Of course, it can be arranged in the target space to see.

Hereinafter, the photocatalytic air conditioning filter module according to an embodiment of the present application will be referred to as the present filter module for convenience of description.

Fig. 1 is a schematic front view of the present filter module, and Fig. 2 is a schematic rear view of the present filter module. In addition, FIG. 3 is a schematic front view for explaining the first cover 30 and the first casing partition 10 of the present filter module, and FIG. 4 is the second casing partition 20 of the present filter module. and a schematic rear view for explaining the second cover 40 . 5 is a schematic cross-sectional view for explaining the staggered arrangement of the first casing partition wall portion 10 and the second casing partition wall portion 20 of the present filter module.

1 to 5 , the present filter module includes a first casing partition wall portion 10 , a second casing partition wall portion 20 , a first cover 30 , and a second cover 40 . In addition, the present filter module may include an active light source (see FIG. 10 exemplarily).

First, in the present filter module, an active light source that activates a photocatalyst in a place (space) where an air flow exists is one of the front side of the first cover 30 and the rear side of the second cover 40 or both front and rear sides described above. (In other words, it may be provided in the form of being disposed on at least one side). For example, this filter module can be used in devices (including air passages) that purify air in spaces such as buildings and transportation means (cars, trains, aircraft, ships, etc.), as well as infectious agents (viruses and bacteria). In various places (spaces) where there is a flow of air contaminated with By providing (30, 40), it may be installed in a form in consideration of air purification efficiency and energy consumption efficiency.

In addition, the flow of air provided to pass through the present filter module may be implemented by various mechanical devices such as a fan, a circulator, and a blower. A mechanical device for causing such a flow of air is apparent to those skilled in the art, and thus a more detailed description thereof will be omitted. In addition, the air flow can be provided without an artificial mechanical device in the present filter module by arranging the present filter module in a target space where the air flow is naturally formed.

The filter module can properly adjust the arrangement direction, installation position, etc. so that the air flow is smoothly formed in the grid-type spaces 12 and 22 and the antiviral function can be effectively implemented. For example, air from the front side of the first casing bulkhead 10 passes through the first and second casing bulkheads 10 and 20 to the second casing bulkhead 20 . A suction-type fan may be disposed on the rear side of the second casing bulkhead 20 so that it can be moved to the rear of the . As a more specific example, the present filter module is disposed in a housing, an inlet through which air is introduced is formed in the housing front member on the front side of the present filter module, and air is sucked into the housing on the rear side of the present filter module to suck air. An air purifying device having an antiviral function to which the present filter module is mounted may be provided in a form in which a suction fan passing through is installed and an outlet for discharging air passing through the filter module is formed on the housing upper surface member. At this time, the air flow inside the housing allows all the air sucked in through the inlet to completely pass through the filter module, and the photocatalyst ball 50 can be effectively activated so that the antiviral function of the filter module can be fully realized. An active light source can be placed where it is located.

10 is a schematic rear view illustrating an embodiment in which an active light source (indicated by a black dot) of the present filter module is disposed behind the second casing partition wall 20 .

The active light source irradiates light toward the photocatalyst balls 50 disposed in the grid-like spaces 12 and 22 , the rear of the second casing partition 20 and the front side of the first casing partition 10 . Alternatively, one or more (one or a plurality) may be disposed on both sides (that is, at least one side) described above. For example, referring to FIG. 10 , one active light source may be disposed (one-to-one correspondence) for each of the present filter modules having the grid-like spaces 12 and 22 of 5×5, but is not limited thereto. The active light source is preferably arranged in a position and number that can further increase the activation efficiency of the photocatalyst ball 50 in consideration of the specifications of the filter module. For example, the active light source irradiates the entire surface of the first casing partition 10 in the form of arranging several light source devices that irradiate a partial surface of the first casing partition 10 in which the photocatalytic ball 50 is accommodated. It can be replaced with a form in which one light source device is arranged. The active light source may be provided in a form installed with respect to the frame structure for mounting the light source (the active light source includes the active light source and the frame structure for mounting the light source). Illustratively, the frame structure for mounting a light source may include a plurality of spacing members disposed at intervals in the vertical or lateral direction and a circumferential member fixing both ends of the plurality of spacing members, and the active light source is the spacing member A plurality of spaced apart along the longitudinal direction of the spacing member with respect to may be installed. In addition, the distance between the spacer members, the thickness of the spacer member, etc. are preferably set appropriately in consideration of the flow of air in the front-rear direction, the structural rigidity of the frame structure for mounting the light source, and the like.

