BEVERAGE HEATING SYSTEM
A system having a beverage coaster with a receiving coil that can be magnetically coupled or decoupled from a driving coil in a counter table, bar and the like. The coaster may be magnetically coupled to the table by moving the coaster into an area where the driving coil generates a magnetic field of sufficient strength. The coaster has a metallic plate on which may be positioned a beverage container. The plate is thermally and mechanically coupled to a power resistor that heats the plate and thus the beverage container.
1 . A beverage heating system comprising:
A beverage coaster having a first end, an opposing second end, a metallic plate connected to the first end, a power resistor within the housing that is mechanically and thermally connected to the metallic plate, a receiving coil located within the housing proximal to the second end, and coaster circuitry electrically connected to the power resistor and the receiving coil, and
A counter with a countertop having a top surface and bottom surface, a driving coil, and driver circuitry connected to the driving coil
2 . The system of claim 1 , wherein the driving coil is magnetically coupled to the receiving coil
3 . The system of claim 1 further comprising driver circuitry electrically connected to the driving coil.
4 . The system of claim 1 further comprising coaster circuitry electrically connected to the receiving coil and the power resistor.
5 . The system of claim 1 further comprising a USB port mounted to the housing and electrically connected to the coaster circuitry.
6 . The system of claim 1 further comprising an AC to DC converter connected to the receiving coil.
