Method of determining a laundry load size in a laundry treating appliance comprising a rotatable drum at least partially defining a treating chamber for receiving laundry for treatment in accordance with a treating cycle of operation, an imaging device, and a controller having a processor, the method includes generating an image, detecting markings in the generated image, and determining, by the controller, a load size based thereon.

A washing machine is provided. The washing machine includes: a washing/dewatering drum for accommodating the washings; an electric motor for driving the washing/dewatering drum to rotate; and a microcomputer. In a rinsing process of a washing operation in a water saving mode, the microcomputer continuously performs a dewatering-rinsing process for a plurality of times rather than executing a water-storage rinsing process for rotating a rotating wing while water stored in the washing/dewatering drum reaches a specified water level. The dewatering-rinsing process includes: a water supplying process of supplying water to the washing/dewatering drum so that the washings are saturated by water, and an intermediate dewatering process or a final dewatering process executed immediately after the water supplying process. A maximum rotating speed of the motor in the intermediate dewatering process immediately before the water supplying process is lower than a maximum rotating speed of in the final dewatering process.

A method for controlling a laundry washing machine. The method includes: performing a tub loading process comprising operating supply valve(s) to provide a first volume of water through a detergent supply system and into a tub to fill the tub with wash liquid; performing a washing process comprising rotating a drum to agitate laundry in in the presence of the wash liquid; performing a static rinsing process comprising operating a pump to remove a free volume of wash liquid from the tub without rotating the drum; and performing one or more rinsing processes comprising: operating the supply valve(s) to provide a volume of clean rinse water to the tub, operating the pump to remove the rinse water from the drum, and operating the motor to spin the drum at high speed to extract rinse water from the laundry, while continuing to operate the pump.

The present invention relates to a process for washing fabrics in the drum of an automatic washing machine.

A process for washing fabrics including the steps; a) contacting fabrics to be washed and a wash liquor in the drum of an automatic washing machine; b) washing the fabrics in the wash liquor in an automatic washing machine process, where the automatic washing machine process includes at least a main wash step; where the wash liquor includes; i) between about 0.5 ppm and about 5 ppm acyl hydrazone bleach catalyst; ii) between about 10 ppm and about 2500 ppm non-soap surfactant; iii) between about 50 ppm and about 2500 ppm of a hydrogen peroxide source, and where the wash liquor has a pH between about 6 and about 9.

A washing machine has a reservoir configured to hold materials to be washed, the reservoir positioned to receive water from a water source, a drain pipe connected to the reservoir, at least two cleaning agent dispensers, a controller connected to the cleaning agent dispensers, the controller arranged to control water flow into and out of the reservoir, and dispensing of agents from the cleaning agent dispenser, and at least one sensor arranged to sense contents of one of either the water or materials to be washed and communicate the contents to the controller, the controller to dispense cleaning agents based upon the contents. A method of dispensing cleaning agents includes receiving signals from at least one sensor, wherein the signals provide information about soil in a reservoir, using the information to select appropriate cleaning agents from a set of cleaning agents, and dispensing selected cleaning agents into the reservoir.

A method of laundering fabric including: (a) calculating a final amount of water to be added to a final wash bath; (b) calculating the amount of energy needed to heat this final amount of water to a desired final temperature; (c) contacting an amount of water that is less than the final amount water with fabric to form an intermediate wash bath, wherein a detergent composition is contacted to the fabric during the formation of the intermediate wash bath, or prior to the formation of the intermediate wash bath; (d) heating the water that contacts the fabric during (c) with the energy calculated in (b) such that the intermediate wash bath has a temperature above the desired final temperature; (e) washing the fabric in the intermediate wash bath for at least 3 minutes; (f) contacting the remaining amount of water to the intermediate wash bath to form the final wash bath having the desired final temperature; (g) washing the fabric in the final wash bath for at least 5 minutes; and (h) rinsing the fabric.

The invention provides a method for the cleaning of a soiled substrate, the method comprising treating the substrate with a non-polymeric solid particulate cleaning material and wash water, the treatment being carried out in an apparatus comprising a drum comprising perforated side walls and having a capacity of between 5 and 50 liters for each kg of fabric in the washload, wherein the solid particulate cleaning material comprises a multiplicity of non-polymeric particles at a particle to fabric addition level of 0.1:1-10:1 by mass, each of the particles being substantially cylindrical or spherical in shape, and wherein the drum comprising perforated side walls is rotated at a speed which generates G forces in the range of from 0.05 to 900 G. The non-polymeric particles may comprise particles of glass, silica, stone, wood, or any of a variety of metals or ceramic materials. Preferably the solid particulate cleaning material additionally comprises a multiplicity of polymeric particles each of which is substantially cylindrical or spherical in shape. Preferably, at least one detergent is employed in the cleaning process. The invention provides optimum cleaning performance as a result of improved mechanical interaction between substrate and cleaning media and is preferably used for the cleaning of textile fabrics. The method allows for significant reductions in the consumption of detergents, water and energy when compared with the conventional wet cleaning of textile fabrics, and also facilitates reduced washing-related textile fabric damage. The invention also envisages a cleaning composition comprising a solid particulate cleaning composition and at least one additional cleaning agent.

The disclosure relates to a method of washing textiles in a washing machine having a washing chamber for accommodating a washing liquid and textiles to be cleaned and having an activating unit possessing an inlet or introduction of washing liquid from the washing chamber into the activating unit and possessing an outlet for guiding washing liquid out of the activating unit into the washing chamber, and additionally having at least one means of activation suitable for setting in motion a process for forming free radicals in the washing liquid within the activating unit, wherein the washing liquid comprises an organic bleach booster compound, especially a zwitterionic 3,4-dihydroisoquinolinium derivative.

The present disclosure relates to a method for washing laundry of a laundry load, in particular in a washing drum (B2), carried out by at least one device (100, 200). In one example, the method includes generating steam and applying the steam to the laundry of the laundry load; producing a microemulsion by employing a detergent composition; and washing the laundry of the laundry load using a first wash liquor based on the microemulsion.
