Description

Technical Field

[0001] The present invention relates to a sterilization module. Background Art

[0002] Air conditioners are devices that adjust the indoor air temperature to the temperature set by the user. They cool or heat the indoor air based on the principle of the refrigeration cycle. Air conditioners can be classified into wall-mounted, vertical, and ducted types based on the installation method of the indoor unit.

[0003] The air conditioner may be provided with a filter for filtering foreign matter such as dust and powder floating in the air taken in. As the air conditioner is repeatedly used, foreign matter accumulates in the filter, thereby causing problems such as a decrease in the air purification ability of the filter, a bad odor, and a decrease in air flow.

[0004] Therefore, a sterilizing device for sterilizing the filter can be provided in the air conditioner. Summary of the invention

[0005] Problem that the invention aims to solve

[0006] An object of the present invention is to provide a sterilization module capable of uniformly sterilizing the surface of a filter that is easily contaminated, and an air conditioner including the same.

[0007] Another object of the present invention is to provide a sterilization module capable of emitting light having uniform illuminance and an air conditioner including the same.

[0008] Another object of the present invention is to provide a sterilization module capable of adjusting a radiation angle along a longitudinal direction of the sterilization module and an air conditioner including the same.

[0009] Another object of the present invention is to provide a sterilization module capable of adjusting a radiation angle along a circumferential direction of the sterilization module and an air conditioner including the same.

[0010] Another object of the present invention is to provide a sterilization module capable of minimizing light loss and an air conditioner including the same.

[0011] Another object of the present invention is to provide a sterilization module capable of irradiating light to the inside of a bent portion of a bent filter, and an air conditioner including the same.

[0012] Another object of the present invention is to provide a sterilization module and an air conditioner including the same, which can sterilize the entire surface with one light source when sterilizing a long or wide surface.

[0013] The subject of the present invention is not limited to the above-mentioned subject, and other subjects not mentioned can be clearly understood by those skilled in the art from the following description.

[0014] Technical solutions to the problem

[0015] In order to achieve the above-mentioned problem, the sterilization module of the embodiment of the present invention may include: a light source module for generating light; a light guide extending in a first direction, the light being incident on the light guide; a main body, the top surface of which is open, supporting the light guide disposed inside. The light guide includes a first side surface and a second side surface, the second side surface being disposed on the opposite side of the first side surface in the first direction; the light source module is disposed on the first side surface of the light guide, so that the light is incident on the light guide. Thus, by using one light source, it is possible to reduce the material cost of the sterilization module and simplify the wiring structure.

[0016] The cross section of the light guide may be formed into a circular shape, thereby realizing a sterilization module that emits a linear light source.

[0017] The light source module may include a light source that generates light having a wavelength of 100 nm to 280 nm. The light guide may be formed of a material having a high transmittance to the light. Thus, the sterilization power can be improved.

[0018] The light guide may include: a first curved section connecting the first side surface and the second side surface to form a curved surface; and a second curved section connecting the first side surface and the second side surface to form a curved surface and arranged below the first curved section. A reflection pattern may be formed in the second curved section. The light incident on the light guide may be reflected in the second curved section and emitted toward the first curved section. Thus, total reflection can be achieved in the length direction of the light guide.

[0019] The reflective pattern may include a plurality of first reflective patterns, the plurality of first reflective patterns extending along the first direction and spaced apart from each other along the first direction. The spacing distance of the plurality of first reflective patterns may decrease as they move away from the light source module. Thus, light irradiation with uniform illumination can be achieved by adjusting the reflective pattern.

[0020] The reflective pattern may include a plurality of second reflective patterns, the plurality of second reflective patterns extending along a second direction perpendicular to the first direction and spaced apart from each other along the first direction. The spacing distance of the plurality of second reflective patterns may decrease as they move away from the light source module. Thus, light irradiation with uniform illumination can be achieved by adjusting the reflective pattern.

[0021] The main body may include a gripping member, the gripping member being coupled to a bottom plate of the main body and gripping the light guide, thereby enabling the light guide to be fixed to the main body.

[0022] The main body may include a bottom plate, a first side plate, and a second side plate, wherein the first side plate extends upward from the bottom plate and has a length direction along the first direction, and the second side plate extends upward from the bottom plate and is arranged on the opposite side of the first side plate. A reflector may be arranged on the bottom plate, the first side plate, and the second side plate. Thus, light loss in the direction of the reflection pattern of the light guide can be reduced by arranging the reflector on the main body.

