Air-circulating base for bottled water cooling and dispensing apparatus
First Claim
1. In water cooling and dispensing apparatus having an insulated chilling tank, and an air circulating fan unit beneath said chilling tank, the improvement comprising:
- an air-circulating base mounted beneath said apparatus having upper and lower generally circular mounting plates, a plurality of vertically extending fins arranged at circumferentially spaced intervals between said mounting plates, means connecting said mounting plates to said fins with said mounting plates disposed in horizontal, spaced parallel relation to one another and with passageways formed between said fins in communication with openings in said upper mounting plates, first and second dividing walls interposed between said plates in diametrically opposed relation to one another and separating said passageways into diametrically opposed inlet ports through which outside air can be drawn upwardly into said apparatus and diametrically opposed outlet ports displaced 90 degrees from said inlet ports through which air can be expelled from said apparatus.

Abstract
A water cooler and dispenser employs a ceramic crock containing a thermoelectric unit and an upwardly directed chilling probe extending into a chilling tank. The chilling probe is in heat-conducting relation to a heat sink, underneath which is a circulating fan. A circulating base is made up of a series of support fins arranged in a radial fashion in the bottom of the crock having a specialized arrangement of inlet and outlet ports. The air is circulated upwardly across the heat sink then circulated downwardly and expelled from the crock. In a conventional manner, water is drawn from the lower end of the chilling tank through a spigot extending to the exterior of the crock.

2. In water cooling and dispensing apparatus having an insulated chilling tank, a thermoelectric unit and heat sink disposed beneath said chilling tank, and a fan unit disposed beneath said heat sink, the improvement comprising:
a generally circular air-circulating base disposed beneath said heat sink, said base comprising a first plate, at least one inlet port through which said outside air is drawn upwardly and across said heat sink by operation of said fan unit, thereby removing heat from said heat sink, at least one outlet port displaced 90 degrees from said inlet port through which said air is expelled from said apparatus by operation of said fan unit, first and second dividing walls extending upwardly from said plate and separating said inlet and said outlet ports, each of said walls defining one of said outlet ports, and a plurality of fins extending upwardly from said plate and spaced circumferentially across each of said inlet and said outlet ports, said fins defining a plurality of air-circulating passageways. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10)
