Title:
ELECTROMAGNETIC HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/253862
Kind Code:
A1
Abstract:
Provided is an electromagnetic heating device (100), comprising a light-transmitting panel (1) configured to bear an instrument (2) to be heated, a heating coil (3) provided below the light-transmitting panel (1) and configured to generate an electromagnetic field so as to heat said instrument (2), a temperature measurement assembly and an emission measurement assembly. The temperature measurement assembly comprises a second infrared detector (5) provided below the light-transmitting panel (1) and configured to receive second infrared rays (7) emitted by the light-transmitting panel (1) and said instrument (2). The emission measurement assembly comprises an infrared emitter (10) and a third infrared detector (11) which are provided below the light-transmitting panel (1); the infrared emitter (10) is configured to emit third infrared rays (12) in a third wavelength range to said instrument (2), and the third infrared detector (11) is configured to receive third reflected rays (13) obtained after the third infrared rays (12) are reflected by said instrument (2). By means of the arrangement of the emission measurement assembly, the infrared reflectivity of the surface of said instrument (2) is measured in real time, and then when the temperature of said instrument (2) is measured, the effect of the infrared reflectivity of the surface thereof is considered.
