Modular electrical appliance which reuses greywater
Modular electrical appliance for recycling greywater, connected to: a drainage pipe (S 1 ) via which greywater enters into the greywater reservoir ( 1 ) thereof; a sanitary water supply (S) via which sanitary water enters into the auxiliary reservoir ( 7 ) thereof; and a flush pipe (D) which connects to the standard opening of the tank (WC) of a toilet. The electrical appliance has a built-in three-way valve ( 4 ) which opens the outlet of said greywater reservoir ( 1 ) if it contains a sufficient amount for a full flush. If not, the outlet of said auxiliary reservoir ( 7 ) is opened. A hydraulic pump ( 3 ) connected to the electrovalve ( 4 ) pumps the flush water, grey or sanitary, through the flush pipe (D).
1. A modular electrical appliance for recycling greywater, connected to a greywater drainage pipe (S 1 ) and connected to a flush pipe (D) of a tank (WC) of a toilet, the modular electrical appliance comprising:
a greywater reservoir ( 1 ) connected to said greywater flush pipe (S 1 ), wherein the greywater flush pipe is connected to one or more greywater sources selected from a group comprising of sinks, bathtubs, washing machines, and showers, said greywater flushpipe (S 1 ) being connected to the greywater reservoir ( 1 ) via a first aerator threaded elbow ( 14 ), and
an independent auxiliary reservoir ( 7 ), said auxiliary reservoir ( 7 ) being connected to a sanitary water supply (S), said auxiliary reservoir ( 7 ) comprising a second aerator elbow ( 14 ′) in its upper part, wherein no water enters the second aerator elbow ( 14 ′) and
a hydraulic pump ( 3 ) comprising a pressure switch, and said hydraulic pump ( 3 ) being connected to said flush pipe (D), and
characterized in that it further comprises a three-way electrovalve ( 4 ), this three-way electrovalve ( 4 ) comprising:
a first inlet connected to said greywater reservoir ( 1 ),
a second inlet connected to said auxiliary reservoir ( 7 ), and
an outlet connected to said hydraulic pump ( 3 ), and
in that said flush pipe (D) is connected to a standard inlet opening of sanitary water from said tank (WC), wherein the greywater reservoir ( 1 ), the independent auxiliary reservoir ( 7 ), and the hydraulic pump ( 3 ) of the modular electrical appliance are external to the tank (WC) and said three-way electrovalve ( 4 ) is, by default, open towards the greywater reservoir ( 1 ).
2. Electrical appliance according to claim 1 , characterized in that the auxiliary reservoir ( 7 ) is connected to the sanitary water supply (S).
3. Electrical appliance according to claim 2 , characterized in that the auxiliary reservoir ( 7 ) is connected to the sanitary water supply (S) via a two-way electrovalve ( 17 ).
4. Electrical appliance according to claim 1 , characterized in that the first aerator threaded elbow ( 14 ) comprises a prefilter ( 5 ).
5. Electrical appliance according to claim 1 , characterized in that the greywater reservoir comprises a vent.
6. Electrical appliance according to claim 1 , characterized in that it comprises a sensor located in the greywater reservoir, said sensor being capable of detecting a predetermined minimum level of volume of greywater stored in said tank.
7. Electrical appliance according to claim 1 , characterized in that it comprises an auxiliary sensor located in the auxiliary reservoir, said auxiliary sensor being capable of detecting a predetermined minimum level of a volume of water stored in the auxiliary reservoir.
8. Electrical appliance according to claim 1 , characterized in that it comprises an electrical box connected, at least, to the hydraulic pump, to the electrovalves and to a sensor.
9. Electrical appliance according to claim 8 , characterized in that said electrical box ( 13 ) is further connected to a sanitary two-way electrovalve ( 17 ) and to the auxiliary sensor ( 10 ′).
10. Electrical appliance according to claim 1 , characterized in that said greywater reservoir comprises a UVA lamp.
11. Electrical appliance according to claim 1 , characterized in that it comprises a protective outer housing.
12. Electrical appliance according to claim 11 , characterized in that said protective outer housing ( 2 ) comprises a lock with a locking key.
13. Electrical appliance according to claim 1 , characterized in that it comprises a structural body for securing to a wall.
