Outdoor unit for refrigeration cycle apparatus

Abstract

An outdoor unit for a refrigeration cycle apparatus includes: a heat exchanger having an outer surface inclined downward; a drain pan on which the heat exchanger is set; a top frame on which a fan is set, the top frame being disposed at a top of the heat exchanger; and a support attached to the drain pan and the top frame, the support extending between the drain pan and the top frame.

1 . An outdoor unit for a refrigeration cycle apparatus, the outdoor unit comprising:
 a heat exchanger having an outer surface inclined downward;   a drain pan on which the heat exchanger is set;   a top frame on which a fan is set, the top frame being disposed at a top of the heat exchanger; and   a support attached to the drain pan and the top frame, the support extending, along the outer surface of the heat exchanger, between the drain pan and the top frame.   
     
     
         2 . The outdoor unit for a refrigeration cycle apparatus of  claim 1 , the outdoor unit further comprising a plurality of supports. 
     
     
         3 . The outdoor unit for a refrigeration cycle apparatus of  claim 1 , wherein the support has an L shape. 
     
     
         4 . The outdoor unit for a refrigeration cycle apparatus of  claim 1 , wherein the support is detachably attached to the drain pan and the top frame. 
     
     
         5 . The outdoor unit for a refrigeration cycle apparatus of  claim 4 , wherein when a dimension of a long side of the support is a length L, a dimension of a short side of the support is a length d, an inclination of the long side of the support relative to a vertical direction is an angle θ, and an inclination of the short side of the support relative to a horizontal direction is an angle α, the drain pan is formed such that a depth hd of the drain pan satisfies an expression of hd>L×(1−cos θ)+d×sin α. 
     
     
         6 . The outdoor unit for a refrigeration cycle apparatus of  claim 1 , wherein the heat exchanger has a flat shape, an L shape, or a U shape. 
     
     
         7 . The outdoor unit for a refrigeration cycle apparatus of  claim 1 , the outdoor unit further comprising a design panel attached between the drain pan and the top frame. 
     
     
         8 . The outdoor unit for a refrigeration cycle apparatus of  claim 7 , wherein the design panel is formed of a combination of a plurality of panels. 
     
     
         9 . The outdoor unit for a refrigeration cycle apparatus of  claim 8 , wherein
 one of the plurality of panels is a drain pan maintenance panel, and   the drain pan maintenance panel is provided with a guide component configured to guide, to the drain pan, water droplets adhered to an inner surface of the drain pan maintenance panel.
