    The present invention relates to auxiliary cooking apparatus with a temperature sensor and an electronic circuit arrangement, which is supplied with an output value of the remperaturfühlers, wherein from the electronic circuitry data for controlling the temperature of a cooking hob heatable cooking vessel can be transmitted wirelessly to a receiving unit.
    In order to prepare tasty meals, depending on the food to be used, e.g. Meat, fish or vegetables to meet specific cooking temperatures. For example, when roasting meat depending on the preference of the guest a certain core temperature and at the same time a roast crust desired. For detecting the core temperature, plug-in thermometers are known in the food to be prepared, e.g. from DE 31 19 496 A1, DE 299 23 215 U1 and DE 10 2009 019 613 A1.
    In Sous-Vide cooking, food that has been welded into a plastic bag is cooked in a water bath. For this purpose, Sous-Vide devices are known which have an immersion heater, a temperature sensor for detecting the water temperature and a control electronics for controlling the immersion heater. The sous vide device can be hung as a unit, for example, on a water bath.
    In EP 1 239 703 A2 a cooking aid of the type mentioned is shown, which is used in particular for controlling the temperature of a water-filled cooking vessel or steam in a closed cooking vessel. The temperature sensor is mounted according to an embodiment on a shaft, on which various kitchen utensils, such as a wooden spoon, can be set. The cooking aid with the attached wooden spoon is set in a water-filled cooking vessel. In other embodiments, the cooking aid is inserted with removed kitchen utensil through an opening in a lid of a cooking vessel or hung on the edge of the vessel. The temperature is measured depending on the position of the temperature sensor relative to the cooking vessel at different locations with distance from the bottom of the cooking vessel. Similar devices are also apparent from DE 10 2013 218 785 A1 and DE 101 17 -545 A1, wherein in the latter document the lid of the cooking vessel with a ------------------- ---
    Sensor unit is provided for detecting the temperature.
    The object of the invention is to provide an advantageous cooking aid device of the type mentioned, by which facilitates the preparation of food and / or can be improved.
    According to the invention, this is achieved by a cooking aid with the features of claim 1.
    The cooking auxiliary device according to the invention is designed in the manner of a Stehaufmännchens, which rests on a flat, horizontal bottom of the cooking vessel in an erect condition (= rest position). Any change in the position of the cooking aid deviating from the erected state leads to a lifting of the center of gravity, so that the cooking aid by the acting gravitational field of the earth by itself straightens up. Thus, the cooking aid can be placed without special attention to the position of the cooking aid on the bottom of the cooking vessel, as it straightens by itself. Especially in commercial kitchens such user-friendly training is of particular importance. It is thus made possible in a simple way a temperature measurement at a defined location, wherein in an advantageous embodiment of the invention by means of the temperature sensor, the temperature of the bottom of the cooking vessel itself can be detected. In this case, the temperature sensor based on the erected state occupies the cooking aid on the floor, conveniently located directly on the ground, preferably by the temperature sensor is in the erected state of the cooking aid in the region of the lowest point of the cooking aid, with this rests on the ground.
    Using the cooking auxiliary device, a control of the temperature of the bottom of a cooking vessel can be made possible, for example, to perform a roasting process at a desired temperature. The cooking vessel may be empty or the bottom may be covered with an oil film. The------------------------------ -
    Cooking aid may also be conveniently used in conjunction with the control of a thicker, bottom-covering liquid layer, such as when baking or frying in the pan, e.g. with cooking oil, that is the case.
    The cooking aid may preferably be designed to detect temperatures of up to more than 200 ° C, preferably up to more than 250 ° C.
    For example, a temperature range up to 280 ° C can be provided.
    The electronic circuitry is conveniently spaced from the lowest point of the cooking aid, with which it rests in the erected state on the bottom of the cooking vessel in the vertical direction. The vertical distance of the electronic circuit assembly from the flat, horizontal bottom of the cooking vessel is based on the erected state of the cooking aid preferably at least 1 cm, more preferably at least 2 cm. The components of the electronic circuit arrangement, in particular semiconductor components, can thereby be protected from the action of the heat of the bottom of the cooking vessel.
