The artificial intelligent food refrigerating device and method according to the present disclosure may be associated with an artificial intelligent module, a robot, an augmented reality (AR) device, a virtual reality (VR) device, a 5G service-related device, etc.

A first storage compartment's influence on a second storage compartment, when the first storage compartment and the second storage compartment have different temperature ranges and are cooled by a single cooler, is reduced. A refrigerator includes a compressor for compressing and circulating a refrigerant, a cooler provided to generate cold air through circulation of the refrigerant, a first storage compartment having an temperature maintained within a first range, a second storage compartment having an temperature maintained within a second range different from the first range, a first air passage for guiding cold air generated in the cooler to the first storage compartment, a second air passage for guiding cold air generated in the cooler to the second storage compartment, and a switching unit for guiding the cold air generated in the cooler to selectively flow into any one of the first air passage and the second air passage.

A refrigerator (1) includes a storage chamber (12) for produce storage and a produce ripening control system (10). The produce ripening control system (10) includes an ethylene absorber (18) adapted to operate in absorption mode in a first status and in desorption mode in a second status. A recirculation circuit (20) is configured to fluidly connect the absorber (18) with the storage chamber (12) and to draw air from the storage chamber (12), to flow the drawn air through the absorber (18) and to return it into the storage chamber (12). A control unit (30) configured to selectively operate the absorber either in the absorption mode for ethylene absorption or in the desorption mode for ethylene desorption.

A bottom mount refrigerator is provided with a pantry compartment that is accessible from outside the refrigerator by pulling open an easy access pantry drawer without the need to first open the fresh food compartment or the freezer compartment. A divider between the pantry compartment and the fresh food compartment is formed by a secondary mullion and a transparent shelf. The secondary mullion is provided with a light source for illuminating the contents of the pantry drawer. A light source at the rear of the pantry compartment shines generally forwardly and upwardly to illuminate the fresh food compartment.

A refrigeration device with a refrigerant circuit for cooling at least two cooling chambers. The device has a condenser of the refrigerant circuit configured to liquidize refrigerant, a compressor of the refrigerant circuit compresses refrigerant, a first evaporator of the refrigerant circuit cools a first cooling chamber of the refrigeration device, a second evaporator of the refrigerant circuit cools a second cooling chamber of the refrigeration device, and a multi suction line of the refrigerant circuit connects the condenser with the compressor. The first and second evaporators are positioned on the multi suction line in a consecutive order. The multi suction line has a first capillary tube, a second capillary tube, and a suction pipe. The first capillary tube connects the condenser with the first evaporator, the second capillary tube connects the condenser with the second evaporator, and the suction pipe connects the first and second evaporator with the compressor.

A refrigerator having a quick-freezing function includes: a main body; at least one freezing chamber disposed in the main body and comprising at least one quick-freezing chamber; a freezing evaporator disposed in the main body, and spaced apart from the at least one freezing chamber via a freezing air duct cover plate; a freezing fan corresponding to the at least one freezing chamber and a quick-freezing fan corresponding to the at least one quick-freezing chamber, and configured to blow cold air generated by the freezing evaporator into the at least one freezing chamber and the at least one quick-freezing chamber respectively; and a controller configured to control the freezing fan and the quick-freezing fan. The refrigerator can maintain the taste and nutrition of foods through quick-freezing, and prolong the fresh period of vegetables and fruits.

A refrigerator appliance includes a user interface, an environmental control system, a plurality of compartments disposed within the food storage chamber, each compartment of the plurality of compartments defining a food storage sub-chamber, at least one of the food storage sub-chambers having independently controlled environmental conditions, the independently controlled environmental conditions of the at least one food storage sub-chamber comprising temperature and humidity, at least one sensor associated with each food storage sub-chamber having independently controlled environmental conditions, and a controller in operative communication with the user interface, the environmental control system, and the at least one sensor, the controller operable to identify a food item, determine preferred environmental conditions for storage of the identified food item, and provide an indication of which of the food storage sub-chambers most closely matches the determined preferred storage conditions.
