Abstract
A beverage heating and cooling device has at least one removable beverage container holding chamber. Each chamber has a spring mechanism assembly to bias a beverage container against a heat transfer member protruding through the chamber-side-wall opening. An electronic controller controls the operation of a thermoelectric heating and cooling element connected to the heat transfer member. The controller has a thermal fuse to protect the device from overheating in the event that the thermal switches fail to maintain the heat transfer member at a desired temperature range. When used in a motor vehicle with the ignition off, an automatic timer within the controller shuts off the unit after a predetermined time to conserve power.
