Definitions
- This invention relates to a method for operating an oven, a device for operating an oven and an oven, and more particularly a method and a device for operating an oven through the image of its load.
- This relates here to a food product cooking oven and more specifically, but not exclusively, for « grande cuisine Ltd
- the state of the art includes DE 100 63 694 A1 and EP 2192351 A2 .
- An oven comprises walls and a door delimiting a cooking cavity.
- a cavity is adapted for receiving removable cooking supports, including metallic ones.
- removable cooking supports could be a carriage or kitchen tools such as for instance, a grid, a container or cooking plates.
- Such removable cooking supports are adapted for receiving food products to be cooked or for supporting other removable cooking supports.
- the operation of an oven could comprise starting, modifying or stopping different operating cycles of the oven, such as a cleaning cycle, a ventilation cycle, or heating cycles, such as for instance a preheating cycle, different cooking cycles or a vapour producing cycle.
- Some of these operating cycles of an oven could require the presence of some cooking supports in the cooking cavity of the oven or even the closure of the door of the oven or still, the obstruction, through an obturator, of an opening provided in the walls of the oven.
- a method for operating an oven is known, based on the use of capacitive sensors for detecting the presence or the absence of a cooking support for each sensor, at each stage.
- the sensors to be used in such a solution, positioned in the cooking cavity of the oven result, more specifically, in oven jamming, clamping, cleaning, thermal behaviour and detection inaccuracy problems.
- such sensors, arranged at different stages of the cooking cavity do not allow the nature of the cooking supports to be detected in the kitchen tool elements.
- the invention of the present application aims at detecting the possible presence of supports in the oven and, if necessary, the nature of such supports, on the one hand, and at adapting the operation of an oven accordingly, on the other hand.
- This invention thus relates to, first of all, a method of operating an oven with a cooking cavity adapted for receiving removable cooking supports, wherein food products are cooked on said cooking supports according to determined cooking parameters, characterized in that:
- adaptive of the cooking parameters both means the ability, in the absence of cooking supports, to adapt the parameters for operating the oven, for example stopping the oven, that is stopping the operation thereof, or forbidding an operating cycle of the oven.
- the step of detection of the possible presence of removable cooking supports in the cavity of the oven comprises the following steps:
- a sensor inside the cooking cavity of the oven and the use of a given characteristic of the signal allows the possible presence, and optionally the nature, of any cooking supports to be determined in the cavity of the oven.
- One or more values of one or several characteristics of one or more signals could be used for determining the possible presence, and optionally the nature and/or the number of any cooking supports being present in the cooking cavity of the oven.
- Different characteristics of the signal may be used, such as, for example, the amplitude of the signal, the power of the signal, the phase of the signal, the variation of the amplitude of the signal as a function of time, the phase variation of the signal as a function of time, etc. and this, at one or more given frequencies of the signal.
- the number of removable supports in the cooking cavity is preferably determined.
- a cooking cycle of the oven may be selected or adapted when a number of removable cooking supports has been determined.
- the detection of the number of cooking plates being present in the cooking cavity of the oven may allow to select or to adapt a cooking cycle of the
- the possible presence of at least one removable wall element of the cavity of the oven is detected before adapting the cooking parameters.
- starting a vapour production cycle in the cavity of the oven might be interrupted or forbidden when the absence of a removable wall element of the oven has been determined.
- the method further comprises a step wherein the determined value is compared with at least one reference value so as to determine the presence of cooking supports in the cooking cavity of the oven.
- a comparison allows a reliable detection of the presence of cooking supports or removable wall elements in the cooking cavity of the oven.
- the method may further comprise a preliminary step wherein a reference value is determined corresponding to the presence of at least one removable cooking support identified in the cavity of the oven.
- the determination of the nature of the removable cooking supports being present in the cavity of the oven occurs through comparing the determined value with at least one reference value associated with the nature of at least one removable cooking support being identified.
- the nature of the cooking supports being present in the cooking cavity of the oven is thus reliably determined through comparing with references of cooking supports being identified, thereby making the determination of the nature of supports reliable.
- the method may further comprise a preliminary step wherein a reference value is determined corresponding to the presence of at least one removable cooking support identified in the cavity of the oven.
- a signal being emitted at a given frequency a plurality of signals is emitted at different frequencies in the cooking cavity of the oven, a value of a characteristic is determined for each received reflected signal, at least one remarkable value is determined amongst the plurality of determined values so as to detect the possible presence, and optionally the nature, of any cooking supports in the cavity of the oven.
- the analysis of the determined values allows at least one remarkable value to be determined. This or these remarkable values are specific of the present cooking support(s) or the removable wall elements absent in the oven. A remarkable value could be, for example, a maximum.
- the characteristic of the signal is its power and the remarkable value is the maximum power so as to determine a resonant frequency, associated with an image of the oven, of the cooking cavity amongst the plurality of frequencies of the signals being emitted.
- the power of a signal being easy to determine, this simplifies both the processing of the signal, the determination of the value of a characteristic of the received reflected signal and the determination of the presence, and optionally of the nature, of the removable cooking supports in the cooking cavity from the determined value.
