Description
Technical field
A kind of range hood is the utility model is related to, belongs to technical field of kitchen wares.
Background technology
Range hood is the widely used electric equipment in kitchen, for discharging caused oil in cooking stove cooking process
Cigarette.Before oil smoke is discharged to flue, grease separation is carried out by the filter screen set in range hood, to avoid oil-containing gases straight
Run in and polluted into air.Existing mechanical filter screen increases collision probability mainly by increase and oil smoke contact area
Carry out separating and filtering oil smoke, but bring resistance to increase rapidly therewith, the unfavorable result that air quantity reduces.
In order to strengthen the filter effect of range hood, oneself has some improved plans at present, and one of which scheme is profit
With high surface area ratio lathery and liquid soap for the readily soluble performance of grease, using frothing, machine enters fume-exhausting in oil smoke
A large amount of bubbles, increase and the contact area of oil smoke are blown out during machine exhaust fume collecting hood, to lift fume-exhausting oil filter effect.
With reference to the Patent No. ZL201420511601.4 of the applicant Chinese utility model patent《A kind of oil strain formula is inhaled
Lampblack absorber》(Authorization Notice No. CN204141661U), the patent include exhaust fume collecting hood, filter screen and on exhaust fume collecting hood simultaneously
Cowling panel below filter screen, the air intake region between cowling panel and filter screen are provided with foam maker, and foam maker is extremely
Rare two, and be distributed in around air intake region.But this range hood, caused soap bubble amount is smaller, and is distributed not
Uniformly, filter effect is not very good；Independent motor driving in addition, designing wiring is complicated, and cost is higher.
The applicant discloses a kind of range hood of improved foamed filter again, sees Patent No.
ZL201520627448.6 Chinese utility model patent《A kind of range hood for strengthening filtering》(Authorization Notice No. is
CN204987156U), bubbler is provided between the filtering screen and filter screen, the bubbler is in the filtering screen
Extension on length direction.The covered incoming air area very little of this design, it is limited to the filter effect of oil smoke.The rotation of bubbler
Turn to need to overcome the resistance of other frothed liquids such as liquid soap, under the gears such as weak wind-force, realized with air intake rotation relatively difficult.
Limited by installation site space, its foam number can not be very big, and degree filtering oil smoke effect is limited.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bubble big oil smoke for the above-mentioned state of the art
The good foam of interception result intercepts filtering range hood.
Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of foam intercepts filtering fume-exhausting
Machine, including case, blower fan and exhaust fume collecting hood, for foregoing blower fan in case, foregoing exhaust fume collecting hood is located at the air intake of case lower end

One direction rotates, and foregoing the first indulges in serfing the Net part in the feed flow port of foregoing liquid storage box；And
Second revolving part, the air inlet of in aforementioned brackets and face case lower end can be rotatably located at, second rotation
Turn second impeller and outer ring of the part including inner ring second indulges in serfing the Net, and the second foregoing impeller can edge in the presence of wind-force is risen
One direction rotates, also, the direction of rotation of the direction of rotation of the second foregoing impeller and the first impeller is on the contrary, foregoing second
Foaming mesh portions are located in the feed flow port of foregoing liquid storage box, and the foregoing second foaming screen cloth is placed in the first and indulges in serfing the Net top simultaneously
Gap be present between being indulged in serfing the Net with the first.
Further, the bottom surface of the liquid storage box is an inclined plane, accordingly, the surfaces of revolution of first revolving part with it is foregoing
Inclined plane general parallel orientation.
The air inlet of the case lower end is provided with the filter screen of back taper, and the bottom of the filter screen is provided with lubricating cup, described foam
Generator is located between filter screen and blower fan.After the part oil droplet that foam maker intercepts drops onto filter screen, entered along filter screen
In lubricating cup.
Further, the first described impeller includes the first connecting pole and set around the first connecting pole at least three first
Axial flow fan leaf, the first described connecting pole rotatably can be connected on support.
Further, the second described impeller includes the second connecting pole and set around the second connecting pole at least three second
Axial flow fan leaf, the second described connecting pole rotatably can be connected on support.
Further, described liquid storage box is on the rear end of support.
Preferably, described the first revolving part and the second revolving part Plane of rotation general parallel orientation.
Compared with prior art, the utility model has the advantage of：Because the first revolving part and the second revolving part face enter
Air port is set, therefore covering incoming air area is big, and bubbles volume produces more, the evolution good filtration effect to oil smoke, blower fan work, air-flow
Rising, the first revolving part and the second revolving part can rotate freely along a direction, be driven without separate power, and design is simple,
Installation cost is low, and the first, which is indulged in serfing the Net, need not overcome the resistance of bubble water mixed liquid, lampblack absorber wind when indulging in serfing the Net and rotate with second
Power gear hour can also keep rotary speed quickly to ensure bubble yield；Further, since the first impeller and the second leaf
On the contrary, the first is indulged in serfing the Net, the liquid film online with the second foaming is constantly widened in rotary course for wheel direction of rotation, in air intake wind
In the presence of power, very big bubble is formed, there is sufficiently large surface area, contaminant particle in interception oil smoke, bubble can be adsorbed
Mix and be inhaled into blower fan with oil smoke, strengthen the mobility of greasy dirt, residual of the less greasy dirt on impeller spiral case is viscous, improves oil
The grease separating degree index of cigarette machine.
