In one embodiment, a device includes an inner shell having an inner surface and an outer surface, an outer shell having an inner surface and an outer surface, the inner surface of the inner shell defining a liquid holding volume and the outer surface of the inner shell and the inner surface of the outer shell defining a vacuum chamber. The outer shell and inner shell can be configured to form an orifice to the liquid holding volume at their junction. The device can be configured to prepare a liquid food item for consumption, including by powering a heating element and mixer device that can be configured to respectively heat and mix a liquid food item in the liquid holding volume.

A food processing appliance includes a container having a rotational processing assembly that includes an inner portion of a magnetic coupler. A base has a drive system for providing a rotational drive force. A drive rotor selectively transfers the rotational drive force to the magnetic coupler. The drive rotor includes a plurality of drive-magnetic members that form an outer portion of the magnetic coupler. The inner portion and outer portions of the magnetic coupler selectively and magnetically engage to form an engaged position. The engaged position is further defined by the inner portion being completely separated from the outer portion to define a gap therebetween.

A device for storing and circulating drinking water with vortex flow includes a base, a tank and an actuator housed in the base and configured to circulate the drinking water stored in the tank with vortex flow. The base includes an inlet port through which the drinking water is received and an outlet port through which the drinking water is dispensed. The tank is mounted on the base with a sealed engagement and is configured to store the drinking water. The tank has spherical or egg shape and includes an air inlet on an upper portion of the tank through which air can flow in and out of the tank.

A motor is generally described. The motor may include an armature and a coil. The coil and armature operatively receive power from a power source. The power induces magnetic fields in the coil and armature to drive the armature. When power is removed, the coils reverse polarity to inductively decelerate the armature.

This disclosure relates to a processing device (1) of food products and drinkables, which uses space-varying magnetic field for blade (6) rotation (i.e., it has a magnetic coupling between components in the blender base (2) and in the cover (7) of the blender jar (3), works in a principle of an inverted flask, consists of two separate parts, one of which is a removable flask with a built-in second component of the magnetic coupling (21) and the base with an electric motor (19) and a first component (20) the magnetic coupling. The second magnetic coupling component, which is integrated in the cover (7), has a disc (8) of electrically conducting metal (aluminum, copper or other material suitable for magnetic coupling may be used), in which Foucault currents can be induced. The disc (8) may be replaced by a holder (10) with two (or more) permanent magnets (11), which are added to suit to the magnetic coupling requirements.

Provided is a device, comprising: a barrier configured to impeded or prevent particles shed by a robot in a first volume of space from entering a second volume of space in which the robot manipulates a workpiece; and a robot having three or more degrees of freedom, the robot comprising: a first portion disposed on a first side of the barrier in the first volume, the first portion comprising an actuator of the robot, the actuator being configured to drive movement of the robot to manipulate the workpiece; and a second portion disposed on a second side of the barrier in the second volume, the second portion comprising an end-effector of the robot by which the robot makes contact with the workpiece.

A handheld electric milk frother including a handle and an immersing portion coupled with the handle. The immersing portion includes a cap and a rotatable frothing means coupled with the cap. The frothing means includes a substantially closed ring member formed by a first half ring member and a second half ring member joining with each other, with the first half ring member oriented horizontally and the second half ring member oriented obliquely relative to the first half ring member and extending downwardly from the first half ring member, so that an obtuse angle is formed between the first and second half ring members; and a plurality of coils wound on the substantially closed ring member. The cap has an upper part and the upper part has the largest cross section thereof larger than and sufficient to cover the largest cross section of the substantially closed ring member.

An apparatus for use with an induction heating element is disclosed. The apparatus includes a ferromagnetic base to convert magnetic energy from the induction heating element into thermal energy, an induction coil to convert magnetic energy from said induction heating element into electrical energy, a waterproof housing containing an electronic circuit conductively coupled to the induction coil; and a motor controlled by said electronic circuit using the electrical energy; and an agitator driven by the motor. Also disclosed is a system that includes the induction heating element, an apparatus, and a method of heating and stirring a food product in a diamagnetic container using the apparatus on the induction heating element.

Disclosed is a cold brew coffee maker and related methods of making cold brew coffee. The cold brew coffee maker can include a rotation plate assembly, a removable cup, a brew chamber and a filtration assembly. The rotation plate assembly can include an internal magnetic component for generating rotational movement of a selectively attachable component of the cup.
