Abstract
The utility model relates to a fume exhauster with an external oil collector. The fume exhauster with an external oil collector comprises a machine casing (1) and a blower (2). The blower (2) is positioned on the upper part of the machine casing (1) and is sealed by a partition plate (3) with an air inlet (4). A concave oil collecting device (9) is arranged below the air inlet (4). A certain distance is arranged between the concave oil collecting device (9) and the partition plate (3). The air inlet (4) is supported by the upward opening of the concave oil collecting device (9). A gap is arranged between the air inlet (4) and the upward opening. Once residual oil is accumulated in a machine casing, the oil can drip into the concave oil collecting device (9) and an oil collecting cup along a volute of the blower or the inner side wall of the partition plate through the air inlet. Thereby, oil drops can no longer drip outwards. In addition, noise can be effectively reduced through the unique structure of the oil collecting device and the centrifugal type blower.
Description
The utility model relates to a kind of culinary range hood, particularly a kind of external oil collector type fume exhaust fan.
Existing range hood roughly is divided into slim and dark type two big classes, and slim general employing axial flow blower is horizontally set on the casing top, and its air inlet down; Dark type generally adopts centrifugal blower, is vertically set on top, casing rear portion, and its air inlet forward; The former advantage is that manufacturing cost is lower, and shortcoming is that suction is strong inadequately, and because air inlet is arranged on the top, machine inner product oil more or less can get off from the air inlet water clock; And the latter is just in time opposite, suction by force, not easy oil leakage but cost height; For the former, there has been improved structure to emerge at leakage of oil, promptly the guard central authorities at air inlet are provided with a catchment cup, this has solved the problem of part leakage of oil, but still can enclose long-pending oil on the guard, long oil leakage phenomenon of time one is still inevitable, and has the air inlet of greasy dirt and guard thereof and also influence attractive in appearancely, and the design of this catchment cup simultaneously also can make range hood produce bigger noise when work.
The purpose of this utility model is with regard to being at the present situation of above-mentioned prior art and provide a kind of cost relatively low and can effectively stop the external oil collector type fume exhaust fan of described oil leakage phenomenon.
The purpose of this utility model is achieved in that external oil collector type fume exhaust fan comprises casing and blower fan, blower fan is positioned at casing top, and seal by a dividing plate of bringing the air port into, it is characterized in that under described air inlet, being provided with one with dividing plate spill oil catcher at regular intervals, its up uncovered catches air inlet and leaves the gap with it; For removing oil dripping easily, also can open an osculum, and a dismountable catchment cup is set under it in the oil catcher bottom; Described blower fan is good to adopt centrifugal fan.
Compared with prior art, in case casing inner accumulated of the present utility model has Residual oil, they will splash in oil catcher and the catchment cup through air inlet along volute of blower or dividing plate madial wall, the oil smoke that does not enter simultaneously air inlet also will enter in the oil catcher through the gap of air inlet and oil catcher along the lateral wall of dividing plate, thereby oil droplet will can outwards not drip again, and the noise of the employing of unique oil catcher structure and centrifugal fan also can reduce range hood work effectively the time.
Description of drawings:
Fig. 1 is the structure cross-sectional schematic (clear for making drawing, as to omit each wall thickness hatching) of the utility model embodiment.
Fig. 2 is the upward view of Fig. 1.
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As Fig. 1, shown in Figure 2, external oil collector type fume exhaust fan comprises casing (1) and blower fan (2), blower fan (2) is positioned at casing (1) top, and seal by a dividing plate (3) of bringing air port (4) into, blower fan in accompanying drawing embodiment (2) adopts centrifugal fan, by motor (5) and impeller (6) and spiral case (7) formation thereof, under described air inlet (4), be provided with one with dividing plate (3) spill oil catcher at regular intervals (9), its uncovered air inlet (4) that catches fully up also leaves the gap with it, and oil catcher in accompanying drawing embodiment (9) is hung under the dividing plate (3) by connecting support (8); Said structure can be realized goal of the invention of the present utility model, but for the convenience of the user, a better design is to open an osculum in described oil catcher (9) bottom, and a dismountable catchment cup (10) is set under it, with the collected oil dripping of convenient removing.
Blower fan (2) also can adopt other types in above-mentioned, and being connected between oil catcher (9) and the dividing plate (3) can also be other various schemes, and their structural change all within design of the present utility model, does not exceed protection domain of the present utility model.
Claims (5)
1. external oil collector type fume exhaust fan, comprise casing (1) and blower fan (2), blower fan (2) is positioned at casing (1) top, and seal by a dividing plate (3) of bringing air port (4) into, it is characterized in that under described air inlet (4), being provided with one with dividing plate (3) spill oil catcher at regular intervals (9), its up uncovered catches air inlet (4) and leaves the gap with it.
2. external oil collector type fume exhaust fan as claimed in claim 1 is characterized in that described blower fan (2) is a centrifugal fan, by motor (5) and impeller (6) and spiral case (7) formation thereof.
