Description

The invention relates to a method for detecting operating parameters of a treatment room of a household appliance, in which a self-sufficient sensor is arranged on the household appliance, during an operating sequence of the household appliance by means of the self-sufficient sensor at least one operating parameter of the treatment room is measured and generated by the sensor measurement data are sent wirelessly , The invention also relates to a system that is set up to carry out the method. The invention further relates to a method for creating a menu sequence. The invention is particularly advantageously applicable to methods for detecting operating parameters of a cooking chamber of a cooking appliance.

A domestic appliance is known in which at least one sensor and a communication module are integrated and which is set up to transmit data of the household appliance, including measurement data generated by the at least one integrated sensor, to a device-external instance via the communication module. The data transmitted to the device external entity may be used to link an operation of the household appliance with the operation of other such household appliances, for example, to allow a user a proposal for a concerted operation of several household appliances. However, many household appliances today still have no communication module, so that their connection to other household appliances is not possible.

It is the object of the present invention to overcome the disadvantages of the prior art, at least in part, and in particular to provide a way to tune also an operation of not equipped with communication modules home appliances to operate with other household appliances.

This object is achieved according to the features of the independent claims. Advantageous embodiments are the subject of the dependent claims, the description and the drawings.

• - ein autarker Sensor an dem Haushaltsgerät angeordnet wird,
• - während eines Betriebsablaufs des Haushaltsgeräts mittels des autarken Sensors mindestens ein Betriebsparameter des Behandlungsraums gemessen wird und von dem autarken Sensor erzeugte Messdaten drahtlos an eine geräteexterne Instanz gesandt werden,
• - die Messdaten über die geräteexterne Instanz an eine geräteexterne Datenbank übertragen und dort als Referenzdaten gespeichert werden und
• - zusätzlich zu dem Betriebsablauf zugehörige Betriebseinstellungen an die Datenbank gesandt und dort verknüpft mit den Messdaten gespeichert werden.

The object is achieved by a method for detecting operating parameters or operating parameter values of a treatment chamber of a domestic appliance, in which

• an autonomous sensor is arranged on the household appliance,
• during an operating sequence of the domestic appliance, at least one operating parameter of the treatment room is measured by means of the self-sufficient sensor, and measurement data generated by the autonomous sensor are sent wirelessly to an external device,
• - transmit the measured data via the external device to an external database and store it there as reference data, and
• - In addition to the operation associated operation settings sent to the database and stored there linked to the measurement data.

This method provides the advantage that a course or temporal behavior of the at least one operating parameter of the treatment room in the database as a reference for the following operations under the same operating settings can be stored and for an operational planning with other loads also available or available when the home appliance itself can not communicate with the database and thus can not deliver even real-time data of the operating parameters to a device external instance. In turn, an operational plan for future operations may include high accuracy home appliances that are designed as non-networkable devices due to their age or equipment.

Thus, the method does not serve treating treated material, but for receiving a reference measurement. The method may thus also be referred to as a method for acquiring reference operating parameters, and the operating procedure may be referred to as a reference operating procedure. In particular, the method does not serve for the regulation of operating parameters during an operating procedure and can thus also be regarded or referred to as a regulation-free method.

The fact that the database is an external database means that the database is not integrated into the household appliance or the sensor. Such a database may be, for example, in a user terminal (eg a smartphone, a tablet PC, a laptop, a desktop, a so-called "wearable" such as a SmartWatch, etc.) on a network server (eg a server of the manufacturer of the household appliance) and / or in a computer network such as the so-called "cloud". The database can be integrated into the device-external instance to which the sensor transmits its measurement data. Thus, the device external instance may be a smartphone that has the database. In an additional or alternative development, the device-external database is present in a further device-external instance (for example, a network server of the manufacturer of the household appliance), the measurement data then being transmitted by the device-external instance, which receives the measurement data sent by the sensor, are forwarded to the database.

