Abstract: A method and system for providing washing machine operation information.

Abstract: A method and apparatus for predicting load unbalance in an appliance is provided for an appliance having a vessel configured to receive a supply of material and rotatable about an axis. A control is arranged and configured to rapidly accelerate a rotation of the vessel, determine an amount of energy with which the vessel has engaged the relatively stationary part, compare the amount of energy with a predetermined value and send a signal indicative of an unbalance condition if the amount of energy exceeds the predetermined value. The vessel may be rotated by use of an electric motor such as a controlled induction motor and the control can be used to measure the electric current drawn by the motor and through manipulation of the current, determine the amount of energy with which the vessel engages the stationary part of the appliance.

Abstract: A washing machine and a method of changing system data therein that can grasp causes such as trouble of the product itself, problems on installation, problems on the regional characteristics, living pattern change of a user, etc., and change/replace a pre-stored program to/by a wash-related program that can solve the problems. The washing machine includes an outer tank, an inner tank, a load section, a microcomputer for controlling drive of the load section and reading an operation state of the load section, a key input section, a display section, an interface section for sending/receiving wash-related data to/from an external device, and a memory for enabling data read/write and storing the program or data received from the external device.

Abstract: Sensor for detecting both a water level and a vibration in a washing machine, which permits detection both of the water level of washing water in a washing tub and the vibration of the washing tub, including a housing which is a body of the sensor for detecting both the water level and the vibration, hydraulic pressure transmission means under the housing for moving up and down by a hydraulic pressure of the water level in a washing tub, a coil part above the hydraulic pressure transmission means having a coil with a proper inductance, a core holder on the hydraulic pressure transmission means having a core accommodated therein, the core adapted to move up and down within the coil part for varying the inductance of the coil, a cap fitted to a top portion of the coil part, a spring placed in a hollow of the coil part, and a vibration detecting means adapted to move according to the vibration of the housing for varying the inductance of the coil, whereby detecting the water level in the washing tub by substanti

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.

Abstract: A laundry treatment machine, in particular, a washing machine and/or drier, includes an electronic controller, an information output device, and an input device. The electronic controller automatically implements laundry programs and has a decision-maker identifying each laundry item placed therein. The decision-maker makes decisions to create an optimized treatment program for treating the combination of identified laundry items placed into the machine. An information output device presents to a user the optimized program as a proposal. An input device is connected to the electronic controller and is to be actuated by a user for confirming the laundry treatment program determined by the decision-maker.

Abstract: A communication-controlled washing system and a method for operating the same, wherein at least one washing machine is remotely controllable through a communication unit. A service provider controls the use, operation completion, operation progress and fault diagnosis of a plurality of washing machines individually over a communication network, resulting in a significant reduction in time and effort required for users or managers to limit the use of machines, upgrade programs or repair faults. Further, the optimum washing mode can be performed according to a use history and environmental conditions of each machine.

Abstract: A drum type washing machine includes an outer cabinet, a water tub mounted in the outer cabinet and having a rear wall, a generally drum-like rotating tub rotatably mounted in the water tub and having a rear wall, and a turbidity sensor sensing a turbidity of wash liquid in the water tub and disposed on a lower inside face of the rear wall of the water tub, the turbidity sensor including a light emitting element and a light detecting element.