    The auxiliary cooking appliance advantageously has at least one energy storage element. The energy storage element can supply the electronic circuit arrangement and optionally the temperature sensor with electrical energy. Preferably, the energy storage element of the cooking aid is a rechargeable battery or a capacitor. The
    Energy storage element of the cooking aid device can then be charged, for example by means of an external charging station, preferably wirelessly. In alternative embodiments, the energy storage element may also be removable and usable by the end user from the cooking aid device and usable battery, optionally rechargeable battery.
    The vertical distance of the energy storage element from the flat, horizontal bottom - of the cooking vessel is based on the erected state of ------------ -----------------
    Cooking aid conveniently at least 1 cm, preferably at least 2 cm. As a result, energy storage elements, which are usually particularly sensitive to temperature, are protected from the action of the heat of the bottom of the cooking vessel. It is particularly favorable if the energy storage element is arranged above the electronic circuit arrangement.
    One possible embodiment provides that the auxiliary cooking device has an energy harvesting device for supplying the electronic circuit arrangement and / or the energy storage element with electrical energy. Energy Harvesting facilities are used to generate electrical energy from existing outside the cooking aid energy sources in the area. These may in particular be magnetic stray fields of eddy currents of an induction hob. For these, electrical energy can be obtained by means of charging coils arranged in the auxiliary cooking appliance. Other energy harvesting devices, for example, for the recovery of electrical energy from the ambient temperature, are conceivable and possible. Such are known in other fields of technology. In the case of the use of an energy harvesting device, it could in principle be possible to dispense with an energy storage element. However, such is still advantageous to ensure a complete power supply and / or buffer peaks occurring in energy consumption.
    Preferably, the cooking aid is designed as a float. That the
    Cooking aid can float in a water bath and does not sink to the bottom of the cooking vessel. A possible application for a floating cooking aid is the preparation of food in sous vide cooking, also referred to as vacuum cooking. The food is cooked in a plastic vacuum bag at water temperatures below 100 ° C. An advantage of vacuum cooking is that by vacuuming significantly less volatile flavors, flavors and liquids from the food - can emerge. When heating water by means of a cooking surface (= --------------------- kitchen stove) forms in the shut off on the cooking vessel a natural flow movement in the water bath, in the At the bottom of the cookware heated water rises centrally in the cooking vessel to the water surface. The heated water flows radially outward near the water surface and sinks in the outer area of the water bath. By the floating cooking aid device, the exact temperature of the water bath can be measured in an area near the water surface, regardless of how much water is filled in the pot.
    The cooking aid is conveniently designed as a self-righting float. From an arbitrary inclined position, in which the auxiliary cooking device is introduced into the water bath, it thus again aligns itself in a defined self-erected, stable state. Thus, the cooking aid can be simply thrown by the end user into the water bath, without paying attention to a specific insertion position, wherein the temperature sensor is after the automatic assumption of the erected position of the cooking aid at the predetermined position below the water surface.
    Advantageously, it is provided that the electronic circuit arrangement is at least partially above the waterline of the cooking aid device in self-erected state of the floating in the water heater cooking aid. The waterline refers to the line in which the water level touches the outer surface of the cooking aid. In other
    In words, the waterline corresponds to the intersection between the plane in which the water surface of the water bath lies and the outer surface of the cooking aid. Since the electronic circuit arrangement is at least partially, preferably completely, above the waterline of the cooking aid device, the components of the electronic circuit arrangement, in particular semiconductor components, can be favorably protected from the action of the heat of the water bath. In this context, it is particularly favorable when the electronic circuit arrangement is at least at a distance of more than 1 cm above the waterline in the vertical direction.
    The energy storage element is located in the self-erected state of the floating in the water heater cooking aid advantageously above the waterline of the cooking aid, preferably also above the electronic circuitry. As a result, energy storage elements, which are usually particularly sensitive to temperature, are protected from the action of the heat of the water bath.
