Abstract

The invention discloses a range hood. The range hood comprises a fan frame used for arranging a fan system, the range hood further comprises a hollow lower box body, the lower box body is located below the fan frame and is in fluid communication with the fan frame, and a first air inlet and a second air inlet which are arranged in a left-right spaced mode are formed in the bottom of the lower box body; a first cavity and a second cavity which serve as air inlet cavities are formed in the lower box body, the first air inlet corresponds to the first cavity, and the second air inlet corresponds to the second cavity; and the range hood further comprises a filtering device, the filtering device is used for allowing oil fume airflow of the first cavity and the second cavity to pass through and can move left and right, and therefore the passing proportion of the oil fume airflow of the first cavity and the passing proportion of the oil fume airflow of the second cavity are changed. Compared with the prior art, the range hood has the advantages that the total air volume does not need to be increased, so that the cooking fume suction effect can be greatly improved on the same side of the corresponding range hood during single-side stir-frying cooking.

Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a range hood. Background technique [0002] Chinese cooking will produce a lot of oil fumes. In order to keep the kitchen environment clean and the human body healthy, range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top-suction and side-suction types, and top-suction range hoods are more and more widely used because of their neatness, lightness, small footprint, good matching with wall cabinets, and low noise. [0003] The top suction range hood usually includes a smoke collection hood and a fan frame located on the smoke collection hood. A volute, an impeller and a motor for driving the impeller are installed in the fan frame. The negative pressure area is directly connected, and this type of range hood is equipped with a filter at the air inlet. When the oil fume passes through the filter, it will be parti...
