Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
Embodiment one
Referring to FIG. 1 to FIG. 6, a kind of range hood, including exhaust fume collecting hood 1, fan shroud 2 and blower hood 3 is set in fan shroud 2
It is equipped with centrifugal blower, the setting of blower hood 3 is formed with interlayer outside fan shroud 2, and between fan shroud 2 and blower hood 3.For
Convenient for explanation, in the present specification, " upstream " refers to the upstream of oil smoke flow path, and " downstream " refers to the downstream of oil smoke flow path.
Offer air inlet 11 on exhaust fume collecting hood 1,11 lower section of air inlet, i.e. air inlet 11 upstream be provided with for improving suction
The auxiliary device 4 of oil smoke efficiency.Auxiliary device 4 includes exhaust apparatus 41, guide duct 42 and the accessory fan for generating air-flow
43, guide duct 42 is used to air-flow being directed to exhaust apparatus 41 from accessory fan 43, and exhaust apparatus 41 guides guide duct 42
Air-flow sprays.
In the present embodiment, auxiliary device 4 is eddy flow auxiliary device, and exhaust apparatus 41 extends around axis X, to be formed
Annular shape, oil smoke can pass through from the inner radial of annulus.Alternatively, exhaust apparatus 41 or oval ring-type.In this reality
It applies in example, since range hood is top suction type, axis X is to extend in vertical direction.Wherein, the first of exhaust apparatus 41
End (lower end) is located at the upstream of the second end (upper end) of exhaust apparatus 41 and first passes around exhaust apparatus 41 when that is, oil smoke flows
First end is then left from the second end of exhaust apparatus 41.
Exhaust apparatus 41 includes the cricoid lateral wall 411 and cricoid inner sidewall 412 for surrounding axis X extension, wherein in
412 opposite exterior lateral sides wall 411 of side wall is closer to axis X.With it is above correspondingly, lateral wall 411 and inner sidewall 412 first end position
In the upstream of 412 second end of lateral wall 411 and inner sidewall.Pass through first end between lateral wall 411 and the first end of inner sidewall 412
Wall 415 is connected and is closed, and is connected and is closed by the second end wall 416 between lateral wall 411 and the second end of inner sidewall 412, by
This, lateral wall 411, inner sidewall 412, the first end wall 415 and the second end wall 416 form cricoid air storing cavity 413, and oil smoke then may be used
Pass through from the inside of inner sidewall 412.Inner sidewall 412 from first end to second end, be increasingly towards axis X inclination, inner sidewall 412 with
The angle of axis X is α, 0 °≤α≤30 °, oil smoke to be downstream inducted into the air inlet 11 of exhaust fume collecting hood 1.Exhaust apparatus
41 height (with axis X on parallel direction at a distance from) is h, 20mm≤h≤350mm, promotes fume-exhausting effect to both meet
The requirement of rate, and the beauty of range hood is not influenced.
Air outlet 414 is formed on inner sidewall 412, air outlet 414 extends along axis X, and with above-mentioned air storing cavity
413 connections.In the present embodiment, air outlet 414 is formed by following modes: inner sidewall 412 includes the partition of multiple arcs
4121, above-mentioned multiple partitions 4121 are circumferentially arranged (around the direction of axis X), to constitute cricoid inner sidewall 412.Often
First end in a 4121 circumferential direction of partition is radially-inwardly bent (towards axis X direction), so that each partition 4121 is circumferential
On 4121 circumferential direction of second end and adjacent separator on first end between limit above-mentioned air outlet 414, i.e. two partitions
Air outlet 414 is limited between the apparent surface of 4121 adjacent end portions.The circumferential direction of above-mentioned air outlet 414 and inner sidewall 412 as a result,
Shape has a certain degree, and each air outlet 414 is identical as the angle that inner sidewall 412 is circumferentially formed.Multiple air outlets 414 as a result,
The air-flow of blowout forms the flow field (eddy flow) of rotation with circumferential component.The air gas blown out referring to Fig. 3, accessory fan 43
Stream is with shown in filled arrows, oil smoke air-flow is shown in hollow arrow.
Air outlet 414 can also be distributed with equidistantly distributed with unequal spacing.Air outlet 414 has outlet 4143, outlet
4143 be the end of air outlet 414, and air-flow leaves the position before air outlet 414.The opening width d of air outlet 414, that is, exporting

Exhaust fume collecting hood 1 passes through, the interlayer being upwardly between fan shroud 2 and blower hood 3 and be connected to the air outlet of accessory fan 43, this
Kind set-up mode can also avoid influence of the oil smoke to accessory fan 43.Referring to Fig. 7, air storing cavity 413 is in the company with guide duct 42
When logical place extends to the direction far from guide duct 42, sectional area is gradually increased, and sprays air-flow to can guarantee from air outlet 414
Uniformity.By the setting of guide duct 42, the air-flow that accessory fan 43 is blown out can be directed in air storing cavity 413, Jin Ertong
Air outlet 414 is crossed to spray and form eddy flow.The eddy flow cuts the oil smoke air-flow offer entered from the channel among exhaust apparatus 41
Xiang Li generates spout effect in the case where the centrifugal blower (main air blower) in fan shroud 2 is drawn up the collective effect of power, to draw in
It at a distance from range pot face, improves cigarette tobacco control and anti-interference ability, inherently solves top-sucking kitchen ventilator fume-exhausting energy
The bad problem of power.
Exhaust apparatus 41 is also possible to lower when work, store upwards when not working either suspension is fixed, from
And the overall appearance of range hood is neither influenced, and the effect for extending and promoting fume-exhausting can be expanded downwards by negative pressuren zone.For
Convenient for the lifting of exhaust apparatus 41, it is additionally provided with lifting device 5, lifting device 5 includes the electricity that the outer left and right sides of fan shroud 2 is arranged in
Dynamic push rod 51 and the transmission bracket 52 being connected between auxiliary device 4 and the end of electric pushrod 51, in the present embodiment,
Electric pushrod 51 extends downwardly, and transmission bracket 52 is connected to the top of guide duct 42.As a result, when electric pushrod 51 is released downwards
When, one end that transmission bracket 52 is connect with guide duct 42 ramps up, so that exhaust apparatus 41 be driven to move upwards；Work as electric pushrod
When 51 upward gathering, one end that transmission bracket 52 is connect with guide duct 42 is to decline, so that exhaust apparatus 41 be driven to move downward.
Lifting device 5 can automatically control work according to the amount of oil smoke, and the range that driving auxiliary device 4 is gone up and down is 100~300mm.
