Rear grill assembly for box fan
Disclosed is a rear grill assembly for a box fan including a rear grill, an electric motor support positioned on the rear grill by a positioning structure, and a frame arranged on the periphery of the rear grill by a snap structure. The frame includes a bottom cover, a top cover, and two side boards connected between the bottom cover and the top cover. The electric motor support is positioned on the rear grill by the positioning structure so that the electric motor support can be mounted easily and firmly. Thus, shortening the time for mounting the motor support, and improving the efficiency for mounting the rear grill assembly. Moreover, since the bottom cover, the top cover and the two side boards are assembled to form a frame, each part can be produced separately, whereby the difficulty in producing the frame is decreased to a certain extent.
