摘要： A dishwasher is provided with a fluid handling system that utilizes two separate sumps and two separate pumps. A first sump receives a portion of the wash liquid from the wash chamber and recirculates the wash liquid by use of a relatively high capacity pump in the first sump. The second sump receives the remainder of the wash liquid and removes both heavier-than-water and lighter-than-water soils before directing this remainder of the wash liquid to the first sump. A relatively low capacity pump in the second sump directs wash liquid and collected soils to an exterior drain.

摘要： A vacuum cleaner includes a floor cleaning unit having a rotatable brush driven by a brush motor and a receptacle for collecting particulate matter. The floor cleaning unit is mechanically and pneumatically interconnected with the receptacle through a rigid wand and a wand handle and hose assembly. The wand handle and hose assembly includes a wand handle, disposed between the rigid wand and a flexible hose. The wand handle includes a passage through which air and particulate matter pass from the floor cleaning unit to the receptable. A corona discharge element with a roughened surface is positioned in the downstream end of the wand handle passage. A stub tube is positioned in the upstream end of the wand handle passage to connect the wand handle to the wand. A conductive strap, installed in the wand handle using a heat staking process, interconnects the stub tube and the corona discharge element. During the operation of the vacuum cleaner, any electrostatic charge that has accumulated on the wand will migrate to the roughened surface of the corona discharge element and will be dissipated or drained off by a corona discharge into the air flowing through the wand handle.
摘要翻译： 真空吸尘器包括具有由刷马达驱动的可旋转刷的地板清洁单元和用于收集颗粒物质的容器。 地板清洁单元通过刚性棒和杆把手和软管组件与容器机械地和气动地互连。 手柄和软管组件包括设置在刚性棒和柔性软管之间的棒柄。 魔杖手柄包括一个通道，空气和颗粒物质通过该通道从地板清洁单元传递到容器。 具有粗糙表面的电晕放电元件位于魔杖手柄通道的下游端。 短管被定位在魔杖手柄通道的上游端，以将魔杖手柄连接到魔杖。 使用热铆接工艺安装在手柄中的导电带将短截线管和电晕放电元件相互连接。 在真空吸尘器的操作期间，积聚在杖上的任何静电电荷将迁移到电晕放电元件的粗糙表面，并且通过电晕放电而消散或排出流入通过该把手的空气中。

摘要： Structure for converting a powered brush vacuum cleaner selectively to define a powder carpet cleaning apparatus. The conversion structure includes a shroud received within the nozzle. In one form, the shroud is movably mounted within the nozzle for selective disposition in a retracted position, permitting use of the nozzle in the normal vacuum cleaning manner, and in an operative position blocking the entrance to the suction passage for permitting the unit to be used as powder carpet cleaner. The shroud defines a smooth inner surface surrounding a portion of the brush for effectively preventing clogging of the brush during the carpet cleaning operation. An opening is provided in the nozzle wall for access to the movable shroud in effecting manipulation thereof between the retracted and operative positions. In another form, the shroud is fixedly mounted within the nozzle and a closure is removably installed for closing the entrance to the suction passage when it is desired to use the unit as a carpet cleaner. In the illustrated embodiment, the closure includes a tongue received in a socket portion of the shroud in the installed arrangement. Provisions are made for accommodating bridging elements extending across the nozzle opening when necessary.

摘要： An electric control for a water conditioning system includes a solenoid valve which controls water inlet into the system and which is controlled by a flow switch that senses product water flow from a water faucet or other outlet. The flow switch also energizes an indicator lamp for indicating processing of water. The flow switch also controls a second solenoid valve which allows water flow into the pressure or "squeeze" side of a bladder type product water storage tank. When product water flow occurs, the second solenoid valve opens to permit supply water to flow therein, providing additional pressure to the product water side of the storage tank. Accordingly, product water flow is effected from the storage tank to the product water outlet. When a predetermined low pressure is sensed, a pressure switch located on the product water side of the storage tank opens the first solenoid valve to supply water to the system for processing. Also, the solenoid valve which provides squeeze water to the storage tank is closed, thereby permitting product water to flow into the storage tank and accumulator. When a predetermined high pressure is sensed by the pressure switch, the first solenoid valve is closed to terminate water processing, until product water flow is again sensed.
摘要翻译： 用于水处理系统的电控装置包括一个电磁阀，它控制进入系统的进水口，并由一个感应从水龙头或其它出口产生的产品水流的流量开关控制。 流量开关还给指示灯供电以指示水的处理。 流量开关还控制第二电磁阀，其允许水流入膀胱式产品储水箱的压力或“挤压”侧。 当发生产品水流时，第二电磁阀打开以允许供水在其中流动，为储罐的产品水侧提供额外的压力。 因此，产品水流从储罐到产品出水口进行。 当检测到预定的低压时，位于储罐的产品水侧的压力开关打开第一电磁阀，以向系统供水以进行处理。 此外，向储罐提供挤压水的电磁阀关闭，从而允许产品水流入储罐和蓄能器。 当由压力开关感测到预定的高压时，第一电磁阀关闭以终止水处理，直到再次感测到产品水流。

摘要： A soil separator for a dishwasher is provided in which the recirculating wash liquid flow through the dishwasher is divided into two flow streams and the soil separator is positioned in one of the flow streams. A screen blocks passage of large soil particles and directs then into the flow stream leading to the soil separator. An elevated dam in the soil separator blocks passage of lighter-than-water particles and a weir blocks passage of heavier-than-water particles. A V-shaped notch in the weir permits flow from the soil separator to rejoin the other flow stream.
