Thereafter, a power supply line for supplying power to the heater 120 is inserted into the inlet panel 240 through the wire hole 246 and is connected to the control box 108.

In addition, even when the air conditioner operates in the state where the coupling is completed as described above, the heater 120 or the heat exchanger 140 exchanges heat with the indoor air, but the blocking member 248 blocks the leakage of the heat-exchanged air. .

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

That is, in the embodiment of the present invention, the inlet panel 240 is configured to form the exterior of the left side and the front part of the indoor unit 100, but if necessary, the inlet panel 240 is located in front of the right panel 214, The heater coupling part 217, the heat exchange coupling part 218, and the transmission part 219 formed on the right side panel 214 are formed on the left side panel 212 so that the heater and the heat exchanger 140 are formed on the inlet panel 240 and the left side. Of course, it can also be configured to be fixed to the panel 212.

In the indoor unit of the air conditioner as described in detail above, a heat exchanger and a heater are provided and configured such that the heat exchanger and the heater are simultaneously supported by the inlet panel.

Therefore, there is an advantage in that the heat exchanger and the heater is easy to install and the assemblability is improved.

In addition, the inlet panel is configured to form an inlet to guide the inflow direction of the indoor air.

Therefore, when the heater is installed in the inlet panel, the indoor air heated by the heater may be introduced into the indoor unit in a state in which air leakage is blocked by the inlet panel, thereby improving heat exchange efficiency.
