Description

[Technical Field]

[0001] SUMMARY OF THE INVENTION Embodiments of the present invention relate to a mounting fixture and an airflow generating device. [Background technology]

[0002] An air treatment module that performs air treatment such as air sterilization is used as the airflow generation module. In the air treatment module, outside air is introduced into the interior of the air treatment module by operating a fan or the like, and the introduced air is treated using either ultraviolet light or ozone, etc. The treated air is then discharged to the outside of the air treatment module.

[0003] An airflow generating module such as this air treatment module can be used while installed on a wall such as a ceiling. For example, when the air treatment module is installed on a wall, the air treatment module operates a fan or the like to introduce air into the air treatment module from an environmental space adjacent to the wall surface of the wall. The air treatment module then processes the introduced air and discharges the processed air into the environmental space.

[0004] When an airflow generating module is used by being installed on a wall, it is required that the airflow generating module be easily installable on the wall of the environmental space, for example, by making the airflow generating module easily attachable to a mounting fixture installed on the wall.

DETAILED DESCRIPTION OF THE INVENTION

[0010] The mounting device (2) of this embodiment includes a mounting plate (21) and a frame member (22). The mounting plate (21) is disposed on the back surface (12) of the wall portion (10), and the frame member (22) is attached to the mounting plate (21) while being disposed on the wall surface (11) of the wall portion (10). When an airflow generating module (3) having an opening (55) to the outside is attached to the frame member (22), the airflow generating module (3) is activated to allow air to flow through the opening (55), generating an airflow in the environmental space (15) adjacent to the wall surface (11). The frame member (22) includes a bottom plate portion (31) against which the attached airflow generating module (3) abuts from the front side, and a protrusion (32) protruding from the bottom plate portion (31) toward the front side around the entire periphery. The protrusion (32) surrounds the outer periphery of the airflow generating module (3) attached to the frame member (22). The protrusion (32) has an inner peripheral surface (37) facing inward, and the inner peripheral surface (37) is formed with a slope that is positioned more toward the outer periphery as it approaches the protruding end, which makes it easy to install the airflow generation module (3) on the wall portion (10).

[0011] In this embodiment, when the airflow generating module (3) is attached to the frame member (22), the opening (55) of the airflow generating module (3) opens toward the outer periphery. When the airflow generating module (3) is attached to the frame member (22), the inner peripheral surface (37) of the protrusion (32) of the frame member (22) faces the opening (55) of the airflow generating module (3) from the outer periphery. As a result, in a configuration in which air is discharged from the opening (55) to the environmental space (15), the air discharged from the opening (55) can easily reach areas of the environmental space (15) that are far from the wall (10). Furthermore, in a configuration in which air is introduced from the environmental space (15) to the airflow generating module (3) through the opening (55), air can easily be introduced into the airflow generating module (3) from areas of the environmental space (15) that are far from the wall (10).

[0012] In this embodiment, when the airflow generation module (3) is attached to the frame member (22), the airflow generation module (3) protrudes toward the front side relative to the protruding end of the projection (32) of the frame member (22). In other words, even an airflow generation module (3) that protrudes toward the front side relative to the mounting fixture (2) can be appropriately installed on the wall portion (10).

[0013] In this embodiment, the protrusion length L0 of the protrusion 32 from the bottom plate 31 of the frame member 22 is 5 mm or more. This makes it easier for the air discharged from the opening 55 to reach areas of the environmental space 15 that are farther from the wall 10.

[0014] In this embodiment, when the airflow generation module (3) is attached to the frame member (22), the airflow generation module (3) is activated to discharge air from the interior of the airflow generation module (3) through the opening (55) into the environmental space (15). As a result, when the airflow generation module (3) serves as an air treatment module, the air that has been treated by the airflow generation module (3) is discharged from the opening (55) which serves as an outlet into the environmental space (15). Therefore, the airflow generation module (3) installed on the wall portion (10) can be used to treat the air in the environmental space (15), such as by sterilizing and deodorizing.

[0015] The airflow generation device (1) of this embodiment includes a mounting plate (21), a frame member (22), and an airflow generation module (3). The mounting plate (21) is disposed on the back surface (12) of the wall portion (10), and the frame member (22) is attached to the mounting plate (21) while being disposed on the wall surface (11) of the wall portion (10). The airflow generation module (3) has an opening (55) to the outside, and when the airflow generation module (3) is operated while attached to the frame member (22), air flows through the opening (55), generating an airflow in the environmental space (15) adjacent to the wall surface (11). The frame member (22) includes a bottom plate portion (31) against which the attached airflow generation module (3) abuts from the front side, and a protrusion (32) protruding from the bottom plate portion (31) toward the front side around the entire circumferential circumference. The protrusion (32) surrounds the airflow generating module (3) attached to the frame member (22) from the outer periphery. The protrusion (32) has an inner periphery surface (37) facing inward, and the inner periphery surface (37) is formed with a slope that is positioned more toward the outer periphery as it approaches the protruding end. This makes it easy to install the airflow generating module (3) on the wall portion (10).

[0016] Hereinafter, embodiments will be described with reference to the drawings.

[0017] First, as an example of an embodiment, a case where an air treatment device is used as an airflow generating device will be described. FIG. 1 is a perspective view of an example of an air treatment device 1 according to an embodiment. As shown in FIG. 1, the air treatment device 1 includes a mounting fixture 2, an air treatment module 3 serving as an airflow generating module, and a power supply unit 5. The mounting fixture 2 is installed on a wall, and the air treatment module 3 can be attached to the mounting fixture 2 installed on the wall. The air treatment module 3 is installed on the wall by attaching it to the mounting fixture 2 installed on the wall. The mounting fixture 2 and the air treatment module 3 are installed on walls such as the ceiling wall and side walls in an environmental space such as a room. In the following description, the combination of the mounting fixture 2 and the air treatment module 3 is also referred to as an "air treatment assembly" and an "airflow generating assembly."

