Description

 Control, regulation and operating device for a cooking appliance

The present invention relates to a control, and

Operating device for a cooking appliance. The invention also relates to a cooking appliance equipped with such a control, regulation and operating device and to a method for operating such a cooking appliance.

Due to the pressure prevailing in a steam or pressure cooker and the associated higher cooking temperature, the cooking time in such a pressure cooker can be shortened accordingly. Due to the so-called RGT rule (reaction rate-temperature rule) increases the

Cooking speed up to a factor of 4 compared to a non-pressurized cooking. However, this also means that delicate foods

can boil down comparatively quickly. In order for the user to be able to influence the respective cooking process, he is helped with the help of a

Spring mechanism of the internal pressure displayed in the pressure cooker, wherein the springs of the spring mechanism usually subject in their properties, both manufacturing tolerances and temperature fluctuations and thereby make a display relatively inaccurate. Furthermore, such spring-loaded systems operate with relative and not absolute pressure values, meaning that a pressure difference between outside and inside pressure is relevant. This circumstance is problematic, in particular due to the influence of weather conditions or due to different altitudes above the

Sea level for pressurized systems. Due to the inaccurate pressure display, there is always an unsatisfactory cooking result. The present invention is concerned with the problem of providing a control, regulating and operating device for a cooking appliance, by means of which also for laymen good cooking is made easier.

This problem is inventively by the objects of

solved independent claims. Advantageous embodiments are

Subject of the dependent claims.

The present invention is based on the general idea, a

Specify control, regulation and control device for a cooking appliance, which makes it possible to cook different foods with different Gardaten in one and the same cooking appliance simultaneously and yet individually optimally. The control, regulation and

Operating device in this case has an adjusting device, via which at least two different foods can be selected, which are to be cooked in the cooking appliance. The at least two different foods have, for example, different optimal cooking temperatures and each

different optimal cooking times, so that they could not be cooked together in a cooking appliance at the same time. The control, regulation and operating device according to the invention also has a data storage, in the food-specific Gardaten below

Consideration of RGT rule (reaction rate-temperature rule) are deposited. Likewise, a sensor device is provided for detecting at least one parameter influencing a cooking process. The core of the invention forms a microcontroller and / or microprocessor for

Control / regulation of the cooking process as a function of the selected food and in dependence on the respective food-specific Gardaten and the RGT rule, said microcontroller and / or

Microprocessor is also designed such that it starts from the Food with the longest cooking time determined each optimal insertion time for the food with the next shorter cooking time and displays a display device. Thus, if, for example, a recipe with different foods put together, they are first on the

One-piece device selected, whereupon then the microcontroller and / or microprocessor of the control, regulation and operating device displays that food, which must first be inserted into the cooking appliance. At the same time, the microcontroller and / or microprocessor can set an optimal cooking temperature for this purpose, which is then either set by the user at a stove or transmitted directly from the microcontroller and / or microprocessor wirelessly to the stove. At the beginning of the cooking process, the microcontroller and / or microprocessor determines the respective insertion times for the next food and indicates on the display device, when the next food, d. H. the one with the next shorter cooking time in which the cooking appliance has to be inserted. If this food has a different cooking temperature from the previously inserted food, the microcontroller and / or microprocessor can either define a common set cooking temperature or offer the user a selectable cooking time, for example the fastest or a gentle cooking time, for selection. The advantage of the control, regulation and control device according to the invention is clearly the one that the previously required by the user cooking expertise now of the control, and

Operating device is provided, which in particular a user can rely on skill deficiencies in cooking that all selected by him and arranged in the cooking appliance food are cooked individually and each optimally. In particular, this eliminates the need for conventional control circuits, such as testing, decision on the duration of the service, etc. The temperature profile actually occurring during the cooking process can be detected via the at least one sensor device, with which the microcontroller and / or microprocessor can calculate a dynamic adaptation of the respective optimal insertion times of the next food.

With the possibility of combining multiple (basic) foods into a prescription in the microcontroller and / or microprocessor, the user is assisted to complete all foods at the same time, particularly with regard to the question of when the optimal time for onset is and if necessary which amount of water is required, etc.

The individual foods can be compiled by the user to a recipe (Select + Confirm). This recipe can

 - be assembled individually by the user,

 - for future use under its own filename in

 Data memories are stored,

 - Loaded as already compiled recipe on the data memory

 (for example, as a download from a website),

If several foods are combined as prescriptions, each of these foods requires a specific amount of water for steam cooking or boiling in water. However, a mere addition of the respective amounts of water is not correct, since the steam is just an energy source and the

Water consumption therefore correlates only with the cooking time. The inventively provided microcontroller and / or microprocessor is able to calculate a combined amount of water. This can be done as follows, regardless of the order of food to be cooked:

The data memory stores every food with an associated set amount of water. Example: The user wants to cook 2 basic foods: potatoes and carrots, with the amount of water for potatoes: 1, 5 L; and the amount of carrots: 1, 0 L.

