DETAILED DESCRIPTION OF THE INVENTION

[0009] The mounting device (2) of this embodiment includes a module mounting portion (13), an extension portion (10), an object connection portion (60), a first contact portion (65), and a second contact portion (66). The air treatment module (3) is mounted to the module mounting portion (13), and the extension portion (10) extends downward in the height direction from the module mounting portion (13). The object connection portion (60) is provided on the extension portion (10), and an odor-generating object (5) is connected to the object connection portion (60) from one side in the depth direction that intersects with the height direction. The first contact portion (65) contacts the object (5) connected to the object connection portion (60) at a position away from the object connection portion (60) on one side of the extension portion (10) in the width direction that intersects with both the height direction and the depth direction. The second contact portion (66) contacts the object (5) connected to the object connection portion (60) at a position on the extension portion (10) opposite the side where the first contact portion (65) is located in the width direction and away from the object connection portion (60). This allows the object (5) to be placed in the mounting fixture (2) to which the air treatment module (3) is attached, and the air treatment module (3) attached to the mounting fixture (2) to efficiently deodorize the odor from the object (5). This effectively prevents the object (5) from being accidentally removed from the mounting fixture (2) by external force from the user of the object (5), such as a pet.

[0010] The mounting fixture (2) of this embodiment further includes a freestanding installation section (45) that installs the extension section (10) in a freestanding state on the installation surface (6), thereby effectively preventing the mounting fixture (2) installed on the installation surface (6) and the air treatment module (3) attached to the mounting fixture (2) from tipping over.

[0011] In the mounting device (2) of this embodiment, the free-standing installation section (45) includes an installation plate section (45) that is placed on the installation surface (6) adjacent to the lower side in the height direction of the object (5) connected to the object connection section (60). This eliminates the need to secure a space for placing the installation plate section (45) on the installation surface (6) separate from the space for placing the object (5), and makes it possible to reduce the area of ​​the portion of the installation surface (6) where the object (5) and the air treatment device (1) are placed.

[0012] The mounting device (2) of this embodiment further includes a sensor installation section (71) provided in the extension section (10) between the module installation section (13) and the object connection section (60), and a sensor (72) is installed in the sensor installation section (71). This allows the sensor (72) to appropriately detect either an odor generated in the object (5) or the condition of the object (5).

[0013] The air treatment device (1) of this embodiment includes an air treatment module (3), an extension portion (10), an object connection portion (60), a first contact portion (65), and a second contact portion (66). The air treatment module (3) operates to perform air treatment. The air treatment module (3) is attached to the extension portion (10), and the extension portion (10) extends downward in the height direction from the air treatment module (3). The object connection portion (60) is provided on the extension portion (10), and an object (5) that is an odor source is connected to the object connection portion (60) from one side in the depth direction that intersects with the height direction. The first contact portion (65) contacts the object (5) connected to the object connection portion (60) at a position away from the object connection portion (60) on one side of the extension portion (10) in the width direction that intersects with both the height direction and the depth direction. The second contact portion (66) contacts the object (5) connected to the object connection portion (60) at a position on the extension portion (10) opposite the side where the first contact portion (65) is located in the width direction and away from the object connection portion (60). This allows the object (5) to be placed in the mounting fixture (2) to which the air treatment module (3) is attached, and the air treatment module (3) attached to the mounting fixture (2) to efficiently deodorize the odor from the object (5). This effectively prevents the object (5) from being accidentally removed from the mounting fixture (2) by external force from the user of the object (5), such as a pet.

[0014] The air treatment device (1) of this embodiment further includes a sensor (72) and a connection cable (73), and the sensor (72) is installed in the extension portion (10) between the air treatment module (3) and the object connection portion (60). The connection cable (73) extends from the sensor (72) to the air treatment module (3) along the extension portion (10) and connects the air treatment module (3) to the sensor (72). Thus, even in a configuration in which the sensor (72) is externally attached to the air treatment module (3), a signal indicating the detection result of the sensor (72) can be appropriately transmitted to the control unit of the air treatment module (3) via the connection cable (73).

[0015] Hereinafter, embodiments will be described with reference to the drawings.

[0016] Fig. 1 is a perspective view showing an air treatment device 1 according to an embodiment and an example of a usage mode of the air treatment device 1. As shown in Fig. 1, the air treatment device 1 includes an attachment device 2 and an air treatment module 3. In this embodiment, a pet litter box 5 is detachably installed in the attachment device 2 as an object that is a source of odor.

[0017] The air treatment device 1 and the mounting fixture 2 are defined as having a height direction (the direction indicated by arrows H1 and H2), a depth direction (the direction indicated by arrows D1 and D2) that intersects (is perpendicular or nearly perpendicular to) the height direction, and a width direction (the direction indicated by arrows W1 and W2) that intersects (is perpendicular or nearly perpendicular to) both the height direction and the depth direction. Furthermore, the air treatment device 1 and the mounting fixture 2 have one side in the height direction as the upper side (the arrow H1 side), and the opposite side of the upper side in the height direction as the lower side (the arrow H2 side). Furthermore, the air treatment device 1 and the mounting fixture 2 have one side in the depth direction as the front side (the arrow D1 side), and the opposite side of the front side in the depth direction as the rear side (the arrow D2 side).

[0018] The mounting fixture 2 is installed in a freestanding state on an installation surface 6 such as a floor in an environmental space such as a room. The mounting fixture 2 is installed on the installation surface 6 with its upper side in the height direction aligned or approximately aligned with the vertically upper side, and is installed freestanding on the installation surface 6 with its extending vertically upward from the installation surface 6. In the example of FIG. 1 , a side wall surface 7 of the environmental space such as a room is adjacent to the mounting fixture 2 from the rear side. Note that the mounting fixture 2 may also be installed freestanding on the installation surface 6 at a position away from the side wall surface 7.

[0019] The pet toilet 5, which is the target object, is detachable from the mounting fixture 2 and is removably installed in the mounting fixture 2. Therefore, the pet toilet 5 can be separated from the mounting fixture 2. Figure 2 shows the air treatment device 1 and the pet toilet 5 according to the embodiment in a state where the pet toilet 5 is separated from the mounting fixture 2.

