This will increase the cost, and in some special occasions, due to space constraints, multiple fans cannot be installed, 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, reducing the air volume. , the air supply efficiency is low, and the air supply volume of each joint cannot be controlled

Abstract

A centrifugal fan, comprising: a housing (20) in which an air inlet space which is in communication with an air inlet, and a plurality of air discharging ducts which extend in a curved manner, are defined; a vane wheel (30), configured such that an air flow flows into the housing (20) from the air inlet and flows out from the housing (20) via one or more air outlets; a plurality of flaps (40) for adjusting air discharging areas of the plurality of air outlets or air discharging ducts, respectively; a rotary member (50); and a driving mechanism (60), configured to transfer the rotary motion of the rotary member (50) to the plurality of flaps (40), such that the plurality of flaps (40) move to their respective blocking positions. The centrifugal fan can, by means of the rotation of the rotary member (50), drive the flaps (40) to move to controllably block the plurality of air outlets, realizing simultaneous air blowing in multiple directions. Moreover, the centrifugal fan can choose a direction to discharge air and adjust the amount of air discharged by each air outlet, realizing appropriate air blowing.

Description

technical field [0001] The invention relates to the technical field of fan air supply, in particular to a centrifugal fan. Background technique [0002] Existing centrifugal fans are provided with only one air outlet. When it is necessary to supply air to two or more different directions or multiple positions, it is necessary to install multiple fans or add external joints matching the fans to meet the needs of different directions or locations. The demand for air supply in multiple locations. This will increase the cost, and in some special occasions, due to space constraints, multiple fans cannot be installed, 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, reducing the air volume. , the air supply efficiency is low, and the air supply volume of each joint cannot be controlled. Contents of the invention [0003] An object of the present invention is t...
