DESCRIPTION OF THE INVENTION

[0091] In the following, similar reference signs are used for similar elements.

[0092] FIG. 1 shows a schematic view of an embodiment of an accessory 100 for a (not shown) kitchen appliance. The kitchen appliance is in particular a food processor configured to prepare food at least partially automatedly. As will be described in more detail, the kitchen appliance comprises a reading arrangement with a reading controller and at least one reading antenna connectable to the reading controller.

[0093] The accessory 100 is, for example, a varoma, stirring attachment, knife cover, measuring cup, lid, cooking basket or the like. The accessory 100 is directly or indirectly couplable to the kitchen appliance.

[0094] In particular, in order to be able to detect a correct positioning of the accessory 100 on respectively with respect to the kitchen appliance, that is, in particular, in order to be able to detect the operating position of the accessory 100, the accessory 100 comprises, according to the application, a transponder arrangement 102.

[0095] In particular, the transponder arrangement 102 is readable by the reading antenna at least in the operating position of the accessory 100. The transponder arrangement 102 comprises a transponder 104 and an accessory position sensor 108 coupled to the transponder 104. The accessory position sensor 108 is preferably an acceleration sensor 108. The accessory position sensor 108 is configured to detect at least one accessory position parameter (e.g., vertical axis angle, lateral axis angle, and/or longitudinal axis angle) of the accessory 100. Preferably, the accessory position sensor 108 may be configured to detect the angle of inclination of the accessory 100 with respect to the acceleration due to gravity.

[0096] The transponder 104 is preferably an RFID transponder 104. In particular, the accessory position sensor 108 may provide the transponder 104 with the (instantaneously) detected accessory position parameter and accessory position parameter value, respectively. For example, in the case of a passive transponder 104, the accessory position sensor 108 may be activated by the transponder 104 by providing power to the accessory position sensor 108 based on the received reading field of the reading antenna. Thereupon, the accessory position sensor 108 may provide the transponder 104 with the (instantaneously) detected accessory position parameter and accessory position parameter value, respectively. This is then transmitted by the transponder 104 to the reading arrangement. In particular, the transponder 104 may encode respectively manipulate the reading field according to the at least one (instantaneously) detected accessory position parameter. This can be decoded by the reading controller (in particular an RFID reader).

[0097] Optionally, the transponder 104 may comprise at least one readable memory 101. As has been described, the memory 101 may store at least one of an accessory identifier (such as a serial number or a Universally Unique Identifier (UUID)) and/or origin information (such as manufacturer identity, time of manufacture, place of manufacture, and/or authentication information) and/or an accessory type identifier and/or calibration information of the accessory position sensor 108. This could be stored prior to distribution, during or at the end of manufacturing, or during a dedicated calibration step. Corresponding data can be read in particular by the reading arrangement in addition to the (instantaneously) detected accessory position parameter.

[0098] FIG. 2 shows a schematic view of an embodiment of a kitchen appliance 230 according to the present application. The kitchen appliance 230 comprises an appliance base 232, a pot 216, and a lid 200 as an accessory according to the application. It shall be understood that the pot is also an accessory and in variants of the application the pot may have a transponder arrangement according to the application.

[0099] In particular, the pot 216 and the lid 200 may form a container arrangement of the kitchen appliance 230. The pot 216 comprises a circumferential pot wall and a pot base.

[0100] The lid 200 is configured to close an opening of the pot 216. This closed state of the container arrangement is shown in FIG. 2. In particular, the lid 200 is in the locked position in FIG. 2. In particular, this means that the lid 200 is (correctly) mechanically locked to the pot 216, i.e. the container arrangement is in the locked state. In the present case, this is synonymous with the fact that the accessory 200 is in the operating position, i.e. in particular is positioned and arranged, respectively, ready for operation on the kitchen appliance 230.

[0101] In particular, the lid 200 is movable relative to the pot 216 between an unlocked position and a (defined) locked position. The locking mechanism may be, for example, a bayonet latch or similar mechanical latch.

