Description

Fan with deflector

The present invention is a ventilator having a flow guide associated with a means for venting.

Fans, which are very important devices in large plants or spaces, operate through the ventilator to assist in the circulation of air within the space.

The conventional fan is as shown in FIG. 1 , the two ends of the fan 10 are respectively an air inlet 11 and an air outlet 12 , and a fan 13 is fixedly disposed in the fan 10 , and the driving motor 13 is further disposed. The impeller 14 is driven to rotate to perform the action of sucking air, and when the air is sucked by the impeller 14, the continuous rotation of the impeller 14 causes the air to generate a rotating airflow, and the inside of the ventilator 10 is a space without any barrier, and the impeller 14 rotates. The generated swirling airflow will flow freely in the ventilator, which will cause turbulent flow of the rotating airflow. Once the airflow becomes turbulent, the ventilator 10 will generate great vibration and vibration noise. In view of this, the inventors have painstakingly studied and further conceived, and after many trials and developments, finally invented a ventilator with a flow guiding member.

The invention provides a ventilator with a flow guiding member, the main purpose of which is to reduce vibration and noise, and to guide the airflow to discharge the airflow stably and regularly, thereby improving the exhaust efficiency.

In order to achieve the foregoing object, the present invention provides a ventilator having a flow guiding member for guiding a flow of air with a flow guiding member before the airflow is discharged, thereby making the discharged airflow a stable and regular airflow, and reducing the conventional use. Noise and vibration generated by turbulence, and at the same time can improve exhaust efficiency.

In order to enable your review committee to have a better understanding and understanding of the purpose, features and effects of the present invention, please refer to the following [detailed description of the drawings] as follows: The preferred implementation of the ventilator with the flow guiding member of the present invention For example, as shown in the second to fourth embodiments, the fan body 20 has a hollow cylinder structure and is connected by a first body segment 21 and a second body segment 22, and the two ends of the fan body 20 are respectively open. The air inlet 211 and the air outlet 221 are located in the first body segment 21, and the air outlet 221 is located in the second body segment 22, and the second body segment 22 is gradually expanded by the air outlet 221 The two support frames 30 are respectively fixed to the outer circumferences of the first body portion 21 and the second body portion 22 of the fan body 20 to support the fan body 20; a driving motor 40 is fixed to the fan by a plurality of connecting plates 41. In the main body 20, one end of the connecting plate 41 is fixed to the inner surface of the fan body 20, and the other end is fixed to the outer peripheral surface of the driving motor 40. An impeller 50 is connected to the driving motor 40, and the impeller 50 is driven by the driving motor. 40 driving rotation, and the impeller 50 is located at the driving motor 40 and the suction Between the 211 and facing the air inlet 211; and the plurality of flow guiding members 60, in this embodiment, three flow guiding members 60 are disposed, respectively having a first end 61 and a second end 62, and the first end The first end 62 and the second side 62 are connected to each other by a fixed side edge 63 and a free side edge 64. The flow guiding members 60 are respectively fixed to the fan body 20 by the fixing side edge 63. The surface of the flow guiding member 60 is fixed between the driving motor 40 and the air outlet 221, and the flow guiding members 60 are disposed at equal intervals in the second body portion 22, and the first end of each flow guiding member 60 61 is directed toward the driving motor 40, and the second end 62 of each of the flow guiding members 60 extends toward the air outlet 221 of the fan body 20. The flow guiding member 60 of the embodiment is a flat sheet-like structure, and the diversion flows The fixing side edge 63 of the member 60 is connected to the fan body 20 by a plurality of fixing members 70. The fixing member 70 is an L-shaped structure formed by connecting a flow guiding member connecting portion 71 and a fan body connecting portion 72. Each of the flow guiding members 60 of the embodiment is connected to the fan body by two fixing members 70, and the flow guiding member connecting portion 71 of each fixing member 70 is connected to the flow guiding members 60, and each fan is connected. Connected to the connecting portion 72 of each fan main body 20, and two solid-body connection portion of the fan guide member 60 of each support member 70 of the connector 72 extends in the opposite direction.

The above is the structural relationship of the ventilator having the flow guiding member of the present invention. In use, the driving motor 40 drives the impeller 50 to rotate and sucks air from the air inlet 211 of the fan body 20, and the air sucked into the fan body 20 is subjected to the air. The impeller 50 rotates to generate an air flow and flows to the air outlet 221, and before the airflow is to be discharged from the air outlet 221, the flow guiding members 60 are first passed through, and the flow guiding members 60 are equiangularly disposed on the first In the two sections 22, the airflow is shunted by the flow guiding members 60, and the airflow is guided to the air outlets 221 by the air guiding members 60. The airflow is guided by the flow guiding members 60. Discharge, so that it can be a stable and regular airflow discharge, which can greatly reduce the noise and vibration generated by the turbulent flow of the conventional technology; and because the second body section 22 is gradually expanded by the air outlet 221, and each flow guide 60 is equiangularly arranged and the second end 62 extends toward the air outlet 221, so that the flow guiding members 60 have a concentrated effect on the air outlet 221, thereby stabilizing due to the guiding concentration of the flow guiding members 60. Concentrate the air to improve the efficiency of exhaust.

In addition, referring to another embodiment shown in FIGS. 5-7, the main components and structural relationships are the same, and the difference lies in the shape of the flow guiding members 60. The flow guiding members 60 are in addition to the above embodiments. In addition to the straight sheet shape, it can be formed into a curved sheet shape having a curved curvature, and the respective flow guiding members 60 are in a state in which the first end 61 is bent, whereby the same purpose as described above can be achieved in the same manner.
