Zusammenfassung:To provide a washing machine that is hardly influenced with regard to fluctuation in a liquid level to be measured and enables a stable detection of the liquid level.SOLUTION: The washing machine comprises a tank for storing a washing liquid, a tank tray for accommodating the tank, and remaining amount detection means for detecting a remaining amount of the washing liquid. The remaining amount detection means comprises a float provided with a magnet, and a magnetic sensor arranged at a bottom back of the tank and a bottom of the tank tray. The magnetic sensor detects the magnet in a non-contact manner with the magnetic sensor to detect a remaining amount of the washing liquid. The float is movable with a liquid level of the washing liquid by a hinge connected to the tank. The magnet is arranged in such a manner that either of magnetic poles faces a magnetic sensor side with the float being positioned at a lowest part in a movable range.SELECTED DRAWING: Figure 6 【課題】測定対象とする液面の変動に対する影響を受けにくく、安定した液面検知が可能な洗濯機を提供する。【解決手段】洗濯液を格納するタンクと、タンクを収納するタンクトレイと、洗濯液の残量を検知する残量検知手段と、を有し、残量検知手段は、磁石を備えたフロートと、タンクの底裏、且つタンクトレイ底部に設けた磁気センサを有し、磁気センサは、磁気センサと非接触で磁石を検知して洗濯液の残量を検知し、フロートは、タンクに接続されたヒンジにより、洗濯液の液面に伴い移動可能とし、磁石は、フロートが可動範囲の最下部に位置した状態において、磁気センサ側に磁極のどちらかが向き合う配置とした構成とする。【選択図】 図6
