It is generally contemplated that the cooking appliance 10 may be a conventional oven, such as a convection oven, or may be one of a variety of appliances, including a microwave oven. The top wall 22 is spaced from the bottom wall 26 by first and second side walls 30, 32. A door assembly 34 pivotally connects with the cabinet 12 for selectively covering the opening 16. According to aspects of the disclosure, the door assembly 34 may rotate about a pivot axis A disposed adjacent the bottom wall 26 and orthogonal to the first side wall 30 and the second side wall 32. It is generally contemplated that the walls 22, 26, 30, 32 may include a coating (e.g., an acrylic enamel coating or a ceramic coating) to provide ease of cleaning and/or a desired aesthetic appearance to the cooking cavity 14. Additionally, or alternatively, the coating may be a substantially non-stick coating (e.g., polytetrafluoroethylene (PTFE) or ceramic).

As illustrated in FIGS. 1-3, the door assembly 34 includes a door frame 36 and a viewing panel 38. The viewing panel 38 is coupled to, and held in place by, the door frame 36. The viewing panel 38 may be at least partially optically transmissive to allow a user of the cooking appliance 10 to view into the cooking cavity 14 before, during, or after operation of the cooking appliance 10. The viewing panel 38 may be made of glass, a polymer, or some other durable and/or transparent material. The cooking appliance 10 may include a connection assembly 40 for connecting the door assembly 34 with the cabinet 12 and aligning the door assembly 34 during a movement between an open position and a closed position.

A ladder rack assembly 42 includes one or more horizontal racks 44 and one or more vertical rails 46a, 46b coupled to at least one of the first side wall 30 and the second side wall 32. One or more lateral rails 48 may be configured to attach to at least a portion of the vertical rails 46a, 46b and support the one or more horizontal racks 44 in the central portion of the cooking cavity 14. The ladder rack assembly 42 may be configured to receive a cooking tray on which items of food may be supported. Further, a plurality of cooking trays may be supported by the ladder rack assembly 42. The one or more vertical rails 46a, 46b includes a forward vertical rail 46a disposed proximate to the opening 16 of the cooking cavity 14 and a rearward vertical rail 46b is disposed proximate the back wall 18 of the cooking cavity 14. The one or more horizontal racks 44 are coupled to the vertical rails 46a, 46b via the one or more lateral rails 48. The ladder rack assembly 42 is configured to couple to the first side wall 30. Corresponding vertical rails 46a, 46b are coupled to the second side wall 32 such that the cooking tray is supported on each side. The second side wall 32 and the corresponding ladder rack assembly 42 may include similar or identical characteristics as those described herein with respect to the first side wall 30 and the ladder rack assembly 42. The corresponding ladder rack assembly 42 may be substantially symmetrical to the ladder rack assembly 42 such that the corresponding ladder rack assembly 42 is a mirror image of the ladder rack assembly 42. It is contemplated that the corresponding ladder rack assembly 42 may be substantially similar in all or some other aspects.

The cooking cavity 14 may include a fillet 50 that couples the first side wall 30 with the top wall 22, the second side wall 32 with the top wall 22, the first side wall 30 with the bottom wall 26, and the second side wall 32 with the bottom wall 26. Each fillet 50 may help to prevent arcing and/or reduce stress concentrations within the cooking cavity 14. The cooking cavity 14 may further include a rounded periphery 52 along a front portion 54 of the cooking cavity 14. The rounded periphery 52 may help to provide a better seal between the front surface of the rounded periphery 52 when the door assembly 34 is in a closed position.

Referring again to FIGS. 1-3, a convection fan 56 may be concealed behind a baffle cover 58 extending from the back wall 18 into the cooking cavity 14. During operation of the convection fan 56, movement of cavity air within the cooking cavity 14 generates a high pressure space 60 between the baffle cover 58 and the back surface of the cooking cavity 14. To assist in forming this high pressure space 60, the baffle cover 58 defines a plurality of vent apertures 62 that cooperate with the convection fan 56 to generate the high pressure space 60 that directs the cavity air from the cooking cavity 14.

