The present invention relates to a ceiling cassette air conditioner having good design properties.
BACKGROUND ARTConventionally, there is a ceiling cassette air conditioner that takes in air from a room, and supplies conditioned air into the room. This ceiling cassette air conditioner has four wind direction vanes to adjust blowing directions. The blowing directions toward the room are adjusted by adjusting angles of these wind direction vanes. Further, in this ceiling cassette air conditioner, four wind direction vanes and a decorative panel are flush with a ceiling surface when the ceiling cassette air conditioner is out of operation in order to improve design properties.
CITATION LIST Patent LiteraturePatent Literature 1: Japanese Unexamined Patent Application Publication No. 2012-107864
SUMMARY OF INVENTION Technical ProblemHowever, in operation, each of the four wind direction vanes is fixed at a predetermined angle or is moving to adjust the blowing direction. Therefore, the wind direction vanes which are fixed at predetermined angles or moving are recognized by a user visually. As a result, the design properties are deteriorated.
The present invention is made in order to solve the above-mentioned problem, and it is therefore an object of the present invention to provide a ceiling cassette air conditioner with which deterioration in design properties during operation due to wind direction vanes is reduced.
Solution to ProblemA ceiling cassette air conditioner according to the present invention includes: a main body arranged in a ceiling and having a rectangular cross-section opening on a room side of the main body; a blower fan arranged in the main body, and configured to blow air taken in from an air inlet of the main body to a discharge outlet of the main body; a heat exchanger arranged in the main body and downstream of the blower fan, and configured to exchange heat with the air taken in from the air inlet; a decorative panel covering the opening, and arranged to be flush with a ceiling surface; and a wind direction vane arranged in the discharge outlet, and configured to adjust a blowing direction. The wind direction vane is arranged behind the decorative panel.
Advantageous Effects of InventionIn the ceiling cassette air conditioner according to the present invention, because the wind direction vanes in the discharge outlet are arranged behind the decorative panel, a user in a room cannot visually recognize the wind direction vanes. Therefore, even when the ceiling cassette air conditioner is in operation and each of four wind direction vanes is fixed at a predetermined angle or moving, a user cannot visually recognize the wind direction vanes, and as a result, an effect of avoiding deterioration of design properties can be achieved.

When the lifting device 9 moves the peripheral panel 10 toward the room side, a gap is formed between the peripheral panel 10 and the central panel 11. This gap functions as the air inlet 12 of the ceiling cassette air conditioner 1. Similarly, when the peripheral panel 10 is moved toward the room side, a gap is formed between the peripheral panel 10 and the exterior case 4. This gap functions as the discharge outlet 13 of the ceiling cassette air conditioner 1. That is, when the ceiling cassette air conditioner 1 is out of operation, the exterior case 4, the peripheral panel 10, and the central panel 11 are flush with the ceiling surface 3 and are arranged in such a way that gaps are not formed as shown in
When the ceiling cassette air conditioner 1 starts its operation, the air in the room is taken in into the main body 2 via the air inlet 12. Then, the air taken in into the main body 2 is conditioned as sequentially passing through the dust collection filter 7, the blower fan 5, and the heat exchanger 6. After that, the air is discharged from the discharge outlet 13 into the room.

Further, a moving amount, that is, a lowering amount of the peripheral panel 10 toward the room side by the lifting device 9 may be changed depending on the blowing directions of the air toward the room. As shown in
As other variations, the lowering amount of the peripheral panel 10 by the lifting device 9 may be changed depending on a blowing amount of the air supplied into the room. For example,
In the ceiling cassette air conditioner according to Embodiment 1, since the wind direction vanes in the discharge outlet are arranged behind the decorative panel, the wind direction vanes cannot be recognized by a user visually. Therefore, even though four wind direction vanes are fixed at predetermined directions or are moving respectively during an operation, they are not visually recognized by a user. As a result, an effect proper to the present invention of avoiding deterioration of design properties can be achieved.
Embodiment 2In Embodiment 1, the central panel of the ceiling cassette air conditioner is a plate having a rectangular shape, the peripheral panel and the central panel are provided separately, and they are separated from each other during operation. On the other hand, a central panel of a ceiling cassette air conditioner according to Embodiment 2 has a rectangular shape with a grating structure, and the peripheral panel and the central panel are formed as an integrated member.

When the lifting device 9 moves the decorative panel 17 toward the room side, a gap is formed between the peripheral panel 16 and the exterior case 4. This gap functions as the discharge outlet 13 of the ceiling cassette air conditioner 1. That is, when the ceiling cassette air conditioner 1 is out of operation, the exterior case 4, the peripheral panel 16, and the central panel 15 are flush with the ceiling surface 3 and are arranged in such a way that a gap is not formed as shown in
When the ceiling cassette air conditioner 1 starts its operation, the air in the room is taken in into the main body 2 via the air inlet 18. Then, the air taken in into the main body 2 is conditioned as sequentially passing through the dust collection filter 7, the blower fan 5, and the heat exchanger 6. After that, the air is discharged from the discharge outlet 13 into the room.
As described above, in the ceiling cassette air conditioner according to Embodiment 2, the peripheral panel and the central panel are integrally moved during operation. Thus, a step is not formed between the peripheral panel and the central panel. Therefore, in addition to the effects according to Embodiment 1, an effect of further improving the design properties is achieved.
