A control and information system is for a lavatory of an aircraft, where the lavatory has a door. The system contains a door actuator for opening and closing, a lock actuator for locking and unlocking the door, a control device for controlling the door actuator and the lock actuator, a human-machine interface for actuating the door by a user, as well as a communication interface for exchanging information between an authorized entity and the control device. The lavatory contains a wall structure supporting the door, and the control and information system. A user controls the door via the human-machine interface. Information about the communication interface is exchanged between the control device and the authorized entity.

An example system for deployment of a compacting head in a waste compartment includes an eutectic alloy fusible link positioned within a waste compartment that breaks at or above a predetermined temperature, a spring tensioned deploy lever that is deployed based on a break of the eutectic alloy fusible link, a pivotal joint assembly that collapses based on deployment of the deploy lever, and a compacting head of a trash compactor that is deployed to compact contents of the waste compartment based on collapse of the pivotal joint assembly.

An integrated hand cleaning system includes a hand cleaning housing including dispensing spout and a sensor. An actuator is operatively connected to the housing. A cleaning substance reservoir is in fluid communication with the dispensing spout. A controller is operatively connected to the sensor and to the actuator. The controller is configured to activate the actuator based on detection of a user's hand by the sensor. A method for controlling a hand cleaning system includes receiving, with a controller, a sensor signal from a sensor in a hand cleaning housing. The method includes activating an actuator of a hand cleaning system with the controller based on the sensor signal.

Provided is a toilet exterior structure of an aircraft lavatory unit. A shroud mount in an upper end outer peripheral plate portion is provided in a lower surface of a main body plate portion. The shroud mount includes space portions extending in the width direction of the main body plate portion between partition walls provided in the main body plate portion. Where the body plate portion is placed in the upper end outer peripheral plate portion, a plurality of air communication passages communicating a space inside of the upper end outer peripheral plate portion in the width direction and a space outside of the upper end outer peripheral plate portion in the width direction are formed by the space portions. Where the main body plate portion is stepped on by a foot, the plurality of partition walls are positioned inside of a contour of the foot.

A thermostat mixing valve for a water temperature control system may comprise a mixing chamber defining a valve outlet, a first proportional solenoid valve fluidly coupled to the mixing chamber, and a second proportional solenoid valve fluidly coupled to the mixing chamber. Each of the first proportional solenoid valve and the second proportional solenoid valve may include a housing assembly defining a fluid inlet and a fluid outlet, a plunger assembly configured to translate relative to the housing assembly, and a coil assembly configured to generate a magnetic field that translates the plunger assembly.

Described are aircraft cabin arrangements (12) with at least one lavatory unit (14) with a first side wall (1402) and at least one seat unit (16) positioned adjacent the first side wall. A separate wall is not positioned between the first side wall and the at least one seat unit. The first side wall includes a recessed portion, and the at least one seat unit includes a foot support surface (1606) incorporated into the recessed portion of the first side wall.

This invention relates in general to a system for treating hard water encountered in aircraft potable water equipment; such as hot water heaters and, more particularly, to the prevention of scale deposits in aircraft lavatory and galley heated water system components by installing a unique scale reduction system. The scale reduction system generally comprised of a housing with a modular cartridge inserted therein. The cartridge is porous and contains a chemical composition within its inner cavity, and this chemical composition is mixed with untreated inlet fluid flow so that the outlet flow is of a sufficiently diluted concentration. Various chemical compositions may be utilized to counteract any number of conditions that affect potable water equipment and, in one embodiment, a water softening agent is utilized to combat scale build-up in aircraft plumbing.
