Title of Invention:

Variable wattage drip tray heater

Invention Abstract This invention provides for the modulation of the heater wattage by various means to allow the use of a single heater part to provide differing wattages to address the need to evaporate water from the water dispenser tray

Problem or requirement addressed by the invention The dispenser water dispenser, being wet and having a spout that empties after each dispense, drips water into the drip tray below. In addition, it is advantageous to provide a common heater to all product within a manufacturing line, in order to reduce part count.

How the invention works This invention provides for the modulation of the heater wattage located in the water sump under the water spout by various means to allow the use of a single heater part to provide differing wattages to different products as needed. Possible embodiments include: 1) modulation by duty cycle 2) Modulation by applied voltage 3) Variable wattage based on refrigerator size 4) Variable wattage based on frequency of ice dispense 5) Variable wattage based on frequency of ice harvest 6) Variable wattage based on control setting 7) Variable wattage based on refrigerator run time 8) Special wattage applied as a service fix 9) Variable wattage based on humidity sensor 10) Variable wattage based on freezer temperature

Important features of the invention and how it solves the problem above: Allows a single part to be used to solve water dripping in all...
