Appl. No.:

09/520653

Inventors:

Kurt A Estes - Lake Zurich IL
Daniel C. Conrad - Stevensville MI
Mark Bradley Kovich - St. Joseph MI
Tremitchell L. Wright - Granger IN

Assignee:

Whirlpool Patents Co. - St. Joseph MI

International Classification:

D06B 1300

US Classification:

8142, 81492, 8158

Abstract:

Methods and apparatuses for washing fabric loads without water or using water only as a co-solvent are disclosed. One method of non-aqueous clothes washing includes the steps of disposing clothing in a wash container, delivering a wash liquor to the fabric load, the wash liquor comprising a substantially non-reactive, non-aqueous, non-oleophilic, apolar working fluid and at least one washing additive, applying mechanical energy to the clothing and wash liquor for a sufficient amount of time to provide fabric cleaning and, thereafter, substantially removing the wash liquor from the fabric load. The working fluid may be selected from the group consisting of perfluorocarbons, hydrofluoroethers, fluoronated hydrocarbons and fluoroinerts.

Assignee:

Whirlpool Corporation - Benton Harbor MI

International Classification:

D06F 1900

US Classification:

68 5C, 68 18 C, 68 18 F, 68205 R

Abstract:

The present invention relates to an automatic washing apparatus for dry laundering hanging garments. The automatic washing apparatus has a sealed wash cabinet and a working fluid storage chamber for storing an amount of working fluid sufficient to dry launder a fabric load. The working fluid storage chamber is in fluid communication with the sealed wash cabinet. The sealed wash cabinet has an interior region, an upper assembly above the interior region, a lower assembly housed below the interior region and a door sealing the interior region of the wash cabinet. The upper assembly shakes the hanging garments in the wash cabinet and dispenses a wash a working fluid into the wash cabinet. The lower assembly has a moisture generator and a heater to respectively generate moisture and heat inside the wash cabinet.

International Classification:

D06F 33/00

US Classification:

68 1206, 8159

Abstract:

A method of determining an imbalance condition in a horizontal axis washing machine comprises several steps, including establishing a speed profile for the washing machine, having at least three increasing speed steps, operating a motor to rotate the washing machine drum sequentially through the three speed steps, measuring the power output of the motor at each speed step, calculating an average power output by averaging the power output at the first and second speed steps, calculating the difference between the power output at the third step and the average power output, comparing the difference to a predetermined threshold difference value, and sending a signal indicative of an imbalance condition if the difference exceeds the threshold difference value.

Abstract:

An improved solvent cleaning process of cleaning a non-aqueous solvent used in a dry cleaning process for fabrics including consecutive wash cycles for washing respective fabrics batches, including a basic solvent refining cycle and a first advanced solvent refining cycle, the basic solvent refining cycle including a step of separating solvent into a first solvent fraction and a second solvent fraction which is less clean than the first fraction, wherein the basic and first advanced solvent refining cycles are independently effected when solvent to be cleaned fulfils a respective predetermined condition.
