Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe joint for water supply / drainage related to a water supply device and a facility provided with drainage.

[0002]

2. Description of the Related Art Conventionally, water supply and drainage are provided independently of each other. Japanese Patent Application Laid-Open Nos. 1-222641 and 9-19534 describe conventional technologies for the purpose of saving construction.
3. As described in Japanese Patent Application Laid-Open No. 9-170249, there is a case where a pipe joint for water supply and drainage is provided in the same unit. It is a proposal only to arrange the water supply and the same. There is a problem in that a proposal for a reduction in construction required to promote the deployment of many devices having water supply and drainage has not been made.

[0003] In recent years, there has been an increasing number of retrofitting watering devices, such as washing machines, which are arbitrarily selected and installed by consumers, instead of watering devices installed as building equipment.

[0004]

The problem to be solved by the present invention is to facilitate the installation of a water supply pipe, which is indispensable for the installation of drainage, and to expand not only for water supply equipment designed by building equipment in advance, but also for the future. The present invention proposes an inexpensive, small-sized piping joint that facilitates the development of equipment for using retrofitted water that is arbitrarily selected by the user and that has at least the same water supply connection and drainage connection that does not require much installation space.

[0005]

SUMMARY OF THE INVENTION In some home appliances utilizing water, such as a washing machine, a drain trap provided for ensuring hygiene is not provided. In addition, when a device equipped with a drain trap is installed, two or more drain traps are formed on the same drain path, so that the trap is broken due to the siphon phenomenon and the normal trap function cannot be performed,
It has hygiene problems such as the blocked air between the two rots. To solve these problems,
It is desirable that drainage traps, which are essential for drainage, be provided at drainage joints, and that basic specifications be clarified. The drain trap section is configured as an independent unit in consideration of a special drainage system in the future and cleanability.

[0006] The drain pipe has a large diameter unlike electric wiring and the like, and it is not preferable to pass the pipe through a wall surface that affects the living room space. Generally, it is installed fixed to the outer wall like a rainwater pipe by penetrating the wall. As a concrete installation case, such examples of installation with air conditioners such as coolers are increasing, but from now on, water supply, hot water supply and drainage piping will be placed on the floor where layout can be changed and maintenance can be performed without damaging the appearance of the house Then, it is considered desirable to fix the pipe joint to the floor. Since many things such as washing machines, furniture and storage cases are placed on the floor, extremely small pipe joints are required.

[0007] In order to open an opening for fixing a pipe on the floor surface, it is considered that a circular shape capable of drilling is desirable in order to shorten the working time of drilling. In addition, the drainage pipe may have a circular shape, and the floor-mounted drainage joint has a circular bell-shaped or bottle-shaped drainage pipe that is fixed to the equipment drainage pipe and the equipment skeleton. And a water supply joint was provided separately. In this,
The floor had to be drilled in at least two places, and was not rational in terms of installation space and construction. Therefore, as in the scope of this patent, a water supply / hot water supply and drainage pipe joint unit are provided in the same circular opening, and the shape of the drainage trap is not a simple cylinder,
We propose an inexpensive, compact, water-saving plumbing pipe fitting that has a curved shape that matches the shape of the inner surface of the box that houses the pipe fitting unit, that is inexpensive, compact, and requires less construction time.

[0008] Since last year, regulations have been deregulated, the system of designated construction shops that have been managed locally has been abolished, and consumers can freely select construction contractors. Therefore, there is a possibility that a mismatch may occur between the hot water supply / water supply / drainage pipe, which is one of the building structural members, and the water utilization equipment connected thereto. Furthermore, if products such as washing machines that consumers themselves may connect and install expand, this may become a big problem. In particular, in the case of home appliances using water such as washing machines, emphasis has been placed on convenience and cost reduction, and the importance of water supply and drainage facilities as conventional sanitary facilities is fading. Therefore, this time, we proposed a drain trap that is indispensable as a sanitary facility, and if possible, standardized the installation of a drain trap for drain joints, and proposed a use that can be changed in the future as the equipment evolves.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Piping joints necessary for installation of equipment using water supply, hot water supply and drainage are formed in units, and housed in a circular box that is easy to install. A drain trap was provided at the joint of the drain pipe in consideration of the installation of home appliances using water such as a washing machine without a drain trap.

[0010] A cover member is provided at the upper end of the pipe joint storage box in order to improve the appearance of the pipe joint storage box and prevent foreign matter such as dust from entering the pipe joint storage box.

Consumers have various demands and are trying to select an appliance according to their own life. Due to this consumer-led flow, deregulation has progressed, and water supply and drainage have been connected by the hands of construction companies other than those approved by the Waterworks Bureau, while being directly connected to water supplies such as fully automatic washing machines and dishwashers. I have. In existing home appliances using water such as a washing machine, a drain trap, which is an essential condition in sanitary facilities, is not provided on the appliance side, and a drain trap is provided on a drain pipe joint side of a building frame. However, since there is a provision in a bathroom vanity or the like that a drain trap is provided on the appliance side specified for sanitary facilities, a drain trap is unnecessary on the piping facility side. Equipped with this drain trap as standard and provided with a pipe joint that allows the drain trap to be easily attached and detached depending on the presence or absence of the drain trap on the terminal equipment, confusion in selecting equipment can be eliminated. In the future, by providing a drain trap that plays a role of a safety device in a sanitary facility, the specifications of the connected appliance will be simplified, and a product that can be easily understood by consumers will be developed.

It is difficult to safely supply and drain water. Therefore, by associating the water supply and the drainage with each other and configuring the water supply and the drainage in one unit, it is possible to improve safety. Of particular importance is a drain trap, which is a safety device for drainage equipment. The drainage capacity largely depends on the flow resistance of the drain trap. Therefore, if the water supply conditions are confirmed on the premise of the discharge capacity of the drain trap, even if the drain trap is removed, the drain resistance is reduced, and there is no excess supply. If there is a drainage problem on the equipment side, it is the responsibility of the manufacturer to supply the equipment. In this way, by providing a drain trap as a standard on the equipment side and adjusting the water supply conditions, the responsible place of the problem is clarified, and the consumers can select the equipment and equipment with confidence.

Since the water supply and drainage pipes are one-touch jointed, they can be provided at a low construction cost without requiring advanced technology. In addition, after construction, water leakage accidents due to loose pipe connections due to aging during use are also prevented, so that anyone can install a water supply device with confidence in the future. Therefore, various water use equipment can be used without limiting the use. For example, a vanity table, a shower capsule, an ornamental water tank, a water bed, and the like can be installed in a bedroom.

Since the water use equipment can be easily installed, the temporary installation is also easy. Therefore, a kitchen wagon equipped with a hot water supply pot by installing a water use device in a nursing care toilet, hand wash, bathing equipment, a movable wagon, and connecting it with a piping joint unit with a flexible connecting hose. , Remarkable improvement of life is achieved.
