Description

Air sterilizer for lighting {Air sterilizer for lighting}

The present invention relates to an air sterilizer for lighting, and more specifically, a slim air sterilizer is applied to the rear of a lighting unit that is attached and used as close to the indoor ceiling as possible so that the UV light source for air sterilization is not directly visible to the user. Of course, the UV light source module provided inside each air sterilizer forms an air flow path that facilitates heat dissipation, and efficiently sterilizes the heat emitted from the UV light source module and the heat emitted from the lighting, making indoor air more comfortable. This is about an air sterilizer for lighting.

In general, with the development of industry, air pollution has become serious, and many people are suffering from various diseases, including respiratory bronchitis, due to these pollutants.

As a countermeasure against air pollution, people are creating a more comfortable environment by purifying the air indoors, such as residential homes or offices, using air purifiers.

Most air purifiers have a structure that uses multiple stages of filters, and filter out bacteria (mold, etc.) sucked in from the air depending on the application of the filters, but there is the inconvenience of frequently changing the filters on a regular basis. Additionally, since the filter does not kill bacteria, it has the disadvantage of allowing bacteria to live and reproduce in the filter, and when the air conditioning is poor, more polluted air can only be emitted.

For example, air purifiers sometimes use electric dust collectors to improve air purification performance, but it is pointed out that this generates a large amount of ozone and has minimal dust collection and pollutant removal performance, making it unsuitable for use in homes or offices.

In addition, air purifiers take up indoor space, are not aesthetically pleasing, and have limitations in sterilizing bacteria floating in the air.

In response to this, there is an urgent need for the development of environmentally friendly air cleaning technology that generates less noise, is smaller in size, consumes less power, and is environmentally friendly.

Meanwhile, looking at the source technology related to air sterilization, Republic of Korea Patent No. 10-2295502 (name: UVC-LED air sterilizer, hereinafter referred to as 'Patent Document 1'), Publication Patent No. 10-2013-0067568 (name: Lighting device with air purification function, hereinafter referred to as ‘Patent Document 2’) and Registration Patent No. 10-2401778 (name: Air sterilizer using UV-C LED, hereinafter referred to as ‘Patent Document 3’) are disclosed. It is done.

Patent Document 1 improves the existing HEPA filter method, which has high resistance to air passage, by improving the existing HEPA filter method that introduces droplets and floating viruses into the air sterilizer through an adsorption brush installed in a flow path structure with droplet and virus adsorption characteristics, and UVC-LED. This is a technology for a UVC-LED air sterilizer that sterilizes and then exhausts air to protect the user and surrounding people from various contaminants and viruses.

Patent Document 2 discloses that a reflector is installed on the main body, a lighting installation part for storing fluorescent lights is formed in the lower space of the main body partitioned by the reflector, and indoor air is drawn into the upper space of the main body partitioned by the reflector for UV sterilization. An air purification unit is provided to prevent indoor residents from being exposed to the ultraviolet rays of the UV sterilizing lamp. It is safe to use and the reliability of the product is high. An intake fan is installed on the exhaust side, and the indoor air is sterilized by a sterilizing lamp before the intake fan. By forming a flow path to pass through, the air purification efficiency can be improved.

Patent Document 3 discloses that LEDs are arranged in a staggered manner on both sides of the tube-shaped housing, where air flows, instead of facing each other, a reflector is installed on the inner surface of the sterilization space, and a front end of the housing is installed. This is an air sterilizer using UV-C LED that is small in size and significantly increases sterilizing power by installing a speed-adjustable blower at the rear and rear ends to control the flow rate of air within the housing.

The air sterilizer disclosed in Patent Documents 1 and 3 is an air sterilizer installed in an externally visible location, requires a separate mounting space, and is intended for air sterilization using a single UV-C LED.

Patent Document 2 is equipped with a UV air sterilization and air purification function inside the lighting lamp. This is usually suitable for being embedded in the ceiling of an office, but the installation thickness along with the lighting lamp is considerable, so it takes up some space to be used in the living room or room of a general home. It has a disadvantage in terms of aesthetics.

It can also be configured as a type in which an air inlet portion 11a that can communicate with the inside of the main body 10 where the intake hole 10a is formed is formed on one side of the fan seating portion 11.

This is to help dissipate the heat from the light source itself and simultaneously sterilize the air, including the subtle heat radiation odor that occurs when the light is turned on.

The upper cover 20 has a rectangular shape and is detachably coupled to the open upper part of the main body 10. In more detail, a plurality of coupling parts provided on the rear of the upper cover 10 are formed as one body, which are inserted into the main body and fixed with fastening screws provided at the rear.

On both sides of the upper cover 20, a grill 21 is provided to be detachable along with a dust filter 22 to match the position of the fan seating portion 11.

The grill 21 is guided to the side of the intake port 20a provided on the upper cover 20, and is assembled by inserting a coupling protrusion provided on the edge of the grill 21 into a coupling groove provided on the intake port side, and the dust filtration As shown in FIG. 3, the filter 22 is mounted on the intake port at the rear of the grill to filter dust or foreign substances in the air.

The vibration-proof pad 40 is guided and fixed to the fan seating portion 11 of the main body 10 and is attached to the blower fan 30 for blowing air toward the air outlet 14 and the bottom of the blower fan 30 to prevent vibration. Let's do it.

