A cooking control system accesses a set of training data used to train a machine learned model configured to detect smoke in a kitchen environment based on image data of a stovetop. The cooking control system receives real-time image data of a stovetop from a camera in the kitchen environment and applies the machine learned model to the image data to determine a likelihood that the image data includes smoke. If the cooking control system determines that the received images contain smoke, the cooking control system may perform one or more actions, such as disabling operation of the stovetop and sending an alert indicative of smoke to a user of he cooking control system or a local emergency department.

An adjustable camera assembly mounted within a door of an oven appliance includes a vertical guide rail and a camera movably mounted to the guide rail. A drive mechanism, such as a lead screw driven by a stepper motor, is mechanically coupled to the camera for moving the camera along the guide rail. A heat shield is positioned proximate a bottom of the door and extends around the guide rail to define a protective cavity for receiving the camera and providing a thermal break from a heating element of the oven appliance. A controller is configured for moving the camera into the protective cavity during high temperature operation of the oven appliance, such as during a self-clean cycle.

An integral high pressure rapid quenching vacuum furnace utilizing an electrical isolation transformer in the blower motor power control system in order to isolate the motor windings, reduce the possibility of gas ionization and eliminate ground faults, particularly when quenching in argon gas, is described. In order to achieve the desired mechanical properties of certain metal alloys being quenched using argon gas as a quenching medium in the high pressure gas vacuum furnace chamber, a 600 HP460 Volt motor is required. A 460 Volt primary460 Volt secondary [delta-delta] isolation transformer, having input and output windings separated by an electrostatic shield connected to ground is placed between the power source and the gas blower motor in the quenching chamber filled with argon gas. The 460 Volt power source is connected to a variable frequency drive (VFD) and the VFD is connected to the primary transformer winding. The secondary transformer winding connects 460 Volts to the blower motor windings. The full electrical isolation of the transformer secondary winding results in zero ground fault voltage.

A safety auditor is designed to perform opening and closing of every safety switch that is used in an industrial bakery oven. Every pressure sensor can be tested for on and off states. The low gas pressure switch can be vented and the high gas pressure switch pressurized. All thermocouples associated with the high temperature circuits are tripped. Fans are started and stopped over a communications signal or via the hard-wired interface as required to generate the safety testing. Once the safety testing is complete, the results along with time, date, name of tester, pass or fail will be printed out via a small kiosk printer. This ticket can then be filed in an office. As the operation is easy to do and requires little effort, it is much more likely to be performed and therefore safer for the host bakery.
