Patent number: 7985934Abstract: 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: GrantFiled: February 22, 2006Date of Patent: July 26, 2011Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Rolf Schuck, Manfred Schulz, Andreas Ziemann
