Wire coil for electromagnetism electric rice cooker and coiling method thereof

Abstract

The invention discloses a wire coil for an electromagnetism electric rice cooker and a coiling method thereof. The wire coil comprises a coil disk support, a magnetic strip and an enamel-cover stranded wire. Coiling grooves are formed on the curved surface of the concave surface of the coil disk support. The enamel-cover stranded wire is sequentially coiled into the coiling grooves. The magnetic strip is arranged on the convex surface of the coil disk support. An inner hole for insertion of one end of the enamel-cover stranded wire is formed in the center of the inner side of the coil disk support. At utilization time, one end of the enamel-cover stranded wire passes through the inner hole of the coil disk support, and then is coiled from inside to outside in the anticlockwise direction along the coiling grooves, when coiled through a wire jumper slot, the enamel-cover stranded wire is coiled outward for one circle, and after wire coiling is finished, a boss is heated and compressed so as to block the enamel-cover stranded wire. The wire coil is quick in heat dissipating, dense and even in generated excitation wire, economic and environment-friendly, and realizes three-dimensional heating.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to a wire reel for an electromagnetic rice cooker and a winding method thereof. Background technique [0002] On the one hand, the coil disks of electromagnetic electric cookers on the market are complex in production process, low in efficiency and high in cost. On the other hand, the heating coils of ordinary electric rice cookers and electric pressure cookers use tubular electric heating elements as heating elements. The elements are bent and formed, enter the mold, and cast aluminum into various forms of aluminum heating coils. The heating can only be performed on the pot. The bottom part is heated, the heating is extremely uneven, and the energy efficiency is also very low. Moreover, the electromagnetic electric pressure cooker has not yet appeared in the domestic market. Contents of the invention [0003] The object of the present invention is to provide a heating co...