[0018] In the air treatment assembly and mounting fixture 2, a central axis C is defined. In the air treatment assembly and mounting fixture 2, the direction along the central axis C (the direction indicated by arrows C1 and C2) is defined as the axial direction, and the direction around the central axis C is defined as the circumferential direction. In the air treatment assembly and mounting fixture 2, the direction intersecting (perpendicular or nearly perpendicular to) both the axial and circumferential directions is defined as the radial direction. In the air treatment assembly and mounting fixture 2, the side closer to the central axis C in the radial direction is the inner circumferential side, and the side away from the central axis C in the radial direction is the outer circumferential side. In the air treatment assembly and mounting fixture 2, the axial direction is also referred to as the "height direction."

[0019] FIG. 2 is a cross-sectional view showing the state in which the mounting fixture 2 and the air treatment module 3 are installed on a wall 10, i.e., the state in which an air treatment assembly, which is a combination of the mounting fixture 2 and the air treatment module 3, is installed on the wall 10. In FIG. 2, the mounting fixture 2 and the air treatment assembly are shown in cross section along the axial direction. The wall 10 on which the air treatment assembly is installed has a wall surface 11 and a wall back surface 12. In the wall 10, the wall surface 11 and the wall back surface 12 face opposite each other. In the wall 10, the wall surface 11 faces the side where an environmental space 15, such as a room, is located, and the wall back surface 12 faces the side opposite the side where the environmental space 15 is located. In addition, in the wall 10, the wall surface 11 is adjacent to the environmental space 15.

[0020] Here, in the wall 10 and the mounting fixture 2, air treatment assembly, etc. installed on the wall 10, the side to which the wall surface 11 faces, i.e., the side to which the environmental space 15 is located, corresponds to the front side (arrow C1 side). In the wall 10 and the mounting fixture 2, air treatment assembly, etc. installed on the wall 10, the side to which the wall back surface 12 faces, i.e., the side opposite to the side to which the environmental space 15 is located, corresponds to the back side (arrow C2 side). The front side is also referred to as the "front side" or "front surface side," and the back side is also referred to as the "rear side" or "rear surface side."

[0021] A wall hole 13 is formed in the wall 10 on which the mounting fixture 2 is to be installed, and the wall hole 13 penetrates the wall 10 from the wall surface 11 to the wall back surface 12. The mounting fixture 2 and the air treatment assembly are installed in the wall 10 at the wall hole 13. The mounting fixture 2 and the air treatment assembly are installed on the wall 10 so that one axial side of the mounting fixture 2 and the air treatment assembly coincides or approximately coincides with the front side, and the other axial side of the mounting fixture 2 coincides or approximately coincides with the back side. In one example, such as FIG. 2 , the mounting fixture 2 and the air treatment assembly are installed on the wall 10 so that the central axis C of the mounting fixture 2 is coaxial or approximately coaxial with the central axis of the wall hole 13. In one example, the mounting fixture 2 and the air treatment assembly are installed on a ceiling wall that serves as the wall 10 so that the axial direction of the mounting fixture 2 is aligned vertically. In this case, the front side coincides or approximately coincides with the vertically lower side, and the back side coincides or approximately coincides with the vertically upper side.

[0022] Fig. 3 shows a perspective view of the mounting fixture 2 according to the embodiment, and Fig. 4 shows a cross-sectional view of the embodiment in which only the mounting fixture 2 is installed on a wall 10. In Fig. 4, the mounting fixture 2 is shown in cross section along the axial direction. As shown in Figs. 1 to 4, the mounting fixture 2 comprises a mounting plate 21 and a frame member (decorative frame) 22. When the mounting fixture 2 is installed on the wall 10, the mounting plate 21 is disposed on the rear wall surface 12 of the wall 10, and is disposed on the back side of the wall 10. Furthermore, the mounting plate 21 abuts against the rear wall surface 12 of the wall 10 from the back side.

[0023] The mounting plate 21 is formed in a plate shape, and a thickness direction of the mounting plate 21 is defined. In the mounting fixture 2, the thickness direction of the mounting plate 21 is along the axial direction (center axis C) of the mounting fixture 2. The mounting plate 21 is formed with a plate hole 23 penetrating the mounting plate 21 in the thickness direction (axial direction of the mounting fixture 2). The central axis of the plate hole 23 is coaxial or approximately coaxial with the central axis C of the mounting fixture 2. The mounting plate 21 surrounds the plate hole 23 from the outer periphery over the entire circumferential direction, and the peripheral surface of the plate hole 23 is formed by the mounting plate 21. In one example such as FIG. 4 , the mounting fixture 2 is installed on the wall portion 10 with the central axis of the plate hole 23 being coaxial or approximately coaxial with the central axis of the wall hole 13. When the mounting fixture 2 is installed on the wall portion 10, the plate hole 23 of the mounting plate 21 faces the wall hole 13 of the wall portion 10 from the back side.

[0024] In the mounting device 2, guide screws 25 and connecting screws 26 are attached to the mounting plate 21. For example, a plurality of guide screws 25 and connecting screws 26 are attached to the mounting plate 21. The guide screws 25 and connecting screws 26 are located on the outer periphery of the plate holes 23 of the mounting plate 21. The guide screws 25 and connecting screws 26 are also spaced apart from each other in the circumferential direction (the direction around the central axis C). When the mounting device 2 is installed on the wall 10, each of the guide screws 25 is inserted into the wall holes 13 from the back side. When the mounting device 2 is installed on the wall 10, each of the connecting screws 26 extends from the mounting plate 21 toward the front side, passing through the wall holes 13.

[0025] In the mounting device 2, the frame member 22 is attached to the mounting plate 21 via connecting screws 26. One end of each of the connecting screws 26 is connected to the mounting plate 21, and the other end is connected to the frame member 22. In the mounting device 2, the frame member 22 is attached to the mounting plate 21 while being spaced apart from the mounting plate 21 in the axial direction. In the mounting device 2, the connecting screws 26 make it possible to adjust the axial separation distance between the mounting plate 21 and the frame member 22.

