A refrigerator includes a main body having a refrigerating compartment and a freezing compartment. A refrigerating compartment door is rotatably coupled to the main body to open and close at least a part of the refrigerating compartment, and includes an ice-making compartment and a dispenser. An auxiliary door opens and closes the ice-making compartment, and a cold air duct connects the ice-making compartment to the freezing compartment to cool the ice-making compartment. The ice-making compartment is formed on a front surface of the refrigerating compartment door such that access to the ice-making compartment is allowed via the auxiliary door with the refrigerating compartment door closed. The auxiliary door has an opening corresponding to the dispenser such an access to the dispenser is allowed with the auxiliary door closed.

A single-system air-cooled refrigerator, comprising a refrigerating compartment and a freezing compartment, wherein the refrigerator further comprises: a first air duct and a second air duct, which communicate the refrigerating compartment with the freezing compartment respectively; a first air door and a second air door which open and close the first air duct and the second air duct respectively; a refrigerating system; and a control system, configured to control opening and closing of the first air door and the second air door to implement a first working mode, a second working mode, or a third working mode of the refrigerator. The first working mode is that neither the freezing compartment nor the refrigerating compartment is switched, the second working mode is that the freezing compartment is switched to the refrigerating compartment, and the third working mode is that the refrigerating compartment is switched to the freezing compartment.

A refrigerator, comprising: a refrigerator body, an air duct assembly and a branched air supply apparatus; the air duct assembly has an accommodating cavity, air passages, and air supply ports opening forward; the air passages comprise a first air passage and a plurality of second air passages; the branched air supply apparatus is installed in the accommodating cavity and has a peripheral wall portion; the peripheral wall portion defines a plurality of air outlets, the plurality of air outlets comprising a first air outlet and a plurality of second air outlets; the first air passage is communicated with the first air outlet and a first storage space; each second air passage is communicated with one second air outlet and one or more air supply ports, and each of the second air outlets communicates with at least one second air passage.

A refrigerator including a cabinet including an insulator provided between an inner case and an outer case, a cold air duct embedded in the insulator to circulate cold air through the storage compartment, a cooling module mounting unit provided at a lower portion of the cabinet, and a cooling module including a module body in which an evaporator, a condenser, a compressor, and a cooling fan are installed and having an accommodating portion to accommodate the evaporator in a lying state, the cooling module being provided with a connection opening communicating with the cold air duct when mounted on the cooling module mounting unit.

Examples provide a smart maintenance cart for cleaning temperature-controlled display cases. The maintenance cart includes a main body including a set of water tanks, a pump, a vacuum, a set of hoses, a drain hose filter, a set of rollers, a memory, and a processor. A smart maintenance controller analyzes the sensor data using a set of per-case, customized performance thresholds. The smart maintenance controller generates a set of priority rankings for a set of temperature-controlled display cases based on a result of the analysis of the sensor data. The smart maintenance controller identifies a highest priority case in the set of temperature-controlled display cases for maintenance based on the set of priority rankings. The smart maintenance controller outputs a maintenance task notification to a user, the maintenance task notification comprising a case identifier associated with the highest priority case for cleaning.

Provided is a vacuum adiabatic body. The vacuum adiabatic body includes a mullion configured to divide a space within the refrigerator into a refrigerating compartment and a freezing compartment, an ice maker placed in the freezing compartment, and an ice-making cool air passage passing through the mullion to connect the freezing compartment to the ice maker. Therefore, cool air may be supplied in an adiabatic state to the ice maker disposed in the refrigerating compartment.

The present disclosure provides an air duct assembly of a refrigerator, comprising: a main body, the main body being provided with an air inlet toward one side of the main body, a plurality of air outlets formed in areas of two sides of the main body, and an air-uniformizing partition plate provided on the main body and located above the air inlet, and the air-uniformizing partition plate divides the air entered from the air inlet into the areas of two sides of the main body and the air is discharged via the plurality of air outlets.

An air volume adjustment device for a refrigerator comprises a fan, a baffle, an operating knob and a potentiometer. The baffle is disposed between a first air inlet cavity of a first compartment and a second air inlet cavity of a second compartment. The baffle is capable of moving among a plurality of positions to adjust the volume of air entering the first air inlet cavity and the second air inlet cavity. The operating knob and the potentiometer are connected to the front side and the rear side of the baffle respectively. The potentiometer is connected to a controller. The operating knob operably drives the baffle to move. The potentiometer transmits an electrical signal corresponding to a position of the baffle to the controller. The controller controls a rotational speed of the fan or controls the compressor to be started up or shut down.

An air supply assembly for a refrigerator, includes: an air duct cover plate defining, together with a refrigerator liner, an air supply space and configured to isolate the air supply space from a storage space in a compartment of the refrigerator, and a centrifugal wind wheel arranged in the air supply space, and axially sucking air in and blowing the air out towards a peripheral side, wherein a plurality of air return ports are provided in the air duct cover plate to allow air in the storage space to enter the air supply space; and the centrifugal wind wheel abuts against an inner side of the air duct cover plate and is configured to suck air in from a rear side thereof, such that air entering the air supply space via the air return ports is sucked in from the rear side of the centrifugal wind wheel.
