100 are arranged in dining area, easily and quickly aspirate the oil smoke generated in cooking process by range hood 100, improve dining
Comfort.Specifically, range hood 100 can be directly placed on dining table, can also be hung and be arranged above dining table.
As depicted in figs. 1 and 2, range hood 100 according to an embodiment of the invention, comprising: support 1, fan assembly
2, air intake assembly 4 and injection component 3.
Import 11 is formed on support 1, fan assembly 2 is located in support 1, and fan assembly 2 has air inlet 21 and outlet air
Mouth 22, air inlet 21 is connected to import 11.Optionally, fan assembly 2 is centrifugal blower component 2.The air inlet 21 of fan assembly 2
It can be formed in the side (for example, right side in Fig. 2) of fan assembly 2, the air outlet 22 of fan assembly 2 can be formed in blower
The top of component 2.When fan assembly 2 works, high speed can be blowed into the ejection cavity 34 of injection component 3 by fan assembly 2
And/or the air-flow of high pressure.That is, the gas of high speed or high pressure can be blowed into ejection cavity 34 when fan assembly 2 works
It flows, or blows the air-flow of high speed and high pressure into ejection cavity 34.
Referring to Fig.1, support 1 can be formed generally as rectangular parallelepiped structure, have the open accommodation space in top in support 1
12, fan assembly 2 is arranged in the accommodation space 12 of support 1.Specifically, import 11 can be set on the side wall of support 1, into
Mouth 11 can be formed as cell structure, but not limited to this.Thus, it is possible to be carried out by grid to the air entered in blower 2
Filter, reduces the impurity avoided in air into the impurity in blower 2 and damages to blower 2, improve the property of blower 2
Can, extend the service life of blower 2.
Air intake assembly 4 is located on support 1, air intake assembly 4 have at least one oil smoke entrance 41, oil smoke entrance 41 penetrate through into
The wall body of wind component 4.Wherein, oil smoke entrance 41 can be one or more.For example, in the example of fig. 1, oil smoke entrance 41
To be multiple, multiple oil smoke entrances 41 are distributed in air intake assembly 4.Optionally, multiple oil smoke entrances 41 can equably between
Every on the wall for being distributed in air intake assembly 4, specifically, multiple oil smoke entrances 41 scatter setting on the wall of air intake assembly 4.By
This, can increase the aspiration ranges of range hood 100, guarantee the oil smoke of all directions sucking air intake assembly 4, improve oil suction
The oil suction smoke performance of smoke machine 100.Optionally, oil smoke entrance 41 can be formed as round, oval, polygon or irregular component
Shape etc..
Injection component 3 is connected with air intake assembly 4, and injection component 3 is formed as hollow structure, and one end of injection component 3 is formed
There are air flow inlet 345, the other end to be formed with air stream outlet 346, air flow inlet 345 is connected to oil smoke entrance 41, injection component 3
