Problems solved by technology

Regardless of whether the air curtain blows from top to bottom or from bottom to top, when the wind force of the air curtain is small, the oil fume is difficult to be confined in the area of ​​the air curtain. Certain interference, and the oil fume working condition is difficult to determine, a certain degree of air curtain has great limitations on the accumulation of oil fume

Abstract

The invention discloses a range hood. The range hood comprises an exhaust fume collecting hood and an exhaust fume gathering component, wherein a main air inlet is formed in the exhaust fume collecting hood; and an exhaust fume collecting cavity is formed inside the exhaust fume collecting hood. The range hood is characterized in that the exhaust fume gathering component comprises a first exhaustfume gathering plate and a second exhaust fume gathering plate; the first exhaust fume gathering plate is arranged at the left side of the exhaust fume collecting hood; the second exhaust fume gathering plate is arranged at the right side of the exhaust fume collecting hood; a first auxiliary air inlet is formed in the bottom of the first exhaust fume gathering plate; a second auxiliary air inletis formed in the bottom of the second exhaust fume gathering plate; the first auxiliary air inlet and the second auxiliary air inlet are in communication with the exhaust fume collecting cavity; and the first exhaust fume gathering plate and the second exhaust fume gathering plate can be in a closed state in which the corresponding auxiliary air inlets are located inside the exhaust fume collecting hood, and in the expanded state in which the corresponding auxiliary air inlets are at least partially located outside the exhaust fume collecting hood.

Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a 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] In order to better collect smoke, at present, the size of both ends of the smoke collecting hood is lengthened, such as adding smoke collecting panels on the left and...
