Advantageously, the user controls other cooking parameters by dialog with said control member.

Description

A METHOD OF CONTROLLING THE OPERATION OF AN ELECTRIC OVEN HAVING A PLURALITY OF COOKING MODES, AND APPARATUS FOR IMPLEMENTING THE METHOD The invention relates to a method of controlling the operation of an electric oven having a plurality of cooking modes, and to apparatuses enabling such a method to be implemented.
Electric ovens for consumers can operate in various cooking modes: natural convection, fan heat, grill, and may also include a mode of operation suitable for defrosting food and/or an option for pyrolytic cleaning.
A rotary spit or "rotisserie" function may also be associated therewith.
Operating mode is selected by the user by positioning a knob in an appropriate position, and by positioning other knobs for setting temperature and cooking duration. These various knobs are distributed longitudinally along a strip usually situated above the oven door.
The selected mode of cooking: natural convection, fan heat, bottom heat, or top heat, optionally associated with a fan, then known as "bottom fan heat" and as "fan grill", is normally determined by the type of food to be cooked, and by what needs to be done in addition to cooking: drying (e.g. for tart pastry) or sealing (for meat), etc. A non-professional user generally does not know how to choose the most appropriate mode of cooking, and recipes consulted by the user give only the cooking temperature. This means the user must consult an operating manual, likely to become lost, and then set the operation of the oven by using a plurality of knobs.
The invention mitigates those drawbacks by providing a method of controlling the operation of such an electric oven in which temperature selection determines cooking mode via a control member associated with the oven.
Advantageously, the user controls the other cooking parameters by dialog with the control member.
It has been observed that appropriate cooking is obtained by using a mode of cooking determined by temperature in accordance with the following table:
Temperature T Mode of cooking Oven 40 C # T < 140 C Fan heat 140 C < T < 180"C Bottom fan heat 1800C # T < 230 C Fan heat 230"C s T < 275"C Natural convection Grill/spit 180 C # T < 230 C Grill/spit 230"C s T < 2750C Fan grill/fan spit The oven is fitted with a control member which, when the user selects a temperature, automatically controls operation of the combination of oven elements that enables the appropriate mode of cooking to be obtained, which elements are constituted by bottom and top resistance elements, the fan, and the spit-turning mechanism.
The combinations are as follows: natural convection: bottom and top elements fan heat: bottom and top elements and fan bottom fan heat: bottom element and fan top grill: top elements fan grill: top elements and fan spit: top elements and spit-turning mechanism fan spit: top elements, spit-turning mechanism, and fan The control member is advantageously also designed to control other cooking parameters in accordance with information given by the user, the other cooking parameters normally being duration, starting immediately or later, sequencing two operations such as defrosting followed by cooking, etc. ...
The control member is functionally connected to the operating elements of the above-described oven and also to a dialog interface constituted by a display screen and control buttons. The control member guides the user while setting the oven by displaying messages or questions and by proposing various solutions associated with symbols representing the buttons to be used to obtain those solutions, thereby making the oven easier to use.
Figure 1 shows the dialog interface between the control member and the user; and Figures 2 to 4 show example dialogs.
The dialog interface comprises a screen 1 and an appropriate number of control buttons (restricted to five in the example of Figure 1, i.e. buttons 2, 3, 4, 5, and 6). Naturally, the shape and layout of the buttons can be altered. The layout selected herein is that of four buttons each occupying a sector of a circle and surrounding a central round button. The outer four buttons carry symbols, e.g. - and + for operations that seek to decrease or increase a length of time or a temperature, M for operations that can be performed manually at any time (switching off the oven), and P for selecting a cooking program in memory.
Screen 1 comprises a plurality of zones and an example layout is given in Figure 1. It should be observed that the zones shown in Figure 1 are not all displayed simultaneously on the screen while the oven is in use, with only those zones that are necessary for adjustment or information purposes appearing.
A "time" zone 10 includes a clock 11, the mentions "Duration D" 12 and "End E" 13, and optional flashing as represented by zigzag line 14.
A "message" zone 15 serves to display a question or information relating to oven setting or operation.
A "temperature" zone 16 serves to show the temperature 17, a thermometer symbol 18, and a "key" zone 19 indicating that the oven is locked (during pyrolytic cleaning), and also zig zag lines 20 and 21 representing flashing.
A "buttons" zone 22 displays a selection of parameters or a selection of actions to be performed on a parameter simultaneously with an associated symbol representing the button to be used for selecting the parameter or for acting thereon.
The various zones are displayed by being illuminated, optionally in a plurality of colors. It is possible to use red for setting and green for information.
There follow several examples, that are not limiting in any way, of the way in which the dialog interface can operate.
1) At rest, the clock 11 displays the current time, the message zone 15 is neutral, displaying the trademark under which the oven was sold or displaying a prompt message. In the zone 22, the symbol representing the central button 2 is illuminated.
2) The user has pressed the central button 2. The display shown in Figure 2 then appears: the clock 11 tells the time, the message zone 15 displays the message "Make your selection" while the five symbols representing buttons in the zone 22 are illuminated offering five options: "Program", "Pyrolysis", "Auto oven" (for automatic oven), "Grill", and "Manual" (for manual oven), enabling the user to start setting the oven.
3) If the user opts for automatic operation of the oven, then it is necessary to press on the central button 2. This leads to the display shown in Figure 3: the clock 11 tells the time and the message zone 15 displays the question "Temperature?", the temperature zone 17 displays the temperature in memory, causing it to flash, and the symbols for the buttons 3 and 5 light up. The user then sets the desired temperature using the up button 3 (+) or the down button 5 (-), and then confirms the selection with the central button 2.
4) Assuming that the chosen temperature is 190"C, the situation shown in Figure 4 then appears: the clock 11 tells the time, the message zone 15 specifies "Fan heat" since the temperature 1900C lies in the range corresponding to that particular mode of cooking; the temperature zone 17 is no longer flashing, while the thermometer symbol 18 flashes as the temperature rises.
The symbols for the buttons 3 and 5 remain lighted since the user can still change the temperature, as does the symbol for the button 6 since it is possible to stop the oven.
The symbol for the button 4 lights up proposing the Duration/End option to invite the user to program a duration or a time at which cooking is to end.
If the user presses button 4, the message zone invites the user to select a duration or an end time, and so on until the selection has been programmed using the zones 11, 12, and 13, and the buttons corresponding to the symbols which light up in the zone 22.
Similar operations are performed for other possible selections, with the dialog interface guiding the user through the selection of setting buttons.
Once setting has been completed, the screen displays information concerning the time, the temperature, and the state of progress in cooking ("Cooking now", "Will cook later", "Cooking over").
The programs in memory can be input by the manufacturer or by the user to match the user's habits.
The method of the invention thus relieves the user of making a decision about cooking mode, by automatically selecting the mode which is most appropriate for the selected temperature, and use of the dialog interface makes it possible to combine various knobs in a single control having buttons that are easier to operate.
To implement this method, an electric oven is provided fitted with a control member that is functionally connected to the elements of the oven and also to a dialog interface constituted by a display screen and control buttons, the screen displaying messages or questions together with possible answers in association with symbols of the control buttons that correspond to said answers.
