  • Patent number: 12031727
    Abstract: A cooking appliance includes: a cooking cavity with a bottom wall and a rear wall. A convection fan is disposed adjacent to the rear wall of the cooking cavity. A gas burner is located in a subjacent space beneath the bottom wall and adjacent to the rear wall of the cooking cavity. A heat duct provides communication through the bottom wall and includes an inlet positioned directly above and adjacent to the gas burner through which combustion gases from the gas burner can enter the heat duct. An annular portion of the heat duct defines a pass-through opening in which the convection fan is disposed.

  • Patent number: 11957120
    Abstract: Torches are automatically refilled with a liquid fuel from a central reservoir pumped via a plumbing system, without directly monitoring local torch fuel levels. Instead, each torch includes a passive fuel overfill prevention valve. When refueling, the pump operates until all torches are filled. Refueling can cease after a set time, or when sensors report a backpressure and/or cessation of fuel flow. Pre-calibration establishes torch burning rates and/or maximum refill time. Time between refueling is predicted, based upon total burning time, which can be measured by torch heat sensors or determined according to a usage schedule or direct control of torch ignition and extinguishing by the controller. Reverse pumping can extinguish the torches, and wick ignitors can relight them sequentially. A service provider can monitor fuel consumption, establish a pattern of usage, and supply fuel in time to replenish the central reservoir, and/or other provide maintenance as needed.
