Definitions

  • the present invention refers to an induction hob comprising a body with at least one induction module arranged therein, and a flat glass or ceramic cover element provided for receiving a container to be heated and covering said body.
  • an induction module is fixed in a body of an induction hob by means of force fitted pins, screws, or similar connection, said induction module attached thereon.
  • Such a connection of the induction module and the body is rather complex and high-priced.
  • disassembling the induction module and the body also represents considerable complexity. A weakening of the connection between said module and said body often takes place, in particular with multiple assembling and/or disassembling of the induction module and the body.
  • folds are used with known induction hobs provided for attaching the induction module thereon.
  • the stiffness of the fold represents a considerable problem, since the fold may become loosen due to the forces during transportation resulting in dislocation of the induction module from desired position.
  • a bottom of a body of a induction hob is formed with a plurality of receptacles provided for cooperation with supports of each induction module.
  • Each support is either formed as a deformable support or is comprised of a deformable element. Said deformability of the plurality of the supports provides for the induction module is reliably and firmly pressed against a cover element.
  • said support comprises a deformable element
  • said support is formed at the free end thereof facing said bottom of the body with a cavity for accommodation of the deformable element.
  • said receptacles are formed as fittings attached to the bottom of the body, such as glued, welded or screwed fittings for example. Yet further is provided that the receptacles are formed as convexities or concavities in the bottom of the body, said receptacles created by a deep-drawing process. Yet further is provided that said receptacles are formed as integral parts of the bottom of the body and, respectively, as folds in the bottom of the body created by a punching and bending process for example. Obviously, an arbitrary combination of said embodiments is possible.
  • Said receptacle comprises at least one tongue folded approximately perpendicularly with regard to the bottom of the body.
  • said receptacle can comprise a plurality of tongues arranged in circle on the bottom of the body so that they either envelope the outer perimeter of the support and/or are enveloped by the inner perimeter of said cavity of the support.
  • At least one said receptacle comprises a tongue or a plurality of tongues which is/are punched and/or bent in various directions, thus lowering the load of the tongues during assembly, transport and use of the hob.
  • An induction hob comprises a body 1 with at least one induction module 2 arranged therein 2, said body 1 being closed, for instance, by a glass or a ceramic flat cover element 3 provided for receiving a container to be heated.
  • the induction module 2 arranged in the body 1 is tightly pressed against said cover element 3, and cooperates, on the other hand, by means of a plurality of supports 4 with a bottom 1' of the body 1, said bottom 1' averted from the cover element 3.
  • Each support 4 is either formed as a deformable support, or it comprises a deformable element 5. Said deformabiliy of the plurality of supports 4 provides for a reliable and firm pressing of the induction module 2 against the cover element 3.
  • said deformable element 5 is selected as a helical compression spring.
  • the support 4 comprises a deformable element 5
  • the support 4 is formed at the free end thereof facing the bottom 1' of the body 1 with a cavity 4' to accommodate the deformable element 5.
  • the depth of the cavity 4' that is the extension of the cavity 4' in direction from said free end of the support 4 towards the end of the support 4 fixed to the induction module 2, is shorter than the length of said deformable element 5, thus providing continuous action of the elastic force pressing the induction module 2 against the cover element 3.
  • said bottom 1' is formed with a plurality of receptacles 6 configured to accommodate supports 4 and to cooperate therewith.
  • Said receptacles 6 are formed as fittings attached to the bottom 1', such as glued, welded or screwed fittings for instance.
  • the receptacles 6 are formed as convexities or concavities in the bottom 1' created by a deep-draw process.
  • said receptacles 6 are formed as integral parts of the bottom 1' and, respectively, as folds in the bottom 1', created by punching and bending process, for example.
  • an arbitrary combination of said embodiments of the receptacle2 6 is possible.
  • Fig. 2 , 3, 4 and 5 show an embodiment of the receptacle 6 which is created in the bottom 1' of the body 1 by punching and bending process.
  • the receptacle 6 comprises at least one tongue 7 bent approximately perpendicularly with regard to the bottom 1' of the body 1, said tongue 7 being formed in its cross-section, where the sectional plane extends in parallel with the bottom 1' of the body 1, in a manner that it resembles an approximate shape of the letter U or V or similar, and in a manner that it is adapted either to the outside diameter and, respectively, the inner diameter of said cavity 4' of the support 4 or to the inner diameter of the helical compression spring 5.
  • Such a structure of the tongue 7 also enables additional stiffness of the tongue 7.
  • each support 4 cooperates with at least one of the tongues 7, wherein the tongue 7 serves both for guiding the compression spring and, respectively, the deformable element 5, and for positioning of the induction module 2.
  • the edges of the free end of the tongue 7 are formed with a fillet or a chamfer in order to facilitate the accommodation of the support 4.
  • Fig. 6 and 7 shows an embodiment of the receptacle 6 formed with a plurality of tongues 7, which are formed in the bottom 1' of the body 1 by punching and bending process.
  • Said tongues 7 of the receptacle 6 are arranged in circle so that they either envelope the outer perimeter of the support 4 and/or are enveloped by the inner perimeter of said cavity 4' of the support 4, when the support 4 is inserted into the receptacle 6 and, respectively, is placed onto the tongues 7. It is provided for according to the preferred embodiment that the connection between each support 4 and each receptacle 6 is formed as a tight elastic connection.
