Abstract

PURPOSE: To prevent deformations brought about on the upper face of an outdoor device body, by covering the upper face of the outdoor device body of an airconditioner made of synthetic resin with an upper reinforcing board and packaging them together. CONSTITUTION: A packaging material covering the upper part of an outdoor device body 3 made of synthetic resin is constituted of a cardboard top plate 6 shaped to form a box, a pair of upper buffer materials 5 arranged on the inner right and left sides of the top plate 6 and provided with a U-shaped form and a level difference face 10 inside the U-shape, and a cardboard upper reinforcing board 4 made so as to get in contact with the level difference face 10 of the upper buffer materials 5 at the peripheral part thereof and fix fixing pieces 7 at the front end of a flap 8 extended from the front and rear sides of the middle of the peripheral part, to slits 9 provided in the top plate 6 sides. In this way, the deformations bringing about at the upper face of the outdoor device body 3 can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner packing device, and more particularly to an outdoor unit packing device whose main body is made of plastic.

[0002]

2. Description of the Related Art For packaging an outdoor unit of an air conditioner, for example, a box-shaped bottom plate corrugated cardboard 21 as shown in FIG. 22, an upper shock absorber 24 that covers the upper left and right of the device body 23 to protect the corners from impacts, and a box-shaped top plate 25 that covers the upper shock absorber 24 from above. It is designed to be wound and fastened with a band not attached.

[0003]

By the way, recently, even in outdoor units, there is a growing demand for improvement in appearance and weight reduction, and there is a movement to make the device body 23 plastic.
As a material, there are synthetic resins called AES, AAS, PP and the like. Among them, PP is drawing attention because it is cheaper. However, PP is vulnerable to heat, and when a heat resistant compression test (a test assuming storage in a warehouse for a long period on a hot summer day) is performed with the device body 23 having the shape shown in FIG. 4, The vicinity of the center of the upper end face of the device body 23 may be wavy, which may cause a problem in appearance.
As one means to eliminate this kind of deformation, the upper buffer 2
It is effective to change the shape of 4 from the current U-shape to a box shape covering the entire upper part of the device main body 23. However, foam resin (HPS) is used for this upper buffer 24, and it is left after use. If this is done, it will be an environmental problem, and there is a tendency to reduce the amount used, and if the size of the upper buffer 24 is increased, it will go against the improvement of the environmental problem. Therefore, it is an object of the present invention to provide a packaging device for an air conditioner that can solve the above problems without going against the improvement of environmental problems.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has a box-shaped bottom plate corrugated cardboard and a lower shock absorber that is housed in the bottom plate corrugated cardboard to support the device body. And a cardboard top plate that is formed in a box shape and covers the top of the device body, a pair of upper buffers that are arranged on the left and right inside the top plate, and is provided inside the upper buffer, and the surface is the device. It is composed of an upper reinforcing plate that is brought into contact with the upper surface of the main body.

[0005]

With the above structure, the upper reinforcing plate that covers the upper surface of the device body is held by the upper cushions on the left and right, and the upper cushion is held by the top plate. Thus, even if a heat resistant compression test or the like is performed, the upper surface of the device body and its periphery can be protected, and deformation of the upper surface can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows an outdoor unit of an air conditioner and a packaging device for the outdoor unit. Reference numeral 1 denotes a box-shaped bottom plate corrugated cardboard, 2 denotes a foamed resin lower cushion disposed on the left and right inside the bottom plate corrugated cardboard 1, 3 is an outdoor unit whose main body is made of synthetic resin, 4 is a peculiar to this embodiment, and is an upper reinforcing plate made of cardboard that is placed on the upper surface of the outdoor unit 3 and 5 is placed on the upper reinforcing plate 4 to cover the outdoor unit 3. An upper shock absorber made of foam resin that protects the right and left corners of the upper part from impacts and the like, and 6 is a box-shaped top plate that covers the upper shock absorber 5 from above, and is made of cardboard.
A flap 8 having a locking piece 7 at its tip is provided in the front-rear center of the upper reinforcing plate 4. On the other hand, slits 9 through which the above-mentioned locking pieces 7 are inserted and locked are provided at the front and rear central corners of the top plate 6. Further, inside the upper shock absorber 5, stepped surfaces 10 are provided which are aligned with the upper left and right corners of the outdoor unit 3.

FIG. 2 shows an assembly of the top plate 6, the upper cushioning member 5, and the upper reinforcing plate 4 which is carried out when the outdoor unit 3 is packed. The work is performed on the top plate 6 as shown in FIG. After arranging the upper shock absorbers 5 on the left and right sides with the inside facing upwards, the upper reinforcing plate 4 is turned upside down to the step surface 10 of the upper shock absorbers 5 and the locking provided at the tip of the flap 8 is performed. The piece 7 is inserted into the slit 9 of the top plate 6 to obtain the state shown in FIG. This is because the outdoor unit 3 can be easily covered in such a state. FIG. 3 is a partial cross-sectional view showing the packed state of the outdoor unit, and it can be seen that the upper surface of the outdoor unit 3 is pressed by the upper reinforcing plate 4. A band 11 is wound and fastened on the outside of the packing device including the bottom cardboard 1, the top plate 6 and the like.

[0008]

According to the packing apparatus described above, the upper surface of the main body of the outdoor unit, which is the object to be packed, is reinforced by the upper reinforcing plate, so that even if the main body is made of synthetic resin, it is deformed during storage. Also, it is possible to make the upper shock absorber thinner by providing the upper reinforcing plate, so it helps prevent environmental damage to some extent, and when packing, the top plate and the upper shock absorber are used. Since the upper reinforcing plate and the upper reinforcing plate are integrated to cover the packaged object, the packing work can be performed easily and the work efficiency is improved.