[0026] When the mounting fixture 2 is installed on the wall 10, the frame member 22 is disposed on the wall surface 11 of the wall 10, and is disposed on the front side of the wall 10. The frame member 22 abuts against the wall surface 11 of the wall 10 from the front side. Therefore, in the mounting fixture 2 installed on the wall 10, the frame member 22 is attached to the mounting plate 21 with the front side separated from the mounting plate 21. When the mounting fixture 2 is installed on the wall 10, the frame member 22 is exposed in the environmental space 15. The frame member 22 installed on the wall 10 protrudes from the wall surface 11 of the wall 10 toward the front side, i.e., toward the environmental space 15.

[0027] When the mounting device 2 is installed on the wall 10, each of the connecting screws 26 extends between the mounting plate 21 and the frame member 22 and passes through the wall holes 13. When the mounting device 2 is installed on the wall 10, the wall 10 is sandwiched between the mounting plate 21 and the frame member 22. In the mounting device 2, the distance between the mounting plate 21 and the frame member 22 is adjusted by the connecting screws 26 in accordance with the thickness of the wall 10, i.e., the distance between the wall front surface 11 and the wall back surface 12 of the wall 10.

[0028] The frame member 22 includes a bottom plate portion 31 and a protrusion 32. In the mounting device 2 installed on the wall portion 10, the bottom plate portion 31 of the frame member 22 abuts against the wall surface 11 of the wall portion 10 from the front side. In addition, in the frame member 22, the protrusion 32 protrudes from the bottom plate portion 31 on the side opposite to the side on which the mounting plate 21 is located in the axial direction. Therefore, in the frame member 22 installed on the wall portion 10, the protrusion 32 protrudes from the bottom plate portion 31 toward the front side and from the bottom plate portion 31 toward the environmental space 15. The protrusion 32 is connected to the outer peripheral end of the bottom plate portion 31 and protrudes from the outer peripheral end of the bottom plate portion 31. In addition, the protrusion 32 is formed around the entire circumferential circumference and protrudes from the bottom plate portion 31 around the entire circumferential circumference.

[0029] The bottom plate portion 31 of the frame member 22 is formed in a plate shape, and the plate thickness direction is defined by the bottom plate portion 31. In the mounting fixture 2, the plate thickness direction of the bottom plate portion 31 of the frame member 22 is aligned with the axial direction (center axis C) of the mounting fixture 2. The mounting plate 21 is formed with a frame hole 33 that penetrates the bottom plate portion 31 in the plate thickness direction (axial direction of the mounting fixture 2). The center axis of the frame hole 33 is coaxial or approximately coaxial with the center axis C of the mounting fixture 2. The bottom plate portion 31 also surrounds the frame hole 33 from the outer periphery over the entire circumferential direction, and the circumferential surface of the frame hole 33 is formed by the bottom plate portion 31. In one example such as FIG. 4 , the mounting fixture 2 is installed on the wall portion 10 with the center axis of the frame hole 33 being coaxial or approximately coaxial with the center axis of the wall hole 13. Furthermore, when the mounting fixture 2 is installed on the wall portion 10, the frame hole 33 of the bottom plate portion 31 of the frame member 22 faces the wall hole 13 of the wall portion 10 from the front side.

[0030] In the frame member 22, each of the connection screws 26 is connected to the bottom plate portion 31. In addition, in the frame member, the protrusions 32 are arranged on the outer peripheral side of the frame holes 33. The protrusions 32 surround the frame holes 33 from the outer peripheral side over the entire circumferential circumference. The connection screws 26 are arranged between the frame holes 33 and the protrusions 32 in the radial direction of the mounting device 2. Therefore, the connection screws 26 are located on the outer peripheral side of the frame holes 33 of the bottom plate portion 31, and on the inner peripheral side of the protrusions 32 of the frame member 22.

[0031] In the frame member (decorative frame) 22, the protrusion 32 has a protrusion end face 35, a protrusion outer peripheral face 36, and a protrusion inner peripheral face 37. In the frame member 22, the protrusion end face 35, the protrusion outer peripheral face 36, and the protrusion inner peripheral face 37 are each formed around the entire circumferential direction. The protrusion end face 35 forms the protruding end of the protrusion 32 and faces the side opposite to the side on which the mounting plate 21 is located. Therefore, in the frame member 22 installed on the wall portion 10, the protrusion end face 35 of the protrusion 32 faces the front side, that is, faces the side on which the environmental space 15 is located.

[0032] Furthermore, in the protrusion 32, the protrusion outer peripheral surface 36 and the protrusion inner peripheral surface 37 each extend from the connection position with the bottom plate portion 31 to the protrusion end surface 35. That is, in the protrusion 32, the protrusion outer peripheral surface 36 and the protrusion inner peripheral surface 37 each extend from the base of the protrusion to the protrusion end. In the protrusion 32, the protrusion outer peripheral surface 36 faces the outer periphery, and the protrusion inner peripheral surface 37 faces the inner periphery. Furthermore, the protrusion outer peripheral surface 36 extends along the axial direction of the mounting device 2 and is parallel or approximately parallel to the axial direction (center axis C) of the mounting device 2. Therefore, the protrusion outer peripheral surface 36 is not inclined with respect to the axial direction of the mounting device 2.

[0033] The protrusion inner peripheral surface 37 is inclined relative to the axial direction (central axis C) of the mounting device 2, and has a gradient relative to the axial direction of the mounting device 2. The protrusion inner peripheral surface 37 is formed with a gradient that is more radially outward the closer it is to the protrusion end (protrusion end surface 35). Therefore, in the frame member 22 installed on the wall portion 10, the protrusion inner peripheral surface 37 of the protrusion 32 is inclined relative to the axial direction of the mounting device 2 with a gradient that is more radially outward the closer it is to the front side. The protrusion inner peripheral surface 37 is formed with the aforementioned gradient over the entire circumferential direction.

