Abstract

A tumble dryer includes a drum receiving laundry to be dried and a container accommodating an extinguishing agent, with the drum and the container being connected by a first line. A first temperature-activated valve is arranged in the first line in thermal contact with the interior of the drum and provided to close the container and to open automatically at a temperature produced by a fire. Further connected to the container is a second line which has a mouth feeding into a region of a base plate of the tumble dryer. A second temperature-activated valve is configured to close the second line in a region of the mouth and to open automatically at the temperature produced by the fire. The first and second valves are hereby positioned in such a way that either the first valve or the second valve opens automatically at the temperature produced by the fire.
