Document Type and Number:
WIPO Patent Application WO/2020/071292
Kind Code:
A1
Abstract:
[Problem] To provide a technology that can prevent soiling of a range hood and a fan thereof for collecting and discharging oil smoke generated in kitchens. [Solution] Due to a structure in which all the compressed air of a fan F attached to the range hood is sent to an exhaust duct D, and by such a flow, the oil smoke and dirt generated in the kitchen are suctioned from the gap on the outer periphery of the range hood and discarded through the exhaust duct, no oil smoke or dirt generated in the kitchen will pass through the fan, and accordingly the fan attached to the range hood will not be soiled by oil smoke or dirt generated in the kitchen.