[0034] Furthermore, in the frame member 22, a protrusion length L0 of the protrusion 32 from the bottom plate portion 31 is defined. In the frame member 22 installed on the wall portion 10, the distance toward the front side from the connection portion of the protrusion 32 to the bottom plate portion 31 to the protruding end face 35 corresponds to the protrusion length L0. The protrusion length L0 of the protrusion 32 is set to 5 mm or more, and in one example, the protrusion length L0 is about 10 mm.

[0035] 1 and 2, the air treatment module 3, which is an airflow generating module, is attached to the mounting fixture 2 in a state where it is inserted through the plate hole 23 of the mounting plate 21 and the frame hole 33 of the frame member 22. When the air treatment assembly including the air treatment module 3 is installed on the wall portion 10, the air treatment module 3 protrudes from the mounting plate 21 to the rear side, and a part of the air treatment module 3 is embedded in the rear side of the wall surface 11.

[0036] Furthermore, when the air treatment module 3 is attached to the mounting fixture 2, the air treatment module 3 protrudes from the protruding end (protruding end surface 35) of the protrusion 32 of the frame member 22, on the side opposite to the side on which the mounting plate 21 is located. Therefore, when the air treatment assembly is installed on the wall 10, the air treatment module 3 protrudes from the protruding end of the protrusion 32 of the frame member 22 toward the front side, and protrudes toward the side on which the environmental space 15 is located. Then, in the air treatment module 3 installed on the wall 10, the part that protrudes from the protrusion 32 of the frame member 22 toward the front side is exposed in the environmental space 15.

[0037] Here, in the air treatment module 3 shown in Figures 1 and 2, etc., the height direction is defined. In the air treatment module 3, one side in the height direction is the upper side, and the side opposite the upper side in the height direction is the lower side. The air treatment module 3 is attached to the mounting fixture 2 with the height direction aligned with the axial direction of the mounting fixture 2. In the air treatment module 3 attached to the wall 10, the lower side of the air treatment module 3 coincides or nearly coincides with the front side, and the upper side of the air treatment module 3 coincides or nearly coincides with the back side. In addition, in the air treatment module 3 attached to the wall 10, the circumferential and radial directions are defined in the same way as in the mounting fixture 2, etc., and the inner and outer peripheral sides are defined in the same way as in the mounting fixture 2, etc.

[0038] The air treatment module 3 is installed on the wall 10 while being inserted through the wall hole 13. In the mounting fixture 2 installed on the wall 10, the guide screw 25 is inserted into the wall hole 13 from the back side. When installing the air treatment module 3 on the wall 10, the air treatment module 3 can be moved past the wall hole 13 to the back side only when the angular position of the air treatment module 3 in the circumferential direction is at a predetermined angular position. Therefore, the air treatment module 3 can be attached to the mounting fixture 2 and installed on the wall 10 only when the angular position of the air treatment module 3 in the circumferential direction is at a predetermined angular position. Therefore, when installing the air treatment module 3 on the wall 10, the angular position of the air treatment module 3 in the circumferential direction is adjusted by the guide screw 25 to be at a predetermined angular position.

[0039] The air treatment module 3 includes an exterior housing 40 that forms the exterior, and in the air treatment module 3, an internal cavity is formed inside the exterior housing 40. The exterior housing 40 includes a lower plate portion 41, an upper plate portion 42, a peripheral plate portion 43, and a flange portion 45. In the air treatment module 3, the lower plate portion 41 covers the internal cavity from below, and the upper plate portion 42 covers the internal cavity from above. Therefore, the upper plate portion 42 faces the lower plate portion 41, with the internal cavity of the exterior housing 40 sandwiched between them. In the air treatment module 3 installed on the wall portion 10, the lower plate portion 41 covers the internal cavity from the front side, and the upper plate portion 42 covers the internal cavity from the back side.

[0040] The peripheral plate portion 43 extends in the height direction between the lower plate portion 41 and the upper plate portion 42, and the upper end of the peripheral plate portion 43 is connected to the upper plate portion 42. The peripheral plate portion 43 covers the internal cavity from the outer periphery, covering the internal cavity over the entire circumferential direction. The lower end of the peripheral plate portion 43 is connected to the flange portion 45, and in the exterior housing 40, the flange portion 45 is connected to the lower plate portion 41 from the outer periphery. In the exterior housing 40, the flange portion 45 protrudes outward from the peripheral plate portion 43, and protrudes outward over the entire circumferential direction.

[0041] In the air treatment module 3 and air treatment assembly installed on the wall 10, the lower plate 41 and flange 45 are located on the front side relative to the wall surface 11 of the wall 10, and the upper plate 42 is located on the back side relative to the back surface 12 of the wall 10 and the mounting plate 21. When the air treatment assembly is installed on the wall 10, the peripheral plate 43 extends from the front side through the frame hole 33 of the frame member 22, the wall hole 13 of the wall 10, and the plate hole 23 of the mounting plate 21, in that order, and extends along the axial direction of the air treatment assembly. In addition, in the air treatment module 3 installed on the wall 10, the lower plate 41, flange 45, etc. are exposed in the environmental space 15.

[0042] When the air treatment module 3 is installed on the wall 10, the flange 45 of the exterior housing 40 abuts against the bottom plate 31 of the frame member 22 from the front side. In the air treatment assembly installed on the wall 10, the flange 45 and the lower plate 41 of the exterior housing 40 are disposed on the inner periphery of the protrusion 32 of the frame member 22, and the protrusion 32 of the frame member 22 surrounds the flange 45 and the lower plate 41 of the exterior housing 40 from the outer periphery over the entire circumferential direction. Therefore, the protrusion 32 surrounds the air treatment module 3 from the outer periphery over the entire circumferential direction. In addition, in the air treatment assembly installed on the wall 10, the protrusion inner periphery 37 of the protrusion 32 of the frame member 22 faces the flange 45 of the exterior housing 40 from the outer periphery. In the air treatment assembly, the protrusion inner periphery 37 of the protrusion 32 faces the flange 45 from the outer periphery over the entire circumferential direction.

