Abstract

A device for ventilating the bowl of a water closet comprises an extractor unit e.g. a fan (B), coupled via ducting (6) to an aperture in the flush pipe and to the flush pipe (F). <IMAGE>

Description

PAN FAN SPECIFICATION This invention relates to a toilet bad smell extraction system.
As toilets are receptacles into which human excrement is discharged, in almost all cases, there is an accompanying bad odour.
The traditional way of coping with the problem of bad odours in rooms that contain toilets is by means of wall or window ventilators, quite a considerable distance from the source of the odours.
There are several other inventions that extract stale air from a toilet bowl, however, they are all relatively complex, expensive and involve a great deal of extra attachment to the cistern and or toilet seat.
The principle of most water flushed toilet W.C. pans is that water is sucked by syphonic action from a cistern down pipe and distributed around the toilet W.C. pan via a chamber into a flushing rim at the top inside of the toilet W.C. pan itself.
Incorporation of the PAN FAN attached directly onto a toilet system, either a close coupled system or a separated higher level system will almost totally eliminate bad smells at the source.
DESCRIPTION: The PAN FAN invention sucks air from the flushing rim (incoming water passage) area inside of the toilet pan and directs the air into the bottom of the PAN FAN box area up into the P TRAP" (anti-splash), down through an electrically driven axial fan (which provides the suction) in a tube and out through an anti-backdraft shutter into the top of the soil pipe or any other ventilation pipe taking the stale air outside of the building. This aformentioned description applies to "close-coupled type toilet systems where the toilet bowl or pan is attached directly to a cistern. The PAN FAN invention can also be attached to high level type systems which obviates the need for the PAN FAN box and "P - TRAP" as shown in FIG 2. The two applications utilise the same principles and technology.
Specific embodiments of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 shows in perspective the PAN FAN box installed into a close coupled W.C. toilet pan and cistern. The box is coupled between the cistern and pan by extending the two wing nuts used normally to attach these two units.
Alternatively it can be manufactured not as an attachment but integrated within the cistern itself incorporating the same principles and technology.
Figure 2 shows in perspective the PAN FAN without the box, installed into a high level cistern and W.C. pan configuration.
Figure 3 shows the complete PAN FAN attachment, separated from both the pan and the cistern.
In Figure 1 air is sucked out of the inside toilet pan area via the water rims, into the boxed chamber, up and down the "P - Trap" at the rear of the cistern, via a flexi-hose or pipe, through the axial fan, and out through the anti-backdraft shutter into a soil pipe or ventilator pipe to the outside of a building.
When water descends from the cistern through the PAN FAN box and into the toilet bowl, the anti splash "P TRAP" system prevents water flowing towards the fan. The anti backdraft shutter prevents unpleasant odours from the soil pipe or air drafts from outside returning into the system when the fan is turned off.
In Figure 2 the air is sucked directly from the rim inside of the toilet pan, up through the cistern connecting pipe, then off into a pipe that leaves at an inclining angle before turning downwards through the axial fan and antibackdraft shutter and into the soil or ventilator pipe.
The principle of the PAN FAN invention is the removal of the stale air directly from the toilet W.C. pan itself, utilising the incoming water passages as an outgoing air passage, whether via the PAN FAN box and "P TRAP" attached to or inside of the cistern or directly from the piping and through the PAN FAN axial fan unit attached to a higher level separated cistern type of unit.
The electrical switching on and off of the PAN FAN can either be manual or automatic by linkage to the toilet seat or even an electronic eye type of switching, P.I.R. (passive infra red).

CLAIMS The PAN FAN invention sucks air from the flushing rim (incoming water passage) area inside of the toilet pan and directs the air into the bottom of the PAN FAN box area up into the "P TRAP" (anti-splash), down through an electrically driven axial fan (which provides the suction) in a tube and out through an anti-backdraft shutter into the top of the soil pipe or any other ventilation pipe taking the stale air outside of the building. This aformentioned description applies to Rgclose-coupled type toilet systems where the toilet bowl or pan is attached directly to a cistern. The PAN FAN invention can also be attached to high level type systems which obviates the need for the PAN FAN box and P - TRAP" as shown in FIG 2. The two applications utilise the same principles and technology.
1. The PAN FAN invention effectively removes bad smells from a toilet W.C pan by sucking air out of the toilet pan (via the incoming water passages) through the "PAN FAN" unit and "P - TRAP", down through an axial fan and out through an anti backdraft shutter into a soil pipe or other external ventilating pipe.
2. The PAN FAN greatly reduces and almost totally eliminates smells normally associated with toilet pan odours from toilet rooms.
2. The PAN FAN greatly reduces and almost totally eliminates smells normally associated with toilet pan odours from toilet rooms.

The PAN FAN invention effectively removes bad smells from a toilet W.C pan by sucking air out of the toilet pan (via the incoming water passages) through the "PAN FAN" unit and "P - TRAP", down through an axial fan and out through an anti backdraft shutter into a soil pipe or other external ventilating pipe.
