This optical sensor is an infrared transmitter, an infrared receiver, or a transmitter / receiver complex. As such, the optical sensor can generate or receive one or more light beams at infrared wavelengths. This optical sensor is disposed in the home appliance 1 or the cooking container. The optical sensor is arranged perpendicular to the bottom of the household appliance 1 or the bottom of the cooking container so that the emitted light beam or rays 10 are transmitted perpendicular to the bottom of the household appliance 1 or the bottom of the cooking container. Established.

  In addition to being able to be heated, the home appliance 1 or the cooking container includes a power-receiving-side inductor 6 that recovers energy and supplies power to an auxiliary function of heating. The first optical device 4 is disposed in the middle of the power receiving side inductor 6. “Arranged in the middle” means that the first optical device 4 is arranged at the center of the circle when the power-receiving-side inductor 6 is circular, for example. In general, when the power-receiving inductor 6 has some shape or includes a plurality of power-receiving inductors 6, the first optical device 4 rotates the entire magnetic field formed by the one or more power-receiving inductors 6.

  As can be seen from FIGS. 1 to 4, the electromagnetic cooking table 2 includes a visualization device 8 for the presence of the home appliance 1 or the cooking container on the electromagnetic cooking table 2. This visualization device 8 is connected to the second optical device 5, detects whether the home appliance 1 or the cooking container is present on the electromagnetic cooking table 2, and informs the user of the information. In fact, if the second optical device 5 does not detect a light beam, the visualization device 8 indicates that the home appliance 1 or cooking container is not present on the electromagnetic cooking table 2.

  FIG. 2 shows the home appliance system in a state where the first optical device 4 is centered with respect to the second optical device 5. In this case, the first optical device 4 directly receives one or more light beams 11 transmitted by the second optical device 5, and the second optical device 5 is transmitted 1 by the first optical device 4. One or more light beams 10 are received directly. Thus, the electromagnetic cooking table 2 is provided with information that the home appliance 1 or the cooking container is placed on the electromagnetic cooking table 2, but the home appliance 1 or the cooking container is also the home appliance 1 or the cooking container. Information that the electromagnetic cooking table 2 is located below is given.

  The one or more light beams (10, 11) transmitted by the first optical device 4 or the second optical device 5 include state data of the home appliance 1 or the cooking container or the electromagnetic cooking table 2, and the home appliance The state of the product 1 or the cooking container or the electromagnetic cooking table 2 can be known.

  The transmitted light beam (10, 11) includes operation data of the home appliance 1 or the cooking container or the electromagnetic cooking table 2.

  This operation data can operate the operation of the home appliance 1 or the cooking container, and further the electromagnetic cooking table 2.

  The state data and operation data can be exchanged bidirectionally between the home appliance 1 or the cooking container and the electromagnetic cooking table 2.

  3 and 4 show that the home appliance 1 or the cooking container or the electromagnetic cooking table 2 is shifted in the centering of the first optical device 4 relative to the second optical device 5 or the second optical device relative to the first optical device 4. 5 shows a modified home appliance system having a centering deviation measuring device of 5. The centering deviation measuring device includes a photosensitive panel 9 that reacts to light rays. The photosensitive panel 9 is disposed on the electromagnetic cooking table 2 or at the bottom of the home appliance 1 or the cooking container, and can mark the position of the light beam incident on the photosensitive panel 9.

  The centering deviation measuring device is connected to the display device 16 of the position of the incident light with respect to the photosensitive panel 9 which can visualize the relative positions of the two optical devices (4, 5) in real time, The optical device 5 is fixed with respect to the electromagnetic cooking table 2, and the first optical device 4 is movable with respect to the electromagnetic cooking table 2.

  The user can correct the alignment between the two optical devices (4, 5) based on this visualized result.

  In general, and as can be seen from FIGS. 1 to 4, the home appliance 1 or cooking container, as well as the electromagnetic cooking table 2, includes a user interface 14. This user interface 14 is adapted to receive operational data on the input side. The user interface 14 includes touch keys or electromechanical keys. The information input through the user interface 14 directly operates the function of the home appliance system element itself provided with the user interface 14, or the home appliance system is reconfigured by the first optical device 4 or the second optical device 5. Can be transmitted to one element.

  When using the home appliance 1 or the cooking container together with the electromagnetic cooking table 2, it is conceivable to encounter several cases. First, there may be no home appliances 1 or cooking containers placed on the electromagnetic cooking table 2. In this case, the optical sensor of the second optical device 5 does not detect the light beam. The microcontroller 13 interprets the information and the result is visualized on the visualization device 8.

  When the home appliance 1 or the cooking container is placed on the electromagnetic cooking table 2, the two optical devices (4, 5) may or may not be aligned.

  When the alignment of the two optical devices (4, 5) is not completed, the second optical device 5 of the electromagnetic cooking table 2 reflects the light transmitted by itself to the home appliance 1 or the bottom of the cooking container. You will receive light rays that originate mainly from. The second optical device 5 identifies the intensity of the received light beam, and on the basis of the received light beam intensity, when the received light beam intensity is less than a certain threshold, the first optical device 4 of the household appliance 1 or the cooking container. Is adapted to conclude that it is offset with respect to the second optical device 5 of the electromagnetic cooking table 2.

  The visualization of the offset is performed via the display device 16 described above, via the display 7, or simultaneously via both.

  When the two optical devices (4, 5) are facing each other, the second optical device 5 receives the one or more light beams 10 transmitted by the first optical device 4 directly. Thereby, the second optical device 5 reaches the strength threshold required to detect the correct alignment of the first optical device 4. Then, the display 7 indicates that the alignment of the two optical devices (4, 5) has been made by a change in the state of the diode, while the display device 16 has a bright spot superimposed on the center of the crosshair line of sight. This indicates that correct alignment has been achieved.

  When the alignment is possible, bidirectional data exchange can be performed, and the operation of the electromagnetic cooking table 2 can be performed either through the home appliance 1 or the cooking container, or directly through the electromagnetic cooking table 2. In this case, it is possible to perform the operation via the user interface 14 capable of inputting operation data.

  For example, in this case, the user can operate the heating intensity of the electromagnetic cooking table 2 through the home appliance 1 or the cooking container.

  Various modifications and / or improvements apparent to those skilled in the art may be made to the embodiments of the invention described herein without departing from the framework of the invention as defined by the appended claims. You will understand that you can.
