Description

Technical Field

[0001] The present invention relates to a sheet for an air conditioner outdoor unit, and particularly to a light-shielding sheet that forms an air circulation space between the lower surface of the light-shielding sheet and the upper surface of the top plate of the air conditioner outdoor unit so as to block direct sunlight and efficiently release heat from the air conditioner outdoor unit, and enables heat to be released from the top plate of the air conditioner outdoor unit.

Background Art

[0002] Conventionally, for an air conditioner outdoor unit, in order to protect the air conditioner outdoor unit from rain and dew and shield strong direct sunlight from the sun to prevent the temperature of the air conditioner outdoor unit from rising, a roof or shade for rain protection may be attached. This roof for the air conditioner outdoor unit is configured such that a frame is separately provided outside the outdoor unit according to the shape of the outdoor unit, and a roof plate such as a corrugated plate made of synthetic resin is attached to the frame. Therefore, there is an advantage that it can be formed according to the size and shape of the air conditioner outdoor unit.

[0003] However, the conventional roof for the air conditioner outdoor unit is necessarily composed of a frame and a roof plate, so there is a problem that its structure becomes complicated, expensive, and its installation becomes difficult. In addition, in order to shield direct sunlight from the sun, especially strong direct sunlight in midsummer, a shade for an air conditioner outdoor unit as disclosed in Patent Document 1 has been proposed. This shade for the air conditioner outdoor unit consists of a light-shielding sheet (light-shielding board) and a reflector including a metal film laminated on one surface of this light-shielding sheet, and this is arranged so as to directly contact the top plate of the air conditioner outdoor unit, and the shade for the air conditioner outdoor unit is configured to be tied and fixed to the air conditioner outdoor unit with a flat belt, so that strong direct light rays can also be blocked. Further, its structure is simpler than that of a roof type, and it has an advantage that it can be easily attached to the air conditioner outdoor unit.

[0004] However, because this shade for the air conditioner's outdoor unit is in direct contact with the top of the outdoor unit, while it can block strong direct sunlight, the top of the outdoor unit becomes insulated by the shade, and the heat produced inside the outdoor unit is blocked by the shade, hindering heat dissipation from the top of the outdoor unit, thus reducing its heat dissipation efficiency. Furthermore, when the outdoor unit of an air conditioner heats up, the refrigerant cooling efficiency decreases, especially during cooling operation in the summer, leading to a reduction in cooling capacity and resulting in wasted electricity.

[0005] To address this problem, a shading sheet for air conditioner outdoor units has been proposed that blocks direct sunlight and allows for efficient heat dissipation from the outdoor unit by creating a gap between the top plate of the outdoor unit and the shading sheet (shading board) that allows air to circulate, thereby enabling heat to be released from the top plate of the outdoor unit as well (see Patent Document 2). As shown in Figure 11, this shading sheet for the air conditioner outdoor unit mainly consists of a shading sheet 1 of sufficient size to block direct sunlight from the top side of the air conditioner outdoor unit 5. A light-reflecting layer is integrally formed on one side of the shading sheet 1 to reflect direct sunlight, and two or more (three in this example) gap-forming members 2 are arranged side by side on the lower surface of the shading sheet 1 to form an air circulation space C. Through holes H are drilled in the locations where the gap-forming members 2 are provided in the shading sheet 1, and fasteners 3 are inserted through these holes so that the fasteners 3 can be attached to the air conditioner outdoor unit 5 and fixed in place.

[0006] [Patent Document 1] Utility Model Registration No. 3141403 Gazette [Patent Document 2] Utility Model Registration No. 3179448 Gazette [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] By the way, in the case of the light-shielding sheet for air conditioner outdoor units disclosed in Patent Document 2, it is necessary to provide a gap-forming member 2 to the light-shielding sheet 1, which increases costs and has the problem of making it difficult to form a large air circulation space.

[0008] In view of the above problems, the present invention aims to provide a light-shielding sheet for an air conditioner outdoor unit that, without providing a gap-forming member in the light-shielding sheet, creates a large air circulation space between the lower surface of the light-shielding sheet and the upper surface of the top plate of the air conditioner outdoor unit, thereby enabling heat to be released from the top plate of the air conditioner outdoor unit. [Means for solving the problem]

[0009] To achieve the above objective, the present invention provides a light-shielding sheet for an air conditioner outdoor unit, which is installed to cover the top plate of the air conditioner outdoor unit via adhesive members. The light-shielding sheet is characterized in that the adhesive members are attached parallel to the light-shielding sheet at intervals greater than the depth dimension of the top plate of the air conditioner outdoor unit, and one adhesive member is attached along the upper front edge of the air conditioner outdoor unit, and the other adhesive member is attached along the upper rear edge of the air conditioner outdoor unit, thereby creating an air circulation space between the lower surface of the light-shielding sheet and the upper surface of the top plate of the air conditioner outdoor unit that is larger than the thickness of the adhesive members.

