Abstract:
A dual heater element for heating a liquid for use in a vending apparatus is provided. The heater element includes two elements. A first heating element is operable for use at a conventional first operating voltage or range (e.g., 120 VAC) while a separate second heating element is operable for use with a conventional second operating voltage or range (e.g., 230 VAC). A first pair of terminals coupled to the first heating element and a second pair of terminals coupled to the second heating element are selectively and/or interchangeably connected to a pair of line voltage terminals. The configuration of the line voltage electrical system and the use of a heater element with dual elements each operating (normal operation) at different voltages or voltage ranges allows the vending apparatus to be manufactured without variation in components and enables dual voltage source operation for two different line voltages (e.g., line voltage supply is either 120 VAC or 230 VAC).
