The photocatalyst applied to the sponge is activated by ultraviolet rays emitted from the LED 154, and radicals and anions generated by the activated photocatalyst decompose various contaminants into water and carbon dioxide. In this way, when the columnar cover 152 is made of a sponge coated with a photocatalyst, it is sterilized by ultraviolet rays radiated while flowing along the side of the sponge, and not only is filtered by passing through the sponge, but also generated by the photocatalyst activated by ultraviolet rays. The effect of decomposing pollutants by radicals and anions can be obtained, allowing the air to be sterilized and purified more effectively.

In another embodiment of the present invention, the columnar cover 152 is made of transparent glass or transparent plastic so that light from each strip LED 154 can be diffused to the peripheral surface.

The polygonal columnar core rod 153 is inserted into the hollow portion of the columnar cover 152 and serves as a support on which each strip LED 154 can be installed. The polygonal column core rod 153 is formed in the shape of a polygonal column, such as a square column, a hexagonal column, or an octagonal column. Each strip LED 154 may be attached to a plane around the polygonal columnar core rod 153.

Each LED 154 emits light that can sterilize the air. In this embodiment, each strip LED 154 may be a UV-C LED module. UV-C LED modules are designed to emit short ultraviolet rays with a wavelength of 200 to 280 nanometers (nm), destroying the surface of objects or bacterial DNA and causing chemical reactions in special substances, which are used in sterilization and curing devices.

Each strip LED 154 is installed on the circumferential surface of the polygonal columnar core rod 153 along the longitudinal direction of the polygonal columnar core rod 153. In one embodiment of the present invention, each strip LED 154 may be a strip LED in which a plurality of LED chips are arranged in the longitudinal direction, as shown in FIG. 8. By being attached along the longitudinal direction of each circumferential surface of the polygonal columnar core rod (153), the LED can radiate ultraviolet rays evenly along the longitudinal direction of the polygonal columnar core rod (153).

The top sterilizer 15 according to an embodiment of the present invention is installed in the inner space of the panel housing 11 between the top particle filter 13 and the fan module 12 disposed at the top of the two fan modules 12. do. In this embodiment, the top sterilizer 15 has a length longer than the width of the top particle filter 13 and can be installed horizontally at the bottom of the top particle filter 13. Accordingly, the flow of air passing through the top particle filter 13 and moving downward by the suction force of the fan module 12 and the longitudinal direction of the top sterilizer 15 are perpendicular to each other, and the top sterilizer 15 is positioned at the top. Since it has a horizontally longer length than the particle filter 13, the air passing through the upper particle filter 13 flows downward along the circumference of the upper sterilizer 15 and is sterilized, and the sterilized air is transferred to the fan module disposed at the top. It is sucked in by (12) and ejected into the car (2).

At this time, if the diameter of the columnar cover 152 is too small, the sterilizing power of the air near the front or rear panel of the air sterilization purification panel 10 may be reduced, and if the diameter of the columnar cover 152 is too large, Since air flow inside the panel housing 11 may not be smooth, the diameter of the column cover 152 must be designed in consideration of the sterilizing performance of the top sterilizer 15.

The top sterilizer (15) can be installed horizontally in the panel housing (11) between the top particle filter (13) and the fan module (12) disposed at the top of the two fan modules (12) in various ways. (11) Can be installed.

In one embodiment of the present invention, the upper sterilizer 15 can be installed by the sterilizer installation plate 151 as shown in Figure 8b. The sterilizer installation plate 151 is formed in the shape of a square plate with a square filter fitting groove 1511 formed in the center, and the left and right ends are located at the rear of the left and right plates of the panel housing 11, respectively, and the rear end This can be coupled to the rear plate of the panel housing (11).

The filter fitting groove 1511 of the sterilizer installation plate 151 has a horizontal length longer than the length of the upper sterilizer 15 and a vertical length shorter than the diameter of the upper sterilizer 15, and the upper sterilizer 15 is installed as a sterilizer. It is coupled by being inserted into the filter fitting groove 1511 of the plate 151 in the horizontal direction. Accordingly, when the upper sterilizer 15 is coupled to the sterilizer installation plate 151 as shown in FIG. 8C, a part of the upper sterilizer 15 is exposed below the sterilizer installation plate 151. Accordingly, sterilization in the downward direction of the sterilizer installation plate 151 is also possible.

