Beverage Cooler and Heater

摘要

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 also includes a switch that activated or deactivated based on its proximity to a magnet in the table. The coaster has a metallic plate on which may be positioned a beverage container. The plate is thermally and mechanically coupled to a Peltier cell that either cools or heats the plate, depending on the state of the switch.

1. A beverage heating and cooling system comprising:
a beverage coaster having a first end, an opposing second end, a housing, a metallic plate connected to the housing at the first end, a Peltier cell within the housing mechanically and thermally connected to the metallic plate, a switch within the housing, a receiving coil located within the housing proximal to the second end, and coaster circuitry electrically connected to the Peltier cell, the switch, and the receiving coil; and a counter with a countertop having a top surface and a bottom surface, a magnet, a driving coil, and driver circuitry connected to the driving coil.
