Abstract

The invention discloses a range hood. The range hood comprises a fan frame and a fan system arranged in the fan frame, wherein the fan system comprises a motor, the motor is fixedly connected with therear side wall of the fan frame through a motor support, and a damping assembly is arranged at the joint between the motor support and the fan frame. The range hood is characterized in that the damping assembly comprises a hollow outer support and a damping pad arranged on the inner side of the outer support, a mounting hole is formed in the rear side wall of the fan frame, the outer support comprises a buckling portion which penetrates through the mounting hole of the fan frame and is clamped, and a support portion, and the support portion extends from the end portion, outside the fan frame,of the buckling portion to the rear portion of the fan frame so as to be used for supporting an external installation foundation. Compared with the prior art, the range hood has the advantages that the support portion which can be used for supporting the external installation foundation is arranged on the damping assembly, so that supporting is provided for the rear side face of the fan frame, and vibration of the fan frame in the large-plane direction is effectively inhibited.

Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a range hood. Background technique [0002] 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 improve the effect of the range hood, a common practice is to increase the air volume of the range hood, which causes the vibration problem of the whole machine to become more and more obvious, and the vibration and the noise caused by it brin...