[0020] As shown in Figures 1 and 2, the mounting fixture 2 has an extension portion (extension frame portion) 10 that extends along the height direction. In the example shown in Figures 1 and 2, the extension portion 10 has an upper frame 11 and a lower frame 12. In the extension portion 10, the lower frame 12 is connected to the upper frame 11 from below in the height direction. Connection holes 15 and 16 are formed in the upper frame 11. Connection hole 15 is located above connection hole 16 in the height direction of the mounting fixture 2. The upper frame 11 is connected to the lower frame 12 through one of connection holes 15 and 16.

[0021] When the upper frame 11 is connected to the lower frame 12 via the connection holes 16, the dimension of the extension portion 10 along the height direction is larger than when the upper frame 11 is connected to the lower frame 12 via the connection holes 15. Therefore, the dimension of the extension portion 10 along the height direction can be adjusted by adjusting the connection position of the upper frame 11 to the lower frame 12. In other words, the dimension of the extension portion 10 along the height direction of the mounting fixture 2 is variable. Note that Figures 1 and 2 show the state in which the upper frame 11 is connected to the lower frame 12 via the connection holes 15.

[0022] The extension section 10 has a module mounting section 13 provided at its upper end in the height direction, i.e., at its upper end. Therefore, in the mounting device 2, the extension section 10 extends downward in the height direction from the module mounting section 13. In the mounting device 2 that is self-standing on the installation surface 6, the extension section 10 extends vertically downward from the module mounting section 13, and extends from the module mounting section 13 toward the installation surface 6. In the mounting device 2, the air treatment module 3 is mounted to the module mounting section 13. The air treatment module 3 is mounted to the module mounting section 13 from above in the height direction.

[0023] 3 to 5 show an example of the configuration of the air treatment module 3 and the module mounting portion 13 of the mounting fixture 2 in the air treatment device 1 according to this embodiment. Fig. 3 shows a perspective view, and Figs. 4 and 5 show perspective views of a state cut along a cross section perpendicular or substantially perpendicular to the width direction. The cross section in Fig. 5 is different from that in Fig. 4. As shown in Figs. 1 to 5, etc., the air treatment module 3 has an exterior housing 20 that forms the exterior, and in the air treatment module 3, an internal cavity is formed inside the exterior housing 20.

[0024] The air treatment module 3 and the exterior housing 20 have defined height directions, depth directions that intersect with the height directions (perpendicular or approximately perpendicular), and width directions that intersect with both the height and depth directions (perpendicular or approximately perpendicular). Furthermore, for the air treatment module 3 and the exterior housing 20, 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. Furthermore, for the air treatment module 3 and the exterior housing 20, one side in the depth direction is the front side, and the side opposite the front side in the depth direction is the rear side. In the air treatment device 1, the air treatment module 3 is attached to the module attachment portion 13 of the attachment fixture 2 such that the upper side of the air treatment module 3 in the height direction coincides or approximately coincides with the upper side of the attachment fixture 2 in the height direction, and the front side of the air treatment module 3 coincides or approximately coincides with the front side of the attachment fixture 2.

[0025] The exterior housing 20 of the air treatment module 3 includes a bottom plate portion 21, a top plate portion 22, and a peripheral plate portion 23. In the air treatment module 3, the bottom plate portion 21 covers the internal cavity from below in the height direction, and the top plate portion 22 covers the internal cavity from above in the height direction. The top plate portion 22 faces the bottom plate portion 21 with the internal cavity of the exterior housing 20 sandwiched therebetween. The peripheral plate portion 23 extends in the height direction from the bottom plate portion 21 to the top plate portion 22. The peripheral plate portion 23 covers the internal cavity from the outer periphery, covering the internal cavity over the entire circumferential direction.

[0026] The peripheral plate portion 23 includes a front plate portion 25 that covers the internal cavity from the front side in the depth direction, and a rear plate portion 26 that covers the internal cavity from the rear side in the depth direction. The rear plate portion 26 faces the front plate portion 25, with the internal cavity of the exterior housing 20 sandwiched therebetween. In addition, openings 27 and 28 to the outside are formed in the exterior housing 20. The opening (first opening) 27 is formed in the bottom plate portion 21 and opens downward in the height direction. In addition, the opening (second opening) 28 is formed in the top plate portion 22 and opens upward in the height direction.

[0027] In the examples shown in FIGS. 4 and 5 , a processing box 30 is disposed inside the exterior housing 20. A space 31 is formed inside the processing box 30. Furthermore, inside the exterior housing 20, a space 32 is formed between the bottom plate portion 21 and the processing box 30 in the height direction, and a space 33 is formed between the top plate portion 22 and the processing box 30 in the height direction. Furthermore, inside the exterior housing 20, a space 35 is formed between the rear plate portion 26 and the processing box 30 in the depth direction. Inside the exterior housing 20, the space 32 opens to the outside of the exterior housing 20 through an opening 27, and the space 33 opens to the outside of the exterior housing 20 through an opening 28. Furthermore, inside the exterior housing 20, the opening 27 communicates with the opening 28 only through the spaces 32, 35, 31, and 33, in this order.

[0028] A fan 36 is disposed in the space 31 inside the exterior housing 20 (inside the air treatment module 3). In one example shown in FIGS. 4 and 5 , the fan 36 is a sirocco fan. In the air treatment module 3, the fan 36 is operated by the supply of power, and air is introduced into the space 32 inside the exterior housing 20 through the opening 27. At this time, air is introduced into the interior of the exterior housing 20 from the lower side in the height direction. Then, inside the exterior housing 20, air flows through the space 32, the space 35, the space 31, and the space 33 in this order. Then, air is discharged from the space 32 inside the exterior housing 20 to the outside of the exterior housing 20 through the opening 28. At this time, air is discharged from the interior of the exterior housing 20 toward the upper side in the height direction.

[0029] When the above-described air flow is formed by the operation of the fan 36, the opening 27 serves as an inlet (air intake) for introducing air into the interior of the exterior housing 20, and the opening 28 serves as an outlet for discharging air from the interior of the exterior housing 20. Note that the air flow inside the exterior housing 20 is not limited to the air flow in the example described above. In another example, the peripheral plate portion 23 has an opening 28, and the internal cavity of the exterior housing 20 opens toward the outer periphery at the opening 28. In this case, operation of the fan 36 causes air to be discharged from the interior of the exterior housing 20 toward the outer periphery through the opening 28, which serves as an outlet. However, in both examples, the opening 27, which serves as an inlet, opens downward in the height direction. Then, operation of the fan 36 causes air to be introduced into the interior of the exterior housing 20 from the lower side in the height direction through the opening 27.

