Modular lavatory wall with quiet flush plenum

Abstract

Embodiments of the present disclosure relate generally to passenger transport vehicle-based lavatories. Specifically, this disclosure provides improved lavatory walls and configurations for venting and noise reduction. The walls may include a plenum forming a chamber with one or more openings, in order to help remove odors from the laboratory environment via venting.

What is claimed is: 
     
         1 . A venting system for a closed environment, comprising:
 a plenum comprising an interior chamber;   a plurality of openings formed along an outer surface of the plenum; and   a valve connection area on the plenum for fluidly connecting the plenum to a vacuum source.   
     
     
         2 . The system of  claim 1 , wherein the plenum is installed along a wall in an aircraft lavatory. 
     
     
         3 . The system of  claim 1 , wherein the plenum forms an aircraft lavatory wall. 
     
     
         4 . The system of  claim 1 , wherein the plenum comprises a flattened, curved tube. 
     
     
         5 . The system of  claim 1 , wherein the plurality of openings are generally uniformly spaced across the plenum. 
     
     
         6 . The system of  claim 1 , further comprising a valve leading to the vacuum source, wherein opening of the valve applies vacuum to the interior chamber of the plenum and pulls air from the closed environment into the plenum. 
     
     
         7 . The system of  claim 6 , wherein the air pulled from the closed environment into the plenum is directed to a transient holding tank. 
     
     
         8 . The system of  claim 6 , wherein the air pulled from the closed environment into the plenum is directed to a vacuum waste tank. 
     
     
         9 . The system of  claim 1 , wherein the plenum is formed of a foam core material. 
     
     
         10 . The system of  claim 1 , wherein the plenum is shared by two spaces to be vented. 
     
     
         11 . The system of  claim 10 , wherein the plenum is shared by first and second lavatory spaces. 
     
     
         12 . The system of  claim 1 , wherein the plenum further comprises a wall formed with an internal space on an outer portion of the wall, wherein the internal space is designed to house one or more components. 
     
     
         13 . The system of  claim 12 , wherein the one of more components comprise a video screen, a cabinet, or a non-load bearing façade. 
     
     
         14 . A method of venting an environment, comprising:
 providing a plenum comprising a plurality of openings for receiving airflow, the plenum further comprising a valve connection area that cooperates with a valve leading to a vacuum source;   opening the valve in order to apply vacuum to the plenum.
