Title:
VENTILATOR
Document Type and Number:
WIPO Patent Application WO/2022/009929
Kind Code:
A1
Abstract:
This ventilator (100) comprises an up-down louver (31), a plurality of left-right louvers (41) provided in a direction intersecting with the up-down louver (31) and disposed more on the upstream side in the air flow direction than the up-down louver (31), and a first tilted member (21) that is tilted such that the opening area of an opening part (110) widens from the upstream side to the downstream side in the air flow direction. In a maximum-angle state in which the up-down louver (31) has been rotated so that an upstream end part (31c) of the up-down louver (31) is closest to the first tilted member (21), the upstream end part (31c) is positioned more on the downstream side in the air flow direction than an apex (21a). A protruding part (6a) that is disposed adjacent to the apex (21a) of the first tilted member (21) on the upstream side in the air flow direction projects more inside of a flow path (11) than the apex (21a) does in a direction that is orthogonal to both the rotation axis of the up-down louver (31) and the air flow direction, and viewed from the air flow direction, is provided extending so as to cross the plurality of left-right louvers (41).
