Abstract

PROBLEM TO BE SOLVED: To provide a door for a bathroom, which has resistance to soiling and good cleanability, and can acquire innovative design properties. SOLUTION: A waterproof floor pan is equipped with a bathtub installing part and a washing place part. In the bathtub installing part, a piping inserting part for water supply and hot-water supply is located higher than an upstream position of the washing place part, and taken as a step part whose top surface forms a flat surface. An opening provided in the bathtub installing part of the waterproof floor pan is installed in a higher position than an upstream part of a floor of a washing place. Consequently, hot water is not stored to the height of the piping inserting part so as to eliminate fear of leakage to downstairs, because a water level rises only up to the height of the upstream part, even if the hot water is stored on a bottom surface of a floor due to clogging of a trap and the like during discharge of the hot water in the bathtub, and even if waterproof rubber packing and the floor pan are not completely waterproofed due to a constructor's mistake, variations during mounting and deterioration of the rubber packing.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to easily perform piping work and inspection of water supply pipes and hot water supply pipes for a unit bath from the indoor side, and to absorb variations in construction and deterioration of rubber packing. The present invention relates to a floor structure of a unit bath that ensures that water leakage does not occur.

[0002]

2. Description of the Related Art When a system bathroom is provided in a 2 × 4 (two-by-four) structure house, since the house has a wooden frame structure, a space obtained between columns is closed by a wall panel. For this reason, there is not enough space for piping such as water supply pipes and hot water supply pipes between the side wall of the bathroom and the skeleton wall of the building, so adjust the height of the floor pan of the bathroom with legs to make space under the floor pan. It was necessary to arrange these pipes in this space beforehand. For this reason, conventionally, an opening was provided on the bottom of the washing pan on the floor pan of the system bathroom, and a water supply pipe and a hot water supply pipe were set up in this opening, and were constituted by rubber packing. (E.g. 8-2097
No. 61).

[0003]

However, the above-mentioned prior art has the following disadvantages. When draining hot water accumulated in the bathtub, if the drainage outlet is clogged, hot water accumulates on the bottom of the floor pan. In the worst case, the water level increases, and it is considered that the water level rises from above the water on the floor on the washing side until hot water overflows at the dressing room. At that time, it is considered that the water tightness between the floor pan and the rubber packing becomes incomplete due to an incorrect mounting of the rubber packing or aging, and hot water accumulated on the bottom surface of the floor pan leaks from the opening to the downstairs. When it leaks, it cannot be confirmed because it is behind the bathtub. In addition, when performing the maintenance of the piping, the bath apron is removed, but the connection between the floor pan and the rubber packing is below the floor on the washing place side, so that maintenance is difficult.

An object of the present invention is to provide a floor structure of a unit bath which does not depend on construction variations and durability of packing and does not have to worry about water leakage, and also has improved maintainability.

[0005]

Means for Solving the Problems To solve the above problems, a first aspect of the present invention is a waterproof floor pan having a bathtub installation section and a washing place section, wherein the bathtub installation section has a water supply and a hot water supply. The pipe insertion portion is higher than the water position of the washing section, and the pipe insertion portion is a step having an upper surface forming a flat surface.

According to the above invention, when the hot water in the bathtub is drained,
Even if hot water accumulates on the floor bottom due to trap clogging etc., the opening provided in the bath tub installation part of the waterproof floor pan was installed at a position higher than the water level on the washing floor, so the waterproof rubber packing and floor pan were mistaken by the installer. Even when water is not completely waterproofed due to variations during installation or deterioration of the rubber packing, the water level rises only up to the water at the maximum, so that hot water does not accumulate up to the pipe penetration and there is no fear of water leaking downstairs.

According to a second aspect of the present invention, since the pipe insertion portion is formed on the short side of the bathtub and faces with the apron removed, the step having an opening on the upper surface has an end on the long side of the bathtub. Since the opening and the bank are almost the same height, the bus apron can be removed for easy maintenance.

According to a third aspect of the present invention, since the pipe insertion portion is formed below the bus apron portion and faces with the apron portion removed, the bus apron is removed because the opening portion and the bank portion have substantially the same height. Maintenance is easy.
