Abstract

An electronically controlled warmer with a user interface, a venting/cooling system, a fan, and an element uses one or more seals to protect objects in the chamber from the elements and facilitate use outdoors. The system is controlled by way of a user interface that interacts with the electronic control system to operate the heating elements. A sensor or sensor system sends signals to the electronic control system that then regulates the venting system and fans. The drawer has programmable operations, functions, and numerous set points.
