Description
Technical field
The present invention relates to a kind of air draught purifier used for range hood.
Background technology
In the prior art, when the air draught purifier that range hood is generally formed using centrifugal fan group is by culinary cuisine
Caused oil smoke, which is taken away, drains into outdoor, reduces its pollution to room air.When oil smoke is larger, it usually needs improve air draught
The motor speed of purifier, and when wind speed is bigger, it is easier in exhaust fume collecting hood to produce disorderly air-flow, these air-flows easily with
Each part in exhaust fume collecting hood, which produces, to be collided, the especially shock to air draught purifier bottom, so as to cause noise acutely to increase,
The final comfortableness for influenceing range hood and using, therefore, it is also desirable to further improve.
The content of the invention
The purpose of the present invention aims to provide a kind of simple and reasonable, range hood that noise is low, filtering oil smoke effect is good
Air draught purifier, to overcome weak point of the prior art.
A kind of air draught purifier used for range hood designed by this purpose, including motor, be connected in its rotary shaft
Impeller and wrap both spiral cases, the position that the front side of spiral case corresponds to impeller is provided with air inlet, and top side is provided with air outlet, interior
Portion forms an air-suction channel, and its architectural feature is, spiral case bottom side has extended downwardly a sound-absorbing damping chamber, and sound-absorbing damping chamber is with inhaling
Wind passage is spaced from each other, and the sound-absorbing damping intracavitary is filled with sound absorbing layer.
The sound-absorbing damping chamber is del chamber.
The madial wall of the spiral case is covered with sound absorbing layer.
The sound absorbing layer is made up of acoustical cotton or acoutic fibre board.
Oil fume separator is also associated with the rotary shaft of the motor, it is located at the front side of impeller.
The air inlet is additionally provided with the annular Oil Guide lid for covering oil fume separator edge, Oil Guide base portion and spiral case side
Oil fume separator outage is provided between wall.
The bottom of the air-suction channel is provided with air draught purifier outage.
The air draught purifier is inclined in the exhaust fume collecting hood of range hood.
The invention has the advantages that：
1st, air draught purifier adds the sound-absorbing damping hit for buffering disorderly air-flow to air draught purifier bottom
Cavity, motor and impeller is set to drop to a desirable level in the caused noise that runs at high speed.
2nd, air draught purifier carries the wind wheel of the motor that can be run at high speed and overweight wide blade, makes air quantity, total pressure efficiency
(i.e. the regulation air quantity (7m3/min) of range hood and regulation air quantity when air standard state under total head value product and regulation
The ratio of main motor input power during air quantity) and efficiency reach an optimum state.
3rd, the oil smoke sucked can be carried out isolation of purified by the oil fume separator of the air inlet installation of air draught purifier,
Oil smoke separating degree is brought up to more than 99%.
Brief description of the drawings
Fig. 1 is the stereogram of one embodiment of the invention air draught purifier.
Fig. 2 is Fig. 1 structural representation (section view).
Fig. 3 is that air draught purifier applies the schematic diagram (section view) on range hood.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Referring to Fig. 1-Fig. 3, this air draught purifier used for range hood, including motor 1, the leaf that is connected in its rotary shaft
Wheel 2 and wrap both spiral cases 3, the position that the front side of spiral case 3 corresponds to impeller is provided with air inlet 32, and top side is provided with air outlet
33, an air-suction channel is internally formed, the bottom side of spiral case 3 has extended downwardly a sound-absorbing damping chamber 31, and sound-absorbing damping chamber 31 leads to air draught
Road is spaced from each other, and sound absorbing layer 4 is filled with the sound-absorbing damping chamber 31.
This air draught purifier is inclined in the exhaust fume collecting hood 10 of range hood, and motor 1 is caused in high-speed rotation
Wind speed is larger, and now, the content of exhaust fume collecting hood 10 is also easy to produce the air-flow of disorder, and these air-flows are produced with each part in exhaust fume collecting hood 10 and touched
Hit, the shock especially to air draught purifier bottom is (because the wind speed of the bottom of exhaust fume collecting hood 10 is more than the wind at the top of exhaust fume collecting hood 10
Speed, therefore vibrations and noise are the most serious caused by the position), and this air draught purifier is provided with sound-absorbing in the bottom of spiral case 3
Damping chamber 31, for buffering above-mentioned collision, vibrations and noise caused by the position are substantially reduced, so as to can more improve fume-exhausting
The comfortableness that machine uses.Also due to noise can be greatly lowered, therefore, air draught purifier can carry the electricity that can more run at high speed
The wind wheel of machine and overweight wide blade, air quantity, total pressure efficiency and efficiency is set to reach an optimum state.
Further, sound-absorbing damping chamber 31 is del chamber, by the technical scheme, can further guide disorder
The well-regulated flowing of air-flow, so as to be more beneficial for buffering above-mentioned collision, it can more reduce vibrations and noise caused by the position.
Further, the madial wall of spiral case 3 the covering sound absorbing layer 4 as much as possible of spiral case 3, can enter one covered with sound absorbing layer 4
Step reduces collision of the said flow to the other positions of spiral case 3, vibrations and noise caused by these positions is effectively reduced, so as to more
The comfortableness that range hood uses can be improved.
Further, sound absorbing layer 4 is made up of acoustical cotton or acoutic fibre board.
Further, oil fume separator 5 is also associated with the rotary shaft of motor 1, it is located at the front side of impeller 2.Oil smoke point
The oil smoke sucked can be subjected to isolation of purified from device 5, oil smoke separating degree is brought up to more than 99%
Further, air inlet 32 is additionally provided with the annular Oil Guide lid 6 for covering the edge of oil fume separator 5, the energy of Oil Guide lid 6
When enough preventing that oil fume separator 5 from working, the oil smoke (water) that its marginal position is thrown away splashes, and can guide thrown away oil smoke
(water) is provided with oil fume separator outage (not marked in figure), for leading toward flowing down between the bottom of Oil Guide lid 6 and the side wall of spiral case 3
The oil extraction of oil cap 6.
Further, the bottom of air-suction channel is provided with air draught purifier outage (not marked in figure), leads to for air draught
The oil extraction in road.
The above disclosed right for being only the preferred embodiments of the present invention, the present invention can not being limited with this certainly
Scope, therefore the equivalent variations made according to scope of the present invention patent, still belong to the scope that the present invention is covered.
