DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] Hereinafter, the embodiments of the present application will be described in detail with reference to the accompanying drawings so that a person skilled in the art to which the present application pertains can easily carry out the present application. However, the present application may be embodied in various different forms and is not limited to the embodiments described herein. In order to clearly explain the present application in the drawings, parts that are not related to the description are omitted, and similar parts are designated by similar reference numerals throughout the specification.

[0027] Throughout this specification, when a part is said to be "connected" to another part, this includes not only "directly connected" but also "electrically connected" or "indirectly connected" with another element therebetween.

[0028] Throughout this specification, when an element is referred to as being "on," "upper," "top," "upper end," "under," "lower," or "bottom" of another element, this includes not only when the element is in contact with the other element, but also when there is another element between the two elements.

[0029] Throughout this specification, when a part "comprises" a certain element, this means that it can further include other elements, rather than excluding other elements, unless specifically stated to the contrary.

[0030] In the entire specification, the front view and the back view are indicated based on the drawings, and the direction of the photocatalytic air-conditioning filter module according to an embodiment of the present application is not limited thereto. For example, based on the drawings, the photocatalytic air-conditioning filter module according to an embodiment of the present application can be arranged so that its front face faces upward or in an oblique direction, and of course, it can be arranged in the target space so that it faces in various directions in consideration of the direction in which the module needs to be arranged.

[0031] Hereinafter, for convenience of explanation, the photocatalytic air-conditioning filter module according to one embodiment of the present application will be referred to as the present filter module.

[0032] Fig. 1 is a schematic front view of the filter module, and Fig. 2 is a schematic rear view of the filter module. Fig. 3 is a schematic front view for explaining the first casing partition wall portion 30 and the first casing partition wall portion 10 of the filter module, and Fig. 4 is a schematic rear view for explaining the second casing partition wall portion 20 and the second lid 40 of the filter module. Fig. 5 is a schematic cross-sectional view for explaining the alternating arrangement of the first casing partition wall portion 10 and the second casing partition wall portion 20 of the filter module.

[0033] 1 to 5, the filter module includes a first casing partition part 10, a second casing partition part 20, a first lid 30, and a second lid 40. The filter module may also include an active light source (see FIG. 10 for example).

[0034] First, the filter module may be provided in a form in which an active light source for activating a photocatalyst is disposed in a place (space) where air flow exists, on one of the front side of the first cover 30 and the rear side of the second cover 40, or on both the front and rear sides (i.e., at least one side). For example, the filter module may be installed in various places (spaces) including the inside (including the air passage) of a device for purifying air in a space such as a building or a means of transportation (car, train, airplane, ship, etc.) where air flow contaminated with an infectious source (virus and bacteria) exists and beneficial effects due to photocatalyst activity such as performance of anti-virus function and air purification are required, by including the active light source, casing partitions 10, 20, and covers 30, 40, in consideration of air purification efficiency and energy consumption efficiency.

[0035] In addition, the air flow provided to pass through the present filter module may be realized by various mechanical devices such as a fan, a circulator, a blower, etc. A detailed description of the mechanical devices that induce such air flow will be omitted since they are obvious to those skilled in the art. In addition, the air flow can be provided without the need for an artificial mechanical device by disposing the present filter module in a target space where an air flow is naturally formed.

[0036] The present filter module can be appropriately adjusted in its arrangement direction and installation position so that the air flow is smoothly formed as the lattice-type spaces 12 and 22, and the anti-virus function can be effectively realized. For example, an intake type fan can be disposed on the rear side of the second casing partition wall part 20 so that the air on the front side of the first casing partition wall part 10 can pass through the first casing partition wall part 10 and the second casing partition wall part 20 and move to the rear of the second casing partition wall part 20. As a more specific example, an air purifying device having an anti-virus function in which the present filter module is mounted may be provided, in which the present filter module is disposed in a housing, an inlet through which air flows is formed in a front member of the housing on the front side of the present filter module, an intake fan is installed inside the housing on the rear side of the present filter module to draw in air and pass it through the present filter module, and an outlet is formed in a top member of the housing to discharge the air that has passed through the present filter module. At this time, the air flow inside the housing allows all air drawn in through the inlet to pass completely through the filter module, and the active light source can be disposed at a position where the photocatalyst balls 50 can be effectively activated so that the anti-virus function of the filter module can be fully realized.

