    [0001] The invention relates to the field of culinary articles. More particularly, the invention relates to a culinary article adapted for induction cooking which comprises means for measuring a magnetic field and associated communication means. PRESENTATION OF THE PRIOR ART In the prior art, there are known culinary articles which are heated by induction and which can communicate either with an induction table or with a remote module. Thus WO2010080738 discloses a system which comprises a culinary article heated by an induction table. The document describes a step of detecting the presence of the culinary article on the induction table. This is done by an analysis of the variation of a magnetic response received by the induction table and it is a device specific to the induction table that performs this operation. In the same way the induction table is able to identify the type of culinary item as a function of the magnetic response. This document also describes an intelligent handle integrated in the culinary article. This smart handle includes embedded electronics that can perform various functions and communicate with a communication module built into the induction hob. The peculiarity lies in the fact that this embedded electronics is powered independently. To achieve this power supply a device is installed in the handle or in the bottom of the culinary article in order to recover a portion of the induction energy. The aim sought in the document W02010080738 is to supply energy to the intelligent handle so that it is operational and communicating. A disadvantage encountered is that it is the induction table that manages all the detection operations and presence of the culinary article. The culinary article does not detect the presence or absence of a magnetic field and inform the induction table on the activation state of the generating focus on which it is positioned. There is communication and possible information exchange between the culinary article and the induction plate only when the induction table generates a magnetic field that supplies energy to the intelligent handle of the culinary article.
    [0002] The object of the present invention is therefore to overcome the aforementioned drawbacks and to allow a cooking utensil to independently detect the presence or absence of a magnetic field on a firebox, to inform the induction table and associate the activated firing chamber with the culinary article. By independent means that even if the focus on which the culinary article is positioned is extinguished, the culinary article can transmit information. This object is achieved with the aid of a cooking utensil which includes a cooking surface compatible with induction cooking and the cooking utensil comprises a signal processing unit connected to a device for measuring a magnetic field and to a bidirectional wireless communication module. According to one characteristic of the invention, the signal processing unit generates at least one confirmation of the presence of a magnetic field. According to one characteristic of the invention the culinary article comprises a device for powering up the signal processing unit and / or the wireless bidirectional communication module. According to one characteristic of the invention, the signal processing unit comprises a computer and a memory. According to one characteristic of the invention, the signal processing unit is programmable wirelessly and remotely. According to a characteristic of the invention, the signal processing unit and / or the wireless bidirectional communication module are removable from the culinary article.
    [0003] According to a characteristic of the invention the culinary article comprises a display connected to the signal processing unit. According to one characteristic of the invention the culinary article comprises a control unit connected to the signal processing unit. According to one characteristic of the invention the culinary article comprises a temperature sensor connected to the signal processing unit. According to one characteristic of the invention, the device for measuring the magnetic field is a thermistor. According to another characteristic of the invention, the device for measuring the magnetic field is a thermocouple.
    [0004] According to yet another characteristic of the invention, the device for measuring the magnetic field is a magnetoresistance sensor. According to yet another characteristic of the invention the device for measuring the magnetic field is made from a coil that can have one or more turns.
    [0005] According to one characteristic of the invention, the device for measuring the magnetic field is positioned in or on the cooking surface of the culinary article. According to one characteristic of the invention, the device for measuring the magnetic field is positioned in the handle of the culinary article.
