Document Type and Number:
WIPO Patent Application WO/2021/039754
Kind Code:
A1
Abstract:
According to the present invention, airflows in a suction side plate (32) direction and an opposing side plate (13) direction are divided into two on an outer peripheral side and an inner peripheral side by means of the shape of a scroll (33), thereby creating a uniform airflow that is wider the width of a blow-out opening (72). This makes it possible to provide an efficient blower in which, by causing a uniform airflow to pass through a ventilation opening, the pressure loss when louvers are installed is low, and to provide an air supply fan provided with said blower.