[0037] FIG. 10 is a schematic rear view showing an embodiment in which the active light source (represented by a black dot) of the filter module is disposed behind the second casing partition 20. As shown in FIG.

[0038] The active light source may be arranged at least one (one or a plurality of) at the rear of the second casing partition 20 and at one front side of the first casing partition 10 or at both front and rear sides (i.e., at least one side) so as to irradiate light toward the photocatalyst balls 50 arranged in the lattice-type spaces 12 and 22. For example, referring to FIG. 10, one active light source may be arranged (one-to-one corresponding arrangement) per present filter module having 5×5 lattice-type spaces 12 and 22, but is not limited thereto. It is preferable that the active light source is arranged at a position and number that can further increase the activation efficiency of the photocatalyst balls 50 in consideration of the specifications of the present filter module. For example, the active light source may be arranged in a form in which several light source devices are arranged to irradiate a part of the first casing partition 10 in which the photocatalyst balls 50 are accommodated, to a form in which one light source device is arranged to irradiate the front surface of the first casing partition 10. The active light source may be provided in a form installed relative to a frame structure for mounting a light source (the active light source unit includes the active light source and the frame structure for mounting a light source). For example, the frame structure for mounting a light source may include a plurality of spacing members arranged at intervals in the vertical or horizontal direction and a surrounding member for fixing both ends of the plurality of spacing members, and a plurality of active light sources may be installed relative to the spacing members at intervals along the length of the spacing members. In addition, it is preferable that the interval between the spacing members, the thickness of the spacing members, etc. be appropriately set in consideration of the air flow in the front-rear direction, the structural rigidity of the frame structure for mounting a light source, etc.

[0039] For example, when the active light source is located at the rear, the light source mounting structure may be disposed between the second casing partition 20 and the second cover 40, and conversely, when the active light source is located at the front, the light source mounting structure may be disposed between the first casing partition 10 and the first cover 30. Such an arrangement inside the covers can provide a module type assembled in a single form. 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 may be disposed in front of the first cover 30.

[0040] 10, the active light source may be disposed behind the second casing partition 20. When the filter module is embodied in the form of an air purifier disposed inside a housing, the air flowing in from the front of the first casing partition 10, passing through the second casing partition 20 and moving backward may not be able to form a constant air flow direction due to the pressure difference until it is discharged through an air outlet provided on the upper or rear (back) side of the housing, and may form a vortex. That is, in the rear space of the second casing partition 10 after the air passes through, a vortex is formed due to the pressure difference, and in the case of the photocatalyst ball 50 accommodated in the second casing partition 10, the contact surface with the air becomes wider or the contact time becomes longer due to the vortex, so that the beneficial effect of the photocatalytic activity can be more effectively expressed. Therefore, the active light source may be disposed behind the second casing partition 20 in consideration of this point. However, the location of the active light source is not necessarily limited thereto, and may be set to a location that allows excellent air purification capability and energy consumption reduction.

[0041] In addition, the light irradiated from the active light source of the present filter module to the photocatalyst balls 50 may be light having a characteristic capable of activating the photocatalyst. The characteristics of such light are preferably set in consideration of the characteristics of the photocatalyst material contained in the photocatalyst balls 50, and as an example, the light may be light including a wavelength in the ultraviolet region. For example, the light of the active light source may be light having a wavelength in the 200nm to 390nm band, which is the wavelength of ultraviolet light, but is not limited thereto, and is preferably set to light including a wavelength with the highest photocatalytic activity efficiency. As an example, the photocatalyst material contained in the photocatalyst balls 50 may include titanium dioxide, and the light irradiated from the active light source may be set as ultraviolet light in the 360nm to 380nm wavelength band, which maximizes the photocatalytic activity efficiency of titanium dioxide and does not generate ozone. However, the photocatalyst in the present application is not necessarily limited to titanium dioxide, and it is of course possible to apply known photocatalysts and various photocatalysts to be developed in the future to the present application. In addition, the reaction between light and a photocatalyst is obvious to those skilled in the art, so a detailed explanation will be omitted.

[0042] In addition, the filter module may include a guide frame for ensuring the distance between the active light source and the photocatalyst ball 50 and an air flow path, a light reflector for minimizing the outflow of light irradiated from the active light source and maximizing the efficiency of photocatalyst activity, an active light source driver, and a power supply line.

