- Scented candles release an aroma into the ambient atmosphere when burned, and are increasing in popularity. Such candles are often used for enhancing the ambience or mood in the home or workplace. Despite their popularity, there are some perceived problems associated with the burning of scented candles. The presence of an open flame can present hazards to children and pets, and burning candles present a fire hazard and should not be left unattended. Also, the smoke produced by burning candles can present a health or a nuisance hazard, and can complicate respiratory problems for particular individuals. Furthermore, smoke from the burning candle can damage or discolor furniture, walls and fabrics.

Description
- This application is a continuation application of U.S. Ser. No. 11/028,786 filed on Jan. 4, 2005, which claims priority of U.S. provisional patent application Ser. No. 60/535,867, filed Jan. 12, 2004, and entitled “Candle Warmer.”
- This invention relates generally to heating devices. More specifically, the invention relates to a heating device which is operable to receive and retain a scented candle and to maintain it at an elevated temperature relative to an ambient temperature so as to facilitate the dispersal of scent therefrom.
- Scented candles release an aroma into the ambient atmosphere when burned, and are increasing in popularity. Such candles are often used for enhancing the ambience or mood in the home or workplace. Despite their popularity, there are some perceived problems associated with the burning of scented candles. The presence of an open flame can present hazards to children and pets, and burning candles present a fire hazard and should not be left unattended. Also, the smoke produced by burning candles can present a health or a nuisance hazard, and can complicate respiratory problems for particular individuals. Furthermore, smoke from the burning candle can damage or discolor furniture, walls and fabrics. Thus, it will be seen that while the effects of scented candles are desirable, there are problems associated with the open flame attendant upon their use.
- Consequently, the prior art has sought to implement solutions whereby a candle's scent may be released without the requirement of utilizing an open flame. Toward that end, the prior art has investigated various designs of candle warming devices which allow scented candles to flamelessly disperse their aroma. The previous implementation of such a candle heater comprised the use of miniature hotplates, of the type employed for heating individual beverage cups; and in such instance, the candle, which is typically contained in a glass vessel, is placed onto the hotplate. In some instances, these hotplate-type candle warmers have a collar which surrounds a portion of the length of the candle; but they are not designed to enclose the entire length of the candle. This approach is less than satisfactory since only the bottom portion of the candle is heated. As a consequence, it takes a relatively long time to melt the upper surface of the candle wax so as to release the scent. This lag time can be shortened if the heat level of the hotplate is raised to a fairly high value; however, these high heat levels can pose a bum hazard once the candle is fully warm. Also, high heat levels can start to vaporize the candle wax thereby generating unwanted odors and damaging fumes. In addition, the heated wax fumes can present a significant fire hazard. Hotplate-type candle warmers are shown, for example, in U.S. Pat. No. 6,627,857. Another prior art approach to warming scented candles involves the use of a radiant heater which projects infrared light onto an upper surface of the candle. Devices of this type are relatively complicated and energy inefficient. Radiant candle heaters are shown in U.S. Pat. No. 6,354,710.
- As will be explained hereinbelow, the present invention is directed to a flameless candle heating device which efficiently and safely retains scented candles and the like and warms them to a uniform temperature optimized for safety and release of scent. These and other advantages of the invention will be apparent from the drawings, discussion and description which follow.
- There is disclosed herein a device for retaining and heating a scented candle or other body of scented hydrocarbon material. The device includes a housing which is fabricated from a body of a low thermal conductivity material. The housing has a substantially open top and comprises at least one sidewall and a base, which cooperate to define a partially enclosed interior volume which is configured to receive and retain the entire length of a candle therein. The device further includes an electrical heater which is in thermal conductivity with the housing. The heater is operable to warm the body of scented hydrocarbon material so that its scent exits through the open top of the housing.
- The housing may, in some instances, be a unitary body, while in other instances it may comprise an assembly of multiple pieces. The housing has a relatively low thermal conductivity, as defined herein, and may, in some instances, be fabricated from a body of ceramic material. In other instances, it may comprise a relatively high thermal conductivity material such as a metal combined with a body of insulating material.
