The invention relates to an oil fume purification device, in particular to a range hood and a control method of the range hood.
Background
The range hood has become one of the indispensable kitchen household electrical appliances in modern families. The range hood works by utilizing the fluid dynamics principle, sucks and exhausts oil smoke through a centrifugal fan arranged in the range hood, and filters partial grease particles by using a filter screen. The centrifugal fan comprises a volute, an impeller arranged in the volute and a motor driving the impeller to rotate. When the impeller rotates, negative pressure suction is generated in the center of the fan, oil smoke below the range hood is sucked into the fan, accelerated by the fan and then collected and guided by the volute to be discharged out of a room.
The side-draft range hood absorbs most of oil smoke close to a cooking bench in an arc form by using a vortex air pressure principle, so that adverse effects on human health can be reduced, and the suction effect of a power source is basically not reduced because the power source is close to the cooking bench.