Illustratively, when the active light source is positioned at the rear, the light source mounting structure may be disposed in a form interposed between the second casing partition wall 20 and the second cover 40 , and vice versa, the active light source is positioned at the front When located in the light source mounting structure may be disposed in a form interposed between the first casing partition 10 and the first cover (30). A module form assembled in a single form may be provided through such an inner arrangement of the cover. As another example, when the active light source is located at the rear, the light source mounting structure may be disposed behind the second cover 40, and conversely, when the active light source is located at the front, the light source mounting structure is the first cover ( 30) may be disposed in front of it.

Exemplarily referring to FIG. 10 , the active light source may be disposed behind the second casing partition wall 20 . When the present filter module is implemented in the form of an air purification device disposed inside the housing, the air introduced from the front of the first casing bulkhead 10 and passed to the second casing bulkhead 20 and moved backward is Until it is discharged through the air outlet provided on the upper side or rear (rear) side of the housing, the air flow direction may not be uniformly formed due to the differential pressure, and a vortex may be formed. That is, since a vortex is formed by the differential pressure in the space behind the second casing partition 10 through which the air has passed, in the case of the photocatalyst ball 50 accommodated in the second casing partition 10, the air due to the vortex Since the beneficial effect of the photocatalytic activity can be more effectively expressed as the contact surface with the ray is widened or the contact time is prolonged, the active light source may be disposed at the rear of the second casing partition wall 20 in consideration of this point. However, the arrangement position of the active light source is not necessarily limited thereto, and may be set to a position capable of excellent air purification ability and energy consumption reduction.

In addition, the light irradiated to the photocatalyst ball 50 from the active light source of the present filter module may be light having a characteristic capable of activating the photocatalyst. Although it is preferable to set the characteristics of the light in consideration of the characteristics of the photocatalytic material included in the photocatalytic ball 50, for example, the light may be light including a wavelength in the ultraviolet region. For example, the light of the active light source may be irradiated with light having a wavelength of 200 nm to 390 nm, which is the wavelength of ultraviolet light, but is not limited thereto, and is set to light including a wavelength having the highest photocatalytic activation efficiency. It would be desirable Illustratively, the photocatalytic material included in the photocatalytic ball 50 may include titanium dioxide, and the light irradiated from the active light source maximizes the photocatalytic activation efficiency of this titanium dioxide and does not generate ozone from 360 nm to 380 nm It may be set to ultraviolet light in a wavelength band. However, in the present application, the photocatalyst is not necessarily limited to titanium dioxide, and known photocatalysts and various photocatalysts developed in the future may be applied to the present application. In addition, since the reaction between the light and the photocatalyst is obvious to those skilled in the art, a detailed description thereof will be omitted.

In addition, the present filter module includes a guide frame to secure a separation distance between the active light source and the photocatalyst ball 50 and an air flow path, and a light reflection plate to minimize external leakage of light irradiated from the active light source and maximize photocatalytic activation efficiency. , an active light source driver and a power supply line.

For example, when the active light source of the present filter module is a UV LED having a light irradiation angle of 120 degrees, light can be irradiated up to a range of 40 mm when a distance of 10 mm is given. However, in consideration of the light irradiation angle of the active light source, the light amount deviation, etc., the separation distance between the active light source and the photocatalyst ball 50 in consideration of the aspect of increasing the photocatalytic activity of the photocatalyst ball 50 and the aspect of securing energy efficiency And it is preferable to set the number of active light sources, an interval between the active light sources, and the like.

In addition, the light reflection plate reflects the light that has passed through the first and second casing partition walls 10 and 20 or the light scattered from the casing partition walls 10 and 20 in the direction of the active light source to the first and second casings again. It may be disposed at a position opposite to or adjacent to the active light source so as to be reflected toward the partition walls 10 and 20 . Illustratively, when the active light source is located at the rear in order to reflect the light passing through the first and second casing barrier ribs 10 and 20 back to the barrier ribs 10 and 20, the light reflecting plate is the first casing It may be located in the front of the jing bulkhead part 10 , and conversely, when the active light source part is located in the front, the light reflection plate may be located in the rear of the second casing partition wall part 20 . In addition, in order to reflect the light scattered from the first and second casing barrier ribs 10 and 20 in the direction of the active light source back to the casing barrier rib, when the active light source is located in front, the light reflection plate is located in front of the active light source Alternatively, when the active light source unit is located at the rear, the light reflection plate may be located at the rear of the active light source unit.

