Publication number: 20100218394Abstract: A front-loading clothes dryer, a horizontally pivotable door is secured in its closed position against accidentally opening by a latching closure. Moreover, the door is connected to a safety switch which cuts off or re-establishes power supply for the clothes dryer depending on whether the door is in the open or in the closed position. The object of the invention is to ensure that the switching function remains matched over the long term to the closure state of the door, as when the clothes dryer was manufactured. For that purpose, the functional elements for the latching closure and safety switch are arranged in direct proximity to each other but functionally separated into a component arranged on the door and a component arranged on the casing.Type: ApplicationFiled: February 22, 2006Publication date: September 2, 2010Applicant: BSH Bosch und Siemens Hausgeräte GmbHInventors: Rolf Schuck, Manfred Schulz, Andreas Ziemann

Patent number: 7748897Abstract: A method for monitoring the proper functioning of a temperature-dependent resistor, particularly a NTC resistor, for measuring the temperature of a medium heated by a heat source. Said medium is preferably the air flow in a clothes dryer for drying clothes. In order to increase the safety of a device, in particular a clothes dryer, where the temperature-dependent resistor is used in combination with a heat source, it is checked, once the heat source is switched on, whether the temperature measured by the resistor after a first predetermined period of time following the switching on of the heat source falls below a predetermined temperature threshold value. If this is the case, monitoring of a resistor-temperature curve characteristic of the temperature-dependent resistor is carried out.Type: GrantFiled: February 8, 2006Date of Patent: July 6, 2010Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Kai-Uwe Bache, Thomas Nawrot, Ulrich Nehring, Andreas Ziemann
