Abstract

The utility model relates to a domestic device for sucking and exhausting oil smoke, which comprises a casing of an air exhausting mechanism, a motor, impellers, an air duct and an air suction guard, wherein the air exhausting mechanism is arranged on a wall opening onto the outside world, the casing as a part of the air duct is connected with the air outlet end of the air duct and the installation of the casing causes a lower included angle between an impeller shaft and a wall surface to be an acute angle. The air suction guard is arranged above an oil smoke source and is connected with the air inlet end of the air duct, and an oil gathering trough and an oil gathering cup are arranged in the suction guard. The utility model has the advantages of high efficiency of oil smoke suction and exhaustion, low noise and effective oil gathering.

Description

hood

The utility model relates to a kind of compound ventilation air-changing device, the fume exhaust device that particularly a kind of family kitchen is used.

The fume exhaust device that two kinds of forms are arranged at present.A kind of is ventilation fan, and it is made up of blast fan and motor, is contained in to lead on the extraneous wall or window, and impeller shaft is perpendicular to wall, and its action principle is to allow oil smoke loose in kitchen space earlier, with the mode of exhausting the air in the kitchen is all changed then.Though ventilation fan is simple and practical, because oil smoke diffusion formerly, causes the greasy dirt deposition is arranged inevitably on indoor wall and the utensil, and still do not have effective oil collector sump tank at present, cause that greasy dirt disorderly drips under the ventilation fan.Another kind is a range hood, it is by motor, impeller, the spiral case air channel is formed, be contained in top, oil smoke source (cooking stove), directly introduce the oil smoke that cooking stove produces outdoor, because air inlet directly links to each other with spiral case, electric motor with vane wheel is contained in the spiral case, the air-flow that forms from the rotary blade spiral case that at first will clash into and rub, to turn 90 ° the curved air channel that enters then, influenced the exhaust air rate of device, not only energy loss is big, efficient is low, and noise is big, require the indoor air stream momentum little during use, the Aisle type kitchen is inapplicable, even will close the door when using, close window, also have, meeting oil dripping in this device inlet scoop easily makes the operating personnel meet and discuss.

The purpose of this utility model is, overcomes existing ventilation fan and range hood shortcoming separately, proposes a kind of fume exhaust high efficiency, power consumption family expenses fume exhaust device little, effectively oil-collecting.

Technical solution of the present utility model be with ventilation fan as air draft mechanism, new fume exhaust device is formed in it and suspended hood, air channel together, and in suspended hood the effective oil collector sump tank of design.Specifically, composition of the present utility model comprises casing, motor, the impeller of air draft mechanism, the air channel, it is characterized in that: the casing of (1) air draft mechanism connects the air channel outlet air end as the part in air channel, casing is installed in and leads on the extraneous wall, and its installation makes that angle α is an acute angle under impeller shaft and the metope, suspended hood of (2) air channel air intake connection, this suspended hood is installed in top, oil smoke source, and the oil collector sump tank of being made up of oil trap and catchment cup is housed in the cover.

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.

Fig. 1 is the utility model overall structure scheme of installation.

Fig. 2 is the utility model embodiment 1 oil collector sump tank front schematic view.

Fig. 3 is the A-A schematic diagram of Fig. 2.

Fig. 4 is the utility model embodiment 2 front schematic view.

Fig. 5 is the A-A schematic diagram of Fig. 4.

As shown in Figure 1, composition of the present utility model comprises casing 2, impeller 8, the motor 7 of air draft mechanism, air channel 6, and the casing of air draft mechanism is as the part in air channel 6, connect the air channel outlet air end, casing is installed in and leads on the extraneous wall 5, and its installation makes that angle α is acute angle under impeller shaft 1 and the metope, and air channel 6 air intakes connect a suspended hood 3, this suspended hood is installed in cooking stove 4 tops, oil smoke source, oil collector sump tank is housed in the cover, and not expression among Fig. 1 is referring to Fig. 2, Fig. 3, Fig. 4 and Fig. 5. The utlity model has two obvious effects, the one, the air-flow angle of turning round in the air channel is little, and the air suction efficiency height is low in energy consumption, noise is low, and the 2nd, be adsorbed on greasy dirt on the impeller and can not drip everywhere and drop down, but in flowing into oil collector sump tank in the suspended hood along the air channel. Among the embodiment suspended hood 3 be one up, the cover body of rear and left and right sides sealing, positive the place ahead is not sealed, be installed on the oil smoke source cooking stove 4 back upper place walls 5, this moment, the cover body rear portion was served as by wall, cover body top is rectangle, the cover body both sides are right angled triangle, and such suspended hood can make oil smoke just needless to say spread and in time enter suspended hood, does not hinder again kitchen's operation.

Oil collector sump tank in the utility model suspended hood has two kinds of technical schemes, illustrates by two embodiment.

Embodiment 1 oil collector sump tank as shown in Figures 2 and 3, installation one and cover body top spill oil trap 10 in the same way in suspended hood 3 and below 6 junctions, air channel, the oil trap width is less than the cover body upper width, so oil trap and cover body top constitute the air inlet 9 of suspended hood, oil trap be located at oil smoke must through road below, effectively oil-collecting does not make greasy dirt disorderly drip.The oil trap lowest part has oil outlet 12, and catchment cup 11 is housed under the hole, and catchment cup can be connected with oil trap by screw or hook, is convenient to take off catchment cup and falls oily.

Embodiment 2 oil collector sump tanks as shown in Figure 4 and Figure 5, suspended hood 3 is connected by a horn mouth 13 with air channel 6, annular oil trap 10 is installed in the horn mouth lower end, trench bottom is to lopsidedness, lowest part at groove has oil outlet 12, catchment cup 11 is housed under the hole, and catchment cup can be connected with oil trap with screw or hook, is convenient to take off catchment cup and falls oily.
