Document Type and Number:
WIPO Patent Application WO/2018/043793
Kind Code:
A1
Abstract:
The present invention relates to an intake device for a local exhaust ventilation device and, more particularly, to an intake device for a local exhaust ventilation device, comprising: a connection opening; a hood formed to connect an intake opening larger than the connection opening; an intake duct coupled to the hood so as to communicate with the connection opening; and an intake fan installed in the peripheral area of the intake opening to be able to generate an intake air stream directed from the intake opening toward the connection opening, wherein a plurality of intake fans are installed along the peripheral direction of the intake opening to be able to generate an intake air stream directed from the intake opening toward the connection opening; a mixed flow preventer is formed to protrude from the intake opening to the intake duct along the inside of a corner of the hood in a barrier type; multiple grating exhaust guide channels are arranged on straight lines, respectively, and formed to be isolated from each other; and an air stream alignment grating is installed in the inner space of the intake duct such that the grating exhaust guide channels are arranged along the longitudinal direction of the intake duct. Accordingly, it is possible to improve the air flow velocity inside the intake duct and the entire exhaust efficiency of the local exhaust ventilation device.
