[0003] [[Patent Document 1]] Japanese Unexamined Patent Publication No. 10-167374 [[Summary of the Invention]] [[Problems to be Solved by the Invention]]

[0004] In the conventional packaging device for a ventilation device disclosed in Patent Document 1, the front surface of the grill is protected by the grill holder. However, the back surface of the grill is exposed except for the portion where the wrap-around buffer structure of the grill holder is disposed. Therefore, depending on the positional relationship between the main body and the grill in the outer box, the main body may interfere with the exposed portion of the back surface of the grill. As a result, when the outer box storing the main body and the grill is transported, the main body may interfere with the grill and cause damage to the grill.

[0005] The present disclosure solves the problems described above, and an object of the present disclosure is to provide a packaging device for a blower device that can more reliably prevent interference of a blower device main body with a decorative panel. [[Means for Solving the Problems]]

[0006] The packaging device for a blower according to this disclosure comprises a panel protection member that covers a decorative panel that is detachable from a blower body having the function of generating airflow when the decorative panel is removed from the blower body, and an outer box that houses the blower body and the decorative panel with the panel protection member covering the decorative panel. The panel protection member is made of a cushioning plate material, and the outer box houses the blower body and the decorative panel with a specific surface formed on the blower body facing the decorative panel. The blower body is provided with a protrusion that protrudes from the specific surface, and the panel protection member has an intervening portion for the protrusion, which is interposed between the protrusion and the decorative panel when the blower body and the decorative panel are housed in the outer box. [Effects of the Invention]

[0007] According to this disclosure, interference between the blower body and the decorative panel can be more reliably prevented. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0009] The embodiments for carrying out the subject matter of this disclosure will be described with reference to the attached figures. In each figure, the same or corresponding parts are denoted by the same reference numerals, and redundant explanations are simplified or omitted as appropriate. The subject matter of this disclosure is not limited to the following embodiments, and any modification of any component of the embodiments or omission of any component of the embodiments is possible without departing from the spirit of this disclosure.

[0010] Embodiment 1. Figure 1 is a perspective view showing a packaging device for a blower according to Embodiment 1. Figure 2 is a cross-sectional view showing the duct fan in Figure 1 being packaged by the blower packaging device. In the figure, in this embodiment, the blower being packaged by the blower packaging device 1 is a duct fan 2. The duct fan 2 is a blower that draws in air from inside a room and discharges it to the outside through a ventilation duct. Hereinafter, the blower packaging device 1 will simply be referred to as "packaging device 1".

[0011] The duct ventilation fan 2 comprises a blower unit 21 and a decorative panel 22. The blower unit 21 has the function of generating airflow and is installed, for example, on a ceiling panel located in the upper part of a room. The decorative panel 22 is attached to the blower unit 21 in an exposed state in the room. The decorative panel 22 is detachable from the blower unit 21.

[0012] For example, when the duct ventilation fan 2 is being transported, the blower unit 21 and the decorative panel 22 are packaged by the packaging device 1. The blower unit 21 and the decorative panel 22 are packaged by the packaging device 1 with the decorative panel 22 removed from the blower unit 21.

[0013] The blower unit 21 comprises a housing 23, a blower 24, and a duct connecting component 25. The blower 24 and the duct connecting component 25 are attached to the housing 23.

[0014] A rectangular opening, formed by the side walls of the enclosure 23, is provided on the underside of the enclosure 23. The enclosure 23 is attached to the ceiling panel by being inserted into a recessed hole formed in the ceiling panel. The enclosure 23 is attached to the ceiling panel with the enclosure opening facing downwards into the room. This makes it possible to perform maintenance such as construction, inspection, and cleaning of the inside of the enclosure 23 from inside the room through the enclosure opening.

[0015] The housing 23 is provided with a flange 231 that extends outward from the side of the housing 23 along the bottom surface of the housing 23, around its entire circumference. The flange 231 is provided with multiple mounting holes. The housing 23 is attached to the ceiling panel by fasteners passed through each of the mounting holes in the flange 231.

