Automated cleaning of cooking apparatus
View Patent ↗A cooking apparatus includes a base including a lower heating plate an upper heating unit including an upper heating plate and a cleaning structure configured to move a cleaning blade along at least one of the lower heating plate and the upper heating plate. The apparatus also includes a control circuit configured to control movement of the cleaning blade across the one of the lower heating plate and the upper heating plate.
1. A cooking apparatus, comprising:
a base including a lower heating plate;
an upper heating unit including an upper heating plate;
a cleaning structure including a track defining a path and a cleaning blade movable about the path defined by the track to clean only one of the lower heating plate and the upper heating plate at a time, wherein the track of the cleaning structure is mounted to one of the upper heating unit and a structure separate from the upper heating unit and the base; and
a control circuit configured to control movement of the cleaning blade across the one of the lower heating plate and the upper heating plate.
2. The cooking apparatus of claim 1 , wherein the track extends a length of the at least one of the lower heating plate and the upper heating plate.
3. The cooking apparatus of claim 1 , wherein the cleaning blade includes a first edge and a second edge opposite the first edge, the first edge and the second edge configured to simultaneously clean the lower heating plate and the upper heating plate, respectively while the upper heating plate is positioned substantially parallel to the lower heating plate.
4. The cooking apparatus of claim 1 , wherein the cleaning structure includes a scraping blade to scrape food product remnants from the one of the lower heating plate and the upper heating plate.
5. The cooking apparatus of claim 4 , wherein the cleaning blade is a squeegee and the scraping blade is connected to the squeegee to move co-linearly with the squeegee across the one of the lower heating plate and the upper heating plate.
6. The cooking apparatus of claim 1 , wherein the cleaning structure includes a food product lifting blade connected to the cleaning blade to remove a food product from the lower heating plate as the cleaning blade moves across the lower heating plate.
7. The cooking apparatus of claim 1 , wherein the cleaning blade is configured to move along a path defined by at least the track belt.
8. The cooking apparatus of claim 1 , wherein the control circuit is configured to initiate a cleaning operation of the cleaning structure based on a user input.
9. The cooking apparatus of claim 1 , wherein the control circuit is configured to initiate a cleaning operation of the cleaning structure based on detecting that a cooking operation is completed.
10. The cooking apparatus of claim 1 , wherein:
the control circuit is configured to move the cleaning blade as part of a cleaning operation in response to receive a command.
11. The cooking apparatus of claim 10 , wherein the command to perform a cleaning operation is generated by a user input on the cooking apparatus.
12. The cooking apparatus of claim 10 , wherein the command to perform a cleaning operation is generated by a control program of the control circuit based on detecting a termination of a cooking operation.
13. The cooking apparatus of claim 12 , wherein the command to perform the cleaning operation is generated a predetermined period of time after termination of the cooking operation.
14. The cooking apparatus of claim 12 , wherein the command to perform the cleaning operation is generated based on detecting that the one of the lower heating plate and the upper heating plate is at a predetermined temperature.
15. The cooking apparatus of claim 10 , wherein the cleaning operation includes moving the upper heating plate to be substantially parallel to the lower heating plate while the cleaning blade moves across the at least one of the lower heating plate and the upper heating plate.
16. The cooking apparatus of claim 15 , wherein the cleaning blade includes a first edge and a second edge opposite the first edge, the first edge configured to clean the upper heating plate while the second edge cleans the lower heating plate.
17. The cooking apparatus of claim 10 , wherein the cleaning structure includes a cleaning arm extending between the track, belt or chain and the cleaning blade, and
the cleaning operation includes moving the cleaning blade across the at least one of the upper and lower heating plates includes moving the cleaning arm along the track, belt or chain.
18. The cooking apparatus of claim 10 , wherein:
the control unit is configured to:
determine that the upper heating plate is lifted to a non-cooking position away from the lower heating plate; and
control the cleaning structure to move the cleaning blade across the at least one of the upper and lower heating plates based on the determining that the upper heating plate is lifted to a non-cooking position away from the lower heating plate.
19. The cooking apparatus of claim 10 , wherein the cleaning structure includes a food product lifting blade and the cleaning blade connected to each other,
the cleaning structure moves the cleaning blade across at least the lower heating plate, and
the cleaning structure moves each of the food product lifting blade and the cleaning blade together across the lower heating plate, such that the food product lifting blade lifts a food product off of the lower heating plate prior to the cleaning blade cleaning the lower heating plate.
