Abstract
The fan for split-type cooking fume extractor features that its blade wheel and motor all are packed in casing for rainproofing, an anti-backflow ring is installed under cover plate of fan's air inlet to prevent airflow returning, and an oil collecter composed of oil-stop plate, oil hole and oil-colecting box is installed at outlet of fan, so avoiding environmental pollution.
Description
The invention belongs to kitchen ware
The inventor has applied for " wall dual-hole oil soot extractor " (patent No.: 92205582.3) on April 3rd, 1992 to Patent Office of the People's Republic of China, it is a kind of separating kitchen ventilator, be that blower fan separates with smoking cover and is not contained in one, blower fan is adorned outdoor separately, advantage is to keep the kitchen noise free, next is that smoking cover does not contain blower fan, thereby volume is little, setting height(from bottom) can reduce half, the nearly draft of its distance is big, and smoking efficient improves 1 times, and its deficiency is that the blower fan that it adopts is the common blower fan of selling in the general city, exist following three problems: (1) motor all is an external mounted, be that motor is to be contained in flow blower casing outside, seal is poor, when being contained in outdoor rainy day, motor is intake easily, and is dangerous; (2) there is the return loss that air-flow flows backwards at draught fan impeller intake grill place; (3) blower fan does not have degreasing unit, and the tar in the oil smoke drips directly from fan outlet ejection, pollution wall and outdoor environment.
The object of the present invention is to provide and a kind ofly have the reduced return loss De ， And that do not drenched with rain of protection motor and can prevent that tar from dripping from the blower fan that is used for separating kitchen ventilator of exhaust outlet ejection.
What the present invention proposed is a kind of blower fan of separating kitchen ventilator, comprises centrifugal or the turbo type impeller, flow blower casing, and intake grill cover plate and motor is characterized in that:
(1) it is an integrated blower fan, and promptly impeller and motor all are contained in flow blower casing the inside, guarantees that motor avoids drenching with rain;
(2) under the air inlet cover plate, be equipped with one and prevent that air-flow is back to the anti-backflow circle (1) of impeller intake grill from the impeller exhaust outlet, the diameter of this anti-backflow circle is a bit larger tham the external diameter of impeller intake grill to be inserted in the outside of impeller, this gap is healed better little, is principle not collide.Because integrated blower fan, motor are in the Fan casing the inside, the thickness of Fan casing certainly will increase, and the gas backstreaming loss enlarges markedly.
(3) a cover degreasing unit is housed at the exhaust outlet place of blower fan, after oil smoke is drawn into blower fan, oil droplet is thrown on the blower fan scroll casing shape side plate all around by centrifugal force, when side plate flows to exhaust outlet, the oil-shutting-off plate (9) that is installed in outer panel inboard, fan outlet place is held back, and flows into oil box (7) lining through oil flow hole (10).
Above-mentioned degreasing unit can divide two kinds of structures:
(1) is used for the horizontal degreasing unit that horizontal fan is installed, it is by oil-shutting-off plate (9), oil flow hole (10), keep off oily dam (8) and oil box (7) and form, its oil-shutting-off plate is contained in the vertical outer panel inboard in blower fan outlet port, it highly equals the outer panel height, the oil droplet that is trapped is past dirty along oil-shutting-off plate, oil flow hole on the exhaust outlet base plate (10) flows into oil box (7) lining, and also horizontal on the horizonal base plate at fan outlet place have one to prevent that the oil on the base plate is from the oily dam (8) of the retaining of exhaust outlet outflow.
(2) be used for the vertically arranged vertical degreasing unit of blower fan, it is by oil-shutting-off plate (12), stream hydraulic fluid port (13) and oil box (14) are formed, oil-shutting-off plate is contained in the outer panel inboard that the fan outlet place is in a horizontal position, and the stream hydraulic fluid port (13) on the blower fan outer panel of the oil that is trapped below being positioned at oil-shutting-off plate flows into oil box (14) lining.
Also have following 3 common traits in the above-mentioned horizontal or vertical degreasing unit: (1) oil-shutting-off plate has two kinds of forms: (I) slot type oil-shutting-off plate (9) or (12), (II) ramp type oil-shutting-off plate (15).
(2) oil box has three kinds of forms: (I) duck tongue type oil box, to form by duck tongue (16) and box body (17), and it is stuck in the outer rim of fan outlet place horizonal base plate; (II) spile type oil box, by plate (19), box body (18) and slot (20) are formed; (III) clamping-type oil box is made up of bayonet mount (22) and dop box body (21), and bayonet socket can be made the screw bayonet socket, also can make the pin bayonet socket.
(3) there is one to prevent waft rain shade in the degreasing unit of rainwater at flow blower casing exhaust outlet place, it is the rain shade (5) of the likeness in form del of looking from the side, fusing with the end face and the bi-side at flow blower casing exhaust outlet place, perhaps also can be to stretch out a weather shield on the end face at fan outlet place.
The blower fan of above-mentioned separating kitchen ventilator, its feature also is a non-proliferation circle (6) that prevents that air-flow from spreading so that causing stream swirl to lose to the inboard when flow blower casing rotates is being housed on the base plate of its flow blower casing, this non-proliferation loop diameter equals or is slightly smaller than leaf to state lower port diameter, and it highly equals or is slightly smaller than the distance of impeller end opening bottom surface to base plate.
The blower fan of separating kitchen ventilator of the present invention, compare the advantage that is had with existing common blower fan: (1) integrated structure is contained in the outdoor motor of protecting is not exposed to the sun and rain, and motor is not intake, and Security is good; (2) air inlet has the anti-backflow circle, and the non-proliferation circle is arranged on the base plate, has improved the efficient of blower fan; (3) solved the environmental pollution problem that the fan outlet oil spout is caused.