[0010] In this case, the upper surface of the light-shielding sheet can be formed as an inclined surface.

[0011] The light-shielding sheet for an air conditioner outdoor unit according to claim 2, characterized in that the upper surface of the light-shielding sheet is formed in the shape of a triangular roof.

[0012] Furthermore, the light-shielding sheet may be provided with an overhang portion that extends in front of and / or behind the outdoor unit of the air conditioner. [Effects of the Invention]

[0013] According to the present invention, the light-shielding sheet for air conditioner outdoor units does not require a gap-forming member to be provided in the light-shielding sheet. This allows for the blocking of direct sunlight and efficient heat dissipation from the air conditioner outdoor unit by forming an air circulation space between the lower surface of the light-shielding sheet and the upper surface of the top plate of the air conditioner outdoor unit, which is larger in dimension than the thickness of the adhesive member. This also allows heat to be released from the top plate of the air conditioner outdoor unit.

[0014] Furthermore, by forming the upper surface of the shading sheet into a sloping surface such as a triangular roof shape, rainwater that falls on the upper surface of the shading sheet can be quickly drained.

[0015] Furthermore, by providing the light-blocking sheet with an overhang that extends in front of and / or behind the outdoor unit of the air conditioner, it is possible to block direct sunlight from shining on the front and / or rear of the outdoor unit of the air conditioner, thereby preventing the temperature of the outdoor unit from rising.

Mode for Carrying Out the Invention

[0017] Hereinafter, embodiments of the light-shielding sheet for an air conditioner outdoor unit of the present invention will be described based on the drawings.

[0018] Figs. 1 to 3 show a first embodiment of the light-shielding sheet for an air conditioner outdoor unit of the present invention. This light-shielding sheet for an air conditioner outdoor unit is configured such that the light-shielding sheet 1 is disposed to cover the top plate 51 of the air conditioner outdoor unit 5 via the attaching member 4. The attaching member 4 is attached in parallel to the light-shielding sheet 1 at an interval W larger than the depth dimension D of the top plate 51 of the air conditioner outdoor unit 5. One side of the attaching member 4 is attached along the front edge of the top plate 51 of the air conditioner outdoor unit 5 (the upper front edge of the air conditioner outdoor unit 5), and the other side of the attaching member 4 is attached along the rear edge of the top plate 51 of the air conditioner outdoor unit 5 (the upper rear edge of the air conditioner outdoor unit 5). By doing so, an air circulation space C with a dimension T larger than the thickness t of the attaching member 4 is formed between the lower surface 11 of the light-shielding sheet 1 and the upper surface of the top plate 51 of the air conditioner outdoor unit 5.

[0019] In this case, various light-shielding members used as light-shielding sheets (light-shielding boards) for air conditioner outdoor units can be used for the light-shielding sheet 1. In particular, a sheet-like member with a thickness of about 0.05 to 10 mm, preferably about 0.05 to 0.3 mm for hard materials and about 1 to 5 mm for soft materials such as foamed resin, which can maintain its shape when bent, can be suitably used. Specifically, a sheet-like laminated member consisting of a light-impermeable layer 1a such as an aluminum vapor-deposited layer, an aluminum foil layer, or a synthetic paper layer, and protective layers 1b and 1c formed on both sides thereof such as a resin layer, a foamed resin layer, or a painted layer (in this embodiment, a sheet-like laminated member with a thickness of about 0.15 mm consisting of a light-impermeable layer 1a made of an aluminum foil layer of about 0.01 mm and protective layers 1b and 1c made of resin layers formed on both sides thereof) is used.

[0020] The adhesive member 4 can use magnets such as rubber magnets, ferrite magnets, and neodymium magnets, adhesives, hook-and-loop fasteners, etc., either individually or in combination. Rubber magnets and adhesives can be arranged in a strip-like configuration as shown in Figure 2(a), while powerful magnets such as ferrite magnets and neodymium magnets can be arranged intermittently as shown in Figure 2(b). Here, the adhesive (including adhesives in this specification) can be any conventionally used adhesive such as urea-based, melamine-based, phenol-based, resorcinol-based, isocyanate-based, vinyl acetate-based, chloroprene-based, epoxy-based, urethane-based, modified silicone-based, or hot-melt adhesives, or any conventionally used adhesive such as acrylic-based, urethane-based, rubber-based, silicone-based, or hot-melt adhesives. In addition, the adhesive can be used alone, or a double-sided adhesive tape (including double-sided adhesive tape in this specification) can be used. Furthermore, a release paper or release film (not shown) is provided on the surface of the adhesive during manufacturing, so that when the user uses the light-shielding sheet for the air conditioner outdoor unit, they can peel off the release paper or release film and adhere it to the air conditioner outdoor unit 5.

