Description

BACKGROUND OF THE DISCLOSURE

[0001] The present disclosure generally relates to a dishwasher, and more specifically, to a dishwasher door balance assembly. Dishes may remain moist at the end of a wash cycle. Allowing hot air present within the dishwasher after a wash cycle to rise by convection out of the dishwasher provides an energy efficient method to dry dishes after a wash cycle. Accordingly, a dishwasher door balance assembly is provided to maintain a dishwasher door at a predetermined angle from an opening of the dishwasher to facilitate the flow of hot air out of the dishwasher. Also, the dishwasher door balance assembly may be configured to facilitate a controlled opening, as a user of the dishwasher opens the dishwasher door.SUMMARY OF THE DISCLOSURE

[0002] According to one aspect of the present disclosure, a dishwasher includes a dish treating tub, a bottom railing, and a dishwasher door operably coupled to the dish treating tub. The dishwasher door is configured to pivot between a closed position, a drying position, and an open position. The dishwasher includes a dishwasher door balance assembly. The dishwasher door balance assembly includes a hinge bracket coupled with the dish treating tub, a hinge formed by the hinge bracket, and a rotation arm including an offset portion. The rotation arm is coupled with the dishwasher door and rotatably coupled with the hinge. The offset portion of the rotation arm is vertically offset from a horizontal axis of the hinge when the dishwasher door is in the closed position. The offset portion forms a connection feature. The dishwasher door balance assembly further includes a first biasing element coupled with the bottom railing and the connection feature.

[0003] According to another aspect of the present disclosure, a dishwasher includes a dish treating tub and a dishwasher door operably coupled to the dish treating tub configured to pivot between a closed position, a drying position, and an open position. The dishwasher includes a dishwasher door balance assembly. The dishwasher door balance assembly includes a hinge bracket coupled with the dish treating tub, a hinge formed by the hinge bracket, and a rotation arm including an offset portion. The rotation arm is coupled with the dishwasher door and rotatably coupled with the hinge. The offset portion of the rotation arm is vertically offset from a horizontal axis extending from the hinge when the dishwasher door is in the closed position. The dishwasher door balance assembly further includes a first biasing element coupled with the offset portion of the rotation arm.

[0004] According to yet another aspect of the present disclosure, a dishwasher includes a dish treating tub, a bottom railing, a biasing mount, a dishwasher door operably coupled to the dish treating tub and configured to pivot between a closed position, a drying position, and an open position, and a dishwasher door balance assembly. The dishwasher door balance assembly includes a hinge bracket coupled with the dish treating tub, a hinge formed by the hinge bracket, and a rotation arm including an offset portion. The rotation arm is coupled with the dishwasher door and rotatably coupled with the hinge. The offset portion of the rotation arm is vertically offset from a horizontal axis of the hinge when the dishwasher door is in the closed position, and forms a first member, wherein the first member forms a hook. The dishwasher door balance assembly further includes a first biasing element coupled with the bottom railing and the first member and a second biasing element coupled with a biasing mount and the first member.

[0005] The present assembly provides for a variety of advantages. For example, a dishwasher door balance assembly coupled with a dishwasher provides an energy efficient and automatic method to dry dishware and utensils after a wash cycle of the dishwasher. Specifically, the dishwasher door balance assembly functions to automatically open and then balance a dishwasher door in a drying position relative to an opening of the dishwasher. Consequently, steam and hot air generated by the dishwasher during a wash cycle circulates through a washing chamber of the dishwasher, drying the dishware and utensils, before exiting at a controlled rate through a top portion of the opening of the dishwasher. As such, energy is conserved by utilizing the steam and hot air generated by the wash cycle to dry the dishware and utensils, as opposed to expending additional energy to dry the dishware and utensils. Further, the present assembly may allow for a controlled passage of steam and hot air out of the opening of the dishwasher. Specifically, only the top portion of the opening may be uncovered at the drying position. As such, the majority of steam and hot air within the washing chamber may pass through this partial opening. Accordingly, when the user transitions the dishwasher door to the open position, there may be only trace amounts of steam and hot air present still within the washing chamber. This may prevent the steam and hot air from contacting the user when the user transitions the dishwasher door to the open position. Additional benefits and advantages may be realized and / or achieved.

