Definitions

  • US 2005/0224098A1 discloses one such technique to improve cleaning performance.
  • This document discloses a tableware cleaning method that utilises a fine mist of a cleaning fluid to enhance cleaning. The content of this entire document is hereby incorporated by reference. It was found that atomising a cleaning fluid into a mist and allowing the mist to contact the soiled tableware provided enhanced cleaning performance over traditional aqueous detergent solution techniques.
  • It is an object of the present invention to provide an improved method of cleaning tableware in an automatic dishwashing machine comprising:
  • a dishwasher comprising a device capable of atomising a cleaning product, wherein the device is capable of atomizing the cleaning product such that greater than 95% of the particles are less than 2 microns in diameter.
  • the improved cleaning performance of the finer mist may reduce the both the temperature and the quantity of the cleaning fluid used in a subsequent rinsing step.
  • the finer atomisation also allows for the use of less chemical cleaning product as this is dispersed much more efficiently.
  • WO2008149073 discloses a device suitable for generating atomised mists with the desired particles size of the present invention.
  • the disclosure of these documents is herein incorporated by reference.
  • a smaller version of these can be installed into a dishwasher. Or a smaller version may be designed as a standalone device designed to be incorporated into different machines.
  • the misting device is designed to be inbuilt into a dedicated dishwashing machine.
  • the device can be designed as a standalone unit for incorporation into a wide range of different dishwashing machines.
  • the smaller particle size aids penetration of the atomized cleaning product into the food soils and greatly facilitates its release. Without wishing to be bound by theory it is believe that this may be the result of the smaller particles being readily able to enter much smaller pores in the food waste.
  • mist of cleaning product with the smaller particle size also provides for a shortened hold sequence in the cleaning while the mist works on the food stains. This allows for a much more rapid overall cleaning cycle.
  • Any usual detergent product may be used in the described method as the cleaning product.
  • suitable detergent products include an alkaline agent, a surfactant, an enzyme, and a bleaching agent.
  • the surfactant may be anionic, cationic, zwitterionic, or non-ionic.
  • the enzyme may be a protease or an amylase.
  • the bleaching agent may be organic or non-organic.
  • the cleaning product may a single entity. Or the cleaning product may be a complex mixture, of different ingredients.
  • anionic surfactants have to be avoided due to the dangers of foaming.
  • they may be used as foaming is not an issue in a mist.
  • mist allows for potentially more expensive components as much smaller amounts of material may be needed than in conventional water solution washing. This is because they are not being dissolved in large amounts of wash water.
  • ionic liquids maybe used in the present invention. These are known to have good cleaning properties but are very expensive. They also have the problem that if diluted in water they revert back to salts and so they cannot normally be used in a standard dish washer. With the misting system of the present invention, the distribution of neat undiluted ionic liquid over the tableware can be achieved.
  • suitable ionic liquids may be found in US 7,928,053.
  • the detergent product may be used alone or dissolved in a suitable carrier prior to atomisation.
  • a suitable carrier may be a solvent.
  • suitable solvents include water, and ethanol.
  • the cleaning fluid used in the second step may be water or it may be another solvent. It is preferred that the fluid comprises water.
  • the cleaning fluid may be solely a solvent such was water, or the cleaning fluid may comprise further detergent or rinsing chemistry.
  • the cleaning fluid may further comprise detergent compositions that comprise one or more of the following ingredients:
