Abstract

The invention is directed to a baking oven door 2 and baking oven 1. A camera 10 is mounted inside the door 2 and coupled to a heat sink 8 constituting an outer cover of the door 2.

Claims

1. Baking oven door (2) adapted to be attached to a household or industrial type baking oven (1) and being adapted to close an opening (4) to a muffle (5) of the baking oven (1), the baking oven door (2) comprising an outer (8) and an inner wall (7) and at least one image recording device (10), wherein the at least one image recording device (10) is mounted inside the door (2) in between the outer (8) and inner wall (7) and is arranged and adapted to pick up images of the muffle (5) interior, and wherein at least a part of the outer side of the outer wall (8) comprises a heat sink which is thermally coupled to the image recording device (10).

2. Baking oven door (2) according to claim 1, wherein the heat sink is a flat, sheet-like thermal conductor (8), preferably at least partially constituting an outer cover of the baking oven door (2).

3. Baking oven door (2) according to claim 1, wherein the outer wall (8) and/or outer cover, in particular the thermal conductor, are/is opaque to a user of the baking oven (1).

4. Baking oven door (2) according to claim 2, wherein the thermal conductor (8) is made from metal, a metal alloy, ceramic and/or plastic, and/or the thermal conductor (8) comprises metal, metal alloy, ceramic and/or plastic particles and/or fibres embedded in a matrix.

5. Baking oven door (2) according to claim 1, wherein the inner wall (7) of the door (2) comprises an image recording window (13), wherein the inner wall (7) is preferably made from glass at least in the region of the image recording window (13).

6. Baking oven door (2) according to claim 1, further comprising at least one partition wall (9) arranged between the outer (8) and inner wall (7), wherein the image recording device (10) is preferably mounted in between the partition wall (9) and the outer wall (8), and the partition wall/walls (9) between the image recording device (10) and the inner wall (7) comprises/comprise a further image recording window (14), wherein the at least one partition wall (9) is preferably made from glass at least in the region of the further image recording window (14).

7. Baking oven door (2) according to claim 1, comprising at least one channel (15, 16), preferably running in vertical direction in normal use of the baking oven door (2), the channel (15, 16) being designed for guiding through a cooling medium, preferably a gaseous cooling medium.

8. Baking oven door (2) according to claim 7, wherein at least one channel (15, 16) is arranged at least one of between the inner wall (7) and an adjacent partition wall (9), between two adjacent partition walls (9), and the outer wall (8) and an adjacent partition wall (9).

9. Baking oven door (2) according to claim 1, wherein the image recording device (10) is coupled to a cooling element (11) which is arranged within the baking oven door (2) and which is thermally coupled, preferably in direct thermal contact, to the heat sink (8).

10. Baking oven door (2) according to claim 7, wherein at least one of the at least one channel (16) is arranged and designed such that a cooling medium passing through the channel (16) impinges the image recording device (10) and/or the cooling element (11).

11. Baking oven door (2) according to claim 1, wherein an insulation material (12) is provided at least one of in a space between the inner wall (7) and the outer wall (8), in a space between the inner wall (7) and an adjacent partition wall (9), in a space between adjacent partition walls (9) and in a space between the outer wall (8) and an adjacent partition wall (9), wherein the insulation material (12) has recesses adapted to the size of the image recording window (13) and/or further image recording window (14).

12. Baking oven door (2) according to claim 7, wherein at least one channel (15) passes through the insulation material (12), preferably on a side of the insulation material (12) facing towards the outer wall (8).

13. Baking oven door (2) according to claim 1, wherein at least the inner wall (7), and preferably at least one of the at least one partition wall (9) arranged between the image recording device (10) and the inner wall (7), are coated with an infra-red reflecting material on a side facing the muffle (5) in normal use of the baking oven door (2), at least in the region of the image recording window (13) and/or further image recording window (14).

14. Baking oven door (2) according to claim 1, wherein at least one of the inner wall (7), outer wall (8) and at least one partition wall (9), is coated with a non-reflecting optic material on a side facing towards the outer side of the baking oven door (2), at least in the region of the image recording window (13) and/or further image recording window (14).

15.
