Provided is a method for controlling a laundry treating apparatus. The method includes applying power to the laundry treating apparatus and inputting an installation inspection command through an input part and performing an installation inspection for inspecting whether the laundry treating apparatus is normally installed when the installation inspection command is inputted. A control part determines whether the inputted installation inspection command is an initial installation inspection command, and wherein, when it is determined that the inputted installation inspection command is not the initial installation inspection command, the control part is configured to determine whether the previous installation and inspection has been properly performed according to an unbalance value stored in a memory, and configured to display the determined result a display part.

A laundry treating appliance and method of operating a laundry treating appliance that includes wetting the laundry load in a drum according to a selected cycle of operation and determining a magnitude of imbalance of the wetted laundry load. A controller of the laundry treating appliance is configured to determine a first extraction speed for rotating the drum based on the magnitude of imbalance.

A dynamic imbalance detection system capable of whether a washing machine is in a dynamically imbalanced position by using big data and executing an AI algorithm or a machine learning algorithm in a 5G communications network environment built for IoT. The system includes a washing machine and a server communicating with the washing machine. The washing machine includes a vibration sensor attached to a washing machine cabinet and a controller receiving a vibration signal detected by the vibration sensor during the operation of the washing machine and processing the vibration signal into vibration data. The server receives the vibration data from the controller and trains a machine learning algorithm on a training dataset that is obtained by processing one or more features among a displacement magnitude, a displacement ratio, and a displacement phase, and determines result values of dynamic balance and dynamic imbalance labeled with the one or more features.

A washing machine appliance and methods of operating a washing machine appliance are provided. The washing machine appliance includes a motor and a rotatable basket. The motor is operated to rotate the basket. While operating the motor to rotate the basket, a power consumption and a balance condition of a load of articles in the basket are determined. A size of the load of articles in the basket of the washing machine appliance is determined based on the power consumption and the balance condition. Based on the determined size of the load, one or more operating parameters of the washing machine appliance are selected and an operation of the washing machine appliance is performed according to the one or more selected operating parameters.

Provided are a balance assembly and a household appliance. The balance assembly is applied in the household appliance. The balance assembly includes a balancing ring, a balancer, an identification member and a first detection member. The balancing ring has a chamber defined therein. The balancer is movably arranged in the chamber and includes a rotating member and a driving member. The driving member is connected to the rotating member and configured to drive the rotating member to rotate to drive a movement of the balancer within the chamber. A relative movement between the first detection member and the identification member occurs during the movement of the balancer. The first detection member is to detect a number of times of the identification member passing through the first detection member. The number of times of the identification member passing through the first detection member is related to a position of the balancer.

A washing machine including a drum that is rotatable while accommodated inside a tub; a driving circuit that supplies a driving current to a motor to rotate the drum; a current sensor that senses the driving current; and a controller that controls the drum, the driving circuit, and the current sensor. The controller is enabled to determine whether laundry in the drum contains a waterproof item based on a weight of the laundry and a difference value between a first driving current sensed by the current sensor before a washing cycle and a second driving current sensed by the current sensor after the washing cycle.

A compressor frequency regulation method includes acquiring a first exhaust temperature of a compressor operating at a first operating frequency; determining that the first exhaust temperature is greater than or equal to a first preset temperature; controlling the compressor to perform frequency reduction processing, the frequency reduction processing reducing the first operating frequency to a second operating frequency, such that a second exhaust temperature of the compressor operating at the second operating frequency is less than the first preset temperature; and controlling the compressor to operate at the second operating frequency.
