Description

[0001] This invention relates to a food processing machine and a method for preparing food using the food processing machine.

[0002] Food processors known in the prior art include a base component and a food preparation container that can be mechanically and electrically coupled to the base component. Patent publication EP 2 698 088 B1 discloses an electrically operated food processor in which a lid of a cooking container is locked from above using two rollers, which, when in the closed position, form-fit to prevent the lid from being removed upwards.

[0003] The objective of this invention is to provide a further developed food processing machine and associated method for food preparation.

[0004] This task is accomplished by the food processor according to claim 1 and the method according to the appended claim. Advantageous embodiments are specified in the dependent claims.

[0005] A food processor including a base component is provided to address this problem. The base component preferably includes an interface for mechanical and / or electrical coupling with an attachment. Specifically, the food processor (e.g., the base component) is configured to identify (detect / identify) the type of the attachment. Specifically, the food processor (e.g., the base component) is configured to influence the function of the interface based on the identified attachment type. This is particularly useful for operating attachments used in food preparation.

[0006] This invention allows for flexible use of the interface of the base component, and its use depends on the identified attachments. Depending on the identified attachments, the behavior of the interface can be automatically adjusted to prepare food. Each attachment can automatically perform its corresponding required function. This eliminates the possibility of misoperation. Furthermore, additional attachments that require the use of other functions of the interface can be easily installed and used. This makes it easy to expand the scope of functionality.

[0007] A food processor may include a base component and an attachment connectable to the base component. Typically, the base component holds and / or carries the attachment, and / or is used for control. The base component is generally adapted to be placed on a surface. In particular, the base component has output and / or input devices. The base component typically includes a motor for driving a rotatable tool or a tool holder for driving a tool in the attachment. When connected, the base component may supply electrical power to the attachment to rotate the tool of the attachment, and / or transmit data to and / or receive data from the attachment. The base component may preferably supply electrical power to functional components of the attachment.

[0008] The attachment can be, for example, a food preparation container, such as a cookware, saucepan, steamer, pressure cooker (steam pot), chopping device, popcorn machine, deep fryer, or mixing bowl. The attachment can be a food preparation container that combines several of the aforementioned functions. A food preparation container is a container capable of holding food or food ingredients to perform preparation steps. Within the meaning of this invention, food also includes individual ingredients. Preparation steps may include, for example, heating, stirring, chopping, and / or settling. The food preparation container can be a single piece or multiple pieces. Various attachments may exist, differing in, for example, height, diameter, type, supported functions, and the number of functional components.

[0009] The attachment may have one or more functional components, such as a tool for food preparation, which is particularly rotatable, such as a stirring tool, kneading tool, mixing knife, or cutting and / or grating disc. The tool can be used to stir and / or chop food. The actuation of the tool is discussed in detail below. In one embodiment, the tool may be mounted on a tool holder that is connected to the attachment.

[0010] Alternatively or additionally, the attachment may include a heating device as a functional component for heating the attachment and / or food located therein. One, two, or more heating devices may be present, and they may be controlled together and / or individually. For example, thick-film heaters, tubular heaters, and / or flat-plate heaters may be present. The attachment may also include one or more sensors, such as temperature sensors, pressure sensors, and / or sensors for identifying the type of functional module. The attachment may also have a wired or wireless interface for sending and / or receiving data.

[0011] Any attachment with any combination of functional components is possible. An attachment could be a food preparation container with only one or more temperature sensors. Multiple temperature sensors allow for more precise and / or higher spatial resolution temperature determination. In this case, the food preparation container does not have a heating element or a rotating tool. Such a food preparation container could be used, for example, for dough proofing. Another attachment could be a saucepan with a heating element but no rotating tool. Yet another attachment could be a mixing container designed only for low-speed operation.

[0012] An interface is used to mechanically and / or electrically couple an attachment to a base component. Specifically, mechanical coupling refers to direct mechanical coupling, where the attachment and the base component are in contact. For mechanical coupling, the interface is particularly a physical interface. In this way, the attachment can be supported or held by the base component. Coupling preferably means positioning the attachment in or on the interface such that the attachment can operate together with the base component for food preparation. Typically, at least a majority of the attachment is located above at least a majority of the base component. Thus, the attachment is placed on (above) the base component. The attachment may have a corresponding interface that can be coupled to the interface of the base component.

[0013] The interface can be virtually any shape, for example, a flat surface. The interface may advantageously include a socket for inserting an attachment. The attachment can be inserted into the socket for operation there. The socket may be designed as a recess or have one or more recesses into which the attachment, or its various parts, can be inserted. In this case, at least one segment of the attachment moves below at least one segment of the base member during placement. Preferably, the interface is configured such that at least lateral movement of the attachment relative to the base member is blocked, particularly by a rigid connection. This prevents the attachment from slipping. If the attachment is not locked to the base member, it can typically be removed from the base member by upward movement of the attachment. Typically, the interface is configured to couple different attachments to the base member.

[0014] This interface can also be used to control the attachment and / or its functional components for food preparation. The interface can have different functions to control different areas of the attachment, and can also have functional modules if needed.

[0015] The food processor is configured to identify the type of attachment. The control unit of the food processor can be configured to receive information about the type of attachment.

[0016] Identifying attachment type or category may include categorizing the attachment into a specific product category. For example, it may identify whether the attachment is a cookware, frying pan, or mixing bowl. It may also identify whether the attachment is a small-capacity or large-capacity cookware. In particular, type identification includes identifying predefined product models. This allows for understanding certain characteristics of the product, such as the functional components provided by the cookware, the food preparation processes that can be performed with the cookware, and / or the characteristics of the cookware, such as the maximum temperature at which the cookware can be heated, the maximum rotation speed of the attached tool, or the maximum pressure within the cookware. In one configuration, each individual attachment may be identified by a unique identifier.

[0017] The food processor affects the function of the interface to operate the attachment for food preparation. For example, the food processor (particularly the control unit) causes the operating parts or shafts to rotate, or activates one or more electrical contacts to transmit data and / or energy. In this way, the functional components of the attachment can be operated for food preparation.