In this embodiment, if the thickness of the sterilizer installation plate 151 is too thick, the lower part of the upper sterilizer 15 may not be exposed below the sterilizer installation plate 151, so for better sterilization effect, the sterilizer installation plate ( The thickness of 151) is preferably designed to be the minimum thickness that can stably support the upper sterilizer (15).

The lower sterilizer (16) is installed at the top of the lower air intake port (112) in the panel housing (11) and radiates ultraviolet rays in all directions, which flows into the panel housing (11) through the lower air intake port (112) and moves upward. Sterilizes the air. The bottom sterilizer (16) is the same as the top sterilizer (15) in configuration except that the installation location is different from the top sterilizer (15), so the description of the bottom sterilizer (16) applies mutatis mutandis to the top sterilizer (15).

Meanwhile, in another embodiment of the present invention, it is possible to install only one of the upper sterilizer 15 and the lower sterilizer 16 in the panel housing 11. When only the top sterilizer (15) is installed in the panel housing (11), only the top air intake port (111) is formed on the front plate of the panel housing (11), and only the top particle filter (13) is installed at the location of the top air intake port (111). In the case where only the lower sterilizer 16 is installed in the panel housing 11, only the lower air intake port 112 is formed in the front plate of the panel housing 11, and the lower particle filter 14 is located at the position of the lower air intake port 112. It will be easy for a person skilled in the art to understand that only ) can be installed.

In this way, when only the top sterilizer 15 or the bottom sterilizer 16 is installed in the panel housing 11, the sterilization efficiency may be somewhat reduced, but the top or bottom of the front plate of the panel housing 11 where the air intake is not formed. The bottom space can be used to attach a promotional screen or notification, etc., so the utilization of the air sterilization purification panel 10 can be increased.

The upper sterilizer 15 and the lower sterilizer 16 according to this embodiment are formed in a column shape and are installed to widely contact the air flowing path formed by each fan module 12 within the panel housing 11, thereby forming a panel. The air flowing inside the housing 11 can be sterilized more efficiently.

Figure 9 is a diagram showing the operation of the air sterilization and purification panel 10 according to an embodiment of the present invention. Referring to FIG. 9, the air inside the car 2 passes through the upper air inlet 111 and the lower air inlet 112 formed on the front of the air sterilization purification panel 10 by the suction force of the fan module 12. It is sucked into the air sterilization purification panel (10). At this time, the air that flows into the air sterilization purification panel (10) through the upper air intake port (111) passes through the upper particle filter (13) and enters with foreign substances filtered out, and is sterilized through the lower air intake port (112). The air introduced into the purification panel 10 passes through the bottom particle filter 14 and is introduced with foreign substances filtered out.

The air that flows into the air sterilization and purification panel (10) through the upper air inlet (111) moves downward by the suction force of the two fan modules (12), and passes through the lower air inlet (112) to the air sterilization and purification panel ( The air flowing into the inside of 10) moves upward by the suction force of the two fan modules (12).

The air that flows into the air sterilization purification panel (10) through the upper air intake port (111) and moves downward flows along the circumferential surface of the upper sterilizer (15) and is sterilized by ultraviolet rays emitted in all directions of the upper sterilizer (15). After that, it is sucked into the upper fan module 124 through the suction port formed in the upper fan module 124 disposed below the upper sterilizer 15.

The air that flows into the air sterilization purification panel (10) through the lower air intake port (112) and moves upward flows along the circumferential surface of the lower sterilizer (16) and is sterilized by ultraviolet rays emitted in all directions of the lower sterilizer (16). After that, it is sucked into the lower fan module 125 through the suction port formed in the lower fan module 125 disposed above the lower sterilizer 16.

The sterilized air sucked into the upper fan module 124 and lower fan module 125 is pumped into the car 2 through the sterilized air outlet 113 on the front of the panel housing 11 by each fan module 12. As it is released, sterilized air can be supplied into the car (2).

