DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the drawings, the same or equivalent elements are designated by the same reference numerals, and redundant description will be omitted.

[0009] 1. First embodiment 1.1 Appearance of the blower Fig. 1 is a perspective view schematically illustrating a blower device of a first embodiment. Fig. 2 is a front view schematically illustrating the blower device of the first embodiment. Fig. 3 is a left side view schematically illustrating the blower device of the first embodiment. Arrows indicating the upward, downward, leftward, rightward, forward, and backward directions of the blower device are drawn in Figs. 1 to 3.

[0010] The air blower 1 of the first embodiment shown in Figures 1 to 3 is an air purifier. Therefore, the air blower 1 draws in air, purifies the drawn-in air, and blows out the purified air. The air blower 1 may be an air blower other than an air purifier. For example, the air blower 1 may be a humidifier, a dehumidifier, a heater, a cooler, a blower, etc.

[0011] The blower 1 has a rectangular parallelepiped shape. Therefore, the blower 1 has an upper surface 1T, a lower surface 1B, and a side surface 1S. The upper surface 1T and the lower surface 1B face upward and downward, respectively. The side surface 1S faces in a direction perpendicular to the upward and downward directions. The side surface 1S has a left surface 1SL, a right surface 1SR, a front surface 1SF, and a rear surface 1SB. The left surface 1SL, the right surface 1SR, the front surface 1SF, and the rear surface 1SB face leftward, rightward, forward, and rearward, respectively.

[0012] The blower 1 is installed so that the upward and downward directions correspond to the vertically upward and vertically downward directions, respectively, and the leftward, rightward, forward, and backward directions correspond to the horizontal directions.

[0013] The blower 1 draws in air from the left side 1SL and the right side 1SR except near the upper ends thereof, and blows out the air from the left side 1SL, the right side 1SR, the front side 1SF and the rear side 1SB thereof near the upper ends thereof.

[0014] As shown in FIGS. 1 to 3, the blower 1 includes a top panel 12, a left panel 13L, a right panel 13R, a front panel 13F, and a rear panel 13B.

[0015] The top panel 12, left panel 13L, right panel 13R, front panel 13F, and rear panel 13B are arranged on the upper surface 1T, left surface 1SL, right surface 1SR, front surface 1SF, and rear surface 1SB of the blower 1, respectively.

[0016] 1.2 Structure of the blower Fig. 4 is a cross-sectional view of the blower device of the first embodiment, taken along a cutting line BB in Fig. 5. Fig. 5 is a cross-sectional view of the blower device of the first embodiment, taken along a cutting line AA in Fig. 4. Arrows indicating the upward, downward, leftward, rightward, forward, and backward directions of the blower device are depicted in Figs. 4 and 5.

[0017] As shown in Figures 4 and 5, the air blower 1 includes a main body 11, a top panel 12, a left panel 13L, a right panel 13R, a front panel 13F, a rear panel 13B, a left pre-filter 14L, a right pre-filter 14R, a deodorizing filter 15, a high-efficiency particulate air (HEPA) filter 16, a blower 17, and an ion generator 18.

[0018] The main body 11 has a rectangular parallelepiped shape. Therefore, the main body 11 has an upper surface 11T, a lower surface 11B, and a side surface 11S. The upper surface 11T and the lower surface 11B face upward and downward, respectively. The side surface 11S faces in a direction perpendicular to the upward and downward directions. The side surface 11S has a left surface 11SL, a right surface 11SR, a front surface 11SF, and a rear surface 11SB. The left surface 11SL, the right surface 11SR, the front surface 11SF, and the rear surface 11SB face leftward, rightward, forward, and rearward, respectively.

[0019] A second air passage 22 is formed in the main body 11. The second air passage 22 has a left inlet 22L formed on the left surface 11SL and a right inlet 22R formed on the right surface 11SR. The second air passage 22 has a front outlet 22F formed on the front surface 11SF. The second air passage 22 has a connection portion 22C on the top surface 11T of the main body 11. The second air passage 22 leads from the left inlet 22L and the right inlet 22R to the front outlet 22F and the connection portion 22C. As a result, the second air passage 22 guides air from the left inlet 22L and the right inlet 22R to the front outlet 22F and the connection portion 22C. As a result, air AF flows from the left inlet 22L and the right inlet 22R via the second air passage 22 to the front outlet 22F and the connection portion 22C.

