Abstract

The invention provides a centrifugal fan. The centrifugal fan includes: a casing, an air inlet is opened on the cover, and a plurality of air outlets are opened on the surrounding wall; a wind wheel assembly, which has a wind wheel motor and a plurality of fan blades; an air supply control device, which is rotatably arranged in the casing, and has one or more shielding parts; the adjusting motor is arranged on the radially outer side of the surrounding wall; Each shielding part is rotated to different rotation positions to completely cover, partially cover or fully expose each air outlet, thereby adjusting the respective air outlet areas of the multiple air outlets. The centrifugal fan can controllably shield multiple air outlets through the rotation of the air supply control device, so as to realize simultaneous air supply to multiple directions / multiple places, and can select the air outlet direction / air supply place and Adjust the air volume of each air outlet to achieve a reasonable air supply.

Description

technical field [0001] The invention relates to the technical field of fan air supply, in particular to a centrifugal fan. Background technique [0002] The existing centrifugal fan is only provided with one air outlet. When air needs to be supplied to two or more different directions or multiple positions, it is necessary to set up multiple fans or add external joints matched with the fans to meet the requirements of different directions or multiple positions. The need for air supply at multiple locations. This leads to an increase in cost, and in some special occasions, multiple fans cannot be installed due to space constraints, which will affect production or use. In addition, the installation of external joints not only increases the cost, but also greatly increases the air supply resistance and reduces the air volume. , the air supply efficiency is low. SUMMARY OF THE INVENTION [0003] One object of the present invention is to overcome at least one defect of the ex...
