The attachment mechanism is configured for attachment to a handle of an oven appliance door. The arm extends from the attachment mechanism to the camera, and attaches to at least one of the camera or a housing, if provided. The camera records or transmits images of the oven cavity to, e.g., a user device allowing a user to monitor a doneness of any food items positioned within the oven appliance.

## Background
FIELD OF THE INVENTION
The subject matter of the present disclosure relates generally to a camera for an oven appliance.
BACKGROUND OF THE INVENTION
Oven appliances generally include an insulated and heated oven cavity for baking food items therein. An opening to the oven cavity is covered by an insulated door movable between an open position and a closed position. Commonly, the door includes a transparent panel allowing a user to view the contents of the oven cavity, such as various food items, with the door in the closed position.
Cooking operations of certain food items requires a user to visibly inspect such food items to periodically determine a doneness of such food items. Accordingly, with conventional oven appliances, a user must physically look through the transparent panel of the door to periodically inspect such food items. More recently, however, certain oven appliances have included a camera within the oven cavity, wired to a peripheral screen positioned, e.g., on a control panel of the oven appliance. The camera can allow a user to inspect the doneness of food items within the oven cavity without looking through the transparent panel of the door. However, providing a camera capable of withstanding the relatively high temperatures within the oven cavity can be costly and relatively complex. Additionally, retrofitting a conventional oven appliance with such a camera may also be costly and relatively complex.
Accordingly, a camera assembly for an oven appliance that allows a user to view one or more food items within the oven cavity would be useful. More particularly, a camera assembly for an oven appliance that allows a user to view one or more food items within the oven cavity without requiring installation of a camera within the oven cavity would be particularly beneficial.

Moreover, the lip 72 of the housing 58 has a greater diameter than the attachment portion 70 of the housing 58. When the camera assembly 52 is connected to the oven appliance 10, or more particularly when the attachment mechanism 54 is attached to the handle 40 of the door 36 of the oven appliance 10, the lip 72 may contact the outer surface 74 of the one or more transparent panels 42 of the door 36 and block an amount of ambient light from reaching the camera 60. Notably, such a configuration may be especially effective when, for example, the one or more transparent panels 42 includes a double-pane glass, wherein ambient light may otherwise be reflected off an outside surface of the outer pane and an outer surface of an inner pane.
Reference will now be made to FIGS. 4 and 5. FIG. 4 provides a side cross-sectional view of the housing 58 and camera 60 of the exemplary camera assembly 52 in a first position, and FIG. 5 provides a side, cross-sectional view of the housing 58 and camera 60 of the exemplary camera assembly 52 in a second position
As previously stated, the housing 58 of the camera assembly 52 generally includes the attachment portion 70 and the lip 72. The lip 72 includes a plurality of hooks 76 that are received within a plurality of openings 78 defined in the attachment portion 70 of the housing 58. For the embodiment depicted, the attachment portion 70 includes a ball 80 and a socket 82, with the camera 60 attached to, and positioned at least partially within, the ball 80. The ball 80 is at least partially positioned within the socket 82 and is movable relative to the socket 82, such that an angle of the camera 60 may be adjusted by moving the ball 80 relative to the socket 82. The socket 82 is formed, for the embodiment depicted, of an inner casing 84 and an outer casing 86, joined in any suitable manner around the ball 80. For example, the inner and outer casings 84, 86 may be joined by ultrasonic welding or by using one or more bolts, screws, or other mechanical fasteners. It should be appreciated, however, that in other exemplary embodiments, the socket 82 may be formed in any other suitable manner.
Notably, the exemplary attachment portion 70 depicted is configured with a plurality of preset adjustment settings to allow for easy adjustment of the ball 80 and camera 60. More particularly, the exemplary ball 80 depicted includes three upper indents 88 and three lower indents 90. The socket 82 includes an upper projection 92 and a lower projection 94, the upper projection 92 of the socket 82 configured to fit within one of the three upper indents 88 of the ball 80, and the lower projection 94 of the socket 82 is configured to fit within one of the three lower indents 90 of the ball 80. Each of the upper indents 88 of the ball 80 and lower indents 92 of the ball 80 corresponds to different positions of the ball 80 and camera 60 relative to the socket 82.
Referring still to FIGS. 4 and 5, for the embodiment depicted, the socket 82 of the attachment portion 70 of the housing 58 defines a central axis AC. Additionally, the ball 80 of the attachment portion 70 of the housing 58 and the camera 60 define a viewing axis AV. Despite a relative position of the viewing axis AV to the central axis AC, the central axis AC remains substantially perpendicular to a plane defined by the outer surface 74 of the one or more transparent panels 42 of the door 36. For the embodiment depicted, the viewing axis AV defines an angle 96 with the central axis AC between about zero degrees (see FIG. 4) and up to about plus or minus ten degrees (see FIG. 5, depicting the angle 96 at minus about ten degrees). Accordingly, for the exemplary embodiment depicted, the camera 60 defines a range of motion of approximately twenty degrees relative to the socket 82 of the attachment portion 70 of the housing 58.
It should be appreciated, however, that in other exemplary embodiments, the viewing axis AV may instead define any other suitable angle 96 with the central axis AC. For example, in other exemplary embodiments, the viewing axis AV may define an angle 96 with the central axis AC between about zero degrees and plus or minus about fifteen degrees, plus or minus about twenty degrees, or plus or minus about thirty degrees. Accordingly, in other exemplary embodiments, the camera 60 may instead define a range of motion of approximately thirty degrees, approximately forty degrees, or approximately sixty degrees, respectively. It should also be appreciated, that as used herein, terms of approximation, such as “about” and “approximately,” refer to being within a ten percent margin of error.
Moreover, it should be appreciated that in still other exemplary embodiments, the camera assembly 52 may not include a housing 58, or alternatively, may include any other suitable housing 58. For example, in other exemplary embodiments, the attachment portion 70 of the housing 58 may be fixed such that the camera 60 does not define a range of motion, and additionally, or alternatively, the housing 58 may only include a lip 72 attached directly to the camera 60.
As previously stated, and as is depicted in FIGS. 4 and 5, the camera 60 is attached to the ball 80 of the attachment portion 70 of the housing 58.
