Outdoor unit for air-conditioning apparatus

Abstract

In an outdoor unit for an air-conditioning apparatus, an upper end of an upper anchoring portion of a fan guard is bent toward a casing and then formed upward, a lower end of a lower anchoring portion is bent toward the casing, a lower anchoring distal end portion that is a distal end-side portion of the lower anchoring portion is bent such that a distal end is oriented downward, a front panel includes an upper temporary fixing groove in which the upper anchoring portion is inserted and that restricts movement of the upper anchoring portion in a right and left direction and a lower temporary fixing hole in which the lower anchoring portion is inserted and that restricts movement of the lower anchoring portion in a forward direction and in a downward direction, and the upper temporary fixing groove and the upper anchoring portion are covered with a top panel.

1 . An outdoor unit for an air-conditioning apparatus, the outdoor unit comprising:
 a casing including a front panel and a top panel, the front panel having an opening; and   a fan guard made up of a combination of a plurality of vertical bars and a plurality of horizontal bars, the fan guard covering the opening, wherein   the fan guard includes
 an upper anchoring portion formed at an upper end of one of the vertical bars, located at a center in a right and left direction of the casing, or each of upper ends of at least two of the vertical bars, located apart from each other in a right and left direction of the casing, and 
 a lower anchoring portion formed at a lower end of a plurality of the vertical bars, located apart from each other in the right and left direction of the casing, 
   the upper anchoring portion is formed such that the upper end is bent toward the casing and further bent upward,   the lower anchoring portion is formed such that the lower end is bent toward the casing,   a distal end of a lower anchoring distal end portion that is a distal end-side portion of the lower anchoring portion is bent so as to be oriented downward,   the front panel includes
 an upper temporary fixing groove in which the upper anchoring portion is inserted and that restricts movement of the upper anchoring portion in the right and left direction, and 
 a lower temporary fixing hole in which the lower anchoring portion is inserted and that restricts movement of the lower anchoring portion in a forward direction and in a downward direction, and 
   the upper temporary fixing groove and the upper anchoring portion are covered with the top panel.   
     
     
         2 . The outdoor unit for an air-conditioning apparatus of  claim 1 , wherein
 the upper temporary fixing groove opens on the front of the casing.   
     
     
         3 . The outdoor unit for an air-conditioning apparatus of  claim 1 , wherein
 the upper temporary fixing groove has a curved surface recessed in a cylindrical shape.   
     
     
         4 . The outdoor unit for an air-conditioning apparatus of  claim 1 , wherein
 a width of the upper temporary fixing groove is equal to or less than a width of the upper anchoring portion.   
     
     
         5 . The outdoor unit for an air-conditioning apparatus of  claim 1 , wherein
 the upper temporary fixing groove has a protrusion at a front of the upper temporary fixing groove.   
     
     
         6 . The outdoor unit for an air-conditioning apparatus of  claim 1 , wherein
 the lower temporary fixing hole opens upward.   
     
     
         7 . The outdoor unit for an air-conditioning apparatus of  claim 1 , wherein
 the lower temporary fixing hole is defined by a lower edge located at a lower side of the front panel and an upper edge located at an upper side of the front panel, and   the lower edge is located at a further front side of the casing than the upper edge.   
     
     
         8 . The outdoor unit for an air-conditioning apparatus of  claim 1 , further comprising:
 a contact portion provided at the lower end of the vertical bar in which the lower anchoring portion is not formed, the contact portion contacting with a surface of the front panel, wherein   a force that acts on the fan guard by contact between the contact portion and the surface of the front panel is opposite to a force that acts on the fan guard by contact between the lower anchoring distal end portion and a portion of the casing forward of the lower temporary fixing hole.
