Air conditioner

Abstract

Air conditioner includes: a housing including an inlet, an outlet, and a discharge port, a blower configured to circulate air into or out of the housing, and a discharge device configured to guide a portion of the air blown toward the outlet by the blower to the discharge port. The discharge device includes a base fixed to the housing and configured to mount a movable drive source and a rotary drive source thereon, a discharge cover configured to open or close the discharge port, the discharge port being movable and rotatable with respect to the base, a movable transmission configured to receive power from the movable drive source to move the discharge cover, and a rotary transmission configured to receive power from the rotary drive source to rotate the discharge cover.

What is claimed is: 
     
         1 . An air conditioner comprising:
 a housing including an inlet, an outlet, and a discharge port;   a blower configured to circulate air into or out of the housing; and   a discharge device configured to guide a portion of the air blown toward the outlet by the blower to the discharge port;   wherein the discharge device comprises:
 a base fixed to the housing and configured to mount a movable drive source and a rotary drive source thereon, 
 a discharge cover configured to open or close the discharge port, the discharge cover being movable and rotatable with respective to the base, 
 a movable transmission configured to receive power from the movable drive source to move the discharge cover, and 
 a rotary transmission configured to receive power from the rotary drive source to rotate the discharge cover. 
   
     
     
         2 . The air conditioner of  claim 1 , wherein the movable transmission part comprises:
 a rotating member comprising a gear connected to the movable drive source and rotatable with respect to the base,   a transition member comprising a ring coupled to the rotating member so as to be rotatable together with the rotating member and movable with respect to the rotating member; and   a moving support configured to guide movement of the transition member while the rotating member rotates.   
     
     
         3 . The air conditioner of  claim 2 , wherein the transition member is coupled to the discharge cover to be movable together with the discharge cover and rotatable with respect to the discharge cover. 
     
     
         4 . The air conditioner of  claim 3 , wherein
 the discharge cover comprises a rotation support provided along the circumference of the discharge cover,   the transition member comprises a rotation coupler rotatably coupled to the rotation support, and   the transition member is configured to restrict movement with respect to the discharge cover as the rotation support and the rotation coupler are coupled.   
     
     
         5 . The air conditioner of  claim 4 , wherein the discharge device is configured such that:
 in response to operation of the movable drive source, the rotating member rotates,   in response to the rotation of the rotating member, the transition member moves with rotation, and   in response to the transition member moving with rotation, the discharge cover moves without rotation to open or close the discharge port.   
     
     
         6 . The air conditioner of  claim 2 , wherein
 the rotating member comprises a moving guide configured to guide the movement of the transition member, and   the transition member comprises a moving coupler movably coupled to the moving guide.   
     
     
         7 . The air conditioner of  claim 6 , wherein the discharge device comprises a moving cover including a moving rail configured to move the moving coupler together with the moving support member. 
     
     
         8 . The air conditioner of  claim 2 , wherein the moving support is formed integrally with the base. 
     
     
         9 . The air conditioner of  claim 1 , wherein the discharge cover is coupled to the rotary transmission to be rotatable together with the rotary transmission and movable with respect to the rotary transmission. 
     
     
         10 . The air conditioner of  claim 9 , wherein
 the rotary transmission comprises a part coupler extending along a direction of movement of the discharge cover,   the discharge cover comprises a cover coupler movably coupled to the part coupler, and   the discharge cover is configured to restrict rotation with respect to the rotary transmission as the part coupler and the cover coupler are coupled.   
     
     
         11 . The air conditioner of  claim 10 , wherein the discharge device is configured such that:
 in response to operation of the rotary drive source, the rotary transmission rotates, and   in response to the rotation of the rotary transmission, the discharge cover rotates without linear movement.   
     
     
         12 . The air conditioner of  claim 1 , wherein
 the discharge cover comprises a cover opening formed on a portion of an outer circumferential surface of the discharge cover, and   the cover opening is located inside the housing based on the discharge cover closing the discharge port, and   at least a portion of the cover opening is located outside the housing based on the discharge cover opening the discharge port.   
     
     
         13 . The air conditioner of  claim 1 , wherein based on the discharge cover opening the discharge port, a portion of the air blown by the blower is configured to be discharged through the outlet, and another portion of the air blown by the blower is configured to be discharged through the discharge port. 
     
     
         14 . The air conditioner of  claim 13 , wherein the discharge device comprises a discharge fan operable to discharge another portion of the air blown by the blower through the discharge port while the discharge cover opens the discharge port. 
     
     
         15 . The air conditioner of  claim 1 , wherein the discharge device is configured such that:
 based on the discharge cover moving, the rotary drive source is fixed to the base, and   based on the discharge cover rotating, the movable drive source is fixed to the base.
