Specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
Embodiment 1
As shown in Figure 1 to Figure 3, the hood with liftable exhaust fume collecting kitchen hood includes：
Casing 2, for housing blower fan 1, while playing a part of discharge flue, its cross section is rectangle, naturally it is also possible to
Other shapes are designed as needed.
Blower fan 1, is two-way centrifugal blower, for aspirating oil smoke；It is contained in casing 2, the forward and backward side of blower fan 1 and casing
The gap for ventilation is respectively provided between wall；Gap in the present embodiment between blower fan and casing rear wall less than with front side wall it
Between gap.Certainly, the big I in two gaps is designed as needed.
Wind deflector 6, is connected to the lower section of the housing of blower fan 1, is contained in casing 2, for blower fan 1 former and later two
Air inlet water conservancy diversion；The cross section of wind deflector 6 is triangle, and the upper edge for constituting two pieces of swash plates of its lower end wedge angle connects wind respectively
The both sides lower limb of machine 1.
Exhaust fume collecting hood 3, is the conventional components of lampblack absorber, for shielding and to 2 Inner guide oil smoke of casing.
Set chimney 4, is connected to the top of exhaust fume collecting hood 3 and upper and lower slidably can be set in casing 2, collects in the present embodiment
Chimney 4 is integrally formed with exhaust fume collecting hood 3；The height of set chimney 4 is more than the minimum range between blower fan 1 and the lower port of casing 2.
Telescopic component 5, has one group, for driving set chimney 4 and exhaust fume collecting hood to move up and down relative to casing 2, is arranged on machine
On the outer wall of shell 2 and exhaust fume collecting hood 3；Including the tooth bar 51 being fixedly connected in casing 2, the motor being fixed on exhaust fume collecting hood 3
52 and connection motor 52 output shaft gear 53；51 meshing gear 53 of tooth bar；The shell of motor 52 is provided with use
In the upper limit position block 54 and lower position block 55 that limit 52 displacement of motor.Upper and lower limited block spacing can also be opened using upper and lower
Close to replace.
Guide rail 7, has two groups, is arranged on the both sides of telescopic component, for auxiliary positioning casing 2 and set chimney 4, exhaust fume collecting hood 3,
Including the guide pin bushing 71 being fixed in casing 2, guide rod 72 slides spacing in guide pin bushing 71, and guide pin bushing 72 is fixedly connected on exhaust fume collecting hood
On 3.
When needing to move down set chimney, button press (not shown), motor obtain electric work, drive gear relative to
Tooth bar is moved down, and so as to drive exhaust fume collecting hood to drive set chimney to move down together, guide rod is moved down and stretches out guide pin bushing；When lower position block touches tooth
During the lower ora terminalis of bar, motor stops operating, and set chimney stretches out, and the distance between exhaust fume collecting hood and kitchen range reduce；Be conducive to taking out
Fume-exhausting；Simultaneously because the height of set chimney is produced more than the minimum range between blower fan and the lower port of casing, therefore blower fan
Negative pressure sink, extend out and drain on the downside of set chimney so that on the downside of kitchen hood and edge negative pressure distribution obtain weight
Structure and improvement, the suction effect of oil smoke are significantly improved.
Oil smoke is entered in casing via exhaust fume collecting hood, set chimney, in the presence of wind deflector, swimmingly enter into blower fan with
In the forward and backward gap of casing, Jing fan outlets are discharged；The design of wind deflector reduces windage, while can be effectively reduced making an uproar
Sound.
Using finishing, button press, motor reversion drive；When upper limit position block touches tooth bar
During upper edge, motor stops operating, in set chimney retraction casing.
