Description

Portable air purifier{PORTABLE AIR CARING APPARATUS}

The present invention relates to a portable air purifier, and more specifically, to a portable air purifier that uses sterilizing light to sterilize the filter unit.

An air purifier is a device widely used in modern life. It is a device that purifies the air by filtering out physical particles such as dust, fine dust, and ultrafine dust, chemical substances such as odor particles and harmful gases, and microorganisms such as bacteria and viruses. .

Air purifiers have become an indispensable device even in ordinary homes due to the influence of urbanization, industrialization, and internationalization. In addition, the demand is rapidly increasing due to the influence of the increase in fine dust, the increase in allergy patients, and the improvement of living standards.

When the air purifier is intended for an environment exceeding 100㎡, such as an ordinary home, the size of the device may be larger. In such devices, filters corresponding to physical particles such as dust, filters corresponding to chemical substances such as gas, and filters corresponding to microorganisms such as bacteria and viruses may be used in combination. That is, in large spaces, a large-sized air purifier that can accommodate various filters can be used.

However, using a large air purifier in a small space such as a studio or inside a car is inefficient in terms of space utilization, mobility, and energy consumption. Additionally, for users who move frequently, a small air purifier that can be used individually and portable is more suitable than a large air purifier. Against this background, portable air purifiers that can be used by individuals on a portable basis are being developed.

Portable air purifiers are provided in a small and lightweight form for easy portability. These portable air purifiers have the advantage that users can easily carry them around and use them wherever they want. In other words, a portable air purifier is a device suitable for users who have a lifestyle pattern of going out frequently or moving to multiple places rather than staying in one place, such as home, for a long time.

In the prior art (Korean Patent Publication No. 2020-0037187), air is sucked in from the back of a portable air purifier and the air is discharged to the front. The air that flows into the back of the portable air purifier goes through a filter and blower fan and is then discharged directly to the front of the portable air purifier.

However, since the external size of the portable air purifier is set for easy portability, there is a problem in that a sterilizing unit for sterilizing the filter cannot be installed separately inside the housing unit.

Additionally, when using sterilizing light to sterilize the filter unit, there is a problem in that part of the sterilizing light is exposed to the outside of the housing.

[Sterilization Department]

Figure 7 is a partially cut away perspective view of the sterilizing support unit 210 according to the first embodiment of the present invention, and Figure 8 shows the sterilizing unit 200 according to the first embodiment of the present invention installed on the lower side of the filter unit 40. This is a drawing showing the state.

As shown in FIGS. 1, 7, and 8, the sterilizing unit 200 is installed below the filter unit 40 and may be installed at the same height as the inlet unit 22. Since the sterilizing unit 200 and the inlet 22 are installed at the same height, space utilization is improved compared to an air purifier with the sterilizing unit 200 installed on the upper side of the inlet 22, and the height of the housing unit 10 can also be lowered. The sterilizing unit 200 can be transformed into various shapes within the technical philosophy of sterilizing the filter unit 40 by irradiating sterilizing light. The sterilizing unit 200 according to the first embodiment of the present invention includes a sterilizing support unit 210 and an irradiation unit 280.

The sterilization support part 210 supports the irradiation part 280 and is fixed to the housing part 10. In addition, the sterilization support part 210 can be modified in various ways within the technical concept of being installed along the outer circumference of the irradiation part 280. The sterilization support part 210 according to the first embodiment of the present invention is fixed to at least one of the first case part 20 and the second case part 30. Additionally, the sterilization support portion 210 may include a support body portion 220 and a support bracket 270.

The support body portion 220 is installed along the outer circumference of the irradiation portion 280, and various modifications are possible within the technical idea of reflecting the sterilizing light irradiated from the sterilizing light source 282 to the filter portion 40. The support body portion 220 according to the first embodiment of the present invention may include at least one of the reflection portion 230, the inner support portion 240, the heat dissipation hole portion 250, and the blocking body 260.

