とする天ぷら鍋用温度表示装置。 A tempura dish that consists of a sensor rod that detects the temperature of the oil in the deep fryer using a thermistor attached to the bottom end, and a main circuit case that houses the main circuit on the top of the sensor rod that displays and reports the oil temperature detected by the sensor rod. In the temperature sensor for a pot, LEDs L 1 , L 2 ,...L are arranged in multiple stages on the case surface of the main body case.
n, and the respective LEDs L 1 , L 2 ,...L
Temperature values corresponding to the oil temperature when the respective LEDs are turned on are displayed in parallel on n, and the oil temperature rises due to the negative temperature characteristic of the resistance value of the thermistor in the main circuit, and the resistance value of the thermistor decreases. A comparator A is provided with a sensor amplifier that amplifies the changing power supply sharing voltage, and inputs the output of this sensor amplifier to reference voltages E 1 , E 2 , ... En of multi-step sizes, respectively.
1 , A 2 , ...An, and connect the respective comparators A 1 , A 2 , ...An to the LEDs L 1 , L 2 , ...Ln displayed on the main body case surface, and connect at least the highest oil A notification device such as a buzzer is connected to the comparator An that inputs the reference voltage En that operates when the oil temperature is high, and as the oil temperature rises, the LEDL1
, L2 , .
