Abstract
The utility model discloses a wind-guide ring structure of a fume exhauster with less wind resistance, the structure of which is in a ring shape, comprising a wind-guide pipeline of the inner ring and an outer ring everting at and extending from the inlet of the wind-guide pipeline. The utility model is characterized in that a round corner with the radius of from 2 mm to 50 mm is arranged on the transition part of the wind-guide pipeline and the outer ring. Additionally, the opening direction of the oil outlet opening of the inlet end of the wind-guide ring points to the center of the wind-guide ring. The utility model has the advantages that the resistance of the wind inlet is small and the oil pollution can be prevented from drilling through the oil filtrate net because the speed of the flowing out airflow of the oil outlet hole is too fast on the condition that the returning wind exists.
Description
Technical field
The utility model relates to the air-ducting ring structure of a kind of parts of range hood, particularly a kind of range hood.
Background technology
Now, range hood has become one of requisite cooking apparatus of average family, and the lampblack absorber that wherein adopts centrifugal blower is so that its relative suction is big, noise is lower and can be well received need not in period than long running to clean.The existing range hood of centrifugal blower that adopts has generally comprised casing, spiral case and exhaust fume collecting hood are installed in the casing, impeller is installed in the spiral case, have air intake vent and the concentric air inlet of impeller on the exhaust fume collecting hood with spiral case, air inlet is equipped with guard assembly, air inlet circle, and air-ducting ring is equipped with at the air intake vent place of spiral case.The main effect of air-ducting ring is: reduce on business flue blast altogether and cross the negative effect to lampblack absorber smoking effect of the return air that produced under the high situation, and guide outside oil smoke to enter the impeller center.But existing air-ducting ring, the transition of its porch and guard assembly is very unreasonable, easily stays the dead angle, and causes air-flow in this turbulization, blocks the smooth and easy suction of oil smoke, influences the suction of blower fan.In addition, for top-sucking kitchen ventilator, also have the oil outlet that allows greasy dirt flow out on the air-ducting ring, and the opening of this oil outlet down.Because having under the situation of return air, the back side of oil outlet is malleation, so such shortcoming that is provided with has two: one, return air will make the oil outlet outflow be the air-flow of adverse current with respect to sucking air-flow, will disturb and block the smooth and easy suction that sucks air-flow, thus the inspiratory effects of reduction lampblack absorber; The 2nd, having under the situation of return air, the greasy dirt that flows out from oil outlet will may spill with big speed under the effect of carrying secretly of air-flow due to the return air, thereby passes the oil cleaner screen of guard assembly, directly fall into the pot in or gas range on, cause the pollution of food or make gas range dirty.
Summary of the invention
Technical problem to be solved in the utility model is a kind of simple and reasonable, air-ducting ring structure that the air intake windage is little of exploitation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the air-ducting ring structure of the range hood that this windage is little, it is structure in the form of a ring, comprise the wind-guiding pipeline of inner ring and the outer ring of being turned up and being extended by this wind-guiding pipeline porch, it is the fillet of 2mm～50mm that the transition position design that is characterised in that described wind-guiding pipeline and outer ring has R.Take all factors into consideration size and effect, the radius R of fillet is preferably 5～20mm.
The inlet end of described air-ducting ring has oil outlet, and the opening direction of oil outlet points to the air-ducting ring center.
Described air-ducting ring outer ring has extended bearing laterally, but setting-in magnet in the bearing, and air-ducting ring can be adsorbed on the spiral case of lampblack absorber by this magnet.The number of described bearing is 2～6, for taking all factors into consideration of effect and cost, generally is advisable with 3～4.
The described air-ducting ring back side forms groove along hoop, but embedded sealing ring in the groove.
Compared with prior art, advantage of the present utility model is: 1, the fillet of air-ducting ring porch design, meet hydrodynamics, and help reducing the air intake resistance, improve the suction of range hood; 2, the design of oil outlet opening direction on the air-ducting ring, both can be reduced under the situation of return air the oil outlet effluent stream to sucking the interference and the influence of air-flow, thereby raising suction can prevent from again to carry greasy dirt secretly because of the effluent stream excessive velocities of oil outlet under the situation of return air and directly pass oil cleaner screen having.3, air-ducting ring adopts magnetic structure, so as with being connected of spiral case, tool free when its advantage is dismounting, and therefore corresponding constructions such as nut seat or snap seats need be set on the spiral case, the difficulty that had so both reduced the manufacturing has also improved production efficiency; But 4, embedded sealing ring in the groove at the air-ducting ring back side, thereby can between air-ducting ring and spiral case, form good sealing, thus prevent that oil droplet from entering in the cabinet, and sealing is reliable.
Description of drawings
Fig. 1 is the schematic perspective view of the air-ducting ring structure of the utility model embodiment;
Fig. 2 is the front view of air-ducting ring among Fig. 1;
Fig. 3 has been equipped with A-A cutaway view behind sealing ring and the magnet for air-ducting ring among Fig. 2.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As Fig. 1～illustrated in Figure 3, be a preferred embodiment of the present utility model.As Fig. 1～shown in Figure 3, the air-ducting ring structure of present embodiment range hood, it is structure in the form of a ring, comprises the wind-guiding pipeline 1 of inner ring and the outer ring 2 of being turned up and being extended by this wind-guiding pipeline 1 porch.For reducing the air intake resistance, wind-guiding pipeline 1 can design the fillet that R is 2mm～50mm with the transition position of outer ring 2, and the radius of corner R in the present embodiment is 10mm.In addition, the outer ring 2 of air-ducting ring has evenly extended four bearings 3 laterally, but setting-in magnet 4 in the bearing 3, and air-ducting ring can be adsorbed on the spiral case 7 of lampblack absorber by this magnet 4.The inlet end of air-ducting ring evenly forms four oil outlets 5 along hoop, and the opening direction of oil outlet 5 points to the air-ducting ring center.For make air-ducting ring can and spiral case 7 between form good sealing, thereby prevent that oil droplet from entering in the lampblack absorber cabinet, the air-ducting ring back side forms groove along hoop, but embedded sealing ring 6 in the groove.
