Abstract
The utility model discloses a wind-guide ring structure of a fume exhauster, the structure of which is annularity, comprising the wind-guide pipeline of an inner ring and an outer ring evaginated and extended at the inlet of the wind-guide pipeline. The utility model is characterized in that the outer ring of the wind-guide ring is extended outwards with a supporting seat. A magnet is inserted in the supporting seat. The wind-guide ring is adsorbed to the volute shell of the fume exhauster through the magnet. The utility model has the advantages that tools are not needed when the utility model is assembled and disassembled, and the corresponding structure of a nut seat and a blocking buckle seat is not needed to be arranged on the volute shell, which reduces the difficulty of production and manufacture and improves the production efficiency.
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.Though can reduce greatly to its frequency of cleaning, the inside of the lampblack absorber especially cleaning of impeller also is absolutely necessary, in addition, also need be thought of as possible maintenance and provide convenience.In the time of need cleaning draught fan impeller, lampblack absorber is inner and needs the maintenance blower fan at lampblack absorber, the parts that air-ducting ring, guard assembly, exhaust fume collecting hood, air inlet circle etc. need be positioned at impeller the place ahead disassemble fully, could take out blower fan then and keep in repair and clean.And air-ducting ring of the prior art is fixedly mounted on the spiral case with many screws or buckle form, needs the professional to utilize the expensive time of instrument just to open and reinstall for this reason, and the user through specialized training is not difficult to clean voluntarily.Moreover, on spiral case, corresponding constructions such as nut seat or snap seats must be set for this reason, so both increase the difficulty of manufacturing and also reduced production efficiency.
Summary of the invention
Technical problem to be solved in the utility model be exploitation a kind of simple and reasonable, dismounting is very simple and easy, need not to be provided with the air-ducting ring structure of the range hood of corresponding construction on the spiral case.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the air-ducting ring structure of this range hood, it is structure in the form of a ring, comprise the wind-guiding pipeline of inner ring and the outer ring of turning up and extending by this wind-guiding pipeline porch, it is characterized in that described air-ducting ring outer ring has extended bearing laterally, but setting-in magnet in the bearing, 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.
It is the fillet of 2mm～50mm that the transition position design of described wind-guiding pipeline and outer ring has R, takes all factors into consideration size and effect, and 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.
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, air-ducting ring adopts magnetic structure, so that 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, so both reduce the difficulty of manufacturing and improved production efficiency yet; 2, the fillet of air-ducting ring porch design meets hydrodynamics, helps reducing the air intake resistance, improves the suction of range hood; 3, the design of oil outlet opening direction on the air-ducting ring, both can reduce on business the return air that is produced under the too high situation of flue blast altogether flows out sucking the interference and the retardance of air-flow from oil outlet, thereby raising suction can prevent oil outlet effluent stream excessive velocities under this situation again and carries greasy dirt secretly and directly pass oil cleaner screen.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, comprise the wind-guiding pipeline 1 of inner ring and the outer ring 2 of turning up and extending by this wind-guiding pipeline 1 porch, the outer ring 2 of air-ducting ring has evenly extended four bearings 3 laterally, but setting-in magnet 4 in the bearing 3, air-ducting ring can be adsorbed on the spiral case 7 of lampblack absorber by this magnet 4.In addition, for reducing the air intake resistance, it is the fillet of 10mm that the transition position design of wind-guiding pipeline 1 and outer ring 2 has R.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.
Claims (6)
1, a kind of air-ducting ring structure of range hood, it is structure in the form of a ring, comprise the wind-guiding pipeline of inner ring and the outer ring of turning up and extending by this wind-guiding pipeline porch, it is characterized in that described air-ducting ring outer ring has extended bearing laterally, but setting-in magnet in the bearing, air-ducting ring can be adsorbed on the spiral case of lampblack absorber by this magnet.