[0006] These and other features, advantages, and objects of the present disclosure will be further understood and appreciated by those skilled in the art by reference to the following specification, claims, and appended drawings.BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Referring to FIGS. 1-12C, reference numeral 10 generally designates a dishwashing appliance or a dishwasher 10. The dishwasher 10 includes a dish treating tub 12. A dishwasher door 14 is operably coupled to the dish treating tub 12 and is configured to pivot between a closed position C, a drying position D, and an open position O. The dishwasher 10 includes a dishwasher door balance assembly 16 that includes a hinge bracket 18 coupled with the dish treating tub 12, a hinge 20 formed by the hinge bracket 18, and a rotation arm 22. The rotation arm 22 is coupled with the dishwasher door 14 and is rotatably coupled with the hinge 20. An offset portion 24 of the rotation arm 22 is vertically offset from a horizontal axis 26 of the hinge 20 when the dishwasher door 14 is in the closed position C. The offset portion 24 may form a first member 28 and a second member 30. The dishwasher door balance assembly 16 further includes a first biasing element 32 coupled with a first bottom railing 34 and the second member 30. The first biasing element 32 may be configured to provide a force urging the dishwasher door 14 to pivot from the closed position C to the drying position D and to resist the pivoting of the dishwasher door 14 from the drying position D to the open position O.

[0031] Referring now to FIG. 2, the illustrated dish treating tub 12 is formed of a top wall 36 opposing a bottom wall 38 that both extend between a first side wall 40 that opposes a second side wall 42. Together, the top wall 36, the bottom wall 38, the first side wall 40, and the second side wall 42 define an opening 44 to a washing chamber 46 that is formed by the top wall 36, the bottom wall 38, the first side wall 40, the second side wall 42, and a rear wall 48 provided opposite the opening 44. A door frame 50 is attached to and circumscribes the perimeter of the opening 44 and the dishwasher door 14 is operably coupled with the door frame 50 to cover the opening 44. A latch 52 is provided by the door frame 50 to interact with a locking mechanism 54 provided by the dishwasher door 14. The dishwasher door 14 is operable between the closed position C, the drying position D, and the open position O.

[0032] Referring now to FIGS. 3A-3C, the dishwasher door 14 is operably coupled with the door frame 50 to cover the opening 44 and pivots at a bottom portion 56 of the dishwasher door 14, relative to the opening 44 between the closed position C, the drying position D, and an open position O. A top portion 58 of the dishwasher door 14 travels along an arc as the bottom portion 56 pivots between the closed position C, the drying position D, and the open position O. As such, in the drying position D, the dishwasher door 14 may be pivoted such that only a top portion of the opening 44 is uncovered.

[0033] The dishwasher door 14 is illustrated in the closed position in FIG. 3A. In the closed position C, the top portion 58 of the dishwasher door 14 is substantially flush with the door frame 50, covering substantially the entirety of the opening 44. As such, steam and hot air produced during a wash cycle of the dishwasher 10 is unable to pass through the opening 44 and is maintained within the washing chamber 46. The dishwasher door 14 is maintained substantially flush with the opening 44 via the interaction between the latch 52 and the locking mechanism 54. A user of the dishwasher 10 may interact with the locking mechanism 54 to disengage the locking mechanism 54 from the latch 52. Once the locking mechanism 54 is disengaged, the force of gravity and a force provided by the dishwasher door balance assembly 16 may urge the dishwasher door 14 to begin pivoting counterclockwise from the closed position C to the drying position D.

[0034] The dishwasher door 14 is illustrated in the drying position D in FIG. 3B. In the drying position D, the top portion 58 of the dishwasher door 14 is spaced apart from the opening 44 to allow for at least a portion of the steam and hot air contained within the washing chamber 46 to pass through the opening 44. Specifically, convection forces drive the steam and hot air upwards towards the portion of the opening 44 uncovered via the pivoting of the bottom portion 56 and the resulting traversal of the top portion 58 from the opening 44. As the steam and hot air rises, dishware and other utensils contained within the washing chamber 46 may be heated and resultingly dried.

[0035] In the drying position D, an angle A, extending between the top portion 58 of the dishwasher door 14 and the opening 44, may be between about 3 degrees and about 15 degrees. In the drying position D, the angle A may be greater than any angle distal to the top portion 58 that extends between the dishwasher door 14 and the opening 44. As such, the opening 44 is uncovered primarily at the region of the opening 44 that is proximate to the top portion 58 of the dishwasher door 14. This configuration facilitates the upwards movement of steam and hot air from the bottom portion of the washing chamber 46 as a function of the pressure difference between the interior of the washing chamber 46 and the external atmosphere. Accordingly, the hot air and steam may contact a substantial majority of the dishware and utensils contained in the washing chamber 46.

[0036] As shown in FIG. 3B, the top portion 58 of the dishwasher door 14 may be maintained in the drying position D via a force produced by the dishwasher door balance assembly 16. The dishwasher door 14 may be maintained in the drying position D until an external force acts upon the dishwasher door 14 urging the dishwasher door 14 to pivot to the open position O.

