Abstract

The invention discloses a range hood. The range hood comprises a shell and a smoke barrier assembly, wherein an opening is formed in the front side of the shell, the smoke barrier assembly comprises asmoke barrier arranged at the opening so as to open or close the opening, the range hood is characterized in that the smoke barrier can be in a state of closing the opening or a state that the lowerend of the smoke barrier is upwards turned into the shell to open the opening, and the smoke barrier assembly further comprises an air inlet assembly which is arranged on the smoke barrier and can enable oil fume airflow to pass through and enter the shell. A control method of the range hood is further disclosed. Compared with the prior art, the range hood and the control method have the advantages that 1) the smoke barrier and the air inlet assembly are manufactured into a whole, parts are simplified, the smoke barrier is turned inwards, the risk of hitting a pot is avoided when the smoke barrier is opened, sight is not blocked when the smoke barrier is opened, visual oppression is reduced, and user experience is improved; and 2) an air inlet is internally formed, the smoke barrier and aleft and right side plates of the shell form a smoke collecting cavity, and the smoke collecting performance is improved.

Description

technical field [0001] The invention relates to a cooking fume purification device, in particular to a range hood and a control method for the range hood. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. The range hood uses the principle of fluid dynamics to work, sucks and exhausts the range hood through a centrifugal fan installed inside the range hood, and uses a filter to filter some grease particles. The centrifugal fan includes a volute, an impeller installed in the volute and a motor that drives the impeller to rotate. When the impeller rotates, a negative pressure suction is generated in the center of the fan, and the oil fume under the range hood is sucked into the fan, and after being accelerated by the fan, it is collected by the volute and guided out of the room. [0003] Generally, range hoods include top suction type and side suction type. The side suction type range hood uses the principle ...
