Abstract
The utility model discloses a jet-suction cooking fume exhauster. The fan of the utility model is arranged on the outside of a smoke exhaust pipeline. According to the jet theory, the smoke exhaust pipeline comprises a smoke collection cover, a reducing pipe, a throat, a diffusion pipe, etc., wherein, one end of a blower pipe is connected with the outlet of the fan; the other end of the blower pipe is provided with a nozzle; the nozzle is stretched into the inside of the smoke exhaust pipeline; the direction of a nozzle outlet aims to the throat; the direction of the nozzle outlet and the throat are on the same coaxial line; the smoke cover is inclined relative to a stove plane; the smoke collection cover is near to the stove plane. The utility model has the advantages of simple structure, free dismounting, easy cleaning, no oil leakage, sufficient and reliable cooking fume suction and exhaustion, large suction force, high efficiency of cooking fume suction, etc. Besides, the power parts of the fan are free from oil and fume pollution.
Description
The utility model relates to a kind of parts of home furnace, particularly a kind of spray-sucking type smoke exhaust ventilator.
Commercially available smoke exhaust ventilator mostly is the axial flow blower formula at present, and its blower fan places smoke discharging pipe inside, complex structure; Unpick and wash difficulty; Oil leakage phenomenon is more serious; Oil smoke, steam etc. directly pollute the blower fan power part and accumulate grease, cause electrical machinery life and fan efficiency to descend.The disclosed carefree fume exhausting fan of CN2090027U, blower fan is placed the outside of smoke discharging pipe, it is inner and towards the smoke evacuation direction that blower fan outlet extends to smoke discharging pipe, exit flow drive waste gas moves upward and discharges through smoke discharging pipe, its major defect is the design spray application technique not of smoke discharging pipe, be difficult in smoke discharging pipe, produce negative pressure reliably, reach the purpose of effective fume exhaust.Because smoke pumping efficient is low, it is indoor to cause oil smoke to fill the air, and wherein a part is sucked by blower fan, again blower fan is polluted.In addition, its exhaust fume collecting hood is identical with commercially available smoke exhaust ventilator to be arranged horizontally, so exhaust fume collecting hood must be installed in from kitchen range face higher position not influence operations such as the cooking, like this to the suction of oil smoke a little less than, smoking efficient is lower.
The purpose of this utility model be to overcome the above-mentioned weak point of existing smoke exhaust ventilator and provide a kind of simple in structure, exempt to dismantle easy cleaning, avoid oil dripping, blower fan is not subjected to oil, contaminated vapor and the pump drainage oil smoke is fully reliable, draft is big, efficient is high spray-sucking type smoke exhaust ventilator.
The purpose of this utility model is achieved through the following technical solutions: the spray-sucking type smoke exhaust ventilator comprises blower fan and spray intake and blowing device, and blower fan is fixed in the outside of spray intake and blowing device.Spray intake and blowing device spray application technique is designed to contain the ajutage of exhaust fume collecting hood, reducing pipe, trunnion, anemostat, band nozzle etc.Exhaust fume collecting hood, reducing pipe, trunnion, the anemostat composition smoke discharging pipe that joins successively wherein, ajutage one end links to each other with the blower fan outlet, the other end stretches into smoke discharging pipe inside, nozzle on it in reducing pipe and and reducing pipe between form an annular space, the jet expansion direction is aimed at trunnion, and with reducing pipe, trunnion, anemostat coaxial line.
Spray-sucking type smoke exhaust ventilator discrete and horizontal two kinds of structures.In vertical structure, the smoke discharging pipe axis is for being arranged vertically and parallel with exhaust fume collecting hood smoking direction; In horizontal type structure, the smoke discharging pipe axis is arranged horizontally and is vertical with exhaust fume collecting hood smoking direction.Exhaust fume collecting hood is up-small and down-big toroidal, and last cover mouth connects reducing pipe, the play cover angle that mouthful tilts towards the also relative cooking stove plane of cooking stove.From covering a mouthful joint face that covers mouth extremely down is plane or curved surface.Being shaped as of trunnion is cylindrical or conical.The one section ajutage that is positioned at smoke discharging pipe is detachable.
