Description

The gravity flow fume exhaust fan

The utility model relates to a kind of ventilation fan, and particularly a kind of suitable kitchen is especially hung the kitchen and made the ventilation fan that mist extractor uses.

At present, people mostly adopt ventilation fan or smoke exhaust to get rid of oil smoke in the kitchen.The ventilation fan back side is owing to be provided with venetian blinds, thereby in use for some time, tobacco tar just sticks on the venetian blinds, and its weak point one is that venetian blinds is opened difficulty, when serious even can not open; The 2nd, tobacco tar drips along shutter and cover, to seriously polluted inside and outside the window; The 3rd, need be often shutter etc. be pulled down cleaning, trouble, also difficulty.The weak point one of smoke exhaust ventilator is the cost height: the 2nd, clean difficulty; The 3rd, mist extractor effect (particularly in hanging the kitchen) is obviously good not as ventilation fan.

The purpose of this utility model is exactly to provide a kind of unlatching easily, accurately at above-mentioned weak point, and automatic smoke exhausting oil does not pollute window, easy cleaning, the gravity flow fume exhaust fan that mist extractor is effective.

Technical solution of the present utility model is: a kind of gravity flow fume exhaust fan comprises that motor, flabellum and motor support, and is characterized in that: also comprise a downward-sloping cylindrical shell that is connected of fixed panel that is provided with its front end.The rear end of this cylindrical shell is provided with the control device of a drop in leaf and these turnover panel opening and closing of control.Motor is supported and fixed in the cylindrical shell by motor.

Control device described in the utility model technical solution can be by being fixed on control agent on the turnover panel, being connected that turnover panel is connected and passes the nylon rope of panel Shanghai Automobile Factory eye with control agent respectively with spring, two ends between the cylindrical shell with adjustable plate, the fixed screw that is arranged on the panel constitutes, and this adjustable plate is provided with the adjustment hole corresponding with fixed screw.

Drop in leaf described in the utility model technical solution can be circular drop in leaf, and turning cylinder is arranged on the trans D.

Drop in leaf described in the utility model technical solution can also be semicircle drop in leaf, the other fixed head that is connected with cylindrical shell that is provided with of this turnover panel.

The turning cylinder of the semicircle drop in leaf described in the utility model technical solution can be horizontally disposed.

The turning cylinder of the semicircle drop in leaf described in the utility model technical solution can also be 45 setting with horizontal direction.

The utility model is owing to will be downward-sloping design between cylindrical shell and the panel, when panel being fixed on the kitchen or hang on the window in kitchen, cylindrical shell is downward-sloping naturally, the tobacco tar that solidifies just flows out along cylinder inboard wall automatically outward, in addition, the length of general cylindrical shell is much larger than the thickness of ventilation fan, and then the plume of Liu Chuing can be to not polluting inside and outside the window.Because drop in leaf and its control device are adopted in the rear end of cylindrical shell, thereby, also have unlatching, close easy, characteristic of accurate, even the long period cleans except that having the pump drainage of unlatching oil smoke, closing the effect of isolating inner air and outer air, because the effect of spring also opens and closes normal in the same old way.Because barrel front end is not provided with face shield, therefore, during cleaning flabellum is taken off, and just can directly clean flabellum and cylinder inboard wall, and is very convenient.Because adjustable plate is provided with a plurality of adjustment holes, thereby the adjustable angle of drop in leaf upset.Because the rotating shaft of semicircle drop in leaf can be to be the 45 setting with horizontal direction, thereby this fume exhaust fan is fit to be loaded on the side of hanging the kitchen and uses, and air-out is smooth, also can avoid tobacco tar to pollute outdoor metope.Compared with prior art, the utlity model has simple in structurely, it is convenient to clean, processing ease, mist extractor good effectiveness.

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:

Embodiment 1 as shown in Figure 1 and Figure 2.Motor 1 supports 10 through motor and is fixed in the cylindrical shell 3.Fixedly connected between cylindrical shell 3 and the panel 4, and cylindrical shell 3 is downward-sloping design.Turnover panel 13 is circular drop in leaf, and control agent 14 is fixed on the turnover panel 13, and is fixed on the cylindrical shell 3 as the rotating shaft of turnover panel 13, and rotating shaft is the trans D setting.Spring 12 is connected between turnover panel 13 and the cylindrical shell 3.Limited screw 15 is fixed on the top of cylindrical shell 3 rear ends, and restriction turnover panel 13 outwards stirs from top.Nylon rope 7 passes from the vapour eye 5 on the panel 4, and an end is connected with control agent 14, and the other end is connected with adjustable plate 8.Fixed screw 9 is arranged on the panel 4.Adjustable plate 8 is provided with a plurality of adjustment holes.Electric capacity 11 is fixed on and supports on 10.Control agent 14, spring 12, nylon rope 7, adjustable plate 8, fixed screw 9 constitute control device.When opening, pulling adjustable plate 8 is opened by the convergent force that nylon rope 7 makes turnover panel 13 overcome spring 12, and the adjustment hole on the adjustable plate 8 is enclosed within on the fixed screw 9, makes it to remain on reliably on the required angle.When closing, only need to get final product breaking away from adjustable plate 8 people's fixed screws 9, turnover panel 13 and control agent 14 will restPose under the effect of spring 12, closely lean against on the limited screw 15, indoor-outdoor air is completely cut off open.Cylindrical shell 3, panel 4 can adopt materials such as galvanized iron sheet, stainless sheet steel to make, and also can adopt plastics once injection molded.Turnover panel adopts iron and steel thin sheet to make.Only need during cleaning fan cap 6 is backed out,, clean cylindrical shell 3 inwalls easily with regard to desirable flabellum 2 down.Embodiment 1 is mainly used in the dead ahead window in kitchen.

Embodiment 2 as shown in Figure 3, Figure 4, as different from Example 1: turnover panel 17 is semicircle drop in leaf, is fixed on the cylindrical shell 16 through control agent 14 activities; Fixed head 18 tilts in cylindrical shell 16, and is attached thereto.The rotating shaft of control agent 14 is horizontally disposed with, and the opening of cylindrical shell 16 down.The angle of turnover panel 17 can be regulated by adjustable plate.Embodiment 2 is mainly used in the kitchen or hangs the dead ahead window in kitchen, and can avoid in use that outdoor air pours in down a chimney to indoor.

Embodiment 3 is as Fig. 5, shown in Figure 6.As different from Example 2: the turning cylinder of control agent 14 and horizontal direction are the 45 setting.Therefore, fixed head 21 is in the side top of cylindrical shell 19, and turnover panel 20 is in the side-lower of cylindrical shell 19.The air outlet of cylindrical shell 19 is at side-lower.Embodiment 3 is mainly used on the side window of hanging the kitchen, and air-out is smooth, and can avoid tobacco tar to pollute outdoor metope.
