Description

The present invention relates to a cooking appliance with at least one cooking chamber and with at least one heating device for heating the cooking product introduced into the cooking chamber. Furthermore, at least one control device for controlling the power of the heating device is provided, wherein at least one operating device, which is operatively connected to the control device, can be set by a user to set parameters for a cooking process. The present invention also relates to a method for operating such a cooking appliance.

For cooking appliances, a user can also set other options for self-assembled cooking programs and especially when using automatic programs depending on the equipment of the cooking appliance.

For example, it can be set whether, after the end of the cooking process, a rapid cooling of the cooking chamber should take place. This is particularly useful when cooking is to remain after cooking in the oven, but should not continue.

Furthermore, it can often also be set that the food to be cooked should remain in the cooking space after the end of the actual cooking time and should be kept warm.

The disadvantage, however, is that setting such options is often quite complicated and that a user usually has to click through complicated menu guides in order to put together the desired functions.

It is therefore the object of the present invention to provide a cooking appliance, which is easier to use.

This object is achieved by a cooking appliance with the features of claim 1 and by a method for operating a cooking appliance with the features of claim 10. Preferred developments of the invention are subject of the dependent claims. Further advantages and features of the invention will become apparent from the embodiments.

The cooking appliance according to the invention comprises at least one cooking chamber and at least one heating device for heating the cooking product introduced into the cooking chamber. Furthermore, at least one control device for controlling the power of the heating device is provided, wherein this control device is operatively connected to at least one operating device. Via the operating device, a user can set parameters for a cooking process.

It is also possible to set whether the food to be cooked should be taken directly or later at the end of the cooking process. In this case, the control device is suitable and designed to adjust the parameters for the cooking process such that the cooking result at a later removal substantially corresponds to the cooking result in an immediate or direct removal.

According to the invention, certain parameters for a cooking process in the control device can be set by the user via the operating device. In this case, according to the invention, a parameter is understood to mean in particular a specific power of the heating device and preferably the temperature of the cooking chamber and / or the time or the cooking time. In particular, it can also be set as a parameter whether rapid cooling is desired at the end of the cooking process, whether steam is to be introduced into the cooking chamber or the moisture is to be regulated during the entire cooking process or during a cooking section and / or if the cooking chamber door is after the cooking process sections or completely at least temporarily to be opened.

Preferably, at least one parameter or a selection of parameters for the cooking process is set via the selection of an automatic program. For example, it is possible that the simple selection of an automatic program sets, for example, the desired temperature and the residence time or the cooking time of the food to be cooked.

To set the parameters and the option of whether the food is to be taken directly or later, the operating device preferably comprises operating elements, which can be provided, for example, via a touchscreen.

That is further adjustable, whether the food is to be taken directly or later, according to the invention means in particular that both before the selection of parameters for a particular cooking process, as well as after the selection of parameters can be determined by a user, if the food immediately, So immediately after the food end, or should be removed later.

The cooking appliance according to the invention offers many advantages. A significant advantage is that a cooking appliance is made available to a user in which he can determine via a simple selection when he wants to remove the food after the end of the cooking process.

If the food is to be removed immediately after the cooking process, this can be specified by the user. Preferably, in the case of a lack of selection for the subsequent or direct removal, a cooking cycle is automatically carried out in which a direct removal is planned.

However, if a user wants to remove the food only later, he can easily adjust this via the operating device in the control device. Then the previously set cooking process or then one or more parameters set for the cooking process is adjusted by the control device such that the cooking result in the subsequent removal essentially corresponds to the cooking result in the direct removal.

Thus, a user is provided with a particularly comfortable to use cooking appliance, in which the removal time for a ready-cooked food can be set or determined very flexible.

Preferably, at least one switch is provided, via which a subsequent removal is adjustable. A switch is understood in particular to be a type of pushbutton and / or control toggle, that is to say a hardkey. A softkey and / or a virtual switch can also be provided. Particularly preferred is a switch or a plurality of switches are provided on a touch panel or the touch screen, via which parameters for a cooking process and / or the subsequent and / or direct removal can be set.

In appropriate embodiments, after the beginning of the cooking process, it is possible to set the food to be removed later. With such a configuration, a user is given the opportunity even after the start of the cooking process to delay the removal of the food. This offers the particular advantage that a user can still set the later removal even if he forgot it before starting the cooking process or even if, for example, the serving time has moved backwards.

Preferably, a removal time is adjustable. In such a configuration can be set by a user explicitly when the food is to be removed from the oven or finished cooking should be. Here it can be adjusted in particular that the food to be cooked, for example, in one hour and / or at 13.30 clock ready or should be removed from the oven.