[0043] For example, if the active light source of the filter module is a UV LED with a light irradiation angle of 120 degrees, it can irradiate light up to a range of 40 mm when a distance of 10 mm is provided. However, it is preferable to set the distance between the active light source and the photocatalyst balls 50, the number of active light sources, the interval between the active light sources, etc., taking into consideration the light irradiation angle and light amount deviation of the active light source, as well as the aspect of increasing the photocatalytic activity of the photocatalyst balls 50 and the aspect of ensuring energy efficiency.

[0044] Also, the light reflector may be disposed opposite or adjacent to the active light source unit so as to reflect light passing through the first and second casing partitions 10 and 20 or light scattered from the casing partitions 10 and 20 toward the active light source unit toward the first and second casing partitions 10 and 20. For example, in order to reflect light passing through the first and second casing partitions 10 and 20 toward the partitions 10 and 20, if the active light source unit is located at the rear, the light reflector may be disposed in front of the first casing partitions 10, and conversely, if the active light source unit is located at the front, the light reflector may be disposed behind the second casing partitions 20. Also, in order to reflect light scattered from the first and second casing partitions 10 and 20 toward the active light source unit toward the casing partitions, the light reflector may be disposed in front of the active light source unit when the active light source unit is located at the front, and conversely, if the active light source unit is located at the rear, the light reflector may be disposed behind the active light source unit.

[0045] The active light source may be arranged at least one (one or more) at the rear of the second casing partition 20 and at one front side of the first casing partition 10 or at both the front and rear sides (i.e., at least one side) as described above so as to irradiate light toward the photocatalyst balls 50 arranged in the lattice-type spaces 12, 22.

[0046] Also, the light reflector may be provided with a surface material capable of reflecting light. Also, the light reflector may preferably have a structure with a portion opened in the front-rear direction so that the flow of air in the front-rear direction is not restricted. As an example, the light reflector may be provided with a pattern corresponding to each of the lattice-shaped spaces of the first and second casing partitions 10 and 20. As a more specific example, the light reflector may include a reflective pattern portion that reflects the arriving light and an opening pattern portion that allows the arriving air to pass through. At this time, it is preferable that the reflective pattern portion is provided with a material, size, and shape that can have a reflection angle, reflectance, etc. that can efficiently reflect the arriving light toward the first and second casing partitions 10 and 20.

[0047] For example, in order to reflect light passing through the first and second casing partitions 10 and 20 back toward the casing partitions 10 and 20, when the active light source is located in the front, the light reflector may be disposed between the second casing partition 20 and the second cover 40 or behind the second cover 40, and conversely, when the active light source is located in the rear, the light reflector may be disposed between the first casing partition 10 and the first cover 30 or in front of the first cover 30. As another example, in order to reflect light scattered toward the active light source from the first and second casing partitions 10 and 20 back toward the casing partitions 10 and 20, when the active light source is located in the front, the light reflector may be disposed in front of the active light source, and conversely, when the active light source is located in the rear, the light reflector may be disposed behind the active light source. When the light reflector is disposed inside the cover, the light reflector, the cover, and the casing partition wall may be provided in a single assembled module form, and when the light reflector is disposed in front of or behind the active light source unit, the light reflector and the active light source unit (including the active light source and the frame structure for mounting the light source) may be provided in a single assembled module form.

[0048] The active light source driver and the power supply line are obvious to those skilled in the art, so a more detailed description will be omitted.

[0049] Meanwhile, referring to Figs. 1 to 5, the photocatalyst balls 50 can be accommodated in the lattice-type spaces 12 and 22 (spaces inside the partitions formed by the partitions located on the top, bottom, left and right) of the first casing partition part 10 and the second casing partition part 20 of the present filter module. Also, the photocatalyst balls 50 can be balls made of a material containing a photocatalyst substance, or balls made of other materials (e.g., ceramics or metal) in a ball shape coated with a photocatalyst. In the case of balls coated with a photocatalyst, they can be provided by applying various coating methods that are conventionally known or will be developed in the future.

