Ceiling-embedded air conditioner

Abstract

An air passage has a blow-out side opening opposed to a position other than the longitudinal ends of a blow-out port of a decorative panel. The width of a louver, as determined in an air-blowing direction, decreases from a longitudinal center of the louver to the ends of the louver.

1 . A ceiling-embedded air conditioner comprising:
 a casing in which a heat exchange unit and an air blower are arranged;   a decorative panel located on a lower side of the casing and including a suction port and a rectangular blow-out port;   a rectangular louver rotatably provided inside the blow-out port and configured to change a blowing direction in which air is blown out from the blow-out port; and   an air passage comprising a rectangular cross section and configured to guide indoor air, drawn in from the suction port by rotation of the air blower, to the heat exchange unit for heat exchange, and then guide the indoor air to the blow-out port,   the air passage comprising a blow-out side opening opposed to a position other than longitudinal ends of the blow-out port,   a width of the louver, as determined in the blowing direction, decreases from a longitudinal center of the louver to ends of the louver.   
     
     
         2 . The ceiling-embedded air conditioner according to  claim 1 , wherein at least a downstream portion of the louver with respect to the blowing direction is projected downward from the blow-out port when the louver changes the blowing direction of the air to a horizontal direction. 
     
     
         3 . The ceiling-embedded air conditioner according to  claim 1 , wherein the suction port is provided in a central portion of the decorative panel, and the blow-out port is provided at four positions surrounding the suction port. 
     
     
         4 . A ceiling-embedded air conditioner comprising:
 a casing in which a heat exchange unit and an air blower are arranged;   a decorative panel located on a lower side of the casing and including a suction port and a rectangular blow-out port;   a rectangular louver rotatably provided inside the blow-out port and configured to change a blowing direction in which air is blown out from the blow-out port;   an air passage comprising a rectangular cross section and configured to guide indoor air, drawn in from the suction port by rotation of the air blower, to the heat exchange unit for heat exchange, and then guide the indoor air to the blow-out port;   a drain pan provided on a lower side of the heat exchange unit and defining part of an air passage communicating with the blow-out port; and   a projection projected upward from an upper portion of the drain pan and located in an upper region of end portions of the blow-out port.   
     
     
         5 . The ceiling-embedded air conditioner according to  claim 4 , wherein the louver comprises cut-out sections at longitudinal ends such that the cut-out sections are located upstream in the blowing direction.
