Description
Technical field
The utility model relates to a kind of air draught purifier used for range hood.
Background technology
In prior art, the oil smoke produced during culinary cuisine is taken away and is drained into outdoor by the air draught purifier that range hood generally adopts centrifugal fan group to be formed, and reduces its pollution to room air.When oil smoke is larger, usually the motor speed improving air draught purifier is needed, and wind speed larger time, more easily produce disorderly air-flow in exhaust fume collecting hood, each parts of these air-flows easily and in exhaust fume collecting hood produce and collide, especially to the shock bottom air draught purifier, thus cause noise acutely to increase, the final comfortableness affecting range hood and use, therefore, also requires further improvement.
Utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, and the air draught purifier used for range hood that noise is low, filtering oil smoke is effective, to overcome weak point of the prior art.
By the air draught purifier a kind of used for range hood that this object designs, comprise motor, be connected to the impeller on its turning cylinder and wrap both spiral case, the position of the corresponding impeller in front side of spiral case is provided with air inlet, top side is provided with air outlet, inner formation one air-suction channel, its architectural feature is, spiral case bottom side is extended with a sound-absorbing damping chamber downwards, sound-absorbing damping chamber and air-suction channel are spaced from each other, and are filled with sound absorbing layer in this sound-absorbing damping chamber.
Described sound-absorbing damping chamber is del chamber.
The madial wall of described spiral case is coated with sound absorbing layer.
Described sound absorbing layer is made up of acoustical cotton or acoutic fibre board.
The turning cylinder of described motor is also connected with oil fume separator, and it is positioned at the front side of impeller.
Described air inlet is also provided with the annular Oil Guide lid for covering oil fume separator edge, is provided with oil fume separator outage bottom Oil Guide lid and between spiral case sidewall.
The bottom of described air-suction channel is provided with air draught purifier outage.
Described air draught purifier is inclined in the exhaust fume collecting hood of range hood.
The utility model has following beneficial effect:
1, air draught purifier adds for cushioning disorderly air-flow to the sound-absorbing damping cavity clashed into bottom air draught purifier, and the noise that motor and impeller are produced when running up drops to a desirable level.
2, air draught purifier carries the wind wheel of motor and the overweight wide blade that can run up, and makes air quantity, total pressure efficiency (product of total head value namely when the regulation air quantity (7m3/min) of range hood and regulation air quantity under air standard state and the ratio of mair motor input power during regulation air quantity) and efficiency reach an optimum state.
Sucked oil smoke can be carried out isolation of purified by the oil fume separator that 3, the air inlet of air draught purifier is installed, and oil smoke separating degree is brought up to more than 99%.
Accompanying drawing explanation
Fig. 1 is the stereogram of the utility model one embodiment air draught purifier.
Fig. 2 is the structural representation (analysing and observe) of Fig. 1.
Fig. 3 is the schematic diagram (analysing and observe) that air draught purifier is applied on range hood.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
See Fig. 1-Fig. 3, this air draught purifier used for range hood, comprise motor 1, be connected to the impeller 2 on its turning cylinder and wrap both spiral case 3, the position of the corresponding impeller in front side of spiral case 3 is provided with air inlet 32, top side is provided with air outlet 33, inner formation one air-suction channel, and spiral case 3 bottom side is extended with a sound-absorbing damping chamber 31 downwards, sound-absorbing damping chamber 31 and air-suction channel are spaced from each other, and are filled with sound absorbing layer 4 in this sound-absorbing damping chamber 31.
This air draught purifier is inclined in the exhaust fume collecting hood 10 of range hood, motor 1 is when high-speed rotation, the wind speed produced is larger, now, easily disorderly air-flow is produced in exhaust fume collecting hood 10, each parts in these air-flows and exhaust fume collecting hood 10 produce and collide, especially (wind speed at exhaust fume collecting hood 10 top is greater than because of the wind speed bottom exhaust fume collecting hood 10 to the shock bottom air draught purifier, therefore the vibrations that produce of this position and noise the most serious), and this air draught purifier is provided with sound-absorbing damping chamber 31 bottom spiral case 3, for cushioning above-mentioned collision, greatly reduce the vibrations and noise that bring this position, thus more can improve the comfortableness of range hood use.Also because noise can significantly reduce, therefore, air draught purifier can carry the wind wheel of motor and the overweight wide blade that more can run up, and makes air quantity, total pressure efficiency and efficiency reach an optimum state.
Further, sound-absorbing damping chamber 31 is del chamber, by this technical scheme, can guide the disorderly well-regulated flowing of air-flow further, thus is more conducive to cushioning above-mentioned collision, more can reduce the vibrations brought this position and noise.
Further, the madial wall of spiral case 3 is coated with sound absorbing layer 4, and spiral case 3 covering sound absorbing layer 4 as much as possible, can reduce the collision of said flow to other positions of spiral case 3 further, the vibrations that these positions of effective reduction are brought and noise, thus the comfortableness that more can improve range hood use.
Further, sound absorbing layer 4 is made up of acoustical cotton or acoutic fibre board.
Further, the turning cylinder of motor 1 is also connected with oil fume separator 5, it is positioned at the front side of impeller 2.Sucked oil smoke can be carried out isolation of purified by oil fume separator 5, and oil smoke separating degree is brought up to more than 99%
Further, air inlet 32 is also provided with the annular Oil Guide lid 6 for covering oil fume separator 5 edge, when Oil Guide lid 6 can prevent oil fume separator 5 from working, the oil smoke (water) that its marginal position throws away splashes, and the oil smoke (water) thrown away can be guided toward dirty, oil fume separator outage (not marking in figure) is provided with, for the oil extraction of Oil Guide lid 6 bottom Oil Guide lid 6 and between spiral case 3 sidewall.
Further, the bottom of air-suction channel is provided with air draught purifier outage (not marking in figure), for the oil extraction of air-suction channel.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
