Energy saving baffle for water cooler
A water cooler assembly and/or liquid dispensing apparatus and method for using same, including an energy-saving baffle, which may take the form of a conventional or bottom load water cooler. Additionally, various other, alternative features may be included, such as: a door stop mechanism; an adjustable drip tray assembly; a leak stop mechanism; an adjustable bottle interface accommodating dimensional variations in water bottles; an instaboil feature; and various programmable dispensing and visual display modes.
1. A liquid dispensing apparatus, comprising:
cold and hot tanks in liquid communication therebetween and with a dispensing faucet, the cold tank housing a baffle in liquid communication with a tube communicating between the cold and hot tanks, the baffle separating two or more regions of liquid in the cold tank having differing temperatures and the baffle tube housing a ball with a specific density less than the specific density of the liquid, whereby the ball normally floats upward within the baffle tube to partially seal against an upper retaining member within the baffle tube and thereby restrict liquid circulation between the hot and cold tanks; and wherein the upper retaining member includes one more openings facilitating the partial seal of the ball against the upper retaining member, to thereby partially relieve pressure from liquid within the hot tank.
2. The liquid dispensing apparatus of claim 1 , wherein the hot tank is located below the cold tank, and following liquid discharge from the hot tank, the ball is pushed downwardly within the baffle tube by liquid flowing from the cold tank to replenish the hot tank.
3. The liquid dispensing apparatus of claim 1 , wherein the baffle includes upper and lower portions.