[0020] The top plate 12 has a plate-like shape. Therefore, the top plate 12 has an upper surface 12T and a lower surface 12B. The upper surface 12T and the lower surface 12B face upward and downward, respectively.

[0021] The underside 12B of the top panel 12 faces the upper side 11T of the main body 11, with a first air passage 21 interposed therebetween. The first air passage 21 has a connection part 21C on the upper side 11T. The first air passage 21 has an air outlet 21S on a side surface 1S of the blower device 1. As a result, the first air passage 21 guides air from the connection part 21C to the air outlet 21S. As a result, the air AF flows from the connection part 21C through the first air passage 21 to the air outlet 21S.

[0022] Connection portion 21C of first air passage 21 is connected to connection portion 22C of second air passage 22. As a result, first air passage 21 communicates with second air passage 22. As a result, first air passage 21 guides air that has been guided by second air passage 22. As a result, air AF flows from left air inlet 22L and right air inlet 22R through second air passage 22, connection portion 22C, connection portion 21C, and first air passage 21 to outlet 21S.

[0023] Connection portion 21C of first air passage 21 is located rearwardly offset from the center of top surface 11T of main body 11. Air outlets 21S are formed around the entire periphery of side surface 1S of blower 1. For this reason, air outlets 21S include left air outlet 21SL, right air outlet 21SR, front air outlet 21SF, and rear air outlet 21SB, which are located on left surface 1SL, right surface 1SR, front surface 1SF, and rear surface 1SB of blower 1, respectively. For this reason, air AF generally travels leftward, rightward, upward, and downward from connection portion 21C and is blown out from left air outlet 21SL, right air outlet 21SR, front air outlet 21SF, and rear air outlet 21SB, respectively.

[0024] The left panel 13L, the right panel 13R, the front panel 13F, and the rear panel 13B each have a lattice shape. Therefore, the left panel 13L, the right panel 13R, the front panel 13F, and the rear panel 13B each allow air to pass through. The left panel 13L, the right panel 13R, the front panel 13F, and the rear panel 13B are respectively disposed on the left surface 11SL, the right surface 11SR, the front surface 11SF, and the rear surface 11SB of the main body 11. As a result, the left panel 13L and the right panel 13R are respectively disposed on the left intake port 22L and the right intake port 22R of the second air passage 22 on the left surface 11SL and the right surface 11SR. As a result, the left panel 13L and the right panel 13R allow air AF drawn into the left intake port 22L and the right intake port 22R to pass through.

[0025] The left prefilter 14L and the right prefilter 14R each have a plate-like shape. Each of the left prefilter 14L and the right prefilter 14R allows air to pass through while blocking coarse dust particles. The left prefilter 14L is disposed between the left panel 13L and the left surface 11SL of the main body 11. The right prefilter 14R is disposed between the right panel 13R and the right surface 11SR of the main body 11. The left prefilter 14L and the right prefilter 14R are attached to the left surface 11SL and the right surface 11SR, respectively. The left prefilter 14L and the right prefilter 14R cover the left intake port 22L and the right intake port 22R of the second air duct 22, respectively. This allows air that passes through the left panel 13L and is drawn into the left intake port 22L to pass through the left prefilter 14L while removing coarse dust particles from the passing air. The right pre-filter 14R allows air that passes through the right panel 13R and is drawn into the right intake port 22R to pass therethrough, and removes coarse dust particles from the air that passes through.

[0026] Each of the deodorizing filter 15 and the HEPA filter 16 has a plate-like shape. The deodorizing filter 15 allows air to pass through but blocks odor components from passing through. The HEPA filter 16 allows air to pass through but blocks fine particles from passing through.