[0037] The dishwasher door 14 is illustrated in the open position O in FIG. 3C. In the open position O, an angle B, extending between the top portion 58 of the dishwasher door 14 and the opening 44 may be between about 90 degrees and about 75 degrees. Moreover, in the open position O, the dishwasher door 14 may be substantially perpendicular to the opening 44 and the door frame 50. As such, in the open position O, the opening 44 is substantially uncovered. The user may then access the washing chamber 46 and the dishware and utensils therein. Further, at the time the dishwasher door 14 reaches the open position O, the steam and hot air present within the washing chamber 46 may have previously escaped the washing chamber 46 when the dishwasher door 14 was in the drying position D. Consequently, a second volume of steam and hot air present within the washing chamber 46 when the dishwasher door 14 reaches the open position O, may be less than a first volume of steam and hot air present within the washing chamber 46 when the dishwasher door 14 was in and / or had just begun transitioning from the drying position D to the open position O.

[0038] From the open position O, the bottom portion 56 of the dishwasher door 14 pivots clockwise to return the dishwasher door 14 to the drying position D. From the drying position D, an external force may be necessary to overcome the force exerted by dishwasher door balance assembly 16 to pivot the bottom portion 56 clockwise and place the dishwasher door 14 within the closed position C.

[0039] Referring now to FIGS. 4 and 5, a first support 62 may be attached to a lower portion 70 of the first side wall 40 and positioned towards the dishwasher door 14. A second support 66 may be attached to a lower portion 72 of the second side wall 42 and positioned towards the dishwasher door 14 as shown in FIG. 5. Both the first support 62 and the second support 66 vertically extend from the lower portion 70 of the first side wall 40 and the lower portion 72 of the second side wall 42 respectively, towards the surface the dishwasher 10 is supported upon.

[0040] With continued reference to FIGS. 4 and 5, a first leveling element 74 is adjustably coupled with and vertically extends from the first support 62 towards the surface. A second leveling element 76 is adjustably coupled with and vertically extends from the second support 66 towards the surface as shown in FIG. 5. The dish treating tub 12 may at least partially be supported upon the surface via the first leveling element 74 and the second leveling element 76. Further, the vertical position of the dish treating tub 12, and accordingly the dishwasher 10, may at least partially be a function of the height of the first leveling element 74 and the second leveling element 76. The height of the first leveling element 74 is adjustable such that the vertical position of the dishwasher 10 may be adjusted. Likewise, the height of the second leveling element 76 is adjustable, such that the vertical position of the dishwasher 10 may be adjusted.

[0041] With continued reference to FIGS. 4 and 5, a first bottom railing 34 may extend between the first support 62 and a rear portion 78 of the bottom wall 38. The first bottom railing 34 may extend substantially parallel to the bottom wall 38 from the first support 62 along the surface to provide further support for the dishwasher 10. The first bottom railing 34 may curl upwards towards the rear portion 78 of the bottom wall 38 and may be fixed to the portion of the bottom wall 38 proximate the first side wall 40. As shown in FIG. 5, a second bottom railing 80 may extend between the second support 66 and the rear portion 78 of the bottom wall 38. The second bottom railing 80 may extend substantially parallel to the bottom wall 38 from the second support 66 along the surface to provide further support for the dishwasher 10. The second bottom railing 80 may curl upwards towards the rear portion 78 of the bottom wall 38 and may be fixed to the portion of the bottom wall 38 proximate the second side wall 42. Together the first bottom railing 34 and the second bottom railing 80 provide additional support for the dishwasher 10 against the surface.

[0042] Referring now to FIG. 6, the dishwasher door balance assembly 16 may be positioned adjacent to the first side wall 40 of the dish treating tub 12. Alternatively, the dishwasher door balance assembly 16 may be positioned adjacent to the second side wall 42 of the dish treating tub 12 as shown in FIG. 5. Also, a first dishwasher door balance assembly may be positioned adjacent to the first side wall 40 and a second dishwasher door balance assembly may be positioned adjacent to the second side wall 42. In such a configuration, the first dishwasher door balance assembly and the second dishwasher door balance assembly may be substantially identical in composition and in operation.

[0043] Generally, the dishwasher door balance assembly 16 is configured to facilitate the movement of the dishwasher door between the closed position C, the drying position D, and the open position O. Specifically, the rotation arm 22 of the dishwasher door balance assembly 16 rotates counterclockwise to pivot the dishwasher door 14 from the closed position C, the drying position D, and the open position O. As shown in FIG. 6, the dishwasher door balance assembly 16 includes the hinge bracket 18, the hinge 20, an embossment feature 82, a bracket cut-out 84, the rotation arm 22, a friction sleeve 86, a connector element 87, and the first biasing element 32. The dishwasher door balance assembly 16 may also include a second biasing element 88 as shown in FIG. 7.

