Patent number: 10730008Abstract: A device for the dehumidification of air in a processing space of a dishwasher is connected in an air-conducting manner to the processing space of the electric appliance. The device includes carbon-based fibres, which are designed as a fibre unit. The fibre unit is arranged between the processing space or an air duct connected thereto and at least one dehumidification chamber of the device. The carbon-based fibres absorb moisture from the air of the processing space, which they then release again in the dehumidification chamber. During this process, the carbon-based fibres are moved backwards and forwards between the processing space or air duct and the dehumidification chamber, preferably by slow rotation on a support.Type: GrantFiled: February 5, 2018Date of Patent: August 4, 2020Assignee: E.G.O.

Patent number: 7946220Abstract: A method for regulating a cooking process of a cooking product in an oven of a steamer, during which the moisture in the oven coming from the cooking product is at least periodically determined over time by a moisture sensor. During a measuring phase there is no introduction of steam into the steam oven and the moisture sensor is evaluated. For a given cooking process with fixed times for the supply of steam, on the basis of the moisture sensor evaluation during the measuring phase, the end of cooking is determined. Prior to the measuring phase and during a steam phase, steam is introduced into the oven, the steam supply being terminated following the steam phase and prior to the measuring phase during a ventilating phase. During the ventilating phase the steam concentration in the oven is greatly reduced.Type: GrantFiled: March 26, 2008Date of Patent: May 24, 2011Assignee: E.G.O.

Patent number: 7812288Abstract: A sensor for a sensor device on a cooking hob is provided with contacts on a support, an electronic circuit for signal processing and a resistance track for temperature measurement. The sensor is arranged in a tubular metallic housing above a radiant heater of the cooking hob. The metallic housing is operated as an electromagnetic pan recognition sensor. The functions of temperature measurement and pan recognition can be combined in one sensor device as a module. A good transmission of sensor signals can be achieved as a result of the physical proximity of the sensor signal processor to the sensor by placing them on the same support.Type: GrantFiled: December 20, 2007Date of Patent: October 12, 2010Assignee: E.G.O.
