An embodiment will be described below with reference to the drawings.

The air treatment device in the following embodiment is a device that performs one of the following processes on the air circulating inside the air treatment device: sterilization, disinfection, sterilization, deodorization, or deodorization using a specified method. In the following, the process of the air treatment device will be described as sterilization, but sterilization can be interpreted as sterilization, sterilization, deodorization, deodorization, etc. The specified method here is light irradiation, photocatalysis, etc. Light irradiation refers to irradiation with light of wavelengths such as the UV-C region, UV-B region, UV-A region, visible light region, and infrared region. Photocatalysis refers to suppressing the activity of bacteria, viruses, and odor sources floating in the air, or decomposing them into water and carbon dioxide, using active enzymes and OH radicals generated by irradiating light (ultraviolet light or visible light) to a photocatalyst such as titanium oxide arranged inside the air treatment device.

Air treatment system 10 is shown in Figures 1 and 2. Air treatment system 10 includes air treatment device 11 and mounting device 12 for mounting air treatment device 11 to wall surface w (see Figures 5 and 7). Note that the following explanation of the directions of air treatment device 11 and mounting device 12 refers to the directions based on the mounting posture for mounting to wall surface w. For example, the direction from wall surface w toward air treatment device 11 is the forward direction, and the direction from air treatment device 11 toward wall surface w is the rearward direction (rearward direction).

First, we will explain the mounting device 12.

As shown in Figures 1 to 3, the mounting device 12 includes a mounting member 15 whose rear side is attached to a wall surface w, and a terminal block 16 and a stay 17 attached to the front side of the mounting member 15.

The mounting member 15 is formed of a metal plate. The mounting member 15 includes a rectangular mounting plate portion 20 that is longer in the left-right direction than in the up-down direction, a first mounting portion 21 that is an upper plate portion bent from the upper side of the mounting plate portion 20 to the front side, a second mounting portion 22 that is a lower plate portion bent from the lower side of the mounting plate portion 20 to the front side, and a side plate portion 23 that is bent from the left and right sides to the front side. The first mounting portion 21, the second mounting portion 22, and the left and right side plate portions 23 are formed as a mounting frame portion 24 that is approximately rectangular in shape and has the same amount of forward protrusion from the mounting plate portion 20, and the rear side of the air treatment device 11 is disposed in front of the mounting frame portion 24. A space 25 is formed inside the mounting frame portion 24 on the front side of the mounting plate portion 20 to accommodate the terminal block 16, the stay 17, wiring, etc.

A wiring hole 26 is provided in the approximate center of the mounting plate 20 to pull the power line from the back side of the mounting plate 20 into the space 25 when wiring the power line pulled out from the wall surface w. In addition, wiring holes 27 are provided between the upper ends of the left and right side plate portions 23 and the first mounting portion 21 to pull the power line from either the left or right side of the mounting member 15 into the space 25 when wiring the power line pulled out from the wall surface w. In addition, the left and right side plate portions 23 are provided with wiring holes 28 to insert a cord with a plug to be connected to a power outlet into either the left or right side of the mounting member 15 when wiring the cord.

The first mounting portion 21 is provided with a plurality of holes (hanging holes) 29. The holes 29 are provided in three locations on the first mounting portion 21: in the center in the left-right direction and near both the left and right sides, and are formed as elongated holes that are long in the left-right direction.

The upper ends of the left and right side plate portions 23 are provided with mounting holes 30 for screw fastening. The mounting device 12 is, for example, screwed to the wall surface w through the mounting holes 30.

The first mounting portion 21 and the second mounting portion 22 may be provided integrally. For example, the first mounting portion 21 and the second mounting portion 22 may be configured as separate parts each formed into a roughly L-shape. The first mounting portion 21 and the second mounting portion 22 may also be protrusions such as structures protruding from the wall surface w.

The terminal block 16 is attached to the central area of the mounting plate portion 20 by a terminal block mounting bracket 32.

