Embodiment Construction

[0020] Further illustrate the technical scheme of this patent below in conjunction with accompanying drawing.

[0021] Figure 1 and figure 2 As shown, a kind of electromagnetic heating reel of a kind of induction cooker reversely wound round by turn: it includes a wire reel frame 1 and a coil winding 2, the coil winding 2 is installed on the wire reel frame 1, and the wire reel frame 1 includes several concentrically arranged The annular winding grooves 3 of equal width are separated by annular retaining ribs 13 between adjacent winding grooves 3, and all the annular retaining ribs that separate the winding grooves 3 are separated in a certain radial direction. The ribs 13 are opened with gaps of equal width, so that all the gaps are on the same straight line segment. These gaps are called reversing diameter-reducing grooves 4, and the reversing diameter-reducing grooves 4 make each winding groove 3 communicate with each other; Including wire inlet trough 11 and wire outlet...

Abstract

The invention discloses a cycle-based inverted winding type electromagnetic heating wire coil and an induction cooker. The electromagnetic heating wire coil comprises a rack and a coil winding; the rack comprises a plurality of concentric annular coiling grooves, wire feeding grooves, wire discharging grooves and reversing reducing grooves; the coil winding coils into the coiling grooves, wherein the coil winding is reduced in the reversing reducing grooves and then returns to enter the adjacent winding grooves to be reversely wound after coiling in a plurality of layers in the coiling grooves. The induction cooker adopting the electromagnetic heating wire coil can avoid the problem that the magnetic fluxes generated nearby by a coil between adjacent loops cancel each other out in the traditional one-way winding method; therefore, the utilization rate of the magnetic flux generated by the coil can be increased, and uniform heating can be achieved.

Description

technical field [0001] The technical solution relates to the field of small household electrical appliances, in particular to an electromagnetic heating reel and an induction cooker which are reversely wound round by round. Background technique [0002] The electromagnetic coil is the core component of the induction cooker, and the high-efficiency and high-performance electromagnetic coil has become the key to the development of the induction cooker technology. The magnetic flux generated by each turn of the unidirectional coil is partially offset, resulting in low flux utilization and uneven heating. The typical phenomenon is that when using an induction cooker to cook food with little water, such as fried vegetables, the induction cooker The local temperature in the small area of ​​the center is too high, and the surrounding temperature is low, so that the vegetables are easily partially burnt to black and burnt, and the cooking effect is obviously not as good as that of t...
