Abstract

The utility model relates to a double-edge external-inclined integrated fume collecting hood which is one of main parts of a fume exhauster and is an integrated fume-exhauster fume collecting hood formed on an integrated stainless steel plate through punching. The utility model comprises a bottom plate (1), a dummy club (2), a central hole (3), a lamp hole (4), a frame (5), etc. Because the external-inclined angle phi of both side edges of the frame (5) from top to bottom is equal to 3-45DEG, the section of the upper part of the double-edge external-inclined integrated fume collecting hood is smaller than that of the lower part. When the fume exhauster provided with the fume collecting hood works, the flow speed of fumes of the upper part is larger than that of the lower part when the fumes is sucked so that the utility model has an ideal sucking effect and is a fume-exhauster fume collecting hood having the advantages of cleanness, firmness and high fume sucking force without increasing cost.

Description

The whole exhaust fume collecting hood of bilateral external inclined type

One, technical field

The utility model relates to a kind of housing on the kitchen hood, specifically the whole exhaust fume collecting hood of the bilateral external inclined type of range hood.

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 do not connect the scar weld seam, but not very good for the rising oil smoke congregational rate that culinary art produces, it is not enough that cardinal symptom shows as extracting force.

Three, summary of the invention

The purpose of this utility model provides a kind of range hood connects the scar weld seam to the nothing of the extracting force of oil smoke whole exhaust fume collecting hood of bilateral external inclined type that increases.

The technical scheme of the whole exhaust fume collecting hood of the bilateral external inclined type of the utility model is: the whole exhaust fume collecting hood of the bilateral external inclined type of drawing on a monoblock corrosion resistant plate, its structure comprises base plate (1), boss (2), hole, center (3), lamp hole (4), frame (5) etc., boss (2) is in base plate (1) top, hole, center (3) is positioned at boss (1) middle part, two lamp holes (4) are arranged on the rear of base plate (1), it is characterized in that flare angle Φ=3～45 ° from top to bottom, frame (5) limit, the left and right sides, the last plane of frame (5) is shaped on step A (being connected with cover plate when being used for the range hood general assembly).Because the whole exhaust fume collecting hood of this bilateral external inclined type is that integral body shapes, nothing connects the scar weld seam, and sump oil does not have the hiding-place; Again because the limit, the left and right sides of this exhaust fume collecting hood frame (5) has flare 3～45 degree from top to bottom, so the top section ratio lower section of exhaust fume collecting hood is little, when the range hood work of this exhaust fume collecting hood is housed, flow velocity top when oil smoke is sucked is bigger than the bottom, and promptly top air pressure is significantly less than bottom air pressure, has increased pressure reduction, the suction effect of oil smoke is very good, so be a kind of cost that do not increase, firmly clean, the exhaust fume collecting hood of range hood of raising oil smoke suction force.

Four, description of drawings

Fig. 1 is the whole exhaust fume collecting hood construction profile of the bilateral external inclined type of the utility model figure.

Fig. 2 is the whole exhaust fume collecting hood orthographic drawing of the bilateral external inclined type of the utility model.

Among the figure: 1, base plate; 2, boss; 3, hole, center; 4, lamp hole; 5, frame; A, step.

Fig. 1, Fig. 2 illustrate:

The whole exhaust fume collecting hood of the bilateral external inclined type of the utility model is an overall structure, it above base plate 1 boss 2, boss 2 middle parts are shaped on hole, center 3, two lamp holes 4 are arranged on the rear of base plate 1, limit, frame 5 left and right sides is 3～45 ° of (see figure 2)s of flare from top to bottom, and the last plane of frame 5 is shaped on step A (being connected with cover plate when being used for the range hood general assembly).

Five, the specific embodiment:

Below in conjunction with Fig. 1 and Fig. 2 concrete enforcement of the present utility model is described further:

At first according to development size monoblock stainless steel plate under shearing on the plate shearing machine of the whole exhaust fume collecting hood of bilateral external inclined type, on hydraulic press, suppress boss (2) then, after cutting edge, on punch press, go out the vertical edge of hole, center (3), two lamp holes (4) and the frame (5) of boss (2) again, again this vertical edge is bent into frame (5) and step A on bender, and makes frame (5) left and right sides side 3～45 ° of flares from top to bottom.Through argon arc welding, polishing, polishing, promptly become the whole exhaust fume collecting hood of the bilateral external inclined type of the utility model again.Then, in the hole, center (3) of boss (2), load onto the cabinet of range hood, follow the last cover plate and fastening of placing of step A at the frame (5) of exhaust fume collecting hood, in hole, center (3) below and lamp hole (4), load onto parts such as draw-off tray, lubricating cup and illuminating lamp respectively at last, just become a complete novel range hood that the whole exhaust fume collecting hood of bilateral external inclined type is housed.

Claims

1, a kind of bilateral external inclined type integral body exhaust fume collecting hood of drawing on a monoblock corrosion resistant plate, its structure comprises base plate (1), boss (2), hole, center (3), lamp hole (4), frame (5); Boss (2) is in base plate (1) top, and hole, center (3) are positioned at boss (1) middle part, and two lamp holes (4) are arranged on the rear of base plate (1), it is characterized in that frame (5) dual-side flare angle Φ=3～45 ° from top to bottom;

2, the whole exhaust fume collecting hood of bilateral external inclined type as claimed in claim 1 is characterized in that the last plane of frame (5) is shaped on step (A).
