         8 . An indoor unit of an air conditioner comprising:
 a main body;   a front heat exchanger and a rear heat exchanger disposed in the main body;   an electronic expansion valve disposed in the main body;   a control unit controlling electrical components mounted in the main body;   a control case including a first side surface part disposed between the control unit and the electronic expansion valve and an extension part connected with the first side surface part and extended in the lengthwise direction of the heat exchanger; and   a receipt space provided at the outside in the lengthwise direction of the front heat exchanger,   wherein the receipt space is located above the extension part.   
     
     
         9 . The indoor unit according to  claim 8 , wherein the receipt space is located between the front heat exchanger and the control unit. 
     
     
         10 . The indoor unit according to  claim 8 , wherein the receipt space is located at the outside of the control case. 
     
     
         11 . The indoor unit according to  claim 8 , further comprising a water collector to receive condensed water formed within the main body,
 wherein the extension part includes a guide part downwardly inclined from the first side surface part toward the water collector and a water intake part upwardly inclined from the guide part.   
     
     
         12 . The indoor unit according to  claim 11 , wherein the control case further includes a second side surface part connected with the extension part and downwardly extended and a protruding part connected with the second side surface part and protruded toward the water collector. 
     
     
         13 . The indoor unit according to  claim 8 , wherein the electronic expansion valve includes a driving part in which a rotor is mounted,
 wherein the electronic expansion valve is disposed such that the driving part faces the front surface of the main body.   
     
     
         14 . The indoor unit according to  claim 13 , wherein the electronic expansion valve further includes a passage part, through which a refrigerant flows into and out of the electronic expansion valve, extended from the driving part,
 wherein the driving part is located at a height equal to or higher than the passage part.   
     
     
         15 . An indoor unit of an air conditioner comprising:
