Description

  The present invention relates to an air conditioner, and more particularly to heat insulation of a wind direction changing blade.

  As a conventional air conditioner, there is one as shown in FIG. FIG. 2 is a cross-sectional view of a conventional air conditioner.

  In FIG. 2, an air intake 21 is provided on the top surface of the main body 20 of the conventional air conditioner. Inside the heat exchanger 22, indoor air is taken from the air intake 21. An indoor fan 23 is provided to blow out the heat-exchanged air from the air outlet 10 provided below the main body 20. The blower outlet 10 is provided with a wind direction changing blade 5 for changing the direction of the blown air.

  In order to prevent condensation on one side of the wind direction changing blade 5 during the cooling operation, the blowing air is made to flow on both surfaces of the wind direction changing blade 5.

  However, in the above configuration, during the cooling / heating operation, the cold air is directly blown obliquely downward and hits the human body, which is very uncomfortable.

  Therefore, in recent years, in order to improve the comfort of the indoor space during the cooling operation, as shown in FIG. 3, the wind direction changing blade 6 is configured along the lower surface of the air outlet 10 to blow the cool air toward the ceiling. There is an air conditioner. In this case, since cold air hits only the upper surface of the wind direction changing blade 6 and the lower surface is exposed to the outside air, there is a risk of condensation on the lower surface of the wind direction changing blade 6, in order to prevent it The heat insulating material 6 a was pasted on the lower surface of the wind direction changing blade 6.

Further, as shown in FIG. 4, in order to improve the appearance of the wind direction changing blade 7 or to increase the strength, the wind direction changing blade 7 is composed of two resin plates and air is interposed between the two resin plates. There is also an air conditioner in which a layer 7a is provided to form a hollow structure so that condensation is not generated on the lower surface of the wind direction changing blade 7 so as to obtain an air insulation effect (see, for example, Patent Document 1).
JP-A-8-61690

  However, in the configuration of the conventional air conditioner in which the heat insulating material is attached to the wind direction changing blade as shown in FIG. 3, the appearance on the heat insulating material side is bad and the strength is not strong on the heat insulating material side, so the wind direction is changed. It had the subject that the intensity | strength of the whole blade | wing was low.

  Moreover, in the structure of the conventional air conditioner as shown in FIG. 4, although the external appearance of the wind direction changing blade is improved, heat is transmitted by radiation, so the distance between the two resin plates is not affected by radiation. As a result, it had the subject that the whole thickness of a wind direction change blade | wing will become thick.

  The present invention solves the above-described conventional problems, and improves the appearance of the wind direction changing blade, increases the strength, and reduces the overall thickness of the wind direction changing blade, thereby reducing the air conditioning air quality that is inexpensive and has good heat insulation performance. The purpose is to provide.

Although the effect is reduced as compared with a thin aluminum plate, heat insulation is achieved by changing from metal to resin. The effect can be obtained, and radiation can be prevented by the light-colored resin film, so that the entire thickness of the wind direction changing blade can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a cross-sectional view of a wind direction changing blade of an air conditioner according to a first embodiment of the present invention. In addition, about the same part as the said conventional air conditioner, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In FIG. 1, the wind direction changing blade 15 of the air conditioner in the present embodiment is fitted with two sheets of a wind direction changing blade outer side 1 and a wind direction changing blade inner side 2 each made of a resin plate, or bonded by bonding or welding. The hollow layer 4 formed between the wind direction changing blade outer side 1 and the wind direction changing blade inner side 2 is formed by inserting an aluminum thin plate 3 such as an aluminum foil, whereby the wind direction changing blade 15 is made of resin. It will have a layer, an air layer and an aluminum layer.

  The operation and action of the wind direction changing blade 15 of the air conditioner in the present embodiment configured as described above will be described below.

  First, it is well known that the hollow layer 4 serving as the air layer of the wind direction changing blade 15 is an inexpensive method with little heat conduction. However, if it is attempted to reduce the thickness of the wind direction changing blade 15, in terms of heat conduction, heat is transferred due to the influence of radiation even though there is a heat insulation effect. In the present embodiment, the hollow layer 4 is made of aluminum. Since the aluminum layer is formed by putting the thin plate 3 made of metal, radiation can be prevented, and the heat insulation performance of the entire wind direction changing blade 15 can be greatly improved.

As described above, according to the present embodiment, by placing the aluminum thin plate 3 in the hollow layer 4 of the wind direction changing blade 15, the structure prevents radiation and is compared with the structure in which the conventional heat insulating material is attached to one side. Thus, the strength of the entire wind direction changing blade 15 can be increased, the appearance can be improved, and the thickness can be further reduced.

  If an aluminum adhesive tape is attached to the hollow layer 4 of the wind direction changing blade 15 instead of the thin plate 3, the same effect as that of putting the aluminum thin plate 3 is obtained, and the workability is improved. improves.

  If a light-colored resin film is inserted in the hollow layer 4 of the wind direction changing blade 15 in place of the thin plate 3, the heat insulation effect is slightly reduced compared to the case where the aluminum thin plate 3 is inserted, but the wind direction is changed at a low cost. You can make feathers.

  Further, if a foamed resin is inserted in the hollow layer 4 of the wind direction changing blade 15 instead of the thin plate 3, the effect of preventing radiation is slightly reduced in heat conduction than the hollow layer 4 which is an air layer. It is possible to obtain substantially the same effect as the insertion of the aluminum thin plate 3.

  In addition, if white paper is put in the hollow layer 4 of the wind direction changing blade 15 instead of the thin plate 3, the effect of preventing radiation is thin compared with the aluminum thin plate 3, but the heat insulation effect is achieved with an inexpensive material. Obtainable.

  As described above, the wind direction changing blade of the air conditioner according to the present invention is inexpensive, has a good appearance, has high strength, excellent heat insulating properties, and can be reduced in thickness. It can also be applied to applications where necessary.