[0050] Also, the diameter of the photocatalyst balls 50 can be adjusted. For example, in order to improve air purification performance by increasing the air circulation efficiency, the size (diameter) of the photocatalyst balls 50 is set smaller than the size (width or height) of the inside of the lattice-type spaces 12 and 22 of the partition wall, which will be described later, so that the air flow can be induced to be smoother. That is, the photocatalyst balls 50 are provided smaller than the size of the lattice-type spaces 12 of the first casing partition wall part 10 or the lattice-type spaces 22 of the second casing partition wall part 20 so that they can flow in the lattice-type spaces 12 and 22 in which they are accommodated in response to the air flow, so that the air flow can be smoother due to the flow of the photocatalyst balls 50. On the other hand, in order to improve the one-pass performance and improve the air purification performance, the size (diameter) of the photocatalyst balls 50 is set to the same size as the inside of the lattice-type spaces 12 and 22 of the partition wall, which will be described later, and the photocatalyst balls 50 are provided finely, so that the flowing air can be induced to contact the surface of the photocatalyst balls 50 as much as possible.

[0051] In addition, the photocatalyst ball 50 can be accommodated in one lattice space 12, 22, at least one (one or more), and can be arranged in a size that allows a clearance gap to be formed in at least one of the horizontal and vertical directions of the lattice space 12, 22, while being accommodated in one lattice space 12, 22 so that it can move within the lattice space 12, 22 in response to the air flow.

[0052] For example, when the photocatalyst balls 50 and the lattice spaces 12, 22 correspond one-to-one and one photocatalyst ball 50 is accommodated in one lattice space 12, 22 (when one photocatalyst ball 50 is accommodated in one lattice space 12, 22), the photocatalyst ball 50 is accommodated in one lattice space 12, 22, and the photocatalyst ball 50 can be provided smaller than the size of the lattice space 12 of the first casing partition part 10 or the lattice space 22 of the second casing partition part 20 so that the photocatalyst ball 50 can flow in the lattice space 12, 22 in which it is accommodated in response to the air flow. In such a case, the first cover 30 and the second cover 40 can be provided to allow air to pass through but prevent the photocatalyst ball 50 from coming off.

[0053] In addition, when the photocatalyst balls 50 and the lattice spaces 12, 22 correspond to each other in a many-to-one relationship and a plurality (N) of photocatalyst balls 50 are accommodated in one lattice space 12, 22, the photocatalyst balls 50 are accommodated in a single lattice space 12, 22, but the photocatalyst balls 50 can be accommodated in a size that allows a marginal gap to be formed in at least one of the horizontal and vertical directions of the lattice space 12, 22 when the photocatalyst balls 50 are accommodated in the lattice space 12, 22 so that the photocatalyst balls 50 can flow in the lattice space 12, 22 in which they are accommodated in response to the air flow. In such a case, the first cover 30 and the second cover 40 can be provided to allow air to pass through and prevent the photocatalyst balls 50 from coming off.

[0054] Also, the photocatalyst balls 50 may have a uniform (constant) diameter. For example, the inner size (width or height) of the lattice-type spaces 12 and 22 may be 4.5 mm, and the diameter of the photocatalyst balls 50 may be about 4 mm, but is not necessarily limited thereto, and may be set in consideration of the magnitude of the pressure difference, air purification capacity, energy consumption efficiency, etc.

[0055] As described above, the present application can adjust the air circulation efficiency or one-pass performance by adjusting the internal size (width or height) of the lattice-type spaces 12, 22 of the partitions. That is, by setting the size (width or height) of the lattice-type spaces 12 of the first casing partitions 10 or the lattice-type spaces 22 of the second casing partitions 20 to be larger than the diameter of the photocatalyst balls 50 (for example, the internal size (width or height) of the lattice-type spaces 12, 22 is 14 mm, and the diameter of the photocatalyst balls 50 is about 10 mm), the air flow becomes smoother in the air flow, and the photocatalyst balls 50 can be guided to be in maximum contact with air containing an infectious agent (virus or bacteria) (air circulation efficiency). In contrast, by setting the size (width or height) of the lattice space 12 of the first casing partition section 10 or the lattice space 22 of the second casing partition section 20 to be the same as the size (diameter) of the photocatalyst ball 50 (for example, the internal size (width or height) of the lattice spaces 12, 22 is 4.5 mm, and the diameter of the photocatalyst ball 50 is approximately 4 mm), the photocatalyst ball 50 can be guided to make maximum contact with the source of infection (virus or bacteria) in the air flowing along the air (a method of improving air purification performance by improving One pass performance).

[0056] The distance between the photocatalyst ball 50 and a partition wall (described later) can be set in consideration of the magnitude of the pressure difference due to the air flow, the air purification capacity, and the energy consumption efficiency.

