The internal structure of the integrated air conditioner described above is
As shown in FIG. 2, the base 1 is divided into front and rear by a partition plate 4 which is erected on the base 1, and the divided front portion is the indoor side 2 and the divided rear portion is the outdoor side 3. They are provided respectively. On the indoor side 2, an indoor heat exchanger 11 placed on a dew tray 12 and provided to face the suction port 7 of the front panel 6 and a front surface of the partition plate 4, which will be described later. An accommodating portion 15a for accommodating the centrifugal fan and an outlet passage 15b connected to the air outlet 8 of the front panel 6 are provided, and a fan casing 15 made of styrofoam material having an open front and upper surfaces is provided. A cylindrical centrifugal fan 14 that is housed in the housing portion 15a and is rotatably supported by one of the rotation shafts of a fan motor that is mounted on the back surface of the partition plate 4 and that has a number of blades on its circumference. The fan casing 15 is provided with a suction hole 13a for guiding the air heat-exchanged in the indoor heat exchanger 11 to the fan casing 15, and is fixed to the partition plate 4 and the base 1.
1, a seal plate 13 for covering the opened front surface of the fan casing, a fan casing cover 19 made of foam material for covering the opened upper surface of the fan casing, and a wind shield plate 20 made of sheet metal are respectively provided.

On the outdoor side 3, the outdoor heat exchanger 16 facing the air outlet provided on the back surface 10, the indoor heat exchanger 11 and the outdoor heat exchanger 16 are connected by piping to form a refrigeration circuit. A compressor 17 and a propeller fan 18 that is rotatably supported by the other of the rotation shafts of the fan motor and discharges the air that has been heat-exchanged by the outdoor heat exchanger 16 to the outside.

The indoor air sucked from the suction port 7 of the front panel 6 is cooled by the indoor heat exchanger 11 to condense the moisture contained on the surface thereof, while being provided in the seal plate 13. It flows into the fan casing 15 through the suction hole 13a, passes through the blowout passage 15b formed in the fan casing 15 by the centrifugal fan 14, and again from the blowout port 8 formed in the front panel 6. It is designed to be sent indoors,
Condensed water condensed on the surface of the indoor heat exchanger 11 is dropped on the dew tray 12 and is stored and then discharged to the outside. The outdoor air sucked from the outdoor suction port 5a formed in the outer case 5 is heat-exchanged by the outdoor heat exchanger 16, and the outdoor air is discharged from the air outlet provided on the rear surface 10 by the propeller fan. It is supposed to be released.

Next, the blower fan 14 is housed in the housing portion 15a of the fan casing 15 and is pivotally supported by the rotation shaft of the fan motor. Subsequently, the seal plate 13 is arranged on the front surface of the fan casing 15, and one side of the partition plate 4 is provided.
The other side is fixed to the base 1. As a result, the fan casing 15 is sandwiched between the partition plate 4 and the seal plate 13, while the cut-and-raised piece 13d bites into the front surface 15c of the accommodating portion 15a, and the fan casing 15 and the seal. The board 13 and the board 13 are shielded.

As described above, the cut-and-raised piece 13d bites into the front surface of the fan casing 15 and shields the space between the cut-and-raised piece 13d and the seal plate 13, so that the seal plate 1
The air that is not heat-exchanged through the gap between the fan casing 3 and the fan casing 15 can be prevented from entering the accommodation portion 15a and being mixed with the heat-exchanged air, while eliminating the need for a separately manufactured wind shield. In addition, the assembling work can be easily performed.

Next, another embodiment will be described. Figure 4
In the embodiment shown by (1), a triangular cut-and-raised piece 22 is formed on the seal plate 21, and the tip end portion of the cut-and-raised piece 22 is bent, and when it is pressed against the front surface of the fan casing 15, As it bites, the seal plate 21
The adhesion of the fan casing 15 to the fan casing 15 is improved.
