The invention relates to the technical field of kitchen appliances, and particularly discloses a range hood with a layered oil fume discharge backflow-preventing treatment device. The range hood with the layered oil fume discharge backflow-preventing treatment device comprises an upper-layer air cabinet and a lower-layer air cabinet, wherein the upper-layer air cabinet and the lower-layer air cabinet are both internally provided with wind wheels, rotating shafts of the wind wheels are connected with the output ends of motors and are driven by the motors; the upper-layer air cabinet and the lower-layer air cabinet are sleeved with a machine body shell, an air outlet is formed in the top end of the machine body shell, a fume guide plate is installed at the bottom of the machine body shell, a fume guide opening is formed in the fume guide plate, and an oil collecting cup is installed at the bottom end of the fume guide plate. According to the range hood, the double motors, the double wind wheels and double volute shells are mounted in an vertically layered arrangement and mounting manner, so that the problem that oil fume cannot be completely discharged is solved, the conditions of backward flowing of the oil fume and the like are completely eradicated, and the fume discharging effect of the range hood is greatly improved.
Description
technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a range hood with a layered oil fume discharge anti-backflow processing device. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top-suction and side-suction types. Top-suction range hoods are neat, light, and take up less space. It has more and more widespread applications. [0003] The range hood has a fume pipe, which is connected with a fan, and the fume pipe is connected indoors and outdoors. An air inlet is provided on the fume collecting hood of the range hood, and the operation of the fan generates negative pressure to extract the fume generated during cooking. However, when the existing range hood is actually used, due to its weak suction, it is easy to cause the oil fume to flow backward, thereby affecting the consumer's experience of using the range hood; Th...
