Description

Air outlet cover and range hood provided with same

Technical Field

The utility model relates to a range hood especially relates to a go out fan housing and install range hood of this play fan housing.

Background

Chinese cooking can produce a large amount of oil smoke, and in order to keep the kitchen environment clean and the health of human body, the range hood has become one of the indispensable equipment in modern family kitchen. The range hood inhales gas at the air inlet of the range hood during operation, and the gas is discharged through the air outlet of the fan. The existing range hood is generally provided with an air outlet cover at an air outlet of a fan, and the air outlet cover has the functions of gathering air, guiding flow and connecting the range hood with an air outlet pipe. The air current that the fan produced all needs assemble in the air-out cover finally, and this air current that just makes in the air-out cover is too concentrated, and the internal air current motion of cover produces the torrent and sends the noise, and then influences people's culinary art and experience and healthy. Because the existing range hood only has one smoke outlet, the air outlet cover also correspondingly has only one outlet.
