PURPOSE:To enable even for little children, old people and the like to know the proper temperature by a method wherein the sound-producing temperature of a sounding body, which produces sound by means of a sensor to sense the water temperature raised by solar heat, and the light-emitting temperature of a lamp, which emits light by means of said sensor, are made variable. CONSTITUTION:When a hot water temperature check button 2 is depressed, a hot water temperature check circuit 7 powered by a cell 5 senses the hot water temperature with a signal sent from a thermistor 8 and swings the pointer of a meter 9 in accordance with the hot water temperature. In addition, a ''buzzer ON'' circuit 14 causes a buzzer 12 to produce sound by oscillating a buzzer oscillation circuit 13 based upon the signal sent from the thermistor 8 and the set value set by a setting variable resistor 27. Further, a ''lamp ON'' circuit 16 causes a lamp 15 to emit light based upon the signal sent from the thermistor 8 and the set value set by the setting variable resistor 27. Thus, even a person, to whom the precise reading of the meter is difficult, can precisely confirm the temperature with eyes and ears. |
