Next, the packing member 200 for packing the air conditioner will be described.

FIG. 3 is a perspective view schematically showing the air conditioner packed by the packing member 200 according to the present embodiment. FIG. 4 is a schematic exploded perspective view of the packing member 200 of FIG. Note that in FIG. 4, the binding band 400 is not shown for simplicity of description.

As shown in FIG. 3, a packing member 200 is arranged on the side of the top panel 1 of the outdoor unit 100 so as to cover the upper surface side of the outdoor unit 100. The structure of the packing member 200 will be described later. Further, on the side of the bottom panel 2 of the outdoor unit 100, the bottom panel 2 is placed, and the bottom protection member 300 in which the legs 9 are housed is arranged. The bottom surface protection member 300 is formed of a packaging material such as cardboard. The packing member 200 and the bottom surface protection member 300 are fixed to the outdoor unit 100 by a binding band 400 wound in the vertical direction. As the binding band 400, for example, a so-called PP band made of polypropylene is used.

The packing member 200 is required to have a function of protecting the air conditioner during storage and transportation of the air conditioner. As shown in FIG. 4, the packing member 200 accommodates, for example, a first cushioning member 500 and a plate member 600.

The first cushioning member 500 directly covers the top panel 1 of the outdoor unit 100 and protects the upper portion of the outdoor unit 100 from a shock or the like due to a load from the upper surface. As the material of the first cushioning member 500, for example, foamed plastic such as Styrofoam is used.

The plate member 600 is arranged on the upper surface of the first cushioning member 500 and is sandwiched between the first cushioning member 500 and the packing member 200. At the distribution stage of the air conditioner, another load may be loaded on the packaging member 200 for the sake of convenience of distribution. Further, when a packaged product of an air conditioner is stored in a warehouse after being shipped from a manufacturing plant of the air conditioner, it is common to stack and store another packaged product on top of the packaged product. Even in such a case, if the plate member 600 is sandwiched between the first cushioning member 500 and the packing member 200, the weight of another load stacked on the packing member 200 is increased by the plate member having a large area. Since it can be supported on the surface of 600, it is possible to prevent the first buffer member 500 from being damaged. Therefore, by sandwiching the plate member 600 between the first cushioning member 500 and the packing member 200, it is possible to avoid a decrease in the protection function of the outdoor unit 100 due to damage to the first cushioning member 500. As the plate material 600, for example, wood such as lauan or cypress is used.

Further, as shown in FIG. 4, the bottom surface protection member 300 has a second cushioning member 320 and an outer frame body 340 that accommodates the second cushioning member 320. The second cushioning member 320 is formed by bending a packaging material such as a corrugated board and has a mounting surface 320a on which the bottom panel 2 and the legs 9 are mounted. The outer frame body 340 accommodates the second cushioning member 320 and is arranged so as to cover the lower surface side of the outdoor unit 100. The outer frame body 340 may be integrally formed of the same packing material as the second cushioning member 320, or may be configured as a separate member.

Next, the structure of the packaging member 200 will be described with reference to FIGS. 5 and 6.

FIG. 5 is a perspective view schematically showing the structure and assembling mode of the lid 210 of the packaging member 200 according to the present embodiment. FIG. 6 is a schematic diagram showing the internal structure of the side wall 214 of the lid 210 of FIG.

As shown in FIGS. 5 and 6, the packing member 200 includes an air conditioner, for example, a lid 210 that covers a part of the outdoor unit 100. The lid 210 is made of a packing material such as corrugated cardboard.

The lid 210 has a plate-like body 212 and an outer wall 214a extending from the edge 212a of the plate-like body 212 in a direction intersecting the plate-like body 212. The lid 210 also has an outer wall 214a and an inner wall 214b that extends with a gap 215 therebetween. The structure of FIG. 5D having the outer wall 214a and the inner wall 214b is referred to as a side wall 214. For example, the plate member 212 can be configured to cover the upper surface of the air conditioner, that is, the top panel 1 of the outdoor unit 100. The outer wall 214a and the inner wall 214b can be configured to cover a part of the side surface of the air conditioner, that is, the outdoor unit 100.

The plate-like body 212, the outer wall 214a, and the inner wall 214b can be formed from a single outer wrapping material 230 as shown in FIG. 5(a). The outer wrapping material 230 can be formed, for example, by punching a packaging material such as a corrugated board using a wooden mold or a metal mold, or by punching. By forming the lid 210 from the single outer packaging material 230, the manufacturing cost of the lid 210 can be reduced.

