<p>A range hood ventilation module and assembly method thereof, the module comprising a primary tube (1), and an auxiliary tube (2) both made of integrally spun tubes; the auxiliary tube (2) is provided with an oil screen (22) in the front, and a connecting tube (21) in the back mated with the inner diameter of the primary tube (1); after an axial fan is installed in the primary tube (1), the primary tube is abutted with the auxiliary tube (2) to form the ventilation module. The assembly method of the ventilation module comprises: after installing a fixing bracket on the range hood ventilation module, the ventilation module is disposed in a smoke collection box (6) at the top of the range hood (5), and is connected to the smoke collection box (6) via the fixing bracket. The primary tube (1) and the auxiliary tube (2), being made by spinning a tube to form a cylinder, therefore have no seams or welded spots on the outer side. By installing an axial fan in the cylindrical range hood, oil smoke is directly discharged after passing through the fan. With an unobstructed ducts, the present invention improves fan efficiency, and reduces working noise and energy consumption.</p> |
