Embodiment 1

(9) FIG. 1 is a perspective view showing the installation state of an air conditioner according to Embodiment 1 of the present invention. In this embodiment, as a representative example of the air conditioner, a ceiling-embedded, four-way cassette-type indoor unit 1, which can be embedded in an indoor ceiling and has air outlets in four directions, will be described. The indoor unit 1 is connected with an outdoor unit (not shown) through a refrigerant pipe to form a refrigerant circuit through which a refrigerant is circulated for refrigeration, air conditioning, etc. Here, the air conditioner which is separated into the indoor unit 1 and the outdoor unit will be described, but the air conditioner may be an integral type. In addition, while the air conditioner will be described here, the term air conditioner in the present invention also includes ventilation devices and refrigerating devices.

(10) As shown in FIG. 1, the indoor unit 1 of this embodiment has a box-shaped unit main body 2 having a top panel and a side panel, and an opening part directed toward an indoor space (air-conditioned space). Hanging clamps 5 are mounted at the four corners on the outside of the unit main body 2 of this embodiment. On the other hand, four hanging bolts 7 are suspended from a beam etc. and the indoor unit 1 is fixed and installed by fastening the hanging clamps 5 at arbitrary positions of the hanging bolts 7.

(11) The unit main body 2 houses an indoor blower fan (not shown), an indoor unit heat exchanger which exchanges the heat of indoor air, etc. A decorative panel 3 having a substantially quadrangular shape in planar view, which serves as a design surface (exterior surface) of the indoor unit 1, is mounted on the lower side of the indoor unit 1 and faces the indoor space. Near the center of the decorative panel 3, a suction grille, which serves as a suction port of air into the indoor unit 1, is provided along with a dust removal filter. On each side of the decorative panel 3, an air outlet is formed along each side of the decorative panel 3. Each air outlet is provided with an airflow directing vane 4.

(12) FIGS. 2A and 2B are views illustrating the packing material according to Embodiment 1 of the present invention. The packing material packs the indoor unit 1. FIG. 2A is a view showing the relation between the unit main body 2 and the packing material. The packing material for an air conditioner has an upper cover 11, a body part cover 12, and a lower cover 13, made of cardboard. The upper cover 11 serves as a lid of the packing material and covers the upper surface of the unit main body 2. In this embodiment, the upper cover 11 is utilized as a protective sheet. In order to prevent misalignment with the body part cover 12, the upper cover 11 of this embodiment is bent at the edges (four sides) nearly at a right angle and formed into a box shape. The body part cover 12 serves as a body part of the packing material and covers the side surface of the unit main body 2. The lower cover 13 serves as a bottom part of the packing material, and covers the lower surface of the unit main body 2 and holds the unit main body 2.

(13) FIG. 2B is a view showing the packing material with the unit main body 2 packed therein. As shown in FIG. 2B, a border is printed on the upper cover 11 which matches the outline of the lower surface part of the unit main body 2. For example, this upper cover 11 serves as a paper pattern for positioning when a hole is bored in the installed ceiling to thereby expose the unit main body 2 indoors. Other than this border, a brand name, type name, unpacking procedure, cautions, method of use, etc. are printed on the upper cover 11. Especially in this embodiment, a cutoff line etc., which serves as a cut and bent up part 11a and a slit part 11b, is printed on the upper cover 11. In view of utilizing the upper cover 11 as a protective sheet for covering the opening part of the unit main body 2, it is desirable that an ink (paint) containing a material having a static electricity removing property (an antistatic material), such as a substance containing gallium, is used for printing on the upper cover 11, although the present invention is not particularly limited to this example.

(14) FIG. 3 is a view illustrating the upper cover 11 when utilized as a protective sheet according to Embodiment 1 of the present invention. When the upper cover 11 is utilized as a protective sheet for keeping out dust etc., an incision is made with a knife etc. into the cut and bent up part 11a to cut and bend it up nearly at a right angle. The slit part 11b is formed in the cut and bent up part 11a, and the hanging clamp 5 of the unit main body 2 is inserted into this slit part 11b. Here, the cut and bent up part 11a is formed so that the insertion direction of the hanging clamp 5 and the bent-up surface intersect orthogonally with each other. In order to secure the length of the slit part 11b without making an incision at the edge of the upper cover 11, part of the sides of the cut and bent up part 11a is inclined. When utilized as a protective sheet, the cover part 11c covers the opening part of the unit main body 2 to keep out dust etc., and the cover part 11c corresponds to the area surrounded by the cut and bent up parts 11a.