The reflection unit 230 is installed in a concave shape toward the filter unit 40, and the sterilizing light source 282 of the irradiation unit 280 is located at the center. The reflection unit 230 reflects the light emitted from the sterilizing light source 282 of the irradiation unit 280 in a direction toward the filter unit 40.

Additionally, the reflecting part 230 may be located inside the housing part 10 facing the inlet part 22. Since the ultraviolet rays used as the sterilizing light source 282 are harmful to the human body, the support body 220 including the reflecting part 230 is installed so that the sterilizing rays are not irradiated to the outside of the housing part 10. A reflecting part 230 is installed to block the sterilizing light from being irradiated to the housing part 10, which is an injection molded product, in addition to the filter part 40, or from leaking to the outside of the housing part 10 through the inlet part 22. The reflection unit 230 is designed considering the radiation angle of the sterilizing light and the area of the filter unit 40.

The reflector 230 has a funnel shape with an open top, and the top of the reflector 230 is located on the same line as the top of the inlet 22 or is located at a higher position than the top of the inlet 22. Therefore, it is possible to block the sterilizing light generated from the sterilizing light source 282 from being irradiated to the outside of the entrance portion 22.

Additionally, the angle of the reflector 230 is designed so that the reflector 230 does not restrict the sterilizing light going to the edge of the filter unit 40. The reflecting unit 230 according to the first embodiment of the present invention includes a first reflecting body 232 and a second reflecting body 234.

The first reflecting body 232 is installed along the circumference of the sterilizing light source 282 and is spaced apart from the sterilizing light source 282 at a set interval (D).

The second reflecting body 234 extends from the first reflecting body 232 in an upwardly inclined direction. The second reflecting body 234 according to the first embodiment of the present invention has a funnel shape with an open upper side, and the inner diameter may gradually increase from the first reflecting body 232 toward the filter unit 40.

And a reflective coating layer may be formed on the surface of the reflector 230. A material with high reflectivity, such as aluminum or chrome, may be coated on the surface of the injection molded reflector 230 so that the reflector 230 functions as a reflector.

A coating layer may be formed only on the first reflecting body 232 facing the sterilizing light source 282, and if necessary, a coating layer may also be formed on the second reflecting body 234. When aluminum reflective coating is applied to the reflective portion 230, the reflectivity can be 90%.

And the reflecting surface of the first reflecting body 232 facing the sterilizing light source 282 is installed to form a set angle (F) with the horizontal line. The setting angle (F) of the reflecting surface according to the first embodiment of the present invention has an inclination angle of 80°±5°. Therefore, the sterilizing light irradiated from the sterilizing light source 282 is irradiated directly to the edge of the filter unit 40, or is reflected by the first reflecting body 232 and then irradiated to the edge of the filter unit 40. losses can be minimized. By installing the reflector 230 like this, the average illuminance is improved by 6% and the minimum illuminance is improved by 26% based on UVC-LED 10mW.

In addition, when the distance between the sterilizing light source 282 and the filter unit 40 is referred to as the first length (G1), and the radius of the lower surface of the filter unit 40 is referred to as the second length (G2), the first length The second length (G2) is longer than (G1). The second length (G2) according to the first embodiment of the present invention is 1.8 to 2.2 times the first length (G1).

The inner support part 240 extends below the reflection part 230 and can be modified in various ways within the technical concept of supporting the printed circuit board 281 of the irradiation part 280. The inner support portion 240 according to the first embodiment of the present invention includes an inner bracket 242 extending to the lower side of the reflecting portion 230 and bending inward from the lower side of the inner bracket 242 toward the irradiation portion 280. and may include a catching hook 244 that is caught on the edge of the irradiation unit 280.

The inner support portion 240 is provided in plurality and extends below the reflection portion 230. The inner support part 240 operates in a hook manner and is caught on the outer edge of the printed circuit board 281, so that the printed circuit board 281 can be fixed to the inside of the support body part 220.