[0044] With continual reference to FIG. 6, the hinge bracket 18 may be coupled with both the door frame 50 and the first support 62 when the dishwasher door balance assembly 16 is positioned at the first side wall 40. As such, the hinge bracket 18 may extend between the door frame 50 and the first support 62. Alternatively, the hinge bracket 18 may be attached to both the door frame 50 and the second support 66 when the dishwasher door balance assembly 16 is positioned at the second side wall 42. As such, the hinge bracket 18 may extend between the door frame 50 and the second support 66.

[0045] The hinge bracket 18 forms a first surface 90 and a second surface 92 opposite the first surface 90. Both the first surface 90 and the second surface 92 have an area defined by an attachment leg 94, an arcuate leg 96, a top leg 98, a side leg 100, and a bottom leg 102. The hinge bracket 18 is positioned such that the second surface 92 is adjacent to either the first side wall 40 or the second side wall 42 and the first surface 90 is disposed adjacent to the rotation arm 22. The first surface 90 is configured to impair the passage of the rotation arm 22 across the first surface 90 via a frictional force generated between the first surface 90 and the friction sleeve 86 disposed on the rotation arm 22.

[0046] Referring still to FIG. 6, the hinge 20 may be formed by the hinge bracket 18. Alternatively, the hinge 20 may be attached to the hinge bracket 18 via a welding process or through various fasteners. The hinge 20 is positioned on and extends away from the first surface 90 of the hinge bracket 18. Specifically, the hinge 20 may be located adjacent to where the side leg 100 and the bottom leg 102 of the hinge bracket 18 meet. The hinge 20 may define a substantially cylindrical body configured to facilitate the pivoting of the rotation arm 22 about a rotational axis 104 of the hinge 20.

[0047] The rotational axis 104 of the hinge 20 may extend substantially parallel to the lateral extension of the hinge 20 from the first surface 90 of the hinge bracket 18. The rotation arm 22 is configured to pivot about the rotational axis 104 of the hinge 20. Further, the hinge 20 defines a vertical axis 106 and a horizontal axis 26 that each extend substantially orthogonal from the other. The vertical axis 106 and the horizontal axis 26 may be aligned with the vertical and the horizontal axis of symmetry of the hinge 20, respectively. As such, the hinge 20 may be substantially reflected across the vertical axis 106 and across the horizontal axis 26.

[0048] With continued reference to FIG. 6, the embossment feature 82 may be formed by the hinge bracket 18. Alternatively, the embossment feature 82 may be attached to the first surface 90 of the hinge bracket 18 via a welding process or with other fasteners. The embossment feature 82 is positioned on and extends away from the first surface 90 of the hinge bracket 18. As such, the embossment feature 82 forms a protrusion rising from the first surface 90 of the hinge bracket 18. The embossment feature 82 may be positioned proximate to where the bottom leg 102 and the attachment leg 94 of the hinge bracket 18 meet. Additionally, the embossment feature 82 may be substantially aligned with the horizontal axis 26 of the hinge 20.

[0049] The embossment feature 82 is further aligned with a rotational arc of the rotation arm 22. As such, the embossment feature 82 is configured to interface with the friction sleeve 86 disposed on the rotation arm 22 when the dishwasher door 14 transitions to the drying position D. Accordingly, the embossment feature 82 functions to partially maintain the rotation arm 22 and the dishwasher door 14 in the drying position D.

[0050] The bracket cut-out 84 is formed by the hinge bracket 18 and provides a recessed portion in the first surface 90 of the hinge bracket 18. The bracket cut-out 84 may be formed partially within the bottom leg 102 and extend substantially inwards towards the arcuate leg 96 and the top leg 98 of the hinge bracket 18. The bracket cut-out 84 is positioned substantially inferior to and aligned with the embossment feature 82.

[0051] The bracket cut-out 84 provides a recessed portion in the hinge bracket 18 to facilitate substantially frictionless movement of the friction sleeve 86, as the friction sleeve 86 moves with the rotation arm 22 along the rotational arc. Specifically, the bracket cut-out 84 is positioned such that the friction sleeve 86 may be received by the recess formed by the bracket cut-out 84. As such, the bracket cut-out 84 may facilitate the transition of the dishwasher door 14 from the closed position C to the drying position D by receiving and facilitating a substantially frictionless traversal of the friction sleeve 86 into and across the bracket cut-out 84.

[0052] With continued reference to FIG. 6, the rotation arm 22 is fixed to the dishwasher door 14 at an attachment end 110 of the rotation arm 22 and coupled with the first biasing element 32 via the connector element 87 at the offset portion 24 of the rotation arm 22. Additionally, the rotation arm 22 may be rotatably coupled to the hinge 20 at a portion of the rotation arm 22 interposed between the attachment end 110 and the offset portion 24. Further, the rotation arm 22 may be integrally formed with the hinge 20.