    Preferably, the cooking auxiliary device designed as a float is also suitable for detecting the temperature of an oil bath which can be heated by the cooking point.
    Thereby, for example, the temperature of a large amount of edible oil, e.g.
    Coconut oil, sunflower oil, etc., for example, for deep-frying food in a deep oil bath, are regulated exactly. Also in this field of application is advantageously provided that the cooking aid device is formed in the oil bath as a self-righting float. The electronic circuit arrangement is again in the self-erected state of the cooking aid floating in the oil bath at least partially, preferably completely, above the line in which the oil level touches the outer surface of the cooking aid. Also, the energy storage element is located in the self-erected state of a floating in an oil bath cooking aid advantageously above the line in which the oil level touches the outer surface of the cooking aid.
    Further features and details of the invention will be explained with reference to the embodiment of a cooking aid shown in FIGS. Show it:
    Figure 1 is a view of a cooking aid according to the invention in a schematic representation.
    Fig. 2 shows the application of the cooking aid device of Figure 1 (in a frying pan). _______Fig. FIG. 3 shows the cooking device floating in a water bath as shown in FIG. 1 (with sous vide cooking), with the cooking appliance in the self-erected state and - in dashed lines - in an inclined position deviating from the self-erected state, and FIG. 4 the cooking appliance in the erected state and - in dashed lines
    Lines - one of which deviates skewed position when placed on the bottom of the cooking vessel of FIG. 2.
    The cooking aid device 1 shown in the figures serves to detect and transmit the temperature measured by the temperature sensor 2 of the cooking aid device 1. The temperature sensor 2 is connected to electrical leads, not shown, with a schematically indicated electronic circuit 3 for detecting the output value of the temperature sensor 2. The electronic circuit 3 includes semiconductor devices, such as semiconductor devices. Analog / digital converter when using analogue temperature sensors,
    Microcontroller for data acquisition, memory components, etc. on. A measured value detection and processing module is designated by 3a.
    The electronic circuit arrangement 3 further comprises a communication module 3b, which serves the wireless communication with a later to be explained receiving unit 23 a hotplate 22.
    The auxiliary cooking device 1 is equipped with an energy storage element 5, from the energy of the electronic circuit 3 is available for their operation.
    The cooking auxiliary device 1 is designed in the manner of a standing mannequin, i. after placing the cooking aid device 1 on a flat, horizontal surface, ie in particular on the bottom 29 of a cooking vessel 21 which is flat and horizontal, in an arbitrary position this depends on itself in an erect condition (= of Fig. 4 in solid line shown rest state of the cooking aid 1). Each deviating from the idle state
    Oblique position of the cooking aid device 1 (= position shown in broken line ---------------------------- the cooking auxiliary device 1 shown in FIG. 4) leads to a Lifting the center of gravity. The trained in the manner of a Stehaufmännchens Kochhilfsvorrichtung 1 so directed by the acting gravity from any inclined position in which it is inclined to the erected state about any horizontal axis by any angle, even in the upright state (= rest position). so that the cooking auxiliary device 1 by the acting gravity by itself straightened up again.
    The raising of the auxiliary cooking device 1 from an inclined position when depositing on a bottom 29 of a cooking vessel 21 is indicated in Fig. 4 by an arrow in the direction of movement 11.
    The schematically indicated in Fig. 1 additional weight 6 can support the erection of any skew in the erected state.
    So-called Stehaufmännchen are basically known as children's toys.
    The cooking auxiliary device 1 can be moved freely on the bottom 29 of the cooking vessel 21 in the horizontal direction.
    In the exemplary embodiment, the cooking aid device 1 is rotationally symmetrical. In the erected state (= idle state) of the cooking auxiliary device 1, the longitudinal axis 4 of the rotationally symmetrical cooking auxiliary device 1 is aligned in the vertical direction, cf. Fig. 4. The auxiliary cooking device 1 could also be formed asymmetrically in another embodiment.
