The lampblack is pumped in from the periphery; meanwhile, the flow guide groove of the shell adopts a concave-convex shape and the lampblack in a high-speed movement state meets the concave-convex bending shapes, then the moving direction of the lampblack is changed, and collision and vortex are generated, and grease and small particles in gas flow are attached on the flow guide groove, so that the lampblack separation is well realized and the lampblack collision rate is improved; the flow guide groove is combined with the filtering net so that the lampblack separation efficiency is improved.
Description
Technical field
The utility model relates to the applied technical field that manufactures and designs of cooking apparatus, is a kind of design and manufacturing technology that relates to range hood for kitchen use, specifically refers to a kind of range hood cover plate of separated oil smoke.
Background technology
Existing range hood cover plate mainly adopts orifice-plate type filter type, outputs a plurality of circles or oblong pore on flat board.When the oil smoke of high-speed motion passes through cover plate, oil smoke is blocked, and plays certain filtration.
Though this orifice plate can stop a small amount of oil smoke, it is inner that most of oil smoke directly enters into range hood movement, and flare is easily scurried into simultaneously, and wind loss is large, and oil smoke separative efficiency is low.
Utility model content
The purpose of this utility model is to overcome the defect of above-mentioned prior art, and a kind of range hood cover plate of efficient separated oil smoke is provided.
For reaching this object, the utility model by the following technical solutions:
A range hood cover plate for separated oil smoke, described range hood cover plate comprises shell and the oil fume separation plate that shape is identical; Described shell is provided with guiding gutter, and oil fume separation plate is provided with screen pack; Between described shell and oil fume separation plate, be parallel to each other and leave gap; The vertical depth of the clearance distance≤guiding gutter between described shell and oil fume separation plate.
Oil smoke, from the surrounding suction of range hood cover plate described in the utility model, first carries out oil smoke separation through the screen pack on oil fume separation plate, enters subsequently in the gap between oil fume separation plate and shell.Oil smoke, under the state of high-speed motion, runs into guiding gutter and can change its direction of motion, thereby produces collision and eddy current, grease, molecule in air-flow is all attached on guiding gutter, thereby has improved well oil smoke collision rate and realized oil smoke separation.
The structure that the utility model adopts guiding gutter and screen pack to combine, has improved oil smoke separative efficiency.
The utility model is parallel to each other shell and oil fume separation plate to place and leave gap, and this gap is as the passage of oil smoke high-speed motion.The placement form being parallel to each other, windage is little, and profile is also more attractive in appearance.
The utility model limits the vertical depth of the clearance distance≤guiding gutter between shell and oil fume separation plate, its object guarantees that oil smoke strengthens collision rate and the intensity of oil smoke and the concavo-convex baffle plate thing of guiding gutter under the state of high-speed motion between shell and oil fume separation plate, improves oil smoke separative efficiency.If the clearance distance between shell and oil fume separation plate is greater than the vertical depth of guiding gutter, oil smoke declines with the collision probability of the concavo-convex baffle plate thing of guiding gutter in motion process, and oil smoke separative efficiency is low.
Described guiding gutter be shaped as at least one spill.Described at least one spill refers to that described guiding gutter can be the structure of single spill or the arrangement of a plurality of spill.
Preferably, described guiding gutter is shaped as concavo-convex being connected.Concavo-convex joining guiding gutter shape is more complicated, and bending part is more.Oil smoke runs into concavo-convex bending part and changes successively the direction of motion under the state of high-speed motion, more easily produces collision and eddy current.
The cross section of described guiding gutter is the distortion of spill or concaveconvex shape.Those skilled in the art can carry out Choice and process according to actual needs.
Preferably, described spill is U-shaped or V-arrangement.
Preferably, the distortion of described concaveconvex shape is S shape or W shape.
Compare with prior art scheme, the utlity model has following beneficial effect:
1, oil smoke is from surrounding suction, guiding gutter on shell adopts concave-convex simultaneously, oil smoke runs into concavo-convex bending and changes successively the direction of motion at the state of high-speed motion, thereby produce collision and eddy current, grease, molecule in air-flow are all attached on guiding gutter, thereby realize well oil smoke separation, have improved oil smoke collision rate;
2, adopt guiding gutter and screen pack to combine, improved oil smoke separative efficiency.
