AI Technical Summary

Technical Problem

Existing induction cookers are incompatible with different cookware, especially flat-bottomed cookware, resulting in poor heating or failure to heat properly. Furthermore, the fixed curvature of concave induction cookers makes it difficult to be compatible with cookware that does not have a matching curvature.

Method used

Design a coil plate including a magnetic strip assembly, an upper winding assembly and a lower winding assembly. By setting an extension and different circuit designs for the magnetic field direction, the magnetic field is enhanced on the pot wall, thereby improving compatibility performance.

Benefits of technology

It enhances the heating effect of the pot wall, improves compatibility with different cookware, and increases heating efficiency and electromagnetic compatibility.

Abstract

The application provides a coil panel, a heating assembly and a cooking appliance. The coil panel comprises a magnetic strip assembly, an upper winding assembly and a lower winding assembly. The magnetic strip assembly comprises a plurality of magnetic strips. Each magnetic strip comprises a main body portion and an extension portion. One end of the extension portion is connected to the main body portion. The other end of the extension portion extends away from the main body portion on a first side. The upper winding assembly is a powered circuit. The upper winding assembly is arranged on the first side of the magnetic strip assembly. The extension portion is located outside the upper winding assembly. The lower winding assembly is a non-powered circuit. The lower winding assembly is arranged on a second side of the magnetic strip assembly. The upper winding assembly generates a first magnetic field in a powered state and the first magnetic field acts on the lower winding assembly. The lower winding assembly generates a second magnetic field after generating a reverse current. The magnetic field directions of the first magnetic field and the second magnetic field are opposite in the circumferential direction of the coil panel. The magnetic field directions of the first magnetic field and the second magnetic field on the magnetic strip are the same. The coil panel can improve the compatibility when different pots are heated.