[0021] This shading sheet for an air conditioner outdoor unit is installed by attaching adhesive members 4 parallel to the shading sheet 1 at a spacing W greater than the depth dimension D of the top plate 51 of the air conditioner outdoor unit 5. By attaching one adhesive member 4 along the front edge of the top plate 51 of the air conditioner outdoor unit 5 and the other adhesive member 4 along the rear edge of the top plate 51 of the air conditioner outdoor unit 5, the shading sheet 1 can be installed in a tunnel shape due to the difference of several centimeters between the spacing W of the adhesive members 4 attached parallel to the shading sheet 1 and the depth dimension D of the top plate 51 of the air conditioner outdoor unit 5. This eliminates the need for conventional gap-forming members 2 in the shading sheet 1, and allows for efficient heat dissipation from the air conditioner outdoor unit 5. It creates an air circulation space C between the lower surface 11 of the shading sheet 1 and the upper surface of the top plate 51 of the air conditioner outdoor unit 5 with a dimension T greater than the thickness t of the adhesive members 4 (specifically, several centimeters), enabling heat to be released from the top plate 51 of the air conditioner outdoor unit 5. Here, the light-shielding sheet 1 can be installed so that it protrudes from both sides in the width direction of the air conditioner outdoor unit 5 by using a component that is approximately the same size as the width dimension of the air conditioner outdoor unit 5, or by using a component that is larger in size. Furthermore, the light-blocking sheet 1 should be attached to the air conditioner outdoor unit 5 using appropriate fasteners 6, such as strings, as needed.

[0022] Furthermore, by installing the shading sheet 1 in a tunnel shape on the top plate 51 of the air conditioner outdoor unit 5, the upper surface 12 of the shading sheet 1 can be made inclined, thereby allowing rainwater that falls on the upper surface 12 of the shading sheet 1 to be drained quickly. In this case, a tunnel-shaped inclined surface can be easily formed by creating valley fold lines 13a at the points where the light-shielding sheet 1 is detached from the adhesive members 4 at both ends.

[0023] Furthermore, the inclined surface of the light-shielding sheet 1 can be formed into a triangular roof shape by forming mountain fold lines 13g at intermediate positions away from the adhesive members 4 at both ends of the light-shielding sheet 1, as shown in Figure 4, which is the first modified example of the first embodiment of the light-shielding sheet for the outdoor unit of the air conditioner of the present invention. This allows rainwater that falls on the upper surface 12 of the light-blocking sheet 1 to be quickly drained, and also makes it more difficult for snow to accumulate. In this case, as shown in the second modified example of the first embodiment of the light-shielding sheet for the outdoor unit of the air conditioner of the present invention, as shown in Figure 5, the shape of the light-shielding sheet 1 can be stably maintained by arranging a skeletal member 7 with flexibility and rigidity, such as a thin metal plate or wire, on the back surface of the light-shielding sheet 1. Here, by forming two or more parallel mountain fold lines 13g on the light-shielding sheet 1, the upper surface 12 of the light-shielding sheet 1 can be formed into a polygonal roof shape.

[0024] In this embodiment, the light-shielding sheet 1 is installed in a tunnel shape on the top plate 51 of the air conditioner outdoor unit 5. However, as shown in Figures 6 to 7, in the second embodiment of the light-shielding sheet for air conditioner outdoor units of the present invention, the light-shielding sheet 1 can be provided with an overhang portion 14 that extends forward of the air conditioner outdoor unit 5. This shading sheet for the air conditioner outdoor unit is installed by covering the top plate 51 of the air conditioner outdoor unit 5 with the shading sheet 1 via adhesive members 4. The adhesive members 4 are attached parallel to the shading sheet 1 at a spacing W that is larger than the depth dimension D of the top plate 51 of the air conditioner outdoor unit 5 compared to the first embodiment, with one side of the adhesive member 4 along the upper edge of the front surface 52 of the air conditioner outdoor unit 5 (upper front edge of the air conditioner outdoor unit 5), and the other side of the adhesive member 4 along the rear edge of the top plate 51 of the air conditioner outdoor unit 5 ( By attaching them along the upper rear edge of the air conditioner outdoor unit 5, an air circulation space C with dimensions T greater than the thickness t of the adhesive member 4 is formed between the lower surface 11 of the light-shielding sheet 1 and the upper surface of the top plate 51 of the air conditioner outdoor unit 5, and an overhang portion 14 is formed that extends forward of the air conditioner outdoor unit 5. In this case, to enable the light-shielding sheet 1 to be installed in a tunnel shape on the top plate 51 of the air conditioner outdoor unit 5, valley fold lines 13a and 13b can be formed at the ends of the light-shielding sheet 1 that are detached from the adhesive members 4, and a mountain fold line 13c can be formed at the tip of the eaves portion 14. Furthermore, by providing the light-blocking sheet 1 with an overhang portion 14 that extends in front of the air conditioner outdoor unit 5, direct sunlight shining on the front surface 52 of the air conditioner outdoor unit 5 can be blocked, thereby preventing the temperature of the air conditioner outdoor unit from rising.

