A refrigerator is proposed. The refrigerator includes a refrigerating compartment, a freezing compartment, and an ice-making compartment. The refrigerating compartment is configured to receive cool air from a refrigerating compartment side grill fan assembly, and the ice-making compartment is configured to be located in any one refrigerating compartment door and to receive cool air from a freezing compartment side grill fan assembly with the freezing compartment. The refrigerating compartment side grill fan assembly is configured to supply a greater amount of cool air to a space at a refrigerating compartment door without the ice-making compartment than the amount of cool air supplied to other spaces, and the freezing compartment side grill fan assembly is configured to supply a greater amount of cool air to a space communicating with a recovery duct for the ice-making compartment than the amount of cool air supplied to other spaces.

A refrigerator include: an inner case having a storage chamber; a thermoelectric module including a thermoelectric element and a cooling sink; a fan configured to circulate air, to the storage chamber; a fan cover configured to cover the fan and having an upper discharge hole, a lower discharge hole, and an inner suction hole formed between the upper discharge hole and the lower discharge hole; a first receiving member disposed in the storage chamber; and a second receiving member disposed over the first receiving member to be spaced apart from the first receiving member. At least a portion of each of the inner suction hole and the lower discharge hole faces a portion between the first receiving member and the second receiving member, and at least a portion of the upper discharge hole faces a portion between a top surface of the storage chamber and the second receiving member.

The present invention discloses an air duct shielding device and an air-cooled refrigerator; the air duct shielding device includes: a fan base having a plurality of air outlets; a first adjusting part having a rotary disc portion and a plurality of first shielding sheets arranged at intervals, the first adjusting part being configured to controllably rotate around an axis of the rotary disc portion; and a second adjusting part provided between the first adjusting part and the fan base, the second adjusting part having a plurality of second shielding sheets arranged at intervals; wherein when the first adjusting part rotates around the axis of the rotary disc portion, the second adjusting part is driven to rotate, such that the first shielding sheet and/or the second shielding sheet completely shield(s), partially shield(s) or completely expose(s) each air outlet, thereby adjusting an air outlet area of each of the plural air outlets.

A refrigerator include: an inner case having a storage chamber; a thermoelectric module including a thermoelectric element and a cooling sink; a fan configured to circulate air, to the storage chamber; a fan cover configured to cover the fan and having an upper discharge hole, a lower discharge hole, and an inner suction hole formed between the upper discharge hole and the lower discharge hole; a first receiving member disposed in the storage chamber; and a second receiving member disposed over the first receiving member to be spaced apart from the first receiving member. At least a portion of each of the inner suction hole and the lower discharge hole faces a portion between the first receiving member and the second receiving member, and at least a portion of the upper discharge hole faces a portion between a top surface of the storage chamber and the second receiving member.

A refrigerator including a buffer unit for restrict heat transfer between a defrosting heater and an ice maker on the refrigerator. The defrosting heater is disposed at the evaporator and can remove frost on the evaporator. A cold air duct guides cold air generated by the evaporator to the ice maker during the cooling process. A cold air supply passageway is disposed below an ice making tray inside the ice maker. The buffer unit is coupled between the cold air duct and the cold air supply passageway. The buffer unit has a curved up inner surface which facilitates formation of a heat vortex therein, thereby effectively restricting heat transfer from the cold air duct to the ice maker during the defrosting process.

An aseptic ice making system includes an ice making system to receive water from a water supply. The ice making system includes an ice producing subsystem to produce ice and a positive air pressure subsystem to maintain a positive air pressure environment within the ice making system.

A supercooling refrigerator (1000) including: a refrigerator body (100); a door (200) for opening and closing one side of the refrigerator body (100); an accommodating portion (400) provided inside the refrigerator body (100) and seated with an object (M) to be stored; a cooling duct (600) including a fan for taking in air in the refrigerator body (100) and discharging the air, and an evaporator (630) for cooling the air discharged from the fan; and a cool air supply duct (700) formed with a cool air discharge port (710) through which the air cooled through the cooling duct (600) is discharged into the refrigerator body (100), the fan being a cross flow fan (620) including a plurality of discs (622), and a plurality of blades (623) disposed between the discs (622) along outer circumferential surfaces of the discs (622).

A rotation transmission mechanism may include a plurality of rotation transmission members having a drive wheel and a driven wheel, and an urging member which urges the driven wheel in a reverse direction to a rotational direction by power of the drive source. The drive wheel and the driven wheel are provided with engagement parts structured to transmit turning of the drive wheel to the driven wheel, the drive wheel is provided with a cam face forming part on which the engagement part of the driven wheel is slid at a rotational position where the engagement parts are not engaged with each other, and a brake member structured to generate a rotation load is disposed in a range on an upstream side of a power transmission path including the drive wheel with respect to the driven wheel in the power transmission path transmitting the power of the drive source.