If one fan module 12 is installed in the air sterilization purification panel 10, the fan module 12 is formed between the upper sterilizer 15 and the lower sterilizer 16, and the upper sterilizer 15 The air sterilized by this passes through the fan module inlet 1235 on the upper surface of the fan module 12, and the air sterilized by the lower sterilizer 16 passes through the fan module inlet 1235 on the lower surface of the fan module 12. A person skilled in the art will easily understand that the air is sucked into the fan module 12 and then discharged into the car 2.

Meanwhile, the air sterilization and purification panels 10 according to an embodiment of the present invention may be installed in a pair in the elevator 1 in diagonal directions. For example, two air sterilization and purification panels 10 may be embedded inside the left side of the rear wall and the right side of the right side wall, respectively. In this way, when the two air sterilization and purification panels 10 are arranged diagonally to each other, a whirlwind may be formed inside the car 2 by the air generated by the fan module 12 of the air sterilization and purification panels 10. Therefore, foreign substances attached to the vehicle can be effectively removed.

More specifically, the air generated by the fan module 12 of one of the pair of air sterilizing and purifying panels 10 and blown out from the sterilizing air outlet 113 is the blown sterilizing air. It moves at a high flow rate near the outlet 113, and the flow rate decreases as you move away from the ejected sterilizing air outlet 113.

As a result, low atmospheric pressure is formed in the space close to the sterilizing air outlet 113 from which the air is ejected due to the rapid movement of air, and in the space far from the sterilizing air outlet 113 from which the air is ejected, the air pressure is formed due to the slow movement of air. As the density increases, high atmospheric pressure is formed. Likewise, the air generated by the fan module 12 of the other air sterilizing and purifying panel 10 among the pair of air sterilizing and purifying panels 10 is blown out from the sterilizing air outlet 113, and thus the air sterilizing air outlet 113 is discharged from the sterilizing air outlet 113. (113) Low air pressure is formed in the nearby space, and high air pressure is formed in the space far from the sterilizing air outlet (113).

In this way, inside the car 1, a low pressure space is formed near the corner where the two sterilizing air outlets 113 are formed, and a high pressure space is formed near the corner where the two sterilizing air outlets 113 are not formed. As air moves from high pressure to low pressure, a whirlwind is formed inside the car 1, and the whirlwind formed in this way can effectively remove dust attached to the vehicle.

In another embodiment of the present invention, two air sterilization and purification panels 10 may be installed on one side wall of the elevator 1. For example, the air sterilization and purification panels 10 may be installed one on each of the left and right sides of the rear wall of the car 2. In this way, when a plurality of air sterilization and purification panels 10 are installed side by side on the same side wall, a stronger air sterilization effect can be provided than when a single air sterilization and purification panel 10 is installed.

The air sterilization and purification panel 10 according to this embodiment is installed embedded in the side wall of the car 2, and each sterilizer 15 and 16, which emits ultraviolet rays in all directions, has a length longer than each air intake port 111 and 112. It is formed in a column shape and is installed horizontally between each air intake port (111, 112) and each fan module (12) within the air sterilization purification panel (10), so that the air sterilization purification panel (10) passes through each air intake port (111, 112). The air flowing inside is sterilized by flowing along the circumferential surface of each sterilizer (15, 16), and the sterilized air is ejected into the car (2) through the fan module (12), effectively purifying the air inside the car (2). It can be sterilized.

In addition, the air sterilization and purification panel 10 according to this embodiment is embedded in the side wall of the car 2 so that the front of the box-shaped air sterilization and purification panel 10 forms part of the inner side wall of the car 2. It does not cause any discomfort to the occupants and does not occupy space inside the car (2).

So far, the present invention has been looked at with a focus on preferred embodiments. A person skilled in the art to which the present invention pertains will understand that the present invention may be implemented in a modified form without departing from the essential characteristics of the present invention. Therefore, the disclosed embodiments should be considered from an illustrative rather than a restrictive perspective. The scope of the present invention is indicated in the claims rather than the foregoing description, and all differences within the equivalent scope should be construed as being included in the present invention.
