A mixing machine includes a head extending over a bowl receiving location, the head including a downwardly extending rotatable output shaft for receiving a mixer tool, the head including a planetary system therewithin for effecting rotation of the rotatable output shaft about its axis and orbiting of the shaft axis about another axis. A motor includes an output operatively connected to drive the planetary system. A control system includes a plurality of sensors, each sensor located for detecting a respective condition of mixing machine, and a diagnostic control operable to (i) track outputs from the plurality of sensors over time, (ii) analyze the tracked outputs and (iii) produce an alert indication based upon the diagnostic control identifying a performance characteristic indicative of a need for service or repair of the mixing machine.

A device and method for aerating a food substance. The device includes: an aerator, a vessel, a drive unit and a mounting. The aerator includes a plurality of filaments attached at their proximal ends and being free at their distal ends. Every filament has a first state and a second state. The filament undergoes a reversible elastic deformation when being bent by a transverse force from the first state to the second state. The filament performs a spring-back action from the second state to the first state, lowering the spring tension, when the transverse force acting on the filament drops to zero. The aerator is attachable to and rotatable by the drive unit thereby defining an axis of rotation. The vessel defines a space for holding the food substance being bordered at the sides by an inner wall. The vessel and the drive unit are attachable to the mounting. The mounting defines a spatial relationship between the axis of rotation and the inner wall of the vessel such that the distal ends of a fraction of the filaments contact the inner wall of the vessel, wherein the inner wall bends the fraction of the filaments by applying the transverse force.

A stand mixer includes a motor output shaft and a locking planetary output. The locking planetary output has a center shaft operably connected with the output shaft for driven rotation about a fixed axis, an agitator shaft mounted to the center shaft such that the agitator shaft moves around the fixed axis of the center shaft in a planetary arrangement, and a planetary gear centrally arranged about the fixed axis of the center shaft. A gear unit is rotatably fixed on the agitator shaft and is slidably mounted therewith to be moveable between a first position, in which the gear unit is engaged with the planetary gear, and a second position in which the gear unit is disengaged from the planetary gear and is engaged with a locking member.

A household appliance for culinary preparation includes a base intended to rest on a worktop and a head mounted movable relative to the base, the base forming a stand, the base having a control panel tilted backward relative to the stand, with a backward inclination of between 5 and 45 relative to the direction perpendicular to the work surface. The base has a primary upright member adjacent to the stand. The head is mounted on the primary upright member. The base has a secondary upright member rising from the stand laterally relative to the primary upright member and the head. The secondary upright member is connected to the primary upright member.

The secondary upright member rises away from the head and the control panel is arranged on the secondary upright member.

A cooking apparatus is disclosed, which comprises a first housing provided with an inverter for induction heating; and a second housing including a working coil to which a current supplied from the inverter is transferred, heated as a container for receiving cooking food is arranged thereon, wherein the first housing and the second housing constitute spaces detached from each other.

A bench or stand mixer includes a bowl that contains ingredients, a motor that drives an accessory, for example a beater, to process the ingredients, and a sensor. The sensor provides a signal indicative of a change in the ingredients, with the sensor cooperating with a controller, for example a processor, to control the speed of the motor, in response to the change in condition of the ingredients.

The present disclosure discloses a double-locking head structure of a cook machine. The double-locking head structure includes a securing component and a driving component. The securing component includes two securing bases and two bolts. The two bolts are respectively received in two grooves which are respectively defined in a middle portion of the two securing bases. The driving component is configured to drives the two bolts to separate from the two grooves. The present disclosure can fix a main body and a main body of a cook machine or other device by using the two bolts and securing block, thereby improving the fixing effect of the fixing structure, and simultaneously it is convenient to open and close the device are convenient and improve the work efficiency. A cook machine comprising the double-locking head structure is also provided.

A stand mixer appliance is provided. In one example implementation, the stand mixer can include a base, a housing, a mixer shaft rotatably mounted on the housing, and a motor assembly. The motor assembly can include a motor drive and a motor operably coupled to the mixer shaft. A controller can be operably coupled to the motor drive. The motor assembly can further include a sensorless feedback system configured to obtain feedback measurements of one or more electrical characteristics from the motor. The feedback system can include an observer configured to process the one or more electrical characteristics and provide data indicative of a position or a speed of the motor. In turn, the controller can operate the motor drive based at least in part on the data indicative of the position or the speed of the motor.

A method for operating an appliance, such as a stand mixer appliance, is provided. In one example implementation, the method can include operating a motor of the stand mixer appliance in order to rotate a mixer shaft of the stand mixer appliance. The method can further include determining, via a controller of the stand mixer appliance, a difference between an operating parameter and an operating parameter threshold. The method can further include implementing, via the controller of the stand mixer appliance, a field-weakening operation to increase a speed of the motor based at least in part on the difference.
