Abstract
Abstract A frying apparatus includes a support housing, an open top fat container, heating means for heating the fat in the container, and an escutcheon mounted above and behind the fat container. A thermostat, mounted in the escutcheon, is operatively connected to the heater for controlling energization of the heater. An electric motor unit is operatively connected to the thermostat for adjusting the setting of the thermostat upon energization of the motor. There is a circuit for connecting the motor unit to a suitable source of electric energy, including a manually operable switch. The switch is mounted in the housing forward of the open fat container.
