As shown in fig. 1 and 2, the upper side of the middle coil support 2 may be provided with a panel 10, the panel 10 being capable of contacting the bottom of the pot. With the above arrangement, as shown in fig. 3, when the electromagnetic heating apparatus of the present invention uses the pan 99, the middle coil 1 is correspondingly close to the pan 99, the peripheral coil 3 is located below the pan 99, the middle coil 1 works to heat the middle part of the pan 99, and the peripheral coil 3 does not work; as shown in fig. 4, when the electromagnetic heating device of the present invention uses the arc bottom pan 98 (the arc bottom pan 98 belongs to a concave bottom pan), the middle coil support 2 moves downward relative to the peripheral coil support 4, so that the peripheral coil 3 can approach the arc bottom pan 98, and the peripheral coil 3 and the middle coil 1 can work simultaneously or alternately; compared with the prior art, the electromagnetic heating device of the invention avoids that only the bottom center of the arc bottom pan 98 is effectively heated when the arc bottom pan 98 is used, or that only the peripheral part of the pan 99 is effectively heated when the pan 99 is used (in other words, the middle part of the pan 99 is not effectively heated), so that the electromagnetic heating device of the invention can adapt to the use of the pan 99 and the arc bottom pan 98, and has good compatibility to heated appliances.
In some embodiments, as shown in fig. 3 and fig. 4, the electromagnetic heating device of the present invention further includes a base 8, the peripheral coil support 4 is fixedly connected with the base 8, specifically, the base 8 is formed with a first support column 801, an outer edge portion of the peripheral coil support 4 is fixedly connected with an upper end of the corresponding first support column 801 through a corresponding screw, as shown in fig. 1, the peripheral coil support 4 may be formed with a guide arm 401, the middle coil support 2 may be formed with a sliding column 201, the sliding columns 201 are uniformly distributed circumferentially, and the sliding column 201 is adapted to movably pass through the corresponding guide arm 401, thereby realizing the relative sliding connection between the middle coil support 2 and the peripheral coil support 4; the electromagnetic heating device of the present invention further comprises an electric lifting mechanism 7, the electric lifting mechanism 7 is in driving connection with the middle coil support 2, and the electric lifting mechanism 7 capable of driving the middle coil support 2 to move up and down is in the prior art, for example, as shown in fig. 1, the electric lifting mechanism 7 comprises a screw rod, a nut and a motor, the screw rod is fixedly connected with the middle coil support 2 relatively through a bracket 701, the screw rod is in threaded connection with the nut, the nut can be in rotational connection with the base 8, the motor can drive the nut to rotate through a gear pair, and then the motor can drive the middle coil support 2 to move up and down. For example, the electric lifting mechanism 7 may include a connecting rod and a cam, where the cam is driven to rotate by a corresponding motor, the connecting rod is in contact with and connected to the cam, and the connecting rod is fixedly connected to the middle coil support 2, so that the cam can drive the middle coil support 2 to lift. By arranging the electric lifting mechanism 7, the relative lifting of the middle coil support 2 and the peripheral coil support 4 is realized in an electric mode, so that the electromagnetic heating device is simple and convenient to operate, and a control system for controlling the electric lifting mechanism 7 in the prior art can be arranged, so that the middle coil support 2 can be lifted automatically. Similarly, the middle coil support 2 can be fixed, and the electric lifting mechanism 7 is in driving connection with the peripheral coil support 4, so that the middle coil support 2 and the peripheral coil support 4 can be lifted electrically and relatively.
In some embodiments, as shown in fig. 5 and 6, the peripheral coil support 4 is fixedly connected to the base 8; the electromagnetic heating device of the invention also comprises a first spring 71 for driving the middle coil support 2 to reset upwards, one end of the first spring 71 is connected with the peripheral coil support 4, the other end corresponding to the first spring 71 is connected with the middle coil support 2, specifically, the first spring 71 can be sleeved outside the corresponding sliding column 201, and the lower end of the first spring 71 is in contact connection with the corresponding guide arm 401; as shown in fig. 5, when the pan 99 is put on the electromagnetic heating device of the present embodiment to be used, the pan 99 may be supported and restrained by the upper end of the peripheral coil support 4 or the pan 99 may be supported and restrained by the stopper 11, the middle coil 1 may be close to the bottom of the pan 99, and after the pan 99 is put on the electromagnetic heating device of the present embodiment, the first spring 71 may be further compressed by the gravity of the pan 99 or the middle coil 1 may be kept stationary; when the arc bottom boiler 98 is put on the electromagnetic heating apparatus of the present embodiment to be used as shown in fig. 6, the gravity of the arc bottom boiler 98 compresses the first spring 71, and thus the middle coil 1 descends with respect to the peripheral coil 3 until the upper end of the peripheral coil holder 4 or the stopper 11 contacts the arc bottom boiler 98, and both the middle coil 1 and the peripheral coil 3 can heat the arc bottom boiler 98 effectively in the state shown in fig. 6. Since the middle coil 1 descends by the gravity of the pot, when the pot is moved away from the electromagnetic heating device of the invention, the middle coil 1 is pushed to ascend and reset by the elastic restoring force of the first spring 71, and the relative lifting of the middle coil support 2 and the peripheral coil support 4 is realized by arranging the first spring 71, so that the structure is simple and the cost is low.
