Abstract

An oven includes a main body having a cooking room, a door disposed in the main body to open or close the cooking room, a door having a window to view the inside of the cooking room, a light emitting member disposed in the door, and a guide member to guide light of the light emitting member toward the cooking room.

First claim

What is claimed is:

1. An oven comprising:
a main body having a cooking compartment;
a door configured to open and close, and thereby open and close, respectively, the cooking compartment; and
a light emitting member disposed at the door,
wherein the door includes:
a window configured to provide a view of an inside of the cooking compartment from an outside of the cooking compartment when the door is closed; and
a guide member configured to guide the emitted light from the light emitting member toward the inside of the cooking compartment, and

wherein the oven further includes at least one of the following:
the guide member includes a curved section,
the door further includes a handle, and the light emitting member is disposed inside the handle, and
the light emitting member is provided on an outer surface of the door.

2. The oven of claim 1 , wherein the light emitting member and the guide member are disposed at at least one of a left side, a right side, an upper side and a lower side of the window.

3. The oven of claim 1 , wherein the light emitting member and the guide member are disposed at at least one of a lower portion of a left side, an upper portion of the left side, a lower portion of a right side and an upper portion of the right side of the window.

4. The oven of claim 1 , wherein the light emitting member and the guide member are disposed on at least one of a left portion of an upper side, a right portion of the upper side, a left portion of a lower side and a right portion of the lower side of the window.

5. The oven of claim 1 , wherein the guide member includes at least one of a solid member configured to guide the emitted light from the light emitting member and a hollow member configured to guide the emitted light from the light emitting member.

6. The oven of claim 5 , wherein the hollow member includes a reflecting surface configured to transmit the emitted light from the light emitting member from an incident end of the hollow member to an emitting end of the hollow member.

7. The oven of claim 1 , wherein the guide member includes a first portion extending in a first direction from an incident surface of the guide member, and a second portion bent relative to the first portion and extending in a second direction different from the first direction.

8. The oven of claim 1 , wherein the guide member includes a straight section.

9. The oven of claim 1 , wherein the light emitting member includes a printed circuit board including a light emitting element,
wherein the printed circuit board is provided perpendicular to an incident surface of the guide member.

10. The oven of claim 9 , wherein the printed circuit board is provided parallel to the window.

11. The oven of claim 9 , wherein the printed circuit board is provided perpendicular to the window.

12. The oven of claim 1 , wherein the guide member is disposed parallel to the window, and the guide member includes a reflecting surface formed to at least one of refract and reflect the light emitted from the light emitting member toward the cooking compartment.

13. The oven of claim 1 , wherein at least one of an incident surface and an emitting surface of the guide member includes at least one of a flat surface, an inclined surface, a convex surface, and a concave surface.

14. The oven of claim 1 , wherein an emitting surface of the guide member includes at least one of an irregular bumpy surface, a regular bumpy surface, and a printed surface.

15. The oven of claim 1 , wherein the guide member includes a reflecting plate configured to reflect the light emitted from the light emitting member toward the cooking compartment.

16. The oven of claim 1 , wherein the light emitting member is detachably provided on an outer surface of the window relative to the cooking compartment.

17. An oven comprising:
a main body having a cooking compartment;
a door configured to open and close, and thereby open and close, respectively, the cooking compartment; and
a light emitting member disposed at the door and configured to emit light to an inside of the cooking compartment,
wherein the door includes:
a window configured to provide a view of the inside of the cooking compartment from an outside of the cooking compartment when the door is closed; and a panel forming the window, the panel including a guide portion provided on one surface of the panel by a printing method or a coating method to guide the light emitted from the light emitting member toward the inside of the cooking compartment.

18. The oven of claim 17 , wherein the light emitting member is disposed on at least one of the a left side, a right side, an upper side, and a lower side of the panel, and
the guide portion includes a reflecting surface configured to refract the light entered into the panel from the light emitting member toward the inside of the cooking compartment.

19. The oven of claim 18 , wherein the reflecting surface includes at least one of an irregular bumpy surface, a regular bumpy surface, and a printed surface.

20. The oven of claim 18 , wherein the reflecting surface is provided on one side of the panel corresponding to the side on which the light emitting member is disposed.

21. The oven of claim 17 , wherein the guide portion includes an anti-reflective coating portion configured to transmit the emitted light from the light emitting member without reflecting the light.

22. The oven of claim 21 , wherein the door further includes a handle disposed on the outer portion of the door,
the light emitting member is disposed inside the handle, and
the light emitted by the light emitting member passes through the anti-reflective coating portion to be guided to the inside of the cooking compartment.

23. The oven of claim 21 , wherein the panel includes a plurality of guide portions,
the light emitting member is disposed in an illuminating device configured to be detachably attached on the panel, and
the illuminating device is attached at a position corresponding to one guide portion of the plurality of guide portions, and configured to emit light toward the inside of the cooking compartment.

24. The oven of claim 23 , wherein the illuminating device includes:
a power supply configured to supply electric power to the light emitting member; and
a transceiver configured to exchange signals with the main body.

25. The oven of claim 17 , wherein the door includes a fan configured to cool heat generated by the light emitting member.

26. The oven of claim 25 , wherein the light emitting member includes a light emitting element, a printed circuit board on which the light emitting element is mounted, and a heat dissipating board attached on a rear surface of the printed circuit board.

27. The oven of claim 17 , wherein the light emitting member is disposed to be directly attached on the panel.

28. An oven comprising:
a main body having a cooking compartment;
a door configured to open and close, and thereby open and close, respectively, the cooking compartment; and
a light emitting member disposed at the door and configured to emit light to an inside of the cooking compartment,
wherein the door includes:
a plurality of panels configured to provide a view of the inside of the cooking compartment from an outside of the cooking compartment when the door is closed; and
an internal structure configured to s
