  • The primary purpose of the present invention is to provide a vertical tower fan, which includes multiple air outlets arranged at different elevations for output air streams in different directions. It is another object of the present invention to provide a vertical tower fan, which allows adjustment of the direction of each air outlet individually.
  • To achieve these and other objects of the present invention, the vertical tower fan comprises a frame structure, a fan module, and multiple housing members. The frame structure comprises a plurality of posts, and a plurality of partition plates fixedly fastened to the posts at different elevations and defining a plurality of vertically spaced fan spaces. The fan module comprises a fan motor, a fan shaft vertically inserted through the partition plates and rotatable by the fan motor, and a plurality of fan blades respectively suspending in the fan spaces and affixed to the fan shaft for rotation with the fan shaft. The housing members are respectively sleeved onto the posts of the frame structure and surrounding the fan spaces and the fan blades of the fan module and individually rotatable relative to the frame structure. Each housing member comprises an air inlet, an air outlet, and a grill provided over the air outlet.
  • The vertical tower fan comprises further includes a base that supports the frame structure. The frame structure is rotatable relative to the base. Further, each housing member comprises a wind baffle disposed at one side of the respective air outlet for guiding generated air stream out of the air outlet. The grill of each housing member is comprised of a plurality of inclination angle-adjustable louvers.
  • Further, each partition plate comprises a series of teeth arranged on the bottom wall thereof, and each housing member comprises a springy protrusion engageable with the teeth of one housing member.
  • The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
  • Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 illustrates the outer appearance of an adjustable multi-outlet vertical tower fan in accordance with the present invention.
  • FIG. 2 is an exploded view of the adjustable multi-outlet vertical tower fan in accordance with the present invention.
  • FIG. 3 is an elevational view of the present invention, showing the frame structure of the adjustable multi-outlet vertical tower fan.
  • FIG. 4 is an elevational view of a part of the present invention, showing the structure of the fan motor.
  • FIG. 5 is a sectional plain view of a part of the present invention, showing an engagement status between the top protrusion of one housing member and the associated partition plate.
    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
  • Referring to FIG. 1, an adjustable multi-outlet fan 1 in accordance with the present invention is a vertical tower fan comprising a plurality of housing members 2 rotatably arranged at different elevations. Each housing member 2 has an air inlet 23 and an air outlet 21. Air inlet and output grills 22 are respectively provided over the air inlet 23 and the air outlet 21. Each grill 22 is comprised of a plurality of inclination angle-adjustable louvers. The user can manually rotate each housing member 2 to adjust the direction of the air inlet 23 and air outlet 21 of the respective housing member 2. The adjustable multi-outlet fan 1 further comprises a base 14 disposed at a bottom side for positioning on a flat floor surface stably, an operation panel 12 disposed at a top side for operation by a person directly by hand to control the operation of the internal fan module (not shown), and a remote control sensor 13 for receiving control signals from an external remote controller and driving the internal fan module to operate subject to the control of the external remote controller. Further, a person can control a driving mechanism (not shown) in the adjustable multi-outlet fan 1 to rotate the body of the adjustable multi-outlet fan 1 on the base 14 alternatively back and forth within a predetermined angle by means of the operation panel 12 or the remote controller.
  • Referring to FIGS. 2˜4, the adjustable multi-outlet fan 1 further includes a frame structure formed of multiple posts 11 and circular partition plates 15, and a fan module 3. The partition plates 15 are horizontally fixedly fastened to the posts 11 at different elevations. The fan module 3 comprises a fan motor 31 fixedly mounted on the base 14, a fan shaft 32 vertically inserted through (the center opening of each of) the partition plates 15 fixedly connected to the rotor of the fan motor 31, and a plurality of fan blades 33 affixed to the fan shaft 32 at different elevations corresponding to the space defined between each two adjacent partition plates 15.
  • Referring to FIG. 5 and FIG. 2 again, the housing members 2 are sleeved onto the posts 11 and respectively rotatably supported on the partition plates 15. Each partition plate 15 has a series of teeth 16 protruded from the bottom wall and arranged along the border. Each housing member 2 has a springy top protrusion 25 engaged with the teeth 16 of one associating partition plate 15, and a wind baffle 24 disposed at one side of the air outlet 21 for guiding generated air stream out of the air outlet 21. When rotating one housing member 2 relative to the posts 11, the top protrusion 25 is forced to deform temporarily and moved over the teeth 16 of the associating partition plate 15. When the user released the hand, the top protrusion 25 immediately returns to its former shape and is kept in engagement with the teeth 16 of the associating partition plate 15 again. Therefore, the user can directly rotate each housing member 2 to adjust the direction of the respective air outlet 21.
  • It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
  • While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