[0043] Furthermore, in the air processing assembly installed on the wall 10, the flange 45 of the exterior housing 40 does not contact the protrusion 32 of the frame member 22, and a gap is formed between the protrusion 32 and the flange 45 in the radial direction. The gap between the protrusion 32 and the flange 45 is formed over the entire circumferential direction. Furthermore, in the air processing assembly installed on the wall 10, the flange 45 etc. of the exterior housing 40 protrudes toward the front side relative to the protruding end (protruding end surface 35) of the protrusion 32 of the frame member 22, and protrudes toward the side where the environmental space 15 is located in the axial direction.

[0044] 1 and other figures, in the exterior housing 40, a plurality of spring members 76 are attached to the outer surface of the peripheral plate portion 43. When installing the air treatment module 3 on the wall portion 10, the force generated by the spring members 76 is used to move the air treatment module 3 to the rear side through the wall holes 13 and the like. In the air treatment module 3 installed on the wall portion 10, the spring members 76 extend through the plate holes 23 of the mounting plate 21 and come into contact with the rear wall surface 12 of the wall portion 10.

[0045] 1 and 2, in the air treatment module 3, a visible light source module 50 is attached to a lower plate 41 of an exterior housing 40. The visible light source module 50 is attached to the lower plate 41 from below in the height direction, and attached to the lower plate 41 from the front side. The visible light source module 50 is disposed outside the exterior housing 40, on the outer surface of the lower plate 41. A gap is formed between the lower plate 41 of the exterior housing 40 and the visible light source module 50. The visible light source module 50 is disposed on the inner periphery of a flange 45 of the exterior housing 40, and the flange 45 surrounds the visible light source module 50 from the outer periphery all around.

[0046] Visible light source module 50 includes light source housing 51, visible light source 52, and cover member 53. In visible light source module 50, visible light source 52 is arranged in the internal space of light source housing 51. Cover member 53 is attached to light source housing 51 from the side opposite to the side on which exterior housing 40 is located. In air treatment module 3, cover member 53 covers the internal space of light source housing 51 from the lower side (front side) in the height direction.

[0047] In the visible light source module 50, visible light source 52 is activated by the supply of power, causing visible light to be emitted from visible light source 52. Visible light source 52 emits visible light downward in the height direction, i.e., toward the front side. The visible light from visible light source 52 passes through cover member 53 and is emitted to the outside of light source housing 51. In the air treatment module 3 installed on the wall 10, the visible light source module 50 is exposed in environmental space 15. The visible light from visible light source 52 passes through cover member 53 and is irradiated into environmental space 15.

[0048] The exterior housing 40 also has openings 55 and 56 to the outside. The opening (first opening) 55 is formed in the flange portion 45, and the opening (second opening) 56 is formed in the lower plate portion 41. In the exterior housing 40, the internal cavity opens to the outside at each of the openings 55 and 56. When the air treatment module 3 is attached to the mounting fixture 2 including the frame member 22, the opening 55 is located on the outer periphery side of the opening 56. In the air treatment assembly, the openings 55 and 56 are located on the inner periphery side of the protrusion 32 of the frame member 22. In the air treatment module 3 installed on the wall portion 10, the internal cavity opens to the environmental space 15 at each of the openings 55 and 56.

[0049] In the air treatment assembly, the opening (first opening) 55 opens toward the outer periphery. The protrusion 32 of the frame member 22 faces the opening 55 from the outer periphery. Therefore, in the air treatment assembly in which the air treatment module 3 is attached to the mounting fixture 2, the protrusion inner circumferential surface 37 of the protrusion 32 faces the opening 55 of the air treatment module 3 from the outer periphery. In the air treatment assembly, a gap is formed between the opening 55 and the protrusion 32 in the radial direction, and the opening 55 opens toward the gap between the protrusion 32 of the frame member 22 and the flange portion 45 of the exterior housing 40.

[0050] In the air treatment module 3, the opening (second opening) 56 opens downward in the height direction. The opening 56 opens toward the gap between the lower plate 41 of the exterior housing 40 and the visible light source module 50. In the air treatment assembly installed on the wall 10, the opening 56 opens toward the front side.

[0051] 2 and other figures, an internal frame 61 is disposed inside (inner cavity) the exterior housing 40. The internal frame 61 abuts against the lower plate portion 41 from the upper side (rear side) in the height direction. Inside the exterior housing 40, a space 62 surrounded by the internal frame 61 and the lower plate portion 41 is formed. The space 62 opens to the outside of the exterior housing 40 through an opening 56 in the lower plate portion 41, and opens at the opening 56 toward the lower side in the height direction (front side).

[0052] Furthermore, inside the exterior housing 40, a space 63 is formed between the upper plate portion 42 and the internal frame 61 in the height direction, and a space 65 is formed between the peripheral plate portion 43 and the internal frame 61 in the radial direction. A hole 66 is formed in the internal frame 61, and the space 62 communicates with the space 63 through the hole 66. Furthermore, the space 65 is separated from the space 62 by the internal frame 61. The space 65 opens to the outside of the exterior housing 40 through the opening 55, and opens toward the outer periphery at the opening 55. Due to the configuration as described above, inside the exterior housing 40, the opening 55 communicates with the opening 56 only by passing through the space 65, the space 63, and the space 62 in this order.

