The The present invention relates to a method of programming a cooking appliance in which user-specific programs or program steps entered by a user stored and can be performed, as well as a cooking appliance to carry out such a method.

Program-controlled cooking appliances are now widely used in many catering establishments, as they allow an optimal guidance of a cooking process by means of automated cooking programs, and also the time required for the operation is reduced. Cooking programs can handle a number of complex functions, such as: B. an automatic detection of the amount of charge in the cooking chamber and dependent guidance of a cooking program, as for example in the DE 195 11 621 C1 is described. Such cooking programs are usually provided by the manufacturer, since a user could be overwhelmed with the programming of complex cooking programs and often does not have the time for this.

From the generic US 2005/0204934 A1 is a multi-function cooker with a programmable control unit known which can be programmed via a keyboard of the cooking appliance. During programming, several separate functional elements of the cooking appliance, such as a blower, heating elements and a steam generator, are individually controlled, whereby the user can set within the cooking program the relative sequence and the operating time of said functional elements. The disadvantage here, however, is, firstly, that during programming the interaction of the separate functional elements with each other and their interaction with the food is not taken into account, which can lead to unsatisfactory cooking results. Secondly, only a trained and experienced person can perform the programming, since, for example, the manual adjustment of the operating time of said elements is usually done by a lengthy iterative adjustment process.

From the WO 96/07298 A1 Furthermore, a vending machine for cooking products is known, in which a cooking process is performed on preset cooking product specific cooking programs. It is provided that individual parameters of the cooking program specific cooking programs can be changed by an operator of the vending machine.

After all With the invention, a cooking appliance for performing proposed a method of the invention.

The invention is thus based on the surprising finding that the user of a cooking appliance can also program very complex cooking programs automatically by integrating previously stored intelligent cooking program modules within a cooking appliance programming environment into an individual cooking product-specific cooking program. The cooking program modules are used to take over complex control tasks, control tasks and / or functions for a cooking process, these cooking appliance functions can be divided into the following three groups: The cooking appliances functions of the first group are used for the detection and / or compensation of at at least one characteristic size of the cooking product loaded in the cooking chamber of the cooking appliance, such as a feed quantity, a cooking product caliber, a type of food item, a state and / or initial state of the item to be cooked, such as fresh or frozen, a turning point of food to be cooked, and / or a spatial distribution of the food in the cooking chamber. The cooking appliance functions of the second group serve to detect and / or compensate for at least one characteristic size of a cooking appliance element, such as a sensor to be inserted into a food, in particular a cooking process sensor, and / or an opening of a cooking chamber door. Finally, cooking equipment functions of the third group serve to guide an operation of a cooking appliance, such as hold-hold, over-crust operation, energy-saving operation, and / or cleaning and / or descaling operation.

These Functions are in the form of appropriate program modules from Manufacturer previously stored in the cooking appliance, so that a User no longer has to program the modules himself. Alternatively, the user can also use the program modules download an internet connection from a manufacturer's server.

So the user is allowed to use the cooking program modules during a program either directly call or optionally the cooking program module when calling at least one parameter and / or at least one data structure to pass the respective cooking program module to the wishes of the user adapt. A cooking program module performs automatically, in particular depending on the given Parameters and / or data structures, and for the user concealed a control or regulation of at least one cooking appliance function by. It is advantageously provided that the Modules also exchange data structures and / or parameters with each other can, for optimal guidance of a program or program step to ensure.

The Modules on a control or regulating device of the cooking appliance are executed, also communicate with sensors the cooking appliance for detecting actual values, for example the temperature, the humidity and / or the flow velocity the cooking room atmosphere, and with adjusting elements of the cooking appliance, comprising, for example, in each case at least one fan wheel, a heater, a steam generator, a steam exhaust and / or a Beschwadungseinrichtung.

On This way, the user can manually program cooking programs for the otherwise highly qualified specialist personnel would be necessary. In addition, by the integration of the prefabricated Cooking program modules in a cooking program a considerable time during cooking program creation compared to a conventional one Programming achieved. Because the user does not have the program modules must program itself, appropriate errors are added programming avoided.

A particularly user-friendly programming is made possible by that the user a cooking program or a cooking program step over an operating device of the cooking appliance, comprising a plurality Keys, in particular symbol keys, a screen and / or a Enter rotary knob for setting parameters of the program modules can.