[0016] The duct connector 25 is attached to the side of the housing 23. The housing 23 is provided with a pair of protrusions 211 for attaching the duct connector 25 to the housing 23. The pair of protrusions 211 project outwards from the upper surface 21a of the housing 23. The upper surface 21a of the housing 23 is a specific surface formed on the blower body 21. The pair of protrusions 211 are provided at the ends of the upper surface 21a of the housing 23 on the side of the duct connector 25.

[0017] The duct connector 25 has a main pipe section 251, a mounting section 252, and a connecting section 253. The mounting section 252 is provided at one end of the main pipe section 251. The mounting section 252 has a rectangular shape that protrudes outward from the outer circumference of one end of the main pipe section 251. The connecting section 253 is provided at the other end of the main pipe section 251. The connecting section 253 has a cylindrical shape that protrudes from the other end of the main pipe section 251. As a result, the cross-sectional shape of the main pipe section 251 changes continuously from rectangular to circular from the mounting section 252 to the connecting section 253.

[0018] As shown in Figure 1, a pair of insertion holes 254 is provided on the edge of the mounting portion 252 of the duct connection component 25. The duct connection component 25 is attached to the side surface of the housing 23 in a state where the pair of projecting portions 211 are inserted into the pair of insertion holes 254 and the mounting portion 252 is hooked onto the pair of projecting portions 211. Accordingly, the duct connection component 25 is detachably attached to the side surface of the housing 23. In the state where the duct connection component 25 is attached to the side surface of the housing 23, the tip end of each projecting portion 211 protrudes outward from the edge of the mounting portion 252.

[0019] Here, Figure 3 is a schematic perspective view showing a state where the duct connection component 25 in Figure 1 is removed from the housing 23. The duct connection component 25 is attached to the housing 23 in a state of covering the discharge port 232 formed on the side surface of the housing 23. In a state where the blower main body 21 is attached to the ceiling plate, the ventilation duct 3 leading to the outdoors is connected to the connection portion 253 of the duct connection component 25. The ventilation duct 3 is connected to a duct hood or the like provided on the outer wall of a building.

[0020] As shown in Figure 1, a blower opening 233 formed to match the shape of a part of the blower 24 is provided on the upper surface 21a of the housing 23. The blower 24 includes an electric motor 241 and a fan (not shown). The electric motor 241 is attached to the housing 23 in a state of being passed through the blower opening 233. Accordingly, a part of the electric motor 241 protrudes from the upper surface 21a of the housing 23 to the outside of the housing 23 as a blower exposed portion 241a. Therefore, the blower exposed portion 241a protrudes from the upper surface 21a of the housing 23 toward the same side as each of the projecting portions 211. The electric motor 241 generates driving force for rotating the fan when power is supplied to the electric motor 241.

[0021] The fan of the blower 24 is attached to the electric motor 241 inside the housing 23. The fan is rotated by the electric motor 241 to generate an airflow inside the housing 23. For example, a centrifugal fan is used as the fan.

[0022] A fan casing (not shown) is provided inside the housing 23. The fan casing has an intake port. The fan casing is positioned inside the housing 23 with the intake port facing the housing opening of the housing 23. Inside the housing 23, an internal air passage is formed by the fan casing, connecting the intake port to the discharge port 232. The fan of the blower 24 is positioned in the internal air passage formed by the fan casing.

[0023] With the blower unit 21 attached to the ceiling panel, the airflow generated by the rotation of the fan of the blower 24 flows from the room through the opening of the housing 23 to the intake port of the fan casing. The airflow that flows into the intake port of the fan casing flows through the internal air passage inside the housing 23, passes through the discharge port 232, and is then discharged to the outside through the duct connection part 25 and the ventilation duct 3.

[0024] As shown in Figure 2, the decorative panel 22 has a decorative surface 22a as the first surface and a back surface 22b as the second surface. The decorative surface 22a and the back surface 22b are surfaces that face opposite each other in the thickness direction of the decorative panel 22. In this embodiment, the shape of the decorative panel 22 when viewed along the thickness direction of the decorative panel 22 is rectangular.

[0025] A panel edge is formed around the entire circumference of the decorative panel 22. The panel edge is a wall portion that protrudes from the back surface 22b along the thickness direction of the decorative panel 22. As a result, a recess is formed on the inside of the panel edge of the decorative panel 22, with the back surface 22b as the bottom surface. In the decorative panel 22, the outer surface of the panel edge becomes the side surface of the decorative panel 22.