In some embodiments, as shown in fig. 7 and 8, the middle coil support 2 is fixedly connected with the base 8, specifically, the base 8 is formed with a second support column 803, the middle coil support 2 is fixedly connected with the upper end of the second support column 803, the electromagnetic heating device of the invention further comprises a second spring 72 for driving the peripheral coil support 4 to reset upwards, one end of the second spring 72 is connected with the peripheral coil support 4, the other end corresponding to the second spring 72 is connected with the base 8, specifically, the base 8 is formed with a guide post 802, the second spring 72 is sleeved outside the corresponding guide post 802, and the upper end of the second spring 72 is in contact with the peripheral coil support 4. As shown in fig. 7, when the pan 99 is put on the electromagnetic heating apparatus of the present embodiment to be used, the weight of the pan 99 lowers the peripheral coil support 4, and the second spring 72 is elastically compressed until the middle coil 1 approaches the pan 99 (the pan 99 is supported by the middle coil support 2 or the pan 99 is supported by the panel 10), in the state of fig. 7, the peripheral coil 3 is not operated, and the middle coil 1 heats the pan 99; as shown in fig. 8, when the arc bottom boiler 98 is used on the electromagnetic heating device of the present embodiment, the middle coil 1 and the peripheral coil 3 can simultaneously and effectively heat the arc bottom boiler 98. By providing the second springs 72, a relative elevation of the central coil support 2 and the peripheral coil support 4 is achieved in a simple and low-cost manner.
In some embodiments, as shown in fig. 4, the middle coil 1 is set to a flat coil (i.e., a flat coil), the peripheral coil 3 is set to an arc-shaped coil, that is, the three-dimensional shape of the peripheral coil 3 can be adapted to the arc-shaped outer wall of the arc-bottom pan 98, and as can be seen from fig. 3, when the pan 99 is used, since the middle coil 1 is set to a flat coil, the bottom of the pan 99 can be well matched with the middle coil 1, so that the pan 99 is effectively heated; as can be seen from fig. 4, when the arc bottom boiler 98 is used, since the three-dimensional shape of the peripheral coil 3 is adapted to the outer wall shape of the arc bottom boiler 98, even if there is a shortage in matching the middle portion of the arc bottom boiler 98 with the middle portion coil 1, the arc bottom boiler 98 can be efficiently heated by the peripheral coil 3.
In some embodiments, as shown in fig. 9, the middle coil 1 and the peripheral coil 3 are both arc-shaped coils, so that the electromagnetic heating device of the present embodiment is preferably matched with the arc bottom pan 98, and the middle coil 1 can effectively heat the pan 99 when the bending amplitude of the middle coil 1 is smaller.
In some embodiments, as shown in fig. 10, the middle coil 1 is a flat coil, the peripheral coil 3 is a cylindrical coil, and the cup 97 has a cylindrical outer wall and a flat bottom, so that the cylindrical peripheral coil 3 can be adapted to the cylindrical outer wall of the cup 97, and the middle coil 1 can be well adapted to the flat bottom of the cup 97.
In some embodiments, as shown in fig. 11, the electromagnetic heating device of the present invention further includes a sealing ring 12, as shown in fig. 12, where the sealing ring 12 includes a first flange 1201, a second flange 1202, and an elastic extension 1203, and the elastic extension 1203 is disposed between the first flange 1201 and the second flange 1202, as shown in fig. 11, where the first flange 1201 is connected with the middle coil support 2 in a sealing manner, and the second flange 1202 is connected with the peripheral coil support 4 in a sealing manner, and the first flange 1201 is disposed on an upper side of the second flange 1202. Specifically, the lower side of the first flange 1201 is provided with a first pressing ring 13, the first flange 1201 is arranged between the middle coil support 2 and the first pressing ring 13, the first pressing ring 13 is relatively and fixedly connected with the middle coil support 2 through corresponding screws, the second flange 1202 is arranged between the second pressing ring 14 and the peripheral coil support 4, and the peripheral coil support 4 is relatively and fixedly connected with the second pressing ring 14 through corresponding screws. When the peripheral coil bobbin 4 and the middle coil bobbin 2 are relatively moved in the up-down direction, the elastic extension 1203 shown in fig. 12 is elastically deformed to open or close, that is, the gap between the peripheral coil bobbin 4 and the middle coil bobbin 2 is closed by the seal ring 12, preventing water from leaking into the space below the middle coil bobbin 2.
