Specific embodiment
The present invention will be described for following embodiment, but the present invention is not limited to these examples system.To of the invention
Specific embodiment is modified or some technical features can be equivalently replaced, without departing from the spirit of the present invention program,
It should all cover within the scope of the technical scheme claimed by the invention.
Embodiment one: as shown in Figures 1 to 6, the present embodiment provides a kind of smoke evacuation systems of range hood, comprising:
Range hood 1, range hood 1 have smoke outlet；
Smoke exhaust pipe 2, smoke exhaust pipe 2 is for smoke outlet to be connected to common flue 3；
Check valve assembly 4, check valve assembly 4 are set to the end of smoke exhaust pipe 2 for connecting smoke exhaust pipe 2 and common flue 3
Logical, check valve assembly 4 includes flue wind wheel 41, smoke pipe wind wheel 42 and shaft 43, and wherein flue wind wheel 41 is set to common flue 3
The inside, smoke pipe wind wheel 42 are set to 2 the inside of smoke exhaust pipe, and shaft 43 is used to flue wind wheel 41 and smoke pipe wind wheel 42 being connected to one
It rises.
The smoke evacuation system of the range hood of the present embodiment, structure is simple, and smoke discharging effect is ideal.In range hood Homes Using TV
In higher situation, the internal pressure of common flue 3 is big, and there are zooming flue gas, the flue gases inside common flue 3 at this time
Flue wind wheel 41 will be will drive to rotate, flue wind wheel 41 rotates and then smoke pipe wind wheel 42 is driven to rotate, and is achieved in smoke exhaust pipe increasing
Pressure increases the effect of air quantity, it is ensured that range hood can be worked normally so that the oil smoke in kitchen to be discharged in time.Smoke evacuation system of the invention
It unites under the working condition for needing most pressurization increasing air quantity, according to the flow behavior of common flue inside smoke, is risen using flue gas
Power, realize smoke exhaust pipe pressurization increase air quantity effect, abandoning tradition by increase motor active boost usual manner, thus
Cost can be reduced.
Specifically, the range hood 1 of every layer of user of a building can all access common flue 3, and when peak period of cooking, one
The user of building is discharged into flue gas, flue gas meeting vertical ascent flowing, due to the flue wind wheel 41 of check valve assembly 4 to common flue
It is arranged in common flue 3, under the impact for rising flue gas stream, the meeting high speed rotation of flue wind wheel 41 is then driven coaxial
42 high speed rotation of smoke pipe wind wheel.So that smoke pipe wind wheel 42 rotates in the case where range hood does not start, it can be from kitchen
Intake-gas is drained into common flue, so that common flue flue gas be avoided to flow backward into kitchen, has prevented kitchen taint of odour phenomenon.And
In range hood starting, the fan inside smoke pipe wind wheel 42 and range hood will form series connection blower fan system, reach pressurization
Purpose, and then reach the purpose for ensuring that range hood can be worked normally so that the oil smoke in kitchen to be discharged in time.
Preferably, check valve assembly 4 further includes non-return valve shell 44 and non-return valve blade 45, the shape in non-return valve shell 44
At discharge flue 440, non-return valve blade 45 is rotatably set to the inside of discharge flue 440 and is configured from smoke exhaust pipe 2 toward public
It unidirectionally opens in 3 direction of flue.When 1 need of work of range hood smoke evacuation when, non-return valve blade 45 open discharge flue 440 in favor of
Flue gas is smoothly discharged.When range hood 1 stops discharging fume, non-return valve blade 45 closes discharge flue 440 to avoid public cigarette
Road flue gas flows backward into kitchen, and structure is simple, and design is reasonable, ingenious, guarantees the smoke evacuation performance of smoke evacuation system.
It is furthermore preferred that being provided with connecting plate 441 inside discharge flue 440, air-flow is respectively formed in 441 two sides of connecting plate
Channel 442 is provided with non-return valve blade 45 at airflow channel 442, and non-return valve blade 45 is used to open or closed gas flow is logical
Road 442, structure is simple, and design is reasonable, ingenious, guarantees the smoke evacuation performance of smoke evacuation system.
In the present embodiment, the middle position of connecting plate 441 is provided with axis hole 4410, shaft 43 is arranged in axis hole
In 4410, the installation of shaft 43 is conducive to by the axis hole 4410 of setting, and can play a supporting role, support shaft 43 and be located at
The flue wind wheel 41 and smoke pipe wind wheel 42 at 43 both ends of shaft, so that flue wind wheel 41 and smoke pipe wind wheel 42 can more smoothly turn
Dynamic, work.
Further, it is provided with baffle 443 on the surface in connecting plate 441 towards 3 side of common flue, stopped for limiting
Return the open angle of valve blade 45.Particularly, when non-return valve blade 45 fully opens airflow channel 442, airflow channel 442 is supported
On the baffle 443, non-return valve blade 45 is limited by baffle 443 and is further rotated, thus can avoid non-return valve blade 45
Interfere with the rotation of shaft 43.
Further, baffle 443 includes at least two, is located at 441 two sides of connecting plate, and thus, it is possible to more reasonable
The open angle for limiting non-return valve blade 45, avoids non-return valve blade 45 from interfering with the rotation of shaft 43.
In the present embodiment, ring baffle 444 outstanding is provided on the inner wall of discharge flue 440, in ring baffle
Mounting plate 445 is symmetrically arranged on 444,45 both ends of non-return valve blade are rotatably connected with mounting plate 445 respectively.Particularly, exist
Mounting hole is offered on mounting plate 445, and is respectively arranged with axle portion at 45 both ends of non-return valve blade, and axle portion is rotatablely arranged at
Inside mounting hole, it is achieved in and non-return valve blade 45 is rotatablely arranged at 440 the inside of discharge flue, structure is simple, peace
It is convenient to fill.
Particularly, flue wind wheel 41 is horizontally disposed and perpendicular to the ascent direction of flue gas in common flue 3, thus may make
The flue gas that vertical ascent flows in common flue can preferably drive flue wind wheel 41 to rotate, and then be conducive to reach realization smoke exhaust pipe
Pressurization increases the purpose of the effect of air quantity.
In the present embodiment, flue wind wheel 41 includes the central axis 411 for connecting with shaft 43 and the setting of multiple intervals
Fan blade 412 on 411 periphery of central axis, central axis 411 are horizontally disposed and perpendicular to the rising side of flue gas in common flue 3
To.Preferably, the cross section of fan blade 412 is arc-shaped, thus can increase the contact of fan blade 412 with rising flue gas in common flue 3
Area so that rising flue gas in common flue 3 is easier to that wind wheel 41 is driven to rotate, and then is conducive to reach and realizes that smoke exhaust pipe pressurization increases wind
The purpose of the effect of amount.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, and these are all within the scope of protection of the present invention.
