Abstract

The utility model relates to a coil structure capable of eliminating a heating dead zone in the center of an electromagnetic heating coil. The coil structure comprises a spiral coil. A spring-shaped coil is arranged in the center of the spiral coil. The coil structure has the advantages that the structure is simple and reasonable, the cookware is ensured to be heated evenly and the cooking quality is improved, and can be widely used for induction cookers.

Description

A kind ofly eliminate the loop construction that electromagnetism adds thermal center (-tre) heating blind area

Technical field

The utility model relates to a kind of electromagnetic coil structure, particularly a kind ofly eliminates the loop construction that electromagnetism adds thermal center (-tre) heating blind area.

Background technology

At present, its operation principle of common on the market electromagnetic oven is by switching on to spiral coil to produce alternating magnetic field, when when containing irony pan bottom and place boiler face, pan promptly cuts the alternation magnetic line of force and partly produces the electric current (being eddy current) of alternation in the pan bottom metal, eddy current makes the random motion of pan iron molecule high speed, and molecule runs foul of each other, rubs and produces heat energy, makes irony pan heating at a high speed voluntarily itself, be used for heating and cooking food, thereby reach the purpose of cooking; The centre of common this loop construction is hollow, causes pan centre caloric value little, and when culinary art, food mainly is to concentrate on the pan middle part, causes user's effect when culinary art bad, at above-mentioned shortcoming, is necessary to make improvement.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provide a kind of simple and reasonable for structure, can make the pan heating evenly add the loop construction of heating blind area, thermal center (-tre) with the elimination electromagnetism that improves cooking quality.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind ofly eliminate the loop construction that electromagnetism adds thermal center (-tre) heating blind area, comprise spiral coil, below, described spiral coil middle part is provided with the coil of spring-like.

In the utility model, be provided with bar magnet in the coil of described spring-like for its solderless wrapped connection, the coil that is positioned at spring-like is wrapped with insulator.

The beneficial effects of the utility model are: by the coil of spring-like is set below the spiral coil middle part, utilize the spring-like coil to produce the stronger alternation magnetic line of force, improve the caloric value at pan center greatly, eliminated the heating blind area at pan middle part, effectively raised cooking quality.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a structural representation of the present utility model.

Embodiment

With reference to Fig. 1, Fig. 2, a kind ofly eliminate the loop construction that electromagnetism adds thermal center (-tre) heating blind area, comprise spiral coil 1, below, described spiral coil 1 middle part is provided with the coil 2 of spring-like.

In the utility model, be provided with bar magnet 3 in the coil 2 of described spring-like for its solderless wrapped connection, the coil 2 that is positioned at spring-like is wrapped with insulator.

The utility model is by being provided with the coil 2 of spring-like below spiral coil 1 middle part, utilize spring-like coil 2 to produce the stronger alternation magnetic line of force, improve the caloric value at pan center greatly, eliminated the heating blind area at pan middle part, effectively raised cooking quality.

The utility model is simple and reasonable for structure, can make the pan heating evenly to improve cooking quality, is the loop construction that a kind of elimination electromagnetism that is widely used on the electromagnetic oven adds heating blind area, thermal center (-tre).

Claims

1. eliminate the loop construction that electromagnetism adds heating blind area, thermal center (-tre) for one kind, comprise spiral coil (1), it is characterized in that: below, described spiral coil (1) middle part is provided with the coil (2) of spring-like.

2. a kind of loop construction that electromagnetism adds thermal center (-tre) heating blind area of eliminating according to claim 1 is characterized in that being provided with in the coil (2) of described spring-like the bar magnet (3) for its solderless wrapped connection, and the coil (2) that is positioned at spring-like is wrapped with insulator.
