Abstract

An Air Flush Toilet, which uses a mixture of compressed air and water to facilitate the flushing action, comprises a water reservoir split into two sections and a small compressor unit which forces the water through a tube and into the toilet basin via a perforated opening in the airtight lid. To ensure that this lid is properly sealed it has a ridge running around its underside which fits into the toilet basin, and a secure catch/clip on the front of the lid which attaches the lid firmly to the toilet basin. This lid activates the flushing action when it is closed by means of a lever which is connected to the flushing arm thereby allowing the toilet to be flushed and cleaned using approximately one third of the water used in a normal flush.

Description

AIR FLUSH TOILET This invention relates to a water saving compressed air flush toilet.

An Air Flush Toilet is a normally designed/styled toilet which uses compressed air and water to facilitate the flush thereby using approximately one third of the amount of water used in a regular water flush toilet. This is done by having a toilet lid which seals the toilet pan making it airtight and a small compressor which directs a jet of air down into the pan, via a small self refilling reservoir of water. The pressure then forces all waste material out of the pan through the usual channels.

The air tight lid Fig.2 J., Fig.3 N. & Fig.4 R. through which the compressed air and water is directed has a perforated opening Fig.2 K. to allow for the jet of air & water to ensure that the bowl is properly cleaned.

When the lid is closed and sealed it initiates the flush by means of a small lever device fitted to the back of the seat Fig.2. I. and connected to the flushing arm Fig. 1 B. which starts the compressor unit Fig. 1 A. which then forces ajet of compressed air through the left side of the water reservoir Figl. D. This pushes the water in the reservoir through a tube in the toilet lid Fig.2 H. & Fig.4 P. and closes a small gate Fig. 1 C. between the right & left sections of the reservoir Fig. 1 D. & E. thus preventing any more water gaining access to the toilet.

Once the requisite amount of air has been used the compressor ceases to direct more air into the reservoir and the gate Fig. 1 C. is free to open allowing more water into the left side of the reservoir Fig. 1 D. This water goes into the lavatory pan in order to fill the bottom of the basin as is usual in a normal toilet. In order to ensure the correct amount of water is held in the right side of the water reservoir Fig. 1 E. a simple ball cock Fig. 1 F. is used.

On the lid is a small catch Fig.2 L. in order to ensure that it is properly closed and cannot be dislodged by the force of the air pressure.

Figure 1 shows a front view of the water reservoir with all inner parts displayed.

Figure 2 shows both a side view and view from below of the airtight lid.

Figure 3 shows a front view of the whole toilet unit with the lid closed.

Figure 4 shows a side view of the whole toilet unit with the lid raised.

Claims

1. An Air Flush Toilet using a mixture of air and water to complete the flush and saving up to two thirds of the amount of water used in a water flush toilet.

2. An Air Flush Toilet as claimed in Claim 1, which uses an air compressor to force a small amount of water through a perforated opening in the sealed lid to clean and flush the toilet thoroughly.

3. An Air Flush Toilet as claimed in Claims 1 & 2 with a toilet lid which fits the basin exactly to provide an airtight environment.

4. An Air Flush Toilet as claimed in Claims 1,2 & 3with a water reservoir split into two sections permitting only the required amount of water to pass through into the toilet basin. The water to be kept at the correct level by means of a regular ballcock.

5. An Air Flush Toilet as claimed in Claims 1,2,3 & 4 with a catch fitted to the front of the lid which allows the lid to be held tight thereby preventing the air pressure from dislodging it.

6. An Air Flush Toilet as claimed in all previous Claims, the action of which is triggered, by means of a lever, when the lid is closed.
