• This makes it possible for the user of such a method to achieve an optimization in the level control mode, namely by a reduction of energy consumption and incorrect operation.
• a warning message may also be associated with the activation or deactivation of certain program options.
• the changes in the cooking chamber climate which arise because the cooking chamber door is open over a certain period, are recognized and taken into account in the control of programs running in the level control mode.
• a warning in the context of the present invention such displays are understood that prompt to load or unload the cooking chamber with food.
• the warning messages can affect the individual treatment levels the cooking chamber or the entire cooking space as such.
• a warning in the context of the invention is also an indication of energy saving, for example, refers to the fact that the cooking chamber door of the cooking appliance is now urgently closed, or an indication that to avoid the deterioration of a cooking result of the oven before the next loading at least one treatment level must first be preheated again.
• the alerts can basically be divided into two categories. On the one hand, there are warnings that indicate, for example, the dangers that result when cooking space is too long in the cooking chamber or the temperature in the cooking space is too low for further loading of the cooking space with food. On the other hand, hints or requests can be made, such as suggestions for operating the cooking appliance in order to save energy, displaying which items to be removed from which treatment levels, or the like.
• the cooking chamber of the cooking appliance is first preheated with the cooking chamber door closed. This is to ensure that at the time of loading the cooking chamber with a first food to be cooked suitable for this food cooking chamber conditions prevail.
• the preheating of the cooking chamber is completed, is via an optical and / or acoustic signal of a first warning message in the form of a general Hint or better issued a request that the oven can now be loaded with the first food.
• the user of the cooking appliance will open the cooking chamber door in order to place the first food to be cooked in a first treatment level of the cooking chamber.
• the cooking appliance issues a second warning message, which informs the user of the cooking appliance that the cooking chamber should be loaded faster or the door of the cooking chamber should be closed again.
• the warning message is displayed as sound, linguistically and / or graphically on a display device of the cooking appliance.
• the aim is to ensure on the one hand the quality of the cooking result by the fact that the appropriate climatic conditions after loading the cooking chamber with the first food are actually available.
• the energy required to operate the cooking appliance should be minimized. The latter is achieved in that unnecessary energy losses caused by a cooling of the cooking chamber with the oven door open, can be avoided.
• a third warning message will be issued after 60 seconds.
• This warning message occurs, for example, by a changed, different Wamton and a linguistic and / or textual output: "Loading no longer possible, re-preheat".
• it can also be provided to follow the course of the cooking chamber temperature by means of a cooking chamber temperature sensor provided in the cooking appliance and to output said warning message when the cooking chamber temperature falls below a minimum value.
• the third warning message has become necessary at this time, because the oven temperature has dropped too much to allow a satisfactory cooking result yet.
• the level control program is reset to the "preheat" step.
• the user When closing the oven door then the user then no longer has the ability to set a timer for the first treatment level or to select the first treatment level. Rather, he is made aware by the third warning message that the level control program preheats the cooking chamber again. Thus, even if he has erroneously loaded the cooking space with food, he is still able to recognize his mistake at this time and remove the food from the oven.
• the time until the triggering of the third warning message can be varied depending on the detected door opening angle.
• the larger the door opening angle the shorter the time until the warning message is issued.
• the door opening angle may be used as a parameter, e.g. as a factor that scales the time until the third warning message is output.
• a timer setting is performed, which refers to the treatment level concerned. If the oven door remains open for more than 30 seconds, a fifth warning message appears, as the timer is still active at the same time to indicate that the cooking process in the cooking chamber is interrupted. The warning may become stronger, e.g. in that an audible warning sound becomes louder or a visual indicator flashes faster to alert the user to the increasing urgency of the problem. The fifth warning message thus takes place, as there is still food in the cooking chamber, whose cooking time could no longer be sufficient for naturalgaren. But there is no need to cancel the cooking program, as the door opening times can be processed intelligently. For example, the door opening time can be added to the total cooking time, or the cooking space temperature can be increased in proportion to the door opening time.
• a seventh warning message can be issued in the form of a note if the corresponding items were affected by the fifth warning, after which the items to be checked should be checked Garraumt when loading the other food may have been open too long.
• a changed warning may be provided for a ninth warning message.
• an option to set a timer analogous to the process can be disabled immediately after preheating the level control program as described above. If it is desired to cool the cooking chamber, it is also possible to display as the tenth warning which cooking items can be cooked in the current climate, which can be calculated from the door opening time and possibly the door opening angle. If, for example, the cooking space is still very hot, it may be indicated that steaks can be grilled in the cooking space. If the cooking compartment then gradually cools down, the display changes to "Vegetable steaming possible".
• the door is opened or closed without a timer being selected. If the oven temperature drops after the Garraumt was closed, noticeably from, so it can be assumed that only by mistake no timer was set, although a product was introduced into the oven. An additional indication of such a constellation is when the oven door has been opened and closed, without a timer has expired, and the oven door has been opened for more than 5 seconds. If the door opening angle is also calculated, an additional door opening angle of at least 90 ° over a period of at least 5 seconds can be evaluated as an additional criterion. As the eleventh warning message, in this case, for example, the output "Check Timer" can be made on the display device.
• a twelfth warning message can be generated according to which no further loadings are possible until the cooking space temperature reaches a value sufficient for cooking food has reached.
• Activating or setting a timer can be used to modify the time until a warning message is issued. For example, it may be provided that when setting a timer, the time for issuing the warning message is reset to zero.
