Embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment one
As shown in Figure 1, a kind of Dropbox of kitchen ventilator, including, outer wheel hub 1, spider 2, connect outer wheel hub 1 and spider 2
Skeleton 3, and the twine 4 being arranged between outer wheel hub 1 and spider 2.The spider 2 is equipped with mounting structure (in figure
It is not shown), and be connected with the output shaft of motor or impeller, motor driving Dropbox or motor driven impeller drive Dropbox to turn at a high speed
Dynamic, when Dropbox rotates, twine 4 collides with the oil droplet in air, plays the role of intercepting oil droplet.Preferably, the net
Silk 4 is the more one metal wires being radially distributed along the radial direction of spider 2, and when twine 4 and droplets contact, oil droplet will first be inhaled
It is attached on twine 4, is then thrown out of under the action of the centrifugal force, is discharged into oil collection box.
Intensity and the bonding strength of outer wheel hub 1 and spider 2 of the skeleton 3 for strengthening overall Dropbox, the one of skeleton 3
End is connected with outer wheel hub 1, and the other end is connected with spider 2, is preferably integrally formed, or three's connection mode is weldering
Connect or rivet.The skeleton 3 has the windward side of area change, and the direction that its front face area increases along air quantity gradually becomes
It is small, so that for skeleton 3 in air quantity larger part, windage is smaller, reduces its overall air resistance coefficient.
Due to the characteristic of range hood fan, air volume adjustment situation is, smaller close to wind turbine center air quantity, edge air quantity compared with
Greatly, therefore, the front face area of the skeleton 3 is configured to taper into along spider 2 to 1 direction of outer wheel hub.
Specifically, the skeleton 3 is strip, which is provided with an air-permeating hole 33, and the air-permeating hole 33 is along skeleton 3
Length direction extends, and the opening width of air-permeating hole 33 gradually increases along spider 2 to 1 direction of outer wheel hub.The air-permeating hole
33 along spider 2 axially through skeleton 3, enable air to directly pass through skeleton 3, the width of air-permeating hole 33 by air-permeating hole 33
Allow the air-flow that passes through more in the bigger unit length of degree, windage is smaller.
Preferably, the air-permeating hole 33 is projected as triangle or trapezoidal along the axial direction of spider 2.
Preferably, to ensure the bonding strength of skeleton 3, the contact area of the skeleton 3 and outer wheel hub 1 is not less than skeleton 3
With 1/3rd of 2 contact area of spider.
Since Dropbox is installed on the front end of impeller, and directly or indirectly driven by motor output shaft, therefore, air-flow is in impeller
Along the Dropbox that axially penetrates through of Dropbox under effect, the small oil droplet in air-flow can be contacted with the twine 4 in Dropbox, and be intercepted, bone
The air-permeating hole 33 set on frame 3 can allow air-flow to pass through, and then reduce windage, and reduce noise when Dropbox rotates, and reach
More preferable using effect.
Embodiment two
As shown in Fig. 2, the Dropbox of the present embodiment and embodiment one difference lies in 33 structure of air-permeating hole on skeleton 3 not
Together, the air-permeating hole 33 that the skeleton 3 of the present embodiment is equipped with is multiple, length direction of multiple air-permeating holes 33 along skeleton 3
Arrange successively, and the width of different air-permeating holes 33 gradually increases along spider 2 to 1 direction of outer wheel hub so that closer to foreign steamer
Allow the air-flow that passes through more in the air-permeating hole unit length in 1 direction of hub.
The air-permeating hole 33 is any of square hole, bar hole, round hole or slotted eye, it is preferred that described
Air holes is square hole.
Embodiment three
As shown in figure 3, the skeleton 3 of the present embodiment eliminates the setting of air-permeating hole, the skeleton 3 of the present embodiment be along
The strip that spider 2 is gradually narrowed to 1 direction of outer wheel hub so that skeleton 3 tapers into windward side when close to outer wheel hub 1.
Specifically, one end that the skeleton 3 is connected with spider 2 is first end 31, and the skeleton 3 connects with outer wheel hub 1
The one end connect is the second end 32, and the cross-sectional area of first end 31 is more than the cross-sectional area of the second end 32.
A kind of kitchen ventilator for being provided with the Dropbox described in any of the above-described embodiment, the Dropbox are installed on the leaf of kitchen ventilator
The front end of wheel, the impeller are installed on the output shaft of motor, and the Dropbox and impeller are driven by motor and rotated.
The above is the embodiment of the utility model, it is noted that for the ordinary skill in the art,
Under the premise of the utility model principle is not departed from, various deformation and improvement can also be made, this should also be considered as the utility model
Protection domain.