As exemplarily illustrated in FIGS. 1-3, a lighting assembly 28 is coupled to the back wall 18 adjacent the upper portion 20 and is configured to project light into the cooking cavity 14. Although the lighting assembly 28 is shown disposed adjacent the upper portion 20, it should be appreciated that the lighting assembly 28 can, additionally or alternatively, be coupled to the upper portion 20. The lighting assembly 28 may be disposed above the ladder rack assembly 42 and have a substantially elongated shape, as illustrated. The lighting assembly 28 may extend between a first end 66, disposed adjacent the first side wall 30, and a second end 68, disposed adjacent the second side wall 32. According to various aspects of the disclosure, the lighting assembly 28 may be disposed horizontally and have a length L substantially equal to a width of the baffle cover 58. Although the lighting assembly 28 is illustrated spaced from the top wall 22, it should be appreciated that the lighting assembly 28 may coincide with a first intersection 70 between the top wall 22 and the back wall 18 and/or a second intersection 72 between the bottom wall 26 and the back wall 18. Further, the first end 66 of the lighting assembly 28 may be disposed in or near a first corner 74 formed by the top wall 22, the back wall 18, and the first side wall 30, and the second end 68 of the lighting assembly 28 may be disposed in or near a second corner 76 formed by the top wall 22, the back wall 18, and the second side wall 32. Additionally or alternatively, the lighting assembly 28 may be disposed in or near a third corner 78 formed by the bottom wall 26, the back wall 18, and the first side wall 30, and the second end 68 of the lighting assembly 28 may be disposed in or near a fourth corner 80 formed by the bottom wall 26, the back wall 18, and the second side wall 32. Additionally, or alternatively, the lighting assembly 28 may mount to the fillet 50 at an acute angle relative to the back wall 18, the top wall 22, the bottom wall 26, and/or the first and second side walls 30, 32.

The lighting assembly 28 may include a cover 82 made from a suitable heat resistant material (e.g., borosilicate glass, an opalescent material, etc.). The cover 82 may be optically translucent according to various aspects of the present disclosure. It should be appreciated that the cover 82 may be heat-treated to withstand high temperatures of the cooking cavity 14. The cover 82 may serve as a light guide to diffuse or otherwise affect light provided by the lighting assembly 28. Stated differently, the cover 82 may serve as a lens for the lighting assembly 28. The cover 82 may be removable for ease of cleaning the cover 82.

The cover 82 may include a light projection surface S configured to collimate light toward the central portion of the cooking cavity 14. The light projection surface S includes a planar extent 82a that extends at an acute angle relative to the back wall 18. The planar extent 82a may extend at least partially along the length L of the lighting assembly 28. Top and bottom side extents 82b, 82c may extend from the planar extent 82a toward the back wall 18 to connect the cover 82 with the back wall 18. The top and bottom side extents 82b, 82c may also be configured to direct light toward the central portion. Additionally or alternatively, the cover 82 may be curved between the top and bottom side extents 82b, 82c. A first end extent and a second end extent may extend between the top extent 82b and the bottom extent 82c and correspond with the first end 66 and the second end 68 of the lighting assembly 28, respectively. The lighting assembly 28 may include one or more light sources 84, such as light-emitting diodes (LEDs). The one or more LEDs may include an LED strip disposed within the elongated lighting assembly 28. A controller 85 may be configured to operate the LEDs to have one or more predetermined behaviors (e.g., blinking, changing colors, and changing brightness). The controller 85 may be in communication with, or may be the same as, the cooking appliance controller, and may be operable via an human-machine interface (HMI) 86 external to the cooking cavity 14. According to some aspects of the disclosure, the light source 84 may be in a traditional tube form (similar to fluorescent bulbs), such as an LED tube, having sockets disposed at the first end 66 and the second end 68 of the lighting assembly 28. The light source 84 may extend from adjacent the first side wall 30 to adjacent the second side wall 32. Additionally, or alternatively, the lighting assembly 28 may incorporate a light source 84 including strip-type LED strands.

According to an exemplary aspect of the disclosure shown in FIG. 2, the lighting assembly 28 may include a first light source 84a and a second light source 84b. The first light 84a source can be disposed adjacent an intersection of the back wall 18, the top wall 22, and the first side wall 30 of the cabinet (i.e., the first corner 74), and the second light source 84b can be disposed adjacent an intersection of the back wall 18, the top wall 22, and the second side wall 32 of the cabinet 12 (i.e., the second corner 76). According to some aspects of the present disclosure, a plurality of light sources 84 may be distributed along a width of the back wall 18 between the first side wall 30 and the second side wall 32. For example, the length L of the lighting assembly 28 may extend in a width-wise direction along the back wall 18. The back wall 18 may generally be planar in shape.

