[0019] Preferred embodiments of the present invention will be described with reference to the accompanying drawings. Note that the embodiments described below do not limit the content of the present invention as described in the claims. Furthermore, not all of the configurations described below are necessarily essential requirements for the present invention.

[0020] A first embodiment of the present invention will be described below with reference to Figures 1 to 4. A sunshade device 1 for an air conditioner outdoor unit of this embodiment includes a heat insulating material 2, a heat-shielding waterproof sheet 3 that covers the heat insulating material 2 from above, a heat-shielding sheet 4 for the top plate that is placed between the heat insulating material 2 and the heat-shielding waterproof sheet 3, a base 5 that holds the heat insulating material 2, and a magnet 7 that fixes the heat insulating material 2 to a top surface 6A of an air conditioner outdoor unit 6.

[0021] The heat insulating material 2 is made of wool and polylactic acid fiber. This heat insulating material 2 is used in the walls, ceilings, under floors, etc. of houses, and for example, the environmentally friendly board-shaped heat insulating material disclosed in Japanese Patent Application Laid-Open No. 2008-303597 can be used. Furthermore, this heat insulating material may contain, for example, 50 to 70% wool and 30 to 50% polylactic acid fiber, and have a density of 30 kg / m 3 The above materials can be suitably used. Note that the higher the density of the heat insulating material, the harder the heat insulating material becomes, and the higher the resilience and shape stability.

[0022] The polylactic acid fibers that make up this insulating material 2 are preferably made from agricultural crops such as corn, and by using agricultural products as raw materials, the insulating material 2 can be made using only materials derived from natural sources. Furthermore, by forming the insulating material 2 from wool and polylactic acid fibers, the insulating material 2 has a moderate resilience and a stable shape. Furthermore, the wool that makes up the insulating material 2 has excellent insulating properties, as well as excellent weather resistance, moisture absorption, and moisture release properties.

[0023] Furthermore, wool with polylactic acid fibers partially heat-sealed is preferably used as the insulating material 2. By partially heat-sealing the wool and polylactic acid fibers, the insulating material does not come apart and maintains a stable shape more reliably. Furthermore, because the shape is maintained by heat fusion without the use of adhesive, there is no need to worry about volatile chemicals contained in adhesives, and the pillow can be used safely.

[0024] Furthermore, a material that has been treated with boric acid is preferably used as the heat insulating material 2. By including boric acid, the heat insulating material can obtain the effects of preventing mold, insects, and decay.

[0025] The planar shape of the heat insulating material 2 is formed into a rectangular shape that can cover the rectangular top surface 6A of the outdoor unit 6.

[0026] The heat-shielding waterproof sheet 3 is preferably a polyethylene sheet with UV weather resistance added as a waterproof sheet, which is then given a pearlescent white finish to diffuse direct sunlight and provide heat-shielding properties to prevent the temperature inside the sheet from rising. However, the heat-shielding waterproof sheet 3 of the present invention is not limited to the above-mentioned configuration as long as it has heat-shielding and waterproof properties.

[0027] The heat-shielding waterproof sheet 3 has a rectangular top surface 3A and four side surfaces 3B, each consisting of front, rear, left, and right sides, and is box-shaped with an open bottom. The box-shaped, open bottom of the heat-shielding waterproof sheet 3 is shaped so that it can cover the top surface 6A and the upper four corners 6B of a box-shaped air conditioner outdoor unit from above.

[0028] The height dimension L1 of the side portion 3B of the heat-shielding waterproof sheet 3 is formed to be larger than the height dimension L2 of the heat insulating material 2. Even when the heat-shielding waterproof sheet 3 contains the heat insulating material 2 together with the base 5 inside, there is enough space secured below the inside of the side portion 3B to cover the four corners 6B of the upper part of the air conditioner outdoor unit 6.

[0029] The heat shielding sheet 4 for the tabletop is made of a sheet material formed by sandwiching an air layer made of bubble cushioning material (polyethylene bubble cushioning material) or the like between a pair of aluminum foil sheets. It has excellent heat shielding and insulation performance due to the heat insulating properties of the air layer that blocks heat transfer and the infrared heat insulating properties of the aluminum foil. However, the heat shielding sheet 4 for the tabletop is not limited to the above-mentioned configuration as long as it has heat shielding properties.

[0030] The base 5 has a side portion 5A and a bottom portion 5B that hold the side and bottom surfaces of the heat insulating material 2.

