As shown in fig. 1 to 4, the electromagnetic coil panel with high energy efficiency according to the first aspect of the present utility model includes a magnetic core support 100 and a coil assembly 200, wherein the magnetic core support 100 adopts a large-area design, so that an insulating framework in the prior art is omitted, and the arrangement of the magnetic core support 100 has a better shielding effect on magnetic lines of force generated by the coil assembly 200, so that the magnetic lines of force can be concentrated more, and the purpose of high energy efficiency is achieved.
Specifically, in order to enhance the use effect of the magnetic core holder 100, the magnetic core holder 100 is preferably a magnetic member having high-frequency low-resistance properties, such as manganese zinc ferrite. The middle part of the magnetic core support 100 is provided with a through hole 110, the shape of the magnetic core support 100 can be a ring shape, and the inner edge and the outer edge of the magnetic core support 100 are respectively provided with a center boss 120 and an edge boss 130. Since the heights of the central boss 120 and the edge boss 130 are higher than the other positions of the magnetic core holder 100, a closed-loop accommodating groove 140 is defined between the central boss 120 and the edge boss 130, and the notch of the accommodating groove 140 faces upward.
The slot is used for accommodating the coil assembly 200, the coil assembly 200 is disposed in the accommodating groove 140, when the coil assembly 200 is conductive, it can generate magnetic force lines outwards, and since the magnetic force lines can be shielded by the magnetic material, the magnetic force lines facing downwards and the magnetic force lines facing sideways are shielded by the magnetic core support 100, so that the magnetic force lines can only diffuse outwards from the slot opening upwards, so that the magnetic force lines can be concentrated in the planar area of the coil panel, thereby concentrating the energy of the magnetic force lines and reducing the energy loss of the magnetic force lines.
Further, since the present utility model omits the provision of an insulating skeleton, in order to avoid a short circuit between the coil assembly 200 and the magnetic core holder 100, an insulating layer 300 may be provided between the coil assembly 200 and the magnetic core holder 100, and the insulating layer 300 may be made of a mica material having a temperature-resistant insulating property, so as to function as a physical insulation between the coil assembly 200 and the magnetic core holder 100.
It will be appreciated that the core holder 100 may be integrally formed by firing, or may be assembled from a plurality of split splices 101. For the manganese-zinc-ferrite, the magnetic core support 100 has a complex structure, so that the difficulty of integrally firing and forming the manganese-zinc-ferrite is high, and in this embodiment, the forming of the magnetic core support 100 is preferably realized by adopting a splicing mode, so as to reduce the production cost and the forming difficulty. Since the magnetic core support 100 has a ring structure with a U-shaped opening, each split joint 101 is preferably a fan structure with a U-shaped opening, and the number of the split joints is four.
When assembling, all the split spliced pieces 101 are respectively bonded with each other by glue, after forming, the magnetic core support 100 can be bonded with a protection plate 400 on the bottom surface of the magnetic core support 100 besides enhancing the mechanical strength by bonding with the insulating layer 300, the protection plate 400 is optionally made of mica material with temperature-resistant insulating property, and at this time, the protection plate 400 is bonded on the bottom surfaces of all the split spliced pieces 101. In other embodiments, all the split joints 101 are assembled by bonding with the insulating layer 300 and the protection plate 400, respectively, so as to omit glue for bonding between two adjacent split joints 101.
In addition, the coil assembly 200 may be formed by one wire 210 or a plurality of wires 210, and the wires 210 are wound in series to form a plurality of turns arranged in layers up and down, and any two adjacent turns have opposite winding directions, i.e. if any one layer of turns is wound in a plane anticlockwise direction, the adjacent layer of turns is wound in a plane clockwise direction, so that the winding method has higher winding efficiency and lower processing cost. When the coil turns are only upper and lower layers, the winding mode can ensure that the inlet and outlet wires of the coil assembly 200 are arranged on the outer side of the coil disc, so that the wiring is convenient.
It can be appreciated that, in the present embodiment, the accommodating groove 140 is an annular groove, so the coil assembly 200 is also annular, and the circular shape has high space utilization and smoother streamline, so the annular design can further reduce cost and energy loss of magnetic force lines. However, the shapes of the accommodating groove 140 and the coil assembly 200 are not limited, and in other embodiments, the accommodating groove and the coil assembly may be rectangular, triangular, etc., but are not limited to the above embodiments.
As shown in fig. 5, in order to reduce the cost, the wires 210 are twisted by a plurality of wires 211, and each of the wires 211 is an enamel wire to avoid a short circuit between the wires 211. In addition, in order to prevent the phenomenon of inter-turn short circuit after the coil turns are tightly wound, the wire 210 is wrapped with a protective sleeve 212 around the periphery of all the wires 211, and the protective sleeve 212 mainly plays a role in insulation protection, and is selected from a polyester film or a teflon film with good temperature resistance and insulation.
As shown in fig. 4, in some embodiments of the present utility model, an insulating layer 500 is adhered to the upper surface of the coil assembly 200, the insulating layer 500 may be made of a mica material or a heat insulation cotton material having a temperature-resistant insulating property, the insulating layer 500 covers the notch of the receiving groove 140, and the insulating layer 500 protects and insulates the coil assembly 200, so that the internal resistance heat generated by the coil assembly 200 is not rapidly dissipated, to maintain the performance of the coil assembly 200. Similarly, the insulating layer 300 and the shielding plate 400 can also provide protection and thermal insulation to the core holder 100 to reduce electromagnetic energy loss.
An electromagnetic heating appliance according to an embodiment of a second aspect of the present utility model includes the energy efficient electromagnetic coil panel according to the embodiment of the first aspect of the present utility model described above, and further includes a housing (not shown in the drawings) in which the energy efficient electromagnetic coil panel is mounted, the magnetic flux output area of the energy efficient electromagnetic coil panel being aligned with the bearing surface of the housing. When a user places the cooker on the bearing surface of the shell and starts the heating switch of the electromagnetic heating device, the energy-efficient electromagnetic coil panel is electrified and generates magnetic lines outwards, and the electromagnetic heating device can electrically heat the cooker according to the first-level energy efficiency standard because the energy-efficient electromagnetic coil panel can concentrate the magnetic lines of force on the bearing surface of the shell to provide relatively large electromagnetic induction energy.
Because the electromagnetic heating device adopts all the technical schemes of all the embodiments, the electromagnetic heating device has at least all the beneficial effects brought by the technical schemes of the embodiments, and the description is omitted herein.
The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
