  • Publication number: 20230384023
    Abstract: A refrigerator includes a door frame and a perimetric surface of an insulation door panel of a panel unit that are spaced apart from each other. A component receiving groove is provided between the door frame and the perimetric surface of the insulation door panel, so that an operation module is received in the component receiving groove. When the operation module is received in the component receiving groove, at least of a part of the operation module is arranged to face a front surface of the panel unit through a bezel portion constituting the front surface of the panel unit. Therefore, a space for installing the operation module such as a detection sensor or a touch sensor is provided to be sufficiently wide along an edge of a door.
