[0005]

If the floor pan proposed here is used, it is easy to connect the drain trap below the floor pan to the drain pipe and to adjust the level of the floor pan. Further, since the floor pan body is separate from the upper floor, there is an advantage that it is lighter and easier to handle. However, since the floor pan has a large opening over substantially the entire surface of the washing place, it is difficult to maintain the strength of the floor of the washing place, and the washing place is easily deformed when a person enters the washing place. In order to maintain the required strength so as not to be deformed, it is necessary to take measures such as increasing the thickness of the upper floor, providing a large number of reinforcing ribs, and further strengthening the upper floor support portion in the lower floor. An object of the present invention is a floor pan of a bathroom unit, in which connection between a drain trap below the floor pan and a drain pipe installed on the floor of a building frame, level adjustment of the floor pan, and the like, are easy, and It is an object of the present invention to provide a washing floor pan which can easily maintain the strength of the section (that is, the washing place is hardly deformed even when a person gets on the washing place).

[0006]

Means for Solving the Problems In order to achieve the above object, the present invention has the following configuration. That is, the present invention is a floor pan composed of a bathtub mounting place and a washing floor or a washing floor pan formed integrally with a bathtub, wherein the washing floor has a lower floor 3 having a plurality of openings 3a, It has a double structure with a non-permeable upper floor (single plate) 2 which can cover almost the entire surface of the washing floor (excluding the drain outlet of the washing room), and the upper floor 2 is placed on the lower floor 3. This is a floor pan 1 having a fixed structure.

Here, on the back surface side of the upper floor 2, a closing structure 2a (an annular convex shape conforming to the shape around the opening) opposing and closing the opening (plurality) 3a of the lower floor 3. Projections or annular concave grooves). After placing the upper floor 2 on the lower floor 3 and firmly fixing both,
The lower floor opening 3a is water-tightly sealed by the action of the closing auxiliary member (packings) 4 sandwiched in advance.

Further, reinforcing ribs 2b can be provided vertically and horizontally (or in oblique directions) on the back side of the upper floor 2. Lower floor 3
It is preferable to provide a reinforcing rib also on the back side of the.

A reinforcing rib 2 provided on the back side of the upper floor 2
b or a part thereof may also serve as a closing structure for closing the opening 3a of the lower floor 3.

[0010] Further, since the bathroom space is generally rectangular in plan view, the floor of the lower floor 3 is also generally rectangular in plan view. Therefore, the plurality of openings 3a provided in the lower floor 3 are:
It is preferable that the lower floor 3 is formed to be large at the center of each part which is equally divided into n lines (in a plan view). Where n is
It is preferably about 2 to 6 (integer), and more preferably 2. When the lower floor 3 is bisected in plan view, 2
The straight line that divides is preferably a straight line that is parallel to the short side of the washing floor, and the shape of the opening 3a is preferably substantially rectangular (in addition to substantially rectangular, in some cases, triangular, polygonal, circular, or elliptical). Etc.)

Further, the upper floor 2 is fixed to the lower floor 3 by fitting a convex portion or a concave portion provided around the lower floor with a concave portion or a convex portion provided on the back surface around the upper floor, or by fixing a fixing tool (screw screw). etc)
And the fixing method is not particularly limited. Further, in order to completely waterproof the fitting portion and the contact portion, it is preferable to use a closing auxiliary material such as a packing or a caulking material.

The present invention also relates to a bathroom unit provided with the floor pan.

[0013]

According to the present invention, water leakage from a plurality of openings in the lower floor is prevented by any of the following. a) The upper surface of the lower floor is provided with a downward slope toward the drain, and the rising wall 3b is provided around the opening of the lower floor. Then, the hot water on the upper surface of the lower floor does not leak from the opening, but goes to the washing outlet. b) Separately prepared lid material and closure auxiliary material (packings),
Alternatively, the lower floor opening is formed by using a closing structure (a convex protrusion or a concave groove formed in accordance with a shape around the opening) and a closing auxiliary member (packings) on the back surface of the upper floor provided to face the opening. Seal water tightly. c) When placing and fixing the upper floor on the lower floor, the contact portion between the lower surface around the upper floor and the lower surface around the upper floor is sealed watertight using packings or caulking material.

