A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A camera assembly is used to monitor articles for washing within the wash basket. Specifically, a controller of the washing machine appliance uses the camera assembly to obtain a reference image and one or more test images, which utilize image recognition to assess turn-over of the articles for washing during a given wash cycle. When turn-over performance is inadequate, a controller may adjust one or more operating parameters of the wash cycle to improve performance. Turn-over performance of the wash cycle is determined to be adequate once the image recognition process fails to find adequate correlation between the reference image and the test image a predetermined number of times.

The invention relates to a method for operating a washing machine having a suds container for holding washing liquid, a non-ribbed drum rotatably mounted in the suds container for holding laundry, a motor for driving the drum, and a control device, wherein the method comprises a step for detecting when laundry is sliding and/or rolling, comprising, while rotating the drum, sampling a variable related to a torque of the motor or a rotational speed of the drum over a predetermined period of time; and determining whether the laundry is sliding and/or rolling in the drum based on the variable sampled over the period of time.

The invention further relates to a corresponding washing machine.

Method of determining a laundry load size in a laundry treating appliance comprising a rotatable drum at least partially defining a treating chamber for receiving laundry for treatment in accordance with a treating cycle of operation, an imaging device, and a controller having a processor, the method includes generating an image, detecting markings in the generated image, and determining, by the controller, a load size based thereon.

A method and apparatus for drying a wet textile article with a radio frequency (RF) applicator and a controller, the method includes supplying a power level to the RF applicator to energize the RF applicator to generate a field of electromagnetic radiation (e-field), determining a dynamic drying cycle of operation in the controller, and controlling the power level of the RF applicator according to the determination of the dynamic drying cycle of operation, wherein the wet article is dried.

A washing machine includes a machine housing, a tub that is suspended on a plurality of support arms in the machine housing, and a washing drum that is rotatably mounted in the tub, at least one of the support arms being equipped with a force sensor, which generates a force measurement signal that is representative of the force acting upon the respective support arm. Moreover, the washing machine is equipped with a level sensor, which generates a level signal that is representative of the water level in the washing drum, and an electronic control unit that processes the force measurement signal and the level signal, and which is configured to control the sequence of a washing program of the washing machine in dependence on the force measurement signal and the level signal.

The present invention relates to a clothes treating apparatus, including a door to open/close an accommodation space, a hanger provided in the accommodation space and having at least one clothes caught thereon, a sensing unit to sense information related to the clothes caught on the hanger, a controller to control an operation of the clothes treating apparatus based on the sensed information, and an input unit to receive a user input associated with the operation, wherein the controller determines whether a user input is applied to the input unit while a predetermined time interval elapses from a time point that the door has been opened and then closed, determines whether clothes have been added into the accommodation space when a user input is not applied during the lapse of the predetermined time interval, and performs a preset operation of the clothes treating apparatus when it is determined that the clothes have been added to the accommodation space.

The present invention relates to a clothes treating apparatus, including a communication unit to transmit or receive information related to a usage history of the clothes treating apparatus, a memory to store the information related to the usage history, an air supply device to heat air supplied into an accommodation space of the clothes treating apparatus, and a controller to extract a use time zone of the clothes treating apparatus based on the information related to the usage history, drive the air supply device in a preset pattern within the extracted use time zone, and stop an operation of the clothes treating apparatus at a time zone except for the extracted use time zone.

A laundry washing machine and method control a time or duration of a drain operation at least in part based upon a type of a load being washed in the laundry washing machine. By doing so, the amount of time in which a drain operation is performed may be customized for different types of loads, and in many instances, may reduce the amount of noise and/or energy consumption associated with draining a wash tub during a wash cycle.

A method of drying laundry in a laundry treating appliance having a treating chamber in which the laundry is received for drying comprises moving the treating chamber to redistribute the laundry, supplying air to the treating chamber to define a supply air flow, exhausting the supplied air from the treating chamber to define an exhaust air flow, actuating a heater at full output to heat the air supplied to the treating chamber, turning the heater off, and maintaining a maximum evaporation rate for a duration of time by operating the heater.

A clothes treating apparatus is provided that may include an accommodation chamber, in which an object may be accommodated; a first heat pump cycle having a first evaporator, a first compressor, a first condenser, and a first expansion valve; a second heat pump cycle having a second evaporator, a second compressor, a second condenser, and a second expansion valve, and arranged such that air introduced into the accommodation chamber passes through the first evaporator, the second evaporator, the second condenser and the first condenser, sequentially; and a controller configured to control an operation of the first and second heat pump cycles. At least one of the first compressor or the second compressor may be provided with an inverter that changes a drive speed of the compressor through a frequency conversion. The controller may drive the at least one of the first compressor or the second compressor within a predetermined drive range, by controlling the drive speed of the at least one of the first compressor or the second compressor using the inverter.
