A method of controlling a laundry treatment apparatus, the method including: determining whether bubbles have been generated in a tub of the laundry treatment apparatus in a state in which a second washing apparatus of the laundry treatment apparatus is operated based on a sequence of operations; and based on a determination that bubbles have been generated, reducing bubbles by (i) adding at least one first operation to the sequence of operations or (ii) replacing at least one second operation of the sequence of operations, is disclosed.

Provided are a washing machine and a method for controlling the same. The method for controlling a washing machine includes supplying water to a tub, driving a driving unit to perform tumbling to rotate a drum disposed in the tub, calculating a water level variation in the tub, and displaying freeze state information on a display unit when the calculated water level variation is less than a reference water level variation.

A laundry treating apparatus including a drum holding a washing object, a drive unit rotating the drum, a drive controller, a display unit with an input unit accepting drive unit control orders, and a display communicating treating progress of the washing object. The display unit having a controller with an input data processing unit, an output data processing unit, and a processing unit control program for running the input and output data processing units. The laundry treating apparatus further including a system managing unit enabling the drive controller and display unit to exchange data with the display unit controller, ordering operation of the display unit, and running the processing unit control program, a list storage unit storing a program list the display unit controller runs, and a monitoring unit for initializing the system managing unit if the processing unit control program is not at the list storage unit.

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.

Washing machine appliances and methods for determining load masses are provided. A method includes accelerating rotation of a basket of the washing machine appliance from a first speed to a second speed greater than the first speed and for a predetermined time measured for acceleration of the basket from the first speed; measuring, during the accelerating step, a check speed of the basket at the predetermined time; and measuring, during the accelerating step, an acceleration time for the tub to accelerate from the first speed to the second speed. The method further includes discontinuing acceleration of the basket after the second speed and the predetermined time have reached; and measuring a coast time for coasting of the basket from the check speed to the first speed. The method further includes determining a load mass in the basket based on the check speed, the acceleration time, and the coast time.

Provided is a drum washing machine, including: an outer tank, configured in a shell; a drum, configured in the outer tank and capable of rotating by using a horizontal shaft or an inclination shaft inclining relative to a horizontal direction as a center; a rotating body, configured at a rear part of the drum and having protruding parts in contact with washings on a surface of the rotating body; a driving part, capable of operating in a first drying form and a second driving form, wherein the first driving form refers to a driving form which enables the drum and the rotating body to rotate at different rotating speeds, and the second driving form refers to a driving form which enables the drum and the rotating body to rotate integrally at the same rotating speed; and a control part.

A drainage-dehydration control method of a multi-drum washing machine, the washing machine at least comprising a first washing drum and a second washing drum; the method comprising: before the first washing drum executing drainage or dehydration procedure, judging whether the second washing drum is draining or dehydrating. If yes, the first washing drum continuing executing a washing procedure or a rinse procedure, or suspending executing the drainage or dehydration procedure until the second washing drum finishes dehydration; if no, the first washing drum starting drainage and dehydration. By the above method, the first washing drum and the second washing drum cannot execute the drainage-dehydration procedure at the same time; and during the waiting process of one washing drum, another washing drum continues a washing procedure or a rinse procedure, so as to make the rational use of waiting time and improve the efficiency of washing clothing.

System and method for dispensing product to a washing machine. A chemical dispensing system includes a system controller, machine interface, and pump controller that communicate through serial data buses. The system controller provides a user interface, retrieves washing machine status information from the machine interface, and issues product dispensing commands to the pump controller. The pump controller monitors pump status and dispenses product in response to commands from the system controller. The pump controller: (1) determines pump activation periods based on calibration data stored in a pump controller memory; (2) tracks pump usage and adjusts the activation period to compensate for pump wear as the pump ages; (3) disables the pump if conditions exists that preclude operating the pump; (4) monitors product levels, and (5) reports pump status to the system controller. Integral channels are included in the pump housing to provide stress relief to a squeeze tube.

A washing machine having a breathing lamp set and a method for controlling the same are provided. The breathing lamp set is disposed on an outer wall or inner wall of a housing of the washing machine and is composed of a plurality of breathing lamps. The washing machine further includes a controller, configured to change, according to work process changes of the washing machine, a quantity ratio of lighted breathing lamps to dimmed breathing lamps among the plurality of breathing lamps in the breathing lamp set. The method for controlling the washing machine having the breathing lamp set includes step S1: changing, by the controller, the quantity ratio of lighted breathing lamps to dimmed breathing lamps among the plurality of breathing lamps in the breathing lamp set, so as to discriminately display different work states of the washing machine.

Disclosed is a drum washing machine, including: an outer tank, configured in a shell; a drum, configured in the outer tank and capable of rotating by using a horizontal shaft or an inclination shaft inclining relative to a horizontal direction as a center; a rotating body, configured at a rear part of the drum and having protruding parts in contact with washings on a surface of the rotating body; a driving part, capable of operating in a first drying form and a second driving form, wherein the first driving form refers to a driving form which enables the drum and the rotating body to rotate at different rotating speeds, and the second driving form refers to a driving form which enables the drum and the rotating body to rotate integrally at the same rotating speed; and a control part.
