Embodiment Construction

[0051] 1( a ) to 1( c ) show a detergent dispensing device 1 . The device 1 comprises a housing 2 in the form of a cylinder with a cover 3 and a base 4 .

[0052] Inside the housing 2 a cartridge 5 is arranged. Cartridge 5 is also based on a cylinder. The cartridge 5 has a central hub 6 and an outer periphery 7 . A plurality of limbs 8 extending from the hub 6 to the outer periphery 7 are arranged at regular intervals. The branches 8 serve to divide the center of the barrel 5 into wedge-shaped chambers 9 . Branches 8 extend as far as the cover 3, separating the chambers from each other. In the figure shown there are clearly fourteen chambers 9, it being understood that the number of chambers may be different from that shown.

[0053] The chamber is used to fill with a detergent composition (not shown).

[0054] The periphery 7 of each chamber 9 has a plurality of discharge holes 10 .

[0055] The cover 3 is rotatable relative to the remainder of the housing 2 and the ca...

Abstract

A free standing detergent dispensing device removably insertable into an automatic washing machine, the device comprising a cartridge having a plurality of unsealed chambers to accommodate a detergent composition, a directing means to direct wash liquor selectively into a chamber of the cartridge to contact the detergent composition therein, each chamber having an inlet in the form of a tortuous path to obstruct unwanted flow of wash liquor into an unselected chamber.

Description

technical field [0001] The present invention relates to a detergent dispensing device, in particular to a detergent dispensing device for dispensing said detergent into an automatic dishwasher or washing machine over a plurality of washing cycles. Background technique [0002] In automatic dishwashers, detergent in powder, tablet or gel form is usually manually filled by the user into the machine, in particular into the detergent holder, before each dishwashing operation. [0003] For powder and gel detergents, this filling process is inconvenient, the problem is that the detergent is accurately metered and the detergent may spill. Even with detergent in tablet form (where the problem of precise dosing is solved), the dishwashing detergent must still be disposed of at the start of each dishwashing cycle. This is unsuitable because dishwasher detergent compositions are usually corrosive. [0004] Various devices are known for holding unit doses of detergent composition or a...
