DETAILED DESCRIPTION
[0055] Reference will now be made in detail to embodiments of the present teachings, examples of which are illustrated in the accompanying drawings. It is to be understood that other embodiments may be utilized and structural and functional changes may be made without departing from the scope of the present teachings. Moreover, features of the embodiments may be combined, switched, or altered without departing from the scope of the present teachings, e.g., features of each disclosed embodiment may be combined, switched, or replaced with features of the other disclosed embodiments. As such, the following description is presented by way of illustration and does not limit the various alternatives and modifications that may be made to the illustrated embodiments and still be within the spirit and scope of the present teachings.
[0056] As used herein, the words “example” and “exemplary” mean an instance, or illustration. The words “example” or “exemplary” do not indicate a key or preferred aspect or embodiment. The word “or” is intended to be inclusive rather an exclusive, unless context suggests otherwise. As an example, the phrase “A employs B or C,” includes any inclusive permutation (e.g., A employs B; A employs C; or A employs both B and C). As another matter, the articles “a” and “an” are generally intended to mean “one or more” unless context suggests otherwise.
[0057]
[0058] As used herein, the simulated fuel source 120 may include artificial logs or log set 122, coal, an ember bed 124, an artificial grate 126, a background or screen 128 (e.g., simulated brick fireplace background), or other appropriate components, including novelty fuel sources (e.g., holiday themed fuel sources, user customized fuel sources, etc.). It is noted that some or all components of a simulated fuel source may be monolithically formed or formed of separate constructions that may be assembled together, unless context suggests otherwise or warrants a particular distinction among the terms. In an example, one or more of an artificial log set, ember bed, grate, or background may be monolithically formed, such as during a molding process. Molding processes may include blow molding, injection molding, vacuum molding, or the like. It is noted that ember bed 124, log set 122, or other components may comprise semi-translucent or translucent material so as to diffuse, reflect, or otherwise allow visible light to be displayed to a user.
[0059] In some embodiments, simulated fuel source 120 may be additionally or alternatively simulated via lighting displays 104 (e.g., monitors, televisions, screens, or the like), as described here and elsewhere in this disclosure. It is further noted that the simulated fuel source may include or be coupled with a light source that may provide visual flame effects. For example, some embodiments may utilize a light source (such as one or more light emitting diodes (LEDs), an array of lights, etc.) with or without a reflector, such as a rotatable reflector (e.g., flicker rod). The light source and reflector may be disposed in various appropriate positions, such as positioned completely or partially behind, beneath, above, or beside a fuel source. It is further noted that embodiments may utilize a flame screen (e.g., screen 128, mirrors, glass, or other surfaces) that may receive or otherwise reflect light. Such flame screens may provide additional or alternative flame effects.
[0060] In examples, the light source may comprise one or more of a LED down lighting system, an LED flame light system, an LED ember bed lighting system, an LED simulated fuel source lighting system, other functional electrical fireplace components, and a chassis incorporating such parts. According to at least one example, a light source or simulated fuel source 120 may include one or more rotating spindles which may include finger-like projections comprising reflective material. The rotating spindles may be rotated by one or more motors that may be coupled to a power source, such as a batter or power mains. It is noted that various components of the simulated fuel assembly 120 may be disposed at different locations, such as in front, above, behind, to a side, or the like (relative a front view of a simulated fuel source, wherein the front view is the view at which a user may have a line of site to the simulated fuel source.) Moreover, electrical components may be connected to one or more control circuits, such as a circuit disposed on a printed circuit board. Such control circuits may include a processor including or coupled to a memory that stores computer executable instructions. The processor may execute the instructions to perform functions, such as executing a burn program, controlling a motor, controlling one or more lights or the like. It is noted that the processor may communicate with the electrical components via wireless or wired connections.
[0061] In some embodiments, the fireplace system 100 may include or be inserted within a structure 102 that comprises multiple viewable sides, such as a dual, triple, quadruple, etc. sided firebox, or the like. As such, embodiments may include one or more simulated fuel sources 120 that may simulate burning fuel viewable by a user at any of the sides.
