Description

Technical Field

[0001] The utility model relates to the technical field of firewood integrated stoves, in particular to a fan installation structure of a firewood integrated stove. Background Art

[0002] Firewood integrated stoves are generally equipped with a smoke exhaust device to exhaust the smoke generated in the furnace. The smoke exhaust device includes a fan, which is fixedly installed in the installation cavity of the integrated stove.

[0003] There are generally two existing ways to install fans. The first is to set screw holes on the front side wall or rear side wall of the fan, and screw them to the front cavity wall or rear cavity wall of the installation cavity through the screw holes; the second is to set an annular flange around the air outlet of the fan, set screw holes on the flange, and screw them to the left cavity wall or right cavity wall of the installation cavity through the screw holes.

[0004] Whether it is the first installation method or the second installation method, the fan needs to be pre-fixed in a preset installation position with tools or hands, and then screws are injected in the horizontal direction to fix the fan. The actual disassembly and assembly process is relatively inconvenient. Therefore, the fan installation structure has certain room for improvement. Utility Model Content

[0008] As a further improvement of the above technical solution, the step surface is arranged on the left and right sides of the installation cavity, and the lateral extension part is arranged on the left and right sides of the fan.

[0009] As a further improvement of the above technical solution, the upper end of the left side wall or the right side wall of the installation cavity is inclined outward.

[0010] As a further improvement of the above technical solution, a through hole is provided on the left side wall of the installation cavity, and the air outlet on the fan is located on the through hole; the through hole is located below the step surface, and the lateral extension portion is provided on the upper edge of the air outlet.
