Ceiling-mounted heating and cooling apparatus

Abstract

A ceiling-mounted heating and cooling apparatus is disclosed, which is capable of uniformly heating and cooling an indoor space in such a manner that a discharge air from a heating and cooling apparatus is discharged toward a portion distanced far from an inlet. In a ceiling-mounted heating and cooling apparatus which is installed at a ceiling of a certain building and includes a suction port and a discharge port, there is provided an improved ceiling-mounted heating and cooling apparatus, comprising a duct part which is detachably installed at the discharge port and transfers a discharge air into the lower surfaces of the indoor of the building, wherein said duct part is a bellows or a telescope type unit. The indoor of the building can be uniformly heated or cooled by discharging discharge air further from the suction port of the ceiling-mounted heating and cooling apparatus.

1 . In a ceiling-mounted heating and cooling apparatus which is installed at a ceiling of a certain building and includes a suction port and a discharge port, an improved ceiling-mounted heating and cooling apparatus, comprising: 
 a duct part which is detachably installed at the discharge port and transfers a discharge air into the lower surfaces of the indoor of the building,    wherein said duct part is a bellows or a telescope type unit.    
     
     
         2 . The apparatus of  claim 1 , wherein said duct part includes a guide part which is designed to guide an extension of the same in a longitudinal direction.  
     
     
         3 . The apparatus of  claim 2 , wherein said guide part includes a moving part for extending one end of the duct part, and a driving part which drives the moving part.  
     
     
         4 . The apparatus of  claim 3 , wherein said moving part includes a belt which rotates so as to extend one end of the duct part, and driving and driven pulleys connected between the both ends of the duct part through the belt, and said driving part includes a driving motor which is connected with the driving pulley and is installed on the ceiling for thereby driving the driving pulley, and a switch which is electrically connected so as to normally rotate or reverse-rotate the driving motor.  
     
     
         5 . The apparatus of  claim 1 , wherein said duct part further includes a fan installed at an end of the duct part for thereby efficiently discharging the discharge air.  
     
     
         6 . The apparatus of  claim 1 , wherein said duct part is inclined downwards from the discharge part and gets distanced more and more from the suction port to the outer side.
