Abstract
A low wattage slow cooker featuring a wrap-around heating element for heating the side walls of the cooking vessel and a top heating element for browning food items is disclosed. The top browning element is integrated into a lid assembly of the cooker and is provided with quick connect/disconnect electrical connectors, which provide for convenient removal of the lid assembly for food service, cleaning, and storage. The wrap-around heating element and the top heating element are interconnected by a controller for heat regulation and selectively energizing the desired heating elements individually or in combination. The wrap-around heating element and the top heating elements are constructed in alternative embodiments utilizing different configurations of resistance wiring for versatility in manufacturing and cooking applications. All embodiments of the present slow cooker are provided with a heatproof ceramic or glass cooking liner, which acts as an heat insulator.