The active light source irradiates light toward the photocatalyst balls 50 disposed in the grid-like spaces 12 and 22 , the rear of the second casing partition 20 and the front side of the first casing partition 10 . Alternatively, one or more (one or a plurality) may be disposed on both sides (that is, at least one side) described above.

In addition, the light reflection plate may be provided to have a surface material capable of reflecting light. In addition, the light reflection plate preferably has a structure partially opened in the front-rear direction so that the flow (flow) of air in the front-rear direction is not restricted. For example, the light reflection plate may be provided to have a pattern corresponding to each of the first and second casing partition walls 10 and 20 lattice space. As a more specific example, the light reflecting plate may include a reflective pattern unit for reflecting the arriving light and an opening pattern unit for passing the reached air. At this time, the reflective pattern portion is provided in a material, standard, and shape that can have a reflection angle, reflectance, etc. that can more efficiently reflect the light reaching it toward the first and second casing barrier rib portions 10 and 20. desirable.

Illustratively, when the active light source unit is positioned in front in order to reflect the light passing through the first and second casing partition walls 10 and 20 back toward the casing partition walls 10 and 20, the light reflection plate is 2 It may be disposed between the casing partition wall 20 and the second cover 40 or in a form interposed behind the second cover 40, on the contrary, when the active light source unit is located at the rear, the light reflecting plate is the first casing It may be disposed between the bulkhead portion 10 and the first cover 30 or interposed in front of the first cover 30 . As another example, in order to reflect the light scattered from the first and second casing barrier ribs 10 and 20 in the direction of the active light source back to the casing barrier ribs 10 and 20, when the active light source is positioned in front, light The reflecting plate may be disposed in a form interposed in front of the active light source unit, and conversely, when the active light source unit is located in the rear, the light reflecting plate may be disposed in a form interposed in the rear of the active light source unit. When the light reflecting plate is disposed inside the cover, the light reflecting plate, the cover, and the casing barrier rib may be provided in a module form assembled in a single form. (including the active light source and the frame structure for mounting the light source) may be provided in the form of a module assembled into a single form.

Since the active light source driver and the power supply line are obvious to those skilled in the art, a more detailed description thereof will be omitted.

On the other hand, referring to FIGS. 1 to 5 , the photocatalyst ball 50 is formed in the lattice-shaped spaces 12 and 22 (up and down) of the first casing partition wall portion 10 and the second casing partition wall portion 20 of the present filter module. It can be accommodated in the partition wall inner space formed by the partition walls located on the left and right, respectively. In addition, the photocatalyst ball 50 itself may be a ball made of a material containing a photocatalyst material, or a ball in which a photocatalyst is coated on a ball shape of another material (eg, ceramic or metal material). In the case of a ball coated with a photocatalyst, various coating methods known in the prior art or to be developed in the future may be applied and provided.

In addition, the size of the diameter of the photocatalyst ball 50 can be adjusted. For example, in order to improve air purification performance by increasing air circulation efficiency, the size (diameter) of the photocatalyst ball 50 is the size (width or height) inside the lattice space 12 and 22 of the partition wall part, which will be described later. By setting it smaller, it is possible to induce a smoother air flow in the air flow. That is, the lattice-shaped space 12 or the second K of the first casing partition wall part 10 so that the photocatalyst ball 50 can flow in the lattice-shaped spaces 12 and 22 accommodated in response to the flow of air. By being provided smaller than the size of the grid space 22 of the gong partition 20, the air flow may also be smoother according to the flow of the photocatalyst ball 50. On the other hand, in order to improve the air purification performance by increasing the one-pass performance, the size (diameter) of the photocatalyst ball 50 is set to be similar to the size inside the partition lattice space 12, 22, which will be described later, so that the photocatalyst By providing the balls 50 densely, it is possible to induce the flowing air to contact the surface of the photocatalyst balls 50 as much as possible.

