| description | PROBLEM TO BE SOLVED: To notify that an oil level exceeds a predetermined upper limit at a proper timing by precisely determining whether or not the oil level exceeds the upper limit when the oil level cannot be directly detected by an oil level sensor.SOLUTION: An oil level detection device comprises: an ultrasonic oil level sensor SW9; a characteristic calculation part 10d for calculating an oil lever variation characteristic from when an oil level average value is first calculated until the oil level average value is determined as NG after a line is turned off or oil is changed, on the basis of a detection value of the oil level sensor SW9; a determination part 10f for determining wether or not the oil level average value exceeds a predetermined upper limit on the basis of the oil level variation characteristic calculated by the characteristic calculation part 10d; and an oil lamp 73 for notifying when the determination part 10f determines that the oil level average value exceeds the predetermined upper limit.
【課題】オイルレベルセンサによってオイルレベルを直接、検出できない場合も、オイルレベルが所定の上限値以上になったか正確に判定し、オイルレベルが所定の上限値以上になった旨を適切なタイミングで報知する。【解決手段】オイルレベル検出装置は、超音波式オイルレベルセンサＳＷ９と、オイルレベルセンサＳＷ９の検出値に基づいて、ラインオフ後又はオイル交換後にオイルレベル平均値が最初に算出されてからＮＧ判定されるまでの間におけるオイルレベル変化特性を算出する特性算出部１０ｄと、特性算出部１０ｄにより算出されたオイルレベル変化特性に基づいて、オイルレベル平均値が所定の上限値以上になったか否かを判定する判定部１０ｆと、判定部１０ｆによりオイルレベル平均値が所定の上限値以上になったと判定されたときに、その旨を報知するオイルランプ７３とを備える。【選択図】図２ |
