Description

[Detailed explanation of the invention] (1) Industrial application field This invention relates to deodorizing exhaust air from flush toilets.

(2) Conventional technology In the conventional technology, a deodorizing tube was connected and flowed in the middle of a wastewater flow pipe between the systank and the toilet bowl, and a ventilation fan was provided at the end of the deodorizing tube.

(3) Problems to be solved by the invention The conventional technology in which a deodorizing pipe is connected between the system tank and the toilet bowl, and a ventilation fan is installed at the tip of the deodorizing pipe, has a problem in deodorizing the toilet bowl if the ventilation fan is weak. If sufficient effectiveness is not achieved, and if a deodorizing forced exhaust system with a small air volume and high pressure exhaust type is installed for deodorization, the fluid wastewater that falls from the systank will be drawn into the deodorizing pipe from the branch, which will affect the water washing function. There was a risk that it would cause trouble.

(4) Means to solve the problem In order to solve this problem, a root is attached to the branching part of the drainage flow pipe and the exhaust pipe, and by rotating based on the root, the drainage flow pipe and the exhaust pipe are separated. A valve that can close either side is installed, and a spring attached to the branch part is used to block the drain flow pipe at all times, and the exhaust pipe is blocked only when the drain water is allowed to fall from the system tank. The purpose is to centrally deodorize the large number of toilet bowl locations using a powerful forced deodorizing ventilation system installed higher than each cistern.

(5) Effect Since this device has the above structure, when water does not flow from the system tank to the toilet bowl, water flows from the toilet bowl through a part of the drainage flow pipe and enters the exhaust pipe from the branch part.
It enters the deodorizing ventilation main pipe and reaches the deodorizing forced exhaust system, and when water is flowed from the system tank, the pressure of the water causes the valve to rotate against the force of the spring, blocking the entrance of the exhaust branch pipe, and flowing into the drainage flow pipe. The flowing water does not flow into the exhaust branch pipe, but instead flows into the toilet bowl. Meanwhile, the exhaust branch pipe inlet is blocked by the rotating valve, and water does not enter the exhaust pipe.

Next, when the flow of water from the cistank is stopped, the valve is rotated by the force of the spring to its original state, and the cistank again blocks the water pipe inlet at the branch part of the drainage flow pipe, so the odor from the toilet bowl is removed from the branch part. The system runs through the previous drainage flow pipe and the exhaust branch pipe from the branch to the forced deodorizing ventilation system, and is intended to concentrate the odors from many toilet bowls and eliminate them all at once.

(6) Example An exhaust branch pipe 5 is provided from the branch part 4 of the wastewater flow pipe 3 that connects the system tank 1 and the toilet bowl 2, and the exhaust branch pipe 5 is connected to the deodorizing ventilation main pipe 6 that passes through each floor. 6 is connected to a forced deodorizing ventilation system 7 provided on the roof. Further, an air volume adjusting damper 8 is provided near the exhaust branch pipe 5 connected to the deodorizing ventilation main pipe 6. A leaf spring 11 is wound around the valve shaft 10 which is supported on both sides by the enlarged parallel side wall part 9 in the branching part 4, a leaf spring stopper 12 is fixed to the pipe wall, and a synthetic resin valve is attached to the leaf spring 11. 13
is firmly attached.

When water is not flowing from the system tank 1 toward the toilet bowl 2, the leaf spring 11 closes the valve 13 at the top of the drain flow pipe 3 at the branch part 4, so that the odor from the toilet bowl is connected to the toilet bowl 2. However, since the valve 13 closes the upper drainage flow pipe 3 from the branch part 4, it flows into the exhaust branch pipe 5, enters the deodorizing ventilation main pipe 6, and reaches the forced deodorizing ventilation system 7 on the roof.
It is deodorized and released into the air.

When water flows from the system tank 1, the valve 13 rotates against the force of the leaf spring 11 due to the flow of water, and the inlet to the exhaust branch pipe 5 is blocked within the branch part 4, so that water flows into the toilet bowl 2. .

Next, if you stop the water from flowing out from cistank 1,
The force of the leaf spring 11 acts, and the valve 13 rotates again to close the upper part of the drain flow pipe 3 at the branch part 4, and the odor from the toilet bowl 2 is discharged through the drain flow pipe 3 again to the exhaust branch pipe 5.
It enters the deodorizing ventilation main pipe 6 that passes through each floor, and then enters the forced deodorizing ventilation system 7 on the rooftop.

Therefore, the odor from the toilet bowl 2 is always absorbed by the forced deodorizing ventilation device 7 except when water is being flushed from the systank 1, and there is no longer any odor in the room. If the suction from the exhaust branch pipe 5 is too strong and causes a problem in the rotation of the valve 13 when water is flowing from the systank 1, the air volume can be adjusted using the air volume adjustment damper 8.

(7) Effects According to this invention, the odor inside the toilet bowl is always sucked into the forced deodorizing ventilation system, and as long as the water from the cistank is not dropped, the odors can be ventilated regardless of the flushing water, and the odors can be ventilated from the cistank. Ventilation of odors is stopped only when water is flushed into the toilet bowl, and there is a valve at the junction between the drainage flow pipe and the exhaust branch pipe to close the mouth of the drainage flow pipe or the exhaust branch pipe. Normally, the drainage flow from the system tank is Since the pipe opening is blocked, deodorizing exhaust is carried out smoothly, and when cleaning water falls from the system tank, the exhaust branch pipe opening at the branch part is blocked, so that part of the cleaning water does not flow into the exhaust branch pipe.
The toilet bowl can be cleaned, and odors are completely eliminated from entering the room.
