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.

Tumble dryer with passive extinguishing system

A device that has a component within a process air circuit of a washer dryer or tumble dryer; a condensate water trough in which condensate water is collected that is formed in the process air circuit as a result of drying damp laundry; and a first lever arm rotatably fastened to a rinse tank above the component. The component is to be cleaned and the condensate water is conducted from the condensate water trough to the rinse tank. Further, the condensate water is dispensed from an outlet opening of the rinse tank to the component. The rinse tank has a closure to selectively open and close the outlet opening and an actuator to actuate the closure. Also, the closure has a sealing head that is connected to the first lever arm and that closes the outlet opening.

A cleaning diffuser is disposed above a fluff-laden component and receives rinsing fluid for distributing the rinsing fluid to the fluff-laden component to detach fluff and carry it away. The diffuser is constructed to enable a buildup of dynamic pressure in the rinsing fluid and has two feed ducts which extend at a distance from one another in substantially parallel relationship so that rinsing fluid entering the diffuser is divided between the feed ducts. The feed ducts terminate in pockets in a wall at an end of the diffuser and have, relative to their entire duct length, a narrow, three-dimensional transverse mutual connection in the form of a transverse chamber. The diffuser has at least one narrow outlet opening which extends from the three-dimensional transverse connection to a lower side of the diffuser for distributing the rinsing fluid to the fluff-laden component.