In addition, the photocatalyst ball 50 is accommodated in one or more (one or a plurality) in one grid-type space (12, 22), to flow in the grid-type space (12, 22) accommodated in response to the flow of air. In order to be able to do this, an allowance may be formed with respect to at least one of the horizontal and vertical directions of the grid-type spaces 12 and 22 in a state where one or more (one or a plurality) are accommodated in the grid-type spaces 12 and 22 . It may be provided in any size.

For example, when one photocatalyst ball 50 is accommodated in one grid-type space 12 and 22 in a one-to-one correspondence between the photocatalyst ball 50 and the grid-type spaces 12 and 22 (one grid-type space) When one photocatalyst ball 50 is accommodated in the spaces 12 and 22), one photocatalyst ball 50 is accommodated in one grid-shaped space 12, 22, and the photocatalyst ball 50 is In order to be able to flow in the lattice-shaped spaces 12 and 22 accommodated in response to the flow, the photocatalytic ball 50 is formed in the lattice-shaped space 12 of the first casing partition 10 or the second casing partition wall portion. (20) may be provided smaller than the size of the grid space (22). In this case, the first cover 30 and the second cover 40 may be provided to allow air to pass through but to prevent the photocatalyst ball 50 from being separated.

In addition, when a plurality of (N) photocatalyst balls 50 are accommodated in one lattice space 12 and 22 in a many-to-one correspondence between the photocatalyst balls 50 and the lattice-shaped spaces 12 and 22, the photocatalyst balls A plurality of 50 is accommodated in one grid-type space 12, 22, so that the photocatalyst ball 50 can flow in the grid-type space 12, 22 accommodated in response to the flow of air, the grid type In a state in which a plurality of spaces 12 and 22 are accommodated, the lattice-shaped spaces 12 and 22 may be provided with a size capable of forming a clearance with respect to at least one of a horizontal direction and a vertical direction. In this case, the first cover 30 and the second cover 40 may be provided to allow air to pass through but to prevent the photocatalyst ball 50 from being separated.

In addition, the photocatalyst ball 50 may be provided to have a uniform (constant) diameter. For example, the inner size (width or height) of the grid-type spaces 12 and 22 may be 4.5 mm, and the diameter of the photocatalytic ball 50 may be about 4 mm, but is not necessarily limited thereto, and the size of the differential pressure; It can be set in consideration of air purification ability and energy consumption efficiency.

As described above, in the present application, air circulation efficiency or one-pass performance can be adjusted by adjusting the size (width or height) of the inside of the lattice-shaped spaces 12 and 22 of the bulkhead. That is, the size (width or height) of the grid-type space 12 of the first casing partition 10 or the grid-type space 22 of the second casing partition 20 is larger than the diameter of the photocatalyst ball 50 . By setting it large (for example, the inner size (width or height) of the grid-like spaces 12 and 22 is 14 mm, and the diameter of the photocatalyst ball 50 is about 10 mm), the air flow is smoother in the air flow. It can induce the photocatalyst ball 50 to contact the air including the infectious agent (virus or bacteria) as much as possible (a method of improving air purification performance by increasing air circulation efficiency), unlike the first The size (width or height) of the grid space 12 of the casing partition 10 or the grid space 22 of the second casing partition 20 is the size (diameter) of the photocatalyst ball 50 and By setting similarly (for example, the internal size (width or height) of the grid-like spaces 12 and 22 is 4.5 mm, and the diameter of the photocatalyst ball 50 is about 4 mm), the photocatalyst ball 50 is air It can induce maximum contact with infectious agents (viruses or bacteria) in the air flowing along it (a method of improving air purification performance by increasing one-pass performance).

In addition, the separation distance between the photocatalyst ball 50 and the partition wall to be described later may be set in consideration of the size of the differential pressure according to the flow of air, air purification ability, energy consumption efficiency, and the like.

On the other hand, the first casing partition 10 has a configuration in which a plurality of spaces (lattice-shaped spaces) 12 in which the above-described photocatalyst balls 50 can be located are provided in a lattice shape. For example, the first casing bulkhead 10 may be provided in the form of an insect screen (mesh or lattice form). It is preferable that the first casing partition wall portion 10 is provided to have a thickness in the front-rear direction sufficient to accommodate the photocatalyst ball 50 . Referring to FIG. 5 , the first casing barrier rib 10 may be disposed relatively forward than the second casing barrier rib 20 .

