Abstract

The invention discloses a wind wheel (with a filter screen) for range hoods, which comprises a first support ring and a second support ring, wherein the first support ring and the second support ring are connected by blades arranged at a certain interval along the circumferential direction, the second support ring is connected with a filter screen, and the filter screen covers a ring hole of the second support ring. According to the invention, as the wind wheel is provided with the filter screen, when the wind wheel rotates, grids of the filter screen rotate and impact the lampblack, and then the lampblack is centrifugally separated, so that an effect of lampblack separation can be achieved before the lampblack reaches the blades of the wind wheel for range hoods, thereby avoiding the adherence of oil stains on a motor and the blades, reducing the cleaning of the motor and the blades of the wind wheel, and ensuring the lampblack extracting, discharging and separation effects of range hoods after being used for a long time.

Description

technical field

[0001] The invention belongs to the technology of kitchen range hoods, and in particular relates to a wind wheel structure of kitchen range hoods. Background technique

[0002] The currently widely used range hood wind wheel includes a first support ring and a second support ring, the first support ring is provided with a bracket for the driving device, and the first support ring and the second support ring are arranged at intervals along the circumference blade connection. The range hood with the wind wheel of this structure adopts a fixed filter screen arranged at the smoking port on the range hood housing. When the range hood is working, the wind wheel rotates under the drive of the motor, and the oil fume passes through the static filter screen on the smoking port, enters the ring hole of the second support ring, and is discharged through the gap between the axial blades. When the oil fume passes through the static filter, there is no centrifugal telemo...
