Abstract

A combination oven control interface includes a feature for an operator to select a setpoint temperature (T); and a feature for automatically selecting at least one humidity information ( 101 ) representative of a setpoint humidity level (H %) and of a cooking mode (M), the automatic selection taking into account the selected setpoint temperature (T).

Claims (34)

1. A combination oven control interface, comprising:

means for an operator to select a setpoint temperature;

means for automatically selecting at least one humidity information representative of both a setpoint humidity level and of a cooking mode, said automatic selection taking into account the selected setpoint temperature, wherein the means for automatically selecting is configured such that:

the cooking mode is a steam cooking mode in the case of the selected setpoint temperature being a first temperature;

the cooking mode is a convection cooking mode in the case of the selected setpoint temperature being a second temperature; and

the cooking mode is a combination steam and convection cooking mode in the case of the selected setpoint temperature being a third temperature.

2. The combination oven control interface according to claim 1 , further comprising means of displaying each of the setpoint temperature, the humidity information and the applicable one of the steam cooking mode, the convection cooking mode or the combination steam and convection cooking mode.

3. The combination oven control interface according to claim 2 , further comprising means of displaying a measured value of the temperature in the oven and/or of a calculated value of the setpoint humidity level in the oven.

4. The combination oven control interface according to claim 2 , wherein the means of displaying comprises a display screen.

5. The combination oven control interface according to claim 4 , wherein the means of displaying is configured to display the following information on the display screen in a representative arrangement in the following order: the setpoint temperature, then the humidity information, then the applicable one of the steam cooking mode, the convection cooking mode or the combination steam and convection cooking mode.

6. The combination oven control interface according to claim 1 , wherein the means of displaying is configured to display information indicating that the means for automatically selecting are activated.

7. The combination oven control interface according to claim 1 , wherein:

the convection cooking mode corresponds to a setpoint humidity level defined by a first value range between 0% and A %;

the combination steam and convection cooking mode corresponds to a setpoint humidity level defined by a second value range between A % and B %;

the steam cooking mode corresponds to a setpoint humidity level defined by a third value range that is higher than B %, and

where A<B.

8. The combination oven control interface according to claim 7 , characterized in that A % is between 30% and 60% and B % is between 80% and 99%.

9. The combination oven control interface according to claim 1 , wherein the means for automatically selecting is configured to take into account a pre-established correspondence between setpoint temperature values and setpoint humidity level values and the steam, convection and combination steam and convection cooking modes.

10. The combination oven control interface according to claim 9 , wherein said pre-established correspondence is saved in an electronic memory in the combination oven.

11. The combination oven control interface according to claim 1 , further comprising means for switching the interface to a first forced mode of operation in which the user can choose a forced humidity level value.

12. The combination oven control interface according to claim 11 , wherein, if the forced humidity value corresponds to the steam cooking mode, then the setpoint temperature is forced by the control interface to a saturated steam temperature.

13. The combination oven control interface according to claim 11 , further comprising means for switching the interface to a second forced mode of operation in which the user can choose a forced cooking mode.

14. The combination oven control interface according to claim 13 , wherein, if the forced cooking mode corresponds to the steam cooking mode, then the setpoint temperature is forced by the control interface to a saturated steam temperature.

15. The combination oven control interface according to claim 11 , further comprising reset means for switching from one of said forced operating modes to a normal operating mode in which the means for automatically selecting is activated.

16. A combination oven, comprising a cooking cavity and a control interface according to claim 1 .

17. A method of controlling a combination oven, comprising:

selection, by an operator, of a setpoint temperature;

the combination oven carrying out an automatic selection of at least one humidity information representative of a setpoint humidity level and of a cooking mode, said automatic selection taking into account the selected setpoint temperature such that the cooking mode can be any one of a steam cooking mode, a convection cooking mode, or a combination steam and convection cooking mode, depending upon the selected setpoint temperature.

18. A combination oven control interface, comprising:

means for an operator to select a setpoint temperature;

means for automatically selecting at least one humidity information representative of both a setpoint humidity level and of a cooking mode, said automatic selection taking into account the selected setpoint temperature, wherein the means for automatically selecting is configured such that:

the cooking mode is a steam cooking mode in the case of the selected setpoint temperature being in a first temperature range;

the cooking mode is a convection cooking mode in the case of the selected setpoint temperature being in a second temperature range; and

the cooking mode is a combination steam and convection cooking mode in the case of the selected setpoint temperature being in a third temperature range.
