Description

TECHNICAL FIELD

The present disclosure relates to a storage assembly for a household appliance.

BACKGROUND

Refrigerator door bins are generally known and can include a bin unit configured for removable assembly with a liner of the door. The configuration of the bin unit separate from the liner is generally a product of the material and process limitations associated with the liner, which is usually formed using a vacuum-forming process. The bin unit is generally more suitable for an injection molding or similar process. Accordingly, the bin unit and liner are separately made and must be assembled together. Most such assemblies facilitate selective placement of the bin within a number of available positions and ease of disassembly and repositioning of the bin by a consumer. Further, many bins are made of or include a transparent or translucent material.

DETAILED DESCRIPTION

As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
As used in the specification and the appended claims, the singular form “a,” “an,” and “the” comprise plural referents unless the context clearly indicates otherwise. For example, reference to a component in the singular is intended to comprise a plurality of components.
The term “substantially” or “about” may be used herein to describe disclosed or claimed embodiments. The term “substantially” or “about” may modify a value or relative characteristic disclosed or claimed in the present disclosure. In such instances, “substantially” or “about” may signify that the value or relative characteristic it modifies is within ±0%, 0.1%, 0.5%, 1%, 2%, 3%, 4%, 5% or 10% of the value or relative characteristic.
When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). The term “and/or” includes any and all combinations of one or more of the associated listed items.
Although the terms first, second, third, etc. may be used to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.
Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
Referring generally to the figures, a refrigerator 100 is provided. The refrigerator 100 may include a main body such as a cabinet 102 that may form a fresh food compartment 104. One or more doors 106 may be pivotally attached to the cabinet 102 and the doors 106 may be configured to pivot about the cabinet 102 between an open position and a closed position. When the one or more doors 106 are in the open position, a user may access the fresh food compartment 104. The doors 106 may include an inner liner 108, that may face the fresh food compartment 104, and an door skin 110 that may form an exterior surface of the refrigerator door 106. The inner liner 108 may include a number of vertical walls, such as a first vertical wall 112, a second vertical wall 114, and a third vertical wall 116 extending between the first and second vertical walls 112, 114. The first, second, and third vertical walls 112, 114, 116 may form a pocket 118 that may be recessed with respect to an inner surface 120 of the inner liner 108. For purposes of clarity, the inner surface 120 faces the fresh food compartment 104 when the door is closed.
The first vertical wall 112, the second vertical wall 114, or both may include a supporting portion that may be configured to support a bin 122 or portions or a bin enclosure 125. As an example, the first vertical wall 112 may include a first protrusion 124, a second protrusion 126 and a relief region 128 disposed therebetween. The first protrusion 124 may include a first load-bearing surface 186 and the second protrusion 126 may include a second load-bearing surface 188 (FIG. 4A). The bin 122 may include an enclosure portion 130 that, when assembled to the inner liner 108, may close off portions of the pocket 118 and retain food or beverage items disposed in the bin 122. A retention portion 132 may extend substantially orthogonally from the enclosure portion 130 and the retention portion 132 may be configured to engage the supporting portion to fix the bin or bin enclosure portion to the inner liner 108.
The retention portion 132 may include a fourth vertical wall 134 that may define a slot 136 that may be configured to receive at least one of the first protrusion 124 or the second protrusion 126. The retention portion 132 may include a retention protrusion 135 that may be inserted into the relief region 128 when the bin 122 is assembled to the inner liner 108. The retention portion 132 may include a first lip 156 that may extend from the fourth vertical wall 134 and the first lip 156 may lie against the first protrusion 124. The first lip 156 may be configured to prevent the bin 122 from being dislodged from the inner liner 108 in response to tipping the bin 122 towards the door skin 110. The retention protrusion 135 may be formed by a pair of vertical struts 138 and a number of horizontal struts 140 that may extend between the pair of vertical struts 138. In one or more embodiments, a portion of the first vertical wall 112 disposed in the relief region 128 may include a number of relief notches 142. The relief notches 142 may form a number of stiffening ribs 143 to stiffen the portion of the first vertical wall 112 disposed in the relief region 128.
