Abstract

The utility model of a new oil-absorbing smoke from the dumping triangular window of the overall set hood fuselage, oil-absorbing smoke is one of the main parts. It consists of stainless steel plate stamping block from the cover-hood A and B components. A Flat processed in a gap 1, 2 frame, the front and on both sides of the border, about phi <= 70 degree angle; processing on the B-hood a bottom 3, Boss 4, the center hole 5, and 2 frame angle equal 6 and up along the convex-4 wall before opening a window covered with a window 7; then set hood A B from the bottom plate into a set of integrated, the final welding, grinding, polishing from. This eliminates the fuselage from the original set hood, which are assembled with the cover around the edge of the fuselage cracks to make it more solid appearance, cleaning and maintenance more convenient; due to the fuselage of the three lateral borders outward dumping, so it The B-hood lower than the upper section cross section of small, it was fumes from the pump flow rate lower than the upper, which significantly increases the allocation of the fuselage on the fumes from the oil absorption smokemeters the pumping intensity.

Description

Range hood three limit flare exhaust fume collecting hood fenestration integral bodies

One, technical field

The utility model relates to a kind of fuselage of range hood, specifically range hood three limit flare exhaust fume collecting hood 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 exhaust fume collecting hood fenestration integral body technical issues that need to address and proposition is: remove the slit all around, fuselage edge of range hood, make complete machine more attractive in appearance, more firm, maintenance washes is also more convenient; And the increase range hood is to the extracting force of oil smoke.Specific embodiments is: get two corrosion resistant plates, and processing one breach on a corrosion resistant plate, all around folding has frame (back frame is shorter, and approximate turns edge), the cover plate that the frame of its front and the right and left leans outward; On another piece corrosion resistant plate, stamp out than cover plate appearance and size smaller comprise base plate, boss, the hole, center, four limits turn edge, and (an approximate frame afterwards turns edge, it can process with exhaust fume collecting hood integral body, also can load onto separately), the exhaust fume collecting hood that turns edge and equate of its front and the right and left with the frame flare angle of the front of cover plate and the right and left.On the place ahead at hole, exhaust fume collecting hood center, boss antetheca, open a window (have the window lid, can be convenient to maintenance) again to switch.Then exhaust fume collecting hood being packed into by the cover plate below becomes an integral body, fills and leads up slit all around, fuselage edge with argon arc welding again, uses the polishing machine sanding and polishing.The integral body of the range hood through being processed into has like this been eliminated the slit around the original fuselage edge, makes it more solid attractive in appearance, 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 exhaust fume collecting hood fenestration integral bodies is: it comprises and has the cover plate A that breach 1 and four edge breaks have frame 2, than cover plate A appearance and size smaller comprise base plate 3, the turn edge exhaust fume collecting hood B of 6 grades of boss 4,5, four limits, hole, center; It is characterized in that opening on the antetheca of the place ahead, boss 4 window 7 that has a window lid at the hole, center 5 of exhaust fume collecting hood B; The frame camber angle Ф of cover plate A front and the right and left≤70 °; The camber angle Ф that turns edge of the front of exhaust fume collecting hood B and the right and left ₁Equate with the front of cover plate A and the frame camber angle Ф of the right and left.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 exhaust fume collecting hood 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, therefore be a kind of appearance looks elegant, durable, clean range hood integral body easily; Again because three side frames of this fuselage lean outward, so its exhaust fume collecting hood B top section ratio lower section is little, so the flow velocity top of oil smoke when being sucked is bigger than the bottom, promptly enlarged markedly the range hood that disposes this fuselage extracting force to oil smoke.