[0031] The side portion 5A of the base 5 is formed in a frame shape that holds the entire side circumference of the insulation material 2, and the bottom portion 5B of the base 5 is formed in a lattice shape that holds the entire bottom surface of the insulation material 2, and the side portion 5A and the bottom portion 5B are made of metal plates such as steel plates that have been treated with rust prevention such as zinc plating, assembled in a lattice shape, which makes the base 5 lightweight and maintains the breathability of the insulation material 2 held by the base 5.

[0032] Magnets 7 are scattered and arranged in multiple locations on the bottom surface 5B of the base 5. The magnets 7 are sheet-shaped magnets cut into rectangular shapes of 50 mm x 25 mm, but are not limited to this.

[0033] The installation method for the sunshade device 1 for an air conditioner outdoor unit configured as described above will now be described. As shown in Figure 4, the magnets 7 of the sunshade device 1 for an air conditioner outdoor unit are attached to the top surface 6A of the air conditioner outdoor unit 6, and the device is installed so that the four upper corners 6B of the air conditioner outdoor unit 6 are located inside the heat-shielding waterproof sheet 3. As shown in Figures 1 and 4, the heat-shielding waterproof sheet 3 is designed not to obstruct the air flow F from the air outlet 6C of the air conditioner outdoor unit 6.

[0034] In this embodiment, the device comprises an insulating material 2 installed on the top surface 6A of the air conditioner outdoor unit 6, and a heat-shielding waterproof sheet 3 covering the insulating material 2 from above, and the insulating material 2 is made of wool.

[0035] In this case, wool, which has excellent insulating and weather-resistant properties, is used as the insulating material 2, and the heat-shielding waterproof sheet 3 is used to block direct sunlight from reaching the top surface 6A of the air conditioner outdoor unit 6, thereby preventing the air conditioner outdoor unit 6 from heating up in the summer or dropping to a low temperature due to snow accumulation in the winter, thereby reducing the air conditioner's power consumption throughout the year, regardless of whether it is summer or winter.

[0036] In this embodiment, the heat-shielding waterproof sheet 3 is provided so as to be able to cover the four corners 6B of the upper part of the air conditioner outdoor unit 6.

[0037] In this case, by placing the top of the air conditioner outdoor unit 6 in the shade created by the heat-shielding waterproof sheet 3, it is possible to suppress the temperature rise and snow accumulation of the air conditioner outdoor unit 6, thereby reducing the power consumption of the air conditioner.

[0038] In this embodiment, a heat shielding sheet 4 for the top surface is provided between the heat insulating material 2 and the heat shielding waterproof sheet 3.

[0039] In this case, the heat shielding properties of the sunshade device 1 for an air conditioner outdoor unit can be further improved.

[0040] In this embodiment, the top heat shield sheet 4 is made of aluminum foil.

[0041] In this case, the heat shielding property of the aluminum foil can improve the heat shielding property of the air conditioner outdoor unit sunshade device 1.

[0042] In addition, in this embodiment, a plurality of magnets 7 are scattered to detachably fix the heat insulating material 2 side to the top surface 6A of the air conditioner outdoor unit 6, and the contact points between the heat insulating material 2 side and the top surface 6A of the air conditioner outdoor unit 6 are limited to the plurality of magnets 7.

[0043] In this case, it is possible to improve the ease of installation of the air conditioner outdoor unit sunshade device 1. Furthermore, a gap is formed between the air conditioner outdoor unit sunshade device 1 and the top surface 6A of the air conditioner outdoor unit 6 other than the contact points between the air conditioner outdoor unit sunshade device 1 and the top surface 6A of the air conditioner outdoor unit 6 by the magnet 7, and by using this gap as an air passage, it is possible to limit the heat exchange between the air conditioner outdoor unit sunshade device 1 and the air conditioner outdoor unit 6, which are heated by direct sunlight, and thereby improve the thermal insulation provided by the air conditioner outdoor unit sunshade device 1.

[0044] In addition, this embodiment is provided with a base 5 that holds the insulating material 2, and the base 5 has a side portion 5A that holds the side of the insulating material 2 and a bottom portion 5B that holds the bottom of the insulating material 2, and the bottom portion 5B is formed in a lattice pattern.

[0045] In this case, the weight of the sunshade device 1 for an air conditioner outdoor unit can be reduced, and by making the base 5 breathable, the moisture permeability of the wool used in the heat insulating material 2 can be prevented from being impaired.

[0046] The above describes in detail the embodiments of the present invention, but the present invention is not limited to the above embodiments. For example, the materials and shapes of the heat-shielding waterproof sheet, the heat-shielding sheet for the ceiling, the base, and the magnets can be changed as appropriate.
