In another embodiment, the crumb tray 120 may rest on the lower wall 76 of the heat shield 68 and may be configured to be heated by the lower heating element 42 and radiate heat towards the plate 48. In a further embodiment, the crumb tray 120 may extend on the lower wall 76 with the channel 122 extending to allow for the lower heating element 42 to be exposed such that the lower heating element 42 may directly heat the cooking chamber 14. In another embodiment, the crumb tray 120 may be formed from steel or aluminum sheet material, or any other metallic sheet structure. Such crumb tray 120 may be readily removable from, and positionable within, the oven 10 upon opening the front door 30, as depicted by arrow 123, such that the front door 30 may be sized to facilitate ready access to the crumb tray 120 below the plate 48.
With reference to FIGS. 6 and 8, as previously set forth, the portable oven 10 may include a control panel 66, which may also be referenced as a controller. The portable oven 10 may be powered with a typical residential outlet, for example, an outlet that may supply 120 or 240 volts, such that the oven 10 may be supplied with such power with a power cord 124. The control panel 66 may include or be associated with input and output devices 130, 132. The input device 130 may include analog type knobs, switches and/or buttons integrated with the oven 10. Further, the input device 130 may be a touch sensitive digital display, or a combination of digital and analog type input controls. Such touch sensitive digital display may also be the output device 132. The output device may also be a secondary display or a non-touch sensitive display. In another embodiment, the control panel 66 may also include one or more processors 134 and one or more memory 136, which may include programming and software designed and configured to implement the functions of the portable oven 10, as known by one of ordinary skill in the art, such as the previously discussed pre-set controls. Further, in another embodiment, the oven 10 may include one or more sensors 138, such as temperature sensors, that may be coupled to the control panel 66 and positioned in or on the oven 10 at locations to assist the user to know the actual temperatures of the external surface of the portable oven and/or the cooking chamber 14 of the portable oven 10. The control panel 66 of the portable oven 10 may be coupled to each of the fan motor 78 of the fan 52, the upper and lower heat elements 40, 42 and the motor 106 to rotate the plate 48 of the portable oven.

In this manner, the portable oven 10 may be employed by a user for indoor and outdoor use and to cook various types of food with multiple cooking modes within the same cooking chamber 14, such as employing the cooking chamber 14 as an oven as well as employing the cooking chamber 14 for air frying therein. As previously set forth, the pre-set controls may be displayed to a user as, for example, (1) fresh pizza, (2) frozen pizza, (3) bake, and/or (4) air fry, each of which may be implemented at the control panel 66 or with a control knob. As such, the portable oven 10 may be employed in various cooking modes relative to, for example, the pre-set controls within a single cooking chamber. For example, upon the portable oven 10 being used in an air frying mode (which may be implemented in the pre-set controls with the control panel 66), the upper heating element 40 and the fan 52 may be automatically electrically activated for cooking food within the cooking chamber. In the air frying mode, the lower heating element may not be activated or may be activated at a low level. Further, upon the portable oven 10 being used in an oven mode or a pizza oven mode (which may apply with slight variations to each of the pre-set controls of fresh pizza, frozen pizza, and bake), the upper and lower heating elements 40, 42 may be activated via the control panel 66 and its programming therein. In some examples, the pre-set controls of the oven mode for cooking “fresh pizza” may include pre-heating the cooking chamber 14 by only heating the lower heating element 42 to heat the plate 48 and, upon completing the step of pre-heating the cooking chamber 14, then activating the upper heating element 40 while maintaining the temperature of the plate 48 or turning the lower heating element off. There may be variations in how the upper and lower heating elements 40, 42 are activated between the variations of oven mode for cooking “fresh pizza, frozen pizza, and bake,” as set forth in the pre-set controls and the programming therewith. In this manner, the portable oven 10 may be employed to cook different types of food with differently types of cooking modes.

The oven control knob 161 may be configured to control the heating of such upper and lower heating elements 240, 242 with pre-programmed or pre-set controls selectable by the user at the oven control knob 161. For example, the oven control knob 161 may include an LCD screen, associated therewith, that may provide temperature detail of the cooking chamber 208. As such, the controller may be interconnected to one or more temperature sensors located at various positions within the cooking chamber 208. Further, the pre-set controls selectable with the oven control knob 161 may include a pre-determined heating procedure for baking a fresh pizza or other bread type food, for example, or another pre-set control for cooking a frozen pizza, and another pre-set control for air-frying within the cooking chamber 208, and another pre-set control for reheating food, cooking fresh pizza or frozen pizza, similar to that described for the portable oven 10 in the previous embodiment. Such pre-set controls may selectively employ the upper and/or lower heating elements 240, 242 for predetermined periods of time and for predetermined temperatures as well as selectively employ the lower fan 252 for moving or mixing air within the cooking chamber 208. Such oven control knob 161 may be interconnected with one or more processors and one or more memory, which may include programming and software designed and configured to implement the functions of the oven portion 152 of the cooking station 150, as known by one of ordinary skill in the art, similar to that described for the portable oven 10 (see FIG. 8), set forth herein. In other words, the description of the electronic controls of the control panel 66 of the portable oven 10 (see FIG. 8) set forth previously are applicable to the functionality of the control knob 161 and the electronics associated with the oven portion 152 of the cooking station 150 of this embodiment.
