The present invention relates generally to mobile fan assemblies, and, more particularly, relates to mobile fan assemblies operably configured to generate an air velocity gradient and circulate air in an ambient environment.
Whether located in an inside or outside environment, many users desire to control the ambient air temperature or airflow surrounding the users. Many known climate controlling devices and methods available to do so, however, are impracticable or inefficient for users located in mobile or remote environments. For example, some known devices and methods include employing the use of a rotatable fan blade that may or may not be encapsulated in a housing. Many, if not most, of these devices, however, are not designed or configured to create an evaporative cooling environment or control the directional flow of air in an ambient environment. The climate controlling devices that are configured to control directional flow of air or other gasses do so in an inefficient and/or impracticable manner.
One such climate controlling device for example, embodied in U.S. Pat. No. 6,321,034 (Nov. 20, 2001) issued to The Holmes Group, Inc., discloses the use of two blowers disposed in respective housings that are operably configured to rotate with respect to one another. The rotation of the two blower housings distributes flow of air in an ambient environment, but is limited in speed to effectuate flow and otherwise requires motors, bearings and other components required to effectuate the rotation (thereby making these devices more prone to failure, expensive, and heavier).
Therefore, a need exists to overcome the problems with the prior art as discussed above.
The invention provides a mobile climate control assembly and method of use that overcomes the hereinafore-mentioned disadvantages of the heretofore-known devices and methods of this general type and that enables computer-controlled airflow without any rotation of a fan housing.
With the foregoing and other objects in view, there is provided, in accordance with the invention, a method of utilizing a mobile climate control assembly to selectively generate air flow across an angular range and at various velocities that includes the steps of providing a first fan blower-wheel assembly retained in at least one housing (i.e., one or more), having a wheel member operably coupled to at least one motor and with a plurality of wheel blades disposed circumferentially around the wheel member and operably configured to rotate 360° around an axis of rotation, and having an air deflector wall surrounding a partial circumference of the wheel member of the first fan blower-wheel assembly and with a front end portion configured to direct air generated from the wheel member of the first fan blower-wheel assembly outwardly from the at least one housing and providing a second fan blower-wheel assembly retained in the least one housing, having a wheel member operably coupled to the at least one motor and with a plurality of wheel blades disposed circumferentially around the wheel member of the second fan blower-wheel assembly and operably configured to rotate 360° around an axis of rotation, having an air deflector wall surrounding a partial circumference of the wheel member of the second fan blower-wheel assembly and with a front end portion configured to direct air generated from the wheel member of the second fan blower-wheel assembly outwardly from the at least one housing, wherein the at least one motor of the first and second fan blower-wheel assemblies communicatively coupled to an electronic controller.

The present invention provides a novel and efficient mobile climate control assembly and method of use that utilizes computer-controlled wheel blower assemblies to selectively generate air flow across a wide angular range and at various velocities with little to no other moving parts. Embodiments of the invention provide an assembly and method to effectively and efficiently increase or decrease the ambient surrounding air for the comfort of users. As such, embodiments of the present invention generate oscillation of airflow using air convergence and vectoring employ the use of at least two crossflow or tangential fans disposed at angles with respect to each other. To effectuate the same, an electronic controller is operably coupled to motors on each of the fans, thereby offering users unlimited patterns of oscillated air flow up to approximately 160°.

The housing 102 includes an upper end 108, a lower end 1000 opposing the upper end 106 of the housing 102, a housing length 502 separating the upper and lower ends 108, 1000, a front face 500, and a rear face 600 opposing the front face 500. The housing 102 is preferably constructed of a waterproof, durable, substantially rigid, and lightweight material, e.g., ABS plastic or aluminum. The housing length or height 502 may be approximately 65-96 inches, wherein the width (i.e., side-to-side) and depth (rear face 600 to front face 500) may be approximately 20-25 inches and 16-25 inches, respectively. Other dimensions outside of those ranges are contemplated, however. The shape, size, and configuration of the housing 102, along with the configuration of air inlets and exists, generates a very small footprint operably configured to beneficially fit in rooms, corners, and areas of various sizes and dimensions. To that end, the depth of the housing 102 may be tapered in some embodiments to fit within room corners.

The top end 1308 of the wheel members 1600,1602 may be rotationally coupled to housing 102, including the cover 106, using, for example, a bearing enabling the reduction of frictional losses. In other embodiments, the top end 1308 of the wheel members 1600,1602 may be structurally unattached and uncoupled to the housing 102. One exemplary operably coupled relationship between the fan motor and wheel member includes a shaft sized and shape to be inserted into a shaft channel defined on the bottom end 1310 of the wheel member. The coupling configuration between the fan motor and wheel member may be a tongue-and-groove configuration or other configuration enabling rotation of the wheel member.
