Abstract
A blade-free fan device relates to a fan device. The device comprises a pedestal (1) and a nozzle (2) arranged on the pedestal, wherein the pedestal accommodates a component used for generating air flow passing through the nozzle; and the nozzle comprises an internal passage (3) for receiving the air flow from the pedestal and a vent (4). The air flow is jetted through the vent. The nozzle is extended in a substantially orthogonal manner on an axis (X) to limit an opening (5). Air outside a fan is sucked by the air flow jetted from the vent through the opening. The fan device is characterized in that: the component comprises a motor (6) and an impeller (7) fixed on a rotary shaft of the motor, wherein a rotary shaft (8) of the impeller is approximately parallel to the axis (X). The device has the characteristics of high working efficiency, large air outlet amount, low noise and the like.
Description
Technical field
The present invention relates to a kind of fan assembly.
Background technique
The Chinese patent application that on May 6th, 2009, publication number was CN 101424278A (application number: 200810177843.3) disclose a kind of no blade fan device that is used to produce air stream, this kind fan comprises: pedestal and the nozzle that is installed on the described pedestal, be provided with the member that is used to produce by the air-flow of described nozzle in the pedestal, its member comprises motor and the impeller that is arranged on the motor shaft, its nozzle has inner passage and the relief opening that is used to receive from the air-flow of pedestal, it is injected that air communication is crossed described relief opening, nozzle extends orthogonally basically about axis and limits opening, and described fan air outside is aspirated by the air-flow that sprays from described relief opening by described opening.Because the rotatingshaft of its impeller of this kind fan is parallel with the symmetry axis of cylindric pedestal, and the direction of air-flow turnover impeller is roughly the symmetry axis direction of pedestal, and the symmetry axis approximate vertical of the direction of the centrifugal force of the driving air current flow of impeller and pedestal, so its efficient that drives air current flow of this kind fan is very low; This kind fan also is provided with diffuser at impeller to the air-flow path of nozzle in addition, has hindered flowing of air-flow, has further reduced working efficiency.
Summary of the invention
The present invention aims to provide a kind of improved fan assembly to overcome above-mentioned defective of the prior art.The no blade fan device that will provide a kind of working efficiency higher is provided.
In order to achieve the above object, the technical solution used in the present invention is: a kind of no blade fan device that is used to produce air stream, described fan comprises: pedestal and the nozzle that is installed on the described pedestal, described pedestal holds the member that is used to produce by the air-flow of described nozzle, described nozzle comprises inner passage and the relief opening that is used to receive from the air-flow of described pedestal, it is injected that air communication is crossed described relief opening, described nozzle extends orthogonally basically about axis and limits opening, described fan air outside is aspirated by the air-flow that sprays from described relief opening by described opening, it is characterized in that, described member comprises motor and the impeller, the rotatingshaft of described impeller and the described axis almost parallel that are fixed on the described motor rotation axis.
Preferably, described impeller has part to be positioned at the upper end open place of described pedestal; Described impeller adopts centrifugal impeller usually; Described impeller can adopt metallic material manufacturing, also can adopt plastic materials manufacturing, can also adopt other material to make.
Described motor can be an inner rotor motor, also can be external rotor electric machine; Described motor can be an AC induction motor, and dc brushless motor can also be other motor.
Described pedestal can adopt multiple shape, can be roughly cylindrically, can partly be cylindrical also, can also other shape; Described pedestal can be about described axis symmetry; Described pedestal can be provided with suction port in its side.
Described nozzle limits an opening at least, for example can limit plural opening; The shape of its opening can be multiple shape, can be circular, oval, round rectangle, also can be the part annular, can also be other shape.
Described relief opening is set on the loop wall around the nozzle of described opening, so that the effectively suction of air-flow institute that described fan air outside is sprayed from described relief opening by described opening.
The present invention has following good effect:
Because its rotatingshaft of impeller and the described axis almost parallel of apparatus of the present invention, the centrifugal force that impeller was produced when it rotated can drive the rapid movement of air-flow more effectively and can enter to low-loss the inner passage of nozzle; Its air output is bigger during apparatus of the present invention operation; In addition, its intake grill of the impeller of apparatus of the present invention and exhaust outlet are bigger, and its air-flow is also lower at the noise of impeller intake grill and the formation of exhaust outlet place.
Description of drawings
Fig. 1 is a no blade fan schematic representation of apparatus of the present invention;
Fig. 2 is a no blade fan device shown in Figure 1 generalized section along axis;
Fig. 3 is another embodiment of no blade fan device of the present invention.
Embodiment
Fig. 1 is a no blade fan schematic representation of apparatus of the present invention.As seen from the figure, apparatus of the present invention comprise: pedestal 1 and the nozzle 2 that is installed on the pedestal 1, in pedestal, be provided with the member that is used to produce by the air-flow of nozzle 2, and with reference to figure 2, its nozzle comprises inner passage 3 and relief opening 4, it is injected that air communication is crossed relief opening 4, nozzle 2 extends orthogonally basically about axis X and limits opening 5, described fan air outside is aspirated by the air-flow that sprays from relief opening 4 by opening 5, its member comprises motor 6 and the impeller 7 that is fixed on the motor rotation axis 8, impeller 7 is a centrifugal impeller, and its rotatingshaft 8 and axis X almost parallel, impeller 7 have part to be positioned at the upper end open place of pedestal 1.Be provided with intake grill 10 in the side of pedestal 1, motor 6 is fixed on the fixed block 9.From figure, find out easily, this kind structure, the centrifugal force that impeller was produced when it rotated can drive the rapid movement of air-flow effectively and can enter to low-loss the inner passage of nozzle.
When this kind fan assembly uses, be positioned at motor 6 drives impeller 7 work of pedestal 1, air can be drawn into from a plurality of intake grills 10 that are positioned at pedestal 1 side 8, send in the inner passage 3 of nozzle 2 through acceleration or after boosting, and be deflated mouthful 4 ejections and flow out opening 5, be deflated mouthful 4 air-flows that sprayed from the air of ambient, external environment by opening 5 and entrainment, air-flow that is ejected and the air-flow that entrainmented are in conjunction with the total air flow that penetrates forward from nozzle 2 with generation.
