Description
Technical field
The present invention relates to a kind of range hood, particularly a kind of used for range hood oil net arrangement.
Background technology
At present, the oily net arrangement that is used for range hood mainly contains following several:
First kind: the outer oil guidance column that adopts, internal layer adopts fine and close screen pack form, and this kind oil-net structure causes fine and close screen pack to stop up easily, and causes oily net oil dripping easily under the not enough situation in oil net angle of inclination;
Second kind: double-deck tile type structure (as shown in Figure 1), this kind oil-net structure air intake resistance is very big, cause the range hood air quantity to be difficult to promote, and noise is very big;
The third: bilayer is " U " shape oil-net structure (as shown in Figure 2) in the same way, and this kind oil-net structure is semicircle thin-slab structure, when air-flow through out-of-date, can produce a large amount of eddy current at the back side of " U " shape, cause range hood air draught decrease in efficiency, and noise rises;
The oily net of range hood also is the mouth of dispersing of range hood interior noise as the air inlet of range hood simultaneously, and above oil-net structure does not all have the sound-deadening and noise-reducing function, causes range hood complete machine noise to reduce.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of used for range hood oil net arrangement, this oil net arrangement filtering oil smoke is effective, air draught efficient height, noise is low.