[0102] The illustrated kitchen appliance 230 comprises an appliance base 232 having a pot receptacle 234. The pot receptacle 234 is configured to receive the pot 216, in particular at least the bottom of the pot. As can be seen, the pot receptacle 234 corresponds to the pot 216 of the container arrangement such that an electrical connection is established between a first lower electrical pot contact 220 and a first electrical base contact 236 of the appliance base 232, and an electrical connection is established between a second lower electrical pot contact 222 and a second electrical base contact 238 of the appliance base 232 when the pot 216 is (correctly) arranged in the pot receptacle 232.

[0103] The kitchen appliance 230 comprises a reading arrangement 221. The reading arrangement 221 comprises a reading controller 226, in particular an RFID reader, and a reading antenna 206, in particular an antenna coil. In the present embodiment, the reading controller 226 is connected to the first base contact 236 and the second base contact 238 via an optional filtering and matching network 240. In the present embodiment, the reading antenna 206 is connected to the first lower pot contact 220 and the second lower pot contact 222.

[0104] When the pot, 216, as shown, is arranged in the pot receptacle 234, the reading controller 226 may apply an antenna signal to the reading antenna 206 such that the reading antenna 206 emits a reading field.

[0105] The accessory 200 in the form of the lid 200 comprises a transponder arrangement 202. The transponder arrangement 202 can in particular be formed in the same way as the transponder arrangement according to FIG. 1 so that reference is made to the explanations regarding FIG. 1 in order to avoid repetitions.

[0106] In particular, the reading arrangement 221 is configured to read the transponder arrangement 202.

[0107] FIG. 3 shows a schematic view of a further embodiment of a kitchen appliance 330 according to the present application. Tin order to avoid repetitions, essentially only the differences to the previous embodiments are described below and otherwise reference is made to the previous embodiments. In particular, the illustration of an accessory has been omitted in favor of a better overview.

[0108] The reading controller 326 of the reading arrangement 321 comprises an evaluation module 370 and a kitchen appliance position sensor 372. The kitchen appliance position sensor 372 may be configured to detect a kitchen appliance position parameter. Preferably, the kitchen appliance position sensor 372 may be an acceleration sensor, in particular a 3-axis acceleration sensor. In particular, the axes may be the transverse axis, longitudinal axis, and vertical axis. Preferably, the at least one accessory position parameter may be an (instantaneous) angle of inclination of the kitchen appliance 330 (in particular the appliance base 332) with respect to the acceleration due to gravity. For example, the angle of inclination of the kitchen appliance 330 (in particular the appliance base 332) with respect to the acceleration due to gravity may be determined from a detected transverse axis angle, longitudinal axis angle, and/or vertical axis angle.

[0109] The evaluation module 370 may be configured to determine whether the accessory comprising the transponder arrangement is properly positioned and arranged, respectively, on the kitchen appliance 330. For this purpose, at least one accessory position parameter may be read from the transponder arrangement and, in particular, the at least one read accessory position parameter may be evaluated.

[0110] Preferably, the evaluation module 370 may compare the at least one read accessory position parameter (for example, an aforementioned angle, in particular an angle of inclination with respect to the acceleration due to gravity) with the operating position criterion. The operating position criterion may define when proper positioning is (or is not) present. For example, the operating position criterion may define a corresponding angular range. In particular, the angular range may be based on the at least one kitchen appliance position parameter (e.g., said angle of inclination). For example, the angular range may be a tolerance range lying around the instantaneous angle of inclination.

[0111] If the read angle (value) is within the angle range, the evaluation module 370 may determine that the accessory is properly positioned and arranged, respectively, on the kitchen appliance 330. If the read angle (value) is not within the angle range, the evaluation module 370 may determine that the accessory is not properly positioned and arranged, respectively, on the kitchen appliance 330.

