DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain gutter lid attached to a drain gutter provided on a waterproof pan.

[0002]

2. Description of the Related Art Conventionally, a waterproof pan has a downward slope toward a drain, so that dirty water such as washing water collects in the drain. In addition, a drain groove lid having a through hole is provided in the drain groove to facilitate walking and improve design. Therefore, washing water or the like collected toward the drainage ditch is guided to the drainage ditch through a through hole provided in the lid for the drainage ditch.

[0003] Such drainage lids are described, for example, in Japanese Utility Model Laid-Open Publication No. 6-30267, in a continuous drainage groove provided on at least three sides including the entrance and exit sides of the outer peripheral edge of a waterproof pan of a bathroom unit. A ditch lid to be placed is described. The waterproof pan is inclined downward toward the drain, and the washing water and the like are collected in the drain through the through hole of the lid for the drain, and drained from the drain provided in the drain. . By doing so, the washing water and the like are efficiently guided to the drain, and can be drained reliably. However, there is a disadvantage that a long drain groove cover is required, and it takes a long time to clean the drain groove cover.

[0004] As a cover for a drainage ditch aiming at solving the above-mentioned drawbacks, for example, Japanese Unexamined Patent Publication No. 8-277558 discloses a drainage ditch provided on one side of a waterproof pan of a bathroom unit. Is described. The waterproof pan has an upward slope toward the entrance, and the washing water and the like flow to the opposite side of the entrance, and are drained from a drain provided there. A drain hole is provided in the drain cover provided on the entrance side, and washing water and the like flowing backward in the gradient are guided to the drain through the through hole, and from the drain provided in the drain. It is designed to be drained. Since the drainage groove is provided only on one side of the waterproof pan, the lid for the drainage groove can be short. That is, cleaning of the drainage cover can be completed in a shorter time than providing drainage grooves on a plurality of sides of the waterproof pan.

[0005]

However, even in the case of the drainage cover described in Japanese Patent Application Laid-Open No. 8-277558, the cover is provided with a through hole so that dirty water such as washing water can be used. Is guided to the drainage channel through the through hole, so that not only the surface of the lid but also the inside of the through hole is contaminated. For this reason, cleaning the inside of the through hole requires a lot of trouble even if it is a short cover for the drain ditch. Also,
Since it was difficult to completely clean the inside of the through hole, it caused odor in the bathroom. Also, the drainage lid on the entrance side is often stepped on with bare feet, but has a poor walking sensation because of the through holes. Furthermore, the lid for the drainage groove having the through hole cannot be designed to be the same as the surface of the waterproof pan, and there has been a limit on the design.
