Method for winding heater wire disk of electromagnetic heater

Abstract

The present invention involves a winding method of the heating lines in the induction cooker , especially could be applied to the heating roil rod that could be used in planar pot and globoid pot to reduce the fume when cooking. Its characteristics are as follows: the heating roil rod is made by winding the heating lines densely and loosely; there exists some gap between heating lines; the distance between heating lines in the heating roil rod could be equidistant or arbitrary; the shape of the heated roil rod could be planar roil rod or globoid roil rod; The distance between different heating lines would be 0.5mm to 5 mm; This invention could control the uniformity of the magnetic field strength through density combination of heating line, so the magnetic field strength in the whole coil rod to could be more uniform in different diameter location, and additionally pot utensils would be heated obviously more uniform. It could overcome the phenomenon of mass of fume when cooking using electric stove, so it is the ideal structure of heating roil rod in the electric stove.

Description

Technical field: [0001] The invention relates to a winding method for a heating coil of an electromagnetic oven, in particular to a heating coil for an electromagnetic oven which is applicable to pans and arc-shaped pans and can reduce oily smoke during cooking in an electromagnetic oven. Background technique: [0002] The induction cooker mainly uses electromagnetic induction to make the current enter the coil made of copper wire wound with iron sheet. Generate magnetic induction, and then generate eddy current through the pot placed on the stove surface to generate heat. Because it cooks food with the heat produced by the pot. Therefore, the stove surface will not be hot, and it will be clean when cooking food, and it is widely used. The existing winding method of the heating reel of the induction cooker is to form a cake-shaped reel by winding multiple strands of enameled wire tightly on the winding surface of the reel support from the inside to the outside, or winding ...

Problems solved by technology

Due to this structure, the magnetic field strength generated by the entire wire reel gradually weakens from the center to the outside when it is working, so that the heat of the heated pot is concentrated in the center, and there is not much heat in most of the outer parts of the pot, so that the pot Uneven heating causes hot oil to splash in the center of cooking, and the kitchen is full of oily smoke. Therefore, most families with induction cookers are only used for cooking food, and very few are used for cooking, which limits the scope of application of the induction cooker.
