That is, the gasket body portion (221) can be positioned to surround the die portion (2122) from the outside.

[0069] Below, the shape of the first insulating member (218) will be described.

[0070] According to one embodiment, a first insulating member (218) may include a first vacuum insulating member (216) and a first foam insulating member (217) disposed around the first vacuum insulating member (216). The heat transfer coefficient of the first vacuum insulating member (216) may be lower than the heat transfer coefficient of the first foam insulating member (217).

[0071] The first vacuum insulation unit (216) may be configured as a vacuum insulation panel (VIP). The vacuum insulation panel is a type of insulation material that utilizes the low thermal conductivity characteristics of vacuum by forming a state close to vacuum by depressurizing the internal space. Here, "vacuum" does not mean a complete vacuum state, but rather a state of reduced pressure close to vacuum.

[0072] In one embodiment, the first vacuum insulation unit (216) may be implemented in the form of a panel having a predetermined thickness. For example, the first vacuum insulation unit (216) may have a rectangular parallelepiped shape. The first vacuum insulation unit (216) may be provided in the form of a panel that is positioned between the first front panel (211) and the first door liner (212).

[0073] The upper end of the first vacuum insulation part (216) may be in contact with the gasket joint part (222) of the first door gasket (22). For example, the upper end of the first vacuum insulation part (216) may be in contact with the gasket joint part (222) arranged on the upper end of the die part (2122). The upper end of the first vacuum insulation part (216) may be restrained by the gasket joint part (222) arranged on the upper end of the die part (2122).

[0074] The lower end of the first vacuum insulation part (216) may be in contact with the gasket joint part (222) of the first door gasket (22). For example, the lower end of the first vacuum insulation part (216) may be in contact with the gasket joint part (222) arranged at the lower end of the die part (2122). The lower end of the first vacuum insulation part (216) may be restrained by the gasket joint part (222) arranged at the lower end of the die part (2122).

[0075] One end of the first vacuum insulation part (216) may be in contact with the gasket joint part (222) of the first door gasket (22). For example, one end of the first vacuum insulation part (216) may be in contact with the gasket joint part (222) arranged on one side of the die part (2122). One end of the first vacuum insulation part (216) may be restrained by the gasket joint part (222) arranged on one side of the die part (2122).

[0076] The other end of the first vacuum insulation part (216) may be in contact with the gasket joint part (222) of the first door gasket (22). For example, the other end of the first vacuum insulation part (216) may be in contact with the gasket joint part (222) arranged on the other side of the die part (2122). The other end of the first vacuum insulation part (216) may be restrained by the gasket joint part (222) arranged on the other side of the die part (2122).

[0077] The first vacuum insulation unit (216) may be positioned between the first front panel (211) and the first door liner (212). The first vacuum insulation unit (216) may be in contact with the first front panel (211) and the first door liner (212). For example, the front side of the first vacuum insulation unit (216) may be in contact with the rear side of the first front panel (211), and the rear side of the first vacuum insulation unit (216) may be in contact with the front side of the first door liner (212).

[0078] Meanwhile, the first vacuum insulation part (216) may include an outer skin part that forms a predetermined space inside, and a core part that is accommodated inside the outer skin part and forms a predetermined space inside the outer skin part.

[0079] For example, the outer skin may be configured as a film in which a multilayer polymer and aluminum are laminated to maintain the internal vacuum level of the first vacuum insulation part (216) at a constant level.

[0080] The above core part may be composed of a glass fiber or silica core, etc., called glass fiber.

[0081] Additionally, the first vacuum insulation unit (216) may further include a getter for absorbing gas within the outer shell. The getter may be provided to absorb gas and / or moisture remaining or newly introduced within the outer shell.

[0082] The first foam insulation (217) can be placed in an insulation space (20a) defined by the first front panel (211), the first door liner (212), the first upper cap deco (213), the first lower cap deco (214), and the first side deco (215). For example, the first foam insulation (217) can be placed in the insulation space (20a) to surround the first vacuum insulation (216). That is, the first foam insulation (217) can be placed by foaming in the empty space remaining after the first vacuum insulation (216) is placed in the insulation space (20a). For example, the first foam insulation (217) can be composed of polyurethane foam.