[0053] A fan 71 is disposed in the space 63 inside the exterior housing 40 (inside the air treatment module 3). In one example shown in FIG. 2 etc., the fan 71 is a centrifugal fan. When the air treatment module 3 is installed on the wall 10, the fan 71 is operated by supplying power, and air is introduced from the environmental space 15 into the space 62 inside the exterior housing 40 through the opening 56 (arrow A1). Then, inside the exterior housing 40, air flows from the space 62 into the space 63, and then flows into the fan 71 from the lower side (front side) in the height direction (arrow A2). Then, air flows out from the fan 71 toward the outer periphery, and air flows from the space 63 into the space 65 (arrow A3). Then, air is discharged from the space 65 inside the exterior housing 40 through the opening 55 into the environmental space 15 (arrow A4).

[0054] The operation of the fan 71 forms the air flow described above, and therefore, when the fan 71 is operating, air flows through the openings 55 and 56. At this time, inside the air treatment module 3 (inside the exterior housing 40), air flows from the opening 56 toward the opening 55. The opening 56 serves as an inlet (air intake) that introduces air into the interior of the exterior housing 40, and the opening 55 serves as an outlet that discharges air from the interior of the exterior housing 40. Furthermore, when the fan 71 of the air treatment module 3 is operated, air flows through the openings 55 and 56 as described above, generating an air current in the environmental space 15.

[0055] Furthermore, inside the exterior housing 40, an ultraviolet light source 72 and a photocatalyst module 73 are arranged in a space 62. In the space 62, the photocatalyst module 73 is arranged above (at the rear of) the ultraviolet light source 72 in the height direction. When the ultraviolet light source 72 is activated by supplying power, the ultraviolet light source 72 emits ultraviolet light. In one example, such as FIG. 2, the ultraviolet light source 72 emits ultraviolet light toward the upper side in the height direction. The ultraviolet light source 72 is provided with a light-emitting element, and the light-emitting element is, for example, an ultraviolet LED. Furthermore, instead of a light-emitting element, the ultraviolet light source 72 may be a lamp other than an LED, such as a mercury lamp, a metal halide lamp, a fluorescent ultraviolet lamp, or an excimer lamp.

[0056] In the photocatalyst module 73, a photocatalyst is supported on the surface of a base material. In the photocatalyst module 73, a plurality (countless) of through holes are formed in the base material, and the base material is made of ceramics such as aluminum oxide and aluminum nitride. The photocatalyst supported on the base material is made of metal oxides such as titanium oxide and tungsten oxide.

[0057] In the example shown in FIG. 2 , air treatment is performed using ultraviolet light emitted from an ultraviolet light source 72 and a photocatalyst module 73. The ultraviolet light source 72 emits ultraviolet light with a peak wavelength in the range of 320 nm or more and 400 nm or less, i.e., UV-A, into the space 62. At least a portion of the ultraviolet light emitted from the ultraviolet light source 72 enters the photocatalyst module 73 directly and / or after reflection. When the UV-A enters the photocatalyst module 73, active oxygen and OH radicals are generated in the photocatalyst module 73. The generated active oxygen and OH radicals then decompose viruses, fungi (bacteria), odorous substances, and the like contained in the air flowing toward the opening 55 (exhaust port). This allows sterilization and deodorization of the air inside the exterior housing 40. The air that has undergone air treatment, such as sterilization and deodorization, is then discharged from the opening 55 to the environmental space 15.

[0058] In one example, the ultraviolet light source 72 emits ultraviolet light having a peak wavelength in the range of 200 nm or more and 320 nm or less, i.e., UV-C, in addition to the aforementioned UV-A, into the space 62. In the space 62, the ultraviolet light source 72 irradiates the air with UV-C, thereby suppressing the activity of viruses and bacteria (germs) contained in the air flowing through the space 62. This sterilizes the air inside the exterior housing 40.

[0059] Note that "sterilization" means inactivating viruses and bacteria (bacteria) present in the air, and terms such as "disinfection," "sterilization," and "sterilization" can be used instead of "sterilization." Therefore, although the term "sterilization" is used in the embodiments, the term "sterilization" can be replaced with "sterilization," "sterilization," and "sterilization."

[0060] In one example, air treatment may only involve sterilizing the air using UV-C. When air treatment is performed using ultraviolet light from the ultraviolet light source 72, it is preferable that at least the inner surface of the internal frame 61 and the inner surface of the lower plate 41 of the exterior housing 40 be formed from a material that has a high reflectivity for ultraviolet light. In this case, examples of materials that can be used to form the inner surface of the internal frame 61 and the inner surface of the lower plate 41 include aluminum alloys and stainless steel alloys. Forming the inner surface of the internal frame 61 and the inner surface of the lower plate 41 of the exterior housing 40 from a material that has a high reflectivity for ultraviolet light effectively prevents ultraviolet light from being emitted outside the exterior housing 40.

[0061] In one example, instead of or in addition to the air treatment using ultraviolet light described above, air treatment using ozone is performed. In this case, an ozone generator is disposed inside the exterior housing 40. Inside the exterior housing 40, air treatment is performed by mixing ozone with air flowing from the opening 56 (inlet) toward the opening 55 (outlet). The air mixed with ozone is then discharged to the outside of the exterior housing 40 through the opening 55. In this case, the ozone discharged from inside the exterior housing 40 into the environmental space 15 performs at least one of sterilization and deodorization of the air.

[0062] 1 and other figures, in the air treatment device 1, which is an airflow generating device, the power supply unit 5 is connected to the air treatment module 3 via a cable 75. The power supply unit 5 supplies power to the air treatment module 3 through the cable 75. The visible light source 52, the fan 71, and the ultraviolet light source 72 are each operated by the power from the power supply unit 5. The power supply unit 5 is also disposed on the back side of the wall 10, for example, on the back surface 12 of the wall 10.

