The oil collecting structure is characterized in that a groove is formed in the middle of the front end of the gas collecting hood, the bottom of the groove is provided with oil-dripping holes, the lower end of the back of the gas collecting hood is provided with a smooth arc flow guiding surface for catching the oil droplets from the oil-dripping holes, and the oil collecting cup is arranged below of the flow guiding surface for receiving oil blots from the flow guiding surface. Compared with the prior art, the invention has advantages that the accumulated oil blots enter the flow guiding surface from the oil-dripping holes, and then flow into the oil collecting cup, the flow guiding surface integrated with the gas collecting hood is used for collecting oil, the integral design is simple, reasonable and effective without the match of extra hosepipes, so that an oil collecting system is not blocked.
Description
Technical field
The present invention relates to a kind of lampblack absorber, relate in particular to a kind of oil collecting structure of range hood.
Background technology
Common lampblack absorber all is equipped with catchment cup basically, and usually catchment cup all is arranged on the exhaust fume collecting hood bottom dismountable type, during cleaning, catchment cup is disassembled, and loads onto again after cleaning finishes.
The patent documentation of a lot of lampblack absorber catchment cups is also disclosed in the prior art, as the patent No. is Chinese utility model patent " the dark kitchen hood of inclined type the blower fan " (Granted publication number: CN2290788Y) of ZL96205439.9, this patent imports to the oil in attached stream plate and the blower fan in the oil trap by flexible pipe respectively, can also referenced patent number is Chinese utility model patent " a kind of dark range hood " (Granted publication number: CN2260974Y) of ZL96202373.6.Similarly can also be with reference to Chinese patent literature CN2658619Y, CN2596238Y or the like.
Though above-mentioned prior art structural design is comparatively compact, and the greasy dirt processing is convenient, remains the place in shortcoming: at first, adopt flexible pipe to come water conservancy diversion, greasy dirt stops up flexible pipe easily, thereby causes that Oil Guide is not smooth; Secondly, flexible pipe needs arrangement space and built-up time, thereby causes design succinct inadequately, assembles comparatively loaded down with trivial details; Secondly, existing oil collecting structure can only be collected the greasy dirt of blower fan inboard usually, and cannot collection and treatment for the greasy dirt in the blower fan outside.
Summary of the invention
First technical problem to be solved by this invention is to provide a kind of greasy dirt water conservancy diversion smooth and easy oil collecting structure of range hood efficiently at the above-mentioned state of the art.
Second technical problem to be solved by this invention provides the slap-up oil smoke oil collecting structure of a kind of oil-collecting.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of oil collecting structure of range hood, comprise exhaust fume collecting hood and be located at the catchment cup of exhaust fume collecting hood bottom, it is characterized in that described exhaust fume collecting hood front end face middle part forms groove, this bottom portion of groove offers oil dripping hole, lower end, the described exhaust fume collecting hood back side has the guide face of smooth arc, this guide face is accepted the oil droplet that aforementioned oil dripping hole flows down, and described catchment cup then is located at aforementioned guide face below and is accepted the greasy dirt that flows down from guide face.
Described guide face at interval be provided with two leakproof oil glutens, described catchment cup upper port is then between aforesaid two leakproof oil glutens.Leakproof oil gluten can guarantee that greasy dirt flows in the Oil Guide district of regulation, and can arbitrarily not overflow.
Described guide face forms an oil trap perpendicular to described leakproof oil gluten, offers the outage that greasy dirt can be discharged into catchment cup in this oil trap.Oil droplet is flow in the catchment cup after oil trap accumulates to a certain degree together, the oil-collecting process is become in order rationally.
Described oil trap two ends offer the oil resistance hole that greasy dirt can be discharged into catchment cup respectively, and this aperture, oil resistance hole is greater than described outage aperture.It is the oil extraction pressure of alleviating outage that the oil resistance hole can be satisfied when greasy dirt is more, to amplify oil extraction efficient.
The syndeton of catchment cup and exhaust fume collecting hood is preferably as follows design: described guide face is positioned at the outside, two described oil resistance holes and offers installing hole respectively, and accordingly, described catchment cup upper port both sides have the hook portion that is suitable for being hooked in aforementioned installing hole respectively.
Described exhaust fume collecting hood front end face is provided with a cowling panel over against air inlet, and this cowling panel and described exhaust fume collecting hood maintain the spacing that predetermined fuel feeding cigarette passes through, and described oil dripping hole is accepted the greasy dirt that flows down from described cowling panel medial surface.Can satisfy the requirement of accumulation cowling panel medial surface greasy dirt.
Described groove middle part is an air inlet, is provided with a spiral case blower fan in this air inlet, and, and described guide face is accepted the greasy dirt that this spiral case blower fan outside flows down, and can satisfy the requirement that the accumulation spiral case blower fan outside flows down greasy dirt.
Compared with prior art, the invention has the advantages that: the greasy dirt of accumulation enters guide face from oil dripping hole, flow in the catchment cup then, adopt and the auxiliary oil-collecting of the integrated guide face of exhaust fume collecting hood, the global design advantages of simple is effective, it is supporting to need not extra flexible pipe, the situation that does not exist oil collecting system to stop up.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2 and shown in Figure 3, lampblack absorber oil-collecting in the present embodiment comprises exhaust fume collecting hood 1, is located at the catchment cup 3 of exhaust fume collecting hood 1 bottom, cowling panel 2 and spiral case blower fan 5, cowling panel 2 is provided with over against air inlet 11 at exhaust fume collecting hood 1 front end face, and maintaining the spacing that predetermined fuel feeding cigarette passes through with exhaust fume collecting hood 1, spiral case blower fan 5 is located at air inlet 11 positions of exhaust fume collecting hood.
As shown in Figure 2, exhaust fume collecting hood 1 front end face middle part forms groove 12, these groove 12 bottoms offer oil dripping hole 13 (again visible accompanying drawing 5), and air inlet 11 is positioned at groove 12 central authorities, and oil dripping hole 13 is accepted near the greasy dirt that is positioned in greasy dirt that self-rectifying plate 2 medial surfaces flow down and the groove 12 air inlet 11.Lower end, exhaust fume collecting hood 1 back side has the guide face 8 of smooth arc, and this guide face 8 is accepted the oil droplet that oil dripping hole 13 flows down, and 3 of catchment cups are located at guide face 8 belows and are accepted the greasy dirt that flows down from guide face 8 and the greasy dirt in spiral case blower fan 5 rearward end and the outside.