[0057] Meanwhile, the first casing partition part 10 is configured to have a plurality of spaces (lattice-type spaces) 12 in a lattice arrangement in which the above-mentioned photocatalyst balls 50 can be positioned. For example, the first casing partition part 10 may be provided in the form of an insect screen (mesh or lattice). It is preferable that the first casing partition part 10 is provided to have a thickness in the front-rear direction sufficient to accommodate the photocatalyst balls 50. Referring to FIG. 5, the first casing partition part 10 may be disposed relatively forward of the second casing partition part 20.

[0058] Also, referring to FIG. 1 and FIG. 3, the first casing partition 10 may be disposed on the back side of the first cover 30. For example, the first casing partition 10 may be coupled (connected) to the first cover 30 through a fastening means such as a screw connection. However, the fastening method between the first casing partition 10 and the first cover 30 disposed in front of it is not limited to only the screw connection, and various known fastening methods may be applied. For example, the first casing partition 10 may be provided with a shape having a rectangular outline when viewed from the front. Also, the lattice-type space 12 formed in the first casing partition 10 to accommodate the photocatalyst balls 50 may be provided with a space having a rectangular outline when viewed from the front. However, the shape and size of the first casing partition 10 and the lattice-type space 12 formed therein are not limited thereto.

[0059] Also, for example, the material of the first casing partition 10 may be a material including, but not limited to, metal, acrylic, ceramics, plastic (PVC, PC, PE, ABS, etc.), EGI steel plate, etc. The material of the first casing partition 10 may be determined in consideration of noise, vibration, flow of the photocatalytic balls 50 in the lattice space 12, etc.

[0060] Also, the first casing partition 10 may be coated or molded with a photocatalyst. That is, the first casing partition 10 itself may be provided to perform a target function through photocatalytic activity, independent (separate) from the photocatalyst balls 50. Such coating or molding of the photocatalyst material may be realized by various photocatalyst coating or molding methods that can be understood by a person of ordinary skill in the art.

[0061] For example, the manufacturing method of the first casing partition 10 may include, but is not limited to, an injection mold, a press mold, a laser cutting, a water jet, and the like.

[0062] For reference, Fig. 13 is a diagram for explaining an example of a method for manufacturing the first casing partition part 10 or the second casing partition part 20 of the present filter module. Referring to Fig. 13, the partitions of the first casing partition part 10 may be formed by separately manufacturing a horizontal partition and a vertical partition, and an incision made in the front-rear direction may be formed in each of the horizontal partition and the vertical partition, and the horizontal partition and the vertical partition may be coupled to each other by fitting the incisions. For example, one of the horizontal partition and the vertical partition may have an incision recessed from front to rear, and the other may have an incision recessed from rear to front, so that the horizontal partition and the vertical partition may be coupled to each other with the incisions facing each other.

[0063] According to this, each of the first casing partition part 10 and the second casing partition part 20 may include a horizontal partition wall and a vertical partition wall. Also, referring to Fig. 13, one of the horizontal partition wall and the vertical partition wall may have a first cutout part recessed from front to rear, and the other of the horizontal partition wall and the vertical partition wall may have a second cutout part recessed from rear to front and engaging with the first cutout part, and the horizontal partition wall and the vertical partition wall may be connected to each other by engaging the first cutout part and the second cutout part. Specifically, the first cutout part and the second cutout part may be connected to each other by engaging a rear part of the first cutout part (a part of the first cutout part that is most deeply recessed) and a front part of the second cutout part (a part of the second cutout part that is most deeply recessed).

[0064] The thickness of the partition wall may be about 0.1 mm to 1.2 mm, and more preferably 0.5 mm to 1.0 mm. If the partition wall is too thick, the pressure difference increases and the air flow rate decreases, which is undesirable, and if the partition wall is too thin, it may be difficult to obtain the rigidity required to maintain the shape. However, the thickness is not limited to this and can be determined in consideration of the material, air purification capacity, cost, etc.

