  A first embodiment of the present invention will be described with reference to the drawings. The drainage device of the first embodiment shown in FIGS. 1 and 2 is constituted by the members described below.

  The drainage device main body has a bottomed cylindrical deodorizing jar part (2) and an opening of the deodorizing jar part (2) that forms a drainage channel through which drainage overflowing from the deodorant jar part (2) flows. A casing wall (1) having an opening (3) provided with a female screw and a side wall of the deodorizing gutter (2) are connected to a discharge port (10) of a drainage elbow (9) described later. The lower end portion provided in a cylindrical shape in the vertical direction along the inner surface of the casing wall (1) and the branch pipe portion (8) for allowing the drainage from the drainage elbow (9) to flow into the deodorization gutter (2) Is connected to the branch pipe part (8) and the upper end side is provided with a discharge part for discharging the drainage into the drainage flow path, from a first water sealing part (5) formed by a deodorizing gutter part (2) described later. The second sealed part (6) which is an independent sealed part, and the second sealed part from the drainage channel provided in the discharge part of the second sealed part (6) 6) A backflow prevention valve (11) which is a backflow prevention device for preventing the flow to 6) and a discharge port (10) which is provided on a side surface of the casing wall (1) and discharges the wastewater in the drainage channel. . The flange member (12) and the deodorizing cylinder (7) are configured in the same manner as the members described in paragraph 0003 above.

  Said drainage apparatus is used for each member, such as the bathtub described in the said paragraph 0004, a waterproof pan, and drainage piping.

  The drainage device and drainage piping as described above are applied to the bathtub and waterproof pan, which are drainage devices, as follows. First, the male screw and the female screw are screwed while holding the opening periphery of the attachment portion on the washing place (14) side between the opening (3) of the drainage device main body and the flange (13) of the flange member (12). The drainage device main body is attached and fixed to the washing place (14). Next, a pipe member such as a pipe pipe is combined, and the bathtub and the bathtub mounting part (15) and the branch pipe part (8) of the drainage device are connected as the branch pipe part side pipe part. After that, the deodorizing gutter part (2) is attached to the inside of the drainage device main body, and further, the deodorizing gutter part (2) and the deodorizing cylinder are attached to the opening (3) via the flange member (12). (7) forms the first sealed part (5), and the construction of the drainage device and the drainage pipe to the bathtub and the waterproof pan is completed.

  In the drainage pipe including the drainage device piped as described above, when drainage is generated from the washing section (14), the drainage is discharged from the drainage port (4) from the deodorization cylinder (7) and the deodorization gutter part (2). Is finally discharged from the discharge port (10) through the drain port channel (W1) to the sewage-side piping through the first sealing portion (5).

  Moreover, when drainage generate | occur | produces from a bathtub and a bathtub mounting part (15), drainage passes a 2nd sealing part (6) via a branch pipe part side drain piping and a branch pipe part, and also a drainage flow path Is finally discharged from the discharge port (10) through the branch pipe channel (W2) to the sewage side pipe.

  In the above embodiment, the drainage device is provided with a plurality of sealing portions, and the plurality of sealing portions are arranged so that the drainage from each sealing portion is drained in parallel (referred to herein as “ “The drainage from each sealed part is drained in parallel” means that the drainage from each sealed part can be drained to the sewage side without passing through other sealed parts. means).

  As in the conventional example, when drainage from the branch pipe side pipe and drainage from the drain port (5) are combined and processed in one sealed water part, either the branch pipe side pipe or the drain port If there is a large amount of drainage from either side, it will easily cause a reverse flow to the other through the sealing part, but as in the above embodiment, the plurality of sealing parts are connected in parallel with the drainage from each sealing part. If it is arranged to be drained, the distance from the outlet of one sealed part to the outlet (10) of the other sealed part will be longer, and the drainage will rise and fall inside the sealed part. Compared to the conventional example, the amount of water (or water pressure generated by the amount of water) required for the occurrence of the backflow is greatly increased, and the backflow hardly occurs. Particularly in the above embodiment, since the backflow prevention valve, which is a backflow prevention device, is provided at the discharge portion of the second sealing portion (6), even if there is a large amount of drainage from the drainage port, That is, a backflow does not occur on the bathtub mounting portion (15) or the bathtub side.

  Moreover, in the said Example, the waste_water | drain apparatus from which the waste_water | drain from several said sealing part flows was formed in the casing wall (1) which is one casing body, and comprises the whole drainage apparatus compactly. At the same time, members and construction methods necessary for construction, and usage methods can be the same as the conventional drainage device with a trap function, and by reducing the number of newly required members, the product can be made inexpensive. Moreover, the member management is made easy. Further, since the construction method and the usage method are almost the same as the conventional method, it is not necessary to give any education / training to the installer or the user.

  The embodiment of the present invention is as described above, but the present invention is not limited to the above embodiment, and the configuration can be freely changed without changing the gist of the invention.

  For example, in the above embodiment, the second sealing portion (6) is formed integrally with the casing wall (1). However, as in the embodiment shown in FIGS. 3 to 5, the second sealing portion ( 6) may be configured to be detachable from the casing wall (1) or the like. By doing in this way, clogging of the dust etc. which arose in the 2nd water-sealing part (6) can be eliminated easily, and cleaning can be easily performed also at the time of cleaning.

  Moreover, in the said Example, although the backflow prevention valve (11) which is a backflow prevention apparatus is integrated with the 2nd sealing part (6), the backflow prevention valve (11) like the Example shown in FIG. May be configured to be detachable from the second sealed water portion (6) as a member separate from the second sealed water portion (6). Since the backflow prevention device such as the backflow prevention valve (11) usually includes a movable part, it easily breaks or breaks down. However, by making the member detachable, it is possible to replace the member. Functional recovery can be performed.

  In the above embodiment, the backflow prevention device is a hinge-type backflow prevention valve (1). However, as in the embodiment shown in FIG. 7, a soft material that is substantially the same as water and has a small specific gravity. The effect of the present invention can be obtained even if the backflow prevention device is configured by the float valve (16) using the.