    Preferably, it is provided that in the erected state (= idle state) in which the cooking aid device 1 when depositing on the flat, horizontal bottom 29 of the cooking vessel 21, the temperature sensor 2 is located in the region of a lowest point of the cooking aid 1, and the ground 29 touched.
    This ensures that the temperature of the bottom 29 of the cooking vessel 21 with the introduced into the cooking vessel 21 Kochhilfsvorrichtung 1 reliably - can be measured. The cooking vessel 21 may in this case be empty or the bottom --------------------- may be covered with a liquid, in particular oil, e.g. to saute a dish. It may be a liquid film, in particular oil film, low height or a thicker liquid layer, in particular oil layer, for example, for baking out food, act.
    The cooking auxiliary device 1, as described in more detail below, be buoyant, which is preferred. In this case, it is conveniently provided that the cooking aid device 1 both with an empty cooking vessel 21 and with a filling of the cooking vessel 21 with liquid, such as water or oil, up to any height at which the cooking aid device 1 is not yet floating out any position in which the cooking auxiliary device 1 is inserted into the cooking vessel 21, erected in the erected state. The state assumed during any swimming of the cooking aid device 1 is described below.
    If the auxiliary cooking device 1 is not designed to be buoyant, it is advantageously provided that the cooking auxiliary device 1 can be filled with any liquid, in particular water or oil, from any position in which the cooking auxiliary device 1 is inserted into the cooking vessel 21 during any filling of the cooking vessel 21. erect in the erected state. In this case, however, it may be necessary due to the acting temperature load to fill the cooking vessel 21 at most so high that the electronic circuit arrangement 3 and / or the energy storage element 5 is spaced above the liquid level in the vertical direction.
    In the exemplary embodiment, the temperature sensor 2 is flush with the outer surface of the housing 9 of the cooking aid device 1, wherein the temperature sensor 2 penetrates the housing 9. This allows the temperature to be reliably measured and a sudden increase in temperature, e.g. due to the touch of the bottom of the cooking vessel 21, are detected quickly. The temperature sensor 2 may conveniently have a housing part with good thermal conduction properties, e.g. a metallic sleeve, with which a sensor element of the temperature sensor 2 is thermally conductively connected. In other embodiments, the temperature sensor 2 could also have a housing part designed as a, preferably metallic, contact piece, on which the sensor element is heat-conductively fixed. But it is also conceivable and possible that the temperature sensor 2 is arranged in the interior of the cooking aid device 1, in which case the housing 9 at least in the region of the temperature sensor 2 has sufficient thermal conductivity and / or a smaller wall thickness. As a result, the temperature of the bottom 29 of the cooking vessel 21 could be detected.
    In another embodiment, the temperature sensor 2 could also protrude beyond the housing 9 of the cooking aid device 1, preferably only slightly. Even then, the cooking aid device 1 is aimed at depositing on a flat surface conveniently by itself in an erect condition. The erection can be limited by the above temperature sensor 2 in a position in which the longitudinal axis 4 of the cooking aid device 1 is still inclined to the vertical. In this case, various such layers can be taken, in which the longitudinal axis 4 is in each case on the mantle of an imaginary cone. It is then considered the totality of these layers as an upright state in the sense of the previous description.
    The sensor element of the temperature sensor 2 may be a well-known analog sensor or a digital sensor. The measurement resolution of the temperature sensor 2 is less than 0.5 ° C., preferably 0.1 ° C., at least in the range below 100 ° C. The temperature sensor 2 has an upwardly limited in the embodiment
    Measuring range of at least 280 ° C on.
    In the exemplary embodiment, the cooking auxiliary device 1 on an energy harvesting device for supplying the electronic circuit 3 with electrical energy. In the illustrated application, the charging coil 7 of the energy harvesting device of the recovery of electrical energy from magnetic stray fields of eddy currents of an induction hob a -Kochstelle 22. This serves when heating a cooking vessel 21 by means of induction coils ------------- ---------- generated eddy currents can be used in addition to the heating of the cooking vessel 21 and to supply the electronic circuitry 3 with electrical energy during operation of the cooking aid device 1. The already mentioned additional weight 6 consists in the embodiment of a ferrite ring. The ferrite ring bundles the eddy currents and increases the efficiency of the charging coil 7 of the energy harvesting device.