[0030] Furthermore, inside the exterior housing 20, an ultraviolet light source 37 and a photocatalyst module 38 are arranged in a space 31 inside the processing box 30. In one example shown in Figures 4 and 5, etc., in the space 31, the photocatalyst module 38 is arranged at a distance from the ultraviolet light source 37 to the rear side in the depth direction. In the space 31, the ultraviolet light source 37 is arranged between the fan 36 and the photocatalyst module 38 in the depth direction.

[0031] When power is supplied, the ultraviolet light source 37 performs a light emitting operation, and thereby emits ultraviolet light. In one example shown in Figures 4 and 5, the ultraviolet light source 37 emits ultraviolet light toward the photocatalyst module 38 in the space 31 inside the treatment box 30. In one example, the ultraviolet light source 37 includes a light emitting element such as an ultraviolet LED. Note that, instead of the light emitting element, the ultraviolet light source 37 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.

[0032] In the photocatalyst module 38, a photocatalyst is supported on the surface of a base material. In the photocatalyst module 38, 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. In the photocatalyst module 38, air passes through the through-holes formed in the base material.

[0033] In the example shown in FIGS. 4 and 5 , air treatment is performed using ultraviolet light emitted from an ultraviolet light source 37 and a photocatalyst module 38. The ultraviolet light source 37 emits ultraviolet light, i.e., UV-A, with a peak wavelength in the range of 320 nm or more and 400 nm or less. At least a portion of the ultraviolet light emitted from the ultraviolet light source 37 is incident on the photocatalyst module 38 directly and / or after reflection. When the UV-A is incident on the photocatalyst module 38, active oxygen and OH radicals are generated in the photocatalyst module 38. The generated active oxygen and OH radicals then decompose odorous substances, viruses, fungi (bacteria), and the like contained in the air flowing toward the opening 28 (exhaust port). This results in deodorization, sterilization, and the like of the air inside the exterior housing 20. The air that has been subjected to air treatment, such as deodorization and sterilization, is then discharged to the outside of the exterior housing 20 through the opening 28.

[0034] In one example, the ultraviolet light source 37 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 31. In this example, the UV-C is irradiated onto the air from the ultraviolet light source 37, thereby suppressing the activity of viruses and bacteria (bacteria) contained in the air flowing through the space 31. This sterilizes the air inside the exterior housing 20.

[0035] "Deodorization" means, for example, mitigating the effects of odorous substances present in the air, and terms such as "deodorization" and "odor reduction" can be used instead of "deodorization." "Sterilization" means, for example, inactivating viruses and bacteria (bacteria) present in the air, and terms such as "sterilization," "sterilization," and "sterilization" can be used instead of "sterilization."

[0036] In one example, instead of or in addition to the air treatment using ultraviolet light or the like described above, air treatment using ozone is performed. In this case, an ozone generator is disposed inside exterior housing 20. Inside exterior housing 20, air treatment is performed by mixing ozone with air flowing from opening 27 (inlet) toward opening 28 (outlet). The air mixed with ozone is then discharged to the outside of exterior housing 20 through opening 28. In this case, the ozone discharged from inside exterior housing 20 deodorizes and sterilizes the air.

[0037] 4 etc., a relay member 41 is provided at the module mounting portion 13, which is the portion where the air treatment module 3 is mounted to the extension portion 10. At the module mounting portion 13, the upper frame 11 of the extension portion 10 is mounted to the exterior housing 20 of the air treatment module 3 via the relay member 41. The relay member 41 is attached to the bottom plate portion 21 in a state where it abuts against the outer surface of the bottom plate portion 21 of the exterior housing 20, and is attached to the bottom plate portion 21 in a state where it abuts against the bottom plate portion 21 from below in the height direction.

[0038] 4 etc., the processing box 30 disposed inside the exterior housing 20 is connected to the bottom plate portion 21 of the exterior housing 20 by screws 42 etc. The relay member 41 is connected to the bottom plate portion 21 by being fastened together with the bottom plate portion 21 and the processing box 30 by screws 42 etc. Furthermore, in the example of FIG. 4 etc., the upper frame 11 of the extension portion 10 is connected to the relay member 41 by screws 43 etc.

[0039] In one example, the exterior housing 20 is connected to the bottom plate 21 by screws other than the screws 42 used to connect the processing box 30 to the exterior housing 20. In another example, the relay member 41 is not provided on the module mounting portion 13, and the upper frame 11 of the extension portion 10 is directly attached to the bottom plate 21 of the exterior housing 20. In this case, the upper frame 11 may be connected to the bottom plate 21 by fastening the bottom plate 21 and the processing box 30 together with screws 42 or the like, or may be connected to the bottom plate 21 by screws other than the screws 42 used to connect the processing box 30 to the exterior housing 20.

[0040] 1 and 2, the mounting fixture 2 is provided with a mounting plate 45 as a free-standing mounting part. The mounting plate 45 is connected to the lower end in the height direction of the extension part 10 of the mounting fixture 2, i.e., the lower end. In the mounting fixture 2, the extension part 10 and the mounting plate 45 form legs. The mounting plate 45 extends from the connection position to the extension part 10 toward the front side in the depth direction, and protrudes forward relative to the extension part 10.

[0041] In one example shown in Figures 1 and 2, the mounting device 2 is used with the mounting plate 45 placed on a mounting surface 6 such as a floor. The mounting plate 45 defines a plate thickness direction, and the plate thickness direction of the mounting plate 45 is along the height direction of the mounting device 2. The mounting plate 45 is placed on the mounting surface 6 in a state where it abuts against the mounting surface 6 from the upper side in the height direction (vertically upper side). By placing the mounting plate 45 on the mounting surface 6 as described above, the mounting device 2 including the extension portion 10 is placed on the mounting surface 6 in a freestanding state.

[0042] In one example, the installation plate portion 45 extends rearward in the depth direction from the connection position with the extension portion 10 and protrudes rearward relative to the extension portion 10. In this case, the mounting fixture 2 is installed on the installation surface 6 at a position away from the side wall surface 7. In this example, the installation plate portion 45 is also arranged on the installation surface 6 so that the thickness direction of the installation plate portion 45 is aligned with the height direction of the mounting fixture 2 and the installation plate portion 45 abuts against the installation surface 6 from above in the height direction (vertically above). Therefore, in this example, the mounting fixture 2 including the extension portion 10 is installed on the installation surface 6 in a free-standing state. In another example, the installation plate portion 45 serving as a free-standing installation portion is not provided on the mounting fixture 2. In this case, the mounting fixture 2 including the extension portion 10 is installed on the side wall surface 7 by connecting the extension portion 10 to the side wall surface 7 using, for example, screws or the like.

