Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a circulating hot water purification device by photocatalytic sterilization.

[0002]

[Prior art]

 It has been recognized that conventional ultraviolet lamps alone have a sterilizing effect.

[0003]

[Problems to be solved by the device]

 Legionella bacteria and other bacteria are present in hot water such as water heaters and humidifiers, which is a problem that can be used anytime, such as the convenient 24-hour bath, which has become a problem. Therefore, the development of a sterilizing and purifying device for hot water free of Legionella bacteria even in a 24-hour bath is awaited.

[0004]

[Means for Solving the Problems]

 Therefore, in view of the above circumstances, the present invention has an inflow inlet for inflowing hot water and an outflow outlet for outflowing the inflowing hot water in the circulating hot water system, in order to achieve a highly efficient sterilization effect. A circulating hot water purifying device by photocatalytic sterilization comprising a tank coated with titanium and an ultraviolet lamp housed in the tank.

[0005]

[Embodiment of the invention]

 The present invention will be described in detail below based on specific embodiments shown in the accompanying drawings. In the present invention, when the titanium oxide coated on the inner surface of the tank is irradiated with ultraviolet rays, a photochemical reaction occurs and strong sterilization, decomposition, and deodorizing action occur as a photocatalyst. This light source is also sterilized by using an ultraviolet lamp that has sterilizing power. It is designed to double the effect.

When the coated titanium oxide is irradiated with light, it has a strong oxidizing power activated by light energy. This is called a photocatalyst, which kills many bacteria and organic substances in contact with the surface in seconds. It has the property of decomposing. The characteristics of this photocatalyst are utilized in the present invention. In FIG. 1, a cylindrical tank 1 (container) is provided with an inflow port 3 for inflowing circulating hot water and an outflow port 2 for outflowing the warm water flowing into the tank 1, the inner surface of which is coated with titanium oxide. Has been done. The hot water in the water tank is pumped up by the pump, enters the tank 1 through the inflow port 3, passes through the inside, and flows out through the outflow port 2.

In this tank 1, an ultraviolet lamp 5 is housed and arranged in a quartz protection tube 4. Reference numeral 6 is a socket of the ultraviolet lamp 5, reference numeral 7 is a lead wire of the ultraviolet lamp 5, and reference numeral 8 is a cap. The hot water pumped up by the pump flows into the tank 1 through the inflow port 3 of the purification device, passes through the tank 1, and flows out through the outflow port 2. At that time, when electricity is supplied from the lead wire 7, the ultraviolet lamp 5 is turned on and the titanium oxide coating surface inside the tank 1 is irradiated. The hot water flowing into the tank 1 is sterilized by the ultraviolet lamp 5 and also sterilized by the action of the photocatalyst on which the titanium oxide coated on the inner surface of the tank 1 by the irradiation of the ultraviolet lamp 5 acts. Therefore, in the present purifying device, not only the ultraviolet lamp 5 is used for sterilization, but also the photocatalytic action of titanium oxide is generated at the same time to synergistically enhance the sterilizing effect of both of them.

The purification apparatus of the present invention exhibits a high bactericidal effect against all kinds of bacteria such as Legionella bacteria, Escherichia coli, Pseudomonas aeruginosa, MRSA existing in water in a circulating water tank. In addition to the bactericidal action, the photocatalyst also decomposes and removes dead bacteria and organic pollutants, so that it degrades and alters the quality of hot water, especially by degrading the fatty acids that are the main cause of slime in the aquarium. Prevent and always purify the aquarium.

In the present invention, the ultraviolet lamp and the photocatalyst can be made to act at the same time, and a highly effective bactericidal effect can be utilized.

[0010]

[Effect of the invention]

 As described above, the present invention comprises a tank having an inlet for introducing hot water, an outlet for discharging the inflowing hot water, a tank whose inner surface is coated with titanium oxide, and an ultraviolet lamp housed in the tank. Since it is a circulating hot water purification device using photocatalytic sterilization, it is possible to use both the ultraviolet lamp and the photocatalyst at the same time to synergistically enhance the sterilizing effect of both.
