Washing machine with tilt-out laundry assembly
An apparatus and method for an improved washing machine having a tilt-out laundry assembly. The tilt-out action is achieved by a tiltable joint between the side of the laundry assembly and front standing struts. The tiltable joint permits a laundry assembly to rotate about the front standing struts once rear struts are removed from the rear side of the laundry assembly. In use, the service person removes the rear struts, tilts the laundry assembly about the front standing struts, and then removes the laundry assembly from the cabinet.

Top loading washing machines have a laundry assembly that may be occasionally serviced. During service, the laundry assembly which is usually suspended within the washing machine is removed. Typically, the suspended laundry assembly is removed by a service person who must lift the entire suspended laundry assembly upward vertically approximately 4 inches to clear all of the other components in the washing machine and then, while the laundry assembly is still elevated, the operator must pull it forward, maneuver it past the cabinet brackets, and out of the cabinet and then placed upon the floor. This servicing is awkward because the person must lean over the top of the machine with his/her feet off of the base frame to insure that no damage occurs to the base frame. In addition, the laundry assembly is 77 pounds in weight and difficult to move without proper leveraging. In addition, the prior art position may be alleviated upon using ergonomic industrial design considerations.
Therefore, a primary objective of the present invention is the provision of an improved washing machine that facilitates ergonomic removal of suspended laundry assemblies. A further objective of the present invention is the provision of a tilting feature and method of using same which moves the laundry assembly from an upright operate position to a tilt remove position to facilitate removal of the laundry assembly without the risk of damage to the washing machine from incorrect removal, accidental droppings, or the service person accidentally stepping upon the base frame.
A further objective of the present invention is the provision of a ball and socket joint between the laundry assembly and struts supporting the laundry assembly to provide for proper tilting of the laundry assembly.
A further objective of the present invention is the provision of an improved washing machine with tilt-out laundry assembly which is economical to manufacture, durable in use and efficient in operation.
BRIEF SUMMARY OF THE INVENTIONThe foregoing objectives may be achieved by an improved washing machine with a cabinet with a laundry assembly suspended within. The laundry assembly is suspended by front standing struts having an upper end attached to the laundry assembly and a lower end attached to a base of the cabinet. The laundry assembly is also suspended by removable rear struts having one end attached to the cabinet and a second end attached to the rear side of the laundry assembly. A tiltable joint is provided between the front standing struts upper end and the side of the laundry assembly that permits the laundry assembly to move between an upright position to a tilt remove position.
According to another feature of the present invention the tiltable joint is a ball and socket joint. This ball and socket joint has a recess in the socket that permits the laundry assembly to move from the upright position to the tilt position. The recess prevents a rod of the front standing strut from interfering with the rotation of the ball within the socket.
According to another feature of the present invention a corresponding recess is placed within the support molding of the front side of the laundry assembly and a recess provided in a cushion that engages the front standing strut. These additional recesses also prevent the rod from interfering with the rotation of the ball within the socket and permit the laundry assembly to tilt from an operational position to a remove position. The foregoing objectives may also be achieved by a method of servicing an improved washing machine with a tilt-out laundry assembly as described including removing the rear struts from the rear side of the laundry assembly, tilting the laundry assembly about the front standing struts, and removing the laundry assembly from the cabinet.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to
The present invention is directed towards the tilt-out laundry assembly 24. The laundry assembly 24 has a front side 26 and a rear side 28. Upon the front side 20 are a pair of front arms 30 and upon the rear side 28 are a pair of rear arms 32. The laundry assembly 24 is suspended within the cabinet 12 by front standing struts 34 and removable rear struts 36. The front standing struts 34 have an upper end 38 operably attached to the front arm 30 on the front side 26 of the laundry assembly 24. In addition, the front standing struts 34 have a lower end 40 that is attached to the base 14. The front standing strut 34 has a cylinder 42 with an extensible rod assembly 44 connected thereto. The cylinder 42 may have a spring or compressible fluid which provides dampening to the rod assembly 44 in response to vibrations which may come from the laundry assembly 24.
The removable rear struts 36 are operably attached to the cabinet 12 by bracket 46 and removably attached to the rear arms 32 by member 48. The removable rear struts 36 typically use a continuous rod.
As seen between
As seen in
The socket 60 has a recess 66 that permits rotation of the laundry assembly 24 beyond a point where the rod 50 would strike a sidewall of the socket 60.
Attached and surrounding the socket is a cushion 68 which dampens vibrations from the laundry assembly 24 when the laundry assembly 24 is in use. The cushion 68 has a recess 70 in alignment with the socket recess 66 to permit rotation of the laundry assembly 24 past where the cushion would interfere with pivotal movement.
The front arm 30 has support molding 72 that provides strength to the front arms 30. The front arms 30 has a recess 74 in the support molding 72 to prevent travel of the rod 44 of the front standing strut 34 and permit the laundry assembly 24 to move from the upright position to the tilt position. Thus, the socket recess 66, the cushion recess 70, and the support molding recess 74 all work together to permit the laundry assembly 24 to move from the upright position to the tilt position.
As further seen in
The angle of movement from the upright position to the tilt position should be between 45 to 90° to provide the service person with enough tilt to easily remove the laundry assembly. In the preferred embodiment the angle of movement from the tilt position is between 75 to 90°. Most often, the service person will rotate the laundry assembly 24 to a right angle position before lifting and removing the laundry assembly 24.
In an alternative embodiment, the invention may be employed in a horizontal axis washer. In this case, the axis of the laundry assembly 24 is horizontal in the upright operate position.
In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, these are used in a generic and descriptive sense only and not for purposes of limitation. Changes in the form and the proportion of parts as well as in the substitution of equivalents are contemplated as circumstances may suggest or render expedient without departing from the spirit or scope of the invention as further defined in the following claims.
