Enveloping type wind wheel air duct structure

Abstract

The invention discloses an enveloping type wind wheel air duct structure which comprises a motor bracket and a wind wheel; the motor bracket comprises an annular bracket main body and a plurality of guide vanes, and the guide vanes are arranged on the annular inner side of the bracket main body at equal intervals around the center of the bracket main body; and the tail edges of fan blades of the wind wheel are embedded among the guide vanes. The tail edges of the fan blades of the wind wheel are embedded among the guide vanes on the motor bracket, air flow is focused to the air outlet through the flow guide effect of the guide vanes, therefore, streaming loss is reduced, and the structure is applied to an air purifier, so that the aerodynamic performance and the air volume of the air purifier can be further improved.

Description

technical field [0001] The invention relates to the technical field of air purifiers, in particular to an enveloping wind wheel air channel structure. Background technique [0002] Air purifiers refer to products that can absorb, decompose or transform various air pollutants (such as PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), and effectively improve air cleanliness , Mainly divided into household, commercial, industrial, building and so on. The working principle of the air purifier is to generate a negative pressure area through the rotation of the centrifugal wind wheel, so that the air enters the interior of the air purifier, and various pollutants in the air are filtered by the internal filter element, and then the clean air is released. [0003] refer to figure 1 As shown, when the backward centrifugal wind wheel 2' is in operation, the airflow will enter from the negative pressure port of the wind wheel, and the h...

AI Technical Summary

Problems solved by technology

[0003] refer to figure 1 As shown, when the backward centrifugal wind wheel 2' is in operation, the airflow will enter from the negative pressure port of the wind wheel, and the high-speed rotation of the wind wheel blades 21' will generate centrifugal force. Under the action of centrifugal inertia and air duct, the airflow will Throw it out from the trailing edge of the blade 21' (the trailing edge is defined as the tail of the blade 21' away from the negative pressure port of the wind rotor, occupying about 1 / 3 of the total height of the rotor 2'), and in the rotation Driven by the fan blade 21', a high-speed rotating flow will be formed at the trailing edge of the fan blade 21', resulting in a strong flow loss, which ultimately affects the aerodynamic performance and air volume of the air purifier
