The terms “including,” “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises a . . . ” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.


Referring to FIG. 1, the laundry appliance 10 is illustrated as a top-load washer. The laundry appliance 10 includes a cabinet 54 having a plurality of panels 58. A door 70 is rotatably coupled with a top panel 66 for selectively sealing and providing access to components disposed within an interior 74 of the cabinet 54.


Referring to FIG. 2, a chassis 14, which is illustrated as a frame, defines the structure of the laundry appliance 10 onto which the plurality of panels 58 are attached to define the cabinet 54. A tub 22 is disposed within the interior 74 of the chassis 14. The tub 22 receives water or other wash liquid for use in a washing cycle of operation. A perforated basket 86 is located within the tub in a conventional manner. An access opening defined in a top panel 66 aligns with a tub opening 82 to provide access to a basket 86. A clothes mover (not shown), which can take the form of a wash plate, impeller, auger, agitator, nutator, etc., can be located in the basket to impart movement to water or laundry within the basket. A motor (not shown) can be carried by the tub and connected to the clothes mover.


A tub suspension system 98 includes suspension rods 46. The suspension rods 46 can be a straight rod connecting the tub 22 to the chassis 14. However, in most cases the suspension rods 46 include a damper, such as a spring, and has a form like a strut. One end of the suspension rods 46 connects to the tub 22 and the other end connects to the chassis 14. As illustrated, there is a suspension rod at each corner of the chassis 14.


The chassis 14 includes brackets 90 coupled to the chassis 14 near a top frame 78 defining a frame opening. The chassis 14 includes four brackets 90, where each bracket 90 is disposed proximate a corresponding corner 94 of the chassis 14.


A profiled rod 26 is carried by the chassis 14 via the brackets 90 and provides a connection point for the suspension rods 46. In this way, the load of the tub 22 is passed to the chassis 14 via the suspension rods 46 and the profiled rod 26.


Referring to FIG. 3, it can be seen that the upper end of the suspension rods 46 terminate in a hook 50 that is hooked over the profiled rod 26 to couple the suspension rods 46 to the chassis 14. The profiled rod 26 can be integrally formed with the bracket 90, or, as illustrated attached to the bracket 90. The bracket 90 can have an opening and the profiled rod 26 can rest on a top surface of the bracket 90. The profiled rod 26 can have a profile portion 29 that extends down through the opening, where it is accessible by the hook 50 of the suspension rods 46. More specifically, the profiled rod 26 includes a chassis engaging first end 27, a chassis engaging second end 28, and the profile portion 29, which has a non-linear shape. The first and second ends 27, 28 overlie the bracket 90, while the profile portion extends down through the opening where it is accessible by the hook 50.


Referring to FIG. 4, the connection between the hook 50 and the profiled rod 26 is illustrated without the surrounding structure for clarity. As can be seen, the hook 50 has a portion of length at least partially rounded in cross-sectional shape. The hook 50 can be made of a suitable metal, but plastics and other materials of sufficient strength are also contemplated. Furthermore, the hook 50 can have a plastic or rubberized coating. Other coatings can also be used to reduce friction between the hook 50 and the profiled rod 26 to enhance smooth operation and reduce potential squeaking and other undesirable noises.


As illustrated, the profiled rod 26 comprises a portion of length at least partially rounded in cross-sectional shape. The non-linear profile portion 29 is a bowed shape or a bowed profile. However, other profiles are contemplated including “U” shaped, “V” shaped, or square-shaped profiles. An attachment aperture 31 can be located on either or both of the first end 27 and the second end 28 to fix the profiled rod 26 to the bracket 90 with a mechanical fastener 32 such as a screw or bolt or by welding or other commonly known fastening techniques. Alternatively, the profiled rod 26 can be attached directly to the chassis 14. The opposing end, that being the end not mechanically attached, may remain free to move. The profiled rod 26 can also be made of a suitable metal, but plastics and other materials of sufficient strength are also contemplated. Plastic or rubberized coatings can also be used to reduce friction between the hook 50 and the profiled rod 26 to enhance smooth operation and reduce potential squeaking and other undesirable noises.


Referring to FIG. 5, a first rotational degree of freedom is illustrated between the hook 50 and the profiled rod 26. Since the hook 50 overlies the profiled rod 26, the hook 50 is free to pivot about an axis coming out of the page in FIG. 5, which pivot motion is shown by the arrow. The hook 50, in a first linear degree of freedom, to some extent, can slide longitudinally along the length of the profiled rod, which longitudinal sliding is resisted by the profiled shape of the profile portion 29 of the profiled rod 26.


Referring to FIG. 6, a second rotational degree of freedom is illustrated between the hook 50 and the profiled rod 26. Since the hook 50 overlies the profiled rod 26, the hook 50 is free to pivot about an axis coming out of the page in FIG. 6, which pivot motion is shown by the arrow. The pivot motion is generally orthogonal to the first rotational degree of freedom. The hook 50 in a second linear degree of freedom, to some extent, can slide left/right as viewed in FIG. 6 to the extent permitted by the shape of the hook 50 and the profile shape of the profile portion 29.


The hook 50 and, thus, the suspension rods 46 can rotate, to the extent permitted by the shape of the hook 50 and profile portion 29, about the longitudinal axis of the suspension rod, to provide another limited degree of freedom. However, the primary degrees of freedom are the first and second rotational degrees of freedom.


While the profiled rod 26 is illustrated as physically separate from and mechanically affixed to the bracket 90, the profiled rod 26 can be integrally formed with the top frame 78 and the bowed profile portion 29 extends below and is accessible from beneath the top frame 78. According to another aspect, the second end 28 free end is at least partially received within a retaining feature formed within the top frame 78.


To assemble the suspension system, the profiled rods 26 are attached to the chassis 14 with the bowed profile portion 29 of the profiled rod 26 protruding below the top frame 78 and into the interior 74 of the cabinet. The suspension rods 46 can be attached to the corresponding profiled rod 26 via the suspension rod hook 50 from underneath the top frame 78. Each suspension rod 46 extends from the lower portion 106 (FIG. 2) of the tub 22, to couple with the profiled rods 26.


The suspension rods 46, when so attached to the profiled rod 26 via the hook 50 is configured to pivot about the two primary degrees of rotational freedom. When assembled, each of the suspension rods 46 engage with the bowed profile portion 29 of the profiled rod 26 to carry the load of the tub 22. In one embodiment, the hook 50 and the profiled rod 26 both have at least a partially rounded cross-sectional shape allowing for movement in two degrees of freedom relative to one another with degrees of freedom indicated by arced arrows. In operation, the suspension rods 46 remain engaged until the hook 50 is manually disengaged from the profiled rod 26. Any load imparted from the basket 86 during a wash cycle of operation to the suspension rods 46, will be transferred to the chassis. The tub 22 is free to “swing” in the two rotational degrees of freedom.


Use of the present device provides for a variety of advantages including ease of assembly and simplicity with minimal parts. For example, the suspension rods 46 can easily be installed when the hook 50 is within a rotational range of about 180° relative to the profiled rod 26. This produces a greater margin or tolerance for workers assembling the laundry appliance 10. Additional benefits or advantages of using this device may also be realized and/or achieved.


While the suspension system has been illustrated in the environment of a top-loader or vertical axis clothes washer, the same suspension system can be used in a front-loader or horizontal-axis washing clothes washing machine. Front-loading or horizontal-axis clothes washers have the same or similar chassis and tub configuration on which the suspension system can be used.
