    • A carpet extractor includes a base assembly (1) including a housing (10) which selectively receives a recovery tank (22) for collecting dirty cleaning fluid. A first supply tank (14) for concentrated cleaning fluid and a second supply tank (15) for clean water are mounted on an inverted Y-shaped handle assembly (12). The handle assembly (12) includes a central member (334) with a hand grip (336) at its upper end and two splayed leg members (338,342,340,344), which define a triangular shaped gap therebetween. The two tanks (14,15) are removably mounted in the gap. The cleaning fluid tank (14) is supported on a shelf (346), which spans the gap between the leg members (338,342,340,344). The water tank (15) is pivotally mounted on two projections (374) on the leg members (338,342,340,344) to allow for easy removal and replacement on the handle (12). The arrangement of tanks (14,15) in the gap allows for large capacity tanks, a well-balanced handle (12), ease of removal of the recovery tank (22) without the need for removing either of the two supply tanks (14,15), and ease of refill of the supply tanks (14,15).
    • 地毯提取器包括基座组件(1),该基座组件包括壳体(10),壳体(10)选择性地接收用于收集脏清洁流体的回收罐(22)。 倒Y形手柄组件(12)上安装有用于浓缩清洁液的第一供应罐(14)和用于清洁水的第二供应罐(15)。 手柄组件(12)包括中央部件(334),该中央部件在其上端具有手柄(336)以及两个张开的支腿部件(338,342,340,344),所述支腿部件在其间限定三角形间隙。 两个罐(14,15)可拆卸地安装在间隙中。 清洁液罐(14)支撑在架子(346)上,架子跨越腿部件(338,342,340,344)之间的间隙。 水箱(15)可枢转地安装在腿构件(338,342,340,344)上的两个突出部(374)上,以允许在手柄(12)上方便地移除和更换。 将槽(14,15)布置在间隙中允许大容量罐,平衡良好的手柄​​(12),易于移除回收罐(22)而无需移除两个供应罐(14 ,15),以及供应罐(14,15)的再填充容易。

    • An automatic discharge assembly (32) for use with vacuum cleaner (10) is disclosed. The vacuum cleaner (10) has a tank (12) defining an interior having an inlet (24) for receiving liquid material and an outlet (30) for discharging liquid materials, and a vacuum source (16,18) for selectively generating a partial vacuum in the tank interior. The automatic discharge assembly (32) comprises a valve housing (42) defining a liquid discharge path having an inlet (44) adapted for fluid communication with the tank outlet (30) and an outlet (46) for directing liquid material discharge. A pressure-responsive flapper valve (50) is pivotably connected to the valve housing (42), the flapper valve (50) being moveable between a closed position, in which the flapper valve (50) obstructs the liquid discharge path (49), and an open position, in which the flapper valve (50) allows fluid flow through the liquid discharge path (49). The flapper valve (50) moves to the closed position when vacuum is present in the tank interior, and to the open position under a mass force of the liquid material inside the tank (12) when a pressure in the tank interior is substantially the same as an atmospheric pressure outside the tank (12).
    • 公开了一种用于真空吸尘器(10)的自动排放组件(32)。 真空吸尘器(10)具有限定具有用于接收液体材料的入口(24)和用于排出液体材料的出口(30)的内​​部的罐(12),以及用于选择性地产生部分 在坦克内部真空。 自动排放组件(32)包括限定具有适于与罐出口(30)流体连通的入口(44)和用于引导液体材料排放的出口(46)的液体排出路径的阀壳体(42)。 压力响应挡板阀(50)可枢转地连接到阀壳体(42)上,挡板阀(50)可在挡板阀(50)阻挡液体排出通道(49)的关闭位置之间移动, 以及打开位置,其中挡板阀(50)允许流体流过液体排出路径(49)。 当罐内部的压力基本相同时,挡板阀(50)在罐内部存在真空并且在罐(12)内的液体材料的质量力下移动到打开位置时移动到关闭位置 作为罐(12)外的大气压。
