JP 2001-214488 A

However, the above conventional example has the following problems.
In the drainage pipe, the lower part of the drainage adapter member is opened, and an inclined part protruding outwardly downward along the peripheral edge is provided on the outer periphery of the lower opening. It is comprised so that may contact | abut.
If comprised in this way, a plate nut member and a drain plug main body will be screwed together, and the following 1. 2. This produces the effect of
1. The inclination of the triangular packing and the inclined portion of the drainage adapter member are strongly pressed and come into watertight contact.
2. The stress that is sandwiched between the drainage adapter member and the plate nut member and that is compressed in the vertical direction, acting on the triangular packing, is converted into the stress toward the inner diameter direction by the inclination of the triangular packing. As a result, the space between the outer peripheral surface of the drain plug main body and the triangular packing is strongly pressed, and both come into watertight contact.
As a result, the opening below the drainage adapter is watertightly closed by the drainage plug body and the triangular packing, thereby preventing water leakage.
However, when configured as described above, the inclination of the triangular packing that substantially functions as the bottom surface of the drainage adapter member is configured to be inclined downward from the inner peripheral side toward the outer peripheral side, so as shown in FIG. From the upper end of the triangular packing to the inner peripheral surface of the cylindrical portion of the drainage adapter member, accumulated water of drainage is generated.

Furthermore, in most cases, the lower end of the opening provided on the side surface of the drain plug main body is disposed above the upper end of the triangular packing. This is because water leakage occurs from the lower end of the opening if the lower end of the opening is disposed below the lower end of the triangular packing when the construction is completed. The thickness of the peripheral edge of the mounting hole varies depending on the wash bowl, such as a metal wash bowl, which is about 2 to 3 mm, whereas a wash bowl made of resin such as artificial marble is 10 mm or more. Depending on the thickness of the peripheral edge of the mounting hole, the height position of the triangular packing is also shifted. Therefore, regardless of the thickness around the mounting hole, the lower end of the opening is sufficiently high so that the lower end of the opening is always above the lower end of the triangular packing, for example, the thickness around the mounting hole is 0. What kind of wash bowl the millimeter packing, so that the upper end of the triangular packing is at the same height as the lower end of the opening, with the flange member and the upper surface of the drainage adapter member in contact with each other without being attached to the mounting hole Even when the drain plug main body is attached to the bottom of the triangular packing, the lower end of the opening is higher than the upper end of the triangular packing so that water leakage does not occur from the lower end of the triangular packing. This is an effective method for preventing water leakage, but instead, as shown in FIG. 7, as shown in FIG. 7, the drainage pools up to the lower end of the opening which is higher than the upper end of the triangular packing inside the drainage adapter member. The problem of producing a part arises.
Wastewater is sewage used for washing, etc. For example, dirt such as bacteria and slime, or chemical components such as organic solvents and detergents may be mixed. The drainage adapter member and the triangular packing are deteriorated, deteriorated and damaged by organic solvents and chemical components.

Since the drainage pipe provided with the drainage adapter member of the present invention is configured as described above, the following excellent effects are exhibited.
1) In the present invention described in claim 1,
When the mounting to the tank is completed, the bottom wall portion upper surface is disposed above the lower end of the opening, and the upper surface of the bottom wall portion has a shape that is flat or inclined toward the insertion hole.
The drainage that flowed into the cylindrical portion of the drainage adapter member flowed into the drainage drainage flow path of the drainage plug body from the opening and was processed, so that it did not stay in the drainage adapter member.

A piping structure in which no water is generated can be achieved.

