Description

Technology Field

[0001] The present invention relates to an air purification device equipped with a filter element capable of sterilization, and more specifically, to an air purification device capable of effectively removing viruses and pathogens inhabiting the filter element by forming a UV sterilization device on the filter element installed inside the air purification device. Background Technology

[0003] Generally, recently constructed buildings utilize air purification devices (air conditioning systems) that forcibly draw in and exhaust indoor and outdoor air through ventilation fans and enable air purification and energy saving using filter elements and heat exchange elements. The aforementioned building air purification devices are typically installed on the ceiling for efficient space utilization and draw in and exhaust indoor and outdoor air through ducts.

[0004] In addition, these conventional air conditioning devices enhance dust collection capabilities by allowing air intake and exhaust to occur through a filter element embedded in the middle of the case.

[0005] Dust adheres to the surface of these filter elements, but also accumulates inside. Since this accumulated dust contains or harbors viruses, bacteria, and pathogens harmful to the human body, it results in poor air quality and poses a risk to the health of residents.

[0006] However, the problem is that it is not easy to remove viruses, bacteria, and pathogens that inhabit or exist inside conventional filter elements.

[0007] Of course, devices for sterilizing filter elements by installing an ultraviolet (UV) lamp on one side of the filter element have been disclosed in the past. Specifically, as disclosed in Public Patent No. 10-2008-0108172, a photocatalytic UV reactor filter element for air purification to improve air quality is configured by installing a 254nm UV lamp layer and a 365nm UV lamp layer alternately between a photocatalytic nonwoven fabric filter element layer, and as disclosed in Registered Patent No. 10-2353450, a humidifying filter element assembly has been developed to install a UV LED to activate the filter element on one side of the filter element and to rotate the filter element to receive ultraviolet light.

[0008] However, the former has the disadvantage of increasing manufacturing costs because it requires a large number of UV lamps, as multiple UV lamps are installed in parallel in an alternating manner, and the latter has the disadvantage of being difficult to manufacture because it uses only one UV LED device but has a structure that requires rotating the filter element.

[0018] In another embodiment of the present invention, the UV light lifting and lowering means is characterized by being composed of a towing rope connected to one side of the UV light, a drive shaft for winding the towing rope, and a motor for rotating the drive shaft.

[0019] In another embodiment of the present invention, the UV lighting lifting and lowering means is characterized by comprising a screen that is lifted and lowered while in close contact with the side of a filter element and equipped with a UV light at the bottom, a drive shaft for winding the screen, a motor for rotating the drive shaft, and a horizontal through hole formed in the lower part of the screen. Effects of the invention

[0021] The effects of the present invention as described above include having a structure in which a UV light can move up and down while illuminating the side of a filter element in close contact with the side of the filter element provided inside the air purification device, thereby not causing structural changes to the filter element, and in the sterilization mode during operation, the UV light moves up and down and irradiates the filter with strong ultraviolet rays, so that viruses and pathogens present inside and outside the filter element can be effectively eradicated, and in the cleaning mode during operation, a strong airflow is formed through a narrow horizontal opening, thereby enabling cleaning of the inside of the filter element.

[0022] As such, the present invention is a very useful invention that forms both through holes and UV lights in a screen without interfering with each other, allows for combined filter cleaning and sterilization, and minimizes manufacturing costs due to its simple structure.

[0028] Hereinafter, a preferred embodiment of an air purification device having a sterilizable filter element according to the present invention will be described in detail with reference to the attached drawings.

[0030] First, it should be noted that identical components or parts in the drawings are indicated by the same reference numerals whenever possible. Additionally, in describing the present invention, specific descriptions of related known functions or configurations are omitted to avoid obscuring the essence of the invention.

[0031] The air purification device of the present invention is configured such that a blower fan (B) is provided inside a case (A) to enable the intake and discharge of air, and dust in the air is filtered by a filter element (20), and a UV light (30) is installed to be able to move up and down while illuminating the side of the filter element (20) in a state of close contact with the side of the filter element (20), and a UV light raising and lowering means is installed on the upper side of the filter element (20) to raise and lower the UV light (30).

