Abstract
The invention discloses an extractor hood which comprises a volute casing, a fan and a flow-distributing plate, wherein the volute casing defines an inner cavity and an air outlet; the inner cavity communicates with the air outlet; the fan is arranged in the inner cavity; and the flow-distributing plate is arranged at the air outlet. The flow-distributing plate can achieve flow-distributing effect at the air outlet, so that great vortex formed through the fan is cut into two or more small vortexes, and therefore, great vortex noises can be reduced; besides, the flow-distributing plate facilitates improving an uneven air flow pressure distribution condition at the air outlet, so that air flow efficiency at the extractor hood can be improved.
Description
Technical field
The present invention relates to a kind of range hood.
Background technology
With raising of the people to health perception, range hood for kitchen use has progressively become the requisite electricity of each family
Device.The big suction of Wind Volume of consumer's accreditation at present has become the main selling point in market, but range hood itself has wind
The bigger contradiction of the bigger noise of amount.Noise in daily life has had a strong impact on the life of people, kitchen as family
Individual core, should be one relatively quiet again full of the environment for cooking enjoyment, but the in fact maximum noise source in present kitchen
It is exactly range hood.It is more and more to the complaint of noise on market, seeking new noise reduction solution always in industry, but
System and structure construction in view of lampblack absorber itself, noise reduction is a very difficult thing.
The mode of existing range hood noise reduction has a lot, and most of design is all centrifugal fan structure, passive
Do on the basis of noise reduction technology, such as fan design, the passive sqouynd absorption lowering noise of range hood runner etc., but noise reduction is not clear
It is aobvious.
The content of the invention
It is contemplated that at least solving one of technical problem in correlation technique to a certain extent.For this purpose, the present invention is carried
Go out a kind of range hood, the range hood can cut big vortex in air outlet, can reduce noise.
Range hood of the invention, including：Spiral case, the spiral case limit inner chamber and air outlet, the inner chamber and
The air outlet connection；Blower fan, the blower fan are arranged on the inner chamber；Splitter, the splitter are arranged on the air outlet
Place.
Range hood of the invention, splitter can play shunting action in air outlet, so will can pass through
The Maelstrom formed after blower fan cuts into two or more little whirlpool, such that it is able to reduce Maelstrom noise, in addition, shunting
Piece also contributes to improving air outlet stream pressure situation pockety simultaneously, can lift the air stream at range hood
Efficiency of movement.
In addition, range hood of the invention can also have following distinguishing feature：
In some examples of the present invention, the splitter is in ellipsoid or willow leaf fusiformis shape.
In some examples of the present invention, the height of the splitter is less than the maximum height of the air outlet.
In some examples of the present invention, on the edge of the splitter, installation foot is provided with.
In some examples of the present invention, the installation foot is two and opens up in the circumferentially-spaced of the splitter
Put.
In some examples of the present invention, the installation foot is configured to sheet and is formed in one part with the splitter.
In some examples of the present invention, the splitter is welded or is bonded in the spiral case.
In some examples of the present invention, the splitter is rectangular slat shape or circular arc strip.
In some examples of the present invention, the base plate of the splitter and the spiral case is formed in one part.
In some examples of the present invention, the splitter is metalwork.

Specific embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings.Below with reference to
The embodiment of Description of Drawings is exemplary, it is intended to for explaining the present invention, and be not considered as limiting the invention.
Range hood 100 according to embodiments of the present invention is described in detail below with reference to Fig. 1-Fig. 6.
As shown in Fig. 1-Fig. 3 and Fig. 6, range hood 100 according to embodiments of the present invention can include：Spiral case 10, wind
Machine 20 and splitter 30, spiral case 10 limit inner chamber 11 and air outlet 12, and inner chamber 11 is connected with air outlet 12, and blower fan 20 is arranged on
Inner chamber 11, blower fan 20 can be centrifugal blower, and splitter 30 is arranged at air outlet 12.It is understood that on spiral case 10 also
Air inlet is provided with, the wind entered from air inlet can be entered in blower fan 20, from 12 row of air outlet in the presence of blower fan 20
Go out, wherein, splitter 30 can play shunting action at air outlet 12, so can be by the big whirlpool formed after blower fan 20
Whirlpool cuts into two or more little whirlpool, such that it is able to reduce Maelstrom noise, in addition, splitter 30 also contributes to simultaneously
Improve stream pressure situation pockety at air outlet 12, the air flow efficiency at range hood 100 can be lifted.
Wherein, as shown in Fig. 2 splitter 30 can be in ellipsoid or willow leaf fusiformis shape.The splitter 30 of above-mentioned shape
The smoothness that air-flow passes through is can aid in, loss and the noise of airflow strikes can be avoided, such that it is able to preferably reduce inhaling
The noise of lampblack absorber 100.Certainly, the present invention is not limited to this, and splitter 30 can also be that rectangular slat shape or circular arc are long
Strip.
Alternatively, as shown in Fig. 2 the height h1 of splitter 30 can be less than maximum height h2 of air outlet 12.So may be used
So that splitter 30 is suitable with the contact area of air-flow, while guaranteeing to cut Maelstrom, can avoid producing gas
The loss of stream collision and noise.
Alternatively, as shown in figure 4, installation foot 40 can be provided with the edge of splitter 30.Installation foot 40 can be direct
On the internal face of spiral case 10, by arranging installation foot 40, the installation reliability of splitter 30 is on the one hand can ensure that, separately
On the one hand the mounting means of splitter 30 can be caused simple, installation effectiveness height.
Specifically, as shown in Fig. 1, Fig. 3 and Fig. 5, installation foot 40 can be two, and two installation feet 40 are in splitter
30 circumferentially-spaced opening up is put.Two installation feet 40 may be mounted on the internal face on the different directions of spiral case 10, so
The installation reliability of splitter 30 can preferably be improved.
Preferably, as shown in figure 4, installation foot 40 is so structured that sheet, and installation foot 40 is integrated with splitter 30
Profiled member.The installation foot 40 of sheet preferably can be abutted on the internal face of spiral case 10, such that it is able to improve splitter 30
Installation reliability, 30 simple structure of integrally formed installation foot 40 and splitter are easily manufactured.
Certainly, splitter 30 can also be fixed on the internal face of spiral case 10, for example by other means, and splitter 30 can
To weld the internal face of spiral case 10, and for example, splitter 30 can be bonded in the internal face of spiral case 10.
Alternatively, the base plate of splitter 30 and spiral case 10 is formed in one part.Such base plate of splitter 30 and spiral case 10
Between structure reliability, such that it is able to improve reliability of the splitter 30 at air outlet 12.
Alternatively, splitter 30 can be metalwork.Made by metal, splitter 30 can bear the temperature that air-flow is carried,
Can so cause the functional reliability of range hood 100 preferable.
