Description

  The present invention relates to a tower type electric fan, and more particularly to a tower type electric fan capable of blowing air in all directions of 360 degrees.

  The so-called tower-type fan includes an axial-flow electric fan, and the axial-flow blades are arranged in a housing in an upright manner and the appearance looks like a tower, so it is called a tower-type fan. ing.

  The upright tower type fan has a wide exhaust outlet, so the air blowing area is large, but the wind power is not sufficient, and there is a problem that noise during operation is large, which is not ideal. In addition, most of the conventional tower type fans with swing function are designed so that the main body reciprocally swings within a specific angle. The wind only reaches the users within the angle range, and the conventional tower-type fan was not ideal.

  A main problem of the present invention is to provide a tower type fan that blows air 360 degrees in all directions radially outward from a fan.

Thus, as a result of repeated investigations to solve the above problems, the present inventor has paid attention to the fact that the above problems can be solved by a tower-type fan capable of blowing air in all directions of 360 degrees as described below. I came to the idea.
Thus, according to the present invention, a tower-type fan that is capable of blowing air in all directions of 360 degrees including a housing and a fan group,
The fan group includes a plurality of blades mounted on a rotating shaft,
The housing has a plurality of air inlets and air outlets,
The air outlet is formed around the housing;
Above the blades, a flow guide portion is formed,
The flow guide portion has an arcuate wall;
The arc-shaped wall is formed in an arc shape upward and outward from a position adjacent to the rotation axis to the exhaust port, and an air flow is guided by the arc-shaped wall, and radially from the exhaust port to the periphery. It is possible to provide a tower type fan capable of blowing air in all directions of 360 degrees, which is characterized by being blown.

  The present invention is configured as described above and can blow air in all directions at 360 degrees. Further, it is possible to blow air far away.

FIG. 1 is a perspective view showing a tower type fan that blows air in all directions of 360 degrees according to an embodiment of the present invention. FIG. 2 is a cross-sectional view showing a tower type fan that blows air in all directions of 360 degrees according to an embodiment of the present invention. FIG. 3 is a schematic diagram showing an air flow direction of a tower type fan that blows air in all directions of 360 degrees according to an embodiment of the present invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited thereby.

  Please refer to FIG. 1 and FIG. As shown in FIGS. 1 and 2, the tower-type fan that blows air in all directions of 360 degrees according to an embodiment of the present invention includes at least a housing 10 and a fan group 20. A fan group 20 is disposed in the housing 10. As shown in FIGS. 1 and 2, the fan group 20 includes a plurality of blades 21 attached on a rotating shaft 22. The blade 21 is rotated by being connected to a drive motor 23. The housing 10 has an intake port 11 and an exhaust port 12 corresponding to the number of fans. The air inlet 11 and the air outlet 12 communicate with the inside and outside of the housing 10. The air outlet 12 is formed around the housing at 360 degrees.

  Please refer to FIG. FIG. 2 is a cross-sectional view showing a tower type fan that blows air in all directions of 360 degrees according to an embodiment of the present invention. The intake port 11 is formed at a location close to the lower side of the blade 21. A flow guide portion 13 is formed above the blade 21. The flow guide portion 13 has an inverted conical shape and has an area covering the airflow range of the fan. The flow guide portion 13 has an arcuate wall 131. The arc-shaped wall 131 is formed in an arc shape upward and outward from a location adjacent to the rotation shaft 22 to the exhaust port 12. A bearing 24 is provided between the rotating shaft 22 and the flow guide portion 13 in order to improve the operational stability. Of course, the entire drive function may be controlled by the operation panel 30 and the control circuit 40 without changing the main architecture of the present invention.

  Please refer to FIG. As shown in FIG. 3, after actually assembling the structure of the present invention, the wind generated by the operation of the blade 21 of the present invention is sent upward, but the wind is guided by the arcuate wall 131 of the flow guide section 13, The air is blown radially outward from the exhaust port 12. Therefore, the air can be blown around the electric fan and blown to the user, and the air can be blown relatively far because it has at least one air outlet. In this way, the electric fan can blow air in all directions at 360 degrees.

  As can be seen from the above, the tower-type fan that blows air in all directions of 360 degrees according to the present invention is easy to manufacture, and it blows air in all directions of 360 degrees without the complicated swing mechanism of the prior art. Therefore, it is more economical than conventional tower fans.

The preferred embodiments of the present invention have been disclosed as described above so that those skilled in the art can understand them, but these do not limit the present invention in any way. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the utility model registration claim of the present invention should be broadly interpreted including such changes and modifications.