[0018] This food processor automatically adjusts its interface in response to the type of attachment identified. Specifically, no user intervention is required. For example, the food processor can recognize a container with a knife-shaped tool coupled to the base component, on which a lid is placed and locked. In this case, the food processor allows the shaft to rotate at high speed, for example, to chop solid food. On the other hand, if a pan without a rotating tool is identified coupled to the base component, the motor used to rotate the shaft is de-energized.

[0019] Specifically, the food processor is configured to check for the presence of attachments and, if necessary, influence the function of the interface based on the results of the check. The food processor can be configured to perform this check during startup or each startup. For example, rotation of the shaft can be stopped as long as no attachments are coupled or no attachments with rotating tools are coupled. Typically, the system first checks for the presence of attachments, and if present, identifies the type of attachment.

[0020] In one configuration, the interface further includes a rotatable shaft for driving a rotatable tool of the attachment. Specifically, the base component includes a motor for rotating the shaft. The shaft typically has a non-circular profile, particularly on the upper side, which is rotatably fixed to a corresponding profile on the attachment. The attachment may have a connecting shaft to transmit rotation of the base component's shaft to the tool. This connecting shaft may also have a non-circular profile, particularly on the lower side of the attachment, which is rotatably fixed to a corresponding profile of the shaft on the base component.

[0021] This shaft can function as an interface, and its operation can be adjusted based on the type of attachment identified. For example, it can identify cookware without a lid and / or designed only for low-speed operation. In this case, the food processor can control the interface so that the rotational speed of the rotatable shaft does not exceed a predefined maximum rotational speed.

[0022] In one embodiment, the interface includes a rotatable actuating component for performing functions (particularly on the attachment). Functions may include performing, operating, controlling, or triggering functions, such as functional components of the attachment or functional modules connected thereto. One possible function of the attachment may be, for example, locking the attachment to a base component, particularly in a form-fitting manner. When locked, the attachment cannot be removed from the base component. Furthermore, functions of the attachment may be triggered, such as opening or closing a valve on the attachment. Another possible function may include moving a movable portion of the attachment, such as a transmission mechanism. The transmission mechanism may in turn perform functions, such as locking a functional module to the attachment, or controlling the function of the functional module, such as opening or closing a valve on the functional module, or operating a switch or button. Functions may also include moving a locking element to enable or disable movement of another component. In principle, rotational movement of the actuating component can be directly used to perform a function, and / or for this purpose can be one or more transitions to another movement, which may be, for example, linear movement or rotational movement about another axis of rotation.

[0023] In principle, the function can also include rotating the attached component (e.g., a rotatable tool) in the attachment, for example, by subjecting it to oscillating motion or by gradually rotating it in a rotational direction. This can be accomplished independently of the driven shaft used to drive the base component of the rotatable tool.

[0024] In one embodiment, the base component includes an actuator for driving the operating component. This actuator is particularly electrically operated and may be designed as an electric motor, such as a servo motor. The actuator is particularly positioned below the socket and / or attachment. The actuator is used to rotate the operating component, thereby automatically performing one or more of the described functions.

[0025] Specifically, the food processor is configured to control actuators based on the type of identified attachment to influence the position or movement of the operating component. In other words, the actuator and / or the driver of the operating component are functions of the interface that can be influenced or controlled. This allows the position of the operating component to be adjusted according to the type of attachment. For example, the attachment may be identified as a food preparation container lockable to a base component, and rotating it from an initial position in a specific direction by a specific angle locks the food preparation container to the base component. When locking is desired or required, the actuator can be controlled to cause the operating component to perform the described rotation.

[0026] In one configuration, the food processor includes a control device configured to control an actuator. The control device can control the position and / or movement of the operating component depending on the type of attachment. Specifically, the control device is configured to move the operating component to a specific rotational position.

[0027] In one embodiment, the operating member has at least one contact element. This contact element can be used to rigidly lock the attachment to the base member. Specifically, the contact element contacts a corresponding element of the attachment. In particular, this prevents the attachment from being lifted in the axial and / or vertical directions in a form-fitting manner when locked. In supplementary or alternative configurations, the contact element is used to transmit rotational movement and / or force of the operating member to the attachment. Specifically, the attachment has a corresponding element that contacts the contact element of the operating member, and moves and / or is acted upon by the force of that contact element.

[0028] Specifically, the contact elements protrude radially from adjacent structures of the operating component, for example, outwards. In particular, there are multiple (e.g., three) contact elements that may be distributed around a circumference.

[0029] The operating component is capable of rotating about an axis of rotation. In one configuration, the operating component can rotate about an axis that is at least substantially vertical, and / or about an axis of rotation aligned with the axis of rotation used to drive the food preparation tool. This allows for parallel alignment of the axis of rotation in a particularly advantageous manner. For example, this allows for locking the attachment from below. Particularly preferably, the operating component and the axis have the same axis of rotation. In one configuration, the operating component is annular, e.g., circular, which is generally relative to the axis of rotation. In other words, the radial interior of the operating component is empty. This allows the base component or one or more other components of the food processor, such as the axis for driving the tool used for food preparation, to be accommodated there.

[0030] In one embodiment, the interface includes a plurality of electrical contacts for transmitting data and / or electrical power between the base component and the attachment. Specifically, the electrical contacts are used to provide a conductive connection with the attachment. Specifically, the attachment includes at least one, and typically several, corresponding electrical contacts. These electrical contacts are a function of the interface that may be affected depending on the type of attachment identified.

[0031] Electrical energy includes voltage and current. A drive mechanism can be used to transfer data and / or current from a base component to an attachment. A drive mechanism can also be used to receive data and / or current from an attachment via the base component. For example, current can be provided to operate a heating device or sensor in the attachment or functional module. For example, data from sensors and / or data from functional modules forwarded by the attachment can be forwarded.

