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.
BACKGROUND OF THE TECHNOLOGYConventional 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.
SUMMARY OF THE TECHNOLOGYOne 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:
The following description is provided in relation to several examples which may share common characteristics and features. 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.
The rack 25 may be any type of rack capable of supporting items. For example, in a dishwasher, the rack 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 in
The guide system 30 may facilitate the movement of the crockery rack 25 in and out of the compartment 15, may support the rack 25 and may be any type of guide system capable of moving the rack 25 in a substantially horizontal direction. For example, as illustrated in
The protrusion devices 35 may have any shape that reduces the likelihood of the rack 25 becoming lodged in a recess or on a ridge of the door 10 and may be rotatably attached to the rack 25 or fixedly attached to the rack 25 (i.e., stationary). In the rotatable configuration, each protrusion 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 each protrusion device 35 may be large enough so that the protrusion device 35 may roll over any recess or ridge on the door 10, without catching or snagging, as the door 10 is being closed against the rack 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 the rack 25. That is, the protrusion devices 35 may rotate around the substantially horizontal axis within an angular range limited to less than 360 degrees. The protrusion 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, the protrusion 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 the protrusion devices 35 to partially roll over and/or slide against the recesses or ridges on the door 10 without catching or snagging as the door 10 is being closed against the rack 25.
In the stationary (i.e., non-rotatable) configuration, the protrusion devices 35 may not rotate around any axis. Instead, the protrusion devices 35 may slide against the door 10 as the door 10 is pivoted toward the closed positions. In addition, the protrusion 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 the protrusion 35 to slide against the recesses or ridges on the door 10 without catching or snagging as the door 10 is being closed against the rack 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, the protrusion devices 35 may be formed from one piece with the rack 25. Alternatively, the protrusion devices 35 may be formed separately from the rack 25 and later permanently or detachably attached to the rack 25. Further, the detachably attached protrusion devices 35 may be retroactively fitted to conventional racks of kitchen appliances.
Although
The clip portion 50 may form a continuous structure with the contacting portion 55 at an upper end of the recess 60 and may be separated from the contacting portion 55 at a lower end of the recess 60 so that the recess 60 may be closed at its upper end and open at its lower end. The forward edge of the rack 25 may be received in the recess 60. The recess 60 may be sized so that the forward edge of the rack 25 may be retained within the recess 60 via gravity and friction. In addition, a lower portion of the clip portion 50 may be biased against the contacting portion 55 so that the biasing force exerted by the clip portion 50 may retain the forward edge of the rack 25 in conjunction with or instead of friction. Although
The contacting portion 55 may contact the door 10 when the door 10 is pivoted toward the closed position and may have any shape that reduces the likelihood of the rack 25 becoming lodged in a recess or on ridge of the door 10. For example, the contacting portion 55 may have a semi-circular or flat shape. The surfaces of the contacting portions 55 may be formed from low-friction materials such as, for example, polytetrafluoroethylene (PTFE).
Although
In an alternate configuration, the door 65 and the engagement regions 70 may be used without the protrusions 35 and the protrusions 35a. In this configuration, the modified door 65 may directly contact the rack 25. In addition, the engagement regions 70 may project from a surface of the door 65 so that the engagement regions 70 are the only portions of the door 65 that contacts the rack 25. Further, the engagement regions 70 may have any shape that may allow engagement regions 70 to slide or roll relative to the rack 25 without catching or snagging as the door 10 is being closed against the rack 25.
For each of the above configurations, the engagement regions 70 may be formed from a single material with the door 65 or may be formed separately from the door 65 and then later attached to the door 65. In addition, the engagement regions 70 may be permanently or detachably attached to the door 65, or they may be retrofit to existing doors.
For each of the above configurations, the protrusions 35, protrusions 35a and/or rack 25 may initially engage the door 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, the protrusions 35 and/or protrusions 35a may maintain contact with the door 10 until the door 10 reaches the closed position (approximately 90 degrees). However, the protrusions 35 and/or protrusions 35a can be designed such that they contact the door 10 to a lesser extent, e.g., when the door 10 is pivoted to a sufficient angle such that there is little chance that snagging can occur and engagement between the rack 25 and the door 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.
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.