[0062] Aspects of a simulated fuel source 120 may include attachment mechanisms, such as mechanical fasteners, chemical fasteners, slots, clips, or the like for connecting components to a structure or to each other.
[0063] A heater assembly 150 or heater assembly 150s may include different types of heating elements such as radiant heat sources (e.g., heat lamps, etc.), forced air heat sources, fan forced convection, infrared, infrared with fan mode. As utilized herein, a heater assembly 150 may refer to one or more heater assembly 150s that may be separately constructed. For instance, embodiments may utilize multiple heater assembly 150s disposed in different housings. The heater assembly 150s may comprise the same, similar or different heating elements (e.g., radiant, forced air, etc.). In still other examples, a heater assembly 150 may refer to a fan without heating elements. Moreover, heater assembly 150 may include an inlet that receives ambient air and an outlet 152 to force air out of the heater assembly 150, such as heated air in a desired direction. It is noted that the inlet and outlet 152 may be fluidly connected such as through ducts that may define an airflow path. The airflow path may be directed to one or more baffles that may direct forced air, absorb radiant heat, or the like. In another aspect, as the air flowing through the airflow path passes through or near heating elements or heated components (e.g., heated baffles, heated ducts, etc.) the air may be warmed such that air forced from the exhaust may provide heat.
[0064] In at least some embodiments, fireplace systems may include audio devices 170 that may receive or generate sound waves. For example, fie place systems may include speakers that may generate appropriate sounds. Such sounds may include fire crackling, logs shifting, ambient noise (e.g., animal sounds, wind, water ways, etc.), music, audiobooks, podcasts, radio programs, or the like. As another example, speakers may include or be communicatively coupled with devices that may connect to communication networks (e.g., wireless receivers, user devices, etc.). The speakers may enable playback of streaming or downloaded content stored in a local memory, in memory on a user’s device, or the like. For instance, a user may stream or otherwise playback audio via the speakers of the fireplace system. It is noted that the fireplace system may include speakers disposed within the simulated fuel source 120, within a heater assembly 150, in a set-top control unit, wirelessly connected speakers (e.g., BLUETOOTH speakers, speakers on a user’s device, etc.), or other speakers.
[0065] It is further noted that described fireplace systems may include an interface device 160, such as user input or output (I/O) devices, tactile buttons, touch screen or resistive buttons, microphones, pressure sensors, light sensors, cameras, keyboard, mouse (e.g., pointing device), joystick, remote controller, gaming controller, a stylus, a remote controller (e.g., wired or wireless, including user devices), or the like. Such interface devices may be localized to one component of the fireplace system (e.g., the heater assembly 150, the simulated fuel source, a portion of furniture, a separate control panel or box) and/or may be distributed across multiple components. The interface devices 160 may allow a user to control or modify parameters of a burn program, create custom programs, or manually adjust parameters.
[0066] It is noted that the interface device(s) 160 may be communicatively coupled to a control circuit. The control circuit may include or be coupled to a processor 162. The processor 162 may include or be coupled with a memory device. The memory device may be configured for storing computer executable components. Processor 162 may facilitate operation of the computer executable instructions. It is noted that system 100 may include one or more devices that may include a processor 162, such as a user device, the simulated fuel assembly 120, the heater assembly 150, set-top boxes, control panels, or the like. It is further noted that one or more devices may comprise a processor that, at least in part, controls or executes instructions for controlling the various components. For instance, a single component of system 100 may include one or more central control processors 162 that sends or distributes instructions to processors 162 contained in the other components. Accordingly, while examples may refer to a particular processor 162 executing or controlling a component, it is noted that other processors 162 disposed in other devices may control any particular component.