[0032] If both power and data need to be transmitted, electrical contacts can, in principle, be used for both functions, and possibly even simultaneously. However, different electrical contacts can also be provided for power and data. On the one hand, one or more power contacts can be provided to supply power to functional components such as heaters; on the other hand, one or more data contacts can be provided to transmit data. However, data contacts can also be configured to supply power to electronic components such as microelectronic devices or sensors.

[0033] In one embodiment, the food processor is configured to control the use of at least one electrical contact based on the type of the identified attachment. The use of the electrical contact may include whether a particular contact is activated (used). For example, a first type of attachment may use all electrical contacts, while a second type of attachment may not use at least one electrical contact. The food processor then influences the interface so that no electrical power or data is transmitted to the unused contact, and no electrical power or data is received from the unused contact.

[0034] For example, the first food preparation container may have two independent heating elements, which are powered through three electrical contacts. The second food preparation container may have only one heating element, which is powered through two electrical contacts. If the food processor detects the presence of the second food preparation container, a specific electrical contact is not used. Preferably, the food processor has access to information about which contacts have been used and / or not used.

[0035] The use of electrical contacts can include how specific contacts are controlled. For example, a third food preparation container may have a heating device that only allows the food in the food preparation container to be heated to 40°C. In this case, for the same purpose, i.e., applying current, the same contacts as in the second food preparation container are needed, but the current is limited to a low ampere. The food processor then limits the current to be applied to a preset value corresponding to the allowed heating.

[0036] In one embodiment, the food processor includes a position sensor for detecting the rotational position of an operating component. This position sensor is specifically arranged on a base component. Specifically, the position sensor is configured to at least determine the current rotational position. Preferably, the position sensor is configured to determine any rotational position of the operating component. This means that a specific position is not limited to that determined by an end stop. Specifically, any rotational position can be determined within the angular range in which the operating component can rotate. The rotational position of the operating component can very precisely indicate the function to be performed. For example, there may be an active position within a specific angular range for a particular attachment or functional module, where the specific function is active; and a passive position within another angular range, where the specific function is inactive. Therefore, the determined rotational position can directly and clearly indicate whether a specific function is active. The food processor can be configured such that the desired function, such as chopping food with a chopping tool, occurs only after a specific position has been detected, indicating, for example, that an attachment is locked to the base component. Specifically, the base component is configured such that the position sensor or a control device connected to the position sensor outputs a signal when the position sensor detects that a predefined rotational position has been reached. This allows for monitoring whether the desired rotation position has been reached, and enables food preparation to be carried out particularly quickly and safely.

[0037] In one embodiment, the position sensor is configured to detect the absolute rotational position of the operating component. Therefore, the position sensor provides the actual physical rotational position of the operating component within a possible angular range.

[0038] In one configuration, the position sensor has a signal element connected to an operating component and a detection device disposed on a base component. The detection device detects the position of the signal element. The signal element is, for example, a metal element.

[0039] The signal element can rotate together with the operating component. Specifically, no relative rotation occurs between the signal element and the operating component. Therefore, the rotational position of the operating component can be accurately and definitively inferred from the rotational position of the signal element, unaffected by tolerances (e.g., tolerances present in gearbox connection components). Specifically, the detection device is arranged on the non-rotating portion of the base component such that the signal element rotates relative to the detection device. There is no relative rotation between the detection device and the housing of the base component. In one configuration, the detection device has a curved shape about the rotational axis of the operating component. Specifically, the detection device has an arc shape. This ensures that the distance between the signal element and the detection device remains as uniform as possible regardless of the rotational position. Specifically, the detection of the detection device covers the entire angular range of rotation of the operating component. Specifically, the detection device is an inductive detection device.

[0040] Specifically, the food processor is configured to check whether the operating component is in its initial position and / or in which rotational position the operating component is. Knowing the initial position of the operating component may be necessary in order to couple the attachment to the base component. The food processor may be configured to perform the check during startup or each startup. If the operating component is in a different rotational position, the operating component may rotate to the initial position. The check may also be performed when the food processor detects the presence of a certain type of attachment. For specific operations of functional components, it may be necessary to know the specific rotational position of the operating component, such as the initial position or a specific position, such as a position known to the food processor (depending on the type of attachment), which indicates a specific state, such as a locked state.

[0041] In one embodiment, the interface has a receiving unit for receiving information used to identify the attachment type. Specifically, the receiving unit includes at least one electrical contact of the interface, particularly a data interface. In this case, the information is received via the electrical contact, which is configured only for receiving data, but may also be configured to transmit data if necessary.

[0042] Specifically, the attachment includes an identifier. For example, it may contain an electrically or electronically stored and / or digital identifier, such as a unique number. The attachment may have a data storage and / or control unit. In particular, the attachment includes a corresponding unit that can be coupled to a receiving unit of the interface for data transmission purposes. The receiving unit can then preferably receive data regarding the type of the attachment and, if applicable, its identifier. For example, the transmission can be analog or digital.

[0043] The receiving unit may have a data interface, which is particularly digital. This data interface is specifically used for data transmission. For example, power contacts used to supply power for the operation of functional modules are not contacts of the data interface. Preferably, the control device can receive sensor data and influence the function of the interface accordingly. The receiving unit and corresponding attachments may be designed as radio units. In particular, the receiving unit includes at least one electrical contact. In this way, data can be transmitted easily and without error.

[0044] In one implementation, the base component can access attributes of the identified attachment type. Specifically, the base component is configured to control the functionality of the interface based on the attachment's attributes. The food processor may have control devices capable of accessing these attributes. These attributes can be attributes of the identified attachment type. These attributes can be attributes of a specific identified attachment. These attributes can be used as a basis for controlling the interface.

[0045] For example, the food processor can access information about which one or more functions of the specified interface are used and, in particular, how those functions are used. For instance, a data log (e.g., a table) may be provided storing whether and / or how one or more of the electrical contacts, operating parts, and shafts are used for each type of attachment. This information (e.g., the data log) may be stored in the food processor and / or base component, such as in firmware, input to the base component or received from the mobile device, downloaded or provided via a network, stored in the attachment itself, and transferred from the attachment to the base component if necessary.