The inner liner 108 may include a first horizontal extending wall 144 that may extend between the first vertical wall 112 and the second vertical wall 114. The first horizontal wall 144 may form a first food support surface 147 that may be configured to support food or beverages. In one or more embodiments, the inner liner 108 may include a V-shaped cross-section portion and the first horizontal wall 144 may form a portion of the V-shaped cross-section. As an example, a bottom portion of the V-shaped cross-section may include a nose 146 that may be tapered with respect to the food support surface 147. In one or more embodiments, the bin 122 may be formed by one or more plastic or polymeric materials by injection molding. Portions of the bin 122 such as the enclosure portion 130 may be formed by opaque material and other portions of the bin 122 including but not limited to the fourth vertical wall 134 and the second horizontal wall 170 may be formed by a translucent material.
FIG. 1 generally shows the refrigerator 100 with the doors 106 in a closed position and FIG. 2 generally shows the refrigerator 100 with the doors 106 in an open position. The refrigerator may be of the French-Door Bottom Mount type, but it is understood that this disclosure could apply to any type of refrigerator, such as a side-by-side, two-door bottom mount, or a top-mount type. As shown in FIGS. 1-2 , the refrigerator 100 may have a first internal storage chamber or the fresh food compartment 104 configured to refrigerate and not freeze consumables within the fresh food compartment 104, and a second internal storage chamber or a freezer compartment configured to freeze consumables within the freezer compartment during normal use. The refrigerator 100 includes cabinet walls that define the fresh food compartment 104 and the freezer compartment. The refrigerator 100 may have one or more doors 106 that provide selective access to the interior volume of the refrigerator 100 where consumables may be stored. As shown, the fresh food compartment doors are designated 106, and the freezer door is designated 107. It may also be shown that the fresh food compartment 104 may only have one door 106. The bins 122 described herein can also be disposed on the freezer door 107.
A number of bins 122 a-122 d, configured to store food and beverage items, may be fixed to the inner liner 108 of one or more of the doors 106. Typically, bins of different size and shapes may be arranged on the inner liner 108. One of the challenges with bins that are generally available is that the bins in certain location within the door include various interfaces to fix the bin to the inner liner.
FIG. 3 illustrates a cross-sectional view of a portion of the refrigerator door 106. For the purposes of clarity, portions of the inner liner 108 that are covered by the bin 122 are shown in dashed lines. The inner liner 108 and the door skin 110 may be fixed to one another and one or more seals or gaskets 148 may be disposed between the inner liner 108 and the door skin 110. One or more of the inner liner 108, door skin 110 and gaskets 148 may be formed from a multilayer thermoplastic polymer material including one or more barrier layers that are substantially impervious to nitrogen, oxygen, water vapor, carbon dioxide, and other such gasses whereby a vacuum can be maintained in an internal space between inner liner 108 and the door skin 110. The gasket 148 may include a thermoset material with or without fillers or reinforcements (i.e. fibers) and may optionally include a barrier coating.
One or more of the components 108, 110, 148 may optionally be made from metal or other suitable material. For example, the door skin 110 may be made from sheet metal, and inner liner 108 may be made from a multi-layer thermoformed polymer material having barrier properties. The door skin 110 may include a generally planar central sidewall portion 152, and four sidewalls 154A-154D that extend transversely from the central sidewall portion 152 to define an interior space that receives inner liner 108 when assembled. The inner liner 108 may include the first, second and third sidewalls 112, 114, 116 and the third sidewall 116 may be spaced apart from the central sidewall portion 152 when assembled. When assembled, the sidewalls 112, 114 are spaced inwardly from the sidewalls 154A, 154D, respectively, of door skin 110 to form a gap or space therebetween that may be filled with a porous filler material and evacuated to form a vacuum. The sidewalls 112, 114 may form the inner surface 120 of the inner liner 108 that faces the refrigerated compartment 104 when the doors 106 are in the closed position. The third sidewall 116 may be recessed towards the door skin 110 to form the recessed pocket 118.
FIG. 4 illustrates a cross-sectional-exploded view of a portion of the refrigerator door 106. The inner liner 108 includes a V-shaped cross-section portion that extends from the third vertical sidewall 114. The V-shaped cross-section portion includes the first horizontal wall 144 and the nose 146. In addition to the first horizontal wall 144, a second horizontal wall 158 may extend from the nose 146 towards the door skin 110. The first and second horizontal walls 144, 158 and the nose 146 may form a void 160 that may be configured to receive insulating filling. The first horizontal wall 144 may form the first food support surface 147 that may be raised with respect to the nose 146. The first food support surface 147 may converge with a first inner radius 162. The first inner radius may converge with the first protrusion 124.