[0023] The reflector may contain aluminum. Since the reflector is made of a material having a high reflectivity with respect to the UV-C wavelength, light loss in the direction of the reflection pattern of the light guide can be reduced.

[0024] The reflector may include a first reflector disposed on the first side plate and a second reflector disposed on the second side plate. The distance between the first reflector and the second reflector along the second direction may increase as it approaches upward along the third direction, wherein the second direction is a direction perpendicular to the first direction, and the third direction is a direction perpendicular to both the first direction and the second direction. Thus, the radiation angle adjustment can be achieved by adjusting the reflector that is not disposed on the light guide but on the main body.

[0025] At least a portion of the reflector may be formed as a curved surface. Thus, the radiation angle can be adjusted by adjusting the reflector that is not arranged on the light guide but on the main body.

[0026] The light guide may include one end and another end, the one end including the first side surface, and the other end including the second side surface. The sterilization module may include a fixing member for fixing the other end of the light guide. The fixing member may be formed with a groove for inserting the other end of the light guide. Thus, the cylindrical light guide can be prevented from rotating.

[0027] The main body may include a bottom plate, a first side plate, a second side plate, a third side plate and a fourth side plate, wherein the first side plate extends upward from the bottom plate, the second side plate is arranged on the opposite side of the first side plate, the third side plate connects the first side plate and the second side plate and faces the first side surface of the light guide, and the fourth side plate is arranged on the opposite side of the third side plate. The other end of the light guide may include a first recessed portion, the first recessed portion is recessed inwardly from at least a portion of the outer circumference of the other end of the light guide, and faces the first side plate of the main body. The other end of the light guide may include a second recessed portion, the second recessed portion is recessed inwardly from at least a portion of the outer circumference of the other end of the light guide, and faces the second side plate of the main body. The first recessed portion and the second recessed portion may be formed as planes. Thus, the cylindrical light guide can be prevented from rotating.

[0028] The other end of the light guide may include a recessed portion, the recessed portion being recessed from at least a portion of the outer circumferential surface of the other end of the light guide, and the recessed portion facing the bottom plate of the main body. The recessed portion may be formed as a plane. Thus, the cylindrical light guide can be prevented from rotating.

[0029] The light source module may include a substrate and a light source mounted on the substrate. The main body may include a first side panel facing the first side surface of the light guide; the first side panel of the main body may include a first surface, a second surface and a hole, the first surface faces the first side surface of the light guide, the second surface is arranged on the opposite side of the first surface, and the hole passes through the first surface and the second surface. The substrate may be arranged on the second surface of the first side panel of the main body, and the light source may be arranged in the hole of the first side panel. Thus, the space where the light source module and the light guide are set can be separated, the substrate can be protected by the separation space, and the short circuit phenomenon between the light source installed on the substrate through the hole and the substrate can be minimized.

[0030] The light source module may include a connector. The substrate may include a first portion and a second portion, the first portion being configured on the first side plate of the main body, and the second portion being bent from the first portion and configured with the connector. The sterilization module may include a cover, the cover being combined with the main body and covering the first portion and the second portion of the substrate. Thus, the substrate, the light source as a substrate mounting component, and the connector can be protected.

[0031] Details of other embodiments are included in the detailed description and accompanying drawings.

[0032] Effects of the Invention

[0033] The sterilization module of the present invention has one or more of the following effects.

[0034] First, the surface of the filter, which is susceptible to contamination, can be sterilized uniformly.

[0035] Second, it is possible to emit light having uniform illuminance.

[0036] Third, the radiation angle along the length direction of the sterilization module can be adjusted.

[0037] Fourth, the radiation angle along the circumferential direction of the sterilization module can be adjusted.

[0038] Fifth, it can minimize light loss.

[0039] Sixth, light can be irradiated to the inner side of the bent portion of the bent filter.

The second curve section 240 may change the light path of the light incident into the interior of the light guide 200 along the first direction. Thus, a point light source with strong linearity may be emitted through the first curve section 230. The second curve section 240 may be referred to as a light reflecting surface.

