It stores the box (10). Also,
On the front of the machine room (4), there is a grill (13) with a suction port (11) and a front air outlet (12), and the overhanging piece (15A) of the front upper frame (14) and the front lower frame (15). It is supported between two ends of the rear side upper frame (16) and the rear side lower frame (17), which are screwed at one end to the side surface of the machine room (4) to the outside surface of the heat insulation box (3). The side plate (18) is installed, and the rear side of the machine room (4) has a large number of rear air outlets (19) perforated and one side is screwed to the back side of the heat insulation box (3). , The rear face plate (20), in which the other side portion is screwed to the back side bending flange (18A) of the side face plate (18),
Further, the upper surface and the upper outer peripheral surface of the heat insulating box (3) and the machine room (4) are covered with a top table (21) having a downward peripheral surface flange (21A).

Thus, the rear lower frame (17) for supporting the condensing unit has a rear surface which is substantially flush with the rear surface of the heat insulation box (3), and the rear side lower frame (17) is located on the rear side plate (18). A recess (22) is formed in the part. A pair of left and right rails (23) are placed between the rear lower frame (17) and the upper surface of the front lower frame (15).
Is fixed, and the base (24) on which the condensing unit is attached is mounted so as to be drawn out.

Further, the rear face plate (20) is bent inward in the entire vertical direction including the rear outlet (19) to form a concave passage (25) communicating with the recess (22), and the concave passage (25) Corresponding top table (21)
A notch (26) is formed in the rear flange (21B) of the.

In the above configuration, the power cord (27) extending from the electrical equipment box (10) is inserted through the rear face plate (20) at a portion defining the concave passage (25), passes through the concave passage (25), and An external plug with a plug (27A) attached to the tip of the power cord (27) embedded in the wall surface (28) that is pulled out through the recess (22) formed in the rear surface of the lower frame (17) to the bottom of the product. Connect to power supply (29).

This allows the power cord (27) to be attached to the back of the product and the wall (28) when the product's back is installed in close contact with the wall (28).
There is no need to be pinched in between and therefore the power cord
It is possible to avoid the diagonal installation of the product due to the narrowing of (27).

Furthermore, when the product is installed in close contact with the wall surface (28), the hot air in the machine room (4) is blown out from the rear outlet (19) in the portion defining the concave passage (25), and the concave passage (25 ) And further through the recesses (22) below the product. As a result, the function of the rear outlet (19) is not impaired even in such an installed state.
