## Abstract

A household cooking appliance includes a cooking chamber delimited by a cooking chamber wall, and a cooking chamber camera located outside of the cooking chamber, for capturing an image from the cooking chamber through a viewing opening in the cooking chamber wall. The cooking chamber camera is movable during an operating sequence from a resting position into a capturing position in order to capture the image and back from the capturing position into the resting position after having captured the image, with the cooking chamber camera being subject to more heat from the cooking chamber in the capturing position than in the resting position.

## Claims

### Claim 1

A household cooking appliance, comprising:
a cooking chamber delimited by a cooking chamber wall; and
a cooking chamber camera located outside of the cooking chamber, for capturing an image from the cooking chamber through a viewing opening in the cooking chamber wall, said cooking chamber camera being movable during an operating sequence from a resting position into a capturing position in order to capture the image and back from the capturing position into the resting position after having captured the image, with the cooking chamber camera being subject to more heat from the cooking chamber in the capturing position than in the resting position.

### Claim 2 (depends on 1)

The household cooking appliance of claim 1, wherein in the resting position the cooking chamber camera is moved further away from the cooking chamber than in the capturing position.

### Claim 3 (depends on 1)

The household cooking appliance of claim 1, wherein a region between the viewing opening and the cooking chamber camera is free of a fixed optical element.

### Claim 4 (depends on 1)

The household cooking appliance of claim 1, wherein the cooking chamber camera is movable in a rectilinear manner between the resting position and the capturing position.

### Claim 5 (depends on 1)

The household cooking appliance of claim 1, wherein the cooking chamber camera is movable on a curved track between the resting position and the capturing position.

### Claim 6 (depends on 1)

The household cooking appliance of claim 1, further comprising an optically transparent cover element designed to cover the viewing opening.

### Claim 7 (depends on 1)

The household cooking appliance of claim 1, further comprising a closable screen designed to block an incidence of thermal radiation through the viewing opening onto the cooking chamber camera when the cooking chamber camera is in the resting position, and to open up a field of view of the cooking chamber camera when the cooking chamber camera is in the capturing position.

### Claim 8 (depends on 1)

The household cooking appliance of claim 1, wherein the cooking chamber camera is mounted to enable turning thereof.

### Claim 9 (depends on 1)

The household cooking appliance of claim 1, wherein the operating sequence is a cooking sequence.

### Claim 10

A method for operating a household cooking appliance, said method comprising:
moving during an operating sequence a cooking chamber camera located outside of a cooking chamber of the household appliance from a resting position in which the cooking chamber camera is subject to less thermal stress, into a capturing position in which the cooking chamber camera is located closer to a viewing opening in a cooking chamber wall and subject to greater thermal stress;
triggering the cooking chamber camera in the capturing position to capture an image from the cooking chamber through the viewing opening; and
moving the cooking chamber camera from the capturing position back into the resting position.

### Claim 11 (depends on 10)

The method of claim 10, wherein for each capture of an image from the cooking chamber the cooking chamber camera is moved from the resting position into the capturing position and back from the capturing position into the resting position.

### Claim 12 (depends on 10)

The method of claim 10, further comprising preventing the cooking chamber camera from moving into the capturing position when reaching or exceeding a critical cooking chamber temperature.