[0085] Reference Figure 6 , Figure 7 and Fig.10 , a reflection pattern 250 may be formed in the second curve interval 240. The reflection pattern 250 may include a plurality of reflection patterns 250. The plurality of reflection patterns 250 may be arranged along the first direction 12 of the light guide 200. The plurality of reflection patterns 250 may be spaced apart along the first direction 12. The spacing distance d between the plurality of reflection patterns 250 along the first direction 12 may be smaller as the first side surface 211 of the light incident on the light guide 200 is closer to the second side surface 221. The density of the plurality of reflection patterns 250 increases as they are farther away from the light source 320. Thus, a uniform illumination can be formed in the entire length direction of the light guide 200.

[0086] The reflective pattern 250 may be formed in the entire region of the second curved section 240. Alternatively, the reflective pattern 250 may be formed in a partial region of the second curved section 240.

[0087] The reflective pattern 250 may be formed in the second curved section 240 in a positive angle or negative angle form. If the reflective pattern 250 is a negative angle, the reflective pattern 250 may be formed in a groove form. If the reflective pattern 250 is a positive angle form, the reflective pattern 250 may be formed in a protrusion form. Figure 8 and Fig. 9In the case where the reflective pattern 250 is in a positive angle form, the reflective pattern 250 may include a light reflecting member 253. The light reflecting member 253 may protrude upward from the inner circumference of the second curved section 240. The light reflecting member 253 may be formed in various shapes. For example, the cross section of the light reflecting member 253 may be formed in at least any one of a triangular shape, a cone shape, and a hemispherical shape. The following is an example of a case where the cross section of the light reflecting member 253 is a triangular shape.

[0088] The light reflecting member 253 may include a plurality of light reflecting members 253. The plurality of light reflecting members 253 may be combined to form a reflection pattern 250. The plurality of light reflecting members 253 may be spaced apart in the second curve section 240 along the circumferential direction of the light guide 200 or the longitudinal direction of the light guide 200 to form the reflection pattern 250.

[0089] Reference Figure 8 , a plurality of light reflecting members 253 may be arranged in a spaced relationship along the circumferential direction of the light guide 200 in the second curved section 240 to form a first reflecting pattern 251. Fig.11 , the first reflection pattern 251 may include a plurality of first reflection patterns 251. The plurality of first reflection patterns 251 may be spaced apart along the length direction of the light guide 200. The spacing distance d between the plurality of first reflection patterns 251 along the first direction may be larger as the first side surface 211 of the light guide 200, where light is incident, is closer to the second side surface 221 of the light guide 200. Fig.11 , the light guide 200 may include a first portion 200a, a second portion 200b, and a third portion 200c sequentially arranged along the first direction 12 from the first side surface 211 of the light guide 200. The first portion 200a of the light guide 200 may be a portion where the spacing distance d between the plurality of first reflection patterns 251 is formed as the first spacing distance d1. The second portion 200b of the light guide 200 may be a portion where the spacing distance d between the plurality of first reflection patterns 251 is formed as the second spacing distance d2. The third portion 200c of the light guide 200 may be a portion where the spacing distance d between the plurality of first reflection patterns 251 is formed as the third spacing distance d3. At this time, the first spacing distance d1 may be greater than the second spacing distance d2, and the second spacing distance d2 may be greater than the third spacing distance d3. By configuring the first reflection patterns 251 so that the density between the first reflection patterns 251 increases as they are farther away from the light source 320, the illumination of the light emitted from the light guide 200 can be made uniform. The illuminance of light along the longitudinal direction of the light guide 200 can be made uniform.

[0090] Reference Fig. 9 The plurality of light reflecting members 253 are arranged in a spaced relationship along the length direction of the light guide 200 in the second curve section 240 to form a second reflecting pattern 252. Fig.12 , the second reflection pattern 252 may include a plurality of second reflection patterns 252. The plurality of second reflection patterns 252 may be spaced apart along the length direction of the light guide 200. The spacing distance d between the plurality of second reflection patterns 252 along the first direction may be larger as the first side surface 211 of the light guide 200, where light is incident, is closer to the second side surface 221 of the light guide 200. Fig.12 , the light guide 200 may include a first portion 200a, a second portion 200b, and a third portion 200c sequentially arranged along the first direction 12 from the first side surface 211 of the light guide 200. The first portion 200a of the light guide 200 may be a portion where the spacing distance d between the plurality of second reflection patterns 252 is formed as the first spacing distance d1. The second portion 200b of the light guide 200 may be a portion where the spacing distance d between the plurality of second reflection patterns 252 is formed as the second spacing distance d2. The third portion 200c of the light guide 200 may be a portion where the spacing distance d between the plurality of second reflection patterns 252 is formed as the third spacing distance d3. At this time, the first spacing distance d1 may be greater than the second spacing distance d2, and the second spacing distance d2 may be greater than the third spacing distance d3. That is, by configuring the second reflection patterns 252 so that the density between the second reflection patterns 252 increases as they are farther away from the light source 320, the illumination of the light emitted from the light guide 200 can be made uniform.

