Indoor unit of air-conditioning apparatus

Abstract

An object of the invention is to provide an indoor unit of an air-conditioning apparatus, which facilitates a change of the position from which a pipe is taken out. A heat exchanger unit is inverted back to front in a state in which the relationship between the bottom surface and the upper surface of the heat exchanger unit is maintained, so that a pair of opening portions can be selectively connected to an air outlet of an air-sending unit. The air-sending unit is inverted upside down so that an air outlet can be connected to a selected opening portion from among the pair of opening portions of the heat exchanger unit.

What is claimed is: 
     
         1 . An indoor unit of an air-conditioning apparatus, comprising:
 an air-sending unit having an air inlet and an air outlet and having an air-sending device accommodated therein; and   a heat exchanger unit having a pair of opening portions formed at opposite positions and having an indoor side heat exchanger accommodated therein,   wherein the heat exchanger unit is inverted back to front in such a manner that a relationship between a bottom surface and an upper surface of the heat exchanger unit is maintained, with the result that the pair of opening portions can be selectively connected to the air outlet of the air-sending unit, and   the air-sending unit is inverted upside down in such a manner that the air outlet can be connected to an opening portion selected from the pair of opening portions of the heat exchanger unit.   
     
     
         2 . The indoor unit of an air-conditioning apparatus of  claim 1 , wherein the air-sending unit is provided with first suspension metal fittings on an upper surface side and a lower surface side of the air-sending unit, the first suspension metal fittings being used when the air-sending unit is installed, and
 the heat exchanger unit is provided with second suspension metal fittings on the side of end portions at which the pair of opening portions are formed, the second suspension metal fittings being used when the heat exchanger unit is installed.   
     
     
         3 . The indoor unit of an air-conditioning apparatus of  claim 1 , wherein the indoor side heat exchanger is installed so as to slope down from the side of one of the opening portions of the heat exchanger unit to the side of the other opening portion. 
     
     
         4 . The indoor unit of an air-conditioning apparatus of  claim 3 , wherein the heat exchanger unit includes a drain pan provided at a lower side of the indoor side heat exchanger, so as to support one end side of the indoor side heat exchanger. 
     
     
         5 . The indoor unit of an air-conditioning apparatus of  claim 4 , wherein the drain pan includes a first slope surface and a second slope surface, the first slope surface being formed at a position where the drain pan comes into contact with the indoor unit heat exchanger, the second slope surface being formed on the side opposite to the first slope surface, and
 wherein the first slope surface and the second slope surface respectively slope down in a direction in which the indoor side heat exchanger slopes down, and in a direction opposite thereto.   
     
     
         6 . The indoor side of an air-conditioning apparatus of  claim 5 , further comprising:
 an air outlet portion being capable of separating and formed in an opening portion serving as an air outlet, from among the pair of opening portions which are formed in the heat exchanger unit,   wherein the air outlet portion is configured such that the side thereof at the upper side of a slope surface having a higher vertical position from among the first slope surface and the second slope surface of the drain pan is open and that the side thereof at the lower side of the slope surface having a higher vertical position from among the first slope surface and the second slope surface of the drain pan is blocked.   
     
     
         7 . The indoor unit of an air-conditioning apparatus of  claim 1 , wherein the air-sending unit comprise an electrical component box on a side face of the air-sending unit, the electrical component box controlling the air-sending device. 
     
     
         8 . An indoor unit of an air-conditioning apparatus, comprising:
 a first unit in which an air-sending device is accommodated; and   a second unit in which a heat exchanger is accommodated,   the second unit including   an air passage through air brown from the air-sending device passes,   a heat exchanger comprised of a plurality of fins and a refrigerant passage,   a part of a refrigerant pipe used to circulate a refrigerant between the heat exchanger and an external equipment, and   a drain pan that catches dew condensation water generated in the heat exchanger and dropping therefrom,   wherein the heat exchanger is disposed so as to slope down with respect to the flow of air, and connects the first unit and the second unit to each other in such a manner that the second unit can be inverted back to front and the first unit can be inverted upside down.
