Problems solved by technology

In regard to vacuum toilets, if the flush valve is open for too short a period of time, insufficient water may accompany the waste, which may increase the possibility of the system plugging.
A short duration flush also limits the amount of vacuum utilized in the flush and reduces the force that macerates the waste, which also increases the possibility of the system plugging.
If the flush valve is open for an extended period of time, then excessive water is utilized.
Additionally, if a second flush cycle is activated before the full level of vacuum is restored, the reduced level of vacuum may not have sufficient force to macerate the sewage, and system plugging may result.
If the flush valve is open for an extended period of time, then excessive water is utilized and it increases the possibility that malodor from the holding tank may enter the bathroom via the flush valve.

Embodiment Construction

[0021]FIGS. 1-3 show a toilet 10 (either vacuum or drop through) in accordance with the present invention having a substantially all china one-piece combination bowl and base 11, with a conventional toilet seat 12 and cover 13. In exterior appearance, the toilet 10 generally resembles conventional toilets in both size and material found in homes, businesses and the like. The toilet 10 includes an actuating mechanism 16 that activates either a flush mode or an add water mode. The actuating mechanism 16 can be any type of actuating mechanism known in the art such as, but not limited to, a foot pedal, a lever, a pushbutton, a rocker switch, etc. Further, the actuating mechanism can be located on the toilet, as shown in FIGS. 1-3, or it can be located near the toilet, for example, on a wall, a cabinet, a counter, etc. located near the toilet.

[0022]FIG. 4 shows a flush mechanism 20 in a closed state in accordance with the present invention. The flush mechanism 20 includes a frame 21 and...

Abstract

A toilet for a recreational vehicle, boat or the like is provided, which includes an electro-mechanical flush mechanism. The flush mechanism includes an actuating mechanism for activating either a flush cycle or an add water cycle. The flush mechanism further includes a flush valve, a water inlet valve, a motor, a drive mechanism and a spring. During operation of the flush mechanism, the spring biases the drive mechanism in a direction such that the flush valve rotates. A motor arm connected to the motor moves the drive mechanism in a direction such that the flush valve rotates in an opposite direction.

Description

[0001] This application claims the benefit of U.S. Provisional Patent Application No. 60 / 617,103 filed on Oct. 8, 2004.FIELD OF INVENTION [0002] The present invention relates to toilets. More particularly, the present invention relates to a toilet and flush mechanism that is suitable for a boat, recreational vehicle (RV), bus or the like. BACKGROUND OF THE INVENTION [0003] The toilet according to the present invention may either be of the gravity drop through type or of the vacuum type (such as generally shown in U.S. Pat. No. 5,621,924, the disclosure of which is hereby incorporated by reference). [0004] There currently exist in the marine and RV industries, vacuum toilets and gravity drop toilets that are foot pedal or lever operated. These are manually operated toilets where a flush valve is opened by the operator and remains open as long as the operator activates the pedal or lever. [0005] In regard to vacuum toilets, if the flush valve is open for too short a period of time, in...