The outer wall 214a is formed by bending the outer wrapping material 230 in a direction intersecting with the plate-like body 212 from the edge 212a of the plate-like body 212, as shown in, for example, FIGS. .. The inner side wall 214b has the outer packaging material 230 in the direction of the plate-shaped body 212 from the end 214c of the outer wall 214a opposite to the edge 212a of the plate-shaped body 212, for example, as shown by the white block arrow in FIG. It is formed by folding back. Further, the entire outer surface of the outer wall 214a is formed at the same position as the edge 212a of the plate 212 or inside the edge 212a of the plate 212 when the outer surface of the plate 212 is viewed from the front.

For example, as shown in FIG. 5C, the lid 210 includes a first outer wall 214a1 extending in the longitudinal direction and a second outer wall extending in the lateral direction when viewed from the outer surface side of the lid 210. It can be formed to include an outer wall 214a having 214a2. Further, as shown in FIGS. 5A and 5B, the lid 210 can be formed to have a flap 216. The flap 216 is provided, for example, on at least one of the side ends 214a3 of the second outer wall 214a2 in the direction parallel to the edge 212a of the plate-like body 212. The inner wall 214b can be formed by folding the outer wrapping material 230 in the direction of the plate-shaped body 212 from the end 214c of the first outer wall 214a1 opposite to the edge 212a of the plate-shaped body 212. The first outer wall 214a1, the inner wall 214b, and the flap 216 can be joined together by, for example, applying an adhesive or mooring with a stapler.

Further, the lid 210 has a plurality of notches 218a at the boundary 218 between the plate-like body 212 and the outer wall 214a. The notch 218a can be formed, for example, by performing a perforating process on the outer packaging material 230. By fixing the lid 210 to the outdoor unit 100 by the binding band 400 at the position of the notch 218a, it is possible to prevent the boundary 218 of the lid 210 from being eroded by the winding of the binding band 400.

Although the inner wall 214b is provided at a position facing the first outer wall 214a1 in FIG. 5, it may be provided at a position facing the second outer wall 214a2. Further, in FIG. 5, the flap 216 is provided on the side end 214a3 of the second outer wall 214a2, but may be provided on the first outer wall 214a1. Further, in FIG. 5, the plate-shaped body 212, the outer wall 214a, and the inner side wall 214b are assumed to be formed of a single outer packaging material 230, but they are made of separate outer packaging materials 230, and an adhesive is applied or applied. They may be joined together by mooring with a stapler. Further, the outer wall 214a and the inner wall 214b do not have to be directly joined to each other, but may be only indirectly joined via a reinforcing member 250 described later.

The packing member 200 also includes a reinforcing member 250. The reinforcing member 250 is provided inside the side wall 214. In FIG. 5B, the position of the reinforcing member 250 is indicated by a dotted line. As shown in FIG. 5B, the reinforcing member 250 can be arranged, for example, in the space between the two opposing flaps 216 without contacting the flaps 216. By arranging the reinforcing member 250 in the space between the two flaps 216 facing each other, it is possible to prevent the reinforcing member 250 from detaching from both ends in the longitudinal direction of the side wall 214. Further, by making the thickness of the reinforcing member 250 substantially the same as the thickness of the flap 216, the reinforcing member 250 is disposed in the gap 215 between the outer side wall 214a and the inner side wall 214b formed by the flap 216, and the outer side wall 214a. And the inner wall 214b. Further, as shown in FIG. 6, the reinforcing member 250 is arranged in the gap 215 between the outer side wall 214a and the inner side wall 214b. The reinforcing member 250 is sandwiched between the outer wall 214a and the inner wall 214b. In FIG. 6, an end 214c of the outer wall 214a is provided on the lower portion of the reinforcing member 250 to support the reinforcing member 250 from the lower portion. Further, the upper part of the reinforcing member 250 is covered with the plate-like body 212. According to this configuration, since it is not necessary to provide another member for holding the reinforcing member 250, the packaging member 200 can be formed at low cost. Further, according to this configuration, the reinforcing member 250 does not fall off from the lid 210 during transportation, so that the safety of the worker can be ensured.

