Definitions

  • the present invention generally relates to induction cooktops and in particular to modular induction coil arrangements having integrated display devices included therein.
  • a trend with home appliances is to make them smart, namely, digitally connected, so as to offer cooking assistance and information feedback to the user, as well as provide for new options for designs along with an overall improvement of the customer experience.
  • certain home appliances have started to include a variety of individual features which use light from built-in light sources to visually communicate with the user useful information including cooking parameters, cooking recipes and the like.
  • particular arrangements of the light sources have been shown to increase the aesthetic appeal and design of a respective home appliance and have therefore become a consideration for the smart home appliance designer and engineer with respect to how to increase the appeal of their design and end-product.
  • induction cooktops are gaining in popularity worldwide.
  • induction cooking is a two-part system.
  • the first part is a coil of wire, such as a copper wire, particularly coiled such that when an electric current is passed through the coil, it creates an electromagnetic field of energy below the cooktop surface, at a cooking zone of the cooktop, which radiates upwards and outwards from below the surface.
  • the second part is a magnetic cooking utensil appropriately configured with a sufficient amount of magnetic content, such as iron and the like, applied along the bottom of the cooking utensil, so as to work be detectable by the induction cooktop and/or at least interact with the electromagnetic field generated by the induction coil in order to undertake the cooking process.
  • the induction cooktop heats up the cooking utensil via the excitation of molecules within the appropriate cooking utensil by the electromagnetic field, the friction created by the excitation resulting in heat generation in the cooking utensil. Accordingly, the induction coil directly heats up the cooking utensil.
  • a traditional heat source in a cooking zone must generate a sufficient amount of heat to pass or transfer through the cooktop surface, typically ceramic, to reach the cooking utensil and only then heat up the cooking utensil.
  • induction cooktops results in faster cooking times, faster control of heat generation/reduction and a lack of dangerous/intense heat generation at the cooktop surface of the cooking zone.
  • a traditional heat generating cooking zone may produce upwards of 200 degrees Celsius for boiling water, such being intensely dangerous to the human touch.
  • the typical induction cooktop cooking zone produces about 40 degrees Celsius, arising mostly arising from heat back down to the surface from the utensil, such not being intensely dangerous to the human touch.
  • Certain induction cooktops may include particular forms of illumination taking the form of form of light emitting diodes (LED) arranged below the cooktop surface and configured so as to emit a particular radiation of light that is transmissive by the cooktop surface and visible to the cooktop user.
  • LED light emitting diodes

  • the teachings provided herein are directed towards a particular type of display having certain physical wear-resistant features.
  • DE102012219040A1 discloses a display device for a glass ceramic hob having LED backlighting arranged underneath a display surface, the display being thermally connected with a surface of an insulating and non-transparent metal plate.
  • EP0990855B1 discloses a hob plate having a number of difference cooking zones with individual integrated timing controls facilitating the programming of certain time-based functions for the respective zone.
  • the controls are accessible via certain electronically insulated operating elements with capacitive, inductive, or piezoelectric sensor functionality and a display element for indicating the selected time.
  • EP25887166A2 and US 20130098351A1 are directed to a cooking apparatus having a hob plate with a heating device arranged beneath it for cooking a vessel placed on the plate.
  • An optical display device for displaying temperature is also provided below the hob plate proximate to and/or between it and the heating device.
  • the display device comprises thermochromic color or material, namely a material known to change color in response to a particular change in temperature, applied on a separate carrier, and otherwise visible from above the cooktop surface.
  • US2007096631A1 is directed to a particular configuration for a flat panel display with an insulating substrate, the panel being directed towards minimizing an inflow of ambient oxygen and moisture.
  • a heat transfer member is also provided between a first and at least one of the insulating substrates and a cover substrate. Application of the panel to a kitchen environment, and in particular to an induction stovetop or hob, is absent.
  • WO2019201590A1 is directed to a panel for a cooking hob having a glass layer and a reactive layer responsive to electric, electromagnetic and/or thermic parameters, the reactive layer acting as a visual indicator.
  • EP3177108A1 is directed to light elements arranged below an induction cooktop surface, the arrangement including air vents through which air is pumped in a close loop in order to dissipate heat buildup below the surface.
