のとなっている。Therefore, the conventional ceiling-hung air conditioner has a coarse dust filter,
Since the medium performance filter, the blower, and the heat exchanger are arranged in this order, in order to perform maintenance and inspection of the inside, particularly the blower, an inspection port 9 of a size as necessary is provided in the casing K,
Moreover, it is installed near the blower installation. Therefore, it takes a lot of time to install the inspection port, and in some cases, the inspection port spoils the appearance. Furthermore, since the air that has undergone heat exchange in the heat exchanger is directly discharged from the discharge port, the noise caused by the blower and the noise when passing through the heat exchanger are not attenuated and are discharged directly into the room. The noise is also significant.
【0004】本発明は点検口を省き、吸込口側から点検

図ることができる。[Operation] Since the coarse dust filter, the blower, the heat exchanger, and the medium performance filter are arranged in this order from the suction port side in the required air flow direction, an inspection port is provided in the casing. Even if it is not necessary, by removing a simple coarse dust filter, maintenance and inspection of the blower etc. can be easily performed from the suction port side. Furthermore, since a medium-performance filter is installed between the heat exchanger and the discharge port, this medium-performance filter acts as a sound deadening material, and noise from the blower or noise when air passes through the heat exchanger, etc. Is reduced, and the noise leaking into the room becomes a lower value than the conventional one, and the noise can be reduced.

うになす。The casing K has a suction port 8 at one end.
, And a discharge port 7 is provided at the other end, and a required coarse dust filter 5 is arranged in the vicinity of the suction port 8 inside thereof, whereby the air sucked into the casing K from the suction port 8 is provided. Is filtered by the coarse dust filter 5 to remove coarse dust and the like in the intake air, and then the filtered air is circulated in the casing K to reach the blower 2. Therefore, when the blower 2 is rotated by the motor 3, the inside of the suction side of the blower has a negative pressure, so that the atmosphere or room air is sucked into the casing from the suction port.

換器内を通過する際、所望の熱交換が行われる。A baffle plate 6 is provided on the downstream side of the blower 2, and the air blown by the blower is applied to the baffle plate 6 so that the air is evenly sent to the heat exchanger 1 provided on the downstream side. Eggplant When the air blown from the blower uniformly passes through the heat exchanger, desired heat exchange is performed.

A medium-performance filter 4 having fine eyes is provided, and after being filtered by the medium-performance filter 4, the medium is discharged from the discharge port 7 into the room.

る。A drain pan 10 is provided at the inner bottom portion between the heat exchanger 1 and the medium-performance filter 4, and in the heat exchanger,
Alternatively, a condensed water draining means for collecting condensed water immediately after passing through the heat exchanger and discharging it from the drain to the outside of the casing is provided.

り送風機の脱着保守点検が直接行えるものとなる。Therefore, in the air conditioner configured as described above, only the coarse dust filter is installed between the blower and the suction port on the suction port side, and therefore, compared with the conventional medium performance filter and the coarse dust filter integrated type. Since the structure and installation of the coarse dust filter alone are simple, removal and maintenance of the blower can be performed directly from the large suction port by removing the coarse dust filter without providing a separate inspection port.

伝搬する騒音を低減できるものとなる。Further, since the medium performance filter 4 is arranged between the heat exchanger 1 and the discharge port 7, the discharge noise from the blower is finer than that of the coarse dust filter and the medium performance filter is thicker. When passing through, the noise is attenuated to that extent, and the noise propagating into the room through the duct from the discharge port or the discharge port can be reduced.

され、低騒音化を図れる等の利点を有する。According to the ceiling suspension concealing compact air conditioner of the present invention, a coarse dust filter, a blower, a heat exchanger, and a medium performance filter are arranged in the required casing in the flow direction of the air flow from the suction port side. Since the conventional inspection port provided in the casing is no longer required, maintenance and inspection / removal of the blower etc. from the suction port can be performed, and work from the suction port with a large opening can be done easily. The property is improved. Further, since the medium-performance filter is provided between the heat exchanger and the discharge port, it has an advantage that it absorbs the noise of the blower and the like, is attenuated, and the noise can be reduced.
