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). ## Claims ### Claim 1 Modular electrical appliance for recycling greywater, connected to a greywater drainage pipe (S1) and connected to a flush pipe (D) of a tank (WC) of a toilet, of the type which comprises: a greywater reservoir (1) connected to said greywater flush pipe (S1), an independent auxiliary reservoir (7), said auxiliary reservoir (7) being connected to a sanitary water supply (S), 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), and said three-way electrovalve (4) is, by default, open towards the greywater reservoir (1). ### Claim 2 (depends on 1) Electrical appliance according to claim 1, characterized in that the auxiliary reservoir (7) is connected to the sanitary water supply (S). ### Claim 3 (depends on 2) 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). ### Claim 4 (depends on 1) Electrical appliance according to claim 1, characterized in that the greywater flush pipe (S1) is connected to the greywater reservoir (1). ### Claim 5 (depends on 4) Electrical appliance according to claim 4, characterized in that the greywater flush pipe (S1) is connected to the greywater reservoir (1) via an aerator threaded elbow (14). ### Claim 6 (depends on 4) Electrical appliance according to claim 4, characterized in that the aerator threaded elbow (14) the greywater flush pipe (S1) comprises a prefilter (5). ### Claim 7 (depends on 4) Electrical appliance according to claim 4, characterized in that the greywater reservoir (1) comprises a vent (200). ### Claim 8 (depends on 4) Electrical appliance according to claim 4, characterized in that said auxiliary reservoir (7) comprises an aerator elbow in its upper part (14′). ### Claim 9 (depends on 4) Electrical appliance according to claim 4, characterized in that it comprises a sensor (10) located in the greywater reservoir (1), said sensor (10) being capable of detecting a predetermined minimum level of a volume of greywater stored in said tank (1). ### Claim 10 (depends on 4) Electrical appliance according to claim 4, characterized in that it comprises an auxiliary sensor (10′) located in the auxiliary reservoir (7), said auxiliary sensor (10′) being capable of detecting a predetermined minimum level of a volume of water stored in said tank (7). ### Claim 11 (depends on 4) Electrical appliance according to claim 4, characterized in that it comprises an electrical box (13) connected, at least, to the hydraulic pump (3), to the electrovalves (4) and to the sensor (10). ### Claim 12 (depends on 11) Electrical appliance according to claim 11, characterized in that said electrical box (13) is further connected to the sanitary two-way electrovalve (17) and to the auxiliary sensor (10′). ### Claim 13 (depends on 4) Electrical appliance according to claim 4, characterized in that said greywater reservoir (1) comprises a UVA lamp (11). ### Claim 14 (depends on 4) Electrical appliance according to claim 4, characterized in that it comprises a protective outer housing (2). ### Claim 15 (depends on 14) Electrical appliance according to the preceding claim 14, characterized in that said protective outer housing (2) comprises a lock with a locking key. ### Claim 16 (depends on 4) Electrical appliance according to claim 4, characterized in that it comprises a structural body (6) for securing to an external structure.