The reinforcing member 250 may be directly joined to the outer wall 214a and the inner wall 214b by applying an adhesive, for example. By directly joining the reinforcing member 250 to the outer wall 214a and the inner side wall 214b, it is possible to omit sandwiching the flap 216 between the outer wall 214a and the inner side wall 214b in the lid 210. Further, by directly joining the reinforcing member 250 to the outer wall 214a and the inner side wall 214b, it is possible to omit providing the end 214c that directly connects the outer wall 214a and the inner side wall 214b, and the outer wall 214a and the inner side wall 214b can be omitted. Can be formed as a separate packaging material.

As the reinforcing member 250, a material whose strength is less deteriorated by moisture absorption than the lid 210 is used. For example, as the reinforcing member 250, wood such as lauan or cypress is used. Wood is a material such as corrugated board that is less likely to be deteriorated in strength due to moisture absorption. As the wood, for example, plywood such as veneer plywood is used. The air conditioner being transported may be stored under hot and humid conditions in consideration of storage in overseas warehouses due to the globalization of this business. Even under such a condition, by using a material that is less likely to deteriorate in strength due to moisture absorption as the reinforcing member 250 for the packing member 200, it is possible to reduce the deterioration in strength of the packing member 200 of the air conditioner during transportation. .. Therefore, by using as the reinforcing member 250 for the packing member 200 a material that is less likely to deteriorate in strength due to moisture absorption, the possibility of damage or deformation of the packing member 200 due to insufficient strength can be reduced.

Also, since wood is easily obtained and processed, the manufacturing cost of the packaging member 200 can be reduced. Further, since wood can be easily separated as combustible waste, it is friendly to the global environment and the disposal cost can be reduced.

Since the packing member 200 includes the above-described reinforcing member 250, the strength of the outer wall 214a of the lid 210 is improved, and thus the resistance of the binding band 400 from the outside to the inside of the outer wall 214a can be improved. it can. Therefore, according to the reinforcing member 250 described above, it is possible to provide the packing member 200 capable of reducing the damage to the outer wall 214a of the packing member 200 due to the erosion of the binding band 400 and maintaining the appearance of the packing member 200.

As described above, the air conditioner, for example, the outdoor unit 100, has handle portions 150 for the operator to grip the outdoor unit 100 on four sides extending in the height direction when the outdoor unit 100 is transported. ing. However, in the distribution stage of the air conditioner, the carrying work may be performed by gripping the binding band 400. When the binding band 400 is gripped, the packing band 200 is eroded by the weight of the air conditioner, so that the packaging member 200 may be damaged or deformed.

The packaging member 200 intended to protect the product body of the air conditioner may be treated in the same way as the product depending on the transaction target. Such a transaction target is sensitive to wrinkles and breakage of the packing member 200, breakage of cushioning material such as Styrofoam, and even if it is a minute wrinkle or breakage of the packing member 200, a set of products of the air conditioner. May be required to be replaced. The packaging member 200 is discarded after being transported to the installation site of the air conditioner, and the replacement of a set of products becomes a cause of deteriorating the cost effectiveness in the distribution of the air conditioner.

Moreover, damage or deformation of the packaging member 200 may cause damage to the packaged product. Moreover, the product of the air conditioner may drop due to the damage of the packaging member 200, and therefore it is necessary to ensure the safety of the worker.

However, according to the reinforcing member 250 described above, the packaging member 200 capable of maintaining the appearance of the packaging member 200 can be provided, so that it is not necessary to replace the entire air conditioner product set, and the cost in the distribution of the air conditioner is eliminated. It is possible to suppress deterioration of the effect.

Further, according to the above-described reinforcing member 250, damage to the outer side wall 214a of the packaging member 200 can be reduced, so that damage to the packaged product can be suppressed. In addition, the possibility that the product of the air conditioner may fall due to the damage of the packaging member 200 can be suppressed, so that the safety of the worker can be ensured.

Further, in FIG. 5, the lid 210 of the packing member 200 is provided with two sets of an outer wall 214a and an inner wall 214b so as to face each other along the longitudinal direction of the plate-like body 212. it can. Further, in the packing member 200, the reinforcing member 250 can be arranged in the gap 215 between the outer wall 214a and the inner wall 214b of each of the above-mentioned two sets.

When the binding band 400 is gripped in the distribution stage of the air conditioner, the binding band 400 wound around the side wall 214 may be gripped in order to maintain equilibrium during transportation of the air conditioner. Therefore, by arranging the reinforcing member 250 in the gap 215 between the outer wall 214a of the two side walls 214 and the inner side wall 214b described above, the possibility of damage to the outer wall 214a of the packing member 200 due to the erosion of the binding band 400 is increased. It can be reduced. Further, by disposing the reinforcing member 250 in the gap 215 between the outer side wall 214a and the inner side wall 214b of the two side walls 214 described above, the appearance of the packaging member 200 can be maintained for a longer period of time.

