Description

BACKGROUND OF THE INVENTIONS

1. Field of the Inventions

The present application relates generally to systems, devices and methods for moving air that are particularly suitable for creating air temperature de-stratification within a room, building, or other structure.

2. Description of the Related Art

The rise of warm air and the sinking of cold air can create significant variation in air temperatures between the ceiling and floor of buildings with conventional heating, ventilation and air conditioning systems. Air temperature stratification is particularly problematic in any spaces with any ceilings such as warehouses, gymnasiums, offices, auditoriums, hangers, commercial buildings, offices, residences with cathedral ceilings, agricultural buildings, and other structures, and can significantly increase heating and air conditioning costs. Structures with both low and high ceiling rooms can often have stagnant or dead air, as well, which can further lead to air temperature stratification problems.

One proposed solution to air temperature stratification is a ceiling fan. Ceiling fans are relatively large rotary fans, with a plurality of blades, mounted near the ceiling. The blades of a ceiling fan have a flat or airfoil shape. The blades have a lift component that pushes air upwards or downwards, depending on the direction of rotation, and a drag component that pushes the air tangentially. The drag component causes tangential or centrifugal flow so that the air being pushed diverges or spreads out. Conventional ceiling fans are generally ineffective as an air de-stratification device in relatively high ceiling rooms because the air pushed by conventional ceiling fans is not maintained in a columnar pattern from the ceiling to the floor, and often disperses or diffuses well above the floor.

Another proposed solution to air temperature stratification is a fan connected to a vertical tube that extends substantially from the ceiling to the floor. The fan can be mounted near the ceiling, near the floor or in between. This type of device can push cooler air up from the floor to the ceiling or warmer air down from the ceiling to the floor. Such devices, when located away from the walls in an open space in a building, interfere with floor space use and are not aesthetically pleasing. When confined to locations only along the walls of an open space, such devices may not effectively circulate air near the center of the open space. Examples of fans connected to vertical tubes are disclosed in U.S. Pat. No. 3,827,342 to Hughes, and U.S. Pat. No. 3,973,479 to Whiteley.

A more practical solution is a device, for example, with a rotary fan that minimizes a rotary component of an air flow while maximizing axial air flow quantity and velocity, thereby providing a column of air that flows from a high ceiling to a floor in a columnar pattern with minimal lateral dispersion without a physical transporting tube. Examples of this type of device are described in U.S. patent application Ser. No. 12/130,909, filed May 30, 2008, and U.S. patent application Ser. No. 12/724,799, filed Mar. 16, 2010, each of which is incorporated in its entirety by reference herein.

SUMMARY OF THE INVENTION

An aspect of at least one of the embodiments disclosed herein includes the realization that it would be beneficial to have a columnar air moving device that has a low vertical profile, such that the device can fit into the ceiling structure of a building without extending below the ceiling to an extent that it is distracting or obstructive, and can fit within two generally horizontal ceiling structures.

Another aspect of at least one of the embodiments disclosed herein includes the realization that it would be beneficial to have a columnar air moving device that is designed specifically to fit within a ceiling grid structure, such that it is easy to install, remove, and replace the columnar air moving device if required.

Another aspect of at least one of the embodiments disclosed herein includes the realization that rooms within a building often have support beams or other structures that can make it difficult to install a columnar air moving device (or devices) within the room and direct the air to a pre-defined area.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to FIGS. 1-5, an air moving device 10 can comprise a housing member 12. The housing member 12 can form an outer shell of the air moving device 10, and can at least partially enclose an interior space within the air moving device 10. The housing member 12 can be formed from one or more sections. For example, the housing member 12 can comprise an upper housing section 14, and a lower housing section 16. In some embodiments the upper and lower housing sections 14, 16 can be attached to one another through use of fasteners, adhesive, or other structure. In some embodiments the upper housing section 14 can comprise a dome shape. In some embodiments, the upper housing section 14 can comprise a generally round, circumferentially-shaped structure, and the lower housing section 16 can comprise a generally rectangular-shaped structure. In some embodiments the lower housing section 16 can form an outer periphery of the housing member 12. In some embodiments, the dome shaped upper housing section 14 and rectangular-shaped lower housing section 16 can be integrally formed as a single piece.

