COOKING SYSTEM WITH AN INDUCTION HEATING BOARD

Description

[0001] The present invention relates to induction cooking appliances, and in particular a cooking system comprising a hob with at least one induction cooking zone and at least one utensil adapted to be heated by the induction cooking zone.

[0002] Document FR3015210A1 describes a cooking utensil comprising a signal processing unit connected to a magnetic field measuring device and a two-way wireless communication module to form a cooking system with a hob by establishing a connection with the latter.

[0003] WO 2010 / 080738 A1 (ACCESS BUSINESS GROUP INT LLC [US]; BAARMAN DAVID W [US] ET AL.) July 15, 2010 (2010-07-15) discloses a cooking system comprising a cooktop including at least one induction cooking zone, a control unit arranged to apply temperature or power instructions to at least one induction cooking zone, and a communication module.

[0004] However, this cooking system can have drawbacks, especially if it includes a cooking control feature. In such cases, it is crucial to implement adequate safety measures for both the user and the equipment to prevent any risk of running dry or in an unsuitable manner.

[0005] The invention makes it possible to remedy these disadvantages and aims first of all to offer a cooking system which guarantees the safety of use of the cooking system composed of a cooking utensil and an induction hob communicating with each other.

[0006] For this purpose, the invention relates to a cooking system as described in claim 1.

[0007] Although the user may have pre-selected a recipe, they will need to confirm this selection once the cookware and induction cooking zone are configured. The second confirmation prompt therefore follows the initial confirmation prompt for the cooking zone configuration.

[0008] According to the implementation described above, the control unit (integrated into the cooktop or cookware) is designed to send cooking instructions to the control unit only under certain conditions, in order to prevent improper or empty use. Specifically, it is necessary to verify that a cooking utensil is properly placed on the induction cooking zone (thus forming a cooking unit or system), and it must also receive confirmation that a recipe step has been selected and confirmed by the user. Only then can the control unit begin cooking autonomously. Such a system ensures that a utensil is indeed in place on the induction cooking zone, receiving cooking instructions, and that a specific action has been confirmed by the user, thereby guaranteeing the safety of both the user and the appliance.

[0009] According to an implementation: The location module, after sending the first information, is arranged to regularly check if the cooking utensil is still placed on the determined induction cooking zone; the control unit is arranged to suspend or stop the application by the control unit of the temperature or power instructions on the determined induction cooking zone if the location module detects that the cooking utensil is no longer placed on the determined induction cooking zone.

[0010] Such repeated checks ensure that the system is always in accordance with the initial configuration and therefore suitable for the action or recipe in progress initially confirmed.

[0011] In one implementation, the cooking utensil includes at least part of the user interface, and the second confirmation signal is received by the control unit if the user selects at least one step of at least one recipe on the cooking utensil's user interface. In other words, if the recipe selection is made locally on the cooking unit—that is, on the cooktop or the cooking utensil—then this constitutes a confirmation.

[0012] According to one implementation, the cooking utensil includes the control unit.

[0013] According to one implementation, the cooking utensil includes at least some of the local storage means.

[0014] According to one implementation, the cooking utensil communication module and / or the cooking hob communication module are capable of communicating with a remote electronic device, itself capable of communicating with remote storage means, all or part of the content of the remote storage means being capable of being sent to the local storage means via the remote electronic device.

[0015] The user can then benefit from the ability to download specific recipes from a remote server (via the internet, for example), and then send them from a mobile phone such as a smartphone, a connected assistant (such as a smart speaker) or a tablet to local storage devices.

[0016] In one embodiment, the user interface includes a screen located on the remote electronic device for the user to select at least one step of at least one cooking recipe, and includes a confirmation means located on the cooktop or cooking utensil to allow the user to generate a second confirmation message for selecting at least one step of at least one cooking recipe from the cooking unit comprising the cooktop and the cooking utensil. In another embodiment, the user interface includes a microphone located on the remote electronic device for the user to select at least one step of at least one cooking recipe.

[0017] In this case, the user selects a recipe on their mobile phone (or tablet) and then confirms this selection using a confirmation method. This confirmation method is therefore local (it is part of the cooktop or cooking utensil), which ensures the user is in the immediate vicinity of the cooktop when confirming.

[0018] According to one implementation, if the control unit has not received the first and second information, then the control unit is arranged to prohibit the transmission to the hob control unit of a series of temperature or power setpoint instructions stored in local storage means and originating from the cooking utensil communication module or the hob communication module.

