- the present invention relates to portable appliances, such as fans, and, more particularly, to a portable fan capable of generating multiple independently positionable airflows.
- Portable fans are employed for a variety of purposes including air circulation and convective cooling. Such fans are relatively small and light, and are intended to be placed on the floor or countertop.
- the most frequently used forms of portable fans are the box fan and the pedestal fan which have an axial flow fan contained within an enclosure which is placed on the floor or mounted atop a pedestal.
- Fan enclosures have been pivotally mounted atop a pedestal so that the fan can be rotated about the vertical axis to adjust the direction of the airflow in the horizontal plane. Because many fans are placed on low surfaces, such as the floor, fans have been mounted about the midsection of the fan enclosure to a U-shaped base to form a yoke-like structure, thereby allowing the vertical direction of the airflow to be adjusted. This configuration allows the fan to be adjusted so that the airflow is directed at a specific target in the vertical plane.
- fans have been modified with a variety of air deflection devices.
- One solution is a motorized pivot which oscillates the fan to cyclically direct the airflow over a pre-defined range. This results in the airflow being directed at different targets in the same horizontal plane along the oscillating range. However, this may create undesirable air flow as the fan oscillates back and forth. If airflow is desired in only two locations, an oscillating fan may be used to create the breeze in those two locations, but will invariably also create an airflow at all points in between those two locations. Additionally, this oscillating configuration is limited to providing airflow generally at only two locations.
- a fan grill with angled veins can oscillate to change their deflection pattern, thus providing a similar result to oscillating the entire fan.
- a grill employing angled veins can be rotatably mounted to the fan enclosure, and the entire grill rotated to adjust the direction of the airflow.
- Such a rotatable grill is capable of directing the airflow to multiple points defined by the angle of the veins as the grill rotates, but it will also direct airflow at all point in between.
- the present invention relates to portable appliances, such as fans, and, more particularly, to a portable fan capable of generating multiple independently positionable airflows.
- One aspect of this invention provides an appliance assembly having a base support, a number of appliances, each contained within an appliance housing, and a frame coupled to the base support.
- Each appliance housing is rotatably mounted to an outer gimbal such that it is rotatable about a first axis, and each outer gimbal is mounted to the frame such that it is rotatable about a second axis.
- each appliance housing can be positioned independently with two degrees of freedom, and can be individually directed.
- the appliance contained within the appliance housing can include a blower fan.
- first and second axes are preferably perpendicular to each other.
- the first axis may be a vertical axis and the second axis may be a horizontal axis.

Abstract
Description
- The present invention relates to portable appliances, such as fans, and, more particularly, to a portable fan capable of generating multiple independently positionable airflows.
- Portable fans are employed for a variety of purposes including air circulation and convective cooling. Such fans are relatively small and light, and are intended to be placed on the floor or countertop. The most frequently used forms of portable fans are the box fan and the pedestal fan which have an axial flow fan contained within an enclosure which is placed on the floor or mounted atop a pedestal.
- Many improvements have been included in the design of portable fans to optimize or enhance their performance as coolers and air circulators. Specifically, many improvements have been made in controlling the volume and direction of airflow to suit the purpose for which the fan is employed.
- To enhance the convective cooling ability of fans, different mechanisms have been developed for directing the air-stream generated by a fan towards a particular target. Fan enclosures have been pivotally mounted atop a pedestal so that the fan can be rotated about the vertical axis to adjust the direction of the airflow in the horizontal plane. Because many fans are placed on low surfaces, such as the floor, fans have been mounted about the midsection of the fan enclosure to a U-shaped base to form a yoke-like structure, thereby allowing the vertical direction of the airflow to be adjusted. This configuration allows the fan to be adjusted so that the airflow is directed at a specific target in the vertical plane.
- Frequently, it is desirable to cool or direct airflow at more than one target in a room. To accomplish this, fans have been modified with a variety of air deflection devices. One solution is a motorized pivot which oscillates the fan to cyclically direct the airflow over a pre-defined range. This results in the airflow being directed at different targets in the same horizontal plane along the oscillating range. However, this may create undesirable air flow as the fan oscillates back and forth. If airflow is desired in only two locations, an oscillating fan may be used to create the breeze in those two locations, but will invariably also create an airflow at all points in between those two locations. Additionally, this oscillating configuration is limited to providing airflow generally at only two locations.
