Problems solved by technology
[0003] The inventors of the present application have found through research on similar existing solutions for improving the effect of electromagnetic heating that most of the solutions are not comprehensive enough, beautiful or have complex implementation methods, etc.
For example, the current solutions are basically some three-dimensional coupling auxiliary heating devices (only solve the side heating), which leads to the loss of the other. The effect is like adding an induction cooker, which makes the device larger in size and complex in structure, and does not solve the problem that the electromagnetic heating is too concentrated on the inner ring. The problem
Moreover, the vast majority of users who use induction cookers now use pans, so that these devices do not play a big role

Embodiment Construction
[0025] The application will be described in further detail below in conjunction with the accompanying drawings and embodiments. In particular, it is pointed out that the following examples are only used to illustrate the present application, but not to limit the scope of the present application. Likewise, the following embodiments are only some of the embodiments of the present application but not all of them, and all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present application.
[0026] This application first proposes a method for improving the magnetic field distribution of electromagnetic heating and its heating effect, such as Figure 4 As shown, set a coil with a power 1000w-1500w larger than the excitation coil and a diameter 5-10cm larger than the excitation coil. The coil is connected in series with an equivalent resonance capacitor that is about 1 times larger than the resonance...

The invention discloses a method for improving the distribution of an electromagnetic heating magnetic field and the heating effect of the electromagnetic heating magnetic field, and the method changes the distribution of the magnetic field of an electromagnetic supply device in a coil coupling and conversion consumption manner, thereby achieving the improvement of the heating effect of the electromagnetic heating device on an object. Wherein a coupling coil is arranged between an electromagnetic supply device and a heating object, and related data of the coil are changed to improve electromagnetic heating magnetic field distribution and heating effect, so that the coil plays a role in energy conversion and transfer; particularly, the effect of improving the electromagnetic heating magnetic field distribution and the heating effect can be achieved by changing the number of turns, the diameter, the density, the position, the thickness or the resonant capacitance and the like of the coil. The invention further relates to a device for improving the electromagnetic heating magnetic field distribution and the heating effect thereof. According to the method or device, the electromagnetic heating mode can adapt to more heating requirements and scenes, and the use experience of electromagnetic heating is improved.
Description
technical field [0001] The present application relates to the field of electromagnetic heating, in particular to a device for improving the magnetic field distribution of electromagnetic heating and its heating effect. Background technique [0002] Electromagnetic supply devices such as induction cooker and ZVS high-frequency heating have been widely used by people nowadays. Electromagnetic heating technology has been widely used in people's daily life whether it is used for heating food or other objects. However, compared with other heating methods, electromagnetic heating still has various disadvantages. For example, when the induction cooker heats the pot, the eddy current heating generated is always concentrated at the inner ring of the center of the bottom of the pot, while the heating effect of the outer ring is not ideal, causing the bottom of the pot to be heated. Uneven and deformed, or heated ingredients are mushy, burnt, or undercooked, especially when cooking wit...
