  • Patent number: 7421752
    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.

  • Publication number: 20080172804
    Abstract: A washer fill system and method supply a suitable minimum amount of water necessary to wash a particular load of laundry based on readings taken from a pressure sensor that measures liquid pressure in the wash tub. During the fill period, water is initially sprayed over the load to evenly wet the clothes. As the clothes become saturated, excess free water collects at the bottom and begins to fill the tub. Pressure sensor readings are taken intermittently during the fill process to determine when a sufficient amount of free water for washing the load of clothes has accumulated in the tub. This includes pressure readings taken while pulsing the washer motor to spin the wash basket. Other pressure readings may be taken during a pause in filling to measure the water run-off from the wetted clothes above the free water line, and the release of air bubbles from a load portion below the water line.

    Abstract: A control system for a laundry washing machine with a horizontal wash drum detects load imbalance in the drum and selects a proper rotation speed for the drum in a water extraction operation. A drive controller for the motor turning the drum detects a phase angle variation in the drive voltage and drive current applied to the motor as an indication of the load imbalance in the drum, and determines whether the detected load imbalance falls in one of a plurality of pre-defined load-imbalance zones. The drive controller then provides a signal indicating the detected imbalance zone to a machine controller of the washing machine. The machine controller selects a proper rotation speed for the extraction operation based on the detected imbalance zone, or alternatively initiates a load-redistribution operation to reduce the load imbalance.

The pre-wash step can comprise recirculating a first volume of liquid between the tub and the drum without submerging a portion of the drum in the liquid and rotating the drum. In another embodiment, the pre-wash step can comprise recirculating a first volume of liquid between the tub and the drum to achieve a fabric load weight to liquid weight ratio of between about 1:0.5 and 1:2.7.

  • Publication number: 20070271708
    Abstract: Window cleaning cloths are repetitively conditioned for cleaning windows in a commercial car wash by processing the cloths in a washer-extractor of the type having in sequence a wash cycle, a first rinse and spin cycle and a final rinse and spin cycle. A detergent and degreaser are added to the water used in the wash cycle. A window cleaning solution is added to the final rinse water used in the final rinse and spin cycle to saturate the cloths with a diluted mixture of water and window cleaning solution. A substantial portion of the diluted mixture of final rinse water and window cleaning solution is removed during the spin portion of the final rinse and spin cycle to provide a window cleaning cloth uniformly dampened with window cleaning solution. The conditioned cloths are used to wipe windows without necessity of spray application of cleaning solution. The cloths are reprocessed and used in the same manner.

  • Publication number: 20070251023
    Abstract: A drum type washing machine has an access hole and a drum door for closing the access hole provided on the cylindrical sidewall of the drum. The enclosure of the washing machine includes an access opening that aligns with the assess hole of the drum. A motor of the washing machine is coupled to both the drum door and the drum itself. Thus, the motor can be used to rotate the drum and the door during washing operations. A clutch unit selectively couples and decouples the motor from the drum so that the drum door can be rotated with respect to the drum to open and close the access hole of the drum.

  • Patent number: 7287292
    Abstract: A washing machine control method prevents the setting of an incorrect water level, when laundry is added to the washing machine after manipulating a wash command key, by setting an accurate water level and wash pattern. The water level and wash pattern are repeatedly reset according to a differential present in consecutively sensed wet laundry amounts, if a substantial differential is detected between dry and wet laundry amounts. That is, if the difference between consecutively sensed wet laundry amounts is reduced to a predetermined value, within a predetermined number of repeated sensings, the washing step is controlled according to reset values for the water level and wash pattern.

  • Publication number: 20070220683
    Abstract: A nonvolatile semiconductor memory device which is superior in writing and charge holding properties, including a semiconductor substrate in which a channel formation region is formed between a pair of impurity regions formed with an interval, and a first insulating layer, a floating gate, a second insulating layer, and a control gate over an upper layer portion of the semiconductor substrate. It is preferable that a band gap of a semiconductor material forming the floating gate be smaller than that of the semiconductor substrate. For example, it is preferable that the band gap of the semiconductor material forming the floating gate be smaller than that of the channel formation region in the semiconductor substrate by 0.1 eV or more. This is because, by decreasing the bottom energy level of a conduction band of the floating gate electrode to be lower than that of the channel formation region in the semiconductor substrate, carrier injecting and charge holding properties are improved.

    Abstract: A washing machine and washing control method thereof. The washing control method not only improves the effectiveness of a preliminary washing cycle that is an optional function of the washing machine, but also reduces the amount of detergent and wash water that is used for the preliminary washing cycle. For this, the washing control method includes determining whether or not a preliminary washing cycle is selected, supplying a lesser amount of wash water than a desired amount of wash water that is determined based on the amount of laundry if the preliminary washing cycle is selected, and performing the preliminary washing cycle, and supplying a certain amount of wash water additionally after completing the preliminary washing cycle, and performing a main washing cycle.
