The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
Referring to Fig. 1~Fig. 3, a kind of range hood, including exhaust fume collecting hood 1, the fan shroud 2 positioned at the top of exhaust fume collecting hood 1, fan shroud
Adjusting means 3 and blower fan 4 are provided with 2.Air inlet 11, adjusting means 3 and the position pair of air inlet 11 are offered on exhaust fume collecting hood 1
Should, and on oil smoke flow path, positioned at the upstream of blower fan 4.
Referring to Fig. 3~Fig. 9, adjusting means 3 includes housing 31, swivel plate 32, the first drive mechanism 33, mobile dish 34, the
Two drive mechanisms 35 and a vane piece 36.Wherein, housing 31 includes side wall 311 and is arranged on the ring wall 312 on the periphery of side wall 311,
Ring wall 312 extends a certain distance towards blower fan 4.Side wall 311 and ring wall 312 constitute a cavity, and ring wall 312 is around side wall
311 both sides and top, bottom missing, i.e. bottom surface opening of the housing 31 towards the air inlet 11 of exhaust fume collecting hood 1；In addition, housing 31
Only one side wall 311, that is, cause the back side (the positive relative side constituted with side wall 311) of housing 31 towards blower fan 4 to open
Mouthful so that oil smoke air-flow can enter in the cavity of housing 31 from bottom, and exit into blower fan 4 from the back side.The top of ring wall 312
There is depressed part 3121 in the position by proximal wall 311, it is possible thereby to reduce runner, play a part of uniform water conservancy diversion.
The dividing plate 313 parallel with side wall 311 is additionally provided with housing 31, dividing plate 313 is provided with blow vent 314.Above-mentioned
Swivel plate 32 is arranged on the lower section of dividing plate 313, and the first drive mechanism 33 includes motor 331, gear 332 and rotating shaft 333, motor
331 can be arranged on the outside of ring wall 312, and gear 332 is engaged with the output shaft of motor 331 (also may be used on such as output shaft of motor 331
To set gear 3311), the two ends of rotating shaft 333 are each passed through the part of ring wall 312 of the both sides of side wall 311 and rotate connection, and
One end of rotating shaft 333 penetrates the center of gear 332, and the upper surface of swivel plate 32 is connected with the side of rotating shaft 333.Thus, electricity is worked as
When machine 331 starts, by gear 332 rotating shaft 333 can be driven to rotate, so that rotating shaft 333 drives 333 turns around the shaft of swivel plate 32
It is dynamic.
Mobile dish 34 are arranged between dividing plate 313 and side wall 311, and can also be parallel with side wall 311.Mobile dish 34
Size, shape and position are corresponding with the blow vent 314 on dividing plate 313, in the present embodiment, and mobile dish 34 and blow vent 314 are equal
It is rounded, and mobile dish 34 are slightly less than blow vent 314.Second drive mechanism 35 includes cylinder 351 and piston 352, wherein, gas
Cylinder 351 is arranged on the outside of side wall 311, and piston 352 is penetrated out of cylinder 351 inside housing 31, is connected with mobile dish 34, so that
The linear reciprocating motion in the horizontal direction of mobile dish 34 is driven, closer or far from blow vent 314.
The both sides that vane piece 36 and mobile dish 34 are located at dividing plate 313 respectively are played, thus, are set in housing 31 positioned at dividing plate 313
The space being equipped between the side of vane piece 36 and backside openings constitutes the first gas channel A, plays vane piece 36 and is located at the first gas
In circulation road A；And the space being located in housing 31 between dividing plate 313 and side wall 311 then constitutes the second gas channel B, mobile dish
34 are located in the second gas channel B, and the blow vent 314 on dividing plate 313 connects the first gas channel A and the second gas channel B.
It can be prewhirled when air-flow is by playing vane piece 36 and then enter back into blower fan 4, the first gas channel A and the second gas are entered by regulation
Circulation road B oil smoke air-flow ratio, so as to control the size of pre- rotational gas flow, realizes the regulating working conditions of range hood.
Play at least part of vane piece 36 to fix with dividing plate 313, such as by way of welding, and extend partially into blow vent
314 corresponding positions.Playing vane piece 36 includes multiple blades 361, is discretely arranged along the periphery of blow vent 314, Mei Geye
Piece 361 is in bending, and air-flow is from the periphery of blade 361 inwardly into being prewhirled so as to be formed, the direction of air-flow is referring to arrow in Fig. 8
It is shown.Because the air-flow of the entrance of air inlet 11 from exhaust fume collecting hood 1 is uneven, for the rotation for the air-flow for avoiding enter into blower fan 4
Around being axially presented greatly uneven, the bending direction of blade 361 for being located at the vertical direction both sides at center is relative, and is located at
The bending direction of blade 361 of vertical direction the same side is consistent, it is preferred that the blade 361 of both sides is in symmetrical.
Because blower fan 4 all goes to be designed according to general work operating mode, when air quantity is excessive, it will rush
Loss is hit, accordingly, it would be desirable to by a speed of prewhirling, eliminate impact component velocity, and then reduces loss, increases efficiency, that is,
Say, when air quantity is bigger, it is desirable to bigger speed of prewhirling, and reduce the flow without pre- rotational gas flow.Swivel plate 32 and level side
To angle be θ, when θ be 0 ° when, swivel plate 32 is by the channel enclosed between dividing plate 313 and the bottom of side wall 311, and oil smoke air-flow is complete
It is complete to enter the first gas channel A, by playing prewhirling for vane piece 36, blower fan 4 is rotated into, big speed of prewhirling is formed
Degree；When the angle, θ of swivel plate 32 increases, now fraction enters from the first gas channel A, and fraction is then from the second gas
Circulation road B enters, and can be moved by the position adjustments of mobile dish 34 towards dividing plate 313 or remote dividing plate 313, so as to adjust
Flow between whole mobile dish 34 and dividing plate 313, that is, adjust from the entrance of the blow vent 314 of dividing plate 313 without pre- rotational gas flow and from
The ratio for the pre- rotational gas flow that vane piece 36 enters, realizes the regulation of operating mode；When the angle, θ that swivel plate 32 rotates reaches 180 °,
First gas channel A is closed, and air-flow all enters (without prewhirling) from the second gas channel B, now can still be moved by adjusting
The position of Moving plate 34, realizes the size that pre- rotational gas flow is controlled with the change of operating mode, realizes the regulating working conditions of range hood.
Referring back to Fig. 2, the air outlet of blower fan 4, which is provided with air-out mouth mask 5, air-out mouth mask 5, is provided with air velocity transducer 6,
Real-time air quantity monitoring is carried out, and air quantity monitoring result is fed back in the control system 7 of range hood, according to the air quantity knot of feedback
Really, the first drive mechanism 33 and the second drive mechanism 35 are controlled, the angle of swivel plate 32 and the position of mobile dish 34 is thus adjusted
Put.
The utility model has the advantage of：(1) tune of lampblack absorber operating mode can be realized by adjusting size of prewhirling in real time
Section, reaches efficiency increase, the effect of energy consumption reduction；(2) inlet air conditions of main air blower can be improved, the flow field point of inside is improved
Cloth；(3) method for realizing regulating working conditions relative to traditional use choke valve, is more saved and effective.