A self-sufficient sensor is understood to be a sensor which is operable independently of the household appliance and can be removed from the household appliance. In particular, this sensor is used only for measuring reference measurement data and not for measuring operating parameters during treatment of a material to be treated. Such a sensor has in particular at least one sensor element for measuring the at least one operating parameter and a communication unit and a power supply for supplying the sensor with electrical energy. The power supply may include a battery or a rechargeable battery. The sensor can also have at least one data processing device for processing the sensor signals generated by the at least one sensor element. The data processing device may transmit the sensor signals e.g. Digitize, format and / or edit content.

• - Temperatur,
• - Feuchtigkeit,
• - chemische Konzentration

umfasst.It is a development that the at least one operating parameter has at least one parameter from the group:

• - temperature,
• - Humidity,
• - chemical concentration

includes.

The sensor is a wirelessly communicating sensor, i.e., its communication unit is designed or set up for wireless communication. The communication unit may be a radio-based communication unit, e.g. Transmits data according to the Bluetooth standard, the WLAN standard, etc. The communication unit may transmit measurement data and possibly other data (for example via an operating state of the sensor) and may optionally also be configured to receive data (for example control commands).

It is a development that the sensor has a cable as an antenna. This results in the advantage that the cable is in an arrangement of the sensor in a treatment room of the household appliance through a door gap between a door closing the treatment room and a housing of the household appliance can be guided to the outside. This in turn improves a data transmission from the sensor to a device-external instance receiving the measurement data of the sensor.

It is a development that the sensor has at least one operating element. This simplifies the implementation of the method for a user. It is a further development that the operating element is set up to record and send measured data by actuating the operating element. This can also be referred to as activating the sensor. The sensor may be configured to terminate acquisition and transmission of the measurement data (which may also be referred to as deactivating the sensor) when a predetermined amount of time has been reached or exceeded, when a critical operating condition of the sensor has been reached, or in the near future is achieved and / or when the actuator is activated again when the sensor is activated. It is also a further development that the operating element is set up to switch the sensor on by actuation or switch it off, without measuring values being transmitted by switching on. The transmission of the measured values can be initiated remotely, in particular in this case, for example, at the direction of a user terminal equipped with an application for carrying out the method. In particular for this case, a communication unit of the sensor can be set up both for transmitting and for receiving data. Also, the termination of the recording and generation of measurement data can be done remotely. The sensor can thus be designed in a variant generally as a remotely controllable sensor.

It is a further development that the sensor has a display device (for example a small lamp) which lights up in the activated state of the sensor. The sensor can also have a display device which indicates a critical operating state of the sensor. The display device for displaying the critical operating state may correspond to the display device for displaying the activated state.

For example, the display device in the switched on, non-critical operating state permanently lit, flashing with reaching a critical operating state.

It is a further development that the sensor is set up to transmit the measured data to the device-external instance by means of a point-to-point (P2P) connection or by integration into a home network. This can be implemented in such a way that the sensor is logically connected to a corresponding device or remote station before it is activated or used. For example, the sensor can be coupled via a so-called "pairing" with a user terminal such as a smartphone or a network access point (such as a router, eg a WLAN router) and then sends its measurement data automatically to the User terminal or the network access point. The user terminal or the network access point can then be used to forward the measurement data to the user database. If the database is integrated in the user terminal, the measurement data can be stored by the user terminal directly in the user database. The sensor can thus be configured in a development as a network-capable sensor. For this purpose, the sensor can be assigned a network address in a development.

The operational settings stored for the reference operation may be entered by a user, for example via an application program e.g. a user terminal, by means of which the user can perform the method. The operating settings stored in the database are also reference settings. By linking the operating settings with the measured data, these can be stored and read in a simple manner as a data record in the database.

