摘要:
The present invention relates to a method for washing laundry during a washing cycle in a laundry washing machine (1) comprising a washing drum (4); a washing tub (3) external to the washing drum (4); a water supply unit (5) to supply water (W) into the washing tub (3); an automatic dosing device (58) comprising a compartment suitable for receiving a quantity of detergent (D) sufficient for a plurality of washing cycles; a recirculation circuit (30) and a concentration sensor device (80). The method comprises the steps of: introducing a first prefixed quantity (Q1d) of detergent (D) and a first prefixed quantity (Q1w) of water (W) into the washing tub (3); activating the recirculation circuit (30) for mixing the first prefixed quantity (Q1d) of detergent (D) with the first prefixed quantity (Q1w) of water (W); determining the current concentration value (V) of the detergent (D); comparing the current concentration value (V) with one or more prefixed concentration levels (T1, T2) and either introducing or not introducing a second quantity (Q2d) of detergent (D) into the washing tub (3) according to the result of the comparison. The first prefixed quantity (Q1d) of detergent (D) and/or the second quantity (Q2d) of detergent (D) is determined on the base of the amount of laundry load (L). (FIG. 2)

The present invention relates to a method to control a washing machine (1), the washing machine including a tub (5) and a drum (6), the drum (6) being rotatably mounted inside the tub (5) and apt to contain laundry to be washed, the method comprising: - setting a washing cycle among a plurality of washing cycles; - calculating a first weight of the laundry in the drum before water is supplied to the drum and/or tub; - comparing the first weight to a first threshold (T1); - if said first weight is above the first threshold (T1), then the method further includes: i. introducing water into the tub; ii. calculating a second weight of the laundry present into the drum; iii. determining a parameter of the set washing cycle on the basis of said second weight, independently from the first weight; iv. washing and/or rinsing said laundry.

The invention relates to a laundry treatment apparatus (2), in particular laundry dryer, washing machine or washer dryer, the laundry treatment apparatus comprising: a casing (3), a laundry storing compartment (17) arranged within the casing (3) for receiving laundry to be treated, a contactless laundry water content sensor (200) adapted to detect the amount of water contained in the laundry stored in the storing compartment (17), and a control unit for controlling the operation of the laundry treatment apparatus (2) and adapted to receive a signal from the laundry water content sensor (200). According to the invention, the control unit is either adapted to select or adjust one or more of the following parameters in dependency of the laundry water content sensor signal: estimated time to cycle end, drying air flow rate, drum rotation speed (tumbling or spinning), heat pump compressor operation parameters (speed, temporal profile), heating power, and/or self- cleaning operation. Preferably the control unit is adapted to receive a signal from a load detector (220), and wherein the control unit is adapted to process the signals from the load detector (220) and the laundry water content sensor (200) for determining a secondary parameter, which is depending on the load detector signal and the water content sensor signal and which is used by the control unit for controlling a drying and/or spinning operation of the laundry treatment apparatus (2).

The method comprises the steps of: introducing a first prefixed quantity (Qld) of detergent (D) and a first prefixed quantity (Q1w) of water (W) into the washing tub (3); activating the recirculation circuit (30) for mixing the first prefixed quantity (Qld) of detergent (D) with the first prefixed quantity (Q1w) of water (W); determining the current concentration value (V) of the detergent (D); comparing the current concentration value (V) with one or more prefixed concentration levels (T1, T2) and either introducing or not introducing a second quantity (Q2d) of detergent (D) into the washing tub (3) according to the result of the comparison. The first prefixed quantity (Qld) of detergent (D) and/or the second quantity (Q2d) of detergent (D) is determined on the base of the amount of laundry load (L).
