Fan assembly and range hood

Abstract

The invention provides a fan assembly and a range hood. The fan assembly comprises an impeller, a motor and a rotary filter screen arranged at an air inlet, and further comprises an oil guiding piece,wherein the oil guiding piece is arranged on one end face, far away from the impeller, of the rotary filter screen, at least one part of the oil guiding piece is arranged to close to the circle center part of the rotary filter screen, the oil guiding piece is provided with an oil guiding part in contact with lampblack, and at least a part of the oil guiding part protrudes towards the air inlet direction. Under the action of the impeller, the lampblack at the rotary filter screen flows in an oil drop state in the adsorption process, and is guided to be away from the center of the rotary filterscreen at the oil guiding piece, oil drops far away from the center of the rotary filter screen are large in centrifugal force, the oil drops can be well thrown out to the periphery, and the better lampblack separation effect is achieved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a fan assembly and a range hood. Background technique [0002] With the development of society, the range hood has become an essential kitchen appliance in urban living kitchens. However, the range hood has the problem of inconvenient cleaning. [0003] In the prior art, a high-speed rotating filter screen is used to intercept the lampblack to solve the cleaning problem of the range hood. The rotating filter screen is arranged on the side of the impeller close to the air inlet, and the radial direction of the rotating filter screen is perpendicular to the axial direction of the impeller. After the rotating filter screen rotates, it can prevent the hood from flowing into the inside of the impeller, thereby preventing the internal core components from being troubled by oil fumes. [0004] The current rotating filter screens all use single-sided or double-layer filter ...

AI Technical Summary

Problems solved by technology

[0004] The current rotating filter screens all use single-sided or double-layer filter screens. The filter screen intercepts and gathers the grease in the oil fume under high-speed rotation. When the amount of accumulation reaches a certain amount, it is pulled away from the filter screen by centrifugal force. The centrifugal force in the area with a smaller radius is smaller than that of the outer ring, and the oil intercepted by the inner ring is subjected to a smaller centrifugal force. Before being thrown out by the centrifugal force, it is re-sucked into the impeller by the air inlet, thereby reducing the grease separation of the rotating filter. degree, thus affecting the cleaning effect
