An end plate 5 is attached to the end plate 3 of the main heat exchanger 1 with screws 4 or the like. 6 is a frame for fixing the main heat exchanger 1 and the like, 7 is a front frame constituting the exterior of the air conditioner, 8 is a suction panel constituting the exterior, and 9 is a mounting frame for an air cleaner, etc. The end plate 5 of the vessel 2 is fixed to the opposite side of the main heat exchanger 1.
[0004]
The air conditioner to which this type of air purifier mounting frame 9 is attached is provided with an auxiliary space in order to ensure a gap 10 provided between the auxiliary heat exchanger 2 and the main heat exchanger 1 so as not to generate vibration noise. When the heat exchanger 2 is not installed, a dedicated end plate (not shown) separate from the end plate 5 of the auxiliary heat exchanger 2 is disposed, and the mounting frame 9 is attached to the air cleaner and the main heat. A gap was formed between the exchangers.
[0005]
However, when the auxiliary heat exchanger 2 is not mounted in the above-described conventional configuration, an end plate, which is a part unrelated to the functions of the air conditioner and the air purifier, is originally disposed, resulting in increased assembly man-hours and material costs. In addition, since the attachment frame 9 such as an air purifier is attached only by the end plate, there is a problem that the attachment is unstable.