In one possible sequence of the method, a user opens an application program ("app") provided for the course of the procedure at his user terminal and switches on a remotely controllable self-sufficient sensor. In the following, a data connection between the sensor and the user terminal is automatically established, since the sensor and the user terminal have previously performed a pairing procedure (for example, when setting up the sensor for the first time). Subsequently, the user arranges the sensor to the treatment room and turns on the household appliance with desired operating settings. The user also enters these operating settings via the application program on the user terminal. In this case, the order of whether the user first inputs the operating settings to the user terminal and then only makes the operating settings on the household appliance, or vice versa, irrelevant. Subsequently, the user activates the reference measurement procedure via the application program, whereupon the user device instructs the sensor to dissipate operating parameters via its at least one sensor unit and to wirelessly transmit corresponding measurement data to the user terminal. The measurement data, linked to the entered operational settings, are transmitted by the user terminal to the database where they are stored. The measurement data stored in the database can be used below as reference data for operation of the household appliance with the user-set operating settings. The measuring process can be ended automatically after a predetermined period of time or via the application program by a user interaction. It is particularly advantageous if the measured data of a measuring procedure transmitted to the user terminal are first of all completely stored in the user terminal and then first transferred to the database together with the operating settings. A user can perform the procedure for several different operations (for example, by varying the selected operating settings).

It is an embodiment that the operation settings include manually set operation settings such as an operation mode, a target temperature, a target state of the material to be treated, and so on.

It is an embodiment that the operating settings include a type of cooking program (e.g., steaming vegetables, roasting fish or meat, etc., especially with automatically varied operating parameters). Thus, the advantage is achieved that even a program function of household appliances can be included in an operational plan.

It is also possible that the operating settings include a combination of a selected type of operating program with manually set operating settings.

It is an embodiment that the method is performed with empty treatment room. Thus, loading independent measurement data can be stored as a reference in the database.

It is an embodiment that a treatment chamber of the household appliance is or will be charged before the start of the operation with reference material to be treated. This results in the further advantage that measurement data of a more realistic operating procedure can be recorded and fed into a planning process. Such reference treatment type can be given to a user or individually specified by a user. The reference type of treatment may be, for example, water of a certain volume. It is a further development that then additionally the material to be treated (for example characterized by its type, its weight, etc.) linked to the measured values can be stored in the database.

It is an embodiment that the sensor is arranged in the treatment chamber of the household appliance. This allows a particularly accurate measurement of operating parameters within the treatment room. In addition, so particularly inexpensive sensor elements such as thermocouples, etc. can be used.

It is one in the event that a treatment room of the household appliance before the beginning of Operation is loaded with reference material to be treated or has been and that the sensor is placed in the treatment room of the household appliance, further embodiment that the sensor has a ("reference") recording or a filling container for the reference material. This results in the advantage that a temperature change of the reference material to be treated can be particularly precisely sensed so that particularly realistic measurement data can be recorded and fed into a planning process. In addition, so advantageously direct measurements of the contents of the recording can always be made with the same wall thicknesses and the same volume, etc., which increases the reproducibility of the measurements. The receptacle is therefore intended in particular for filling with a predetermined amount of liquid, for example water. On or in the receptacle, a sensor element, for example a temperature sensor element, may be present. The sensor may comprise at least one further sensor element for sensing a property of an atmosphere of the treatment space, for example a temperature sensor element or a moisture sensor element. Such a sensor also solves the task independently.

It is an embodiment that the sensor is arranged outside the treatment chamber of the household appliance. This advantageously enables a stress of the sensor to be kept low or even completely avoided by conditions prevailing in the treatment space, such as a high temperature and / or humidity or mechanical stresses. Such a sensor may in particular have a non-contact sensing sensor element such as an IR sensor. The IR sensor may be formed, for example, as a thermopile, etc. In one type of application, the sensor may be attached to a door opening the treatment room, in particular to a viewing window of the door, if present. The attachment may e.g. be implemented by at least one suction cup, hooks, etc.

• - der Sensor an einem Speisenbehandlungsraum des Speisenbehandlungsgeräts angeordnet wird und
• - während eines Betriebsablaufs des Speisenbehandlungsgeräts zumindest Temperaturmessdaten von dem Sensor ausgesandt werden und als Betriebseinstellungen zumindest (a) eine zu dem Betriebsablauf zugehörige Speisenbehandlungsbetriebsart und mindestens ein eingestellter Sollbehandlungsparameter und/oder (b) ein eingestelltes Speisenbehandlungsprogramm (ggf. mit mindestens einem zugehörigen Sollbehandlungsparameter) in der Datenbank gespeichert werden.