    The energy storage element 5 ensures the power supply of the electronic circuit 3 in this case, in particular during breaks in the cooking area 22. For this purpose, the energy storage element 5 as a rechargeable battery or as a capacitor, in particular as a supercapacitor be formed. If it is ensured that the energy harvesting device always provides sufficient energy when temperature measurement and transmission is desired, the energy storage element 5 can also be dispensed with.
    Notwithstanding the illustrated embodiment, it is also possible in a further embodiment of the cooking aid 1, to dispense with an energy harvesting device and provide only an energy storage element 5 for supplying the electronic circuit 3 with electrical energy. In this case, the charging coil 7 shown in the exemplary embodiment could be provided for charging the energy storage element 5 by means of a non-contact charging device. The charge takes place here outside the operating hours of the cooking aid device 1. On the other hand could
    Energy storage element 5 also be a removable and usable by the end user from the cooking aid device 1 battery.
    Based on the erected state in which the auxiliary cooking device 1 rises when resting on the floor 29 by itself, the vertical distance of the electronic circuit assembly 3 from the bottom 29 is at least 1 cm.
    As a result, the semiconductor components of the electronic circuit 3 are from the direct action of the heat of the heated bottom 29 of a cooking vessel 21 -------------------------- ------ protected. Also, the energy storage element 5 is based on the erected state occupies the cooking aid 1 on the ground 29, with a vertical distance of at least 1cm, conveniently more than 2 cm, spaced from the bottom 29. In the exemplary embodiment, the energy storage element 5 is in the erected state of the cooking aid 1 above the electronic circuitry 3 to protect the temperature-sensitive components of the energy storage element 5 from the action of the heat of the bottom 29.
    The electronic circuit 3 and the preferably existing energy storage element 5, and, if present, the charging coil 7 and the additional weight 6, preferably also the temperature sensor 2, are completely arranged in the interior of the housing 9 of the cooking aid device 1. The housing 9 of the cooking aid 1 is preferably shockproof and liquid-tight. At least in a region adjacent to the lowest position in the erected state, the housing 9 is favorably designed for a temperature range of at least 280 ° C.
    The housing 9 of the cooking aid 1 consists of a hygienic and food-grade material, wherein the outer surface of the housing 9 is favorably formed gap-free, to allow quick cleaning.
    The outer surface of the housing 9 is preferably free of depressions, in which otherwise dirt could accumulate.
    In the exemplary embodiment, the communication module 3b is a Bluetooth 4.0 module.
    This is characterized by low power consumption during operation. The use of other wireless communication modules is conceivable.
    In addition to the communication of the communication module 3b with the receiving unit 23, it is also conceivable that the communication module 3b and a data exchange with other electronic devices such. As mobile phones, tablets or other devices for displaying the currently measured temperature or other operating conditions of the cooking aid device allows. In order to increase the range of the communication module 3b, it is conceivable that, based on the self-erected state in which the cooking appliance 1 floating in the water bath assumes, an antenna of the communication module 3b is arranged in the uppermost region of the cooking appliance. This is not shown separately in the figures. Expediently, the communication module 3b also ensures reliable data transmission during operation of the cooking aid device 1 within metallic cooking vessels 21, optionally closed by a lid.
    FIG. 2 shows an example of the regulation of the temperature of a cooking vessel 21 in the form of a frying pan with the aid of the auxiliary cooking device 1. Due to the already explained training of the cooking aid 1 in the manner of a Stehaufmännchens the cooking aid 1 can be placed in any position on the bottom 29 of the cooking vessel 21 and automatically assumes the erected state (= idle state). The cooking vessel 21 is placed on a glass ceramic array 26 of the cooking zone 22 with an induction coil. With the control element 24 can be made by the end user a preselection of the desired temperature (= manipulated variable) of the bottom 29 for the temperature control. The receiving unit 23 of the hotplate 22 receives data, in particular the measured temperature of the bottom 29, from the auxiliary cooking device 1 and supplies it to the heating controller 28, which compares the manipulated variable with the temperature value of the bottom 29 measured by the temperature sensor 2. By the feedback of the actually measured temperature of the water bath by means of the temperature sensor 2 of the cooking aid 1, the control loop is closed. The heating controller 28 controls the heating element 25 (= induction coil) according to the
    Deviation between the desired and the measured temperature of the bottom 29 of the cooking vessel 21 at.
