When water flows into the opening/closing hole 161b, the opening/closing plate 167 is pressed by the load of the water so that the opening/closing plate 167 is opened to allow drainage, and when the inflow of water into the opening/closing hole 161b is stopped, The load factor applied to 167 is removed, and the weight 168 is rotated downward by its own weight, and accordingly, the opening and closing plate 167 is rotated upward, so that the opening and closing plate 167 can block the opening and closing hole 161b. At this time, the opening/closing plate 167 is attached to the opening/closing hole 161b by magnetic force to more reliably block odor rising from the drain.

When the opening/closing plate 167 is configured to be attached to the opening/closing hole 161b by magnetic force, the water drained while the opening/closing hole 161b is blocked by the opening/closing plate 167 is discharged from the lower part of the shutter body 161. A predetermined amount of water is filled in, and the load of the stored water separates the opening/closing plate 167 from the opening/closing hole 161b so that drainage can be made. It is preferable that the water level filled in the lower part of the shutter body 161 is lower than the upper part of the inclined drainage guide surfaces 162 and 163 so that the plate 167 is separated from the opening and closing hole 161b.

That is, in the present invention, when the water is filled in the lower part of the shutter body 161 in a state where the opening and closing plate 167 is attached to the opening and closing hole 161b by magnetic force, the water fills up to the top of the inclined drainage guide surfaces 162 and 163. Separation of the opening/closing plate 167 from the opening/closing hole 161b by the load of the water before being filled can ensure smooth drainage of water as well as odor blocking performance.

In the above, the present invention has been shown and described in relation to preferred embodiments for illustrating the principles of the present invention, but the present invention is not limited to the configuration and operation as shown and described. Rather, those skilled in the art will appreciate that many changes and modifications to the present invention can be made without departing from the spirit and scope of the appended claims. Accordingly, all such appropriate changes and modifications and equivalents should be regarded as belonging to the scope of the present invention.
