Embodiment
Below in conjunction with the elaboration that Fig. 1 ~ Fig. 5 carries out specifically to technological scheme provided by the invention, arbitrary technological means provided by the invention is carried out replace or all should within protection scope of the present invention by the technological scheme that two or more technological means or technical characteristics carry out mutually combining and obtain provided by the invention arbitrarily.
The embodiment of the present invention provides a kind of extractor fan 1, and it is included in centrifugal blower 3 and axial-flow blower that air intake direction is connected.Wherein, centrifugal blower 3 is for increasing the blast of air entering extractor fan, and axial-flow blower is for increasing the air quantity of air entering extractor fan.
Axial-flow blower refers to the blower fan having and can increase the function of the air quantity entering into extractor fan.
The extractor fan 1 that technique scheme provides, there is the axial-flow blower that can increase air quantity and the centrifugal blower that can increase blast simultaneously, so the air quantity of the air entering extractor fan and blast can be made all to increase, improve the exhausting effect of extractor fan 1, and then add the smoke absorption effect of the kitchen ventilator using this extractor fan 1.
Further, on air intake direction, before the intake grill of axial-flow blower is positioned at the intake grill of centrifugal blower 3.Namely air is introduced into axial-flow blower, after enter centrifugal blower 3.By putting the axial-flow blower in front end, utilizing the Wind Volume characteristic of axial-flow blower, reaching smaller power and can reach Wind Volume exhausting effect; By being arranged on the centrifugal blower 3 of rear end, pressure treatment is carried out to the air entering extractor fan.By reaching the effect of the comprehensive utilization Wind Volume of axial-flow blower, the large blast of centrifugal blower 3 above, the air entering extractor fan 1 is made namely to have enough air quantity, there is again enough blast, meet kitchen ventilator and there is the usage requirement of household electric appliance of similar demand.
Herein, axial-flow blower specifically comprises impeller unit 2.The first end of the central shaft 31 of centrifugal blower 3 extends out to the shell 32 stretching out centrifugal blower 3, and the first end of the central shaft 31 of centrifugal blower 3 is provided with impeller unit 2.Second end of the central shaft 31 of centrifugal blower 3 drives with the motor 6 of centrifugal blower 3 and is connected.
Centrifugal blower 3 has central shaft 31, shell 32, the motor 6 driving this central shaft 31 to rotate and spiral case 4, and spiral case 4 has outlet and entrance.Shell 32 is arranged on central shaft 31, and can rotate along with the rotation of central shaft 31.Shell or be called wind wheel.
After adopting said structure, can impeller device 2 synchronous axial system when motor 6 drives central shaft 31 to rotate.
Impeller unit 2 has the effect increasing air quantity.The concrete structure of impeller unit 2 can have multiple, such as directly adopts the impeller unit in existing axial-flow blower, or adopts newly-designed wheel hub, blade structure.
After centrifugal blower 3 is started working, extraneous wind enters into centrifugal blower 3 via impeller unit 2, is then discharged by the outlet (i.e. the outlet of the spiral case 4 of centrifugal blower 3) of centrifugal blower 3.Air quantity through the wind of impeller unit 2 is increased, and the blast through the wind of centrifugal blower 3 is increased.
Introduce the alternate configurations of impeller unit 2 below.
Impeller unit 2 specifically comprises wheel hub 22 and is fixed on the blade 21 of wheel hub 22 circumferential direction; Wheel hub 22 is fixed on the central shaft 31 of centrifugal blower 3.The impeller unit 2 of said structure is convenient to manufacture, install, and can be taken to the parts on existing axial-flow blower.
Blade 21 and wheel hub 22 are directly fixedly connected with various ways, can adopt integral structure, or bolt connection etc.The quantity of blade 21 is preferably at least two panels, and each blade 21 is roughly arranged on wheel hub 22 according to the mode of radial dispersion, and enter the wind of impeller unit 2 under the effect of blade 21, air quantity is increased.
Further, impeller unit 2 also comprises cylindrical shell 23.Cylindrical shell 23 is positioned at the outside of blade 21, and cylindrical shell 23 is fixedly connected with blade 21.Wherein, cylindrical shell 23 is also tightly connected with the shell 32 of centrifugal blower 3.
The mode realizing being tightly connected between the shell 32 of cylindrical shell 23 and centrifugal blower 3 has multiple, as by arranging the modes such as Sealing.
Arranging cylindrical shell 23 can make extraneous air can more effectively be inhaled in impeller unit 2.
In the present embodiment, cylindrical shell 23 is integral type structure with the shell 32 of centrifugal blower 3.Specifically, cylindrical shell 23 is integral type structure towards the shell 32 of one end of centrifugal blower 3 and centrifugal blower 3 away from one end of motor 6.Adopt said structure, the sealing effect of whole extractor fan can be strengthened, and then strengthen the exhausting effect of whole extractor fan.
Further, the motor 6 of centrifugal blower 3 is arranged on spiral case 4 inside of centrifugal blower 3.The output shaft of the motor 6 of centrifugal blower 3 and the central shaft 31 of centrifugal blower 3 are the same axis.Centrifugal blower 3 is coaxial, coaxial with impeller unit 2.
The above-mentioned impeller unit 2 mentioned can use the impeller unit on existing axial-flow blower, to reduce design cost.
The extractor fan 1 that technique scheme provides is introduced in detail below in conjunction with accompanying drawing.
As shown in Figure 1, Figure 2, Figure 3 shows, above-mentioned extractor fan 1 can be made up of jointly the impeller unit 2 on traditional centrifugal blower 3 and traditional axial-flow blower, the extension (i.e. cylindrical shell 23) of impeller unit 2 and the extension (i.e. shell 32) of centrifugal blower 3 belong to the formula structure that is fixed as one, the wheel hub 22 of impeller unit 2 is arranged on the central shaft 31 of centrifugal blower 3, to make impeller unit 2 coaxial, coaxial with centrifugal blower 3.As shown in Figure 4, Figure 5, the central shaft 31 of centrifugal blower 3 is driven by motor 6 and rotates; Motor 6 is fixedly mounted in the spiral case 4 of centrifugal blower 3.
So that above-mentioned extractor fan 1 is used on kitchen ventilator, when kitchen ventilator works, the central shaft 31 of motor 6 with centrifugal blower 3 rotates, because impeller unit 2 and centrifugal blower 3 belong to integrative-structure, when motor 6 drives whole extractor fan 1 to rotate, impeller unit 2 rotates by the mode blade 21 of axial-flow blower, utilizes the advantage of axial-flow blower on Wind Volume, and Wind Volume sucks oil smoke.Centrifugal blower 3 rotates by centrifugal blower mode simultaneously, utilizes principle and the advantage of centrifugal blower 3 on blast of centrifugal blower 3, and pressurizeing to the flue gas of impeller unit 2 suction and complete turns to work.Flue gas flows along spiral case 4, is finally discharged by the safety check 5 on kitchen ventilator.Safety check 5 docks with spiral case 4, and is installed together with whole oil smoke body.
