EP2872830B1 - Method for displaying parameters of a cooking process, and display device for a cooking appliance - Google Patents

Description

The invention relates to a method for displaying parameters of a cooking process. The invention further relates to a cooking appliance display device.

Modern cooking appliances for professional use, for example, in canteens and restaurants, can automatically run a variety of cooking programs to reproducibly cook different foods. An operator can choose between the different programs and also make specifications regarding the desired final state of the cooked product. For example, a cooking program "roast pork" can be selected, in which the roast pork at the end of the cooking program has the desired core temperature with a crispy crust.

It is known from the prior art that the cooking appliances, with which such cooking programs can be performed, display to the operator different information about the progress and progress of the cooking process. The most important parameter here might be the remaining time or the target time of the cooking program, so that the operator knows when the product has finished cooking. However, in view of the complexity of the cooking programs offered by modern cooking appliances, it is not easy to clearly provide the operator with the essential information needed for operating the cooking appliance and integrating the cooking appliance into the rest of the kitchen processes and on the other hand to inform the operator with information about which steps are currently taking place in the cooking process. This is particularly relevant in intelligent cooking processes in which the cooking process is automatically modified on the basis of detected parameters in order to achieve the result desired by the operator. For example, the cooking appliance can detect on the basis of the course of the core temperature, whether in the example considered here roast pork is a large or small caliber in the oven. Accordingly, the cooking time and / or the cooking space temperature can be adjusted. Such adjustments should be communicated to the operator in a clear manner, otherwise it is difficult to understand why, for example, a remaining cooking time of 2 hours is displayed at the beginning of the cooking process, but after the first 20 minutes of the cooking process suddenly a remaining cooking time of 2 hours 15 minutes was calculated. The previously known displays for cooking appliances are not able to offer the required information to an operator clearly.

The object of the invention is to provide a method for displaying parameters and a display device, with the or a user despite the variety of information that arise in modern, especially intelligent cooking appliances during operation, the overview of the currently running cooking process and thus a complete understanding of the cooking process is made possible.

To achieve this object, a method for displaying parameters of a cooking process is provided according to the invention, in which an information window is provided within a display window, in which an applied Garintelligenz is displayed temporarily. Furthermore, a cooking appliance display device is provided, with which various parameters and steps of a cooking process are displayed and made accessible to an operator for interaction, characterized in that an information window is provided, in which a currently applied cooking intelligence is displayed.

The invention is based on the recognition that the cooking intelligence applied in an intelligent cooking process can lead to confusion of the operators, since they can not understand why and in what way such cooking intelligence influences and alters the cooking process.

"Garintelligenz" means an automatically running change of the cooking process due to an automatic detection of a parameter, wherein the change of the cooking process is calculated by the control of the cooking appliance as a function of the determined parameter. A cooking appliance with cooking intelligence regularly checks parameters independently by means of sensors and adjusts the cooking chamber climate or regulates the functions of the appliance regardless of the starting point of the food to reach the targets. A simple example of a cooking intelligence is an adaptation of the cooking time (or target time) depending on the detected caliber of a piece of meat to be cooked. If, as provided for by the invention, the applied cooking intelligence is displayed, it is understandable for an operator why "suddenly", ie after the caliber detection, a later end time for the current cooking process is displayed than at the beginning of the cooking process.

It is preferably provided that other information within the display window is visually withdrawn when a cooking intelligence is displayed. In this way, the attention of the operator is immediately directed to the currently applied Garintelligencez; the possibly very many other information that is currently not relevant, are "hidden".

To immediately illustrate the effect of the currently applied cooking intelligence to an operator, a temporarily applied cooking intelligence may be visually linked to an indicated cooking process parameter that is affected by that cooking intelligence. For example, a caliber detection can be linked to the cooking duration and / or the end time of the cooking process.

For the optical linking, an arrow, a light band, marker points or consecutively activated points can be used. Thus, a kind of optical road can be formed, which leads from the Garintelligencez to the parameter influenced by this.

The clarity over the entire cooking process can be increased if in the further course of the cooking process to be used Garintelligenzen be displayed in a display field. The display panel then forms a preview area in which the operator can find out which cooking intelligence is still being used in the further course of the cooking process.

To improve the clarity, it may also be provided that cooking intelligence already applied in the cooking process that is already in progress is displayed in a display field. This display field represents a storage folder, from which the operator can see which cooking intelligence has already been "processed".

According to a preferred embodiment, it is provided that the information window is displayed as a function of at least one cooking process parameter at different positions within the display window. As a result, additional information can be offered intuitively.

It is preferably provided that the distance of the information window from the lower edge of the display window on the temperature depends, in particular is substantially proportional to the temperature. In this way, an operator can immediately detect whether cooking is being done at high temperature or at low temperature. In addition, the temperature used can be specified exactly in a temperature display.