It is preferably adjustable at a later removal, whether the food is to be kept warm or removed cooled. Here can be adjusted in particular that the food to be kept warm or to be taken for immediate consumption from the oven. This is to be understood in particular that the food is not only lukewarm, but has a certain consumption temperature, so that the food can be served ready for consumption at a suitable temperature despite a later removal. In particular, the food to be removed at a later warm held removal at least 10 ° C above ambient temperature from the oven. Under a later cold removal of the food is particularly preferred that the food during removal in the Essentially completely cooled. A cold subsequent removal is particularly suitable for example in the preparation of cakes. This can then be cooled automatically after the cooking process, so that the cake can remain in the cooking chamber even after the end of the cooking process and is cooled there. Thus, even at the later cold removal, the cooking result substantially and in particular completely corresponds to the cooking result, which would be present if the cake is removed from the cooking chamber immediately after the cooking process and cools outside the cooking chamber.

The setting whether the food is to be kept warm or removed cold at a later removal from the oven, can preferably be adjusted via a switch. The setting by means of a switch is to be understood in particular such that a user can adjust the selection simply and quickly by pressing a switch, by turning a switch or by operating a softkey or by touching a virtual switch on a touch panel.

Particularly preferably, the setting of a later removal is blocked if the same cooking result is no longer achievable. Thus, a subsequent removal is no longer selectable in particular when the cooking process has already progressed so far that the food to be cooked overcooked at a later removal, so can not be removed with a satisfactory quality from the oven. This ensures that a user can not set the subsequent removal after the start of the cooking process, if the same cooking result is no longer achievable compared to the immediate removal.

Preferably, at least one sensor device is provided, wherein the data obtained by means of the sensor device are taken into account in the adaptation of the parameters. In this case, in particular, a temperature sensor in the cooking chamber and / or a temperature spit in and / or on the food and / or a moisture sensor can be used to control the cooking appliance such that the cooking result at the later removal essentially corresponds to the cooking result at an immediate removal.

In expedient refinements, at least one steam generating device is provided, wherein steam can be conducted into the cooking chamber in order to achieve the same cooking result. In such an embodiment, for example, the drying of the food can be prevented by the moisture in the oven is adapted in a later removal so that the food does not dry out and yet an attractive and in particular compared to an immediate removal at least almost identical or similar surface properties having.

In expedient developments, the control device replaces at least one cooking section of the cooking process with at least one modified cooking section. It is under a Cooking section understood a certain period of cooking, with certain parameters are set for this period. In this case, a certain cooking section is preferably replaced by a modified cooking section by the control device, wherein the replaced and the modified cooking section preferably correspond in effect. Thus, for example, a cooking section with a certain period of time and a specific set temperature can be replaced by a particularly longer cooking section with a correspondingly lower set temperature, so that the cooking result at a later removal essentially corresponds to the cooking result with an immediate removal.

The inventive method is suitable for operating a cooking appliance, as described above. In this case, certain parameters are set to a cooking process by a user via the operating device. Furthermore, it is set whether the food is to be removed directly or later at the end of the cooking process, wherein the control device adjusts the parameters for the cooking at a later removal in such a way that the cooking result at a later removal substantially corresponds to the cooking result in a direct removal ,

In the method according to the invention, it is preferably also possible that a user does not always have to adjust whether he wants to remove the food directly or immediately. If it is not explicitly set or selected by a user that he would like to remove the food later, then the immediate removal of the food after the end of the cooking process is preferably automatically selected for the cooking process.

In this case, the setting whether the food is to be removed directly or later, adjustable before and / or after the start of the cooking process. This makes it particularly flexible for a user to specify the removal of the food or the time of completion of the food.

Appropriately, a warning or a backup is provided so that a subsequent removal is no longer adjustable when the cooking process is too advanced and / or a subsequent removal would affect the quality of the cooking result. In particular, a subsequent removal can no longer be set if it is no longer possible to achieve the same result of the cooking process at a later removal compared to an immediate removal.

Advantageously, data of at least one sensor device are taken into account in the adaptation of the parameters, whereby the cooking process is regulated in such a way over the data, for example a humidity sensor and / or a temperature spit, that an optimal cooking result is achieved even at a later removal.

The method according to the invention also offers many advantages. In particular, it allows a user in a simple way to decide whether the food should be removed immediately or later from the oven.

The parameters for the cooking process are preferably set via the selection of an automatic program. Thus, it is easily possible for a user to quickly set even complex cooking processes, where he also gets the opportunity to decide whether he wants to remove the food directly after the cooking process or even later by a simple choice.