[0053] The attachment end 110 and the offset portion 24 form opposite ends of the rotation arm 22. The attachment end 110 of the rotation arm 22 may be fixed to an inner surface of the dishwasher door 14. The attachment end 110 may be attached to the inner surface of the dishwasher door 14 via a weld or by other fasteners. Alternatively, the attachment end 110 and consequentially, the rotation arm 22, may be integrally formed with the interior surface of the dishwasher door 14.

[0054] As illustrated in FIG. 11A, the offset portion 24 of the rotation arm 22 may be vertically offset from the horizontal axis 26 of the hinge 20 when the dishwasher door 14 is in the closed position C. Specifically, the offset portion 24 may be positioned vertically inferior to the horizontal axis 26 of the hinge 20 when the dishwasher door 14 is in the closed position C. As such, the rotation arm 22 may extend vertically towards the first bottom railing 34 from the hinge 20. As illustrated in FIG. 11B, in the drying position D, the offset portion 24 of the rotation arm 22 may be vertically offset from the horizontal axis 26 of the hinge 20. Specifically, in the drying position D, the offset portion 24 of the rotation arm 22 may be positioned vertically inferior to the horizontal axis 26 of the hinge 20. However, in the drying position D, the rotation arm 22 is positioned superior to the location of the rotation arm 22 when the rotation arm 22 is in the closed position C. As illustrated in FIG. 11C, in the open position O, the offset portion 24 is positioned superior to the horizontal axis 26. Accordingly, in operation, the offset portion 24 rotates counterclockwise, crossing the horizontal axis 26 of the hinge 20, such that the offset portion 24 may be positioned superior to the horizontal axis 26 when the dishwasher door balance assembly 16 is in the open position O.

[0055] Referring back to FIGS. 6 and 7, the offset portion 24 of the rotation arm 22 may be connected with the first biasing element 32 and the second biasing element 88. Additionally, the offset portion 24 is connected with the connector element 87, whereby the first biasing element 32 may be linked to the offset portion 24 via the connector element 87.

[0056] Referring now to FIGS. 8 and 9, the offset portion 24 forms a connection feature by which the offset portion 24 is connected to the first biasing element 32 and / or the second biasing element 88. Specifically, the connection feature of the offset portion 24 is formed of the first member 28 and the second member 30, wherein the first member 28 is positioned superior to the second member 30. The first member 28 and the second member 30 define a gap 89 therebetween as shown in FIG. 8. Alternatively, the offset portion 24 may include the first member 28 without the second member 30 as shown in FIG. 9.

[0057] Referring to FIGS. 8 and 9, the first member 28 may form a hook, or in other words, the first member 28 may have a substantially hooked shape. As such, the first member 28 may form a first shank 114 that vertically extends from a first bend 116 of the first member 28. A first rise 118 of the first member 28 extends from the portion of the first bend 116 opposite the first shank 114. Together, the first shank 114, the first bend 116, and the first rise 118 cooperate to define a first gap 120 of the first member 28. As shown in the configuration illustrated in FIG. 8, the first member 28 may form a substantially planar edge 128 that extends to a stop flange 130. Alternatively, as shown in the configuration illustrated in FIG. 9, the first shank 114 may form a biasing aperture 122 configured to receive a first hook 124 of the second biasing element 88. The biasing aperture 122 may be positioned adjacent to a distal-most edge 126 of the first shank 114 relative to the first bend 116.

[0058] Referring to FIG. 8, the second member 30 forms a hook, or in other words, the second member 30 has a substantially hooked shape. As such, the second member 30 forms a second shank 134 that vertically extends from a second bend 136 of the second member 30. A second rise 138 of the second member 30 extends from the portion of the second bend 136 opposite the second shank 134. Together, the second shank 134, the second bend 136, and the second rise 138 cooperate to define a second gap 140 of the second member 30.

[0059] Referring back to FIG. 6, the friction sleeve 86 may be positioned on the first member 28. Further, the friction sleeve 86 may be fitted or crimped around the exterior of the first member 28. Specifically, a portion of the friction sleeve 86 may be received by the gap 89 formed between the first member 28 and the second member 30. Additionally, a portion of the friction sleeve 86 may be fitted or crimped to the planar edge 128 of the first member 28 as shown in FIG. 8. As such, the stop flange 130 of the first member 28 may assist in hindering the removal of the friction sleeve 86 from the first member 28. Alternatively, as shown in FIG. 9, the friction sleeve 86 may be fitted or crimped around a peripheral portion 83 of the offset portion 24. The peripheral portion 83 may be a region of the offset portion 24 that is proximate to the attachment end 110, relative to the first member 28 and the second member 30. In other words, the peripheral portion 83 may be a region of the offset portion 24 that extends between the first member 28 and the second member 30 and the attachment end 110.

