Abstract
A rack for supporting objects within a kitchen appliance has a first side with a first front end and a second side opposing the first side with a second front end. The rack also has a front side extending from the first front end to the second front end and opposing a door of the appliance. The rack further has at least one protrusion member supported on the front side of the rack. The at least one protrusion member is positioned so that the door of the appliance contacts the at least one protrusion member instead of the front side of the rack.
Description
- The present technology relates to kitchen appliances, in particular to appliance racks having protrusion devices, e.g., dishwashers, ovens, toaster ovens, microwave ovens and refrigerators.
- Conventional kitchen appliances utilize racks to hold various objects within the confines of the appliance. The racks are typically configured to move in and out of the appliance in order to provide access to the objects on the racks. For example, a dishwasher typically contains at least one crockery rack, usually two, each with a number of upstanding tines to hold the crockery in an upright position. The crockery positioned on the rack is accessed by first opening the dishwasher door and then moving the crockery racks out of the dishwasher. In order to wash the crockery loaded on the crockery racks, each rack must be individually moved inside the dishwasher and then the door of the dishwasher must be closed.
- Time and energy could be saved by combining the above steps. However, using the dishwasher door to move the upper rack of the dishwasher can be problematic. In particular, the interior surface of a conventional dishwasher door typically includes ridges and recesses for sound baffling and to house various components. The upper rack can become snagged on these ridges and recesses when the door is brought into contact with the upper rack, thereby rendering the upper rack and the door immovable until the upper rack and the door are separated.
- One aspect of the disclosed technology relates to a rack for supporting objects within a kitchen appliance that addresses one or more of the shortcomings of the prior art.
- Another aspect of the disclosed technology relates to a protrusion member configured to be removably positioned on a rack of a kitchen appliance, the rack supporting objects within the kitchen appliance. The protrusion member is positioned and adapted to engage a door of the kitchen appliance without becoming caught on a portion of the door.
- Another aspect of the disclosed technology relates to a rack for supporting objects within a kitchen appliance including a first side having a first front end and a second side opposing the first side and having a second front end. The rack also includes a front side extending from the first front end to the second front end and opposing a door of the appliance. The rack further includes at least one protrusion member supported on the front side of the rack. The at least one protrusion member is positioned so that the door of the appliance (e.g., during a closing operation) contacts the at least one protrusion member instead of or in addition to the front side of the rack.
- Another aspect of the disclosed technology relates to a door of a kitchen appliance that includes engagement regions that engage a rack of the kitchen appliance when the door is pivoted toward a closed position. The engagement regions are configured to engage a rack and/or one or more protrusions on the rack as the door is closed, e.g., at an angle up to about 40-90 degrees (e.g., 60 degrees) with respect to a horizontal plane without becoming snagged.
- Another aspect of the disclosed technology relates to a kitchen appliance. The kitchen appliance includes a compartment and a door to selectively provide access to the compartment. The kitchen appliance also includes at least one rack having a front side opposing the door, the at least one rack being movably positioned (e.g., slidingly) within the compartment. The kitchen appliance further includes at least one protrusion member supported on the front side of the rack. The at least one protrusion member is positioned so that the door (e.g. during a closing operation) contacts the at least one protrusion member instead of or in addition to the front side of the rack. When the rack is fully extended, the at least one protrusion member initially engages the door when the door is at an angle of about 40-60 degrees.
- Another aspect of the disclosed technology relates to a kitchen appliance. The kitchen appliance includes a compartment, a door to selectively provide access to the compartment and at least one rack having a front side opposing the door, the at least one rack being positioned within the compartment. At least one engagement region is positioned on the door. In addition, the at least one engagement region is positioned so that when the at least one rack is fully extended, the at least one engagement region initially engages the at least one rack without snagging at an angle of about 40-60 degrees.
- Another aspect of the disclosed technology relates to a method for moving a rack that supports objects within a kitchen appliance. The method includes pivoting a door of the kitchen appliance from an open position toward a closed position until the door contacts at least one protruding member of the rack, the at least one protruding member being positioned on the rack at a location closest to the door. The method may also include moving the rack in a substantially horizontal direction by continuing to pivot the door toward the closed position after the protruding member and the door contact each other. The rack and the door are independently movable when the at least one protrusion member and the door are not in contact with each other.
