Detergent delivery device

摘要

The invention relates to a multi-dosing detergent delivery device. In embodiments of the present invention, the multi-dosing detergent delivery device comprises: a housing comprising a base and a lid; a refill holder and shaft located within the housing and arranged, in use, for receiving thereon a cartridge having a plurality X of chambers each accommodating a detergent composition; a directing means formed in the lid of said device to direct, in use, wash liquor collected on said lid selectively into a chamber of the cartridge to contact the detergent composition therein; an outlet formed in a base region of said housing to allow, in use, detergent loaded wash liquor to exit the device; and indexing means located within the shaft of the device for causing, in use, automatic movement of said cartridge relative to said housing during and subsequent to a wash cycle so as to cause a neighboring chamber to be in an exposed, ready to be used, position prior to a next washing cycle, said indexing means comprising: a thermally reactive element, a resilient biasing means, a gearing mechanism and a clutch element for selectively decoupling torque forces generated by expansion of said thermally reactive element from said shaft.

1. A multi-dosing detergent delivery device, comprising:
a housing comprising a base and a lid; a refill holder and shaft located within the housing and arranged, in use, for receiving thereon a cartridge having a plurality X of chambers each accommodating a detergent composition; a directing means formed in the lid of said device is adapted to direct, in use, wash liquor collected on said lid selectively into a chamber of the cartridge to contact the detergent composition therein; an outlet formed in a base region of said housing which is adapted to allow, in use, detergent loaded wash liquor to exit the device; and indexing means located within the shaft of the device adapted for causing, in use, automatic movement of said cartridge relative to said housing during and subsequent to a wash cycle so as to cause a neighbouring chamber to be in an exposed, ready to be used, position prior to a next washing cycle, said indexing means comprising: a thermally reactive element, a resilient biasing means, a gearing mechanism and a clutch element adapted for selectively decoupling forces generated by expansion of said thermally reactive element from said shaft.