    [0006] According to a characteristic of the invention the culinary article comprises an energy recovery device composed of receiver coils which transmit the recovered energy to the signal processing unit and / or to the communication module 5 of the culinary article. . The invention also relates to a method of pairing with a focus of an induction table of a culinary article as described above. The induction table comprises a communication device and a computing unit. The method comprises the following steps: - generation of a magnetic flux by the focus of the induction table, - powering up the signal processing unit and / or the wireless bidirectional communication module by an action on the device for energizing, 10 - positioning the culinary article on the magnetic flux generating furnace, - detecting the magnetic flux of the induction cooker furnace by the device for measuring the cooking article positioned on this furnace, recovery and processing by the signal processing unit of the culinary article of the signal detected by the measuring device of the culinary article, - recovery of the signal processed by the communication module, the processed signal comprising at least one information confirmation of the presence of the magnetic field, - transmission by the communication module of this information, 20 - reception of this information by the communication module of the induction hob, - processing of this information received by the calculation unit of the induction hob, - pairing of the generator hearth and the emitting cooking utensil. The aims, aspects and advantages of the present invention will be better understood from the description given below of a particular embodiment of the invention given by way of non-limiting example, with reference to the accompanying drawings. in which: - Figure 1 is a sectional view of a culinary article in a first embodiment; - Figure 2 is a sectional view of a system of an induction table and a cooking utensil; - Figure 3 is a sectional view of a culinary article in a second embodiment; - Figure 4 is a top view of a culinary article; - Figure 5 is a top view of a culinary article; DESCRIPTION With reference to FIG. 1, a culinary article 1 comprises a cooking surface 2. This cooking surface 2 is compatible with induction cooking. By this is meant that in the presence of a magnetic field or flux the cooking surface 2 rises thermally. The culinary article 1 also includes a processing unit 4 of the signal. By signal processing unit 4 will be understood an electronic unit capable of performing primary logic operations on input signals and returning a result of this operation as output. It will be seen later that, in the context of the invention, this signal processing unit 4 generates at least one confirmation of the presence of a magnetic field. The culinary article 1 also comprises a device 3 for measuring a magnetic field connected to this processing unit 4. The connection between these two elements (3, 4) is wired. The device 3 for measuring a magnetic field is a device that makes it possible to detect and measure a magnetic field by changing the physical state of the device 3 when it is in the presence of a magnetic field. Near field of magnetic field Without exceeding the scope of the invention, the device 3 for measuring the field is a coil comprising one or more turns, thus when a magnetic flux passes through the coil, a voltage is induced across the coil. Induced is the image of the magnetic flux.In Figure 4, the coil comprises a single turn called conductor wire 13. This conducting wire 13 forming a loop will detect the presence of a magnetic field. Another non-illustrated variant of the device 3 for measuring the field is a thermistor with Negative Temperature Coefficient of the NTC thermistor type. The CTN thermistor with its connection wires constitutes a current loop. When a magnetic flux passes through this loop, an induced image voltage of this magnetic flux appears at the terminals of the CTN thermistor. In another variant embodiment the device 3 for measuring the magnetic field is a thermocouple 14 as illustrated in FIG. 5. The thermocouple 14 constitutes a current loop. If a magnetic flux passes through this loop, an induced image voltage of this flux appears at the terminals of the thermocouple 14. In yet another variant, not illustrated, the device 3 for measuring the magnetic field is a magnetic field sensor. This sensor may be a Hall effect sensor or a magnetoresistance type sensor. This sensor makes it possible to measure a magnetic field level and thus to detect the presence of magnetic flux in its close environment. The device 3 for measuring the magnetic field is positioned in the cooking surface 2 of the cooking utensil 1. Without however departing from the scope of the invention, the device 3 for measuring the magnetic field can be positioned in any part of the culinary article 1 as a handle 21 when it includes one as can be seen in Figures 1 to 5. This handle 21 may be fixed or removable relative to the culinary article 1. The culinary article 1 also comprises a bidirectional communication module 5 which is connected to the signal processing unit 4. This bidirectional communication module 5 makes it possible to transmit at least one information confirming the presence of a magnetic field. In the context of the invention, this communication module 5 is a point-to-point communication module.
    [0007] In the context of the invention the processing unit 4 of the signal and the communication module 5 are included in the handle 21 and this handle 21 can be removable from the culinary article 1. In other embodiments, that It can be an infrared module, a near field communication module of the NFC type, or a Bluetoote module. In the context of the invention as visible in Figure 2, the communication module 5 transmits at least one confirmation information of the presence of the flux or the magnetic field to an induction cooktop 18, conventionally called induction table 18 This induction table comprises at least one fireplace 18a and the fireplace 18a comprises a coil 17 which generates a flux or a magnetic field. For this purpose, the induction hob 18 comprises a communication device 19 and a calculation unit 20 for receiving information from the cooking utensil 1.
    [0008] As can be seen in FIGS. 1 to 5, the culinary article 1 comprises a device 6 for energizing the signal processing unit 4 and / or the wireless bidirectional communication module. This power-on device 6 is conventionally called a switch.
