Description

[Detailed description of the invention] "Purpose of the invention" (Field of industrial application) The present invention relates to a new waterproof pan for bathrooms equipped with an underfloor inspection port. The waterproof pan is of a type in which the floor surface for the bathtub is lower than the floor surface of the washing area, making it easier to step over the bathtub from the washing area side during bathing.

(Prior art and its problems) A conventional waterproof pan 1 is shown in FIG. The waterproof pan 1 is installed on the washing area floor 1a and the installation floor 1b for the bathtub 2, which are adjacent to each other.
b is provided at a lower level than the washing area floor 1a. None of this type of waterproof pan 1 was equipped with an inspection opening under the floor, so it was not possible to check for leaks from water supply pipes, hot water supply pipes, drain pipes (all not shown), etc. located at the bottom of the pan. Ta.

By the way, although not shown in the drawings, among other types of waterproof pans in which the washing area floor and the installation floor are provided at approximately the same level, an underfloor inspection port is provided approximately in the center of the installation floor. Something was warm. but,
It was not possible to use a similar underfloor inspection port to the waterproof pan 1 shown in FIG. 3 above. This is because the waterproof pan 1 has a washing area floor 1a and a stationary floor 1b.
This is because the height is different. That is, the waterproof pan 1 must be installed so that the installation height of the washing area floor 1a matches the installation level of the floor 3 on the building side.
The height space between b and the floor slab 4 was extremely narrow. Therefore, even if such an underfloor inspection opening as described above was provided on the installation floor surface 1b, only the portion immediately below it could be seen through the underfloor inspection opening, and it would be of little use. Moreover, when the above-mentioned underfloor inspection opening was provided on the installation floor surface 1b, the following drawbacks occurred. That is,
If hot water overflowing from the bathtub 2 or the like enters onto the installation floor surface 1b, the overflowing hot water drips onto the floor slab 4 through the underfloor inspection hole. Of course, the underfloor inspection port is covered with a lid, but it is impossible to completely seal it. Therefore, mold and pests grew on the floor slab 4, and bad odors were generated from under the floor.

The present invention was developed in view of the above-mentioned circumstances, and allows for inspection of the piping at the bottom of the pan.
Another object of the present invention is to provide a new waterproof pan equipped with an underfloor inspection opening that can completely prevent overflowing hot water from a bathtub or the like from reaching the floor slab.

"Effect of the invention" (Means for solving the problem) The gist of the waterproof pan is that the washing area floor and the bathtub installation floor installed at a lower level than the washing area floor are adjacent to each other. In the waterproof pan for a bathroom, which is provided with an upright wall interposed in the adjacent portion, the upright wall is provided with an underfloor inspection port.

(Function) The underfloor inspection port is provided in an upright wall adjacent to the washing area floor and the stationary floor. Therefore, if you look through the underfloor inspection opening, you can see a panoramic view of the lower part of the washing area floor. In other words, in addition to checking for leaks in the water supply pipes, hot water supply pipes, and drain pipes located at the bottom of the pan,
Maintenance is also possible within reach.
It also becomes possible to maintain auxiliary heaters, bubble generators, etc. attached to bathtubs and the like. Furthermore, even when installing the waterproof pan of the present invention, it is possible to operate the height adjusting legs provided within easy reach.

(Example) The present invention will be described below based on drawings showing examples thereof.

FIG. 1 is a perspective view showing the waterproof pan of the present invention. In the waterproof pan of the present invention, an underfloor inspection port 8 is provided in an upright wall 7 provided adjacent to a washing area floor 5 and a standing floor 6 for a bathtub (not shown). Note that this figure shows a state in which the lid 8a is attached to the underfloor inspection port 8.

The underfloor inspection opening 8 is located approximately at the center of the upright wall 7, and its opening width occupies approximately 1/3 of the total length of the upright wall 7. FIG. 2 is a side sectional view of the upright wall 7, showing the cover 8 from the underfloor inspection opening 8.
The figure shows the state with a removed. The opening height of the underfloor inspection port 8 extends approximately to the entire height of the upright wall 7. However, the lower edge of the underfloor inspection opening 8 is kept at a height of 10 mm or more from the lower end of the upright wall 7. This holding height is the permissible water inundation level on the installation floor 6, and is designed to prevent overflowing hot water from accumulating on the installation floor 6 in an amount exceeding 10 mm. because,
As shown in FIG. 1, the upright wall 7 is not only provided with a drainage hole 7a for draining overflowing hot water that has entered onto the installation floor 6, but also has a drainage hole 7a unique to the bathtub (not shown). This is because a tube insertion hole 7b is provided through which a tube (not shown) is inserted. That is, the installation floor surface 6 is originally designed to prevent a large amount of hot water from entering. Therefore, as shown in FIG. 2, even if the lid 8a remains removed, the overflowing hot water that has entered the installation floor surface 6 will not leak into the floor slab. The lid 8a is screwed to the upright wall 7, and reference numeral 9 designates a frame member that serves both as a screw receiver and as a reinforcement for the underfloor inspection port 8.

By the way, as mentioned above, the overflowing hot water on the installation floor 6 is drained from the drain hole 7a provided on the side (upright wall 7) of the installation floor 6, as shown in FIG. Further, the bathtub placed on the floor surface 6 is provided with its own drain pipe (not shown). That is, no piping portion is provided below the stationary floor surface 6, and all of the piping portions are concentrated at the lower portion of the washing area floor surface 5. Therefore,
From the underfloor inspection port 8 provided in the upright wall 7, the entire piping section can be seen. Moreover, the drain hole 7a and the pipe insertion hole 7b are connected to the underfloor inspection opening 8.
Since it is located right next to the underfloor inspection port 8, it is also possible to perform maintenance on each drain pipe (not shown) when water leaks from the underfloor inspection port 8.

(Study of Alternative Embodiments) The construction of the drainage hole 7a and the tube insertion hole 7b in the upright wall 7 is not limited. In this case, the permissible inundation water level of the installation floor surface 6 naturally increases, but in conjunction with this, the lower edge of the opening of the underfloor inspection port 8 also needs to be raised. Further, the installation floor surface 6 may also have no drainage holes.
Of course, the attachment structure of the lid 8a to the underfloor inspection port 8, its material, etc. are not limited at all. In this way, the configuration and shape of the waterproof pan of the present invention can be changed as appropriate depending on the embodiment.

``Effect of the invention'' As is clear from the above explanation, according to the bathroom waterproof pan equipped with an underfloor inspection port according to the present invention, the water supply pipe arranged at the bottom of the pan can be easily removed by simply removing the bathtub. , can check for leaks in hot water pipes, drain pipes, etc. Therefore, unlike conventional waterproof pans, there is no need to remove the bathtub and wall panels and take the trouble of raising the waterproof pan. Since the inspection work can be easily performed in this way, periodic inspections are possible, which has the advantage of preventing water leakage accidents, and detecting water leakage accidents earlier, so that they can be dealt with while the damage is still minor. Further, since the underfloor inspection port is provided in the upright wall and opens vertically, the depth area visible from the underfloor inspection port is expanded, and some maintenance can be carried out within easy reach. Furthermore, when installing the proposed waterproof pan, the height-adjustable legs can be operated and mortar placed through the inspection opening under the floor, making the installation process easier. .
