Outdoor unit of air-conditioning apparatus

Abstract

[Object] To provide an air-conditioning-apparatus outdoor unit including a socket that can be used in cold climate areas. [Solution] An outdoor unit 100 includes a base plate 12 having a hole 13 and a socket 50 attached to the base plate 12 with a clearance 16 provided between the socket 50 and a lower surface of the base plate 12 , the socket 50 communicating with the hole 13 to provide a first drainage path. The clearance 16 functions as a second drainage path for allowing drain water from the hole 13 to be guided out of the outdoor unit 100 when the first drainage path is blocked.

1 . An outdoor unit of an air-conditioning apparatus, the outdoor unit comprising:
 a base plate having at least one hole; and   a socket attached to the base plate with a clearance provided between the socket and a lower surface of the base plate, the socket communicating with the hole to form a first drainage path,   wherein the clearance is provided so as to function as a second drainage path that allows drain water from the hole to be guided out of the outdoor unit when the first drainage path is blocked.   
     
     
         2 . The outdoor unit of the air-conditioning apparatus of  claim 1 ,
 wherein the socket includes a base plate connection portion attached to the base plate,   wherein the base plate connection portion includes
 an outer wall part that is hollow and serves as an outer wall of the base plate connection portion, the outer wall part being shaped so as to expand toward the base plate in side view, 
 a lug having a first end connected to an inner surface of the outer wall part and a second end projecting beyond a top end of the outer wall part, and 
 a catch having a first end connected to the inner surface of the outer wall part and a second end projecting beyond the second end of the lug, and 
   wherein the catch extends through the hole and the second end of the lug is in contact with the lower surface of the base plate such that the clearance is provided between the top end of the outer wall part and the lower surface of the base plate.   
     
     
         3 . The outdoor unit of the air-conditioning apparatus of  claim 1 , wherein the clearance is greater than or equal to 5 mm. 
     
     
         4 . The outdoor unit of the air-conditioning apparatus of  claim 2 , wherein the catch has a slit-shaped elongated hole. 
     
     
         5 . The outdoor unit of the air-conditioning apparatus of  claim 1 , further comprising:
 a rib disposed in the first drainage path so as to extend across a cross-section of the first drainage path.   
     
     
         6 . The outdoor unit of the air-conditioning apparatus of  claim 1 , wherein the socket includes a hose connection portion including a corrugated part and a cylindrical straight part connected in series. 
     
     
         7 . The outdoor unit of the air-conditioning apparatus of  claim 1 ,
 wherein the socket includes a hose connection portion including a plurality of cylindrical straight parts having different outside diameters connected in series, and   wherein a cylindrical straight part having a larger outside diameter is disposed closer to the base plate.   
     
     
         8 . The outdoor unit of the air-conditioning apparatus of  claim 1 ,
 wherein the socket includes a hose connection portion including a corrugated part and a plurality of cylindrical straight parts having different outside diameters connected in series, and   wherein the corrugated part, a cylindrical straight part having a larger outside diameter of the plurality of cylindrical straight parts, and a cylindrical straight part having a smaller outside diameter of the plurality of cylindrical straight parts are arranged in order from a side close to the base plate.   
     
     
         9 . The outdoor unit of the air-conditioning apparatus of  claim 1 , wherein the at least one hole of the base plate includes a plurality of holes. 
     
     
         10 . The outdoor unit of the air-conditioning apparatus of  claim 1 , further comprising a heater disposed on the base plate.
