Description
Technical field
The present invention relates to field of domestic appliances manufacture technology, particularly relate to a kind of range hood and panel automatic open-close method of panel automatic open-close.
Background technology
It is not completely closed that traditional range hood descends air inlet in off position, this air inlet makes extraneous common flue or other space be communicated with indoor, will cause like this under the state of closing at range hood, oil smoke taste in common flue and the oil smoke taste of lampblack absorber itself are diffused into indoor, pollute room air.
Summary of the invention
Based on this, the object of the invention is to overcome the defect of prior art, a kind of range hood of panel automatic open-close is provided, the panel of this range hood can open and close automatically, and under the state of closing at range hood, avoids oil smoke taste to be diffused into the interior space.
For achieving the above object, the present invention takes following technical scheme:
A range hood for panel automatic open-close, comprises casing, blower fan, and described assembling is in casing top, and described lower box is provided with the smoke collecting chamber of tool air inlet; Also comprise panel and be fixed on the panel driving mechanism on casing, described panel driving mechanism comprises motor, gear shaft and tooth bar, described motor-driven gear axle rotation, described tooth bar and the engagement of this gear shaft, and this tooth bar connects panel, described panel has first mode bit of closing described air inlet and the second mode bit of opening described air inlet.
Range hood of the present invention, adopts panel driving mechanism to drive panel rotation, when range hood is closed, makes panel in the first mode bit, closes air inlet, avoids the diffusion of oil smoke taste; And when range hood duty, make panel rotation to the second mode bit, and open air inlet, guarantee the exhausting effect of range hood.And for make panel can be steadily when rotarily opening, closing, operation reliably, the present invention has adopted tooth bar to promote panel, for panel provides support, owing to thering is the feature of stable connection between rack and pinion axle, can only adopt tooth bar to connect panel, without re-using other bindiny mechanism, panel and casing are fixed, both attractive in appearance, avoided again the noise that other bindiny mechanism may cause or the problem of rocking.
In an embodiment, described tooth bar is circular arc therein, drives described panel to take this panel one lateral edges as rotating shaft rotation.The design of arc-shaped rack, the radian while considering panel rotation, when tooth bar connects panel, without using rotating shaft or adopting hinged mode, just can make panel reach the object of rotation, avoids producing and rocks and noise.
Therein in an embodiment, to take the upper edge of this panel be rotating shaft rotation to panel described in described rack drives.The upper edge of panel of take is rotating shaft, and in the time of can making panel rotarily open air inlet, Open Side Down for air inlet, and the cooking stove position producing over against oil smoke, has good exhausting effect.
In an embodiment, described tooth bar is at least two therein, all with described gear shaft engagement.While adopting many tooth bars, asynchronous if move, may make panel rotation produce fault, by many tooth bars are all meshed with gear shaft, each tooth bar can be linked on the one hand, the synchronism that has guaranteed each tooth bar motion, only needs a motor-driven gear axle to rotate on the other hand, just can drive each tooth bar to move simultaneously.
In an embodiment, described tooth bar is two, lays respectively at the two ends of gear shaft therein.Article two, the design of tooth bar, both, for panel provides two strong points, guaranteed panel traveling comfort, had advantages of again simple for structure.
In an embodiment, described two tooth bars connect respectively the two edges that described panel is relative therein.From the relative two edges support panel of panel, can reach more firm, reliable object.
In an embodiment, be also provided with the connecting portion extending along panel plane on described tooth bar therein, described tooth bar is connected with panel by this connecting portion.Above-mentioned setting makes to connect more firm.
The present invention also provides a kind of panel automatic open-close method, adopt above-mentioned range hood, with motor-driven gear axle, rotate, drive the rack synchronous motion with this gear shaft engagement, thereby promotion panel, make panel motion, from the first mode bit/the second mode bit, move to the second mode bit/the first mode bit.
Panel automatic open-close method of the present invention, utilizes gear shaft, and the motion of band carry-over bar promotes panel by tooth bar and moves with this panel, and without re-using other bindiny mechanism, panel and casing fixed, stable while making panel operation, noiselessness, and running status is good.
In an embodiment, described tooth bar is circular arc therein, promotes panel and take this panel one lateral edges and rotatablely move as rotating shaft.Panel is opening and closing in rotary manner, have the feature of profile grace.
Compared with prior art, the present invention has following beneficial effect:
The range hood of panel automatic open-close of the present invention, has the panel that can open and close automatically, and avoids under range hood closed condition, and oil smoke taste is diffused into the interior space.And by the setting of rack and pinion axle, both steady while making panel operation, noiselessness, has guaranteed that the running status of panel is good again.
Panel automatic open-close method of the present invention, utilize the design of gear shaft, the motion of band carry-over bar, by tooth bar, promoting panel rotates around this panel one lateral edges, and without re-using other bindiny mechanism, panel and casing are fixed, stable while making panel operation, noiselessness, running status is good, has improved the reliability of product.
