Vacuum adiabatic body and refrigerator

A refrigerator comprising:

• a main body having an internal space configured to store items;
• and
• a door to open or close the main body to allow access to the internal space,
• wherein at least one of the door or the main body comprises a vacuum adiabatic body, the vacuum adiabatic body including:
• a first plate;
• a second plate;
• a vacuum space provided between the first plate and the second plate;
• a support configured to maintain a distance between the first and second plates, the support being disposed next to or adjacent to the first plate,
• wherein the support includes:
• a first support plate configured to support the first plate;
• a second support plate configured to support the second plate;
• a plurality of coupling mechanisms configured to maintain a distance between the first support plate and the second support plate and secure the first support plate and the second support plate to each other;
• and
• a plurality of seating mechanisms configured to add structural rigidity to the support and maintain an alignment of the first and second plates.

A vacuum adiabatic body comprising:

• a first plate
• a second plate;
• a vacuum space provided between the first plate and the second plate;
• a support configured to maintain a distance between the first plate and the second plate, the support being disposed next to or adjacent to the first plate and including:
• a first support plate in contact with the first plate in the space, the first support plate including a plurality of bars protruding in the first direction;
• and
• a second support plate in contact with the second plate in the space, the second support plate having a plurality of recesses,
• wherein the recesses include a set of first recesses having a first width and a set of second recesses having a second width different from the first width.

A vacuum adiabatic body comprising:

• a first plate
• a second plate;
• a vacuum space provided between the first plate and the second plate;
• a support configured to maintain a distance between the first and second plates, the support being disposed next to or adjacent to the first plate, including:
• a first support plate configured to support the first plate;
• a second support plate configured to support the second plate;
• at least one coupling mechanism configured to secure the first support plate to the second support plate at at least one position;
• and
• a plurality of seating mechanisms configured to maintain a distance between the first support plate and the second support plate,
• wherein the seating mechanisms do not secure the first and second support plates to each other, and
• wherein the at least one coupling mechanism includes:
• a pressing opening provided in the second support plate;
• a coupling boss provided on the first support plate;
• and
• a coupling bolt configured to have a first end inserted into and supported by an inner surface of the pressing opening and a second end coupled to the coupling boss.
