Description
Technical Field
The present invention relates to a method and a control device for controlling at least one function of a household appliance.
Background
In order to operate the functions of a household appliance, it is known to perform an operation of the household appliance by means of a gesture detection unit. Such a device with a gesture detection unit is described for example in DE 10 2014 007 172 A1. In the space illuminated by the first household appliance, which is the range hood, a posture for operating the other household appliance can be detected.
In addition, it is known in modern range hoods to use air quality sensors which regulate the range hood in accordance with the currently prevailing air composition. Once the air composition changes, the sensor reacts. If the user opens the lid, the fan level is adjusted once the elevated smoke passes the air quality sensor. The appliance can thus only react after an event has occurred.
Disclosure of Invention
The object of the present invention is therefore to provide a solution which at least reduces the disadvantages of the prior art.
The invention is based on the knowledge that this object can be achieved by monitoring the flow of the cooking process, predicting the environmental conditions to be expected, and controlling at least one function of at least one household appliance accordingly.
According to a first aspect, the invention thus relates to a method for operating at least one function of a household appliance. The method is characterized by detecting at least one decision criterion, evaluating the at least one decision criterion, predicting at least one environmental condition of the at least one household appliance based on the evaluation, and controlling at least one function of the at least one household appliance based on the prediction.
According to the invention, the household appliance is, for example, a kitchen range or a range hood. Preferably, a control device, which may also be referred to as a module and preferably implements the steps of the method according to the invention, is provided in or in connection with one of the household appliances.
The value or state that can be detected by the control unit is called a decision criterion. The evaluation of the at least one decision criterion may be a comparison with a threshold value or a previously detected value. According to the invention, a unique decision criterion can be evaluated. But it is within the scope of the invention to evaluate at least two decision criteria. The decision criteria can be evaluated individually or jointly. At least one environmental condition of the at least one household appliance is predicted based on a result of the evaluation of the at least one decision criterion. The prediction may be performed by using an algorithm. The state to be expected in the region of at least one household appliance is referred to as the environmental condition. The environmental condition may be, for example, the air composition in the area of the hood or the state of the food on the cooktop. At least one function of the at least one household appliance is controlled based on the prediction. The illumination on the hood may be adjusted, and/or the heating level on the cooktop may be changed, or the entire cooktop may be shut off, based on predictions such as changing the fan level of the hood.
By predicting the environmental conditions based on the detectable values according to the invention, the events to be predicted can be reacted on time. Here, no user interaction is required to react to an event. Dangerous situations, such as overcooking of food, can thus be prevented and a reliable way of functioning of the extractor hood is ensured.
According to a preferred embodiment, the at least one decision criterion comprises a movement in the region of the at least one household appliance and/or at least one control instruction of the at least one household appliance.
The movement of an object in the region of the household appliance, for example on or in the vicinity of the hob, can be detected in a simple manner by means of a camera. Motion has been detected in part on the range hood for identifying a gesture and for controlling at least one household appliance based on the gesture. The use of movement in the region of the domestic appliance as a decision criterion therefore has the advantage that a given detection unit, for example a camera, can be used. The control command of the at least one household appliance (which can be used as a decision criterion) can be, for example, the power level set on the range hood, the activation of the lighting device and/or the temporally recent or current activation of the cooking zone of the hob. The control command is usually present in the control unit of the household appliance and can therefore be used in a simple manner for the method according to the invention.
The movement in the area of the at least one domestic appliance may comprise movement of a pot cover, movement of a user's hand in the area of the cooktop, movement of a user's head in the area of the cooktop, movement of a cooker and/or movement of food.
By using the movement of the pot cover as a criterion, it can be achieved during the evaluation that, on the one hand, the user is in the vicinity of the hob. On the other hand, it is possible to see the user inwardly into the interior of the cooking vessel, and finally, on movement of the pot cover, to increase the steam and smoke in the cooking vessel, which results in a higher smoke quantity on the range hood arranged above the cooking hob, which can be used as a predictable environmental condition of the range hood in the method according to the invention.
