Abstract
The utility model relates to a kitchen ventilator three-way air intake oil collecting tray. The structure of the utility model comprises a prismoid-shaped integral seamless frame, wherein the bottom surface (1) of the utility model is a flat surface with no apertures; the left, the right and the front wall surfaces (2) are all provided with air inlet holes (3) except for the rear wall surface (4) of the wall surfaces of four peripheries of the frame. As the direction of the air inlet hole of the oil collecting tray well fits the actual trend of oil smoke; thus the air inlet resistance is small; thereby, the strength of a kitchen ventilator sucking the oil smoke is improved. At the same time, because the oil collecting tray is not provided with air inlet holes in the vertical direction and the rear wall surface (4), the possibility of dirty oil dropping into cooking pots from air inlet apertures can be avoided, and the stain of the oil smoke to the kitchen wall surfaces can be reduced.
Description
One, technical field
The utility model relates to a kind of draw-off tray of range hood, the tripartite air intake draw-off tray of specifically a kind of range hood.
Two, background technology
Know that all the draw-off tray of one of strength member of range hood mainly contains the effect of following two aspects for the people that produce and make range hood: the oil that range hood is separated from soot gas is assembled to be allowed it flow in the lubricating cup of storage to go; Secondly, absorb the air intake passage of oil smoke as range hood; For the latter, find that after deliberation it directly affects the suction of the suction oil smoke of range hood, about promptly the operating efficiency of range hood.According to our nearest investigation, at present also there is following defective in the draw-off tray produced of the manufacturer of each lampblack absorber: the distribution of fresh air inlet all is confined on vertically downward the direction on the draw-off tray, in fact strict, one, this perforate direction is not to match from the actual condition that the pot and stove periphery produces with oil smoke, so the air intake resistance is bigger; Its two since draw-off tray on fresh air inlet direction vertically downward, be difficult to avoid sump oil from fresh air inlet, to splash in the pot; Its three, for the occasion that the slit is installed is arranged between range hood rear wall and the kitchen range wall, when range hood work, from then on the part oil smoke ran away in the slit, day long month of a specified duration, bright and clean kitchen metope has been subjected to stained.
Three, summary of the invention
The technical scheme of the utility model technical issues that need to address and proposition is: a kind of air intake resistance that reduces oil smoke is provided, thereby increase the suction force of range hood, utterly destroy sump oil simultaneously from whenever splashing into pot phenomenon of internal contamination dish and reducing the tripartite air intake draw-off tray of a kind of range hood that the kitchen metope is tarnished to oil smoke.
Its structure of the tripartite air intake draw-off tray of the utility model range hood comprises a terrace with edge shape integral seamless framework, it is characterized in that bottom surface (1) is the plane, on the wall around the framework, except that rear surface (4), other are left and right, all be shaped on fresh air inlet (3) on the place ahead wall (2).Because no fresh air inlet is gone up in the bottom surface (1) of this draw-off tray, and fresh air inlet (3) is arranged on other tripartite wall (2), therefore, this perforate direction matches with the actual trend of round oil smoke that rises from pot and stove periphery generation back, so the air intake resistance is less; Simultaneously because the vertical direction on the draw-off tray does not have fresh air inlet, therefore avoided sump oil from fresh air inlet, to splash into a possibility in the pot fully, guaranteed that the salubrious dish of user avoids polluting; Secondly, because framework rear surface (4) is gone up no fresh air inlet, therefore when range hood when aspirating oil smoke, the air pressure at rear is higher than other tripartite air pressure (flow velocity was big when left and right, preceding tripartite oil smoke was inhaled, pressure is low), thereby the oil smoke that part is run away through the installation slit at the lampblack absorber back side has played the effect of resistance ease, has reduced oil smoke stained to the kitchen metope.
Four, description of drawings
Fig. 1 is the structural representation of the tripartite air intake draw-off tray of the utility model range hood:
Among the figure: 1, bottom surface; 2, wall; 3, fresh air inlet; 4, rear surface.
The specific embodiment:
Below in conjunction with Fig. 1 the specific embodiment of the present utility model is further described:
Realize that the tripartite air intake draw-off tray of the utility model range hood can be with following two kinds of methods:
1. be the method for material with sheet metal: shape and the size of at first having calculated metal blank according to the shape of the tripartite air intake draw-off tray of range hood with punching press, integral seamless drawing and forming in shaping mould, go out fresh air inlet 3 left and right, the preceding three parts of molding framework then, promptly become the tripartite air intake draw-off tray of the utility model range hood.
2. with metal or the integrated poured method of nonmetallic materials: at first carry out and water injection molding according to the shape of the tripartite air intake draw-off tray of range hood, then the metal that melts or nonmetallic materials are poured into a mould and into water in the injection molding, treat that opening mould after its cooling promptly becomes the tripartite air intake draw-off tray of the utility model range hood.
Claims (1)
1, the tripartite air intake draw-off tray of a kind of range hood, the bottom surface (1) that it is characterized in that a terrace with edge shape integral seamless framework is the plane, all is shaped on fresh air inlet (3) on left and right, the place ahead wall (2) of framework.
