  • Washing machine incorporating a bleach activator
    Patent number: 6513180
    Abstract: A washing machine including an metal-containing bleach activation system and method of operation are disclosed herein. A peroxide generator, in the form of an electrochemical cell, is connected to a water inlet pipe to produce and deliver peroxide molecules into the washing machine. The activation system includes a catalyst which is preferably compounded into structure of the machine, such that when soiled articles contact the peroxide and the catalyst, the bleaching activity of the peroxide is greatly increased.
    Type: Grant

  • Clothes dryer with emissive coating
    Patent number: 6223452
    Abstract: An improved clothes dryer has a rotatable drum with an emissive coating on the drum to reflect energy from a heat source, such as a radiant infrared lamp, inside the dryer. By reflecting the energy inside the rotatable drum, the rate of heat transfer is increased, thus increasing drying rate and increasing the energy efficiency of the dryer. Convection air can be used in combination with the infrared heat to further enhance drying.