[0046] The attributes of an attachment may include, for example, one, several, or all of the following: the possible type of food preparation; whether it can be locked; how it can be locked (e.g., the direction and / or angle of rotation of the operating part); the volume, area, presence, number, and type of the heating device; the presence, number, and type of sensors; the presence of a rotatable tool; the function of the tool, for example, depending on the direction and / or speed of rotation; the possibility of coupling with a functional module; which functional modules can be coupled; whether the functional module can be locked; which functions of the functional module can be controlled; how the function of the functional module is controlled (e.g., the direction and / or angle of rotation of the operating part); and so on.

[0047] For example, the control device can then control only the electrical contacts of the interface associated with the identified attachment, and only perform the set rotation of the operating component or shaft. It does not control all electrical contacts of interfaces that are not present or unused. It does not execute unintended rotational directions or speeds of the operating component.

[0048] In one configuration, the food processor includes an attachment. In one embodiment, the attachment is a food preparation container. In another embodiment, the attachment has an interface for mechanical coupling with a functional module. Specifically, the interface is located on the upper side of the attachment. The functional module is configured to be positioned, specifically from above, on or within the attachment. The food processor may include functional modules.

[0049] A functional module is a component used with an attachment and performing a specific function. A functional module may be a cover that at least partially covers the attachment. A functional module may be, for example, a lid to prevent insertion and / or spillage. A functional module may be configured to perform one or more specific food preparation processes. A functional module may be a chopping component for chopping food. A functional module may be, for example, a cutting unit, such as a cutting disc, grater, or juicer, and / or a juicer attachment. A functional module may be a single piece or a multi-piece assembly. A chopping attachment may, for example, include a collection basket, chopping tools, a connecting shaft, and a lid. This attachment may form a popcorn machine alone or together with the functional module.

[0050] Specifically, different functional modules can be provided, each of which can be combined with one or more different attachments. Specifically, the interfaces of the different attachments are shaped to correspond to each other. Specifically, each functional module has a corresponding interface for coupling with the interface of the corresponding attachment. Mechanical coupling can be press-fit and / or form-fit coupling. Form-fit coupling typically occurs, at least in the transverse direction to the axial direction. In this way, the functional module can still be removed upwards, but will not slip laterally. For example, a drive mechanism of the attachment can be used to lock the functional module to the attachment. In the locked position, a lock, particularly a form-fit lock, can be formed, preventing the functional module from being removed from the attachment.

[0051] In one embodiment, the food processor is configured to identify the presence and / or type of a functional module. Specifically, the food processor is configured to influence the function of the interface based on the identified presence and / or type. Similar to the type of attachment, the type of functional module can also be used to influence the function of the interface. The above statements regarding influencing the interface similarly apply here. Furthermore, information about the absence of a functional module can also influence the function of the interface. For example, if it is detected that there is no lid on the food preparation container, the rotation of the rotatable tool can be restricted to a low speed or even prevented from rotating.

[0052] The food processor can use available information to enable, disable, or activate specific operations of specific functional components via at least one modified parameter. For example, modified speed, rotation direction, or temperature of the heating device can be used as a parameter.

[0053] Specifically, the food processor (preferably an attachment) includes at least one receiving unit for receiving information used to identify the type of functional module. In one configuration, the receiving unit includes at least one sensor for identifying the type of functional module. This sensor can be configured to detect a magnetic field. For example, at least one Hall sensor, particularly a 3D Hall sensor, can be used. In this way, a three-dimensional vector of magnetic flux density can be measured. One or more magnets can be arranged on the functional module, which can be used to encode the type of the functional module. Specifically, two or more magnets are used. Specifically, two or more Hall sensors are used. For some applications, a single Hall sensor may be sufficient.

[0054] Alternatively, any other suitable sensor may be used. For example, a resistor may be arranged in each functional module, which can be read out via electrical contacts on the functional module. Each type of functional module has a characteristic resistance that the food processor can use to identify its type. Typically, the attachment includes suitable electrical contacts to create an electrical connection from the functional module to the base component when the functional modules are coupled, and / or to query the resistance.

[0055] It can also receive data about the type of functional module. For example, a near-field communication or Bluetooth transmitter can be set in the functional module, and a corresponding receiver can be set in the food processor. The identifier stored in the functional module can also be read by the attachment or base component, similar to the identifier of the attachment described above, and applies accordingly here.

[0056] The receiving unit is used to identify the type of functional module. The receiving unit can be configured to output an electrical signal encoding the type of the functional module. The receiving unit is preferably located on the attachment. Specifically, a data connection can be established or exist between the attachment and the base component, through which electrical signals can be transmitted to control devices in the base component. The data connection can be wired or wireless. One segment of the data connection can be formed by one or more electrical contacts as part of an interface. The receiving unit can also be located on the base component. For example, a corresponding signal can be transmitted from the attachment to the base component.

[0057] In one configuration, the food processor is configured such that the function of the interface performs actions on the functional module. In one embodiment, the attachment has a transmission mechanism, particularly a mechanical transmission mechanism, for transmitting force and / or motion of the operating component, especially for performing functions on the functional module. In this case, the transmission mechanism may have elements that interact with contact elements of the operating component. The transmission mechanism can be configured to transmit motion to the functional module. For this purpose, the transmission mechanism and the functional module may also have corresponding contact elements. The functions in the functional module include, for example, the movement of components of the functional module. The movement of the components can produce various results, such as opening or closing an opening or valve, indicating a status, etc. The transmission mechanism may, for example, be rotatable, particularly rotatable about the same axis of rotation as the operating component.

[0058] Alternatively or additionally, the transmission itself can perform the function. The transmission may have a locking element on its upper side, which can be used to lock the functional module to the attachment. For example, the transmission and / or functional module has one or more form-fitting elements. Another corresponding component is shaped such that, when the transmission and functional module are in a suitable relative rotational position (i.e., the locked position), this component engages with the form-fitting element, forming a rigid lock. This prevents the functional module from being removed from the attachment. In another rotational position (the released position), the lock is released, and the functional module can be removed, particularly manually. One or more form-fitting elements may also be arranged on the functional module. In principle, a press-fit lock can also be provided, for example, by applying force to a rubber or spring element.