The movement of the user's hand in the region of the hob can also be used as a decision criterion, since a movement in the direction of the cooking vessel can anticipate a planned increase of the cooking lid.
Likewise, the movement of the user's head in the region of the hob can be used as a decision criterion, since this movement confirms that the user looks into the cooking vessel when it is directed towards the cooking vessel and lifts the lid with it still on the cooking vessel.
In addition, the movement of the food may also be used as a decision criterion. If there is no movement of the food or only little movement of the food, and in particular movement of the surface of the food, then little temperature of the food can be inferred as an evaluation result. Conversely, if a strong movement of the food and especially of the surface is detected, this indicates a higher food temperature as an evaluation result. The movement of the food may be movement in the surface of the food. Thus, for example, boiling of the liquid food can be detected. Alternatively or additionally, an upward or downward movement of the surface of the food, i.e. an increase or decrease in the surface, can also be detected as a criterion, and from this a temperature increase or cooling of the food can be deduced.
Additionally or alternatively to the movement in the region of one of the household appliances, the control command can also be used as a decision criterion and thus be taken into account when predicting the environmental conditions. The control instructions of the at least one domestic appliance may for example comprise activating a hob, distributing a cooking recipe onto the hob and/or illuminating the hob. The activation hob may be a current activation or an activation performed in advance in time. In this case, it is particularly preferred that the activation of the individual cooking zones is used as a decision criterion. In this embodiment, the assignment of the respective cooking zone to the cooking vessel is preferably performed using additional decision criteria, such as movement. The prediction of environmental conditions can be further improved. If the auxiliary functions of the cooktop are used (in which recipes are stored), the allocation of cooking recipes to the cooktop can be used as a decision criterion. If, for example, food should be cooked in a recipe step, but the lid is identified as lifted as a further decision criterion, then the heat input to the food deficiency may be identified as an environmental condition. The user may then be required to close the lid or heat input may be made by increasing the power level of the cooking zone.
If selective illumination of the cooktop is used as a decision criterion, then for example, the environmental conditions can be predicted so that the user approaches the cooking vessel in the selectively illuminated area.
According to the invention, the predicted environmental conditions of the at least one household appliance may comprise a higher smoke quantity on the range hood, overcooking of the food on the hob and/or deviation from the conditions of the food required for the recipe step.
For example, if a higher temperature of the food is obtained as an evaluation result based on the movement of the surface of the food, it can be predicted as an environmental condition that the smoke amount on the hood increases. Alternatively or additionally, in particular in case the surface of the food is raised, overcooking of the food on the hob may be predicted as an environmental condition.
If an auxiliary function is used (in which the recipe is stored), the environmental condition to be predicted may also be a deviation from the conditions of the food that are required for the recipe step. If, for example, cooking food is required for the recipe step, but it is recognized as a decision criterion that the lid is lifted, the environmental conditions to be predicted are different from the desired conditions for the recipe step.
The predictive controlled based function of the at least one household appliance may include power level adjustment of the range hood, power level adjustment of the cooking zone, deactivation of the cooktop, and/or outputting information to the user.
The information output may be performed by a cooktop, range hood or control device.
For example, if a higher smoke volume is predicted as an environmental condition, then the power level adjustment of the range hood may be increased according to the present invention, i.e., the range hood operates at a higher level. Alternatively or additionally, the cooking zone associated with the cooking vessel may be downshifted, i.e. the power level for at least the cooking zone is reduced. It is also possible to deactivate the entire cooking zone at least temporarily.
Conversely, if, for example, overcooking of food is predicted as an environmental condition, the cooking zone associated with the cooking vessel may be downshifted, i.e. the power level for at least that cooking zone is reduced. It is also possible to deactivate the entire cooking zone at least temporarily. Additionally or alternatively, a warning may also be output to the user by the range hood or cooktop.
