Patent number: 8766143Abstract: A method for operating a cooking appliance having a cooking appliance control system and a door. The method includes automatically opening the door using the cooking appliance control system when a cooking process is complete, and automatically closing the door when a physical quantity falls below a predetermined threshold value stored in a memory of the cooking appliance control system. In addition, a cooking appliance includes a cooking chamber, a door, a cooking appliance control system having a memory, a sensor disposed in the cooking chamber, a guide device, and a door opening device including a positioning motor and a rod. The cooking appliance control system is configured to actuate the positioning motor as a function of the output signal so as to automatically open the door when a cooking process is complete and automatically close the door when a physical quantity falls below a predetermined threshold value.Type: GrantFiled: January 24, 2005Date of Patent: July 1, 2014Assignee: Miele & Cie. KGInventors: Uwe Berger, Hartmut Dittrich, Ruediger Hoehn

Patent number: 8285128Abstract: A steam generator for a household appliance. The steam generator includes an evaporation chamber having a substantially planar evaporation surface with first and second sections. A water supply line is in fluid communication with the evaporation chamber and a steam discharge line is also in fluid communication with the evaporation chamber. The steam generator includes a heat accumulator configured to heat the evaporation surface. At least one of a valve and a pump is associated with the water supply line and operable to control an introduction of water into the evaporation chamber. An electric controller controls the heating of the heat accumulator by the heater and the introduction of water into the evaporation chamber using the at least one of valve and pump. The first section of the evaporation surface is a starter section that is thermally conductively coupled to the heat accumulator such that heat flow from the heat accumulator to the starter section is limited compared to the second section.Type: GrantFiled: April 10, 2008Date of Patent: October 9, 2012Assignee: Miele & Cie.

Patent number: 7638736Abstract: A method for steam cooking includes introducing steam, from a steam generator device, into a food cooking container through a supply conduit so that at an inlet opening to the food cooking container the steam enters tangentially to a wall of the food cooking container. The generation of steam is controlled by a control system so as to provide a difference between the pressure in the supply conduit and the pressure in the interior of the food cooking container of at least 1 kPa.Type: GrantFiled: September 26, 2006Date of Patent: December 29, 2009Assignee: Miele & Cie. KGInventors: Juergen Adamczak, Uwe Berger, Hartmut Dittrich, Thomas Metz, Dirk Telthoerster, Stefan Homburg

Publication number: 20070045278Abstract: A glass ceramic cooktop includes at least one burner delimited in a radial direction by an inner wall of insulation, and a heating element disposed under the burner for heating up a cooking pot placed on the burner. A monitoring element is provided for limiting a heating temperature to a maximum value and to limit heat generated underneath the glass ceramic surface so as to limit heat radiated on the glass ceramic surface to a predefined value. A temperature switch is disposed underneath the glass ceramic surface outside of the burner in the radial direction. The temperature switch is configured to sense radially radiating heat released outside of the burner and, within a range of from about 130° C. to about 200° C., switch off the heating element.Type: ApplicationFiled: August 21, 2006Publication date: March 1, 2007Applicant: Miele & Cie.
