The invention relates to the field of cooking fume diversion, in particular to an impeller for a cooker hood and the cooker hood. The impeller for the cooker hood comprises a front plate, vanes and a rear plate, wherein the front plate and the rear plate are installed at two ends of the vanes. The impeller for the cooker hood is characterized by also comprising roll rim structures which comprise first roll rims arranged on the front plate, and / or second roll rims arranged on the rear plate; the first roll rims are arranged at the front surface of the front plate; the first roll rims and the front surface of the front plate form a sealed arc shape; the second roll rims are arranged at the rear surface of the rear plate; and the second roll rims and the rear surface of the rear plate form a sealed arc shape. According to the roll rim structures provided by the invention, the arc shape of a sealed arc-shaped mechanism of the first roll rims arranged on the front plate or the second roll rims arranged on the rear plate has a certain diversion function on the leaked air flow, and the collision of the leaked air flow passing through the roll rims and a separation vortex produced after passing through the roll rims are reduced, so that the aerodynamic noise is reduced.
Description
technical field [0001] The invention relates to the field of oil fume diversion, in particular to a conventional impeller and a range hood. Background technique [0002] With the improvement of people's health awareness, kitchen range hoods have gradually become an indispensable electrical appliance for every family. At present, the large air volume and suction power recognized by consumers has become the main selling point of the market, but the hood itself has the contradiction that the greater the air volume, the greater the noise. For example: figure 1 and 2 The figure shows the basic structure of the multi-blade centrifugal fan, which is the main component in the existing range hood, and is mainly composed of an air inlet ring 1, an impeller 2, a motor 3, a volute 4, and a lock nut 5. A certain gap 6 should be maintained between the impeller of the fan and the volute, the air inlet ring and the motor shaft to ensure the reliability of the fan rotation. However, thes...
