Description
Technical field
Range hood field is the utility model is related to, especially a kind of side-suction type fume-exhausting with electric pushrod mechanism
Machine.
Background technology
Existing side-suction type range hood, shell, the blower fan system being arranged in shell, and controlling switch are generally included,
Shell includes the side plate of both sides and the panel positioned at face kitchen range top side, panel are provided with inlet scoop, connect blower fan system
After power supply, row arrives common flue after oil smoke is sucked blower fan system by inlet scoop.It is inconvenient when this lampblack absorber cleaning, except clear
Wash outside shell, it is also necessary to the fan blade or the filter positioned at inlet scoop for the blower fan system extending into inlet scoop cleaning shell.
Therefore, improving on this basis, such as the Chinese patent of Application No. 201020026644.5, one is disclosed
Smoke exhaust ventilator of the kind with retractable shield door, including shell, blower fan and controlling switch, the side of shell towards oil smoke are provided with
Hole, size and the shield door in the hole match, and driving shield door is additionally provided between shield door and shell and is transported along the axial direction in the hole of shell
Dynamic electric driver.When not in use, shield door maintains an equal level with shell towards oil smoke side side, when switching on power, electric driver
Drive shield door axially inwards or be displaced outwardly, make to leave gap, oil smoke between shield door and the edge in the hole on shell side
Outdoor is then exhausted from after the gap is sucked by blower fan, shield door can reset after use.
More health but maintenance inconvenience, and can not stop that oil smoke dissipates to surrounding, absorb oil when this lampblack absorber uses
Cigarette effect is bad, user on the face, with it, hair can be perplexed by oil smoke, cause inconvenient for use.Thus, grind now
A kind of openable side-sucking oil smoke sucking machine of baffle plate as disclosed in Application No. 201310379655.X Chinese patent is made, in collection cigarette
Two turning joints are housed between cover front bevel biside plate top and overhead gage；Lower baffle plate is fixed under exhaust fume collecting hood front bevel
Portion, is equipped with electric device between exhaust fume collecting hood and turning joint, and electric device includes electric pushrod and connecting rod or electric device
Including electric pushrod and support bar；And for example a kind of electric pushrod drives disclosed in the Chinese patent of Application No. 201310435447.7
Dynamic double turnover panel range hoods, including frame, the side of frame offer the air inlet being obliquely installed.By fume-exhausting on air inlet
Panel assembly is covered, and fume-exhausting panel assembly includes keeping out the wind panel, fairing panel and lower panel, close to air inlet in frame
Side is additionally provided with electric pushrod, and the outer casing member of electric pushrod is hinged in frame, and the bottom of fairing panel medial surface is set
There is a connecting seat, expansion link and the connecting seat of electric pushrod are hinged, and the bottom for the panel medial surface that keeps out the wind is hinged with a connecting rod, even
The end of bar is hinged on the end of the outer casing member of electric pushrod；And for example the Chinese patent of Application No. 201420568915.8 is public
A kind of cigarette machine for the automatic open-close smoke barrier opened, including smoke barrier and push-rod electric machine, smoke barrier are arranged at mouth, on smoke barrier
Portion is fixedly connected with to be connected in the chute coordinated, one end of driving lever is rolled with rotor block by hinge with smoke barrier, main
The other end of lever is connected by hinge with the output end for the push-rod electric machine for installing limit switches, the centre position of driving lever
By rotating fulcrum on cigarette machine body；The other end of push-rod electric machine is connected by hinge with cigarette machine body so that is pushed away
Bar motor can be for linear motion, can also rotate.
The lampblack absorber of above-mentioned several band smoke barriers (baffle plate), smoke barrier can not be opened when oil smoke is few；When needing to use
During smoke barrier, smoke barrier is driven to open or close by electric pushrod.But this several lampblack absorber, the electric pushrod generally used
Mounting means be to be respectively provided with joint in the push rod end of electric pushrod, push rod outer casing end, axis hole is offered on joint, lead to
Cross the axle inserted into axis hole to be connected with the casing of smoke barrier or range hood, pin is plugged on axle or nutting is fixed.Above-mentioned peace
Dress mode has the disadvantage that：1st, range hood is for a long time in the environment of oil smoke, and common axle, hole connect, the gap in axle and hole
Greatly, easily dirty in junction long-pending oil, so as to increase mutual frictional force, long-term use can reduce the service life of push rod；
2nd, existing gap between axle and hole, can cause when smoke barrier moves in smoke barrier stress deflecting because of gap and caused by smoke barrier
Pause and jitter phenomenon during folding；3rd, casing of cooking fume exhaustor is sheet metal component, and its assembly technology is substantially manual on streamline
Assembling, assembling procedure length, precision is low, because push rod rigging error can caused by push rod and push rod shell there is certain angle, figure
Shown in 12, shape is at a certain angle between the axis X of push rod and its thrust F1 being subject to so that push rod by radial load F2 and
Cause to bend, influence the operational efficiency and service life of push rod, while cause to accelerate worm and gear accelerated wear test.
Utility model content
