優れたものにできる。 Since the steam detection sensor is installed in the upper protruding pipe of the water level gauge, the sensor is protected by the protruding pipe and there is no risk of damage.Moreover, the container can be cleaned easily, and the structure is simple. , easy to assemble. In addition, all parts that are constantly exposed to steam can be made of the same material as the container, such as stainless steel, making it highly durable and safe.
蒸気検知用センサーによつて水が完全に沸騰

遮断することができるので、水中の炭酸ガスや
カルキ及びトリハロメタン等を確実に放出でき
る。 After the steam detection sensor detects that the water has completely boiled, the power supply to the heating device can be cut off, so carbon dioxide, chloride, trihalomethane, etc. in the water can be reliably released.
蒸気検知用センサーによる給電制御装置の給
電遮断点を水の沸点より相当低い温度に設定で

給電が遮断され、湯が外部に溢れ出ることもな
く極めて安全性が高い。 Since the power supply cut-off point of the power supply control device using the steam detection sensor can be set to a temperature considerably lower than the boiling point of water, it is possible to always shut off the power supply, and it is also possible to prevent water from entering the container in excess of the rated amount. In this case, the sensor is located below the water surface and detects the water temperature, so the power supply to the heating device is cut off before the boiling point, and the hot water does not overflow outside, making it extremely safe.