[0065] Meanwhile, the first cover 30 covers the front surface of the first casing partition part 10 and is configured to prevent the photocatalytic balls 50 accommodated in the lattice-type space 12 of the first casing partition part 10 from escaping, and may be disposed in front of the first casing partition part 10. Referring to FIG. 3, the first cover 30 may include a ball detachment prevention member 31 extending across the middle (e.g., center) of the lattice-type space 12 of the first casing partition part 10. As an example, the ball detachment prevention member 31 may be a plurality of members extending in the vertical direction and spaced apart in the horizontal direction, but is not limited thereto. As another example, the ball detachment prevention member 31 may be a member extending in the horizontal direction, or a mesh-shaped member extending both horizontally and vertically. In addition, the arrangement intervals of the ball detachment prevention members 31 may be set to an interval that can prevent the detachment of the photocatalytic balls 50 in consideration of the size (diameter) of the photocatalytic balls 50. For example, when the size of the photocatalyst balls 50 is very small compared to the internal size of the lattice space 12, a plurality of ball escape prevention members 31 may be arranged to cross one lattice space 12. Also, a plurality of photocatalyst balls 50 having a small diameter may be placed in one lattice space 12 and covered and fixed with a mesh-shaped lid.

[0066] As described above, the first casing partition 10 may be connected to the second casing partition 20 through a fastening means such as a screw connection. For example, the fastening means may include a long screw capable of connecting the first cover 30, the first casing partition 10, the second casing partition 20, and the second cover 40 all at once. However, the fastening means is not limited thereto, and various types of fastening means that are conventionally known or will be developed in the future may be applied to the fastening means. Of course, the fastening means described below may also be applied.

[0067] Meanwhile, the second casing partition part 20 is coupled to the rear of the first casing partition part 10, and is configured to have a plurality of lattice-type spaces 22 that are alternately positioned with the lattice-type spaces 12 of the first casing partition part 10. The second casing partition part 20 may be prepared using the same or similar material, manufacturing method, etc. as the first casing partition part 10, and may be connected to the adjacent components (the first casing partition part 10 and the second cover 40) by the same or similar fastening means. Therefore, the following description will focus on the differences from the first casing partition part 10, and detailed description of the contents already described for the first casing partition part 10 and contents that can be understood by referring to the drawings will be omitted.

[0068] FIG. 6 is a schematic front view illustrating the alternating arrangement of the first casing partition section 10 and the second casing partition section 20 of the present filter module, and FIG. 7 is a conceptual diagram illustrating the alternating arrangement of the first casing partition section 10 and the second casing partition section 20 of the present filter module.

[0069] 5 to 7, the second casing partition wall 20 can be stacked in the front-rear direction behind the first casing partition wall 10 in an alternating manner. Such alternating stacking is for increasing the contact area of ​​the air passing through the filter module and the photocatalyst balls 50, taking into consideration the air flow over the surfaces of the photocatalyst balls 50 housed in the first casing partition wall 10 and the photocatalyst balls 50 housed in the second casing partition wall 20. Therefore, when stacking in the alternating stacking method, it is preferable to set the degree of alternating stacking in consideration of the degree of rear pressure differential generated by the air flow passing through the filter module, the air purification capacity by the photocatalytic activity reaction, energy consumption efficiency, etc.

[0070] More specifically, referring to Figures 5 to 7 (mainly Figure 6) together, the alternating arrangement of the first casing partition section 10 and the second casing partition section 20 means that, when viewed from the front (front) or rear (rear), the partition of the first casing partition section 10 crosses the center of the lattice-type space 22 of the second casing partition section 20, and conversely, the partition of the second casing partition section 20 crosses the center of the lattice-type space 12 of the first casing partition section 10, so that the two partitions are arranged not to coincide with each other but to be offset (separated laterally). This can be clearly understood from the details shown in Figures 5 to 7.