[0112] As has already been described, the evaluation module 370 may additionally take into account further read data in the evaluation, such as an accessory identifier (such as a serial number or a Universally Unique Identifier (UUID)) and/or origin information (such as manufacturer identity, date of manufacture, place of manufacture, and/or authentication information) and/or an accessory type identifier and/or calibration information of the accessory and/or calibration information of the kitchen appliance 330, in particular the appliance base 332.

[0113] FIG. 4a shows a schematic side view of an embodiment of a pot 416 of a kitchen appliance according to the present application, and FIG. 4c shows a schematic top view of an embodiment of a lid 400 of the kitchen appliance structurally corresponding to the pot 416 according to the present application. FIG. 4b shows an enlarged section, in particular a top view, of the pot 416 according to FIG. 4a.

[0114] The pot 416 is preferably formed partially of metal and partially of plastic. In particular, a section 442 may be formed of plastic. This section 442 may also form the handle and may in particular comprise an at least partially, preferably completely, annular sub-section 443 arranged on the pot edge 403.

[0115] In the present embodiment, a first upper electrical pot contact 412 is arranged at the upper pot edge 403. Preferably, a second upper electrical pot contact (not shown) is arranged on the opposite side of the upper pot edge 403.

[0116] The first electrical pot connection 418 extends from the first upper electrical pot contact 412 in particular through the section 442 to the first lower pot contact 420. In particular, the first pot connection 418 may be integrated in the plastic section 442. In particular, the first lower pot contact 420 is arranged in respectively at the bottom of the pot. The further (not shown) pot connection may be formed accordingly.

[0117] The upper first pot contact 412 and the second pot contact are preferably embedded in the annular plastic subsection 443. This subsection 443 preferably comprises a portion of the locking mechanism of the container arrangement. In particular, the subsection 443 may comprise contours for locking the lid 400 to the pot 416 in the defined locking position.

[0118] As can be seen from the top view of the associated lid 400 in FIG. 4c, a first lid contact 411 and a second lid contact 413 are arranged on the lid 400, in particular on the outer lid edge 405.

[0119] In particular, the reading antenna 406 of the reading arrangement 421 of the kitchen appliance is an antenna coil 406. In particular, the antenna coil 406 may be formed by at least one winding 409, preferably a plurality of windings 409, as shown. In particular, the at least one winding 409 may be formed of a metal, preferably copper.

[0120] As can be seen from FIG. 4c, the at least one winding 409 extends in particular along the lid edge 405 respectively in the vicinity of the lid edge 405 from the first lid contact 411 to the second lid contact 413. The second lid contact 413 is located in particular on a side of the lid edge 405 opposite to the first lid contact 411.

[0121] The at least one winding 409 is preferably inserted into the lid base body during manufacturing and subsequently provided with a (not shown) cover (preferably formed of plastic), which can be attached to the lid base body, for example, by ultrasonic welding.

[0122] Preferably, the first lid contact 411 and the second lid contact 413 may be arranged on the lid 40 and relative to the upper pot contacts 412 such that an electrical connection between the first lid contact 411 and the first upper pot contact 412 and an electrical connection between the second lid contact 410 and the second upper pot contact are established only when the lid 400 is in the locked position. In other words, an antenna signal can only be applied to the reading antenna 406 by the reading controller system when the lid 400 is in the locked position. Only in the locked position the circuit is closed.

[0123] In the present embodiment, the respective connections between the lid contact and pot contact are contact-based connections.

[0124] In the present embodiment, the lid contacts 411, 413 and the upper pot contacts 412 are formed as exposed electrical contacts 411, 412, 413. Preferably, the lid contacts 411, 413 comprise a first longitudinal extension in a first direction and the respective associated upper pot contact 412 comprises a second longitudinal extension in a second direction. As can be seen, there is an angle of between 10° and 90° between the first and the second direction (which are located in particular in the same plane), in particular of approximately 90° in the present case.