If the potatoes are first placed in the cooking vessel, then the required amount of water of 1, 5 L is added. Since the amount of carrots (= 1, 0 L) <1.5 L, the user is not prompted by the microcontroller and / or microprocessor to add more water. in the

In the reverse case, ie for carrots as the first food to cook, the added amount of water is 1, 0 L. Since the amount of carrots (1, 0 L) is smaller than the amount of water for potatoes (1, 5 L), the user of the Microcontroller and / or microprocessor prompted to add the difference 1, 5 - 1, 0 = 0.5 L of water. This functionality can also be used analogously for more than two foods. As a result, the user an important assistance function - and thus a relief is offered. In addition, the "success" in cooking and cooking processes is increased by ensuring the always correct amount of water. In particular, a "dry running" can be prevented.

Suitably, the microcontroller and / or microprocessor is designed such that it displays different completion times of the individual foods on the display device in selected foods with different cooking temperatures or a common and averaged

Completion time calculated all food arranged in the cooking appliance and then displays this via the display device. In the first case, the user must then remove the food displayed in each case from the cooking appliance on the basis of the respective individual completion times, whereas in the second alternative it receives a new common completion time of all foods, which, however, represents a compromise and does not necessarily correspond to the optimal completion time of each food. Such different completion times can also be set during the cooking process on the basis of an individual temperature profile, in which case the microcontroller and / or microprocessor will actually be replaced by means of the

Sensor device determined temperature profile, the individual

Adjusting production times.

In a further advantageous embodiment of the solution according to the invention different user profiles with different, especially individually selected, Gardaten are provided. Such different user profiles can be adjusted in particular via individually adjustable,

create customizable and storable degrees, so that with the control, regulation and control device a wide variety of people can achieve optimal cooking results adapted to their taste preference. It is conceivable here that different degrees of cooking can be set for different foods, since a person prefers meat, for example, but cooked vegetables only.

Suitably, the control, regulation and operating device has a base station and at least two each on the associated cooking appliance, eg. On the associated pressure cooker, attachable satellites that communicate wirelessly with the base station, wherein the setting device, the data memory and the microcontroller and / or microprocessor in the base station and the sensor device are arranged on the respective satellite. Through this

Embodiment, it is possible to individually control or regulate several cooking appliances with only a single base station and to look after.

Alternatively, it can also be provided that the control, regulation and operating device together with the adjustment device, data memory, microcontroller and / or microprocessor and sensor device completely on the cooking appliance

is arranged. In this embodiment, therefore, each cooking appliance has its own control, regulation and operating device, which of course may be able to wirelessly with each other

communicate.

Wireless communication between the individual satellites and the associated base station can take place, for example, via W-LAN, BlueTooth, GSM, UMTS, DEC and RFID, the respective abbreviations being explained in the claims. Especially so-called RFID chips have the advantage that they can be powered by radio waves with energy and thus require no own and self-sufficient energy supply. Of course, an alternative energy supply, for example. By PTC elements or solar cells conceivable. A W-Lan transmission of data in local networks and evaluation of the same is in principle conceivable.

Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated

Description of the figures with reference to the drawings.

It is understood that the features mentioned above and those yet to be explained below can be used not only in the respectively specified combination but also in other combinations or in isolation without departing from the scope of the present invention.

Preferred embodiments of the invention are illustrated in the drawings and will be described in more detail in the following description, wherein like reference numerals refer to the same or similar or functionally identical components. It show, each schematically:

1 a total of three cooking appliances in the form of cooking pots, each with an individual control, regulation and operating device,

2 a control, regulation and operating device with a

 Base station and each one arranged on the associated cooking device satellite.

According to FIG. 1, a control, regulation and operating device 1 according to the invention for a cooking appliance 2, for example a pressure cooker or a normal cooking pot which can be closed by means of a lid, has one

An adjusting device 3, via which at least two different foods are selectable to be cooked in the cooking device 2. In addition, the control, regulating and operating device 1 according to the invention has a designated data memory 4 in which food-specific cooking dates are stored, taking into account the so-called RGT rule (reaction rate-temperature rule). Likewise, the control, regulation and operating device 1 comprises at least one sensor device 5 for detecting at least one parameter influencing the cooking process, such as, for example, pressure and / or temperature. The core of the invention is a microcontroller and / or microprocessor 6 for data processing and control / regulation of

Cooking process as a function of the selected food and the RGT rule, wherein the microcontroller and / or microprocessor 6 is designed such that it determines from the food with the longest cooking time, each optimal insertion time for the food with the next shorter cooking time and a display device displays. The Display device may be formed, for example, in the manner of a display 10.