The heat dissipation hole part 250 forms a plurality of holes in the reflection part 230. Since air moves through the heat dissipation hole 250, the irradiation unit 280 is air-cooled. The heat dissipation hole portion 250 may include a plurality of arc-shaped long holes centered on the sterilizing light source 282. In the heat dissipation hole portion 250, a slit hole extending in an arc shape is installed centered on the sterilizing light source 282. By installing the heat dissipation hole 250, the printed circuit board 281 of the irradiation unit 280 located on the lower side of the irradiation unit 280 is air-cooled, so the heat dissipation performance of the sterilizing light source 282 using UVC LED can be improved. .

The blocking body 260 extends downward from the outer edge of the reflector 230. The blocking body 260 has a cylindrical shape with an open lower side, and the center of the blocking body 260 coincides with the center of the inlet portion 22. Since the blocking body 260 is installed, even if the sterilizing light source 282 is radiated from the irradiation unit 280 to the lower side of the reflecting part 230, the blocking body 260 blocks the movement of the sterilizing light source 282. Therefore, when the sterilizing light is to be irradiated to the outside of the housing part 10 through the entrance part 22, the first blocking is done in the reflecting part 230, and the second blocking is done in the blocking body 260.

The support bracket 270 extends to the lower side of the support body 220 and is fixed to the housing 10. Various modifications are possible within the technical idea. The support bracket 270 extends to the lower side of the support body 220 and is fixed to at least one of the first case part 20 and the second case part 30, or is attached to the upper side of the second case part 30. It may be fixed to the inner housing 35 that shields it.

The support bracket 270 according to the first embodiment of the present invention is coupled to the plate-shaped inner housing 35 in a hook shape. Therefore, since the sterilization unit 200 is easy to install and disassemble, the time and cost required for maintenance work can be reduced.

The irradiation unit 280 is located below the filter unit 40, is installed at a height overlapping with the inlet unit 22, and irradiates sterilizing light toward the filter unit 40. Additionally, the movement of the irradiation unit 280 is restricted by the sterilization support unit 210, and may be located on a vertical reference line penetrating the radial center of the inlet unit 22 in the vertical direction. The vertical reference line forms a straight line identical to the extension of the axis of rotation. Additionally, the centers of the first case unit 20, the filter unit 40, the fan module unit 70, and the irradiation unit 280 may coincide in the vertical direction.

Therefore, when the filter unit 40 is located on the upper side of the irradiation unit 280, the entire lower area of the filter unit 40 can be sterilized even by the sterilizing light source 282 with a relatively small amount of light, thereby reducing production and maintenance costs. You can save money.

In addition, the irradiation unit 280 can be implemented in various modifications within the technical idea of being installed at the same position or higher than the top of the inlet unit 22. The irradiation unit 280 according to the first embodiment of the present invention may include a printed circuit board 281 and a sterilizing light source 282. A printed circuit board 281 is fixed to the inside of the sterilizing support part 210, and a sterilizing light source 282 that irradiates sterilizing rays is installed on the top or inside of the printed circuit board 281.

The printed circuit board 281 is caught on the inner support part 240 provided in the support body part 220, and its movement is restricted. And the sterilizing light source 282 installed on the printed circuit board 281 is located below the filter unit 40 and radiates sterilizing light at a set irradiation angle toward the upper side where the filter unit 40 is installed. Since the radial centers of the sterilizing light source 282 and the filter unit 40 coincide in the vertical direction, the sterilizing light source can be uniformly irradiated to the lower part of the filter unit 40.

The sterilizing light source 282 may be a UVC LED, and in addition, various types of sterilizing devices may be used within the technical scope for sterilizing bacteria in the filter unit 40.

On the other hand, even if the sterilizing light source 282 of the sterilizing unit 200 is installed at the same height as the entrance part 22, the reflecting part 230 is installed along the circumference of the sterilizing light source 282, so the sterilizing light is transmitted to the entrance part ( 22), it is possible to prevent irradiation to the outside of the first case portion 20.

Conventionally, because the irradiation angle of UVC LED that irradiates sterilizing light is limited, if an appropriate distance is not secured between the filter unit 40 and the UVC LED, it is difficult to implement sterilizing performance up to the edge of the filter unit 40. It has a problem.

