Description

The water washing cleaning fume exhaust cover

The utility model relates to a kind of fume exhaust cover.

At present, common oil extraction cover system is located at the stove and accessory top, the hot gas of being given birth to when utilizing the cover body circle to cover the stove and accessory culinary art, and borrow the extraction fan that connects on the fume exhaust cover, hot gas is discharged, reduce the hot gas in the kitchen, yet the hot gas in the kitchen usually contains the grease of a large amount of vaporizations, cause air pollution, so all be provided with filter on many fume exhaust cover,, then remove the collected grease of filter again to reduce the fat content of its hot gas of being discharged.

Yet, viscosity because of grease itself, when getting rid of and clean the collected grease of oil extraction cover, need unload filter earlier, re-use a large amount of cleaning agents and clean repeatedly, not only extremely inconvenient, and cause another kind of the pollution, and the grease that filter is accumulated is also because of the hot environment in kitchen, and often initiation fire endangers public security.

In view of this, the purpose of this utility model provides a kind of water washing cleaning fume exhaust cover, borrows the non-oil soluble liquid of seasoning in the oil trap, mix with the hot gas that contains grease the vaporization back, borrow the non-oil soluble liquid in the oil trap again, make grease floating thereon, so that utilize overflow pipe that it is discharged.

The purpose of this utility model is achieved in that a kind of water washing cleaning fume exhaust cover, it is characterized in that: it mainly comprises air chamber, fume exhaust cover, oil trap and overflow pipe, wherein air chamber is the space of a sealing, this air chamber is provided with an air inlet and a gas outlet, form by several pieces aeroscopic plates in this air chamber again, lowest part one ora terminalis of this aeroscopic plate and the wallboard of air chamber separately, aeroscopic plate is the Z-shaped space that is divided into continuous bend in the air chamber again; Fume exhaust cover is to be installed in the air inlet top of air chamber and the hollow cover body of lower opening; Oil trap is arranged on the air inlet place, and overflow pipe is applied in the oil trap bottom, and this overflow pipe one opening is positioned at the oil-collecting slot part, and another opening is positioned at the fume exhaust cover outside.

Above-mentioned air chamber closes on the stove and accessory side and is provided with an outside plate, forms a flat enclosure space between this outside plate and air chamber, and this enclosure space is provided with two openings, and the one opening is positioned at the air inlet place, and another opening is positioned at the top of fume exhaust cover; Be provided with a throttling ball float in the above-mentioned oil trap.

Owing to adopt such scheme: be convenient to get rid of the grease in the hot gas, exempt the trouble of cleaning fume exhaust cover.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments stereo appearance figure.

Fig. 2 the utility model exemplary embodiments is broken and schematic diagram.

Fig. 3 the utility model exemplary embodiments generalized section.

Fig. 4 the utility model exemplary embodiments action schematic diagram.

The figure number explanation of main element:

Fume exhaust cover 1, air chamber 2, air inlet 3, gas outlet 4, aeroscopic plate 5, oil trap 6, throttling ball float 7, cooling water 8, outside plate 9, overflow pipe 10.

Present embodiment comprises an air chamber 2, and this air chamber 2 is the space of a sealing, and this air chamber 2 also is provided with the gas outlet 4 that an air inlet 3 and is connected to the extraction fan (not shown); One oil trap 6, this oil trap 6 is to be located at air inlet 3 places, wherein seasoning has non-oil-soluble cooling water 8, and the housing of the cooling water 8 of institute's seasoning and fume exhaust cover 1 is at air inlet 3 places, and keep a minim gap, the hot gas that fume exhaust cover 1 is extracted can be with cooling water 8 vaporizations at this place, as shown in Figure 1, 2.

Also comprise a slice aeroscopic plate 5 (as shown in Figure 3) at least in the air chamber 2, an ora terminalis of this aeroscopic plate 5 is not connected with the wallboard of air chamber, and this ora terminalis system is complete in the lowest part of aeroscopic plate 5, and this aeroscopic plate 5 also will be divided into the Z-shaped space of continuous bend in the air chamber 2.

In addition, air chamber 2 closes on the stove and accessory side and is provided with

outside plate

9, and 2 of this outside plate 9 and air chambers form a flat enclosure space, and this enclosure space also is provided with two openings, and the one opening is positioned at air inlet 3 places, and another opening is arranged in the top of fume exhaust cover cover body.

Be provided with a throttling ball float 7 and an overflow pipe 10 in the oil trap 6, this throttling ball float 7 is the liquid level in order to control cooling water 8, and overflow pipe 10 is in order to discharge grease, when the liquid level of cooling water 8 is crossed when low, this throttling ball float 7 cooling water 8 that will reinject, so that its liquid level reaches overflow pipe 10 mouths of pipe, make the grease that floats over cooling water 8 surfaces flow out oil trap by this mouth of pipe.

The course of action of present embodiment is as follows: (as shown in Figure 4):

When being connected the extraction fan (not shown) running at 4 places, air chamber 2 gas outlets, the air of air chamber 2 inside will be discharged from via gas outlet 4, the air of air chamber 2 inside will flow to 4 places, gas outlet this moment, the air at air chamber 2 air inlets 3 places then is attracted in the air chamber 2, because of the cooling water 8 and the housing of fume exhaust cover 1 are only kept a minim gap at air inlet 3 places, when air is flowed through minim gap, to cause the air pressure of these place's cooling water 8 liquid levels to reduce because of the white law of making great efforts, the vaporization phenomenon that causes this place's cooling water 8, and the cooling water 8 of vaporization will suck the hot gas contain grease with air inlet 3 places and mix, the cooling water 8 of this vaporization will make the grease condensation and liquefy in air chamber 2, the grease of liquefaction will inwall and aeroscopic plate 5 attached to air chamber 2 on, and drip and drop down onto down the liquid level of cooling water 8 at last, discharge via overflow pipe 10 again.

The utility model only just can be removed the collected grease of fume exhaust cover with clear water, exempting located by prior art need meet environmental protection requirement by the puzzlement of a large amount of cleaning agent repeated washing, and floats over the liquid level of cooling water because of grease system, the tongues of fire can't directly touch grease, so can avoid the generation of fire.
