Was.

[0003]

For this reason, in the former case, the contractor must install an inspection port on the floor of the dressing room, and if the distance between the inspection port and the connection portion is long, a sufficient inspection is performed. Not only was it not possible, but the construction cost of the housing was also increased by the cost of installing the inspection door. In the case of the latter, an opening is provided in the floor pan in the bathroom where hot and cold water is splashed.Therefore, there is always a danger of water leaking out of the bathroom, and sufficient water stoppage measures must be taken. There have been problems such as the cost of materials related to the countermeasures, the cost of processing floor pans, and the cost of materials for inspection lids and the like.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. In order to check for a leak at a connection between a drain trap of a bathroom unit and a drain pipe, a floor of a dressing room or a bathtub in a bathroom is placed. It is an object of the present invention to provide a bathroom unit provided with a drain trap capable of easily checking the presence / absence of water leakage from a bathroom without providing an inspection port in a floor pan on the side to be cleaned.

In order to achieve the above object, the present invention provides a drain trap comprising a drain trap main body, a water sealing tube, a fastening flange, a packing and the like, and the drain trap according to the present invention. In a bathroom unit provided with a drain pipe to be connected, a bathroom unit provided with a drain trap characterized in that at least a color of a drain trap body is transparent.

According to this configuration, an inspection port is provided on a floor of a dressing room floor or a floor pan on which a bathtub is placed in order to check for a leak at a connection portion between a drain trap and a drain pipe of a bathroom unit. Even without doing so, the inspector removes the water bottle separately provided inside the drain trap from the bathroom and looks into the transparent drain trap body from the diagonally upper part of the drain trap, or a hand mirror etc. By inserting this into the drain trap body and using the reflection of the mirror, it is possible to easily check whether or not there is water leakage between the drain trap and the drain pipe connection.

According to a second aspect of the present invention, there is provided a bathroom unit provided with a drain trap according to the first aspect, wherein the color of the drain pipe is transparent. According to this configuration, since the drainage pipe is transparent, the visible range is widened, and inspection of the connection between the drainage trap and the drainage pipe is further facilitated.

A bathroom equipped with a drain trap according to claim 1 or 2, wherein said drain pipe has a flange near the end of the drain port when fully inserted into the drain trap connection port. A unit is provided. According to such a configuration, water leakage from the connection portion hits the flange portion,
Since it falls on the building floor near the flange, not only can water leakage be prevented from spreading far away, but also the inspection range for the presence or absence of water leakage is limited to the vicinity of the connection part, and a reliable inspection can be performed.

[0009]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a sectional view of a main part of a drain trap A used in a bathroom unit Y of the present invention. FIG. 2 is a plan view of the bathroom unit Y of the present invention. In FIG. 2, the bathroom unit Y includes a floor pan 1, a bathtub 2, a wall panel 3, a ceiling panel (not shown), and the like, and a drain trap A is installed at a substantially central portion of the bathroom unit Y.

As shown in FIG. 1, the drain trap A of the bathroom unit Y is provided with an opening in the floor 11 on the washing side, and is attached via a fastening flange 6, a packing 7, and the like. Further, the upper part is covered with a detachable trap cover 8, and the drainage from the washing floor 11 is guided to a drain trap A through a notch 9 provided in the trap cover 8 and drained. Drainage of the bathtub 2 and drainage overflowing on the bathtub side floor 21 are drained by connecting the bathtub drainage pipe 22 to the drainage trap A.

As a material of the drain trap A, a resin such as ABS is generally used. In addition, the shape is a hollow substantially cylindrical shape, a detachable water sealing tube 10 is provided inside, a peripheral wall 13 has a connection port 15 for connecting a drain pipe 14, and the drain pipe 14 has a predetermined shape. It is inserted into the connection port 15 by the length. In order to check for the presence or absence of water leakage from the connection port 15, it is necessary to remove the trap cover 8 and remove the water sealing tube 10 from the interior of the bathroom in advance. further,
Since the sealing water (not shown) is always stored, it is necessary to discharge the sealing water using a rag or the like.

FIG. 3 is a cross-sectional view of the drain trap A showing a water leakage check operation in a state where the trap cover 8 and the water bottle 10 are removed. In the unlikely event that there is a leak 50 from the connection port 15, the inspector 30 can look into the drain trap main body 12 from diagonally above the drain trap A and irradiate a flashlight (not shown) or the like. Since the trap body 12 is transparent, the drain connection port 15 and the building floor 40 near the drain connection port can be inspected. Furthermore, if the inspection mirrors 31 and 32 such as hand mirrors are inserted into the drain trap body 12 for inspection, a wider range can be easily inspected.

Furthermore, if the color of the drain pipe 14 is made transparent,
Since the condition of the building floor surface 30 can be confirmed also from the drain pipe connection port 15, it is possible to further confirm a wide range. The drain pipe 14 connected to the drain trap A is designed to have a flange 16 near the end of the drain port when the drain pipe 14 is sufficiently inserted into the drain trap connection port 15. This collar 16
Prevents the water leakage 50 from diffusing from the drain trap connection port 15 and leaks around the building floor 40 near the connection port.
Can be checked through. Further, since the flange 16 has a height that does not interfere with the reinforcing ribs (not shown) on the back side of the floor pan 1 and is provided integrally with or separately from the drain pipe 14, a problem may occur during construction. No, drain trap connection port 1
It also serves as a guide when confirming whether the drain pipe 14 is sufficiently inserted into 5.

The term "transparent" in the present invention encompasses all materials having a degree of transparency at which water leakage as shown in the examples can be confirmed, regardless of whether or not the resin is colored.
The bathroom unit of the present invention includes a shower unit,
It also includes a sanitary equipment room equipped with a waste trap such as a Western-style unit.

[0015]

According to the present invention, the following effects are exhibited by the above configuration. According to the first aspect, it is possible to easily check the presence or absence of water leakage at the connection between the drain trap and the drain pipe from the bathroom through the drain trap. Therefore, there is no need to provide an inspection port in the floor of the dressing room or on the floor pan on which the bathtub in the bathroom is placed, and no extra cost is required. Further, the trap can be manufactured with the same mold and manufacturing conditions as the conventional colored opaque trap, and there is no need to newly manufacture a mold, so that initial capital investment is not required.

In the second aspect, in addition to the first aspect, the drainage pipe is also transparent, so that it is easy to check for the presence or absence of water leakage.

According to the third aspect of the present invention, since the water leakage from the connection portion hits the flange and falls on the building floor near the flange, not only can the water leakage be prevented from being diffused far away, but also the inspection range for the presence or absence of the water leakage can be reduced. Only the vicinity of the part can be checked reliably.
