Bottom load water cooler

A water cooler with an adjustable drip tray assembly having a leakage compartment for storing spilled liquid, and providing a support surface for supporting a vessel to be filled with liquid, the adjustable drip tray assembly being capable of moving between a retracted position providing a first support surface for supporting conventional-sized vessels, and an extended position providing a second, enlarged support surface for supporting substantially larger vessels than when the adjustable drip tray assembly is in the retracted position.

A liquid dispensing apparatus enabling a conventional dispensing mode in which liquid is dispensed as long as a user depresses a button or lever, and a measured fill dispensing mode permitting the user to preselect a predetermined volume of liquid to be dispensed.

A liquid dispensing mechanism comprising a supporting frame and a liquid-containing bottle in fluid communication with a dispensing mechanism, a neck of the bottle interfacing with a cap and a hollow probe with a bottle guide, the bottle guide supporting the bottle, and the cap and hollow probe enabling liquid to flow from the bottle to the dispensing mechanism, further comprising a leak stop seal having sealing surfaces creating liquid-tight seals between the bottle guide and the cap at the sealing surfaces, wherein a tight seal is created by the weight of the water bottle pressing down on the sealing surfaces.

A water cooler assembly comprising a supporting frame carrying bottle retaining members and a water bottle in fluid communication with a dispensing mechanism, a neck of the water bottle interfacing with a cap and a hollow probe with a bottle guide, the bottle guide supporting the water bottle, and the cap and hollow probe enabling water to flow from the water bottle to the dispensing mechanism, wherein the bottle guide and hollow probe are movable with respect to the bottle retaining members to accommodate dimensional variations of different water bottles.

A water cooler supplied with a source of water comprising either a pressurized outside water source or a water bottle, the water cooler comprising cold and hot tanks for selectively providing cold or hot water, the cold tank include a baffle, wherein an instaboil dispensing mode may be selectively enabled, wherein water in the hot tank is heated to a near-boil and is dispensed, and wherein further heating of the hot tank is stopped, based on feedback from a temperature sensor located on or near the baffle of the cold tank.

A liquid dispensing apparatus enabling dispensing of hot or cold liquids in a first dispensing mode, selectively enabling all dispensing to be prevented in a second dispensing mode, selectively enabling dispensing of hot liquids to be prevented in a third dispensing mode, and visually displaying the selected dispensing mode.
