Abstract

The utility model relates to a solid body with two air intakes and two tilted angles at bottom, is one of the main components of an oil fume extractor, which comprises a cover plate A and a smoke-gathering hood B that is punched by a metallic plate. On the cover plate A, a notch 1 and a circumferential rim 2 are provided; and for the two side rims, from the rear to front and from front to rear, tilted angle alpha and beta are provided; on the smoke-gathering hood B, a baseplate 4, a boss 5, two holes 6, and a turnup edge 7 with a tilt same with that of the rim 2 are provided; then the smoke-gathering hood B is connected with the cover plate A and welded with the cover plate A, still then buffing and polishing are carried out. The utility model removes any seam occurred after assembling the smoke-gathering hood and the cover board, so that the whole unit becomes more sturdy and graceful, and easy to clean; in addition the fume-extraction force of the oil fume extractor is high, the smoke-gathering effect is very good, and the noise is low.

Description

Two inclination angles, two air intakes bottom surface integral body

One, technical field

The utility model relates to a kind of fuselage of range hood, two inclination angles, specifically two air intake bottom surface integral body.

Two, background technology

At present, the frame assembly exhaust fume collecting hood of range hood and lamina tecti, left and right sides cover plate are all with independence, split-type structural design, manufacturing, assembling both at home and abroad, therefore the junction exists either large or small slit, these slits have not only influenced the attractive in appearance of range hood appearance, the greasy place of sheltering evil people and countenance evil practices that provides more is provided, is made users bring great inconvenience to the cleaning maintenance of range hood at ordinary times.

Three, summary of the invention

The technical scheme of the two inclination angle integral body technical issues that need to address in the two air intake bottom surfaces of the utility model and proposition is: the frame assembly exhaust fume collecting hood of range hood and cover plate are consisted of an integral body, remove the slit that former fuselage is occurred because of assembling, make fuselage more attractive in appearance, firm, maintenance washes is also more convenient.Specific embodiments is: get two metallic plates, a metallic plate is processed into a cover plate, on the cover board process a breach, and have the frame of height≤200mm, both sides frame that inclination alpha≤70 ° and β≤85 ° are arranged from back to front, from front to back at four edge breaks of cover plate; On another metallic plate, stamp out and comprise base plate, boss, two holes, and four edge breaks have turning edge (afterwards turn edge and can process with exhaust fume collecting hood integral body, also can load onto separately) of height≤200mm and make both sides turn edge from back to front, have from front to back inclination alpha ₁With β ₁, and make α ₁With α, β ₁The exhaust fume collecting hood that equates respectively with β.Then exhaust fume collecting hood with after cover plate is connected again the method with welding make it to become the seamless non-removable integral body in junction, remove uneven place with milling tools again, at last with its surface finish until the vestige of eliminating welding fully.The integral body of the range hood through being processed into like this is more solid more attractive in appearance than original fuselage, the faster convenience of maintenance washes range hood, and range hood hold together that cigarette is effective, noise is also little.

The technical scheme of two inclination angles, the two air intake bottom surfaces of the utility model integral body is: it comprises and has the cover plate A that breach 1 and four edge breaks have frame 2, by base plate 4, and boss 5,6, four limits, two hole, the 7 exhaust fume collecting hood B that form that turn edge; Become an integral body through welding, polishing, polishing again after it is characterized in that exhaust fume collecting hood (B) and cover plate (A) being connected, and frame 2 with turn edge height≤200mm of 7; The both sides frame has inclination alpha≤70 ° and β≤85 ° from back to front, from front to back; Exhaust fume collecting hood B both sides turn edge from back to front, have from front to back inclination alpha ₁With β ₁, and make α ₁With α, β ₁Equate respectively with β, this fuselage has not only been eliminated the slit that was originally occurred by parts such as exhaust fume collecting hood and cover plate assembling back, make it more solid attractive in appearance, it is more convenient to clean, and because the air intake place has two holes, therefore exhaust fume collecting hood is shaped on two inclination angles, increased the incoming air area of range hood, significantly improved range hood to the extracting force of oil smoke simultaneously range hood hold together that cigarette is effective, noise is also little.

Four, description of drawings

Fig. 1 is two inclination angles, the two air intake bottom surface of the utility model integral body decomposition charts.

Among the figure: A, cover plate; 1, breach; 2, frame; B, exhaust fume collecting hood; 4, base plate; 5, boss; 6, two holes; 7, turn edge; α, β, α ₁, β ₁The inclination angle.

Fig. 1 illustrates:

The utility model is an overall structure, and the exhaust fume collecting hood B that cover plate A that it is stamped to form by the block of metal plate and block of metal plate are stamped to form forms; On cover plate A, be processed with breach 1, four edge break the frame 2 of height≤200mm is arranged; And make the both sides frame that inclination alpha≤70 ° and β≤85 ° be arranged from back to front, from front to back; Be processed with base plate 4 on the exhaust fume collecting hood B, what boss 5, two holes 6, four edge breaks had a height≤200mm turns edge 7, and makes both sides turn edge from back to front, have from front to back inclination alpha ₁With β ₁, and make α ₁With α, β ₁Equate respectively with β.

Fig. 2 is two inclination angles, the two air intake bottom surface of the utility model integral body outline drawings.

Among the figure: A, cover plate; B, exhaust fume collecting hood.

Fig. 2 illustrates:

After cover plate A and exhaust fume collecting hood B shape, cover plate A is connected up and down with exhaust fume collecting hood B, method with welding makes it to become seamless, the non-removable integral body in junction again, at last its surface finish, polishing is become two inclination angles, the two air intake bottom surface of the utility model integral body until eliminating the vestige of welding fully.

Five, the specific embodiment:

At first according to the development size of cover plate A block of metal plate under shearing on the plate shearing machine, and on lathe, process the frame 2 of breach 1 and four limit height≤200mm, and make the both sides frame that inclination alpha≤70 ° and β≤85 ° be arranged from back to front, from front to back; Again according to the development size of exhaust fume collecting hood B block of metal plate under shearing on the plate shearing machine, on hydraulic press, suppress boss 5, what process two holes 6 of boss 5 and four limit height≤200mm on lathe after cutting edge turns edge 7, and makes both sides turn edge from back to front, have from front to back inclination alpha ₁With β ₁, and make α ₁With α, β ₁Equate respectively with β.Then cover plate A with after exhaust fume collecting hood B is connected up and down again the method with welding make it to become one, at last through polishing, polishing, until eliminating the vestige of welding fully, thereby become two inclination angles, the two air intake bottom surfaces of the utility model integral body.