For a later removal, it is particularly preferred to select whether the food to be cooked is to be removed from the cooking chamber when it is warm or cooled. Hot refers in particular to a subsequent removal for immediate consumption of the food. Then it is particularly preferred that the food is not only lukewarm, but ready for consumption or we finished cooked can be removed from the oven. A cooled removal is to be understood in particular as the removal of the completely cooled food. In this case, according to the invention, in particular, an active cooling of the cooking chamber can be made in order not to continue the cooking process too late in a later removal. For this purpose, in particular a blower can be switched on, the cooking chamber door can be partially and / or completely and / or temporarily opened and / or the temperature can be adjusted down to the end of the cooking process.

Preferably, at least one cooking section of the cooking operation is replaced by at least one modified cooking section, wherein the replaced cooking section and the modified cooking section correspond to the cooking result. The modified parameter to the modified Garabschnitt selects the control device in particular automatically, for example, a certain time is replaced at a certain temperature by a modified Garabschnitt, which is preferably longer but for a lower temperature.

In preferred embodiments, the controller adjusts the power of the heater for later removal at least temporarily. It is particularly preferred that the power of the heater is adjusted in the modified cooking section such that the oven temperature is set to 40 ° C to 80 ° C. This ensures that, depending on the food, over-cooking is avoided and the food is still kept warm for consumption.

Further advantages and features of the present invention will become apparent from the embodiments, which are explained below with reference to the accompanying figures.

FIG. 5

a further purely schematic representation of the menu of the operating device of a cooking appliance according to the invention.

In FIG. 1 is purely schematically a cooking appliance 1 according to the invention shown in a front view. The cooking appliance 1 shown here is configured as an oven oven 100, which has a cooking chamber 2 which is closable by a cooking chamber door 14.

The cooking chamber 2 is further associated with a heater 3, via which the introduced into the cooking chamber 2 Gargut can be heated or cooked. For setting or for controlling the heating device 3, a control device 4 is provided, which can be operated via an operating device 6. By means of this operating device 6, user can set parameters 7, 8 and other options for a cooking process. By way of the operating device 6, parameters 7, 8 can also be predefined, for example, via the selection of an automatic program.

The operating device 6 is executed in the embodiment shown as a touch panel or touch screen 22, wherein a user on this touch panel 22, a menu 24 and a user interface 25 for setting cooking program, parameters 7, 8 or other functions available.

To set parameters 7, 8 such as the power 5 heater 3 and / or the time 23 or a desired cooking time, a user on the touch panel 22 and on the user interface 25 so-called switch 9 actuate, the user by pressing this Switch 9 certain functions on and / or deselect and / or certain parameters 7, 8 can set.

At the in FIG. 1 illustrated embodiment of the cooking device 1 according to the invention, a user via the control device 6 or via the pressing of certain switches 9 in the menu 24 specific automatic programs and / or individual parameters 7, set 8 for a particular cooking. Furthermore, the user can specify via a corresponding switch 9 or via appropriate switch 9, whether the food to be taken after the end of the cooking process directly or only later from the cooking chamber 2.

For this purpose, the control device 4 is suitable and designed to adjust the set parameters 7, 8 such that the cooking result at a later removal substantially corresponds to the cooking result at an immediate removal.

In the embodiment shown, the cooking appliance 1 shown further comprises a sensor device 10 and a steam generator device 11. In the adaptation of the cooking program at a selected later removal, the control device 4 in the embodiment shown, the data of the sensor device 10 to the parameters 7, 8 so adjust that the cooking result at a later removal corresponds to the cooking result in an immediate removal. For this purpose, the sensor device 10 may be designed, for example, equipped as a temperature sensor or as a temperature spit.

Furthermore, the control device 4, for example, the steam generating device 11 drive and introduce steam into the cooking chamber, so that the moisture in the cooking chamber 2 is regulated such that the cooking result at a later removal according to the cooking result in an immediate removal.

In FIG. 2 purely schematically shows the comparison of a cooking process with immediate removal and shown at a later removal. The food to be removed during the later removal cold from the cooking chamber 2.

Parameter 8 is plotted on the X-axis, whereby the time 23 or cooking time is indicated here. Parameter 7 is plotted on the Y axis, which corresponds to the power 5 of the heating device 3 or, in the exemplary embodiment shown here, to the cooking chamber temperature 15.

