  • Publication number: 20230200581
    Abstract: To enhance extraction and dissolution of soluble components of a solid material in water to make a beverage, an appliance comprises a serving chamber, a pressure regulating system, a filter assembly, a brewing chamber, a liquid passageway and a controller that controls the pressure regulating system to alternately de-pressurize and pressurize the brewing chamber is provided. The appliance further comprises a foam filter to reduce the amount of foam in the beverage.

  • Patent number: 10660348
    Abstract: An appliance for producing frozen food products, such as ice cream or slush drinks, includes a cooling cylinder connected in a refrigeration circuit, the cooling cylinder including a thermally-conductive cylinder wall and end cap closing the distal end of the cylinder wall, the cylinder wall and end cap separating refrigerant on one side from product to be frozen on the other side. A divider member disposed adjacent the cylinder wall forms contiguous evaporator compartments spaced apart axially. Restrictor passages in the divider member permit communication between contiguous compartments and refrigerant first enters the first-cooled evaporator compartment at one of the axial ends and flows in series between the evaporator compartments. For fast, efficient freezing of small batches, the product to be frozen is either driven by the auger, or drains, toward the first-cooled evaporator compartment.

  • Publication number: 20160172952
    Abstract: A stator of a stepping motor comprises two magnetic field closed loops. Each magnetic field closed loop comprises a body as well as a main driving pole and an auxiliary driving pole. The main driving pole and the auxiliary driving pole are configured to assemble a coil. The two main driving poles and the two auxiliary driving poles cooperatively enclose to form a receiving hole for receiving a rotator, and an open space is formed between the two main driving poles and/or the two auxiliary driving poles.

  • Patent number: 8931401
    Abstract: A cooking appliance includes a base upon which a pot is supported, with a stirrer configured as a lid, for closing an open top of the pot. A tool coupled to a motorized drive of the stirrer extends downwardly into the pot. A heating element is coupled to the base and resiliently biased outwardly from the base to engage the base of the pot. A latch mechanism is provided for releasably connecting the pot to the base. The motorized drive includes a planetary gear set mounted coaxially with a pot axis, and a tool coupling is connected to a planet gear of the planetary gear set to drive the stirring tool in an orbital motion.

  • Publication number: 20130177687
    Abstract: A toasting appliance includes a pair of elongate radiant elements, and provides relative movement between the radiant elements and the foodstuff to be toasted, so as to traverse the foodstuff with the elements, or vice versa. For faster operating speed and improved efficiency, a control circuit receives a toasting-control signal and controls a switch to energise the elements only during a portion of the amplitude of relative displacement produced between the carriage and elements, the portion being defined by the toasting-control signal. Correct movement of the elements is monitored by a control circuit that de-energises the elements when, due to a fault, one of the elements and the carriage departs from a defined velocity profile.
