Description
Technical field
The utility model relates to a kind of device for filtering, purifying air, specifically a kind of tower range hood with lampblack filtering function.
Background technology
The oil smoke mode of discharging is by existing range hood: one is first discharged to common flue by smoke exhaust pipe, outdoor is discharged to again by common flue, owing to there is no good filtering oil smoke technology, service time one, length can accumulate a large amount of greasy dirts at smoke exhaust pipe and common flue place, finally cause the breeding of a large amount of bacterium and give out various peculiar smell, and the oil smoke of discharging finally is discharged to and outdoor pollutes to air.Another kind is that oil smoke is directly discharged to outdoor, and due to not through common flue, the oil smoke of discharge particularly upper and lower floor can mutual taint of odour, causes serious pollution especially.Some lampblack absorber also has the effect of filtering oil smoke at present, but actual is added one deck screen pack or adopt the two-layer net that staggers in guard, oil smoke just be have passed through the thick filtration of one deck by its final effect of the filter type of this static state, do not have complete oil smoke to be separated, the oil smoke of discharge still has very large pollution.Disclosed in 19 days January in 2011 of Patent Office of the People's Republic of China, the patent No. is " near-suction type smoke purifier " of " ZL2009100611042 ", its feature is: be separately installed with output shaft turbofan in vertical state in two isolated chamber of spiral case, and the output shaft lower end of described turbofan is stretched out outside duplex spiral case, on it and is connected with at least one rotary and centrifugal type filter screen disk be the level of state; Although this structure can be tackled and be collected oil smoke, its filter screen disk is mounted on the output shaft of turbofan, rocks large easily shake and noise is large during rotation.
Summary of the invention
The purpose of this utility model is defect for above-mentioned prior art and deficiency, for people provide a kind of tower range hood with lampblack filtering function.
Technical solution adopted in the utility model is for achieving the above object: this has the tower range hood of lampblack filtering function, it comprises the housing of range hood, the screen pack of back taper is provided with in the bottom of housing, the lower end of screen pack is provided with lubricating cup, in housing, centrifugal fan is installed, this centrifugal fan comprises the Blower Housing with air inlet and air outlet, motor and wind wheel, air-ducting ring is provided with on front side of the air inlet of described centrifugal fan, air-ducting ring is provided with bracing frame, this bracing frame is provided with a dynamic fan blade, described dynamic fan blade is relative with the air intake direction of centrifugal fan, air flow energy promotes dynamic fan blade and rotates, the outside of described dynamic fan blade is provided with oil blocking cover, offers oil dripping mouth in the bottom of oil blocking cover, is provided with oil dripping funnel in the below of centrifugal fan and oil blocking cover, and the bottom oil-out of this oil dripping funnel is positioned at the top of lubricating cup.
Described dynamic fan blade comprises blade shaft and at least one group blade fixing with blade shaft, is provided with the locking nut be connected with blade shaft in the front side of blade.
Described dynamic fan blade is positioned at the front side of air-ducting ring.
Described oil blocking cover is in horizontal cylindrical shape.
Described dynamic fan blade external diameter is greater than air-ducting ring.
The utility model sucks the oil smoke in kitchen by centrifugal fan, oil smoke is through dynamic fan blade, dynamic fan blade can be driven to rotate, oil droplet can condense on the blade of the dynamic fan blade rotated in friction, then get rid of under the influence of centrifugal force to oil blocking cover, oil smoke is separated from air-flow, and final oil droplet flows into lubricating cup by the inwall of oil blocking cover.Because dynamic fan blade is driven by air-flow; the windage caused air-flow is very little, therefore can not produce too large noise, has that structure is simple, easy to clean, reliable, long working life; substantially the pollution of oil smoke to air and external wall can be stopped, for environmental protection is made contributions.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A direction view of Fig. 1.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the utility model is a kind of tower range hood with lampblack filtering function, and it comprises the housing 11 of range hood, is provided with the screen pack 12 of back taper in the bottom of housing 11, and the lower end of screen pack 12 is provided with lubricating cup 13.In housing 11, be provided with centrifugal fan, this centrifugal fan comprises with the Blower Housing 1 of air inlet and air outlet, the wind wheel 5 that is installed on the motor 7 in Blower Housing 1 and is arranged on the output shaft 6 of motor 7.During centrifugal fan work, moving air flow can be with to enter housing 11 from screen pack 12, by discharging from air outlet after centrifugal fan.
Be provided with air-ducting ring 2 on front side of described air inlet, air flow energy taken advantage of a situation and enters air inlet, prevent from colliding with Blower Housing 1 producing noise.Air-ducting ring 2 is provided with bracing frame 3, this bracing frame 3 is provided with a dynamic fan blade 4, described dynamic fan blade 4 comprises blade shaft 4.3 and at least one group blade 4.1 fixing with blade shaft 4.3, is provided with the locking nut 4.2 be connected with blade shaft 4.3 in the front side of blade 4.1.Described dynamic fan blade 4 is relative with the air intake direction of centrifugal fan, and air flow energy promotes dynamic fan blade 4 and rotates.Air-flow is when the dynamic fan blade 4 of over-rotation, and oil droplet can condense on the blade 4.1 of the dynamic fan blade 4 rotated in friction, then gets rid of under the influence of centrifugal force to surrounding, oil smoke is separated from air-flow.Described dynamic fan blade 4 external diameter is greater than air-ducting ring 2, makes dynamic fan blade 4 can cover air intake passage as far as possible, improves clean-up effect.If when the oil smoke content in air-flow is more, dynamic fan blade 4 can arrange two groups or more blade 4.1, blade 4.1 axially installing side by side at blade shaft 4.3.Described dynamic fan blade 4 is positioned at the front side of air-ducting ring 2, prevents oil droplet to be thrown in air-ducting ring 2.
The outside of described dynamic fan blade 4 is provided with oil blocking cover 8, and the centrifugal oil droplet thrown away is thrown to the inwall of oil blocking cover 8.Described oil blocking cover 8 is in horizontal cylindrical shape, and oil droplet, easily along the downward landing of inwall of oil blocking cover 8, avoids drippage.Offer oil dripping mouth 9 in the bottom of oil blocking cover 8, be provided with oil dripping funnel 10 in the below of centrifugal fan and oil blocking cover 8, the bottom oil-out of this oil dripping funnel 10 is positioned at the top of lubricating cup 13, arrives lubricating cup 13 from the oil droplet of oil dripping mouth 9 drippage through funnel 10.
The utility model sucks the oil smoke in kitchen by centrifugal fan, oil smoke is when dynamic fan blade 4, dynamic fan blade 4 can be driven to rotate, oil droplet can condense on the blade 4.1 of the dynamic fan blade 4 rotated in friction, then get rid of under the influence of centrifugal force to oil blocking cover 8, the inwall eventually through oil blocking cover 8 flows into lubricating cup 9.Because dynamic fan blade 4 is driven by air-flow; the windage caused air-flow is very little, therefore can not produce too large noise, has that structure is simple, easy to clean, reliable, long working life; substantially the pollution of oil smoke to air and external wall can be stopped, for environmental protection is made contributions.
