Definitions

  • This invention relates to controlling a burning flame, e.g., controlling the burning of a candle.
  • Safety is a typical concern when candles are burned in a house or otherwise where people or flammable objects are present.
  • the open flame of a candle is capable of catching curtains, clothing or other objects on fire, or burning a person through even inadvertent contact.
  • Another consideration when burning candles is the tendency of high wind or other air movement to blow the flame out.
  • various devices such as lanterns, shades, etc., have been developed to help prevent a candle flame from being extinguished by wind.
  • a "candle” refers to any device or substance that may have an open flame or otherwise be burned, including stick candles, votive candles, jar candles, incense, oil lamps or any other device having a wick or similar element to burn a fuel, etc.
  • a candle may be burned in an enclosed area so that people and objects around the candle's flame are prevented from contacting the flame. Air flow into the enclosed area may be controlled so that the flame is extinguished when air is no longer provided into the enclosed area. For example, a fan may move air into the enclosed area, providing air for combustion.
  • the flame may not receive enough air for combustion and be extinguished, e.g., within 1-5 minutes or less.
  • the environment in which a candle may be burned may be enclosed so that wind and other external factors have little or no influence on the burning of the candle.
  • the presence of flammable gases, such as natural gas or gasoline vapors, may be detected, and the flame extinguished so as to reduce the likelihood of igniting the gases.
  • a flame control system for a candle includes a cover or enclosure that defines an enclosed area arranged to house a candle having a burning flame for an extended period.
  • the cover may be air-tight in portions above the bottom, and may have an opening at a lower end to allow air to enter the enclosed area, and to allow combustion products from the flame to exit.
  • An air supply may provide air into the enclosed area, and the flame may be extinguished when the supply of air into the enclosed area drops below a threshold level.
  • a flame control system includes an enclosed area in which a burning flame of a candle is positionable, and an air movement device that causes air to be provided into the enclosed area for the burning flame.
  • the enclosed area may be constructed and arranged so that when the air is not caused to be provided into the enclosed area by the air movement device, the flame is extinguished, e.g., within 5 minutes, 1-2 minutes or less.
  • a flame control system includes a radial exhaust feature, e.g., to help disperse the exhaust gases produced by a burning candle. If the candle is scented or otherwise produces materials that the user would like to spread about a room or other space, the radial exhaust feature may help to disperse the scent or other materials more evenly and/or quickly.
  • a radial direction is one that approximately originates at the axis and is oriented generally away from an axis. In the case that the axis is arranged in a vertical direction, radial directions may be oriented generally away from the axis and each other, and may be arranged in a horizontal direction and/or at an angle to the horizontal.
  • the flame control system may include an enclosure that defines an enclosed area in which a burning flame of a candle is positionable approximately at a vertical axis.
  • a support may be constructed and arranged to support the candle with the burning flame positioned in the enclosed area, and exhaust outlets may direct exhaust from the enclosed area in at least two different radial directions relative to the vertical axis.
  • An air movement device may cause air to be provided into the enclosed area for the burning flame and cause exhaust from the enclosed area to move in the exhaust outlets.
  • the enclosure and the enclosed area may be arranged so that when the air movement device reduces a flow of air provided into the enclosed area below a threshold, the flame is extinguished within 5 minutes, within 1-2 minutes or less.
  • exhaust in the enclosed area may enter each exhaust outlet in a generally vertical direction and is directed in a direction radially away from the vertical axis.
  • the support may include a central region that supports the candle and the exhaust outlets may be at least partially formed by the support, which may include a plurality of exhaust openings arranged around the central region.
  • the support may also include a plurality of inlet openings that form inlets by which air is introduced into the enclosed area, and the inlet openings and exhaust openings may be alternately arranged around the central region and be positioned below the burning flame.
  • air may be introduced into the enclosed area so that the burning flame generally does not lean, is not “pushed” in one direction or another, and/or otherwise generally remains aligned with a vertical axis.
  • avoiding flame "push” may be achieved by introducing air into the enclosed embodiment from two or more radial directions into the enclosed area. The air may be balanced so that the candle flame generally remains vertical and is not "pushed.”
  • a flame control system may include an enclosure that defines an enclosed area in which a burning flame of a candle is positionable with the burning flame being positioned approximately at a vertical axis.
  • a support may be constructed and arranged to support the candle with the burning flame positioned in the enclosed area, and an air inlet may be arranged to provide air into the enclosed area for combustion by the flame.
  • An air movement device such as a fan, may cause air to be provided into the enclosed area via the air inlet for the burning flame, and the enclosure and the enclosed area may be arranged so that when the air movement device reduces a flow of air provided into the enclosed area below a threshold, the flame is extinguished within 5 minutes.
  • the air inlet may be constructed and arranged to introduce air into the enclosed area so that the burning flame remains generally aligned along the vertical axis while burning, e.g., the air inlet may include a plurality of ducts that direct air in a radial direction relative to the vertical axis into the enclosed area.
  • Air inlet openings may be arranged around a central region of the support that supports the candle, and may be alternately arranged with exhaust openings that exhaust gases from the enclosed area. Air may travel generally vertically, e.g., under the force of a fan, in the ducts and be directed in a radial direction to exit an inlet opening and enter the enclosed area.
  • air introduced into the enclosed area may reflects off of the enclosure and be directed back generally toward the flame.
  • a shield may be provided around the enclosure, e.g., to prevent touching of the enclosure which, although generally cooler than the flame, may still be warm to the touch.
  • a flame control system may include an enclosure that defines an enclosed area in which a burning flame of a candle is positionable with the burning flame being positioned approximately at a vertical axis.
  • a shield may be positioned around the enclosure and be arranged to prevent human hand contact with the enclosure.
  • the shield may also include vents to permit air to into a lower portion of the space between the shield and the enclosure and to permit air to exit an upper portion of the space, e.g., to allow cooling air to circulate in the space.
  • a support may be constructed and arranged to support the candle with the burning flame positioned in the enclosed area, and an air movement device may cause air to be provided into the enclosed area for the burning flame.