According to a preferred embodiment it is provided that between the information window and the lower edge of the display window, a bar is displayed, which contains information about the currently used cooking chamber atmosphere. Apart from the clearly offered additional information about the cooking chamber, the bar can also be used to visually divide the display window into different areas that are assigned to different phases of the cooking process. An area to the left of the bar can be assigned to already completed cooking process steps and cooking intelligences, an area to the right of the bar can be assigned to the remaining cooking process steps and cooking intelligences, and the center area of the display window formed by the bar can be used to display the current running cooking process step and the currently applied Garintelligencez be used.

• FIG. 12 a display device according to a sixth embodiment.

In FIG. 1 a display device 10 is shown having a display window 12. There are three display areas on it, namely a preview area 14, a now area 16 and a done area 18. Generally speaking, the now area is a middle area of the viewport that extends from top to bottom. The preview area is the right vertical edge portion of the viewport, and the done area is the left vertical edge portion of the viewport.

In the preview area 14, the cooking process steps of a selected cooking process are displayed in the form of fields 19, which still have to be processed. Here, the steps D, E, F and G are shown schematically. In the now area 16, the currently running cooking process step is displayed. It deals this is the step C. In the completed area 18, the already executed cooking process steps are shown, here, the steps A and B.

The currently running cooking process step is assigned an information window 20 in the now area, which is displayed at a variable distance from a base level. The basic level is determined by the level at which the currently running cooking process step is displayed. In the information window 20, all the information that is relevant in connection with the currently running cooking process step can be displayed. In particular, these are information which is represented as text, image or combination information T and which relate to the cooking intelligence of the cooking process, ie automated corrections. For example, could be displayed in the information window 20 that the cooking time was adjusted due to the detected caliber of food to be cooked (Garintelligence III).

In order to give an operator the opportunity to obtain additional, more detailed information on a currently applied cooking intelligence, a pop-up feature may be provided. Upon request, for example by pressing a key or selecting a field, supplementary explanations appear on the context and effects of the currently used Garintelligencez.

A beam 22, which represents an optical separation between the preview area 14 and the completed area 18, is defined between the currently running cooking process step shown in the now area 16 and the information window 20. However, the beam 22 not only serves to establish a direct connection between the currently running cooking process step and the information window 20, but the bar 22 is also used to indicate the current operating mode, for example hot air, steam or a combination of hot air and steam , For example, in a hot air / steam combination mode, the beam 22 may be split, as shown in FIG FIG. 1 is shown. Depending on the proportion of steam, the bar is displayed with a symbol H for hot air and a symbol D for steam.

In the upper area of the display window 12, two display panels 26, 30 are provided, of which the display panel 30 is arranged in the preview area 14 and the display panel 26 in the finished area. These two display panels 26, 30 are used to display the cooking intelligence still to be used during the cooking process (these are schematically shown in the display window 30 as cooking ingredients IV and V) as well as the already used cooking intelligence (these are schematically shown in the display window 26 as the cooking intelligences I and II shown).

In addition, further display fields 24 and 28 may be provided, in which further relevant information can be displayed. Thus, for example, in the display panel 24, the name of the current cooking process can be displayed, for example "crusty roast". In the central display panel 28, for example, the remaining cooking time of the running cooking processes can be displayed.

Below the display window 12, an information window 32 is provided, in which additional information can be displayed. Here, a start button for starting a selected cooking process may be provided or information about the remaining operating time until a cleaning cycle is recommended.

The display device 10 may be designed as a touch display, so that different selections can be made directly by touching the surface of the display device. Alternatively or additionally, a further input element may be provided, for example a control wheel.

In the case of a running cooking process, all individual cooking process steps of the selected cooking process are displayed in the preview area. As soon as a step begins, its field 19 is moved into the now-area 16 and displayed as the currently running cooking process step. At the same time, in the information window 20, those information that is associated with the currently running cooking process step can be displayed. As soon as the currently running cooking process step has been processed, it is moved to the done area 18, and the next cooking process step "slides" into the now area 16.

Analogous to the various cooking process steps, the currently relevant cooking intelligence is moved from the display panel 30 in the preview area 14 in the now-area 16 and from there, when the associated cooking process step is completed, in the display panel 26 in the done area.

In FIG. 2 is the display device of FIG. 1 shown, where currently the penultimate cooking process step expires. By comparison with FIG. 1 It can be seen that now the information window 20 is located much lower than in FIG. 1 , As a result, an operator immediately recognizes that a lower cooking chamber temperature is currently being used. In addition, the bar 22 is now fully executed with the symbol for steam, so that the operator recognizes that currently a mode with maximum steam content is used.

It can also be seen that meanwhile the last Garintelligence is active. All previous cooking intelligences are in the done area 18, and in the preview area 14 no cooking intelligence is displayed anymore.

In the Figures 3 and 4 a second embodiment is shown. For the features known from the first embodiment, the same reference numerals are used, and reference is made to the above explanations in this respect.

The difference between the first and second embodiments is that, in the second embodiment, the display window 28 for the remaining cooking time is integrated in the information window 20. The remaining cooking time may be similar to an expiring clock in the manner of a circle segment, in which the distance between a "pointer" 29 and an end position in the 12 o'clock position decreases. In addition, the remaining cooking time can also be specified explicitly (see the symbolized display xy in FIG. 3 or x in FIG. 4 ). Furthermore, similar to the first embodiment, a concrete text information T associated with the currently executing cooking process step may be displayed within the display of the remaining cooking time, for example, a current correction made by a cooking intelligence.