[0125] When the lid 400 is moved from the unlocked position to the locked position (which can take place, for example, in the form of a rotary movement), the respective contacts 411, 412, 413 slide on each other or along one another in a contact-based manner. This can prevent impairment of the contact resistance at the respective contacts 411, 412, 413 since any impurities adhering to the contacts 411, 412, 413 are scraped off.

[0126] In addition, a back lining 444 with a resilient material (e.g., silicone) may be provided at the lid contact 411, 413 or pot contact 412.

[0127] Preferably, as an accessory the lid 400 further comprises a transponder arrangement 402. In other words, in a preferred embodiment, the transponder arrangement 402 and the reading antenna 406 of the reading arrangement 421 may be arranged in an accessory.

[0128] The transponder 404 is arranged within the range of the antenna coil 406. In particular, the transponder 408 is surrounded by the at least one winding 409. In one embodiment, there may be 3 or 4 windings.

[0129] The transponder associated with a pre-described accessory position sensor 408 comprises a second antenna coil 425. For example, the transponder arrangement 402 may be adhered. The transponder arrangement 402, in particular the antenna coil 425, may be covered by a not shown cover, for example made of plastic.

[0130] Instead of a respective electrical connection in contact-based manner, in general a contactless electrical connection can also be provided between a lid contact and a pot contact in each case.

[0131] The first lid contact may be formed as a first lid surface element (e.g., by a foil of an electrically conductive material, such as a metal foil) and the second lid contact may be formed as a second lid surface element (e.g., by a foil of an electrically conductive material, such as a metal foil).

[0132] The first upper pot contact may be formed as a first pot surface element (e.g., by a foil of an electrically conductive material, such as a metal foil), and the second upper pot contact (e.g., by a foil of an electrically conductive material, such as a metal foil) may be formed as a second pot surface element.

[0133] In a locked position of the lid, the first lid surface element and the first pot surface element may form a first coupling capacitor. The second lid surface element and the second pot surface element may form a second coupling capacitor.

[0134] In particular, said surface elements form a respective coupling capacitor only in the locked position of the lid. In other words, only in the locked position can the antenna signal provided by the reading controller be transmitted to the reading antenna (e.g., a (schematically indicated) antenna coil) via said coupling capacitors.

[0135] The dielectric of the respective coupling capacitor is defined in particular by air and/or the used plastic.

[0136] Finally, it should be noted that reference sign 450 denotes the vertical axis of accessory 400, reference sign 452 denotes the longitudinal axis of accessory 400, and reference sign 454 denotes the transverse axis of accessory 400.

[0137] FIG. 5a shows a schematic view of an embodiment of an accessory 500.1 according to the present application in an operating position and FIG. 5b (in comparison to FIG. 5a) shows a schematic view of an embodiment of the accessory 500.1 in a non-operating position. In order to avoid repetitions, essentially only the differences from the previous embodiments are described below, and otherwise reference is made to the previous explanations. In particular, details (e.g. transponder arrangement) have been omitted in favor of a better overview.

[0138] As can be seen from FIG. 5a, the accessory 500.1 is operatively coupled to the kitchen appliance 530. Presently, the accessory 500.1 is coupled and connected, respectively, to the lid 500.2 of the kitchen appliance 530. In other words, the accessory 500.1 is in the operational position.

[0139] For example, pot 516 and lid 500.2 may be formed according to the pot and lid of FIG. 4.

[0140] In this case, the evaluation module of a reading arrangement will determine that, for example, the detected angle of inclination with respect to the acceleration due to gravity of the accessory 500.1 satisfies the operating position criterion. For example, the operating position criterion may be a detected angle of inclination with respect to the acceleration due to gravity of the kitchen appliance 530 (or a tolerance range around that angle of inclination). In particular, the operating position criterion is satisfied if the angle of inclination with respect to the acceleration due to gravity of the accessory 500.1 substantially corresponds to the angle of inclination with respect to the acceleration due to gravity of the kitchen appliance 500.1, i.e., in particular, lies within the angle range and tolerance range, respectively. This means in particular that the angle of inclination between the two sensors (within a tolerance range) becomes equal to zero.