[0043] 1 and 2, the extension portion 10 includes a pair of pillar portions 46, 47. Each of the pillar portions 46, 47 extends along the height direction from the upper end to the lower end of the extension portion 10. The pillar portions 46, 47 are spaced apart from each other in the width direction. Each of the pillar portions 46, 47 protrudes forward in the depth direction from the extension portion 10.

[0044] Fig. 6 shows an example of a pet toilet 5, which is an object to be installed in the attachment device 2 in the embodiment. Fig. 7 shows the state in which the pet toilet 5 is installed in the attachment device 2 in the embodiment. Fig. 6 shows a perspective view, and Fig. 7 shows a cross section perpendicular or approximately perpendicular to the height direction. As shown in Figs. 6 and 7, the pet toilet 5 includes an outer container 50.

[0045] The pet toilet 5 and the outer container 50 have defined height directions, depth directions that intersect with the height direction (perpendicular or approximately perpendicular), and width directions that intersect with both the height direction and the depth direction (perpendicular or approximately perpendicular). Furthermore, in the pet toilet 5 and the outer container 50, 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. Furthermore, in the pet toilet 5 and the outer container 50, one side in the depth direction is the front side, and the side opposite the front side in the depth direction is the rear side. The pet toilet 5 is installed in the mounting fixture 2 such that the upper side of the pet toilet 5 in the height direction coincides or approximately coincides with the upper side of the mounting fixture 2 in the height direction, and the front side of the pet toilet 5 coincides or approximately coincides with the front side of the mounting fixture 2.

[0046] The outer container 50 of the pet toilet 5 includes a bottom wall 51 and a peripheral wall 52. In the outer container 50, a sheet 53 is laid on the surface of the bottom wall 51 facing upward in the height direction. The portion of the bottom wall 51 on which the sheet 53 is laid is formed as an excretion area Q1 where the pet urinates, defecates, etc. In the outer container 50, the peripheral wall 52 is connected to the bottom wall 51 and extends upward in the height direction from the connection position to the bottom wall 51. The peripheral wall 52 covers the excretion area Q1 from the outer periphery.

[0047] An opening 55 that opens toward the front side is formed in the peripheral wall 52. In one example such as FIG. 6 , the peripheral wall 52 does not extend upward from the bottom wall 51 in the area where the opening 55 is formed. In another example, the peripheral wall 52 is formed lower in the area where the opening 55 is formed than in other parts. By forming the opening 55 as in any of the examples described above, a recessed portion that is recessed downward in the height direction is formed in the area of ​​the peripheral wall 52 where the opening 55 is formed. When the pet toilet 5 is in use, the pet enters the excretion area Q1 through the opening 55 (recessed portion) and exits the excretion area Q1 through the opening 55.

[0048] The peripheral wall 52 also includes a rear wall 56 that covers the excretion area Q1 from the rear side. In the example pet toilet 5 shown in Figures 6 and 7, a plate member 57 is attached to the outer surface of the rear wall 56. The plate member 57 is attached to the lower end of the rear wall 56 in the height direction, i.e., the bottom end, and is fixed to the rear wall 56 by at least one of screws and double-sided tape. The plate member 57 is made of a magnetic metal.

[0049] Furthermore, an object connection part 60 to which the pet toilet 5, which is the object, is connected is formed at the lower end in the height direction, i.e., the bottom end, of the extension part 10 of the attachment device 2. In the embodiment and the like, the pet toilet 5 is installed in the attachment device 2 by connecting the pet toilet 5 to the object connection part 60. In one example, such as in Figures 2 and 7, the object connection part 60 includes a magnet 61. The magnet 61 is attached to the extension part 10 with a mounting bracket 62 interposed therebetween. Furthermore, in the extension part 10 of the attachment device 2, the object connection part 60 including the magnet 61 is located between the columnar parts 46, 47 in the width direction.

[0050] When the pet toilet 5 is installed in the attachment device 2, the object connection part 60 is connected to the plate member 57 of the pet toilet 5. Therefore, the pet toilet 5 is installed in the attachment device 2 by connecting the plate member 57 to the object connection part 60 from the front side. In the example shown in Figures 2 and 7, the attractive force from the magnet 61 causes the plate member 57 to stick to the magnet 61 from the front side, and the pet toilet 5 is connected to the object connection part 60.

[0051] In one example, an appliance-side fitting portion is formed in the object connection portion 60 formed at the lower end of the extension portion 10, and an object-side fitting portion is formed in the rear wall portion 56 of the pet toilet 5. Then, the appliance-side fitting portion is fitted into the object-side fitting portion by snap fitting or the like, thereby connecting the pet toilet 5 to the object connection portion 60. In this case, too, the pet toilet 5 is installed in the mounting fixture 2 by connecting the pet toilet 5 to the object connection portion 60 from the front side.

[0052] In a preferred example, the mounting bracket 62 allows the height position of the object connection part 60 including the magnet 61 to be adjusted. The mounting bracket 62 also allows the posture of the object connection part 60 including the magnet 61 to be adjusted. In this case, the height position of the object connection part 60 can be adjusted to correspond to the position where the plate member 57 is attached in the pet toilet 5, etc. The posture of the object connection part 60 can also be adjusted to correspond to the draft angle of the part of the pet toilet 5 where the plate member 57 is attached.

[0053] Furthermore, when the pet toilet 5 is connected to the object connection part 60, i.e., when the pet toilet 5 is installed in the mounting device 2, the lower ends of the pillar parts 46, 47 come into contact with the pet toilet 5. That is, a contact part (first contact part) 65 that comes into contact with the pet toilet 5 connected to the object connection part 60 is provided at the lower end of the pillar part (first pillar part) 46, and a contact part (second contact part) 66 that comes into contact with the pet toilet 5 connected to the object connection part 60 is provided at the lower end of the pillar part (second pillar part) 47.

