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.

Refrigerator

A method for controlling a refrigerator includes determining whether or not a defrosting initiation condition is satisfied with respect to an evaporator, if the defrosting initiation condition is satisfied, detecting a pressure differential using one differential pressure sensor for measuring the pressure differential between a first through hole, which is positioned between the evaporator and an inlet port having air flowing in from a storage chamber, and a second through hole which is positioned between the evaporator and a discharge port having air discharged to the storage chamber, and variably defrosting in accordance with the measured pressure differential.

Refrigerator and method for controlling refrigerator

A refrigerator may include a body formed with a storage space and a cooling module accommodating space; a cooling module disposed in the cooling module accommodating space and having a heat absorption part and a heat radiating part; a drawer supporter disposed inside the storage space; and a drawer supported by the drawer supporter, and the drawer supporter is formed with an inner passage through which cold air flowing from the heat absorption part passes, and the drawer supporter is formed with a plurality of cold air discharge ports through which cold air of the inner passage is discharged in an opposite direction. Therefore, it is possible to maximize the depth of the storage space in the front-rear direction while minimizing the number of parts, and cool the entire storage space evenly.

The present invention provides a control method of a refrigerator, comprising: a first defrosting step of defrosting an evaporator and terminating the defrosting when the evaporator reaches a first temperature; a step of detecting pressure difference by means of a differential pressure sensor for measuring pressure difference between a first thru-hole, disposed between the evaporator and an inlet through which air flows in from a storage compartment, and a second thru-hole disposed between the evaporator and an outlet through which the air is discharged into the storage compartment; and a second defrosting step of additionally defrosting the evaporator if the measured pressure difference is greater than a configured pressure.

A refrigerator includes a body including at least one storage compartment and a cooling module accommodating space, a door to open and close the storage compartment, and a cooling module accommodated in the cooling module accommodating space. The cooling module may include a heat radiating part, a heat absorption part, and a cooling module barrier to separate the heat radiating part and the heat absorption part. The heat radiating part may be disposed eccentrically on one of lateral sides of the cooling module and the heat absorption part may be disposed at a lateral side of the heat radiating part.

A refrigerator includes a cabinet, an evaporator, an evaporator cover module, and a cold air supply module configured to communicate with the evaporator cover module. The evaporator cover module includes a rear plate that has a planar shape and that defines the surface of the storage space, a first insulation member located at a rear surface of the rear plate, and a second insulation member spaced apart from the first insulation member and located at a front surface of the inner case. The first insulation member and the second insulation member define a heat-exchange space configured to accommodate the evaporator between the first insulation member and the second insulation member.

A method for controlling a refrigerator includes: a step for determining whether or not a defrosting initiation condition is satisfied with respect to an evaporator; a step for, if the defrosting initiation condition is satisfied, detecting a pressure differential by means of one differential pressure sensor for measuring the pressure differential between a first through hole, which is positioned between the evaporator and an inlet port having air flowing in from a storage chamber, and a second through hole which is positioned between the evaporator and a discharge port having air discharged to the storage chamber; and a defrosting step for variably defrosting in accordance with the measured pressure differential.

The resent invention provides a refrigerator comprising: a cabinet having a storage chamber; a door for opening and closing the storage chamber; a case having a discharge port through which air is discharged to the storage chamber; an evaporator provided inside the case and for supplying cold air by means of heat exchange with air; a fan installed on the discharge port and for generating the airflow discharging to the storage chamber the air which has been heat exchanged in the evaporator; and a differential pressure sensor having a first pipe, of which one end is positioned on a part where the air is withdrawn to the fan, and a second pipe of which one end is positioned on a part where the air is discharged from the fan.
