Description

Technical Field

[0001] The invention relates to the field of household electrical appliances, and in particular to a coil disk structure capable of changing the size of a magnetic gap. Background Art

[0002] The structure of an induction cooker includes a base, a coil disk, a panel and a circuit. The coil disk is a power output device and also an energy conversion device. The coil disk transmits energy to the heated dish by electromagnetic induction. The power conversion circuit generates a high-frequency current, which is converted into a high-frequency alternating magnetic field through the coil disk. Under the action of the high-frequency alternating magnetic field, the heated dish generates countless circular currents, causing the heated dish to heat up.

[0003] The coupling coefficient K of the coil disk is related to the size of the magnetic gap (the distance between the coil disk and the pot, that is, the distance between the coil disk and the panel). When the distance between the coil disk and the pot is small, the coupling is tighter, the magnetic leakage is small, and the transmission power is larger. Therefore, when the induction cooker is produced, the fixed height of the coil disk is adjusted according to different needs to change the distance between it and the panel. We know that the coil disk is composed of a coil bracket and an electromagnetic coil. The coil bracket is provided with three or four fixed mounting parts for fixing to the mounting column of the base. During assembly, washers of different thicknesses are placed between the fixed mounting parts and the mounting columns to change the magnetic gap of the coil disk. It is troublesome for assembly workers to install, and it is difficult to improve work efficiency. In addition, the washers need to be allocated on demand according to different specifications, which increases the management burden.

[0004] In view of the above problems, the applicant has proposed a solution. Summary of the invention

[0021] In the present invention, since the installation heights of the installation positions 20 of different groups of installation parts are different, it is determined that when the installation positions 20 of different groups of installation parts are installed on the installation column, the installation heights of the coil disk 10 are different, so that the magnetic gap sizes of the coil disk 10 are different. During installation, the coil disk 10 can be rotated according to the installation needs, and a group of installation parts with a corresponding installation height can be selected.
