Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
Embodiment 1, as shown in Fig. 1～Fig. 5, top-sucking kitchen ventilator in the present embodiment includes body 10, exhaust fume collecting hood 100, blower fan 3 and cowling panel 1, exhaust fume collecting hood 100 has air inlet from bottom to top, this air inlet is just being arranged also and is forming the air intake passage passed through for oil smoke between exhaust fume collecting hood 100 internal chamber wall by cowling panel 1, aforesaid body 10 is longitudinally located at exhaust fume collecting hood 100 top, and blower fan 3 is located in body 10, and cowling panel 1 can be located at the air inlet of exhaust fume collecting hood 100 up and down.
Cowling panel 1 is arranged at the air inlet of exhaust fume collecting hood 100 by an elevating mechanism, elevating mechanism includes motor 2, push rod 22 and bracing frame 23, motor 2 is located in body 10 and is had hydraulic cylinder 21, and push rod 22 is longitudinally disposed, and upper end is connected with hydraulic cylinder 22 and can move up and down under the effect of motor 2；Bracing frame 23 bottom surface is connected with the upper surface of cowling panel 1, and top is connected with the lower end of push rod 22.
The rear end of body 10 is located at by blower fan 3, and motor 2 is then arranged at the front end face of Blower Housing 31 by U-bracket.Bracing frame 23 is in X-shaped, and including cross one another first stripe board 24 and the second stripe board 25, push rod is then connected with the infall of the first stripe board 24 and the second stripe board 25.Motor 2 and blower fan 3 one in front and one in back make one to stress side gently in body 10, and by the counterweight that X-shaped bracing frame 23 is suitable, the overall center of gravity that can conveniently realize bracing frame 23 and cowling panel 1 is positioned at the position of centre of gravity of push rod 22.
The air inlet of exhaust fume collecting hood 100 is positioned at cowling panel 1 and is arranged over an oil network 5, the bottom of this oil network 5 is in tilted layout by under forward-backward algorithm, oil network 5 is stretched out and in downward-sloping setting in the rear end of cowling panel 1, accordingly, it is provided with bottom the rear end of exhaust fume collecting hood 100 and can collect the lubricating cup 4 flowing down oil droplet from cowling panel 1, further, push rod 22 extends through this oil network 5.
Exhaust fume collecting hood 100 is provided with the button 101 that energy drive motor starts, it is provided with one bottom the rear end of exhaust fume collecting hood 100 and can open and close the whether in running order light sensor of button (without display in figure), lubricating cup 4 is positioned at the lower section of light sensor, and control chip (without display in figure) is connected with the signal output part of light sensor and the control input of button 101.
As shown in Figure 3, when cowling panel 1 is in a high position, cowling panel 1 presses close to exhaust fume collecting hood 100 internal chamber wall, hides cowling panel 1, cowling panel 1 shape presses close to the shape of whole exhaust fume collecting hood 100 inner chamber more so that user feel cowling panel lower surface and inner chamber time feel integration.
As shown in Figure 4, when cowling panel 1 is in middle position, having predeterminable range between cowling panel 1 and exhaust fume collecting hood 100 internal chamber wall, predeterminable range is preferably 5～9 centimetres, and the present embodiment is 7 centimetres；Operation effectively shortens cowling panel with cigarette spacing from making negative pressuren zone and cigarette spacing from minimizing, strengthens smoking effect, can ensure that favorable user can't see cowling panel inner case simultaneously, maintain the overall appearance of product.
As it is shown in figure 5, when cowling panel 1 is in low level and during maximum height, be 40 centimetres in the present embodiment, cowling panel 1 extends downwardly from exhaust fume collecting hood 100 and exceedes predeterminable range.
Time lubricating cup 4 is loaded onto, light is blocked by lubricating cup 4, and light sensor can't detect the light of lower section, and control chip pre-set control programs makes the button of cleaning to work；After taking off lubricating cup, light sensor detects light, control chip pre-set control programs makes the key works of cleaning, when user pushes button time, push rod external part continues to be moved downwardly to minimum point, drive bracing frame and cowling panel decline maximum height, make user can conveniently clean cowling panel, bracing frame and oil network, maintain the easy to clean of product.
Embodiment 2, as shown in Fig. 6～Figure 11, is provided with the hinge 6 that can regulate height between internal chamber wall and the end face of cowling panel 1 of the exhaust fume collecting hood 100 in the present embodiment.Hinge 6 adopts damp hinge.Hinge 6 is three, is respectively arranged in the front end of cowling panel 1 and both sides.As shown in Figure 8, wherein between pin-joint piece 61, logical overdamped jointed shaft 62 connects.
The air inlet of exhaust fume collecting hood 100 is positioned at cowling panel 1 and is arranged over oil network 5, the bottom of this oil network 5 is in tilted layout by under forward-backward algorithm, oil network 5 is stretched out and in downward-sloping setting in the rear end of cowling panel 1, accordingly, being provided with bottom the rear end of exhaust fume collecting hood 100 and can collect the lubricating cup 4 flowing down oil droplet from cowling panel 1, hinge 6 is positioned at the periphery (as shown in Figure 7) of oil network 5.Other structural reference embodiments 1.
In the present embodiment, cowling panel 1 altitude mixture control manually drives cowling panel 1 to realize.
Embodiment 3, as shown in figure 12, is additionally provided with electric lifting mechanism in the exhaust fume collecting hood 100 in the present embodiment, and this electric lifting mechanism includes lifting motor 71, fixed pulley 72 and hauling rope 73, and lifting motor 71 has clutch end；Fixed pulley 72 is two, is all located at bottom body 10, and hauling rope 73 one end is connected also with the clutch end of lifting motor 71, and the other end is connected with cowling panel 1 by fixed pulley 72.Hauling rope 73 in the present embodiment preferably employs steel wire.
Hinge in the present embodiment is can be undamped hinge.Other structural reference embodiments 2.In the present embodiment, cowling panel 1 altitude mixture control is by driving lifting motor 71 to realize.