[0063] As described above, in the mounting device 2 of this embodiment, the mounting plate 21 is disposed on the rear wall surface 12 of the wall portion 10, and the frame member 22 is attached to the mounting plate 21 while being disposed on the wall surface 11 of the wall portion 10. Furthermore, in the frame member 22, the protrusions 32 protrude from the bottom plate portion 31 toward the front side along the entire circumferential direction, and the air treatment module 3 is attached to the frame member 22 while abutting against the bottom plate portion 31 from the front side. The protrusions 32 of the frame member 22 surround the attached air treatment module 3 from the outer periphery. With this configuration, the air treatment module 3 can be easily attached to the mounting device 2 while being surrounded by the protrusions 32 of the frame member 22. This makes it possible to easily install the air treatment module 3, which is an airflow generating module, on the wall portion 10.

[0064] In this embodiment, the protrusion 32 of the frame member 22 includes a protrusion inner peripheral surface 37, which is sloped so that the closer to the protruding end of the protrusion 32, the more radially outward the protrusion. With this configuration, even if light from a lighting fixture or the like enters the gap between the air treatment module 3 and the protrusion 32 of the frame member 22 from the environmental space 15, the incident light is easily reflected by the protrusion inner peripheral surface 37 toward the environmental space 15. Therefore, the light that enters the gap between the air treatment module 3 and the protrusion 32 of the frame member 22 is less likely to reach the bottom plate portion 31 that forms the bottom of the gap. This makes the gap between the air treatment module 3 and the protrusion 32 of the frame member 22 less noticeable when the air treatment assembly installed on the wall 10 in the environmental space 15 is viewed. This improves the aesthetic appearance of the air treatment assembly installed on the wall 10.

[0065] Furthermore, in this embodiment, by operating the air treatment module 3 installed on the wall 10, air flows through the openings 55 and 56, generating an airflow in the environmental space 15. When the air treatment module 3 is operating, air is introduced from the environmental space 15 into the air treatment module 3 through the opening 56, which serves as an inlet, and the treated air is discharged into the environmental space 15 from the opening 55, which serves as an outlet. This makes it possible to perform air treatment such as sterilization and deodorization in the environmental space 15 using the air treatment module 3 installed on the wall 10.

[0066] Furthermore, in this embodiment, the opening 55 serving as an exhaust port opens toward the outer periphery, and when the air treatment module 3 is attached to the frame member 22, the inner peripheral surface 37 of the protrusion 32 of the frame member 22 faces the opening 55 from the outer periphery. Therefore, in the environmental space 15, the inner peripheral surface 37 of the protrusion 32 makes it difficult for air to flow from the opening 55 along the wall surface 11, and makes it easier for air to flow from the opening 55 away from the wall 10. This makes it easier for the air discharged from the opening 55, i.e., the air that has been treated, to reach areas away from the wall 10 in the environmental space 15. For example, when the air treatment module 3 is installed on the ceiling wall of the environmental space 15, the treated air can easily reach areas away from the ceiling wall that forms the wall 10, i.e., areas close to the floor. This improves the air treatment performance in the environmental space 15.

[0067] Furthermore, in one example of this embodiment, the protrusion length L0 of the protrusion 32 from the bottom plate portion 31 in the frame member 22 is 5 mm or more. With this configuration, the protrusion inner peripheral surface 37 more easily generates an air flow from the opening 55 that flows away from the wall portion 10. This makes it easier for the air that has been subjected to air treatment in the environmental space 15 to reach areas that are farther away from the wall portion 10, further improving the air treatment performance in the environmental space 15.

[0068] FIG. 5 is a schematic diagram illustrating an example of an air flow formed in the environmental space 15 when the air treatment module 3 installed on the wall 10 is in operation in this embodiment. In this embodiment, the opening 56 serving as an inlet in the air treatment module 3 faces the front side, and the opening 56 is located on the inner circumferential side relative to the opening 55 serving as an outlet. Because of this configuration, as shown in FIG. 5 and other figures, when the air treatment module 3 is operated, air flows toward the air treatment module 3 (air treatment assembly) in the environmental space 15 along a direction perpendicular or substantially perpendicular to the wall surface 11 (arrow F1). In the environmental space 15, air flows into the air treatment module 3 from a region α1 that is not shifted or is barely shifted from the air treatment module 3 in the direction along the wall surface 11.

[0069] In one example, the air treatment module 3 is installed with its height direction aligned vertically on the ceiling wall that is the wall portion 10. In this case, by operating the air treatment module 3, air flows from the vertically downward direction in the environmental space 15 toward the air treatment module 3, and air flows into the air treatment module 3 from the region directly below the air treatment module 3, i.e., a region that is not or barely offset horizontally from the air treatment module 3.

[0070] In this embodiment, the protrusion 32 of the frame member 22 faces the opening 55, which serves as an exhaust port, from the outer periphery, and the protrusion inner periphery 37 of the protrusion 32 has the slope described above. Therefore, by operating the air treatment module 3, air flows from the opening 55 in the environmental space 15 away from the wall 10, and the air discharged from the opening 55 flows in a direction inclined relative to the wall surface 11 (arrow F2). At this time, the air discharged from the opening 55 flows in a manner that spreads more toward the outer periphery of the air treatment assembly (mounting fixture 2) as it moves away from the wall 10 (wall surface 11). Because the air discharged from the opening 55 flows as described above, the air discharged from the opening 55, i.e., the air that has been air-treated, flows in the environmental space 15 in a manner that surrounds the periphery (outer periphery) of the region α1 through which air flows toward the air treatment module 3.

[0071] 5, the air that has undergone air processing flows as described above, so that in environmental space 15, the inflow of air from the surrounding (outer periphery) region α2 into region α1 is suppressed by the flow of air discharged from opening 55. At this time, the flow of air discharged from opening 55 functions as a so-called "air curtain," thereby suppressing the inflow of air from region α2 into region α1. Then, with the inflow of air from region α2 to region α1 suppressed, air circulates within region α2 (arrow F3).