[0027] The deodorizing filter 15 and the HEPA filter 16 are stacked one on top of the other. The deodorizing filter 15 and the HEPA filter 16 are arranged in the second air duct 22. The deodorizing filter 15 and the HEPA filter 16 are arranged along the left air inlet 22L of the second air duct 22. The deodorizing filter 15 is arranged upstream of the HEPA filter 16 in the second air duct 22. This allows the air drawn into the left air inlet 22L to pass through the deodorizing filter 15 and removes odor components from the passing air. The HEPA filter 16 allows the air that has passed through the deodorizing filter 15 to pass through and removes fine particles from the passing air.

[0028] Fan 17 is disposed in second air passage 22. Fan 17 is disposed downstream of deodorizing filter 15 and HEPA filter 16 in second air passage 22. Fan 17 draws air from the upstream side of second air passage 22 and blows out the drawn air to the downstream side of second air passage 22. In this way, fan 17 blows air AF.

[0029] Ion generator 18 is arranged in second air passage 22. Ion generator 18 is arranged downstream of air blower 17 in second air passage 22. Ion generator 18 generates ions. As a result, ion generator 18 causes the ions to be contained in the air blown by wind AF.

[0030] 1.3 Left and right panels partially open 6 and 7 are perspective views of the blower of the first embodiment, each showing a state in which the left and right panels of the blower are half-open. FIG. 8 is a front view of the blower of the first embodiment, each showing a state in which the left and right panels of the blower are half-open and the front panel of the blower is removed. FIG. 9 is a rear view of the blower of the first embodiment, each showing a state in which the left and right panels of the blower are half-open and the rear panel of the blower is removed. Arrows indicating the upward, downward, leftward, rightward, forward, and rearward directions of the blower are depicted in FIGS. 6 to 9.

[0031] As shown in Figures 6 to 9, the blower device 1 comprises a main body 11, a left pre-filter 14L, a right pre-filter 14R, a left panel 13L, a right panel 13R, a left front stopper 31LF, a left rear stopper 31LB, a right front stopper 31RF and a right rear stopper 31RB.

[0032] The left pre-filter 14L and the right pre-filter 14R are detachable from the left surface 11SL and the right surface 11SR of the main body 11. Each of the left pre-filter 14L and the right pre-filter 14R is a replacement part that can be replaced with a new pre-filter when it becomes dirty, etc. Replacement parts other than the left pre-filter 14L and the right pre-filter 14R may be detachable from the left surface 11SL and / or the right surface 11SR of the main body 11.

[0033] The left panel 13L and the right panel 13R face the left surface 11SL and the right surface SR of the main body 11, sandwiching the left pre-filter 14L and the right pre-filter 14R therebetween. The left panel 13L and the right panel 13R rotate around a rotation axis parallel to the front-to-rear direction, located near the bottom end 41L of the left panel 13L and the bottom end 41R of the right panel 13R. This allows the left panel 13L and the right panel 13R to open downward. A gap 51L is formed between the left panel 13L and the main body 11 and the left pre-filter 14L. A gap 51R is formed between the right panel 13R and the main body 11 and the right pre-filter 14R. The gaps 51L and 51R widen when the left panel 13L and the right panel 13R open downward. The amount of widening of the gaps 51L and 51R when the left panel 13L and the right panel 13R open downward increases the further upward. Therefore, when the left panel 13L and the right panel 13R are opened downward, the left surface 11SL and the right surface SR of the main body 11 can be easily reached from above. Also, when the left panel 13L and the right panel 13R are opened downward, the left pre-filter 14L and the right pre-filter 14R can be easily reached from above. Therefore, when the left panel 13L and the right panel 13R are opened downward, the left pre-filter 14L and the right pre-filter 14R can be easily replaced.

