Abstract

A cooking appliance includes sidewalls and a rear wall defining a heating cavity. At least one heat source is in thermal communication with the heating cavity. An oven cavity connector is disposed within an interior surface of the heating cavity. The oven cavity connector is in communication with the heating cavity. A first tray sliding structure is disposed proximate opposing vertical sidewalls of the heating cavity. A second tray sliding structure is disposed proximate the opposing vertical sidewalls and is vertically offset relative to the first tray sliding structure. A powered accessory tray has a connecting plug, the powered accessory tray being alternatively and selectively engaged with one of the first and second sliding tray structures, and the connecting plug is in selective communication with oven cavity connector when the powered accessory tray is engaged with any one of the first and second tray sliding structures.

First claim

What is claimed is:

1. A powered accessory tray system for use in a cooking appliance, the powered accessory tray system comprising:
a plurality of powered accessory trays, each powered accessory tray comprising:
a base tray that selectively engages a tray sliding structure of a plurality of tray sliding structures defined within a heating cavity of the cooking appliance, the base tray being slidably engaged with the tray sliding structure;
a powered portion supported by the base tray, wherein the powered portion receives electrical power from the cooking appliance; and
a connecting plug in communication with the cooking appliance and the powered portion of the powered accessory tray, the connecting plug having an identifier portion having a predetermined pattern of electrical tabs, that corresponds to a respective powered accessory tray of the plurality of powered accessory trays, wherein selective engagement of the connecting plug with an oven cavity connector disposed within the heating cavity of the cooking appliance places the powered portion in communication with the cooking appliance;

wherein the identifier portion of the connecting plug includes indicative data that corresponds to the respective powered accessory tray of the plurality of powered accessory trays;
wherein the identifier portion is configured to selectively engage an accessory detection mechanism disposed within the oven cavity connector and to place the identifier portion in signal communication with the cooking appliance to transfer the indicative data including predetermined operational parameters to the cooking appliance, when the identifier portion of the connecting plug engages to the accessory detection mechanism.

2. The powered accessory tray system of claim 1 , wherein a control unit of the cooking appliance is in communication with the oven cavity connector and a user interface of the cooking appliance.

3. The powered accessory tray system of claim 2 , wherein when a connected powered accessory tray of the plurality of powered accessory trays is in communication with the oven cavity connector, the indicative data of the identifier portion of the connected powered accessory tray places the connected powered accessory tray in signal communication with the user interface of the cooking appliance.

4. The powered accessory tray system of claim 1 , wherein at least one of the powered accessory trays of the plurality of powered accessory trays includes a motor assembly, wherein the base tray is in selective communication with one of the plurality of tray sliding structures and the motor assembly is in selective communication with the oven cavity connector, and wherein the motor assembly is in rotational communication with a rotisserie insert assembly.

5. The powered accessory tray system of claim 1 , wherein the powered portion of at least one of the powered accessory trays includes an electrical heating element, wherein an accessory insert of the at least one powered accessory tray includes at least one of a grilling insert and a cooking stone insert.

6. The powered accessory tray system of claim 1 , wherein the powered portion of at least one of the powered accessory trays includes an electrical heating element, wherein the electrical heating element is used as part of a dedicated heating chamber that is selectively maintained at a temperature different than the heating cavity of the cooking appliance.

7. The powered accessory tray system of claim 6 , wherein the dedicated heating chamber includes at least one of a steamer insert and a smoker insert, a rotisserie insert, and a grilling insert.

8. A powered accessory tray for use in a cooking appliance, the powered accessory tray comprising:
a base tray that selectively engages a tray sliding structure of a plurality of tray sliding structures defined within a heating cavity of the cooking appliance, the base tray being slidably engaged with the tray sliding structure;
a powered portion supported by the base tray, wherein the powered portion receives electrical power from the cooking appliance, wherein the powered portion includes an electrical heating element and a drive motor; and
a connecting plug in communication with the cooking appliance and the powered portion of the powered accessory tray, wherein selective engagement of an identifier portion of the connecting plug with an oven cavity connector disposed within the heating cavity of the cooking appliance places the powered portion in communication with the cooking appliance, wherein the identifier portion includes a predetermined pattern of electrical tabs;
wherein the identifier portion of the connecting plug includes indicative data including operational parameters of the powered accessory tray; and
wherein the identifier portion is configured to selectively engage an accessory detection mechanism disposed within the oven cavity connector and to place the identifier portion in signal communication with the cooking appliance to transfer the indicative data to the cooking appliance, when the identifier portion of the connecting plug engages to the accessory detection mechanism.

9. The powered accessory tray of claim 8 , wherein the drive motor is a rotisserie motor coupled with a rotisserie tool.

10. The powered accessory tray of claim 8 , wherein the drive motor is attached to a regulating mechanism that controls an amount of steam that is delivered to an accessory heating mechanism of the base tray.