The bin 122 is shown in an uninstalled position, spaced apart from the inner liner 108. The bin 122 may include the enclosure portion 130 that may extend in a direction parallel to the third vertical sidewall 114. A second horizontal wall 170 may extend from the enclosure portion 130 in a direction that may be substantially orthogonal to the enclosure portion 130. The second horizontal wall 170 may form a second support surface 172 that may be configured to support a number of food or beverage items.
The second horizontal wall 170 may cooperate with the retention features formed by the fourth vertical wall 134 to provide support for the bin 122. Because the second horizontal wall 170 may lie along the first horizontal wall 144, portions of the load of the bin or contents disposed therein may be supported by the first horizontal wall 144. Accordingly, a less robust and more adaptable or removable interface between the fourth vertical wall 134 and the first vertical wall 112 may be employed. The second horizontal wall 170 may define a number of slots 174 that may have an elongated shape. The slots 174 may be arranged so that the air may flow through the slots 174 to the storage area formed by the first horizontal wall 144 and the bin 122. While only one side of the bin 122 is illustrated, the side not shown may include substantially the same features described herein.
In one or more embodiments, a majority of the second horizontal wall 170 may lie along a portion of the first horizontal wall 144 such as the nose 146. The nose 146 or other portions of the first horizontal wall 144 may support the second horizontal wall 170 in the vertical direction. The second horizontal wall 170 may lie along the nose 146 so that the second horizontal wall 170 and the first horizontal wall 144 lie in a common plane. In other words, the first horizontal wall 144 and the second horizontal wall 170 may form a planar surface that may be configured to evenly support a number of food or beverage items stored within the bin 122. The planar surface between the second horizontal wall 170 and the food support surface 147 may provide a relatively seamless appearance for the bottom portion of the bin 122.
A lip 176 may extend from the fourth vertical wall 134 to the second horizontal wall 170. The lip 176 may include an edge 178 that may be configured to engage a portion of the food support surface 147 such as an inner edge 164 so that the fourth vertical wall 134, by way of the lip 176, is sandwiched between the retention members such as the first protrusion 124 and the second load bearing protrusion 126. The food support surface 147 may also include a front edge 182 that may be configured to abut against a rear edge 185 of the second horizontal wall 170. As an example, the edge 178 and the edge 180 of the food support surface 147 may fix the bin 122 so that the bin 122 is fixed to prevent movement of the bin in a width direction such as towards the first vertical wall 112 and the second vertical wall 114.
In one or more embodiments, the bin 122 may include a peripheral lip 190 that may extend from the enclosure portion 130. The peripheral lip 190 may be configured to route or transport condensate from the bin 122 to a bottom portion of the fresh food compartment 104 that may be provided with a drain configured to route the condensate to a drip pan (not illustrated). The peripheral lip 190 may also provide a finished surface for improved aesthetics.
FIG. 4A illustrates a detailed-perspective view of a portion of the inner liner 108. The food surface 147 may include the inner edge 164. The inner edge 164 and second protrusion 126 may engage portions of the bin 122 so that the bin 122 is detachably secured to the first horizontal wall 144. The inner edge 164 and portions of the first vertical wall 112 may form a recessed portion 184 that may receive the lip 176 of the fourth vertical wall 134. The lip 176 may be disposed in the recessed portion 184 so that the food support surface 147 and the lip 176 provide a generally seamless surface.
In one or more embodiments, the first protrusion 124 may have a first width W1 and a first height H1 and the second protrusion 126 may define a second height H2 that may be substantially equal to the first height H2. The relief region 128 may have a second width W2 and the third load-bearing protrusion 126 may have a third width W3. The second width W2 may be less than the first width W1 and may be greater than the third width W3. As an example, the first, second, and third widths W1, W2, W3 may be relatively constant between the top and bottom portions of the protrusions 124, 126 and the relief region 128. As another example, the 124, 126 and the relief region 128 may be tapered.
