The present invention relates to a fully integrated equipment installed inside a toilet tank for the extraction and evacuation of odours as well as contaminated air that is usually found in a toilet, and continuously guarantees a passive water trap to block the return of odours from the sewer connected to the sanitary appliance.
Claims15
A system for use with a toilet, the system comprising:
- a fan (2) in communication with a toilet bowl (21) for evacuating contaminated air from the toilet bowl (21);
- a water trap (6a) in communication with the fan (2) for preventing odours from returning from a sewer drain pipe (19a);
- and
- a decanter (8) having an input in communication with the water trap (6a) for preventing water loss and including a transfer chamber (8a) for removal of odours, the decanter (8) having an output in communication with a waste pipe (12) and the sewer drain pipe (19a),
- wherein the water trap (6a) and the decanter (8) are partially immersed in a permanent water retention tank (5), and wherein the water trap (6a) comprises a calibrated water filling hole (11) in communication with the permanent water retention tank (5), thereby creating a passive water trap to block the return of gases into the system when the permanent water retention tank (5) is filled with water.
A system for use with a composting device, the system comprising:
- a fan (2) in communication with a composting chamber for evacuating contaminated air from the composting chamber;
- a water trap (6a) in communication with the fan (2) for preventing odours from returning from a sewer drain pipe (19a);
- and
- a decanter (8) having an input in communication with the water trap (6a) for preventing water loss and including a transfer chamber (8a) for removal of odours, the decanter (8) having an output in communication with a waste pipe (12) and the sewer drain pipe (19a),
- wherein the water trap (6a) and the decanter (8) are partially immersed in a permanent water retention tank (5), and wherein the water trap (6a) comprises a calibrated water filling hole (11) in communication with the permanent water retention tank (5), thereby creating a passive water trap to block the return of gases into the system when the permanent water retention tank (5) is filled with water.
A box for incorporation into a direct flush tankless toilet, wherein the box comprises a system comprising:
- a fan (2) in communication with a toilet bowl (21) for evacuating contaminated air from the toilet bowl (21);
- a water trap (6a) in communication with the fan (2) for preventing odours from returning from a sewer drain pipe (19a);
- and
- a decanter (8) having an input in communication with the water trap (6a) for preventing water loss and including a transfer chamber (8a) for removal of odours, the decanter (8) having an output in communication with a waste pipe (12) and the sewer drain pipe (19a),
- wherein the water trap (6a) and the decanter (8) are partially immersed in a permanent water retention tank (5), and wherein the water trap (6a) comprises a calibrated water filling hole
(11) in communication with the permanent water retention tank (5), thereby creating a passive water trap to block the return of gases into the system when the permanent water retention tank (5) is filled with water.
