Abstract
The utility model discloses a wind wheel of an extractor hood. The wind wheel comprises a first supporting ring, a second supporting ring and blades, wherein a third supporting ring is further arranged between the first supporting ring and the second supporting ring. The blade between the first supporting ring and the third supporting ring is as long as the blade between the second supporting ring and the third supporting ring. The third supporting ring is provided with a supporting bracket. The length of the single blade among the supporting rings is greatly shortened through the third supporting ring installed between the first supporting ring and the second supporting ring, so that the non-deformability of the blades is improved and the service life of the blades is prolonged. A driving device is fixedly arranged through the third supporting ring, so that the operating stability of the driving device is ensured.
Description
Technical field
The utility model relates to a kind of range hood wind wheel.
Background technology
Now widely used range hood wind wheel generally only comprises the blade of two support rings and support ring support.In lampblack absorber when running,, wind speed round is higher, and blade is under centrifugal action, and after long-time the use, the situation of being out of shape easily appears in blade, affects the operational efficiency of lampblack absorber.
The drive unit of range hood generally is fixed on the air-ducting ring base plate, and under motor ran up situation, vibration obviously caused stable equipment operation relatively poor.
The utility model content
The utility model is for the deficiencies in the prior art, and purpose is to provide the range hood wind wheel that a kind of non-deformability is strong, can strengthen the drive unit operation stability.
The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of range hood wind wheel, comprise the first support ring, the second support ring and blade, also be provided with three-support ring in the middle of the first support ring and the second support ring, length of blade between described the first support ring and three-support ring is identical with the length of the blade between the second support ring and three-support ring, and described three-support ring is provided with supporting bracket.
The beneficial effects of the utility model are: by being arranged on the middle three-support ring of the first support ring and the second support ring, greatly shortened the monolithic length of blade between support ring, improved the non-deformability of blade, extended the service life of blade; Drive unit is fixing by three-support ring, the stability when having guaranteed the drive unit operation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model three-support ring schematic diagram.
In figure: the first support ring 1, the second support ring 2, blade 3, three-support ring 4, supporting bracket 5
The specific embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
As shown in Figure 1, a kind of range hood wind wheel comprises the first support ring 1, the second support ring 2 and blade 3, has increased three-support ring 4 in the middle of the first support ring 1 and the second support ring 2.Blade 3 length between the first support ring 1 and three-support ring 4 are identical with the length of the blade 3 between the second support ring 2 and three-support ring 4.Described three-support ring 4 is provided with the supporting bracket 5 for drive unit.
The support ring of the utility model wind wheel and blade 3 are by after punch forming, adopt the mode of welding to connect, product is compared with the range hood wind wheel of routine, has greatly shortened the monolithic length of blade 3 between support ring, improve the non-deformability of blade 3, extended the service life of blade; Drive unit is fixing by three-support ring 4, the stability when having guaranteed the drive unit operation.