    The term heating controller 28 is to be understood broadly and also includes corresponding driver modules for controlling the respective heating element 25. In the exemplary embodiment, the heating element 25 is an induction coil, with which the bottom of the cooking vessel 21 is inductively heated. As already explained, the stray magnetic field of the eddy currents generated by the induction coil of the - --------------
    Heating element 25 is generated, are used by the cooking aid 1 to recover electricity.
    In addition to the transmission of data on the temperature measured by the temperature sensor 2 of the cooking aid device 1 temperature, it is also conceivable and possible that information about the operating state of the cooking aid device 1, e.g. be transmitted via the charge level of the energy storage element 5 or short-term changes in temperature to the receiving unit 23 or to other electronic devices. When exceeding a predetermined
    Temperature threshold could e.g. a switching off of the heating element 25 and / or the output of a signal, in particular a warning tone, take place.
    Alternatively or additionally, the electronic circuit arrangement 3 of the auxiliary cooking device 1 itself may have a signal device, not shown separately, which generates a warning tone in critical operating states and / or activates a warning light integrated into the electronic circuit arrangement 3.
    Notwithstanding the application shown in Fig. 2, the cooking auxiliary device 1 can also in otherwise formed cooking zones 22, e.g. be used with gas-powered heating elements 25 or heating elements 25 with resistance heating.
    The cooking aid 1 is conveniently further formed as a self-righting float, i. the cooking aid 1 can, if sufficient
    Liquid level, float in liquids. When used in a water bath 20, z. B. in Sous-Vide cooking, the cooking aid device 1 floats in up to 100 ° C hot water bath 20 and can move freely in the water bath 20, see. 3. In particular, no cables or fastening devices lead away from the cooking aid device 1 for attachment in or on the cooking vessel 21 containing the water bath 20.
    The cooking aid 1 floating in the water bath 20 decreases in the -------------------- --------------------- - self-erected state a stable position. At a skew deflected relative to the self-erected state, e.g. when throwing the cooking aid device 1 in the water bath 20 in any position, the cooking aid device 1 is directed by itself in the self-erected state, see. To raise the cooking aid 1 in the self-erected state acts in the tilt of the cooking aid 1 (= shown in broken line position of the cooking aid device of FIG. 3) a righting moment on the cooking aid 1 a , The erection of the auxiliary cooking device 1 from the inclined position is indicated in Fig. 3 by an arrow in the direction of movement 10. In the exemplary embodiment, the additional weight 6 also supports the independent erection of the cooking aid device 1 in the water bath 20.
    In Fig. 3 is shown as an inclined position, a rotation of less than 90 ° about a horizontal axis relative to the self-aligned state. However, the erection also takes place for rotations of more than 90 ° about an arbitrary horizontal axis, preferably also for rotations up to 180 °.
    It is known to self-erect floating objects.
    In particular, in ships such training as self-erector are known.
    In order to train Selbstaufrichter it is particularly important that when deflection of the self-righting (here the cooking auxiliary device 1) from the self-erected state between the weight and the buoyancy force, a lever arm is formed, which causes a righting moment. Such a lever arm can act up to a rotation of up to 180 ° about a horizontal axis to erect the self-erector. With a rotation of exactly 180 ° theoretically a labile equilibrium can be present, which is canceled out at the smallest disturbance, so that the self-erector straightens itself into the self-erected state.