[0019] In other words, the system locks communication to the control unit until both conditions (formation of the cooking set and confirmation of the recipe) are validated.

[0020] According to one implementation, the cooking unit includes sensors for physical quantities, and the communication module of the cooktop and / or cooking utensil is arranged to provide feedback to the remote electronic device on measurements taken by these sensors on these physical quantities.

[0021] According to the implementation above, the user benefits from feedback on the cooking process, such as temperature, elapsed cooking time, or end of cooking.

[0022] According to one implementation, the cooktop includes a plurality of induction cooking zones, the control unit is arranged to transfer to the cooktop control unit a sequence of excitation of the induction cooking zones of the cooktop until the locating module detects the presence of the cooking utensil and determines on which induction cooking zone the cooking utensil is placed.

[0023] According to the above implementation, the excitation sequence reliably determines which induction cooking zone receives the cooking utensil.

[0024] According to one implementation, the cooking utensil includes a magnetic field measuring device and autonomous power supply means to supply energy to said magnetic field measuring device and the communication module of the cooking utensil, the location module being arranged to receive from the magnetic field measuring device a confirmation signal of the presence or absence of a magnetic field that may be generated by the determined induction cooking zone on which the cooking utensil is placed.

[0025] According to the above implementation, the determination is strengthened, as it involves detection of excitation at the cooking utensil level.

[0026] According to one implementation, the cooktop includes a plurality of induction cooking zones, the location module includes a selection device arranged on the user interface to allow the user to declare the induction cooking zone on which the cooking utensil is placed to form the cooking set and allow the location module to generate the first information.

[0027] According to one implementation, the user interface on which the selection device is located is on the cooking plate or cooking utensil forming the cooking set and the second confirmation information is received by the control unit if the user selects on the user interface at least one step of at least one cooking recipe.

[0028] According to the implementation described above, confirmation is received locally, i.e., either via the cooktop or the cooking utensil. In other words, if the recipe selection is made locally on the cooking utensil or the cooktop, then this constitutes confirmation.

[0029] According to one implementation, after the control unit has received the second confirmation information for at least one step of at least one cooking recipe, the control unit is arranged to transmit to the hob control unit a command to activate an induction cooking zone according to a predetermined temperature or power setting until the control unit receives the first information sent from the locator module confirming that the cooking utensil is placed on the then-determined induction cooking zone, or until the end of a predetermined period after which the locator module has not detected the presence of a cooking utensil on said determined induction cooking zone,In the event of detection of the cooking utensil on the designated induction cooking zone, the control unit is configured to transmit to the control unit a series of temperature or power setpoint instructions stored in local storage devices for the execution of at least one step of at least one cooking recipe.

[0030] The induction cooking zone for the cookware is automatically selected according to the above implementation, once the system receives confirmation of at least one step of at least one recipe. This simplifies the use of the cooking system.

[0031] The invention also relates to a cooking process implemented by the system of the invention, as defined in claim 15.

[0032] The technical features and implementations of the invention described above can be separated from each other and / or combined with each other, as long as there are no technical incompatibilities.

[0033] The attached drawings illustrate non-limiting examples of the invention: There figure 1 represents the main elements of a cooking system according to the invention, namely a cooktop, a cooking utensil, and a remote electronic device; The figure 2 represents an early example of a cooking system of the figure 1 with the cooking utensil placed on an induction cooking zone of the hob, during the initial phase of use; The figure 3 represents the first example of a cooking system of the figure 2 with the cooking utensil placed on an induction cooking zone of the hob, during a second phase of use; The figure 4 represents the first example of a cooking system of the figure 2 with the cooking utensil placed on an induction cooking zone of the hob, during a third phase of use; The figure 5 represents the first example of a cooking system of the figure 2 with the cooking utensil placed on an induction cooking zone of the hob, during a fourth phase of use; The figure 6 represents a second example of a cooking system of the figure 1 with the cooking utensil placed on an induction cooking zone of the hob; The figure 7 represents the steps of a nominal use of the cooking system according to the invention;

[0034] In this application, a cooking zone is defined as an area of ​​the cooktop intended for heating at least one cooking utensil. An induction cooking zone may therefore consist of one or more inductors forming a cooking zone designed to heat a cooking utensil.

