Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain pipe odor stop trap for preventing odor from leaking into a room from a drain pipe provided in each door of a high-rise house, for example.

[0002]

2. Description of the Related Art In a high-rise house, etc., a water pipe for discharging domestic waste water from a washing machine or the like is provided in each house. It is necessary to prevent odor from rising from the drain pipe to the room. Is an issue.

In view of the above, various odor control traps for preventing odor from leaking from a drain pipe have been provided, and a drum trap is generally widely used as the odor control trap. As shown in FIG. 6, this drum trap has a bowl-shaped trap body 1 having an inflow opening 1A into which a drain hose is inserted at the top and a pipe insertion port 1B at the bottom, and a plurality of drains on the outer peripheral surface. The bell 2 is roughly configured from a bell 2 having an inflow hole 2A, and the bell 2 is provided in the trap body 1 so as to cover the drain pipe 3. The drum trap is inserted and supported in a state of being locked in an insertion hole 5 provided in the floor 4.

In the drum trap having the above structure, when the drainage A flows into the trap body 1 from a washing machine or the like, the drainage A does not flow directly into the drainage pipe 3 because of the obstruction of the bell 2, but the drainage inflow hole 2A Through the bell 2. The drainage A that has flowed into the bell 2 is discharged from the drainage pipe 3 when it exceeds the protruding height of the drainage pipe 3, but below that, it is retained in the trap body 1 and odors are prevented from leaking from the drainage pipe 3. To prevent.

[0005]

However, the above-mentioned conventional drum trap has the following disadvantages. That is,
Dust is likely to accumulate at the bottom of the trap body 1, and when the amount of dust increases, the amount of staying wastewater decreases, so that the staying wastewater evaporates quickly. When the accumulated waste water evaporates, the trap effect is lost and it becomes impossible to prevent the leakage of odor. Further, the drainage method is an overflow type, and the drainage A that has flowed into the trap body 1 does not immediately flow into the drain pipe 3, so that the drainage efficiency is poor. In particular, when the amount of drainage is large, such as in a fully automatic washing machine, a situation where drainage is impossible may occur.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and the problem to be solved is to prevent dust from accumulating in the trap body and reliably prevent odor from leaking to the outside. It is an object of the present invention to provide an odor control trap for drainage pipes that can be performed and has high drainage efficiency.

Means for Solving the Problems According to the means of the present invention configured to solve the above problems, an annular trap support body having an inflow opening for inflowing drainage, and an upper end side A flexible trap cylinder attached to and suspended from the peripheral surface of the trap support, and a pair of opening / closing openings made of magnetic rubber attached to the peripheral surface of the lower end of the trap cylinder. Consists of.

The upper end of the trap cylinder may be replaceably fastened to the peripheral surface of the trap support by a stop ring.

[0009]

In the drain pipe odor control trap constructed according to the present invention, the pair of opening / closing ports are magnetically attached to each other by the magnetic force thereof when the drainage is not flowing, and the lower end side of the trap cylinder is closed. ing.

When the drainage flows in, the pair of opening / closing portions are kept magnetically attached at the initial stage, but when the drainage flowing into the trap cylinder increases and reaches a predetermined amount, the weight of the accumulated drainage is resisted. Without being separated from each other, the trap cylinder is in an open state, and the inflowing waste water is straightly dropped from the opening and flows out. Also, when the amount of inflowing drainage decreases to a predetermined amount or less, the magnetic force acting on the pair of opening / closing ports is magnetically attached against the weight of the accumulated drainage, and the opening / closing port again closes the trap cylinder. become. Then, the opening / closing portion repeats the closed state and the open state in accordance with the amount of staying of the drainage flowing into the trap cylinder.

The trap cylinder can be replaced with a new trap cylinder by removing the retaining ring and removing it from the trap support.

Reference numeral 12 denotes a donut-shaped hose support,
The hose support 12 is formed with an annular groove 12A on the outer peripheral surface, which fits into the inner protrusion 11D of the trap support 11,
The inner opening is the drain hose insertion port 12B.

