Abstract

Food preparation apparatus and associated methods. In one method, dough is proofed in an oven compartment and then baked in the same oven compartment. Temperature and/or humidity can be controlled during proofing and/or baking cycles. A blower may be used, for example, to exhaust gas to ambient to reduce heat and/or moisture in the compartment. For example, the blower may be used between proofing and baking cycles to prepare an environment in the oven compartment for the baking cycle.

First claim

What is claimed is:

1. A food preparation apparatus comprising:
a food preparation chamber,
at least one controller,
multiple food preparation environment control devices responsive to the at least one controller to adjust a food preparation environment in the food preparation chamber, and
a user interface permitting a user to program a food preparation recipe to be executed by the food preparation apparatus such that the controller controls the food preparation environment control devices according to the recipe, the user interface including:
a user input for programming the recipe, the user input being configured for receiving at least one parameter for controlling at least one of the food preparation environment control devices, the at least one parameter defining an operational state of the at least one food preparation environment control device, and
a graphical display operatively connected to the user input and configured to, before execution of the programmed recipe, display as a graph representations of operational states of the multiple food preparation environment control devices with respect to time according to the programmed recipe.

2. The food preparation apparatus as set forth in claim 1 , wherein the user input includes at least one actuator for receiving the at least one parameter, and the user interface further comprises a recipe program screen, the at least one actuator and the graphical representation being shown on the recipe program screen at the same time.

3. The food preparation apparatus as set forth in claim 1 , wherein the user interface comprises a touch screen including the user input and the graphical display.

4. The food preparation apparatus as set forth in claim 1 , wherein the user input includes a parameter value display and an associated actuator for adjusting a parameter value displayed on the parameter value display.

5. The food preparation apparatus as set forth in claim 1 , wherein the graphical display updates the graph in real time according to at least one parameter received by the user input.

6. The food preparation apparatus as set forth in claim 1 , wherein the user input is configured for receiving multiple parameters for controlling the at least one food preparation environment control device, the user input including color indicators associated with respective parameters, and the graphical display displaying on the graph representations of operational states associated with the parameters using color corresponding to respective color indicators.

7. The food preparation apparatus as set forth in claim 1 , wherein the operational states are representative of whether the food preparation environment control devices are active or inactive.

8. The food preparation apparatus as set forth in claim 1 , wherein the user input permits the user to input parameters associated with different functions of the food preparation apparatus to be performed during the recipe, and the graphical display displays separately on the graph representations of operational states of food preparation environment control devices of the food preparation apparatus associated with different functions of the food preparation apparatus.

9. The food preparation apparatus as set forth in claim 1 , wherein the user input permits the user to input parameters associated with humidification and venting functions of the food preparation apparatus to be performed during the recipe, and the graphical display displays separately on the graph representations of operational states of the food preparation environment control devices of the food preparation apparatus associated with the humidification and venting functions.

10. The food preparation apparatus as set forth in claim 1 , wherein the graphical display displays on the graph overlapping durations of operational states of the food preparation environment control devices.

11. The food preparation apparatus as set forth in claim 1 , wherein the graph displayed by the graphical display includes a bar graph including representations of operational states of the food preparation environment control devices with respect to time.

12. The food preparation apparatus as set forth in claim 1 , further comprising a recipe run screen, the recipe run screen including a countdown time display and an operational status indicator, the countdown time display counting down recipe time, and the operational status indicator indicating an operational state of at least one food preparation environment control device corresponding to the countdown time displayed by the countdown time display.

13. The food preparation apparatus as set forth in claim 12 , wherein the operational status indicator has different states representing respective active and inactive states of the food preparation environment control device.

14. The food preparation apparatus as set forth in claim 12 , wherein the user input includes a color indicator associated with the at least one parameter, and wherein the operational status indicator of the run screen is illuminated in a color corresponding to the color indicator of the user input for indicating an operational state of the associated food preparation environment control device.

15. The food preparation apparatus as set forth in claim 1 , wherein the representations are arranged in the graph according to respective start times of the operational states of the multiple food preparation environment control devices with respect to time.

16. The food preparation apparatus as set forth in claim 15 , wherein the representations each have a size in the graph according to respective duration times of the operational states of the multiple food preparation environment control devices.

17. The food preparation apparatus as set forth in claim 11 , wherein the bar graph displayed by the graphical display includes a horizontal bar graph including representations of operational states of the food preparation environment control devices with respect to time.

18. The food preparation apparatus as set forth in claim 1 , wherein each representation visually indicates a start time and an end time of the operational state of the corresponding one of the multiple food preparation environment control devices.

19. The food preparation apparatus as set forth in claim 1 , wherein the multiple food preparation environment control devices include a heating system and the representations include a heating representation of the operational state of the heating system, the heating representation visually indicating a start time when the heating system is activated and an end time when the heating system is deactivated.

20. The food preparation apparatus as set forth in claim 19 , wherein the multiple food preparation environment control devices include a humidification system and the representations include a humidification representation of the operational state of the humidification system, the humidification representation visually indicating a start time when the humidification system is activated and an end time when the humidification system is deactivated.

21. The food preparation apparatus as set forth in claim 1 , wherein the representations include a first representation and a second representation, each of the first and second representations visually indicating a start time and an end time of the operational states of corresponding two of the multiple food preparation environment control devices, the graphical display configured to arrange the first and second rep
