A self-foaming liquid soap as a high efficiency absorbing substance is used from contaminations produced during evacuations. A water tank is comprised of two compartments: one is for flashing water that could be a regular gravity tank, or a pressure assisted flash water, and a separate compartment is for a self-foaming liquid soap. A toilet bowl is designed with two rims: one is for a flashing water and another one for a soap foam. A soap foam is applied into a bowl walls and on a water surface on a bowl bottom for protection from evacuations and reflections into a user. Analysis of a liquid flow in a toilet bowl made possible to utilize a theory of surface waves in a bowl exit outlet designed in the form of a converging-expanding channel with a high velocity liquid flow through the toilet bowl without disturbances and atomizing effects and providing a maximum efficiency detergency of bowl walls. | InventorsAssigneeApplicationNo. 11361151 filed on 02/24/2006US Classes:4/300FLUSH CLOSETField of Search4/300, FLUSH CLOSET4/300.3, With splash guard or water baffle4/420BowlExaminersPrimary: Phillips, Charles E.US Patent References3383710, 3585649, 3843976, 4571752, Sanitary device systemIssued on: 02/25/1986 Inventor: Bick5429279, Mixing chamber for mixing together a gaseous and a liquid constituent Issued on: 07/04/1995 Inventor: Van Der Heijden5443569, Foam dispensing pump container Issued on: 08/22/1995 Inventor: Uehira, et al.5813576, Container with a pump that mixes liquid and air to discharge bubbles Issued on: 09/29/1998 Inventor: Iizuka, et al.5813785, Device for the packaging, dispensing and application of a gel or foam Issued on: 09/29/1998 Inventor: Baudin, et al.5983413, High performance flush toilet Issued on: 11/16/1999 Inventor: Hayashi, et al.6427875, Foam dispensing device Issued on: 08/06/2002 Inventor: Hoang, et al.6818204, Stable foam for use in disposable wipe Issued on: 11/16/2004 Inventor: Lapidus6986172Flush toilet Issued on: 01/17/2006 Inventor: Hidetaka, et al.
