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.

Disclosed are a method and apparatus for washing machine dehydration, and a washing machine. The method includes: step 1, detecting a current eccentricity value to serve as a first eccentricity value, and determining a first dehydration rotational speed value corresponding to the first eccentricity value; step 2, performing a corresponding dehydration operation; step 3, detecting another current eccentricity value to serve as a second eccentricity value, and determining a second dehydration rotational speed value corresponding to the second eccentricity value; step 4, if the second eccentricity value is smaller than the first eccentricity value, performing a corresponding dehydration operation, assigning the value of the second eccentricity value to the first eccentricity value and then performing the step 3; and step 5, if the second eccentricity value is greater than or equal to the first eccentricity value, performing a leveling operation, and then performing the step 3.

A laundry apparatus includes a tub, a drum, a control unit, a motor, and a dynamic balancing assembly. The drum is positioned within a fluid containment envelope of the tub and rotatable relative to the tub about a primary rotation axis. The motor is coupled to the tub and operatively coupled to the drum to cause rotation of the drum. The dynamic balancing assembly includes an orbital balancing passage arranged concentrically around the motor, a first counterweight device, and a second counterweight device. The first and second counterweight devices are positioned within the orbital balancing passage and are responsive to the control unit to move the first and second counterweight devices along the orbital balancing passage to adjust an angular position of the first and second counterweight devices. A cross-sectional plane passes through the dynamic balancing assembly, the motor, and the fluid containment envelope of the tub.

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 washing machine appliance and a method of preventing and mitigating out-of-balance conditions during a spin cycle are provided. In one example aspect, liquid is flowed into the tub and articles within a basket rotatably mounted in a tub of the washing machine appliance are agitated for a first time period. The movement of the tub during the first time period is measured and a trend line is calculated based on the movement of the tub over the first time period. A time remaining is calculated based at least in part on the trend line. If the time remaining is less than a time remaining threshold, and if the determined time remaining is less than the time remaining threshold, the articles within the basket are agitated by an extended agitation time period in which the washing machine appliance attempts to more evenly distribute the articles prior to a spin 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.