[0067] In an example, a user may utilize the interface device 160 on the heater assembly 150 or a user device to manually control certain parameters of the system 100. Such parameters may include turning components on/off, modifying lighting (e.g., color, speed, intensity, pattern, etc.), setting or modifying a temperature, selecting or modifying sound parameters (e.g., volume, sound source, etc.). In an example, a user may interact with the interface device 160 to select a crackling sound that may be stored on a memory storage device or streamed from a user device, server, or the like. The processor 162 may generate instructions to an audio device 170 to select or playback the appropriate sound. It is noted that the user may select a particular light pattern or the processor 162 may automatically select a light pattern to match the selected sound. In other embodiments the user may select other parameters and the processor 162 may automatically select parameters to match the user selection (e.g., light intensity, color, heat, sound, etc.). Moreover, processor 162 may control the various components such as control parameters of individual LEDs, blower speeds, or the like.
[0068] Referring now to
[0069] It is noted that like named components of various systems described herein may comprise similar or identical aspects and/or functionality unless context suggests otherwise or warrants a particular distinction among such components. For example, fireplace system 200 may comprise the same, similar, or different components as system 100, such as a simulated fuel source, heater assembly, structure, audio device, and interface devices.
[0070] Conventional wisdom teaches that such fireplace inserts should be constructed so that all components are retained in a single housing or insert housing. Thus, all electronic and mechanical components are retained in one housing. Disclosed embodiments break from this conventional wisdom in this and other aspects that will be apparent herein. As an example, fireplace system 200 may comprise a modular fireplace insert 210 that may provide for flexibility in modifying a fireplace insert, flexibility in creating embodiments with a wide variety of features, ease of manufacturing, economic advantages, increased ability to modify components for assembly within various structures having different dimensional requirements. For instance, embodiments may include the simulated fuel source 220 comprising a first housing (which may house some or all components of the simulated fuel source 220) and the heater assembly 250 comprising a second housing. This may allow the heater assembly 250, as well as other components, to comprise high voltage parts that require an increased level of safety testing and certification, relative lower voltage parts, such as the simulated fuel source or other lighting, to be tested separate from lighting. The relatively low voltage lighting may be generally benign such that it requires less safety testing or different, if any, certification. Splitting these assemblies may allow a single heater assembly 250 to be utilized with various different simulated fuel sources, without having to re-engineer the heater assembly 250. It is noted that such embodiments may thus include a defined connection and control protocols which provide a series of rules or instructions such that control operations may interface with various components as described herein and elsewhere in this disclosure.
[0071] As shown in
[0072] Turning to
[0073] While the heater assembly 250 may be mounted in any desired location, the heater assembly 250 is generally positioned such that an inlet 352 may receive ambient air while an outlet 354 generally expels or forces air towards a front of the inlet housing 212 and fireplace system 200, where the front of the fireplace system 200 refers to the side viewable in
[0074] It is noted that some embodiments may include a plurality of heater assemblies 250 that may comprise the same, similar, or different heating element types. This may allow a single fireplace system 200 to be installed in large areas, such as in large rooms, multi-sided fireboxes, in commercial environments, or the like. Such heater assemblies 250 may be controlled by a single control unit (e.g., such as at an administrative control box), at their individual locations, or the like.
[0075] Turning now to
[0076] The housing 552 may contain operative elements, such as heating elements, a blow motor, baffles, and the like. The housing 552 may be generally compact or reduced in size such that it may be positionable in different structures or otherwise disposed in various locations. It is further noted that the housing 552 may be attachable to various different face plates 502. For instance, the housing 552 may be attachable to different face plates 502 of different dimensions (e.g., width, height, depth, etc.), ornamental design, or the like. In an example, the face plates 502 may be interchangeable using mechanical or chemical fasteners. The face plates 502 are structurally distinct from the housing 552, so that a single and standardized housing 552 can be paired with a face plate 502 of any appropriate size. The arrangement and attachment of the face plate 502 relative to the housing 552 and the broader system will be described in greater detail below.
[0077] As such, the heater assembly 550 may be utilized in a variety of different structures without having to redesign the heater assembly 550, obtain new certifications, or the like. In an example, the heater assembly 550 may be utilized in insert housings 212 for a fireplace system of different sizes, such as q inch fire place, where q is a number (e.g., 18”, 23”, 26”, 33”, 42”, etc.).