- the characteristic of the signal is its phase.
- the signal is an electromagnetic or a sound signal.
- An electromagnetic signal may be emitted and received from outside the cooking cavity of the oven, allowing to prevent having to arrange one or more sensors inside the cooking cavity and thus to overcome oven jamming, clamping, cleaning, and thermal behaviour problems.
- An electromagnetic signal as a result of its characteristics such as, for example, its power, further ensures the accurate determination of a characteristic of the received reflected signal and thus a good reliability of the determination of the presence, and optionally of the nature or the number of cooking supports in the cooking cavity.
- the emission of the signal occurs during a time interval and the reception occurs during a distinct subsequent time interval.
- the invention also relates to a device for operating an oven, configured for implementing a method, such as defined hereabove, for operating an oven with a cooking cavity adapted for receiving removable cooking supports, wherein food products are cooked on said cooking supports according to determined cooking parameters, characterized in that said device comprises:
- the invention also relates to an oven comprising the device of the invention such as defined above.
- Figs. 1 and 2 show an oven 10a and Figs. 3 to 6 an oven 10b, each comprising walls defining a cavity 12 and the front side of which is provided with a door 14.

- a carriage 20b comprises a frame 24 arranged for receiving a plurality of cooking supports 20c, such as cooking plates or trays, on a plurality of different levels.
- the oven 10b When the carriage 20b is out of the cavity 12 of the oven 10b, as shown on Fig. 5 , the oven 10b has an opening 26 arranged under its door and through which a liquid or gas stream 27, such as for example vapour, may circulate.
- a removable wall element 28 of the oven having the shape of an anti-leakage plate, may thereby be mounted on said opening 26 so as to prevent such a stream from circulating, as illustrated on Fig. 6 .
- Fig. 7 illustrates the system according to the invention.

- the receiving module 44 comprises an antenna 45 arranged so as to receive one or more signals being reflected in the cavity 12 of the oven 10 by the walls of the oven and/or by the cooking supports 20 present in the cavity 12 of the oven 10.
- the antenna 43 of the emission module 42 and the antenna 45 of the reception module 44 may be different or the same.
- the emission module 40 and the reception module 44 may each comprise several antennas respectively for emission and reception of signals. Such antennas may be different or identical.
- the analysis module 46 allows to analyze the received reflected signals by the antenna 45 of the reception module.
- the analysis may comprise determining a value of a characteristic of the received reflected signal (s). For example, the power of each received reflected signal could be analyzed so as to determine the possible presence of any cooking support in the cavity of the oven as described hereinafter with reference to Fig. 9 .
- the determination module 50 allows to determine the nature and optionally the number of cooking supports 20 being present in the cavity 12 of the oven 10.
- the parameter adaptation module 60 allows the oven to be operated while adapting the operation thereof to the absence or the presence, even to the nature or to the number, of the cooking supports 20 being detected in the cavity 12 of the oven 10 through the adaptation of the cooking parameters of the oven 10.
- the method according to the invention is a method of operating an oven 10 with a cooking cavity 12 being intended for receiving removable cooking supports 20, wherein food products are cooked on said cooking supports 20 according to determined cooking parameters.
- the detection module 40 of the device 30 allows to detect the possible presence of cooking supports 20 in the cavity 12 of the oven 10.
- such a detection step E1 comprises a first step E1a consisting of emitting, by the emission module 42, one or more signals in the cavity 12 of the oven 10.
- signals may be, for example, electromagnetic or sound.
- signals may be emitted in a frequency band ranging between, for example, 430 MHz and 450 MHz.
- a plurality of signals may be emitted starting at 430 MHz and progressively increasing the frequency step by step up to 450 MHz, for example using 400 measurements.
- the signals emitted in the cavity 12 of the oven 10 will be reflected on the walls of the oven 10 and, if present in the cavity 12, on the cooking supports 20.
- the reception module 44 then received such reflected signals in a second step E1b. Otherwise stated, the received signal is measured in the emitted frequency.
- the emission and the reception of signals may be alternated in time. For example, the emission may occur during 30 ⁇ s, followed by the reception during 1 ⁇ s.
- the analysis module 46 in a step E1c, analyzes the received reflected signals and detects the possible presence of any cooking supports 20 in the cavity 12 of the oven 10.
- the emission module 42 sends a plurality of electromagnetic signals, each signal having a frequency different from the others.
- the received reflected signals corresponding to the signals sent in the cavity 12 of the oven 10 will have different powers therebetween.
- the value of the power of each received signal may be stored.
- the device 30 may comprise a memory.
- the signal(s) with the highest powers has or have frequencies corresponding to the resonant frequencies of the cavity of the oven. This or these values is or are a characteristic of the cavity and varies or vary in the presence of cooking supports 20 and as a function of the nature of said cooking supports 20 or in the absence of a removable wall element 28.
