Problems solved by technology

[0004] The heat dissipation fan used in the traditional induction cooker has a propeller-shaped axial flow fan blade, which is located at the bottom and enters the wind, which can force the wind to be sucked upward into the furnace. , the wind direction is scattered and overflowed, part of it is used for heat dissipation, and a large part is wasted, so the efficiency is low
Therefore, the fan design of the traditional induction cooker has certain disadvantages.

Embodiment Construction

[0023] When implementing, refer to figure 1 As shown, according to the needs of the induction cooker model, it is equipped with a suitable turbo fan. When the bottom shell of the induction cooker is opened, the fixed position, air inlet and wind shielding position of the turbo fan are designed and injection molded together. Press the snail shell frame of the built-in turbo fan with the fan bracket and fix it on the pillar with screws. The air outlet of the large turbo fan is aligned with the heat sink, and the air outlet of the small turbo fan is aligned with resistors, capacitors, transistors, transformers and coil disks. After each electronic component is properly installed, the microcrystalline plate is covered, and the present invention is completed.

Abstract

The invention relates to an electromagnetic furnace with turbine fan, which comprises a micro-crystal plate, a coil disc, a heat radiation plate, the electric devices on the circuit board, and two turbine fans on one end of the bottom. Wherein, the wind outlet of one turbine fan is opposite to the heat radiation plate; the wind outlet of another turbine fan is opposite to the electric devices. The invention uses eccentric diversion while the output airflow is smooth and centralized with less onflows and without blind section. The invention has many blades; therefore, the total projection area on the wind flowing area is larger than the wind flowing area. And via the eccentric effect, it can supply larger wind pressure than the axial flow fan. The better heat radiation system can make the working condition of electromagnetic reach best. The invention can prolong the service life of electromagnetic furnace and reduce the noise.

Description

technical field [0001] The invention relates to an electromagnetic cooker for heating food, in particular to an electromagnetic cooker provided with a turbo fan. Background technique [0002] For a good induction cooker, how well it dissipates heat is very important! Because the induction cooker is a high-power electrical appliance, the temperature in the furnace will rise during the working process, especially the core components of the high-power tube IGBT and the bridge stack, which have strict temperature requirements. If the heat dissipation is poor, the product failure rate will be high and stable. Poor performance, accelerated aging, or even burnt IGBT and bridge stack, which requires a good heat dissipation system, the heat dissipation efficiency largely determines the service life of the induction cooker. [0003] The heat dissipation of the induction cooker adopts air-cooled heat dissipation. The so-called air-cooled radiator, its heat dissipation principle is to ...
