Abstract

The invention discloses a rang hood with a guide plate capable of automatically opening and closing, comprising an upper cover, an oil fume collecting chamber, an electrical control case, a key and a front panel. The front panel is provided with a movable guide plate capable of opening and closing, and the top of the movable guide plate is provided with a transmission device for controlling the oil fume absorbing opening of the oil fume collecting chamber to open and close. Instructs are sent through a key on the front panel, the electrical control case controls the transmission device to rotate, and the transmission device rotates forwards and reversely to control the movable guide plate on the front panel to open and close the oil fume absorbing opening of the oil fume collecting chamber. Therefore, the oil fume absorbing opening is opened when the range hood works, and the oil fume absorbing opening is closed when the range hood stops working.

Description

The lampblack absorber of the self controllable folding of a kind of deflector

[technical field]

[background technology]

In order to improve ventilation condition in the kitchen, discharge the oil smoke and the waste gas that produce in the cooking process, the electrical appliance that smoke exhaust ventilator has become each family's indispensability is installed in the kitchen, but, generally adopt fixedly connected between the panel of present smoke exhaust ventilator and the case, not only take the inner space in kitchen, and the smoking port of lampblack absorber is in open mode always, particularly at the floor of common exhaust duct, cause the backflow of air in the pipeline easily and recharge, pollute the air in the kitchen once more, influence the air quality of inside, kitchen.

[summary of the invention]

Advantage of the present invention provides a kind of simple in structure, control convenience, takies the lampblack absorber of the little self controllable folding of deflector of kitchen area.

The technical solution adopted for the present invention to solve the technical problems is:

The lampblack absorber of the self controllable folding of a kind of deflector comprises loam cake, smoke collecting chamber, electric-controlled box, button and front panel, but front panel is provided with the movable deflector of folding, the top of described movable deflector is provided with the transmission device of the smoking port folding of control smoke collecting chamber, the rotation of electric-controlled box control transmission device;

The lampblack absorber of the self controllable folding of aforesaid a kind of deflector, described transmission device is a screw actuator, this device comprises the rotating motor that is fixed on the movable deflector, with coaxial drive screw that is connected of rotating motor and the nut that is fixed on smoke collecting chamber inwall or front panel inboard, be provided with the nut support of hold-down nut in nut and smoke collecting chamber inwall or front panel inboard, on the nut support, be provided with travel switch, between rotating motor and movable deflector, be provided with the fixedly motor bracket of rotating motor, be provided with the contact that contacts with travel switch in motor bracket one side, be provided with the hinge of support activity deflector folding in movable deflector bottom;

The lampblack absorber of the self controllable folding of aforesaid a kind of deflector, described front panel and movable deflector are face glass;

The lampblack absorber of the self controllable folding of aforesaid a kind of deflector, described travel switch comprise deflector opening travel switch and deflector shutoff stroke switch.

The invention has the beneficial effects as follows:

The smoking port setting of smoke collecting chamber of the present invention is the face glass of folding automatically, relatively before fixed smoking port, but the lampblack absorber smoking port of folding, the one, can save the solid space of lampblack absorber, increase the kitchen effective area; The 2nd, the folding automatically of the face glass of smoking port, the culinary art food is intact both can close smoking port automatically, avoided the backflow of air, influenced the air quality in kitchen.

[specific embodiment]

The lampblack absorber of the self controllable folding of a kind of deflector, as depicted in figs. 1 and 2, comprise loam cake 1, smoke collecting chamber 2, electric-controlled box 3, button 4 and front panel 5, but plate 5 is provided with the movable deflector 6 of folding in front, the top of described movable deflector 6 is provided with the transmission device 7 of smoking port 20 foldings of control smoke collecting chamber 2, sends instruction by the button on the front panel 54, the rotation of electric-controlled box 3 control transmission devices 7, transmission device 7 is by rotating and reverse, movable deflector 6 on the control front panel 5 opens and closes the smoking port 20 of smoke collecting chamber 2, opens smoking port 20 when realizing smoke exhaust ventilator work, closes smoking port 20 when quitting work.

As shown in Figures 2 and 3, described transmission device 7 is a screw actuator, this device comprises the rotating motor 70 that is fixed on the movable deflector, with coaxial drive screw that is connected 71 of rotating motor and the nut 72 that is fixed on front panel 5 inboards, described nut 72 is fixed on smoke collecting chamber 2 inwalls or front panel 5 inboards by nut support 73, on nut support 73, be provided with travel switch 74, rotating motor 70 is fixed on the movable deflector 6 by motor bracket 75, be provided with the contact 76 that contacts with travel switch 74 in motor bracket 75 1 sides, be provided with the hinge 8 of support activity deflector 6 foldings in movable deflector 6 bottoms.

Described front panel 5 and movable deflector 6 are face glass, during use, power-on, by the suction inlet key 40 on the front panel 5, behind electric-controlled box 3, start at the uniform velocity counter-rotating of rotating motor 70, drive drive screw 71 counter-rotatings, at nut 72, nut support 73 and under the hinge 8 of movable deflector 6 bottoms supports, motor bracket 75 promotion activity deflectors 6 outwards move, when smoking port 20 opens to extreme position, contact 76 on the motor bracket 75 touches deflector opening travel switch 740, and rotating motor 70 stops counter-rotating, 20 one-tenth open modes of smoking port, open the blower fan in the smoke collecting chamber, carry out smoking work.

After culinary art finishes, close blower fan, press the suction inlet key 40 on the front panel 5, starting rotating motor 70 is at the uniform velocity just changeing, under the hinge 8 of nut 72, nut support 73 and movable deflector 6 bottoms supports, the movable deflector 6 of motor bracket 75 pulling glass moves inward, when smoking port 20 closed to extreme position, the contact 76 on the motor bracket 75 touched deflector shutoff stroke switch 741, and rotating motor 70 stops just to change, powered-down is promptly finished the automatic folding of smoke exhaust ventilator panel then.
