Description
- This application claims the benefit of U.S. Provisional Application No. 61/227,019, filed Jul. 20, 2009, the entire contents of which are incorporated by reference herein.
- The present invention relates to heater devices, and more particularly to heater devices for maintaining the temperature of a room or other enclosed space.
- A typical room heater device operates in a cyclical manner in which thermal energy is delivered in an operational phase to increase or maintain room temperature, and then alternatively heat emission or delivery is ceased in a non-operational phase to avoid excessive temperatures. For example, the room heater device may include an electric heater with a plurality of resistive heating elements, a “hot water” heater device including pipes through which heated water is directed, or a furnace with a plurality of ducts for emitting forced air into the room. Typically, these room heater devices operate until a predetermined maximum room temperature is reached, or for a predetermined period of time, and then switch to a non-operational phase until the temperature falls below a predetermined minimum temperature or until after a predetermined period of time.
- In one aspect, the present invention is an auxiliary heater device for use with a primary room heater, the primary heater having a heating element cycling between operational and non-operational phases. The heater device comprises a body configured to be disposed at least generally proximal to the primary heater, the body being either formed of a thermal retentive material or containing a quantity of thermal retentive material. As such, heat generated by the primary heater is absorbed by the retentive material and subsequently emitted by the retentive material into a room so that the auxiliary heater device emits heat when the primary heater is in a non-operational phase to reduce temperature fluctuations within the room.
- In another aspect, the present invention is again an auxiliary heater device for use with a primary room heater, the primary heater cycling between operational and non-operational phases. The heater device comprises a container having an interior chamber and being sized to be disposable at least generally proximal to the primary heater and a quantity of thermal retentive material disposed within the container chamber. The thermal retentive material is configured to absorb and emit thermal energy, such that heat generated by the primary heater is absorbed by the retentive material and subsequently emitted from the container. As such, the auxiliary heater emits heat when the primary heater is in a non-operational phase to reduce temperature fluctuations within a room.

retentive material 14 is configured to emit a particular quantity of heat at a rate substantially lesser than a rate of emission of the quantity heat by the primary heater 1. For example, the primary heater 1 may emit one British thermal unit (BTU) of heat every second (1 BTU/s), at least a portion of which is absorbed by theheater device 10. The absorbed heat is then subsequently emitted or released from the thermalretentive material 14 at a rate of, for example, one-half British thermal unit of heat unit per second (½ BTU/s). As such, heat that is relatively quickly emitted by the primary heater 1 accumulates within theheater device 10 and is more slowly emitted or released from the thermalretentive material 14 and into the room R. Thereby, theheater device 10 continues to release a substantial amount of heat into the room R while the primary heater 1 is in a non-operational phase. - Referring to
FIGS. 9 and 11 , thebody 12 is preferably generally elongated such that theheater device 10 is configured to absorb and emit heat along a substantial length LH of the primary heater 1. More specifically, most conventional room heaters 1, such as baseboard heaters, have a substantial length LH (SeeFIGS. 9 and 11 ) in order to better distribute heat within a room R. As such, thebody 12 of theheater device 10 also preferably has a substantial length LB so as to more efficiently absorb heat from the primary heater 1 and subsequently distribute the heat across/within the room R. - Referring now to
FIGS. 3-8 , with the preferred structure of a separate quantity or mass of thermalretentive material 14 disposed within the body 12 (i.e., as opposed to abody 12 formed of the material 14), thebody 12 preferably includes acontainer 16 with an interior chamber CB, with the thermalretentive material 14 being disposed within the body chamber CB. Preferably, the thermalretentive material 14 remains substantially static within the body chamber CB during use of theheater device 10. In other words, the thermalretentive material 14 is intended to absorb and release heat as a generally static material mass primarily by conduction, with no or minimal movement of theretentive material 14, as opposed to a forced convective heat transfer, such as for example, fluid flow occurring in a conventional heat exchanger. - Further, the thermal
retentive material 14 is preferably a highly viscous liquid or a semi-solid, i.e., a gel or “gel-like” material, at room temperature (i.e., between about 20° C. and 25° C.) and preferably remains a gel or semi-solid within at least an operating range of temperatures between about twenty degrees Celsius (20° C.) and about eighty degrees Celsius (80° C.), most preferably above and below this temperature range. The semi-solid or gelretentive material 14 is preferably configured to absorb an amount of heat sufficient to raise the temperature of theretentive material 14 to at least ninety degrees Celsius (90° C.), and with certain heater applications, an appropriateretentive material 14 may be selected that is capable of achieving temperatures much greater than 90° C. - Furthermore, the thermal
