Abstract: The present invention relates to drinks dispense equipment having an ice dispensing capability. A drip tray is secured to such a dispenser and the drip tray has an electrical heating element secured directly to a bottom surface thereof. The heating element consists of a specialized printed circuit having a flexible plastic base having a positive temperature coefficient (PTC) electrical heating element printed on one surface thereof.

In operation, as ice accumulates on the drip tray, the heating element is cooled causing an increase in the heat output thereof, thereby melting the ice. Once the ice has melted the heating element will reduce the flow of current as the temperature thereof warms to ambient.