The housing member 12 can include a top surface 18. In some embodiments the top surface 18 can include or be attached to a support member. The support member can include, for example, a ring-shaped structure (e.g. an eye-bolt as illustrated in FIG. 10). In some embodiments, the housing member 12 can be hung by the support member, and/or can be attached to another structure with the support member. In some embodiments, and as described further below, the top surface 18, and/or any support member formed from or attached to top surface 18, can be configured to rest between two generally horizontal ceiling structures within an air moving system.

With reference to FIGS. 1-5, the housing member 12 can comprise a ceiling support structure 20. The ceiling support structure 20 can form part of the lower housing section 16. The ceiling support structure 20 can be a separate component attached to the housing member 12. In some embodiments, the ceiling support structure 20 can comprise a lip member. The ceiling support structure 20 can include an outer peripheral edge 22. The outer peripheral edge 22 of the ceiling support structure 20 can form a generally rectangular structure around the air moving device 10, though other shapes are also possible. The outer peripheral edge 22 can form an outer peripheral edge of the air moving device 10. The ceiling support structure 20 can also include a lower surface 24. At least a portion of the lower surface 24 can be configured to rest upon one or more ceiling structures when the air moving device 10 is mounted in a ceiling. The lower surface 24 can be a generally flat surface, though other surfaces are also possible.

With continued reference to FIGS. 1-5, the ceiling support structure 20 can include one or more seismic connect tabs 26. The seismic connect tabs 26 can be used to connect the air moving device 10 to one or more ceiling structures in a ceiling. The seismic connect tabs 26 can permit movement of the air moving device 10 relative to one or more ceiling structures during the event of an earthquake or other similar event.

With continued reference to FIGS. 1-5 and 9, the housing member 12 can comprise at least one air vent 28. The air vent or vents 28 can be configured to direct a volume of air into the interior space of the air moving device 10. For example, the housing member 12 can comprise a plurality of air vents 28 in the lower housing section 16. The plurality of air vents 28 can be spaced directly below the ceiling support structure 20. In some embodiments the air vents 28 can be separated by air vent guides 30. The air vent guides 30 can comprise ring-like structures extending generally circumferentially along the lower housing section 16. In some embodiments the outer diameters of the air vent guides 30 can decrease moving downwardly away from the ceiling support structure 20.

The air vent guides 30 can be connected to air vent face plates 32. The air vent face plates 32 can be spaced circumferentially around the lower housing section 16. The air vent face plates 32, in conjunction with the air vent guides 30, can be configured to direct a volume of air inwardly through the air vents 28, and up into the interior space defined by the housing member 12. The air vent face plates 32 can be solid structures that divide the air vents 28 into sections or portions.

With continued reference to FIGS. 1-4, the air moving device 10 can comprise a nozzle 34. The nozzle 34 can communicate with and extend downwardly from the housing member 12. The nozzle 34 can comprise a structure for directing a volume of air out of the air moving device 10. For example, the nozzle 34 can comprise a structure for directing a volume of air out of the air moving device 10 that has previously entered through the plurality of air vents 28. In some embodiments, the nozzle 34 is attached to the housing member 12.

With reference to FIGS. 6 and 9, the air moving device 10 can comprise a rotary fan assembly 36 mounted within the interior space. The rotary fan assembly 36 can comprise an impeller 38 and a plurality of blades 40. The rotary fan assembly 36 can be configured to direct a volume of air that has entered through the plurality of air vents 28 downwardly into the nozzle 34. The rotary fan assembly 36 can push, or force, a volume of air downwardly within the interior space of the air moving device 10. The rotary fan assembly 36 can comprise a motor. The rotary fan assembly 36 can comprise at least one electrical component. The rotary fan assembly 36 can be mounted generally above the plurality of air vents 28, such that the volume of air entering the plurality of air vents 28 is required to travel upwardly within the interior space of the air moving device 10 before it can enter the rotary fan assembly 36. In some embodiments, the rotary fan assembly 36 can be mounted to the lower housing section 16. The nozzle 34 can communicate with and extend downwardly from the rotary fan assembly 36. In some embodiments, the nozzle 34 is attached to the rotary fan assembly 36.