[0060] With continued reference to FIG. 6, the friction sleeve 86 may be configured to contact the embossment feature 82 to hinder the counterclockwise rotation of the rotation arm 22. As such, the friction sleeve 86 may be configured to cooperate with the embossment feature 82 to create a frictional force resisting the counterclockwise rotation of the rotation arm 22. Specifically, the friction sleeve 86 and the embossment feature 82 may function to maintain the dishwasher door 14 at the drying position D.

[0061] The friction sleeve 86 may be configured to contact the first surface 90 of the hinge bracket 18, frictionally interfacing with the first surface 90 to generate a frictional force resisting the counterclockwise rotation of the rotation arm 22 past the first surface 90. This frictional force may be opposed to the force of gravity urging the rotation arm 22 to rotate counterclockwise and transition the dishwasher door 14 into the open configuration O. As such, the counterclockwise rotation of the rotation arm 22 may be hindered, and the pivoting of the dishwasher door 14 from the drying position D to the open position O may be controlled.

[0062] Referring now to FIG. 10, the connector element 87 may include a first tubular body 142, a second tubular body 144 a first link 146, and a second link 148. The first link 146 is attached to a first end 150 of the first tubular body 142 and extends towards and is attached to a first end 152 of the second tubular body 144. The second link 148 is attached to a second end 154 of the first tubular body 142 and extends towards and is attached to a second end 156 of the second tubular body 144. The first tubular body 142, the second tubular body 144, the first link 146, and the second link 148 together define a slot 158 with a volume defined by the dimensions of the aforementioned components of the connector element 87. The first tubular body 142 and the second tubular body 144 each have a substantially cylindrical shape, such that both the first tubular body 142 and the second tubular body 144 have a substantially circular cross-section.

[0063] The connector element 87 may be coupled to the offset portion 24 via either the second member 30 as shown in FIG. 6 or, alternatively, the first member 28 as shown in FIG. 7. Specifically, the hook formed by either the first member 28 or the second member 30 may be received by the slot 158 of the connector element 87. Further, when coupled, either the first 114 or the second shank 134 of either the first 28 or the second member 30 may be interposed between the first link 146 and the second link 148 and positioned adjacent to the first tubular body 142. Further, the first tubular body 142 of the connector element 87 may be received by either the first gap 120 or the second gap 140 and rotatably interfaced with either the first bend 116 or the second bend 136, respectively. Consequentially, the connector element 87 may be configured to rotate about a connector axis 160 defined by the first tubular body 142 relative to either the first member 28 or the second member 30 as the rotation arm 22 pivots about the hinge 20.

[0064] The rotation of the connector element 87 about the connector axis 160 may alter the moment of force exerted against the rotation arm 22 by the first biasing element 32. As such, the moment of force experienced by the rotation arm 22 as the rotation arm 22 pivots the dishwasher door 14 between the closed position C, the drying position D, and the open position O may alter.

[0065] Referring back to FIGS. 6 and 7, the first biasing element 32 is connected to and exerts a force against the rotation arm 22 via the connector element 87. Specifically, the first biasing element 32 may be connected with the second tubular body 144 of the connector element 87 and a first railing aperture 162 of the first bottom railing 34 when the dishwasher door balance assembly 16 is coupled with the first side wall 40. Alternatively, when the dishwasher door balance assembly 16 is positioned adjacent to the second side wall 42, the first biasing element 32 may be connected with the second tubular body 144 of the connector element 87 and a second railing aperture 163 of the second bottom railing 80 as shown in FIG. 5. As such, the first biasing element 32 may extend between the connector element 87 and either the first bottom railing 34 or the second bottom railing 80.

[0066] With continued reference to FIGS. 6 and 7, the first biasing element 32 may be a compressible and expandable spring, configured to expand when subject to an oppositional force and recompress upon the removal of the oppositional force. The first biasing element 32 may be configured to exert a force upon the rotation arm 22 urging the rotation arm 22 to rotate counterclockwise about the hinge 20 when the dishwasher door 14 is in the closed position C and when the dishwasher door 14 is transitioning from the closed position C to the drying position D. Additionally, the first biasing element 32 is configured to exert a force upon the rotation arm 22 urging the rotation arm 22 to rotate clockwise about the hinge 20 when the dishwasher door 14 is transitioning between the drying position D and the open position O. As such, the first biasing element 32 may be configured to both urge the opening of the dishwasher door 14 to the drying position D, and then resist further pivoting of the dishwasher door 14 past the drying position D.

