That is, by the first coil 31 and the third coil 213, it is possible to realize power supply of the home appliance 200 to the input device 100 and bidirectional communication of the home appliance 200 with the input device 100. The state information of the home appliance 200 may include a current operation mode of the home appliance 200, a temperature (e.g., a heating temperature, a cooling temperature), a remaining time period of operation (e.g., a remaining time period of heating), a selected cooking recipe, and the like.
Referring to fig. 1 to 4, in some embodiments, the household appliance 200 includes a second magnetic element 215 located inside the panel 202, the second magnetic element 215 is disposed corresponding to the placement area 211, the second magnetic element 215 is used for attracting the input device 100, the second magnetic element 215 is annular, and a second shielding element 212, a fourth coil 214 and a third coil 213 are sequentially distributed inside the second magnetic element 215 from outside to inside.
In this way, the second magnetic member 215 ensures that the panel connection portion of the input device 100 and the household appliance 200 is not displaced, and the second shielding member 212 can effectively shield the interference of the second magnetic member 215 to the third coil 213 and the fourth coil 214.
Specifically, the second magnetic member 215 is in an annular structure, and the second shielding member 212, the fourth coil 214 and the third coil 213 are sequentially distributed inside the second magnetic member 215 from outside to inside, that is, the second shielding member 212 separates the second magnetic member 215 from the fourth coil 214 and the third coil 213, so as to effectively shield the interference of the second magnetic member 215 to the fourth coil 214 and the third coil 213, avoid the magnetic field of the second magnetic member 215 from influencing the normal operation of the fourth coil 214 and the third coil 213, and ensure the reliability of the household appliance 200.
Specifically, in some embodiments, the second magnetic member 215 may be a permanent magnet, and the material may be, but is not limited to, an alnico permanent magnetic alloy, an iron-chromium-cobalt permanent magnetic alloy, a permanent magnetic ferrite, a rare earth permanent magnetic material, a composite permanent magnetic material, and the like. In some embodiments, the second magnetic member 215 may include an electromagnet. In addition, the first magnetic member 121 or the iron ring 1215 may be disposed inside the housing 10 of the input device 100, and the input device 100 may be detachably disposed on the panel by the mutual attraction between the first magnetic member 121 and the second magnetic member 215 or the attraction of the second magnetic member 215 to the iron ring 1215.