With continued reference to FIGS. 7-9, the air moving device 10 can include additional structures that facilitate de-stratification. For example, the nozzle 34 of the air moving device 10 can comprise at least one stator vane 42. The stator vanes 42 can be positioned equidistantly in a circumferential pattern within the nozzle 34. The stator vanes 46 can further direct the volume of air that has entered through the plurality of air vents 28 and has moved into the rotary fan assembly 36 and further down into the nozzle 34. For example, the stator vanes 42 can be used to straighten a volume of air within the nozzle 34. The stator vanes 42 can be used to force a volume of air to move in a generally columnar direction downwardly towards the floor of a building or other structure, with minimal lateral dispersion, similar to the devices described for example in U.S. patent Ser. No. 12/130,909, and U.S. patent application Ser. No. 12/724,799, each of which is incorporated in its entirety by reference herein. In some embodiments, the nozzle 34 can have no stator vanes 42.

With reference to FIG. 9, in some embodiments the stator vanes 42 can comprise one or more cutouts 44. The cutouts 44 can create space for insertion, for example, of an ionization cell (i.e. a PHI cell). The ionization cell can be used to increase the air quality. The cutouts 44 can form a void or opening in the middle of the nozzle 34, and the ionization cell (not shown) can be inserted into the opening for example during manufacturing. The volume of air moving through the air moving device 10 can run past, alongside, or through the ionization cell, and be cleaned.

With continued reference to FIGS. 3 and 9, in some embodiments the air moving device 10 can comprise a longitudinal axis L that runs through a middle of the air moving device 10. The housing member 12 can comprise an opening 46 for insertion of the nozzle 34, and the nozzle 34 can comprise at least one spherical surface 48 configured to fit within the opening 46 such that the nozzle 34 can be adjusted angularly relative to the longitudinal axis L. For example, the nozzle 34 can rest within the opening 46, such that the spherical surface 48 contacts the housing member 12, and is not rigidly attached to the housing member 12. In this manner, the housing member 12 can act as a gimbol, allowing pivoted rotational movement of the nozzle 34. The nozzle 34 can be moved at an angle or angles relative the longitudinal axis L, so as to direct the column of air leaving the air moving device 10 towards different directions. In some embodiments, the nozzle 34 can be vertical or angled at least 10 degrees relative to the longitudinal axis L in one or more directions. In some embodiments, the nozzle 34 can be angled at least 15 degrees relative to the longitudinal axis L in one or more directions. In some embodiments the nozzle 30 can be angled at least 20 degrees relative to the longitudinal axis L in one or more directions. In some embodiments, the nozzle 34 can be angled at least 45 degrees relative to the longitudinal axis L in one or more directions. In some embodiments the nozzle 34 can self-lock in place once it has been repositioned. For example, the weight of the nozzle 34, and/or the coefficients of friction of the materials used to create the nozzle 34 and housing member 12, can be such that the nozzle 34 can frictionally lock itself in place in various positions. In some embodiments, the nozzle 34 and/or housing member 12 can incorporate one or more mechanical or other types of mechanisms for locking the nozzle 34 in place once it has been repositioned.

While use of a spherical surface on the nozzle 30 is described and illustrated, other types of mechanisms could also be used to permit relative movement of the nozzle 30, and/or to allow the nozzle 30 to be locked in place in various angular positions.

In some buildings, there are support beams, ductwork, conduit, wiring, or other structures that would otherwise block the flow of a columnar air moving device, or make it difficult for an air moving device to direct air to a desired area. Therefore, at least one benefit achieved by having a nozzle 34 that can be repositioned is the fact that the air moving device 10 can be positioned in or below a ceiling, some distance away from an area in need of de-stratification, and the nozzle 34 can simply be adjusted so as to direct the column of air towards that area of need.

With continued reference to FIG. 9, the air moving device 10 can further comprise at least one anti-swirl member 50. The anti-swirl member 50 can be located within the interior space of the air moving device 10 formed by the housing member 12. In some embodiments, one or more anti-swirl members 50 can be attached to an interior surface of the upper housing section 14. The anti-swirl members 50 can be used to slow down and/or inhibit swirling of air within the interior space located above the rotary fan assembly 36. For example air can be swirling turbulently, at a top of the air moving device 10 after it has entered the device. The anti-swirl members 50 can extend into the space where the air is moving and slow the air down, and/or redirect the air, so that the air is directed more linearly down towards the nozzle 34. It can be desirable to slow down and/or inhibit swirling of air, such that the air can be directed more easily in a generally columnar pattern down through the nozzle 34 with greater ease and efficiency. The anti-swirl members 50 can be used to inhibit turbulence within the air moving device 10. In some embodiments, the anti-swirl members 50 can comprise one or more ribs. The ribs can extend along an inside surface of the housing member 12. The ribs can inhibit a swirling pattern of air.

