Abstract

The claim is to have possibly solved a minor problem that needs solving that has not been solved over the decades either by Inventors like me or the Toilet Industry which has had the opportunity and time but hasn't, and has not even shown a responsible interest in my contacts to them.

The claim shows three very distinct Modifications to the Castings of standard Toilets with Unique features such as a well placed exit hole which would standardize the placement of the exhaust tube in the wall giving New home Builders some confidence to put in the cheap pipes.

The Claim provides for the inexpensive Modification of most if not all Toilet types giving Marketers a range of products to offer installers where Vacuum Manufacturers could also anticipate enough volume to adapt some of their small inexpensive hand-held's to the exhaust pipe.

The claim is somewhat similar to some previous Patents such as one with a suction chamber cast above the flush water channel not in front but none found draw air down through the water and out the uh bottom which is not a obvious way to remove Air from the top of a Tank.

Description

SUMMARY

The Invention is a method of removing unwanted air from a Toilet Bowl.

DRAWING VIEWS

There are 9 Drawings provided where #[0002] 1 and #2 are of a Bowl and Tank and #3 and #4 are of a Tank only and #5 ,6 and 7 are bathroom ceiling fans and #8 and 9 are of a 1½ inch butterfly valve used to shut off vacuum air flow

DETAILS OF DRAWINGS

FIG. 1 is looking down on a standard uni Bodied Toilet showing the addition of a Channel inside the Ceramics that moves air from the Bowl to the Tank. [0003]
FIG. 2 shows a [0004] Suction Chamber 1, in front of the flush water channel 5 where Air is sucked through the restriction passage 2 into the outlet chamber 3.
FIG. 3 shows an older style Toilet Tank where the outflow system is just a hole in the ceramic bottom of the Tank with a Air suction Tube sealed into it [0005]
FIG. 4 shows the front view of a Tank with the [0006] Air suction tube 4 actually Cast into the side front or back of the Tank similar to some tank overflow Tubes 5.
FIG. 5 shows a Modified Bathroom fan where an [0007] additional suction Chamber 1 is created by using a second fan Blade 7 which exhausts at 2 and is connected to the lower fan Blade 6 turned by a single motor 5 with inlet 4 and outlet 3.
FIG. 6 shows a Bathroom fan similar to #[0008] 5 except that the upper and lower Fan Blades are on the same Disc with an indentation to help separate the chambers.
FIG. 7 shows a Bathroom fan similar to FIG. 6 except that the Fan disk has a protrusion into the Fan body to help separate upper and lower suction. [0009]
FIG. 8 shows a [0010] butterfly valve 4 with an asymmetrical pivot 3 so it stays open with an air flow in tube 5 but when air flow stops the weight 2 closes it onto magnet
FIG. 9 shows [0011] valve 4 closed and held by magnet 1 against any air suction unless manually opened whereas airflow would keep it open as in FIG. 8

Claims

1 is to have invented a unique method of removing bad air out of several toilet bowl types utilizing an outlet under the right side of the tanks which is connected by a hose and piping to an external fan placed in the ceiling or another location such as under a house or in an attic, connected to multiple toilets.

2 is to have invented an air Channel that sucks air from a Toilet Bowl over the Toilets Flush channel to an Exit at the rear of the Toilet Body or under the right center of the Tank where it is connected to an external Vacuum source

3 is to have invented a Toilet suction Chamber or channel that is Cast in front of the Flush water channel either part way or all the way around the inside.

4 is to have invented a suction Tube to remove Air from a Toilet Bowl via the Flush channel and Overflow tube down through a hole in the Tanks bottom using an Air tube that draws the air down through the water in the right of the Tank.

5 is to have invented a Suction Tube to remove Air from a Toilet Bowl via the Flush channel and overflow tube down through the tanks water by casting the Tube as part of the Tank where it exits a hole in the night bottom of the tank

6 is to have invented a Bathroom ceiling fan that has two suction chambers where the upper is connected via a pipe or tubing to a Modified Mac Vac Toilet,

7 is to have invented a Two Chamber Bathroom fan that separates the upper chamber by using a single fan disc with Blades on the top and the bottom.

8 is to have invented a 2 Chamber Bathroom fan disc with a indentation in the disc where the Fan Body can protrude and help separate the chambers

9 is to have invented a 2 chamber bathroom fan disc with a disc protrusion that matches an indentation in the Fan Body that helps separate the 2 chambers

10 is to have invented a Butterfly valve to control air flow that will stay closed in an air flow tube until manually released and then stay open with an air flow until the air flow stops whereas it closes until manually opened again.
