  • Patent number: 10400377
    Abstract: A method for controlling a wash process in a washing appliance includes supplying a detergent in the washing appliance; detecting a type of detergent supplied; performing a wash cycle that ends with a washing liquor drain; and performing a rinsing cycle in accordance with the detected type of detergent. When the detected detergent is a powder detergent, water is introduced into the washing chamber for a first rinsing step. Between the washing liquor drain and the first rinsing step, laundry is tumbled in the washing chamber at at least one of a revolving speed lower than a minimum spinning speed so that no spinning is performed between said washing liquor drain and the first rinsing step, or for a time interval different from the corresponding time interval during which the laundry is tumbled in a rinsing cycle where a liquid or gel detergent is detected.

  • Patent number: 8490439
    Abstract: In a laundry washer, relatively short bursts of operation of a recirculation pump are coordinated with corresponding brief intervals of tub rotation during the initial fill periods. The aim is to thoroughly wet the clothes early in each wash/rinse phase to thus improve the wash/rinse effectiveness, while also avoiding excessive suds formation. Following the initial fill periods and during regular wash/rinse agitations, the recirculation system may also be employed to “recharge” the laundry load with detergent that has settled in the bottom of the tub. In a further aspect of the invention, some or all of the conventional intermediate spin extractions are omitted. In this manner, more water is carried over in the clothes from one wash/rinse cycle to the next. An intermediate spin of reduced speed (RPM) and duration as compared to typical normal intermediate spins may be employed between the wash phase and first rinse.

    Abstract: A washing machine 10 of the drum type comprises a drum 20 rotatable about a horizontal or inclined center of rotation, a drive motor 50 for rotating the drum, liquid holding chambers 36 for holding a liquid therein centrifugally, means for detecting an eccentric load of laundry in the drum, and control means 72 for adjusting the amounts of liquid in the chambers in accordance with the detected eccentric load. The amounts of liquid in the chambers are adjustable by braking the drum in rotation. The machine has moment of inertia measuring means 60 for detecting the rotation of the drum. The control means calculates the moment of inertia acting on the drum based on the rotation of the drum detected by the moment of inertia measuring means, and adjusts the magnitude of braking force to be applied to the drum in accordance with the calculated moment of inertia so as to decelerate the drum at a constant rate in adjusting the amounts of liquid in the chambers.

  • Publication number: 20040211228
    Abstract: When an operation for washing is completed and door is unlocked, water level in a water tank is monitored only for a prescribed time period. When there is no water leakage, monitoring is stopped after the prescribed time period and the power is turned off. When there is a water leakage, water level in the water tank increases. When it is detected that a first water level is reached, the door is locked to prevent opening. After a prescribed time period, the power is turned off while the door is kept locked. If the door cannot be locked, the door lock error is notified and the water collected in the water tank is drained.

  • Publication number: 20040139557
    Abstract: Disclosed are a method for controlling a driving of a drum type washing machine preventing vibration and noise of a drum, reducing a usage of washing water, and reducing rinse time, and an apparatus thereof. To this end, the drum is rotated with a preset equilibrium speed faster than a speed that vibration of the drum is excessively generated accordingly as a rotation speed of the drum is decreased when a dewatering process of laundry is completed, and washing water is supplied into the drum type washing machine while maintaining the drum as the preset equilibrium speed.

  • Patent number: 6701561
    Abstract: Methods and systems are disclosed for detecting mass transfer in a rotating device or rotating system, such as a washing machine or dishwasher. Mass may be transferred from the stationary member to the rotating member. The transfer of the mass from the stationary member to the rotating member may be detected utilizing a sensor. A controller linked to the rotating system thereafter may receive a signal that the transfer of mass has been detected, in response to detecting the transfer of mass, thereby permitting the controller to compensate future mass placements in the rotating system according to measured latencies. The mass may comprise a fluid. The fluid itself may be conductive. A gap is generally configured between the stationary member and the rotating member. At least one wire connected to the sensor may be inserted into a stream of such fluid that is created when injectors are activated.

  • Patent number: 6681430
    Abstract: A method and system for dynamically balancing a rotating system based on a plurality of simultaneous and discrete control actions that place mass at predetermined locations within the rotating system so as to achieve balance is disclosed. A balance control algorithm may be utilized to provide a desired control action regarding an amount of mass to be placed, the extent each discrete action contributes, and the location of placement on the rotating system. The control action is broken down into subsets of discrete actuator steps whose whole will accomplish the desired control action. The composition of the actuator step subsets is based on particular ratios and limits and evolve based on the portion of the action already accomplished. A plurality of control actuators is simultaneously activated to deploy the discrete control actuator actions that place mass at predetermined locations within the rotating system.

  • Patent number: 6658902
    Abstract: A dynamic balancer for an automatic washer includes an annular hollow first chamber. A first fluid is held within the first chamber and only partly fills the first chamber. An annular hollow second chamber is disposed adjacent to the first chamber and includes a plurality of objects disposed therein which are movable along the chamber. A second fluid is also held in the second chamber and, in combination with the solid bodies, only partly fills the second chamber. The first fluid in the first chamber produces a first balancing characteristic of the dynamic balancer. The movable objects within the second chamber produce a second balancing characteristic of the dynamic balancer. The second fluid held in the second chamber also produces a third balancing characteristic of the dynamic balancer.

  • Publication number: 20010052249
    Abstract: This invention relates a control for an automatic washer incorporating a spray pretreatment or stain care cycle. In order to manage the occurrence of the condition of suds lock, the state of the washing machine related to the suds lock condition during spray pretreatment is determined by one or more of a number of methods. With this information concerning the state of the spray pretreatment process, the occurrence of suds lock can be ascertained and the cycle can be controlled accordingly to minimize negative effects resulting from a prolonged suds lock condition. Additionally, with certain information related to the occurrence of suds lock, steps can be taken during the spray pretreatment portion of the cycle to avoid the condition of suds lock altogether. Using the same primary process for measuring suds lock, load size can also be ascertained. Information about load size can be used to control the wash cycle.
