Abstract

The utility model relates to an exhaust hood trilateral extroversion fenestration integrated machine body, which is one of the main spare parts of the exhaust hood. The machine body comprises a cover plate A that is made by stamping the completely stainless steel plate and a smoke-collecting helmet B. A gap 1, a window 3 and a frame 2 are all positioned on the cover board A. Both the front frames and the left and right frames of the cover board A is with extroversion angle of smaller than or equal to 70 degrees. A base plate 4, a flange 5, a center hole 6 and a turned edge with the same extroversion angle as that of the frame 2 are processed and arranged in the smoke-collecting helmet B. After the smoke-collecting helmet is set inside the cover plate A from the bottom of the cover plate A, the smoke-collecting is welded, grinded and polished and then the integrated machine body is completed. The integrated machine body eliminates the gaps around the machine body that is originally made by the assembling of the smoke-collecting cover and the cover plate. Therefore, the machine body becomes more compact and beautiful and the maintenance and cleaning also become much faster and more convenient. Resulting from that the front frame and the left and right frames are extroverting, the upper cross section of the smoke-collecting cover B as a whole body with the machine body is smaller than that of the bottom part, and when in releasing, the flow rate of upper part of the exhaust hood is faster than that of the bottom, thereby improving the releasing strength of the absorption force of the exhaust hood.

Description

Range hood three limit flare fenestration integral bodies

One, technical field

The utility model relates to a kind of fuselage of range hood, specifically range hood three limit flare fenestration integral bodies.

Two, background technology

At present, domestic range hood industry competition is more and more fierce, and competition focal point is a cost performance, and who can produce the best product of performance with the cost of minimum, and who just can establish oneself in an unassailable position forever.A few days ago, I am changed into the major part exhaust fume collecting hood of range hood the kitchen hood exhaust fume collecting hood (patent No. 02288029.1) of seamless monolithic construction by split-type structural, after using, find, though having, this exhaust fume collecting hood itself do not connect the scar weld seam, but when the fuselage of assembling range hood, still need assemble a cover plate above it, therefore around the fuselage edge of range hood, leave the slit inevitably, not only influenced attractive in appearancely, brought inconvenience also for usual cleaning maintenance.Simultaneously, this exhaust fume collecting hood is not very good for the congregational rate of the oil smoke that culinary art produces yet, and cardinal symptom shows as the extracting force of oil smoke not enough.

Three, summary of the invention

The technical scheme of the utility model range hood three limit flare fenestration integral body technical issues that need to address and proposition is: the slit all around, fuselage edge of removing range hood, make complete machine more attractive in appearance, more firm, maintenance washes is also more convenient, and increases the extracting force of range hood to oil smoke.Specific embodiments is: get two corrosion resistant plates, processing one breach on a corrosion resistant plate, the place ahead of breach are opened a window (have the window lid, can be convenient to the maintenance to switch), all around folding has frame (back frame approximate turns edge), the cover plate that the frame of its front and the right and left leans outward; On another corrosion resistant plate, strike out than cover plate appearance and size smaller comprise base plate, boss, the hole, center, all around turn edge, turning edge of its front and the right and left equates that with the front of cover plate and the frame flare angle of the right and left (an approximate frame afterwards turns edge, it can process with exhaust fume collecting hood integral body, also can load onto separately) exhaust fume collecting hood.Then exhaust fume collecting hood is become one by packing into below the cover plate, fill and lead up slit all around, fuselage edge with argon arc welding again, use the polishing machine sanding and polishing.The integral body of the range hood through being processed into like this is more solid more attractive in appearance than original fuselage, the also faster convenience of maintenance washes.And since the fuselage front of this range hood and the frame of the right and left lean outward, so its exhaust fume collecting hood top section ratio lower section is little, flow velocity top when therefore oil smoke is sucked is bigger than the bottom, has promptly enlarged markedly the range hood that disposes this fuselage extracting force to oil smoke.

The technical scheme of the utility model range hood three limit flare fenestration integral bodies is: it comprise have breach 1 and all around folding the cover plate A of frame 2 is arranged; Than cover plate A appearance and size smaller comprise base plate 4, boss 5, hole, center 6, all around folding has the exhaust fume collecting hood B of 7 grades that turn edge; The place ahead that it is characterized in that the breach 1 of cover plate A has the window 3 of band window lid, and all around the frame of the front of frame 2 and the right and left has camber angle Φ≤70 °; The camber angle Φ that the front of exhaust fume collecting hood B and the right and left turn edge ₁Equate with the camber angle Φ of cover plate A frame.Then exhaust fume collecting hood B is become one by packing into below the cover plate A, fill and lead up slit all around, fuselage edge with argon arc welding again, use the polishing machine sanding and polishing.Make it to become the utility model range hood three limit flare fenestration integral bodies.Because this product is to shape the back socket respectively by two blocks of whole stainless steels, again through welding, sanding and polishing, be the integral body that a kind of nothing connects the scar weld seam therefore, sump oil does not have the hiding-place; Because preceding, the left and right side frame of this fuselage lean outward, so its exhaust fume collecting hood B top section ratio lower section is little, the flow velocity top when oil smoke is sucked is bigger than the bottom, therefore enlarged markedly the extracting force of range hood again to oil smoke.

Four, description of drawings

Fig. 1 is the utility model range hood three limit flare fenestration integral body decomposition chart and views thereof.

Fig. 2 is the utility model range hood three limit flare fenestration integral body outline drawings.

Among the figure: A, cover plate; 1, breach; 2, frame; 3, window; B, exhaust fume collecting hood; 4, base plate; 5, boss; 6, hole, center; 7, turn edge; Φ, Φ ₁, camber angle.

Fig. 1, Fig. 2 illustrate:

The utility model range hood three limit flare window-opening integral frame of oil-smokes are an overall structure, and it is not by monoblock The exhaust fume collecting hood B that the cover plate A that the rust steel plate punched forms and monoblock corrosion resistant plate are stamped to form forms; At cover plate A On be processed with breach 1, frame 2, the camber angle Φ of front and the right and left≤70 ° wherein are with the window lid Window 3; Be processed with base plate 4 on the exhaust fume collecting hood B, boss 5, hole, center 6 turns edge 7, wherein the front and The camber angle Φ of the right and left₁Equate (seeing view) with the front of cover plate A and the frame camber angle Φ of the right and left.

Five, the specific embodiment:

At first, on punch press, stamp out breach 1, window 3 (being with window lid) and frame 2 then, and make wherein the front and the frame camber angle Φ of the right and left≤70 ° according to the development size of cover plate A monoblock stainless steel plate under shearing on the plate shearing machine; According to development size monoblock stainless steel plate under shearing on the plate shearing machine of exhaust fume collecting hood B, on hydraulic press, suppress boss 5 then, after cutting edge, on punch press, go out the hole, center 6 of boss 5 again and turn edge 7, and the camber angle Φ that front and the right and left are turned edge ₁Equate with the camber angle Φ of frame 2.Again exhaust fume collecting hood B is packed into by cover plate A below and become one,, promptly become main part the utility model range hood three limit flare fenestration integral bodies of range hood after welding, polishing, polishing.
