Description

The present invention relates to a heat shield sheet for an air conditioner outdoor unit. In particular, the present invention relates to the structure of a heat shield sheet for an air conditioner outdoor unit that covers the outdoor unit in order to shield the outdoor unit of the air conditioner installed outdoors from the radiant heat of direct sunlight.

A so-called air conditioner is a typical example of air conditioning equipment for making a room comfortable. Generally, a separable air conditioner is composed of an indoor unit equipped with an indoor heat exchanger and a fan, and an outdoor unit equipped with an outdoor heat exchanger and a compressor.

The outdoor unit of an air conditioner for home use has a fan installed inside a rectangular parallelepiped housing. The inside of the air conditioner outdoor unit is air-cooled by driving the fan, taking in the atmosphere from the intake port opened on the back side of the housing, and exhausting it from the exhaust port opened on the front side of the housing.

Generally, since the air conditioner outdoor unit is installed outdoors, the housing is exposed to direct sunlight for a long time, especially in summer. As a result, the internal temperature of the air conditioner outdoor unit rises through the housing. Even if the air conditioner temperature is set in order to obtain a refreshing feeling indoors, it may be difficult to obtain a desired temperature because the internal temperature of the air conditioner outdoor unit is rising. Further, if the difference between the internal temperature of the air conditioner outdoor unit and the set temperature in the room due to direct sunlight is large, there is a problem that power consumption is also added.

Against such a background, a cover forming body composed of an aluminum yarn knitting woven sheet or an aluminum vapor deposition film or a laminated foam sheet in which a sheet is laminated on a foam sheet, and has a coating forming portion covering the entire surface or a part of the upper surface of the air conditioner outdoor unit. A heat shield cover for an air conditioner outdoor unit is disclosed (see, for example, Patent Document 1).

Further, from such a background, the outer surface of the air conditioner outdoor unit excluding the exhaust port is configured to be covered with a heat shield sheet, and a plurality of heat shield sheet fixtures are attached to the outer surface of the air conditioner outdoor unit using magnets. A heat shield sheet for an air conditioner outdoor unit is disclosed in which a heat shield sheet is detachably stretched between a plurality of heat shield sheets fixed (see, for example, Patent Document 2).

The heat shield cover for the air conditioner outdoor unit according to Patent Document 1 is lightweight, easy to attach to or remove from the air conditioner outdoor unit, can efficiently prevent the air conditioner outdoor unit from being heated by direct sunlight, and It is said that it has excellent heat insulation.

However, the heat shield cover for the air conditioner outdoor unit according to Patent Document 1 can improve the heat insulating effect as compared with the commercially available awning cover for the air conditioner outdoor unit, but is configured to shield the front surface and both side surfaces of the air conditioner outdoor unit. Therefore, there is a problem that it is difficult to sufficiently shield the air conditioner outdoor unit from heat. There is a demand for a heat shield sheet for an air conditioner outdoor unit that shields the outer surface of the air conditioner outdoor unit except for the bottom surface.

The heat shield sheet for the air conditioner outdoor unit according to Patent Document 2 can firmly attach the heat shield sheet to the air conditioner outdoor unit, is easy to put on and take off, and can be attached to the heat shield sheet fixture to make the air conditioner outdoor unit. It is said that it will not be damaged.

Since the heat shield sheet for the air conditioner outdoor unit according to Patent Document 2 covers the upper surface and the front surface of the air conditioner outdoor unit with the heat shield sheet via the air layer, it is compared with the heat shield cover for the air conditioner outdoor unit according to Patent Document 1. Therefore, it is possible to suppress an increase in the internal temperature of the air conditioner outdoor unit.

However, the outer shape of the air conditioner outdoor unit for home or business use differs depending on the manufacturer. In the heat shield sheet for the air conditioner outdoor unit according to Patent Document 2, since the upper surface and the front surface of the air conditioner outdoor unit are stretched with the heat shield sheet, if the outer shape of the air conditioner outdoor unit is different, the heat shield sheet of the corresponding size is used. You need to prepare. Even if the outer shape of the air conditioner outdoor unit is different, a versatile heat shield sheet for the air conditioner outdoor unit is required so as to cope with this. The above can be said to be the subject of the present invention.

The present invention has been made in view of such a problem, and is a heat shield sheet for an air conditioner outdoor unit that covers the outer surface of an air conditioner outdoor unit so as to be heat shieldable, and is versatile enough to be applied to an air conditioner outdoor unit having a different outer shape.

Although the heat shield sheet for an outdoor unit according to the present invention has been described above using the above embodiment, the heat shield sheet for an outdoor unit according to the present invention is not limited to the contents of the above embodiment.
For example, as the configuration of the second band member, the second band member is inserted and fixed in the holes arranged at the side edges of the third side surface sheet portion 1f and the fourth side surface sheet portion 1g. The band member may be any as long as it can fix the front seat portion and the back seat portion. For example, the band member may be fixed by the hook-and-loop fastener body described as a modification of the first band member, or the third band member. It may be fixed by the belt described as described above or a band member having a hook at the tip.

Further, as the configuration of the third band member, the side edge of the front seat portion and the side edge of the back seat portion have been described as being moored on the bottom surface side, but the side edge of the first side surface seat portion and the second side surface seat portion have been described. The side edge of the surface may be moored on the bottom surface side, or both may be combined.

Further, in the first to fourth embodiments, a configuration in which the ventilation portion is open, a configuration in which the ventilation portion can be opened and closed, a configuration in which a mesh sheet is arranged in the ventilation portion, and a plurality of bands in the ventilation portion. Although the configuration in which the plate-shaped fins are arranged has been described, the above-mentioned plurality of configurations can be used in combination in an outdoor unit having a plurality of vents.

Further, in the fifth embodiment, the eaves portion has been described as being fixed to the upper surface sheet portion, but the present invention is not limited to this. The eaves portion may be arranged between the exhaust port Ve and the ventilation port Vi without obstructing the ventilation of the ventilation port of the outdoor unit, and may be fixed to the seat portion other than the upper surface seat portion.
Similarly, in the sixth embodiment, the eaves portion formed by cutting out the front sheet portion and the back sheet portion has been described, but the eaves portion may be formed by cutting out any of the sheet portions, for example. The eaves portion may be formed by cutting out the upper surface sheet portion.

In the present invention, a versatile heat shield sheet can be realized by providing a second band member for mooring the other side edges of the front seat portion and the back seat portion, but other outdoor units. As an adjustment method according to the size of, for example, as shown in FIG. 26 or FIG. 28, a slit SL is provided between each sheet portion excluding the upper surface sheet portion, and a plurality of rows of holes 1h are provided in the side edge portion of each sheet portion. By providing the above, the hole 1h used for fixing the heat shield sheet can be changed according to the size of the outdoor unit, and a versatile heat shield sheet can be realized.