In some embodiments, as shown in fig. 1 to 9, the electromagnetic heating device of the present invention further includes a limiter 11 for surrounding and contacting the outer wall of the pan, where the arc bottom pan 98 and the pan 99 belong to the pan, and the "surrounding contact" refers to that the mutual contact points of the limiter 11 and the outer wall of the pan are circumferentially distributed (as shown in fig. 5, the limiter 11 is preferably in contact with the lower end corner of the pan 99), for example, the limiter 11 may be configured to be capable of contacting the outer wall of the pan everywhere, so that when the pan is placed on the electromagnetic heating device of the present embodiment, the pan is subjected to the positioning action of the limiter 11 in a horizontal plane, thereby avoiding the pan from shifting during cooking, which is beneficial for safety; the stopper 11 may also form an upward supporting force on the pot, for example, in the embodiment shown in fig. 6, when the arc bottom pot 98 is placed on the panel 10, the gravity of the arc bottom pot 98 compresses the first spring 71, the arc bottom pot 98 descends, and when the outer wall of the arc bottom pot 98 contacts the stopper 11, the stopper 11 plays a role in limiting the arc bottom pot 98, and at this time, the elastic restoring force of the first spring 71 may keep the panel 10 in contact with the middle of the arc bottom pot 98.
Further, as shown in fig. 2, the limiter 11 may be configured to be annular, that is, in this embodiment, the limiter 11 may contact the outer wall of the pot entirely, so as to more fully achieve the effect of "surrounding and contacting" the pot, and thus the limiting effect of the limiter 11 on the pot is more stable. As shown in fig. 15, a rounded corner 1101 is formed at the inner upper end of the retainer 11, when a person places the pot on the retainer 11, the pot may not be aligned, and when the pot is moved by hand to align the position, the rounded corner 1101 can reduce the friction resistance of the pot, so as to facilitate the alignment of the pot.
In some embodiments, as shown in fig. 5, the inner bottom of the base 8 is formed with a water receiving groove 81 for receiving water flowing down from the gap between the middle coil support 2 and the peripheral coil support 4, and the bottom of the water receiving groove 81 is formed with a water leakage hole 8101, so that when water flows between the middle coil support 2 and the peripheral coil support 4 due to carelessness during cooking, the water can flow down into the water receiving groove 81, and then the water is discharged from the water leakage hole 8101 to the outside of the base 8, thereby avoiding the influence of the water on circuit devices arranged in the base 8. Specifically, the water receiving groove 81 is an annular water groove, and the water receiving groove 81 is provided below the correspondence of the gap between the center coil holder 2 and the outer coil holder 4.
The middle coil 1 and the peripheral coil 3 can be wound by the same wire, fig. 13 schematically shows the positions of the coil connecting line segments 101, in other words, the middle coil 1 and the peripheral coil 3 are connected together by the coil connecting line segments 101, in which case the middle coil 1 and the peripheral coil 3 are simultaneously energized, for example, in the application shown in fig. 3, the middle coil 1 heats the pan 99, and the peripheral coil 3 only mainly acts as a wire, in the application shown in fig. 4, the middle coil 1 and the peripheral coil 3 simultaneously heat the arc bottom pan 98; or the middle coil 1 and the peripheral coil 3 can be wound by corresponding leads independently (as shown in fig. 14), so that the middle coil 1 works and the peripheral coil 3 does not work (power off) under the application condition shown in fig. 3; in the application case shown in fig. 4, the central coil 1 and the peripheral coil 3 may be operated simultaneously, but of course, the central coil 1 and the peripheral coil 3 may also be operated alternately. High temperature resistant materials such as a micro-crystal plate, a ceramic plate, a silica gel piece, an aluminum piece, a mica piece and the like can be respectively arranged between the middle coil 1 and the pot as well as between the peripheral coil 3 and the pot to serve as supporting or isolating functions.
