項１記載の調理器具用火力表示装置。[Scope of Claim for Utility Model Registration] (1) It is claimed that the cooking utensil is equipped with a fire power detection means that is linked to the heat power adjustment, and a display means that changes the display color in stages according to the fire power detected by the fire power detection means. Features: A firepower display device for cooking utensils. (2) The display means includes at least two light emitting elements having different emission colors, and display means is provided in which the respective emission colors are mixed.
The thermal power detection means includes a variable resistor whose resistance value changes in conjunction with the thermal power adjustment operation, and a threshold value that discriminates the voltage that increases or decreases in response to the increase or decrease in the resistance value of the variable resistor using multiple threshold values. a comparison circuit that generates an output voltage according to the output voltage; and a first comparator circuit that drives one of the light emitting elements with a drive current that corresponds to the increase or decrease in the output voltage.
2. A cooking utensil according to claim 1, further comprising: a driving means; and a second driving means for driving the other light emitting element by decreasing and increasing a driving current in response to an increase or decrease in the output voltage. Firepower display device.