However, since the present invention installs the reflector 230 and forms a reflective coating on the reflector 230, the sterilizing light can be uniformly irradiated to the lower part of the filter unit 40, thereby improving sterilizing performance. The reflector 230 installed along the outer circumference of the irradiation unit 280 is installed in a funnel shape to reflect the sterilizing light in the direction toward the filter unit 40, and the reflector 230 is coated with a reflective coating to have a high reflectivity. Therefore, the irradiation angle and irradiation distance of the sterilizing light can be secured even within a limited space.

[Air flow and sterilization of portable air purifier]

Since the inlet part 22 for sucking in external air is installed along the outer circumference of the first case part 20, the air on the outside of the first case part 20 enters the first case part through the inlet part 22. By moving to the inside of (20), the intake flow rate of air can be increased.

By operating the fan module unit 70, air from outside the portable air purifier (1) flows into the portable air purifier (1). At this time, the air outside the portable air purifier (1) passes through the inlet hole (23) and forms a spiral air flow that rotates around the outer circumference of the inner support portion (240).

The air that flows into the inside of the first case 20 and rotates spirally and rises rotates around the sterilization unit 200 and moves upward toward the filter unit 40. And the air that has passed through the filter unit 40 moves to the upper side of the housing unit 10 through the fan module unit 70.

In the process of passing through the filter unit 40, physical particles such as dust, fine dust, and ultrafine dust contained in the air, chemical substances such as odor particles and harmful gases, and microorganisms such as bacteria and viruses are filtered out. You can.

Since the filter unit 40, the fan module unit 70, and the rotation support unit 300 are arranged in a straight line in the vertical direction, effective intake and filtering of air can be achieved while flow loss is minimized.

The air introduced into the fan module unit 70 is discharged to the upper side of the fan module unit 70 and moves to the inside of the discharge unit 140. Since the discharge unit 140 rotates within a set angle range, the direction of the discharged air can be adjusted depending on the installation angle of the discharge unit 140.

In addition, since the inside of the discharge unit 140 forms a concave groove, an increase in discharge resistance of air whose direction has been changed through the discharge unit 140 can be reduced. In addition, since the filter unit 40, the fan module unit 70, and the discharge unit 140 are arranged in a straight line in the vertical direction, effective air intake, filtering, and discharge of purified air can be achieved while minimizing air flow loss. You can.

Bacteria floating in the air are captured in the filter unit 40, and the sterilizing light irradiated from the sterilizing light source 282 is irradiated to the lower part of the filter unit 40. The sterilizing light is irradiated directly to the filter unit 40 or is reflected by the reflector 230 and then irradiated to the lower part of the filter unit 40 to perform a sterilizing effect.

The sterilizing light source 282 uses a wavelength of 275 nm, which has a high sterilizing efficiency, as a sterilizing light source, and considering the UV irradiation range and filter reliability of the surface of the filter unit 40 using a HEPA filter, the irradiation distance is the first length (G1). ) is set to around 17.7mm.

When the distance between the filter unit 40 and the sterilizing light source 282 is short, the sterilizing performance increases, but when used for a long time, the appearance of the filter unit 40 may be damaged or the particle removal performance may decrease due to deterioration of the filter unit 40. You can. Additionally, if the appropriate distance between the filter unit 40 and the sterilizing light source 282 is not maintained, the amount of light reaching the edge of the filter unit 40 may decrease, thereby reducing sterilizing performance. Therefore, by installing the sterilizing unit 200 according to the present invention, surface roughness can be secured up to the edge of the filter unit 40, and conditions for ensuring the reliability of the filter unit 40 can be secured.

When installing the portable air purifier (1) with the sterilizing unit (200) in a vehicle, bacteria and viruses floating in the vehicle are attached to the filter unit (40) and then irradiated with sterilizing light to filter the filter unit (40). It can sterilize bacteria attached to the.

Bacteria and viruses in the contaminated air flowing into the vehicle's intake are collected by the electrostatic power of the filter unit 40 using a HEPA filter. Additionally, bacteria collected in the filter unit 40 can be removed by irradiation of sterilizing light.