- Other aspects, features, and advantages of this technology will become apparent from the following detailed description when taken in conjunction with the accompanying drawings, which are a part of this disclosure and which illustrate, by way of example, principles of this technology.
- The accompanying drawings facilitate an understanding of the various examples of this technology. In such drawings:

It is to be understood that one or more features of any one example may be combinable with one or more features of the other examples. In addition, any single feature or combination of features in any of the examples may constitute additional examples.
-
FIG. 1 is a schematic view of akitchen appliance 5. Thekitchen appliance 5 may be, for example, a dishwasher for washing and/or drying crockery items, such as dishes, frying pans, cookie sheets, cutting boards, bowls, pots, etc. Kitchenappliance 5 may include a manuallyopenable door 10 and acompartment 15. Thedoor 10 may be openable to allow access to thecompartment 15 and may form a generally water/air tight seal relative to thecompartment 15 when closed. Thedoor 10 may move between an open position and a closed position by pivoting around apivot 20. Thecompartment 15 may include at least onerack 25. - The
rack 25 may be any type of rack capable of supporting items. For example, in a dishwasher, therack 25 may support crockery items that are to be cleaned and/or dried and may be a wire-type rack such as the one illustrated inFIGS. 1-4 . Therack 25 may be supported by aguide system 30 located inside thecompartment 15 and may include one ormore protrusion devices 35. It is contemplated that therack 25 may be an upper rack located above a lower rack (not shown). - The
guide system 30 may facilitate the movement of thecrockery rack 25 in and out of thecompartment 15, may support therack 25 and may be any type of guide system capable of moving therack 25 in a substantially horizontal direction. For example, as illustrated inFIG. 1 , theguide system 30 may include a plurality ofguide wheels 40 mounted on a side of thecompartment 15 and atrack 45 supported between theguide wheels 40. One or more wheels (not shown) attached to therack 25 may be positioned within thetrack 45. When moving therack 25 in or out of thecompartment 15, thetrack 45 may move between theguide wheels 40 in a substantially horizontal direction. At the same time, the wheels (not shown) on therack 25 may move along thetrack 45. -
FIG. 2A illustrates an example in which at least oneprotrusion device 35 may be attached (permanently or detachedly) to therack 25. Eachprotrusion device 35 may be supported on a forward edge of therack 25 that would otherwise be the first portion of therack 25 to contact thedoor 10 when thedoor 10 is pivoted toward the closed position. By locating eachprotrusion device 35 at this position on therack 25, thedoor 10 will contact theprotrusion devices 35 instead of therack 25, itself, when thedoor 10 is pivoted toward the closed position. - The
protrusion devices 35 may have any shape that reduces the likelihood of therack 25 becoming lodged in a recess or on a ridge of thedoor 10 and may be rotatably attached to therack 25 or fixedly attached to the rack 25 (i.e., stationary). In the rotatable configuration, eachprotrusion device 35 may include one or more wheels configured to rotate completely around a substantially horizontal axis located on the forward edge of the rack 25 (e.g. one of the horizontal wires of a wire rack). The diameter of eachprotrusion device 35 may be large enough so that theprotrusion device 35 may roll over any recess or ridge on thedoor 10, without catching or snagging, as thedoor 10 is being closed against therack 25. - Instead of rotating completely around the horizontal axis, the
protrusion devices 35 may rotate partially around the substantially horizontal axis located on the forward edge of therack 25. That is, theprotrusion devices 35 may rotate around the substantially horizontal axis within an angular range limited to less than 360 degrees. Theprotrusion devices 35 that rotate partially around the substantially horizontal axis may include one or more wheels configured to have a limited range of rotation around the substantially horizontal axis. Alternatively, theprotrusion devices 35 that rotate partially around the horizontal axis may have any shape other than a wheel shape such as, for example, a semi-circular shape, flat shape or any other shape that may allow theprotrusion devices 35 to partially roll over and/or slide against the recesses or ridges on thedoor 10 without catching or snagging as thedoor 10 is being closed against therack 25. - In the stationary (i.e., non-rotatable) configuration, the