[0141] In addition, an accessory type criterion and, if necessary, calibration information can be taken into account. In particular, at least one of the angles of inclination can be corrected and adjusted, respectively, by means of the accessory type criterion and/or calibration information.

[0142] In particular, the evaluation module can therefore determine the operating position of the accessory 500.1 based on the read accessory position parameter and an operating position criterion.

[0143] As can be seen from FIG. 5b, the accessory 500.1 is not properly respectively operably positioned on the kitchen appliance 530. Rather, the accessory 500.1 lies in the edge region of the lid 500.2 and thus, due to the undertaken design and/or structural measures, lies in an inclined manner on the accessory 500.1 and/or the further accessory 500.2. Thus, the accessory 500.1 is not coupled and positioned, respectively, correctly with the lid 500.2 of the kitchen appliance 530. In other words, the accessory 500.1 is in a non-operating position. In particular, proper operation is not possible in this position.

[0144] In this case, the evaluation module of a reading arrangement will determine that, for example, the detected angle of inclination with respect to the acceleration due to gravity of the accessory 500.1 does not satisfy the operating position criterion. For example, the operating position criterion may be a detected angle of inclination with respect to the acceleration due to gravity of the kitchen appliance 530 (or a tolerance range around this angle of inclination).

[0145] In particular, the operating position criterion is not met if the angle of inclination with respect to the acceleration due to gravity of the accessory 500.1 does not substantially correspond to the angle of inclination with respect to the acceleration due to gravity of the kitchen appliance 500.1, i.e., in particular, if it lies outside the angle range and tolerance range, respectively.

[0146] In addition, an accessory type criterion and, if necessary, calibration information can be taken into account. In particular, at least one of the angles of inclination can be corrected and adjusted, respectively, by means of the accessory type criterion and/or calibration information.

[0147] In particular, therefore, the evaluation module can determine the non-operating position of the accessory 500.1 based on the read accessory position parameter and an operating position criterion.

[0148] FIG. 6 shows a schematic view of a further embodiment of a kitchen appliance 630 according to the present application. In order to avoid repetitions, essentially only the differences to the previous embodiments are described below, and otherwise reference is made to the previous embodiments.

[0149] As can be seen, the appliance base 632 comprises a tool drive 660. The tool drive 660 is configured to drive respectively operate an (accessory in the form of) a kitchen appliance tool 662, which may in particular be located in the pot 616. Exemplarily, a kitchen appliance tool 662 is shown as a cutting tool 662. Further, the kitchen base may comprise a control device that controls and monitors the heater that is integrated in the pot 602.

[0150] An accessory 600.1 in the form of a stirring attachment 600.1 is positioned on respectively at the kitchen appliance tool 662. As shown, the accessory 600.1 is correctly positioned respectively presently coupled to the kitchen appliance tool 662 (and thus to the kitchen appliance 630). In particular, the shown accessory 600.1 is in an operating position.

[0151] As can be seen, the kitchen appliance 630 comprises a further accessory 600.2 in the form of a lid 600.2. Pot 616 and lid 600.2 may be formed, for example, according to the pot and lid of FIGS. 4a and 4b.

[0152] In particular, the reading controller 626 comprises an evaluation module 670 and a kitchen appliance position sensor 672. In particular, the evaluation module 670 is configured to detect respectively determine the operating position respectively an operating state of the accessories 600.1, 600.2 based on the data (at least the respective currently detected accessory position parameters) read from the transponder arrangements 602.1, 602.2 in each case.

[0153] For example, the lid 600.2 may be moved to the locked position by a user. Once the lid 600.2 is in the locked position, an electrical connection is established between the first lid contact 611 and the first upper pot contact 612, and an electrical connection is established between the second lid contact 613 and the second upper pot contact 614. An antenna signal is applied to the reading antenna 606 by the reading controller 626 via the established connections such that in particular a reading field is generated and transmitted.