[0032] The above-described UV light lifting and lowering means consists of a traction line (40) connected to one side of the UV light (30), a drive shaft (12) for winding the traction line (40), and a motor (11) for rotating the drive shaft (12). At this time, it is preferable to form reels (51) on both sides of the drive shaft (12) to make the winding of the traction line (40) more stable.

[0033] The above UV lighting (30) refers to ultraviolet lighting having a wavelength range capable of sterilization, and it is preferable to install LED lamps (30a) in two rows vertically, but to install them in a zigzag pattern. This is because, in the case of LED lamps (30a), the irradiation direction is a straight line, and due to the characteristics of the UV lighting (30) of the present invention which moves up and down at narrow intervals, the sterilization range may be narrow. Therefore, LED lamps (30a) that have a stronger sterilization effect should be used, and the irradiation direction should be arranged to cover multiple directions.

[0034] In addition, as another embodiment of the present invention, a UV lighting lifting and lowering means having the following structure may be configured to allow sterilization and internal cleaning of the filter element (20) to be performed simultaneously.

[0035] That is, it consists of a screen (50) that moves up and down in close contact with the side of the filter element (20), a UV light (30) coupled to the bottom of the screen (50), a drive shaft (12) for winding the screen (50), a motor (11) for rotating the drive shaft (12), and a narrow horizontal through hole (51) formed at the bottom of the screen (50). The through hole (51) is a means to allow wind to pass through only a part of the filter element (20). At this time, it is preferable that the through hole (13) be formed in a horizontal direction, because the airflow formed by the blower must proceed in a straight line so that the filter element (20) can be cleaned thoroughly.

[0036] In this structure, the UV light (30) acts as a weight to provide weight to the bottom of the screen (50) when the screen (50) is raised and lowered, thereby enabling stable raising and lowering.

[0037] In the present invention, the screen (50) refers to a fabric that does not allow wind to pass through, and must be able to block other parts of the filter element (20) except for the through hole (51). To this end, it is preferable that the lower part of the screen (50) be foldable.

[0038] The reason the lower part of the screen (12) must be folded or wound is that when the through hole (13) of the screen (12) rises upward, the airflow to other parts of the filter element (20) must be blocked by the lower screen (12). At this time, the lower part of the screen (12) must be folded so that space can be utilized efficiently.

[0039] It is preferable that the above-mentioned through hole (51) be formed such that its vertical length is shorter than its horizontal length in the horizontal direction of the filter element (20), so that the interior of the filter element (20) can be cleaned sequentially from the bottom to the top by a strong wind. Accordingly, a blower (capable of generating a strong wind) capable of generating a strong wind is provided on one side of the filter element (20). B ) becomes necessary.

[0040] Therefore, when the blower (B) is operated with the through hole (51) of the screen (50) positioned at the bottom of the filter element (20), the screen (50) is pressed against one side of the filter element (20) by the air pressure. Then, when the motor (11) is operated to drive the rotation of the drive shaft (12) and the screen (50) is wound, the through hole (51) located at the bottom of the filter element (20) rises gradually. While other parts of the screen (50) block air from passing into the filter element (20), the through hole (51) is open, allowing a stronger airflow to pass through, thereby enabling cleaning from the bottom to the top of the filter element (20). Additionally, the UV light (30) located directly below the through hole (51) also rises along the screen (50), allowing for sterilization of the filter element (20) to be performed in parallel.

[0041] As such, the present invention proposes the optimal structure that effectively performs cleaning and sterilization while minimizing manufacturing and maintenance costs without making significant changes to the filter structure, and is a structure that can be easily installed in existing air conditioning systems.

[0043] As described above, although the present invention has been explained by limited embodiments, the present invention is not limited thereto, and various modifications and variations are possible within the scope of the technical spirit of the present invention and the equivalent scope of the patent claims described below by those skilled in the art to which the present invention belongs.