The stay 17 is rotatably attached at its lower end to the stay mounting bracket 34, and is attached to the lower side of the mounting plate 20 by the stay mounting bracket 34. The stay 17 is rotatable between a stored position in which it is arranged along the front side of the mounting plate 20 relative to the stay mounting bracket 34, and a protruding position in which it protrudes at an angle forward of the mounting plate 20. The protruding position of the stay 17 is provided with a stopper structure between it and the stay mounting bracket 34 so that rotation is restricted at a predetermined angle of inclination.

Next, we will explain the air treatment device 11.

As shown in Figures 1, 2 and 4, the air treatment device 11 includes a housing 40. Inside the housing 40, a treatment space 41 is formed in which air flows and the flowing air is irradiated with ultraviolet light. The treatment space 41 is cylindrical, and may be a rectangular parallelepiped, cube, cylinder, or other shape. The direction in which air flows in the treatment space 41 is from the right to the left in Figures 1 and 2, and from the left to the right in Figure 4. The air flow direction may be the opposite direction to that shown in Figures 1, 2 and 4.

The housing 40 is provided with a first surface 43 at one end side (upstream side in the air flow direction) in the direction in which the air of the processing space 41 flows, and has an intake port 42 which is a first ventilation hole; a second surface 45 at the other end side (downstream side in the air flow direction) in the direction in which the air of the processing space 41 flows, and has an exhaust port 44 which is a second ventilation hole and faces the first surface 43; and a third surface 46 on the front side and an attachment surface 47 on the rear side, which are surfaces in a direction intersecting the first surface 43 and the second surface 45 and are provided approximately perpendicular to the first surface 43 and the second surface 45.

The aforementioned processing space 41 includes a processing section through which air flows and is irradiated with ultraviolet light, a first processing space opening on the first ventilation port (intake port 42) side, and a second processing space opening on the second ventilation port (exhaust port 44) side. Air is drawn into the processing section from the first processing space opening, and air is exhausted to the outside of the processing section from the second processing space opening. It is preferable that the first processing space opening and the second processing space opening are configured to be approximately parallel.

The housing 40 is thin in the front-rear direction where the third surface 46 and the mounting surface 47 face each other, and the length in the direction in which the first surface 43 and the second surface 45 face each other, which is the direction in which air flows, is longer than the direction in which the surfaces arranged above and below face each other when mounted on the wall surface w, approximately perpendicular to each surface 43, 44, 46, 47.

The housing 40 includes a main body 50, and a panel 51, which is a front panel or decorative panel, is removably attached to the third surface 46, which is the front side of the main body 50. As shown in FIG. 8, a plurality of snap-catch engaging portions 52 are arranged on the two upper and lower sides of the panel 51, and as shown in FIG. 9, a plurality of snap-catch engaging portions 53 are arranged on the two upper and lower sides of the third surface 46 of the main body 50, and the panel 51 is removably attached to the third surface 46 of the main body 50 by the plurality of snap catches.

As shown in FIG. 2, the processing space 41 is formed in a cylindrical shape within the main body 50, with the front, rear, top and bottom periphery covered by a reflector 54, except for the direction of the first surface 43 communicating with the intake port 42 and the second surface 45 communicating with the exhaust port 44. The reflector 54 specularly reflects or diffuses light in the ultraviolet region.

A first ventilation cover 55 and a second ventilation cover 56 that allow air to pass through are arranged on the intake port 42 and the exhaust port 44, respectively.

On the second surface 45, in front of the exhaust port 44, there is provided an operation panel section 57 having an operation section for operating the air treatment device 11 and a display section for displaying the operating status, etc.

In addition, inside the main body 50, a first light-shielding section 60 is provided to allow air to circulate between the processing space 41 and the intake port 42 and to prevent ultraviolet light from leaking from the intake port 42 to the outside, and a second light-shielding section 61 is provided to allow air to circulate between the processing space 41 and the exhaust port 44 and to prevent ultraviolet light from leaking from the exhaust port 44 to the outside.

A fan 62 is disposed between the processing space 41 and the exhaust port 44, between the second light shielding portion 61 and the exhaust port 44, to draw in outside air through the intake port 42 and exhaust it through the exhaust port 44, thereby circulating the air through the processing space 41.