Embodiments of the present invention will be described below with reference to the drawings.
The embodiment of the present invention shown in FIGS. 1 to 5 includes a wash bowl S, a drain plug body 1, a drain adapter member 5, a triangular packing 9, a plate nut member 10, a cap nut member 12, and a pipe member described below. , Overflow drain plug 14, overflow elbow 15, and other members.
The wash bowl S is a bottomed box-like tank body, and includes an attachment hole for attaching the drain plug body 1 to the bottom surface, and an overflow attachment hole for attaching the overflow drain plug 14 and the overflow elbow 15 above the side surface. .
The drain plug body 1 is cylindrical and has a drain port 2 through which drainage in the tank flows into the upper end and a drain plug drain channel 3 through which drainage flows, and drainage flows into the side surface of the cylindrical portion. Opening 4 is provided. Further, a flange portion 13 projecting outward is provided on the outer periphery of the upper end of the drain plug main body 1, and a male screw portion 1 a in which a male screw is threaded below the side surface is provided.
The drainage adapter member 5 has a cylindrical shape having a cylindrical shape and a bottom wall 7 integrally formed at the lower end thereof, an insertion hole 8 through which the drainage plug main body 1 provided at the center of the bottom wall 7 is inserted, Furthermore, it is comprised from the inflow pipe 6 which introduces the waste_water | drain from the other drainage piping provided in the cylindrical part 5a side surface.
Further, the upper surface of the bottom wall portion 7 is provided with a downward slope toward the insertion hole 8.
In addition, a contact surface portion 5b is provided on the outer periphery of the opening above the drainage adapter member 5 so as to continuously protrude outward along the periphery, and above the contact surface portion 5b, the contact surface portion 5b An annular packing 16 is provided between the abutting surface portion 5b and the back surface of the wash bowl S, which is disposed between the back surface of the bottom wall portion 7 of the wash bowl S which is a tank body.
Moreover, the space | interval of the outer peripheral surface used as the outer surface of the part arrange | positioned in the insertion hole 8 vicinity of the drainage adapter member 5 of the drain plug main body 1 and the inner peripheral surface used as the inner surface of the insertion hole 8 of this drainage adapter member 5 Is such that a gap is generated by 0.5 millimeters, both have substantially the same diameter, and the inner peripheral surface of the insertion hole 8 of the drainage adapter member 5 has a slightly larger diameter.
The triangular packing 9 is a ring-shaped member having a substantially right-angled isosceles triangle cross section, and is configured such that the inner peripheral surface abuts on the outer peripheral surface of the drain plug main body 1 and the bottom surface a plate nut member 10 described later. In addition, the outer side surface is provided with an inclination 9 a that contacts the bottom surface of the drainage adapter member 5.
The plate nut member 10 has a substantially cylindrical shape and is provided with a female screw portion 11 provided with a female screw that is screwed into the male screw portion 1a of the drain plug main body 1 and projects outwardly on the outer periphery of one end. A plate-like portion 10a is provided.
The cap nut member 12 has a substantially cylindrical shape and is provided with a female screw portion 11 having a female screw threadedly engaged with the male screw portion 1a of the drain plug main body 1, and projects inwardly on the inner periphery of one end. An inner flange portion 12a is provided.
The overflow drain plug 14 is cylindrical and includes an overflow drain port 14a through which drainage in the tank flows into one end, and an overflow drain plug drain channel 14b through which drainage flows.
The overflow elbow 15 is a member having an overflow discharge port 15a connected to the overflow drain plug 14. The overflow elbow 15 passes through the overflow drain port 14a and the overflow drain plug 14 and passes through the overflow drain port 14a. It is discharged from the outlet 15a.
The pipe member is a member for connecting the above-described members, and is connected to the drain plug main body 1 via the flexible overflow drain pipe P1 that connects the overflow outlet 15a and the inflow hall, the cap nut member 12, and the like. A downstream drainage pipe P2 or the like connecting the sewage side pipe is used.

Further, the drain plug main body 1, the triangular packing 9, the plate nut member 10, and the cap nut member 12 are disposed on the bottom wall of the drain adapter above the lower end of the opening 4 when the attachment to the wash bowl S, which is a tank body, is completed. It is designed so that the part 7 is arranged. Specifically, as shown in FIG. 4, the drainage adapter member 5, the triangular packing 9, and the plate nut member 10 are sequentially inserted into the drainage plug body 1 from above, and the upper surface of the bottom wall 7 is the opening of the drainage plug body 1. If it is located below the lower end of the part 4,
The height dimension of each member is designed and configured so that an appropriate mounting space for the cap nut member 12 does not occur in the male screw portion 1a of the drain plug body 1.
Designing at such a height position is based on the total height when, for example, the triangular packing 9 and the plate nut member 10 are combined by shifting the lower end position of the opening 4 of the drain plug body 1 upward or downward. This can be easily achieved by adjusting and designing the height width of the lower end of the opening 4 of the drain plug main body 1 and the lower end of the male screw portion 1a. If necessary, it can be adjusted by designing the overall height of the plate nut member 10 to be higher or lower.
Here, “appropriately attaching the cap nut member 12” does not simply mean “the screw thread of the male screw portion that can attach the cap nut member 12”, but “the cap nut member 12”. This means that it is possible to connect the pipe to the sewage side at the lower end of the drain plug main body 1 without causing problems such as water leakage.

