The present invention relates to a filter having a sterilization function capable of removing ticks, bacteria, bacteria, and the like filtered from a filter member by installing an ultraviolet light emitting diode (LED).
일반적으로 공기청정기나 진공청소기 등에 사용되는 에어필터(Air Filter)는 도 1에 도시된 바와 같이, 소정 형상의 필터케이스(1)와 이의 내부공간에 일정두께 또는 여러 겹으로 겹쳐서 제작된 필터부재인 여과지(2)를 장착함으로써 구성된다.In general, an air filter used in an air cleaner or a vacuum cleaner is a filter member manufactured by overlapping a predetermined thickness or multiple layers in a predetermined shape of the filter case 1 and its internal space, as shown in FIG. 1. It is comprised by attaching the filter paper 2.
근래에 들어서는 상기한 필터부재인 여과지로서 고효율의 입자제거를 목적으로 하는 헤파필터(HEPA Filter; High Efficiency Particulate Air Filter)를 이용하게 된다. 상기 헤파필터는 미세한 유해물질과 오염된 먼지까지도 걸러주는 특수 대전섬유인 석면섬유를 여과지로 적용함으로써, 강한 흡착력으로 공기에 함유된 인체에 해로운 먼지, 진드기, 바이러스, 곰팡이 등과, 인체에 가장 해로운 미립자인 0.3㎛ 크기의 먼지입자까지도 99% 이상 깨끗하게 제거하는 정화능을 가지고 있다.In recent years, a HEPA filter (High Efficiency Particulate Air Filter) for the purpose of removing particles with high efficiency is used as the filter paper as the filter member. The HEPA filter applies asbestos fiber, which is a special antistatic fiber that filters even harmful substances and contaminated dust, as a filter paper, and has a strong adsorptive power such as dust, mites, viruses, and fungi, which are harmful to the human body. Phosphorus 0.3㎛ dust particles have a purification ability to remove more than 99% clean.
상기한 기능을 지니는 헤파필터가 공기정화를 목적으로 하는 기기(공기청정기 또는 진공청소기, 제습기 등)에 적용되었을 경우, 공기 중에 함유된 유해한 입자를 99% 이상 제거할 수 있지만, 걸러진 입자를 살균처리할 수 있는 기능은 포함하고 있지 않기 때문에 여과지에서 박테리아, 진드기 또는 세균들이 2차 번식을 하게 되는 문제점이 있다.When the HEPA filter having the above functions is applied to an air purifying device (air cleaner or vacuum cleaner, dehumidifier, etc.), it is possible to remove 99% or more of harmful particles contained in the air, but the filtered particles are sterilized. Because it does not include the ability to do this, bacteria, ticks or germs in the filter paper has a second breeding problem.
상기한 바와 같이, 2차 번식된 인체에 해로운 박테리아, 진드기 또는 세균들은 기기의 사용시간이 증가함에 따라 그대로 공기 중에 방출되어 인체에 침투함으로써 사람에게 천식이나 알레르기를 일으키는 원인이 되고 있다.As described above, bacteria, mites, or bacteria that are harmful to the second propagated human body are released into the air as they are used, and thus penetrate the human body, causing asthma or allergies to the human being.
또한, 종래의 헤파필터는 사용시간이 증가할수록 2차 번식된 박테리아, 진드기 또는 세균으로 인하여 불쾌한 찌든 냄새나 인체 유해한 냄새를 발산하여 주거공간의 환경을 오염시키는 원인이 되고 있는 실정이다.In addition, the conventional hepa filter emits an unpleasant odor or harmful odor due to secondary breeding bacteria, mites, or bacteria as the use time increases, causing the environment of the living space to be polluted.

The filter according to the present invention is applicable to any filtration device having a filtration function for filtering and purifying any fluid (water, oil, air, gas, etc.). That is, it is applicable to all filtration devices for purifying fluids such as air filters for vacuum cleaners as well as air filters for vacuum cleaners and water filters.
예를 들어 진공청소기(20)에 본 발명의 살균기능이 있는 필터가 적용될 경우 청소기(20)의 전원공급부와 본 발명의 PCB기판(14)이 연결되어 자외선 발광다이오드(13)에 전원을 인가하게 됨으로써 자외선이 조사되도록 하며, 이러한 조사시간은 진공청소기(20)를 제어하는 제어부에서 조절되어 기기가 작동할 때 또는 작동이 멈춘 후 소정시간동안, 아니면 기기의 충전시간 동안 필터부재(10) 및 광촉매층(12)에 자외선을 조사하여 살균작용을 하도록 한다.For example, when the filter having the sterilization function of the present invention is applied to the vacuum cleaner 20, the power supply unit of the cleaner 20 and the PCB substrate 14 of the present invention are connected to apply power to the ultraviolet light emitting diode 13. Thereby irradiating ultraviolet rays, and the irradiation time is controlled by a control unit controlling the vacuum cleaner 20 so that the filter member 10 and the photocatalyst during the predetermined time after the operation of the device or the operation stops, or during the charging time of the device. Ultraviolet rays are irradiated onto the layer 12 for sterilization.
