Publication number: 20120199571Abstract: Disclosed is a pressurized oven apparatus having a compressor and a pressurized chamber for rapidly preparing food products and retaining internal moisture therein. The apparatus comprises an oven with a pin-locking door and sealing means, an internal chamber having heating elements and a structure designed to withstand elevated internal pressures. Ambient air is drawn into the device through an air filter by an air compressor means. The compressor elevates the air pressure as it enters, whereby it flows to a preheating chamber, raising its temperature prior to being forced into the oven internal chamber. An automated relief valve system allows a consistent pressure to be maintained within the chamber, allowing the pressurized air to be evacuated therefrom through an insulated and muffled outlet. The air outlet of the device is preferably connected to an insulated air line to vent air to the exterior of a building or residence.Type: ApplicationFiled: January 5, 2012Publication date: August 9, 2012Inventor: Christopher Brown

Patent number: 8110779Abstract: There is provided a door lock control device in a heating cooker that prevents a door from being accidentally unlocked when the door is locked and a temperature inside the heating cooker is a predetermined temperature or more such as during self-cleaning. When the temperature inside the cooker is low and a thermal switch 8 of a lock detection and thermal switch portion 6 is closed, the lock detection and thermal switch portion 6 can be energized, and a power supply line 2 can supply power to a drive motor 5 to lock and unlock the door. In the case of self-cleaning or the like, the door is locked and a detection switch 7 is on a door lock side 7a, but the temperature inside the cooker is high and thus the thermal switch 8 is opened, and the power supply line 2 is interrupted.Type: GrantFiled: November 29, 2007Date of Patent: February 7, 2012Assignee: Sharp Kabushiki KaishaInventor: Masamitsu Kishimoto

Publication number: 20110023860Abstract: A device for latching of horizontal coke oven chambers which is triggered by an auxiliary frame located on the coke oven chamber door is provided. The auxiliary frame is restrictively movable in vertical direction on the coke oven chamber door. During the outward movement, the auxiliary frame hits upwardly against limit stop cams firmly mounted on the oven door and transmitting the vertical traction force onto the coke oven chamber door. During the upward movement, the auxiliary frame actuates levers which are rotationally movable to an axis arranged orthogonally to the coke oven chamber and which are connected to a translatorily freely movable latch. On actuation of this lever, it pulls the latch from the latch take-up bearings mounted on the coke oven chamber door so that the coke oven chamber door is unlatched and opened. In an embodiment of the present invention, the coke oven chamber door can be arrested in the open or closed position with a device suitable for this purpose.Type: ApplicationFiled: November 13, 2008Publication date: February 3, 2011Applicant: UHDE GmbHInventors: Franz-Josef Schuecker, Peter Thomas

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.

Publication number: 20100206289Abstract: 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: ApplicationFiled: May 3, 2010Publication date: August 19, 2010Applicant: WHIRLPOOL CORPORATIONInventors: CHRISTOPHER A.
