[0002] Integrated stove is a kitchen appliance that integrates multiple functions such as range hood, gas stove, disinfection cabinet, storage cabinet, etc. It has the advantages of saving space, good fume extraction effect, energy saving, low consumption and environmental protection.

[0003] For example, a Chinese patent with authorization announcement CN219735417U and authorization announcement date September 22, 2023 discloses "An air collecting box structure for an integrated stove". The sealing plate of the volute of the fan close to the rear side plate of the bellows is removed and directly installed on the rear side plate of the bellows, and the rear side plate of the bellows is inclined. The surface where the air inlet of the fan is located is inclined, thereby improving the smoothness of the air flow from the air inlet of the bellows to the air inlet of the fan, thereby reducing wind resistance and increasing the air intake of the fan.

[0004] However, in the above-mentioned comparative patent, the sealing plate of the volute of the fan close to the rear side plate of the bellows is removed and directly installed on the rear side plate of the bellows, which causes the air outlet direction of the volute of the fan to be unable to be turned left and right, resulting in shortcomings during use.

The rotation axis of the impeller of the fan is parallel to the plane where the upper surface of the connecting plate is located; when the volute of the fan is rotated 180 degrees and installed front and back, the two connecting brackets can be placed on the upper surfaces of the two connecting plates, and the air outlet of the volute of the fan is connected to the corresponding square and round connecting pipes; the two sides of the cover plate are placed on the two connecting brackets, and the two sides of the cover plate, the connecting brackets and the connecting plates are connected by fixings.

[0007] The utility model is further configured as follows: the fixing member comprises a plurality of fixing screws which pass through the cover plate, are connected to the bracket and are threadedly connected to the connecting piece.

[0008] The utility model is further configured as follows: the cross section of the connecting piece is in an inverted "L" shape, and the connecting piece is fixed to the bellows by a plurality of connecting screws.

[0009] In summary, the beneficial effects of the utility model are:

[0010] 1. Connecting plates with upper surfaces extending downwardly and tilted away from the air inlet are symmetrically arranged on both sides of the installation opening of the bellows for installing the fan, so that when the two connecting brackets connected to the volute of the fan are placed on the two connecting plates, the rotation axis of the impeller of the fan is parallel to the plane where the upper surface of the connecting plate is located.