[0059] The transmission mechanism can be arranged between the inner wall and the outer wall of the attachment. A heat insulation layer can be provided between the inner and outer walls, or the outer wall itself can be designed as a heat-insulating structure. It can be specified that the attachment can only be coupled to the base component when the transmission mechanism is in its initial position. A biasing element, including, for example, one or more springs, can be provided to bias the transmission mechanism to the initial position. This ensures that the attachment can always be easily coupled to the base component.

[0060] In one embodiment, the base component and the attachment are configured such that the attachment can be mechanically coupled to the base component in the initial position of the operating component. The attachment can then be placed onto the base component, and in particular, can be manually removed. In another embodiment, the base component and the attachment are configured such that the attachment locks to the base component in a second rotational position of the operating component, different from the initial position. Specifically, this locking occurs via a contact element of the operating component, as described. In this position, the attachment can generally neither be placed onto nor removed from the base component.

[0061] Specifically, the base component and the attachment are configured such that when the operating component is in a third rotational position different from the initial and second rotational positions, at least one locking element of the attachment, operatively connected to the transmission, is in a locked position to lock the functional module. Alternatively, another action can be performed on the functional module in the third rotational position. Specifically, the initial position, the first rotational position, and the second rotational position are passed sequentially in this order. If the operating component rotates from the initial position in a rotational direction, the attachment is locked. If rotation continues in that rotational direction, the functional module is locked, or another action is performed. One or more additional actions can be performed before locking and / or between steps.

[0062] In one embodiment, the food processor is configured to perform a predetermined action if an attempt to rotate the operating component to a desired position fails. The predetermined action depends in particular on the type of attachment and / or functional module identified. For example, the operating component may not be able to be rotated to the locked position, for example, due to improper attachment of the attachment or functional module, contamination, or damage. The food processor then performs the predetermined action. For example, it may prevent the desired operation, allow or perform an operation with at least one changed parameter, and / or output information to the user. The action may also depend on the identified position and / or the current operation of the food processor. If a lid is identified on the food preparation container and a malfunction occurs during locking, the operation of the cutting tool may be prevented or restricted. On the other hand, if a malfunction occurs during unlocking, only information may be output to the user.

[0063] In one embodiment, the food processor is configured to adjust the functionality of its interface based on the current operating state of the food processor. Specifically, the control device has information about the current operation. The current operation may include, for example, temperature, speed, rotation direction, the status of attachments, the status of functional modules, the locking status of attachments, the locking status of functional modules, and / or operating parameters set and / or specified by the user or recipe. The current operation can provide information about the current state of the attachments or the food within them. For example, when cooking potatoes, if a high temperature (e.g., 95°C) is reached, locking may be necessary to prevent the lid from being removed directly.

[0064] In one embodiment, the functional module is a cover for covering the attachment. In one embodiment, the functional module is in a raised position when a force from below or inside is applied to it. Specifically, the functional module cannot be unlocked in the raised position. Specifically, the food processor is configured to identify whether the type of attachment and functional module allows the functional module to be in the raised position. Specifically, if this is the case, the food processor can be configured to insert a certain waiting time after a failed attempt to unlock the functional module, and then make another attempt to unlock the functional module. Specifically, the food processor has information about the movement required to unlock the functional module.

[0065] The functional module can be pushed upwards by a force acting on it from below. This force can be caused by factors such as excessive internal pressure within the attachment, the formation of eddies within the attachment (i.e., a funnel-shaped liquid surface caused by rotation), or overfilling of the attachment. This force specifically originates within the attachment and acts on the lower side of the functional module. The attachment and / or functional module can be designed such that mechanical unlocking is impossible when such a force is present. For example, a locking element can interact with a guide rail, causing the locking element to move against a stop due to a change in the functional module's position, thus preventing unlocking. When the force is removed or reduced below a threshold, the functional module descends again, the locking element moves past the stop, and unlocking is achieved. This mechanism can be referred to as a pressure chamber.

[0066] The food processor can detect a failed attempt, for example, by observing an increase in motor current within a specific range of the operating part's rotational position when it is rotated to the unlocked position. The food processor can then rotate the operating part back to the locked position. When another attempt is made, the actuating part rotates toward the unlocked position again. This may result in unlocking, or another failed attempt may occur. This can be repeated several times if necessary, until unlocking occurs. A waiting time of, for example, a few seconds, particularly at least one second and / or at most ten seconds, can be provided. In this example, the attachment is not specifically a pressure cooker. Pressure cookers typically have valves for releasing pressure.

[0067] In one configuration, the food processor includes a control device. The control device can be configured to control the food preparation process using attachments. This control can be performed according to the identified attachment type. The control device can be configured to control an interface, operating components, and / or one or more electrical contacts of a shaft. Control can be based on, for example, electronically stored recipes, user-selected operating modes, or user-input instructions. Control can include whether and / or how a function is activated. The control device is particularly located in a base component. Preferably, the control device includes a processor and a memory having computer program code (i.e., commands that can be stored in a memory). The processor, memory, and computer program code are configured to enable the execution of a method having several process steps.

[0068] In one embodiment, the food processor is configured to perform interface functions based on user input or electronically stored recipes. Specifically, the food processor is configured to perform interface functions in response to user instructions or recipes, depending on the type of identified attachments and / or functional modules. In this embodiment, specific instructions may be executed differently or variably depending on the attachments and / or functional modules used.

[0069] For example, if a recipe or user specifies that food should be heated in a pot, the food processor identifies the type of pot and has information about which heating elements are available for that pot and, in particular, how to control those elements. In this way, the food preparation process can be performed in a partially automated manner. Appropriate voltage and / or current are then supplied to the required electrical contacts and controlled appropriately. Specifically, the type and duration of the corresponding operation are specified by the recipe.

