Cooking appliances and their coil pans

Abstract

The invention provides a cooking appliance and a coil disk thereof. Wherein, the coil disk includes: a disk base and at least 30 columnar magnets, and a multi-ring heating coil is wound on the disk base; The disk surface is evenly distributed along the winding path of the heating coil, and at least 30 columnar magnets are located in the winding interval of the heating coil. The coil disk provided by the present invention uniformly distributes a plurality of columnar magnets along the winding path of the heating coil on the disk surface of the disk base, and the area of ​​a single columnar magnet is small and the number of columnar magnets is large, so that the traditional area block is heated and transformed It is heated evenly at multiple points, so that the firepower is very uniform during the cooking process, which effectively avoids the situation of burning the bottom of the pot in some areas when cooking food, effectively improves the cooking effect, and prolongs the service life of the pot.

Description

technical field [0001] The invention relates to the field of kitchen utensils, in particular to a coil disk and a cooking appliance comprising the coil disk. Background technique [0002] At present, the coil disks used in the existing cooking utensils using electromagnetic heating basically use E-shaped or U-shaped magnetic strips for magnetic conduction. The distance between the magnetic stripes in the inner circle is small. Since the magnetic resistance of the magnetic stripe is much smaller than that of the air, the magnetic stripe has a strong convergence effect on the magnetic induction lines, so the magnetic field strength is higher at the position near the magnetic stripe than at the position without the magnetic stripe. , according to the physical definition, the strength of the magnetic field determines the "firepower" of cooking utensils, so the "firepower" at the position where there is a magnetic strip on the coil disk is "high", and the "firepower" is "small" a...

[0002] At present, the coil disks used in the existing cooking utensils using electromagnetic heating basically use E-shaped or U-shaped magnetic strips for magnetic conduction. The distance between the magnetic stripes in the inner circle is small. Since the magnetic resistance of the magnetic stripe is much smaller than that of the air, the magnetic stripe has a strong convergence effect on the magnetic induction lines, so the magnetic field strength is higher at the position near the magnetic stripe than at the position without the magnetic stripe. , according to the physical definition, the strength of the magnetic field determines the "firepower" of cooking utensils, so the "firepower" at the position where there is a magnetic strip on the coil disk is "high", and the "firepower" is "small" at the position without a magnetic strip, and the firepower on the inner circumference is concentrated If the firepower concentration exceeds the outer circumference, the firepower is uneven, and it is easy to burn the bottom of the pot in some areas when cooking food, which not only affects the cooking effect of food, but also affects the service life of the pot