- Another solution is to use a fan grill with angled veins to deflect the airflow. The grill veins can oscillate to change their deflection pattern, thus providing a similar result to oscillating the entire fan. Alternatively, a grill employing angled veins can be rotatably mounted to the fan enclosure, and the entire grill rotated to adjust the direction of the airflow. Such a rotatable grill is capable of directing the airflow to multiple points defined by the angle of the veins as the grill rotates, but it will also direct airflow at all point in between.
- Accordingly, it would be desirable to provide a fan capable of directing airflow at multiple targets without inadvertently directing the airflow at all points between the targets. Additionally, it would be desirable to provide a fan capable of directing airflow at multiple targets that are not in the same horizontal and vertical plane.
- The present invention relates to portable appliances, such as fans, and, more particularly, to a portable fan capable of generating multiple independently positionable airflows.
- One aspect of this invention provides an appliance assembly having a base support, a number of appliances, each contained within an appliance housing, and a frame coupled to the base support. Each appliance housing is rotatably mounted to an outer gimbal such that it is rotatable about a first axis, and each outer gimbal is mounted to the frame such that it is rotatable about a second axis. Thus, each appliance housing can be positioned independently with two degrees of freedom, and can be individually directed.
- In a further aspect of this invention, the appliance contained within the appliance housing can include a blower fan.
- In a further aspect, the first and second axes are preferably perpendicular to each other. The first axis may be a vertical axis and the second axis may be a horizontal axis.
- The foregoing and other features of the present invention will be more readily apparent from the following detailed description and drawings of illustrative embodiments of the invention in which:
-
FIG. 1 is a front elevation view of a first embodiment of the invention; -
FIG. 2 is a right side elevation view of the first embodiment of the invention; -
FIG. 3 is a rear side elevation view of the first embodiment of the invention; -
FIG. 4 is a top plan view of the first embodiment of the invention; -
FIG. 5 is a bottom plan view of the first embodiment of the invention; -
FIG. 6 is a partial right side elevation view of the first embodiment of the invention; and -
FIG. 7 is a partial front elevation view of the first embodiment of the invention. - Referring now to the drawings, in one embodiment the present invention is directed to a
portable fan 10 having abase 60, aframe 20, a number ofblower fans 50, each enclosed by ablower housing 40. Eachblower housing 40 is rotatably mounted to anouter gimbal 30 atmount points 80 such that it is rotatable about a first axis. Eachouter gimbal 30 is rotatably mounted to theframe 20 atmount points 70 such that it is rotatable about a second axis that is non-parallel to the first axis. Theframe 20 is coupled to thebase 60 which provides support and keeps thefan 10 upright. - The rotational configuration of each
blower fan 50 is similar to a gimbal, in which the blower housing 40 is the inner gimbal. While a gimbal is most frequently associated with a set of gimbal rings, it is understood that a circular structure is not required and each structure defining a plane of rotation about an axis can take any shape. While the function of theouter gimbal 30 is not identical to that of an aeronautical or gyroscopic gimbal, because the structure provides a similar function, it is refereed to herein as theouter gimbal 30. - Each
blower fan 50 is independently positionable about the first and second axis defined bymount points fan 50 is rotatable about two non-parallel axes, the direction of the air flow can be positioned with two degrees of freedom. In a preferred embodiment, the first axis defined bymount points 80 is perpendicular to the second axis defined bymount points 70. This configuration provides easy control of the direction of the air flow from eachblower fan 50. - While the invention as shown in
FIG. 1 illustrates an embodiment of this invention having threeblower fans 50 substantially vertically aligned inframe 20, it should be understood by one of ordinary skill in the art that two ormore blower fans 50 can be used to achieve the desired objectives of this invention. Furthermore, theframe 20, theouter gimbals 30, andblower housings 40 can have a wide variety of configurations.FIGS. 2 and 4 illustrate that theframe 20 can arc or slant such thatblower fans 50 are staggered and are not required to be vertically aligned. Theframe 20 may extend horizontally, rather than vertically as illustrated in the figures, or it may be a square, rectangle, or other shape enclosing a array of blower fans (e.g., a three-by-three or two-by-four array). Theframe 20 can also have irregular or decorative shapes that providemount points 70 to which theouter gimbals 30 can be rotatably mounted. - The
