Problems solved by technology

In order to obtain greater power, it is often necessary to increase the length and area of ​​the coil winding, which is not conducive to the miniaturization of the induction cooker
[0004] In addition, the traditional coil winding is usually pasted in the winding groove on the surface of the winding bracket by glue, and the high temperature generated during work will cause the glue used for pasting to produce harmful smell, which is not conducive to human health
And because the glue is attached to the outer layer of the entire coil winding, it will seriously affect the heat dissipation of the coil winding

[0058] The double-layer induction cooktop coil disk provided by the first embodiment of the present invention, such as Figure 1 to Figure 2 As shown, it is generally composed of a coil disk support 4, a coil 5, a magnetic strip 6 and so on. The coil disk support has a first surface ( figure 1 In the upper surface) and the second surface ( figure 2 The upper surface of the middle, that is, the surface where the magnetic strip 6 is located), the coil 5 is wound on the first surface and the second surface of the coil disk support 4. Since the coil 5 is wound on the two surfaces of the coil disk support 4, compared with the existing single-layer coil structure, the length of the coil 5 in the same area is doubled. Correspondingly, the thermal efficiency of the coil disk and the induction cooker using the coil disk Will increase substantially. In addition, since the coils 5 on the upper and lower surfaces are separated by the coil disk support 4, the thermal interference between t...

[0069] The coil disk provided by the second embodiment of the present invention, such as Figure 7 to Figure 12 Shown. The coil disk of the second embodiment is basically the same in structure as the first embodiment. The main difference is that the second embodiment uses alternating slots 70 or 75 instead of the coil vias 46 in the first embodiment as a channel between the first surface and the second surface. . For the convenience of description, the same or substantially the same structure will use the names and reference signs in the first embodiment here, and will not be described in detail in the specification.

[0070] The alternating slots 70 or 75 penetrate the first surface and the second surface of the coil disk support 4 to communicate the coil slots (including the outer coil slot 410, the inner coil slot 411, and the second coil slot 42) on the first and second surfaces. Facilitate the winding of subsequent coils. In this embodiment, since only the inner coil slot ...

Abstract

The invention provides a coil panel which comprises a coil panel support (4) and a coil (5), wherein the coil panel support (4) is provided with a first surface and a second surface which are arranged in a back-to-back mode, and the coil (5) is wound around the first surface and the second surface of the coil panel support (4). The invention further provides an assembling method of the coil panel, the coil panel support and an electromagnetic range. Due to the fact that the coil is wound around the two surfaces of the coil panel support, the length of the coil is doubled in the same area, and correspondingly, the thermal efficiency of the coil panel and the thermal efficiency of the electromagnetic range provided with the coil panel can be improved substantially. Besides, due to the fact that the coil portion on the upper surface and the coil portion on the lower surface are separated by the coil panel support, not only can thermal interference between the coil portion on the upper surface and the coil portion on the lower surface be avoided, but also electric interference between the coil portion on the upper surface and the coil portion on the lower surface can be avoided.

Description

Technical field [0001] The invention relates to the field of electromagnetic cookers, and in particular to an electromagnetic coil disk and a coil disk support for electromagnetic cookers. Background technique [0002] The coil plate is a key component of the induction cooker, which largely determines the thermal efficiency of the induction cooker. At present, the common coil disk includes a winding support, a magnetic strip and a coil winding. A winding slot is provided on the upper surface of the winding support, and the coil winding is wound in the winding slot on the upper surface of the winding support, and the magnetic strip is radial. Distributed on the lower surface of the winding support. During specific installation, the magnetic strip can be pasted on the lower surface of the winding support, or a card slot can be provided on the lower surface of the winding support, and the magnetic strip can be clamped in the card slot. For more technical details, please refer to t...
