A thermal insulation backpack enabling a rapid reduction in temperature without removing a product arranged therein and achieving a thermal insulation effect, and an operation method thereof. The thermal insulation backpack comprises a main body (10) and one or more adapter assembly (30). The main body (10) is provided with a thermal insulation accommodation cavity (102) therein, and provided with a connection hole (101) in communication with the thermal insulation accommodation cavity (102). The adapter assembly (30) is inserted into the connection hole (101), and comprises a fixing frame, a sealing screen (32), and a reset assembly. An outer periphery of the sealing screen (32) is provided with a sealing strip (321) protruding outward. A connection recess (316) and a first through slot (312) are provided in the fixing frame. The first through slot (312) is connected to the thermal insulation accommodation cavity (102). The sealing screen (32) is connected to the reset assembly. When the adapter assembly (30) is connected to an external cooling apparatus, the sealing screen (32) moves toward a direction of an interior of the thermal insulation accommodation cavity (102), such that the connection recess (316) is communicated with the first through slot (312). When the adapter assembly (30) is not connected to an external cooling apparatus, the sealing strip (321) presses against a lower end of the connection recess (316), such that the connection recess (316) is not communicated with the first through slot (312).

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 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 movable controlled atmosphere store for fruits and vegetables, including: a store body in rectangular container structure and successively provided with an equipment room and a storage room along length direction; the equipment room is provided with an equipment door respectively on left and right sides; the storage room is in thermal insulation and sealing structure and provided with a sealing door at an end far away from the equipment room, and is provided with a sampling door on a side which is provided with a sealing film connected around a frame thereof, and a sampling assembly connected with the sealing film in cylindrical structure; a controlled atmosphere control system, including a control panel, as well as a refrigerator, a humidifier, a sterilizer, a nitrogen generator, a carbon dioxide adsorber, an ethylene adsorber, a temperature and humidity sensor and a gas concentration sensing device connected with the control panel.
