Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 2, the centrifugal blower of the present embodiment comprises housing 10, centrifugal wind wheel and diversion division 30, housing 10 have inner chamber and with the intake grill of inner space and exhaust outlet, centrifugal wind wheel to be arranged in housing 10 and rotationally between intake grill and exhaust outlet, intake grill and exhaust outlet are oppositely arranged, and the inwall that diversion division 30 is arranged on housing 10 is positioned at the outer circumferential of centrifugal wind wheel.
The centrifugal blower of application the present embodiment, centrifugal blower comprises housing 10, centrifugal wind wheel and diversion division 30, housing 10 have inner chamber and with the intake grill of inner space and exhaust outlet, centrifugal wind wheel is arranged in housing 10 rotationally and between intake grill and exhaust outlet, intake grill and exhaust outlet are oppositely arranged.When centrifugal blower runs, centrifugal wind wheel rotates, and by the inside of the air intake housing 10 of the air inlet of housing 10, the air of suction enters in centrifugal wind wheel, under the centrifugal effect of centrifugal wind wheel, air-flow flows to the inwall of housing 10 from the radial exhaust outlet of centrifugal wind wheel.The inwall that diversion division 30 is arranged on housing 10 is positioned at the outer circumferential of centrifugal wind wheel.Diversion division 30 has the effect of guiding air-flow, the exhaust outlet of the air-flow guide housings 10 that the radial direction from centrifugal wind wheel can be flowed out.The air-out direction of the exhaust outlet of such housing 10 is just identical with the air intake direction of the intake grill of housing 10, diversion division 30 changes the air-out direction of centrifugal blower, make the air-out direction variation of centrifugal blower, add the alternative of centrifugal blower, the demand of different user can be met.
In the present embodiment, diversion division 30 is multiple, and multiple diversion division 30 is evenly arranged on the inwall of housing 10 along the circumference of centrifugal wind wheel.Multiple diversion division 30 can by more air-flow guiding exhaust outlet, make the air-flow that flows out from exhaust outlet evenly, improve the air duct performance of centrifugal blower.In order to make diversion division 30 adapt with the structure of housing 10, preferably, diversion division 30 is four.
As shown in Figure 3 and Figure 4, in the present embodiment, the first guide face 31, first guide face 31 that diversion division 30 comprises for the air-flow from centrifugal wind wheel being directed to exhaust outlet raises from air inlet gradually obliquely to exhaust outlet.The air-flow of centrifugal wind wheel can be directed to exhaust outlet by the first guide face 31, makes air flow direction exhaust outlet more, effectively improves the working efficiency of centrifugal blower.Preferably, the first guide face 31 is projected as spiral of Archimedes in the plane of the axis perpendicular to centrifugal wind wheel.First guide face 31 moves up with can making flow spiral, water conservancy diversion better effects if.
In the present embodiment, the second guide face 32, second guide face 32 that diversion division 30 also comprises the inwall for the air-flow from centrifugal wind wheel being directed to housing 10 is crossing with the first guide face 31, and the second guide face 32 is perpendicular to intake grill.Wherein, intake grill is perpendicular to the axis of centrifugal wind wheel.Air-flow is extruded at the second guide face 32 and is accelerated at this after flowing out from the radial exhaust outlet of centrifugal wind wheel, and due to supplementing of follow-up air-flow, airflow passes second guide face 32 inwall towards housing 10 move.Then air-flow at the flows by action of the first guide face 31 to the exhaust outlet of housing 10.Preferably, the second guide face 32 is in arc surfaced.Air-flow can be directed to the inwall of housing 10 by arc surfaced better.In order to better air-flow is directed to the inwall of housing 10 further, more preferably, the second guide face 32 is in hyperbolic planar.Air-flow can be made like this to move along helicoid, and guide effect is better.
In the present embodiment, the second guide face 32 of a diversion division 30 in two adjacent diversion divisions 30 is connected with the first guide face 31 of another diversion division 30.Such air-flow flows to the first guide face 31 immediately after flowing through the second guide face 32, makes the process of circulation of air-flow more smooth and easy, and guiding draught effect is better.
In the present embodiment, the motor 70 that centrifugal blower also comprises supporting component 60 and is arranged on supporting component 60, centrifugal wind wheel is arranged on supporting component 60 rotationally, and supporting component 60 is arranged on exhaust outlet place, and motor 70 drives with centrifugal wind wheel and is connected.Supporting component 60 is for supporting centrifugal wind wheel and fixed electrical machinery 70.Motor 70 drives centrifugal wind wheel to rotate, and can ensure the normal operation of centrifugal blower.
As shown in Figure 2 and Figure 5, in the present embodiment, multiple blades 20 that centrifugal wind wheel also comprises shroud 40, hub disk 50 and is arranged between shroud 40 and hub disk 50, shroud 40 has air inlet through hollow shaft mouth, the air intake direction of air inlet through hollow shaft mouth is identical with the air intake direction of intake grill, and shroud 40 is in arc surfaced.The shroud 40 of arc surfaced can make air-flow have acute angle between the air intake direction and air-out direction of centrifugal wind wheel, airflow ground can be made so more smooth and easy, thus effectively improve the air duct performance of centrifugal blower.
The flow process that air-flow enters housing 10 inside is as follows:
When startup power supply, centrifugal blower runs, centrifugal wind wheel entry into service, air-flow between first blade 21 and the second blade 22 is due to the effect of the pressure side of the first blade 21, the runner (shown in Fig. 6) that air-flow will be thrown out of between the first blade 21 and the second blade 22, enter the C region between the second blade 22 and the second guide face 32, and be extruded in C region and be accelerated, and D region obtain along the second guide face 32 tangential velocity (as shown in Figure 7), supplementing subsequently due to follow-up air-flow, the air-flow accelerated will enter region E (as shown in Figure 8), at region E owing to being provided with the first guide face 31, thus make air-flow have speed (as shown in Figure 9) on vertical direction.Air-flow flows over C region, D region and E region in housing 10.Owing to there are 4 identical diversion divisions 30, the air-out on the surface at vertical exhaust outlet can be made more even.
The application also provides a kind of air cleaner, and the embodiment according to the air cleaner of the application comprises centrifugal blower, and centrifugal blower is above-mentioned centrifugal blower.Diversion division 30 has the effect of guiding air-flow, the exhaust outlet of the air-flow guide housings 10 that the radial exhaust outlet from centrifugal wind wheel can be flowed out.The air-out direction of the exhaust outlet of such housing 10 is just identical with the air intake direction of the intake grill of housing 10, diversion division 30 changes the air-out direction of centrifugal blower, make the air-out direction variation of centrifugal blower, add the alternative of centrifugal blower, the demand of different user can be met.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
