Abstract
The present invention relates to the fume exhauster technology field, and especially relates to a cooking fume exhauster with a simple structure, high service efficiency and purification function. Compared with the prior art, the cooking fume exhauster is provided with two purification fans in a purification room. An air-out room is provided with an air-out fan. Water runs through long axes or hubs of the two purification fans to form a layer of water screen. The oil fume gas blew from an air-in room all passes through the purification fan with the water screen. The water screen on the purification fan purifies the solid granule of oil and fume in the oil fume gas to make the solid granule to be merged into the water thoroughly, so as to purify the gas. The air-out fan discharges the purified gas, thereby causing a great pressure in the air-in room. By means of the effective cooperation of three fans, the contaminative gas with oil fume is fast discharged and purified, and the cooking fume exhauster of the invention has well purification and exhaust effect.