[0067] With reference to FIG. 7, the second biasing element 88 may be connected with the offset portion 24 of the rotation arm 22 and a biasing mount 91 fixed to either the first side wall 40 or alternatively, the second side wall 42. The biasing mount 91 may be positioned superior to the hinge bracket 18 and may be substantially aligned with the arcuate leg 96 of the hinge bracket 18. The first hook 124 of the second biasing element 88 may be connected with the first member 28 via the biasing aperture 122 defined by the first shank 114 of the first member 28.

[0068] The second biasing element 88 may be a compressible and expandable spring, configured to expand when subject to an oppositional force and recompress upon the removal of the oppositional force. The second biasing element 88 may be configured to exert a force upon the rotation arm 22 urging the rotation arm 22 to rotate counterclockwise about the hinge 20. Accordingly, the second biasing element 88 may exert a force upon the rotation arm 22 urging the dishwasher door 14 to pivot from the closed position C, to the drying position D, and to the open position O.

[0069] With continual reference to FIG. 7, the first biasing element 32 and the second biasing element 88 may exert forces upon the rotation arm 22 that are in opposition, urging the rotation arm 22 to rotate in opposing directions. Specifically, as the dishwasher door 14 transitions from the closed position C to the drying position D, the first biasing element 32 may exert a force urging the rotation arm 22 to rotate in the clockwise direction and the second biasing element 88 may exert a force on the rotation arm 22 urging the rotation arm 22 to rotate in the counterclockwise direction. In the drying position D, the first biasing element 32 may exert a force urging the rotation arm 22 to rotate clockwise and the second biasing element 88 may exert a force urging the rotation arm 22 to rotate counterclockwise. At the drying position D, the forces exerted by the first biasing element 32 and the second biasing element 88 may be substantially equivalent. As such, the rotation arm 22 may be maintained, or balanced at the drying position D until a force external to both the first biasing element 32 and the second biasing element 88 acts upon the rotation arm 22. As the rotation arm 22 begins to pivot from the drying position D to the open position O, the force exerted by the first biasing element 32 may continue to urge the rotation arm 22 to rotate in the clockwise direction, while the force exerted by the second biasing element 88 may continue to provide a force urging the rotation arm 22 to rotate in the counterclockwise direction. As such, the rotation of the rotation arm 22 and the resulting pivot of the dishwasher door 14 from the drying position D to the open position O may be controlled.

[0070] The operation of the dishwasher door balance assembly will be subsequently described with continual reference to FIGS. 11A-11C and 12A-12C. As shown in FIGS. 11A and 12A, the dishwasher door 14 may be maintained within the closed position C via the engagement between the locking mechanism 54 and the latch 52. In the closed position C, the first biasing element 32 may be partially extended, and as such, may exert a force against the rotation arm 22 urging the dishwasher door 14 to transition from the closed configuration C to the drying configuration D. When the locking mechanism 54 is disengaged from the latch 52, the force of gravity may cause the dishwasher door 14 to begin pivoting downwards. In combination with the force of gravity the first biasing element 32, may cause the rotation arm 22 to rotate counterclockwise about the hinge 20, pivoting the door downwards. As the dishwasher door 14 pivots from the closed position C, the friction sleeve 86 travels into and across the bracket cut-out 84 of the hinge bracket 18. The friction sleeve 86 may then contact the embossment feature 82 of the hinge bracket 18 as the dishwasher door 14 enters into the drying position D.

[0071] The dishwasher door 14 may be maintained or in other words, balanced, at the drying position D at least partially via the interaction between the friction sleeve 86 and the embossment feature 82 as shown in FIGS. 11B and 12B. The friction sleeve 86 may be configured to contact the embossment feature 82 when the dishwasher door 14 has been pivoted to the drying position D. The friction sleeve 86 and the embossment feature 82 may maintain the dishwasher door 14 in the drying position D through the generation of a frictional force between the friction sleeve 86 and the embossment feature 82. The frictional force may be substantially equal to and opposed to the force of gravity exerted on the dishwasher door 14. As such, the friction sleeve 86 and the embossment feature 82 may at least partially function to maintain the dishwasher door 14 in the drying position D.

[0072] Additionally, as shown in FIG. 11B, the dishwasher door 14 may be maintained or in other words, balanced, at the drying position D via a change in the moment of force exerted on the rotation arm 22 by the first biasing element 32. As the rotation arm 22 rotates counterclockwise from the closed position C, the connector element 87 may rotate clockwise about the connector axis 160. As the connector element 87 rotates, the lateral distance and the longitudinal distance between the second tubular body 144 of the connector element 87 and the rotational axis 104 may change. As such, the lateral moment and the longitudinal moment of force exerted by the first biasing element 32 may likewise change. Specifically, the lateral moment of force tending to urge the rotation arm 22 to rotate in the counterclockwise direction may become substantially equivalent to the longitudinal moment of force tending to urge the rotation arm 22 to rotate in the clockwise direction. As such, in the drying position D, the first biasing element 32 may reach an equilibrium state, wherein the first biasing element 32 exerts a nominal force against the rotation arm 22.

