Abstract
The utility model discloses a filter screen for a range hood. The filter screen for the range hood is characterized by comprising a plurality of ventilated faces which are arranged in parallel from side to side; each ventilated face is a concave face which is provided with high left side and right side and low middle part, and a plurality of meshes are formed in two side faces of the ventilated face; a drainage groove is formed in the middle concave part of the ventilated face, and the concave depth of the ventilated face is gradually increased from the front end to the rear end. The parallel ventilated faces which are provided with two high sides and low middle parts are arranged and the meshes are formed in the inclined faces of the ventilated faces, so that the filter screen has large area for causing cooking fumes to pass compared with a plane filter screen, and the fume exhausting efficiency is improved. Moreover, the cooking fumes can collide with the side faces of the ventilated faces for multiple times during passing, thus being beneficial to condensing grease onto the ventilated faces to flow into an oil cup along the drainage grooves. The multiple times of collision of the cooking fumes and the filter screen can disperse cooking fume flows, and the rectifying effect of cooking fumes passing though the filter screen is improved.
Description
Technical field
The utility model relates to a kind of range hood, especially a kind of filter screen for range hood.
Background technology
Existing lampblack absorber, no matter be top suction type or side-suction type, is all provided with filter screen at the air inlet place of blower fan conventionally, the effect separating to strengthen oil smoke.And current conventional filter screen, as the disclosed a kind of lampblack absorber automatically cleaning filter screen of Chinese patent application that application number is 201210472911.5, is provided with filter screen eye on filter screen; The disclosed a kind of oil screen for European-style range hood of Chinese patent application that and for example application number is 200810244564.4, offers some air admission holes in oil network, be low, the middle high shape in following peripheral; The disclosed a kind of oil screen of range hood of Chinese patent that and for example application number is 201020202030.8, is included as rectangular tabular outer oil network and interior oil network, is respectively arranged with circular mesh on it.
These above-mentioned filter screens, although gather mesh on filter screen, but the area of air intake is still less, causes intake sharply to decline; Oil smoke directly enters air inlet through mesh, and the time of stop is short, and contact area is few, and the separating effect of grease and flue gas is undesirable, and not obvious to the rectified action of flue gas.
Utility model content
Technical problem to be solved in the utility model is the problem existing for above-mentioned prior art, and a kind of filter screen for range hood is provided, and can improve the effect of smoke exhaust efficiency, oil smoke separation and rectification.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of filter screen for range hood, it is characterized in that, comprise the ventilating surface that multiple left and right are arranged in juxtaposition, described ventilating surface is high, the middle low concave surface in the left and right sides, on two sides of described ventilating surface, offer multiple mesh, recess in the middle of described ventilating surface forms drainage trough, and the recessed degree of depth of described ventilating surface is increased to the back-end gradually by front end.
Fixing for the ease of with lampblack absorber body, described ventilating surface periphery is provided with frame, the side top of two ventilating surface of the left and right sides extends to respectively frame, between the rear end of described drainage trough and frame, there is in the vertical gap, grease after separation can flow into lubricating cup from this gap, thereby and on frame, can be arranged on fixture filter screen and lampblack absorber body are fixed.
For the ease of filter screen is processed, parallel in described frame, compartment of terrain is furnished with the connection strap that extend multiple front and back, middle each ventilating surface is between two connection straps, the ventilating surface of the left and right sides is between connection strap and frame, and two side top of described ventilating surface extend to connection strap or the frame of corresponding side.
Compared with prior art, the utility model has the advantage of: by low ventilating surface between the senior middle school of arranged side by side multiple both sides is set, on the inclined-plane of ventilating surface, offer mesh, make the filter screen of filter screen opposite planar formula there is the larger area passing through for oil smoke, improve smoke exhaust efficiency, and oil smoke by time can there is multiple impacts with the side of ventilating surface, contribute to grease to be condensate in ventilating surface, flow into lubricating cup along drainage trough, and the multiple impacts of oil smoke and filter screen, oil smoke air-flow can be broken up, improve oil smoke by the rectification effect of filter screen.
Accompanying drawing explanation
Fig. 1 is the structural representation of filter screen of the present utility model;
Fig. 2 is the structural representation (oppositely) of filter screen of the present utility model;
Fig. 3 is the application schematic diagram of filter screen of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Referring to Fig. 1 and Fig. 2, a kind of filter screen for range hood, comprise rectangular frame 1, four angles of frame 1 are fillet, frame 1 is interior parallel, interval is furnished with the connection strap 2 that extend multiple front and back (during take normal operating condition towards one end of user as front), between two connection straps 2, be provided with ventilating surface 3, 3 of the outermost ventilating surface in left and right are between connection strap 2 and frame 1, it is high that ventilating surface 3 is the left and right sides, middle low concave surface, it is the connection strap 2 that both sides peak extends to respectively corresponding side, the minimum point of medial concavity is positioned at the centre of two connection straps 2, and the peak that is positioned at the outer lateral side of outermost two ventilating surface 3 in left and right extends to respectively on frame 1.
The side of two inclinations of ventilating surface 3 can be arcwall face or plane, middle recess forms drainage trough 31, on each side, offer multiple parallel, spaced apart by side top to concave surface extend, the mesh 32 of the strip being extended to drainage trough 31 by connection strap 2.
The recessed degree of depth of ventilating surface 3 is increased to the back-end gradually by front end, and the recess location in the middle of ventilating surface 3 reduces to the back-end gradually from front end, and from the rear side of filter screen, the rear end of ventilating surface 3 forms multiple horizontal w shape or waveforms.Thus, drainage trough 31 is tilted to the back-end gradually by front end, in rearward end, between drainage trough 31 and frame 1, has in the vertical gap, so that isolated grease flows in the lubricating cup that is located at filter screen below from this gap.
Referring to Fig. 3, the embodiment of an application of filter screen of the present utility model, for top-sucking kitchen ventilator, be arranged on the air inlet of the exhaust fume collecting hood 4 of range hood, between exhaust fume collecting hood 4 and smoke deflector 5, can be fixing by the modes such as installing hole and exhaust fume collecting hood 4 is set on frame 1, the below of exhaust fume collecting hood 4 is provided with the lubricating cup 6 of bar shaped, and filter screen concentrates in lubricating cup 6 with the grease inflow separating on smoke deflector 5.
