JPH07305392A - Foreign matter detecting device for toilet flush system - Google Patents

Abstract

PURPOSE:To pass an overcurrent when some foreign matter reaches a pump so as to detect the foreign matter and to stop the feeding of flush water to remove the foreign matter by attaching a cutter-equipped pump freely removably to the discharge opening of the toilet, and providing a control circuit which couples a feed water solenoid valve and a lamp-equipped pump to a feed water pipe. CONSTITUTION:A flush pipe 3 is connected to the discharge opening 2b of a toilet 2 having a trap 2a on a floor 1. A cutter-equipped pump 4 is freely removably provided in this pipeline. Next, a control circuit 10 which couples together the cutter-equipped pump 4, a power source 5, a feed water solenoid valve 8 provided in a feed water pipe 7 leading to a toilet flushing feed water tank 6, and a lam-equipped buzzer 9, is provided. An overcurrent is passed if any foreign matter flowing out of the toilet 2 reaches the pump 4. Then the control circuit 10 operates the solenoid valve 8 to close the valve. Therefore, even if any foreign matter is flushed by mistake, it is detected quickly and easily and the closure of the flush pipe 3 or the like can be undone.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foreign matter detection device for a toilet drainage system, and in particular, when foreign matter is accidentally flushed into a toilet bowl provided in a public toilet,
The present invention relates to a device capable of detecting and removing the foreign matter.

[0002]

2. Description of the Related Art A public toilet, such as a restaurant,
Foreign bodies are often accidentally or intentionally flushed into a toilet bowl provided in a toilet provided in a hospital, a station, a multi-story building, or the like. Then, the foreign matter may be clogged in the trap of the toilet bowl or the bent portion of the drainage pipe, and the bearing may come to the entire drainage system. However, the equipment of the drainage system of these toilets is designed to have a structure capable of quickly flowing sewage, and is a device capable of detecting and removing foreign matter. Is not provided because it goes against the performance that allows swift water to flow quickly.

[0003]

When foreign matter or the like accidentally flowed is blocked in the trap of the toilet bowl or the bent portion of the drain pipe of the toilet as described above, it is necessary to find the blocked portion. take time. Also, in public toilets, many places are equipped with multiple toilet bowls and the amount of drainage is large, and if foreign matter is clogged in the trap of the toilet bowl or its drain pipe, sewage collects, so restoration work is also required. It's not easy, and it's often a problem because craftsmen hate the work.

The present invention is intended to solve the problem that foreign matter or the like is clogged in the trap of a toilet bowl provided in a public toilet and its drain pipe is blocked, and its purpose is to solve the problem. Provided is a foreign matter detection device for a toilet drainage system, which is capable of quickly detecting a foreign matter even if a foreign matter is flown into the toilet bowl, and stopping the water supply for cleaning at the same time as detecting the foreign matter to remove the foreign matter. It is a thing.

[0005]

Means for Solving the Problems As a result of intensive studies on the solution of the above problems, the present inventor has freely attached or detached a pump with a cutter to or from the drain of a toilet bowl or the outlet of a toilet bowl without a trap. Attention was paid to a device that was attached to the device and was capable of detecting foreign matter by sensing an overcurrent when foreign matter was applied to the pump and detecting the current change.

As a means for achieving the above object, the present invention attaches a pump with a cutter to a drainage pipe of a toilet bowl in a freely attachable and detachable manner, and a solenoid valve for water supply provided on the pump with the cutter and a water supply pipe to a water tank for cleaning a toilet bowl. And a buzzer with a lamp are provided with a control circuit, and a foreign matter detection device for a toilet drainage system, and a pump with a cutter are detachably attached to the outlet of a toilet without a trap, A drainage pipe is provided with a trap, and a control circuit for connecting the pump with a cutter and the solenoid valve for supplying water to the water supply pipe to the water tank for toilet cleaning and a buzzer with a lamp are provided. This is a foreign matter detection device.

The urinal in the foreign matter detecting device for the toilet drainage system of the present invention may be any one of a Western style urinal, a Japanese style urinal, and a built-in Western urinal, and an existing Western or Japanese style urinal may be used. Can also be attached. And
In the case of a toilet bowl having a normal trap, the foreign matter detecting device according to the present invention is preferably detachably attached with a cutter pump to a drain pipe connected to a discharge port, but is limited to only this one place. Instead, drainage pipes such as toilets in multi-story buildings can be attached to drainage horizontal pipes on each floor. In addition, in the case of a toilet bowl without a trap, a pump with a cutter is freely attached to and detached from the outlet of the toilet bowl.

Next, according to the present invention, a pump with a cutter that is detachably attached to a drain pipe or a discharge port of a toilet bowl, a water supply solenoid valve provided in a water supply pipe to a water tank for cleaning a toilet bowl, and a buzzer with a lamp are connected. It is equipped with a control circuit, and when foreign matter is strongly applied to the cutter pump, an overcurrent flows, and this current change causes the circuit to act on the solenoid valve to close the valve and stop water supply. So, by removing the pump with a cutter,
By removing the foreign matter applied to the pump, the blockage of the drain pipe and the like can be released.

The pump with a cutter used in the present invention is used for drainage of a sewage tank, for a sewage treatment plant, and the like, and there are those equipped with various cutter mechanisms according to the application, and there are large foreign matters and fibrous substances. Foreign substances can also be discharged. And if you don't need to chop too much,
It may be simply a blade. In the present invention, in addition to the method of detachably attaching the pump with a cutter to the outlet of the toilet bowl, this pump with a cutter can be freely attached to and detached from the drain pipe connected to the outlet of the toilet bowl or the drainage horizontal pipe on each floor. This pump can be used to pump wastewater and waste even if the drainage horizontal pipe can not be sloped. Further, in the present invention, in order to receive water leakage when the pump is attached and detached, it is preferable to provide a saucer under the pump.

[0010]

According to the present invention, even if foreign matter or the like is poured into the toilet bowl,
The foreign matter can be detected quickly, the water supply for cleaning is stopped at the same time when the foreign matter is detected, and the foreign matter can be removed to release the blockage of the drain pipe or the like. Further, when a foreign substance is clogged in the drain pipe or the like, only the toilet bowl associated with the detection device or the clogged floor thereof cannot be drained until the foreign substance is removed.
