Problems solved by technology

However, because the thermal conductivity of ceramics is worse than that of iron pots used in ordinary induction cookers, when the electromagnetically heated ceramic pot is dry-fired without water, the temperature at the bottom of the ceramic pot will rise quickly to exceed 500°C, which will crack the ceramic pot and cause damage to the ceramic pot
This severely limits the use of electromagnetically heated ceramic pans

Abstract

The invention relates to electrical appliance optimization, and discloses a cooking appliance anti-dry-burning method. The method includes detecting first temperature t1 of the appliance pot bottom atfirst time T1; detecting second temperature t2 of the appliance pot bottom at second time T2 after the first time; calculating temperature difference Deltat0 between the first temperature t1 and thesecond temperature t2; determining first temperature rise slope K1 and a first temperature threshold t3 according to the temperature difference Deltat0 and mass m of liquid in a cooking appliance; when the temperature of the appliance pot bottom is greater than the first temperature threshold t3 and / or the temperature rise slope is greater than the first temperature rise slope K1 within predetermined time, stopping outputting power to stop heating. The cooking appliance anti-dry-burning method, a device and a cooking system can detect whether the cooking appliance is burned, and protect an electromagnetic heating ceramic pot from damage.

Description

technical field [0001] The invention relates to the optimization of electric appliances, in particular to a cooking appliance anti-dry method, device and cooking system. Background technique [0002] Now the temperature sensors of the induction cooker are all installed on the lower surface of the microcrystalline plate at the pot position. A 4mm thick glass-ceramic panel is separated between the pot temperature detection sensor and the pot, and the temperature sensor does not directly detect the temperature of the pot. When the induction cooker is heated, the pot senses the electromagnetic field generated by the system composed of the main control board of the induction cooker and the induction coil plate, and generates eddy current at the bottom of the pot, thereby generating heat. The heat is then conducted through the microcrystalline panel to the temperature sensor below. In this indirect temperature measurement method, the detected temperature value of the pot has obv...