    The temperature sensor 2 of the cooking aid 1 is, based on the ..... self-erect state that floating in the water 20- ------------
    Cooking aid 1 assumes, arranged under the waterline 8 of the cooking aid 1. The waterline 8 lies in a plane with the water level 27, at the point where the water level 27 touches the outer surface of the cooking aid device 1. The position of the water level 27 for cooking auxiliary device 1 in the floating state of the cooking aid device 1 and the water line 8 are shown in Fig. 1.
    If the water level 27 drops during operation so far that the temperature sensor 2 touches the generally much hotter bottom of the cooking vessel 21, a rapid increase in temperature could be detected and an alarm signal sent to the receiving unit 23.
    The electronic circuit 3 and the energy storage element 5 are located in the self-erected state of the floating in the water 20 cooking aid 1 completely above the waterline 8 of the cooking aid 1. The vertical distance of the electronic circuit 3 from the waterline 8 is more than 1 cm. As a result, temperature-sensitive components, in particular semiconductor components, of the electronic circuit arrangement 3 and / or temperature-sensitive energy storage elements 5 are protected from the action of the heat of the water bath 20.
    The cooking auxiliary device 1 is preferably also suitable for detecting the temperature of a heatable from the cooking zone 22 oil bath, in which the
    Cooking aid 1 floats. The temperature of the oil bath filled with edible oil can be up to 180 ° C. Especially when used in an oil bath, it is favorable if the electronic circuit arrangement 3, and preferably also the energy storage element 5, in the self-erected state of the floating in the oil bath cooking appliance 1 is completely above the line in which the oil level touches the outer surface of the cooking aid device 1 , Since edible oil usually has a lower density than water, the dip
    Cooking aid 1 deeper in the oil bath. The distance of the electronic -------------------
    Circuit arrangement 3 from the line in which the oil level touches the outer surface of the cooking aid 1, but is also more than 1 cm in the oil bath, in order to protect the temperature-sensitive components of the cooking aid 1 from the action of the heat of the oil bath.
    The cooking auxiliary device 1 could have a sealed switch for activating the temperature measurement. It is also conceivable that the electronic circuit arrangement has an acceleration sensor. By detecting an applied by the end user movement of the cooking aid device 1 or shaking the cooking aid device 1 activation of the cooking aid device 1 could take place. In another embodiment, the activation by means of a counterpart, z. B. a magnetic switch, done.
    If a charging device is used to charge the energy storage element 5, an automatic activation of the cooking aid device 1 could also take place, for example, during removal from the charger.
    It is conceivable and possible for the auxiliary cooking device 1 to have an indicator which constitutes a "misuse" (eg when using the auxiliary cooking device at temperatures above the permissible operating temperature) a "predetermined breaking point." This may result in an unjustified claim on the manufacturer's warranty be detected in an improper use of the cooking aid device 1. Such "predetermined breaking points" in the sense of a defined security feature to detect overuse of the cooking aid device 1 are known in other areas.
    The cooking auxiliary device 1 holds conveniently acting magnetic fields of an induction hob when unintentionally placing the cooking aid device 1 on an induction hob stood.
    In the simultaneous use of several auxiliary cooking devices 1 with several different cooking vessels 21, it is conceivable and possible that a unique
    Assignment of the respective cooking auxiliary device 1 to the respective receiving unit 23 ---------- and / or to the respective heating controller 28 takes place. As a result, the temperature of the bottom 29 of the respective cooking vessel 21 or of the water bath 20 to be regulated can be supplied to the respectively associated control circuit. To the assignment or
    To facilitate pairing, it is conceivable that the optional signal unit of the cooking aid device 1 generates an optical, acoustic or haptic feedback in the assignment of the cooking aid device 1 to the respective control loop.
    In the exemplary embodiment, the temperature sensor 2 is based on the erected state of the cooking aid device 1 in the region of the lowest point of the cooking aid device 1 and touches the bottom 29 of the cooking vessel 21. This need not be so. If the cooking auxiliary device 1, for example, only used for baking food with a floor covered with an oil layer, it is conceivable and possible that the temperature sensor relative to the erected state of the cooking aid at a defined location spaced from the ground, e.g. laterally, is arranged on the cooking aid.
