Description

The present invention relates to a drainage device used for a drain outlet provided with a tank body, such as a wash basin or a sink.

Conventionally, as shown in FIG. 7, for example, a drain trap as a drain device used in a sink is well known.
This conventional drainage device is attached to a sink of a sink as a tank body.
Moreover, the drain trap as a drainage device is comprised from the main-body part, opening part, sealing part, discharge port, and attachment member which are described below.
The main body part is a member that discharges the drainage of the sink into the sewage, and includes a flange part that protrudes upward in the upward direction, and a male screw for screwing a mounting member described later on the outer peripheral surface. The Moreover, it comprises the opening part, water seal part, discharge port, and attachment member which will be described later.
The opening is an opening that is configured upstream of the main body and allows the drainage from the sink to flow into the main body.
The sealing portion is integrally formed below the main body portion. Moreover, the said water-sealing part is comprised from the water-sealing upper limit wall comprised so that the bottom face protruded upwards, and the water-sealing lower limit wall drooping downward from upper direction. The sealed water is constituted by a sealed water lower limit wall and a sealed water upper limit wall, and has a function of preventing odors and pests from sewage from flowing backward indoors by always storing drainage.
The discharge port is configured at a substantially right angle with respect to the flange portion of the main body, and is configured in the side surface direction.
The attachment member is a ring-shaped member, and an internal thread is formed on the inner surface, and is screwed onto the male thread of the main body.

In addition, the conventional drainage device and the sink are attached by locking the flange portion of the main body portion to the attachment opening opened in the sink via the watertight packing.
Then, the attachment member is inserted from below the main body portion toward the sink, and the male screw of the main body portion and the female screw of the attachment member are screwed together. Then, the attachment of the sink is sandwiched from above and below by the flange portion of the main body and the attachment member, and the attachment is completed.
Thereafter, the discharge port and the drain pipe are connected to complete the construction.

Moreover, the flow of the drainage of the conventional drainage device is as follows.
The drainage from the sink flows into the main body from the opening of the main body, reaches the sealed water in the main body, and is discharged from the discharge port via the sealed water lower limit wall and the sealed water upper limit wall. Drainage drained from the discharge port is drained into sewage through a drain pipe.

By the way, the drainage that passes through the drainage device is the water after use by the user of the drainage device, so it contains hair, scales, cocoons, leftovers, garbage, mud, detergent waste and other filth. In many cases, these substances adhere to the inner wall of the pipe and accumulate during long-term use of the drainage device, which may block the drain trap and drain pipe, eliminating this blockage. This is one of the issues to be solved regarding drainage devices and drainage pipes.

As a solution to the above-mentioned problems, a metal wire wound in a coil shape is inserted from the drainage port, and it collides with the clogged material at the blockage location to break it up. A high-pressure cleaning method is known in which a hose pipe having a stub is inserted, high-pressure water discharge is discharged from the hose pipe to the clogging material at the blockage site, and the blockage is eliminated.
However, in the case of drainage traps and drainage pipes that are not particularly prepared for blockage of the pipe, when the cantool method or high-pressure washing method is performed by operating from the drainage port, the cantilever method from the drainage port to the trap upstream pipe part Metal wires and high-pressure cleaning hose pipes can be inserted, but the metal wires and hose pipes cannot be bent in the complicated trap area caused by bending or the arrangement of members for forming the sealing part, Since the metal wire and the hose pipe cannot pass, the can tool method and the high pressure washing method cannot be performed downstream from the discharge port of the drain trap. For this reason, the clogging of the pipe downstream of the trap outlet, particularly when the clogging material is accumulated in the drain pipe, cannot be solved unless the drain pipe and the drain trap are disassembled and cleaned.
In particular, in the drainage device of the above-described conventional example, since the sealing part is integrally formed with the main body part, the sealing upper limit wall and the sealing lower limit wall of the sealing part are in the way, and high pressure cleaning and cantool hoses The pipe could not reach the drain pipe.
In addition, the can tool and the high-pressure washing pipe are inserted through the opening of the drainage device, and the inside of the bent drainage pipe is operated from the opening side while operating the hose pipe. The inner peripheral surface may be damaged by friction with the hose pipe itself such as a can tool.

Japanese Patent Publication No. 7-18186 (FIG. 2)

The above drainage device has the following problems.
1. Since the main body portion and the sealed water portion are integrally formed, the inside of the sealed water portion cannot be easily cleaned, and the cleanability is very poor.
2. Since the sealing part is configured at the bottom of the main body, the sealing part is exposed from the upper part of the opening, and the sealing part that is part of the drainage is exposed to the outside. Looks bad.
3. Since the main body portion and the sealed water portion are integrally formed, the sealed water portion of the drain trap cannot obstruct the hose tube such as the can tool or the high pressure cleaning to reach the drain tube.

4). The main body and the tank body are attached by screwing, so that the person fixing the main body from the upper side of the tank body during construction, the attachment member from the lower side of the tank body to the main body part Two workers, who are rotated and screwed together, were required, and it took a lot of work to construct.
5. In addition, even if the construction with the tank body is completed, the screw thread may be loose due to the variation of the installer, and in such a case, water leaks from between the tank body and the flange part of the main body part. Damage may occur. In order to prevent such a situation, torque management was required at the time of construction.
6). Also, because the outlet is configured to be almost right-angled when viewed from the side, hose pipes such as can tools and high-pressure cleaning can damage the inner peripheral surface of the outlet when trying to reach the drain pipe. In the worst case, the drainage pipe may be damaged and water leakage may occur.
7). In addition, conventional drainage devices are often made of synthetic resin for the cost of the product or due to shape problems, but if the main body is made of synthetic resin, slime due to various bacteria will occur. However, since the tank body is made of a metal material such as stainless steel, if only the drainage device is made of synthetic resin, there is a problem that the tank body is not harmonized and the appearance is very poor. .