[0026] A spring (not shown) is attached to the back surface 22b of the decorative panel 22. A spring mounting part (not shown) is fixed to the inner surface of the housing 23, located at the housing opening. When the blower unit 21 is attached to the ceiling panel, the decorative panel 22 is attached to the housing 23 with its back surface 22b facing the housing opening by attaching the spring to the spring mounting part. This allows the decorative panel 22 to be detachably attached to the blower unit 21.

[0027] The decorative panel 22 is provided with multiple ventilation holes 221 formed in a mesh pattern. When the decorative panel 22 is attached to the blower unit body 21, when airflow is generated by the rotation of the fan of the blower 24, the airflow flows from the room through the multiple ventilation holes 221 of the decorative panel 22 and into the intake port of the housing 23.

[0028] The packaging device 1, used when transporting the duct ventilation fan 2, has an outer box 11 and a panel protection member 12.

[0029] The panel protection member 12 covers the decorative panel 22 when it is removed from the blower unit body 21. The outer casing 11 houses the blower unit body 21 and the decorative panel 22 with the panel protection member 12 covering the decorative panel 22.

[0030] The outer box 11 is constructed of cushioning material that has a shock-absorbing function. Examples of cushioning material used to make up the outer box 11 include corrugated cardboard, plastic corrugated cardboard, wood, and polystyrene foam. The outer box 11 has a box body 111 and four lid flaps 112.

[0031] The box body 111 has a rectangular box opening 111a. The shape of the box body 111 is a rectangular parallelepiped, with the top surface forming the box opening 111a, out of the bottom surface, top surface, and four side surfaces. The box opening 111a is formed by being surrounded by the upper edges of the four side surfaces.

[0032] The lid flaps 112 are connected to the upper edges of each of the four side panels. The box opening 111a is closed by folding each lid flap 112 inward relative to the box body 111, and opened by folding each lid flap 112 outward relative to the box body 111.

[0033] As shown in Figure 2, the blower unit 21 is housed in the box body 111 with the upper surface 21a of the housing 23 facing the box opening 111a and the lower surface of the housing 23 facing the bottom surface of the box body 111. As a result, when the blower unit 21 is housed in the box body 111, the lower surface of the housing 23 overlaps with the bottom surface of the box body 111. Since the lower surface of the housing 23 follows the shape of a plane, the blower unit 21 is stably housed in the box body 111. When the blower unit 21 is housed in the box body 111, the blower exposed portion 241a and the pair of protruding portions 211 of the blower unit 21 protrude from the upper surface 21a of the housing 23 toward the box opening 111a.

[0034] The decorative panel 22 is placed on the blower unit 21 and housed together with the blower unit 21 in the box body 111. As a result, the box body 111 of the outer box 11 houses the blower unit 21 and the decorative panel 22 with the upper surface 21a of the housing 23 facing the decorative panel 22. Therefore, when the box body 111 houses the blower unit 21 and the decorative panel 22, the blower exposed portion 24a and the pair of protruding portions 211 protrude from the upper surface 21a of the housing 23 toward the decorative panel 22.

[0035] The decorative panel 22 is housed in the box body 111 while covered by the panel protection member 12. The panel protection member 12 is made of a cushioning plate material that has a shock-absorbing function. Examples of cushioning plate materials that make up the panel protection member 12 include corrugated cardboard, plastic corrugated cardboard, wood, and polystyrene foam.

[0036] Figure 4 is a perspective view showing the panel protection member 12 of Figure 1. The panel protection member 12 has a first surface protection portion 121, a pair of side protection portions 122, and a pair of second surface protection portions 123.

[0037] The first protective portion 121 covers the decorative surface 22a of the decorative panel 22. The shape of the first protective portion 121 is such that it covers the entire decorative surface 22a of the decorative panel 22. In this embodiment, the shape of the first protective portion 121 is rectangular.

[0038] A pair of side protection sections 122 are connected to the first surface protection section 121. Each side protection section 122 is connected to each of the widthwise ends of the first surface protection section 121. The shape of the pair of side protection sections 122 is rectangular, following the widthwise ends of the first surface protection section 121. The pair of side protection sections 122 are bent relative to the first surface protection section 121 so that they face each other via the decorative panel 22 in the widthwise direction of the first surface protection section 121. The pair of side protection sections 122 individually cover two of the four sides of the decorative panel 22 that face each other.

