Abstract

The invention relates to a toilet comprising an odour extraction system. The system comprises an electrically powered air suction pump 2 which extracts odorous air from the toilet bowl through two internal side air ducts 4, via a refillable activated charcoal filter 5. The suction system releases the odours out through a pipe on the back of the unit. The system is activated by a sensor 1 placed behind the toilet bowl or, alternatively, by an ON/OFF button (3 figure 2) placed on the right hand side of the toilet seat attachment. The toilet may comprise dual flush pipe connections (1, 2 figure 8) fixed to the cistern (3 figure 8). The toilet base may comprise a cover (1 figure 4) which allows access to the hydraulic, electric, air duct connections and air pump. The cover may be secured by screws or may be locked by means of a key when the unit is used in public premises.

Description

The Odour Remover Toilet This invention relates to an electrically powered toilet which removes odours each time it is used.

In the spirit of functional refinement, the FlushAll toilet has been invented to become the next generation of toilet design and could be used in any types of premises. The essence of the design is the incorporation of an air-suction system which removes odours each time the toilet is used. This air suction system is activated either manually or by sensor, and automatically switches off after 1 minute. Both the sensor and the ON/OFF button are positioned at the back of the toilet.

There are two versions of the design that can be installed depending on the type of premises, the FlushAll ACF and FlushAll DSS. Both models can be incorporated into any size or shaped toilet facility. The design is laid out in full detail on the figures an drawings attached to this application.

The FlushAll ACF uses a refillable activated charcoal filter system that filters suctioned air, releasing it odour-free back into the room.

The invention will now be described solely by way of example and with reference to the accompanying drawings in which: Figure 1 shows the internal suction system parts and connections.

Figure 2 shows the toilet cistern and general unit buttons.

Figure 3 shows the flush connections and pipe junction points.

Figure 4 gives a top view of the unit, showing the covers 1 and 2.

Figure 5 gives a top view of the unit, showing the covers 1 and 2 screwing points.

Figure 6 gives a top view of the unit, showing an alternative lock to be fixed in the unit.

Figure 7 shows a side cut of the unit, which shows the flush and air extraction systems.

Figure 8 shows the flush system and unit body parts.

Figure 9 shows the cover 3 of the unit and the junction between the cistern and the unit base.

In figure 1, the sensor I starts the air suction pump 2 function, extracting odours through the side air suction grids 3, the connection ducts 4 and the refillable activated charcoal air filter 5. The pipe 6 is connected to the air pump and another pipe is connected to the end of the pump, giving exit to the renewed air.

Figure 2 shows the toilet cistern 1 connected to the toilet base. The flush button 2 starts the dual flush system, one each side of the bowl and the ON/OFF button 3 manually starts the air pump function.

In figure 3, the pipes 1,2 are easily connected to the dual flush system cistern though the 3,4 junction pipes.

In figure 4 the cover 1 can be easily unscrewed from the toilet base, giving access to the refillable activated charcoal filter and other system parts. The cover 2 gives easy access to the hydraulic, electric and air ducts connections and the air suction pump. The toilet seat is placed over the cover 1 and the toilet cistern is placed over the cover 2. Both parts can be easily removed if needed.

Figure 5 shows the screws 1,2 that lock the cover which gives access to the refillable activated charcoal filter compartment and the screws 3,4 that lock the cover that gives access to the air pump and other connections.

In figure 6, instead of screws, another cover model can be fit with a key 1 to lock and unlock the cover to ensure the unit is safe in case of being used in public premises.

Figure 7 shows all connections by a side cut view, starting by the air suction pump 1, extracting odours through the side air suction grids 2, the refillable activated charcoal air filter 3 and giving exit to the renewed air in pipe 4. The electrical wire 5 is connected to the air pump and a ground connection is required to this unit. Pipe 6 gives exit to waste.

Figure 8 shows the dual flush pipe connections 1,2 fixed to the cistern 3. This flush system is more efficient and gives free access to all the other connections and air pump, that are fixed in the centre of the unit. The compartment 4 is sealed by a cover that gives access to the connections and air pump. The cover for the compartment 4 can use either screws as shown in figure five or a key lock for more safety in case the unit is to be used in public premises. The toilet body parts 6,7 are firmly fixed by screws and can be made of stainless steel, aluminium or ceramic.

Figure 9 shows the third unit cover 1 which gives partial access to the connections and air pump.

The cistern and body can be split through the main connection 2 in case of any part exchange or repairs.

The FlushAll DSS is a direct suction system that pipes unfiltered suctioned air externally.

Figure 1 shows the internal suction system parts and connections.

Figure 2 shows the toilet cistern and general unit buttons.

Figure 3 shows the flush connections and pipe junction points.

In figure 1, the sensor 1 starts the air suction pump 2 function, extracting odours through the side air suction grids 3 and the connection ducts 4. The pipe 5 is connected to the air pump and another pipe is connected to the end of the pump, giving exit to the extracted air.

In figure 4 the cover 1 can be easily unscrewed from the toilet base, giving access to the system parts. The cover 2 gives easy access to the hydraulic, electric and air ducts connections and the air suction pump. The toilet seat is placed over the cover 1 and the toilet cistern is placed over the cover 2. Both parts can be easily removed if needed.

Figure 5 shows the screws 1,2 that lock the cover which gives access to the pipe connections compartment and the screws 3,4 that lock the cover which gives access to the air pump and other connections.

In figure 6, instead of screws, another cover model can be fit with a key to lock and unlock the cover to ensure the unit is safe in case of being used in public premises.

Figure 7 shows all connections by a side cut view, starting by the air suction pump 1, extracting odours through the side air suction grids 2, through the ducts 3 and giving exit to the renewed air in pipe 4. The electrical wire 5 is connected to the air pump and a ground connection is required to this unit. Pipe 6 gives exit to waste.
