WATER LEAKAGE DETECTION DEVICE
PROBLEM TO BE SOLVED: To provide a water leakage detection device capable of detecting water leakage with a simple configuration.SOLUTION: A water leakage detection device 100 comprises: a (solenoid) valve 1 which opens and closes a water channel from a water supply port P1 to a water discharge port P2; a heater 2 which is installed in the water channel; a first temperature sensor 3 which detects a temperature in the water channel at an upstream side of the heater 2 close to the water supply port; a second temperature sensor 4 which detects the temperature in the water channel at a downstream side of the heater 2 close to the water discharge port; and a control section 6 which can control the valve, detects water leakage in the water channel on the basis of a difference between detection results of the first temperature sensor and the second temperature sensor and causes the valve to close the water channel when detecting an occurrence of the water leakage.SELECTED DRAWING: Figure 1
【課題】簡単な構成で漏水を検知することができる漏水検知装置を提供する。【解決手段】漏水検知装置１００は、給水口Ｐ１から吐水口Ｐ２までの水の流路を開閉する（電磁）弁１と、流路上に設けられるヒータ２と、ヒータ２に対して給水口側の流路内の温度を検出する第１温度センサ３と、ヒータに対して吐水口側の流路内の温度を検出する第２温度センサ４と、弁を制御可能に構成され、第１温度センサと第２温度センサとの検出結果の差分に基づいて流路上の漏水の有無を検知し、漏水の発生を検知した場合に弁に流路を閉じさせる制御部６とを備える。【選択図】図１
