Washing machine

A washing machine includes a cabinet; a tub disposed in the inside of the cabinet; at least one suspension apparatus configured to reduce vibrations of the tub, and to connect the tub to the cabinet such that the tub is supported on the cabinet; and a position guide apparatus having one end connected to the at least one suspension apparatus, and the other end connected to the tub, and configured to limit a movement range in horizontal direction of the tub.

Washing machine appliances and methods of using counterweight amplitude to limit basket speed

A washing machine appliance, including one or more methods of operation, is provided herein. The washing machine appliance includes a wash basket rotatably mounted within a wash tub and being supported by a front bearing and a rear bearing. A method of operating the washing machine appliance includes rotating the wash basket within the wash tub at a basket speed and obtaining a front displacement amplitude, a rear displacement amplitude, and a wobble angle of the wash tub. Based at least in part on these measured values, front and rear bearing force amplitude thresholds and virtual bearing force values are calculated and compared. If the virtual bearing force value of either the front or rear bearing exceeds the respective bearing force amplitude threshold, an operating parameter of the washing machine appliance is adjusted to limit bearing forces resulting from out-of-balance loads.

Laundry washing machine with dynamic damping force optimization

A laundry washing machine and method implement dynamic damping force optimization during a wash cycle to optimize a force-generating operation such as a spin operation performed during the wash cycle. The dynamic damping force optimization may utilize inputs from a suspension force sensor in combination with an accelerometer to dynamically determine a damping capability for a suspension of a laundry washing machine such that damping in the suspension system may be maintained within the damping capability of the suspension system to balance operation performance against the generation of undesirable forces and vibrations.

FLANGE SHAFT DEVICE AND WASHING MACHINE

A flanged-shaft apparatus (1) is configured for rotatably supporting a drum (4) in a washing machine having such a flanged-shaft apparatus (1). The flanged-shaft apparatus (1) has a connecting flange (2) configured to be arranged against a drum base (41) of the drum (4) and attached to the drum (4), and a drive shaft (3) arranged in the center of the connecting flange (2) and connected thereto for connection to a drive motor. The connecting flange (2) has a main element (21) formed from a steel sheet and a supporting element (22) formed from a further steel sheet. The main element (21) and the supporting element (22) are arranged one on top of the other along a longitudinal axis (L) of the drive shaft (3).

Laundry treating appliance with liquid dam

A laundry treating appliance is configured to treat laundry according to a cycle of operation. The laundry treating appliance comprises a chassis that defines an interior and has a front and rear with an access opening located in the front. A tub statically mounted to the chassis and defines a liquid chamber located within the interior and has at least one suspension opening. An exoskeleton is located within the liquid chamber and has a front support, a rear support, and stringers extending longitudinally to form a skeletal frame defining a frame interior. A rotatable drum is located within the frame interior. A suspension system is located within the interior and has at least one suspension component extending into the liquid chamber through the suspension opening and is operably coupled to the exoskeleton. A liquid dam retards liquid flow from the liquid chamber to the interior through the suspension opening.

WASHING MACHINE

A washing machine belongs to the field of washing machines and comprises a water collection structure for stopping water drained from an inner tub out of overflowing and a drainage structure for draining the water in the water collection structure, the inner tub comprises a tub body and a tub bottom arranged at a lower part of the tub body, the water collection structure is located outside the tub bottom of the inner tub. The spacing distance between the tub body and a case body of washing machine is greater by locating the water collection structure outside the tub bottom of the inner tub, so that greater-extent capacity expansion may be realized, and the washing machine is reasonable in design, simple in structure and low in cost.

LAUNDRY TREATING APPLIANCE

A fabric treating appliance for treating an article according to a cycle of operation includes a chassis defining an interior with a tub provided within the interior, the tub at least partially defining a liquid chamber. A drum is provided within the liquid chamber to at least partially define a treating chamber. The drum has a peripheral wall terminating in a front edge and a rear edge, with the front edge defining a front opening. An exoskeleton is provided within the liquid chamber coupling the drum to the chassis.

DAMPING DEVICE FOR A WASHING MACHINE, AND WASHING MACHINE

A damping device for a washing machine and a washing machine are provided. The damping device for a washing machine comprises an upper boom, a damping spring mechanism and a lower boom, wherein an upper end of the upper boom is installed on a cabinet of the washing machine, a lower end of the lower boom is installed on an outer tub of the washing machine, the damping spring mechanism is installed between the upper boom and the lower boom, and the upper boom and/or the lower boom are/is elastically stretched under the drive of the damping spring mechanism.

A washing machine appliance, including one or more methods of operation, is provided herein. The washing machine appliance includes a wash basket rotatably mounted within a wash tub and being supported by a front bearing and a rear bearing. A method of operating the washing machine appliance includes rotating the wash basket within the wash tub at a basket speed and obtaining a front displacement amplitude, a rear displacement amplitude, and a wobble angle of the wash tub. Based at least in part on these measured values, front and rear bearing force amplitude thresholds and virtual bearing force values are calculated and compared. If the virtual bearing force value of either the front or rear bearing exceeds the respective bearing force amplitude threshold, an operating parameter of the washing machine appliance is adjusted to limit bearing forces resulting from out-of-balance loads.

Washing machine

A washing machine includes a plurality of suspension units through which a tub is supported by a cabinet, and a stabilizer unit mounted to the tub. When horizontal vibration displacement of the tub occurs by unbalance mass during washing/dehydration processes, the washing machine limits tub displacement according to the attenuation effect caused by torsional force and bending force of the stabilizer unit, resulting in reduction of excessive vibration.
