Definitions

  • the present invention relates to an induction cooker.
  • An induction cooker generally comprises glass top which includes one or more cooking zones each for inductively heating a ferromagnetic cooking utensil at the heating level that is respectively selected by the user and a user-interface for allowing the user to select for each heating zone the heating level from a range of heating levels.
  • WO2015096928(A1 ) discloses an induction cooker.
  • EP2876976 discloses another prior art induction cooker.
  • a problem with the prior art induction cooker is that the user cannot easily recognize the operational states of the cooking zones from the user-interface.
  • An objective of the present invention is to provide an induction cooker which solves the aforementioned problem of the prior art in a cost-effective way and which enables the user to easily and quickly obtain an improved overview of the operational states of the cooking zones.
  • the induction cooker of the present invention comprises one or more optical devices each adapted to project an image onto the circumferential wall of the cooking utensil that is placed on the respective cooking zone, wherein the image shows information which relates to the operational state of the respective cooking zone.
  • a major advantageous effect of the present invention is that the user can immediately recognize the operational state of each cooking zone from the image which is projected onto the respective cooking utensil. Thereby, the user can quickly ascertain whether the cooking zone is in the desired operational state and thus the food inside the coking utensil can be prevented from undercooking or overcooking.
  • Another major advantageous effect of the present invention is that the user can more easily and precisely operate the induction cooker by individually viewing the the images. Thereby, the complaints can be eliminated or reduced as much as possible.
  • optical devices can be used for illuminating the respective cooking utensils and/or for providing the user with useful information and instructions so as to interactively assist the user in cooking a particular recipe in accordance with the user-selection via the user-interface.
  • the image projected onto the circumferential wall of the cooking utensil shows the temperature of the respective cooking zone as sensed through the sensing unit and/or as accordingly set through the user-interface by way of selecting the heating level.
  • the image projected onto the circumferential wall of the cooking utensil additionally shows the current operating power of the respective cooking zone. This embodiment is particularly advantageous as the user can immediately see the current operating power of the cooking zone and correctly select the optimum heating level for the food being cooked.
  • the optical device is provided as an image projector such as an LCD projector or the like.
  • image projectors known to those skilled in the art may be alternatively used. These embodiments are particularly advantageous as a high quality image can be easily projected onto the circumferential wall of the cooking utensil.
  • the optical device has a plurality of laser diodes which are arranged to form one or more multiple segment displays that project the image onto the circumferential wall of the cooking utensil.
  • the optical device is arranged in close proximity to the respective cooking zone and either under the glass top or above the glass top.
  • the glass top is entirely or partly transparent so as to transmit the projected image.
  • the glass top may be opaque. The images are projected onto the circumferential wall of the cooking utensil that substantially faces the front side of the induction cooker.
  • the image projected onto the circumferential wall of the cooking utensil comprises signs, including symbols and/or words.
  • the image projected onto the circumferential wall of the cooking utensil comprises instructions to the user for a particular recipe that has been selected through the user-interface.
  • the induction cooker (1) comprises a glass top (2) which includes one or more cooking zones (3) each for inductively heating a cooking utensil (4) at the heating level that is respectively selected by the user, wherein each cooking zone (3) has one or more induction coils (not shown) and a user-interface (5) for allowing the user to select for each heating zone (3) the heating level from a range of heating levels ( Fig. 1 and Fig. 2 ).
  • the induction cooker (1) of the present invention further comprises one or more optical devices (6) each adapted to project an image (7) onto the circumferential wall (8) of the cooking utensil (4) that is placed on the respective cooking zone (3), wherein the image (7) shows information which relates to the operational state of the respective cooking zone (3) ( Fig. 1 ).
  • the optical device (6) includes an imaging unit (6a) which generates and projects the image (7) and a control unit (6b) which controls the imaging unit (6a) ( Fig. 2 ).
  • the image (7) shows the temperature of the respective cooking zone (3) ( Fig. 1 ).
  • each cooking zone (3) has a sensing unit (not shown) which is adapted to sense the temperature of the cooking zone (3).
  • the temperatures of the cooking zones (3) as sensed are sent to the control unit (6b) of the optical device (6).
  • the sensing unit is further adapted to sense the temperature of the induction coil of the respective cooking zone (3) by means of an NTC temperature sensor (not shown) or the like.
  • the temperatures of the cooking zones (3) which respectively correspond to the heating levels as selected by the user are sent to the control units (6b) of the optical devices (6).
  • the image (7) shows the current operating power of the respective cooking zone (3).
  • the current operating powers of the cooking zones (3) which respectively correspond to the heating levels as selected by the user are sent to the control units (6b) of the optical devices (6).
  • each optical device (6) comprises a plurality of laser diodes (9) which are arranged to form at least a pair of seven segment displays (10).
  • the laser diodes (9) are mounted onto a printed circuit board (6c) ( Fig. 2 ).
  • each optical device (6) is arranged under the glass top (2) in close proximity to the respective cooking zone (3).
  • the glass top (2) is transparent so as to transmit the image (7) being projected ( Fig. 1 and Fig. 2 ).
  • a major advantageous effect of the present invention is that the user can immediately recognize the operational state of each cooking zone (3) from the image (7) which is projected onto the respective cooking utensil (4) ( Fig. 1 ). Thereby, the user can quickly ascertain whether the cooking zone (3) is in the desired operational state and thus the food inside the coking utensil (3) can be prevented from undercooking or overcooking.
  • Another major advantageous effect of the present invention is that the user can more easily and precisely operate the induction cooker (1) by individually viewing the the images. Thereby, the complaints can be eliminated or reduced as much as possible.
  • optical devices (6) can be used for illuminating the respective cooking utensils (3) and/or for providing the user with useful information and instructions so as to interactively assist the user in cooking a particular recipe in accordance with the user-selection via the user-interface (5).