[0078] In still another method of the invention, the appearance of the heater assembly 250/550 may be altered by connecting, interchanging, and removing one or more face plates 502 with the heater assembly 250/550. The face plates can be decorative in nature and can be easily connected to and removed from the front portion of the fireplace housing using conventional fastening means, e.g., via attachment points.
[0079] In examples, the heater assembly 250/550 may include electronic controls, such as a control circuit that converts AC power into DC power to power various components. For instance, the heater assembly 250/550 may include a connection to power mains (e.g., electrical outlet, etc.). The heater assembly 250/550 may include circuitry to apply power to a simulated fuel source. It is further noted that the circuitry may generate and supply control signals to the simulated fuel source to control parameters, such as a color of light, intensity, speed, etc. For instance, as shown in
[0080] As described here and elsewhere in this specification, it is noted that the control circuitry may be disposed completely or partially in other devices, such as within the simulated fuel source 220, in a separate control unit, in a user device, or the like. It is noted, however, that supplying the control circuitry within the heater assembly 250 may allow for increased ability to utilize various different components with a heater assembly 250 without modifying the heater assembly 250 or requiring certification.
[0081] It is further noted that the described embodiments may allow for different combinations of heater assemblies and simulated fuel sources. For instance, different types of heater assemblies incorporating different heating technologies may be utilized with different types of simulated fuel sources, including different simulated fireplaces, simulated torches, simulated gas lamps, etc. The modularity disclosed herein provides great flexibility to swap out different heating technologies when a consumer purchases a unit or at any other time. In some examples, a system 100 may be packed and sold with multiple different types of simulated fuel sources 220 such that a user may attach or replace different simulated fuel sources 220 as they desire.
[0082] It is further noted that embodiments may allow for retrofitting by providing components that are both backwards and forwards compatible. In an example, a user may purchase a system 200. After some time, a user may desire to obtain a new model simulated fuel source 220 or heater assembly 250 while retaining their current insert housing 212 or structure 202. The user may be able to purchase a desired component and easily replace prior components with the new component. It is noted that embodiments may include a particular communication protocol that may allow a control circuit to identify a make and model of a new component, receive updated programming from a new component or other source (e.g., a user device, direct communications connection), or the like.

[0084]
[0085] According to at least one embodiment, the back panel 270 may comprise a back panel of the fireplace insert 210 or a flame screen that light projects onto. The back panel 270 may be attached to or a part of the insert housing 212 which may be assembled with the structure 202 such that a separate flame screen is not required. For instance, the back panel 270 and flame screen may be wood, plastic, wood based fiber board product, and laminated with veneer or furniture style laminate finishes (e.g., stone, brick, etc.). In some embodiments, other supports or side panels may additionally or alternatively include a decorative finish like brick or stone, solid colors, or designed to match a piece of furniture.
[0086] Moreover, such structures 202, 900, and 1000 may comprise routing to allow for cables to pass generally unseen by a user. Such routing may include apertures positioned in locations which are not visible when a system is fully assembled.

[0089] It is noted that embodiments may include other or different simulated fuel sources, including other or different light sources and the like such as described with reference to
[0090] According to various embodiments, a heater assembly or simulated fuel source may include or communicate with one or more sensors. The sensors may monitor heating, positioning of doors, objects blocking heating, or the like. The sensors may include proximity sensors, motion sensors, light sensors, tactile or mechanical sensors, reed switches, RFID devices (such as NFC devices), or the like. Such sensors may be integrated within the heater assembly, simulated fuel source, a structure, or may be removably attachable thereto. In an example, the heater assembly may include a sensor that monitors or detects when an object is or may be blocking an outlet of the heater. In such instance, the heater assembly may shut off heating so as to prevent overheating. In some examples, the heater assembly may detect an object utilizing an IR sensor. In other examples, portions of a structure may include actuators, such as a mechanical actuator, magnet for activating a reed switch, inductive coil, or the like. In other examples, a heater assembly may be positioned such that its outlet will not be covered by a closed door or drawer. This may allow a heater assembly to maintain operation while a simulated fuel source is blocked or hidden from view.
