Benefits of technology
The invention is a laundry treating appliance with a rotating drum for holding laundry. The drum has a cylindrical body with a cover at one end. The cover has a groove with two walls and an adjoining wall. Between these walls is a space where a movable mass is placed. The technical effect of this design is that it provides a more effective and efficient laundry treatment process with improved heat transfer and reduced energy consumption.
Problems solved by technology
If a sufficiently large enough load imbalance is present, the laundry treating appliance may experience undesirable vibrations and movements when the drum is rotated at high speeds during the spin phase.

Embodiment Construction
[0011]FIG. 1 is a schematic view of a laundry treating appliance according to a first embodiment of the invention. The laundry treating appliance may be any appliance which performs a cycle of operation to clean or otherwise treat items placed therein, non-limiting examples of which include a horizontal or vertical axis clothes washer; a combination washing machine and dryer; a tumbling or stationary refreshing / revitalizing machine; an extractor; a non-aqueous washing apparatus; and a revitalizing machine.
[0012]The laundry treating appliance of FIG. 1 is illustrated as a washing machine 10, which may include a structural support system comprising a cabinet 12 which defines a housing within which a laundry holding system resides. The cabinet 12 may be a housing having a chassis and / or a frame, defining an interior that encloses components typically found in a conventional washing machine, such as motors, pumps, fluid lines, controls, sensors, transducers, and the like. Such component...

Abstract
A laundry treating appliance includes a rotatable drum for receiving a laundry load. The rotatable drum includes a cylindrical body with an cylindrical wall, and a cover at one or both ends. The cover has an annular groove formed by a first, second, and third walls. A fourth wall extends from the second wall. A first land is secured to the third wall and a second land is secured to the fourth wall. An adjoining piece has an adjoining wall that is attached to and extends between the first and second lands. A hollow space is bounded by the adjoining wall and the second and third walls. A movable mass is disposed in the space.
Description
BACKGROUND OF THE INVENTION[0001]Laundry treating appliances, such as a washing machine, may implement cycles of operation in which a drum defining a treating chamber for receiving a laundry load is rotated at high speeds, such as a spin or water extraction phase. For example, to extract the water from the laundry load, the drum is typically spun at high speeds. If a sufficiently large enough load imbalance is present, the laundry treating appliance may experience undesirable vibrations and movements when the drum is rotated at high speeds during the spin phase.SUMMARY OF THE INVENTION[0002]In one aspect, the invention relates to a laundry treating appliance that includes a rotatable drum for receiving a laundry load. The rotatable drum includes a cylindrical body with a cylindrical wall about a longitudinal axis, and a cover at one end thereof. The cover has an annular groove formed by a first wall adjacent to the cylindrical wall, a second wall spaced from the first wall, and a th...
