the bathtub pan, if the amount of drainage from the bathtub or the washing pan is large, the backflow cannot be sufficiently prevented, and the bathtub pan may be soiled. Further, in the case of the conventional example in which a drain tube with a narrowed lower end is provided at the drain port of the bathtub pan, there is a fear that the flow of drainage from the bathtub pan is obstructed. This is because the drainage from the bathtub pan is when water enters the bathtub pan, and the amount of drainage is originally small, so it is usually difficult to obtain the pressure necessary to spread the tube. .
[0005]
The present invention has been proposed in view of such a conventional situation.
Therefore, a technical problem of the present invention is to provide a bathroom drain unit formed to prevent drainage from a bathtub or a washing pan from flowing back to the bathtub pan and to keep the bathtub pan constantly dry without getting wet. is there.
