Claims

[Scope of Claim for Utility Model Registration] (1) In a fan guard provided at the air outlet opposite to the propeller fan of an air conditioner, the fan guard is inclined so as to move away from the fan from the center to the outer periphery, and the center is recessed. A plurality of vertical ribs arranged radially, a plurality of horizontal ribs arranged concentrically to connect these vertical ribs in a circumferential manner and having a surface parallel to the wind blowing direction, and an outer peripheral end of the vertical ribs. A fan guard for an air conditioner, which is fixed to the fan and consists of the horizontal ribs surrounding the outer periphery of the fan and a concentric cylindrical bell mouth. (2) Utility model registration claim 1, in which the vertical rib is curved to form a convex portion in the wind blowing direction between the horizontal rib on the outermost periphery and the bell mouth.
Fan guard for air conditioners as described in section. (3) Between the horizontal ribs on the outermost periphery and the bell mouth, between the adjacent vertical ribs, another vertical rib curved in the same way as these vertical ribs is arranged radially. Fan guard for air conditioners as described in section.