- In specific embodiments, the device can include a temperature controller for regulating its operation, as well as other features, such as a pilot light, an on/off switch, and the like.

FIG. 2 is a cross-sectional view of the device ofFIG. 1 taken along section line A-A; -
FIG. 3 is a cross-sectional view of another embodiment of a heating device of the present invention; and -
FIG. 4 is a schematic depiction of one circuit which may be used to energize the electrical heater in warming devices of the present invention. - The present invention comprises a device for uniformly heating a scented candle so as to release its aroma, without the necessity of employing an open flame. The device of the present invention includes a housing which is fabricated from a body of low thermal conductivity material, as will be explained and defined hereinbelow. The low thermal conductivity housing encloses a scented candle. The device further includes an electrical heater which is in thermal communication with the housing. The housing operates to retain heat and allows the heater to uniformly heat the entire body of the candle without generating large temperature extremes. Since the housing shields the heated candle, it provides additional safety.
- Referring now to
FIG. 1 , there is shown a perspective view of oneembodiment 10 of a candle heater structured in accord with the principles of the present invention. As will be seen, thewarming device 10 includes abody 12 which includes abase portion 14 which is integral therewith. Thebody 12 has a generallycylindrical sidewall 15 which cooperates with the base portion thereof 14 to define and enclose an interior volume. In specific embodiments, this interior volume is sufficiently large so as to contain substantially all of the length of a candle disposed therein. The configuration of thebody 12 is such that its top is substantially open so as to permit the insertion of acandle 16 thereinto. The substantially open top also facilitates the dispersal of aroma from thecandle 16 in the operation of the device. It is to be understood that the top is shown as completely open in these figures; however, the top may be partially covered by a perforated plate, a mesh, or other such covering, provided that the covering has significant open space therethrough to permit dispersal of the aroma. As such, the presence of top members of this type does not preclude the top from being defined as “substantially open.” - The device of
FIG. 1 includes apower cord 20 for connecting its heater (not shown in this drawing) to a source of electrical power. As illustrated, the power cord includes an on/offswitch 22; although, this item is an option in the present invention. The warmer 10 ofFIG. 1 also includes anindicator light 24 which is lit when the heater is energized so as to provide a visual indication of the operation of the device. This is also an optional feature of the present invention. Another optional feature of the present invention is a temperature control device such as thedial control 26 shown inFIG. 1 . This control allows the user of the device to regulate the temperature of the heater. In other embodiments, this temperature controller may be eliminated. In yet other embodiments, temperature control may be automatic, by means of a thermostat, thermistor, or similar device. - Referring now to
FIG. 2 , there is shown a cross-sectional view of the warmingdevice 10 ofFIG. 1 taken along line A-A. As will be seen, thedevice 10 includes abody portion 12 which further includes a base 14 integral therewith. The body portion is fabricated, at least in part, from a material having a low thermal conductivity. In general, a low thermal conductivity is understood to be a thermal conductivity less than that of steel. Steel and other iron alloys typically have a thermal conductivity in the range of 0.16 (cal/sec)/(cm2° C./cm). Most typically, the low thermal conductivity materials of the present invention have a thermal conductivity which is less than 0.01 (cal/sec)/(cm2° C./cm), and in particular instances, have a thermal conductivity which is less than 0.005 (cal/sec)/(cm2° C./cm). Ceramics are one low thermal conductivity material which may be utilized in the present invention, and a typical thermal conductivity for such ceramic materials is in the approximate range of 0.005-0.001 (cal/sec)/(cm2° C./cm). Other low thermal conductivity materials include various polymers, which term also encompasses polymer-based composites, such as glass or mineral filled polymers, or polymer coated materials such as metals, provided that such structures fall within the definition of low thermal conductivity. - Shown in the
FIG. 2 embodiment is anelectrical heater 28 which is disposed at abottom portion 35 of aninterior volume 37 enclosed by thehousing 12. Although not shown in this view, it is understood that this heater is in electrical communication with a source of electrical power via a power cord or the like, as is better shown inFIG. 1 . - As can be seen from