본 발명의 진공청소기(20)에 적용된 살균기능이 있는 필터는 진공청소기(20)가 흡입하는 공기통로에 착탈 가능하도록 장착되어 흡입된 공기 중에 포함된 먼지 및 진드기를 필터링하며, 필터링되어 필터부재(10) 상에 존재하는 진드기 또는 세균, 박테리아를 필터에 장착된 자외선 발광다이오드(13)가 자외선을 발광하여 박멸하게 되는 것이다.The filter having a sterilization function applied to the vacuum cleaner 20 of the present invention is mounted to be detachable from the air passage where the vacuum cleaner 20 is inhaled, and filters dust and mites contained in the inhaled air, and is filtered. 10) The ultraviolet light emitting diode 13 mounted on the mite, bacteria or bacteria present on the filter emits ultraviolet rays and is extinguished.
즉, 본 발명의 진공청소기에서는 설치된 자외선 발광다이오드(13)로부터 조사되는 자외선의 파장이 200~300㎚인 직접살균 파장대의 경우에는 자외선을 그대로 필터부재(10)에 조사시켜 멸균 및 탈취작용을 하도록 하며, 자외선의 300㎚ 이상의 간접살균 파장대일 경우에는 설치된 광촉매층(12)에 의한 광촉매효과에 의해서 멸균 및 탈취작용이 일어나도록 하는 것이다.That is, in the vacuum cleaner of the present invention, in the case of the direct sterilization wavelength band of the ultraviolet light emitted from the ultraviolet light emitting diode 13 installed in the range of 200 to 300 nm, the ultraviolet light is irradiated to the filter member 10 as it is to be sterilized and deodorized. In the case of an indirect sterilization wavelength band of 300 nm or more of ultraviolet rays, sterilization and deodorization are caused by the photocatalytic effect of the photocatalytic layer 12 installed.
또한, 본 발명에서 여과기기에 장착되는 살균기능이 있는 필터는 기기 내부의 유체통로 상에 착탈이 용이하도록 여과기기에 형성된 고정홈에 삽입식으로 고정되는 방식 등과 같이 고정되어 필터의 수명이 다하거나 파손되면 교체가 용이하도록 하는 것이 바람직하다.In addition, the filter having a sterilization function mounted on the filtration device in the present invention is fixed in such a way that the filter is inserted into a fixing groove formed in the filtration device to be easily removable on the fluid passage inside the device when the end of the filter life or when broken It is desirable to facilitate the replacement.
상술한 바와 같이, 본 발명은 자외선 발광다이오드를 유체를 여과하는 필터에 장착하여 걸러진 진드기나 세균들을 자외선으로 조사하여 살균 및 제거함으로써 2차 번식을 방지할 수 있다. 또한 본 발명은 자외선의 파장대에 따라 광촉매가 코팅된 광촉매층을 이용하여 직접적인 살균작용이 없는 파장대의 자외선의 파장에서도 광촉매 현상을 이용하여 세균에 대한 강력한 살균, 항균, 탈취효과가 나타나도록 하였으며, 특히 자외선 발광다이오드는 소비전력이 종래의 자외선 수은램프보다 월등히 낮을 뿐 아니라 사이즈가 현저히 작기 때문에 필터와 최대한 근접하도록 설치될 수 있어 살균효과가 향상되는 효과가 있다. 또한, 본 발명의 자외선 발광다이오드는 내구성 및 내충격성이 우수하여 살균효과가 오래 지속되는 효과가 있다.As described above, the present invention can be equipped with an ultraviolet light emitting diode to filter the fluid to prevent secondary breeding by irradiating the filtered ticks or bacteria with ultraviolet rays to sterilize and remove. In addition, the present invention uses the photocatalyst layer coated with a photocatalyst according to the wavelength of the ultraviolet light, the photocatalytic phenomenon is used even in the wavelength of ultraviolet light in the absence of direct sterilization effect, especially to show a strong bactericidal, antibacterial, deodorizing effect on bacteria. Ultraviolet light emitting diodes can be installed as close to the filter as possible because the power consumption is much lower than conventional ultraviolet mercury lamps and the size is remarkably small, so that the sterilization effect is improved. In addition, the ultraviolet light emitting diode of the present invention is excellent in durability and impact resistance has a long lasting sterilization effect.
