Abstract

Provided is a vacuum adiabatic body. The vacuum adiabatic body includes a mullion configured to divide a space within the refrigerator into a refrigerating compartment and a freezing compartment, an ice maker placed in the freezing compartment, and an ice-making cool air passage passing through the mullion to connect the freezing compartment to the ice maker. Therefore, cool air may be supplied in an adiabatic state to the ice maker disposed in the refrigerating compartment.

Claims (46)

1. A refrigerator comprising:

a vacuum adiabatic body including:

a first plate configured to provide at least a portion of a wall defining a space within the refrigerator;

a second plate configured to provide at least a portion of an outer wall of the refrigerator;

a sheet configured to seal the first plate and the second plate so as to provide a vacuum space between the first plate and the second plate;

a partition configured to divide the space within the refrigerator into a refrigerating compartment and a freezing compartment;

an ice maker positioned away from the freezing compartment; and

at least one air passage passing through the partition to fluidly connect the freezing compartment to the ice maker.

2. The refrigerator according to claim 1 , wherein the air passage extends along the first plate.

3. The refrigerator according to claim 1 , wherein the air passage extends along the partition.

4. The refrigerator according to claim 3 , wherein a portion of the air passage is accommodated in the partition.

5. The refrigerator according to claim 1 , wherein the air passage has a cross-section that extends further in a first direction than in a second direction.

6. A refrigerator comprising:

a vacuum adiabatic body including a freezing compartment and a refrigerating compartment;

a partition configured to separate the refrigerating compartment from the freezing compartment;

an evaporator positioned in the freezing compartment to generate cool air;

a door configured to open and close the refrigerating compartment;

an ice maker positioned in the door; and

an air passage that is provided within the refrigerating compartment and passes through the partition to guide the cool air generated in the evaporator toward the ice maker.

7. The refrigerator according to claim 6 , further comprising a side panel provided at a wall of the refrigerating compartment,

wherein the air passage is accommodated in the side panel of the refrigerating compartment.

8. The refrigerator according to claim 7 , wherein a side panel adiabatic material is configured to surround at least a portion of the air passage in the side panel.

9. The refrigerator according to claim 8 , wherein the side panel adiabatic material is a foamed material.

10. The refrigerator according to claim 8 , wherein the partition includes a partition panel and a partition adiabatic material provided in the partition panel.

11. The refrigerator according to claim 10 , wherein the partition adiabatic material and the side panel adiabatic material are a foamed material.

12. The refrigerator according to claim 6 , wherein the air passage is a first air passage; and

wherein the refrigerator further comprises a second air passage configured to return air from the ice maker toward the evaporator.

13. The refrigerator according to claim 6 , wherein the air passage is connected to a door-side air passage in the door and having an opening on a side surface of the door.

14. The refrigerator according to claim 6 , wherein the air passage is connected to a door-side air passage in the door and having an opening on a bottom surface of the door.

15. The refrigerator according to claim 14 , wherein a gate is provided at a connection of the air passage and the door-side air passage.

16. The refrigerator according to claim 6 , wherein the vacuum adiabatic body includes:

a first plate configured to define at least a portion of a wall for the accommodation space;

a second plate configured to define at least a portion of an outer wall;

a sheet configured to seal the first plate and the second plate so as to provide a vacuum space between the first plate and the second plate; and

a support configured to maintain the vacuum space.

17. The refrigerator according to claim 6 , wherein the door includes a vacuum adiabatic module, and

the vacuum adiabatic module is configured to form at least portion of a front surface and a side surface of the door.

18. The refrigerator according to claim 17 , wherein the vacuum adiabatic module includes an opening for a dispenser provided on front surface of the door.

19. A refrigerator comprising:

a first body having a first opening to access a freezing space, the first body including a first vacuum adiabatic body having a first vacuum space;

a first door configured to open and close the first opening of the first body;

a second body having a second opening to access a refrigerating space, the second body including a second vacuum adiabatic body having a second vacuum space;

a second door configured to open and close the second opening of the second body;

an ice maker provided in the second door; and

an air passage configured to pass through an adiabatic portion of a boundary between the first vacuum adiabatic body and the second vacuum adiabatic body so as to guide cool air of the freezing space toward the ice maker.

20. The refrigerator according to claim 19 , wherein the first vacuum space of the first vacuum adiabatic body and the second vacuum space of the second vacuum adiabatic body communicate with each other.
