Abstract

Provided is a vacuum adiabatic body. The vacuum adiabatic body includes an alternating current line through which AC current flows as a driving source, a direct current line through which direct current flows as a driving source, and a signal line through which a control signal flows as electric lines configured to electrically connect the first space to the second space. Thus, the number of lines passing through the vacuum adiabatic body may be reduced.

First claim

The invention claimed is:

1. A vacuum adiabatic body, comprising:
a first plate;
a second plate;
a vacuum space provided between the first plate and the second plate;
an electric line configured to electrically connect a first space adjacent to the first plate and a second space adjacent to the second plate, the electric line being provided outside the vacuum space to allow the electric line not to pass through the vacuum space; and
a sealing frame comprising a first part provided in the first space, a second part provided in the second space, and a third part provided to shield edges of the first plate and the second plate to connect the first part with the second part,
wherein the first part includes a portion spaced apart from the first plate, and the third part includes a portion spaced apart from the edges of the first plate and the second plate, and
wherein the electric line comprises a first portion to pass through a first gap between the edges of the first plate and the second plate and the portion of the third part, and a second portion to pass through a second gap between the first part and the first plate, the second gap being connected to the first gap.

2. The vacuum adiabatic body of claim 1 , wherein the first portion is provided in the first space and the second portion is provided outside the edge of the first plate.

3. The vacuum adiabatic body of claim 1 , wherein the first portion is connected to the second portion.

4. The vacuum adiabatic body of the claim 1 , wherein the electric line extends in a space defined by the first plate and the second plate, and the sealing frame.

5. The vacuum adiabatic body of the claim 1 , wherein the electric line passes towards the second space from the first space via the first gap and the second gap.

6. The vacuum adiabatic body of the claim 1 ,
wherein the third part is bent from the first part and connects to the second part.

7. The vacuum adiabatic body of the claim 1 , further comprising a reinforcing frame mounted on the first plate,
wherein the electric line extends between the first part and the reinforcing frame.

8. The vacuum adiabatic body of the claim 1 , further comprising a reinforcing frame mounted on the first plate,
wherein the reinforcing frame comprises a slit through which the electric line passes.

9. The vacuum adiabatic body of the claim 1 , further comprising a component provided in one of the first space and the second space and a controller provided in the other of the first space and the second space,
wherein the electric line connects the component to the controller.

10. The vacuum adiabatic body of the claim 9 , wherein the first part of the sealing frame includes a seat on which the component is mounted,
wherein the component is disposed between the first plate and the first part of the sealing frame.

11. The vacuum adiabatic body of the claim 9 , further comprising an adiabatic member provided at edges of the first plate and the second plate,
wherein the electric line is positioned inside the adiabatic member.

12. A vacuum adiabatic body, comprising:
a first plate;
a second plate;
a vacuum space provided between the first plate and the second plate;
an electric line configured to electrically connect a first space adjacent to the first plate and a second space adjacent to the second plate; and
a sealing frame provided at edges of the first plate and the second plate and configured to cover a portion of the electric line, the sealing frame including a part provided in the first space; and
a reinforcing frame mounted on a surface of the first plate that faces the first space, the reinforcing frame being spaced apart from the part of the sealing frame,
wherein the electric line comprises a portion to pass through a first gap between the part of the sealing frame and the reinforcing frame.

13. The vacuum adiabatic body of the claim 12 , further comprising a second gap formed between the edges of the first plate and second plate and the sealing frame,
wherein the electric line passes the second gap.

14. The vacuum adiabatic body of the claim 12 , wherein the electric line extends toward the second space from the first space by detouring the vacuum space.

15. The vacuum adiabatic body of the claim 12 , further comprising a component provided in the first space and a controller provided in the second space, the component and the controller being connected to the electric line,
wherein the part of the sealing frame comprises a seat on which the component is mounted.