If a deviation from the conditions of the food required for the recipe step is predicted as an environmental condition, for example, the cooking zone associated with the cooking vessel can be upshifted, i.e. the power level for at least this cooking zone is increased. Additionally or alternatively, the user of the hob may be informed, for example, of a message or report that he should close the cooking vessel.
According to another embodiment, a reliability check is performed in addition to the prediction. The reliability check can be performed by means of a sensor. In particular, when a higher smoke quantity is predicted and the range hood is correspondingly controlled to a higher power level, it can be checked by means of a sensor on the range hood whether a higher smoke quantity actually occurs. Here, as the sensor, for example, an air quality sensor, a VOC sensor (volatile organic compound sensor), a PM2.5 sensor, a humidity sensor, or a temperature sensor may be used. If the sensor recognizes that the characteristics of the air flowing through the range hood have not changed, the power level of the range hood is reset.
Accordingly, even when overcooking of food is predicted, a corresponding reliability check can occur. If, after the power level of the cooking zone is reduced, for example, it is recognized that no overcooking, as opposed to the predicted environmental conditions of overcooking of the food, has occurred, the power level of the cooking zone may be increased again.
According to another aspect, the invention relates to a control device for operating at least one function of at least one household appliance. The control device is characterized in that the control device comprises at least one detection unit for detecting at least one decision criterion, an evaluation unit for evaluating the detected at least one decision criterion, a prediction unit for predicting at least one environmental condition of the at least one household appliance, and a control unit for controlling at least one function of the at least one household appliance based on the predicted environmental condition.
The advantages and features described in relation to the method according to the invention apply correspondingly to the control device according to the invention and vice versa, as applicable in general.
The method according to the invention is preferably performed with the control device according to the invention.
The control device comprises at least one detection unit, an evaluation unit, a prediction unit and a control unit.
The control device, which may also be referred to as a module, may be integrated in the household appliance. The control device may be integrated in a range hood, for example. In this case, preferably, a range hood is connected to the hob for exchanging data, the range hood being arranged above the hob. The connection may be a wired or wireless connection.
Alternatively, it is also possible for the control device to be a module which is arranged separately from the at least one domestic appliance and is connected to the at least one domestic appliance by a wireless communication connection. In this case, the communication between the control device and the range hood can take place, for example, directly, and the range hood is connected to the hob for communication. Alternatively, however, it is also possible for the control device to be connected to the hob for communication and for the hob to be connected to the range hood for communication. Finally, within the scope of the invention, the control device is connected not only to the extractor hood, but also to the hob. The connection of the control device to the hob and/or the range hood may be a wired connection or a wireless connection.
According to an embodiment, the detection unit comprises at least one camera, a control and monitoring device and/or at least one sensor. Preferably, the camera is a depth map camera. Additionally, the camera may also be designed to capture video. The sensor may comprise, for example, a microphone array. The control and monitoring means of the detection unit are preferably monitoring units which monitor control commands from the control of the hood and/or the hob. The set power level of the range hood or the hob or the cooking area of the hob can thus be detected, for example.
The units of the control device may be at least partly implemented as programs. Furthermore, the units of the control device may be at least partially combined. Furthermore, the unit of the control device may be formed at least in part by a unit of one of the household appliances. At least one component of the detection unit or the control unit may be formed, for example, by a unit on a hob or a range hood.

Detailed Description
An embodiment of a control device 1 according to the invention is shown in fig. 1. In the embodiment shown, the control device 1 is arranged on a range hood 2, which is arranged above a cooking hob 3. The control device 1 is designed and arranged in such a way that the actual situation in the area of the hob 3 can be detected. The area in which the actual situation can be detected is indicated with 10 in fig. 1. In particular, objects and their movements can be detected in the detection region 10.
A schematic block diagram of the elements of an embodiment of the control device 1 according to the invention is shown in fig. 2.