Also, referring to FIGS. 1 and 3 , the first casing partition wall 10 may be disposed behind the first cover 30 . Illustratively, the first casing partition 10 may be coupled (connected) to the first cover 30 through a fastening means such as screw coupling. However, the fastening method between the first casing bulkhead portion 10 and the first cover 30 disposed in front thereof is not limited to only screw coupling, and various known fastening methods may be applied. Illustratively, the first casing bulkhead 10 may be provided in a shape having a rectangular outline when viewed from the front. In addition, the lattice-shaped space 12 formed in the first casing partition wall portion 10 for accommodating the photocatalytic ball 50 may be provided as a space having a rectangular outline when viewed from the front.

Illustratively, the manufacturing method of the first casing bulkhead 10 may include an injection mold, a press mold, laser cutting, water jet, and the like, but is not limited thereto.

For reference, FIG. 13 is a view for explaining an example of a method of manufacturing the first casing partition wall portion 10 or the second casing partition wall portion 20 of the present filter module. Referring to FIG. 13 , the partition wall of the first casing partition 10 is formed by separately manufacturing a horizontal partition wall and a vertical partition wall, and a cutout cut in the front and rear direction is formed in each of the horizontal partition wall and the vertical partition wall. The horizontal partition wall and the vertical partition wall may be coupled to each other by a fitting method for the . Illustratively, any one of the horizontal partition wall and the vertical partition wall has a cutout recessed from the front to the rear, and the other has a cutout recessed from the rear to the front side, so that these cutouts are opposite to each other. A partition wall may be coupled.

Accordingly, each of the first casing partition wall 10 and the second casing partition wall 20 may include a horizontal partition wall and a vertical partition wall. Also, referring to FIG. 13 , a first cutout recessed from the front to the rear is formed in one of the horizontal partition wall and the vertical partition wall, and the other one of the horizontal partition wall and the vertical partition wall is depressed from the rear to the front to match the first cutout. A physical second cutout may be formed, and the horizontal partition wall and the vertical partition wall may be coupled to each other by engaging the first cutout and the second cutout. Specifically, the first cutout and the second cutout are to be joined by engaging the rear end of the first cutout (the deepest recessed portion of the first cutout) and the front end of the second cutout (the deepest recessed portion of the second cutout). can

The thickness of the barrier rib may be about 0.1 mm to 1.2 mm, and more preferably 0.5 mm to 1.0 mm. If the barrier rib is too thick, the differential pressure increases and the amount of air flow is reduced, which is undesirable. If it is too thin, it may be difficult to obtain rigidity to maintain the shape. However, the present invention is not limited thereto, and may be determined in consideration of material, air purification capability, cost, and the like.

On the other hand, the first cover 30 covers the front surface of the first casing partition wall portion 10 to prevent the photocatalyst ball 50 accommodated in the grid space 12 of the first casing partition wall portion 10 from escaping. As a configuration to, it may be disposed in front of the first casing partition wall (10). Referring to FIG. 3 , the first cover 30 is a ball separation preventing member 31 extending to cross the middle (eg, the center) of the grid space 12 of the first casing partition 10 . may include. Illustratively, the ball departure preventing member 31 may be a plurality of members extending in the vertical direction and disposed at intervals in the horizontal direction, but is not limited thereto. As another example, the ball departure preventing member 31 may be a member extending in the horizontal direction or a member in the form of a mesh extending in the horizontal direction and also extending in the vertical direction. In addition, the arrangement interval of the ball separation preventing member 31 may be set to a distance capable of preventing separation of the photocatalyst balls 50 in consideration of the size (diameter) of the photocatalyst balls 50 . For example, when the size of the photocatalyst ball 50 is significantly smaller than the internal size of the grid-type space 12 , a plurality of ball separation preventing members 31 are arranged to cross one grid-type space 12 . it could be In addition, a plurality of photocatalyst balls 50 having a small diameter may be placed in one lattice space 12 and covered with a mesh-shaped cover to be fixed.

In addition, as described above, the first casing bulkhead portion 10 may be coupled to each other through a fastening means such as screw coupling. Illustratively, the fastening means includes a long screw capable of connecting the first cover 30 , the first casing bulkhead 10 , the second casing bulkhead 20 and the second cover 40 at once. can do. However, the present invention is not limited thereto, and various types of fastening means known in the prior art or developed in the future may be applied to the fastening means. It goes without saying that the same can be applied to the fastening means to be described later.

