Description
- The present invention concerns improvements in or relating to toilets and to ventilation of a room or other enclosed space containing a toilet. In particular, though not exclusively, the present invention relates to a toilet having an odour extraction apparatus.
- There is a common desire to remove unpleasant odoriferous gases which arise during use of a toilet. There is also a requirement to provide ventilation to WCs and bathrooms, especially internal WCs or bathrooms where there is no external wall or window. Proposed solutions include using a modified toilet bowl or seat having an aperture or bore in communication with a duct and an extractor fan to provide improved ventilation of the toilet bowl.
- It has been found that such prior art has a disadvantage of being inefficient and/or liable to collect water during the flushing process.
- There is, therefore, a need for an improved toilet having an odour extraction apparatus.
- WO99/35349 by the present applicant discloses an odour extraction apparatus for use within a toilet bowl, the apparatus comprising: a chamber adapted for communication with an evacuation means and an outlet from the evacuation means. The odour extraction apparatus is adapted so as to be fitted to a rear portion of the toilet bowl such that in use the evacuation means acts to remove odours from the toilet bowl via the chamber. However, there is a desire to further improve this apparatus.
- It is, therefore, an object of the present invention to obviate or at least mitigate one or more problems in the prior art.
- According to a first aspect of the present invention there is provided a toilet comprising:
-
- a toilet bowl; and
- an odour extraction apparatus,
the toilet bowl having a flush water inlet and an odour extraction outlet communicable with the odour extraction apparatus, and wherein at least a portion of the odour extraction outlet is located higher up the toilet bowl than the flush water inlet.

- The height of the odour extraction outlet and the flush water inlet is taken to be the height above the base of the toilet bowl.
- Preferably, the odour extraction outlet includes an extraction passage extending from within a flush channel of the toilet bowl. The flush water inlet communicates with the flush channel.
- Preferably the extraction passage is formed within a top rim of the toilet bowl.
- Preferably, the passage enters the toilet bowl at an acute angle to the flush rim.
- Preferably, the odour extraction outlet channel and odour extraction apparatus provide a substantially unrestricted flow path such that, in use, gases lose an minimal amount of energy when evacuated therethrough.
- Preferably, there is provided a substantially straight flow path between the odour extraction outlet and the odour extraction apparatus.
- Preferably, the odour extraction apparatus further comprises an evacuation chamber, and wherein there is provided a substantially straight flow path between an outlet from the extraction apparatus and an inlet to the evacuation chamber, such that, in use, gases lose a minimal amount of energy when evacuated therethrough.
- Preferably, the evacuation chamber is attached to a cistern.
- In one embodiment the evacuation chamber may vent directly to an outside region via an external wall.
- In an alternative embodiment the evacuation chamber may vent to an external vent pipe, the vent pipe being coupled to a plurality of toilets. This latter arrangement is particularly advantageous, e.g. in communal buildings such as hotels, offices or the like.
- Preferably, the odour extraction outlet is disposed towards a rear portion of the toilet bowl.
- Preferably, there are provided a plurality of odour extraction outlets and each odour extraction outlet has a corresponding odour extraction apparatus. The plurality of odour extraction apparatus are connected in parallel to the toilet bowl.
- Preferably, each odour extraction apparatus comprises at least one extractor fan.
- Preferably, each extractor fan vents odours directly to an outside region via an external wall.
- According to a second aspect of the present invention there is provided a toilet bowl having a flush water inlet and an odour extraction outlet, and wherein at least a portion of the odour extraction outlet is located higher up the toilet bowl than the flush water inlet.
- Preferably the entire odour extraction outlet is located higher up the toilet bowl than the flush water inlet.
- Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:—
-
FIG. 1 is a schematic side view of a first embodiment of a toilet; -
FIG. 2 a is a cross-sectional side view of the toilet ofFIG. 1 ; -
FIG. 2 b is a schematic plan view of the toilet ofFIG. 2 a; -
FIG. 2 c is a cross-sectional view along line A-A shown inFIG. 2 b; -
FIG. 2 d is a cross-sectional view along the line B-B shown inFIG. 2 b; -
FIG. 3 is a rear view of a toilet bowl of the toilet ofFIG. 1 ; and -
FIG. 4 is a schematic side view of a second embodiment of a toilet. - As illustrated in
FIGS. 1 and 2 a-2 d, atoilet 10 comprises atoilet bowl 12, and anodour extraction apparatus 13 in the form of anextraction fan 14 and ducting 16 connected to the toilet bowl via anodour extraction outlet 20. Thetoilet bowl 12 has aflush water inlet 18 and twoodour extraction outlets 20. Theodour extraction outlets 20 are housed in atop rim 22 of thetoilet bowl 12. Thetoilet bowl 12 is a one-piece moulded unit. However, it should be appreciated that thetoilet bowl 12 could be manufactured from any suitable number of pieces, moulded or not. - As best illustrated in
FIG. 2 b, eachodour extraction outlet 20 is coupled to anodour extraction apparatus 13 and is positioned such that at least a portion of eachoutlet 20 is located higher on thetoilet bowl 12 than theflush water inlet 18. In other words, at least a portion of eachoutlet 20 is higher from the base of thetoilet bowl 12 than theflush water inlet 18, at the point where each of theoutlets 20 andinlet 18 open into thebowl 12. This height difference is illustrated inFIG. 1 , where the height A of theoutlet 20 is greater than the height B. In fact, it is preferable that theentire outlet 20 is located higher on thetoilet bowl 12 than theinlet 18. Theodour extraction apparatus 13 are coupled to thetoilet bowl 12 in parallel. - The
toilet 10 may also comprise acistern 24 which is coupled to theflush inlet 18 of thetoilet bowl 12 in a conventional manner, so that thetoilet bowl 12 may be flushed and the contents thereof removed via awaste outlet 26. - The
apparatus 10 further includes a switch (not shown) which is activated by a user so as to activate theextractor fans 14. Eachextractor fan 14 has a timer which deactivates thefan 14 after a predetermined amount of time has elapsed after thefans 14 have been activated. Alternatively, theextractor fans 14 may be activated by the act of flushing or even entry of an individual into a closed space containing thetoilet 10. - Now referring specifically to
FIGS. 2 a to 2 d, it can be seen that theflush water inlet 18 is located in a central rear position of thetoilet bowl 12. Thetoilet bowl 12 includes aflush channel 30 located within therim 22, which directs water from theinlet 18 around thebowl 12. As well as being positioned such that at least a portion of eachoutlet 20 is higher than theflush inlet 18, the twooutlets 20 are also laterally spaced from one another and positioned in a rear portion of thetoilet bowl 12. - The
outlets 20 includeextraction passages 28 which connect theoutlets 20 and thebowl 12. Theextraction passages 28 open into thebowl 12 at a greater height above the base of thetoilet bowl 12 than either theflush inlet 18 orflush channel 30. Theextraction passages 28 extend downwards from therim 22 and enter thetoilet bowl 12 at an acute angle to theflush channel 30. By positioning thepassages 28 in therim 22 above theflush channel 30, thepassages 28 capture any rising gases generated in thetoilet bowl 12, and direct the gases to theoutlets 20. -
FIG. 2 b illustrates how the twoextractor fans 14 are coupled to theirrespective outlets 20 in thetoilet bowl 12. Downstream, thefans 14 are connected viaextraction ducts 16 to anevacuation chamber 50, or alternatively a vent pipe (not shown). Theevacuation chamber 50 may vent directly to an outside region via an external wall (not shown). Alternatively, theevacuation chamber 50 may vent to an external vent pipe (not shown), the vent pipe being coupled to a plurality of toilets. - The
toilet 10 is arranged such that eachodour extraction apparatus 13 is substantially co-axial with itsrespective outlet 20. In other words, theoutlet 20,fan 14 andextraction duct 16 are co-axial. As a result, thetoilet 10 ensures that extracted gases have a substantially unrestricted flow-path out of the toilet. Consequently, theodour extraction apparatus 13 can extract gases more efficiently as thefans 14 do not have to work excessively to move the gases around restrictive passages in the apparatus. - To further assist in the efficient extraction of the gases, the
extraction outlet 20 tapers outwardly in the direction of gas flow away from the toilet bowl, such that a remote end of theoutlet 20 which attaches to the fan has a greater diameter than an opposite end of theoutlet 20 at the toilet bowl. In addition, thefan 14 and a first end of theextraction duct 16 attached thereto have the same diameter as the remote end of theoutlet 20. A second end of theextraction duct 16 remote from thefan 14 tapers to a narrower diameter than the first end in order that theextraction duct 16 can be attached to a typical waste pipe. As an example of these relative diameters, the remote end of the outlet, the fan and first end of the extraction duct have a diameter of 90 mm whilst the second end of the extraction duct has a diameter of 40 mm. - In a preferred embodiment, the
fans 14 are 12V fans which are powered from the standard wiring circuit of the building or transportation means in which thetoilet 10 is installed. The diameter of the fan (i.e. the fan blades) may be chosen such that thetoilet 10 may be used as a ventilation unit for bathrooms, public toilets and the like. This eliminates the need for additional fans to remove moisture or the like from the room. - In one embodiment, the fans are variable speed fans and when the toilet is not being used, the fans may run at a high speed to allow air to be extracted. However, when the toilet lid is raised or when a person sits on the seat of the
bowl 12, a switch will be activated to reduce the speed of the fans allowing a more gentle flow of air to be drawn through the toilet bowl. - The toilet of the present invention may be provided in a building structure, e.g. a house; a communal building, e.g. a block of flats, offices, a hotel or the like; a static caravan or the like; or in a transportation means, e.g. an aeroplane, train, bus, motor home, caravan or the like.