It is an embodiment that the household appliance is a food treatment device and in the process

• - The sensor is placed on a food treatment room of the food processing device and
• at least temperature measurement data from the sensor are emitted during operation of the food processing device and at least (a) a meal treatment mode associated with the operation and at least one adjusted desired treatment parameter and / or (b) a set meal treatment program (optionally with at least one associated desired treatment parameter) stored in the database.

Thus, when treating foods, it is advantageously possible to record typical operating settings as a reference and retrieve them later. Target treatment parameters may include, for example, a period of time (timer time), a set temperature, a target heating power such as a microwave power, a heating level, and so forth.

• - eine Backofenfunktionalität,
• - eine Dampfbehandlungsfunktionalität,
• - eine Mikrowellenfunktionalität.

It is a development that the food processing device has at least one of the following functionalities:

• - an oven functionality,
• a steam treatment functionality,
• - a microwave functionality.

The food handling device may also be a fryer.

• - das Speisenbehandlungsgerät einen Backofen aufweist (z.B. falls das Speisenbehandlungsgerät ein Herd oder ein eigenständiger Backofen ist), der Speisenbehandlungsraum ein Garraum des Backofens ist und die Speisenbehandlungsbetriebsart eine Backofenbetriebsart ist und bei dem
• - eine zu dem Betriebsablauf zugehörige Speisenbehandlungsbetriebsart in Form einer Backofenbetriebsart und ein mindestens eingestellter Sollgarparameter in Form zumindest einer Solltemperatur und/oder ein eingestelltes Garprogramm in der Datenbank gespeichert werden.

It is an embodiment that

• the food treating appliance has an oven (eg if the food treating appliance is a stove or an independent oven), the food treatment room is a cooking space of the oven and the food treatment mode is an oven mode and in which
• - An associated with the operation food handling mode in the form of an oven mode and an at least set Sollgarparameter be stored in the form of at least one set temperature and / or a set cooking program in the database.

The oven mode may include typical oven modes such as a bottom heat mode, a top heat mode, a combined bottom and top heat mode, a hot air mode, a grill mode, a recirculation mode, etc., with optional features such as steam cooking mode, microwave mode, etc.

It is a further development that moisture measurement data and / or concentration measurement data of predefined chemical substances detected by the sensor during an operating sequence of the food processing device are transmitted from the sensor to the database. The chemicals may be substances during a baking process or other food treatment process, the occurrence of which characterizes a particular condition of treatment of a food. Such substances may, for example, during boiling and / or tanning material emitted or exiting a food. A sensor unit integrated into the sensor for detecting the chemical substances can then be, for example, a tanning sensor.

However, the method is not limited to food handling equipment, but can also be used for other household appliances, for example for laundry care appliances, refrigerators, dishwashers, etc.

It is an embodiment that, based on the measured data measured by the sensor, further sensor data belonging to the operating sequence are extrapolated. This provides the advantage that the time taken by the sensor to record the measurement data can be shortened. Also, there is the advantage that the sensor only needs to be used in operating parameter areas which preclude damage to the sensor in the treatment room. In addition, energy can advantageously be saved in this way. The extrapolated sensor data describe a further course of the measured operating parameters at least approximately. For example, upon reaching a predetermined critical threshold value of at least one operating parameter (for example, a critical temperature threshold value), the sensor issues an indication to a user that the measurement procedure should now be ended and the household appliance should be switched off. Alternatively or additionally, the sensor can be remotely instructed upon reaching the threshold to terminate the measurement process and / or turn off. The extrapolation can be carried out in particular by means of a device-external instance, for example by means of a comparison with characteristic curves and / or by a formulaic calculation. The device-external instance can be a user terminal equipped with an application program for carrying out the method. The extrapolated sensor data are stored together with the measured sensor data in the database.

The method described above can also be carried out using a plurality of, in particular different, self-sufficient sensors, which are arranged on the same treatment space. In this case, the measured data of all these sensors are advantageously stored together in the database. The operating settings need only be entered once by a user for the measurement data of the multiple sensors.