[0073] As shown in FIG. 12B, the dishwasher door 14 may be maintained or in other words, balanced, at the drying position D via the counteracting forces exerted on the rotation arm 22 by the first biasing element 32 and the second biasing element 88. Specifically, at the drying position D, the force exerted by the first biasing element 32 urging the rotation arm 22 to rotate in the clockwise direction may be substantially equivalent to the force exerted by the second biasing element 88 urging the dishwasher door 14 to rotate in the counterclockwise direction. Consequentially, the rotation arm 22 will experience a nominal net force and accordingly be maintained, or balanced, at the drying position D.

[0074] The dishwasher door 14 may be maintained, or in other words, balanced in the drying position D until an external force acts to further pivot the dishwasher door 14 towards the open position O. The rotation arm 22 may continue to rotate counterclockwise about the hinge 20 as the dishwasher door 14 pivots from the drying position D to the open position O. As the dishwasher door 14 pivots from the drying position D to the open position O, the first biasing element 32 may exert a force resisting the counterclockwise rotation of the rotation arm 22. Additionally, the friction sleeve 86 may contact the first surface 90 of the hinge bracket 18, creating a frictional force that further resists the counterclockwise rotation of the rotation arm 22. Together, the force exerted against the rotation arm 22 by the first biasing element 32 and the frictional force generated between the friction sleeve 86 and the hinge bracket 18 may control the counterclockwise rotation of the rotation arm 22 and the resulting pivot of the dishwasher door 14 from the drying position D to the open position O.

[0075] Additionally, as illustrated in FIGS. 12A-12C, the second biasing element 88 may exert a force against the rotation arm 22 urging the rotation arm 22 to rotate counterclockwise about the hinge 20. As such, the second biasing element 88 may exert a force opposed to the force exerted by the first biasing element 32. Accordingly, the first biasing element 32 and the second biasing element 88 together may control the counterclockwise rotation of the rotation arm 22 and the resulting pivot of the dishwasher door 14 from the drying position D to the open configuration O.

[0076] With reference to FIGS. 11C and 12C, the dishwasher door 14 may be maintained in the open position O via the frictional forces generated between the friction sleeve 86 and the first surface 90 of the hinge bracket 18. Additionally, as shown in FIG. 12C, the dishwasher door 14 may be maintained in the open position O via the force exerted on the rotation arm 22 by the second biasing element 88, resisting the clockwise rotation of the rotation arm 22 from the open position O, to the drying position D, and then to the closed position C.

[0077] The dishwasher door 14 may return from the open position O to the closed position C through the application of an external closing force. The combination of the generated frictional force between the friction sleeve 86 and the first surface 90 of the hinge bracket 18 and the exerted force of the second biasing element 88, may provide resistance to the external closing force. Further, at the drying position D, the first biasing element 32 may further resist the external closing force. As the dishwasher door 14 pivots to the closed position C, the rotation arm 22 rotate clockwise until the top portion 58 of the dishwasher door 14 is proximate to the door frame 50 and the locking mechanism 54 engages the latch 52, securing the dishwasher door 14 to the door frame 50.

[0078] Use of the present assembly may provide for a variety of advantages. For example, the dishwasher door balance assembly 16 may facilitate an energy efficient and automatic method to dry dishware and utensils after a wash cycle of the dishwasher 10. Specifically, the dishwasher door balance assembly 16 may allow for the steam and hot air generated by the wash cycle to circulate through the washing chamber 46, drying the dishware and utensils, before exiting at a controlled rate through the top portion of the opening 44. As such, energy is conserved by utilizing the steam and hot air generated by the wash cycle to dry the dishware and utensils, as opposed to expending additional energy to dry the dishware and utensils. Further, the present assembly may allow for a controlled passage of steam and hot air out of the opening 44 of the dishwasher 10. Specifically, only the top portion of the opening 44 may be uncovered at the drying position D. As such, the majority of steam and hot air within the washing chamber 46 may pass through this partial opening. When the user transitions the dishwasher door 14 to the open position O, there may be only trace amounts of steam and hot air present still within the washing chamber 46. This may prevent the steam and hot air from contacting the user when the user transitions the dishwasher door 14 to the open position O. Additional benefits and advantages may be realized and / or achieved.