[0054] Each of the contact portions 65, 66 contacts the pet toilet 5, which is the object connected to the object connection portion 60, from the rear side. The contact portion 65 contacts the pet toilet 5 at a position away from the object connection portion 60 on one side in the width direction. The contact portion 66 contacts the pet toilet 5 at a position away from the object connection portion 60 on the opposite side in the width direction to the side on which the contact portion 65 is located. In a preferred example, a rubber protective member is attached to the column portion 46 at the contact portion 65, and a rubber protective member is attached to the column portion 47 at the contact portion 66. This prevents damage to the pet toilet 5 caused by contact between the contact portions 65, 66.

[0055] Here, the width dimension (total width) B0 of the pet toilet 5 along the width direction and the separation distance L0 between the contact portions 65, 66 along the width direction are defined (see FIG. 7 ). The width dimension B0 is greater than the separation distance L0. Therefore, the ratio of the width dimension B0 to the separation distance L0 is greater than 1. In one example such as FIG. 7 , the pet toilet 5 is symmetrical or approximately symmetrical in the width direction around the portion connected to the object connection portion 60, such as the plate member 57. The contact portions 65, 66 are arranged symmetrical or approximately symmetrical with each other in the width direction around the object connection portion 60. Therefore, in the pet toilet 5, the separation distance along the width direction from each of the widthwise ends to the portion connected to the object connection portion 60 is the same or approximately the same as the value B0 / 2. The separation distance along the width direction from each of the contact portions 65, 66 to the object connection portion 60 is the same or approximately the same as the value L0 / 2.

[0056] 1, 2, and 7, the installation plate portion 45, which is the freestanding installation portion, is adjacent to the lower side in the height direction of the pet toilet 5 connected to the object connection portion 60. Therefore, when the pet toilet 5, which is the object, is installed in the mounting fixture 2, the installation plate portion 45 is inserted between the pet toilet 5 and the installation surface 6, such as the floor, and is sandwiched between the pet toilet 5 and the installation surface 6 in the height direction.

[0057] 1 and 2, the sensor installation section 71 is formed on the extension section 10. A sensor 72 is installed on the sensor installation section 71. On the extension section 10, the sensor installation section 71 is provided between the module mounting section 13 and the object connection section 60 in the height direction. Therefore, the sensor 72 is disposed between the module mounting section 13 and the object connection section 60 in the height direction. In other words, the sensor 72 is disposed below the module mounting section 13 and the air treatment module 3 in the height direction. The sensor 72 is disposed above the object connection section 60, the contact sections 65, 66, and the installed pet litter box 5 in the height direction.

[0058] In one example, the sensor 72 is an odor sensor that detects odors caused by pet excrement. In another example, the sensor 72 is a proximity sensor, a human presence sensor, or the like that detects a pet's entry into the excretion area Q1 in the pet toilet 5 installed in the mounting fixture 2. In yet another example, the sensor 72 is an image sensor or a photographing device that captures an image of the pet toilet 5 as a subject, for example, by photographing the pet toilet 5 installed in the mounting fixture 2.

[0059] In one example shown in FIGS. 1 and 2 , the sensor 72 and the air treatment module 3 are connected by a connection cable 73. The connection cable 73 extends from the sensor 72 to the air treatment module 3 along the extension portion 10, and extends upward in the height direction to the air treatment module 3. As shown in FIG. 5 , wiring 75, such as a signal line, extends inside the connection cable 73. In the air treatment module 3, a control board 76 is disposed in the space 33 inside the exterior housing 20. In the air treatment device 1, the wiring 75 extends through the inside of the connection cable 73 and the inside of the air treatment module 3, and the sensor 72 is electrically connected to a control unit (control circuit) of the control board 76 via the wiring 75. Therefore, a signal indicating the detection result of the sensor 72 is transmitted to the control unit of the control board 76 via the wiring 75.

[0060] The control unit of the control board 76 is composed of a processor, an integrated circuit, or the like. The processor or integrated circuit constituting the control unit includes any of a CPU (Central Processing Unit), ASIC (Application Specific Integrated Circuit), microcomputer, FPGA (Field Programmable Gate Array), DSP (Digital Signal Processor), or the like. The control unit may include only one integrated circuit, or may include multiple integrated circuits, or the like. The control unit controls the operation of the fan 36 and the light emission operation of the ultraviolet light source 37 based at least on the detection result of the sensor 72. As a result, the operation of the air treatment module 3 is controlled based at least on the detection result of the sensor 72, and air treatment by the air treatment module 3 is controlled.

[0061] 1 and 2, the sensor 72 is disposed outside the exterior housing 20 and attached to the exterior housing 20 via a connection cable 73. In other words, the sensor 72 is retrofitted to the air treatment module 3. However, in one example, the sensor 72 may be mounted on the air treatment module 3, for example by being directly attached to the exterior housing 20. In another example, the sensor 72 may be provided separately from the air treatment module 3 and the mounting fixture 2. In this case, the sensor 72 is placed near the pet litter box 5 installed in the mounting fixture 2. A signal or the like indicating the detection result of the sensor 72 is transmitted to a control unit on a control board 76 of the air treatment module 3 via a wired or wireless connection.

[0062] 3, 5, etc., power is supplied to the air treatment module 3 from an external power source via a power supply line 77. In one example shown in FIG. 5, etc., a power supply board 78 is disposed in the space 32 inside the exterior housing 20. In the air treatment module 3, power from the external power source is converted by the power supply board 78 into power corresponding to the control unit of the control board 76, power corresponding to the fan 36, and power corresponding to the ultraviolet light source 37. The power converted by the power supply board 78 is then supplied to the control unit, the fan 36, and the ultraviolet light source 37, respectively.

[0063] As described above, in the mounting fixture 2 of this embodiment, the air treatment module 3 is attached to the module mounting part 13, and the extension part 10 extends downward in the height direction from the module mounting part 13. The extension part 10 is provided with an object connection part 60 including a magnet 61 and the like, and the pet litter box 5, which is the object that is the source of odor, is connected to the object connection part 60 from one side in the depth direction (the front side). As a result, the pet litter box 5 is placed in the mounting fixture 2 to which the air treatment module 3 is attached, and the air treatment module 3 attached to the mounting fixture 2 can efficiently deodorize odors from the pet litter box 5.

