Abstract

The invention relates to an air conditioner draught fan box which comprises a frame and foaming panels. The frame comprises three-way pieces, frame strips, edge frame pressing plate strips and liner pressing plate strips. The corresponding frame strips are inserted in the three ways of each three-way piece respectively in a matched mode, the liner pressing plate strips are connected to the frame corners, facing the inner side of the box, of the frame strips in the length direction of the frame strips in a sliding mode, and the foaming panels are fixed and clamped by the liner pressing plate strips and the edge frame pressing plate strips. Protruding limiting ribs and protruding screw seats are arranged on the sides, used for clamping the foaming panels, of the edge frame pressing plate strips, limiting grooves matched with the protruding limiting ribs are formed in the outer side frame faces of the frame strips, the liner pressing plate strips and the protruding screw seats of the edge frame pressing plate strips are fixedly connected through self-drilling and self-tapping screws with pads in the direction towards the edge frame pressing plate strips from the liner pressing plate strips, and the self-drilling and self-tapping screws with the pads do not penetrate through the edge frame pressing plate strips after being fastened to the protruding screw seats. The air conditioner draught fan box is reliable in structural connection, the screw pieces are not exposed, integral attractiveness is achieved, the sealing performance and the cold-bridge prevention effect are good, and the air conditioner draught fan box is suitable for serving as boxes of various air conditioner draught fans.
