Referring to fig. 1 and 2, the above-described smoke collecting hood assembly 2 includes a smoke collecting hood 21 and a shutter 22, the smoke collecting hood 21 being installed below the wind box 12, and a smoke intake chamber being formed in the smoke collecting hood 21. For the top-suction type range hood, the bottom plate of the fume collecting hood 21 is provided with a fume inlet 210 communicated with the fume inlet cavity; for the side-draft range hood, the side surface of the fume collecting hood 21 is provided with a fume inlet 210 communicated with the fume inlet chamber. The shutter 22 is installed at the smoke inlet 210 to close the smoke inlet 210.

The electric control system is arranged above the air box 12 and positioned in the decorative plate 11, and the lighting system is arranged below the decorative plate 11; the control switch can be arranged on the fume collecting hood 21 and is electrically connected with the electric control system, the fan system and the lighting system.

When the range hood 100 receives the operation instruction, the power switch is turned on, the fan 6 is controlled to start (the lighting device can be turned on according to the needs of the user), the fan sucks the oil smoke generated by cooking into the smoke inlet cavity through the smoke inlet 210, and the oil smoke is discharged to the public flue or the outdoor through the air channel in the air box 12, so that the oil smoke suction function of the range hood 100 is realized.

For the top-suction range hood, the distance between the smoke inlet 210 of the range hood 100 and the pot on the cooking range is large, so that the problems that the oil smoke on one side cannot be discharged timely and the oil smoke escapes easily occur; and if adopt near-suction type range hood, though range hood 100's smoke inlet 210 is less with the interval of pan on the kitchen range, oil smoke exhaust efficiency improves, nevertheless to adopting highly great steamer to cook, when the fender cigarette board of range hood 100's smoke inlet 210 department installation was opened, kept off the cigarette board and touch the steamer easily for user experience is relatively poor.

Therefore, in order to solve the above problem, referring to fig. 3 and 4, in the range hood 100 of the embodiment of the present application, there are a plurality of smoke inlets 210, and the plurality of smoke inlets 210 are arranged at intervals along the length direction P of the smoke collecting cover 21; the number of the shielding pieces 22 is also multiple, and one or more shielding pieces 22 are arranged at each smoke inlet 210; the extractor hood 100 further comprises a driving device 3, wherein the driving device 3 can drive one or more shielding pieces 22 to close or rotate outwards to open. The longitudinal direction P of the smoke collecting hood 21 is parallel to the direction in which the burner of the gas range is arranged.
