Contamination prevention technology of range hood and fan

摘要

[Challenge] To provide a technology that enables pollution prevention in a range hood or its fan that collects and discharges fumes generated in the kitchen. [Solution] All of the pressurized air of the fan (F) attached to the range hood is sent to the exhaust duct (D), and by the flow, softness and dirt generated in the kitchen are sucked from the gaps on the outer periphery of the range hood and the exhaust duct Due to the structure in which it is disposed of through the hood, the softness and dirt generated in the kitchen do not pass through the fan, and therefore, the fan attached to the range hood is not contaminated with the softness or dirt generated in the kitchen.
