Heat exchange method for melting plate candle
First Claim
1. A candle comprising a meltable solid fuel element, a melting plate upon which the fuel element rests, and a wick holder comprising an upwardly extending wick carried by a wick holding means and heat conductive fins, wherein at least one of the heat conductive fins extends upwardly above the wick holding means and is positioned so as to collect heat from a flame upon the wick and to conduct such heat to the fuel element and to the melting plate, the wick holder engaging the meltable solid fuel element, and the heat conductive fins being insulated so as to prevent loss of the heat to the atmosphere.

Abstract
The present invention relates to melting plate candles which employ heat conductive elements to distribute heat from a burning flame at a wick to a support plate for a solid fuel and to the body of said solid fuel, so as to more rapidly liquefy the solid fuel, such as paraffin wax, and to more uniformly and intensely heat such fuels to increase the efficiency of consumption thereof and to more rapidly release volatile materials contained within said fuels. The heat conductive support plate is configured so as to have a capillary pedestal upon the surface thereof, which cooperatively engages a wick holder comprising a preferably consumable wick and heat conductive fins which conduct heat from a flame upon said wick to said support plate, said wick holder further engaging said capillary pedestal in such a locking manner as to resist accidental removal from said pedestal. The fuel may be provided in various forms, configured to cooperatively engage said wick holder and support plate, and may comprise various volatile materials. The capillary pedestal, in conjunction with the wick holder, causes rapid and complete flow of the liquefied fuel to said wick.

- 1. A candle comprising a meltable solid fuel element, a melting plate upon which the fuel element rests, and a wick holder comprising an upwardly extending wick carried by a wick holding means and heat conductive fins, wherein at least one of the heat conductive fins extends upwardly above the wick holding means and is positioned so as to collect heat from a flame upon the wick and to conduct such heat to the fuel element and to the melting plate, the wick holder engaging the meltable solid fuel element, and the heat conductive fins being insulated so as to prevent loss of the heat to the atmosphere.
- 9. A candle comprising a meltable solid fuel, a support plate upon which the fuel rests, and a pedestal defined by the support plate which cooperatively engages the base portion of a wick holder comprising a wick, the wick holder conducting heat from a flame upon the wick to the solid fuel and the support plate by means of heat fins which contact the flame, the fins being insulated so as to inhibit heat loss between the flame and the solid fuel.
- 14. A candle comprising a fuel holder comprising a heat conductive surface shaped to hold and melt a solid fuel material included in a replaceable solid fuel element further comprising a wick holder including a wick and heat fins, and to form a pool of liquid fuel, the surface further comprising a capillary pedestal which lockingly engages the wick holder, wherein the heat fins are configured so as to come in close proximity to a flame on the wick and to conduct heat from the flame to the fuel element, the tips of the heat fins being connected by heat conductive means passing directly through the flame, and wherein the surface is shaped so as to cause the pool of liquid fuel to flow to the wick.
- 18. A replaceable fuel element for a melting plate candle, the fuel element comprising a solid fuel material cooperatively engaging a wick holder comprising a wick, the wick holder configured so as to lockingly engage a capillary pedestal on the melting plate candle, and further comprising heat fins which pass through a flame upon the wick and conduct heat from the flame to the fuel element by means of branches which extend outward from the fins into the fuel element.

20. A replaceable fuel element for a melting plate candle, the fuel element comprising a solid fuel material cooperatively engaging a wick holder comprising a wick, the wick holder configured so as to lockingly engage a capillary pedestal on the melting plate candle, and further comprising heat fins which pass through a flame upon the wick and conduct heat from the flame to the fuel element by means of branches which extend outward from the fins into the fuel element, wherein the fins are insulated in a limited area between the flame and the branches and inhibit heat loss between the flame and the solid fuel.
