Auxiliary heater device
An auxiliary heater device is for use with a primary room heater, the primary heater having a heating element cycling between operational and non-operational phases. The heater device includes 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 device 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 device is in a non-operational phase to reduce temperature fluctuations within the room. Preferably, the body is formed as an elongated tube disposeable upon an upper surface of the primary heater and the thermal retentive material is a semi-solid or gel disposed within the body tube.
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.
SUMMARY OF THE INVENTIONIn 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.
The foregoing summary, as well as the detailed description of the preferred embodiments of the present invention, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there is shown in the drawings, which are diagrammatic, embodiments that are presently preferred. It should be understood, however, that the present invention is not limited to the precise arrangements and instrumentalities shown. In the drawings:
Certain terminology is used in the following description for convenience only and is not limiting. The words “lower”, “upper”, “upward”, “down” and “downward” designate directions in the drawings to which reference is made. The words “inner”, “inwardly” and “outer”, “outwardly” refer to directions toward and away from, respectively, a designated centerline or a geometric center of an element being described, the particular meaning being readily apparent from the context of the description. Further, as used herein, the word “connected” is intended to include direct connections between two members without any other members interposed therebetween and indirect connections between members in which one or more other members are interposed therebetween. The terminology includes the words specifically mentioned above, derivatives thereof, and words of similar import.
Referring now to the drawings in detail, wherein like numbers are used to indicate like elements throughout, there is shown in
Preferably, the thermal 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 the heater device 10. The absorbed heat is then subsequently emitted or released from the thermal retentive 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 the heater device 10 and is more slowly emitted or released from the thermal retentive material 14 and into the room R. Thereby, the heater 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.

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 gel retentive material 14 is preferably configured to absorb an amount of heat sufficient to raise the temperature of the retentive material 14 to at least ninety degrees Celsius (90° C.), and with certain heater applications, an appropriate retentive 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 thermal retentive material 14 is unnecessary and beyond the scope of the present disclosure. However, it is worth noting that the preferred gel providing the thermal retentive material 14 in the heater 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 thermal retentive material 14 may be provided by any gel or gel-like material, specially manufactured or otherwise, capable of retaining heat such that the heater 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 thermal retentive 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.

For example, the flexible tube 18 may be formed of hollow tubular sections 26 integrally connected by solid divider portions 28, which may be formed by thermally fusing together (i.e., melting) several relatively short sections along the length of the flexible polymeric tube 18, as depicted in

Preferably, the body 12 is removably mountable to the primary heater 10, and is most preferably disposeable upon a generally horizontal support surface 3 of the primary heater 1, e.g., provided by the upper wall 4a of a heater housing 4. The heater 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, the heater device 10 may be readily mounted on the primary heater 1 merely by placing the body 12 on the heater support surface 3, and is also easily removable from the heater 1 by simply lifting the body 12 from the support surface 3.
More specifically, when used with a relatively wide primary heater 1, as shown in
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 primary heater 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, the heater 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, the heater device 10 may even be disposed or mounted within the heater housing 4, either removably or fixedly.
