Abstract

The invention relates to the technical field of intelligent household appliances, and discloses a range hood. The range hood comprises a first top plate, side plates, a back plate, a face plate and a first flow guide plate; a smoke outlet is formed in the first top plate; the upper ends of the side plates are connected with the first top plate; the upper end of the back plate is connected with the first top plate, and the side ends of the back plate are connected with the side plates; the face plate and the back plate are oppositely arranged, the side ends of the face plate are connected with the side plates, and a smoke inlet is formed in the lower portion of the face plate; the first flow guide plate extends from the side plates to the first top plate; and a smoke collecting cavity is defined by the first surface of the first flow guide plate, the side plates, the back plate and the face plate, and smoke is discharged from the smoke outlet. By arranging the first flow guide plate, the situation that due to the fact that smoke impacts on a vortex area generated at the intersection of the first top plate and the side plates, large smoke flow losses are caused is avoided, under the condition that the same smoke flow is achieved, the rotating speed of a fan is reduced, and the running noise of the fan can also be reduced by reducing the rotating speed of the fan; and noise generated due to the fact that smoke impacts on the vortex area is also reduced.

Description

technical field [0001] The present application relates to the technical field of smart home appliances, for example, to a range hood. Background technique [0002] With the improvement of people's material living standards, the demand for protection from cooking fume is also increasing, and the range hood has gradually become an indispensable household appliance for purifying the kitchen environment. [0003] The existing range hood still has the problem of high noise when it is in operation. There are many reasons for the noise generated when the range hood is running, including the noise generated by the various components when the range hood is running, such as the noise generated when the motor is running; it also includes the noise generated by the flue gas circulation; for the problem of the operating noise of the range hood, currently , the method of setting sound-absorbing materials on the inner wall of the smoke collecting cover of the hood is often used to reduce ...