[0091] In addition, refer to Fig.12 , the plurality of second reflective patterns 252 may be spaced apart along the circumferential direction of the light guide body 200 .

[0092] Reference Fig.13 , the first reflective pattern 251 and the second reflective pattern 252 may be combined to form a third reflective pattern.

[0093] Reference Figures 11 to 13 , the length of the first portion 200a of the light guide 200 along the first direction 12, the length of the second portion 200b of the light guide 200 along the first direction 12, and the length of the third portion 200c of the light guide 200 along the first direction 12 may be determined according to the required illumination. For example, the length of the first portion 200a of the light guide 200 along the first direction 12 may be less than the length of the second portion 200b of the light guide 200 along the first direction 12. The length of the first portion 200a of the light guide 200 along the first direction 12 may correspond to the length of the third portion 200c of the light guide 200 along the first direction 12.

[0094] Reference Fig.10The reflection pattern 250 can reflect the light incident on the light guide 200. The light reflected by the reflection pattern 250 can be emitted toward the first curve section 230 of the light guide 200 and outside the light guide 200 through the first curve section 230. The light emitted from the light guide 200 can be irradiated to the sterilization target substance.

[0095] Hereinafter, the light loss reduction structure of the light guide body 200 will be described with reference to the drawings.

[0096] Reference Figure 6 and Figure 7 , a reflective plate 180 may be disposed on the main body 100. The reflective plate 180 may be disposed on the inner side of the main body 100.

[0097] The reflective plate 180 may surround at least a portion of the light guide 200. The reflective plate 180 may be configured to surround the second curve section 240 of the light guide 200. Thus, the reflective plate 180 can reduce light loss along the direction of the reflection pattern 250. The reflective plate 180 may reflect light that is transmitted along a portion of the second curve section 240 where the reflection pattern 250 is not formed. The light reflected by the reflective plate 180 may be emitted through the first curve section 230 of the light guide 200. The light reflected by the reflective plate 180 may be irradiated to the sterilization object through the top surface of the opening of the main body 100.

The reflective plate 180 may be formed of a material having high reflectivity for wavelengths of 100 to 280 nm. The reflective plate 180 may be formed of aluminum.

[0099] In the sterilization module 10 of the embodiment of the present invention, the reflective plate 180 is not formed on the light guide 200, but is formed on the main body 100 that fixes the light guide 200, so that the shape of the reflective plate 180 can be freely adjusted. The radiation angle of the light guide 200 can be adjusted by adjusting the shape of the reflective plate 180. The relevant content will be described later.

The first reflective plate 181 may be formed to be inclined downwardly from the top surface of the main body 100 toward the bottom plate 120 of the main body 100. The distance in the horizontal direction between the first reflective plate 181 and the outer side surface of the first side plate 130 may increase as it moves from the top surface of the main body 100 toward the bottom plate 120 of the main body 100.

[0151] The sterilization module 10 of the embodiment of the present invention can be applied to an air conditioner. The sterilization module 10 of the embodiment of the present invention can be applied to a duct-type air conditioner. The sterilization module 10 can be applied to sterilize filters of an air conditioner or a duct-type air conditioner. However, it is not limited thereto. The sterilization module 10 of the embodiment of the present invention can be applied to sterilize components that need to be sterilized, such as filters and fans. The following description is based on the example that the sterilization module 10 is applied to a duct-type air conditioner 1.

