Definitions

This invention concerns improvements relating to electric heating
thick film type comprising a substrate, commonly formed of stainless steel,
the substrate may be formed on an electrically-insulating
electrically-insulating layer may be provided over the resistance heating track
Thick film heating elements are employed in
immersion heating element of metal sheathed construction has aesthetic
a further layer of glass may then be provided over the
the domed thick film heating element onto the planar surface.
the joining process may be the same as or similar to any of the
Blitzkocher type elements i.e. impact pressure bonding, welding or brazing
dispersion layer to the vessel may be done first, for example by impact
the heating element may be induction brazed separately, giving the opportunity of inspecting the quality of the vessel/dispersion layer joint.
Vents could be left in the part of the dispersion layer which extends beyond
the heating element to allow the escape of flux and fumes generated during
the assembly is desirably pressed
Figure 1 is a schematic side elevation view of a thick film heating
FIGS. 2 A and 2B show alternative constructions of the peripheral
Figure 3 is a plan elevation view of the thick film heating element of
the illustrated embodiment comprises a thick film heating element 1
Figures 2A and 2B are, respectively, intended to provide a
the dispersion layer will spread the
heating element of an effective diameter of 80mm.
the heater track power density is
the heater can be reduced still further
a disc of 77mm diameter has half the area of one of 110mm,
the thin substrate becomes possible because of the support
the vessel wall which is preferably formed of a 300 series
the heating surface is not more than that of a conventionally made thick
the complete heating element sandwich can be made as an "Easifix"
plastic securing ring as was developed for the Millennium kettle. Examples of
hotplate element which may have a raised heating surface surrounded by a
the diameter of the element four times as many may be printed and processed
the small diameter element has an additional operational advantage
the dispersion layer will ensure that, as liquid boils away, the exposed area of
the heater is cooled to some extent by the remaining liquid until a protector
any thermal protector will tend to cover a larger
sheathed heating element is secured to a heat transfer plate which in turn is
thermal conductivity of the ceramic substrate and are only suitable for low
