Abstract:
A centrifugal air blower (100) and a fresh air device having the blower, wherein the
centrifugal air blower (100) comprises: a fan (10), an air flue (20) outside of
the fan, and a motor (30) for rotating the fan. The air flue (20) is a cavity formed between
two air flue plates (21,22), front plate (23), back plate (24) and the external
surface of the fan. Air outlets (25,26) are formed on the two ends of the air flue
respectively, thus two air flues (201,202) having two air outlets are formed.
When the fan rotates, it blows suction air in two directions simultaneously through
the two air flues and the two air outlets. The fresh air device comprises: a housing
(40), a centrifugal air blower group (200) assembled by the two centrifugal air
blowers, an air filter unit (50), and a front panel (60) used for controlling and
displaying. The present invention can improve the operating efficiency of the
fan, reduce volume, increase air delivery, and decrease noise and energy consumption.
