Document Type and Number:
WIPO Patent Application WO/2019/163624
Kind Code:
A1
Abstract:
This blowing device has: a housing; a high-pressure air generation unit; a plurality of columnar bodies; and a control unit. The high-pressure air generation unit generates high-pressure air from air suctioned into a first space inside the housing, and sends the high-pressure air to a second space inside the housing. The plurality of columnar bodies are provided spaced apart from each other and extend radially from a side surface of the housing. Each of the plurality of columnar bodies has: a first air passage communicating with the second space in the housing; and a first blow-out port which is provided on the bottom part of the columnar body and communicates with the first air passage. The housing is provided with: a second air passage communicating with the second space; and a second blow-out port which is provided on the bottom part of the housing and communicates with the second air passage. The control unit selects one option among options including: a first mode in which an air amount ratio, which is the ratio between the amount of air blown from the first blow-out port and the amount of air blown from the second blow-out port, is a first value; and a second mode in which the air amount ratio is a second value smaller than the first value.
