An automatic, water dispensing, filter shutoff device having a disposable and replaceable filter. The shutoff device is in removable engagement and fluid communication with a water container such as a water bottle, and is adapted to disable dispensing after a predetermined amount of dispensing has occurred, which may but need not substantially correspond to the filtration capacity of the filter. In a preferred embodiment, the shutoff device includes a monitoring and disabling with plunger components moveable between dispensing and disabling locations, and a rotating indexing mechanism. At the disabling location, a plunger component is placed in an interfering position with the engagement between the shutoff device and the water container. The shutoff device can distinguish between water bottles having different volumetric capacities, and terminate dispensing accordingly. Preferable, a replaceable filter cartridge is provided which, when removed, causes the indexing mechanism to be reset.

Bottled water dispenser with shutoff, variable filtration capacity and replaceable cartridge filter

A compact, countertop water dispenser preferably dispensing ambient, chilled or hot water, and preferably allowing single-hand dispensing of ambient and child water, as well as child-resistant hot water dispensing. In one embodiment, powered by thermoelectrics, a side-mounted water container feeds a first reservoir, which feeds a second reservoir in liquid communication with hot and cold tanks. Predetermined reservoir water levels may be maintained by float switches and solenoid valves may be used to enable/disable water flow from the tanks and dispensing. Many other features are provided as described below.