retentive material 14 may be provided by any appropriate commercially available gel as used in such devices as “hot packs” or “cold “packs” for applications such as injury treatment, warming, cooling, etc. As such materials are generally known, a detailed description of the chemical composition of the thermalretentive material 14 is unnecessary and beyond the scope of the present disclosure. However, it is worth noting that the preferred gel providing the thermalretentive material 14 in theheater device 10 may include a mixture of water and a polymer, a glycol (e.g., propylene glycol or ethylene glycol), silica and/or sodium, and may further include additional binding, filling or property-enhancing substances, such as clay, cellulose or fibrous materials. Further, the thermalretentive material 14 may be provided by any gel or gel-like material, specially manufactured or otherwise, capable of retaining heat such that theheater device 10 functions as generally described herein, whether such substance is presently known or invented/discovered after the present disclosure. Although preferably in the form of a gel or gel-like material, the thermalretentive material 14 may alternatively be a powder or a more conventional liquid, or even a solid if a one-piece heater device 10 is “one-piece”, within any portion of the desired operating temperature range. - Still referring to
FIGS. 3-8 , thebody 12 preferably includes anelongated tube 18 having awall 20 with inner and outer surfaces 20 a, 20 b and a thickness tW, the inner surface 20 a defining a generallycylindrical bore 21 that provides the body interior chamber CB, as best shown inFIG. 8 . The thermalretentive material 14 is distributed within the chamber CB so as to form a substantiallyuniform mass 15 having a thickness tM (FIG. 7 ) substantially greater than the wall thickness tW (i.e., tM>tW). Further, thebody tube 18 is preferably formed of a material having a thermal conductivity that is sufficiently lesser than the thermal conductivity of theretentive material 14 so as to reduce a rate of heat emission from themass 15 of thermalretentive material 14. By having a lesser conductivity than the thermalretentive material 14, thebody tube 18 will provide thermal resistance that tends to retain heat within themass 15 of thermalretentive material 14, thereby acting to reduce the rate of heat release or emission from theheater device 10 to increase the overall duration of heat emission from thedevice 10. However, by having a relatively small or lesser wall thickness tW, the thermal resistance of thebody tube 18 does not prevent a sufficiently high rate of heat transfer from the primary heater 1 to theheater device 10 during the operational phase of the primary heater 1. Preferably, theheater body tube 18 is formed of a substantially rigid material, most preferably a polymeric or plastic material such as, for example, high-density polyethylene (“HDPE”), polyvinyl chloride (“PVC”), Delran, Nylon, etc., but may be formed of any other material that enables theheater device 10 to generally function as described herein. - Referring to
FIGS. 3-5 , with a generallyrigid body 12, thebody tube 18 preferably further includes a pair ofend walls 22A, 22B attached to, or integrally formed with, aseparate end 18 a or 18 b of thebody tube 18. Preferably, a fill port 23 extends through at least one of theend walls 22A or 22B, but may alternatively extend through thetube wall 20. The one or more fill ports 23 is/are used to fill the body chamber CB with the thermalretentive material 14, and may also be used to evacuate the material 14 from the chamber CB. Further, aplug 24 seals each fillport 20 and may be either removably mounted (e.g., threadably) or permanently mounted (e.g., cemented) to theend wall 22A or 22B. - As best shown in
FIG. 8 , therigid body 12 is preferably formed as a cylindrical solid with generally rectangular or generally trapezoidal cross-sections. Most preferably, thebody tube 18 is formed having generally flat, generally parallel top andbottom surfaces 25, 26, a curved front surface 27, and a generally flatrear surface 28 that extends substantially at right angles with respect to thebottom surface 26. With this preferred body structure, theheater device 10 is provided with alternative first and second mounting orbase surfaces bottom surface 26 andrear surface 28. Eachbase surface surface first base surface 29A may be used to mount the heater device to a relatively wider primary heater 1 and thesecond base surface 29B may be used to mount the heater device to a relatively narrow primary heater 1, as described in greater detail below. - Referring to
FIGS. 13-16 , theheater tube 18 may be alternatively formed of a substantially flexible material, such as for example, a thermoplastic polyvinyl, PVC film, etc. With such a flexible tube structure, the end walls are not required as the each tube end 18 a, 18 b may sealed together by bonding (e.g., with glue or cement) or thermal fusion (i.e., melted) so as to enclose the body interior chamber CB. Also, with aflexible tube 18, thebody 12 may be formed having a plurality of chambers or sub-chambers cN with the thermalretentive material 14 being distributed among the chambers c1, c2, c3, . . . cN (SeeFIG. 16 ). The plural-chamber body tube 18 is configured to be separable between each pair of adjacent chambers cN while retaining theretentive material 14 disposed within the chambers cN, such that theheater device 10 is or adjustably or selectively sizeable to the primary heater 1. - For example, the