As an example, the first protrusion 124 may be disposed closer to the third vertical sidewall 116 than the relief region 128 and the second protrusion 126. The first protrusion 124 may include a top surface such as the first load-bearing surface 186 and the second protrusion 126 may include another top surface such as the second load-bearing surface 188. When the bin 122 is assembled to the inner liner 108, the first lip 156 may line along the load-bearing surfaces 186, 188 so that front and rear portions of the fourth vertical wall 134 are supported. Supporting the front and rear portions of the fourth vertical wall 134 may prevent inadvertent rocking or movement of the bin 122 with respect to the inner liner.
FIG. 5 illustrates a cross-sectional view of a portion of the bin 122 and inner liner 108 taken along the lines 5-5 in FIG. 3 . In one or more embodiments, a second protrusion 126′ may include a step 192 that may be configured to act as a stop so that as the bin 122 is assembled to the inner liner 108, a bottom portion of the fourth vertical wall 134 bottoms out on the step 192. The relief region 128 may be formed by a first inner edge 194 a of the first protrusion 124, a second inner edge 194 b and a third inner edge 194 c of the second protrusion 126′.
The first and third inner edges 194 a, 194 c may be spaced apart so that the retention protrusion 135 formed by the pair of vertical struts 138 may engage the first and third inner edges 194 a, 194 c to form a force-fit condition. The force fit condition may allow the bin 122 to be selectively attached and detached from the inner liner 108. The first and third inner edges 194 a, 194 c may engage the vertical struts 138 so that the bin 122 is fixed in a vertical direction and depth direction, extending towards and away from the in the inner surface 120. As another example, a gap may be formed between the
As previously mentioned, a number of horizontal struts 140 may extend between the vertical struts 138 and engage the relief notches 142 disposed in the relief region 128. Use of struts 138, 140, as opposed to a solid member, may allow the retention protrusion 135 to flex and prevent cracking or breaking of the retention protrusion 135 as the retention protrusion 135 is inserted and removed from the relief region 128. The horizontal struts 140 may engage edges of the relief notches to act against an upward force or lateral force applied to the bin 122. The horizontal struts 140 may also help stabilize the fourth vertical wall 134 and the bin 122 to prevent rattling of the bin 122 against the inner liner 108, caused by vibration of the refrigerator 100.
A bottom portion of the V-shaped cross-section may be formed by the second horizontal wall 158 a radii 194 may extend between the bottom portion and the third vertical sidewall 116. The radii 194 and a space disposed between the second horizontal wall 158 and the first and second protrusions 124, 126 may facilitate injection molding of the first and second protrusions 124, 126. As an example, the dashed lead lines may indicate material flow of the inner liner 108 material and insulation disposed between the inner liner 108 and the door skin 110.
FIG. 6 illustrates an exemplary bin assembly 200 according to one or more embodiments. As an example, the bin 200 may include a receptacle 202 formed by a first sidewall 206 and a second sidewall 208. The bin 200 may include a front sidewall 210 that may have a substantially planar shape and the second sidewall 208 may extend from the first sidewall 206 and terminate at the front sidewall 210. The receptacle 202 may include a bottom wall 204 that may be disposed above the second horizontal wall 170 and configured to lie along the food support surface 147. The receptacle 202 may be configured to store and separate some food or beverage items from others that are stored in the bin assembly 200. The bin assembly 200 is another example of a bin that may be detachably connected, and in turn exchangeable, to the inner liner 108.
FIG. 7 illustrates another exemplary bin assembly 212 according to another embodiment. In one or more embodiments, the enclosure portion 130 may include a top portion 166 and a bottom portion 168 arranged to form a Z-shaped cross-section. In other words, when the bin 122 is assembled to the inner liner 108, the top portion 166 may be spaced further away from the inner liner 108 than the bottom portion 168. The bin 212 may include a trim member such as a bezel 214. The bezel 214 may include a bottom arm 216 and a top arm 218 that may be spaced apart from one another to form an opening 220. The opening 220 may allow a user to view food or beverage items that are retained in the bin 212 by the enclosure portion 130 and the bezel 214. The bottom arm 216 may be connected to the top arm 218 by a medial portion 224 and a pair of curved portions 222, 226. The bottom arm 216 may include a rear wall 228 and a front wall 230 that may collectively sandwich the top portion 166 of the enclosure portion 130. As an example, the rear wall 228 may be substantially aligned with the bottom portion 168 of the enclosure portion 130.
While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention. Additionally, the features of various implementing embodiments may be combined to form further embodiments of the invention.
