Description

A kind of smoke exhaust ventilator
Technical field
The utility model relates to a kind of catering industry equipment, is specifically related to a kind of smoke exhaust ventilator.
Background technology
Smoke exhaust ventilator is a kind of kitchen appliance that purifies kitchen environment.It is installed in kitchen health energy-saving range hood cooking stove top, the harmful oil smoke that produces in the refuse of cooking stove burning and the cooking process can be taken away rapidly, discharges outdoorly, reduces pollution, purifies air, and gas defence, explosion-proof safety guarantee effect are arranged.
Smoke exhaust ventilator has become Modern Family and the requisite cooking apparatus of catering industry.Early stage kitchen exhaust work is all finished by ventilating fan.Although ventilating fan can exclude the most of oil smoke in the kitchen, the oil smoke that it produces in the unable solution culinary art is to the pollution of whole kitchen and back room.The oil smoke that produces in the culinary art contains a lot of harmful materials, if the people works in being full of the room of oil smoke for a long time, can cause the generation of a lot of diseases.
The utility model content
The utility model purpose provides a kind of simple in structure, smoking is effective, noise is less smoke exhaust ventilator.
Scheme of the present utility model is as follows: a kind of smoke exhaust ventilator, comprise hood, centrifugal blower, and it is characterized in that described hood below is provided with the oblique mouth that advances, describedly enter the mouth place and be provided with oil filtering grid; Described centrifugal blower is positioned at the hood upper center, described centrifugal blower top or rear, hood middle part are provided with outlet flue, described centrifugal blower the right and left, below and the place ahead all seal and about two sides with below be provided with muffler plate, mouth is established back in described centrifugal blower the place ahead, and described time the mouth both sides are provided with at least two filtering oil smoke cylinders or cleaner; Described hood bottom and four limit peripheral frame are equipped with oil groove.
Described oil filtering grid is the cube that two layers of corrosion resistant plate form, described oil filtering grid two sides is equipped with the smoke intaking hole of equirotal vertical arrangement, described two sides smoke intaking hole is evenly staggered in vertical direction, and described oil filtering grid both sides are equipped with oil outlet.
Described cartridge filter is comprised of steel wire cylinder and macromolecular filtering cotton, and it is inboard that described macromolecular filtering cotton is centered around the steel wire cylinder, described steel wire cylinder one end sealing.
The oil groove place of described hood bottom also is provided with at least one oil-out.
Described oil-out below is provided with oil collection box.
The advantage that this enforcement is novel:
1, traditional fume purifying separation equipment is gathered on the integral device, the occupation of land space is little and install simple.
2, be provided with oil filtering grid when oil smoke enters, oil extraction better effects and if the fire that produces can prevent from cooking the time are scurried in the hood, avoid disaster hidden-trouble.
3, two at centrifugal blower arrange muffler plate, the voice that produces in the time of can effectively reducing centrifugal blower work.
4, the utility model can according to the smoke extractor of the customized all size of customer demand, when having many smoke exhaust ventilators in the back room of dining room, can work independently each other.
5, the utility model is contained in blower fan, cleaning equipment collection in the hood, and high efficiency has also been saved electric cost simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of smoke exhaust ventilator comprises hood 1, centrifugal blower 2, and described hood 1 below is provided with the oblique mouth 3 that advances, and describedly enters mouth 3 places and is provided with oil filtering grid 4; Described centrifugal blower 2 is positioned at hood 1 upper center, described centrifugal blower 2 tops or rear, hood middle part are provided with outlet flue 5, described centrifugal blower 2 the right and lefts, below and the place ahead is all sealed and about two sides be provided with muffler plate 6, mouth 7 is established back in described centrifugal blower 2 the place aheads, and described time mouth 7 both sides are provided with at least two filtering oil smoke cylinders 8 or cleaner; Described hood bottom and four limit peripheral frame are equipped with oil groove 9.
Described oil filtering grid 4 is the cube that two layers of corrosion resistant plate form, described oil filtering grid 4 two sides are equipped with the smoke intaking hole 10 of equirotal vertical arrangement, described two sides smoke intaking hole 10 is evenly staggered in vertical direction, and described oil filtering grid 4 both sides are equipped with oil outlet.
Described cartridge filter is comprised of steel wire cylinder 8 and macromolecular filtering cotton 11, and described macromolecular filtering cotton 11 is centered around steel wire cylinder 8 inboards, described steel wire cylinder 8 one ends sealing.
Oil groove 9 places of described hood bottom also are provided with at least one oil-out, and described oil-out below is provided with oil collection box.
The utility model is when implementing, centrifugal blower 2 work, oil smoke enters in the hood by advancing mouth 3, because it is vertically staggered to advance the smoke intaking hole 10 of the oil filtering grid 4 on the mouth 3, stopped when oil smoke enters like this, the part oil smoke condenses into oil droplet and flows to oil filtering grid below one end and flow to hood 1 bottom by the oil-out that arranges along the oil filtering grid inwall that tilts, and the oil-out that finally arranges by hood 1 bottom flows out; Some oil smoke enters cartridge filter 8, flows out after the filtration through macromolecular filtering cotton 11, and the mouth 7 that returns that arranges through centrifugal blower 2 the place aheads enters the centrifugal blower chamber and finally is discharged from outlet flue 5.Simultaneously, enter part oil smoke in the hood 1 through after condensing into oil droplet, also can slide along the oil groove 12 of hood 1 four limit peripheral frame settings to the oil groove of hood bottom, discharge by oil-out.
Macromolecular filtering cotton 11 in the utility model can change at any time as required and cost low.
The noise that muffler plate 6 in the utility model produces in the time of can effectively reducing centrifugal blower work.
Although above the specific embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned embodiment according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection domain of the present utility model.
