Induction hot plate comprising heating regions having a reconfigurable structure, and method for increasing the maximum power of said heating regions
View Patent ↗An induction hot plate including a plurality of heating regions with a reconfigurable structure. The hot plate includes at least two power modules, each supplying electrical power to at least one first and one second induction heating element. The maximum power to each of the regions can be increased by supplying electrical power from both power modules to only the first or the second induction heating element.
1. An induction hot plate, comprising:
at least one first induction heating element having at least a first heating region for a cooking container;
at least one second induction heating element having at least a second heating region for a cooking container;
at least two power modules, each of which supplies electrical power to at least said first and said second induction heating element; and
said two power modules both supplying electrical power to only one of said first and said second induction heating elements to temporarily increase the electrical power to a maximum to said one induction heating element.
2. The induction hot plate according to claim 1 , including said first induction heating element including a pair of induction heating elements forming a pair of heating regions which together form a common heating region and said two power modules both supplying electrical power to said first induction heating element by supplying electrical power to said pair of induction heating elements to temporarily increase the electrical power to a maximum to said first induction heating element.
3. The induction hot plate according to claim 2 , including said common heating region is constructed as a two-circuit heating region with an outer concentric heating region and an inner concentric heating region, each associated with one of said pair of induction heating elements.
4. The induction hot plate according to claim 2 , including a pot recognition device which registers the size of a base surface of a cooking container placed on said common heating region.
5. The induction hot plate according to claim 4 , including said two power modules both supplying electrical power to said pair of induction heating elements only when said cooking container base surface exceeds a predetermined size.
6. The induction hot plate according to claim 5 , including only one of said two power modules supplying electrical power to said pair of induction heating elements when said cooking container base surface is less than said predetermined size.
7. The induction hot plate according to claim 1 , including said second induction heating element including a pair of separate induction heating elements forming a separate pair of heating regions and said two power modules both supplying electrical power to one of said separate induction heating elements to temporarily increase the electrical power to a maximum to said separate induction heating element.
8. A method for increasing the maximum heating power for one heating region of an induction hot plate including at least two separate heating regions, the two separate heating regions formed by at least one first induction heating element having at least a first heating region for a cooking container and at least one second induction heating element having at least a second heating region for a cooking container at least two power modules, each of which supplies electrical power to at least said first and said second induction heating element, comprising:
supplying electrical power to only one of said first and said second induction heating elements from both of said two power modules to temporarily increase the electrical power to a maximum heating power to said one induction heating element.
9. The method according to claim 8 , including said first induction heating element including a pair of induction heating elements forming a pair of heating regions which together form a common heating region and supplying electrical power to said first induction heating element by supplying electrical power from both of said two power modules to said pair of induction heating elements to temporarily increase the electrical power to a maximum to said first induction heating element.
10. The method according to claim 9 , including constructing said common heating region as a two-circuit heating region with an outer concentric heating region and an inner concentric heating region, each associated with one of said pair of induction heating elements.
11. The method according to claim 9 , including measuring the size of a base surface of a cooking container placed on said common heating region.
12. The method according to claim 11 , including supplying electrical power from both of said two power modules to said pair of induction heating elements only when said cooking container base surface exceeds a predetermined size.
13. The method according to claim 11 , including supplying electrical power from only one of said two power modules to said pair of induction heating elements when said cooking container base surface is less than said predetermined size.
14. The method according to claim 8 , including forming said second induction heating element from a pair of separate induction heating elements, each forming a separate pair of heating regions and supplying electrical power from both of said two power modules to one of said separate induction heating elements to temporarily increase the electrical power to a maximum to said separate induction heating element.