If the waterproofing of the above c) is perfect,
The waterproofing of b) is not always necessary. On the other hand, even if the waterproofing of the above b) is complete, if the waterproofing of the above c) is incomplete, the hot water flowing down from the upper floor goes over the lower floor, and the hot water stays there, and if it passes for many days, it becomes impossible. It becomes hygiene and is not preferred.
Therefore, the best solution is to waterproof all of the above a), b) and c), and the next best solution is to waterproof together the above a) and c).

Further, the washing area of the floor pan 1 of the present invention can be divided into an upper floor 2 and a lower floor 3, and the weight of the floor pan body not including the upper floor 2 is generally larger than that of the conventional integrally formed floor pan. It's lighter. Therefore, it is easy to transport and carry in the bathroom space. In addition, after the floor pan is carried into the bathroom space, the lower floor opening 3a is used without connecting the upper floor 2 to connect the drain trap below the floor pan with the drain pipe installed on the floor of the building frame and the floor. Since you can adjust the pan level,
Installation work is easy. Also, the lower floor does not have a large opening over the entire washing area, but instead has a plurality of (two or more) openings 3a, and the floor between the openings is a lower floor (usually an integral part). (Formed) and has the effect of maintaining the strength of the entire lower floor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described more specifically with reference to the accompanying drawings. FIG. 1 shows an example of the floor pan according to the present invention (before the upper floor is fixed to the lower floor). FIG.
FIG. 3 is a perspective view of the floor pan when the upper floor 2 is fixed to the lower floor 3, FIG. 3 is a perspective view of the back side of the upper floor of FIG. 1, and FIG.
FIG.

The illustrated floor pan 1 is a floor pan composed of a bathtub mounting place and a washing floor, and the washing floor 3 (that is, the lower floor) is provided with a drain port on the side close to the bathtub. Two rectangular openings 3a along the longitudinal direction of the bathtub
Is provided. Further, the lower floor 3 is formed so as to have a gradient, and the edge of the opening 3a (so that even if hot water enters the lower floor, it does not flow down from the opening as it is).
A rising wall 3b is formed, and a closing auxiliary member 5 such as a rubber packing is arranged around the rising wall.

The upper floor 2 is a non-permeable single-plate upper floor capable of covering almost the entire washing area except for a drain port.
The upper surface is provided with an uneven pattern or a picture pattern for exhibiting anti-slip, aesthetics and design, and a downward slope is formed toward the drain. On the back side of the upper floor 2, reinforcing ribs 2b are formed vertically and horizontally. Here, in addition to the role of ensuring the strength of the upper floor, the reinforcing rib 2b can also serve as a closing portion 2a (projection) for closing the lower floor opening, and is arranged around the lower floor opening. In cooperation with the closed auxiliary member 4 (packings), the opening is completely waterproofed. The reinforcing rib 2b may be not only vertically and horizontally but also in an oblique direction (X shape). Note that an annular protrusion (convex portion) different from the reinforcing rib may be provided on the back surface side of the upper floor, and an annular groove-shaped concave portion may be provided around the lower floor opening 3a so that both are fitted. Alternatively, an annular concave groove may be provided on the back side of the upper floor, and may be fitted with an annular rising wall rising around the lower floor opening.

The upper floor 2 is placed on a floor pan (lower floor 3), and the upper floor 2 is fixed to the lower floor 3. If the lower floor opening 3a is completely closed, strict watertightness at the contact portion between the lower floor 3 and the periphery of the upper floor 2 may be unnecessary. This is because the hot water that has fallen on the lower floor 3 flows down to the drain along a downward slope. However, in consideration of cleanliness and cleaning on the lower floor 3, it is preferable that hot water does not flow from the upper floor 2 to the lower floor 3. In order to prevent hot water from flowing from the upper floor 2 to the lower floor 3, when placing and fixing the upper floor 2 on the lower floor 3,
A fitting portion or a contact portion between the lower surface of the upper floor 2 and the lower surface of the lower floor 3 is sealed in a watertight manner by using packing or a caulking material 5. Instead of fitting the convex portion to the concave portion, it may be firmly fixed by a fixing tool such as screws.