A filter storage section 63 is provided closer to the processing space 41 than the first light shielding section 60, and a filter (filter unit) 64 is removably arranged in this filter storage section 63. Also, a light irradiation section 65 that irradiates light in the ultraviolet region toward the processing space 41 is arranged closer to the processing space 41 than the second light shielding section 61. In other words, the filter 64 is arranged to face the first processing space opening on the first ventilation port (intake port 42) side of the processing space 41, and the light irradiation section 65 is arranged to face the second processing space opening on the second ventilation port (exhaust port 44) side of the processing space 41.

The filter 64 is made of, for example, wire mesh, cloth, or paper, and includes a prefilter 66 that captures foreign matter and dust sucked in with the air from the intake port 42, a photocatalyst filter 67 made of a porous base material carrying a photocatalyst such as titanium oxide, and a filter frame 68 in which the prefilter 66 and the photocatalyst filter 67 are arranged. Each of the filters 64 has a treatment surface, and is disposed so that the treatment surface faces the first treatment space opening on the first ventilation port (intake port 42) side, and the treatment surface captures foreign matter and dust, or the treatment surface carries a photocatalyst. The photocatalytic filter 67 is held and applied to a carrier with multiple ventilation holes, and when it receives ultraviolet light or visible light with a wavelength component of at least 360 nm to 420 nm of UV-A from the light irradiation unit 65 or a light irradiation unit other than the light irradiation unit 65, it generates active enzymes and OH radicals, which decompose odors and eliminate odors, or suppress viral activity. The prefilter 66 may be located closer to the intake port 42 than the first light shielding unit 60.

The light irradiation unit 65 may be an ultraviolet light source module in which multiple ultraviolet light emitting elements are mounted on the surface of a substrate. The ultraviolet light emitting elements may be an ultraviolet LED that emits ultraviolet light with a UV-C wavelength component with a peak wavelength of 300 nm or less for sterilizing air, preferably an ultraviolet LED that emits ultraviolet light with a wavelength component of 260 to 280 nm, and an ultraviolet LED that emits ultraviolet light with a UV-A wavelength component of at least 360 nm to 420 nm for exciting the photocatalyst supported on the photocatalyst filter 67. The light irradiation unit 65 is not limited to ultraviolet light emitting elements, and may be an ultraviolet light source such as an ultraviolet lamp.

As shown in FIG. 9, which shows the main body 50 with the panel 51 removed, an opening/closing door 70 that holds the filter 64 in place in the filter storage section 63 is arranged so as to be openable and closable on the third surface 46, which is the front side of the main body 50. The opening/closing door 70 is attached to the third surface 46 by a hinge 71 provided on the first surface 43 side of the main body 50 so as to be openable and closable.

10 and 11 show the state in which the reflector 54 on the front side of the processing space 41 from FIG. 9 is omitted and the opening and closing door 70 is opened. By opening the opening and closing door 70, the front side of the filter storage section 63 is opened between the reflector 54 on the front side and the first light shielding section 60, and the filter 64 can be pulled out and removed in a direction substantially perpendicular to the third surface 46 of the main body 50 (housing 40), or inserted from the front substantially perpendicular to the third surface 46 and attached. A pressure spring 72 is attached to the third surface 46 of the main body 50 to elastically engage with and hold the filter 64 inserted in the filter storage section 63.

A pair of wire attachment parts 74, which are housing side wire attachment parts, are provided on the two upper and lower sides of the periphery of the third surface 46 of the main body 50. One end of a wire 75 is attached to one of the upper and lower wire attachment parts 74 by a mounting structure such as a screw fastening or a hook-and-lock structure. The other end of the wire 75 is attached to the rear side of the panel 51. As shown in FIG. 8, a pair of wire attachment parts 76, which are panel side wire attachment parts, are provided on the two upper and lower sides of the periphery of the rear side of the panel 51. The other end of the wire 75 is attached to one of the upper and lower wire attachment parts 76 by a mounting structure such as a screw fastening or a hook-and-lock structure. For example, in the position of the air treatment device 11 attached to the wall surface w, the wire 75 is attached between the wire attachment part 74 on the lower side of the main body 50 and the wire attachment part 76 on the lower side of the panel 51, and when the panel 51 is removed, the wire 75 supports the panel 51 by hanging it.

