Abstract
A temperature controlled food storage unit is provided with a Peltier device (18) to effectuate the temperature of food place in a thermally conductive container or basin (24). Air from a fan (52) is passed through an air duct (50) and over a heat sink (22), which is thermally coupled to one side of the Peltier device (18). A hand-operated damper (54, 64) is used to control the air flow through the air duct (50) and over the heat sink (22) thereby controlling heat exchange between the Peltier device (18) and ambient air.
