Indoor unit of air conditioner

Abstract

An indoor unit of an air conditioner is disclosed. The air conditioner is an apparatus that cools or heats an indoor space by circulating refrigerant in one direction or another. The indoor unit of the air conditioner comprises a case spaced apart from the ceiling of a room by a predetermined distance, an indoor heat exchanger provided in the case to heat or cool the room, and a fan and fan motor provided in the case to suction and discharge air.

1 . An indoor unit of an air conditioner comprising: 
 a case spaced apart from the ceiling of a room by a predetermined distance;    an indoor heat exchanger provided in the case and adapted to cool or heat the room; and    a fan and fan motor provided in the case and adapted to suction and discharge air.    
     
     
         2 . The indoor unit as set forth in  claim 1 , further comprising: 
 refrigerant pipes connected to the case for the supply of refrigerant.    
     
     
         3 . The indoor unit as set forth in  claim 2 , further comprising: 
 a drain pipe to discharge condensate water, that is produced as the air passes through the indoor heat exchanger, to the outside of the indoor unit.    
     
     
         4 . The indoor unit as set forth in  claim 3 , wherein the drain pipe is configured to discharge the produced condensate water to the outside of the room.  
     
     
         5 . The indoor unit as set forth in  claim 3 , wherein the drain pipe is configured to discharge the produced condensate water to a predetermined position of the room.  
     
     
         6 . The indoor unit as set forth in  claim 1 , wherein a fixing line is provided between the case and the ceiling, and is adapted to support the case at a predetermined position spaced apart from the ceiling by the predetermined distance.  
     
     
         7 . The indoor unit as set forth in  claim 6 , wherein a first mount is mounted at an upper end of the case, and the lower end of the fixing line is affixed to the first mount.  
     
     
         8 . The indoor unit as set forth in  claim 7 , wherein a control circuit unit is provided in the first mount to control operation of the air conditioner.  
     
     
         9 . The indoor unit as set forth in  claim 6 , wherein a second mount is mounted at the ceiling, and the upper end of the fixing line is affixed to the second mount.  
     
     
         10 . The indoor unit as set forth in  claim 2 , the refrigerant pipes are made of a flexible material.  
     
     
         11 . The indoor unit as set forth in  claim 3 , the drain pipe is made of a flexible material.  
     
     
         12 . The indoor unit as set forth in  claim 3 , further comprising a pipe cover configured to enclose the refrigerant pipes and the drain pipe to prevent the pipes from being exposed to the outside.  
     
     
         13 . The indoor unit as set forth in  claim 12 , wherein the pipe cover is configured to enclose each of the refrigerant pipes and the drain pipe separately.  
     
     
         14 . The indoor unit as set forth in  claim 12 , wherein the pipe cover is configured to enclose the refrigerant pipes and the drain pipe together.  
     
     
         15 . The indoor unit as set forth in  claim 12 , wherein the pipe cover is made of a flexible material.  
     
     
         16 . The indoor unit as set forth in  claim 1 , wherein the indoor heat exchanger and an expander are arranged in an upper portion of the case, and the fan and the fan motor are arranged in a lower portion of the case.  
     
     
         17 . The indoor unit as set forth in  claim 1 , wherein the fan and the fan motor are arranged in an upper portion of the case, and the indoor heat exchanger and an expander are arranged in a lower portion of the case.  
     
     
         18 . The indoor unit as set forth in  claim 1 , wherein a drain pump is provided in the case to discharge condensate water, that is produced by the indoor heat exchanger, to the outside of the indoor unit via the drain pipe.  
     
     
         19 . An indoor unit of an air conditioner comprising: 
 a case containing a fan motor and indoor heat exchanger therein and spaced apart from the ceiling of a room by a predetermined distance;    refrigerant pipes extended from an outside place to the case;    a fixing line provided between the case and the ceiling and adapted to support the case at a predetermined position spaced apart from the ceiling by the predetermined distance; and    a condensate water sump to store the condensate water that is produced as air passes through the indoor heat exchanger.