On the other hand, the second casing bulkhead part 20 is coupled to the rear end of the first casing bulkhead part 10 , and is a lattice type positioned to cross the lattice space 12 of the first casing bulkhead part 10 . It is a configuration in which a plurality of spaces 22 are provided. The second casing bulkhead 20 may be provided by the same or similar material and manufacturing method as the first casing bulkhead 10, and adjacent components (first k Since it can be connected to the gong bulkhead part 10 and the second cover 40), the difference from the first casing bulkhead part 10 will be mainly described, and the contents already described in the first casing bulkhead part 10 and A detailed description of the content that can be understood with reference to the drawings will be omitted.

6 is a schematic front view for explaining the staggered arrangement of the first casing partition wall portion 10 and the second casing partition wall portion 20 of the present filter module, and FIG. 7 is the first casing partition wall portion of the present filter module. It is a conceptual diagram for explaining the staggered arrangement of the part 10 and the second casing partition wall part 20 .

5 to 7 , the second casing bulkhead part 20 is overlapped with the first casing bulkhead part 10 at the rear of the first casing bulkhead part 10 in a staggered state with respect to the front-rear direction. can be stacked. This staggered overlap takes into account the flow of air passing over the surface of the photocatalyst ball 50 accommodated in the first casing partition 10 and the photocatalyst ball 50 accommodated in the second casing partition 20, This is so that the contact area in which the air passing through the filter module comes into contact with the photocatalyst ball 50 can be increased. Therefore, it is preferable to set the overlapping degree in consideration of the degree of rear differential pressure generation according to the flow of air passing through the filter module, the air purification ability according to the photocatalytic activation reaction, energy consumption efficiency, etc. .

More specifically, referring to FIGS. 5 to 7 (mainly FIG. 6) together, the staggered arrangement of the first casing partition wall portion 10 and the second casing partition wall portion 20 means the front (front) or rear When viewed from (rear side), the partition wall of the first casing partition wall portion 10 crosses the middle of the grid-like space 22 of the second casing partition wall portion 20, and on the contrary, the second casing partition wall portion 20 ) means that the barrier ribs are arranged to cross the middle of the lattice space 12 of the first casing barrier rib 10, so that the barrier ribs do not coincide with each other and are displaced (spaced apart in the lateral direction). This may be clearly understood through the matters shown in FIGS. 5 to 7 .

8 shows the size of the photocatalyst ball 50, the size of the grid space, the thickness of the partition wall, etc. when the first casing partition wall part 10 and the second casing partition wall part 20 of the present filter module are alternately arranged according to the settings The degree or amount of space (space) formed between the photocatalyst ball 50 accommodated in the first casing partition wall 10 and the photocatalyst ball 50 accommodated in the second casing partition wall 20 when viewed from the front It is a conceptual diagram for explaining the degree to which the photocatalyst balls 50 overlap each other. In addition, FIG. 9 is a view showing an example of a design for considering the arrangement area according to the arrangement of the photocatalyst balls 50 . Referring to FIG. 8 by way of example, in order to purify the air in a way to increase the one-pass performance, the photocatalyst balls 50 with a diameter of 4 mm are confined in the grid-type spaces 12 and 22 at intervals of 4.5 mm. As described above, when the grid-type spaces 12 and 22 are alternately arranged, the photocatalyst ball 50 of the first casing partition 10 and the adjacent second casing partition 20 when viewed from the front ), the maximum separation distance (s) between the photocatalyst balls 50 may be 0.2426mm (referring to FIG. 8 , the photocatalyst balls 50 in the grid-type spaces 12 and 22 are moved to the upper left or lower right as far as possible). The separation distance in the state of being in close contact with each other is considered as the maximum separation distance). As such, when the spacing between the partition walls is arranged in a space of 4.5 mm to confine the photocatalyst balls 50 having a diameter of 4 mm, due to the formation of the space (separation distance (s)) according to the spacing 0.2426 mm, the photocatalyst balls 50 are It can be seen that even if arranged in two stages, there is a possibility that the air passing through it may pass without contacting the photocatalyst ball 50 . Therefore, it is necessary to set the optimal separation distance between the photocatalyst balls 50 in consideration of the flow rate of air and the level of contact with the photocatalyst balls 50 through experiments and simulations (see FIG. 9 ).

