Agitator for a post-mix beverage dispenser

Claim 2

In a post-mix beverage dispenser including a supply of flavor concentrate, a carbonator for making carbonated water, a manually refillable water reservoir for supplying water to said carbonator, means for refrigerating water in said water reservoir and means for mixing said flavor concentrate with carbonated water supplied by said carbonator, the improvement comprising: an agitator assembly including a rotary agitator disc within the water of said water reservoir, said disc having continuous uninterrupted smooth planar surfaces on both first and second sides thereof with apertures vertically formed therein permitting the flow of said water therethrough, to thereby increase the amount of water agitation and cooling achieved compared to a similar shaped disc without said apertures.

Claim 3

The dispenser of claim 1, wherein said increased water agitation and cooling occurs at a plurality of water levels within said manually refillable water reservoir, thereby preventing splashing of said water at each of said plurality of water levels and particularly at a water level substantially even with said disc.

Claim 4

The dispenser of claim 1, wherein said disc increases said water agitation and cooling without splashing above a surface level of said water, thereby reducing noise and providing a clean dispenser environment.

Claim 5

The dispenser of claim 1, wherein said disc further prevents splashing above a surface level of said water, including a water level substantially even with said disc.

Claim 6

In a post-mix beverage dispenser including a supply of flavor concentrate, a carbonator for making carbonated water, a manually refillable water reservoir for supplying water to said carbonator, means for refrigerating water in said water reservoir and means for mixing said flavor concentrate with carbonated water supplied by said carbonator, the improvement comprising: an agitator assembly including a rotary agitator disc within the water of said water reservoir, said disc having continuous uninterrupted smooth planar surfaces on both first and second sides thereof with apertures vertically formed therein permitting the flow of water therethrough upon actuation of said disc, to thereby prevent splashing of water by said disc regardless of a water level within said water reservoir.

Claim 7

In a post-mix beverage dispenser including a supply of flavor concentrate, a carbonator for making carbonated water, a manually refillable water reservoir for supplying water to said carbonator, means for refrigerating water in said water reservoir and means for mixing said flavor concentrate with carbonated water supplied by said carbonator, the improvement comprising: an agitator assembly including a rotary agitator disc within the water of said water reservoir, said disc having continuous uninterrupted smooth planar surfaces on both first and second sides thereof with apertures vertically formed therein permitting the flow of water therethrough upon actuation of said disc, to thereby prevent splashing of water by said disc regardless of a water level within said water reservoir.

Claim 8

The dispenser of claim 5, wherein said agitator assembly increases the amount of water agitation and cooling achieved compared to a similar shaped disc without said apertures.
