Problems solved by technology

[0002] Most of the existing coil disks are single-coil structures, and their inductance does not change during the working process. Under low-power working conditions, if the freewheeling current is insufficient, the insulated gate bipolar transistor (IGBT for short) will be turned on ahead of time, which is easy to Cause overcurrent or overheating breakdown, which seriously affects the safety and service life of the induction cooker. It is difficult to achieve full-power heating, and it is impossible to complete low-power continuous heating. If the coil plate uses intermittent heating to achieve low-power work, it will affect cooking. effect, there is room for improvement

Abstract

The invention discloses a coil panel and an electromagnetic oven provide with the same. The coil panel comprises a support, a first coil and a second coil, wherein the fist coil is installed on the support; and the second coil is installed on the support, the second coil is connected with the first coil in series, and the inductance of the first coil is less than the inductance of the second coil. The coil panel disclosed by the invention can operate continuously at a low-power state.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a coil disk and an electromagnetic cooker with the coil disk. Background technique [0002] Most of the existing coil disks are single-coil structures, and their inductance does not change during the working process. Under low-power working conditions, if the freewheeling current is insufficient, the insulated gate bipolar transistor (IGBT for short) will be turned on ahead of time, which is easy to Cause overcurrent or overheating breakdown, which seriously affects the safety and service life of the induction cooker. It is difficult to achieve full-power heating, and it is impossible to complete low-power continuous heating. If the coil plate uses intermittent heating to achieve low-power work, it will affect cooking. effect, there is room for improvement. Contents of the invention [0003] The present invention aims to solve one of the technical problems in th...