FIG. 7 is a schematic enlarged view of a part of the air conditioner packed by the packing member 200 of FIG. In FIG. 7, the packing member 200 is fixed to the outdoor unit 100 by the binding band 400 at the positions of the plurality of notches 218a. As described above, by fixing the lid 210 to the outdoor unit 100 by the binding band 400 at the position of the notch 218a, it is possible to prevent the boundary 218 of the lid 210 from being eroded by the winding of the binding band 400. ..

In FIG. 7, the reinforcing member 250 can be formed so as to be in contact with the surface of the boundary 218 between the plate-shaped body 212 and the outer wall 214a. According to this configuration, since the strength of the boundary 218 that is most easily deformed by the external pressure can be improved, the possibility of damaging the lid 210 can be further reduced, and the appearance of the packaging member 200 can be maintained for a long time.

Consider a case where the packing member 200 does not have the reinforcing member 250 and the binding band 400 is gripped during transportation of the air conditioner in FIG. 7. When the binding band 400 grips and drags the air conditioner in the direction of the white block arrow, the boundary 218 located in the direction opposite to the direction of the white block arrow when viewed from the notch 218a around which the binding band 400 is wound. Area A may wrinkle or break.

However, as shown in FIG. 7, the packaging member 200 can be formed so that the reinforcing member 250 is exposed from the notch 218a. According to this configuration, even when the binding band 400 is gripped during the transportation of the air conditioner, the inward load of the packing member 200 of the binding band 400 is applied to the reinforcing member 250, and the notch 218a. It is not applied to the surrounding boundary 218. Therefore, by exposing the reinforcing member 250 from the notch 218a, it is possible to reduce the possibility that wrinkles or damages may occur in the region A of the boundary 218, so that defective packaging of the air conditioner can be reduced. Further, even if the binding band 400 is gripped, the binding band 400 is in contact with the reinforcing member 250, so that the position of the binding band 400 can be suppressed from moving.

FIG. 8 shows a situation in which a carrier worker 700 holds the corner of the packing member 200 and moves the packed air conditioner packed in the packing member 200 of FIG. 3 in the direction of the arrow. FIG. FIG. 9 is a schematic view of the packing member 200 in the situation of FIG. 8 as viewed from above. In FIG. 8 and FIG. 9, the corners of the packaging member 200 gripped by the transfer operator 700 are indicated by a region B.

In FIG. 8, when the transfer operator 700 grips the area B and moves the air conditioner in the direction of the arrow, the packing member 200 is fixed to the air conditioner with the binding band 400, and thus the packing member 200 of FIG. A load due to the weight of the air conditioner or the like is applied to the position of the dotted line C.

However, as shown in FIG. 7, since the reinforcing member 250 is formed so that the reinforcing member 250 is exposed from the notch 218a, most of the load due to the weight of the air conditioner or the like is applied to the reinforcing member 250. .. Further, even if most of the load due to the weight of the air conditioner is applied to the reinforcing member 250, the reinforcing member 250 is not damaged by the load, and therefore the packaging member 200 is not damaged. Therefore, even if the transport operator 700 grips the corner of the packaging member 200 and transports the packed air conditioner, the packaging member 200 will not be damaged, so that Safety is secured.

In the above-described embodiment, in the packaging member 200, the lid 210 covers a part of the upper surface side of the air conditioner, for example, a part of the top panel 1 side of the outdoor unit 100. Not limited to For example, the outer frame body 340 of the bottom surface protection member 300 may have the same structure as the packaging member 200.

Further, an engaging groove for improving engagement of the binding band 400 may be provided in the portion of the reinforcing member 250 exposed from the cutout 218a in FIG.

Further, in the above-described embodiment, the reinforcing members 250 arranged on the two sets of side walls 214 extending in the longitudinal direction when viewed from the outer surface side of the lid 210 are illustrated, but the present invention is not limited to this. For example, the reinforcing member 250 may be arranged in the gap 215 between the outer wall 214a and the inner side wall 214b extending in the lateral direction when viewed from the outer surface side of the lid 210.

Further, the reinforcing member 250 may be arranged at a place where an external force such as a load due to the binding band 400 may be applied, and the reinforcing member 250 may not be arranged at another place.
