Oil flinger for blower of range hood

Abstract

The invention discloses an oil flinger for a blower of a range hood. The oil flinger comprises an oil flinger main body and is characterized in that the surface of the oil flinger main body is provided with arc-shaped grooves which are in central symmetry and are in array arrangement; each groove extends in the radial direction; the surface of the disc main body is provided with at least two layers of groove arrays;each layer of groove array is in a circular ring shape; spokes are formed among the adjacent grooves in each layer on the surface of the oil flinger main body. By virtue of radially-extending arc-shaped grooves, when contacting with the oil flinger main body, oil drops can flow from inside to outside smoothly, a greater centrifugal force is obtained and then efficiency non-fluid oil centrifugal separation is realized; furthermore, multiple layers of groove arrays are formed, so that on the one hand, the rigidity of the oil flinger is improved, on the other hand, the optimal width size is obtained by freely distributing the grooves and spokes in each layer according to the actual fume concentration distribution characteristic after specifically selecting a blower system without influence of the grooves in the other layers, and the filtration effect is improved as much as possible.

Description

technical field [0001] The invention relates to a range hood, in particular to an oil flinger used for a fan of the range hood. Background technique [0002] With the continuous improvement of people's awareness of environmental protection and health, people pay more and more attention to the environmental protection indicators of range hoods. The range hood has an important performance index - grease separation. The stronger the ability of the range hood to filter the oil in the oil fume, the higher the separation degree of oil. [0003] At present, traditional range hoods generally use porous filter screens to intercept oil fume, and filter the oil fumes of the range hood by colliding with the oil fume gas to decelerate and condense. For example, the Chinese patent application number 201420296349.X discloses a rotary grease separation filter for range hoods. The center hole of the filter disc is installed on the rotating shaft of the motor through a sleeve and a knob. Th...

Problems solved by technology

However, the manufacturing process of this kind of filter screen structure is very complicated, and the winding of the steel wire can only be in a straight line between two fulcrums, similar to the staggered structure of straight spokes of bicycle tires, which affects the filtering capacity on the one hand, and on the other hand , the dense steel wires rotate and produce a lot of noise, the sound quality is degraded, and cleaning is also very troublesome