FIG. 2 , ascented candle 16 is disposed within thebody 12 so as to be heated by theheater 28. As shown, thecandle 16 includes awick 30 and a body of scentedwax 32, which may at least be partially circumscribed by a body ofmaterial 33. Since the heater of the present invention eliminates the need for burning the candle, thewick 30 may be eliminated. It is also to be understood that the body ofwax 32 may be replaced by an oil or other such hydrocarbon material which will dissolve and retain a scent agent. Accordingly, it is to be understood that within the context of this disclosure, the term “scented candle” is to be interpreted very broadly so as to include all bodies of scented hydrocarbon material, both liquid and solid, whether they include a wick or not. - The present invention may be implemented in various embodiments, and
FIG. 3 illustrates one other embodiment of candle warmer 40 including ahousing 60 and a base 44 structured in accord with the present invention. TheFIG. 3 embodiment includes a two-part housing comprised of acylindrical sidewall member 42 that is U-shaped in cross-section and defined byopposed wall portions 52 that form an insulatingair space 50 within thecylindrical sidewall member 42. Thecylindrical sidewall member 42 is disposed upon atop portion 62 of the base 44 which has anelectrical heater 46 supported thereupon. As in the previous embodiment, thehousing 60 defines aninterior volume 48 which is substantially open at its top and which is configured to receive and retain a candle (not shown) therein. - The
FIG. 3 embodiment also differs from theFIGS. 1 and 2 embodiment insofar as the sidewall portion of thehousing 42 is fabricated from a relatively high thermal conductivity material such as sheet metal; but, it is further configured to define an insulatingair space 50 betweenopposed wall portions 52. Thisenclosed space 50 may be left empty, or may be filled with an insulating material such as a glass or a mineral fiber. The thermal conductivity of the material (air or insulating fiber) in the enclosedspace 50 is very low. Hence, the overall thermal conductivity of thesidewall member 42 is low, within the definitions established herein. Yet other variations of the present invention may be likewise implemented. - Referring now to
FIG. 4 , there is shown a schematic diagram of one circuit which may be employed for energizing the electrical heater used in the device of the present invention. Shown inFIG. 4 is anelectrical heater 28 which is electrically energized, in this case, by a source of alternating current 54. Anelectrical switch 22 allows for the selectable energization of theheater 28. Apilot light 24 is also electrically connected to thegenerator 54 via theswitch 22 so that the light will be lit whenever theheater 28 is energized. - Also shown in
FIG. 4 is atemperature controller 56 which is associated with theheater 28. Thetemperature controller 56 operates to regulate the flow of electrical energy to theheater 28, thereby controlling the temperature of the heater. In some instances, the temperature controller may comprise a thermostat having a preset temperature point, and will operate to maintain the heater at a preselected temperature. In one embodiment, the temperature of the heater is regulated so that the body of hydrocarbon material in the device of the present invention does not exceed 75° C. In other instances, the temperature controller may comprise a thermostat which can be user-set to a desired temperature. In yet other instances, the temperature controller may comprise a variable resistor which a user can set to control the temperature of the heater. In yet other instances, the temperature controller may comprise a temperature responsive electronic device such as a thermistor. - In one mode of operation of the present invention, the
temperature controller 56 may operate to initially energize the heater at a fairly high power level to provide for a rapid initial temperature rise in the heating device; and, the controller will further operate so that when a target temperature is reached, the power to the heater will be stepped-down to a lower level sufficient to maintain a desired temperature. Yet other modifications and variations of the power circuit will be readily apparent to those of skill in the art. - It is to be understood that the foregoing drawings, discussion and description are illustrative of specific embodiments of the present invention, but are not meant to be limitations upon the practice thereof. In view of the teaching presented herein, numerous modifications and variations of the invention will be apparent to those of skill in the art. It is the following claims, including all equivalents, which define the scope of the invention.
