Abstract: 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.

Abstract: 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.