[0034] The left panel 13L and the right panel 13R are fully opened by rotating 90° or more around the rotation axis. The left panel 13L and the right panel 13R are half-open by rotating less than 90° around the rotation axis. The left front stopper 31LF and the left rear stopper 31LB limit the opening angle of the left panel 13L to a value equal to or less than the half-open state. The right front stopper 31RF and the right rear stopper 31RB limit the opening angle of the right panel 13R to a value equal to or less than the half-open state. This prevents the left panel 13L and the right panel 13R from being fully opened, thereby preventing the air blower 1 from occupying a large floor area. The opening angle in the half-open state is, for example, 30° or less, preferably 20° or less, and more preferably 5° to 10°.

[0035] 1.4 Handle As shown in FIGS. 6 and 7 , the left side 11SL and the right side SR of the main body 11 have regions 61L and 61R, respectively, that face the left panel 13L and the right panel 13R when the left panel 13L and the right panel 13R are closed. Handles 62L and 62R are formed in the regions 61L and 61R, respectively. When the left panel 13L and the right panel 13R are closed, the regions 61L and 61R are hidden by the left panel 13L and the right panel 13R, respectively. Therefore, when the left panel 13L and the right panel 13R are closed, the handles 62L and 62R are hidden by the left panel 13L and the right panel 13R, respectively. Therefore, the handles 62L and 62R do not impose any restrictions on the design of the side surface 1S of the blower 1. Furthermore, when the left panel 13L and the right panel 13R are half-opened, the areas 61L and 61R can be easily reached from above, respectively. Therefore, when the left panel 13L and the right panel 13R are half-opened, the handles 62L and 62R can be easily reached, respectively. Therefore, the blower 1 can be easily moved by holding the handles 62L and 62R.

[0036] The handles 62L and 62R are located above the left and right suction ports 22L and 22R, respectively, and are preferably located at the upper ends of the regions 61L and 61R, respectively, which makes it easier to reach the handles 62L and 62R from above.

[0037] 1.5 Stopper 6 to 9, the left panel 13L and the right panel 13R have lower ends 41L and 41R, respectively. The main body 11 supports the vicinity of the lower ends 41L and 41R so that the left panel 13L and the right panel 13R can rotate around rotation axes that are located near the lower ends 41L and 41R and that are parallel to the front-to-rear direction. In this way, the main body 11 supports the lower ends 41L and 41R so that the left panel 13L and the right panel 13R can be opened downward.

[0038] Each of the stoppers 31 included in the left front stopper 31LF, the left rear stopper 31LB, the right front stopper 31RF and the right rear stopper 31RB includes a stay 71.

[0039] 6 to 9, the stay 71 includes a first mounting portion 81, a second mounting portion 82, and a wire 83. The first mounting portions 81 of the stays 71 of the left front stopper 31LF, the left rear stopper 31LB, the right front stopper 31RF, and the right rear stopper 31RB are respectively attached to the front end of the left surface 11SL of the main body 11, the rear end of the left surface 11SL of the main body 11, the front end of the right surface 11SR of the main body 11, and the rear end of the right surface 11SR of the main body 11. The second mounting portions 82 of the stays 71 of the left front stopper 31LF, the left rear stopper 31LB, the right front stopper 31RF, and the right rear stopper 31RB are respectively attached to the front end of the left panel 13L, the rear end of the left panel 13L, the front end of the right panel 13R, and the rear end of the right panel 13R. The stays 71 restrict the distance from the first mounting portion 81 to the second mounting portion 82 from becoming longer than the maximum length of the wire 83. The stays 71 of the left front stopper 31LF and the left rear stopper 31LB are positioned higher than the lower end 41L. The stays 71 of the right front stopper 31RF and the right rear stopper 31RB are positioned higher than the lower end 41R. As a result, the stays 71 of the left front stopper 31LF and the left rear stopper 31LB limit the opening degree of the left panel 13L. In addition, the stays 71 of the right front stopper 31RF and the right rear stopper 31RB limit the opening degree of the right panel 13R.

[0040] One end of the wire 83 is coupled to the first attachment portion 81. The other end of the wire 83 is coupled to the second attachment portion .

[0041] The wire 83 may be replaced with a flexible linear body other than the wire 83. For example, the wire 83 may be replaced with a chain. The wire 83 may be replaced with a deformable rod-like structure other than a flexible linear body. For example, the wire 83 may be replaced with an arm having bones connected via a movable joint.