In some embodiments, the air moving device 10 can be a self-contained unit, not connected to any ductwork, tubing, or other structure within a room or building. The air moving device 10 can be a stand-alone de-stratification device, configured to de-stratify air within a given space.

In some embodiments, the air moving device 10 can have an overall height (extending from the top of the housing member 12 to the bottom of the nozzle 34) that ranges from between approximately one foot to four feet, though other ranges are also possible. For example, in some embodiments the air moving device 10 can have an overall height that ranges from approximately one feet to three feet. In some embodiments the housing member 12 can have an overall outside diameter that ranges from approximately 8 inches to 30 inches, though other ranges are also possible. For example, in some embodiments the housing member 12 can have an overall outside diameter that ranges from approximately 12 inches to 24 inches. In some embodiments, the nozzle 30 can have an outside diameter that ranges between approximately five inches to twelve inches, though other ranges are possible. For example, in some embodiments the nozzle 30 can have an outside diameter that ranges from between approximately eight to ten inches. In some embodiments the air moving device 10 can have a motor with an overall power that ranges between approximately 720 and 760 watts, though other ranges are possible. In some embodiments the air moving device 10 can have a motor with an overall power that can vary from approximately 10 to 740 watts.

With reference to FIGS. 11 and 12, an air moving system 110 can comprise a first ceiling level 112 forming a base portion of a ceiling in a building or room. The first ceiling level 112 can comprise a plurality of grid cells 114. Each of the grid cells 114 can be bordered by at least one grid cell periphery structure 116. In some embodiments, at least a portion of the grid cell periphery structure 116 can have a t-shaped cross section. In some embodiments, the grid cells 114 can comprise an open space between the grid cell periphery structures 116. The grid cells 114 can be generally rectangular. In some embodiments the grid cells 114 are approximately 24 inches by 24 inches in size, though other sizes and shapes are also possible.

In some embodiments, the ceiling support structure 20 can be configured to rest on or be attached to one or more grid cell periphery structures 116. For example, in some embodiments the air moving device 10 can rest on two grid cell periphery structures 116. In some embodiments the air moving device can rest on four grid cell periphery structures 116. In some embodiments, the grid cell periphery structures 16 can be configured to support the ceiling support structure 20 and air moving device 10. In some embodiments, the grid cell periphery structures 16 are attached to the ceiling support structure 20, for example with at least one fastener. In some embodiments the grid cells 114 can have generally the same outer peripheral profile as the ceiling support structure 20, such that the ceiling support structure 20 is configured to rest on the surrounding grid cell periphery structures 116, and the air moving device 10 fits easily within a single grid cell 114. As described above, seismic connect tabs 26 can be used to provide further connection.

With reference to FIG. 12, the air moving system 110 can further comprise a second ceiling level 118. The second ceiling level 118 can be separated from the first ceiling level 112 by a height H. In some embodiments, both the first and second ceiling levels 112, 118 are generally horizontal structures. In some embodiments the first and second ceiling levels 112, 118 are parallel to one another. As described above, and as illustrated in FIG. 12, an air moving device 10 can be configured to fit within the air moving system 10 such that the top surface 18 is located between the first and second ceiling levels 112, 118. The low vertical profile of the air moving device 10, and in particular the upper housing section 14, advantageously enables the air moving device to fit within this space between the first and second ceiling levels 112, 118.

Overall, the air moving system 110 can permit multiple air moving devices 10 to be supported by or attached to the grid cell periphery structures 116. The air moving devices 10 can be removed, replaced, or moved in the air moving system 110. If required, and as described above, the nozzles 34 can be moved, pivoted, and/or rotated, depending on where it is desired to direct air within a building or room having an air moving system 110.

In some embodiments, the air moving device system 110 can comprise a solid ceiling structure (e.g. a drywall structure). A portion of the ceiling structure can be removed to make room for the air moving device 10. For example, a portion of drywall or other material can be cut out, and the air moving device 10 can be supported by and/or mounted to the ceiling structure in the air moving device system 110, with at least a portion of the air moving device 10 located within the cut-out portion.

Although these inventions have been disclosed in the context of certain preferred embodiments and examples, it will be understood by those skilled in the art that the present inventions extend beyond the specifically disclosed embodiments to other alternative embodiments and/or uses of the inventions and obvious modifications and equivalents thereof.