In addition, inside the frame between the outer surface of the main body 50 and the treatment space 41, a fan drive unit that drives the fan 62, a lighting unit that turns on the light irradiation unit 65, a control unit that controls the air treatment device 11, etc. are arranged.

Also, as shown in FIG. 4, a wiring pull-out section 78 is provided at one corner of the mounting surface 47 of the housing 40, through which wiring for inputting external power is pulled out.

In addition, a hook member 80 and a support member 81 are attached to the mounting surface 47 of the housing 40 for mounting to the mounting member 15 of the mounting device 12 attached to the wall surface w. The hook member 80 is attached along the upper edge of the mounting surface 47 of the housing 40, and the support member 81 is attached along the lower edge of the mounting surface 47 of the housing 40.

The hook member 80 is a long metal plate formed with a generally L-shaped cross section. The hook member 80 has a housing attachment part 83 that is attached to the mounting surface 47 of the housing 40, and a first protrusion 84 that is bent from the upper side of the housing attachment part 83.

At both ends of the longitudinal direction of the housing mounting portion 83, the side portions 85 on both sides are bent so as to protrude from the mounting surface 47, be approximately parallel to the first surface 43 and the second surface 45 of the housing 40, and be approximately perpendicular to the mounting surface 47. The distance between the side portions 85 on both sides is wider than the distance between the outer surfaces of the side plate portions 23 on both sides of the mounting member 15, and the side portions 85 on both sides can be arranged outside the side plate portions 23 on both sides. The side portions 85 on both sides are provided with screw insertion holes 86 for inserting screws to screw into the mounting holes 30 of the side plate portions 23 on both sides of the mounting member 15. At one end of the longitudinal direction of the housing mounting portion 83, a notch portion 87 is provided that is cut out across the first protrusion 84.

The first protrusion 84 protrudes from the mounting surface 47 of the housing 40 and is provided on the mounting surface 47 in a direction toward the outside of the housing 40 so as to be approximately perpendicular to the first surface 43, the second surface 45, and the mounting surface 47 of the housing 40. The tip side of the first protrusion 84 is provided with a plurality of hooks 88 that are inserted into holes 29 provided in the first mounting portion 21 of the mounting member 15. The hooks 88 are provided in three locations, at the center in the left-right direction of the first protrusion 84 and near both left and right sides, and are formed in the shape of a tongue that is long in the left-right direction.

The support member 81 is a long metal plate formed with a generally L-shaped cross section. The support member 81 includes a housing attachment portion 90 that is attached to the mounting surface 47 of the housing 40, and a second protrusion 91 that is bent from the lower side of the housing attachment portion 90.

The second protrusion 91 protrudes from the mounting surface 47 of the housing 40 and is provided on the mounting surface 47 in a direction toward the outside of the housing 40 and below the first protrusion 84 so as to be approximately perpendicular to the first surface 43, the second surface 45, and the mounting surface 47.

The housing 40 is then installed on the mounting member 15 such that the first protrusion 84 is positioned above the first mounting portion 21 of the mounting member 15 provided on the wall surface w, the second protrusion 91 is positioned above the second mounting portion 22, and the hook portion 88 of the first protrusion 84 is inserted into the hole 29 of the first mounting portion 21.

As shown in FIG. 6, the housing 40 can also be installed in an orientation in which the intake port 42 and the exhaust port 44 face in the opposite direction to that shown in FIG. 1 and FIG. 4. In this case, the hook member 80 is attached to the housing 40 with the intake port 42 and the exhaust port 44 facing in the opposite direction along the upper edge of the mounting surface 47 of the housing 40, and the support member 81 is attached to the lower edge of the mounting surface 47 of the housing 40. At this time, the hook member 80 is configured so that the cutout portion 87 faces the wiring pull-out portion 78 of the housing and does not interfere with the wiring pulled out from the wiring pull-out portion 78.

Next, we will explain the installation of the air treatment system 10.