[0154] The transponders 604.1, 604.2 arranged within range receive the reading field and in particular extract the instructions contained therein. Based on the instructions, the respective transponder 604.1, 604.2 generates a response. For example, the respective transponder 604.1, 604.2 outputs the respective instantaneously detected accessory position parameters and optionally the respective stored data, such as an accessory identifier and/or an origin information and/or an accessory type identifier and/or a calibration information of the respective accessory position sensor 608.1, 608.2. In particular, the respective transponder 604.1, 604.2 influences the reading field accordingly. This can be detected by the reading controller 626 so that said data is read.

[0155] In the manner described above, an operating position or a non-operating position of the accessories 600.1, 600.2 can be determined.

[0156] Furthermore, the appliance base 632 comprises a releasing module 674. The releasing module 674 is in particular configured to release at least one device function in particular depending on the accessory type of the at least one accessory 600.1, 600.2 (properly) positioned at the appliance base 632 and/or at a further accessory. The releasing module 674 can in particular be communicatively connected to the evaluation module 670. If no properly positioned accessory is detected, the at least one device function may remain disabled.

[0157] Preferably, the evaluation module 670 may additionally be configured to determine the accessory type based on the read data, in particular the accessory type identifier and a stored accessory type criterion. Preferably, the accessory type criterion may be an assignment table described above. In particular, the assignment table can additionally store for each accessory type the at least one device function permitted for this accessory type.

[0158] Exemplary and non-exhaustive kitchen appliance functions respectively device functions are: A first cutting function with a first maximum permissible set speed and/or set torque, a further cutting function with a second (different from the first maximum permissible set speed and/or set torque) maximum permissible set speed and/or set torque, a first stirring function with a first maximum permissible set speed and/or set torque, a further stirring function with a second (different from the first maximum permissible set speed and/or set torque) maximum permissible set speed and/or set torque, a first motor direction of rotation, a second opposite motor direction of rotation, a first set temperature (or heating power) and/or a second set temperature (or heating power) and/or a second set temperature (or heating power). a first set temperature range (or heating power range) of a heater integrated in the food receptable element, a second set temperature (differing from the first set temperature) and/or a second set temperature range (differing from the first set temperature range) of a heater integrated in the food receptable element, control programs and/or control program set parameters for specific operations, etc.

[0159] In particular, after determining the accessory type of the at least one arranged accessory 600.1, 600.2, the at least one device function permitted for this accessory type can be released by the releasing module 674. The accessory type and optionally the permissible device function can be determined in particular by comparing the read accessory type identifier with the accessory type identifiers stored in the assignment table.

[0160] If the allowable device function comprises a maximum allowable drive set parameter value, a releasing of a device function may comprise, in particular, limiting, for example by the releasing module 674, the operation of the tool drive 660 to the drive set parameter value stored for that accessory type (e.g., a maximum allowable set speed and/or torque).

[0161] Optionally, the kitchen device 630 may have a (visual) screen 666, such as a display. The display 666 may be configured to display the identified accessory type. Optionally, an error message (for example, if an operating position and coupling condition, respectively, was detected but no accessory type could be determined, or if a non-operating position and non-coupling condition, respectively, was detected) and/or an advisory message (for example, a request for cleaning) may be displayed.

[0162] The operation of a kitchen appliance, such as the kitchen appliance 630, is described in more detail below with the aid of FIG. 7. FIG. 7 shows a diagram of an embodiment of a method according to the present application. The method is used to detect respectively determine the operating position of an accessory.

[0163] In a step 701, a reading is performed, by a reading arrangement of the kitchen appliance, of the accessory position parameter of the accessory detected by the accessory position sensor, as has already been described.

[0164] In a further step 702, a determining is performed, by an evaluation module of the reading arrangement, of an operating position of the accessory based on the read accessory position parameter and an operating position criterion.