[0072] In this embodiment, operation of the air treatment module 3 forms an air flow in the environmental space 15 similar to the example shown in Fig. 5. This prevents air from flowing in from the outer periphery into the region α1 where air flows toward the air treatment module 3, i.e., into the region where sterilization and other processes are being performed. This effectively prevents air containing viruses, germs (bacteria), and the like from flowing into the region α1 where sterilization and other processes are being performed. This further improves the air treatment performance in the environmental space 15, including the sterilization performance and other processes of the environmental space 15.

[0073] In this embodiment, the direction in which the air discharged from the opening 55 flows from the air treatment module 3 changes depending on the gradient angle (tilt angle) of the protrusion inner peripheral surface 37 of the protrusion 32 of the frame member 22. That is, by adjusting the gradient angle of the protrusion inner peripheral surface 37, the tilt state of the flow direction of the discharged air relative to the wall surface 11 is adjusted. By adjusting the flow direction of the discharged air from the air treatment module 3, the area α1 through which the air flows toward the air treatment module 3, i.e., the size of the area where sterilization, etc. is being performed, is adjusted.

[0074] Furthermore, in one example of this embodiment, when the air treatment module 3 is attached to the frame member 22, the air treatment module 3 protrudes toward the front side relative to the protruding end of the protrusion 32 of the frame member 22. That is, in the embodiment, an air treatment module 3 that protrudes toward the front side relative to the mounting fixture 2 can also be appropriately installed on the wall portion 10. Furthermore, by forming an opening 56 that serves as an inlet in the air treatment module 3, for example, in the part that protrudes relative to the protruding end of the protrusion 32, air can be more appropriately introduced from the environmental space 15 into the interior of the air treatment module 3. This further improves the air treatment performance in the environmental space 15.

[0075] In the above-described embodiment, the air treatment module 3 that performs air treatment is attached to the mounting fixture 2 as an airflow generation module, but this is not limited to this. In one variation, a ventilation module such as a ventilator fan is attached to the mounting fixture 2 as an airflow generation module and installed on the wall 10. In this variation, the ventilation module, the mounting fixture 2, and the power supply unit 5 form a ventilation device that is an airflow generation device. Then, a ventilation assembly that is an airflow generation assembly is formed by connecting the ventilation module to the mounting fixture 2.

[0076] In this modification, an opening (first opening) 55 is formed in the ventilation module, as in the above-described embodiment, and in a ventilation module installed on a wall 10, the internal cavity of the exterior housing opens to the environmental space 15 at the opening 55. In this modification, the opening (first opening) 55 in the ventilation assembly also opens toward the outer periphery. In the ventilation assembly, the protrusion 32 of the frame member 22 faces the opening 55 from the outer periphery. Therefore, in a ventilation assembly in which the ventilation module is attached to the mounting fixture 2, the protrusion inner circumferential surface 37 of the protrusion 32 faces the opening 55 of the ventilation module from the outer periphery.

[0077] However, in this modification, the internal cavity of the ventilation module is open to the environmental space 15 only by opening 55, and no opening similar to opening 56 of the previous embodiment is formed in the ventilation module. Instead, in this modification, an opening that opens the internal cavity to the space behind wall portion 10 is formed in addition to opening 55.

[0078] In this modification, a fan 71 is also disposed inside a ventilation module, which is an airflow generating module. When the ventilation module is installed on the wall 10 and the fan 71 is operated, air is introduced from the environmental space 15 into the interior of the ventilation module through the opening 55. Then, air is discharged from the internal cavity of the ventilation module through an opening separate from the opening 55 into the space behind the wall 10.

[0079] In this modification, when the fan 71 is operating, air flows through the opening 55. At this time, inside the ventilation module (inside the exterior housing 40), air flows from the opening 55 toward another opening other than the opening 55. The opening 55 then serves as an inlet (air intake) that introduces air into the interior of the exterior housing 40. In this modification, when the fan 71 is operated, air flows through the opening 55 as described above, generating an airflow in the environmental space 15.

[0080] In this modification as well, the ventilation module can be easily attached to the mounting fixture 2 while being surrounded by the protrusions 32 of the frame member 22. This makes it possible to easily install the ventilation module, which is an airflow generating module, on the wall 10. Also in this modification as well, the protrusion inner circumferential surface 37 of the protrusion 32 of the frame member 22 is formed with a gradient such that the closer to the protruding end of the protrusion 32 the more it is positioned on the outer circumferential side. This improves the aesthetic appearance, etc., of the ventilation assembly, which is an airflow generating assembly, when viewed visually, as in the above-described embodiment, etc.

[0081] In this modification, the opening 55 serving as the inlet opens toward the outer periphery, and when the ventilation module is attached to the frame member 22, the inner peripheral surface 37 of the protrusion 32 of the frame member 22 faces the opening 55 from the outer periphery. Therefore, in the environmental space 15, the inner peripheral surface 37 of the protrusion 32 makes it difficult for air to flow along the wall surface 11 toward the opening 55, and facilitates airflow from areas away from the wall 10 toward the opening 55. This facilitates airflow toward the ventilation module from areas away from the wall 10 in the environmental space 15, and also facilitates air introduction into the ventilation module from areas away from the wall 10. For example, when a ventilation module is installed on the ceiling wall of the environmental space 15, air is easily introduced into the ventilation module from areas away from the ceiling wall that serves as the wall 10, i.e., areas close to the floor. This improves the ventilation performance of the environmental space 15.

[0082] According to at least one of these embodiments, the mounting plate is disposed on the rear surface of the wall portion, and the frame member is attached to the mounting plate while being disposed on the front surface of the wall portion. The protrusions of the frame member protrude from the bottom plate portion toward the front side along the entire circumferential direction, and the inner peripheral surfaces of the protrusions are formed with a slope that positions closer to the protruding ends and closer to the outer periphery. This makes it possible to provide a mounting fixture that enables the airflow generation module to be easily installed on the wall of an environmental space, and an airflow generating device equipped with the mounting fixture.

[0083] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the scope of the invention and its equivalents as defined in the claims.