- the oven 10 When the oven 10 is empty, that is when it does not comprise any cooking supports 20 in its cavity 12, this corresponds to a certain resonant frequency, or a certain image of the load of the (empty) oven 10 referred to as the initial image. Similarly, when the cavity 12 of the oven 10 comprises one or more cooking supports 20, this corresponds to one or more different resonant frequencies. Thus, to each different load of the oven 10, one or more values of resonant frequency correspond, and therefore an image specific to the load of the oven 10. The presence of cooking supports 20 is then established when the current image of the load of the oven 10 does not correspond to the image of the empty oven 10, as illustrated on Fig. 10 . Similarly, the absence of cooking support 20 is established when the current image of the load of the oven 10 corresponds to the initial image of the empty oven 10.
- step E2 In the case of the presence of cooking supports 20 in the cavity 12 of the oven 10 (step S1), their nature may be determined in a step E2.
- the nature of the cooking supports 20 is determined by the determination module 50.
- the value of the analyzed characteristic of the signal giving an image of the load of the oven 10, for example from the resonant frequency(ies), may be compared to one or more reference images, thereby allowing to identify the load of the oven 10 and thus to determine the nature of the cooking supports 20 present in the cavity 12 of the oven 10, as illustrated on Fig. 11.
- Such reference images could be achieved, for example, in the plant upon the manufacture of the device 30 and stored in a memory that the device 30 (or the oven 10) may include to this end.
- the determination module may determine, by comparison with reference images, at a step E2', the number of cooking supports 20 being present in the cavity 12 of the oven 10.
- the cooking parameters are adapted to the absence or the nature of the cooking supports 20.
- Such an adaptation is implemented by the adaptation module of the cooking parameters 60 and may allow the operation of the oven 10 to be modified according to the presence, and optionally the nature and/or the number, of cooking supports 20 in the cavity 12 of the oven 10.
- the cooking parameters of the oven 10 may thus be adapted automatically as a function of the absence or the presence, and optionally of the nature, of cooking supports 20 in the cavity 12 of the oven 10 or removable wall elements 28.
- the adaptation of the cooking parameters of the oven 10 may comprise, for example, forbidding, starting, stopping or adapting an operation cycle of the oven 10.
- An operation cycle of the oven 10 may be a cleaning cycle, a ventilation cycle, a preheating cycle, a cooking cycle or a vapour producing cycle in the cavity of the oven.
- a cleaning cycle may be started, for example, when the absence of removable cooking supports 20 has been determined in the cavity 12 of the oven 10, or even adapted or forbidden when the presence of removable cooking supports 20 has been determined in the cavity 12.
- the detection of the presence of kitchen tools in the cooking cavity 12 of the oven 10 may allow to adapt or to forbid a cleaning cycle of the oven 10.
- a ventilation cycle or a pre-heating cycle may be stopped when the absence of removable cooking supports 20 has been determined in the cavity.
- the detection of the absence of containers or cooking plates in the cavity 12 of the oven 10 allows to interrupt heating or ventilating the oven 10, for example at the end of a pre-heating cycle of the oven 10.
- Starting a cooking cycle of the oven 10 may be forbidden when the absence of some of the removable cooking supports 20 has been determined in the cavity 12. Thus, the detection of the absence of containers or cooking plates in the cavity of the oven may allow a cooking cycle to prevent from starting as there is no product to be cooked in the cooking cavity 12 of the oven 10.
- a cooking cycle of the oven 10 could be, for example, started or adapted when the presence, and optionally the nature, of some removable cooking supports has been determined.
- Starting a vapour production cycle in the cavity 12 of the oven 10 could be interrupted or forbidden when, for example, the presence, and optionally the nature, have been determined of one or more given removable cooking supports 20 in the cavity 12. For example, it may be useful to detect the absence of a carriage 20b or a removable wall element 28 of the oven in order to forbid the production of vapour.
- Figs. 10a to 10d illustrate test curves carried out with different loads of the oven, that is in the cavity of the oven, with an emission/reception antenna and for two different positions of said antenna.
- Fig. 10a shows a first load of the oven, for example a cooking plate.
- the frequency response of the cavity between 395 and 465 MHz shows a peak around 404 MHz being characteristic of said first load.
- Fig. 10a shows a first load of the oven, for example a cooking plate.
- the frequency response of the cavity between 395 and 465 MHz shows a minimum peak of about -34 dB around 404 MHz being characteristic of said first load.
- Fig. 10b shows a second load of the oven, for example a cooking container.
- the frequency response of the cavity between 395 and 465 MHz shows two minimum peaks of about -24 and - 17 dB around respectively 428 and 435 MHz, being characteristic of said second load.
- Fig. 10c shows a third load of the oven, for example two cooking plates.
- the frequency response of the cavity between 395 and 465 MHz shows two minimum peaks, of about -33 dB around respectively 404 and 434 MHz, being characteristic of said third load.
- Fig. 10d shows a fourth load of the oven, for example when it is empty.
- the frequency response of the cavity between 395 and 465 MHz shows a minimum peak of about -34 dB around 418 MHz being characteristic of said fourth load.
- the curve representing the image of the oven varies and one or more peaks occur at different frequencies and with different intensities, that may be associated with the absence or the presence of support and, in the case of the presence, to the nature and/or the number of supports, for example comparing them with predetermined reference curves, for example in the plant.
