Definitions

  • the present invention relates to the field of cooking appliances and more particularly the field of domestic or professional cooking appliances adapted for heating WOK-type spherical kitchen containers used in Chinese cuisine.
  • FIG. figure 1 An apparatus of the state of the art and comprising an induction heated WOK type hearth is shown in FIG. figure 1 .
  • One or more WOK type hearths may be present on a multi-zone cooktop.
  • the cooking chamber (a) of the figure 1 consists of a spherical inductor (b) formed of turns wound around the underside of a spherical cap-shaped support (c) and forming a cavity in the flat surface (d) of the stove, generally a glass-ceramic support or made of electrical insulating material such as composite, tempered glass, etc.
  • An induction heating vessel (e) of the pan bottom type is placed in the recess of the stove.
  • the inductor (b) is connected to an electronic induction generator (f) whose voltage is controlled by a joystick (g) or by an electronic keyboard, or any other means of control.
  • the applicant therefore had the idea of proposing an accessory to be combined with a WOK-type fireplace that would heat all types of flat-bottom or spherical utensils, in order to reduce the clutter in the kitchen, and in order to decrease the cost of the equipment for the user.
  • the invention consists of an interface module characterized in that it is externally formed with a concave cap-shaped lower face adapted to be placed in a convex spherical bowl of a container support plate provided on the top of a cooking appliance for example a stove or a multi-burner hob, and a flat upper surface in the form of a circular plate or the like, the cap and the plate being integral with each other.
  • the module comprises a heating element electrically connected to a spherical induction coil (11) whose turns are wound in contact with or in the vicinity of the cap (8) and inside thereof.
  • the invention also relates to an assembly that combines a hob and an accessory formed of said module.
  • the apparatus (1) shown in a nonlimiting figure 2 , consists of a conventional (2) bowl warmer (2) for WOK and an accessory or removable interface module (4) which, when positioned in the dish (3) of the stove ( 2), allows to use it to heat flat-bottomed containers.
  • the stove (2) comprises a control handle (5) controlling a generator (6) which feeds a spherical coil (7) wound on the underside of the bowl (3), and represented diagrammatically by way of example in the figure 5 .
  • the interface module (4) is formed externally with a lower face (8) in the form of a concave cap, capable of being placed in the convex spherical bowl (3) of the stove, and of a planar upper surface (9), in circular plate shape or other, the cap (8) and the plate (9) being fixed to each other by any fastening means (16).
  • a container (20) placed on the plate (9) is heated by a heating element (10) which may be of the radiant type or of the induction type (flat coil called inductor) and placed under the plate (9).
  • a heating element (10) which may be of the radiant type or of the induction type (flat coil called inductor) and placed under the plate (9).
  • An insulating means (17) is provided between the plate and the heating element and a ferrite magnetic element (18) under the heating element.
  • the heating element (10) is electrically connected to a spherical induction coil (11) whose turns are wound in contact with or in the vicinity of the cap (8) and inside thereof.
  • the two spherical coils (7) and (11) operate as a transformer whose primary winding is the coil (7) and the secondary winding the coil (11).
  • the coil (11) produces an electrical voltage between the two outputs (12) and (13) and electrically supplies the heating element (10) (radiant or inductor).
  • the figure 5 represents the circuit diagram of the interface module.
  • the interface module described above is particularly advantageous because it makes it possible to transform the initial stove into a flat stove without the need for an electrical connection. It can be declined according to different heating modes, the heating element (10) to be flat and held under the plate (9) by any suitable fixing means (14) for example as on the figure 2 by means of a plate (15) insulated and itself maintained by the fixing means (16) of the module. As an alternative embodiment the parts (8) and (9) of the module can be welded.
  • the principle of the adaptation module can be used for one or more less sophisticated variants.
  • the coil (11) can be removed and the heating element (10) fed directly by a power cord connected to the mains or to a socket provided on the stove.
  • the radius of the sphere portion forming the cap (8) is at most substantially the same as that of the bowl (3) and that the height of the interface module is greater than or equal to the depth of said bowl (3).
  • the plate (9) bears on the vessel support plate (19) of the stove, directly or via feet.
  • the figure 3 a module whose upper plate (9) is circular, the module (4) being surrounded continuously or discontinuously by a circular support maintained at its upper periphery by a bonding (21) or the like, and a horizontal return (22) rests by gravity on the flat support (19) .
  • a module according to the invention can be purchased alone by a user to be combined with a fireplace type WOK stove or cooktop available to the buyer. It can also be offered for sale at the same time as a stove or a hob as a removable accessory, regardless of how it is heated.
