Definitions

  • the present patent application relates to a system used to feed WC flushing tanks with recycled water.
  • the specific purpose of the present invention is to devise an effective versatile system that can be installed in any room-bathroom, including pre-existing ones.
  • the system of the invention is finally able to recycle the water that has been previously used in the sink, other sanitary fittings (such as the bathtub) and also in household appliances installed in the same room-bathroom (such as a washing machine) and use it in the WC flushing tank.
  • Another purpose of the invention is to give the system a simple inexpensive structure, composed of a few “dedicated” parts designed to operate in coordination with the sanitary fittings and the branch line of the domestic water network installed in the room-bathroom in a simple, practical and inexpensive way.
  • the idea on which the present invention is based is to provide a recovery tank, preferably positioned under the sink, designed to receive the water previously used in the sink, in other sanitary fittings and in the washing machine installed in the same room.
  • the recovery tank must be connected by means of an ordinary supply pipe, with the branch of the domestic water network that feeds the traditional WC flushing tank.
  • the system of the invention will automatically interrupt the supply of “clean” water brought by the said branch of the domestic water network that is normally connected to the WC flushing tank.
  • the WC flushing tank is reloaded—until it is possible—with the water that has been already used in the sanitary fittings or washing machine, without having to get water from the domestic network, thus considerably limiting the use of water resources.
  • system of the invention is also capable to automatically remedy the possible absence of water inside the recovery tank.
  • the system will fill the WC flushing tank with the “clear” water normally provided by the domestic water network, at least until the recovery tank is not filled again.
  • FIG. 1 is a diagrammatic drawing of the system of the invention installed in a typical room-bathroom.
  • the system of the invention comprises a recovery tank ( 1 ) that, in the constructive embodiment shown in FIG. 1 , is designed to receive the water already used in the sink (L) and in the washing machine (LB).
  • the water coming from the sink (L) and the washing machine (LB) is poured into the tank ( 1 ) by means of corresponding delivery pipes ( 2 , 3 ), while the possible water excess inside the tank ( 1 ) is eliminated by means of an “overflow” valve provided on top of the tank and connected to the sewage by means of an outflow pipe ( 4 ).
  • the tank ( 1 ) is also provided with a pump ( 5 ) that draws approximately at the height of the bottom wall and with a float-switch ( 6 ) designed to detect the level of the water contained in the tank ( 1 ).
  • the pump ( 5 ) is designed to feed, with the water contained in the tank ( 1 ), a pipe ( 7 ) that is inserted, at the opposite end, into a branch ( 8 ) of the domestic water network.
  • branch ( 8 ) that is inserted into the flushing tank (C) of the WC (W), with the interposition of a traditional inlet valve ( 9 a ) that is traditionally controlled by a float ( 9 ).
  • Additional parts of the system of the invention are a feed check valve ( 7 a ) mounted along the pipe ( 7 ) situated between the recovery tank ( 1 ) and the branch ( 8 ) of the domestic water network, a flow sensor ( 11 ) mounted in the section of the branch comprised between the insertion point (P) of the pipe ( 7 ) and the flushing tank (C), and a normally open electrovalve mounted along the branch ( 8 ) upstream the insertion point (P) of the pipe ( 7 ).
  • the operation cycle of the system of the invention starts every time the water contained in the flushing tank (C) is flushed towards the WC (W).
  • the emptying of the flushing tank (C) is detected by the flow sensor ( 11 ) when the sensor ( 11 ) detects that “clear” water has resumed flowing along the branch ( 8 ) following to the opening of the valve ( 9 a ).
  • This information acquired by the flow sensor ( 11 ) is transmitted to the control unit ( 10 ), which is responsible for the entire operation of the system of the invention.
  • control unit ( 10 ) also receives from the float-switch ( 6 ) of the recovery tank ( 1 ) the information about the possible presence of water inside the recovery tank ( 1 ) and, in case of the presence of water, it immediately activates the operation of the pump ( 5 ) and the closing of the electrovalve ( 8 a ).
  • the control unit ( 10 ) sends the pump ( 5 ) a stop control as soon as the recycled water coming from the tank ( 1 ) has completed the filling of the flushing tank (C).
  • the information about the said filling is transmitted to the control unit ( 10 ) by the flow sensor ( 11 ), which immediately detects the stop of the recycled water flow inside the pipe ( 7 ) that is produced as soon as the float ( 9 ) of the flushing tank (C) has closed the inlet valve ( 9 a ) once the filling has been completed.
  • the system of the invention is able to fill the flushing tank (C) also in the case in which the recovery tank ( 1 ) is empty.
  • control unit ( 10 ) omits to actuate the pump ( 5 ) and to close the electrovalve ( 8 a ) provided along the branch ( 8 ) of the domestic water network.
  • a similar valve ( 7 a ) prevents the “clear” water brought by the branch ( 8 ) from pouring also in the recovery tank ( 1 ) in addition to the flushing tank (C).
  • the float-switch ( 6 ) will send the information to the control unit ( 10 ), which will use it in case of a new emptying of the flushing tank (C), activating a new filling cycle of the flushing tank (C) with recycled water.
  • the system of the invention is also provided with an additional feature for the good filling of the flushing tank (C) of the WC (W).
  • This feature is actuated in the situation in which the recovery tank ( 1 ) contains recycled water, but not in sufficient quantity to guarantee the complete filling of the flushing tank (C).
  • the initial operation of the system of the invention is normal, meaning that, following to the emptying of the flushing tank (C), the control unit ( 10 ) closes the electrovalve ( 8 a ) and simultaneously actuates the pump ( 5 ) of the tank ( 1 ).
  • the control unit ( 10 ) interrupts the operation of the pump ( 5 ) and reopens the electrovalve ( 8 a ) mounted on the branch ( 8 ) of the water network.
  • control unit ( 10 ) is the simple consequence of the information received from the float-switch ( 6 ) about the draining of the recycled water in the tank ( 1 ); it being provided that, upon receiving a similar piece of information, the control unit ( 10 ) reacts stopping the pump ( 5 ) and opening the electrovalve ( 8 a ).
