As another embodiment of the present application, as shown in fig. 1 and fig. 2, the present embodiment provides a range hood, which includes a body 10, a fan assembly 20, and an air intake assembly 30 as any one of the above, where the body 10 has a main air inlet 11 and an air outlet, the fan assembly 20 is disposed in the body 10, the fan assembly 20 may be located at a center of the body 10 in a transverse direction (horizontal direction) of the body 10, a center line 317 of the air intake plate 31 corresponds to the position of the fan assembly 20, for example, the center line of the fan assembly 20 may intersect with the center line 317 of the air intake plate 31, and the air intake assembly 30 is disposed at the body 10 and located at the main air inlet 11.

When the fan assembly 20 starts to work, the first air inlet portion 311 and the second air inlet portion 312 simultaneously supply air, which is equivalent to simultaneously supply air at two sides of the fan assembly 20, so that the air flows at two sides of the fan assembly 20 can be balanced, and the generation of noise due to the disorder of the air flow in the machine body 10 can be avoided.

According to the air intake assembly 30 provided by the application, a gap for air circulation is formed between the second panel 33 and the air intake plate body 31, and the second air intake part 312 is arranged on the air intake plate body 31 at a position corresponding to the second panel 33, so that part of the oil smoke can enter the range hood through the gap formed between the second panel 33 and the air intake plate body 31 and the second air intake part 312, because the second air intake part 312 is hidden at the back of the second panel 33, the second air intake part 312 cannot be exposed when a user uses the range hood, and the neat and beautiful appearance of the product can be ensured; meanwhile, the second air inlet portion 312 can achieve an auxiliary air inlet function, the air inlet area of the range hood can be increased, the air inlet efficiency of the range hood is improved, and the rotating speed of a fan can be reduced by increasing the air inlet area under the condition of the same air inlet amount, so that the purpose of noise reduction is achieved. The problem that in the prior art, the range hood discharges oil smoke fast, the outdoor air quantity discharged in unit time is improved, the rotating speed of a fan of the range hood is improved, noise is increased, and user experience is influenced is solved.

Moreover, after the second air inlet portion 312 is arranged, oil drops condensed at the position of the second air inlet portion 312 can slide into the oil cup 40 from the back of the second panel 33, so that oil drops can be conveniently collected, and meanwhile, the attractiveness of the product is not affected.

According to the range hood provided by the application, after the fan assembly 20 starts to work, the first air inlet portion 311 and the second air inlet portion 312 simultaneously supply air, which is equivalent to simultaneously supply air to both sides of the fan assembly 20, so that air flows on both sides of the fan assembly 20 can be balanced, and noise caused by turbulence of the air flows in the machine body 10 is avoided.

Finally, it should be noted that: the above embodiments are merely illustrative of the present application and are not intended to limit the present application.
