Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage device for discharging drainage discharged from various equipments to a sewer pipe.

[0002]

2. Description of the Related Art Conventionally, waterproof pans for bathrooms, washing machines, etc.,
Or, for equipment such as washbasins and sinks that produce wastewater when used (hereinafter referred to as "drainage equipment"), the wastewater produced by the equipment is discharged to the sewage side.
A drainage system is used. Among the drainage devices, a drainage device called a drainage trap is well known which prevents odors and pests on the sewage side from flowing back.

Taking the drain trap as an example, the conventionally used drain traps shown in FIGS. 7 and 8 are each a trap body composed of a casing and a lid described below, a flange member, and a deodorant cylinder. It is composed of The casing has an opening at the top and a bottomed tubular water sealing portion, a water passage having a bottom wall in the middle of the side wall of the water sealing portion, and an outlet provided on the side surface of the water passage. The lid portion is joined to the opening of the casing and has an opening of a connection portion having a female screw that is screwed with a male screw of a flange member described later. The casing and the lid are watertightly joined to form a trap body. The flange member is provided with a drainage port inside the tubular shape, and is provided with a male screw threaded on the outer peripheral portion to be screwed into a female threaded portion of the connecting portion of the lid portion. The deodorant cylinder is a substantially cylindrical member that is open vertically, and is watertightly and detachably attached to the flange member on the upper side, and is disposed on the water sealing portion on the lower side.

A drain trap called a running trap is another drain trap having a structure different from that of the above-mentioned drain trap. The conventionally used running trap is shown in FIGS. 9 and 10 and described below.
The trap body includes a casing and a lid, and a flange member. The casing is provided with an opening at the top, a discharge port provided on the side surface, a rising wall rising from the bottom surface, a deodorant bowl portion formed by providing the rising wall, and a sealing provided in the deodorant bowl portion. And a partition part having an opened lower part for forming water. The casing and the lid are watertightly joined to form a trap body. The lid portion is water-tightly joined to the opening of the casing, and is formed by opening a connection portion having a female screw that is screwed with a male screw of a flange member described later. The flange member is provided with a drainage port inside the tubular shape, and is provided with a male screw threadedly engaged with the opening of the lid part on the outer peripheral portion.

The above-mentioned drain trap is attached to drain equipment such as a waterproof pan. As a method of attaching the drain trap to the waterproof pan, the drain pan is attached to the attaching hole provided in the waterproof pan so that the flange member and the connecting portion of the lid part sandwich the attaching hole via a watertight member. There is. When the water is drained to the waterproof pan or the like, the drainage is collected from the drain port of the flange member through the deodorant cylinder or the partition wall to the water sealing part, and the water overflowing from the upper end of the water sealing part flows through the water passage or the drainage flow path. It is discharged from the outlet. On the other hand, when odors, pests and the like flow back from the sewage side, it is possible to prevent them from entering by the water accumulated in the sealed portion.

In the drain trap having the above structure, the casing and the lid must be joined in a watertight manner by some method when the trap body is manufactured so that no water leaks when the drain trap is used. Examples of this joining method include a method of adhering with an adhesive if the casing and the lid are both made of synthetic resin, and a method of fusing and joining the resin with the energy of fine vibration by heat or ultrasonic waves. is there. Usually, as a method of joining with an adhesive,
Apply adhesive to one side of the casing or lid, attach both, and use a jig such as a clip or clamp so that the two do not move after attachment, or the adhesive remains fixed directly by the assembly operator's hand. Bonding is completed by curing until the resin hardens. Also, as a welding joining method, the members are fixed by a jig such as a clip or a clamp so that the members do not move or are directly fixed by an assembly operator's hand, and then joined by heat or ultrasonic waves.

Conventionally, as a method for joining the casing of the trap body and the lid, joining with the above-mentioned adhesive,
Although joining is performed by welding, there are problems as described below.

[0008]

A method of curing the adhesive until it hardens while it is directly fixed by the hand of an assembling worker so that the casing and the lid are not moved during joining with the adhesive, is extremely difficult during assembly and production. Not only was it troublesome, but it was also a labor cost and increased costs. Also,
If the casing and the lid are fixed by hand of the assembling worker so as to prevent the casing and the lid from moving during curing, and the curing is performed until the welded portion is hardened, the heat during welding is very dangerous for the worker. In addition, in order to prevent the casing and lid from moving during bonding or welding, the method of curing the adhesive until it hardens while the position is fixed using a jig such as a clip or clamp after joining, so that the casing can be fixed with the clip or clamp after joining. The process of fixing the lid part in position and removing the joint part after curing has increased, resulting in inefficiency. Furthermore, the number of clips and clamps to be assembled and produced must be prepared, which increases the cost. .

Further, in the above-described method of directly fixing by a worker's hand or curing the joining portion by using a clip or a clamp, the casing and the lid are tilted, so that the joining is erroneously incomplete. Is unlikely to be discovered,
After the construction of the drainage device has been completed and it has become extremely difficult to replace or repair the drainage device, it is possible to find a joint defect due to water leakage from the joint part during actual use. It was very difficult to implement a solution such as replacement of.

When joining the casing and the lid,
If there is a partition wall in the casing like the drain trap described in paragraph 0004 and the partition wall and the lid must be joined in a watertight manner, the opening of the casing is covered with the lid, so that the inside of the casing is covered. Since the joint part between the partition wall and the lid was not visible, it was necessary to perform a separate hydraulic test or the like to confirm whether or not the joint was securely made. The present invention was invented to solve the above problems.
