Description

The cyclonic separation smoke exhaust

The utility model is a kind of cyclonic separation smoke exhaust, belongs to a kind of household electrical appliance.

The oily fume exhauster of family's use at present generally has two kinds: a kind of ventilating fan that is mounted in window or exhaust opening place, the fume exhausting fan that a kind of blower fan combines with fan housing.Ventilating fan simple and reasonable for structure, cheap, but because it is too far away apart from cooking stove, its suction effect is undesirable; And the ventilating fan oil dripping is serious, has polluted surrounding environment.And the plural motor of the general use of existing fume exhausting fan, complex structure, heaviness, fault is many, the price height, fan delivery is little, and a little less than the draft, the flue gas before the air intake machine is not purified yet, and makes the lampblack absorber internal corrosion serious, and the cleaning frequency is short, cleans difficulty.

The purpose of this utility model is: design a kind of rational in infrastructure, price is lower, the cyclonic separation smoke exhaust being convenient to clean.

The utility model comprises that the upper end has the exhaust fume collecting hood of exhaust opening, there is a middle part to have the cyclone separator that helical blade, top have longitudinal blade and is installed on the exhaust opening place, exhaust opening has a shell outward, have oil outlet on the exhaust fume collecting hood between cyclone separator and exhaust opening and the housing, cyclone separator below lubricating cup is installed.

The utility model has adopted existing cyclone separator, and the oil smoke that sucks exhaust fume collecting hood produces swirling eddy through the helical blade guiding, and particles such as oil droplet, water droplet get rid of under action of centrifugal force to housing, discharge through oil outlet along shell inner surface again.In addition, the oily vapour between longitudinal blade forms many little eddy current, and makes wherein oil, vapour be captured, and it makes that also the energy loss of swirling eddy is less simultaneously, and keeps stable.Oil on the cyclone separator, vapour flow to lubricating cup through its outer surface.This shows, obtained effective purification by cyclone separator oil vapour, can alleviate the pollution of oil smoke greatly surrounding environment through oil smoke of the present utility model.The utility model parts are less in addition, thereby with low cost, and it also has the characteristics of dismantling and cleaning be convenient to.

The exhaust opening place of exhaust fume collecting hood can be shaped on or install one and lead smoke pipe, and the cyclone separator helical blade partly is positioned at wherein.This leads smoke pipe can make cyclone separator be convenient to install on the one hand, can play guide effect to oil smoke on the other hand, guarantees flowing along the cyclone separator helical blade of oil smoke.

And its concrete following mode that can be of installing: also be shaped on inward flange leading going to the bottom of smoke pipe, going to the bottom of spiral separator helical blade part cooperates with this inward flange.

Clean-up effect for the oil smoke that guarantees to enter housing is shaped on a drainage tube, the upper end of drainage tube and housing upper end closed in the housing on cyclone separator top.

Oil droplet that flows down through housing and water droplet and can collect by lubricating cup separately by oil droplet and water droplet that cyclone separator flows down, also can collect by same lubricating cup, install oil pipe additional as the oil outlet place on exhaust fume collecting hood, and make it directly feed in the lubricating cup of cyclone separator below, perhaps oil pipe is led in the inner chamber of cyclone separator bottom, the hole of going to the bottom by its inner chamber communicates with the lubricating cup that is fixed on the cyclone separator below.

Go to the bottom at cyclone separator and to fix a screw rod, and, then lubricating cup can be fixed on the cyclone separator below by spinning of screw rod and threaded sleeve at the making threaded sleeve of going to the bottom of lubricating cup.

In the smoke exhaust pipe of exhaust fume collecting hood top the motor that has fan is installed preferably.

Motor is directly installed on the upper end of housing, perhaps is installed in the ventilating fan shell by support, and the ventilating fan shell then is fixed on the top of housing.

In addition, the inner surface of exhaust fume collecting hood should be streamlined, thereby strengthens collection cigarette effect.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Fig. 1 is the phantom of the utility model embodiment one user mode;

Fig. 2 is the phantom of the utility model embodiment two user modes;

Fig. 3 is the side-looking left view of embodiment one and embodiment two;

Wherein, the 1-bend pipe, the 2-motor, the 3-fan, 4-ventilating fan shell, the 5-pipe collar, the 6-drainage tube, the 7-housing, the 8-cyclone separator, 9-leads smoke pipe, 10-pipe collar, 11-exhaust fume collecting hood, 12-lubricating cup, 13-sleeve pipe, 14-screw rod, 15-sealing gasket, 16-oil pipe, 17-support.

Embodiment one:

As shown in Figure 1, present embodiment is made up of exhaust fume collecting hood 11, the lubricating cup 15 that is installed in housing 7 on the exhaust fume collecting hood 11, cyclone separator 8, cyclone separator 8 belows.The housing middle part of cyclone separator 8 has helical blade, and its top has longitudinal blade.Going to the bottom of the housing of cyclone separator 8 is fixed with a screw rod 14, and the lubricating cup 12 that is threaded sleeve pipe 13 of going to the bottom is connected with it.The exhaust fume collecting hood 11 of present embodiment is streamlined, and its upper end has an outlet flue, and what the outlet flue place had that tail band has an inward flange leads smoke pipe 9, and the helical blade of cyclone separator 8 partly is installed in leads in the smoke pipe 9, and it is gone to the bottom and cooperates with the inward flange of leading smoke pipe 9.Housing 7 is positioned at leads outside smoke pipe 9 and the cyclone separator 8, and its lower end is connected with exhaust fume collecting hood 11 by pipe collar 10.Housing 7 is the bigger reduced pipe of lower diameter, and its upper end has a drainage tube 6, the upper end closed of housing 7 and drainage tube 6 above cyclone separator 8.At housing 7 and lead on the exhaust fume collecting hood 11 between the smoke pipe 9 and be shaped on oil outlet, and have oil pipe 16 to be connected with it, oil pipe 16 leads in the cavity of cyclone separator 8 helical blades below, on the bottom surface of cyclone separator 8 cavitys oil outlet is arranged also.There is a screw rod 14 to be fixed on the bottom surface of cyclone separator 8.Lubricating cup 12 is positioned at the below of cyclone separator 8, the sleeve pipe 13 that it is gone to the bottom and has internal thread, this sleeve pipe 13 be fixed on the screw rod 14 that cyclone separator 8 goes to the bottom and spin.
