[Composition] A blowout louver 15 provided at the blowout port 4 of the air conditioner for changing the wind direction of the conditioned air blown out from the blowout port 4 is formed of foamed resin, and the temperature of the region of the blowout louver 15 that does not come into contact with the cool air Prevents dew condensation and prevents condensation.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a blowout louver provided at a blowout port of an air conditioner.

[0002]

[Prior Art]

 In a conventional air conditioner, a blowout louver is installed at the blowout port where the conditioned air cooled or heated by the heat exchanger installed in the unit body blows out through the ventilation passage. By rotating the louver, the wind direction of the conditioned air can be changed.

[0003]

[Problems to be solved by the device]

 In the conventional air conditioner, from the viewpoint of aesthetics, the outlet generally has a larger opening area than the air passage inside the unit body, and the outlet louver also has a large shape in accordance with the outlet. Have For this reason, the central part of the blowout louver is in contact with the cool air blown from the blowout port, while the peripheral part is not in contact with the cool air and is in contact with the room air.

The temperature of the peripheral part of the blow-out louver is lowered by heat conduction with the central part cooled by cold air, and warm moist air in the room comes into contact there to cause dew condensation. There was a risk of dripping to wet the floor surface. In particular, this phenomenon was remarkable after the operation of the air conditioner was started and before the room was cooled to a predetermined temperature.

On the other hand, there is also one in which a flocking member made of a resin-based short fiber is attached to the surface of the blowout louver or an electrodeposition flocking process is performed so that condensed water can be retained therein. The attachment of the member has a drawback that the cost is high, and there is a problem that mold is generated and dust adheres because it is in a wet state because it has condensed water.

The present invention has been made in view of the above, and it is an object of the present invention to suppress dew condensation in the blowout louver of an air conditioner.

[0007]

[Means for Solving the Problems]

 The blowout louver of the air conditioner of the present invention has a blowout louver provided at the blowout port of the air conditioner for changing the direction of the conditioned air blown from the blowout port, and is made of a foaming material. Characterize.

[0008]

[Action]

 Since the present invention has the above-mentioned structure, the blowout louver is made of foamed resin and its thermal conductivity is small, so that the area of the blowout louver that comes into contact with the cool air blown from the blowout port is cooled. However, the temperature in the area of the blowout louver that does not come into contact with the cold air is not easily lowered, and even if indoor air comes into contact with this area, dew condensation is prevented.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a vertical sectional view of a ceiling-embedded air conditioner using a blowout louver according to this embodiment, FIG. 2 is a plan view of a ceiling panel of the air conditioner, and FIG. 3 is a blowout louver according to this embodiment. It is a perspective view.

A heat exchanger 7, a drain pan 10, a blower 6, a motor 5, a baffle plate 12 and the like are arranged inside the unit body 2 of the air conditioner embedded in the ceiling 1, and the unit body 2 A substantially square ceiling panel 8 covering the lower opening is detachably attached to the. A substantially square suction port 3 is formed in the central portion of the ceiling panel 8, and a blowout port 4 is formed around the suction port 3. A suction grill 11 is fitted in the suction port 3, and a filter 13 is provided behind it.

A blow-out louver 15 is provided at the blow-out port 4, and is rotated by a motor (not shown) so that the blow-out direction of the conditioned air can be changed. The blowout louver 15 is formed of a low foaming resin such as polyethylene (PS) or acrylonitriletributadiene styrene (ABS). The blow-out louver can be reinforced by inserting a base material such as a sheet metal and molding the foamed resin.

An air passage 14 of conditioned air that has passed through the heat exchanger 7 is formed between the outlet 4 and the heat exchanger 7, and from the viewpoint of aesthetics, the outlet 4 is It has a larger opening area than the air passage 14.

In the present embodiment, when the blower 6 is driven by the motor 5, the air in the chamber 9 passes from the suction port 3 through the suction grill 11 and is guided by the baffle plate 12 to be sucked into the blower 6 and urged. To be done. Then, in the process of passing through the heat exchanger 7, it is cooled or heated to become conditioned air, which is blown out through the air passage 14 into the chamber 9 through the outlet 4.

As described above, the outlet 4 has a larger opening area than the air passage 14 in the unit body 2, and therefore the outlet louver 15 also has a shape larger than the air passage 14 in accordance with the outlet 4. However, since the blow-out louver 15 is made of foamed resin and has a low heat conductivity, the central portion of the blow-out louver 15 that comes into contact with the cold air blown out from the blow-out port 4 is cooled but does not come into contact with the cold air. The temperature in the area is hard to be lowered. As a result, the peripheral areas do not condense on contact with warm, moist air in the room.

Although the above embodiment relates to the blowout louver of the ceiling-embedded air conditioner, the present invention is not limited to the ceiling-embedded air conditioner and is widely applicable to other types of air conditioners. Can be applied.

[0016]

[Effect of the device]

 According to the present invention, since the blowout louver is made of foamed resin and its thermal conductivity is low, the temperature in the area that does not come into contact with the cool air from the blowout port is less likely to drop, so that condensation occurs due to contact with indoor air. Can be suppressed, and the dew condensation water can be prevented from dripping on the floor surface. Further, unlike the conventional case in which flocking is applied to the blowing louver, generation of mold and adhesion of dust can be prevented and the cost can be reduced.