[0071] Fig. 8 is a conceptual diagram for explaining the extent to which a gap (space) is formed between the photocatalyst balls 50 accommodated in the first casing partition part 10 and the photocatalyst balls 50 accommodated in the second casing partition part 20 or the extent to which both photocatalyst balls 50 overlap each other when viewed from the front depending on the settings of the size of the photocatalyst balls 50, the size of the lattice space, the partition thickness, etc. when the first casing partition part 10 and the second casing partition part 20 of this filter module are alternately arranged. Also, Fig. 9 is a drawing showing a design example for considering the arrangement area depending on the arrangement of the photocatalyst balls 50. Referring to FIG. 8 as an example, in order to purify air in a manner that enhances One Pass performance, photocatalytic balls 50 with a diameter of 4 mm are enclosed in lattice spaces 12, 22 spaced 4.5 mm apart, and when the lattice spaces 12, 22 are alternately arranged as described above, the maximum separation distance s between the photocatalytic balls 50 in the first casing partition 10 and the photocatalytic balls 50 in the adjacent second casing partition 20 when viewed from the front can be 0.2426 mm (referring to FIG. 8, the separation distance is considered to be the separation distance when the photocatalytic balls 50 are closely attached to the top of the left side or the bottom of the right side in the lattice spaces 12, 22). In this way, when the partition walls are spaced 4.5 mm apart to confine photocatalyst balls 50 with a diameter of 4 mm, it can be seen that even if the photocatalyst balls 50 are arranged in two tiers, the air passing through them may pass without coming into contact with the photocatalyst balls 50 due to the formation of a space (separation distance s) between them of 0.2426 mm. Therefore, it is necessary to set the optimal separation distance between the photocatalyst balls 50 by experiment, simulation, etc., taking into account the air flow rate and the contact level with the photocatalyst balls 50 (see FIG. 9).

[0072] Therefore, the first casing partition portion 10, the second casing partition portion 20 and the photocatalyst balls 50 can be arranged so that the first photocatalyst balls 50 arranged in the lattice-type space 12 of the first casing partition portion 10 and the second photocatalyst balls 50 arranged in the lattice-type space 22 of the second casing partition portion 20, which are alternately adjacent to the lattice-type space 12 of the first casing partition portion 10 in a form that partially overlaps in the front-to-rear direction, are separated as far away from each other as possible, so that the first photocatalyst balls 50 and the second photocatalyst balls 50 can be arranged so that they partially overlap when viewed from the front or rear.

[0073] In other words, the first casing partition 10, the second casing partition 20 and the photocatalyst balls 50 can be arranged so that even if one or more of the first and second photocatalyst balls 50 and 50 do not have the same center as the center of the lattice-type space 12, 22 in which they are accommodated, the first and second photocatalyst balls 50 partially overlap each other when viewed from the front or rear, that is, the separation distance s is not formed between the first and second photocatalyst balls 50. This can reduce the possibility that air passes through the photocatalyst balls 50 without contacting them.

[0074] In addition, the plurality of lattice-type spaces 22 of the second casing partition part 20 may be alternately positioned with the plurality of lattice-type spaces 12 of the first casing partition part 10 so that no separation distance is formed in the diagonal direction between the photocatalyst balls (second photocatalyst balls) 50 accommodated therein and the photocatalyst balls (first photocatalyst balls) 50 accommodated in each of the plurality of lattice-type spaces 12 of the first casing partition part 10. In other words, the first casing partition part 10, the second casing partition part 20 and the photocatalyst balls 50 may be provided so that no separation distance s is formed in the diagonal direction between the first photocatalyst balls 50 and the second photocatalyst balls 50.

[0075] For reference, referring to Figure 8, here, being diagonally spaced may mean that when the lattice spaces 12 of the first casing partition section 10 and the lattice spaces 22 of the second casing partition section 20 are arranged alternately in the horizontal and vertical directions, the first photocatalyst balls 50 arranged in the lattice space 12 of the first casing partition section 10 and the second photocatalyst balls 50 arranged in the lattice space 22 of the second casing partition section 20 are spaced as far apart as possible.

[0076] In the case of this filter module, it is necessary to select materials and modularize parts while taking into consideration optimization of filter performance and mass production. In particular, it is necessary to manufacture it while taking into consideration the degree of differential pressure generation, air purification efficiency (one pass, air circulation, etc.), energy consumption efficiency, etc.

[0077] 4(a), 5 and 6(b), the second casing partition part 20 may have holes 21 formed in at least one of the upper, lower, left and right partitions forming the lattice-type space 22, through hole processing, etc., for mutual air communication with the adjacent lattice-type space 22. Thus, the air flowing in from the front and passing through the lattice-type spaces 12 and 22 of the filter module casing partition parts 10 and 20 may form a vortex in a closed space except for the air outlet on the back side, and thus air rotation may occur on the back side of the second casing partition part 20. Therefore, in order to make the air flow caused by the vortex on the back side smoother, the holes 21 may be formed in the partitions forming the lattice-type spaces 22 of the second casing partition part 20. The holes 21 allow the air that has moved to a specific lattice-type space 22 to move again to the adjacent lattice-type space 22 through the holes, thereby reducing the pressure difference and increasing the contact area with the photocatalyst balls 50. The hole 21 may be formed in one or more partition walls in consideration of air flow efficiency.

