Abstract: An indication device for a laundry washing machine, which has a treatment chamber (12) for laundry that can be pressurized in order to treat the laundry with a cleaning agent. The treatment chamber is provided with an opening (13), which in the treatment position is covered by a door (16) fixed to a surrounding housing (11) and is sealed from the housing by means of a sealing arrangement. The sealing arrangement comprises at least two gaskets (19, 20) surrounding the opening and forming an intermediate space (23) that via a channel (24) is arranged to communicate with atmosphere.

Abstract: A safety device for a laundry washing machine or the like where the washing machine comprises a treatment chamber (12) for laundry that is pressurized in order to treat the laundry with a treating agent, for instance, carbon dioxide. The treatment chamber has an inlet opening (13) which during the treatment is covered by a door (16) that is secured to a housing (11) enclosing the chamber by means of a first holder device (35) which is part of a locking means. The locking means also comprises a second holder device (34) which is activated if the first holder device (35) is deactivated and thereby keeps the door (16) in its closed position as long as chamber is pressurized.
