Abstract

The invention discloses a range hood, comprising a fan frame for setting a fan system, the range hood further comprising a hollow lower box body, the lower box body is located under the fan frame and is in fluid communication, the The bottom of the lower box is provided with a first air inlet and a second air inlet arranged at intervals on the left and right, and a first chamber and a second chamber as air inlet chambers are formed inside the lower box. The air outlet corresponds to the first chamber, and the second air inlet corresponds to the second chamber; the range hood further includes a filter device, and the filter device allows the oil fume of the first chamber and the second chamber to pass through, And the filter device can move left and right, so as to change the ratio of the oil fume flow in the first chamber and the second chamber. Compared with the prior art, the present invention has the advantage that the total air volume does not need to be increased, so as to solve the problem that the same side of the corresponding range hood can greatly improve the effect of absorbing range hood when one side is stir-frying and cooking.

Description

technical field [0001] The invention relates to a lampblack purification device, in particular to a lampblack machine. Background technique [0002] Chinese cooking will produce a lot of oil fumes. In order to keep the kitchen environment clean and human health, range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top suction and side suction, and top suction range hoods are more and more widely used due to their neatness and lightness, small footprint, good match with hanging cabinets, and low noise. [0003] The top suction range hood usually includes a fume collecting hood and a fan frame located on the fume collecting hood. A volute, an impeller and a motor that drives the impeller are installed in the fan frame. The center of the fume collecting hood is provided with an air inlet and a height where the fan is located. The negative pressure area is directly connected, and this type of range hood is equipp...
