An induction cooker without a cooling device

Abstract

The invention discloses an electromagnetic oven without a heat radiator. The electromagnetic oven comprises a connecting wire, a host machine mechanism and a cooking range mechanism which are sequentially connected, wherein the connecting wire is connected with an external power supply; the cooking range mechanism comprises a cooking range body shell and a coil panel; the coil panel is arranged in the cooking range body shell; the coil panel is a strip conductor coiled into an S-shaped panel; a clearance is reserved between the adjacent side surfaces of the strip conductor; two end parts of the strip conductor serve as connecting ends which are electrically connected with the output end of a main controller. The structure of the coil panel in the cooking range mechanism is optimized and improved, so that the coil panel is small in calorific value and rapid in heat dissipation during use; the cooking range mechanism is capable of meeting the normal operation requirements of the electromagnetic oven without the heat radiator, and the problem of safety accidents of a coil panel manufactured by tightly coiling up multi-strand wires in the prior art can be well solved; meanwhile, the host machine mechanism and the cooking range mechanism of the electromagnetic oven are separately arranged, so that the heat dissipation effect of the electromagnetic oven is greatly enhanced.

Description

technical field [0001] The invention relates to an electromagnetic cooker, in particular to an electromagnetic cooker without a cooling device. Background technique [0002] As a kind of high-efficiency and energy-saving kitchen utensils, induction cooker is also called induction cooker. The principle of induction cooker is magnetic field induction eddy current heating, that is, using current to pass through the coil to generate a magnetic field. Numerous small eddy currents cause the iron molecules in the iron pan to rotate at a high speed and generate collision and friction to generate heat and directly heat the food in the pan. [0003] In the prior art, the structure of the induction cooker is generally as follows: it includes a shell and connecting wires, a flat microcrystalline panel is installed on the upper surface of the shell, and the outer surface of the microcrystalline panel is used to place a pan. There is also a planar coil disk, which is closely attached to ...

AI Technical Summary

Problems solved by technology

[0006] 1. In the prior art, since the main control circuit board and the coil disk are all arranged inside the same housing, even if the heat dissipation fan can dissipate part of the heat generated when the induction cooker is working, the heat dissipation effect is not ideal;

[0007] 2. The coil disk of the induction cooker is a device that generates an electromagnetic field. The existing coil disks are made of tightly coiled multi-strand wires. The outer surface of each strand is coated with a coating. When the coil disk is energized, heat will be generated. , the general temperature can reach 200°C-300°C, such tightly coiled multi-strand wires coated with coating on the outer surface have poor heat dissipation effect, and the temperature of 200°C-300°C may melt the coating and strands, causing accidents , which makes it necessary to install a cooling fan in the existing induction cooker, otherwise it cannot be used

[0008] 3. In the prior art, the stove mechanism of the induction cooker is equipped with multiple sub-cookers. When there are multiple sub-cookers working at the same time, the main mechanism of the induction cooker cannot reasonably distribute the output power of the coil disk in each sub-cooker body.

[0009] 4. In the prior art, the connecting wires connected to the input end of the host usually have different cross-sectional areas, so the maximum power that the connecting wires can withstand of the induction cooker is also different. In this way, once the normal working power of the induction cooker is adjusted to be greater than the When the maximum power that the line can withstand, the connecting line is easily burned or melted due to excessive input current