[0152] Hereinafter, an air conditioner 1 according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0153] Fig.18 It is a diagram showing an air conditioner according to an embodiment of the present invention. Fig.19 The present invention is an embodiment of an air conditioner equipped with Figure 1 A diagram of an example of a sterilization module. Fig. 20 and Fig.21 It is shown Fig.19 Diagram of the radiation angle of the sterilization module. Fig. 22 The present invention is an embodiment of an air conditioner equipped with Figure 1 FIG. 1 is a diagram of another example of a sterilization module. Fig.23 It is shown Fig. 22 Diagram of the radiation angle of the sterilization module.

[0154] Reference Fig.18The air conditioner 1 may be a duct type air conditioner 1 in which the suction port 601 is connected to the suction pipe 2 and the discharge port 602 is connected to the discharge pipe 3. The indoor unit of the duct type air conditioner 1 may be arranged in the space between the ceiling or the inside of the wall. The duct type air conditioner 1 may be located in the inner space of the wall without occupying the inner space of the room.

[0155] The duct type air conditioner 1 may include a housing 600, and the housing 600 includes: an inlet 601 for air to flow in; and an outlet 602 formed on the opposite side of the inlet 601 and for air to be discharged. An air supply fan (not shown) for causing air to flow from the inlet 601 of the housing 600 toward the outlet 602 may be arranged inside the housing 600. A motor (not shown) for rotating the air supply fan (not shown) may be arranged on one side of the air supply fan (not shown). A heat exchanger (not shown) for heat exchange between the air flowing toward the outlet 602 by the air supply fan (not shown) and the refrigerant may be arranged inside the housing 600. A filter F may be arranged between the air supply fan (not shown) and the inlet 601. The filter F may be arranged at the inlet 601. The duct type air conditioner 1 may further include a pre-filter (not shown), which is arranged at the front end of the filter F to filter larger foreign matter once. The filter F, the air supply fan (not shown), and the heat exchanger (not shown) may be arranged in this order along a direction from the suction port 601 toward the discharge port 602 of the housing 600 .

[0156] The housing 600 may include: a top plate 610; a bottom plate 620, which is separated from the top plate 610 along the third direction 16; and a side plate 630, which connects the top plate 610 and the bottom plate 620. The interior of the housing 600 is hollow, and the housing 600 may have a quadrilateral column shape with one side formed with an inlet 601 and the other side formed with an outlet 602 being open. The one side formed with the inlet 601 and the other side formed with the outlet 602 may be arranged in opposite directions to each other. Thus, an air flow path extending in the horizontal direction may be formed inside the housing 600.

[0157] The filter F may be a pleated filter. The filter F may be bent in a zigzag shape along a second direction 14 perpendicular to the first direction 12. However, it is not limited thereto, and the filter F may include a filter having a flat surface.

[0158] The duct type air conditioner 1 may include a sterilization module 10. The sterilization module 10 may be disposed between the suction port 601 of the housing 600 and the filter F. The sterilization module 10 may be disposed at the suction port 601 of the housing 600. The sterilization module 10 may sterilize the filter F.

[0159] The sterilization module 10 may be configured such that the top surface of the opening of the sterilization module 10 faces the filter F. The sterilization module 10 may be configured such that the second curve section 240 faces the filter F. The sterilization module 10 may be arranged perpendicular to the bending direction of the filter F. The sterilization module 10 may extend along the first direction 12 perpendicular to the second direction 14. Thus, light can be irradiated to the inner side of the bending portion.

[0160] Reference Fig.19 , the sterilization module 10 can be located in the central part of the suction port 601. The sterilization module 10 can be separated from the bottom plate 620 of the housing 600 by a first distance L1 in the up-down direction (third direction 16). The sterilization module 10 can be separated from the top plate 610 of the housing 600 by a second distance L2 in the up-down direction (third direction 16). At this time, the first distance L1 and the second distance L2 can be formed identically. The top surface of the opening of the main body 100 in the sterilization module 10 can face the filter F.

[0161] The length of the sterilization module 10 along the first direction 12 may correspond to the length of the filter F along the first direction 12. The light guide 200 of the sterilization module 10 may be formed to have a length corresponding to the length of the filter F along the first direction 12. In this case, the entire area of ​​the filter F can be sterilized using one sterilization module 10.

[0162] The length of the sterilization module 10 along the first direction 12 may be smaller than the length of the filter F along the first direction 12. The length of the light guide 200 along the first direction 12 may be smaller than the length of the filter F along the first direction 12. In this case, the radiation angle along the length direction of the sterilization module 10 can be adjusted by adjusting the shape and position of the reflector 180 disposed in the main body 100 of the sterilization module 10. Thus, the entire area of ​​the filter F having a length greater than that of the sterilization module 10 can be sterilized.

