Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
fig. 2 is a top view of an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1 and fig. 2, the range hood of the present embodiment includes a smoke collecting hood 1 and a fan housing 2 disposed above the smoke collecting hood, and a smoke exhaust channel 3 and an air outlet channel 4 separated from each other are disposed inside the fan housing 2. The direction indicated by arrow a in fig. 1 is taken as the right, and the smoke exhaust channel 3 is located at the left side of the air outlet channel 4.
A first fume suction fan 51 and a second fume suction fan 52 are installed in the fume exhaust channel 3, a first air supply fan 61 and a second air supply fan 62 are installed in the air outlet channel 4, and an air inlet 21 and an air outlet 22 communicated with the air outlet channel 4 are arranged on the fan outer cover 2. In this embodiment, the air inlet is disposed at the rear portion of the air outlet channel 4, the air inlet grille 8 is disposed at a position, close to the air inlet 21, at the rear portion of the air outlet channel 4, and the air outlet 22 is disposed at the middle portion of the front surface of the fan housing 2.
The first fume exhaust fan 51 and the second fume exhaust fan 52 of this embodiment are both centrifugal fans, the first fume exhaust fan 51 is adjacent to the left sidewall of the fume exhaust channel 3 and the air inlet is facing right, and the second fume exhaust fan 52 is adjacent to the top of the fume exhaust channel and the air inlet is facing downward. Thus, the air inlets of the first fume exhaust fan 51 and the second fume exhaust fan 52 are perpendicular to each other, so that a better air inlet effect can be obtained, and the fume exhaust effect can be improved. The smoke exhaust channel 3 may be provided with a smoke exhaust port shared by the first smoke exhaust fan 51 and the second smoke exhaust fan 52, or may be provided with two smoke exhaust ports, so that each smoke exhaust fan corresponds to an independent smoke exhaust port.