[0042] 1.6 Stopper pipe FIG. 10 is a plan view schematically illustrating a stopper provided in the blower device of the first modified example of the first embodiment.

[0043] In a first modification of the first embodiment, as shown in FIG. 10, each stopper 31 includes a plurality of pipes 91.

[0044] A wire 83 is passed through the multiple pipes 91. As a result, when the left panel 13L is closed, the wire 83 of the left front stopper 31LF and the left rear stopper 31LB hangs down due to the weight of the multiple pipes 91, which makes it possible to prevent the wire 83 of the left front stopper 31LF and the left rear stopper 31LB from becoming tangled inside the main body 11. Furthermore, when the right panel 13R is closed, the wire 83 of the right front stopper 31RF and the right rear stopper 31RB hangs down due to the weight of the multiple pipes 91, which makes it possible to prevent the wire 83 of the right front stopper 31RF and the right rear stopper 31RB from becoming tangled inside the main body 11.

[0045] 1.7 Removing the Secondary Mounting and Panel Fig. 11 is an enlarged perspective view schematically illustrating a left panel and a left front stopper provided in the blower of the first embodiment. Fig. 12 is an enlarged perspective view schematically illustrating a right panel and a right front stopper provided in the blower of the first embodiment. Arrows indicating the upward, downward, leftward, rightward, forward, and backward directions of the blower are drawn in Figs. 11 and 12.

[0046] As shown in Fig. 11, each stopper 31L included in the left front stopper 31LF and the left rear stopper 31LB includes a pin 101L, a ring 102L, and a wire 103R. As shown in Fig. 12, each stopper 31R included in the right front stopper 31RF and the right rear stopper 31RB includes a pin 101R, a ring 102R, and a wire 103R.

[0047] Holes 101La and 101Ra are formed in one ends of the pins 101L and 101R, respectively. Rings 102L and 102R are passed through the holes 101La and 101Ra, respectively. One ends of wires 103L and 103R are tied to the ring 102L. As a result, one ends of wires 103L and 103R are coupled to one ends of pins 101L and 101R, respectively, via rings 102L and 102R.

[0048] A pin insertion hole 111L and a pin receiver 112L are formed in the left panel 13L. A pin insertion hole 111R and a pin receiver 112R are formed in the right panel 13R. The pins 101L and 101R are inserted into the pin insertion hole 111L and the pin insertion hole 111R, respectively, until the other ends of the pins 101L and 101R abut against the pin receivers 112L and 112R. When the pin 101L is inserted into the pin insertion hole 111L until the other end of the pin abuts against the pin receiver 112L, the left panel 13L opens, and the wire 103R is stretched taut, the longitudinal direction of the pin 101L and the longitudinal direction of the wire 103R form an acute angle. When the pin 101R is inserted into the hole 101Ra until the other end of the pin 101R abuts the pin receiver 112R, the right panel 13R is opened, and the wire 103R is stretched taut, the longitudinal direction of the pin 101R and the longitudinal direction of the wire 103R form an acute angle. This prevents the pin 101L from coming out of the pin insertion hole 111L when the left panel 13L is opened. Also, when the right panel 13R is opened, the pin 101R is prevented from coming out of the pin insertion hole 111R. However, when a force is applied from the other end of the pin 101L toward one end of the pin 101L, the pin 101R comes out of the pin insertion hole 111L. When a force is applied from the other end of the pin 101R toward one end of the pin 101R, the pin 101R comes out of the pin insertion hole 111R.

[0049] The pins 101L and 101R constitute the second mounting portion 82 of each stopper 31L and each stopper 31R, respectively. This allows the second mounting portion 82 of each stopper 31L and each stopper 31R to be detached from the left panel 13L and the right panel 13R, respectively. A structure other than the pin 101L may constitute the second mounting portion 82 of each stopper 31L. A structure other than the pin 101R may constitute the second mounting portion 82 of each stopper 31R. For example, a hook that is hooked onto a hook receiver formed on the left panel 13L may constitute the second mounting portion 82 of each stopper 31L. A hook that is hooked onto a hook receiver formed on the right panel 13R may constitute the second mounting portion 82 of each stopper 31R.

