A refrigerator shelving system includes an upper shelf, suspenders, rails, and a lower shelf. The upper shelf has nests disposed along a bottom side of the upper shelf. The suspenders are rotatably secured to the upper shelf. The rails are suspended from the upper shelf via the suspenders. The lower shelf is slidably secured to the rails and has bosses extending laterally outward therefrom. Each of the bosses are configured to engage one of the nests to maintain the lower shelf in a stowed position. The lower shelf is configured to slide forward from the stowed position to an intermediate position via the rails to disengage the bosses from the nests. The lower shelf is configured to rotate downward and rearward via the suspenders to transition from the intermediate position to an operational position.

The present invention aims at providing a low-temperature storage container that is highly insulated and can therefore reduce the amount of cooling medium consumption. The low-temperature storage container of the present invention includes a cylindrical container body having an opening and a storage compartment, and a plurality of holding shelves provided in the storage compartment, on which storage trays for holding storage objects are placed. The storage compartment includes a plurality of holding zones arranged in a circumferential direction of the container body, where the storage trays are held, and at least one passage zone where the storage trays pass. The holding shelves are configured as parts of a plurality of rack units that are sections arranged in a circumferential direction of the container body.

An engagement assembly, a drawer, and a refrigerator having same. The engagement assembly comprises a first engagement part matching the drawer and a second engagement part matching a refrigerator body; one of the first and second engagement parts is a gear, and the other one is a rack; the rack has a tooth surface that allows the gear to travel; the rack comprises a main rack and an extension rack; when the drawer is in a closed state, the tooth surface has a first stroke length; when the drawer is in an opening process, the extension rack moves to a travel path of the gear so that the tooth surface has a second stroke length; when the drawer is in a closing process, the extension rack is reset; the first stroke length is smaller than the second stroke length. The length of the tooth surface increases in the opening process.

A refrigerator appliance includes a storage compartment having a storage drawer assembly disposed therein. The storage drawer assembly includes a carrier drawer, a lid, and a bin that may be reversibly mounted in the carrier drawer in either a first orientation or in a second orientation. The bin defines a storage space for receiving food items. The bin includes a sealing wall that encloses the storage space in the first orientation. The bin defines an access opening that grants access to the storage space in the second orientation.

Methods of operating a refrigerator appliance are provided. The refrigerator appliance includes a cabinet defining a food storage chamber with a drawer slidably mounted within the food storage chamber. The refrigerator appliance also includes a sensor operable to detect an atmospheric condition within the food storage chamber of the drawer and a camera assembly positioned and configured for monitoring the drawer. The methods generally include obtaining an image using the camera assembly and analyzing the image to identify a first food item and a second food item in the food storage chamber of the drawer.

A refrigerator includes a cabinet and a shelf. The cabinet has a rear wall and opposing side walls extending forward from the rear wall. The rear wall and opposing side walls define an internal cavity. The shelf is disposed within the internal cavity, has a base portion defining a plurality of aligned grooves, and has an extendable portion having a plurality of aligned protrusions. Each protrusion is disposed and slidable within one of the aligned grooves. The extendable portion is configured to transition between first and second positions relative to the base portion via sliding the plurality of aligned protrusions within the plurality of aligned grooves.

A detection system for estimating a weight of one or more items in a refrigerator is disclosed. The system comprises at least one shelf; at least one transducer configured to transmit a sonic or ultrasonic wave into the at least one shelf and capture the reflected or refracted wave from the shelf; and a processor configured to estimate the weight of the one or more items on the shelf from the sonic or ultrasonic wave received from the at least one transducer. The system further comprises a plurality of cameras configured to capture images of the one or more items on the shelf. The cameras are configured to capture images of the items while on the shelf and off the shelf, which are then used to identify the items and the changes in weight of those items. Items may be automatically reorder based on their weight or change in weight.

A refrigerator drawer includes a front wall, a rear wall, first and second opposing sides walls, an adjustable partition wall, and first and second rollers. The front and rear walls define first and second slots, respectively. The first and second opposing sides walls each extend between the front and rear walls such that the front, rear wall, and side walls define an internal storage space. The partition wall is disposed within the storage space. The partition wall has first and second ends extending outward and through the first and second slots, respectively. The first and second rollers are attached to the first and second ends on opposing sides of the front and rear walls, respectively. The first and second rollers are configured to roll along exterior surfaces of the front wall and rear wall, respectively, to adjust distances between the partition wall and the side walls.

A refrigerator includes a crisper drawer, a frame, and a cover plate. The frame is configured to receive the crisper drawer. The frame defines at least one orifice that is configured to vent air from the crisper drawer to an exterior of the crisper drawer to control a humidity within the crisper drawer. The cover plate is secured to the frame and is at least partially disposed over the at least one orifice. The cover plate is configured to pivot relative to the frame between a first position and a second position. The cover plate restricts air flow out of the crisper drawer in the first position. The cover plate facilitates air flow out of the crisper drawer in the second position.

A drawer-shelf system for a refrigerator includes a drawer, a support rail, and a shelf plate. The drawer has a ridge protruding therefrom. The support rail defines a first channel along a side of the support rail. The first channel is configured to receive the ridge such that the drawer is slidable relative to and supported by the support rail. The support rail has a protrusion extending upward from a first end of the support rail. The protrusion defines a second channel. The shelf plate has an outer edge extending about an outer periphery of the shelf. A first portion of the outer edge is configured to be disposed within the second channel such that the shelf plate is supported by the first end.