Referring now to FIGS. 4-7, the lighting assembly 28 is configured to project light, illustrated by arrow 88, at a projection angle Θ that is an acute angle relative to the back wall 18. The light may be directed toward the central portion of the cooking cavity 14. As previously discussed, the central portion may correspond to a location of the horizontal racks 44. For example, the lighting assembly 28 may be configured to project the light from the upper portion 20 of the back wall 18 toward the bottom wall 26 at an acute angle relative to the back wall 18 and onto the horizontal racks 44. The light may have a high-intensity range of light 90 and a low-intensity range of light 92, with the high-intensity range of light 90 focused on the central portion and the low-intensity range 92 dispersed throughout the cooking cavity 14. The lighting assembly 28 can thereby be configured to minimize glare and/or dazing light distributed at the opening 16.

A support surface 94 can be disposed on the back wall 18 and extend at an acute angle relative to the back wall 18 of the cabinet 12. The support surface 94 may be recessed or protruding from a back surface of the back wall 18. The back surface may be the generally planar surface that is generally the rear-most portion of the cabinet 12. The lighting assembly 28 may be coupled to the support surface 94 and configured to project light normal to the support surface 94. As exemplarily illustrated in FIG. 4, the support surface 94 may be formed on a protrusion 96 extending from the back wall 18 into the cooking cavity 14. According to aspects of the disclosure, the cover 82 of the lighting assembly 28 may be flush with the support surface 94 and the light source 84 (and/or the first and second light sources 84a, 84b) may be disposed in a recess 98, or indentation, defined by and/or extending into the back wall 18 adjacent the support surface 94, as generally shown in FIG. 6. As illustrated in FIG. 5, the cover 82 of the lighting assembly 28 may also be housed within the recess 98. It should be appreciated that the acute angle at which the support surface 94 extends may complementarily relate to the projection angle Θ. For example, if the support surface 94 extends at an angle of 30 degrees relative to the back wall 18, then the projection angle Θ may be configured to project at an angle of 60 degrees relative to the back wall 18. More particularly, continuing with the non-limiting example, the high-intensity range of light 90 may have a center ray of light 100 projecting at an angle of 60 degrees relative to the back wall 18.

Referring more specifically to FIG. 7, the cover 82 may extend at an acute angle relative to the back wall 18 to direct the light from the light source 84 toward the central portion of the cooking cavity 14. More specifically, the light projection surface S may extend at an acute angle relative to the back wall 18. According to some aspects of the present disclosure, the center ray of light 100 may be configured to project generally perpendicular to the back wall 18 over a distance D₁ from the light source 84 to the cover 82. Further, the light source 84 (and/or the first and second light sources 84a, 84b) may be spaced from the cover and operable to direct the central ray of light 100 at an acute angle relative to the planar extent 82a. It is generally contemplated that one or both of the top and bottom side extents 82b, 82c may extend generally perpendicular to the back wall 18 and be at least partially disposed within the recess 98. The cover 82 may be operable to collimate the light about a focus angle β relative to the back wall 18. In this way, the projection angle Θ formed between the support surface 94 and the center ray of light 100 may be in the range of between 0 degrees (i.e. parallel) and 90 degrees relative to the back wall 18 while still providing focused light into/onto the central portion of the cooking cavity 14. Further, according to some aspects of the disclosure, the support surface 94 may be generally parallel to the back wall 18, or, alternatively, the acute angle formed by support surface 94 may be a different angle than the acute angle the cover 82 forms with the back wall 18. It is generally contemplated that the distance D₁ may influence the breadth of the high-intensity range of light 90 (e.g., a greater distance D₁ may reduce the breadth of the high-intensity range of light 90). The distance D₁may be optimized to provide the desired breadth of the high-intensity range of light 90, such as in the range of between 45 and 90 degrees.

It will be contemplated from the present disclosure that, additionally or alternatively, the lighting assembly 28 can be configured to project light toward one or both of the side walls 30, 32 or the top wall 22. Stated differently, the lighting assembly 28 may be disposed on the lower portion 24 and be configured to project light at an acute angle upwardly toward the top wall 22, or the lighting assembly 28 may be generally vertically disposed adjacent one or both of the side walls 30, 32 and be configured to project light toward the opposing side wall. In these configurations, the high-intensity range of light 90 may be restrained from being directed toward the opening to reduce glare according to an observer outside of the cooking cavity 14 looking into the cooking cavity 14.
