Side air draft range hood is the side that the inlet scoop is arranged at kitchen range, and its typical case is represented as more advanced side draught wall built-up type range hood and vertical fume removing cabinet.The oil smoke of this side air draft range hood freely spreads height to be reduced compared with last air-exhaust type range hood greatly, so the oil suction effect is better.But blower fan is installed in the human body head place equally, and noise is very big.
The typical case of following air draft range hood is represented as down air draft range hood one kitchen range, and its classical architecture is directly on the sidewall above the kitchen range inlet scoop to be housed, and is aided with guide duct again, and is by blower fan that the oil smoke sucking-off is outdoor.The oil smoke of this time air draft range hood highly only freely spreads about 1cm, therefore can improve oil suction cigarette effect greatly, can accomplish basically that oil smoke does not also spread out just to be sucked away discharge.Yet the blower fan of this range hood is the below that is installed on kitchen range, though from far away than last air-exhaust type and side air-exhaust type of head part's distance, but bigger.And blower fan also occupied the space of kitchen range below, and structure is not compact.
In a word, existing range hood exists shortcomings such as noise is big, structure is not compact widely, haves much room for improvement in fact.
The utility model content