[0064] Furthermore, in the embodiment, the pet toilet 5 is installed in the mounting device 2 by connecting the pet toilet 5 to the object connection portion 60. Therefore, the air treatment module 3 is positioned with no or little misalignment in the depth and width directions relative to the installed pet toilet 5, and is positioned above the installed pet toilet 5 in the height direction. Because the pet toilet 5 and the air treatment module 3 are positioned as described above, when the air treatment module 3 is operating, air containing odor components of the odor generated in the pet toilet 5 is appropriately introduced into the air treatment module 3 through the opening 27. Then, after air treatment is performed on the air containing the odor components inside the air treatment module 3, the treated air is discharged to the outside of the air treatment module 3 through the opening 28. This improves the efficiency of the process of deodorizing the odor from the pet toilet 5.

[0065] Furthermore, when the pet toilet 5 is installed in the mounting fixture 2, an external force may be applied to the pet toilet 5 by the pet, the pet owner, etc. For example, when the pet enters the excretion area Q1 or when the pet leaves the excretion area Q1, the pet may apply an external force to the outer container 50 of the pet toilet 5. Furthermore, when cleaning the pet toilet 5, the pet owner, etc. applies an external force to the outer container 50 of the pet toilet 5 to remove the pet toilet 5 from the mounting fixture 2.

[0066] When an external force is applied to the pet toilet 5 as described above, a force resulting from the applied external force acts on the connection portion between the object connection portion 60 of the attachment device 2 and the pet toilet 5. In other words, when an external force is applied to the pet toilet 5, the force acts on the point of application located at the connection portion between the object connection portion 60 and the pet toilet 5, with the position where the external force is applied being the point of effort.

[0067] Fig. 8 schematically shows an example of a force acting on the pet toilet 5 installed in the attachment device 2 when a pet exits the excretion area Q1 of the pet toilet 5 in the embodiment etc. In Fig. 8, the pet toilet 5 etc. is shown as viewed from above in the height direction, and the point of application A1 located at the connection portion of the pet toilet 5 to the object connection portion 60 is shown. In the example of Fig. 8, the point of application A1 is located in the center in the width direction and at the rear end of the pet toilet 5 (outer container 50).

[0068] 8 also shows the coupling force F0 between the object connection part 60 of the attachment device 2 and the pet toilet 5 as the force that maintains the connection of the pet toilet 5 to the object connection part 60 of the attachment device 2. When the pet toilet 5 is installed in the attachment device 2, a force greater than the coupling force F0 acts forward at the application point A1, causing the pet toilet 5 to be disconnected from the object connection part 60 and the pet toilet 5 to be removed from the attachment device 2.

[0069] In one example, such as FIG. 8 , an external force F1e is applied to the force point E1 by a pet or the like exiting the excretion area Q1 of the pet toilet 5. The external force F1e is applied to the force point E1 toward the front by the exiting pet or the like. In the pet toilet 5, the force point E1 is located in the center in the width direction and at the front end. Therefore, the force point E1 is located forward of the action point A1. The force point E1 is not shifted, or is barely shifted, in the width direction relative to the action point A1. When the external force F1e is applied to the force point E1, a force F1a acts toward the front at the action point A1, and the force F1a has the same or approximately the same magnitude as the external force F1e applied to the force point E1.

[0070] 8, the pet toilet 5 will not be released from the object connection part 60 unless the force F1a acting on the point of application A1 is greater than the connecting force F0. In other words, even if an external force F1e is applied to the force point E1 toward the front, the pet toilet 5 will not be released from the object connection part 60 as long as the applied external force F1e is equal to or less than the connecting force F0. This effectively prevents the pet toilet 5 from being detached from the attachment device 2 by an external force from the pet, for example, when the pet leaves the excretion area Q1.

[0071] 9 schematically shows an example of a force acting on the pet toilet 5 installed in the attachment device 2 when a pet enters the excretion area Q1 of the pet toilet 5 in the embodiment etc. In FIG. 9, the pet toilet 5 etc. is shown as viewed from above in the height direction, and the above-mentioned point of action A1 located at the connection part of the pet toilet 5 to the object connection part 60 is shown. In the example of FIG. 9, a force greater than the connecting force F0 acts forward at the point of action A1, thereby releasing the connection of the pet toilet 5 to the object connection part 60 and removing the pet toilet 5 from the attachment device 2.

[0072] In one example, such as FIG. 9 , an external force F2e is applied to the force point E2 by a pet or the like entering the excretion area Q1 of the pet toilet 5. In the pet toilet 5, the force point E2, like the force point E1 described above, is located in the center in the width direction and at the front end. Therefore, the force point E2 is located forward of the action point A1. The force point E2 is not, or is barely, misaligned in the width direction relative to the action point A1. However, in the example, such as FIG. 9 , an external force F2e is applied rearward at the force point E2 by the entering pet or the like. Then, as a result of the external force F2e being applied to the force point E2, a force F2a acts rearward at the action point A1, and the force F2a has the same or approximately the same magnitude as the external force F2e applied to the force point E2.

[0073] 9, etc., a force F2a acts toward the rear at the point of application A1. Therefore, regardless of the magnitude of the force F2a, the pet toilet 5 is not released from the object connection part 60. In other words, even if an external force F2e is applied toward the rear at the force point E2, the pet toilet 5 is not released from the object connection part 60, regardless of the magnitude of the external force F2e.

[0074] FIG. 10 schematically shows another example of the force acting on the pet toilet 5 installed on the attachment device 2 when a pet enters the excretion area Q1 of the pet toilet 5 in the embodiment, etc., different from that shown in FIG. 9 . In FIG. 10 , the pet toilet 5 is also shown as viewed from above in the height direction, and the aforementioned point of application A1, which is located at the connection portion of the pet toilet 5 to the object connection portion 60, is shown. In the example of FIG. 10 , a force greater than the coupling force F0 acts forward at the point of application A1, thereby disconnecting the pet toilet 5 from the object connection portion 60 and removing the pet toilet 5 from the attachment device 2. In this example, similar to the example of FIG. 7 , the pet toilet 5 is symmetrical or approximately symmetrical in the width direction around the portion connected to the object connection portion 60, such as the plate member 57. The contact portions 65 and 66 are arranged symmetrical or approximately symmetrical with each other in the width direction around the object connection portion 60.