In the same way as in the first embodiment, the display panel 28 is displayed at a variable distance from a base level (see comparison of the Figures 3 and 4 ), and the bar 22 is used to graphically represent the currently used mode of operation.

In the Figures 5 and 6 a third embodiment is shown. For the features known from the preceding embodiments, the same reference numerals are used, and reference is made to the above explanations in this respect.

In the third embodiment, the information window 20 is executed as in the first embodiment. Concretely, a text information T is shown at a variable distance from a base level. Furthermore, the bar 22 extending between the information window 20 and the base level is used to display the current mode. The remaining cooking time is displayed in a separate display field 28, similar to the first embodiment. However, this is similar to the second embodiment carried out in the manner of a clock, which represents the remaining Restgarzeit by means of a pointer 29, which approaches with clocking cooking process in the clockwise direction of the 12 o'clock position.

In FIG. 7 a fourth embodiment is shown. This is based on the first embodiment, but the different cooking process steps of the cooking process are shown differently. In the fourth embodiment, no separate fields are used, which are moved in the manner of tabs from the preview area 14 via the now-area 16 in the done area 18, but the cooking process steps are as contiguous fields of a continuous process queue executed. The process queue with its fields 19 migrates from the preview area 14 to the done area 18, wherein the currently running process step is located in the now area below the bar 22.

In FIG. 8 1, a state of the display device 10 is shown, which can be selected when certain parameters are currently being changed due to running Garintelligenzen. In the example shown, the cooking process step B has resulted in that the residual cooking time shown in the display field 28 has been modified (cooking intelligence II). This is immediately highlighted to an operator in that, apart from the currently running cooking process step B and the display panel 28 all others Information were optically withdrawn, that is pushed into the background (here represented by the fact that the other fields are shown in dashed lines) and that a highly visible arrow extends from the currently running cooking process step B toward the display panel 28. Alternatively, the information that is currently not relevant can be optically withdrawn by being grayed out.

The link between the cooking intelligence and the changed parameter can also originate from the cooking intelligence, as in FIG. 9 shown. There is symbolized that due to the currently applied Garintelligence II, the remaining guard period was changed. The optical link can be effected by means of an arrow, a chain of marking points, a light band or moving points, for example in the manner of successively activated LEDs. At the same time, the further information can be "hidden", for example gray, in order to direct the focus of the operator to the effect of the cooking intelligence.

The applied Garintelligenzen can also have more profound effects than a mere modification of Garparametern. It is also possible that cooking process steps are newly added, for example, when a caliber detection leads to the realization that due to a particularly large caliber, another cooking process step is necessary. These can also be represented by means of the display device, as in FIG. 10 shown. Here an operator is signaled by an arrow or similar optical markings that a further cooking process step has been included in the process chain.

In FIG. 11 a further embodiment of a display device 10 is shown. The display window here has a semicircular shape, along the curved outer edge three different displays are arranged side by side. On the outside there is an indication of the temperature. Due to the angular range over which extends, for example, a color highlighted area 60, an operator can immediately intuitively detect whether just a high oven temperature or a low oven temperature is used. It is also possible to adjust the color of the area, for example blue at low temperature and red at high temperature.

Immediately within the temperature display is the here curved curved bar 22, which symbolizes the cooking chamber atmosphere. Again, directly inside is a symbolized display of the remainder of the guard, which uses the pointer 29 already known from the second or third embodiment. This wanders, for example, from the far right at the beginning of the cooking process over the middle to the left. Centrally below these displays are the preview area 14, now area 16, and done area 18, which show the various cooking process steps. Furthermore, display fields 30, 20 and 26 for displaying the Garintelligenzen available.

In FIG. 12 a sixth embodiment is shown in which the display device is designed as a circle. Again, a preview area 14, a now-area 16 and a done area 18 are delimited. The various cooking process steps are carried out along the periphery of the display device and are shifted therebetween between the different regions 14, 16, 18. Similarly, the Garintelligenzen be moved from the display panel 30 via the information window 20 in the display panel 26. The indication of the residual duration is also effected here via a pointer 29.

Notwithstanding the embodiments shown, the display panels 26, 30 may also be arranged at other locations of the display window, for example all on one side.

Furthermore, it can be provided that in the preview area and in the completed area not all still to be processed or completed steps are displayed, but for better clarity, only some or just the next respectively the last processed.

In all embodiments, in the information window 20, when the currently applied cooking intelligence is displayed, it may also be displayed which "insight" the cooking intelligence has received based on the sensors it interrogates. For example, it may be indicated (in the form of a pictogram, in plain text or otherwise) which caliber has been recognized, that a partial load has been detected, that a particular condition of the food has been detected, eg deep-frozen) This increases the acceptance by the operator as he can ensure that the adjustment of the cooking process parameters is based on product characteristics that have been correctly recognized by the cooking appliance.