The control device 1 comprises a detection unit 100, an evaluation unit 101, a prediction unit 102 and a control unit 103.
An embodiment of the method according to the invention is schematically shown in fig. 3.
In the method according to the invention, the decision criterion is detected by the control device 1 and in particular by the detection unit 100. As examples for the decision criteria, the activation of the cooking zone, lifting of the pot lid, movement of the hand or head, movement of the food, selective illumination and recipe steps are shown in fig. 3.
If it is detected by the detection unit that the lid of the cooking vessel is lifted, the amount of smoke to be expected may be determined in the prediction unit. Additionally, the movement of the food can also be considered for predicting the amount of smoke. The power level of the extractor hood (which may also be referred to as the fan level) is adjusted by the control unit of the control device to a power level that matches the amount of smoke. Reliability queries may be made after adjusting the power level. The control device can be connected to a sensor of the range hood. It can be known, for example, by means of the value of an air quality sensor on the control unit, whether a change in the air composition takes place, i.e. whether a predicted higher smoke quantity takes place. If this is not the case, the control device may in turn reduce the power level of the range hood.
Additionally or alternatively to determining the amount of smoke to be expected with respect to considering the movement of the surface of the food, the decision criterion may also be used by the control device alone. In particular, when the surface of the food is determined to be raised when evaluating the decision criteria, the point in time of overcooking can be known in the prediction unit. This may be achieved by insertion. If overcooking is expected in the near future, the cooking zone may be switched off, or its power level reduced, by a control unit controlling the device. Although not shown in fig. 3, a reliability query may also be performed in this method. It can be known here, for example, by means of a detection unit of the control device, whether the surface of the food is lowered again. If this is the case, the power level of the cooking zone can be increased again.
With the present invention, it is possible to infer the occurring process from the information detected by the detection unit (i.e. the decision criterion) and to introduce the necessary measures. Different processes can be detected here.
On the one hand, food, such as pan/pan content, may be detected. The cooking pot or pan can be detected by means of a detection unit (which for example comprises a camera) and optionally by means of a depth map detected by the detection unit by means of an object recognition algorithm. The cooking zone of the hob associated with the object thus detected (cooking pot/pan) and the associated power controller can be identified by the detection unit or the unit connected thereto on the hob. Here, the operation of the cooking zone or the operation that has recently ended may be considered as a decision criterion. If accurate detection of the contents of a pan or pan is possible, the liquid/food surface is considered as an additional criterion. The liquid/food surface may be evaluated in the evaluation unit in the following manner. If no or only little surface movement is detected, a cold food product is obtained. Conversely, if a strong surface movement or elevation of the liquid level of the food is detected, a hot food is obtained. If the range hood also has an additional sensor unit (e.g. a gas sensor for air quality/VOC, PM2.5, humidity, temperature, etc.), its signal change can likewise be considered as an additional decision criterion. Alternatively, the signal change can also be used as a reliability query after controlling the range hood. By means of the method according to the invention, in a system consisting of an extractor and a hob, the cooking process (e.g. boiling of water or bubbling of milk) is identified to react in different ways:
-reducing cooking zone power
Cutting off cooking areas or cooktops
Informing the software interface connected to the control device of the situation, such as a smartphone/tablet
-informing the condition directly on the hood or hob, for example by means of a warning signal.
Nowadays, additional systems, such as sensors, which are arranged on the pan or pan, are required for detecting the cooking temperature, which only work with a specific pan and pan. Thus detecting and regulating the exact temperature by the heating circuit. In devices which operate by means of detection of thermal radiation in the IR range, however, the application can only be realized with a surface suitable for this purpose, or special measuring marks have to be provided. IR measurements may however fluctuate in their accuracy. An additional system is a temperature recognition system by means of IR detection for the baking process on the bottom of the pan. The temperature identification system is however inaccurate and is not suitable for accurate adjustment of the cooking process.