[0050] The left panel 13L and the right panel 13R can be removed from the main body 11 when the second mounting portions 82 of each stopper 31L and each stopper 31R are removed from the left panel 13L and the right panel 13R, respectively. When the left panel 13L is removed from the left panel 13L, the left surface 11SL of the main body 11 is completely exposed. When the right panel 13R is removed from the right panel 13R, the right surface 11SR of the main body 11 is completely exposed. Therefore, when the left panel 13L is removed from the main body 11, maintenance of the main body 11 can be easily performed from the left side of the main body 11. When the right panel 13R is removed from the main body 11, maintenance of the main body 11 can be easily performed from the right side of the main body 11.

[0051] 1.8 Keeping the panel closed 13 and 14 are enlarged perspective views schematically illustrating the state in which the left and right panels of the air blower of the first embodiment are half-opened.

[0052] 13 and 14, the main body 11 includes a receiving seat 121L and a receiving seat 121R. The left panel 13L and the right panel 13R include a push latch body 131L and a push latch body 131R, respectively.

[0053] The receiving seat 121L and the push latch body 131L constitute a push latch. The receiving seat 121R and the push latch body 131R constitute a push latch. The push latch body 131L and the push latch body 131R are attached to and detached from the receiving seat 121L and the receiving seat 121R, respectively.

[0054] When the push latch body 131L is pushed toward the receiving seat 121L while it is not engaged with the receiving seat 121L, the push latch body 131L engages with the receiving seat 121L. The state in which the push latch body 131L is engaged with the receiving seat 121L is maintained even after the push of the push latch body 131L toward the receiving seat 121L has ended. When the push latch body 131R is pushed toward the receiving seat 121R while it is not engaged with the receiving seat 121R, the push latch body 131R engages with the receiving seat 121R. The state in which the push latch body 131R is engaged with the receiving seat 121R is maintained even after the push of the push latch body 131R toward the receiving seat 121R has ended.

[0055] As a result, when the left panel 13L is in an open state and is pushed toward the main body 11, the left panel 13L is closed. The closed state of the left panel 13L is maintained even after the left panel 13L has stopped being pushed toward the main body 11. When the right panel 13R is in an open state and is pushed toward the main body 11, the right panel 13R is closed. The closed state of the right panel 13R is maintained even after the right panel 13R has stopped being pushed toward the main body 11.

[0056] When the push latch body 131L is pressed toward the receiving seat 121L while engaged with the receiving seat 121L, the push latch body 131L will no longer engage with the receiving seat 121L. When the push latch body 131R is pressed toward the receiving seat 121R while engaged with the receiving seat 121R, the push latch body 131R will no longer engage with the receiving seat 121R.

[0057] As a result, when the left panel 13L is closed and pushed toward the main body 11, the left panel 13L is opened. When the right panel 13R is closed and pushed toward the main body 11, the right panel 13R is opened.

[0058] This allows the left panel 13L and the right panel 13R to be easily half-opened. When half-opening the left panel 13L and the right panel 13R, there is no need to pull the left panel 13L and the right panel 13R, respectively. Therefore, the left panel 13L and the right panel 13R can be designed in a way that makes them susceptible to damage when pulled.

[0059] 1.9 Panels 15 and 16 are exploded perspective views schematically illustrating the left panel provided in the blower of the first embodiment. In Fig. 15 and Fig. 16, arrows are drawn indicating the upward, downward, leftward, rightward, forward, and backward directions of the blower.

[0060] As shown in FIGS. 15 and 16, each of the panels 13 included in the left panel 13L and the right panel 13R includes a first panel 141, a nonwoven fabric 142, and a second panel 143.