The rear side of the mounting member 15 of the mounting device 12 is placed on the wall w and fixed to the wall w with screws. At this time, if a power line is pulled out from the wall w, the power line is pulled in through either the wiring hole 26 of the mounting member 15 or one of the wiring holes 27 on both sides depending on the position where the power line is pulled out, and electrically connected to the terminal block 16. If a cord with a plug is used, the cord is passed through either one of the wiring holes 30 on both sides depending on the position of the outlet to which the plug is connected, and electrically connected to the terminal block 16.

The air treatment device 11 is lifted up, and each hook portion 88 of the first protrusion 84 protruding from the mounting surface 47 of the housing 40 is inserted from above into each hole 29 of the first mounting portion 21 of the mounting member 15, and the first protrusion 84 is placed so as to be hooked onto the upper side of the first mounting portion 21. By inserting each hook portion 88 of the first protrusion 84 into each hole 29 of the first mounting portion 21, the left-right positions of the mounting member 15 and the housing 40 are determined, and the side portions 85 on both sides of the hook member 80 are positioned outside the side plate portions 23 on both sides of the mounting member 15.

As shown in FIG. 7, the stay 17 is rotated to a forward protruding position, and the lower side of the mounting surface 47 of the housing 40 is abutted against the tip of the stay 17, so that the housing 40 is temporarily supported in an inclined position with a gap between it and the lower side of the mounting member 15. In this state, the wiring drawn out from the wiring draw-out portion 78 of the housing 40 can be easily electrically connected to the terminal block 16.

After the wiring is completed, the stay 17 is rotated to a storage position in which it is stored in the space 25 of the mounting member 15, and the lower side of the housing 40 is rotated toward the mounting member 15, with the point where the first protrusion 84 is hooked onto the first mounting portion 21 as a fulcrum. This rotation with the upper side of the housing 40 as a fulcrum moves the second protrusion 91 to the upper side of the second mounting portion 22, as shown in FIG. 5, and the second protrusion 91 rests on and is supported by the upper side of the second mounting portion 22.

The side surface portions 85 on both sides of the hook member 80 are disposed on the outside of the side plate portions 23 on both sides of the mounting member 15, and screws passing through the screw insertion holes 86 of the side surface portions 85 on both sides are screwed into the mounting holes 30 of the side plate portions 23 on both sides to fix the hook member 80 to the mounting member 15. As a result, the hook portions 88 of the first protrusion 84 are inserted into the holes 29 of the first mounting portion 21 and fixed in a hooked state.

When the housing 40 is attached to the mounting member 15, the terminal block 16, the stays 17, wiring, etc. are housed in the space 25 within the mounting member 15, which is the space between the mounting surface 47 of the housing 40 and the wall surface w.

In addition, the air treatment device 11 can be installed in any orientation, with the intake port 42 and exhaust port 44 of the housing 40 facing in the opposite directions, as shown in Figures 4 and 6.

In this case, one end of the wire 75 is attached to the panel 51, and the other end is attached to the wire attachment portion 74 of the housing 40. Since a pair of wire attachment portions 74 are provided on two opposing sides of the periphery of the third surface 46 of the housing 40, the wire 75 is attached to whichever wire attachment portion 74 it is attached to depending on the installation orientation of the housing 40. For example, the other end of the wire 75 is attached to the wire attachment portion 74 located on the lower side depending on the installation orientation of the housing 40. Also, since a pair of wire attachment portions 76 are provided on two opposing sides of the panel 51, the wire 75 is attached to whichever wire attachment portion 74 it is attached to depending on the orientation of the panel 51, which corresponds to the installation orientation of the housing 40. For example, one end of the wire 75 is attached to the wire attachment portion 76 located on the lower side depending on the installation orientation of the panel 51.

When external power is supplied to the air treatment device 11, the fan 62 rotates, and external air is drawn in through the intake port 42 and exhausted through the exhaust port 44, circulating through the treatment space 41. The air drawn in through the intake port 42 is circulated through the first light shielding section 60 and the pre-filter 66 and photocatalytic filter 67 of the filter 64 into the treatment space 41. The air in the treatment space 41 is exhausted to the outside through the exhaust port 44 via the second light shielding section 61 and the fan 62.

