Patent number: 8224892Abstract: An improved oven for use in a residence is described. The oven includes a cooking chamber, a programmable controller for executing program instructions, memory media for recording executable program instructions, and at least one controllable cooking system under control of the programmable controller, which provides a data-processing-controlled high speed cooking process which may be applied to food placed in the oven chamber. A plurality of cooking programs are recorded in the memory media of the oven. These define a plurality of high speed cooking routines available for use with the oven. A gateway server is communicatively coupled to the programmable controller. It manages the communication of digital content which is at least in-part related to operation and utilization of the improved oven. A broadband communication channel extends from a source of digital content, which is external to the residence, to the residence.Type: GrantFiled: December 24, 2008Date of Patent: July 17, 2012Assignee: Turbochef Technologies, Inc.Inventors: Jeffrey Bogatin, Richard Caron, David McFadden, Bryan Connell, Carl Pryor, James K.

Patent number: 7956304Abstract: A combination switch is provided for a high-speed oven, the oven having a door. The combination switch has a rotatable cam (40) that is rotated when the door of the oven is moved between a closed position and an open position. The cam (40) has at least one lobe (50, 52) for engaging at least one safety-switch (44, 46) for actuation by the at least one lobe of the cam as the cam rotates. The at least one safety switch controls operation of at least a portion of the oven. A locking latch (48) is selectively moveable between an engaged position, in which the latch engages the cam (40) to limit rotation of the cam and thereby prevent opening of the door, and a disengaged position, in which the latch (48) does not engage the cam (40) and thereby allows opening of the door.Type: GrantFiled: November 8, 2006Date of Patent: June 7, 2011Assignee: Turbochef Technologies, Inc.Inventors: Carlos Bacigalupe, Michael J.
