Abstract
Provided is a vacuum adiabatic body. The vacuum adiabatic body includes a mullion configured to divide the first space into two spaces and a connection pipe supported on the mullion so as to be fixed in position, the connection pipe being configured to connect the two space to each other. According to the embodiment, the vacuum adiabatic body may increase in strength, and also, a passing path of defrosting water may be secured.
Claims20
A refrigerator comprising:
- a vacuum adiabatic body that includes:
- a first plate;
- a second plate;
- a sheet that seals the first plate and the second plate, providing a vacuum space;
- and
- a support configured to maintain the vacuum space;
- a partition configured to divide an interior of the refrigerator into two spaces;
- a partition seating frame configured to support the partition and including a first part coupled to a first wall of the first plate and a second part coupled to a second wall of the second plate, the second wall extending in a direction different from an extending direction of the first wall;
- and
- a connection pipe extending through the partition and being fixed in position, the connection pipe being configured to fluidly connect the two spaces to each other,
- wherein the connection pipe has a groove into which at least one of the first part of the second part of the partition seating frame is inserted.

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 and is 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 that seals the first plate and the second plate, providing 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.