[0070] This function can be triggered in response to user input or pending recipe steps. It can be executed based on user input or the recipe. For example, the user can set it through the user interface, or the recipe can specify the tool to rotate at a specific speed using electronically stored data.

[0071] For example, a recipe might specify that the attachment and / or its lid must be locked, for instance, if, according to the recipe, the volume or mass of food in the attachment exceeds a threshold and / or if the temperature in the attachment or the rotational speed of the tool exceeds a predefined threshold. The food processor has information regarding the identified attachment and / or lid locking, which is accomplished by rotating the operating part from its initial position by a specific angle in a particular direction. The food processor influences this function based on the type of attachment, such that, in response to the recipe instruction, the operating part rotates in the desired manner, thereby locking the attachment to the base component. If both the attachment and the lid need to be locked, the operating part typically rotates a larger angle. This function can also be adjusted during recipe processing in response to the achieved operational state.

[0072] In another example, the user can set a specific blending speed. If the food processor detects that there is no lid on the attachment, it can limit the blending speed. If necessary, the speed will be reduced (deviating from the user-set value) to improve safety. The direction of rotation can also be affected in this way. If a mixing blade is used that blends in a first direction and chops in the opposite second direction, the rotation can be restricted to the first direction when there is no lid.

[0073] In one configuration, the food processor is configured to at least partially automate food preparation based on an electronically stored recipe. The food processor's control unit can access the recipe and is driven by a recipe step within it, thereby operating functional components in a manner defined by that recipe step. The recipe can be configured to select at least one recipe step based on an identified attachment type. For example, it can be specified that the onion-frying step must be completed in two steps when using a small attachment, while it can be completed in one step when using a large attachment. The food processor can then select the recipe step to be executed based on the attachment type. Alternatively, the food processor can modify a recipe step to execute a recipe originally applicable to a first type of attachment via a different second type of attachment.

[0074] In one embodiment, the food processor is configured to check (particularly before or during operation of a functional component) whether the operation is permitted for the type of the current attachment and / or functional module, based on instructions or recipes from the user. In another embodiment, the food processor is configured to avoid operating the functional component according to user instructions or recipes if operation is not permitted according to user instructions or recipes.

[0075] If an operation is not permitted, it can be omitted entirely. For example, without a lid, chopping chocolate cannot be performed. Alternatively, in this case, the operation can be performed using at least one modified parameter. For example, without a lid, the soup can be stirred at a reduced speed or kept warm at a lower temperature. In this case, the operation according to the instructions is also omitted, and a different operation is performed instead. This increases safety.

[0076] For example, before each change to a parameter used to operate a functional component, the food processor checks whether that parameter is permitted for the identified attachments and / or functional modules. This check can also be performed, for example, at specific intervals during parameter changes. For instance, when the temperature rises above a certain level, it may be necessary to cover the container to prevent boiling over. However, locking the lid may not be necessary. To account for such continuous changes during operation or before startup, checks can be performed at regular time intervals.

[0077] This food processor can be configured to provide information to the user. It can specify the exact reason for any discrepancies so the user can take remedial action, such as closing the lid. Once the cause is corrected, it can detect that the attachments and / or functional modules are in place and initiate the necessary operation.

[0078] Another aspect of the invention is a method for preparing food using a food processor according to the invention. The method specifically includes the food processor identifying the type of attachments mechanically and / or electrically coupled to a base component. The method specifically includes the food processor influencing the function of an interface based on the identified type of attachment. This influence may include moving an operating component of the interface to a position predetermined by the type of attachment and / or the operating state of the food processor. Alternatively or additionally, this influence may include controlling or activating at least one electrical contact in a manner predetermined by the type of attachment and / or the operating state, and / or rotating a shaft in a manner predetermined by the type of attachment and / or the operating state.

[0079] In one embodiment, the method includes the food processor identifying the type of a functional module mechanically coupled to an attachment. Specifically, the method includes the food processor influencing the function of an interface based on the identified type of functional module. This influence may include moving an operating part of the interface to a position predetermined by the type of functional module and / or the operating state of the food processor. Alternatively or additionally, the influence may include controlling or activating at least one electrical contact in a manner predetermined by the type of functional module and / or the operating state, and / or rotating a shaft in a manner predetermined by the type of functional module and / or the operating state.

[0080] Exemplary embodiments of the invention are explained in more detail below with reference to the accompanying drawings. Unless otherwise stated, features of the exemplary embodiments may be combined with the claimed subject matter individually or in multiple forms. The scope of the claims is not limited to the exemplary embodiments. Attached Figure Description Figure 1 Side view of the base component. Figure 2 : Partially transparent magnified details of the base component. Figure 3 : The interface of the attachment, Figure 4 A partially transparent side view of the attachment to which functional components are attached. Figure 5 and 6 A diagram showing the functions of the operating components, and Figure 7 : A schematic diagram of a food processing machine.

[0081] Figure 1 A food processor including a base component 3 is shown. The base component 3 includes a support leg 31 located on its lower side and is configured to rest on a kitchen countertop. The base component 3 includes a touch-sensitive display 30 on its upper side for input and output, and an interface 9 for mechanically and electrically coupling attachments to the base component 3. The interface 9 includes an operating component 10 having contact elements 13 and insertion elements 11, which... Figure 2 This can also be seen in the text.

[0082] Figure 2 The base component 3, having interface 9, is shown in enlarged form in the oblique top view. The base component 3 includes a shaft driven by an electric motor for driving a tool or tool holder in the attachment. The shaft has a non-circular profile 35 on its upper side, which is rotatably coupled to a corresponding profile 35' of the attachment, such as, for example… Figure 3 As shown. Contour 35 is typically located at the center of interface 9. Interface 9 also includes electrical contacts 17 located beneath the cover. Electrical contacts 17 are used to transmit electrical power and / or information to and / or from the attachment. Interface 9 typically includes a cover ring that may include the cover and three insertion elements 11 evenly distributed around the circumference, each insertion element having a chamfered edge and serving as an insertion aid when coupling the attachment.