[0035] In this application, a cooking step, or a cooking recipe, refers to a series of actions performed on a cooking utensil containing, or intended to contain, food to be prepared. For example, heating water in a saucepan to a boil, then maintaining it at a medium boil for a specified time to cook pasta, and finally turning off the heat at the end of that predetermined time, can be considered a cooking recipe. During this cooking recipe, the induction cooking zone must, in particular, supply a variable amount of heat over time. To this end, the induction cooking zone receives one or more successive power output commands or one or more temperature commands.

[0036] With reference to the drawings, the figure 1 represents a cooking system according to the invention, including in particular a cooking plate 10, a cooking utensil 20, and a remote electronic device 30.

[0037] Generally speaking, cooktop 10 may include: at least one induction cooking zone, and here, three induction cooking zones A, B and C are provided, a control unit 11 arranged to apply temperature or power instructions to the induction cooking zones A, B or C, a communication module 12 capable of exchanging information with a communication module 22 of the cooking utensil 20, a user interface 13 arranged to allow the user to select at least one step of at least one cooking recipe, local storage means 14 connected to the communication module 12 of the hob 10 and / or to the communication module 22 of the cooking utensil 20, arranged on the cooking utensil 20 and / or the hob 10, and arranged to store: at least one step of at least one cooking recipe, said at least one step comprising a series of time-bound temperature or power instructions,a control unit 15 suitable for connection to the control unit 11 of the hob 10 (or induction hob), and to the communication module 12 of the hob 10 or indirectly to the communication module 22 of the cooking utensil 20. ,

[0038] As for cooking utensil 20, it may include: the communication module 22 capable of exchanging information with the communication module 12 of the hob 10, a user interface 23 arranged to allow the user to select at least one step of at least one cooking recipe, local storage means 24 connected to the communication module 12 of the hob 10 and / or to the communication module 22 of the cooking utensil 20, arranged on the cooking utensil or the hob, and arranged to store: at least one step of at least one cooking recipe, said at least one step comprising a series of time-spanning temperature or power instructions, a control unit 25 capable of being connected to the control unit 11 of the hob 10, via the communication module 22 of the utensil and via the communication module 12 of the hob 10.

[0039] Thus, the control unit 15, 25 is located either in the cooking plate 10 or in the cooking utensil 20.

[0040] The cooking utensil 20 may also include a sensor 26, which can detect a magnetic field and / or a temperature, and connected to the communication module 22 of the cooking utensil 20. A battery or cells may also be provided to power the electrical devices provided in the cooking utensil 20 or a system capable of recovering energy and transforming it into electrical energy.

[0041] The remote electronic device 30 is here a mobile phone, but it could be a connected assistant, a tablet, or even a laptop or any type of terminal with a human-machine interface and a means of connecting to the system. In any case, the remote electronic device 30 may include: means of communication to establish a connection with the communication module 22 of the cooking utensil 20 or with the communication module 12 of the hob 10, or with a remote server, a user interface 33 arranged to allow the user to select at least one step of at least one cooking recipe, optionally a memory unit for storing data.

[0042] The system may also include, for example, at least one remote server, accessible via a network such as the internet.

[0043] At the very least, at least one of the hob 10 or cooking utensil 20 includes one of the following: a user interface 13 or 23 arranged to allow the user to select at least one step of at least one cooking recipe, local storage means 14 or 24 connected to the communication module 12 of the hob 10 and / or to the communication module 22 of the cooking utensil 20, arranged to store: at least one step of at least one cooking recipe, said at least one step comprising a series of time-spanning temperature or power instructions, a control unit 15 or 25 suitable for connection to the control unit 11 of the hob 10, and to the communication module 22 of the cooking utensil 20 or to the communication module 12 of the hob 10.

[0044] As explained below, one aspect of the invention is to provide a safe cooking system that allows the heating of the cooking utensil 20 placed on an induction cooking zone A, B, or C of the cooktop 10 to be controlled. As seen above, the control unit and local storage means are located on the cooktop 10 or on the cooking utensil 20. Consequently, the power or temperature instructions corresponding to the recipe are sent to the control unit 11 of the cooktop 10 from the cooktop 10 or the cooking utensil 20. Finally, the user interface that receives confirmation of the selected recipe is also located on the cooktop 10 or on the cooking utensil 20: the user is therefore in the immediate vicinity of the cooking unit and sees the system configuration before confirming the start of cooking.

[0045] In detail, the figure 2 represents a first example of a cooking system with the cooking utensil 20 placed on an induction cooking zone A of the hob 10, during a first phase of use.

