Problems solved by technology

Therefore, this electroplated LDS coil disk has the following disadvantages: 1) Due to the inconsistent ductility of Cu and plastic at high temperature, the coil is easy to fall off from the plastic surface after heating; 2) Due to the size and shape errors of plastic parts, the LDS molding , the spacing error of the coils is large, and when the plating thickness increases, overflow plating is prone to occur between one coil and another coil, resulting in a short circuit between multiple coils

Abstract

The invention discloses an LDS coil disk and an electromagnetic cooking appliance having the same. The LDS coil disk comprises: a coil disk holder, wherein the outer surface of the coil disk holder isprovided with at least one circular wire groove; and at least one coil embedded in the wire groove. According to the LDS coil disk of the embodiment of the invention, the coil and the coil disk holder are mutually restrained, the coil is not easy to fall off the coil disk holder, and the multi-turn coils are indirectly consistent, thereby effectively suppressing the overflow plating. The LDS coildisk has high stability and high reliability.

Description

technical field [0001] The invention relates to the field of electric appliance manufacturing, in particular to an LDS coil disk and an electromagnetic cooking appliance with the LDS coil disk. Background technique [0002] In the related art, there are two types of coil disks for electric rice cookers, one adopts the winding method, has a complex structure and many parts, and the other adopts LDS (laser direct structuring) electroplated LDS coil disks. This electroplated LDS The coil plate activates the plastic surface, and then electroplates the coil on the surface of the coil plate support by electroless plating and electroplating. The coil coating is directly formed on the magnetic plastic surface by laser. Therefore, this electroplated LDS coil disk has the following disadvantages: 1) Due to the inconsistent ductility of Cu and plastic at high temperature, the coil is easy to fall off from the plastic surface after heating; 2) Due to the size and shape errors of plastic...
