Next, in a case where water leakage occurs at the connection part of the upper end of the drain pipe 2 and the lower end of a joint pipe 8 and the connection part of the joint pipe 8 and a drain opening 14, leakage water allowed to flow down through the drain pipe 2 is received with the water receiver 5. Furthermore, leakage water is allowed to flow through the drain pipe 2 from the opening part 6, and prevented from dropping on a floor face or the like.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage pipe device connected to a drainage port of a hand washing ball such as a wash basin.

[0002]

2. Description of the Related Art Conventionally, as a drainage facility such as a washbasin, a drainage pipe is connected to a drainage port of a hand-washing ball. The connection between the drain of this hand washing ball and the upper end of the drain pipe is
The gap is sealed with packing or the like to prevent water leakage, and water leakage does not occur in normal use.

[0003]

However, there is a possibility that water leakage may occur at the connection between the drain port of the hand-washing ball and the upper end of the drain pipe due to faulty construction, distortion due to external force, corrosion of packing, etc. In such a case, conventionally, the leaked water flows along the drain pipe and flows down to the floor surface or the like.

The present invention has been made in view of the above circumstances, and provides a drain pipe device capable of preventing the leaked water from dropping onto the floor surface or the like even if water leaks at the upper end portion of the drain pipe. To do.

[0005]

A drain pipe device according to a first aspect of the present invention has a substantially vertical drain pipe which is connected to a drain port of a hand washing ball and hangs down from the drain pipe device. It is characterized in that a water receiver extending downward and outward is provided around the lower part, and an opening communicating with the drain pipe is formed at the bottom of the water receiver.

In this drainage pipe device, when water leakage occurs at the connection between the upper end of the drainage pipe and the drainage port of the hand-washing ball, the leaked water flowing down through the drainage pipe is received by the water receiver. It flows into the drain pipe through the opening of the drain pipe provided at the bottom of the water receiver. Therefore, it is possible to prevent the leaked water from falling to the floor surface or the like.

The drainage pipe according to claim 2 is the drainage pipe device according to claim 1, wherein the drainage pipe is an upper drainage pipe connected to a drainage port of a hand washing ball, and a lower end portion of the upper drainage pipe is an upper end. The upper and lower drainage pipes are provided at the upper end of the lower drainage pipe, while the lower drainage pipe is inserted and connected to the lower drainage pipe. It is characterized in that an opening communicating with the inside of the drain pipe is provided at a position corresponding to the bottom.

In this drainage pipe device, the drainage pipe is placed above and below the upper drainage pipe connected to the drainage hole of the hand washing ball and the lower drainage pipe in which the lower end of the upper drainage pipe is inserted and connected to the upper end. Divide and install a water receiver at the upper end of the lower drainage pipe,
On the other hand, the lower end of the upper drain pipe is provided with an opening communicating with the inside of the drain pipe, so that the shape of the drain pipe can be easily formed. That is, when molding the drain pipe using a resin or the like, the drain pipe is divided into upper and lower parts by the water receiving portion having a complicated shape as described above, thereby designing a molding die. Because it becomes easier.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing a drainage pipe device according to an embodiment of the present invention. FIG. 2 is a perspective view showing a usage state of the drainage pipe device according to the embodiment. FIG.
FIG. 3 is an enlarged view of a main part of FIG. 2.

As shown in the figure, in the drainage pipe apparatus according to the present embodiment, the handwashing ball 1 at the upper end of the drainage pipe 2 is attached to the drainage pipe 2 which is connected to the drainage port 14 of the washing ball 1 and hangs down.
A water receiver 5 that extends outward and upward is provided below the connection portion to the drainage pipe 2 at the bottom of the water receiver 5.
An opening 6 communicating with the inside is formed.

In this embodiment, the hand washing ball 1 is installed on the counter 18 as shown in FIGS.
The lower space of the hand washing ball 1 has a door on the front side and is used as a cabinet 18.
The drainage pipe 2 is connected at 18. The lower end of the drainage pipe 2 is connected to an S-type drainage trap 16 by a cap nut 15, and this S-type drainage trap 16 is further connected to a drainage pipe 17 leading to sewage.

In the drainage pipe device, the drainage pipe 2 is composed of an upper drainage pipe 4 connected to the drainage port 14 of the hand washing ball 1 and a lower drainage pipe in which the lower end portion of the upper drainage pipe 4 is inserted and connected to the upper end portion. The upper and lower parts are divided into three parts. At the upper end of the lower drainage pipe 3, a water receiver 5 is provided so as to extend outward and upward in a skirt shape, while the upper drainage pipe 4 is provided.
An opening 6 communicating with the inside and outside is formed at the lower end of the. The lower end of the upper drainage pipe 4 is adapted to be screwed into the upper end of the lower drainage pipe 3, and at this time, the opening 6
Is located at the bottom of the water receiver 5.

The upper end of the upper drainage pipe 4 is connected to the drainage port 14 of the hand washing ball 1 via a joint pipe 8. This joint pipe 8 has a drain plug inside, and its upper end is airtightly connected to the drain port 14 of the hand washing ball 1. That is, the drainage port 14 of the hand-washing ball 1 has a stepped portion in which the upper side of the inner peripheral portion is wide, while the joint pipe 8 has a thread formed on the outer peripheral surface and a packing 10 on the upper side. A nut 9 provided with a washer 11 is screwed, and a flange portion 13 that abuts on the stepped portion of the drain port 14 via a packing 12 is provided at the upper end.