[0039] The pair of second surface protection sections 123 are individually connected to the pair of side protection sections 122. Each of the second surface protection sections 123 is bent relative to the side protection section 122 in the thickness direction of the decorative panel 22 so as to sandwich the decorative panel 22 between itself and the first surface protection section 121. The pair of second surface protection sections 123 extend toward each other from the pair of side protection sections 122.

[0040] Each of the pair of second protective sections 123 covers the back surface 22b of the decorative panel 22. In this embodiment, each second protective section 123 covers different areas of the back surface 22b of the decorative panel 22.

[0041] Each of the pair of second surface protection parts 123 has a second surface protection part main body 131 and a protruding part intervening part 132.

[0042] Each second-side protective body 131 is individually connected to each side protective body 122. Each second-side protective body 131 covers the back surface 22b of the decorative panel 22 while being separated from the back surface 22b of the decorative panel 22.

[0043] Each second surface protection body 131 has a first restricting space 125 formed at its end. In this embodiment, the shape of the first restricting space 125 is a rectangular slit extending from the end of the second surface protection body 131 toward the side protection 122. Each second surface protection body 131 has a pair of opposing parts 123a that face each other across the first restricting space 125.

[0044] The size of each first restricting space 125 formed in each second protective body 131 is such that each protrusion 211 can be inserted. The position of each first restricting space 125 formed in each second protective body 131 is such that each protrusion 211 is positioned when the blower body 21 and the decorative panel 22 are housed in the box body 111 of the outer box 11.

[0045] A pair of second surface protection sections 123 have a second restricted space section 126 formed within them. The blower exposed section 241a can be inserted into the second restricted space section 126. The shape of the second restricted space section 126 matches the shape of the blower exposed section 241a. In this embodiment, a portion of the second restricted space section 126 is formed at the end of one of the second surface protection section main body sections 131, and the remaining portion of the second restricted space section 126 is formed at the end of the other second surface protection section main body section 131. The position of the second restricted space section 126 formed in the pair of second surface protection sections 123 is such that the blower exposed section 241a is positioned when the blower body 21 and decorative panel 22 are housed in the box body 111 of the outer box 11.

[0046] In each of the pair of second surface protection sections 123, a protruding section intervening section 132 is connected to the main body section 131 of the second surface protection section. In each second surface protection section 123, the protruding section intervening section 132 is connected to the portion of the main body section 131 of the second surface protection section that forms the end of the first regulated space section 125.

[0047] Each intervening portion 132 for protruding parts is positioned between a pair of opposing portions 123a, that is, it is bendable from the first regulated space portion 125 toward the back surface 22b of the decorative panel 22 relative to the second surface protection body portion 131. In the panel protection member 12, each intervening portion 132 for protruding parts is bent toward the back surface 22b of the decorative panel 22 relative to the second surface protection body portion 131, causing each intervening portion 132 to recede relative to the second surface protection body portion 131. As shown in Figure 2, the position of each intervening portion 132 for protruding parts is such that it is interposed between each protruding portion 211 of the blower body 21 and the decorative panel 22 when the decorative panel 22 is housed in the box body 111 of the outer box 11.

[0048] When the blower unit body 21 and the decorative panel 22 are housed in the box body 111 of the outer casing 11, the second surface protection parts 123 are positioned between the blower unit body 21 and the decorative panel 22, as shown in Figure 2.

[0049] When the blower unit body 21 and the decorative panel 22 are housed in the box body 111, each protruding part intervening portion 132 is bent toward the back surface 22b of the decorative panel 22, so that each protruding part 211 is inserted into each first restricted space portion 125, and each protruding part intervening portion 132 is interposed between each protruding part 211 and the decorative panel 22. Also, when the blower unit body 21 and the decorative panel 22 are housed in the box body 111, the blower exposed portion 241a is inserted into the second restricted space portion 126.

