Has been proposed. However, if the drain trap is installed at a position along the back plate of the cabinet as in Patent Documents 1 and 2, there is a problem that it is difficult to maintain the drain trap from the drain port of the wash bowl.

  On the other hand, as shown in Patent Document 3, the present applicant proposes a vanity table that secures a large storage space for the cabinet under the vanity bowl by using a bottle trap as a drain trap of the vanity table. did. However, the bottle trap has a demand for improvement because foreign substances adhere to the flow path as it continues to be used, the diameter of the flow path of the drain pipe becomes narrow, and the water permeability decreases.

  In view of this, the present applicant is considering to secure a large storage space in the cabinet by using an S-shaped drain trap having a small change in flow path diameter instead of the bottle trap. As a bathroom vanity having an S-shaped drain trap, the present applicant, as shown in Patent Document 4, installs an S-shaped drain trap inside the cabinet and bends the connected drain pipe section below the bottom plate of the cabinet. We have proposed a structure connected to the drain pipe connected to the floor drain pipe of the building frame.

  However, the position of the floor drain pipe of the building frame varies depending on where the vanity is installed. For this reason, the drainage pipe of the vanity is laid out according to the drainage position of the building frame, and the drainage pipe is often installed so as to penetrate the central part of the cabinet up and down. It was a narrowing factor.

Alternatively, a drawer can be provided in the storage space 115 instead of the door 116.

  A drain pipe facility 200 is installed inside the cabinet 110. The drain pipe facility 200 has an upstream end connected to the drain 125 of the wash bowl 120, and a downstream end penetrating the bottom plate 114 of the cabinet 110 and in a region below the bottom plate 114. 300, the drainage from the wash bowl 120 can be discharged to the floor drain pipe 300 of the building frame.

  The drain pipe facility 200 has a straight pipe portion 210 connected to the drain 125 of the wash bowl 120 on the upstream side, an S-shaped drain trap 220 connected to the straight pipe section 210 on the upstream side, and a drain trap 220 connected on the upstream side. And a crank-shaped pipe portion 230 connected to the floor drain pipe 300 of the building frame on the downstream side.

  The straight pipe section 210 can connect an overflow channel from the wash bowl 120. Further, if necessary, the straight pipe portion 210 can be constituted by adding two or more pipe materials.

  The S-shaped drain trap 220 includes a U-shaped tube portion 221 bent in a U-shape and an inverted U-shaped tube portion 222 connected to the downstream side of the U-shaped tube portion 221 and bent in an inverted U-shape. ing. Note that the U-shaped tube portion 221 and the inverted U-shaped tube portion 222 are either upstream or downstream, even if the upstream vertical portions 221a and 222a and the downstream vertical portions 221b and 222b have the same length. The vertical part may be longer than the other vertical part.

  The crank-shaped tube portion 230 includes a first vertical tube portion 231 extending in the vertical direction, a horizontal tube portion 232 obtained by bending a lower portion of the first vertical tube portion 231 at a right angle, and a tip of the horizontal tube portion 232 bent vertically downward. The second vertical pipe portion 233 and the second vertical pipe portion 233 are integrally formed without providing a connecting portion therebetween. In addition, it is preferable that the horizontal pipe part 232 is provided with a drainage gradient toward the downstream side.

  The drainage pipe facility 200 includes a first connection part 240 that connects the straight pipe part 210 and the U-shaped pipe part 221, and a second connection part 250 that connects the U-shaped pipe part 221 and the inverted U-shaped pipe part 222. The third connection portion 260 that connects the inverted U-shaped tube portion 222 and the crank-shaped tube portion 230 is connected to be rotatable in the horizontal direction by a fastener such as a cap nut. Therefore, the drainage pipe facility 200 can be installed by appropriately changing the shape by appropriately rotating the first connection part to the third connection part 240, 250, 260 in the horizontal direction.

  The S-shaped drain trap 220 has an inverted U-shape and a vertical portion 221a upstream of the U-shaped tube portion 221 in a state where the U-shaped tube portion 221 and the inverted U-shaped tube portion 222 are connected in the opposite direction by 180 °. The distance in the horizontal direction from the vertical part 222 b on the downstream side of the pipe part 222 is formed to be longer than the distance between the drain 125 of the wash bowl 120 and the surface on the storage space side of the back plate 113 of the cabinet 110. Thereby, by rotating the 4th connection part 270 which connects the 1st connection part-3rd connection part 240,250,260 and the crank-shaped pipe part 230, and the floor drain pipe 300 of a building frame in a horizontal direction suitably, The vertical part 222 b on the downstream side of the inverted U-shaped pipe part 222 and the first vertical pipe part 231 of the crank-shaped pipe part 230 can be installed along the back plate 113 of the cabinet 110. In order to facilitate the connection construction of the third connection portion 260, the vertical portion 222b on the downstream side of the inverted U-shaped tube portion 222, the first vertical tube portion 231 of the crank-shaped tube portion 230, and the back plate of the cabinet 110. It is preferable to provide a small gap without closely contacting 113.