Further Features and advantages of the invention will become apparent from the following Description, in the embodiments of the invention explained in detail with reference to schematic drawings in detail are. It shows;

1 a schematic sequence of a first cooking program, are involved in the present invention four program modules; and

2 a schematic sequence of a second cooking program, are integrated into the present invention, three program modules.

An exemplary structure of a first user-specific cooking program, which has been assembled according to a method according to the invention, is disclosed in FIG 1 shown schematically. Accordingly, the program consists of four program steps S1 to S4, which are executed one after the other within the temporal program sequence, characterized by the arrows between the program steps. If necessary, a user can program each individual program step himself, or at least use parts of a stored program. The cooking program modules M1 to M4 are optionally included in the program steps 1 each with a framed plus sign and a connecting line 10 . 11 . 12 . 13 is shown. The framed plus sign can be regarded as an interface via which, if necessary, a parameter and / or a data structure can be transferred.

During the first program step S1, a cooking chamber of a cooking appliance, not shown, is preheated with hot air at a temperature of, for example, 160.degree. Thereafter, a request to load the cooking chamber with food, consisting of a plurality of substantially similar Gargutstücken and optionally a sensor, in particular a cooking process sensor, to be inserted into a piece of food. For this purpose, a cooking chamber door must first be opened and finally closed become.

To Closing the cooking chamber door follows the second program step S2, in which the cooking space in a period of typically 5 min heated to a target temperature of 140 ° C of the cooking chamber atmosphere becomes. By feeding the cooking chamber with not preheated food the cooking space temperature drops initially and rises then after a characteristic time or with a characteristic one Temperature rise to the target temperature of 140 ° C on. The course of the temperature is dependent on the heat capacity of the food. After considering the heat capacity of the Garraums and the type of food can be in this way on the amount of food to be cooked and / or the Close the caliber of the food.

As in 1 can be seen, in the program step S2, the module for detecting and compensating the feed amount M1, also called load module, integrated. The integration takes place by simply calling the module, whereby no parameter is passed to this module M1 by the user. The module M1 automatically performs a detection of the amount of charge, in particular a load detection, in the manner described above. Depending on the amount of feed, the cooking process is performed during program step S2 and / or during all subsequent program steps S3 and S4. In each case, the temperature, the duration of the cooking program steps, a Beschwadungsaktivität, a fan speed and / or humidity in the cooking chamber are adapted to the determined by the module M1 feed amount.

advantageously, can by calling the module M1 on a device-specific Adaptation of the cooking parameters for different feed quantities be waived. In particular, can provide for the user the calculated amount of charge also the other program modules M3 and M4 for the purpose of optimized cooking process management as Parameters are passed.

During the program step S2, the spatial temperature distribution of the individual items to be cooked will also change, since the food to be cooked is cooking from outside to inside. The temporal progress of this spatial temperature distribution is with a cooking process sensor, as in the DE 100 61 821 C2 is described in detail, measured and provides a statement about the state of the Gargutstückes, which in turn is used for the Garprozeßführung. After loading the cooking chamber, it is therefore of interest to determine whether the cooking process sensor is plugged into a food or not. This check is made by the program module for detecting the state of the cooking process sensor M2, which was also included by the user in the program step S2. If the module M2 detects that the cooking process sensor was not correctly inserted into a piece of food, an alarm signal is activated, which indicates the user to the faulty connection of the cooking process sensor.

After the program step S2 follows the approximately 10-minute program step S3, in which the cooking chamber is heated by means of hot air to 160 ° C. As in 1 can be seen, the program module "Wendezeitpunkt" M3 is called by the user. This module, to which no parameter is passed to the user, calculates the turning point at which the pieces of food to be cooked, in particular meat and / or baked products, should be spatially turned to achieve an optimum state of cooking. When the turning point is reached, an alarm signal is issued to the user accordingly. For calculating the turning point, the module M3 can in particular fall back on the amount of charge calculated in module M1.

