A low-foaming composition for cleaning a ware-washing machine comprises water, an alkoxylate, an acid (preferably citric acid), and preferably a phase separation promoter (for example a polyethylene glycol or an ionic salt). The composition is in two separate layers under ambient conditions.

Composition and method

The invention concerns detergent dosing devices and particularly a device for metering detergent doses within a dishwashing machine. A detergent dosing device in accordance with an embodiment of the invention comprises: a water/wash liquor collection area (), a controlled inlet valve () for receiving water/wash liquor from the water/wash liquor collection area () and selectively allowing the collected water/wash liquor to pass through it, a housing partfor receiving water/wash liquor passed to it by the controlled inlet valve (), a detergent supply () for mixing with said water/wash liquor, a first sensor () for sensing the cleanliness level of water/wash liquor, a second sensor () for sensing detergent, a controller () for receiving signals from said first and second sensors () and for selectively controlling said inlet valve () on the basis of the outputs from the first and second sensors and an outlet () for dispensing mixed water/wash liquor and detergent.

Detergent dosing device

This invention relates to a dosage element of cleaning composition and an associated chamber for use in a ware washing machine, for example a dishwashing machine or a laundry washing machine. The dosage element and chamber are particularly useful in the context of forming part of a multi-dosing detergent delivery device and/or a refill for such a device. The element supports various different configurations of ingress and egress holes for an efficient dissolution of cleaning composition.

Dosage element and chamber

An article comprises a rack of solid sticks () of dishwasher detergent, retained on a backing material () and being formable into a nested, preferably cylindrical, form. The nested article is inserted into a holder, which is a plastics body, rigid and substantial. The holder is a permanent article located in use in a dishwasher but the article is a refill. Wastage of material when it is exhausted is minimal.

Multiple dosing ware washing article

The invention relates to a multi-dosing detergent delivery device. In embodiments of the present invention, the device comprises a housing () for receiving a cartridge (). The cartridge () has a plurality X of chambers (), each accommodating a detergent composition. The device further includes a directing means () to direct wash liquor selectively into a chamber () of the cartridge () to contact the detergent composition within it, and an outlet to allow the detergent loaded wash liquor to exit the device. The device also includes indexing means () for causing automatic movement of the cartridge () relative to the directing means () during and subsequent to a wash cycle so as to cause a neighboring chamber () to be exposed prior to a next washing cycle.