[0046] According to the implementation of the figure 2 , the cooking utensil 20 includes the user interface 23, the control unit 25 and the local storage means 24, the cooking plate 10 being devoid of these elements.

[0047] In the first phase, the user placed the cooking utensil 20 on the induction cooking zone A of the hob 10 and initiated the connection between the devices. Connections based on the Bluetooth communication protocol are possible, for example, but other protocols can also be used.

[0048] In particular, the communication module 22 of the cooking utensil 20 pairs with the communication module 12 of the hob 10, and also with the remote electronic device 30. The communication module 12 of the hob 10 can also pair with the remote electronic device 30.

[0049] It is also planned to locate the induction cooking zone that receives the cooking utensil 20. Several actions are possible for this purpose. For example, the user interface 33 of the remote electronic device 30 can allow the user to select the induction cooking zone A, B, or C on which the cooking utensil is placed. Alternatively, the sensor 26 of the cooking utensil can be used to detect a magnetic excitation produced by the induction cooking zone A, or a temperature rise resulting from a test excitation emitted by the induction cooking zone A. Following this recognition, the control unit registers that the cooking utensil 20 is indeed on the induction cooking zone A. The cooking unit is thus formed by the selected induction cooking zone A and the cooking utensil 20.

[0050] Once the pairing is complete, and as shown in the figure 3 , the user in a second phase, from the remote electronic device 30, can send a recipe to be executed automatically to the cooking utensil 20, which will store the instructions in the local storage means 24.

[0051] Finally, at the end of this second phase, the user can confirm the selection of the cooking recipe to be executed on the user interface 23 of the cooking utensil 20. A confirmation button could be provided, for example.

[0052] Next, and as the figure 4 In a third phase, the cooking system receives information that the cooking utensil 20, when combined with the induction cooking zone A, has determined a cooking sequence. Therefore, the control unit 25 of the cooking utensil 20 can send temperature and / or power instructions and settings to the control unit 11 to carry out the user-selected function. It should be noted that in this third phase, the remote electronic device 30 does not send any data to the cooking zone 10, and in particular, no data / setup / instruction is sent from the remote electronic device 30 to the control unit 11 of the cooking zone 10, as indicated by the crossed arrow in the diagram. figure 4 .

[0053] In other words, cooking is controlled exclusively from the control unit 25, which is integrated into the cooking utensil 20, itself placed on the induction cooking zone A. This control is only activated if the control unit 25 receives: Firstly, information is provided to determine which induction cooking zone receives a cooking utensil, followed by a second confirmation of the recipe to be executed, via a local user interface, ensuring that the user has seen that everything is in order at the time of confirmation. The cooking process is safe, since cooking is initiated using a specific induction cooking zone and a recipe that the user has confirmed after observing the system. Furthermore, the control unit 25, via the established connections, is the only (and therefore local) component capable of independently controlling the cooking process.

[0054] During cooking, in a fourth phase, an execution report can be generated. For this purpose, the control unit 25 can, for example, record the cooking time, receive information about the temperature of the cooking utensil 20 via the sensor 26, and send a report to the user's remote electronic device 30, as shown in the diagram. figure 5 In this fourth phase, it should also be noted that the remote electronic device 30 does not send any data to the cooktop 10, and in particular, no data / instructions / commands are sent from the remote electronic device 30 to the control unit 11 of the cooktop 10, as shown by the crossed arrow in the figure 5 .

[0055] There figure 6 represents a second example of a cooking system with the cooking utensil 20 still placed on an induction cooking zone A of the hob 10, during a first phase of use.

[0056] According to the implementation of the figure 6 The cooking plate 10 includes the user interface 13, the control unit 15 and the local storage means 14, the cooking utensil 20 being devoid of these elements.

[0057] The operating principle is the same as for the cooking system described in the figures 2 à 5 and will therefore not be repeated. It should be noted, however, that in this embodiment, the user can confirm the selection of the cooking recipe to be executed on the user interface 13 of the cooktop 10. A confirmation button could be provided, for example. In other words, the cooktop includes at least part of the user interface, and the second confirmation signal is received by the control unit 15 if the user selects at least one step of at least one cooking recipe on the user interface 13.

[0058] Furthermore, as alternatives to the examples above, it is entirely possible to consider installing both in the cooking plate 10 and in the cooking utensil 20 a control unit and / or local storage means.

[0059] There figure 7 summarizes the steps implemented when using the cooking system, both for the first example of figures 2 à 5 than for the second example of the figure 6 .

