an electromagnetic cooker

Abstract

An electromagnetic cooker, comprising a glass panel (1), at least one thermistor (2) and a conductive ink layer (3) being arranged on a surface of a heating area of the glass panel (1); one end of the conductive ink layer (3) is connected to a thermistor (2), and the other end is connected to a control circuit of an electromagnetic cooker; an insulating ink layer (4) is arranged on the thermistor (2) and the conductive ink layer (3); the insulating ink layer (4) covers the thermistor (2) and the conductive ink layer (3) so that the thermistor (2) and the conductive ink layer (3) are not exposed. The electromagnetic cooker carries out direct temperature measurement, reduces temperature measurement error and hysteresis effect, and may aid a user in controlling heat in a timely manner.

Description

technical field [0001] The present invention relates to the technical field of electromagnetic cooktops, and more specifically, to an electromagnetic cooktop. Background technique [0002] When the induction cooker is working, the utensils on the induction cooker will heat themselves. For the temperature change of the induction cooker to monitor the utensils, it is generally realized by a temperature controller installed at the bottom of the glass-ceramic plate, and the heat is transmitted through the micro-crystalline plate. The thermostat will produce hysteresis and there is a temperature difference, so it is difficult to monitor the temperature of the vessel in real time. [0003] At present, the temperature measurement methods of electromagnetic cookers usually include: 1. Install an NTC (thermistor) on the bottom of the glass panel, that is, inside the machine. The NTC touches the bottom of the glass panel to measure the temperature of the inner surface of the glass pan...

[0002] When the induction cooker is working, the utensils on the induction cooker will heat themselves. For the temperature change of the induction cooker to monitor the utensils, it is generally realized by a temperature controller installed at the bottom of the glass-ceramic plate, and the heat is transmitted through the micro-crystalline plate. The thermostat will produce hysteresis and there is a temperature difference, it is difficult to monitor the temperature of the vessel in real time

[0003] At present, the temperature measurement methods of electromagnetic cookers usually include: 1. Install an NTC (thermistor) on the bottom of the glass panel, that is, inside the machine. The NTC touches the bottom of the glass panel to measure the temperature of the inner surface of the glass panel; The temperature element is located on the bottom of the glass panel, which is also inside the machine. By receiving the infrared light passing through the glass panel, it can identify the temperature of the object that emits or refracts the infrared light. These temperature measurement schemes have more or less the difference between the measured value and the actual value. Due to the temperature difference and hysteresis effect, the temperature measurement technology of induction cooker products cannot keep up with the functional development requirements of induction cooker products, and most of the functions that require precise temperature control cannot be realized.
