Problems solved by technology

[0002] In the existing range hoods, the filter screen devices are generally flat or cup-shaped. Due to the limitation of the cross-sectional size of the air inlet of the range hood fan cabinet and the consideration of the appearance design, the ventilation holes of the filter screen device The area is generally small
The size of the air hole area of ​​the filter device will not only affect the filtering, condensation and separation effects of oil fume, but also affect the exhaust air volume of the range hood

Embodiment 1

[0023] Such as Figure 1~3 As shown, the concave-convex structure filter device of the range hood includes at least a concave-convex structure filter 1 and a filter frame 2; the concave-convex structure filter is a metal perforated plate structure with strip-shaped holes on the surface; its concave-convex structure It is formed by connecting a plurality of strip-shaped convex sections 101 with the adjacent plane section 102. The section of the convex section is rectangular. Flanges 103 are respectively provided on the left and right sides of the filter screen. Mounting holes 104 are respectively provided on the plane section near the edge.

[0024] The filter frame 2 includes an upper frame and a lower frame. The cross section of the frame is groove-shaped. The frame is formed by connecting front and rear side plates 201, 202 and a bottom plate 203. A top plate 204 is also connected to the top of the front side plate. The rectangular groove 205 corresponding to the raised sectio...

Embodiment 2

[0027] There is no figure. The only difference from Embodiment 1 is that the cross section of the raised section of the filter screen is in the shape of an arc, and the top plate of the filter screen frame is provided with an arc-shaped groove corresponding to the raised section of the mesh wall.

Abstract

The invention relates to a concave-convex structure filter screen device of a range hood. The concave-convex structure filter screen device at least comprises a concave-convex structure filter screen and a filter screen frame, wherein a concave-convex structure of the concave-convex structure filter screen is formed by connecting a single or a plurality of strip-type convex sections with adjacent planar sections or adjacent curved sections, by connecting a single or a plurality of ring-shaped convex sections with the adjacent planar sections or the adjacent curved sections, or by arranging a single or a plurality of convex closures or lug bosses on a plane or a curved surface according to a certain rule; the concave-convex structure filter screen at least comprises any structure of a metal pore plate filter screen, a metal screen plate filter screen and a metal gauze filter screen, and a metal filter plate structure comprising flanging ventilation holes; the concave-convex structure filter screen is large in surface area and ventilation area, and is favorable for oil smoke purification and reduction of air loss; the three-dimensional ventilation holes of the concave-convex structure filter screen are favorable for separation, attachment, condensation and purification of oil smoke; and the concave-convex structure filter screen can ensure that the structural rigidity of the filter screen is multiplied, and is favorable for reducing the material consumption.

Description

Technical field [0001] The invention relates to a range hood, in particular to a filter device of the range hood. technical background [0002] The filter device of the existing range hood is generally flat or cup-shaped. Due to the limitation of the cross-sectional size of the air inlet of the fan cabinet of the range hood and the consideration of appearance design, the ventilation hole of the filter device The area is generally small. The size of the ventilation hole of the filter device will not only affect the filtering, condensation, and separation effects of oil fume, but also affect the air volume of the range hood. Summary of the invention [0003] The present invention is proposed in response to the above-mentioned shortcomings, and its purpose is to greatly increase the surface area of ​​the range hood filter device by adopting a concave-convex structure filter device without changing the cross-sectional size of the air inlet of the range hood fan cabinet. The ventilat...