protrusion devices 35 may not rotate around any axis. Instead, theprotrusion devices 35 may slide against thedoor 10 as thedoor 10 is pivoted toward the closed positions. In addition, theprotrusion devices 35 may be any shape such as, for example, a wheel shape, semi-circular shape, flat shape or any other shape that may allow theprotrusion 35 to slide against the recesses or ridges on thedoor 10 without catching or snagging as thedoor 10 is being closed against therack 25. - For the rotatable and stationary configurations, the surfaces of the
protrusion devices 35 may be formed from low-friction materials such as, for example, polytetrafluoroethylene (PTFE). In addition, theprotrusion devices 35 may be formed from one piece with therack 25. Alternatively, theprotrusion devices 35 may be formed separately from therack 25 and later permanently or detachably attached to therack 25. Further, the detachably attachedprotrusion devices 35 may be retroactively fitted to conventional racks of kitchen appliances. - Although
FIG. 2A illustrates threeprotrusion devices 35, any number ofprotrusion devices 35 can be attached to therack 25. In addition, the combined and individual widths of theprotrusion devices 35 can be any fraction of the width of therack 25. Furthermore, althoughFIG. 2A illustrates theprotrusion devices 35 being partially below and partially in front of the forward edge of therack 25, theprotrusion devices 35 may be partially or completely in front of and/or partially or completely below the forward edge of therack 25. For example, theprotrusion device 35 may be partially below the forward edge of therack 25 so that the door initially engages with theprotrusion device 35 and then may contact/engage with the front of therack 25 and/or theprotrusion 35 for the remainder of the closing operation. Moreover, the locations of theprotrusions 35 may be aligned with particular ridges and/or recesses on thedoor 10 or may be aligned with smooth portions of thedoor 10. Also, theprotrusion devices 35 may include any combination of shapes and/or any combination of configurations (e.g., rotatable and stationary configurations). -
FIG. 2B illustrates another exemplary configuration that includesprotrusion devices 35 a, which are clipped onto and removably attached to therack 25. Similar to theprotrusion devices 35, theprotrusion devices 35 a may be supported on the forward edge of therack 25 that would otherwise be the first portion of therack 25 to contact thedoor 10 when thedoor 10 is pivoted toward the closed position. Theprotrusion devices 35 a may include aclip portion 50, a contactingportion 55 and arecess 60 defined by theclip portion 50 and the contactingportion 55. - The
clip portion 50 may form a continuous structure with the contactingportion 55 at an upper end of therecess 60 and may be separated from the contactingportion 55 at a lower end of therecess 60 so that therecess 60 may be closed at its upper end and open at its lower end. The forward edge of therack 25 may be received in therecess 60. Therecess 60 may be sized so that the forward edge of therack 25 may be retained within therecess 60 via gravity and friction. In addition, a lower portion of theclip portion 50 may be biased against the contactingportion 55 so that the biasing force exerted by theclip portion 50 may retain the forward edge of therack 25 in conjunction with or instead of friction. AlthoughFIG. 2B illustrates theprotrusion devices 35 a as being clipped onto horizontal wires of therack 25, theprotrusions 35 a may be clipped onto vertical wires of therack 25. - The contacting
portion 55 may contact thedoor 10 when thedoor 10 is pivoted toward the closed position and may have any shape that reduces the likelihood of therack 25 becoming lodged in a recess or on ridge of thedoor 10. For example, the contactingportion 55 may have a semi-circular or flat shape. The surfaces of the contactingportions 55 may be formed from low-friction materials such as, for example, polytetrafluoroethylene (PTFE). - Although
FIG. 2B illustrates threeprotrusion devices 35 a, any number ofprotrusion devices 35 a can be attached to therack 25. In addition, the combined and individual widths of theprotrusion devices 35 a can be any fraction of the width of therack 25. Moreover, the locations of theprotrusion devices 35 a may be aligned with particular ridges and/or recesses on thedoor 10 or may be aligned with smooth portion of thedoor 10. Furthermore, any combination ofprotrusion devices 35 andprotrusion devices 35 a may be attached to therack 25. Also, similar to theprotrusions 35, theprotrusions 35 a may be retrofitted onto conventional racks of kitchen appliances. -
