First Claim
1. A dispensing system (1) for use in conjunction with a washing machine, dishwasher, or other water-conveying domestic appliance (2) having a water conveying line that conveys water into a treatment compartment (6) in which items are to be washed, the dispensing system comprising:
- at least one reservoir (3a, 3b, 3c) for storing a plurality of dispensing portions of at least one flowable preparation (4a, 4b, 4c);
at least one dispenser (5a, 5b, 5c)which is couplable with the at least one reservoir (3a, 3b, 3c),which is configured to be positioned outside the treatment compartment (6), andwhich does not comprise any connection to the water-conveying line;
at least one sensor, which at least detects the presence of water in the water-conveying domestic appliance,at least one apparatus, selected from the group consisting of a pump and a vibratory atomizer, for delivering or releasing preparation from the reservoir or dispenser,at least one control unit, which cooperates with the sensor and the pump or vibratory atomizer such that, if a defined sensor signal is present, which represents one or both of the presence of water and the operation of the water-conveying domestic appliance, at least one preparation is delivered from the reservoir or dispenser by means of the pump or vibratory atomizer, andat least one fluid line (7, 7a, 7b, 7c), which connects the reservoir (3a, 3b, 3c) or the dispenser (5a, 5b, 5c) with the treatment compartment (6) of the water-conveying domestic appliance (2), such that the preparation (4a, 4b, 4c) may be supplied from the dispenser (5a, 5b, 5c) positioned outside the treatment compartment (6) of the water-conveying domestic appliance (2) via an orifice (8, 8a, 8b, 8c, 9, 10, 10a, 10b, 10c) of the water-conveying domestic appliance (2) connected with the treatment compartment (6) into the treatment compartment (6) of the water-conveying domestic appliance (2).
