METHOD FOR CONTROLLING LAUNDRY TREATMENT APPARATUS
A method for controlling a laundry treatment apparatus is disclosed. The laundry treatment apparatus includes an upper treatment device and a lower treatment device. The upper treatment device includes a drying drum in which target laundry to be dried is placed, an upper driver to rotate the drying drum, a circulation passage unit through which air flows into or out of the drying drum, a heat exchanger to dehumidify and heat the air, and a steam generator to supply steam to the drying drum. The lower treatment device includes a tub to store wash water therein, a washing drum provided in the tub so that target laundry to be washed is put into the washing machine and the laundry is washed and dried, a tub heater provided in the tub to heat the wash water, and a lower driver to rotate the washing drum. The method for controlling the laundry treatment apparatus includes performing, by the lower treatment device, a washing course including a water supply step, a washing (rinsing) step, and a dehydration step, and performing, by the upper treatment device, a drying course including a hot air supply step, a fan operation step, and a dryness sensing step, wherein the lower treatment device performs the washing course by changing a configuration of at least one of an operation of the tub heater, an execution time of the washing course, and an operation of the lower driver according to a progress state of the drying course, thereby performing the washing course.
Drive unit of a laundry machine and laundry machine having the same, and a controlling method of the laundry machine
The present disclosure relates to a twin laundry machine, more particularly, to a twin laundry machine configured to control mutual motor operations of one or more laundry machines provided therein not to be overlapped with each other, in case the one or more laundry machines are put into operation to perform washing. The present disclosure also relates to a twin laundry machine of which a motor for driving a drum has an improved heat radiation function, more particularly, to a twin laundry machine which includes a sub-washing machine with a smaller size than a normal washing machine and frequent exposure to high temperature usage environments.
Use of external information in the operation of a household device
The present disclosure concerns a method for operating or controlling an operation of a household appliance (100, 300) performed by at least one device (100, 200, 300, 400). The method includes: obtaining external information representative of at least one external given situation outside the household appliance (100, 300); and operating or controlling an operation of the household appliance (100, 300) at least taking into account the external information obtained. In addition, the present disclosure concerns a device and a system for performing such a method.
Laundry treatment machine
Provided is a laundry treatment machine including a washing tub, a washing tub motor configured to rotate the washing tub, a drain pump configured to operate to drain the washing tub, a motor configured to operate the drain pump, a converter configured to output DC power, an inverter configured to convert the DC power, a dc terminal voltage detector configured to detect a dc terminal voltage output from the converter, and a controller configured to, when the dc terminal voltage continuously drops during a first period based on an operation of the inverter, perform control to turn off the inverter and operate the converter after the first period. Accordingly, it is possible to stably drive based on the dc terminal voltage during the operation of the drain pump.
ATOMISING GENERATOR, CLOTHING TREATMENT DEVICE, AND CONTROL METHOD THEREFOR
An atomizing generator, a clothing treatment device, and a control method therefor to solve the problems of the structural complexity and poor liquid level measurement accuracy of existing atomizing generators. The atomizing generator includes an outer shell and an atomizing module, an atomization cavity capable of accommodating liquid being disposed in the outer shell, and a liquid inlet, an air inlet, and a mist outlet in communication with the atomization cavity being arranged on the outer shell, the atomizing module including an ultrasonic atomizing sheet, and the atomizing module being arranged to be capable of atomizing the liquid in the atomization cavity by vibration of the ultrasonic atomizing sheet and detecting the height of the liquid level in the atomization cavity by the vibration, which simplifies the structure of the atomizing generator and increases the precision and accuracy of liquid level measurement.
METHOD OF USING IMAGE RECOGNITION PROCESSES FOR IMPROVED OPERATION OF A LAUNDRY APPLIANCE
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 basket speed sensor monitors the speed of the wash basket and a camera assembly is mounted within the wash tub for taking images of the load of clothes during and/or after a wash or rinse cycle. A controller determines the basket speed, adjusts a frame rate of the camera assembly to match the basket speed, obtains a still image from the camera assembly, analyzes the image using a machine learning image recognition process to determine a remaining moisture content (RMC) of the load of clothes, and adjusts at least one operating parameter of the washing machine appliance based on the remaining moisture content, e.g., such as ending the drain cycle when a target RMC is reached.
Washing machine with heater and multiple tubs and control method thereof
A washing machine includes a first tub storing water; a first drum provided to be rotatable in the first tub; a first driving motor for rotating the first drum; a second tub storing water; a second drum provided to be rotatable in the second tub; a second driving motor for rotating the second drum; at least one heater for heating water stored in at least one of the first tub and the second tub; and a controller configured to determine whether the at least one heater and the second driving motor are operating at a time to operate the first driving motor, and control operation of the second driving motor to be stopped and control the first driving motor to be operated when the at least one heater and the second driving motor are operating.
Washing apparatus and controlling method thereof
A washing machine including a tub configured to store water; a drum configured to be rotatable in the tub; a motor configured to rotate the drum; heaters configured to heat the water stored in the tub and including a main heater and the sub heater; and a controller configured to control the heaters to stop driving of the sub heater when the current value of the motor exceeds a predetermined reference current value during driving of the motor and the heaters.
WASHING APPARATUS AND CONTROLLING METHOD THEREOF
A method for controlling a washing apparatus including a power supply device is provided. The method includes controlling driving of a motor in a normal washing mode, determining temperature of the power supply device, controlling driving of the motor in an overheating prevention mode for reducing power consumption by the motor, when the temperature of the power supply device is equal to or higher than a first temperature, and repeating the driving in the overheating prevention mode multiple times such that the temperature of the power supply device is below a second temperature lower than the first temperature, wherein the repeating of the driving in the overheating prevention mode multiple times comprises controlling driving of a heater for heating washing water such that power consumption by the heater increases, when a number of times of driving in the overheating prevention mode is greater than a predetermined value.
