Vacuum adiabatic body and refrigerator

A refrigerator comprising:

• a first accommodation space in which an evaporator is provided along a rear surface thereof, the first accommodation space being defined by a vacuum adiabatic body;
• a second accommodation space configured to receive cool air from the first accommodation space;
• and
• a pipe configured to guide air in the second accommodation space toward the evaporator,
• wherein the pipe includes:
• a head having a suction hole that is opened to the second accommodation space to receive the air;
• a vertical transfer duct extending vertically from a side of the evaporator to transfer the air in a vertical direction;
• a side transfer duct extending laterally from a lower region of the vertical transfer duct to transfer the air in a lateral direction;
• and
• a rear discharge hole defined in a rear surface of the side transfer duct to discharge the air backward toward the evaporator.

A refrigerator comprising:

• a first accommodation space in which an evaporator is disposed along a rear thereof;
• a second accommodation space;
• a partition configured to separate the first accommodation space from the second accommodation space;
• a fan provided at one side of the evaporator;
• a discharge pipe extending from the first accommodation space toward the second accommodation space;
• and
• a collection pipe extending from the second accommodation space toward the first accommodation space,
• wherein:
• air cooled by the evaporator is transferred to the discharge pipe by the fan,
• the cooled air moves along the discharge pipe to pass through the partition and to be received at a lower end of a passage guide of the second accommodation space,
• the cooled air moves along the passage guide and is discharged into the second accommodation space,
• air from the second accommodation space is received by the collection pipe so as to be guided toward the evaporator, and
• at least a portion of the first accommodation space is defined by a vacuum adiabatic body,
• wherein the vacuum adiabatic body includes:
• a first plate;
• a second plate;
• a sheet configured to seal between the first plate and the second plate so as to provide a vacuum space;
• and
• a support configured to maintain the vacuum space;
• wherein the collection pipe includes:
• a head having a suction hole that is opened to the second accommodation space to receive air;
• a vertical transfer duct positioned on a side surface inside the first accommodation space, the vertical transfer duct extending vertically;
• a side transfer duct extending laterally from a lower portion of the vertical transfer duct;
• and
• a rear discharge hole defined in a rear surface of the side transfer duct to discharge air toward the evaporator.