[0083] The operating member 10 is annular and includes three contact elements 13 evenly distributed around its circumference. The operating member 10 is rotatable about its vertical axis via an actuator 12 (particularly via a transmission mechanism, exemplarily shown here as a gear 33), which preferably coincides with the axis of the shaft. In the initial position of the operating member 10 shown, the contact elements 13 are aligned with the insertion element 11 above it and the locking hook 37 below it, as described below. The contact elements 13 have contact surfaces 14 and are used to perform various functions, particularly on the attachment. For example, the attachment may be locked to the base member 3, or rotational movement or force may be transmitted to the transmission mechanism of the attachment.

[0084] Below the operating component 10 is a locking ring with outwardly protruding locking hooks 37 arranged on it. Two locking hooks 37 are visible, while a third locking hook 37 is hidden. Figure 3 The attachment 5 shown includes an interface 9' located on its lower side, through which the attachment can be mechanically and electrically coupled to the interface 9 of the base component 3. When the attachment 5 is locked, the assembly consisting of the insertion element 11, the contact element 13, and the locking hook 37 (see [link to documentation])... Figure 2The attachment 5 engages in the recess 39 within the connecting ring 40. The connecting ring 40 is rotatably mounted in the attachment 5. When the operating member 10 is now rotated, the contact surface 14 of the operating member 10 contacts the boundary of the recess 39, and the contact element 13 causes the connecting ring 40 to rotate together. During this process, material on the connecting ring 40 adjacent to the recess 39 moves between the locking hook 37 and the insertion element 11. In this way, the attachment 5 is locked to the base member in a form-fitting manner, at least in the axial direction. Furthermore, this design allows the connecting ring 40 to rotate further while the attachment 5 remains locked. In particular, the attachment 5 and / or the interface 9 also include form-fitting elements to prevent the attachment 5 from rotating within the interface 9.

[0085] When the attachment is placed on the interface 9, the electrical contact 17' of the attachment 5 is also connected to the electrical contact 17 of the interface 9. The specific design of the corresponding contacts 17 and 17' is not critical. In addition, the outline 35' of the attachment 5 is connected to the outline 35 of the interface 9 by rotation.

[0086] Figure 2 The base component 3 is schematically shown to include a position sensor 20, which determines the rotational position of the operating component 10. Specifically, the detection device of the position sensor 20 is directly or indirectly connected to the housing of the base component, while the signal element is directly connected to the operating component 10. Therefore, the detection device can directly and very accurately determine the rotational position of the operating component 10. Furthermore, the food processor (particularly the base component 3) includes a receiving unit 19, which receives information about the type of attachment. Preferably, the receiving unit 19 includes at least one electrical contact 17, particularly an interface 9, as shown. The attachment can then transmit electrical or electronic data identifying at least the type of attachment to the base component. Preferably, the food processor (particularly the base component 3) also includes a control device 18.

[0087] In the configuration shown here, connecting ring 40 (see...) Figure 3 ) is the transmission device 25 (see Figure 4 As part of the attachment 5, the transmission device extends within the wall of the attachment 5 or between the inner and outer walls of the attachment 5 and... Figure 4 As can be seen, the transmission device 25 extends specifically from the interface 9' on the lower side of the attachment 5 to another interface 6 on the upper side of the attachment 5. The transmission device 25 is shown in dashed lines because it is located behind the outer wall of the attachment 5. The functional module 7 can be mechanically coupled and, if necessary, electrically coupled to... Figure 4 Interface 6 is shown. Figure 4In this configuration, attachment 5 is, for example, a food preparation container with a handle 8, and functional module 7 is a lid that can be locked onto attachment 5. The transmission device 25 can be rotated by rotating the operating member 10 along its central vertical axis of rotation.

[0088] The transmission device 25 may have a form-fitting element in its lower region, for example, for locking the attachment 5 to the base member 3. In the above... Figure 3 In the example, these shape-fitting elements are part of the connecting ring 40. In one example, the transmission may include a bayonet geometry on its underside. It can be specified that the operating component 10 rotates this bayonet geometry, thereby creating a lock. Thus, in a first rotational position of the transmission 25, the functional module 7 is locked to the attachment, and in a different second rotational position, the functional module 7 can be detached from the attachment 5.

[0089] The transmission device 25 may have a form-fitting element in its upper region that engages with a corresponding element of the functional module 7, for example, to lock the functional module 7 to the attachment 5. A bayonet geometry 44 may be present on the upper side of the transmission device. In the exemplary embodiment shown herein, the functional module 7 includes a hook 42 that engages with a ring 46 on the upper side of the attachment. As described above, a pressure chamber 47 may be provided in which the locking element moves against a stop, thereby preventing the raised cover from unlocking.

[0090] Furthermore, the attachment 5 may include a receiving unit 23 for receiving information used to identify the type of the coupled functional module 7. The receiving unit 23 may transmit corresponding data to the base component via electrical contacts at the interface 9' of the attachment 5.

[0091] The food processor can be configured to perform one, several, or all of the following scenarios.

[0092] In scenario A), the pot is used as an attachment. There are no functional modules. The pot does not need to be locked to the base component. No operating components are used. The food processor can identify the type of attachment and, if applicable, identify the absence of functional modules, and / or check whether the available components allow the desired operation, and accordingly perform the operation, either in a modified form or prevent the operation (do not perform the operation). The operating components can be identified as being in their initial position. For example, the heating element of the pot can be operated by applying current to one or both electrical contacts.

[0093] In scenario B), the pot serves as an attachment, and the lid as a functional module. After identifying these components, the food processor can control the operating mechanism to lock the pot to the base component, and specifically, to lock the lid to the pot. When heating with the lid locked, unexpected forces may be applied to the lid inside the pot. The functional module and attachment can be designed so that the functional module can be pushed up by excessive pressure, while the pot remains tightly closed. When attempting to unlock the functional module, the inability to unlock can be detected, for example, by excessive current consumption of the actuator. This can be achieved, for example, through the described pressure chamber. After a waiting period, the food processor can attempt to unlock the functional module again.