  • the cover may protect persons or flammable objects from contacting the flame.
  • Fig. 1 shows an illustrative embodiment of a flame control system 10 that incorporates various aspects of the invention.
  • a candle 1 is arranged within a cover 2 that defines an enclosed area in which the candle's flame may burn for an extended period, e.g., 1 minute, 10 minutes, 1 hour, or more.
  • the cover 2 may be made in any suitable arrangement, in this embodiment the cover 2 is made of glass and has a hemispherical, bowl-like or dome-like shape.
  • the cover 2 may be air-tight, e.g., include an upper portion with no holes or openings to allow air to pass.
  • the cover 2 defines a dome-shaped interior area having a volume larger than the enclosed candle with the bottom of the cover 2 having a diameter of approximately 2.5 inches and a height of approximately 3.5 inches.
  • the candle 1, which may be a tealight candle, may be placed inside the enclosed area of the cover 2 on a support 3 that has an air inlet 4 that allows air to enter into the enclosed area.
  • Air for combustion of the candle flame may be introduced into the enclosed area by way of an air movement device 5, e.g., a fan, moving air into the enclosed area. Exhaust gases generated by the candle flame may be exhausted via an exhaust outlet 7.
  • the enclosed area may be arranged so that the candle flame extinguishes if the air movement device 5 reduces the amount of air supplied through the air inlet 4 into the enclosed area below a threshold. That is, the fan 5 moves air through the air inlet 4 at a rate to provide sufficient air to keep the flame burning and exhaust combustion products through the exhaust outlet 7. If the fan 5 slows sufficiently or is stopped, the candle flame will extinguish, e.g., within 5 minutes, 1-2 minutes, or less, as a result of insufficient air for combustion.
  • a controller 6 may be used to control the operation of the fan 5 and/or perform other functions.
  • the controller 6 may include one or more switches (as shown) to control the power provided to the fan 5, e.g., a toggle switch that may be operated by a user to turn the fan on and off.
  • the controller 6 may control the operation of the fan 5 based on detected environmental conditions or any other suitable criteria.
  • the controller 6 may have a timer that a user may set for a desired burn period, e.g., 1 hour. The controller 6 may then allow the fan 5 to run for one hour, at which time the fan 5 may be turned off and the candle flame extinguished.

