Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor pan for a bathroom which is installed on the floor of a bathroom to make the bathroom waterproof and to install a bathtub or a washing room on the upper side.

[0002]

2. Description of the Related Art A bathroom floor pan that forms a bathroom has a drainage port, and the drainage generated on it is discharged from the drainage port. Since the appearance is impaired when exposed on the upper surface, the drainage port is provided at a position where it cannot be seen from the outside. As an example of such a floor pan for a bathroom, a drain part formed in the shape of a box with a bottom is provided below the floor pan body, and the upper surface of the drain part is opened at the bottom surface of the floor pan body, and There is a system in which a drain port is provided on the bottom surface and a lid with a drain hole is provided at the top opening of the drain part.In this type, the drain port can be seen from directly above by covering the top opening of the drain part with a lid. You can avoid it.

Recently, in order to efficiently discharge the drainage, it has been proposed to form a drainage groove in the floor pan for the bathroom and connect the end of the drainage groove with the upper surface opening of the drainage part. In this bathroom floor pan, drainage is efficiently discharged by pouring it into the drainage section through the drainage channel.

[0004]

However, in the bathroom floor pan provided with the drainage groove as described above, since the drainage portion and the end portion of the drainage groove are communicated with each other, the drainage portion is provided obliquely above the lid. There is a problem in that the drainage port inside the drainage section can be seen through the gap at the boundary of the drainage channel, which impairs the appearance.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a floor pan for a bathroom, which does not impair the appearance.

[0006]

In a bathroom floor pan according to the present invention, a drainage groove 2 is provided on the bottom of a floor pan body 1 and a drainage section 3 provided with a drainage port 7 is located below the drainage groove 2. The drain pan 3 is opened to the bottom surface of the floor pan body 1 and the drain opening 3 is connected to the drain groove 2. Drainage 2
Cover piece 6 projecting so as to cover the boundary with the drainage part 3 of the
It is characterized by being formed by extending.

[0007]

The drainage groove 2 is formed on the bottom surface of the floor pan body 1 and the drainage portion 3 having the drainage port 7 is formed below the drainage groove 2. The top surface of the drainage portion 3 is the bottom surface of the floor bread body 1. The drain opening 3 is communicated with the drain groove 2, and the lid 5 is arranged on the upper opening of the drain portion 3, and the lid 5 covers the boundary portion of the drain groove 2 with the drain portion 3. Since the protruding cover piece 6 is extended, the cover piece 6 can cover the gap between the lid 5 and the groove bottom of the drain groove 2 formed at the boundary between the drain groove 2 and the drain portion 3.