Each member configured as described above is applied to a wash bowl S of a wash basin, which is a tank body, in the same manner as the conventional example described in paragraph 0005. At this time, if the vertical thickness of the peripheral edge of the mounting hole is thinner than the wash bowl S in FIG. 4, the triangular packing 9 and the plate nut member 10 are disposed on the upper side as shown in FIG. 1. As a result, since the upper surface of the bottom wall portion 7 of the drainage adapter member 5 and the upper end of the triangular packing 9 are arranged above the lower end of the opening 4, the drainage in the drainage adapter member 5 is drained from the opening 4. All of the water flows into the plug drainage flow path 3 and the drainage does not stay inside. In the construction, as shown in FIG. 5, when the peripheral edge of the mounting hole is thick and the upper end of the triangular packing 9 is arranged below the lower end of the drain plug body 1, that is, the upper end of the triangular packing 9. Even in the case where accumulated water W is generated due to the height position between the bottom end of the drain plug body 1 and the opening 4 of the drain plug body 1, the portion disposed near the insertion hole 8 of the drain adapter member 5 of the drain plug body 1 The outer peripheral surface serving as the outer surface and the inner peripheral surface serving as the inner surface of the insertion hole 8 of the drainage adapter member 5 are such that there is a gap of 0.5 millimeters, and both have almost the same diameter, so that they almost accumulate. Water W does not occur.
In addition, as shown in FIG. 5, when the upper end of the triangular packing 9 is disposed below the lower end of the opening 4 of the drain plug main body 1, Due to the height relationship at the time of design, the male screw portion 1a that is an attachment margin for attaching the cap nut member 12 is not exposed for the length necessary for the attachment, and the cap nut member 12 cannot be attached. It can prevent that the drainage pipe provided with drainage adapter member 5 which produces water W arises.
In addition, when the situation which cannot be constructed in this way arises, prepare each member such as the drain plug main body 1 which adopts the present invention and separately designed the dimensions of each part to an appropriate size, and perform the proper construction again. By performing, drainage piping provided with the drainage adapter member 5 which does not produce the accumulated water W can be performed.

In the drainage pipe of the wash bowl S piped as described above, when drainage is generated in the wash bowl S that is a tank body, the drainage flows from the drain port 2 on the bottom face of the wash bowl S to the drain plug drain channel 3 and the downstream side. Waste water is finally discharged to the sewage side through the drain pipe P2.
Further, if the drain port 2 is closed with a valve or the like so that drainage is accumulated in the wash bowl S, the drainage in the wash bowl S overflows when the water level in the wash bowl S reaches the lower end of the overflow drain port 14a. It flows into the inside of the cylindrical part 5 a from the drain outlet 14 a through the overflow drain plug 14 flow path, the overflow elbow 15, the overflow outlet 15 a, the overflow drain pipe P 1, and the inlet pipe 6 of the drain adapter member 5. Furthermore, it passes over the lower end of the opening 4 of the drain plug body 1 and flows into the drain plug body 1 flow path, and finally the drainage is discharged to the sewage side via the downstream drain pipe P2.
As described above, the waste water generated in the wash bowl S, which is a tank body, is discharged from the drain port 2 or the overflow drain port 14a to the sewage side.
Furthermore, since the wastewater that has flowed into the cylinder portion of the drainage adapter flows into the drainage drainage channel 3 of the drainage plug body 1 through the opening 4 and is processed, it no longer stays in the drainage adapter. It is possible to solve the problem that the drainage adapter member 5 and the triangular packing 9 are deteriorated, deteriorated and damaged due to hygiene or due to organic solvents or chemical components.

  The embodiments of the present invention are as described above, but the present invention is not limited to the above-described embodiments, and can be freely changed without departing from the scope of the present invention. For example, in the embodiment of the present invention, the upper surface of the bottom wall portion 7 of the drainage adapter member 5 is configured to be inclined toward the insertion hole 8, but the present invention is not limited to the above configuration, You may comprise the bottom wall part 7 upper surface in flat shape. In this way, the water drainage becomes worse, but the total height of the drainage adapter member 5 can be lowered accordingly, and the degree of freedom in designing can be increased.

  Moreover, in the Example of this invention, although comprised as a member integral with the bottom wall part 7 drainage adapter member 5 of the drainage adapter member 5, this invention is not limited to the said structure, It shows in FIG. You may comprise like the Example. In the embodiment of FIG. 6, the bottom wall portion 7 is configured separately from the drainage adapter member 5, and is instead formed integrally with the triangular packing 9 by an elastic material such as rubber, and is similar to the embodiment of FIG. It is configured to obtain an effect.
