Provided is a refrigerator, including a freezer compartment, a refrigeration compartment, a drying compartment, an air intake channel, a first sealing apparatus, and a second sealing apparatus. The drying compartment is independently provided within the refrigeration compartment in a sealed manner. The drying compartment is provided with an air inlet and an air outlet. The first sealing apparatus is provided in the drying compartment and can switch between sealing an air outlet of the air intake channel and leaving the air outlet of the air intake channel open. The second sealing apparatus is provided at the air outlet and can switch between sealing the air outlet and leaving the air outlet open. Cooled air in the freezer compartment is introduced into the drying compartment and then mixed with air in the drying compartment, a rise in the temperature of the cooled air allows the relative humidity in the drying compartment to be reduced.

The present invention provides a refrigerator comprising: a cabinet having a storage chamber; a door for opening or closing the storage chamber; a case in which an inlet through which air flows from the storage chamber and an outlet through which the air is discharged to the storage chamber are formed; an evaporator provided inside the case for exchanging heat with the air to supply cool air; and a differential pressure sensor provided inside the case.

An ice maker and method of operation for a refrigeration appliance, the ice maker including an ice maker frame having an air inlet provided at a first end thereof. An ice tray is rotatably secured to the ice maker frame and configured to form ice pieces therein. An air handler includes an outlet diffuser having a central body defined by a first wall-and a radially spaced apart second wall, wherein a plurality of radially extending fins are disposed between the first and second walls. Each of the fins is spaced apart, one from the other, along an outer peripheral surface of the first wall. In an installed position, the outlet diffuser is disposed directly adjacent the air inlet at the first end of the ice maker frame. A method is provided for synchronizing an ice making cycle of an ice making unit and a defrost cycle of an evaporator.

The present invention provides a refrigerator which shortens the time of passing through a maximum ice crystal generation zone by efficiently blowing cold air to an object to be frozen. With respect to the refrigerator according to the present invention, the upper portion of the upper freezing compartment is provided with: a first supply air duct for supplying cold air during normal cooling operation; and a second supply air duct for supplying cold air during rapid cooling operation. During rapid cooling operation, the blower is operated, and the cold air supplied from the supply air duct is supplied to the upper freezing compartment via the second supply air duct and the air outlet.

A refrigerator comprises: a refrigerator compartment comprising a storage compartment and a ventilation channel limited therein, wherein the ventilation channel is configured to provide a cold air to inside of the storage compartment; and a ventilation control device, arranged in the ventilation channel. The ventilation control device comprises: a housing comprising at least one air inlet and a plurality of air outlets; and an adjustment member configured to adjust respective areas of the plurality of air outlets, through which air is output, by being controlled to completely block, partially block, or completely open each of the air outlets, so as to adjust an air volume of the air output to the storage compartment via the ventilation channel.

A refrigerator to be installed in a storage space defined by a wall of an object includes a contact mechanism so that the refrigerator makes contact with the wall, and thus the refrigerator can be installed.

A refrigerator includes a cabinet that defines a storage chamber, a heat exchange space that is defined by the cabinet and positioned rearward of the storage chamber, an evaporator unit that is provided at the heat exchange space, a grill fan assembly that provides a barrier between the heat exchange space and the storage chamber, a drawer door that is configured to be inserted into and withdrawn out of the storage chamber, a draw-out rail provided between an inner surface of the lower storage chamber and both lateral sides of the drawer door to guide a movement of the drawer door into and out of the storage chamber, and a lighting unit provided at a rear surface of the door part and configured to illuminate the drawer part and to guide air coming from the outlet of the grill fan assembly in a downward direction into the storage space.

A method of making clear ice including filling an ice piece forming tray having an axis of rotation, a distal end, a motor engaging end, and plurality of ice piece making compartments with water. Freezing the water into ice by providing heat sinks disposed on and thermally connected to a bottom side of the ice piece forming tray. Removing heat from the plurality of heat sinks. Removing defrost water from the heat sinks by providing at least one defrost water channel along the axis of rotation, providing at least one defrost water channel along one of the distal end and the motor engaging end and connected to the defrost water channel along the axis of rotation. And delivering defrost water to a drain or defrost water catch tray positioned at one of the distal end and the motor engaging end.

The present invention provides a refrigerator comprising: a cabinet having a storage chamber; a door for opening or closing the storage chamber; a case in which an inlet through which air flows from the storage chamber and an outlet through which the air is discharged to the storage chamber are formed; an evaporator provided inside the case for exchanging heat with the air to supply cool air; and a differential pressure sensor provided inside the case.

A control method for a refrigerator comprises driving a first cooling fan to cool a first storage chamber; adjusting a damper to cause cold air to simultaneously flow through first and second cold-air passages; adjusting a damper to reduce the opening angle of the first cold-air passage, when the temperature of a high-temperature chamber reaches a value smaller than or equal to a second reference temperature for the high-temperature chamber; adjusting a damper to reduce the opening angle of the second cold-air passage, when the temperature of a low-temperature chamber reaches a value smaller than or equal to a second reference temperature for the low-temperature chamber; and driving a second cooling fan to cool a second storage chamber. When a predetermined time elapses or the sensed temperature of the high-temperature chamber reaches a first set temperature, the damper is adjusted to increase the opening angle of the first cold-air passage.
