Abstract

The invention discloses a bladeless fan device and relates to a fan device. The device comprises a base (1) and a nozzle (7) arranged on the base, wherein the base is used for accommodating a member generating airflow passing through the nozzle; the nozzle comprises an inner channel (3) for receiving the airflow from the base, and an exhaust port (4); when the airflow is ejected through the exhaust port, the nozzle is basically orthogonally extended to limit an opening (5) relative to an axis (X); and air outside the fan device is sucked by the airflow ejected from the exhaust port. The fan device is characterized in that: a muffling layer (6) is at least arranged on partial channel wall of the inner channel. The device has the characteristics of low noise and the like.

Description

No blade fan device
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.The noise that sends when the motor of this kind fan assembly and impeller work is easy to spread out of from relief opening by the inner passage of described nozzle, and its noise is subjected to very big influence than its application of ambassador.
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 noise lower is provided.
In order to achieve the above object, the technical solution used in the present invention is: the no blade fan device that is used to produce air stream, described fan assembly 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 assembly air outside is aspirated from the air-flow that described relief opening sprayed by described opening, it is characterized in that the part conduit wall of described at least inner passage is provided with the noise reduction layer.
Preferably, whole conduit walls of described inner passage are provided with the noise reduction layer.
Described noise reduction layer is made of sound-absorbing or soundproof material usually, described noise reduction layer can comprise foam layer, also can comprise the sponge material layer, also can comprise the glass wool material layer, also can comprise perforation flaggy and the quieter material layer that is attached on the described perforation flaggy, the noise reduction layer of all right other form.
The thickness of described noise reduction layer is usually between 2 millimeters to 25 millimeters, preferably between 2 to 10 millimeters.
Described nozzle limits an opening at least, also can limit a plurality of openings; 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 member comprises motor and by described motor-driven impeller; Described motor can be an AC induction motor, also can be dc brushless motor, can also be other motor.
The present invention has following good effect:
Because the conduit wall of the described inner passage of apparatus of the present invention is provided with the noise reduction layer, send out the noise that when making the work of motor and impeller and in the inner passage, be subjected to very big decay, be difficult to spread out of in a large number, so the noise around apparatus of the present invention reduces greatly from the relief opening of described nozzle.
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.
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 7 that is installed on the pedestal 1, in pedestal 1, hold the member (not drawing among the figure) that produces by the air-flow of nozzle 7, its member comprises motor and by motor-driven impeller, and with reference to figure 2, nozzle 7 has shell 2, nozzle 7 comprises inner passage 3 and relief opening 4, it is injected that air communication is crossed relief opening 4, nozzle 7 extends orthogonally basically about axis X and limits an opening 5, the fan assembly air outside is aspirated by the air-flow that is sprayed from relief opening 4 by opening 5, and the conduit wall of inner passage 3 is provided with noise reduction layer 6.
When this kind fan assembly uses, be positioned at the motor driving impeller work of pedestal 1, air can be drawn into from the intake grill (figure does not draw) that is arranged in pedestal 1 lower side, send in the inner passage 3 of nozzle 7 through acceleration or after boosting, and be deflated mouthful 4 ejections and flow out opening 5, being deflated mouthful 4 air-flows that sprayed from the air of ambient, external environment by opening 5 entrainments, the total air flow that air-flow that is ejected and the air-flow combination of being entrainmented are penetrated forward from nozzle 7 with generation, send out the noise that during simultaneously by motor and impeller work and be subjected to very big decay along the inner passage during 3 transmission, be difficult to spread out of in a large number, its noise is reduced greatly from the relief opening of described nozzle.
Although showed and described and thought preferred embodiments of the invention at present, apparent, those skilled in the art can carry out various changes and improvements, and does not deviate from the scope of the present invention that is limited by appended claims.