[0060] At the start of use, two sets of steps are implemented. On the one hand, steps E1 to E4 relate to the communications exchanged between the elements of the cooking system, before the start of cooking, and on the other hand, steps E'1 and E'2 relate to the formation of a cooking set (determination of the induction cooking zone receiving the cooking utensil).

[0061] In detail, step E1 corresponds to establishing a connection between the remote electronic device 30 (a mobile phone in the embodiments illustrated previously) and the communication module 12 of the hob 10, and the communication module 22 of the cooking utensil 20.

[0062] As seen above, pairing of communication devices / modules can be considered according to the Bluetooth® communication protocol, but other communication modes can also be considered (near field communication known as "NFC", wireless radio wave communication known as "WIFI", wireless light wave communication known as "LIFI"...).

[0063] Step E2 then corresponds to loading from the remote electronic device 30 to the local storage means 14 of the cooking plate 10, and / or the local storage means 24 of the cooking utensil 20: at least one step of at least one cooking recipe, said at least one step comprising a series of instructions for temperature or power settings spread over time.

[0064] Step E3 corresponds to selecting on the user interface 13 of the hob 10 and / or the user interface 23 of the cooking utensil 20 and / or the user interface 33 of the remote electronic device 30 the step of the recipe to be executed.

[0065] Step E4 involves confirming locally on the user interface 13 of the cooktop 10 and / or the user interface 23 of the cooking utensil 20 the step of the recipe to be executed. In other words, this confirmation cannot be given from the remote electronic device 30.

[0066] Step E'1 corresponds to establishing a connection between the communication module 12 of the hob 10 and the communication module 22 of the cooking utensil 20. This step E'1 can be included in step E1 above.

[0067] Step E'2 involves determining which induction cooking zone (A, B, or C) the cooking utensil 20 is placed on. To this end, the user can be allowed to select the induction cooking zone via one of the user interfaces, or an induction cooking zone can be activated and its activation detected and confirmed by the sensor 26 on the cooking utensil 20, or by another detection device on the cooktop 10, for example. This step E'2 can be initiated by the user, or automatically (and repeated periodically), for example, following step E1 of the first series of steps, once a connection with the cooking utensil is established.

[0068] Step E5 corresponds to the reception by the control unit 15 of the cooking plate 10 or the control unit 25 of the cooking utensil 20 of: i- information that the cooking utensil 20 is indeed on the determined induction cooking zone, ii- confirmation of the culinary recipe step to be executed.

[0069] From the receipt of these two pieces of information, the control unit 15 of the cooking plate 10 or the control unit 25 of the cooking utensil 20 can send to the control unit 11 the power and / or temperature instructions which correspond to the part of the cooking recipe.

[0070] Cooking step E6 can take place safely. The cooking utensil 20 and the cooking plate 10 form a kind of closed circuit, and the cooking is controlled by the control unit which follows the selected recipe, and can however adjust the instructions based, for example, on feedback from the sensor 26 of the cooking utensil 20. It is possible to send intermediate reports or summaries to the remote electronic device 30, before the end of cooking, which corresponds to step E7.

[0071] It may be considered to periodically restart step E'2 to check that the cooking utensil is still on induction cooking zone A, even during step E6.

[0072] Also, during use, and after the E5 reception step: confirmation of the cooking recipe, and / or confirmation that the cooking utensil 20 is indeed on the designated induction cooking zone, It may happen that the user decides to change the utensil, the recipe, the induction cooking zone, or to interrupt the cooking process. This intention is either communicated to the control unit via a user interface, or the control unit detects, for example, a break in the cooking system (induction cooking zone - cooking utensil). Generally, after receiving the user's intention to change / stop, or after detecting a break in the cooktop-utensil combination, the control unit will stop sending instructions to the control unit 11 and may wait to receive them again. confirmation of the cooking recipe, confirmation that the cooking utensil 20 is indeed on the designated induction cooking zone, before sending instructions again to control unit 11.

[0073] The implementations described above are in no way limiting to the invention. In particular, the cooktop 10 may include, in addition to the induction cooking zone, non-induction cooking zones, and the cooking utensil 20 or the cooktop 10 may have additional functionalities (sending information directly to the remote electronic device 30, direct connection to an internet network, etc.). The simultaneous use of several induction cooking zones, each receiving a cooking utensil 20, is also conceivable, so that several cooking sets are managed simultaneously or sequentially.
