Abstract: A method for managing the load of washing liquid in a laundry washing machine (100) is provided. The laundry washing machine has a washing tub (110), in which washing liquid may be loaded, and a rotatable drum (115), rotatably accommodated in the washing tub (110), for containing the laundry to be washed. The method includes performing a sequence of partial loads of washing liquid into the washing tub (110). Each partial load provides for loading a corresponding liquid amount in the washing tub (110). For at least one of the partial loads in the sequence, the method provides for loading into the washing tub (110) a predetermined amount of washing liquid which depends on at least one indicative parameter related to one or more of the previous partial loads in the sequence.

Abstract: A method is provided for treating laundry in a laundry washing machine. The method includes at least one washing phase during which the laundry is washed with introduction of water and the detergent into a washing tub and tumbled by rotation of a washing drum, at least one successive draining phase for draining liquid from the washing tub and following the draining phase at least one rinsing step in which the laundry is soaked with water, and a final rinsing step in which the laundry is treated by means of a rinse additive. An additive supply step is also included, where water is introduced into the tub together with the additive. Before the additive supply step, in a saturation step, the laundry is provided with a saturation amount of water for saturating said laundry.

Abstract: The present invention relates a to a method for washing laundry in a laundry washing machine comprising a washing tub external to a rotatable washing drum suited to receive laundry; the method comprises loading laundry into the washing drum and a laundry wetting phase for this laundry. The wetting phase comprises the steps of: —filling the washing tub with a first quantity of clean water at least equal to the quantity of water necessary to wet the loaded laundry completely, so as to obtain the complete wetting of the loaded laundry; —if a quantity of free water is present in the washing tub, externally to the laundry, draining from the washing tub this quantity of free water; —adding a given quantity of detergent to the loaded laundry.

Abstract: A method for operating a washing machine (10) having a washing tub (24) containing a laundry drum (26). The method has the steps of: detecting a liquid level (44) in the washing tub (24) and/or in a draining region thereof while the laundry drum (26) is rotating at a first speed, comparing the detected liquid level (44) with an upper threshold value (48), wherein the excess of said upper threshold value (48) by the liquid level (44) while the laundry drum (26) rotates at a rotation speed equal or higher than the first speed generates a closed liquid ring at circumferential walls of the laundry drum (26), and if the detected liquid level (44) exceeds the upper threshold value (48), then reducing the rotational speed of the laundry drum (26) below the first speed and performing a foam-detecting procedure for detecting the amount and/or presence of foam inside the washing tub (24) and/or in the draining region thereof.

Abstract: Household-type front loading and water-recirculating clothes washing machine adapted to automatically measure the weight of the dry clothes loaded in the machine for washing, also on the basis of the information on the type of clothes in said washload entered from the outside (user), in which the measurement of such weight of the washload is performed by measuring the amount of water that is absorbed by the clothes in the washload when this is soaked with water to a point at which it is in a dynamic saturation, i.e. steady-state condition. Said measurement of the amount of water absorbed in the clothes is obtained by subtracting the amount of water that is present in the machine, and that does not interact with the washload, from the total amount of water let into the wash tub. The weight of the load of clothes is finally calculated by processing and interpolating the amount of absorbed water and rectifying such value with an information on the properties of the clothes in the washload.

Abstract: A washing machine or washer-dryer (1) includes a washing tub (2), a laundry drum (3) within the washing tub (2) and a circulation pump (14) for pumping up water from a bottom region of the washing tub (2) into a higher region of the washing tub (2). A method of operation includes the step of detecting, determining and/or inputting the amount of laundry (4) in the laundry drum (3). The circulation pump (14) is deactivated, if the amount of the laundry (4) in the laundry drum (3) exceeds a predetermined threshold value. The washing machine or washer-dryer (1) may further include a control device (7) for controlling the circulation pump (14), and means for detecting, determining and/or inputting the amount of laundry (4) in the laundry drum (3). The circulation pump (14) is automatically switched off by the control device (7) if the amount of the laundry (4) in the laundry drum (3) exceeds a predetermined threshold value.

Abstract: Household-type front loading and water-recirculating clothes washing machine adapted to automatically measure the nature of the dry clothes loaded in the machine for washing, in which the measurement of such weight of the washload is performed by measuring the amount of water that is absorbed by the clothes in the washload when this is soaked with water to a point at which it is in a dynamic saturation, i.e. steady-state condition. Said measurement of the amount of water absorbed in the clothes is obtained by subtracting the amount of water that is present in the machine, and that does not interact with the washload, from the total amount of water let into the wash tub. The nature of the load of clothes is finally calculated by processing and interpolating the amount of water that is released by said load with respect to the water previously absorbed, and comparing said data with corresponding data relevant to reference textiles, whose nature is known.
