US 2025/0168940 A1 · INDUCTION HEATER AND CONTROLLING METHOD THEREOF

Abstract

An induction heating apparatus includes: a first heating portion including a single heating coil; a second heating portion including an inner heating coil and an outer heating coil; and a controller configured to control an operation of the first heating portion and an operation of the second heating portion. A maximum output frequency of an operation of the single heating coil is configured to be set higher than a maximum output frequency of a single operation of the inner heating coil of the second heating portion, and the maximum output frequency of the operation of the single heating coil is configured to be set lower than a maximum output frequency of simultaneous operations of the inner heating coil and the outer heating coil.

wherein a maximum output frequency of an operation of the single heating coil is configured to be set higher than a maximum output frequency of a single operation of the inner heating coil of the second heating portion, and the maximum output frequency of the operation of the single heating coil is configured to be set lower than a maximum output frequency of simultaneous operations of the inner heating coil and the outer heating coil.

2 more elements

A method for controlling an induction heating apparatus comprising a first heating portion including a single heating coil, and a second heating portion including an inner heating coil and an outer heating coil, the method comprising:

setting a maximum output frequency of the single heating coil to be higher than a maximum output frequency based on a single operation of the inner heating coil, and lower than a maximum output frequency of simultaneous operations of the inner heating coil and the outer heating coil;
and
in response to simultaneously operating the single heating coil and the inner heating coil, changing the maximum output frequency of the operation of the single heating coil to be identical to the maximum output frequency of the single operation of the inner heating coil.