  In addition, the crank-shaped pipe portion 230 has a horizontal distance between the first vertical pipe portion 231 and the second vertical pipe portion 233 such that the storage space side surface of the back plate 113 of the cabinet 110 and the floor drain pipe 300 of the building frame. And longer than the horizontal distance. If the distance between the first vertical pipe portion 231 and the second vertical pipe portion 233 of the crank-shaped pipe portion 230 is set assuming that the floor drain pipe 300 of the building frame is located farthest to the maximum, Even when the position of the floor drain pipe 300 is different, the first connection section to the fourth connection sections 240, 250, 260, and 270 are appropriately rotated in the horizontal direction so that the vertical section 222 b on the downstream side of the inverted U-shaped pipe section 222. And the 1st vertical pipe part 231 of the crank-shaped pipe part 230 can be installed along the back board 113 of the cabinet 110 so that it may adjoin.

  Therefore, by using this drain pipe equipment 200 as the drain pipe of the vanity 100, the storage space 115 of the cabinet 110 can be secured as wide as possible.

  Further, the crank-shaped tube portion 230 is formed so that the second vertical tube portion 233 is shorter than the first vertical tube portion 231. Therefore, the horizontal pipe part 232 and the second vertical pipe part 233 provided between the first vertical pipe part 231 and the second vertical pipe part 233 are installed in a region below the bottom plate 114 inside the cabinet 110. become. Thus, since the horizontal pipe part 232 is not exposed on the bottom plate 114 of the cabinet 110, the storage space 115 of the cabinet 110 is not narrowed. Moreover, since there is no connection part in the crank-shaped pipe part 230, the connection part of the drain pipe in the area | region below the baseplate 114 becomes only the site | part which connects the crank-shaped pipe part 230 to the floor piping 300 of a building frame. Since the crank-shaped pipe part 230 and the floor pipe 300 of the building frame are structured to insert the tip of the second vertical pipe part 233 into the floor pipe 300 of the building frame in the vertical direction and seal the gap, there is a risk of leakage from there. There is almost no. Therefore, it is possible to prevent water leakage from the drainage pipe facility 200 in a region below the bottom plate 114 of the cabinet 110, which tends to delay the discovery of water leakage.

  Next, an installation mode of the drain pipe facility 200 inside the cabinet 110 when the position of the floor drain pipe 300 of the building frame is changed will be described. Drawing 4 is a mimetic diagram showing the installation state of drainage pipe equipment from the upper part inside the cabinet of a vanity stand.

  As shown to Fig.4 (a)-(e), what is the floor drain pipe 300 of a building frame by rotating the 1st connection part-the 4th connection part 240,250,260,270 suitably in a horizontal direction? Even in such a position, the third connecting portion 260 that connects the inverted U-shaped tube portion 222 and the crank-shaped tube portion 230 can be brought close to the back plate 113 of the cabinet 110. In this manner, the vertical part 222b on the downstream side of the inverted U-shaped pipe part 222 and the first vertical pipe part 231 of the crank-shaped pipe part 230 are both installed so as to be close to the back plate 113 of the cabinet 110. Therefore, it is possible to secure a large storage space 115 of the cabinet 110.

As described above, the vanity table 100 (a cabinet with a water tank) in the present embodiment uses the S-shaped drain trap 220, and therefore it is possible to make it difficult for foreign matter to adhere to the drain trap.
Further, in the drainage pipe facility 200 including the drainage trap 220, the U-shaped pipe part 221, the inverted U-shaped pipe part 222, and the crank-shaped pipe part 230 have appropriate lengths, respectively. Since the fourth connecting portions 240, 250, 260, and 270 are respectively rotatable in the horizontal direction, the drainage pipe portion that runs in the vertical direction in the storage space 115 of the cabinet 110 is placed close to the back plate 113 of the cabinet 110. The storage space 115 can be secured widely.
Furthermore, since the connection part of the drain pipe facility itself is not provided below the bottom plate 114 of the cabinet 110, it is possible to prevent water leakage in a region below the bottom plate 114 of the cabinet 110 that is not easily noticeable.

The present invention is not limited to the above-described embodiment, and various modifications can be made.
In the present embodiment, the crank-like pipe portion has been described as an integral body, but a plurality of pipes may be connected so as not to leak.
Moreover, you may enable it to adjust the length of a reverse U-shaped pipe part and a crank-shaped pipe part by the 3rd connection part of a reverse U-shaped pipe part and a crank-shaped pipe part. According to this, it becomes possible to change the height of the wash bowl.
Further, the crank-shaped tube portion may be cut in the middle of the first vertical tube portion. According to this, even when the drainage pipe of the building frame is wall drainage, it becomes possible to use the same drainage pipe equipment as in the case of floor drainage.