(15) The upper cover 11 can be fixed on the unit main body 2 and the opening part of the unit main body 2 can be covered with the cover part 11c by inserting the hanging clamps 5 into the slit parts 11b. Here, a member having the slit part 11b for inserting the hanging clamp 5 (an insert member corresponding to the cut and bent up part 11a) may be formed previously so as to be nearly at a right angle to the upper cover 11. However, this can be inconvenient, for example, in that the packing materials cannot be stacked up for transport. While the upper cover 11 may come with an incision, slit, etc. made in it to serve as the cut and bent up part 11a and the slit part 11b, dust etc. can enter inside the unit main body during transport. Therefore, in this embodiment, the cut and bent up part 11a and the slit part 11b are only printed, and an incision etc. is made to cut and bend up the cut and bent up part 11 before use.

(16) FIG. 4 is a view showing the installation state of the air conditioner according to Embodiment 1 of the present invention before the decorative panel 3 is mounted. As described above, the unit main body 2 has an opening part 2a directed toward the indoor space. In the case where interior work of a building etc. is performed, the decorative panel 3 is mounted after ceiling installation. Before ceiling installation, piping work is performed for an air conditioner. In addition, wiring work etc. of electric equipment such as lighting fixtures is performed. Therefore, dust etc. deposits in an interior passage if the opening part 2a of the unit main body 2 is left exposed to the external space.

(17) FIGS. 5A and 5B are views illustrating the form of use when the upper cover 11 according to Embodiment 1 of the present invention is used as a protective sheet. FIG. 5A is an overall view when the upper cover 11 is mounted on the unit main body 2. FIG. 5B is an enlarged view of the slit part 11b when a protruding portion 5a of the hanging clamp 5 is inserted into the slit part 11b and the unit main body 2 and the upper cover 11 are fixed with each other. The unit main body 2 and the upper cover 11 can be fixed with each other by inserting the protruding portion 5a of the hanging clamp 5 into the slit part 11b. Here, it is possible to prevent the hanging clamp 5 from coming out of the slit part 11b and fix the hanging clamp 5 more firmly, for example, by forming a projection 5b in the protruding portion 5a, inserting the hanging clamp 5 so that the slit part 11b is located further on the inside than the projection 5b, and engaging the slit part 11b with the projection 5b.

(18) As has been described, in the packing material for an air conditioner of Embodiment 1, since the upper cover 11 is utilized as a protective sheet for covering the opening part of the unit main body 2, it is not necessary to use a curing sheet to keep dust etc. out of the unit main body 2, for example, during the period after installation of the unit main body 2 up to mounting of the decorative panel 3. Since the packing material is fixed by inserting the hanging clamp 5 of the unit main body 2 into the slit part 11b of the cut and bent up part 11a of the upper cover 11, engaging with bolts or fixing with tape is not required. Thus, the trouble is saved and waste reduction can be realized. In addition, the upper cover 11 can be used as a paper pattern for positioning the air conditioner in the ceiling. Moreover, deposition of dust etc. can be more efficiently prevented if an antistatic ink (paint) is used for printing on the upper cover 11.

Embodiment 2

(19) In Embodiment 1 described above, the hanging clamps 5 of the unit main body 2 are inserted into the slit parts 11b. However, the present invention is not limited to this example, and other metal fittings, etc. protruding from the unit main body 2 may be inserted into the slit parts 11b. As long as the unit main body 2 can be fixed with its opening part covered, any form of fixation may be adopted, for example, engaging the slit part 11b with a decorative panel fixing bracket for fixing the decorative panel 3 on the unit main body 2. Alternatively, an engaging member for fixing the packing material may be newly provided.

(20) In Embodiment 1 described above, the upper cover 11 is mounted so that the upper surface side of the upper cover 11 and the opening part of the unit main body 2 face each other. However, the upper cover 11 may be mounted so that the lower surface side of the upper cover 11 and the opening part of the unit main body 2 face each other.

(21) In Embodiment 1 described above, the upper cover 11 is used as a protective sheet, but the body part cover 12 etc. may be used instead as a protective sheet.