This is followed by the approximately 8-minute program step S4, in which the cooking chamber is controlled with hot air to a temperature of 175 ° C, for example. For reasons of saving energy, it may be useful to consider the heat already stored in the cooking chamber and food in the adjustment of the heat supply to the cooking chamber. Such a consideration of the stored heat makes the program module for performing an energy saving function M4, which has been included by the user in the program step S4. A more detailed description of this energy saving feature can be found in the non-pre-published DE 10 2007 036 513 , Compared to the temperature during operation without energy-saving function or with almost constant heat energy supply, the temperature will typically be reduced as the program module M4 is activated with increasing time. However, the reduced intensity of the heat input into the food can be compensated for example by an extended duration of the heat input. For this purpose, a remaining time for the cooking program step is first estimated by the program module M4 and subsequently adapted to the program step duration to achieve a desired Gargutzustandes accordingly. Optionally, the degree of consideration of energy saving can be transferred as a parameter when calling the program module M4. This parameter can be used to implement different intermediate positions between the two extreme settings "Energy saving function off" and "Maximum energy saving function".

A second exemplary user-specific cooking program, which according to a erfindungsge has been programmed in accordance with is 2 shown schematically. In a similar way as related to 1 described, the program consists of three program steps S10, S20 and S30, which are executed within the temporal program sequence in succession and are integrated in the cooking program modules M1, M4 and M5.

While a first cooking program step S10 again the cooking chamber preheated to a temperature of about 140 ° C, whereby by a Combination of hot air and steam an oven atmosphere is set with a moisture content of, for example, 60%.

To Loading the cooking space with food follows the approx. 20 minutes Program step S20, which also has a cooking chamber atmosphere with a moisture content of 60%. By the user were the program modules M1 and M4, which have already been described above, involved in the program step S20.

While of the last program step S30 is via hot air for about 10 minutes a dry cooking atmosphere produced at a temperature of about 180 ° C. From the user was the program module for performing an overcrusting function M5, whereby the module was given a parameter "Browning degree" when called. This parameter gives the desired tanning of the food after passing through the program step S30. The Module calculates the remaining time of the program step, which is used for Reaching the desired browning necessary is, and ends the program step after this time has elapsed.

numerous Further program modules are included in the invention. Here, the variety of possible Sort program modules into three groups.

A first group of program modules serves to detect a characteristic size of a food item loaded in a cooking chamber of a cooking appliance and to guide a cooking process as a function of said size. This may be not only the module M1, but also a program module for detecting and / or compensating a state of the food in the cooking chamber, determined in particular by the core temperature, the cooking value (C value), the hygiene, the sterilization value , the pasteurization value, the pH or the like. For example. For example, such a program module may be a C-value module that allows a cooking end to be specified when a percentage C value is entered, as in the case of the non-pre-published one EP 07 016 734 described. Alternatively, a sterilization module or pasteurization module can be used, which causes an automatic sterilization or pasteurization of a food by specifying a certain time and temperature. Another advantageous program module of the first group is used to detect and / or compensate for a distribution of the food in the cooking chamber. Another program module is used, for example, the detection and / or compensation of the nature of the food in the oven, determined in particular by the type of cooking, such as poultry, meat, fish, vegetables, baked goods or the like. Likewise, a program module for detecting and / or compensating the Gargutausgangszustandes, determined in particular by the cooking temperature, such as frozen or fresh, may be provided.

A second group of program modules deals with the recognition of a characteristic size of a Cooking appliance element and guiding a cooking process depending on this detected characteristic Size. As a representative of this group the module M2 has been previously described.

The program modules of the third group relate to the operation of a cooking appliance, as described above in connection with the module M3, M4 and M5. For example. In addition, a program module for detecting an opening of a cooking chamber door and / or for compensating a recognized cooking chamber door opening may be provided, wherein a cooking chamber door opening, comprising an opening angle and an opening period, for extending a cooking step, either continuously or only from exceeding a threshold value, may result , as in the context of DE 10 2005 020 744 B3 described. But also a program module for performing a cleaning and / or descaling operation is conceivable, for example, a cleaning program cleaning points can be assigned, such as, in the context of not previously published DE 10 2007 005 501 described. As a further program module, for example, a program module for carrying out a hold operation may be mentioned, in which the user passes the holding temperature and / or the holding period as parameters. With this module, for example, food can be kept warm at reduced temperature or cooked overnight.

Further possible program modules are conceivable.
