Abstract
Two or more permanent magnets (2, 3) are sandwiched between two complimentary plastic plates (1) sealed together and disposed in a protective outer cover (20). The device is placed in the wash water of a laundry machine, where its magnetic field induces eddy currents that soften the water. As an alternative, battery powered circuitry may be provided to generate a radiated electromagnetic field, with a similar cleaning enhancement effect.
Claims9
A device for enhancing the cleaning of laundry items, comprising:
- a) a water-proof housing (1) consisting of essentially electromagnetically neutral material, and
- b) means for producing a magnetic field disposed within the housing, the device being adapted to be placed in wash water in a laundry machine,
- c) wherein the housing is flared on the outside,
- d) wherein the flaring is formed by a basket-shaped protective cover (20) with a plate-like interior, and
- e) wherein the housing is constructed flat and plate-like, and is snugly disposed in the plate-like interior.