[0075] In one example shown in FIG. 10 etc., an external force F3e is applied to the force point E3 by a pet or the like entering the excretion area Q1 of the pet toilet 5. In the pet toilet 5, the force point E3 is located at the end on one side in the width direction (the side indicated by the arrow W2) and at the end on the front side. Therefore, the force point E3 is located forward of the action point A1. The force point E3 is also located away from the action point A1 in the width direction. An external force F3e is applied rearward to the force point E3 by the entering pet or the like.

[0076] 10 etc., when an external force F3e is applied to the force point E3, a force that rotates the contact portion 66 about the fulcrum P1 acts on the pet toilet 5. In other words, a force that passes through the fulcrum P1 and rotates the pet toilet 5 about an axis along the height direction acts on the pet toilet 5. As a result, a force F3a acts forward at the force point A1, and the magnitude of the force F3a is the same as or approximately the same as the value obtained by multiplying the external force F3e applied to the force point E3 by (B0-L0) / L0.

[0077] 10 and other examples, the pet toilet 5 will not be released from the object connection part 60 unless the force F3a acting on the point of application A1 is greater than the coupling force F0. Therefore, even if an external force F3e is applied to the force point E3 toward the rear, the pet toilet 5 will not be released from the object connection part 60 as long as the value obtained by multiplying the applied external force F3e by (B0-L0) / L0 is equal to or less than the coupling force F0. Here, if the width dimension (total width) B0 of the pet toilet 5 is twice the separation distance L0 between the contact parts 65, 66 along the width direction, the pet toilet 5 will not be released from the object connection part 60 as long as the magnitude of the external force F3e is equal to or less than the coupling force F0.

[0078] When the width dimension (total width) B0 is 3, 4, 5, or 6 times the separation distance L0, the pet toilet 5 will not be released from the object connection part 60 if the external force F3e is doubled, tripled, quadrupled, or quintuple times the bonding force F0 or less, respectively. Furthermore, when the width dimension (total width) B0 is 3 / 2, 4 / 3, 5 / 4, or 6 / 5 times the separation distance L0, the pet toilet 5 will not be released from the object connection part 60 if the external force F3e is 1 / 2, 1 / 3, 1 / 4, or 1 / 5 times the bonding force F0 or less, respectively. Therefore, the smaller the ratio of the width dimension (total width) B0 to the separation distance L0, the greater the external force F3e required to release the pet toilet 5 from the object connection part 60, making it more difficult for the external force F3e to detach the pet toilet 5 from the attachment fixture 2.

[0079] On the other hand, the greater the ratio of the width dimension (total width) B0 to the separation distance L0, the smaller the external force F3e required to disconnect the pet toilet 5 from the object connection portion 60, making it easier for the external force F3e to remove the pet toilet 5 from the attachment device 2. In the embodiments, from the viewpoint of making it difficult for the external force F3e to remove the pet toilet 5 from the attachment device 2, it is preferable that the ratio of the width dimension (total width) B0 to the separation distance L0 be 5 times or less. Note that even when the end portion opposite the force point E3 in the width direction serves as the force point, the magnitude of the external force applied to the force point and the magnitude of the force acting on the action point A1 will be the same as the example in FIG. 10, except that the contact portion 65 serves as the fulcrum.

[0080] As described above in the examples of Figures 9 and 10, in the present embodiment and the like, it is possible to prevent the pet toilet 5 from being detached from the attachment device 2 due to external force from the pet when the pet enters the excretion area Q1, etc. In particular, by making the ratio of the width dimension (total width) B0 to the separation distance L0 relatively small, for example, by setting it to 5 times or less, it is possible to effectively prevent the pet toilet 5 from being detached from the attachment device 2 due to external force from the pet when the pet enters the excretion area Q1, etc. As described above, in the present embodiment, it is possible to effectively prevent the pet toilet 5 from being detached from the attachment device 2 due to external force from the pet.

[0081] FIG. 11 schematically shows an example of a force acting on the pet toilet 5 installed in the attachment device 2 when an owner or the like removes the pet toilet 5 from the attachment device 2 in the embodiment or the like. In FIG. 11 , the pet toilet 5 or the like is shown as viewed from above in the height direction, and the aforementioned point of application A1, which is located at the connection portion of the pet toilet 5 to the object connection portion 60, is shown. In the example of FIG. 11 , a force greater than the coupling force F0 acts forward at the point of application A1, thereby disconnecting the pet toilet 5 from the object connection portion 60 and removing the pet toilet 5 from the attachment device 2. In this example, similar to the example of FIG. 7 , the pet toilet 5 is symmetrical or approximately symmetrical in the width direction around the portion of the plate member 57 or the like that is connected to the object connection portion 60. The contact portions 65, 66 are arranged symmetrical or approximately symmetrical to each other in the width direction around the object connection portion 60.

[0082] In one example, such as FIG. 11 , an external force F4e is applied to force point E4 by an owner or the like. In the pet toilet 5, force point E4, like force point E3, is located at the end on one side in the width direction (the side indicated by arrow W2) and at the end on the front side. Therefore, force point E4 is located forward of point of action A1. And force point E3 is located away from point of action A1 in the width direction. However, external force F4e is applied forward to point of action E4 by an owner or the like.

[0083] 11 etc., when an external force F4e is applied to the force point E4, a force that rotates the contact portion 65 about the fulcrum P2 acts on the pet toilet 5. In other words, a force that passes through the fulcrum P2 and rotates the pet toilet 5 about an axis along the height direction acts on the pet toilet 5. As a result, a force F4a acts forward at the force point A1, and the magnitude of the force F4a is the same as or approximately the same as the value obtained by multiplying the external force F4e applied to the force point E4 by (B0+L0) / L0.

[0084] 11, etc., when the force F4a acting on the point of application A1 becomes greater than the coupling force F0, the pet toilet 5 is disconnected from the object connection part 60. Therefore, when an external force F4e is applied to the force point E4 toward the front, if the value obtained by multiplying the applied external force F4e by (B0+L0) / L0 is greater than the coupling force F0, the pet toilet 5 is disconnected from the object connection part 60. Here, if the width dimension (total width) B0 of the pet toilet 5 is twice the separation distance L0 between the contact parts 65, 66 along the width direction, the pet toilet 5 is disconnected from the object connection part 60 if the value three times the external force F4e is greater than the coupling force F0.

