摘要： A washing machine and a steam washing method. In order to enable the washing machine to meet a user's demand for refined washing and to achieve the object of reducing washing machine costs and energy consumption, the steam washing method includes: receiving an initial washing program of the washing machine; determining whether a steam washing instruction is received; and if not, performing a corresponding initial washing operation according to the initial washing program, and if so, configuring at least one steam washing program based on the initial washing program, where the washing machine can perform the corresponding steam washing operation according to the steam washing program. The method heats a minimum amount of water each time to generate steam, and determines whether a second heating is performed to generate steam based on the washing effect, so massive heating is avoided if much steam is unnecessary, thus maximizing energy savings.

摘要： Disclosed herein are a washing machine and a control method thereof. The control method effectively transmits high-concentration wash liquid to laundry, while minimizing the amount of water used, through washing using bubbles, and maximizes the increase in volume of the wash liquid rubbed on the inner circumferential surface of the drum using the generation of bubbles and the rotation of the drum to raise the water level of the wash liquid without additional water.

摘要： A method of operating a washing machine appliance is provided. The washing machine appliance includes a rotatable basket and a motor configured to drive the rotatable basket. The method includes sensing an attribute of articles in the basket. The method also includes determining a pause duration for an agitation operation based at least in part on the sensed attribute of the articles in the basket. The method further includes performing the agitation operation for a period of time. The agitation operation includes activating a motor of the washing machine appliance to agitate the articles within the basket for an agitation duration and deactivating the motor of the washing machine appliance for the pause duration. The period of time is equal to the sum of the agitation duration and the pause duration.

摘要： A washing machine appliance includes a wash tub defining a wash chamber, a wash basket rotatably mounted within the wash tub, and a motor operably coupled to the wash basket for selectively rotating the wash basket. A controller is configured for accelerating the wash basket to a predetermined speed during an acceleration period and maintaining that speed during a steady state period. The controller further determines a power drop from the maximum power required to accelerate the wash basket to the power required to maintain the predetermined speed, and the dry load weight is calculated using this power drop and a transfer function.

摘要： A laundry treating apparatus may include a main body, a door, a driver, a water supplier, a drain port, a sensor, and a controller. The sensor includes a dust sensor for measuring a dust concentration inside a washing tub, a gas sensor for measuring gas components inside the washing tub, a turbidity sensor for detecting a water quality of the washing water contained in the washing tub, a conductivity sensor, and a spectroscopic sensor. The controller controls the driver, the water supplier, the drain port, and the sensor, and calculates an expected washing time based on data measured through the sensor and the driver.
