Abstract

An odour removal device for a toilet, having a water cistern for flushing waste. The extraction device is powered by a low voltage fan, held in an enclosure situated outside the toilet room, which draws air from inside the cistern creating a vacuum, which then draws air 5 from the toilet bowl via the cistern overflow tube. The fan is powered by mains or solar power having a push button switch which automatically turns off after a set period of time. With multiple options in installation and powering, the simplicity of this device, ease of use, effectiveness in operation and alternate methods of installation, make this device unique in its field. It enables the bathroom or toilet room to remain smelling fresh at all times. Fig "A"

5. DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS: The toilet odour extraction device, in accordance with this invention, comprises an enclosure (5) housing a low voltage electric fan, having sufficient vacuum and volume to withdraw odours from the toilet bowl (1)utilising the toilet cistern overflow pipe (3)which is 5 part of the flushing mechanism of all modern toilets. The extraction fan, housed in the enclosure (5) is preferably an impellor type fan but can also be a propeller type fan and is powered by low voltage electric motor, preferably twelve volt DC but can be twenty-four volt DC. This fan unit is used to create the air flow by expelling the air from enclosure (5) via the outlet (8) causing a vacuum to be created inside of enclosure (5). The outlet of the fan 10 unit is sealed from the inlet of the fan unit, which is open to the interior of the enclosure (5). An alternative method of manufacture is to have the inlet of the fan fluidly coupled to the connecting pipe (6), causing pressure to be created inside enclosure (5), so to be released through outlet (8) of enclosure (5). Air flow is directed through connecting pipe (6) thereby causing negative air pressure or vacuum to transfer into cistern (2) above water level (7). 15 This causes an extraction of odorous air from the toilet bowl (1) via water overflow pipe (3) passing through extraction fan, to be exhausted through outlet (8). The extraction fan is housed in a waterproof and relatively airtight enclosure (5), being installed outside the toilet room or bathroom, preferably directly behind the toilet cistern 20 (2) with connecting pipe (6) installed under lid of said cistern (2) above the water level (7). It can also be installed remotely, either in ceiling cavity, under floor of building or away from the toilet room or bathroom in a suitable place, being in gaseous communication to the toilet cistern (2) via piping(14), said piping usually positioned on an outside wall but can be installed in the wall cavity of new toilet rooms or bathrooms, prior to wall being cladded. 25 Fan in enclosure (5) is powered by low voltage electricity preferably but not exclusively from a suitable rechargeable battery, the battery being recharged by a solar panel or panels (10) or by a mains power adapter/ transformer. Suitable discharging of fouled air can be dispersed discretely from enclosure (5) to 30 atmosphere, or ducted to a more suitable area via piping (8) attached to outlet of enclosure (5). The rechargeable battery, housed in enclosure (5) is preferably but not limited to a sealed lead acid type battery but can be of other types of storage batteries suitable to this 35 application. The battery is typically but not limited to be of a capacity between five and twelve Amp hour.

Claims

7. CLAIMS: 1. An odour extraction device for a water flushing toilet, said extraction device comprising: 5 * An enclosure/container installed externally to toilet room, having an inlet adapted for gas communication with the interior of said toilet bowl via toilet cistern. * An outlet from said enclosure vented to atmosphere or in ceiling cavity or under building. 10 * A suction means being an impellor or propeller type fan, housed in said enclosure, fan being the sole means of gas communication between said inlet and said outlet. 2. An enclosure according to claim 1, being waterproof and relatively airtight, having the means to be installed externally to toilet or bathroom: 15 * On the outside wall of toilet or bathroom, being fluidly connected through wall to toilet cistern. * In the ceiling cavity or underfloor, fluidly connected to toilet cistern via suitable piping, said piping installed on an external wall or alternatively, within the wall cavity of toilet or bathrooms. 20 3. An enclosure according to claim 1, housing the extraction fan, having the means to house the timer relay switch, the storage battery, the solar regulator, and the mains 240V to 12V DC or 24V DC transformer. 4. A toilet odour extraction device having a timer relay switch to activate said extraction fan, being brought into operation by the toilet user pressing a momentary 25 push button switch located in the toilet room or bathroom, the timer relay switch causing the extraction fan to continue to operate for a set period of time before deactivating said fan when time on timer relay switch has expired. 5. A toilet odour extraction device, having as an alternative option to claim 4, an electronic or a mechanical timer switch installed in the toilet room to activate the 30 extraction fan, activation time determined by the current user of said toilet, setting the operating time for the extraction fan as required. 6. An odour extraction device fan having the means to be powered from a storage battery, said battery being recharged by: * A solar panel. 35 9 A mains power 240V to 12V DC or 24V DC transformer. * The means to power the fan directly from 240V mains power via a 12V DC or 24V DC transformer, without the use of a battery. 7. A toilet odour extraction device as herein described as referenced to and as illustrated in the accompanying drawings.
