That is, by the partition 40, the interior of the outdoor unit 10 is an air blowing area in which the fan motor assembly is installed, and an apparatus area in which various devices for the refrigerant flow except the heat exchanger 25 are installed. Compartment.
The control box 60 is seated on the top of the partition 40. In more detail, a support part 42 (see FIG. 3) to be described later is provided at an upper end of the partition part 40, and the control box 60 is seated on the support part 42. One side of the control box 60 is combined with a control panel 62 for fixing various wires connected to the control box 60.
The outer case 50 includes a front case 51 forming a front exterior, a pipe side case 53 for shielding the refrigerant pipe 27, and a heat exchanger side surface for shielding the side surface of the heat exchanger 25. A case 54, an upper case 55 for shielding the upper surface, and a base fan 31 for supporting various devices and fan motor assemblies for the refrigerant flow.
In more detail, the front case 51 is provided with a discharge grill 52 for discharging the air heat exchanged through the heat exchanger 25. The discharge grill 52 is formed in a circular shape equal to or larger than the fan 31 when viewed from the front. In addition, the discharge grill 52 has a plurality of discharge ports are formed in the shape of a net.