[0061] The first panel 141, the nonwoven fabric 142, and the second panel 143 are overlapped. The first panel 141 is the outermost side panel. The nonwoven fabric 142 is located inside the first panel 141. The second panel 143 is an inner panel located inside the nonwoven fabric 142. The first panel 141 prevents the nonwoven fabric 142 from standing out. This prevents the first panel 141 from detracting from the design of the air blower 1, and does not restrict the design of the side surface 1S of the air blower 1.

[0062] The first panel 141 and the second panel 143 have a lattice shape. The first panel 141 and the second panel 143 sandwich the nonwoven fabric 142. This allows the first panel 141, the nonwoven fabric 142, and the second panel 143 to pass air through each panel 141. The nonwoven fabric 142 removes dust from the air passing through.

[0063] 15 and 16, the first panel 141 has a first structure 151. The second panel 143 has a second structure 152. The nonwoven fabric 142 has perforations 143a and slits 143b formed therein.

[0064] The first structure 151 protrudes toward the second panel 143 and protrudes toward the second structure 152. The first structure 151 can be engaged with and disengaged from the second structure 152. Therefore, the first structure 151 is detachable from the second structure 152. When the first structure 151 is attached to the second structure 152, the first panel 141 is coupled to the second panel 143. When the first structure 151 is detached from the second structure 152, the first panel 141 is separated from the second panel 143. Therefore, the old nonwoven fabric 142 can be replaced with a new nonwoven fabric. When the old nonwoven fabric 142 is replaced with a new nonwoven fabric, the old nonwoven fabric 142 is disposable. This facilitates maintenance of the air blower 1.

[0065] One of the first structure 151 and the second structure 152 may include a magnet, and the other of the first structure 151 and the second structure 152 may include a magnetic body such as a steel screw. The magnet and the magnetic body attract each other, maintaining the first structure 151 attached to the second structure 152. This allows the first panel 141 to be separated from the second panel 143 by pulling the first panel 141 and the second panel 143 away from each other with a force greater than the force with which the magnet and the magnetic body attract each other. This allows the old nonwoven fabric 142 to be easily replaced with a new nonwoven fabric.

[0066] First structure 151 penetrates through through-section 143a. This makes it possible to prevent nonwoven fabric 142 from moving in the planar direction. Cut 143b extends from through-section 143a. This makes it possible to pass cut 143b through a part of first structure 151 even when an attempt is made to attach nonwoven fabric 142 to first panel 141 and the planar position of first structure 151 is slightly deviated from the planar position of through-section 143a. This makes it possible to easily achieve a state in which first structure 151 penetrates through through-section 143a. This makes it possible to easily attach nonwoven fabric 142 to first panel 141.

[0067] The through portion 143a includes a slit 143c extending from the end surface of the nonwoven fabric 142. The notch 143b includes two slits 143d branching in a Y shape from the tip of the slit 143c.

[0068] The positions and shapes of the through portion 143 a and the notch 143 b are determined according to the positions and shapes of the first structure 151 and the second structure 152 .

Fig. 18 is an enlarged plan view schematically illustrating a nonwoven fabric provided in a blower according to a third modified example of the first embodiment. Fig. 19 is an enlarged plan view schematically illustrating a nonwoven fabric provided in a blower according to the third modified example of the first embodiment.

[0070] 17, in the second modified example of the first embodiment, the through portion 143a includes a slit 143e extending from the end face of the nonwoven fabric 142. The notch 143b includes two slits 143f branching in a T-shape from the tip of the slit 143e.

[0071] 18, in the third modified example of the first embodiment, the through portion 143a includes a rectangular cutout 143g extending from the end face of the nonwoven fabric 142. The notch 143b includes two slits 143h extending from two corners of the rectangular cutout 143g, respectively.

[0072] 19, in the fourth modified example of the first embodiment, the through portion 143a includes a rectangular hole 143i spaced apart from the end face of the nonwoven fabric 142. The notch 143b includes four slits 143j extending from four corners of the rectangular hole 143i, respectively.

[0073] The present disclosure is not limited to the above-described embodiments, and may be replaced with a configuration that is substantially the same as the configuration shown in the above-described embodiments, a configuration that has the same effect, or a configuration that can achieve the same purpose.
