PROBLEM TO BE SOLVED: To provide a liquid supply device capable of supplying water in a tank by raising a contact part with a valve opening/closing mechanism.SOLUTION: An outflow port 27 is opened by a valve opening/closing mechanism 35 at the time of starting mist operation and closed by the valve opening/closing mechanism 35 at the time of stopping the mist operation, and thus only water in a water storage chamber 6 and a storage part 10 can be flowed into a waste liquid tray 24 without removing a tank 7 from a tank mounting part 9. This prevents the water from overflowing from the waste liquid tray 24 and improves use feeling without removing the tank 7 from a device body 1 when discharging the water in the water storage chamber 6 and the storage part 10. Furthermore, since the valve opening/closing mechanism 35 for raising a valve body 26 provided in the tank 7 is absent in the storage part 10, it is possible to prevent long-term deterioration of the valve opening/closing mechanism 35 due to a substance such as chlorine contained in the water accumulated in the storage part 10, and operate the valve opening/closing mechanism 35 reliably for a long period of time.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2016,JPO&INPIT【課題】 弁開閉機構により当接部を上昇させてタンク内の水を供給可能な液体供給装置を提供する。【解決手段】 ミスト運転開始時に弁開閉機構35により流出口27を開口させ、ミスト運転停止時に弁開閉機構35により流出口27を閉止させるので、タンク装着部9からタンク7を抜くことなく貯水室6及び貯留部10内の水のみを廃液トレー24へ流入させることができるため、貯水室6及び貯留部10内の水を排水する時にタンク7を器具本体1内から取り出す作業をせずとも廃液トレー24から水が溢れ出すことがなく使用感が向上し、また、タンク7に備えられた弁体26を上昇させる弁開閉機構35が貯留部10内に存在しないため、貯留部10内に溜まった水に含まれるカルキ等の物質による弁開閉機構35の経年劣化が発生せず、弁開閉機構35を長期に渡り確実に作動させることができる。【選択図】 図5