[0094] Figure 5 A diagram illustrating the function of an embodiment of a food processor, depending on the rotational position of the operating component, is shown, for example, in scenario B). The food processor includes a pot-shaped attachment mechanically coupled to a base component, and a lid-shaped functional module mechanically coupled to the pot. A rotation angle α is plotted on the x-axis, characterizing the rotational position of the operating component. An initial position 50 (defined as 0°) is an unlocked position, in which the pot can be removed from or placed on the base component, and in which the lid can be removed from or placed on the pot. The initial position 50 may correspond to... Figure 2 The position is shown. A confidence range 56, for example ±1°, can be set around the initial position 50 to compensate for measurement errors.

[0095] As the operating component rotates in the direction designated as the locking direction during the first rotation 61, it first reaches an intermediate position 51, which can be approximately 12°. In this position, the overlapping portion of the operating component and the locking hook has separated by about half. Prior to this position, the actuator can be allowed to consume greater power to cope with contamination that may occur over time (e.g., contamination of the locking hook area). This prevents locking failure.

[0096] If the operating component rotates further in the rotational direction during the second rotation 62, a third rotational position 53 is reached, which corresponds to the locked position of the lid on the pot. Whether the pot is locked to the base component is not important here. Further rotation in the rotational direction is not specified in this example. The area to the right of the third rotational position 53 is the overtravel zone 57, which is not reached in a fault-free system. This zone can only be entered in the event of a fault.

[0097] When an external force simultaneously pushes the lid upwards to its raised position, a third rotation 63 of the operating component in the opposite unlocking direction will not immediately unlock it. The rotation only proceeds to the fourth rotation position 54. For example, at this point, it is close to the pressure chamber described above. Once the lid returns to its normal position, a fourth rotation 64 can be performed to reach the fifth rotation position 55, allowing passage through the pressure chamber. Subsequently, in the fifth rotation 65 (which can be completed in one step with the fourth rotation 64), the lid can be unlocked.

[0098] There may be another second rotational position 52, in which only the pot is locked to the base component, while the lid is not locked. This position is advantageously located between the initial position 50 and the fourth rotational position 54, and particularly as shown in the figure, between the intermediate position 51 and the fourth rotational position 54.

[0099] If the attachment or functional module fails to lock, one or more further attempts (e.g., three attempts) can be made to achieve locking. There is typically no waiting time between these attempts. If the attachment or functional module cannot be unlocked, the proximity to the pressure chamber can be checked, for example, based on the rotational position of the operating part. If so, one or more more attempts (e.g., four attempts) can be made to unlock the attachment or functional module again. Waiting time is typically inserted between these attempts. The waiting time after each repetition can be progressively increased (e.g., 2 seconds, then 3 seconds, then 4 seconds, then 5 seconds). If this still doesn't work, one or more retrying attempts (e.g., three) can be made to achieve unlocking, typically without waiting time.

[0100] In scenario C), the pot is used as an attachment. A functional module exists that includes a cutting attachment. An operating part is used to lock the pot and the functional module. No force can be applied to the inside of the lid. If the type of functional module used is identified, any one or more heating elements are deactivated.

[0101] Similar to Figure 5 , Figure 6 The functionality of a food processor design, depending on the rotational position of the operating components, is illustrated, for example, in scenario C). The locking and unlocking of functional modules on attachments is also relevant here. The functionality is similar to that described above; to avoid repetition, only the differences will be discussed. Locking is immediately achieved via a third rotation 63 when rotating in the unlocking direction.

[0102] If an attachment or feature module is not unlocked successfully, one or more further attempts (e.g., three attempts) can be made to unlock it. There is usually no waiting time between these attempts.

[0103] In scenario D), a different pot is used as an attachment. A functional module in the form of a lid is present. The pot or lid is not locked in this scenario. One or both of the pot's heating elements can be heated via corresponding electrical contacts. The pot may include an optional operable rotatable tool. Rotating operating parts are not required in this scenario.

[0104] In scenario E), a pressure cooker is used as an attachment, and a pressure-resistant cap with a controllable valve for pressure relief is used as a functional module. An operating component can be used to control the valve, specifically by using a transmission mechanism. In addition... Figure 5 or Figure 6 In addition to or as a substitute for some or all of the rotational positions shown, there may be a sixth rotational position, in which the valve is closed; a seventh rotational position, in which the valve is minimally opened, for example, to release high pressure; an eighth rotational position, in which the valve is partially open, for example, to 50% open; and / or a ninth rotational position, in which the valve is fully open. The sixth rotational position may be at 0°, the seventh rotational position may be slightly above 0°, the eighth rotational position may be at 8°, and / or the ninth rotational position may be at 16°.

[0105] In scenario F), a pressure cooker is used as an attachment, and a lockable pressure-resistant lid with a controllable valve for pressure relief is used as a functional module. In addition to controlling the valve, an operating component is used to lock and unlock the cooker. Figure 5 or Figure 6 In addition to or as an alternative to some or all of the rotation positions shown, the following rotation positions may exist: a sixth rotation position, corresponding to the base position and / or the 0° position, where the valve is closed and the pot is not locked; a seventh rotation position, in the form of the intermediate position described above, for example, at 12°; an eighth rotation position, where both the pot and lid are locked and the valve is closed, for example, at 30°; and further rotation positions in which the pot and lid remain locked while the valve is opened as follows: a ninth rotation position, where the valve is opened to a minimum, for example, 1% of full opening, for example, at 31°, for example, to release high pressure; a tenth rotation position, where the valve is half-open, for example, at 38°; and / or an eleventh rotation position, where the valve is fully open, for example, at 46°. One or more heating devices may be used in the same manner as in scenario D).

[0106] Figure 7 A food processor 1 is shown, which includes a base component 3 having an interface 9 for mechanical and electrical coupling with an attachment 5. The attachment 5 is inserted into the interface 9.
