Definitions

  • the invention relates to a laundry product dispensing device for placing in the drawer of a washing machine.
  • the invention further relates to use of said device in the laundering of articles such as clothing.
  • washing machines are used for laundering articles, such as clothes and household linens.
  • Laundry products including detergent and often fabric conditioners, are added to the wash.
  • products are added via a drawer in the washing machine.
  • products are added directly to the drum, for example via a dosing ball.
  • Laundry products added via the drawer of the washing machine are added to the wash at a predetermined point in the wash program.
  • Laundry products are placed in channels (compartments) in the drawer, and water is run through these channels at the appropriate juncture en route to the drum of the washing machine.
  • the laundry product is solubilised/partially solubilised/suspended and carried with the water flow.
  • These channels are typically numbered/labelled to indicate the type of laundry product to be added to each channel.
  • Automatic machines typically have a “main wash” detergent channel, into which the laundry product used in the main wash cycle is added.
  • this “main wash channel” may be labelled “II” (with the prewash/additional benefit agent channel labelled “I”).
  • a further channel is provided for fabric softener, which is typically labelled “*”.
  • Dispensing laundry products using a drawer of the washing machine ensures that the laundry products are dosed into the drum at a specific time, such as, for example dispensing fabric conditioner into the drum in the final rinse.
  • the present invention seeks to address some of the problems associated with using washing machine drawers to dispense laundry products. It further addresses the potential over-/under-dosing of laundry products by consumers who may be tempted to “pour just a bit more in” leading to waste and sometimes, counter-intuitively, potential loss of performance.
  • the invention relates to a laundry product dispensing device for placing in a washing machine drawer.
  • the device houses laundry product in a chamber and has a sensor configured to detect the presence of water in a channel in the drawer. This enables the device selectively to dispense laundry product from the chamber only when it is determined that water is present in the channel in the drawer. The laundry product is then carried to the drum by the water flowing through the drawer channel.
  • the invention relates to a laundry product dispensing device for placing in a washing machine drawer, the device having a chamber for housing laundry product, a dispensing mechanism for dispensing a unit dose of laundry product from said chamber into a channel in the washing machine drawer, and a water sensor; wherein the device is configured to actuate the dispensing mechanism when the water sensor detects water in said channel.