flexible tube 18 may be formed of hollowtubular sections 26 integrally connected bysolid divider portions 28, which may be formed by thermally fusing together (i.e., melting) several relatively short sections along the length of theflexible polymeric tube 18, as depicted inFIG. 16 . With such as multi-section ormulti-chamber heater device 10, theheater device 10 may be commercially provided in a standard length, with the intention that an installer will determine the actual length of thebody 12 necessary to “cover” a substantial portion of the length of an existing primary heater 1, as discussed below. The installer will then cut through adivider section 28 to obtain the desired length, such that the multi-chamber construction of theheater body 12 thus facilitates installation into existing room heating systems. - Referring to
FIGS. 1 , 2 and 9-12, by being locatable with respect to the primary heater 1 such that the thermalretentive material 14 is spaced from the primaryheater heating element 2, as opposed to surrounding theelement 2 or being in direct contact therewith, thebody 12 of theheater device 10 is separate or separable from the primary heater 1. Also, theheater body 12 is preferably sized so as to be supported by the primary heater 1. As such, thepreferred heater device 10 is readily adaptable or “retrofittable” to any conventional primary heater 1, such as for example, a baseboard heater (as depicted) or a radiator (not shown), already installed within a room R. - Preferably, the
body 12 is removably mountable to theprimary heater 10, and is most preferably disposeable upon a generallyhorizontal support surface 3 of the primary heater 1, e.g., provided by theupper wall 4 a of aheater housing 4. Theheater body 12 is preferably merely supported by the primary heater 1 without connection or attachment, and is thus supported by the heater 1 generally in the manner of a shelf. As such, theheater device 10 may be readily mounted on the primary heater 1 merely by placing thebody 12 on theheater support surface 3, and is also easily removable from the heater 1 by simply lifting thebody 12 from thesupport surface 3. - More specifically, when used with a relatively wide primary heater 1, as shown in
FIGS. 9 , 10, 15 and 16, theheater body 12 is oriented such that thefirst base surface 29A is placed upon the primaryheater support surface 3, with thesecond base surface 29B being vertically oriented and preferably disposed against (or at least proximal to) an adjacent section of a vertical wall surface SW. Alternatively, when used with a relatively narrow primary heater 1, as depicted inFIGS. 1 , 2, 11 and 12, theheater body 12 is oriented such that thesecond base surface 29B is placed upon the primaryheater support surface 3 and thefirst base surface 29A is disposed against or proximal to the vertical wall surface SW. Thus, the preferred structure of thetubular body 18, as described in detail above, enables theheater device 10 to be adaptable for use with a wide variety of different sized primary heaters 1. - Although preferably supportably mounted on, but not connected with, the primary heater 1 as described above, the
heater device 10 may alternatively be removably attached to or connected with the primaryheater support surface 3 by any appropriate means, such as for example, by one or more removable adhesive strips (e.g., tape), by hook and loop fasteners, clips, brackets, threaded fasteners, etc. As a further alternative, theheater device 10 may be semi-permanently or permanently mounted or attached to the primary heater 1, for example by means of glue, cement, a similar bonding agent, or any other appropriate means. As yet another alternative, theheater device 10 may even be disposed or mounted within theheater housing 4, either removably or fixedly. - As shown in
FIGS. 3 and 5 , theheater body 12 preferably has at least one recess orcavity 30 formed in the tube outer surface 20 b and theheater device 10 preferably further comprises either athermometer 32 disposed within thecavity 30 or a quantity of a fragrance-emitting material disposed within thecavity 30. With athermometer 32, theheater device 10 is able to provide an indication of the temperature of the thermalretentive material 14. Further, with fragrance-emitting material, a portion of the heat emitted by the thermalretentive material 14 heats the fragrance-emitting material so that a scent is released or emitted into the room R. - Referring now to
FIGS. 17 and 18 , in use, theauxiliary heater device 10 of the present invention basically operates as follows. After installation onto (or within) the primary heater 1 as described above, a user may then operate the primary heater 1 such that heat is emitted (as indicated by arrows), i.e., conducted, convected and/or radiated, from the primary heater 1, a portion of which is absorbed by the thermalretentive material 14 of theheater device 10. Typically, as discussed above, a conventional room heater 1 cycles between an operational phase (FIG. 17 ), during which heat is emitted by one or more heating elements 2 (e.g., resistors, heat exchanger tubes, etc.) and a non-operational phase (FIG. 18 ) in which the emitted heat is substantially diminished, such as by means of cutting off the flow of electricity through aresistor heating element 2. Such phases may be determined by feedback control from a thermostat (not shown) or may be set to a predetermined duration for each phase (i.e., open loop control). During the non-operational phase, theheater device 10 continues to emit heat from the thermalretentive material 14, such that fluctuations of the temperature within a room R are substantially reduced or eliminated. Further, with primary heaters 1 controlled by close-looped controllers (none indicated), the maintenance of the room temperature by theauxiliary heater device 10 may reduce the duration of the operational phase, or increase the duration of the non-operational phase, which will decrease the power consumption of the primary heater 1 and provide cost savings. - It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present invention as generally defined in the appended claims.