The object is also achieved by a system comprising at least one self-sufficient sensor and a database for carrying out the method as described above. The system may be analogous to the method and provides the same advantages.

• - Eingaben eines Nutzers zu Speisen einer Menüfolge und von zur Zubereitung der jeweiligen Speisen zu verwendenden Speisenbehandlungsgeräten mit gewünschten Betriebseinstellungen aufzunehmen,
• - zu überprüfen, ob in der nach dem oben beschriebenen Verfahren befüllten Datenbank Messdaten zu mindestens einem Speisenbehandlungsgerät mit den gewünschten Betriebseinstellungen vorhanden sind,
• - falls ja, beruhend auf den zugehörigen Messdaten Handlungsanweisungen zum Betrieb des mindestens einen Speisenbehandlungsgeräts zusammen mit anderen zu der Menüfolge gehörigen Handlungsanweisungen in zeitlicher Abfolge einem Nutzer bereitzustellen.

It is an embodiment that the system further has a user interface that can be coupled to the database in terms of data technology and that is set up to

• To record inputs of a user for feeding a menu sequence and food handling devices to be used for preparing the respective food with desired operating settings,
• to check whether, in the database filled according to the method described above, measurement data are available for at least one food processing device with the desired operating settings,
• if so, based on the associated measurement data, instructions for the operation of the at least one food processing device together with other instructions relating to the menu sequence can be provided to a user in chronological sequence.

This can also be called "Guided Cooking". The user interface can be, for example, a user terminal equipped with a corresponding application for carrying out the method.

In one possible application example, an operation of the plurality of household appliances can be timed to one another in such a way that a user can create a desired and predetermined menu or sequence of dishes by him particularly easily and in a short time. For example, the measurement data (such as a temperature history and / or a moisture history in the meal processing room for a desired operation) determined by a food treatment mode by means of the self-sufficient sensor can be automatically used to estimate a probable time period for food treatment. This estimated period of time can be integrated into a user's work instruction to create the menu. If the food processing device is, for example, an oven, a time period until the completion of a food to be cooked can be estimated with high accuracy by the measured temperature profile. Knowing this period of time, a user can be given an indication of when he should have completed other foods of the selected menu in order to serve a particular course of the menu with freshly prepared foods.

• - Eingaben eines Nutzers zu Speisen einer Menüfolge und von zur Zubereitung der jeweiligen Speisen zu verwendenden Speisenbehandlungsgeräten mit gewünschten Betriebseinstellungen aufgenommen werden,
• - überprüfen wird, ob in der nach dem oben beschriebenen Verfahren befüllten Datenbank Messdaten zu mindestens einem Speisenbehandlungsgerät mit den gewünschten Betriebseinstellungen vorhanden sind,
• - falls ja, beruhend auf den zugehörigen Messdaten Handlungsanweisungen zum Betrieb des mindestens einen Speisenbehandlungsgeräts zusammen mit anderen zu der Menüfolge gehörigen Handlungsanweisungen in zeitlicher Abfolge einem Nutzer bereitgestellt werden.

The object is further achieved by a method for creating a menu sequence in which

• - Inputs of a user to feed a menu sequence and to be used for preparing the respective food to be used food processing equipment with desired operating settings,
• check whether there is measurement data for at least one food processing device with the desired operating settings in the database filled in according to the method described above,
• if so, based on the associated measurement data, instructions for the operation of the at least one food processing device together with other instructions relating to the menu sequence are provided to a user in chronological sequence.

The method can be configured analogously to the method and / or system described above and has the same advantages.

The method can generally be used for any combination of household appliances, for example for operational planning, taking into account cooking appliances, refrigeration appliances and / or dishwashers.

