20090235466 | WASHING MACHINE SPRAY DEVICE AND METHOD - A washing machine includes a cabinet, a tub positioned within the cabinet, a basket rotatably supported within the tub, and a spray device mounted within the cabinet and positioned to introduce water into the basket. The spray device sprays an initial amount of water onto a wash load received in the basket. The rotatable basket is rotated to redistribute the wash load radially outwardly in the basket. The wash load within the basket is washed after the rotatable basket is rotated to redistribute the wash load. | 09-24-2009 |
20090265863 | ADAPTIVE DRAIN ALGORITHM FOR CLOTHES WASHERS - This disclosure is related to a system and method which minimizes the period of time in which a drain pump is running in a washing machine unit. The method includes determining the amount of washer fluid used to fill a washing machine tub when the washing machine has entered the draining portion of the cycle, measuring the time it takes in order to trip a water level sensor. The method generally continues with calculating a predicted time to drain and operating a drain pump according to the predicted time to drain. Use of this method minimizes the opportunities for machine malfunctions while further minimizing the opportunity for the pump to run dry, creating noise and increasing the length of the entire washing cycle. | 10-29-2009 |
20090293203 | DISPENSER AND DISPENSING METHOD FOR PULSATOR WASH SYSTEM - A dispenser and dispensing method for a pulsator wash system or machine includes an inner cup defining an inner chamber for receiving an additive and an outer cup defining an outer chamber annularly disposed about the inner cup. The inner and outer cups are disposed within a pulsator hub of the pulsator washing machine. In operation, an additive is added to the inner chamber and the wash tub of the pulsator washing machine is filled with water, wherein that water enters and rises within the outer chamber. A predetermined amount of the water in the outer cup is permitted to enter the inner cup to pre-dilute the additive. | 12-03-2009 |
20090293554 | PULSATOR WASH SYSTEM - A pulsator wash system includes a cabinet, a wash tub supported within the cabinet, a wash basket supported within the wash tub, and a drive system for rotating the wash basket. A pulsator is disposed adjacent a bottom of the wash basket and drivingly connected to the drive system. The pulsator includes a base portion, a central hub extending upward from the base portion, and a plurality of radially extending vanes extending upward from the base portion. Each of the plurality of radially extending vanes extends radially from about a peripheral radial edge of the base portion to a location spaced apart from the central hub. | 12-03-2009 |
20120120386 | WATER COLOR SENSING HARDWARE AND METHODOLOGY FOR APPLIANCES - Apparatus and methodologies are provided to selectively activate a liquid usage option in a washing apparatus based on the color of the liquid. Light from different light sources is passed through a liquid to be tested and the intensity of the light passing through the liquid is measured. The measurement is adjust based on a measurement of the turbidity of the liquid and the measurement compared to a reference value derived from measurements of a clear liquid. A decision is made based on the adjust measured color of the liquid regarding retention of the liquid for further use in the washing apparatus. The liquid tested may correspond to grey water from a previous wash cycle. | 05-17-2012 |
20120180825 | CHLORINE GENERATING DEVICE AND RELATED DISHWASHER - An electrolytic sanitizer is disclosed for use in a dishwasher holding a salt solution, the dishwasher having a water rinse cycle. A spaced anode and cathode are provided in contact with the salt solution in the dishwasher. A source of current provides a voltage across the anode and cathode to generate chlorine from the salt solution, the chlorine being introduced into the water rinse cycle to sanitize objects in the dishwasher. Related dishwasher designs are also disclosed. | 07-19-2012 |
20120266387 | APPARATUS AND METHOD FOR SENSING AND ADDING DETERGENT TO WATER FOR A WASHING MACHINE APPLIANCE - A method and apparatus for determining the amount of detergent in water used in a washing machine and to supplementing such water as needed for a wash load is provided. The amount of detergent present in grey water that is reused for washing, as well as the amount released from clothes or other articles to be washed, can also be determined. | 10-25-2012 |
20120266388 | FABRIC SOFTENER SENSING AND REUSE OF GREY WATER FROM THE RINSE CYCLE OF A WASHING MACHINE - The capture and reuse of the effluent, or grey water, from the rinse cycle of a washing machine appliance is provided. A determination is made regarding whether fabric softener is present in the effluent. If fabric softener is present, then the effluent can be reused during a rinse cycle of the washing machine so as to avoid undesirable interaction between the fabric softener in the effluent and the detergent of a rinse cycle. | 10-25-2012 |
20130153512 | TREATMENT OF SURFACTANT LADEN WASTEWATER - Clarification of surfactant laden wastewaters of the type commonly encountered in the laundry, dishwashing, textile manufacturing, and metal cleaning and degreasing processes is provided by use of a chitosan/(meth)acrylyloxy alkyl quaternary ammonium salt graft polymer. | 06-20-2013 |