[0050] Figure 5 is an unfolded view showing the panel protection member 12 of Figure 4 in its unfolded state. The panel protection member 12 is formed by folding a single panel protection buffer plate material 120. The panel protection buffer plate material 120 is a buffer plate material that has the same shape as the panel protection member 12 when it is unfolded. Therefore, in the panel protection buffer plate material 120, the second surface protection portion 123 is connected to each of the widthwise ends of the first surface protection portion 121 via the side protection portion 122.

[0051] Each second protective surface portion 123 of the panel protective buffer plate material 120 has a pair of notches 127 formed therein. In each second protective surface portion 123, the pair of notches 127 separates the intervening portion 132 for the protruding part and the pair of opposing parts 123a.

[0052] The panel protection buffer plate material 120 has a boundary line 120a between the first surface protection portion 121 and the side protection portion 122, and a boundary line 120b between the side protection portion 122 and the second surface protection portion 123. The panel protection buffer plate material 120 covers the decorative panel 22 by folding along the boundary lines 120a and 120b with the decorative panel 22 facing inward when the decorative surface 22a of the decorative panel 22 is superimposed on the first surface protection portion 121. The panel protection buffer plate material 120 is formed as a panel protection member 12 by covering the decorative panel 22.

[0053] Figure 6 is a perspective view showing the panel protection member 12 in a state where each of the intervening portions 132 for the protruding parts 132 in Figure 5 is not bent relative to each of the main body portions 131 of the second surface protection part. When each of the intervening portions 132 for the protruding parts 132 is not bent relative to each of the main body portions 131 of the second surface protection part, each intervening portion 132 for the protruding parts 132 is located on the same plane as each of the main body portions 131 of the second surface protection part, and the intervening portion 132 for the protruding parts 132 is located in the first restricting space portion 125. The state of the panel protection member 12 is such that, as shown in Figure 4, the intervening portion 132 for the protruding parts 132 is recessed relative to the main body portion 131 of the second surface protection part, as the intervening portion 132 for the protruding parts 132 is bent from the first restricting space portion 125 toward the back surface 22b of the decorative panel 22 toward the main body portion 131 of the second surface protection part.

[0054] Next, the procedure for packaging the duct ventilation fan 2 using the packaging device 1 will be described. The duct ventilation fan 2 is packaged by placing the blower unit body 21 and the decorative panel 22 into the box body 111 of the outer box 11, with the decorative panel 22 removed from the blower unit body 21.

[0055] When housing the blower unit 21 and decorative panel 22 in the box body 111 of the outer casing 11, the blower unit 21 is first housed in the box body 111. When housing the blower unit 21 in the box body 111, the upper surface 21a of the housing 23 is facing upward and the lower surface of the housing 23 is facing downward, and the blower unit 21 is inserted into the box body 111 through the box opening 111a. As a result, the blower unit 21 is housed in the box body 111 with the blower exposed portion 241a and the pair of protruding portions 211 protruding upward from the upper surface 21a of the housing 23.

[0056] After housing the blower unit 21 in the box body 111, the decorative panel 22 is then housed in the box body 111. When housing the decorative panel 22 in the box body 111, the decorative panel 22 is covered with the panel protection member 12 before it is placed in the box body 111.

[0057] When covering the decorative panel 22 with the panel protection member 12, a single panel protection buffer plate material 120 is folded while covering the decorative panel 22. At this time, the decorative surface 22a of the decorative panel 22 is covered by the first surface protection portion 121, the two sides of the decorative panel 22 are covered by a pair of side protection portions 122, and the back surface 22b of the decorative panel 22 is covered by a pair of second surface protection portions 123. As a result, as shown in Figure 6, the panel protection member 12 is formed in a state where each protruding portion intervening portion 132 is not folded relative to each second surface protection portion main body portion 131.

[0058] Next, each intervening portion 132 for protruding parts facing the back surface 22b of the decorative panel 22 is bent toward the back surface 22b of the decorative panel 22. As a result, as shown in Figure 4, a panel protection member 12 is formed in which each intervening portion 132 for protruding parts is recessed toward the back surface 22b of the decorative panel 22 relative to each second surface protection main body 131.

