Degree.
Content of the invention
Technical problem to be solved in the utility model is that the present situation for prior art provides a kind of air supplying distance short
Cleaning helps suction range hood.
This utility model solves the technical scheme that adopted of above-mentioned technical problem：This cleaning helps suction range hood, including
The air-supply arrangement being arranged in the exhaust fume collecting hood of range hood and blowing downwards, described air-supply arrangement includes blower fan；Its feature exists
It is axial flow blower in described blower fan, described blower fan is connected on telescopic component,
Described exhaust fume collecting hood is to the position of blower fan should having hole；
Described telescopic component can stretch out with described blower fan under the driving of driving means, the hole described in indentation.
Described driving means preferably employ motor.
Telescopic component in such scheme can have multiple, and preferably, described telescopic component includes defeated with described motor
The gear that shaft is connected, described gear pinion rack, the lower end of described tooth bar connects described blower fan.Program structure is simple,
Reliable in action.
Preferably, described air-supply arrangement can also include connecting seat, and described blower fan is arranged in the cavity of described connecting seat,
The air inlet of described cavity is communicated with the wall of described connecting seat, the bottom surface of described connecting seat is communicated with described cavity and
Downward opening outlet passageway；
Described connecting seat connects described telescopic component.
For being further ensured that the cleanliness factor of the air-flow blowing in pot, filter screen can be provided with described air inlet.By filter
The impurity of net filtration in the air, it is to avoid the little particle such as dust of in the air blows in pot, further ensures the clean of blow flow
Cleanliness.
The cross section of preferably described outlet passageway is in flat ring-type.
Preferably, described outlet passageway is fan annular, and the interior arc radius of described outlet passageway are 100～200mm, described go out
The width of gas passage is 5～20mm.This structure can be adapted to the shape of pan well, along the outer ledge of pan to pot in
Blowing, it is more preferable that oil smoke pushes effect.
Described outlet passageway can externally protrude out in the bottom surface of described connecting seat, and this design makes the distance that blows of air-supply air-flow enter
One step shortens, and effectively prevent in air-supply airflow blow way and is broken up by external disturbance.
Compared with prior art, cleaning provided by the utility model helps suction range hood operationally, air-supply arrangement position
Outside exhaust fume collecting hood, from surrounding draw air be blown into domestic it is ensured that the cleanliness factor of blow flow, thus ensureing domestic
The wholesomeness of institute's cooking food；And, in the presence of retractor device, air-out position when significantly reducing air-supply arrangement work,
Enable that the air-flow that air-supply arrangement is sent is in-plant to be directly blown in pot, it is to avoid the disturbance of external air flow, effectively
Ensure that and help suction effect.

Specific embodiment
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As shown in Figures 1 to 4, this cleaning helps suction range hood to include being arranged on the air-supply in the exhaust fume collecting hood 1 of range hood
Device 2, driving means 4 and telescopic component 3；The bottom surface of exhaust fume collecting hood 1 is provided with the hole 11 for air-supply arrangement into and out of exhaust fume collecting hood 1.
Wherein,
Air-supply arrangement 2, including blower fan 21 and connecting seat 22；Blower fan 21 is axial flow blower, and blower fan 21 is arranged on connecting seat 22
Cavity 23 in, the wall of connecting seat 22 is communicated with the air inlet 24 of cavity 23, air inlet 24 is provided with filter screen, and (in figure is not shown
Go out), the bottom surface of connecting seat 22 is communicated with cavity 23 and downward opening outlet passageway 25.
In the present embodiment, outlet passageway 25 externally protrudes out in the bottom surface of connecting seat 22, and its cross section is fan annular, outlet passageway 25
