A laundry treating appliance for treating laundry according to an automatic cycle of operation includes a chassis defining an interior, a tub provided within the interior, a drum provided within the tub, a motor mounted to the tub and having a drive shaft drivingly coupled to the drum to selectively rotate the drum about the longitudinal axis, a suspension system, and at least one counterweight, wherein the suspension system and the at least one counterweight are configured such that the capacity efficiency of the laundry treating appliance is greater than 45%.

Laundry treating appliance and method of assembly

A laundry appliance for treating a load of laundry according to a cycle of operation comprises a cabinet and a tub assembly housed within the cabinet and comprising a front tub section, a rear tub section and at least one middle tub section provided between the front and rear tub sections.

Laundry treating appliance and tub assembly and method of forming

A method of determining static and dynamic imbalance conditions in a horizontal axis washing machine utilizes a number of dynamic algorithms to automatically determine the total load size, the magnitude of any static load imbalance, and the magnitude of any dynamic load imbalance for any given load in a given washing machine based on power measurements from the washing machine motor obtained in predetermined speed profiles.

Method and apparatus for monitoring load size and load imbalance in washing machine

A dynamic balancer for an automatic washer includes an annular hollow first chamber. A first fluid is held within the first chamber and only partly fills the first chamber. An annular hollow second chamber is disposed adjacent to the first chamber and includes a plurality of objects disposed therein which are movable along the chamber. A second fluid is also held in the second chamber and, in combination with the solid bodies, only partly fills the second chamber. The first fluid in the first chamber produces a first balancing characteristic of the dynamic balancer. The movable objects within the second chamber produce a second balancing characteristic of the dynamic balancer. The second fluid held in the second chamber also produces a third balancing characteristic of the dynamic balancer.

Dynamic balancer for an automatic washer

A method for reducing displacement of a wash basket that is rotatable about an axis of rotation within a washing machine. The method comprises the steps of: mounting a balancing ring to the basket in the plane that is generally perpendicular to a rotation axis of the basket. Another step is supporting the wash basket by a tuned suspension structure to the machine and determining two resonance critical frequencies for two translational degrees of freedom and three resonance rotational frequencies for the three rotational degrees of freedom of the suspension structure. The method also comprises the step of tuning the suspension structure so that the two critical frequencies of translation each occur at or below a critical first motor speed and so that the three rotational frequencies occur at a second speed that is above the critical rotation speed.
