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 toilet bowl ventilation system exhausts air in and around the toilet bowl to an area adjacent to the room in which the toilet is located. The toilet bowl ventilation system includes an odor exhaust system which is configured to be installed within the interior cavity of a toilet. The odor exhaust system includes a fan positioned within a housing. The system further includes a controller that regulates power to the fan. Upon activation, the system is operable to transport air from in and around the toilet bowl, through the housing, and to an area adjacent to the room in which the toilet is located (e.g. outdoors).

A toilet seat assembly configured to enclose a toilet bowl includes a toilet seat rotatably connected to the toilet bowl, a first seal configured to seal a space between the toilet seat and a rim of the toilet seat, a rotatable hood configured to enclose the toilet seat and a second seal configured to seal a space between the hood and the toilet seat.

An air purification device for maintaining a clean smelling bathroom includes a housing, which is mountable to a tank of a toilet, and a plurality of bulbs, which is mountable to an underside of a seat of the toilet. An opening is positioned in the housing to vent the housing. A tube is attached to and extends from the housing to a bowl of the toilet. A battery, a pump, and a filter are attached to and positioned in the housing. The battery is operationally engaged to the pump and the bulbs, positioning the bulbs to selectively illuminate an area proximate to the toilet. The pump draws air from the bowl through the tube into the housing, where the filter absorbs malodorous compounds in the air to purify the air, thus maintaining a clean smell in proximity to the toilet.

A toilet seat cover assembly for automatic cleaning of a toilet seat having a toilet set cover with a top wall having a perimeter, defining a plurality of openings formed completely through the top wall, and configured to cover a toilet seat, with an outer wall extending from the top wall and with an inner wall extending from the top wall, wherein the outer and inner walls are configured to surround the toilet seat. The cover defines a seat channel sized to receive the toilet seat with outer wall spaced apart from an outer side of the toilet seat and the inner wall spaced apart from the inner side of the toilet seat. The assembly is also configured to spray over a top surface of the toilet seat that evacuated caused by pressure differential causing air to flow into the cover through the plurality of openings.

A toilet and bathroom exhaust system of the present invention provides a single system that handles both the removal of noxious air in an around the toilet and dehumidification of the air in the entire room. An intake manifold may be configured to be 1) attached to the bottom of the toilet lid; 2) attached to the top of the toilet rim; or 3) integrated into the toilet rim with the water drainage supply lines for flushing. The noxious air can be routed via an exhaust fan outside the house. The exhaust fan may also be configured to route noxious air into the trap area in the toilet. Proximity and humidity sensors may be used for further control and automation of the system.

A toilet that includes a tank configured to hold water from a water supply; a reservoir fluidly connected to the tank and configured to hold a cleaning compound comprising a chemical compound and water from the water supply; and an actuator configured to control a flush cycle of the toilet upon a first activation, the actuator including at least one nozzle fluidly connected to the reservoir and configured to discharge an amount of the cleaning compound external to the tank upon at least one of the first activation or a second activation.

The assembly is also configured to spray over a top surface of the toilet seat that evacuated caused by pressure differential causing air to flow into the cover through the plurality of openings.

A toilet seat assembly for expelling unwanted odors. The toilet seat includes a suction assembly associated with the toilet bowl. The toilet seat assembly includes a series of suction holes leading from the top surface and extending towards the bottom surface of the toilet seat a predetermined amount. The toilet seat assembly also includes a passageway underneath the series of holes which creates a path that leads towards the suction assembly exit for proper disposable of odors and fluids. The suction assembly leads unwanted odors away from the vicinity of the toilet bowl through a suction hose which permits suction from a vacuum to occur. The suction from the vacuum draws odors beginning from the series of holes found in the toilet seat assembly.