  • Fig. 3 is a cross-sectional side view of the Fig. 1 embodiment, but shows exhaust flow out of the enclosed area.
  • the fan 5 blows air upwardly toward a plurality of air inlet ducts 41, which each direct the air to move in a radial direction into the enclosed area of the cover 2 relative to a vertical axis 8 at which the candle flame is approximately located.
  • Each of the air inlet ducts 41 leads to an inlet opening 42 though which the air enters into the enclosed area.

  • the fan 5 blows air upwardly toward a plurality of air inlet ducts 41,
  • the air entering via the inlet openings 42 is directed radially away from the candle flame and toward the cover 2.
  • the air may contact the cover 2 and be reflected back toward the candle flame, and may create a turbulent environment in the enclosed area.
  • the air may be introduced to the flame in a more balanced way, thereby avoiding "push" of the flame (causing the flame to lean in a direction away from vertical), avoiding substantial leaning of the flame and/or other deviation of the flame from a direction aligned with the vertical axis 8.
  • the flame may burn the candle more evenly, creating less smoke and/or avoiding damage to the candle holder (i.e., a cup or other container in which the candle wax and wick are provided).

  • air is introduced into the enclosed area in radial directions that are close to the horizontal, but it should be understood that air may be introduced in any suitable direction relative to the horizontal.
  • exhaust gases produced by the candle 1 exit the enclosed area via exhaust ducts 71 that extend between exhaust openings 72 in the enclosed area and exhaust outlet ports 73 which are positioned around a periphery of the support 3. Pressure created by the introduction of air into the enclosed area forces the exhaust through the exhaust openings 72 and out the exhaust outlet ports 73.
  • exhaust enters the exhaust openings 72 in a generally vertical direction and is directed into a radial direction away from the vertical axis 8.
  • the exhaust is output from the ports 73 in a direction that is approximately horizontal, but the exhaust may be output in any suitable radial direction relative to the horizontal. As discussed above, radial exhaust output may help to disperse the scent or other materials produced by the candle 1.
  • the inlet and outlet openings 42 and 72 may be arranged in any suitable way, in this illustrative embodiment, the openings 42 and 72 are alternately arranged around a central region 31 of the support 3 as can be seen in Fig. 1. Such an alternate arrangement may aid in proper introduction of air into the enclosed area, mixing of gasses in the enclosed area or other features.
  • Other arrangements are possible, such as having inlet openings 42 arranged in and/or near the cover 2 so that air is introduced into the enclosed area in a radial direction toward the vertical axis 8.

  • Air movement caused by the fan 5, is generally upward initially and then the air is directed more horizontally and radially to exit the inlet openings 42.
  • Air entering the outlet openings 72 is directed to move radially outwardly from the openings 72.
  • This portion 32 of the support 3 may also form the central region 31 where the candle 1 is supported, i.e., on a side opposite that shown in Fig. 4.

Suitable arrangement of the vents 91 may allow for convective flow of air through the space, helping to keep the cover 2 and/or the shield 9 cool.
  • the exhaust ducts 71 do not vent into the space between the shield 9 and the cover 2, and the vents 91 for the shield 9 are separate from the exhaust outlet ports 73.
  • the shield 9 and the cover 2 may be attached to form an integral piece that is removably received on the portion 32 of the support 3. Thus, the shield 9 and cover 2 may be lifted from the portion 32, e.g.,. to allow replacement and/or lighting of the candle 1, and then placed on the portion 32 to enclose the candle 1.

  • products from the combustion of the candle can be more readily spread throughout a room or space in which the system 10 is located. This may be desired, particularly where the candle gives off a fragrance or other odor.
  • Another advantage that may be provided by various aspects of the invention is a relatively high resistance of the candle flame to being extinguished by high winds or other air movement outside of the enclosed area. Referring to the Fig. 1 embodiment as an example, high wind around the outside of the cover 2 and/or shield 9 cannot easily enter the enclosed area to affect the candle flame.
