Toilet for use in recreational vehicle and boats

Abstract

A toilet utilizes a pressurized fluid source providing a flush volume of less than 1 gallon. A removable discharge passageway is sealingly coupled at a first end to the toilet waste outlet and at a second end to a floor flange, and defines a trapway for providing a water seal therebetween. In one example, the water seal includes a water column, and the discharge passageway is configured to maintain at least about 80% of the water column therein when the toilet is pivoted about 10 degrees. In another example, an upleg extends vertically upward a distance sufficient to maintain a minimum water column within the upleg necessary to maintain the water seal between the bowl and the floor flange when the toilet is pivoted about 10 degrees. In another example, a support bracket maintains the second end of the discharge passageway generally fixed relative to the first end.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Not applicable.FIELD OF THE INVENTION[0002]The present invention relates generally to toilets, and more particularly, to toilets for use in recreational vehicles and boats.BACKGROUND OF THE INVENTION[0003]Water saving toilets are generally known for use in recreational vehicles (RV's) and boats, or other movable vehicles. Indeed, a trend in toilet bowl design is one that achieves adequate flushing while minimizing the use of water. These toilets generally include a bowl, and a vapor seal disposed between the bowl and a waste holding tank. Moreover, these toilets are often mounted upon a floor of the vehicle, and as a result, the bowl and any contents therein are movable along with movement of the vehicle. It is known to utilize a movable, mechanical vapor seal to maintain the vapor seal despite movement of the vehicle. However, such movable mechanical seals are complex, costly, and / or prone to failure. Thus, there is a continuing need for...

[0004]The following presents a simplified summary of the invention in order to provide a basic understanding of some example aspects of the invention. This summary is not an extensive overview of the invention. Moreover, this summary is not intended to identify critical elements of the invention nor delineate the scope of the invention. The sole purpose of the summary is to present some concepts of the invention in simplified form as a prelude to the more detailed description that is presented later.

[0005]In accordance with one aspect of the present invention, toilet is adapted to be placed in fluid communication with a pressurized fluid source providing a flush volume of less than 1 gallon. The toilet includes a toilet body including a bowl, a rim, a rim wash disposed about the rim and in fluid communication with the pressurized fluid source, and a waste outlet. The toilet further includes a removable discharge passageway sealingly coupled at a first end to the waste outlet of the toilet bowl and at a second end to a floor flange. The discharge passageway defines a trapway for providing a water seal between the bowl and the floor flange. The discharge passageway includes an upleg portion and a downleg portion separated by a weir. The toilet further includes a water jet nozzle in fluid communication with the pressurized fluid source and including a discharge end in fluid communication with the waste outlet. The water jet nozzle is adapted to expel said pressurized fluid into said discharge passageway. The water seal includes a water column, and the discharge passageway is configured to maintain at least about 80% of the water column therein when the toilet is pivoted about 10 degrees from a normal position.

[0006]In accordance with another aspect of the present invention, a toilet is adapted to be placed in fluid communication with a pressurized fluid source providing a flush volume of less than 1 gallon. The toilet includes a toilet body including a bowl, a rim, a rim wash disposed about the rim and in fluid communication with the pressurized fluid source via a first dedicated line, and a waste outlet. The toilet further includes a removable discharge passageway sealingly coupled at a first end to the waste outlet of the toilet bowl and at a second end to a floor flange. The discharge passageway defines a trapway for provid