Now with reference to FIGS. 10 and 14, as previously stated, the griddle device 156 or the second portion 162 of the cooking station 150 will now be further described. The front, rear, left, and right panels 176, 178, 180, 182 of the second portion 162 may extend to define a burn box 183 (see also, FIG. 11). The burn box 183 may extend to define an inner portion 262. The inner portion 262 of the burn box 183 may include multiple elongated burners 264 extending between the front panel 176 and the rear panel 178. The front panel 176 may also include controls, such as burner knobs 266 and an igniter 268. The burner knobs 266 and igniter 268 may be configured to control gas flow through the burners 264 and ignite fuel, such as propane or natural gas. The griddle device 156 may include a griddle 270 configured to be positioned over and supported by the burn box 183 so as to be positioned above the multiple elongated burners 264 and adjacent an upper periphery 272 of the burn box 183. The griddle 270 may extend with a flat cooking surface. In other embodiments, the second cooking portion 158 may include structure for suspending a grate or grill structure. Each of the burner knobs 266 may include the appropriate valves and components associated therewith configured to control gas being supplied to the gas burners or elongated burners 264, as known to one of ordinary skill in the art. Further, although only some of the primary components for operating the elongated burners 264 and the ignitor 268 for operating the upper cooking portion or griddle device 156 are described herein, the remaining components that may be needed for proper functioning of the cooking station 150 may be incorporated herewith, as known by one of ordinary skill in the art. Further, a similar griddle portion or griddle device is described in multiple embodiments of commonly assigned U.S. patent application Ser. No. 17/887,024, filed Aug. 22, 2022, entitled “OUTDOOR COOKING STATION WITH MULTIPLE INDEPENDENT COOKING MODES AND METHOD THEREOF,” the disclosure of which is hereby incorporated by reference herein in its entirety.
With reference to FIGS. 10, 14, and 15, the inner portion 262 of the burn box 183 may include angled panels 274 positioned below the multiple elongated burners 264. The angled panels 274 may be coupled to the front panel 176 and the rear panel 178 and may extend inward and slope downward towards one another at an angle. The angled panels 274 may extend at an angle towards the first portion 160 of the cooking station 150. The burn box 183 may also include the before described lower panel 276 that may also extend to define a lower ventilation portion 277 that may be coupled to the angled panels 274. The lower ventilation portion 277 may extend upwards from the angled panels 274 defining vertical components 278 and horizontal component 280, each of which may be formed from sheet metal. The vertical components 278 and the horizontal component 280 may extend with ventilation openings 282 therein for ventilation since the lower panel 276 may be positioned above the oven portion 152 of the cooking station 150. The horizontal component may include upper and lower horizontal components, the lower horizontal component may not include ventilation openings and the upper horizontal component may include the ventilation openings 282. The lower horizontal component may extend as a panel above the oven portion and act as a heat shield and the ventilation openings in the upper horizontal components as well as the vertical components facilitate minimizing heat from the oven portion 152 positioned below the lower horizontal component. In this manner, the lower panel 276 and the lower ventilation portion 277 may act as a heat shield relative to heat from the oven portion 152 as well as structure for cooling off the lower panel 276.
The lower ventilation portion 277 may be configured to direct heat and warmed air from below the multiple elongated burners 264 out from under the second portion 162. The vertical and horizontal components 278, 280 may include multiple ventilation openings 282 defined therein. On the horizontal component 280, the ventilation openings 282 may be positioned directly below the multiple elongated burners 264 such that the openings 282 may not be within the line of sight or a direct line between the gas flame of the burners 264 and the openings 282. Such openings 282 being mis-aligned with the gas flame of the burners 264 may prevent direct radiation heat from readily moving through the openings 282 to heat structure through the openings 282, thereby, minimizing heating of the structure below the upper horizontal component. Further, the lower ventilation portion 277 may be coupled to the angled panels 274 extending upwards and above the angled panels 274. The angled panels 274 may direct heat and air flow towards the multiple outlets 282 defined on the vertical panels 278 of the lower ventilation portion 276. As such, the lower ventilation portion 277 with its openings 282 defined therein may assist in minimizing the heating of the upper cooking portion or the lower structure of the burn box 183 from heat of the oven portion 152 of the cooking station 150.
