Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a washing machine which detects a small amount of water leakage during an operation without always conducting electricity in water level detection means.SOLUTION: "Soaking", "Tub washing" courses of a fully automatic course have a period in which tub rotation is stopped for a long time while washing water is stored in a water tub 3. When the water level at the start of the period is compared with the current water level, in the case where a water level difference exceeds a preset threshold value, it is determined that there is water leakage. As the tub rotation is stopped in this period, the water level does not fluctuate, and the water levels can be compared accurately. Also, as the water level comparison is conducted for a long period of time, even when the amount of water leakage is small, it can be determined that there is water leakage. Also, water leakage is displayed on operation state display means, and a user can be notified of the water leakage.SELECTED DRAWING: Figure 2
【課題】水位検出手段を常に通電せずに,わずかな漏水を運転中に検知する洗濯機を提供する。【解決手段】全自動コースの「つけおき」「槽洗浄」コースは、水槽3に洗濯水を溜めたまま長期間槽回転を停止した期間を設けており、前記期間の開始時の水位と現在の水位を比較し、水位の差分が予め設定した閾値を超えた場合に、漏水であると判断する。この期間は槽回転は停止しているので、水位が乱れることがなく、正確に水位を比較できるとともに、長期間に渡って水位の比較を行うため、漏水量がわずかであっても漏水と判断できる。また、動作状態表示手段に漏水であることを表示し使用者に報知することができる。【選択図】図2 |