- In certain applications, e.g. if the
toilet 10 is located in an internal room (i.e. a room with no external wall to the outside), then a flexible hose or the like is used to couple theextractor ducts 16 to an internal vent pipe associated with a main waste outlet be means of a T-junction. The internal vent pipe may receive the output of a plurality ofsuch toilets 10. Typically, the internal vent pipe extends along or up a building in which a toilet is located and provides a centralised vent to an outside region. This may be the case, for example, in commercial premises such as hotels or offices. - In use, the
toilet 10 is used for evacuating odoriferous gases which arise during use of a toilet. This is achieved by a user activating a switch (not shown), so as to activate theextraction fans 14 which draw air from thetoilet bowl 12 and out through theextraction ducts 16. When the toilet is flushed there is less likelihood of water being drawn into theextraction apparatus 13 or any part thereof because at least a portion of theodour extraction outlets 20 are above theflush water inlet 18. Furthermore, positioning the extraction outlets as high as possible in the toilet bowl ensures that any gases rising in the bowl are caught and extracted through the extraction outlets. - Although the
toilet 10 has been shown and described above having pairs ofodour extraction outlets 20 and associatedodour extraction apparatus 13, it should be appreciated that thetoilet 10 may alternatively comprise asingle outlet 20 andodour extraction apparatus 13. The singleodour extraction apparatus 13 would comprise afan 14 andextraction duct 16 and be connected to thesingle outlet 20. - Additionally, whilst the illustrated preferred embodiment of the invention shows the
odour extraction apparatus 13 andodour extraction outlets 20 as co-axial about a generally horizontal axis, it should be appreciated that this is not the only arrangement possible. As an alternative, theodour extraction apparatus 13 andodour extraction outlets 20 can be co-axial about a generally vertical axis, as shown inFIG. 4 . This allows theextraction apparatus 13 andcistern 24 to be close coupled within an existing flush-fit cistern housing 40 if desired. - Furthermore, the
extractor fans 14 may be actuated by operation of a light switch used to illuminate the room in which thetoilet 10 is located. Alternatively, theextractor fans 14 may be operated by opening the door of the room in which thetoilet 10 is located. - The toilet bowl may further comprise a toilet seat (not shown) which houses the
outlets 20. Whether or not theoutlets 20 are housed in the seat, the seat may have an elastomeric strip disposed peripherally on an underside thereof. The strip provides a seal between the seat and thetoilet bowl 12, at least when a person is sitting on the seat. This seal helps to contain odours and ensures that the air flow comes from a front area of the toilet. - The toilet may comprise one or more odour extraction outlets and respective odour extraction apparatus.
-
Extractor fans 14 may be used which have non-return vanes attached to the fan. In this way, if a fan stops working, it will not allow air to flow back into the toilet. Alternatively, a non-return valve can be provided in the ductwork downstream of the fans (i.e. on the other side of the fans from the toilet bowl) to prevent any external air entering the apparatus. Furthermore, this arrangement allows for a single speed fan to be used, such that if the apparatus is to be used in a dual role, i.e. to also ventilate a room, one fan can be stopped when a person is to use the toilet, without the air being forced back into thetoilet bowl 12. - An additional extractor fan may be provided between the
ducting 16 and vent pipe to enhance the airflow through theextraction apparatus 13. - These and other modifications and improvements may be incorporated without departing from the scope of the present invention.
