Abstract
A filter screen board of a range hood comprises a filter screen frame and a filter screen which is embedded inside the filter screen frame, and the filter screen frame is formed by bending one frame bar. The filer screen board of the range hood is characterized in that the cross section of the frame bar is formed by joining two ends of a connecting edge with a soleplate and a panel, the soleplate is vertically connected with a connecting plate at an angle of 90 degrees, and the panel and the connecting plate form an opening which is more than 135 degrees. The bending positions of the connecting plate and the panel are provided with inward-sunken grooves. The filter screen board of the range hood has beneficial effects that (1) the filter screen frame is previously fixed and molded, so that the filter screen frame is uneasy to deform and break when a filter screen is installed; (2) a novel filter screen installation method is adopted, so that the filter screen is convenient to install and is tightly clamped by the filter screen frame, and the working noise can be reduced; and (3) the structure is simple, the production procedures are fewer, the efficiency is high, and the cost is low.
Description
Technical field
The utility model relates to a kind of lampblack absorber technical field, specifically is a kind of lampblack absorber screen pack and production method thereof.
Background technology
Previously used lampblack absorber generally all is through the built-in fans in the lampblack absorber oil smoke to be discharged to the open air, this mode of removing oil smoke; Do not reach in the oil smoke separating of oil and cigarette, do not have the effect of environmental protection, and lampblack absorber is when the eliminating oil smoke; Oil in the oil smoke just stick on the fan blade of lampblack absorber with gas exhaust piping in; Make whole lampblack absorber inner product expire greasy dirt, clean very difficulty, even more serious is accumulates to when a certain amount of when the greasy dirt in the lampblack absorber; Greasy dirt under the gravity effect and flow backwards back indoor, thereby influence indoor sanitary condition.And greasy dirt sticks on the lampblack absorber and the corrosion lampblack absorber for a long time, the destruction of not only having caused outward appearance, and increased potential safety hazard in use, shortened the service life of lampblack absorber.Therefore Chinese patent number 200820122133.6 lampblack absorber screen packs by name propose the power solution; It is to be provided with screen pack in the inlet scoop of lampblack absorber, it is characterized in that: described filtering oil smoke web plate comprises frame and screen pack, and described screen pack is connected on the frame; Described frame is to fix through bending of a frame bar and frame bar two ends to form; This frame bar is provided with breach at bending part, has groove in the described frame, makes frame have only an interface thus.The production method of this web plate is earlier frame to be left open-ended on one side, and filter screen is inwardly inserted from this opening part, in the groove that filter screen is embedded in offer in the frame.After in the complete insertion groove of filter screen, remaining one side bending is sealed.Because this special installation method makes it also have following shortcoming: 1) because frame is the aluminium making, and plasticity and toughness are relatively poor, after frame bending once; Just be formed with crackle in the bending place, if do not finalize the design, the frame bending place is fracture easily just; So when filter screen is installed, need extreme care, if exert oneself a little, frame can rupture; Installation brings inconvenience to filter screen, and percent defective is high.2) filter screen needs manual work in groove, to insert installation, and installation difficulty is big, and the power consumption time is long, inefficiency.3) gap is bigger between filter screen and groove, and filter screen is loosening easily, and particularly when lampblack absorber smoking was worked, the filter screen vibrations were big, cause noise bigger, drawbacks such as frame wearing and tearing.
The utility model content
The purpose of the utility model is to provide a kind of simple in structure to the existing defective of existing known technology product, and production process is few, and efficient is high, and cost is low, lampblack absorber screen pack and production method thereof that filter screen frame clamping filter screen is tight.
The purpose of the utility model is to realize like this; A kind of lampblack absorber screen pack; Comprise filter screen frame and be embedded in the screen pack in the filter screen frame that described filter screen frame is formed by a frame bar bending, it is characterized in that: described frame bar cross section connects base plate by the fillet two ends and panel constitutes; Be for 90 vertical connections of degree between described base plate and connecting plate, be the opening shape of spending between panel and connecting plate greater than 135.
The bending place of described connecting plate and panel is provided with the groove that caves inward.
Described groove is an arc groove, and the arc groove radius is 1/2 to 1/3 of a connecting plate thickness.
Also be bent with hush panel on described panel and the base plate.
Described hush panel height is about 3-4 times of connecting plate thickness.
The beneficial effect of the utility model is: 1) filter screen frame predetermined fixed moulding makes filter screen frame not yielding and fracture when filter screen is installed.2) the filter screen installation method of novelty makes filter screen easy for installation, and filter screen frame clamping filter screen is tight, reduces work noise.3) simple in structure, production process is few, and efficient is high, and cost is low.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to explain.As shown in the figure: a kind of lampblack absorber screen pack; Comprise filter screen frame 1 and be embedded in the screen pack 9 in the filter screen frame; Described filter screen frame 1 is formed by a frame bar bending; It is characterized in that: described frame bar cross section connects base plate 3 by fillet 2 two ends and constitutes with panel 4, and described base plate 3 was for 90 vertical connections of degree with 2 of connecting plates, and 2 of panel 4 and connecting plates are the opening shape greater than 135 degree.
Described connecting plate 2 is provided with the groove 5 that caves inward with the bending place of panel 4.
It is characterized in that described groove 5 is arc groove, the arc groove radius is 1/2 to 1/3 of connecting plate 2 thickness.
Also be bent with hush panel 6 on described panel 4 and the base plate 3.
Described hush panel 6 highly is about 3-4 times of connecting plate 2 thickness.
Operation principle: the filter screen moulding is made into section bar in advance; Section bar the bending place of base plate 3 and panel 4 shear jaggedly 8, a wherein end of frame bar is provided with and connects scrap (bridge) 7, the bending back is fixed into the quadrangle empty frame shape by fixing closing in of scrap (bridge); After being placed on screen pack 9 on the base plate; Be placed in the mould and push, panel 4 is bent into connecting plate is 90 degree, hush panel 6 is clamped in screen pack 9 surfaces.
Be provided with the groove 5 that caves inward in the bending place of connecting plate 2 and panel 4 in this case; Groove 5 makes that the thickness of panel 4 is thinner relatively with respect to other positions; Therefore after filter screen frame 1 moulding; Be placed on when pushing in the mould, thus panel 4 more easy deformation be bent into connecting plate 2 be 90 the degree.Owing to use in advance the fixedly filter screen frame 1 of moulding of four limits, so the filter screen frame structure is more firm, is unlikely to when the installation filter screen, to be fractureed.And 2 of panel 4 and connecting plates are the opening shape greater than 135 degree; Therefore around filter screen frame fixedly after the moulding, filter screen frame 1 upper surface is opening-like, can let filter screen 9 directly put into filter screen frame; Place in the mould then and push; Panel 4 is bent into connecting plate is 90 degree, hush panel 6 is clamped in fixedly filter screen of screen pack 9 surfaces, avoids filter screen because of the noise that the insecure vibration that brings is sent is installed.
