Abstract
A vacuum adiabatic body according to the present invention includes a supporting block which is fastened to an outer surface of any one plate placed outside the control space in a plate member which provides a wall of the vacuum adiabatic body. Accordingly, since the vacuum adiabatic bodies in a state of being not in contact with each other can be fastened to each other, various products corresponding to the needs of the consumer can be provided.
Claims20
A vacuum adiabatic body comprising:
- a first plate of a first temperature;
- a second plate of a second temperature;
- a seal that seals the first plate and the second plate to provide a third space that has a third temperature and is in a vacuum state;
- at least one support in the third space;
- a support block that is fastened to an outer surface of the second plate, the support block having a recess;
- and
- a division panel provided in the recess and configured to divide the recess into a first recess in which a controller is received and a second recess in which a pipeline for at least one of a defrost water and an electric line path is received,
- wherein the second recess includes a through-hole in which part of the pipeline is to pass through.
