BLOWER
Document Type and Number:
WIPO Patent Application WO/2021/085086
Kind Code:
A1
Abstract:
A fan (30) of a blower (1) comprises a dividing plate (34) for suppressing mixing of cabin-outside air flowing in a first vane passageway (310) and cabin-inside air flowing in a second vane passageway (320). A partition plate (57) is provided inside a casing to partition a ventilating path (53) for the air blown out from the fan into a first ventilating path (531) into which the cabin-outside air flows and a second ventilating path (532) into which the cabin-inside air flows. The dividing plate includes a rear-edge plate portion (342) positioned radially outside with respect to a first blade. The rear-edge plate portion has an end portion radially outside the rear-edge plate portion which is located radially outside of an upstream edge portion (571) of the partition plate opposite the fan and on the other side axially with respect to the upstream edge portion. The partition plate has an airflow turnaround portion (80) radially outside the rear-edge plate portion for causing the direction of the cabin-inside air moving toward a gap between the rear-edge plate portion and the partition plate to be turned around in a direction away from the partition plate.