• - A sensor element in the form of a temperature sensor 3 for measuring a temperature,
• - a communication unit 4 (eg a Bluetooth or a WLAN module) for the wireless transmission of data with an external device G .
• - one with the temperature sensor 3 and the communication unit 4 connected or coupled data processing device 5 for processing sensor signals of the temperature sensor 3 to measurement data and to transmit the measurement data to the communication unit 4 and for receiving control commands by the communication unit 4 and controlling the sensor 1 based on received control commands,
• - A power supply in the form of a battery 6 etc. to supply the sensor 1 with electrical energy and
• - a button 7 for switching the sensor on and off 1 on.

on.

The sensor 1 can be an example in a cooking chamber R an oven B be inserted. The from the sensor 1 through the communication unit 4 Sent and received data can thereby penetrate a viewing window of a door (not shown). The door is thus transparent to the frequency band used for data transmission.

The device-external instance G may be a user terminal such as a smartphone, a tablet PC, a laptop, a desktop, a wearable, etc. In particular, a switched-on sensor can 1 automatically with the device-external instance G data-technically coupling, for example, by a first commissioning of the sensor 1 a so-called "pairing" process has been performed with the user terminal. From the sensor 1 transmitted data are thus from the device external instance G received and can be stored there, cached and / or to another device external instance G2 to get redirected. The further device-external instance G2 may be, for example, a network server or the so-called "cloud". The device-external instance G may be equipped or provided with an application program A, which is set up to carry out the method described above.

Database 2 can be in the device external instance G and / or - as shown - in the further device external instance G2 to be available. The connection of the device-external instance G with the further device external instance G2 can also be produced or provided by means of the application program A.

2 shows a possible sequence of a method for detecting a cooking chamber temperature of the cooking chamber R of the oven B , It is assumed that the sensor 1 and the device-external instance G have previously undergone a "pairing" process, the automatic data technology coupling of the sensor 1 with the device-external instance G when the sensor is switched on 1 allowed.

To carry out the method, a user can in a first step S1 the sensor 1 by pressing the button 7 turn on. This will be the sensor 1 automatically with the device-external instance G coupled, especially if on this the application program A is open or activated to perform the method.

In a second step S2 gives the user via the application program A Operating settings of the oven B a, for example, an oven mode such as a hot air mode, etc., and a target cooking space temperature.

In a third step S3 the user places the sensor 1 in the oven R one. The cooking space R is in particular - except for the sensor 1 -empty.

In a fourth step S4 the user puts on the oven B those operating settings, which he also included in the application program A entered.

The steps S1 to S4 can be done in any order.

With switching on the oven B the user starts in a fifth step S5 at the application program A a measurement process, for example by pressing a start field. Pressing the start field sends the device-external instance G a control command to the sensor 1 that's about the communication module 4 is received and the data processing device 5 instructs about the temperature sensor 3 Receive sensor signals to convert into measurement data and this measurement data via the communication module 4 send out. The transmitted measurement data are from the device external instance G received and cached there. The measured data show a progression of the cooking chamber temperature for the selected operating settings.

In a sixth step S6 the measurement process is ended, for example on the basis of reaching a predetermined time duration, on the basis of reaching a predetermined temperature threshold value and / or on termination by the user via the application program A.

Upon completion of the measuring process will be in a seventh step S7 the measured data together with the entered operating settings from the device external instance G to the database 2 transferred and stored there linked.

3 shows a possible sequence of a method for creating a menu sequence.

In one step S8 For example, a user uses a user interface (eg, a user terminal, not shown) by opening a program to create a menu sequence and enters a desired menu sequence indicating food to be prepared and household appliances to be used.

In one step S9 As part of this program, the user enters the oven B want to operate with operating settings for which measurement data in the database 2 are deposited.

In one step S10 will check if in the database populated by the above procedure 2 Measurement data for at least one food processing device ( B ) are present with the desired operating settings,

If yes, will be in one step S11 by the program based on the associated measurement data in the database 2 retrieved and used to estimate a duration of a cooking process under these operating settings.

In one step S12 this period of time is used by the program to provide the user with instructions or instructions for the oven B (For example, times to load the oven with a meal and / or to remove the food from the oven), which is the operation of the oven B tunes to other actions or instructions for creating the menu sequence.

Of course, the present invention is not limited to the embodiment shown.