In the intelligent connection according to the invention of process detection, in particular optical process detection, carried out by the control device during cooking, advanced system reactions can be carried out before or simultaneously with a cooking event. In the present invention, the system reaction may be, for example, cutting off the cooking zone. Overcooking of food, such as milk, can thus be expected and thus prevented.
According to another embodiment, the subsequent process may be used, for example, as a decision criterion. On the one hand, the removal of the pot cover (which removal can be detected, for example, by means of a camera and optionally by means of a depth map and by means of an object recognition algorithm) can be used as a decision criterion. Furthermore, the operation of the hob for the predicted smoke quantity or the operation that has recently ended can be considered as an optional further decision criterion. If a clean assessment of the pan or pan contents should be possible, the liquid/food surface is considered as an additional decision criterion. The liquid/food surface may be evaluated in the evaluation unit in the following manner. If no or only little surface movement is detected, a cold food product is obtained. Conversely, if a strong surface movement or elevation of the liquid level of the food is detected, a hot food is obtained.
Additionally, it may be monitored whether the hand/cloth is near the lid of the pot or otherwise lifting the lid after authentication of the lid. Furthermore, it is obtained that the user will look at the pan when removing the lid. The pan is selectively illuminated, which can be considered as an additional decision criterion. In cooking according to recipes known for auxiliary functions, the user may be required to close the lid acoustically or optically according to the current recipe section. If a plurality of criteria are evaluated positively in the evaluation unit, i.e. a higher smoke volume is expected to reach the range hood shortly thereafter, the fan level of the range hood can be adjusted accordingly. If, however, a misprediction should be made, a reliability query is optionally made with the aid of sensors (e.g., air quality/VOC, PM2.5, humidity, temperature, etc.). If the properties of the air-smoke mixture are not changed, the reset power increases after a short increase.
Unlike systems that can only utilize the time lag from an initial event to trigger the presence of a system reaction, the intelligent connection according to the present invention of the detection unit, especially the optical process detection during cooking, can be utilized to achieve a leading system reaction prior to or concurrent with a cooking event.
Preferably, the hob and its operating panel are located entirely in the area detected by the control device, which may also be called a module, and in particular a PAI module (projection and interaction module). In this case, a depth map and a video image are preferably present throughout the cooking process. The position of the operator can also be determined additionally by means of a microphone array.
As mentioned above, the control device may be designed in a range hood or as a separate appliance. In the last case, the control device is arranged above the work plate and preferably the hob in a similar height as the extractor hood. The object and/or gesture can be recognized by the control unit. Preferably, the user interacts with the range hood through gestures. The operation of the cooktops and other networked appliances can be performed by means of an operating panel, which is located in the detection area of the control device.
With the invention, the action intention of the user and the flow of the cooking process can be interpreted and sometimes predicted by means of machine object recognition, and meaningful measures are introduced. When it is recognized that the lid of the cooking pot or pan is opened, the fan level of the extractor hood may be matched to the expected amount of smoke, for example, before the elevated smoke physically reaches the extractor. Additional recognition algorithms may, for example, recognize the liquid state: cold = no/little surface movement and heat = strong surface movement or elevation of liquid level. In this way, for example, the overcooking of the liquid can be calculated in advance and an automatic advance switching off or a reduction of the hob power can be initiated by transmitting data to the hob.
Another advantage of the present invention is that with very little smoke generation, the range hood operates at a low power level and thus reduces noise formation. If in the current system a higher amount of smoke occurs during cooking, i.e. smoke flooding (wrasenchwall), the smoke flooding is not sufficient to be inhaled through the extractor based on a small fan level. Most of the smoke flows into the kitchen air. By the intelligent smoke prediction enabled in the present invention, short term formed smoke floods (lifting of the pot cover) can be balanced so that almost all smoke can be captured by the range hood without having to run the range hood continuously at high power levels.