[0078] 2 and 4, the second cover 40 covers the rear surface of the second casing partition 20 and prevents the photocatalytic balls 50 accommodated in the lattice-type space 22 of the second casing partition 20 from slipping out. The second cover 40 can be understood to be the same as or similar to the first cover 30 with reference to the drawings, and therefore, redundant descriptions such as the ball slip-out prevention member 41, fastening means, etc. will be omitted.

[0079] Meanwhile, Fig. 11 is a drawing for explaining an embodiment (leftmost drawing) of a one-body type (1-body type) and an embodiment (remaining drawings) of a module type (module type) of the first cover 30 of the present filter module, Fig. 12 is a drawing for explaining an embodiment (leftmost drawing) of a one-body type (1-body type) and an embodiment (remaining drawings) of a module type (module type) of the first casing partition wall part 10 of the present filter module, Fig. 14 is a drawing for explaining an embodiment (leftmost drawing) of a one-body type (1-body type) and an embodiment (remaining drawings) of a module type (module type) of the second casing partition wall part 20 of the present filter module, and Fig. 15 is a drawing for explaining an embodiment (leftmost drawing) of a one-body type (1-body type) and an embodiment (remaining drawings) of a module type (module type) of the second cover 40 of the present filter module.

[0080] 11, 12, 14 and 15, the first cover 30, the first casing partition 10, the second casing partition 20, the second cover 40, etc. of the present filter module may be manufactured as an integrated unit, or as an assembly type in which the sub-components (parts) constituting each component are separated. That is, the present filter module may be provided as an integrated unit, but may also be modularized as an assembly type to ensure ease of module manufacture and maintenance, and such a module type is preferably determined in consideration of the conditions under which the present filter module is applied.

[0081] The present application also provides an air purification device including the above-described filter module.

[0082] Meanwhile, FIG. 16 is a diagram for explaining an embodiment in which the filter module is provided by coating the casing partitions 10 and 20 with a photocatalyst without arranging the photocatalyst balls 50 or by molding the casing partitions 10 and 20 themselves from a material containing a photocatalyst material.

[0083] 16, the present application may provide a form in which the first casing partition part 10 and the second casing partition part 20 are configured to have a denser interval (for example, 1 mm to 2 mm, but is not limited thereto) instead of removing the photocatalyst balls 50 from the above-described filter module, and the casing partition parts 10, 20 themselves are coated or molded with a photocatalyst. In this case, too, the first casing partition part 10 and the second casing partition part 20 are arranged alternately, so that an infectious source (virus or bacteria) in the air flowing along with the air passing through the alternatingly arranged lattice-type spaces 12, 22 comes into contact with the photocatalyst material present on the entire surface of the partition, thereby realizing antiviral or antibacterial performance against the infectious source (virus or bacteria).

[0084] 16, an embodiment of the present filter module excluding the photocatalyst balls 50 may include a first casing partition part 10 and a second casing partition part 20. In addition, the embodiment of the present filter module excluding the photocatalyst balls 50 may be provided in such a form that the partition of the second casing partition part 20 crosses the lattice-type space 12 of the first casing partition part 10, or conversely, the partition of the first casing partition part 10 crosses the lattice-type space 22 of the second casing partition part 20, when viewed from the front or rear. In addition, in the case of an embodiment of the present filter module excluding the photocatalyst balls 50, unlike the embodiment including the photocatalyst balls 50 described above, the photocatalyst balls 50 are not disposed in the lattice-type spaces 12 and 22, and therefore the first cover 30 or the second cover 40 may be omitted as necessary.

[0085] In addition, the present application can provide an air purifying device including the present filter module, which is provided by coating the casing partition with a photocatalyst without disposing photocatalyst balls, or by molding the casing partition itself from a material containing a photocatalyst substance.

[0086] The above description of the present application is for illustrative purposes only, and a person having ordinary skill in the art to which the present application pertains will understand that the present application can be easily modified into other specific forms without changing the technical idea or essential features of the present application. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and are not limiting. For example, each component described as a single type may be implemented in a distributed form, and similarly, each component described as a distributed type may be implemented in a combined form.

[0087] The scope of the present application is defined by the claims set forth below rather than the above detailed description, and all modifications and variations derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present application.
