Description
Technical field
The present invention relates to a kind of range hood, more particularly, to a kind of near-suction type oil smoke suction machine.
Background technology
Existing near-suction type oil smoke suction machine typically all includes blower hood and the casing being connected to below blower hood, blower fan
Blower fan system is installed, the front of casing is formed with the air inlet of strip in outer cover, also, due to being located at using fans entrance
The straight suction form at casing center, therefore negative pressure concentrates on the central area of casing, causes the intake velocity of strip air inlet not
Uniformly, middle intake is big, left and right sides intake is small, and the control ability to left and right sides oil smoke is weaker, and air inlet or so
Both sides are just the regions of oil smoke concentration ascension, so that smoke absorption effect is not good just to stove eye.Further, since blower fan enters
Mouth faces user, and when range hood works, the noise of generation is relatively large.
Additionally, the entire length of near-suction type oil smoke suction machine is typically greater than the length of kitchen range, when range hood works, leave
Negative pressure reduces immediately after the segment distance of air inlet one.In view of general user family all use Double gas cooker kitchen range, when two pans simultaneously
When using, such as side cooking and opposite side is cooked, cooking side produce oil smoke it is more, side of cooking is nearly free from oil
Cigarette, and existing near-suction type oil smoke suction machine does not enter oil smoke due to that cannot adjust left and right negative pressure distribution, thus occur that cooking side is inhaled
And the phenomenon that side negative pressure of cooking is wasted.
The content of the invention
First technical problem to be solved by this invention is directed to above-mentioned state of the art, there is provided one kind can be to air intake
Implication stream carries out the near-suction type oil smoke suction machine of rectification.
Second technical problem to be solved by this invention is directed to above-mentioned state of the art, there is provided one kind can be according to cigarette
The mist size near-suction type oil smoke suction machine good to adjust the intake and smoke absorption effect of corresponding side.
The present invention solve technical scheme that above-mentioned first technical problem used for：The near-suction type oil smoke suction machine, including
Blower hood, casing and blower fan system, the casing are located in blower hood located at blower hood lower section, the blower fan system,
The inlet side of the casing is provided with air inlet, and the length direction of air inlet is consistent with casing left and right directions, it is characterised in that：
The air inlet is provided with guide vane, and the guide vane be spaced apart successively from left to right and formed air inlet every
Grid.
The present invention solve technical scheme that above-mentioned second technical problem used for：The near-suction type oil smoke suction machine, is located at
The guide vane of air inlet zone line is the fixed guide vane fixed towards angle, positioned at the water conservancy diversion of the air inlet left and right sides
Blade according to the smog size of respective side to adjust the movable guide vane of open angle.
In order to reduce the noise that direct transfers of blower fan, it is preferable that positioned at the court of the fixed guide vane of the center-left side of air inlet
To angle to deflect to the left from top to bottom, positioned at the center-right side of air inlet fixed guide vane towards angle be from upper
And under deflect to the right.
The fixed open angle of fixed guide vane can have certain limit, further preferably, the fixed guide vane
Deflection angle be~55 ° of angle at 45 ° with planar shaped where the air inlet end.
Further preferably, the projection of the fans entrance of blower fan system plane where the air inlet end is located at solid
Determine in the region corresponding to guide vane.
In order that the movable guide vane of the left and right sides is preferably engaged with the left and right stove eye of gas-cooker, positioned at air inlet
The movable guide vane in left side deflects setting in the same direction with the fixed guide vane of center-left side, the activity on the right side of air inlet
Guide vane deflects setting in the same direction with the fixed guide vane of center-right side.
The open angle of movable guide vane can have various adjustable ranges, it is preferable that the movable guide vane is beaten
The adjustable range of angle of release degree is the angle with 20 °~75 ° of plane formation where the air inlet end.
In order that the runner between guide vane has rectified action, the fixed guide vane and movable guide vane are equal
It is wave blade.
In order that guide vane can optimize the wake flow hauled out backward, the fixed guide vane is interior with movable guide vane
Side is in inside and outside concavo-convex wave structure.So, after guide vane afterbody optimizes, noise reduction can be played.
Compared with prior art, the advantage of the invention is that：The near-suction type oil smoke suction machine is located at the guide vane of air inlet
Be spaced apart successively from left to right and form the barrier of air inlet, wherein positioned at air inlet zone line guide vane to fix
Guide vane, guide vane positioned at the air inlet left and right sides according to the smog size of respective side to adjust open angle
Movable guide vane, makes intake be adapted with smog size, so as to adjust the negative pressure distribution of air inlet, makes air intake air-flow more
Uniformly, smoke absorption effect is more preferable.
