Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a trap body having a wastewater inflow port and a wastewater discharge port, and a watertight water storage space provided therein. The inflow port and the discharge port are connected to the water storage space. The present invention relates to a waste water trap device in which a communication part is formed below the discharge port.

[0002]

2. Description of the Related Art Conventionally, as this type of waste water trap device, there is a device that simply stores water in a water storage space, and a gas that causes an offensive odor flows back from a downstream pipe to an upstream water use portion. Only the route is blocked by the water storage space so as to prevent a bad odor in the water use part.

[0003]

However, according to such a waste water trap device, although bad odor can be prevented, various bacteria are easily proliferated in the water in the water storage space, which is particularly high in hospitals and the like. In places where hygiene control is required, there is a possibility that pathogenic bacteria and pollutants may lead to nosocomial infections such as MRSA and Pseudomonas aeruginosa, which is not preferable.

Therefore, an object of the present invention is to provide a waste water trap device which prevents a bad odor in a water use part and prevents propagation of various bacteria in the water storage space.

[0005]

Therefore, a feature of the present invention resides in that a supply device for supplying ozone or active oxygen ions is provided in the water storage space, and the trap body is provided with the water storage space. It is also possible to provide a circulation flow path for taking out the waste water and blowing it into the water storage space, a circulation pump for circulating the waste water in the circulation flow path, and connecting the supply device to the circulation flow path. The blow port of the circulation flow path to the water storage space is provided in the lower portion of the trap body, and the blow port is preferably arranged eccentrically with respect to the center of the trap body in a plan view, The action and effect are as follows.

[0006]

[Function] Ozone is generally known as a strong oxidant, and is known to be used for sterilization, deodorization, bleaching, etc. On the other hand, active oxygen ions have a strong oxidizing property such as ozone. Although not shown, it exhibits deodorizing and sterilizing effects, and is known to be used for refrigerator sterilization and the like. That is, since a supply device for supplying ozone or active oxygen ions is provided in the water storage space, by supplying ozone or active oxygen ions into the water storage space, various bacteria that live in the waste water retained in the water storage space are provided. It was possible to provide a wastewater trap device which can sterilize and remove the above-mentioned substances and which has an effect of preventing the propagation of various bacteria in addition to the effect of preventing the conventional bad odor. Further, if the supply device is a supply device for supplying ozone, it is possible to decompose and remove organic components contained in water in the water storage space, and an environment in which bacteria are less likely to propagate in the water storage space, It is possible to create an environment in which there are few organic substances that cause a bad odor. Further, if the supply device supplies active oxygen ions, the quality of the waste water discharged downstream from the water storage space can be made safer.

Further, a circulation passage for taking out the waste water from the water storage space and blowing it into the water storage space is provided, and a circulation pump for circulating the waste water is provided in the circulation passage, and the supply device is provided with the circulation flow. If it is provided in the passage, ozone or active oxygen ions can be efficiently supplied into the water storage space, and it is easy to uniformly disinfect the entire wastewater in the water storage space.

Further, a blow-in port of the circulation flow path to the water storage space is provided in the lower part of the trap body,
If the blow-in port is provided eccentrically with respect to the center of the trap body in a plan view, a swirl flow is generated in the water storage space, and the sediment deposited at the bottom of the water storage space is swirled. With this, it is possible to stir and to uniformly supply ozone or active oxygen ions to the waste water accumulated in the trap.

[0009]

EFFECTS OF THE INVENTION Therefore, even if water stays in the wastewater for a long time, it is difficult for bacteria to propagate in the wastewater in the wastewater trap. Therefore, hygiene control is performed even in a use such as a hospital requiring a high degree of aseptic condition. It became easier.

Further, when a swirl flow is generated in the water storage space, solid substances such as organic substances precipitated in the water storage space are wound up in the water by the swirl flow, so that ozone or active oxygen ions are more likely to be generated. It can be disintegrated evenly at the same time as sterilization, making it easier to create an environment in which various bacteria are less likely to occur.
