FIELD OF THE INVENTIONThis application relates generally to a crisper storage bin for a refrigerator, and more particularly, a crisper storage bin having a monorail sliding assembly.
BACKGROUND OF THE INVENTIONConventional refrigeration applications, such as domestic refrigerators, typically have both a fresh food compartment and a freezer compartment. The fresh food compartment is where food items such as fruit, vegetables, and beverages are stored and the freezer compartment is where food items that are to be kept in a frozen condition are stored. The compartments are generally separated by a partition that is either vertically or horizontally oriented depending on the specific configuration of that refrigerator.
Generally, storage bins are located within the fresh food and freezer compartments in order to more efficiently organize and compartmentalize the items stored in said compartments. These storage bins often ride in a frame that suspends said storage bins above a bottom surface of a refrigerator liner.
Moreover, additional supports are often used to promote efficient and correct sliding of the storage bins between a retracted position and an extended position. For example, two or more rails secured to the bottom wall and/or opposing side walls of the storage bin can be used to guide the storage bin. Rollers can additionally be used to promote a smooth guiding surface. However, these additional supports add cost and complexity to the overall design of the storage bin guidance system.
BRIEF SUMMARY OF THE INVENTIONIn accordance with one aspect, there is provided a refrigerator comprising a cabinet and a liner defining a compartment within the cabinet. A storage bin is slidably disposed within the compartment at a location above a support surface; the storage bin includes a bottom wall. The refrigerator further includes a sliding assembly that permits the storage bin to slide with respect to the support surface.
The sliding assembly comprises a support bracket fixedly secured to the support surface. The support bracket includes an elongated channel comprising a bottom channel portion and opposing arm channel portions. A wheel guiding surface is located in the bottom channel portion. The slide assembly further includes a guide rail that extends downwards from and is centrally positioned on the bottom wall with respect to opposing side walls of the storage bin. The guide rail is located at least partially within the elongated channel of the support bracket. A wheel is rotatably fixed to the guide rail and rotates about a horizontal axis. The wheel engages the wheel guiding surface of the bottom channel portion.
In accordance with another aspect, there is provided a refrigerator comprising a cabinet and a liner defining a compartment within the cabinet. A storage bin is slidably disposed within the compartment at a location above a support surface; the storage bin includes a bottom wall. The refrigerator further includes a sliding assembly that permits the storage bin to slide with respect to the support surface.
The sliding assembly comprises a support bracket fixedly secured to the support surface. The support bracket includes an elongated channel having opposing arm channel portions, wherein arm guiding surfaces are located in the opposing arm channel portions, respectively. The slide assembly further includes a guide rail that extends downwards form the bottom wall of the storage bin in a vertical direction. The guide rail is located at a central position of the bottom wall of the storage bin with respect to opposing side walls of the storage bin and is at least partially disposed within the elongated channel of the support bracket.
The guide rail includes a connector member that is connected to and extends directly from the bottom wall of the storage bin. Opposing arm members extend outwards and away from the connector member in a horizontal direction with respect to the connector member. Each of the opposing arm members is disposed within the opposing arm channel portions, respectively, of the support bracket. The opposing arm members engage the arm guiding surfaces located in the opposing arm channel portions, respectively, to slidingly guide the storage bin between a retracted position and an extended position.
Referring now to the drawings,
As shown, the refrigerator 100 includes a structural outer cabinet 106 and a liner defining the fresh food and freezer compartments 102, 104 within the cabinet 106. The liner comprises a top surface 108a, a bottom surface 108b, a rear surface 108c, a first side surface 108d, and a second side surface 108e being parallel to the first side surface 108d and spaced therefrom via the rear surface 108c. As further shown, the fresh food and freezer compartments 102, 104 are vertically separated by a partition wall 110.
The freezer compartment 104 is selectively accessible via a freezer door 112 that is rotatably secured to the cabinet 106.
As further shown, multiple storage bins 122 are located within the fresh food compartment 102. These storage bins 122 are crisper bins capable of adjusting a degree of humidity within the storage bins 122. However, it is contemplated that the storage bins 122 discussed herein can function differently from crisper bins. That is, the storage bins 122 can be simple storage receptacles (i.e., not capable of adjusting a degree of humidity) or any other type of storage receptacles. The storage bins 122 are shown in a retracted position wherein said storage bins 122 do not inhibit the fresh food door 118 from closing to prevent access to the fresh food compartment 102. While
Moving on to
The storage bin 122 is slidably disposed within the fresh food compartment 102 at a location above a support surface 124 that is formed as part of the bottom surface 108b of the liner. That is, the storage bin 122 is located directly above the bottom surface 108b of the liner such that no intervening, separating structures (e.g., partitions, shelves, etc.) are disposed therebetween. As shown, the support surface 124 is recessed from the bottom surface 108b of the liner. In this manner, a gap between the storage bin 122 and the bottom surface 108b of the liner is minimized, thus promoting an aesthetically appealing appearance and providing an increased, such as a maximized, internal volume of the storage bin 122. Further, it is contemplated that the support surface 124 can be another surface such that the storage bin 122 is slidingly disposed at a location above a surface other than the bottom surface 108b of the liner. For example, the support surface 124 can be one of the storage shelves 120 within the fresh food compartment 102 or even the partition wall 110 such that the storage bin 122 is slidingly disposed within the freezer compartment 104.
