1. A detergent composition dispensing device adapted to be removably insertable into a washing machine, the said device comprising: a chamber to accommodate a detergent composition (or other fabric or textile treatment composition), a water detection means to detect the presence of water andor wash liquor in the machine and a pumping means or dispensing valve means to release the detergent composition from the chamber out of the device, wherein the pumping means or dispensing valve means is influenced by (responds to) an output signal from the water detection means, characterised in that the water detection means operates according to an associated algorithm (process step(s)) governing a controller means used to control the operation of the dispensing device such that water is not deemed to have been detected until water andor wash liquor has been detected as being present over a certain portion of a predetermined time interval in a wash cycle. Additionally it has been found that the presence of wet items, e.g., fabric or the presence of any extraneous water or wet items during loading of the machine cannot trigger the dispensing device.
2. A device according to claim 1, wherein the device is for use in an automatic laundry washing machine.
3. A device according to claim 1, wherein the pre-determined time interval for a laundry washing machine is between 3 to twenty minutes from the start of the washing cycle.
4. A device according to claim 3, wherein the device is triggered to dispense detergent when the device detects water in the machine for a period of from 5 to 20%% of the pre-determined time period.
5. A device according to claim 1, wherein the sensor checks for the presence of water at a frequency of from 4 to 50 Hz.
6. A device according to claim 1, wherein the algorithm incorporates a time delay after the dispensing phase.
7. A device according to claim 1, wherein the sensor tests for the conductivity of water andor wash liquor present as an indication of the presence of water.
8. A device according to claim 1, wherein the detergent is dispensed in the main wash andor the last rinse step of the washing cycle.
9. A detergent dispensing device removably insertable into a laundry machine, the device comprising a chamber to accommodate a detergent or other textile treatment composition, a light detection means to detect the presence of light in the interior of the laundry machine and a pumping means or control valve means to release the detergent or other textile treatment composition from the chamber out of the device, wherein the pumping means or control valve means is influenced by (responds to) an output signal from the light detection means, characterised in that the light detection means operates according to an associated algorithm (process step(s)) governing a controller means used to control the operation of the dispensing device such that light is not deemed to have been detected until light has been detected as being present within the laundry machine over a certain portion of a predetermined time interval in a laundry treatment cycle.
10. A device according to claim 9, wherein the device is for use in a laundry tumble dryer machine.
11. A device according to claim 9, wherein the pumping means is a micropump.
12. A device according to claim 9, wherein the pumping means is a pressurised detergent chamber closed by a control valve.
13. A device according to claim 1, wherein the chamber is removable from the device.
14. A device according to claim 9, wherein the chamber is removable from the device.
