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.

An indication device for a laundry washing machine, the washing machine comprising:
- a treatment chamber (12) for laundry with an opening (13) which in a treatment position is covered by a door (16) fixed to a surrounding housing (11) and is sealed from the housing by means of sealing arrangement, and the chamber (12) is pressurized to treat laundry with a cleaning agent, and the sealing arrangement comprises at least two gaskets (19, 20) surrounding the opening and forming an intermediate space (23) which via a channel (24) is arranged to communicate with atmosphere such that a sound indication is achieved by gas entering into the intermediate space and flowing through the channel to atmosphere if there is a gas leakage into the intermediate space.
An indication device according to clam 1, wherein the channel (24) is designed such that it serves as a restriction for out flowing gas.
An indication device for a laundry washing machine comprising:
- a treatment chamber for laundry;
- an opening in the treatment chamber;
- a housing surrounding the treatment chamber;
- a cover for the chamber opening;
- and
- a sealing arrangement engaging the chamber opening and the cover to seal the chamber from the housing when the chamber contains pressurized gas, the sealing arrangement comprises at least two gaskets surrounding the opening, an intermediate space formed between the at least two gaskets, and a channel connecting the intermediate space to atmosphere, wherein the channel is designed to serves as a restriction for out flowing gas, and
- wherein gas leaking into the intermediate space flows through the restriction and produces an audible sound indicating there is gas leakage from the treatment chamber.