Meanwhile, the internal space (11b) formed between the outside of the fan seat 11 and the inside of the main body, which is partitioned and provided inside the main body 10, is exposed to the air from the fan seat 11 when the blowing fan 30 is operated. A first vibration isolation pad 40' is inserted and provided to block vibration conducted to the outside of the main body 10.

The internal space 11b of the main body 10 where the first anti-vibration pad 40' is inserted is guided to the corresponding position among the plurality of coupling parts provided on the rear of the upper cover 20, thereby forming the inner space 11b of the main body 10. Since it is the position screwed on the bottom and the position where the fan seating portion 11 and the main body are closest, by inserting the first anti-vibration pad 40', the anti-vibration pad inserted into the fan seating portion 11 ( Together with 40), it serves as a vibration isolation space and is a space that can block vibration generated from the motor due to the operation of the blowing fan (30).

Meanwhile, the UVC light source module 50 is installed facing up and down on the air passage 12 of the main body 10 to sterilize bacteria in the air flowing out toward the air outlet 14 by blowing from the blower fan 30. In this way, multiple UVC-LED elements are arranged on a PCB board to sterilize the air by irradiating light in a face-to-face manner.

The air guide member 60 is a member installed on the air passage 12 of the main body 10 and guides the air distribution toward the outlet 14 to help discharge, and the guide piece 62 is tilted on the fixing plate 61. An array is formed attached.

As an example, the guide pieces 62 are arranged in deviated lengths as shown in the attached FIG. 8. This is to ensure that air is discharged as uniformly as possible through the air outlet 14 on the main body 10 by varying the discharge flow rate of the air induced and discharged through guide pieces of different lengths.

The fixing plate 61 and the guide piece 62 of the air guide member 60 are located on the air passage and are made of either aluminum or stainless steel, which is advantageous for effectively dissipating heat generated from the UVC light source module 50. It is manufactured from metal materials.

The operation of the air sterilizer for lighting according to the present invention configured as described above is described as follows.

The air sterilizer 100 according to the present invention is slim and is located on top of the lighting lamp 1 attached to the ceiling to sterilize and purify indoor air.

The operation of the air sterilizer 100 provided on both sides of the upper cover 1 sucks in external air through the grill 21 on the upper cover 20 by operating the blowing fan 30 located therein.

The dust filter 22 disposed at the rear of the grill collects and filters dust and foreign substances contained in the air.

The inflow of external air by the operation of the blowing fan 30 provided in the fan seating part 11 of the main body 10 is caused by UVC light source modules installed to face each other in the air passage along the air passage 12 on the inner side of the main body 10. It passes through (50), and various bacteria contained in the air are killed by the light emitted from the UVC light source module (50) and discharged through the air outlet (14) on the main body (10).

In the forced intake, sterilization, and discharge of air as described above, air blowing is performed so that the air sent from the fan seating portion 11 is discharged along the gradually narrowing air flow path 12, so the air is discharged and circulated quickly. This comes true.

Air is divided and discharged from the air guide member 60 installed on the air passage 12.

Air is discharged along the inclined guide piece 62 on the fixed plate 61 constituting the air guide member 60, with respect to the partition wall 13 provided at the center of the air passage 12 located on the left and right sides, respectively. Air discharge occurs simultaneously.

As shown in the attached FIG. 8, the guide pieces 62 are formed to have different lengths, so that the air flow speeds up toward the partition wall 13, ultimately resulting in uniform delivery on both sides of the air outlet 14. Air is discharged by wind power.

In addition, the heat generated when the UVC light source modules 50 arranged on both sides along the air passage 12 as described above are turned on is generated by the air in which the guide piece 62 and the fixing plate 61 are made of aluminum or stainless steel. It is possible to simultaneously implement air guidance and heat dissipation of the guide member 60.

In air sterilization as described above, the blowing fan 30 is used as described above through the air intake hole 10a on the main body 10 side and through the air inlet 11a formed on the fan seating part 11 inside the main body 10. Air suction is achieved by driving, which makes it possible to simultaneously remove fine heat radiation odors generated when the light source is radiated by turning on the lighting lamp (1) and perform air sterilization at the same time.

For reference, the recent ceiling-mounted lighting is mainly of the LED type, which boasts brightness and long lifespan compared to the fluorescent lighting type. LED lighting also comes in a type that attaches a circuit board and a heat sink together depending on the intensity of brightness (lumens). In order to achieve this, output must increase and natural heat generation must increase to dissipate heat.

Therefore, by placing the air sterilizer 100 as described above on the upper part of the lighting lamp 1, it can help not only sterilize the indoor air but also eliminate the heat dissipation part that is close to the lighting lamp, and this effect extends the service life of the lighting lamp. It also has a prolonging effect.

Meanwhile, in the operation of the blowing fan 30 according to air sterilization as described above, the inside of the fan seating portion 11 and the internal space 11a between the fan seating portion 11 and the main body 10 are The vibration isolation pad 40 and the first vibration isolation pad 40' block the vibration conducted by the operation of the blower fan 30, thereby creating a quiet air flow.

The air sterilizer 100 according to the present invention is operated at the top of a lighting fixture installed close to the ceiling, that is, at a position close to the ceiling. Ultraviolet rays are emitted from the outside by the lighting operation of the UVC light source module through the existing indoor stationary type air sterilizer. It has the advantage of not being exposed to the elements, so there is no discomfort in indoor living.
