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 washing machine and a method of controlling the same are disclosed. The amount of laundry that is introduced into the washing machine is measured using gravity and inertia applied during the operation of the motor, whereby it is possible to precisely calculate the amount of laundry and to minimize the effects of the initial position of the laundry and the movement of the laundry. In addition, the current value of the motor that is operated is used to measure the amount of laundry without a sensor. Furthermore, the amount of laundry is measured at the rotational speed of the motor at which the laundry clings to the drum, whereby it is possible to minimize an error due to the movement of the laundry to thus improve accuracy. Moreover, it is possible to determine the amount of laundry within a short time. Consequently, it is easy to commence the spin-drying operation, thereby reducing washing time and saving energy.

A washing machine and method for operating a washing machine having a suds container for holding washing liquid, a non-ribbed drum provided with stamped portions rotatably mounted in the suds container for holding laundry, a motor for driving the drum, and a control device. During rotation of the drum in a subcritical rotational speed range, the method includes sampling a variable related to the drum or the motor over a predetermined period of time to determine time signals of the variable, executing a frequency analysis of the time signal of the variable to determine frequency components of the variable in a predetermined frequency range, summing the frequency components at predetermined frequencies of the predetermined frequency range, and detecting, depending on the sum of the summed up frequency components, whether a loading situation where laundry is sliding in the drum is present.

The system body (30) receives the source water (16) from the water source (14). The ozone generator (38) is configured to generate ozone. The ozone generator (38) is coupled the system body (30). The sensor assembly (21) is also coupled to the system body (30). The sensor assembly (21) is configured to sense at least one ambient environmental condition and generate at least one electronic data signal based on the sensed at least one ambient environmental condition. The controller (46) receives the at least one electronic data signal from the sensor assembly (21) and regulates a level of ozone that is generated by the ozone generator (38) based at least in part on the at least one electronic data signal.

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.

A washing machine and method for operating a washing machine having a suds container for holding washing liquid, a non-ribbed drum rotatably mounted in the suds container for holding laundry, a motor for driving the drum, and an open or closed loop control device, wherein the method has a step for rearranging the laundry in the drum. The drum is caused to execute a right-left motion by means of the motor so as to cause a rocking motion of the laundry at a rocking frequency, the predetermined rocking amplitude of which is adjusted such that a laundry fall is implemented in which the laundry falls from a first region of the drum into a second region of the drum.

A method for operating a dryer appliance includes, after drying articles within the dryer appliance, receiving data corresponding to an activation signal for an extended tumble from a remote user device, tracking a number of cycles for which the extended tumble is not a default setting for the dryer appliance, and automatically adjusting the extended tumble to the default setting for the dryer appliance or transmitting data corresponding to an extended tumble alert based on the tracked number of cycles.

A feed device, planar washing machine and method. The feed device (15) comprises roll arrangement (21) provided with support rolls (16, 17) and an alignment roll (18). An endless belt (13) is arranged around the rolls. The alignment roll can be moved (C) in order to guide the feed belt to move into desired direction when it is moved laterally.

A washing machine and method for operating a washing machine having a suds container and a non-ribbed drum. During rotation of the drum in a subcritical rotational speed range, the method includes determining an average value, a minimum, and a maximum of an oscillation of a physical variable relating to the drum or the motor, forming an overall average value from the determined average values, subtracting the overall average value formed from the corresponding minimum determined per oscillation and the corresponding maximum determined per oscillation to calculate a maximum value and a minimum value per oscillation, respectively. In each case an amount is formed from the respective calculated maximum value and an amount is formed from the respective calculated minimum value, a standard deviation from the amounts is determined, and a loading situation where laundry is rolling in the drum is determined based on the determined standard deviation.

A pair of laundry appliances includes a washing machine appliance and a dryer appliance matched with the washing machine appliance. A method of operating the pair of laundry appliances includes receiving, from a user via a remote user interface device, an access request for the washing machine appliance and reserving the washing machine appliance and the dryer appliance for the user. The method also includes unlocking the reserved washing machine appliance via the remote user interface device and activating the reserved washing machine appliance after unlocking the reserved washing machine appliance. The method further includes unlocking the reserved dryer appliance via the remote user interface device and activating the reserved dryer appliance after unlocking the reserved dryer appliance.
