Embodiment Construction

[0026] Below in conjunction with the accompanying drawings, the specific structure of the double-conical impeller for the range hood of the present invention will be described in detail:

[0027] see figure 1 As shown, the double-conical impeller for the range hood of the present invention is composed of the impeller front enclosure 1 , the impeller middle plate 2 , the impeller rear enclosure 3 , and the blades 4 .

[0028] The planes of the impeller front enclosure 1, the impeller middle disk 2, and the impeller rear enclosure 3 are arranged parallel to each other, and the blades 4 are installed between the impeller front enclosure 1 and the impeller middle disk 2 and the impeller middle disk 2 respectively. and between the impeller rear enclosure 3. The shaft sleeve 5 is fixed on the center of the disc 2 of the impeller through a rivet 6, so as to cooperate with the motor to drive the impeller to run.

[0029] Please combine figure 2 As shown, in order to ensure that th...

Abstract

The invention provides a biconical impeller for a range hood. The biconical impeller is composed of an impeller front enclosed ring, an impeller central disk, an impeller rear enclosed ring and blades, wherein, the blades are vertically arranged between the impeller front enclosed ring and the impeller central disk and between the impeller rear enclosed ring and the impeller central disk, and thediameter of the impeller front enclosed ring and diameter of the impeller rear enclosed ring are respectively greater than that of the impeller central disk. By utilizing the biconical impeller provided by the invention, the air quantity of a fan is increased and simultaneously noise is effectively reduced.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, in particular to a double-cone impeller for a range hood. Background technique [0002] At present, the range hood has become an indispensable kitchen appliance in the family, and it is mainly composed of a casing and an internal multi-blade centrifugal fan. The multi-blade centrifugal fan is the core component of the fan, consisting of an impeller and a volute. The impeller plays the role of energy conversion, and its performance directly affects the performance of the range hood. Most of the existing impellers are "squirrel cage" type, with a large number of blades, a single arc shape, a right angle at the bottom, and limited air volume and suction. [0003] Practice has found that when the airflow enters the interior of the multi-blade centrifugal fan impeller, a certain distance is required to achieve the conversion from axial to radial. From the front disk of the impeller to the mi...