Reference numeral 13 denotes a cylindrical trap cylinder. The trap tube body 13 is made of a rubber material having a thin thickness of about 0.3 mm, and is formed into a tube shape having upper and lower ends 13A and 13B opened. On the upper end 13A side of the trap cylinder 13, a pair of metal or rubber stop rings 14, 14 are formed on the outer peripheral surface of the body 11B of the trap support 11 to engage the respective locking grooves 11E.
Is fastened in a state of being engaged with.

Reference numerals 15 and 15 denote a pair of opening / closing ports made of plate-shaped magnetic rubber. The pair of opening / closing openings 15 and 15 are attached so as to face the outer peripheral surface of the trap tube body 13 on the lower end 13B side, and both ends 15A and 15A of the opening / closing openings 15 and 15 are a pair of U-shaped stainless steel. Steel caulking tool 16,
It is sandwiched by 16.

The odor-preventing trap of the present embodiment having the above-mentioned structure is installed in a state where the upper end is inserted into a drain pipe which is airtightly connected to the lower surface of the floor 4, or when the trap is attached to the upper end of the drain pipe. It is hung from the floor 4 in a state where it is liquid-tightly connected and the upper end is inserted into a housing cylinder airtightly connected to the lower surface of the floor 4.

Next, the operation of the above embodiment will be described. 1 to 3 show a state in which the drainage A does not flow into the trap cylinder. In a state where the wastewater A is not flowing in, the pair of opening / closing ports 15, 15 made of magnetic rubber are magnetically attached to each other via the trap cylinder 13 due to its magnetic force, and the lower end 13B side of the trap cylinder 13 is closed. It is in a state. And the trap cylinder 13 is about 0.3 mm
Since it is made of a thin and flexible rubber material, the lower end 13B side of the trap cylinder 13 sandwiched by the pair of opening / closing openings 15, 15 is in a sufficiently crimped state. A part of the drainage A remains in the cylindrical body 13.

On the other hand, when the drainage A flows into the trap tube body 13, the pair of opening / closing openings 15, 15 are kept magnetically attached in the initial stage, but the amount of the drainage A flowing into the trap tube body 13 is retained. 4 increases and reaches a predetermined amount, as shown in FIG. 4, the weight of the accumulated waste water cannot be resisted and they are separated from each other, and the lower end 13B side of the trap cylinder 13 is opened. As a result,
The drainage A that has flowed into the trap tube body 13 straightly drops from the opening on the lower end 13B side and flows out.

Then, when the amount of the inflowing wastewater A decreases and becomes less than a predetermined amount, the magnetic force acting on the opening / closing ports 15, 15 resists the weight of the staying wastewater and is again magnetized through the trap cylinder 13. The lower end 13B side of the trap cylinder 13 is closed. In addition, the pair of opening / closing ports 15, 15A on both sides of the opening / closing section 15,
Since 15A is sandwiched by the caulking tools 16 and 16 in an abutting state, the opening / closing ports 15 and 15 can be re-magnetized smoothly when the accumulated drainage is less than a predetermined amount. Thus, the opening / closing sections 15 and 15 repeat the closed state and the open state depending on the amount of the waste water A flowing into the trap tube body 13.

Although the trap cylinder 13 is made of a rubber material in this embodiment, it may be made of a synthetic resin film having flexibility and strength.

Although the present invention has been described in detail with reference to one embodiment, the present invention is not limited to the above embodiment, and various changes or modifications can be made within the scope of the present invention. is there.

[0023]

According to the odor control trap for a drain pipe constructed according to the present invention, a pair of opening and closing ports made of magnetic rubber are magnetically attached to each other by the magnetic force in a state where no drainage is flowing in, and the trap cylinder body The lower end side is in a closed state, and odor leakage from the drainage pipe can be reliably prevented by the trap effect of the accumulated drainage.

When the drainage flows into the trap cylinder and the accumulated drainage in the trap cylinder reaches a predetermined amount, the pair of opening / closing ports cannot withstand the weight of the accumulated drainage and are apart from each other to be in an open state, and the inflowing drainage is trap trap Since it falls straight down from the lower end of the body and flows out, the water can be drained very efficiently.

Further, since the trap cylinder extends linearly downward, dust is not accumulated inside the trap cylinder, which requires no maintenance and is very convenient to handle.

The trap cylinder can be replaced with a new trap cylinder by constructing the trap cylinder so as to be replaceably fastened to the trap support.
