Abstract

The invention discloses an induction cooker. The induction cooker comprises an electromagnetic coil disc assembly and an induction cooker main control panel assembly arranged on one side of the electromagnetic coil disc assembly, and further comprises multiple heat pipes, heat radiation assemblies and heat radiation fans. The heat radiation assemblies are symmetrically arranged on the two sides of the electromagnetic coil disc assembly. Each heat radiation assembly comprises a heat radiation base body and heat radiation wings. A cavity is formed in each heat radiation base body. One end of each heat radiation wing communicates with the corresponding cavity. Multiple grooves are formed in the positions, opposite to the corresponding heat radiation wings, of each heat radiation base body. The heat pipes are fixed in the grooves. The other end of each heat pipe is fixedly connected to the electromagnetic coil disc assembly. Each heat radiation fan is arranged on one side of the corresponding heat radiation assembly. By means of the multiple heat pipes, heat is fast conducted into the heat radiation base bodies of the heat radiation assemblies; and due to the fact that each heat radiation base body is provided with the cavity, the specific surface area of the heat radiation assemblies is increased, and heat is fast discharged through the heat radiation assemblies under the action of the heat radiation fans.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an electromagnetic cooker. Background technique [0002] Induction cooker is a commonly used kitchen appliance. Its principle is the phenomenon of electromagnetic induction: using alternating current to generate an alternating magnetic field whose direction is constantly changing through the coil, eddy current will appear inside the conductor in the alternating magnetic field, which is eddy current. The electric field promotes the movement of carriers in the conductor; the Joule heating effect of the eddy current makes the conductor warm up, thereby realizing heating. [0003] In the existing heat dissipation device of the induction cooker, the coil plate of the induction cooker or the main control board is directly connected to the heat sink for heat dissipation, and the assembly position of the heat sink is limited by the assembly position of the power tube and the rectifier...
