Patent number: 7126088Abstract: A control system for a cooking appliance enables a consumer to selectively program a cooking appliance through a control panel in a conventional mode based on established cooking times and temperatures, as well as in a simplified mode incorporating a minimal number of programming steps. In the simplified mode, the consumer selects a first, non-temperature related special features button and inputs a cook time. Immediately following input of the cook time, the control system starts a cooking operation. If the selected time is greater than a predetermined value, the control system automatically operates the cooking appliance in a cold start mode. An override is provided to disable the cold start mode if so desired. In addition, the control system allows a consumer to input both minimum and maximum cook times for the cooking operation.Type: GrantFiled: September 30, 2004Date of Patent: October 24, 2006Assignee: Maytag CorporationInventors: Willard Henry Horton, Kenneth E.

Publication number: 20030213371Abstract: A control system for a toaster oven incorporating a conveyor driven by an inexpensive ac motor, where the control system allows the entire range of toasting demands to be met while also compensating for variations in the line voltage. The heart of the toasting control is the reliance on the total dwell time of the bread products within the toasting zone of the oven, rather than on the speed of the motor. The control system also provides for a convection fan of varying speed without the need to replace the inexpensive muffin fan with more elaborate devices. Among the advantages offered by the dwell time approach is on-the-fly adjustment upward or downward of the degree of toasting, there being no need to await for the toasting zone to heat up or cool down to achieve this.Type: ApplicationFiled: May 13, 2003Publication date: November 20, 2003Inventor: David N. Saunders

Publication number: 20020113054Abstract: A vertical toaster comprising a housing, heating elements, a food support and a drive. The heating elements are connected to the housing and comprise at least one calrod. The calrod comprises an electric wire surrounded by heat conductive electrical insulation and a metal cover. The food support is movably mounted to the housing for up and down motion. The drive is for moving the food support relative to the housing. The drive comprises a motor and a linkage between the motor and the food support for moving the food support both down and up such that food on the food support passes by the calrod. The calrod prevents an electrical shock to a user if the user accidentally contacts the calrod with an electrically conductive member.Type: ApplicationFiled: February 16, 2001Publication date: August 22, 2002Inventors: Robert W.

Publication number: 20020104443Abstract: An automatic bread making machine having a baking chamber and a container for receiving bread making ingredients is provided with a backing rack assembly that is selectively placed into and removed from the baking chamber. The baking rack assembly is provided with a frame and a plurality of trays coupled to the frame, in vertically spaced relation to each other. Each of the frames provides a substantially horizontal support surface for a quantity of dough that can be proofed or baked on the tray when the rack assembly is positioned within the baking chamber. A user may therefore bake a plurality of portions of dough within a unitary chamber of an automatic bread making machine.Type: ApplicationFiled: April 14, 2000Publication date: August 8, 2002Inventor: Barbara Westfield

Publication number: 20020073851Abstract: A controllable electric toasting apparatus primarily for use in the home permits power to be safely disconnected when items become jammed inside. In addition, a carriage assembly inside the toasting apparatus can be raised during a toasting cycle so that the items can be viewed without interrupting the toasting cycle. Also, if an item is smaller than usual and placed in the toasting apparatus, the carriage assembly can be raised beyond its initial raised position to allow convenient removal of the small item.Type: ApplicationFiled: December 14, 2000Publication date: June 20, 2002Inventors: C.

Patent number: 6401599Abstract: The present invention relates to an automatic bread maker for home use, and particularly relates to methods of displaying during the bread making cycle. The automatic bread maker of the present invention comprises: a baking chamber with a heater, a baking pan disposed inside the baking chamber, a kneading blade disposed in the baking pan, a motor which drives the kneading blade, a controller which controls the heater and the motor, an input means for inputting cooking conditions, and a display which displays a time remaining before the time to add additional ingredients and the actual time to add the ingredients. The display shows the remaining time or the actual time to add the ingredients. Therefore, the user can clearly confirm when to add additional ingredients, and can prepare the ingredients accordingly.Type: GrantFiled: May 7, 2001Date of Patent: June 11, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Toshikatsu Maeda, Akihisa Nakano

Patent number: 6382084Abstract: In an otherwise well-known electric pop-up toaster, an auxiliary power switch is provided and is arranged to be opened by a timer after each toasting cycle. This ensures, in contrast to the well-known toaster arrangements, that power is interrupted to heating elements even if a carriage supporting slices of toast fails to move up at the end of a toasting cycle.Type: GrantFiled: June 5, 2001Date of Patent: May 7, 2002Assignee: Simatelex Manufactory Co., Ltd.Inventors: Stephen Wai-Kin Chan, Wing Chung Li

Patent number: 6380520Abstract: A safety shut-off device for an electric toaster having a food support member includes at least one switch that is movable between a closed position to thereby energize one or more heating elements associated with the toaster and an open position for deenergizing the at least one heating element. A rotatable support beam is pivotally connected to the chassis. An armature is connected to one end of the beam and a first locking member is connected to an opposite end of the beam. A second locking member associated with the food support member engages the first locking member during a toasting operation. During a toasting operation, the beam is rotated to close the at least one switch and an electromagnet is energized to hold the beam, and thus the food support member, in a toasting position. At the end of the toasting operation, the electromagnet is deenergized, causing the beam to rotate and open the switch to deenergize the at least one heating element and release the food support member.Type: GrantFiled: June 22, 2001Date of Patent: April 30, 2002Assignee: Hamilton Beach/Proctor-Silex, Inc.Inventor: Nhiem Viet Nguyen
