The cabinet includes: an upper left protrusion and an upper right protrusion protruding forward from an upper portion of the cabinet; and a lower left protrusion and a lower right protrusion protruding forward from a lower portion of the cabinet, so that the protrusions support the heat exchanger.
1. An indoor unit for an air conditioner, the indoor unit comprising:
a heat exchanger, an inlet, an outlet, an air-blowing fan, a fan motor to drive the air-blowing fan, and a cabinet, wherein
the heat exchanger is placed only in front of a rotation center of the air-blowing fan,
the inlet is provided in rear of the heat exchanger,
the outlet is provided in front of the heat exchanger,
the air-blowing fan blows air, sucked from the inlet, at the heat exchanger, and blows the air out from the outlet,
the cabinet includes: an upper protrusion protruding forward from an upper portion of the cabinet; and a lower protrusion protruding forward from a lower portion of the cabinet, the upper protrusion and the lower protrusion supporting the heat exchanger,
the air-blowing fan and the fan motor are placed below the upper protrusion of the cabinet and above the lower protrusion of the cabinet,
the lower protrusion includes a lower left protrusion and a lower right protrusion respectively provided on a left side and a right side of the cabinet, and
an opening is formed that allows at least the fan motor to be taken out downward between the lower left protrusion and the lower right protrusion while the heat exchanger is supported by the lower left protrusion and the lower right protrusion.
2. The indoor unit according to claim 1 , wherein
the air-blowing fan includes a plurality of air-blowing fans horizontally arranged in the cabinet, and, between the plurality of air-blowing fans, a motor accommodation is provided to accommodate the fan motor to rotate the plurality of air-blowing fans.
3. The indoor unit according to claim 1 , wherein
the lower protrusion further includes a lower middle protrusion provided removably between the lower left protrusion and the lower right protrusion.