[0085] When the width dimension (total width) B0 is 3, 4, 5, or 6 times the separation distance L0, if the 4-fold, 5-fold, 6-fold, or 7-fold value of the external force F4e is greater than the bonding force F0, the pet toilet 5 will be disconnected from the object connection part 60. Furthermore, when the width dimension (total width) B0 is 3 / 2, 4 / 3, 5 / 4, or 6 / 5 times the separation distance L0, if the 5 / 2-fold, 7 / 3-fold, 9 / 4-fold, or 11 / 5-fold value of the external force F4e is greater than the bonding force F0, the pet toilet 5 will be disconnected from the object connection part 60. Therefore, the greater the ratio of the width dimension (total width) B0 to the separation distance L0, the smaller the external force F4e required to disconnect the pet toilet 5 from the object connection part 60, making it easier to remove the pet toilet 5 from the attachment fixture 2 by the external force F4e.

[0086] On the other hand, the smaller the ratio of the width dimension (total width) B0 to the separation distance L0, the greater the external force F4e required to disconnect the pet toilet 5 from the object connection portion 60, making it more difficult for the pet toilet 5 to be removed from the attachment device 2 by the external force F3e. However, in either case, the separation distance L0 is smaller than the width dimension (total width) B0, and the ratio of the width dimension (total width) B0 to the separation distance L0 is greater than 1. Therefore, in either case, the force F4a acting on the point of application A1 is more than twice the external force F4e applied to the point of application E4. Note that even when the end opposite the point of application E4 in the width direction serves as the point of application, the magnitude of the external force applied to the point of application and the magnitude of the force acting on the point of application A1 are similar to the example shown in FIG. 11, except that the contact portion 66 serves as the fulcrum.

[0087] As described above in the example of Figure 11 etc., in this embodiment etc., the owner etc. can easily remove the pet toilet 5 from the attachment fixture 2 by applying a forward external force to one end of the width direction of the pet toilet 5, even if the applied external force is small. This reduces the effort required to remove the pet toilet 5 from the attachment fixture 2 when cleaning the pet toilet 5 etc.

[0088] Here, in the example of Fig. 8, a minimum value F1emin of the external force F1e at the force point E1 required to disconnect the pet toilet 5 from the object connection portion 60 is defined. Also, in the example of Fig. 10, a minimum value F3emin of the external force F3e at the force point E3 required to disconnect the pet toilet 5 from the object connection portion 60 is defined. In the example of Fig. 11, a minimum value F4emin of the external force F4e at the force point E4 required to disconnect the pet toilet 5 from the object connection portion 60 is defined. The magnification η1 of the minimum value F3emin to the minimum value F1emin is L0 / (B0-L0), and the magnification η2 of the minimum value F4emin to the minimum value F1emin is L0 / (B0+L0). Also, the magnification η3 of the minimum value F3emin to the minimum value F4emin is (B0+L0) / (B0-L0).

[0089] Here, when the width dimension (total width) B0 is 3 / 2, 2, 3, 4, 5, or 6 times the separation distance L0, the magnification η3 of the minimum value F3emin to the minimum value F4emin is 5, 3, 2, 1.67, 1.5, or 1.4, respectively. The magnification η3 of the minimum value F3emin to the minimum value F4emin increases as the magnification of the width dimension (total width) B0 to the separation distance L0 decreases. In embodiments, the magnification η3 is preferably 1.5 or less. From this perspective, in embodiments, the magnification of the width dimension (total width) B0 to the separation distance L0 is preferably 5 or less.

[0090] In one example of the above-described embodiments, the mounting fixture 2 including the extension portion 10 is installed in a freestanding state on the installation surface 6 by means of the installation plate portion 45, which serves as a freestanding installation portion. The provision of the installation plate portion 45 effectively prevents the mounting fixture 2 installed on the installation surface 6, such as the floor, and the air treatment module 3 attached to the mounting fixture 2 from tipping over.

[0091] Furthermore, in one example of this embodiment, the installation plate 45, which serves as the freestanding installation part, is placed on the installation surface 6 adjacent to the lower side in the height direction of the pet toilet 5 connected to the object connection part 60. As a result, the installation plate 45 is placed between the pet toilet 5 and the installation surface 6, so there is no need to secure a space on the installation surface 6 for placing the installation plate 45 separately from the space on the installation surface 6 for placing the pet toilet 5. This makes it possible to reduce the area of ​​the portion of the installation surface 6 where the pet toilet 5 and the air treatment device 1 are placed.

[0092] Furthermore, in one example of this embodiment, a sensor installation section 71 is provided in the extension section 10 between the module mounting section 13 and the object connection section 60. With this configuration, the sensor 72 is positioned in the height direction between the air treatment module 3 and the installed pet toilet 5. This allows the sensor 72 to appropriately detect either the odor generated in the pet toilet 5 or the condition of the pet toilet 5.

[0093] Furthermore, in one example of this embodiment, a connection cable 73 is extended from the sensor 72 to the air treatment module 3 along the extension portion 10, and the connection cable 73 connects the air treatment module 3 and the sensor 72. As a result, even in a configuration in which the sensor 72 is externally attached to the air treatment module 3, signals and the like indicating the detection results of the sensor 72 are appropriately transmitted to the control unit of the control board 76 via the wiring 75 of the connection cable 73. This allows the control unit of the air treatment module 3 to appropriately acquire the detection results of the sensor 72.

[0094] In the above-described embodiment, a pet toilet 5 is given as an example of an object to be installed in the attachment device 2, but the object to be installed in the attachment device 2 is not limited to this as long as it is an odor source. In one example, instead of a pet toilet 5, a nursing care bed may be installed in the attachment device 2 as an odor source object. In another example, a container for containing waste and the like that causes a foul odor is installed in the attachment device 2 as an object. In these examples, the odor source object is installed in the attachment device 2 in the same manner as in any of the above-described embodiments.

[0095] According to at least one of these embodiments, in the mounting device, the extension portion extends downward in the height direction from the module mounting portion, and the object is connected to the object connection portion of the extension portion from one side in a depth direction intersecting the height direction. The first contact portion contacts the object at a position away from the object connection portion on one side in a width direction intersecting both the height direction and the depth direction of the extension portion, and the second contact portion contacts the object at a position away from the object connection portion on the side of the extension portion opposite the side on which the first contact portion is located in the width direction. This makes it possible to provide a mounting device in which an odor-producing object is placed and which can efficiently deodorize odors from the object using an attached air treatment module, and an air treatment device including the mounting device and an air treatment module attached to the mounting device.

[0096] 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.