Accordingly, the first casing partition wall portion 10 , the second casing partition wall portion 20 , and the photocatalyst ball 50 are first disposed in the lattice space 12 of the first casing partition wall portion 10 . The photocatalyst ball 50 and the grid-type space 12 of the first casing partition 10 and the grid-type space 22 of the second casing partition 20 that are adjacent to each other in a form partially overlapping in the front-rear direction ), even if the second photocatalyst balls 50 are spaced apart as far as possible from each other, the first photocatalyst ball 50 and the second photocatalyst ball 50 may partially overlap when viewed from the front or rear. .

For example, the first casing barrier rib part 10 , the second casing barrier rib part 20 and the photocatalyst ball 50 may include at least one of the first photocatalyst ball 50 and the second photocatalyst ball 50 . Even if the center and the center of the grid space 12 and 22 in which it is accommodated have positions that do not coincide, the first photocatalyst ball 50 and the second photocatalyst ball 50 partially overlap when viewed from the front or rear, In other words, it may be provided so that a separation distance s is not formed between the first photocatalyst ball 50 and the second photocatalyst ball 50 . Accordingly, the possibility that the air passes without contacting the photocatalyst ball 50 may be reduced.

In addition, the plurality of lattice-shaped spaces 22 of the second casing barrier rib 20 includes a photocatalyst ball (second photocatalyst ball) 50 accommodated therein and a plurality of the first casing barrier ribs 10 . Between the photocatalyst balls (first photocatalyst balls) 50 accommodated in each of the lattice-shaped spaces 12, a plurality of first casing partition walls 10 are formed so that a separation distance is not formed in each diagonal direction. Each of the lattice-shaped spaces 12 may be alternately positioned. In other words, the first casing partition wall portion 10 , the second casing partition wall portion 20 , and the photocatalyst ball 50 are formed between the first photocatalyst ball 50 and the second photocatalyst ball 50 in the diagonal direction. It may be provided so that the separation distance (s) is not formed.

For reference, referring to FIG. 8 , spaced apart in the diagonal direction here is a grid-type space 12 of the first casing partition 10 and a grid-type space 22 of the second casing partition 20 . ) are alternately disposed in the horizontal and vertical directions, the first photocatalytic ball 50 and the second casing partition 20 disposed in the lattice space 12 of the first casing partition 10 . It may mean that the second photocatalyst balls 50 disposed in the grid space 22 are spaced apart as far as possible.

In the case of this filter module, it is necessary to select materials and modularize parts in consideration of filter performance optimization and mass production. In particular, the degree of differential pressure, air purification efficiency (one pass, air circulation, etc.), energy It is necessary to manufacture in consideration of consumption efficiency, etc.

In addition, referring to FIGS. 4 (a), 5 and 6 (b), the second casing bulkhead part 20 is connected to at least one of the upper, lower, left, and right bulkheads forming the grid-like space 22 . A hole 21 through which air communicates with the adjacent grid space 22 may be formed through hole processing or the like. Therefore, the air flowing in from the front and passing through the grid-type spaces 12 and 22 of the filter module casing bulkheads 10 and 20 can form a vortex in the closed space except for the air outlet at the rear. and, accordingly, since air rotation can be generated at the rear of the second casing bulkhead 20, the grid type of the second casing bulkhead 20 to make the air flow more smoothly due to the generation of such a rear vortex. A hole 21 may be formed in the partition wall forming the space 22 . The air moved to the specific grid-type space 22 by the hole 21 is re-moved to the adjacent grid-type space 22 through the hole, thereby reducing the pressure differential and at the same time, the contact area for the photocatalyst ball 50 It can also be increased. One or more holes 21 may be formed in one partition wall in consideration of air flow efficiency.

Meanwhile, referring to FIGS. 2 and 4 , the second cover 40 covers the rear surface of the second casing partition wall 20 and accommodates the photocatalyst in the grid space 22 of the second casing partition wall 20 . It is a configuration that prevents the ball 50 from coming out. Since the second cover 40 may be understood as the same or similar to the first cover 30 with reference to the drawings, overlapping descriptions such as the ball separation preventing member 41 and the fastening means will be omitted.
