present invention.
[0074] The induction coil 24 is arranged above the coil carrier 26.
The connecting element 10 is arranged between the induction coil 24
and the coil carrier 26. The connecting element 10 penetrates the
induction coil 24, wherein the snap-fit portion 12 of said
connecting element 10 is arranged above the induction coil 24. The
spring portion 14 of the connecting element 10 is arranged between
the induction coil 24 and the coil carrier 26. The groove 16 of the
connecting element 10 engages with the cut-out in the induction
coil 24. For example, the cut-out of the induction coil 24 is
formed in an aluminium disk of said induction coil 24. The spring
portion 14 of the connecting element 10 is supported by the coil
carrier 26.
[0075] FIG. 15 illustrates a schematic perspective sectional view
of the connecting element 10 interconnected between the induction
coil 24 and the coil carrier 26 according to the first embodiment
of the present invention. At least one connecting element 10 is
provided for connecting the induction coil 24 to the coil carrier
26. For example, three connecting elements 10 are provided for
connecting the induction coil 24 to the coil carrier 26.
[0076] The snap-fit portion 12 of the connecting element 10 is
arranged above the induction coil 24, while the spring portion 14
of the connecting element 10 is arranged beneath said induction
coil 24 and above the coil carrier 26. The groove 16 of the
connecting element 10 engages with the cut-out in the induction
coil 24. The spring element 14 of the connecting element 10 is
supported by the coil carrier 26.
[0077] A bent sheet metal finger 28 of the coil carrier 26
penetrates the through hole 20 of the connecting element 10. A
resulting cutting 30 from preparing the bent sheet metal finger 28
remains in the coil carrier 26. Said cutting 30 is arranged beneath
the spring element 14 of the induction coil 24. The bent sheet
metal finger 28 of the coil carrier 26 extends vertically upwards.
The connection between the bent sheet metal finger 28 and the
through hole 20 effects that the connecting element 10 cannot be
displaced parallel to the coil carrier 26.
[0078] The snap-fit portion 12 of the connecting element 10 and the
cut-out in the induction coil 24 form a snap-in mechanism, so that
the connecting element 10 and the induction coil 24 are fixed to
each other. The connection of the bent sheet metal finger 28 and
the through hole 20 guarantee the correct placement of the
induction coil 24 and the connecting element 10 on the coil carrier
26. Further, the connecting element 10 acts as a spacer and avoids
that the metallic induction coil 24 and the metallic coil carrier
26 enter in contact. Moreover, the spring portion 14 of the
connecting element 10 pushes the induction coil 24 towards against
a cooking panel arranged on the top side of the induction cooking
hob.
[0079] The connecting elements 10 of the first and second
embodiments do not require any steel spring elements because of the
spring portion 14. The connecting elements 10 of the first and
second embodiments do not require any space beneath the coil
carrier 26. The connecting elements 10 of the first and second
embodiments may be for already existing induction coils 24 and coil
carriers 26.
[0080] FIG. 16 illustrates a schematic perspective view of the
connecting element 10 interconnected between the induction coil 24
and the coil carrier 26 according to the third embodiment of the
present invention.
[0081] The induction coil 24 is arranged above the coil carrier 26.
The connecting element 10 is fastened at the induction coil 24 and
at the coil carrier 26. The connecting element 10 is penetrated in
the induction coil 24, wherein the snap-fit portion 12 of said
connecting element 10 is arranged above the induction coil 24. The
spring portion 14 of the connecting element 10 is arranged between
the induction coil 24 and the coil carrier 26. The grooves 16 of
the connecting element 10 engage with the cut-out in the induction
coil 24. For example, the cut-out of the induction coil 24 is
formed in an aluminium disk of said induction coil 24. The distal
ends of the wings of the spring portion 14 are supported by the
coil carrier 26. The further snap-fit portion 18 of the connecting
element 10 penetrates the cut-out 32 in the coil carrier 26.
[0082] FIG. 17 illustrates a schematic perspective sectional view
of the connecting element 10 interconnected between the induction
coil 24 and the coil carrier 26 according to the third embodiment
of the present invention. At least one connecting element 10 is
provided for connecting the induction coil 24 to the coil carrier
26. For example, three connecting elements 10 are provided for
connecting the induction coil 24 to the coil carrier 26.
[0083] The connecting element 10 is fastened at the induction coil
24 and at the coil carrier 26. The snap-fit portion 12 of said
connecting element 10 is fastened above the induction coil 24,
while the spring portion 14 of the connecting element 10 is
arranged between the induction coil 24 and the coil carrier 26. The
grooves 16 of the connecting element 10 engage with the cut-out in
the induction coil 24. The distal ends of the wings of the spring
portion 14 are supported by the coil carrier 26. The further
snap-fit portion 18 of the connecting element 10 penetrates the
cut-out 32 in the coil carrier 26.
[0084] The connecting elements 10 of the third to fifth embodiments
allow the fastening of said connecting elements 10 on the coil
carrier 26 without the bent sheet metal fingers 28. The cut-out 32
in the coil carrier 26 is sufficient for fixing the connecting
element 10 by the further snap-fit portion 18. The concept of the
cut-outs 32 in the coil carrier 26 allows a modular coil carrier
26. A plurality of arrangements of cut-out 32 in the coil carrier
26 allows that one coil carrier 26 is provided for different
induction cooking hobs.
[0085] The snap-fit portion 12 and the further snap-fit portion 18
of the connecting element 10 allow an automatic assembling of the
induction coil 24 on the coil carrier 26 by an assembling line. The
connecting element 10 with the snap-fit portion 12 and the further
snap-fit portion 18 allows the assembling of the induction coil 24
on the coil carrier 26 by a robot. The snap-fit portion 12 and the
cut-out in the induction coil 24 form the snap-in mechanism between
the induction coil 24 and the connecting element 10, while the
further snap-fit portion 18 and the cut-out 32 in the coil carrier
26 form a snap-in mechanism between the coil carrier 26 and the
connecting element 10.
[0086] Although illustrative embodiments of the present invention
have been described herein with reference to the accompanying
drawings, it is to be understood that the present invention is not
limited to those precise embodiment, and that various other changes
and modifications may be affected therein by one skilled in the art
without departing from the scope or spirit of the invention. All
such changes and modifications are intended to be included within
the scope of the invention as defined by the appended claims.