Because spraying technique has been used in the design of spray intake and blowing device, when smoke exhaust ventilator is worked, can produce negative pressure reliably in the trunnion, reaches the purpose of effective fume exhaust; Blower fan places outside the smoke discharging pipe, can not be subjected to oil, contaminated vapor; Simple in structure, be easy to make; Oil smoke contacts site such as exhaust fume collecting hood are cleaned very easily, unload clean behind the ajutage in the oil-drain pipe more convenient; Smoke discharging pipe is not generally assembled oil-collecting and is dripped, because simple in structure, has oil droplet to be easy to remove yet, therefore can leakage of oil; Cover mouthful relative cooking stove plane is tilting down for exhaust fume collecting hood, and exhaust fume collecting hood can be installed in from the nearer position of kitchen range face does not influence operations such as the cooking, and therefore the draft to oil smoke further strengthens, and smoking efficient further improves.
Fig. 1 is vertical spray-sucking type smoke exhaust ventilator front view;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is horizontal spray-sucking type smoke exhaust ventilator structure chart.
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is made and to further describe.
Vertical as shown in Figure 1 and Figure 2 spray-sucking type smoke exhaust ventilator, exhaust fume collecting hood 1, reducing pipe 2, trunnion 3, anemostat 4 join successively (can whole make or segmentation connects after making again) form a smoke discharging pipe, its axis normal is arranged, and parallel with exhaust fume collecting hood 1 smoking direction, anemostat 4 afterbodys connect a bend pipe 8.Exhaust fume collecting hood 1 is made up-small and down-big toroidal, and last cover mouth connects reducing pipe 2, and play cover mouthful and the cooking stove plane 45 ° of left and right sides angles that tilt mouthful are that several intersecting planes enlarge gradually to a joint face that covers mouth down from cover, smooth and easy in order to fume exhaust.Trunnion 3 is cylindrical, and anemostat 4 is up big and down small taper shape.Blower fan 5 is fixed in the outside of smoke discharging pipe.The ajutage 6 of band nozzle 7 is made bend pipe, and the outlet of an end and blower fan links to each other, and the other end extends smoke discharging pipe inside from the sidewall of reducing pipe 2, the nozzle 7 on it in reducing pipe 2 and and reducing pipe 2 between formation one annular space.Nozzle 7 Way outs are aimed at trunnion 3, and with reducing pipe 2, trunnion 3, anemostat 4 coaxial lines.Ajutage 6 is positioned at one section detachable and following cover mouthful taking-up from collecting cigarette 1 of smoke discharging pipe, makes pipe blow-through more convenient.
When the blower fan rotation, high velocity air manages 6 from nozzle 7 directive trunnions 3 in sending, in trunnion 3, produce negative pressure, the oil smoke that the cooking stove and the cooking produce constantly is being pressed into trunnion 3 from exhaust fume collecting hood 1 through the annular space between nozzle 7 and the reducing pipe 2 under the atmospheric pressure effect, mix after anemostat 4 deceleration superchargings are discharged outdoor through bend pipe 8 again with the high velocity air that nozzle 7 penetrates.
Horizontal as shown in Figure 3 spray-sucking type smoke exhaust ventilator, its smoke discharging pipe axis horizontal is arranged and is vertical with exhaust fume collecting hood 1 smoking direction.Exhaust fume collecting hood 1 to go up cover mouthful to the joint face of cover down mouthful be streamlined curved surface.Ajutage 6 is made straight tube, termination blower fan outlet, and the other end stretches into smoke discharging pipe inside from exhaust fume collecting hood 1 top, its top nozzle 7 is positioned at reducing pipe 2 and forms an annular space with reducing pipe 2, trunnion 3 be shaped as taper shape, big termination reducing pipe 2, small end connects anemostat 4.Anemostat 4 afterbodys directly stretch out the open air.
