JP2003082733A - Drain trap for bacterial interrupting floor - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve such a problem with a conventional drain trap that, in order to prevent sealing water from being lost or kill miscellaneous bacteria or micro organism growing in trap sealing water, water must be fed manually and sewage must be treated in a drain treating facility or drug must be filled directly into the sealing water for sterilization. SOLUTION: A commercial germicidal lamp 6 is installed in the sealing water of a drain trap to kill miscellaneous bacteria or micro organism growing in the sealing water, and optical catalyst is thermally sprayed or baked on the inner surface of the trap to oxidize and reduce organic substances in the trap by utilizing ultraviolet ray produced by the germicidal lamp 6 so as to decompose into water and oxides in order to spontaneously decomposing contamination for deodorizing effect or decompose the cell membranes of bacteria for sterilization. Hot water is intermittently filled from a hot water device into a trap body 3 through a hot water filling port 5 to kill the miscellaneous bacteria or micro organism growing in the sealing water and prevent odor from returning into a room due to losses of the sealing water in the trap. These operations are automatically controlled by a control panel.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention aims at killing germs and microorganisms in the water of a drain trap body which flows in from an upper surface and drains to a lower portion. The present invention relates to a detachable floor drain trap capable of blocking bacteria. 2. Description of the Related Art In order to kill bacteria and microorganisms that grow in trap water, which is a drawback of conventional wastewater traps, water must be supplied manually and wastewater must be treated in wastewater treatment facilities. Alternatively, it was to inject a drug and sterilize it. However, this method requires a manual operation of supplying water to the drain trap or an operation of injecting chemicals, and sometimes forgets to perform the periodic operation. [0004] In order to reduce or stop the operation of water supply and chemical injection, the present invention mounts a germicidal lamp 6 in a drain trap and installs a photocatalytic material on the side and bottom surfaces of the trap. Spraying or baking 7 and arranging titanium oxide 8 as a deformed spherical filter medium on the upper surface of the water surface, and intermittently supplying hot water into the trap to kill germs and microorganisms growing in the sealed water, It is an object of the present invention to develop a detachable floor drain trap capable of blocking bacteria and separating and discharging an oil component adhering to the inside of the trap, thereby remarkably improving hygiene. According to the present invention, a commercially-available germicidal lamp 6 is mounted in the sealing water of a drain trap to kill germs and microorganisms growing in the sealing water and to trap the germs. By spraying or baking a photocatalyst on the inner surface, the ultraviolet light generated from the germicidal lamp 6 is used to redox organic substances in the trap, decompose into water and oxides, spontaneously decompose dirt, and produce a deodorizing effect. Then, the fungal cell membrane is decomposed and sterilized. In addition, hot water is intermittently poured into the trap body 3 from a hot water heater through the hot water inlet 5 to kill germs and microorganisms growing in the sealed water. These operations are controlled by a control panel and are performed automatically. According to the operation of the present invention, it is possible to kill germs and microorganisms growing in the sealed water of the drain trap by disinfecting lamp, photocatalytic action, hot water supply, and to block bacteria from the outside. It is possible to provide a floor drain trap with improved sanitary effects by maintaining and improving the trap function. Furthermore, by intermittently supplying hot water, it is possible to prevent the trap function from being impaired due to a shortage of the amount of sealed water, and to prevent the backflow of odor and harmful gas from the drain port. it can. [0008] In modern times, in medical facilities, food factories, and the like, attention is paid to the removal of invisible germs, microorganisms, dust, and the like in the air from buildings, electric supply facilities, water supply facilities, and air conditioning facilities. However, it has not been possible to kill bacteria and microorganisms that grow in the sealing water in the drain trap and to shut off the bacteria from the outside, to maintain and improve the original trap function and to improve the sanitary effect. However, the present invention has improved that. In the present invention, a germicidal lamp 6 is installed in contact with the sealing water 4 of the trap body 3 and controlled by a control panel, and the wastewater flowing from the trap lid 1 remains in the wastewater trap. Kills various germs and microorganisms that grow in the sealed water. According to the present invention, a titanium oxide photocatalyst material is sprayed or baked on the side and bottom surfaces of the trap body 3 in contact with the sealing water 4, and a deformed spherical titanium oxide is disposed above the water surface. Utilizing the generated ultraviolet light, the organic matter in the trap is redox-reduced, decomposed into water and oxide, and naturally decomposes the dirt to produce a deodorizing effect. Or kill microorganisms. In the present invention, hot water supplied from a water heater or a hot water supply pipe to the trap body 3 is intermittently poured from a hot water injection port 5 to prevent water from being cut off in the trap and to prevent water from being sealed. The control panel controls the water temperature so that it can be maintained at 70 ° C. for 30 minutes, and kills various bacteria and microorganisms that grow in the sealed water by heat. According to the present invention, the sealing of the floor drain trap is prevented from being reduced by evaporation or diffusion, and the germs or microorganisms that grow in the sealing water are killed, thereby enabling the isolation of bacteria from the outside. It can be applied to other traps. According to the present invention, it is possible to prevent reduction of water sealing due to natural evaporation, which is impossible with a conventional drain trap, and to kill germs and microorganisms growing on the sealing without impairing the function of the drain trap. And the trap function is maintained and improved.
Not only can a floor drain trap with improved sanitary effects be provided, but it is also possible to block bacteria from the outside.