As further shown, the refrigerator 100 includes a sliding assembly 126 that permits the storage bin 122 to slide with respect to the support surface 124. As shown, the storage bin 122 is supported only by the sliding assembly 126. That is, at any position between the retracted position to an extended position, the storage bin 122 is supported only by the sliding assembly 126 such that the storage bin 122 does not slide along the support surface 124 or any other structural support (e.g., rollers, guides, etc.). This configuration eliminates the need for additional guiding structures to promote efficient movement of the storage bin 122.
With respect to
A front end of the support bracket 128 includes horizontal alignment chamfers 133a formed in a top surface thereof. The horizontal alignment chamfers 133a are configured to promote correct alignment of the storage bin 122. Specifically, the horizontal alignment chamfers 133a provide self-alignment of storage bin 122 in the horizontal direction. Further, the support bracket 128 includes vertical alignment chamfers 133b provided on a bottom surface thereof. The vertical alignment chamfers 133b provide self-alignment of the storage bin 122 in the vertical direction. While the horizontal and vertical alignment chamfers 133a, 133b are shown as being angled edges, it is contemplated that the horizontal and vertical alignment chamfers 133a, 133b could alternatively be other geometric configurations (e.g., curved edges).
As shown in
Moreover, the support bracket 128 further includes detent members 144 that are disposed vertically above the elongated channel 134.

Moving on to
Moreover, the guide rail 154 further includes protrusions 160 extending outwards and away from the connector member 156 in a horizontal direction with respect to the connector member 156. Specifically, the protrusions 160 are oriented parallel to the opposing arm members 158. That is, the protrusions 160 likewise extend outwards toward the first and second side surfaces 108d, 108e of the liner, respectively. The protrusions 160 are disposed at a location between the bottom wall 150 of the storage bin 122 and the opposing arm members 158. Specifically, as will be further discussed below, each protrusion 160 is vertical positioned to engage with a respective detent member 144. Further, the protrusions 160 are positioned towards the rear wall 148 of the storage bin 122, such as shown in
The protrusions 160 are shown as being formed integrally with the connector member 156 (i.e., formed simultaneously during a molding operation). Alternatively, the protrusions 160 can be a separate and distinct element of the guide rail 154 such that the guide rail 154 is simultaneously formed with the storage bin 122 and then the protrusions 160 are secured to the connector member 156 (e.g., via fasteners, adhesives, etc.). In this manner, in the event that the protrusions 160 become deformed over time due to interaction with the detent members 144, as will be further discussed below, said deformed protrusions 160 can be removed and replaced. Furthermore, while

However, as previously mentioned, the detent members 144 are resilient arms. As such, when sufficient force is applied to the storage bin 122 in the extended direction (e.g., pulling the storage bin 122 outwards away from the rear surface 108c of the liner), the detent members 144 will deform (i.e., bend outwards and away from the protrusions 160 in a direction towards the first and second side surfaces 108d, 108e of the liner, respectively). As such, when the detent members 144 deform, they no longer prohibit the storage bin 122 from further extended movement. In other words, when sufficient force is applied to the storage bin 122 in the extended direction, the detent members 144 will deform outwards to allow the protrusions 160 to pass thereby and permit removal of the storage bin 122 from the fresh food compartment 102. Moreover, as shown in
In a separate embodiment, as shown in
In a further separate embodiment, the refrigerator appliance 100 includes a module 300 designed to hold goods on a door (e.g., the fresh food door 118) of the refrigerator 100. As shown in
In one embodiment, the holster 308 includes an enclosed, open loop to slidably receive the pitcher 306. Preferably, the pitcher 306 has a tapered design to easily be inserted into the enclosed loop of the holster 308. In other embodiments, the holster 308 can be sized to store other items (e.g., food containers, zip-top bags, dishware, etc.).
In yet another separate embodiment, the refrigerator 100 includes a capillary tube assembly used in the refrigerator's cooling system. In one embodiment, as shown in
The bi-stable valve 400 is controlled by an electronic control (not shown). Based on various operational conditions of the cooling system, the electronic control determines which outlet of the first and second outlet conduits 403, 405 of the bi-stable valve 400 is used. For example, based on the load or usage of the cooling system, the electronic control selects which outlet (i.e., the first outlet conduit 403 or the second outlet conduit 405) to circulate a cooling refrigerant therethrough.
The extended capillary tube 408 can selectively be placed in series with the main capillary tube 406 to increase the restriction in the cooling system thereby improving heat transfer in a condenser/liquid line. That is, a suction tube 410 is connected between the evaporator 404 and a compressor 412. A portion of the main capillary tube 406 and a portion of the suction tube 410 are placed in a heat exchanger 414 (i.e., in heat exchanging relationship with one another). The foregoing could be used during lighter heat load conditions, such as when the door of the refrigerator remains closed, fewer products are loaded in the refrigerator, or cooler ambient temperatures are present.
As further shown, an outlet of the compressor 412 is connected to an inlet of the condenser 416, and an outlet of the condenser 416 is connected to an inlet of the filter dryer 402. The cooling system further includes a low-pressure side and a high-pressure side, which are represented in the figures by separate dashed lines.
