Vacuum adiabatic body and refrigerator

A refrigerator comprising:

• a vacuum adiabatic body includes a first plate that defines at least a portion of a first side of a wall adjacent to a first space having a first temperature, a second plate that defines at least a portion of a second side of the wall adjacent to a second space having a second temperature, a thermal insulator that connects the first plate to the second plate to provide a third space which has a third temperature and is in a vacuum state, the thermal insulator is to reduce heat transfer between the first plate and the second plate, at least one support to the third space, and an opening that forms with respect to a storage space;
• a partition that divides the storage space into at least two spaces, the partition includes an adiabatic member to insulate the at least two spaces;
• a first door that opens and closes a first space of the at least two spaces;
• a second door that opens and closes a second space of the at least two spaces;
• an evaporator provided in the storage space;
• a machine chamber provided outside the storage space;
• a refrigerant pipe that connects the machine chamber and the evaporator;
• and
• a drain pipe that penetrates the vacuum adiabatic body to guide defrost water from the evaporator to outside of the vacuum adiabatic body,
• wherein a heat transfer rate of the adiabatic member in the partition higher than a heat transfer rate in the third space,
• wherein at least one of the defrost water and an electric line path penetrates the third space, and through-holes for pipelines are provided at the first plate and the second plate, and
• wherein a cold air flow path, provided through the partition, that sends and receives cold air between the first space and the second space of the at least two spaces.

A refrigerator comprising:

• a first plate that defines at least a portion of a first side of a wall adjacent to a first space having a first temperature;
• a second plate that defines at least a portion of a second side of the wall adjacent to a second space having a second temperature different;
• a thermal insulator that connects the first plate to the second plate to provide a third space which has a third temperature and is in a vacuum state, the thermal insulator is to reduce a heat transfer between the first plate and the second plate;
• at least one support in the third space;
• a main body having a cavity formed by the first plate and the second plate;
• a dividing wall fastened to the first plate so as to divide a space in the cavity into at least two spaces;
• at least one door that closes at least one of a first space or a second space of the at least two spaces;
• a gasket installed to the at least one door or the main body so as to seal a portion at which the door and the main body contact each other;
• and
• a sealing frame that contacts the gasket, and is provided between the third space and the gasket;
• wherein the dividing wall includes an adiabatic material having a thermal conductivity which is higher than a thermal conductivity in the third space.