The pre-filter 66 captures foreign objects and dust that are sucked in along with the air through the intake port 42.

When the photocatalyst filter 67 is exposed to ultraviolet or visible light, it generates active enzymes and OH radicals, which decompose and eliminate odors and suppress viral activity.

The air flowing through the treatment space 41 is irradiated with ultraviolet light from the light irradiation unit 65, and the air sterilized by the ultraviolet light is discharged to the outside through the exhaust port 44.

Each light-shielding portion 60, 61 prevents ultraviolet light irradiated into the processing space 41 from leaking to the outside through the intake port 42 and exhaust port 44.

The filter 64, which includes the pre-filter 66 and the photocatalytic filter 67, can be removed from the housing 40 for cleaning or replacement. First, as shown in FIG. 9, the panel 51 is removed from the main body 50 to expose the third surface 46 of the main body 50. Next, as shown in FIG. 10, the opening and closing door 70 is opened, and then, as shown in FIG. 11, the filter 64 is pulled forward from the third surface 46 of the main body 50 for cleaning or replacement.

As shown in FIG. 10, insert the cleaned or replaced filter 64 into the filter storage section 63 from the front through the third surface 46 of the main body 50, then close the opening and closing door 70 as shown in FIG. 9, and then attach the panel 51 to the main body 50.

In addition, since the panel 51 removed from the main body 50 is connected to the main body 50 by the wire 75, the removed panel 51 is supported in a state in which it is suspended from the main body 50 by the wire 75 without being placed on the floor or the like. This makes it easy to perform maintenance work on the filter 64.

In the embodiment of the air treatment system 10 and air treatment device 11, the housing 40 is installed so that the first protrusion 84 is positioned above the first mounting portion 21 of the mounting member 15 provided on the wall surface w, and the second protrusion 91 is positioned above the second mounting portion 22, so that it can be stably attached to the wall surface w.

Furthermore, the hook portion 88 of the first protrusion 84 is inserted into the hole 29 of the first mounting portion 21, thereby preventing the first protrusion 84 from coming off the first mounting portion 21.

Furthermore, since the housing 40 is installed so that there is a space between the mounting surface 47 and the wall surface w, wiring components, mounting components, wiring, etc. can be accommodated in the space, improving the design.

In addition, since the filter 64 can be pulled out from the third surface 46, which is the front side of the housing 40, the filter 64 can be removed even if the rear side of the air treatment device 11 is installed on a wall surface w. This eliminates the need to restrict the installation of the air treatment device 11 in order to remove the filter 64, and does not require moving the air treatment device 11 in order to remove the filter 64, making it possible to provide an air treatment device 11 that is highly versatile in its installation.

Furthermore, a pair of wire attachment parts 74 are provided on two opposing sides of the periphery of the third surface 46 of the main body 50, and one end of a wire 75 is attached to the panel 51, and the other end of the wire 75 can be attached to any one of the wire attachment parts 74 depending on the installation orientation of the housing 40, so that the installation orientation of the housing 40 can also be changed.

As shown in FIG. 12, the air treatment device 11 can also be used as a floor-standing type, placed on the floor. In this case, a stand 95 is used to support the lower side of the vertical housing 40, with the intake port 42 facing downward and the exhaust port 44 facing upward, against the floor. In the case of a floor-standing type, the wall-hanging hook member 80 and support member 81, and the first ventilation cover 55 of the intake port 42 are not used. As shown in FIG. 13, floor-standing brackets 96 protruding from the stand 95 are fixed by screws to both sides of the metal internal structure of the main body 50 with the side covers removed.

The air treatment device 11 can be used as either a wall-mounted or floor-standing type, and many of the parts can be standardized.

The wall-mounted air treatment device 11 and the floor-standing air treatment device 11 may be constructed separately, or the installation location of the air treatment device 11 may be changed between wall-mounted and floor-standing. When the air treatment device 11 is to be changed between wall-mounted and floor-standing, the portion of the lower part of the housing 40 where the floor-standing bracket 96 is attached may be partially configured to be easily opened, closed, or removed so that the floor-standing bracket 96 can be easily attached or removed.