The curves show that both in the direct or immediate removal as well as in the subsequent removal of the cooking chamber temperature 15 initially increases in the cooking process shown and then held for a long time at a level. The removal time 16 indicates the end of the cooking process in a direct removal of the food. The dashed line indicates the subsequent cooling of the cooking chamber 2. In such a program, the food is taken directly from the oven, for example, to serve it hot immediately.

The second curve shows the course of the cooking process in a later removal, if the user has also set that he wants to remove the food later and cold from the oven.

Here, the removal time 16 moves back to the removal time point 17. When removing the food at the removal time 17, the finished food but should be removed cold, which can be adjusted via a switch 9 in the controller 3.

So that the food can be removed cold at a later removal at the time of removal 17 and still has the substantially same cooking result compared to an immediate withdrawal, the cooking section 12 of the actual cooking process is replaced by the control device 4 by a modified cooking section 13. In this case, the control device 4 controls the parameters 7, 8 such that the active power 18 of the actual cooking section 12 and the active power 19 of the modified cooking section 13 essentially correspond. This ensures that there are approximately the same cooking results both at the removal time 16 and at the later removal time 17.

In addition, the parameters 7, 8 were adjusted during the cooking process in such a way that the cooking chamber temperature 15 at the time of removal 17 has already dropped quite sharply. So the food can be removed cold or almost cold. Under cold is understood in particular that the food has cooled down so far that it no longer continues, so that the cooking result does not change. Such an approach is advantageous, for example, when baking cakes. So can be set by pressing a button that the cake should remain in the cooking chamber 2 after the end of the cooking process. For this purpose, the program is modified so that the cake cools in the oven and is not over-cooked or dry.

In FIG. 3 a comparison of three program sequences for a cooking process is shown. Here, the immediate removal and the subsequent removal of the food in the warm-held state and in the cooled state are shown here.

The actual cooking program ends with the immediate removal at the removal time point 16. In the embodiment shown, the subsequent removal ends with cooled food at the removal time 17 and the subsequent removal, in which the food is kept warm ends at the removal time 26th

In order to achieve the same cooking result for all three options, an actual cooking section 12 is replaced by the control device 4 during the cooled subsequent removal by a modified cooking section 13. In this case, the active power 18 of the actual cooking section 12 and the active power 19 of the modified cooking section correspond 13. Thus, the cooking result also corresponds to the removal time 17, as already in FIG. 2 shown, the cooking result of the immediate removal at the removal time 16.

If the food to be cooked is to be kept warm during a later removal or taken out of the cooking chamber 2 at the ready-to-serve temperature, the cooking section 12 is replaced by a modified cooking section 27. In this case, the effective powers of the program sections correspond, so that the cooking result with a warm-held removal at the removal time 26 essentially corresponds to the cooking result with an immediate removal at the removal time 16.

In contrast to the curve during a cold later removal of the food, the cooking chamber temperature 15 is lowered earlier in the embodiment shown. Furthermore, the effective powers 20, 21 correspond to each other so that a desired cooking result is present at the time of removal 26.

In FIG. 5 is purely schematically illustrated the operating device 6 of a cooking appliance 1 according to the invention. Here you can see the menu 24 and the user interface 25, via which automatic programs, parameters 7, 8 or other functions can be set. For this purpose, a user can simply press on the user interface 25, where he is offered variable depending on the menu 24 different switches 9.

It can be seen that over the touch panel 22 different modes, the cooking time and the cooking temperature can be adjusted. Furthermore, it can be optionally set when a cooking process should begin or when the food should be cooked.

In the right section can be seen in the menu 24, that there different variants of the removal of food can be set. This section of the operating device 24 is in FIG. 5 shown in more detail.

Here it can be seen that a user with regard to the removal of the food after cooking can choose three options. First, it can remove the food immediately after the end of the cooking process, the cooking chamber 2 is cooled after removal.

A second option is that the food is removed later and the cooking chamber 2 is cooled. This corresponds to a later removal of the food, wherein the food is removed in the cooled state. This is advantageous, for example, when baking cakes. Thus, it is possible that the cake remains in the oven after the end of the cooking process, wherein the cooking chamber 2 is particularly quickly cooled after the end of the cooking process, so that the cake can remain in the oven without the cooking result is changed.

The third option is that a subsequent removal takes place while the food is kept warm. In this case, the food is kept in particular at a consumption temperature, so that the food is suitable despite a later removal for immediate consumption.

The three options can be set via switch 9 in the menu guide 24 or via the user interface 25 via the operating device 6. Thus, a cooking appliance 1 is provided to a user, with which he can set in a particularly simple manner, whether he wants to remove the food immediately after the cooking process or whether a subsequent removal of the food with a comparable cooking result is desired.
