The present invention relates to air diffusers and, more particularly, to a decorative air diffuser with a modern linear slot style, for replacement in residential applications.
The present invention addresses the problem of limited options currently available for decorative residential air grilles and/or diffusers, that typically leave visible the unfinished construction looks of ductwork/connection behind the grille face and are difficult to remove and/or replace for cleaning. For example, once removed from the original mounting holes, it is often difficult to remount them to those same holes and achieve the same installed appearance without additional renovation work.
Current options have a louvered face style, that leaves the unfinished construction visible behind the face. As mentioned, limited options are available, and still look similar in appearance. Removing the grille face is typically a messy project and is often discouraging for the common homeowner not proficient on a ladder with tools. The market is looking for more decorative options, with a unique and modern appearance, and easily removed for cleaning.
As can be seen, there is a need for an improved air diffuser, as herein described. Embodiments of the present invention include air diffusers with a linear slot that are decorative and can be easily removed to clean the device and ductwork.
In one aspect of the present invention, an air diffuser comprises: a base configured to attach to a surface proximal an air duct and defining an air-in opening through which air is configured to flow in a first direction; and a diffuser plate detachably coupled to the base, the diffuser plate and base defining a laterally disposed air-out opening that is configured to direct the air in a second direction that is substantially perpendicular to the first direction.
In certain embodiments, the air-out opening is elongated.
In certain embodiments, the air-in opening and the air-out opening are oriented substantially perpendicularly relative to one another.
In certain embodiments, the air-in opening and the air-out opening are the only two openings extending out of the air diffuser.
In certain embodiments, a bottom surface of the diffuser plate is ornamented.
In certain embodiments, the diffuser plate comprises four lateral sides, with the diffuser plate clipably coupling to the base at first, second, and third lateral sides of the four lateral sides.
In certain embodiments, the air-out opening is disposed at a fourth lateral side of the fourth lateral sides.
In certain embodiments, the base comprises an air out deflector that partially defines the air-out opening.
In another aspect of the present invention, an air diffusing system comprises: an air duct operably coupled with a surface; and an air diffuser comprising: a base attached to the surface proximal the air duct and defining an air-in opening through which air is configured to flow in a first direction; and a diffuser plate detachably coupled to the base, the diffuser plate and base defining a laterally disposed air-out opening that is configured to direct the air in a second direction that is substantially perpendicular to the first direction.
In certain embodiments, the second direction is directed into a room space.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description, and claims.
The following figures are included to illustrate certain aspects of the present disclosure and should not be viewed as exclusive embodiments. The subject matter disclosed is capable of considerable modifications, alterations, combinations, and equivalents in form and function, without departing from the scope of this disclosure.
The subject disclosure is described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure such that one skilled in the art will be enabled to make and use the present invention. It may be evident, however, that the present disclosure may be practiced without some of these specific details. For the purpose of clarity, technical material that is known in the technical fields related to the present invention has not been described in detail so that the present invention is not unnecessarily obscured
Broadly, an embodiment of the present invention provides an air diffuser that includes (1) a base mount attachable to a surface proximal an air duct and (2) a diffuser plate attached to the base mount to form an assembly, the assembly defining an elongated slot, along a first side thereof, for diffusing air from the air duct into a building space.
As mentioned above, embodiments of the present invention solve many problems, including but not limited to: limited decorative/style options, the unfinished look behind grille, and difficulty removing/re-installing for cleaning. Embodiments of the present invention solve those problems by (1) providing a decorative new option, with a modern linear style, (2) minimizing and streamlining the air opening, and blocks the unfinished view of the ductwork, and (3) easily detaching for cleaning and reattaching with no dusty mess.
