Description
Technical field
The present invention relates to a kind of range hood, more particularly, to a kind of movable part elevating mechanism of range hood and application
There is the range hood of the elevating mechanism.
Background technology
At present, in order to improve the smoke absorption effect of range hood, people have invented the various oil suctions with movable smoke deflector
Cigarette machine, when range hood works, smoke deflector is driven to carry out elevating movement or yaw motion by drive mechanism, and then adjust and inhale
The air inlet angle and intake of lampblack absorber.Such as Patent No. 201620042811.2 (Authorization Notice No. CN205372692U)
Chinese utility model patent disclosed in《European type cooker hood with automatic smoke deflector》, the range hood include smoke deflector and
Fixed plate, fixed plate side are provided with fixed guide rail, and motion guide rail with matching is provided with fixed guide rail, is set by fixed guide rail
There is drive link, the drive link offsets with motion guide rail, and fixed plate opposite side is provided with motor, and motor is connected with drive link, and motion is led
Rail lower end is provided with fixed support, and fixed support offsets with smoke deflector, and drive link is provided with connecting rod, and connecting rod is placed on motion guide rail,
By motor driven drive link and connecting rod, so that motion guide rail moves up and down on fixed guide rail, to control smoke deflector
Move up and down.Although the range hood is used for driving the structure of the drive mechanism of smoke deflector up and down motion relatively simple and set
Relatively reasonable, still, the smoke deflector drive mechanism of the range hood does not account for the pollution of oil smoke surroundings, permanent to use yet
Afterwards, easily it is stained with greasy dirt on each component of the drive mechanism so that the friction of motion increase between each component, and then lead
Smoke deflector is caused to be difficult to be smoothed out elevating movement, meanwhile, it can also reduce the service life of drive mechanism.Further, since in kitchen
There is the presence of oil smoke, other need the equipment for using sliding bar, such as steam box, the baking box of the flexible panel of drawer type sterilizing cabinet, band
Deng the problem of similar being all present.
The and for example Chinese invention patent Shen of Application No. 201610029797.7 (application publication number is CN 105423395A)
Please be disclosed《European type cooker hood with automatic smoke deflector》, the range hood includes smoke deflector and fixed plate, fixed plate one

Bar offsets with the motion guide rail, and fixed plate opposite side is provided with motor, and the motor is connected with drive link, and motion guide rail lower end is provided with
Fixed support, the fixed support are offseted with smoke deflector, and drive link is provided with connecting rod, and the connecting rod is placed on motion guide rail, passes through electricity
Machine drives drive link and connecting rod, so that motion guide rail moves up and down on fixed guide rail, to control smoke deflector to transport up and down
It is dynamic.The range hood smoke deflector elevating mechanism causes smoke deflector to run not steady enough, smoke deflector due to there was only a motion guide rail
Accurate guiding can not be realized when mobile.
The elevating mechanism of existing range hood generally relies on lifting support and carries out left and right synchronously, and synchronism is poor, lifting branch
Easily rocked in frame lifting process, easily cause lifting support one side and down move more and down move less on one side in addition, cause
Noise and inordinate wear are produced when elevating mechanism works, or even stuck phenomenon be present, in addition, when lifting support itself is inclined
When, also easily cause mechanism to produce bite.As can be seen here, not only cost is higher for existing elevating mechanism, and reliability is low,
Consumer's Experience is poor.