The control, regulation and operating device 1 makes it possible

to cook different foods with different cooking in one and the same cooking appliance 2 simultaneously and yet individually optimally. The at least two different foods usually each have different optimum cooking temperatures and each have different optimal cooking times, so that they can not be cooked together in a cooking appliance 2 at the same time. So if, for example, a recipe with

Assembled different foods, they are first selected on the setting device 3, whereupon then the microcontroller and / or microprocessor 6 of the control, regulation and control device 1 displays that food, which must first be inserted into the cooking appliance 2. At the same time, the microcontroller and / or microprocessor 6 can specify an optimum cooking temperature for this purpose, which is then set either by the user at a stove 9 or by the microcontroller and / or

Microprocessor 6 is transmitted directly wirelessly to the stove 9. At the beginning of the cooking process, the microcontroller and / or microprocessor 6 determines the respective insertion times for the next food and indicates on the display device, when the next food, d. H. the one with the next shorter cooking time, in which cooking appliance 2 must be inserted. If this food has a different cooking temperature from previously inserted food, the microcontroller and / or microprocessor 6 can either define a common set cooking temperature or offer the user a selectable cooking time, for example the fastest or a gentle cooking time. The advantage of the invention

Control, regulation and control device 1 is clearly the one that the previously required by the user cooking expertise now from the Control, control and operating device 1 is provided, which in particular a user with skill deficits in cooking can rely on all selected by him and in the cooking device. 2

arranged foods are cooked individually and each optimally. About the at least one sensor device 5 can during the

Garprozesses actually occurring temperature profile are detected, with which the microcontroller and / or microprocessor 6 can calculate a dynamic adjustment of each optimal insertion times of the next food.

In addition, the microcontroller and / or microprocessor 6 can either itself define a desired cooking temperature for selected foods with different cooking temperatures or offer a user a cooking time, for example the fastest or a gentle cooking time, for selection. The microcontroller and / or microprocessor 6 thus leaves the

Users have the choice between the complete adoption of the cooking expertise by the microcontroller and / or microprocessor 6 or co-decision by the user. This is also reflected in the fact that the microcontroller and / or microprocessor 6 determines different completion times of the individual foods or an average common completion time of all foods to be cooked for selected foods with different cooking temperatures and displays them via the display device.

The microcontroller and / or the microprocessor 6 can in this case the data required for the calculation of the insertion times from the data memory 4

remove. In the data memory 4, the individual Gardaten the

Food stored. Of course, the control, regulation and operating device 1 can also access or process the data stored in the data memory 4. With the possibility of putting together several (basic) food to a recipe in the microcontroller and / or microprocessor 6 is the

Assists users to complete all food items at the same time, in particular with regard to the question of when is the optimal time of loading and, if necessary, what quantity of water is required, etc.

The individual foods can be compiled by the user to a recipe (Select + Confirm). This recipe can

- be assembled individually by the user,

 - for future use under its own filename in

 Data memory 4 are stored,

 as an already compiled recipe are loaded onto the data memory 4 (e.g., as a download from a website),

If several foods are summarized as a recipe, the

According to the invention provided microcontroller and / or microprocessor 6 able to calculate a combined amount of water. This can be like in

general part of the description was carried out. As a result, the user an important assistance function - and thus a relief is offered. In addition, the "success" in cooking and cooking processes is increased by ensuring the always correct amount of water. In particular, a "dry running" can be prevented.

The sensor device 5 may in particular have a temperature sensor, such as, for example, an NTC or a PTC resistor, a pressure sensor and / or a fill level sensor, which determines a fill level in the cooking device 2. The individual degrees of cooking are individually adjustable, customizable and in the

Data storage can be stored, which allows individual user profiles to be created. In principle, there are two alternative embodiments of the inventive control, regulation and control device 1, namely that shown in FIG. 1 and the alternative shown in FIG. 2. In the case of the control, regulation and operating device 1 shown in FIG. 1, the latter, together with the adjusting device 3, display device, data memory 4, microcontroller and / or microprocessor 6 and sensor device 5, are arranged on the cooking device 2. Alternatively, has the control, regulation and control device 1 according to the apparatus in Fig. 2, a base station 7 and at least one attachable to the respective associated cooking device 2 satellite 8. Here are the

Adjustment device 3, the display device, the data memory 4 and the microcontroller and / or microprocessor 6 are arranged in the base station 7, whereas the sensor device 5 is arranged on the respective satellite 8.

The individual satellites 8 with each other and / or the satellites 8 and the

Base station 7 can communicate with one another, for example, via W-LAN, via BlueTooth, via GSM, via UMTS, via DEC or via RFID technology. It is conceivable that the control, regulation and control device 1, for example, also controls or regulates a heating power of a cooker 9, on which the respective cooking appliance 2 is turned off.
