FIG. 5 is a sectional view showing a conventional ceiling-embedded air conditioner disclosed in, for example, Japanese Patent Laid-Open No. 60-78242. In the figure, a box-shaped cabinet 51 is embedded in a ceiling hole 53 provided in a ceiling 52. 54 is a heat exchanger, which is connected to the cabinet 51;
It is attached to the inner ceiling part with a space between it and the inner part. A multi-blade blower 55 is attached to the bottom of the heat exchanger 54. Reference numeral 56 denotes a partition plate, one opening of which is attached to the bottom of the heat exchanger 54 via the attachment part of the blower 55, and the other opening serving as a suction port 56i. This partition plate 56 and the cabinet 51
As a result, a blowout duct 57 is formed, and its indoor opening is set as a blowout port 57o. 58 is a louver that connects the ceiling hole 53, that is, the suction port 56i.
and the suction port 56 so as to cover the air outlet 57o.
It is attached to i.

介して室内側に吹き出される。 Since the conventional ceiling-embedded air conditioner is configured as described above, indoor air is supplied from the center of the louver 58 to the suction port 56i by the blower 55.
and is sent to the heat exchanger 54 through the blower 55. After heat exchange in the heat exchanger 54, the air is guided to the blow-off duct 57 and is blown out to the indoor side via the blow-off port 57o and the periphery of the louver 58.
第６図にこの従来の天井埋込形空気調和機によ
る室内側気流の一例を矢印により示す。 FIG. 6 shows an example of the indoor airflow caused by this conventional ceiling-embedded air conditioner by arrows.

がある。
Since the conventional ceiling-embedded air conditioner has the suction port 56i and the air outlet 57o adjacent to each other as described above, the air blown out from the air outlet 57o is immediately sucked in from the adjacent suction port 56i. There is a problem in that a "short cycle" occurs and cooling or heating is not performed efficiently.
前記シヨートサイクルは、ルーバ５８の吹出し
方向を下方に向けて床面まで風を到達させようと
する暖房運転時に発生し易い。 The short cycle is likely to occur during a heating operation in which the blowing direction of the louver 58 is directed downward to allow air to reach the floor surface.
前述のような問題点を解決するものとしては、
前記吹出しダクト５７を延長してその先端に吹出
し口を設けるものが提案されている。このような
構成にすれば、吹出し口と吸込み口とが充分に離
間されるため、シヨートサイクルの発生を防止で
きるが、新たに延長用ダクトが必要になる。 To solve the problems mentioned above,
It has been proposed to extend the air duct 57 and provide an air outlet at its tip. With such a configuration, the outlet and the suction port are sufficiently spaced apart from each other, so that the occurrence of a shoot cycle can be prevented, but an additional duct for extension is required.

問題点がある。 Furthermore, in the conventional ceiling-embedded air conditioner, the air sucked in from the central suction port 56i is passed through the heat exchanger 54 provided between the blower 55 and the blow-off duct 57, and then passed through the blow-off duct 57. Since the air is blown out from the outlet 57o provided at the periphery of the louver, there are problems in that the air passage structure is complicated, the air passage resistance is large, and the noise caused by the air passage is large.

FIG. 1 shows a "ceiling-mounted air conditioner" which is an embodiment of this invention. In the figure, 1 is the ceiling 2
A box-shaped cabinet (main body) embedded in a ceiling hole (first ceiling opening) 3 provided in the cabinet 1;
6 is an axial blower attached to the center of the ceiling of the cabinet 1; 6 is an axial blower 5 and the second axial blower;
7 is a bell mouth attached to the bottom of the heat exchanger 6; 8 is a decorative panel (louver) attached to the bell mouth 7 and having an outlet on the periphery; , 9 is a first suction port (second ceiling opening) which is provided in the ceiling 2 apart from the ceiling hole 3 and sucks indoor air into the attic.

行われた後、直下に吹き出され、ついで、ルーバ
８の傾き方向に沿つて室内側に吹き出される。 Since the ceiling-embedded air conditioner of this embodiment is configured as described above, the indoor air is sucked into the attic space through the first suction port 9 by the axial blower 5, and then into the attic space through the second suction port 9. It is sent from the port 4 to the heat exchanger 6. After heat exchange is performed by the heat exchanger 6, the air is blown out directly below, and then blown out toward the indoor side along the direction of inclination of the louver 8.

は冷房し、その後、再び、第１の吸込み口９から
天井裏に吸い込まれる。 The air blown into the room heats or cools the room, and is then sucked into the attic again through the first suction port 9.
第２図にこの実施例による室内側および天井裏
の気流の一例を示す。 FIG. 2 shows an example of the airflow inside the room and under the ceiling according to this embodiment.
また、この実施例の天井埋込形空気調和機は、
第１の吸込み口９を天井孔３から離間して配設
し、天井裏を風路の一部にする構成にしたから、
キヤビネツト１内の風路は簡単になり、また風路
断面を大きくできるので、風路に起因する騒音が
軽減される。 In addition, the ceiling-embedded air conditioner of this example is
Since the first suction port 9 is arranged at a distance from the ceiling hole 3, and the attic is made a part of the air passage,
The air passage inside the cabinet 1 is simplified and the cross section of the air passage can be increased, so noise caused by the air passage is reduced.
送風機の騒音特性が同じレベルを有する場合、
騒音低下量ΔSPL.は、式(1)で表わされ、
ΔSPL.＝251og（P2／P1）……(1)
但、P1，P2は送風機の動作圧力
例えば圧力損失が30％低下すると、約4dBの騒
音低下となる。 If the noise characteristics of the blower have the same level,
The amount of noise reduction ΔSPL. is expressed by the formula (1), ΔSPL.=251og (P2/P1)...(1) However, P1 and P2 are the operating pressures of the blower. For example, if the pressure loss decreases by 30%, approximately This results in a 4dB noise reduction.
なお、天井埋込形空気調和機を前述のように構
成しても、天井裏の熱負荷は、中間階では特に問
題になることはない。 Note that even if the ceiling-embedded air conditioner is configured as described above, the heat load in the attic does not pose a particular problem on intermediate floors.

As explained above, according to this invention, the suction port can be disposed at a sufficient distance from the blowout port, so short cycles can be prevented, and therefore, cooling and heating efficiency can be improved. Furthermore, since the attic itself is part of the air passage, the air passage within the main body is simplified, the cross section of the air passage can be increased, and noise caused by the air passage can be reduced. Furthermore, since most of the air outlet is covered with a decorative panel, no noise is directly emitted from the blower into the room.
