Description

[Detailed Description of the Invention] The present invention relates to a drainage device formed on the floor of a toilet, washroom, or the like.

Generally, a toilet or washroom is provided with a drainage device M1 as shown in FIG. is provided with a metal filter 2, and the upper end of a drain pipe 3 is open at the bottom of the drain hole 1.

The upper end of the drain pipe 3 projects slightly above the bottom surface 1a of the drainage receiving hole 1, and a bell-shaped lid 4 made of a metal material is provided to cover this projecting portion.

As shown in FIG. 2, the lid 4 has an opening edge 4a.
A plurality of notches 4b are formed in the drain hole 1, and the drain water flows from the drain hole 1 into the drain pipe through the cutouts 4b.

Since the lid 4 is provided to prevent odor from leaking from the drain pipe 3, the height of the notch 4b must be lower than the protrusion length 1 of the drain pipe into the drain hole 1. ,
By keeping the notch 4b submerged in water, odor leakage is prevented.

Therefore, since the notch 4b cannot be made very large, the notch becomes clogged with dirt and dust, and the lid body 4 often has to be removed from the drain hole for cleaning.

In view of this, an object of the present invention is to provide a drainage device that can prevent clogging with dirt and dust, and can also prevent odor leakage.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 3 and 4, the upper surface of a drainage hole 1 formed in the floor surface f is closed with a filter, and the upper end of a drain pipe 3 is opened at the bottom surface of the drainage hole 1 so as to protrude slightly.

Drainage always accumulates from the bottom of the drainage receiving hole 1 to the upper end 3 of the drainpipe, and a bell-shaped lid 5 floats above the drainage.

The lid 5 is made of a light material such as plastic, and a ring-shaped hollow float 6 is attached to the mouth edge of the lid 5.

This lid body 5 does not need to be provided with a notch as a drainage passage as in the conventional case, so the cause of clogging with dirt is eliminated.

The lid body 5 moves up and down depending on the amount of wastewater stored in the drain hole 1, but since the drain surface and the float 6 are always in contact, the odor from the drain pipe 3 will be released depending on the amount of wastewater stored. No matter what happens, it will not leak to the outside.

As explained above, the present invention creates a recess in the floor surface to form a drainage hole, and opens the tip of the drain pipe at the bottom of the drainage hole to prevent odor from leaking onto the drain pipe. In this drainage device, the lid is made of a bell-shaped light material, and a ring-shaped float is attached along the edge of the lid to prevent dirt and dust from entering the drainage hole. This has the effect of not clogging the room and completely preventing odor leakage.
