Description

Technical Field

[0001] The invention relates to the technical field of gas cookers, in particular to a coil disk of an induction cooker. Background Art

[0002] The existing induction cooker coil disk is set to be circular, and the coil is wound in a ring shape on the coil disk, but the existing coil has a heating blind spot. The authorization announcement number is CN203378076U, and the invention name is a prior art 1 of a multi-coil uniformly heated electromagnetic wire disk. It discloses a multi-coil uniformly heated electromagnetic wire disk, which is composed of a wire disk base and a number of small coils evenly distributed on the wire disk base. The small coils are composed of a magnetic core, a winding skeleton and a coil. The coils are arranged on the winding skeleton, and the coils are wound with an enameled wire or each coil is wound separately and then the enameled wire between the coils is connected by spot welding. However, the prior art 1 still has a heating blind spot, and the small coils are prone to overheating, and the winding of the small coils is prone to make the induction cooker thicker. The authorization announcement number is CN206251377U, and the invention name is Prior Art 2 of Coil Disk and Electromagnetic Cooking Utensils. It discloses a coil disk and an electromagnetic cooking utensil, wherein the coil disk includes a coil disk seat and a winding coil installed on the coil disk seat, the winding coil includes a first winding located in the middle of the coil disk seat, and a plurality of second windings arranged around the first winding, and the plurality of second windings are arranged at intervals in the circumferential direction of the first winding; wherein the inner ring diameter of the first winding is less than or equal to 12 mm. The technical solution of the present invention improves the first winding in the middle of the coil disc seat so that its inner ring diameter is less than 12 mm, thereby greatly reducing the area of ​​the blind spot in the middle of the coil disc and improving the uniformity of heating of the electromagnetic cooking appliance. However, the prior art 2 still has a heating blind spot. The prior art 2 does not set a winding groove for each coil. It can be seen from the attached figure of the prior art 2 that the prior art 2 fixes the position of the second winding coil by setting a block, which will result in a large area without a coil in the center of the second winding coil, and the second winding coil is set at intervals, which also leads to gaps between the coils, so there is a heating blind spot. The electromagnetic cooker with a heating blind spot is prone to uneven heating when heating fried food, resulting in some parts of the fried food being burnt, but some parts are still undercooked. Therefore, a electromagnetic cooker coil disc without a heating blind spot and capable of uniform heating is needed. Summary of the invention
