AIR-BLOWING UNIT
Document Type and Number:
WIPO Patent Application WO/2020/230562
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to provide an air-blowing unit capable of extending the reach of the air stream blown toward an object to be blown upon with minimal increase in body size. An air-blowing unit (50, 60, 70, 80) is equipped with a duct (51, 61, 71, 81) that forms a blowout flow path (510, 610, 710, 123B) through which the air blown toward the object to be blown upon passes. The air-blowing unit is equipped with a hole formation member (52, 62, 63, 72, 73, 82) that forms a blowout hole (520, 620, 630, 720, 730, 820) in the shape of a flattened hole, through which air is blown toward the object to be blown upon, in the duct at the downstream side of the air flow. The hole periphery part (521, 621, 631, 721, 731, 821) of the hole formation member which surrounds the blowout hole is provided with a diffusion suppression unit (53, 66, 67, 76, 77, 83) at one of a pair of long edges and a pair of short edges, the diffusion suppression unit (53, 66, 67, 76, 77, 83) suppressing the diffusion of the air stream blown from the blowout hole toward the object to be blown upon.
