Description

[Detailed explanation of the idea] The present invention relates to a ceiling-embedded air conditioner.

An example of a conventional air conditioner of this kind is shown in FIG. 1, in which a cabinet 1 is embedded in a ceiling 2 and supported by a hanging fitting 11 and a hanging rod 12 on a beam (not shown). Reference numeral 3 denotes a panel which is attached to the ceiling 2 and has an air suction port 4 provided at its center and an air outlet 5 provided around it. Indoor air that is sucked in from the air suction port 4 by the blower 7 driven by the electric motor 8 and rises is cooled or heated by exchanging heat there as it passes through the heat exchanger 6, and then descends inside the rear side plate 1a. The air is blown into the room from the air outlet 5. A support plate 10 for supporting the heat exchanger 6, blower 7, electric motor 8, and drain pan 9 is attached to the side plate 1a of the cabinet 1 with tightening screws 13.

In this air conditioner, since the support plate 10 is connected to the side plate 1a, the connecting member blocks the air flow path within the cabinet 1.
Since the amount of air blown out from each outlet 15 is non-uniform, it has been difficult to blow out air uniformly over the entire circumference of the panel 3. Furthermore, since the side plate 1a bears the load of the parts inside the cabinet 1, it is necessary to use a rigid material for the side plate 1a. Furthermore, inspection, repair, and attachment/detachment of parts inside the cabinet 1 from the bottom surface had to be done in the corners of the machine, making these operations difficult.

The present invention was proposed to address the above problems, and its gist is that the device is embedded in the ceiling and heat exchanges indoor air sucked in by a blower from the air intake port at the center of the bottom surface. In a ceiling-embedded air conditioner that blows out the air from the air outlet around the air inlet into the room after passing through the air inlet, at least the blower, the electric motor that drives it, the heat exchanger, and the drain that will drip from it are A ceiling-embedded air conditioner is characterized in that a receiving drain pan is suspended from the center of the top plate of the cabinet.

In this invention, at least heavy parts such as the blower, electric motor, heat exchanger, and drain pan are suspended from the top plate of the cabinet, so no load is applied to the side plate, and therefore the side plate has a wind blocking function. Since it is enough to play, that rigidity is not necessary. and,
Since the blower, electric motor, heat exchanger, drain pan, etc. are suspended from the center of the top plate of the cabinet, the air flow path is not blocked by the connecting member between these parts and the side plate. Therefore, the air that has passed through the heat exchanger smoothly descends along the inside of the side plate,
Air is blown out evenly and evenly from each outlet.
The blower, electric motor, heat exchanger, and drain pan can be inspected, repaired, and installed or removed from the center of the bottom surface of the cabinet, making it easy to perform these tasks.

An embodiment of the present invention is shown in FIG. 2, in which a motor 8 with a blower 7 attached to the center of the top plate 1b of the cabinet 1 is tightened with a tightening screw 14.
A heat exchanger support plate 15 that supports the heat exchanger 6 is fixed around the heat exchanger with tightening screws 16 . Top plate 1b
The support rod 17, whose upper end is fixed to the drain pan 9, passes through a through hole 18 provided in the drain pan 9 and a hole provided in the support plate 10, and is attached to the support plate by screwing a nut 20 into a screw 19 provided at the tip thereof. 10 and the drain pan 9 are suspended. The rest of the structure is the same as the conventional one shown in FIG. 1, and corresponding members are given the same reference numerals.

Therefore, the blower 7, the electric motor 8, the heat exchanger 6,
The drain pan 9 and the support plate 10 are suspended from the center of the top plate 1b of the cabinet 1, and these parts and the side plate 1
Since there is no connection between air inlet 4 and
The air sucked in by the blower 7 rises, passes through the heat exchanger 6, descends inside the rear side plate 1a where it has been heat exchanged, and flows unevenly to the air outlet 5 provided around the air inlet 4. It reaches the room without any problems and is blown out into the room. Moreover, since the load of these parts is not applied to the side plate 1a, it only needs to have a wind-shielding effect.

In this way, it is possible to blow out air evenly from the air outlet 5, and good air conditioning of the room can be achieved. Further, since only the top plate 1b needs to have rigidity, the side plate 1a is simplified and the weight of the machine is reduced. And a blower 7, an electric motor 8, a heat exchanger 6,
Inspection, repair, and attachment/detachment of the drain pan 9 and the like can be performed from the center of the bottom surface, and these operations can be easily performed.
