Description

Fan mechanism for range hood and range hood

Technical Field

The invention relates to the technical field of intelligent household appliances, in particular to a fan mechanism for a range hood and a range hood comprising the fan mechanism for the range hood.

Background

At present, the double-cavity smoke machine enters air through a left smoke inlet and a right smoke inlet.

In order to improve the exhaust efficiency, some double-cavity smoke machines adopt fans with double-side air intake. The fan adopts a centrifugal fan and is longitudinally arranged, namely the axial direction of the centrifugal fan is horizontal and extends along the left and right directions of the double-cavity range hood. Through the fan capable of realizing bilateral air intake, the air intake and exhaust efficiency of two air inlets of the double-cavity range hood can be improved.

The fan with air inlet at two sides is provided with the center plate, so that the left side and the right side of the fan are isolated, the air inlet opposite turbulence at the left side and the right side is avoided, and the smooth smoke discharge is ensured.

However, the cavity for installing the fan in the double-cavity range hood still has a certain space after the fan is installed, a certain distance is reserved between the fan and the air inlet, and when the fan is opened to work, a certain distance is reserved between the air inlet on the smoke collection hood of the range hood and the air inlets on two sides of the fan, so that oil smoke cannot be smoothly sucked and removed by the fan at the first time, oil smoke dissipation is caused, the use environment of the range hood is not clean enough and environment-friendly, and the efficiency of removing the oil smoke under the condition of high energy consumption of the fan is low.

And the prior art also relates to two fans which are arranged side by side, and although the two fans can be operated independently, the total energy consumption is high when the two fans are started during double-side air inlet. If the energy consumption of a single fan is reduced, the air suction capability is deteriorated when the single fan is operated.
