Title: BEVERAGE WARMER
Abstract:
Known beverage warmers are automatically energized by the weight of a container with liquid in it when supported on an electrically heated surface and are deenergized by a heat sensitive element.The present beverage warmer selectively warms a beverage when a beverage container is positioned on a support surface in a particular orientation. In a preferred form, the present beverage warmer for selectively energizing and warming comprises a support 19 (43) of non-magnetic material providing an upwardly facing heating surface 21 (49), an electrical heating element 22 (45) disposed to heat the surface, an energizing electric circuit for the heating element including a normally open magnetic switch 26 (46) mounted in a predetermined location on the support below the surface, and a separate beverage container 12 (51) adapted to rest on the surface of the support being essentially of non-magnetic material and having a permanent magnet 44 (54) fixed to a lower portion thereof whereby to cause the magnetic switch to close and the electrical heating element to energize only when the container is oriented to dispose the magnet effectively adjacent the magnetic switch.