[0059] Next, the decorative panel 22, covered by the panel protection member 12, is inserted into the box body 111 through the box opening 111a. At this time, the decorative panel 22 is placed into the box body 111 with its back surface 22b facing the blower body 21. Also, at this time, the decorative panel 22 is placed on the blower body 21 while aligning the position of each first restrictive space 125 with the position of each protrusion 211 and aligning the position of the second restrictive space 126 with the position of the blower exposed part 241a. As a result, each protrusion 211 is inserted into each first restrictive space 125, and the blower exposed part 241a is inserted into the second restrictive space 126. In addition, each protrusion intervening part 132 is interposed between the back surface 22b of the decorative panel 22 and each protrusion 211. In this way, the decorative panel 22 is housed in the box body 111.

[0060] After this, the packaging of the duct ventilation fan 2 by the packaging device 1 is completed by folding each lid flap 112 to close the box opening 111a.

[0061] In this type of packaging device 1, the panel protection member 12 covers the decorative panel 22 when the decorative panel 22 is removed from the blower body 21. The outer box 11 houses the blower body 21 and the decorative panel 22 with the upper surface 21a of the housing 23, which is a specific surface formed on the blower body 21, facing the decorative panel 22. The blower body 21 is provided with a pair of protrusions 211 that protrude from the upper surface 21a of the housing 23. The panel protection member 12 has a pair of intervening parts 132 for the protrusions. Each intervening part 132 for the protrusions is interposed between each of the pair of protrusions 211 and the decorative panel 22 when the blower body 21 and the decorative panel 22 are housed in the outer box 11.

[0062] Therefore, when the blower body 21 and decorative panel 22 are housed in the outer box 11, the intervening parts 132 for each protrusion 211 of the blower body 21 can prevent interference with the decorative panel 22. This makes it possible to more reliably prevent interference between the blower body 21 and the decorative panel 22. Consequently, even if the packaged product, which is packaged with the blower body 21 and decorative panel 22 by the packaging device 1, is vibrated during transport or is accidentally dropped and subjected to impact, it is possible to prevent the blower body 21 from colliding with the decorative panel 22. This makes it possible to more reliably prevent damage to the decorative panel 22.

[0063] Furthermore, in the panel protection member 12, the intervening portion 132 for protruding parts in each second surface protection portion 123 that covers the back surface 22b of the decorative panel 22 is connected to the main body portion 131 of the second surface protection portion. Each intervening portion 132 for protruding parts is bendable toward the back surface 22b of the decorative panel 22 relative to the main body portion 131 of the second surface protection portion. Therefore, the position of the intervening portion 132 for protruding parts can be set closer to the decorative panel 22 than the position of the main body portion 131 of the second surface protection portion. As a result, when the blower body 21 and the decorative panel 22 are housed in the outer casing 11, the tips of each protruding part 211 can be positioned closer to the decorative panel 22 than the position of the main body portion 131 of the second surface protection portion. Consequently, the decorative panel 22 can be housed in the outer casing 11 closer to the blower body 21 than if each intervening portion 132 for protruding parts were not bendable toward the main body portion 131 of the second surface protection portion. This allows for a reduction in the size of the outer box 11, thereby reducing the amount of material used for the outer box 11. Furthermore, because the outer box 11 can be reduced in size, the number of packaged products that can be loaded can be increased when the packaged products, which consist of the blower unit 21 and decorative panel 22, are packaged by the packaging device 1, are transported by vehicle. This is expected to reduce the transportation costs of the packaged products.

[0064] Furthermore, a first restricting space 125 is formed in the main body 131 of the second protective section. The intervening portion 132 for the protruding portion is bendable from the first restricting space 125 toward the back surface 22b of the decorative panel 22 relative to the main body 131 of the second protective section. By bending the intervening portion 132 for the protruding portion toward the back surface 22b of the decorative panel 22 relative to the main body 131 of the second protective section, the protruding portion 211 can be inserted into the first restricting space 125. As a result, the blower body 21 and the decorative panel 22 can be housed in the outer casing 11 with the protruding portion 211 inserted into the first restricting space 125. This restricts the position of the protruding portion 211 within the first restricting space 125, and prevents the position of the panel protection member 12 from shifting relative to the blower body 21. Therefore, the intervening portion 132 for the protruding portion can be more reliably maintained between the protruding portion 211 and the decorative panel 22 inside the outer box 11, and interference of the blower body 21 with the decorative panel 22 can be more reliably prevented.

