Problems solved by technology

However, reducing the thickness of the microcrystalline panel weakens the panel's mechanical strength and makes it impossible to produce hobs in wide or professional sizes, not even in standard sizes
[0007] In addition, because the heating temperature may be very high, reducing the thickness of the microcrystalline panel and the insulator will not guarantee that the induction coil will still have good thermal insulation properties
[0008] Another disadvantage of this solution is that it is difficult to accurately measure the temperature of the container, especially because the thickness of the panels affects
However, this solution is not suitable for containers with uneven bottoms, because when the bottom of the container is deformed and cannot be in direct contact with the supporting surface, the sensitive element cannot accurately measure its temperature
Also, punching a via hole in a microcrystalline panel weakens the panel's mechanical strength and creates sealing issues that are expensive to fix
[0011] As long as the measurement system used can take into account the factors that cause inaccurate measurements such as container deformation and the thickness of the microcrystalline panel, it is still possible to improve the measurement accuracy of temperature, but this measurement system is complex and expensive
[0012] Furthermore, although microcrystalline panels have the advantage of heat resistance, they are expensive and very sensitive to impact and abrasion

Embodiment Construction

[0082] image 3 , 4 , 5, the induction heating device 1 includes a panel 10 . The face plate 10 has a recess defining a heating zone 11 . A support 15 is placed inside the groove for stably placing the container 3 in the heating zone. The support has a section 150 which contacts the edge of the groove on the panel 10 . A non-magnetic, electrically insulating plate 14 is placed over the groove, extending over the entire surface of the groove, forming the heating zone 11 . The stand rests on a non-magnetic, electrically insulating plate 14 . Encapsulation of panels, supports and non-magnetic electrical insulation panels can be achieved by gaskets or grooves through the chamfered outer edge. There is a groove on the non-magnetic electrical insulating plate 14, and a temperature sensor 4 is arranged in the groove, and its sensing part is in contact with the support 15. An induction coil 2 is placed under the panel 10 and directly opposite to the heating zone 11 .

Abstract

The invention relates to a device (1) for induction heating, including at least one base (10) having at least one heating area (11), and at least one inductor (2) arranged under the base (10) opposite the heating area (11). The base (10) includes a recess delimiting the heating area (11), and inside which a stand (15) is arranged that partially covers said heating area (11) and which is partially rigidly connected to the base (10), wherein said support (15) is capable of supporting a container (3) so as to keep said container (3) above the recess.

Description

technical field [0001] The present invention relates to the field of induction cooking equipment, generally referred to as "induction panels" or "induction hobs". Background technique [0002] refer to figure 1 and figure 2 Generally speaking, the induction heating device 1 includes a panel 10 with a flat surface, usually made of high temperature resistant non-magnetic electrical insulating material, such as microceramic glass (vitroceramic glass), also known as microceramic glass (vitroceramic) , for supporting a container 3 suitable for induction cooking. The panel 10 has a heating area 11 (or a cooking pan), under which an induction coil 2 (or an inductor) is arranged, and is installed in an outer frame (or frame) 13 made of a thin steel plate to support the panel 10 . The induction coil 2 is powered by an alternating current generator, which generates a changing electromagnetic field inside the container 3 placed in the heating zone 11. The container 3 is preferably ...
