Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a unit bathroom wash trap.

[0002]

[Prior Art]

 Conventionally, the above-mentioned trap for the washing place has been constructed so that only the drainage from the washing place is discharged with respect to the drainage part thereof. Therefore, as a pipe connection part provided in the drainage part of the trap, There was only one for the place drain. The drainage from the washroom and the bathtub is generally merged on the way and discharged to the outside of the building in consideration of the cost of piping space and cost of piping materials. In the case of using a trap for a place, as a means for merging the drainage in this way, a joint metal fitting was provided in the middle of the drainage pipe for the washing basin, and the drainage pipe for the bathtub was connected to the joint metal fitting.

[0003]

[Problems to be solved by the device]

 However, according to the above-mentioned conventional configuration, there is a drawback in that the washing trap has to be connected to the joint metal fittings at all times, and the connecting work is troublesome. The present invention eliminates the above-mentioned conventional drawbacks, and when the drainage from the washroom and the bathtub is configured to be discharged through the same pipe, the washroom trap does not need to be connected to the fittings. The purpose is to provide a trap for the field.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the unit bath washing trap according to the present invention is provided with a connecting portion for a drain pipe for a bathtub, and the connecting portion communicates with the drain portion of the trap body through a bypass passage. The feature is that they are connected, and the effects are as follows.

[0005]

That is, since the connection portion for the bathtub drainage pipe is provided and this connection portion is connected to the drainage portion of the trap body through the bypass passage, the bathtub drainage pipe is connected to the connection portion. According to the configuration, the drainage from the bathtub flows into the drainage part of the trap body through the bypass passage, merges with the drainage from the washroom there, and is simultaneously discharged outside the washroom trap by the drainage pipe connected to the drainage part. It flows out. In this way, drainage from the bathtub and washroom can be drained through the same pipe without using fittings, so there is no need to install fittings in the drainage pipe for the washroom, and a trap for the washroom can be used. It is not necessary to connect to the fittings one by one. Moreover, since the connecting portion is connected to the drainage portion of the trap body instead of the drainage inflow portion, for example, even if a large amount of drainage from the washroom flows into the washroom trap, the drainage is The risk of flowing backwards can be prevented.

[0006]

[Effect of the device]

 Therefore, since it is not necessary to connect the washing trap to the fittings one by one, the man-hours for the piping work can be reduced, and the workability of the piping work can be improved correspondingly. Since it is difficult to do so, it was possible to provide a trap for washing the unit bath that can smoothly drain water from the washing basin and the bathtub.

【Example】

 Next, an embodiment of a trap for a unit bath washing room according to the present invention will be described with reference to the drawings.

As shown in FIG. 3, the bathtub 1 is placed on a pedestal 8 arranged on the floor F, and a floor plate 5 forming a washing space is laid on the floor F via pipe-shaped legs 7. A side wall 6 and a ceiling wall 17 are provided, and a faucet metal fitting 2 for a bathtub, a faucet metal fitting 3 for a washing room, and a shower head 4 are provided to form a unit bath.

In the lower part of the bathtub 1 and the floor plate 5, that is, in the lower part of the floor, a drainage pipe Pb for a bathtub, a trap 9 for a washing room, and a main drainage pipe P are arranged.

As shown in FIG. 1, the washing trap 9 includes a bottomed cylindrical trap body 11 having a drainage portion 10, and a sealed water pipe with a flange which is fitted in the trap body 11 at a distance. It consists of 12. The water sealing pipe 12 is attached to the trap body 11 by mounting the flange 12a on the upper edge of the trap body 11. The upper end of the trap body 11 is fitted onto the drainage port 16 of the washroom through the packing 15 so as to guide the drainage water from the washroom, while the lower end of the drainage port 16 is used as the bottom wall of the trap body 11. It is arranged between the drainage unit 10 and the drainage pipe 10 so that the drainage in the sealing pipe 12 passes through the lower end of the sealing pipe 12 for a while and then flows into the drainage unit 10.

According to this configuration, the drainage is always collected at the bottom of the trap body 11 even when the drainage is not performed, and the water surface is located between the lower end of the water sealing pipe 12 and the drainage part 10. Therefore, the pool water can shut off the space on the washroom side from the space in the drainage pipe on the downstream side of the drainage part, and prevent a bad odor on the drainage part side from leaking to the washroom side.

As shown in FIGS. 1 and 2, the trap body 11 is provided with a connection portion 13 for the bathtub drain pipe Pb on the side facing the drain portion 10 in a plan view. 3 is communicatively connected to the drainage section 10 of the trap body 11 via a connection pipe Pa as a bypass passage. The connection pipe Pa is accommodated in the trap body 11 along the circumference of the water sealing pipe 12. A main drain pipe P is connected to the drain portion 10 via a nut 14. Further, the bathtub drain pipe Pb is connected to the connecting portion 13 via a nut 14, and the connecting pipe Pa is fixed to the drain portion 10.

[Other Embodiments] The connecting portion 13 may be provided at any position with respect to the trap body 11, and the connecting pipe Pa may not be housed in the trap body 11. That is, for example, as shown in FIG. 4, the connection part 13 is provided at a position rotated 90 degrees around the axis of the trap body 11 with respect to the drainage part 10, and the connection pipe is provided along the side wall of the trap body 11 from there. Alternatively, Pa may be provided to communicate with the drainage unit 10.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
