  • Induction cooking systems have been known for many years but have gained popularity recently due to their many advantages over other types of cooking systems. Like a traditional electric stove, an induction stove uses electricity to generate heat. However, instead of heating a resistive element (such as a coil of metal) by passing electric current through it, an induction stove generates an oscillating magnetic field that causes the cooking vessel itself to be heated.

  • an induction stove instead of heating a resistive element (such as a coil of metal) by passing electric current through it, an induction stove generates an oscillating magnetic field that causes the cooking vessel itself to be heated.
  • a wire coil located beneath the cook-top receives an alternating electrical current, and thereby creates an oscillating magnetic field.
  • the oscillating magnetic field causes the
  • the ferromagnetic material to heat up.
  • the ferromagnetic material is heated by means of magnetic hysteresis loss in the ferromagnetic material as well as by eddy currents created in the ferromagnetic material (which generate heat due to the electrical resistance of the material).
  • the mechanisms by which an induction stove generates heat in a cooking vessel are well known to those of skill in the art.
  • no portion of the cook-top itself is directly heated by the induction heating element, unlike in a traditional electric stove, where a circular heating element is heated in order to heat a cooking vessel that is placed thereon.

  • the cook top 14 is positioned in a horizontal orientation and has an upper surface 16 and a lower surface 18. A thickness is defined between the upper and lower surfaces.
  • the cook top is fabricated of any material suitable for an induction stove cook-top, including ceramic, glass, high density thermoplastics, non-ferromagnetic metals (such as aluminum), etc. In some embodiments, the cook top is formed of a thermally insulating material.
  • the cook top 14 includes control apertures 24, 26, 28, which accommodate controls 50, 52, 54.

In other embodiments, the thickness of the isolation blocks varies from the thickness of the cooking plate by plus or minus 25 percent. In still other embodiments, the thickness is chosen based on the particular system design and the material selected for the isolation blocks.

  • Beneath each indentation 20, 22 is a circular induction element or coil. Shown in Figure 2 is a first circular induction element 42, which is secured to the lower surface of the cook top 14 beneath the first indentation 20.
  • a second circular induction element is secured to the lower surface of the cook top 14 beneath the second indentation, but is not shown in the figures.
  • Each induction element has a coil of copper wire adapted to support an oscillating potential of appropriate volts at an appropriate frequency. As described above, the induction coils are controlled by the controls 50 and 52 by the user of the system to increase or decrease the amount of heat generated in the cooking vessel.
  • a vibrator 46 is secured to the lower surface of the cook top 14.
  • the vibrator is located between the indentations 20, 22 and the induction elements.
  • the vibrator oscillates a mass in a horizontal plane, which imparts an oscillating, horizontal movement to the cook-top 14.
  • the cook-top 14 is able to vibrate because of the elasticity of the isolation blocks 38.
  • the amplitude and frequency of the vibration is chosen according to the particular design characteristics of the overall system.

  • One example of a suitable vibrating device is the combination of an electric motor having a crank attached to its driveshaft, where the crank includes an off-center mass. Rotation of the crank by the motor causes an oscillating force in the plane perpendicular to the driveshaft.

  • the vessel contains food to be cooked, which is accomplished on account of the vessel including at least some portion or element of a suitable ferromagnetic material. On account of this material, potential in the induction element is creates heat within the cooking vessel.
  • the coupling of the vibrator 46 to the cooking vessel 58 is enhanced by the use of the isolation blocks 38 and the pad 62.
  • Each adds an amount of mobility to the system which increases the ability of the vibrator to impart motion to the food in the cooking vessel, while reducing or eliminating the possibility that the cooking vessel will slide relative to and away from the induction cooking zone.
  • the material of the pad is chosen so that the friction force between the pad and the cooking vessel is sufficient to prevent unwanted sliding of the vessel at all, including during vibration cooking.

  • the cartridge has an open top, a closed bottom, and a side wall.
  • the cartridge also includes a lower layer 572 of material positioned upon the bottom of the container, an upper layer 576 of expandable material positioned above a cavity 574 holding popcorn 575, and an intermediate layer 573 located between the popcorn and the lower layer fabricated of a ferromagnetic material.
  • the intermediate layer interacts with and generates heat in response to energizing of the induction element 542.
  • the plan view of Figure 14 shows the expandable upper layer 576.
  • the layer 576 is a layer of folded aluminum foil that gradually unfolds as the popcorn in the cavity 574 pops and increases in volume.
  • the cartridge 538 is adapted to function as a package in which the unpopped popcorn is to be sold, as a vessel for the popping of the popcorn, and also as a container for serving the popcorn to be eaten.
  • the present invention is designed to vibrate a stove top, cookware or small appliance, i.e. crock pot, rice cooker, popcorn maker, etc. while cooking.
  • the stove top, cookware, small appliance can be made of any material, i.e. glass, metal, ceramic, composite, etc.
  • the invention will eliminate the need for stirring in some cooking applications by keeping the contents moving.
  • the invention will prevent food from sticking and burning in the cookware or small appliance by keeping the food moving.

Abstract

L'invention concerne un système de cuisson qui utilise des vibrations pour faciliter la préparation des aliments et améliorer la qualité du produit fini. Le système fait appel à un dispositif vibrant couplé à un récipient de cuisson comportant une semelle et/ou des blocs isolants disposés entre l'élément vibrant et le récipient. Ce système de cuisson peut être adapté préparer des aliments spécifiques suivant des quantités déterminées tels que du popcorn dans des récipients pré-emballés.