[0025] Here, as shown in Figure 8(a), the first modified example of the second embodiment of the light-shielding sheet for the air conditioner outdoor unit of the present invention, the adhesive member 4 on the other side can be attached along the upper edge (upper rear edge) of the rear surface 53 of the air conditioner outdoor unit 5. In this case, in order to install the light-shielding sheet 1 in a tunnel shape on the top plate 51 of the air conditioner outdoor unit 5, valley fold lines 13b and 13d can be formed at the ends of the light-shielding sheet 1 that are detached from the adhesive members 4, and a mountain fold line 13c can be formed at the tip of the eaves portion 14.

[0026] Furthermore, as shown in Figure 8(b), a second modified example of the second embodiment of the air conditioner outdoor unit light shielding sheet of the present invention, the adhesive member 4 on the other side is attached along the upper edge (upper rear edge) of the rear surface 53 of the air conditioner outdoor unit 5, and the light shielding sheet 1 is divided into light shielding sheet 1A and light shielding sheet 1B near the front edge (upper front edge) of the top plate 51 of the air conditioner outdoor unit 5, and can be attached via the adhesive member 4 near the front edge (upper front edge) of the top plate 51 of the air conditioner outdoor unit 5. In this case, in order to install the light-shielding sheet 1 in a tunnel shape on the top plate 51 of the air conditioner outdoor unit 5, valley fold lines 13a, 13a can be formed at the ends of the light-shielding sheet 1A that are detached from the adhesive members 4, a valley fold line 13b can be formed at one end of the light-shielding sheet 1B that is detached from the adhesive member 4, and a mountain fold line 13c can be formed at the tip of the eaves portion 14.

[0027] Furthermore, the other configurations and operations of this embodiment are the same as those of the light-shielding sheet for the air conditioner outdoor unit in the first embodiment.

[0028] Furthermore, as shown in Figures 9 to 10, as in the third embodiment of the shading sheet for the air conditioner outdoor unit of the present invention, the shading sheet 1 can be provided with an overhang portion 14 that extends forward of the air conditioner outdoor unit 5 and an overhang portion 15 that extends backward. This shading sheet for an air conditioner outdoor unit is installed by covering the top plate 51 of the air conditioner outdoor unit 5 with the shading sheet 1 via adhesive members 4. The adhesive members 4 are attached parallel to the shading sheet 1 at a larger spacing W than the depth dimension D of the top plate 51 of the air conditioner outdoor unit compared to the second embodiment. By attaching one side of the adhesive member 4 along the upper edge of the front surface 52 of the air conditioner outdoor unit 5 (upper front edge of the air conditioner outdoor unit 5) and the other side of the adhesive member 4 along the upper edge of the rear surface 53 of the air conditioner outdoor unit 5 (upper rear edge of the air conditioner outdoor unit 5), an air circulation space C with a dimension T larger than the thickness t of the adhesive member 4 is formed between the lower surface 11 of the shading sheet 1 and the upper surface of the top plate 51 of the air conditioner outdoor unit, and an overhang portion 14 extending forward and an overhang portion 15 extending backward of the air conditioner outdoor unit 5 are formed. In this case, in order to install the light-shielding sheet 1 in a tunnel shape on the top plate 51 of the air conditioner outdoor unit 5, valley fold lines 13a are formed at the ends of the light-shielding sheet 1 that are detached from the adhesive members 4, and mountain fold lines 13c and 13f are formed at the ends that will be the tips of the eaves 14 and 15. Each can be formed. Furthermore, by providing the light-blocking sheet 1 with overhangs 14 and 15 that extend in front of and behind the air conditioner outdoor unit 5, direct sunlight shining on the front 52 and rear 53 of the air conditioner outdoor unit 5 can be blocked, thereby preventing the temperature of the air conditioner outdoor unit from rising.

[0029] Furthermore, the other configurations and functions of this embodiment are the same as those of the light-shielding sheet for the air conditioner outdoor unit in the first and second embodiments.

[0030] The present invention has been described above based on its embodiments, but the present invention is not limited to the configuration described in the above embodiments, and its configuration can be modified as appropriate without departing from the spirit of the invention. [Industrial applicability]

[0031] The shading sheet for air conditioner outdoor units of the present invention can be suitably used for applications as a shading sheet for air conditioner outdoor units because it does not require a gap-forming member to be provided in the shading sheet, and a large air circulation space is formed between the lower surface of the shading sheet and the upper surface of the top plate of the air conditioner outdoor unit, allowing heat to be released from the top plate of the air conditioner outdoor unit as well.