[0091] In at least one embodiment, multiple or different simulated fuel sources may be located or positioned in different portions of a structure. For instance, embodiments may include simulated gas lighting, candles, or other simulated fuel that may be positioned in or on a structure, as such embodiments may not include simulated fire places. Such multiple or different simulated fuel sources may be communicatively coupled to a heater assembly or control component.
[0092] Moreover, simulated fuel sources may be positioned at different locations on a structure, may be movable, retractable, or otherwise repositionable according to a user’s preference.
[0093] While the embodiments described above feature a reflector-containing rotating spindle to reflect light from flame light LEDs onto a projection screen, in other embodiments within the invention, the appearance of a flame can also be simulated using a spindleless device. For example, to create the appearance of flames, a ribbon fire system might be used wherein ribbons are placed between the flame light source and the projection screen and air is blown onto the ribbons to make them move in a side-to-side manner such that the light transmitted through the ribbons mimic the look of real flames on the projection screen. As another example, flames can be simulated in an electric fireplace lacking a rotating spindle using CPU-controlled flame light LEDs positioned behind a flame cutout panel which is behind a projection screen. In one such embodiment, the flame light LEDs are arranged in strips or a panel positioned roughly parallel to the flame cutout panel. Rather than using the mechanical movement of a reflective spindle to create a flame motion effect, this effect is generated directly using a program that causes the CPU to activate the flame light LEDs in a sequence that creates the appearance of a moving flame on the projection screen. Use of a multiple flame light LED system allows this to work because, unlike conventional incandescent lighting, each of the individual LEDs can be controlled with the exacting precision in a pre-determined sequence that results in an image of a realistic moving flame on the projection screen.
[0094] It is noted that the various components of structures 202, 900, and 1000 may be purchased and shipped in a deconstructed state. With reference to

[0096] Optionally, the simulated fuel source 220 can be placed within the insert housing before or after the heat assembly 250. Step 1508 is performed by fastening the housing of the simulated fuel source to the base 266 of the insert housing 212. A wire 532 from the simulated fuel source may be routed to communicate with the heat assembly 250. Wire clips (See

[0099] First, fireplace insert 210 may be constructed from standardized parts so as to allow for combinations that vary the dimensions of the final, assembled system 200 and/or structure 900, 1000. For example, the insert housing 212 may have a width of 23, 28, or 33 inches (and it will be understood the system 200 may be specifically reconfigured in the future to accommodate new iterations). However, the sequence in which the components 212, 220, 250 are assembled—both individual and in comparison to one another—significantly influences the ease with which the final system 200 can be assembled itself.
[0100] For example, heater assembly 250 or 550 comprises three discrete components: the main body 552 (which encloses the heating element, blower, controls, electrical items, and other functional components), the attachment brackets 410, and the face plate 502. As noted elsewhere herein, the face plate 502 is essentially an aesthetic element, and any number of different face plates 502 could be associated/used with a single, standardized heater body 552. Thus, during assembly, the face plate 502 is separately affixed to the insert housing 212 (or any of the numerous other structural housings for the cabinet). Separately, the brackets 410 are attached to the main body 552, and the bottom/lower-facing slots on the flanges of the bracket 410 are slid into place to insure proper positioning of the body 552 relative to the already-installed face plate 502. Lastly, the top edges of the flange are then secured to the housing 212 to complete the installation.
[0101] In the same manner, the simulated fuel source 220, 1100 is assembled as shown in
[0102] What has been described above includes examples of the present specification. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the present specification, but one of ordinary skill in the art may recognize that many further combinations and permutations of the present specification are possible. Each of the components described above may be combined or added together in any permutation to define embodiments disclosed herein. Accordingly, the present specification is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
