Description

上記目的を達成するために請求項１記載の発明は、溜水を蓄えて使用者の排泄物を受けるボウルを備えた大便器と、上端を大気解放端とした立管状の水位形成管と、前記水位形成管内の水位によって生じる圧力を測定する圧力計測手段と、前記水位形成管の下端部と前記ボウル内の溜水とを連通し前記測定水位形成管内に前記溜水の水位と同一水位の測定水位を形成する測定水位形成手段と、前記測定水位における前記圧力計測手段によって計測される圧力計測値に基づいて前記溜水の水位を算出する溜水水位算出手段と、前記水位形成管に給水し前記水位形成管内に所定の高さの校正水位を形成する校正水位形成手段と、前記校正水位における前記圧力計測手段の出力値に基づいて前記圧力計測手段の出力を校正する出力校正手段と、待機状態において測定開始操作があると、前記圧力計測手段、前記測定水位形成手段、前記溜水水位算出手段、前記校正水位形成手段、及び、前記出力校正手段を用いて前記溜水の水位を測定する測定動作を実行する制御処理部と、を有する水位測定装置において、前記校正水位形成手段に、前記測定動作を実行していない前記待機状態における所定のタイミングで、前記校正水位を再形成するリフレッシュ動作を行なわせるリフレッシュ動作制御手段をさらに備えたことを特徴とすることにより、圧力測定手段の出力校正動作において基準となる校正水位が更新されて常に許容範囲内の水位に保たれることとなることで、圧力測定手段の出力校正を正確に行なうことが可能となるため、便器ボウル内の溜水水位の測定精度が低下することが無くなる。
In order to achieve the above object, the invention described in claim 1 includes a toilet having a bowl for storing stored water and receiving user's excrement, a vertical tubular water level forming pipe having an upper end as an open air end, A pressure measuring means for measuring a pressure generated by the water level in the water level forming pipe, a lower end portion of the water level forming pipe and the stored water in the bowl are communicated, and the water level of the stored water is the same as the level of the stored water A measuring water level forming means for forming a measuring water level; a stored water level calculating means for calculating the water level of the stored water based on a pressure measurement value measured by the pressure measuring means at the measuring water level; and water supply to the water level forming pipe Calibration water level forming means for forming a calibration water level of a predetermined height in the water level forming pipe, output calibration means for calibrating the output of the pressure measuring means based on the output value of the pressure measuring means at the calibration water level, Wait If there is a measurement start operation in the state, the water level is measured using the pressure measuring means, the measurement water level forming means, the stored water level calculating means, the calibration water level forming means, and the output calibration means. A refresh operation for re-forming the calibration water level at a predetermined timing in the standby state in which the measurement operation is not performed in the calibration water level forming means in a water level measurement device having a control processing unit for performing a measurement operation by, further comprising a refresh operation control hand stage to perform, so that the calibration level to be a reference at the output calibration operation of the pressure measuring means is kept water level in the always allowable range is updated This makes it possible to accurately calibrate the output of the pressure measuring means, so that the accuracy of measuring the water level in the toilet bowl is not reduced. That.