    [0009] There are different ways of supplying power to the signal processing unit 4 and / or the wireless bidirectional communication module. Classically one can use a battery or batteries. The batteries can be positioned in the handle 21. Another method is to recover the magnetic energy generated by the coil 17 of the hearth 18a on which the cooking utensil 1 is positioned. This energy recovery can be done via a device energy recovery composed of receiving coils and transmitting the current thus recovered to the processing unit 4 of the signal and / or the communication module 5 for power supply and provided that the power device 6 is activated. This energy recovery device (not shown) can be positioned at or in the cooking surface 2 of the cooking utensil 1 or in the handle 21 of the cooking utensil 1. When the assembly is de-energized, the culinary article 1 can be positioned on the induction table 18 without the processing unit 4 of the signal and / or the communication module 5 are active. This increases the efficiency and safety of use of the culinary article 1. The processing unit 4 of the signal of the culinary article 1 also comprises a calculator 7 and a memory 8 as can be seen on the FIG. 3. This memory 8 makes it possible to store various types of information such as the type of utensil, cooking profiles, temperature profiles of the cooking utensil 1. In one embodiment shown in FIG. culinary article 1 comprises a control unit 10 connected to the processing unit 4 of the signal.
    [0010] By control unit 10 is meant a unit on which a user can act. Through this control unit 10, a user can therefore send control information to the processing unit 4 of the signal. Still with reference to FIG. 3, the culinary article 1 comprises a temperature sensor 11 connected to the processing unit 4 of the signal. This sensor 11 can send a temperature information to the processing unit 4 of the signal. Without departing from the scope of the invention, the temperature sensor 11 can be positioned at the level of the cooking surface 2 of the cooking utensil 1 or on a wall of the cooking utensil 1 as can be seen in FIG. The processing unit 4 of the signal is programmable wirelessly and remotely by a portable communication terminal 22. The data exchange between the memory 8 of the signal processing unit 4 and the communication terminal 22 can be done in both ways. A user can therefore remotely control the processing unit 4 of the signal. When the processing unit 4 of the signal is coupled to the control unit 10 and / or to the temperature sensor 11, the computer 7 of the signal processing unit 4 allows, according to the data transmitted by the unit 10 and / or by the temperature sensor 11, to return a setpoint information. This setpoint information is transmitted via the communication device 19 of the induction table 18 to the calculation unit 20 of the induction table 18. The calculation unit 20 then makes it possible to regulate the power generated by the coils 17 of the fireplace 18a activated. In an alternative embodiment the processing unit 4 of the signal and / or the wireless bidirectional communication module 5 are removable from the culinary article 1. In this case, the culinary article 1 also comprises a display 9 connected to the signal processing unit 4 and this display 9 makes it possible to display the information of the processing unit 4 of the signal. This display 9 is included in the handle 21 and the display 9 can be removable from the handle 21 and the processing unit 4 of the signal.
    [0011] In a non-limiting mode of operation, the invention also relates to a method of pairing a hearth 18a of the induction table 18 with the culinary article 1 as described above. A user lights one of the fires 18a of the induction table 18 which will generate a magnetic flux through the hearth 18a of the induction table 18.
    [0012] The user must then turn on at least the signal processing unit 4 and / or the wireless bidirectional communication module by an action on the power-on device 6 of the culinary article 1. When this article 1 is positioned on the furnace 18a supplied, the device 3 for measuring the magnetic flux of the culinary article 1 detects the presence of a magnetic flux generated by the furnace 18a supplied and this information is recovered by the processing unit 4 of the signal of the culinary article 1. The communication module 5 retrieves this information in order to transmit it.
    [0013] The information sent includes at least one confirmation information of the presence of the magnetic field. This information is then received by the communication device 19 of the induction table 18 and the calculation unit 20 of the induction table 18 processes this information in order to match the furnace 18a generator with the culinary article 1.
    [0014] This system makes it possible to bring intelligence to the culinary article 1 thus enabling it to know the state of the home on which it is located and to communicate with its environment. In a variant of the information transmission step of the method described above it is also possible to transmit intrinsic information to the utensil such as the confirmation of the programmed heating power, and / or the adapted cooking profile. This information thus makes it possible to regulate the heating power in the case where this information is received by the induction table 18 as information of instructions. It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the embodiment of the invention described herein without departing from the scope of the invention defined by the appended claims.
