Problems solved by technology
However, the oil fume passage from the air inlet of the cabinet to the inlet of the fan is still very complicated, and the influence of the space and gap between the casing of the fan system and the inner cavity of the cabinet on the airflow has not been completely resolved, and the flow loss is still very serious

The invention relates to a bellows of a range hood, which comprises a box body cover plate, a box body flange, a box body baffle and a box body top plate which are connected to form a semi-closed box body inner cavity, wherein a box body air inlet is arranged at the lower part of the box body flange, and a box body air outlet is arranged on the box body top plate; a fan outlet of a fan system of the range hood is arranged in a position opposite to the box body air outlet, and is positioned inside a box body, and a fan inlet is arranged on the fan system; an air inlet chamber is arranged at the fan inlet and is fixed on the fan inlet, and the air inlet chamber comprises an air inlet chamber baffle and an air inlet chamber bottom plate; and an oil fume channel from the box body air inlet tothe fan inlet is formed among the air inlet chamber baffle, the air inlet chamber bottom plate and the box body cover plate, and the distance between the air inlet chamber bottom plate and the box body cover plate gradually decreases in the direction from the box air inlet to the fan inlet. The bellows of the range hood has simple channel, low noise, large air quantity, low flow loss, skillful design and convenience and practicality.
Description
technical field [0001] The invention relates to a bellows of a range hood, which belongs to the modification technology of the bellows used in the range hood. Background technique [0002] European-style range hoods and near-suction range hoods occupy more than half of the current range hood market. The performance of European-style range hoods and near-suction range hoods directly affects consumers' mood and desire to buy. At present, the bellows systems of European-style range hoods and near-suction range hoods on the market are in a single form. There is a certain angle between the inlet and the air inlet of the box (mostly 90 degrees), and there are more spaces and gaps between the fan system shell and the box inner cavity (especially there are large spaces on both sides of the volute exit section), The oil fume passage from the air inlet of the box to the inlet of the fan is tortuous and complicated. When the flue gas flows from the air inlet of the box to the inlet of...
