  • Patent number: 10595366
    Abstract: In a method for operating an induction hob including a controller and including a cooking point including an induction heating coil, a relationship between a cooking vessel temperature and a heating power of the induction heating coil is stored in the controller as area power which results in a constant cooking vessel temperature during long-term operation. By monitoring whether the cooking vessel temperature remains constant, increases or drops when a first relatively low heating power is set after a heating time at a high heating power, it is possible to set a target temperature, which corresponds to the first relatively low heating power, for frying processes.

  • Patent number: 8796591
    Abstract: An apparatus for warming a container, the apparatus including a holder having an inner wall, an outer wall, and an insulation layer between the inner and outer walls, wherein the inner wall defines a first volume having a size and shape for receiving at least a portion of the container, and wherein the holder defines a second volume. The apparatus can also include a solution and an activation disk positioned within the second volume and in contact with the solution, wherein the solution and activation disk are made from materials such that a force applied to the activation disk causes the solution to undergo a chemical reaction that generates heat for warming the container in the first volume. Furthermore, the apparatus can include a disk actuator for applying the force to the activation disk, and elastic bands to increase thermal contact between the container and the solution.

  • Publication number: 20140197153
    Abstract: Apparatus and methods for heating of one or more substrates with a plurality of independently controllable heating zones. Pressurized air is provided to each of a plurality of independently controlled heater blocks each including a heating element. The pressurized air is heated in the heater blocks and discharged towards one or more regions of the one or more substrates. The amount of power provided to the heating element in one of the heating blocks may be adjusted relative to the amount of power provided to the heating element in another of the heating blocks. The temperature of one heating zone may thereby be adjusted relative to other heating zones so that the temperature of different heating zones for the one or more substrates may be independently controlled. Heated air may be recovered from the heating zones and recycled. The pressurized air may be preheated by passing through a lift plate.

  • Patent number: 8761950
    Abstract: A power control device includes a priority setting section capable of setting a use priority of a home appliance connected wirelessly or via cable or an adapter connected to the home appliance. The home appliance or the adaptor connected to the home appliance operates within the usable power of a result of the inquiry to the power control device. When there is no excess in usable power over the required power in the inquiry, the power control device reduces the power of a device having a lower priority than the device which has transmitted the inquiry in order to use the device with the higher priority.

  • Patent number: 8759723
    Abstract: Systems and methods for low voltage detection for a heat pump water heater are disclosed. A current sensor can be used to monitor current supplied to a inductive load, such as a compressor or evaporator fan, of the heat pump water heater. The current sensor can be coupled to a controller which receives and processes information from the current sensor to determine whether a low voltage condition of the heat pump water heater has occurred. An alert can be provided to an installer/user of the heat pump water heater that a low voltage condition has occurred. The controller can also disconnect the heat pump water heater from the power source to prevent damage to the heat pump water heater.
