Patent number: 8336535Abstract: A cooking appliance includes an oven cavity accessed through first and second French-style doors that are connected to the appliance through a door linkage system. The door linkage system establishes a particular timing of door openings and closings to minimize potential wear of a door gasket. That is, each of the doors has an associated gasket for use in sealing the oven cavity when the doors are closed. One of the doors is provided with an annular gasket, while the other door essentially incorporates a less that fully annular, preferably 3-sided or a three-quarter gasket. With this arrangement, each of the gaskets has three sides adapted to seal against a cabinet shell portion of the appliance, while the fourth side of the first gasket is adapted to seal against an extension provided on the other door.Type: GrantFiled: July 13, 2006Date of Patent: December 25, 2012Assignee: Whirlpool CorporationInventors: Christopher A.

Patent number: 8327835Abstract: A cooking appliance having first and second oven doors that combine to extend across and close off a frontal opening of a cooking chamber includes a latching mechanism for locking the first and second oven doors in a closed position. The latching mechanism includes a fixed support plate and a motor having an output shaft to which is rotatably mounted an eccentric drive member. Preferably, the motor is fixedly mounted to the support plate. The latching mechanism further includes first and second latch members each having a first end portion pivotally attached to the eccentric drive member extending to a second end portion defining a hook element. When the motor is activated, a guide mechanism directs the second end portions of the first and second latch members to a locking position leading the hook members into engagement with the first and second doors.Type: GrantFiled: May 3, 2010Date of Patent: December 11, 2012Assignee: Whirlpool CorporationInventors: Christopher A.

Patent number: 7874289Abstract: A cooking appliance includes an oven door having a transparent zone and a passage for permitting an air flow to pass through the door and into a cooling duct extending about an oven cavity. The door includes a panel having a front surface and a central opening in which is arranged an outer transparent pane. The passage separates the outer transparent pane from an inner window pack. The inner window pack includes first and second, substantially parallel window panes spaced one from the other to establish an inner dead air space. Preferably, the door includes an inner transparent pane that forms, with an outer transparent pane, an outer window pack which establishes an outer dead air space. The outer dead air space is positioned between upper and lower portions of the oven door that establish additional dead air spaces that form an overall uniform insulating layer for the door.Type: GrantFiled: March 29, 2005Date of Patent: January 25, 2011Assignee: Maytag CorporationInventor: Christopher A.

Patent number: 7814897Abstract: A cooking appliance includes first and second French-style doors connected through a door linkage system. The door linkage system includes first and second control arms, each including a first end linked to a corresponding one of the first and second doors and a second end. The second ends of the first and second control arms are interconnected and mounted so as to travel in an arcuate path when one of the doors is operated. Shifting one of the first and second doors in an open or closed direction results in a corresponding movement in the other door. The first and second control arms are actually interconnected to a linkage control arm that establishes a particular timing of the doors. The door linkage system also employs a camming surface, cam follower and spring element that provides a biasing force to the doors.Type: GrantFiled: August 18, 2005Date of Patent: October 19, 2010Assignee: Maytag CorporationInventor: Christopher A. Larsen

Patent number: 7743762Abstract: A cooking appliance includes an oven cavity, a trim element and a door designed to pivot about a substantially vertical axis. The door is mounted for pivotal movement relative to the oven cavity about a substantially vertical axis. The door includes a main body portion having a front surface, a rear surface and a peripheral edge portion. The peripheral edge portion includes top, bottom and opposing side edge sections, with each of the opposing side edge sections leading to an extended region that overlaps, at least in part, the trim element. The extended region includes a generally rounded portion directly adjacent to the trim element. The generally rounded portion provides clearance necessary to enable the door to shift between open and closed positions, while simultaneously allowing the use of an extremely thin or low profile door.Type: GrantFiled: March 22, 2005Date of Patent: June 29, 2010Assignee: Maytag CorporationInventor: Christopher A.

Patent number: 7411160Abstract: A convection cooking appliance includes a convection fan for establishing a convection airflow which is heated by a heating element including first and second sections that are symmetrically disposed about the convection fan substantially parallel to and downstream of the convection fan. Each of the first and second sections is formed so as to include at least three lobes and four 180° turns, while establishing a thin profile heating element. A convection fan cover extends across the convection fan and includes a main body portion having an outlet portion for directing the convection airflow into a cooking chamber of the appliance. The outlet portion includes an angled louver and a trip edge portion. The angled louver and trip edge portion cooperate to alter a direction of the convection airflow from being substantially parallel to the main body portion to being substantially perpendicular the main body portion.Type: GrantFiled: July 20, 2005Date of Patent: August 12, 2008Assignee: Whirlpool CorporationInventors: Thu-Ha Duncan, Christopher A.

Patent number: 6895953Abstract: A gas cooking appliance includes at least one oven cavity which is coated with a heat resistant material, preferably porcelain. The cooking appliance includes a gas broil element and an associated baffle, as well as a gas igniter, arranged atop the oven cavity. The baffle is provided with one or more openings above the igniter for ventilation purposes. Each opening is preferably defined by a louver. With the inclusion of the louvered opening, enhanced combustion is assured and any potential crazing zone of the oven cavity is shifted to a position wherein, should any heat resistant material chip off due to heat from the igniter, the material will be blocked from falling into any food support zone of the oven cavity.Type: GrantFiled: March 12, 2003Date of Patent: May 24, 2005Assignee: Maytag CorporationInventors: Christopher A. Larsen, Gerald R. Place, Steven M. Swayne, Dutch VanZandt