[0163] In addition, when the length of the sterilization module 10 along the first direction 12 is smaller than the length of the filter F along the first direction 12, the sterilization module 10 may include a plurality of sterilization modules 10. The plurality of sterilization modules 10 may be spaced apart and arranged along the first direction 12. Fig. 20For example, the plurality of sterilization modules 10 may include a first sterilization module 10a that emits a first light and a second sterilization module 10b that emits a second light. The first light of the first sterilization module 10a may have a first radiation angle A1 along the length direction (first direction 12) of the sterilization module 10. The second light of the second sterilization module 10b may have a second radiation angle A2 along the length direction (first direction 12) of the sterilization module 10. At this time, the first radiation angle A1 and the second radiation angle A2 may overlap at least a part. The first radiation angle A1 and the second radiation angle A2 may be adjusted by the reflective plate 180. The filter F may include: a first area facing the first sterilization module 10a; a second area facing the second sterilization module 10b; and a third area arranged between the first area and the second area, not facing the first sterilization module 10a and the second sterilization module 10b. The first light of the first sterilization module 10a and the second light of the second sterilization module 10b may overlap in the third area of ​​the filter F. In the case of the sterilization module 10 of the embodiment of the present invention, the reflective plate 180 is arranged on the main body 100 that fixes the light guide 200, rather than the light guide 200. Therefore, when the length of the sterilization module 10 in the first direction 12 is less than the length of the filter F in the first direction 12, the reflective plate 180 or the reflective pattern 250 can be adjusted to radiate light exceeding the length of the sterilization module 10.

[0164] The radiation angles A1 and A2 of the sterilization module 10 along the first direction 12 can be adjusted by the reflection pattern 250 of the light guide 200. Fig. 9 , the reflective pattern 250 may include: a first surface 253a; and a second surface 253b extending in a direction forming a predetermined pattern angle A relative to the first surface 253a. The radiation angles A1 and A2 may increase as the pattern angle A increases. Thus, when the length of the sterilization module 10 is smaller than the length of the filter F to be sterilized, the pattern angle A may be increased to increase the radiation angles A1 and A2 in the length direction, so that the entire area of ​​the filter F can be sterilized.

[0165] On the contrary, when the sterilization object is smaller than the sterilization module 10, the radiation angles A1 and A2 can be adjusted to be narrower by reducing the pattern angle A, thereby improving the sterilization effect by concentrating the light emitted from the sterilization module 10 on the sterilization object and reducing the loss of light.

[0166] Reference Figure 6 and Fig.21 , the sterilization module 10 may have a radiation angle A3 along the circumferential direction of the light guide 200. Figure 6, the radiation angle A3 along the circumferential direction may be the angle between the light reflected from one end of the reflection pattern 250 and the light reflected from the other end of the reflection pattern 250 along the circumferential direction. The radiation angle A3 along the circumferential direction may be adjusted by the position of the reflection pattern 250 formed in the second curve section 240. As an example, the radiation angle A3 when the reflection pattern 250 is formed in the entire area of ​​the second curve section 240 (see Figure 6 ) may be greater than the radiation angle A3 when the reflective pattern 250 is formed in a part of the second curve section 240 (an area smaller than the entire area of ​​the second curve section 240). The sterilization module 10 can sterilize the entire area of ​​the filter F along the third direction 16 by adjusting the radiation angle A3 along the circumferential direction.

[0167] The sterilization module 10 can be configured at a position where the first distance L1 is greater than the second distance L2. Fig. 22 , the sterilization module 10 can be arranged at a position adjacent to the top plate 610 of the housing 600. The sterilization module 10 can be arranged at the upper end of the suction port 601 of the housing 600. In this case, refer to Fig.23 , the sterilization module 10 may be tilted to have a predetermined angle A4 relative to the top plate 610 of the housing 600. The sterilization module 10 may be tilted relative to the filter F. In the case where the bottom plate 120 of the sterilization module 10 is formed parallel to the top surface of the sterilization module 10, the sterilization module 10 and the filter F may have a tilt angle corresponding to the predetermined angle A4.