frame 20 can also twist, such that, in the case of the embodiment illustrated in the figures, theframe 20 would look similar to a double-helix. Additionally,Frame 20 does not have to be an enclosed shape, but rather can be an open, for example a “U” structure or two vertical beams. - Similarly, the
outer gimbal 30 andblower housing 40, although illustrated in the figures as circular, do not have to be circular.Outer gimbal 30 andblower housing 40 can be any shape that allows them to be rotatably connected atmount points 70. Neither areouter gimbal 30 andblower housing 40 required to be the same, or even similar, shapes. - It should be noted that the shape of the
frame 20,outer gimbal 30 andblower housing 40 can be designed to limit the degree and direction of rotation about the first and second axis, and thus affect the directional range of the air flow generated by eachblower fan 50. The shape of each part can be designed such that it will be prevented from rotating in one direction about its axis, or the shapes can be designed to only allow a predetermined degree of rotation. Alternatively, the rotating mechanism of mount points 70 and 80 can be designed to limit the degree or direction of rotation. - In another aspect of the invention, if the shapes of the
blower housing 40,outer gimbal 30, orframe 20 are such that rotation about either the first or second axis causes interference between either theblower housing 40 and theouter gimbal 30 or theouter gimbal 30 and theframe 20, mount points 70 and 80 can be positioned away from the inner surface of theframe 20 orouter gimbal 30. Positioning the mount points 70 and 80 away from their respective inner surfaces provides a larger clearance distance between the rotating components, and thus prevents interference between the components and allows for a greater degree of rotation. According to this aspect, alternative shapes can be used while not limiting the direction or degree of rotation about the first or second axis. - The embodiment in the figures illustrates a parallel first axis and a parallel second axis for each
blower housing 40 andouter gimbal 30. It should be understood that the first and second axis of eachblower housing 40 andouter gimbal 30 do not need to be parallel to the first and second axis of eachother blower housing 40 andouter gimbal 30. Rather, each blower housing can have its own first and second axes. - In yet another aspect of this invention, each
blower fan 50 provides independent control of the blower speed. This may be useful for many situations. If there are two targets which are not equidistant from thefan 10, the closer target may not require the same velocity magnitude of air current, i.e., a person closer to the fan may be cold if the fan were run at the speed necessary to provide a comfortable level of air flow to someone further away. Similarly, the temperature or breeze which people find comfortable can differ greatly from one person to another. Thus, the speed control of eachblower fan 50 can be controlled from acontrol panel 90.Controls blower fans 50. Additionally, each control can provide multiple independent speeds. Alternatively, a single control (not shown) could be provided, thus providing control of all theblower fans 50 from a single device. - In another aspect of this invention each
blower housing 40 can include adetachable grill 140.Detachable grills 140 allow for ease of cleaning and can prevent dust buildup on the fan. - In a further aspect of the invention,
electrical wires 125 that supply power to each fan blower can be guided through the internal cavities of any of theframe 20, theouter gimbals 30, thebase 60, and theblower housings 40. Between components, theelectrical wires 125 can be guided through the mount points 70 and 80.FIGS. 6 and 7 illustrate theelectrical wires 125 entering theframe 20 and passing throughmount point 70,outer gimbal 30,mount point 80, and intoblower housing 40. Thus, the exposed electrical wiring is significantly limited, thereby increasing electrical safety, without decreasing the aesthetic appeal of the overall assembly. - To increase the portability of the
fan 10, thefan 10 can include ahandle 100. Thehandle 100 can be coupled to any part of thefan 10. Preferably, thehandle 100 is coupled to the fan so as to be positioned over the center of gravity of thefan 10. In the embodiment illustrated in the figures, thehandle 100 is positioned at the top and center of the fan. Similarly, another aspect of the present invention provides that theframe 20 can be detached from thebase 60, thereby enhancing the portability of thefan 10. - The embodiment of the present invention described herein is directed to a fan. However, it should be understood that the present invention may also be applicable to other appliances or products. For example, such products where it is desired to have multiple independently positional assemblies. Examples of such appliance assemblies include audio speakers, microphone arrays, lights, and heaters.
- While the invention has been shown by way of reference to a portable fan having a base, frame, a plurality of outer gimbals, and a plurality of blower housings, it will be understood by those skilled in the art that the present invention may be utilized in any portable device, such as a fan, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