The present invention provides a unique modern option of a decorative air diffuser that is more stylish than the same old louvered face grille and mounts easily over the existing opening with no reconstruction work required above the ceiling. Embodiments are decorative new options for the residential air diffuser, with a modern linear slot style that easily installs over the existing ductwork opening and does not require any ceiling renovation work. The linear slot includes an integral throat section and advantageously eliminates any potential view of the ductwork and/or connection at the ceiling. To install, a user would simply remove the existing grille or diffuser and mount the new device over the opening. The diffuser plate can thereafter be easily removed for cleaning of the device and ductwork.
Referring now to
As shown from
To support a securely fastened assembly over long periods of time, one or more magnetic strips 22A, 22B may be adhered to or embedded in the angled face of each groove 20A and protrusion 22B to help hold them in engagement. These magnetic strips 22A, 22B, in general, constitute a magnetic coupling mechanism 22. While preferred embodiments of the present invention define the mounting base 12 and diffuser plate 14 as separate parts, it is within the scope of the present invention if they are made integral with one another to form a singular unit.
The decorative diffuser plate 14, as shown in
Additionally, the back pressure of the diffuser plate 14, aforementioned throat section, and air out deflector 24 also help to distribute the air across the full length of the diffuser, while the back angle member 28 helps to guide the airflow and reduce turbulence and the pressure drop through the diffuser 10.
The dimensions of the components of the air diffuser 10 could be varied based on the design airflow required. A length of the diffuser slot opening 18 could vary, for example, from 12 inches to 48 inches and the opening size of the slot could vary, for example from 1 inch to 2 inches.
In other embodiments, the diffuser 10 could be designed for single direction flow, or double direction (2 way) flow by providing a second opening on an opposite side of the diffuser 10. Further, instead of a ceiling 11a, the diffuser 10 could also be mounted on a wall or floor opening for similar use.
The mounting base 12 and diffuser plate 14 are both necessary for the function of the diffuser 10. However, as mentioned above, the overall dimensions of the parts can be varied to provide for larger or smaller airflow quantity. Anchors and screws could be optional if other means of installation are preferred, such as glue, silicone, etc. As described above, one or more magnetic strips or small discs could be used, in addition to or in place of the overlapping mechanical joint, to easily attach the diffuser plate 14 to the mounting base 12e, once fastened to the ceiling. This would also allow for easy removal to clean the device or the ductwork.
Further, an adjustable deflector lip could be added to provide a means to direct the airflow at a specific angle from the ceiling. Also, a guillotine type (telescoping) damper could be provided at the air-in opening 16 to allow for adjustable airflow balancing. Another option could be a light emitting diode (LED) strip to illuminate the diffuser slot (thus projecting light onto the ceiling at the air discharge for enhanced visual effect and decoration). The colors could be manually controlled, or automatically controlled based on the temperature of the supply air using a thermistor. For example, blue light could be emitted when cool air is supplied, or red/orange/yellow light be emitted when heating air is supplied. Finally, a similar configuration could be utilized as a return intake. However, for this application the overall dimensions would be significantly larger to account for proportionally more airflow of a typical central return air intake.
A method of making the present invention may include the following. The components may be formed from a die cast or extrusion process using a plastic or composite material that is lightweight, durable, and non-corrosive. Some milling and cutting of excess material may be necessary. In certain embodiments, the end pieces may be glued or mechanically fastened. Each part is intended to be made of a single uniform solid piece of material for better durability. Polishing and painting of the exterior may be required for custom color and appearance.
Alternately, the components may be formed from a stamping process using sheet metal steel or aluminum. Similarly, some machining and polishing may be required for appearance.
A method of using the present invention may include the following. To install the decorative diffuser, a user starts by removing the existing ceiling grille (if replacing an existing one). Next, the mounting base 12 is fastened to the ceiling using drywall anchors and/or screws/anchors through fastener openings 26. The baseplate should ideally be aligned in the desired direction of throw, but most likely in the same direction of the previous grille throw. Finally, the diffuser plate 14 is attached to the mounting base 12 using the overlapping mechanical joint on three sides of the assembly, and optionally the magnets 22A, 22B for additional support.