[0065] Furthermore, a portion of the blower 24 protrudes from the upper surface 21a of the housing 23 as a blower exposed portion 241a. A second restrictive space 126 is formed in the panel protection member 12. When the blower body 21 and the decorative panel 22 are housed in the outer casing 11, the blower exposed portion 241a is inserted into the second restrictive space 126. Therefore, when the blower body 21 and the decorative panel 22 are housed in the outer casing 11, interference between the blower exposed portion 241a and the panel protection member 12 can be avoided. As a result, the decorative panel 22 can be housed in the outer casing 11 closer to the blower exposed portion 241a than when the second restrictive space 126 is not formed in the panel protection member 12. Thus, the outer casing 11 can be further reduced in size. In addition, the position of the blower exposed portion 241a can be restricted to within the second restrictive space 126, and the position of the panel protection member 12 cannot be shifted relative to the blower body 21. This makes it possible to more reliably maintain the state in which the intervening portion 132 for the protruding portion is interposed between the protruding portion 211 and the decorative panel 22 inside the outer box 11, and to more reliably prevent interference of the blower body 21 with the decorative panel 22.

[0066] In the above embodiment, one intervening portion 132 for protruding portions is connected to one main body portion 131 of the second surface protection member 12. However, if there are other protruding portions in addition to the pair of protruding portions 211 that protrude from the upper surface 21a of the housing 23, the number of intervening portions 132 for protruding portions connected to one main body portion 131 of the second surface protection member may be multiple. In this case, the position of each intervening portion 132 for protruding portions is determined in accordance with the positions of the pair of protruding portions 211 and the other protruding portions.

[0067] Furthermore, in the above embodiment, the panel protection member 12 has a pair of second surface protection parts 123. However, the number of second surface protection parts 123 in the panel protection member 12 may be reduced to one, and the single second surface protection part 123 may cover all or part of the back surface 22b of the decorative panel 22. In this case, the second surface protection part 123 is connected to only one of the pair of side surface protection parts 122. In this case, the second surface protection part 123 may have a pair of first restricting space parts 125 formed in the second surface protection part main body 131 to match the respective positions of the pair of protrusions 211, and a pair of intervening parts 132 for protrusions corresponding to each first restricting space part 125 may be connected to the second surface protection part main body 131. In this case, each intervening part 132 for protrusions is bendable relative to the second surface protection part main body 131 from the first restricting space part 125 toward the back surface 22b of the decorative panel 22.

[0068] Furthermore, if the number of second surface protection portions 123 in the panel protection member 12 is set to one, one first restricting space portion 125 may be formed in the second surface protection portion main body portion 131 in the region including the positions of each of the pair of protrusions 211. In this case, a pair of intervening portions 132 for protrusions, each individually interposed between each of the pair of protrusions 211 and the decorative panel 22, may be connected to the second surface protection portion main body portion 131, or a single intervening portion 132 for protrusions, collectively interposed between the pair of protrusions 211 and the decorative panel 22, may be connected to the second surface protection portion main body portion 131. In this case as well, the intervening portions 132 for protrusions are bendable relative to the second surface protection portion main body portion 131 from the first restricting space portion 125 toward the back surface 22b of the decorative panel 22.

[0069] Furthermore, in the above embodiment, the intervening portion 132 for the protruding portion is bent toward the back surface 22b of the decorative panel 22 relative to the main body portion 131 of the second surface protection portion, thereby enabling the protruding portion 211 to be inserted into the first regulated space portion 125. However, by making the length of the intervening portion 132 for the protruding portion longer than the dimensions of the first regulated space portion 125, the intervening portion 132 for the protruding portion may be interposed between the protruding portion 211 and the decorative panel 22 at a position outside the first regulated space portion 125. Even in this case, interference of the blower body 21 with the decorative panel 22 can be prevented by the intervening portion 132 for the protruding portion.

[0070] Furthermore, in the above embodiment, a duct fan 2 is used as the blower that is packaged by the packaging device 1. However, the blower that is packaged by the packaging device 1 is not limited to a duct fan 2, but can be any blower that has the function of generating airflow and from which a decorative panel can be removed. For example, a fan other than a duct fan 2, an air conditioning unit, etc., may be used as the blower that is packaged by the packaging device 1.
