Patent number: 11332867Abstract: A washing machine appliance includes a wash basket rotatably mounted within a wash tub and 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 first and second displacement amplitudes of the wash tub. Bearing forces at the front and rear bearings are obtained based on the basket speed and the displacement amplitudes. The determined bearing force at the front bearing is compared to a front limit. The determined bearing force at the rear bearing is compared to a rear limit. If the determined bearing force value at either of the front bearing or the rear bearing is greater than or equal to the respective limit, an operating parameter of the washing machine appliance is adjusted to limit bearing forces resulting from out-of-balance loads.Type: GrantFiled: February 5, 2019Date of Patent: May 17, 2022Assignee: Haier US Appliance Solutions, Inc.Inventor: Paul Owen Davis

Patent number: 11021825Abstract: A washing machine appliance configured to detect a location of an imbalanced load is provided. The washing machine appliance utilizes the displacement or a component of the displacement of a tub of the washing machine appliance to determine the location of an out-of-balance load. In particular, the washing machine compares the displacement or component of the displacement of the tub at a first point with the displacement of the tub at a second point that is positioned forward of the first point. By comparing the displacement or components of the displacement of the tub at these two points, the location of the imbalanced load may be determined. Methods for determining imbalanced loads are also provided.Type: GrantFiled: April 11, 2018Date of Patent: June 1, 2021Assignee: Haier US Appliance Solutions, Inc.Inventors: Gregory Allen Dedow, Paul Owen Davis

Patent number: 10753030Abstract: 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.
