Personal sterilizer having air purification function{Personal sterilizer having air purification function}

The present invention relates to a personal sterilization apparatus, and more particularly, to a personal sterilization apparatus having an air purification function for sterilizing and drying personal items and purifying ambient air.

In a generally used ultraviolet sterilizer, a shelf for placing cups or bowls is installed inside, and a lamp emitting ultraviolet wavelength is installed on the ceiling inside the sterilizer to sterilize cups or bowls placed inside the sterilizer.

These ultraviolet sterilizers have been mainly used in places where a clean phase state is required, such as a general restaurant, but the range of use in recent years is expanding. For example, the spread rate of personal sterilizers for personal hygiene is increasing.

Meanwhile, as the recent trend of consumers demands various functions rather than one function, personal sterilizers are also required to include various functions as well as sterilization functions, and research to meet these demands is in progress.

The air purifying unit 40 is installed below the ultraviolet sterilizing unit 40 of the main body 10 and purifies air by filtering volatile organic compounds contained in the air. Here, the air purification unit 40 is positioned so as to be exposed to the outside of the main body 10, thereby providing convenience so that the user can easily perform maintenance such as cleaning and washing. The air purification unit 40 includes a photocatalytic filter 41 and a nylon filter 42.

The photocatalytic filter 41 absorbs and filters volatile organic compounds contained in air using a photocatalyst. Here, the photocatalysts are titanium dioxide (TiO ₂ ), zinc oxide (ZnO), niobium pentoxide (Nb ₂ O ₅₃ ), tin oxide (SnO ₂ ), cadmium sulfide (CdS), cadmium telluride (CdTe). And the like, and preferably may be titanium dioxide. The photocatalyst filter 41 may be formed as a single filter by overlapping a plurality of filters, and a plurality of filter holes 41a may be formed to increase a contact surface with air and ultraviolet rays. At this time, the photocatalytic filter 41 causes a photochemical reaction when it comes into contact with ultraviolet rays.

For example, titanium dioxide generates electrons and holes when it comes into contact with ultraviolet rays irradiated by the ultraviolet sterilization unit 30. At this time, electrons and holes react with oxygen (O ₂ ) and water vapor (H ₂ O) in the air, respectively, to generate superoxide anions and hydroxyl radicals, which are two types of active oxygen on the surface of titanium dioxide. Here, since hydroxyl radicals have high oxidation and reduction potential, they are excellent in purifying NO _x , SO _x , volatile organic compounds and various odors. Aquatic radicals can not only remove pollutants and environmental hormones, but also oxidize target materials by sterilizing more than 99% of fungi and bacteria. In addition, in the photocatalytic filter 41, when ultraviolet rays are irradiated from the ultraviolet sterilization unit 30, one of two oxygens constituting titanium dioxide reacts with water vapor in the air to generate hydrophilic water (-OH) having very good hydrophilicity. Through this, the photocatalytic filter 41 has fouling resistance to prevent adsorption of contaminants on the surface, and has self-cleaning property that allows the attached contaminants to be easily washed by rainfall or water.