FIG. 3 illustrates a modifieddoor 65 that may include one ormore engagement regions 70. The one ormore engagement regions 70 may be aligned with theprotrusions 35 and/or theprotrusions 35 a and may engage theprotrusions 35 and/or theprotrusions 35 a as thedoor 65 is pivoted toward a closed position, e.g., theengagement regions 70 may be moulded on the upper part of thedoor 10 to engage theupper rack 25. The number ofengagement regions 70 may be the same as or different from the number ofprotrusions 35 and/orprotrusions 35 a. In addition, the one ormore engagement regions 70 may extend from an upper portion of thedoor 65 to a lower portion of thedoor 65. In one configuration, the one ormore engagement regions 70 may be recesses that receiveprotrusions 35 and/or theprotrusions 35 a. In another configuration, the one ormore engagement regions 70 may be raised portions having similar shapes as the correspondingprotrusion 35 orprotrusion 35 a. For example, eachengagement region 70 may include one or more wheels, may have a semi-circular shape or may have a flat shape. In addition, the one ormore engagement regions 70 may be formed from low-friction materials such as, for example, polytetrafluoroethylene (PTFE). Further, theengagement regions 70 may extend a distance that is less than the full extent of thedoor 65. - In an alternate configuration, the
door 65 and theengagement regions 70 may be used without theprotrusions 35 and theprotrusions 35 a. In this configuration, the modifieddoor 65 may directly contact therack 25. In addition, theengagement regions 70 may project from a surface of thedoor 65 so that theengagement regions 70 are the only portions of thedoor 65 that contacts therack 25. Further, theengagement regions 70 may have any shape that may allowengagement regions 70 to slide or roll relative to therack 25 without catching or snagging as thedoor 10 is being closed against therack 25. - For each of the above configurations, the
engagement regions 70 may be formed from a single material with thedoor 65 or may be formed separately from thedoor 65 and then later attached to thedoor 65. In addition, theengagement regions 70 may be permanently or detachably attached to thedoor 65, or they may be retrofit to existing doors. - For each of the above configurations, the
protrusions 35,protrusions 35 a and/orrack 25 may initially engage thedoor 10 when the door is rotated up to about 40-60 degrees with respect to an initial open (horizontal) position without becoming caught or snagged on a portion of the door. After the initial contact, theprotrusions 35 and/orprotrusions 35 a may maintain contact with thedoor 10 until thedoor 10 reaches the closed position (approximately 90 degrees). However, theprotrusions 35 and/orprotrusions 35 a can be designed such that they contact thedoor 10 to a lesser extent, e.g., when thedoor 10 is pivoted to a sufficient angle such that there is little chance that snagging can occur and engagement between therack 25 and thedoor 10 is acceptable to complete the closing process. Such “sufficient angle” may be less than 90 degrees, e.g., 80 degrees, 70 degrees, 60 degrees or less. -
FIGS. 4 and 5 illustrate a method for using the door 10 (or the modified door 65) to move therack 25 toward thecompartment 15. The method may begin when the door 10 (or the modified door 65) is in an open position (i.e., in a horizontal configuration) and therack 25 is outside of thecompartment 15. First, the door 10 (or the modified door 65) may be pivoted around thepivot 20 until the door 10 (or the modified door 65) engages theprotrusion devices 35, theprotrusion devices 35 a and/or therack 25. Upon contacting theprotrusion devices 35,protrusion devices 35 a and/or therack 25, the door 10 (or the modified door 65) may continue pivoting around thepivot 20. At the same time, theprotrusion devices 35, theprotrusion devices 35 a and/or therack 25 may rotate or slide against thedoor 10, and therack 25 may be moved substantially horizontally toward thecompartment 15 until therack 25 is completely inside thecompartment 15 and the door 10 (or the modified door 65) is in the closed position (i.e., in a vertical configuration). It should be understood that therack 25 and the door 10 (or the modified door 65) are independently movable when theprotrusion devices 35, theprotrusion device 35 a or therack 25 is in engagement with the door 10 (or the modified door 65). - While the technology has been described in connection with what are presently considered to be the most practical and preferred examples, it is to be understood that the technology is not to be limited to the disclosed examples, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the disclosure.
