Abstract

An ice crusher is attached to an ice dispenser or to a combined ice and beverage dispenser. The ice crusher occupies minimal space in order to fit the dispenser into an existing space on a serving counter or in a beverage dispensing area. The ice crusher may also elevate the ice. In embodiments using this technique, the outlet of the ice from the ice crusher is higher than the ice inlet. As the ice flows from a source of ice, such as an ice bin, the ice is elevated while it is being crushed. The ice then flows from the outlet of the ice crusher down an ice chute or other outlet of the ice crusher, into a cup or container as desired. Other embodiments convey the ice without lifting it, and still other embodiments dispense either crushed or cubed ice, as the consumer may select. In one embodiment the selected crushed ice or cubed ice are both dispensed though the same ice dispensing chute. A retrofit kit may be used to add an ice crusher to an existing ice dispenser, or to an existing combined ice and beverage dispenser.

Claims

1. A combination of a beverage dispenser and an ice crusher, the combination comprising:

a) a beverage dispenser having an ice bin for storing ice cubes and a cold plate, wherein syrup for at least one beverage is routed through tubing in the cold plate;

b) an ice crusher housing having an inlet connected to the ice bin;

c) an ice crusher within the ice crusher housing forming crushed ice from the ice cubes, the ice crusher comprising at least one rotating crusher blade and at least one non-rotating crusher blade within the ice crusher housing, the ice crusher further comprises a wiper removing crushed ice from the rotating crusher blade, the crushed ice being lifted by the rotating crusher blade after the crushed ice is formed and before it contacts the wiper; and

d) a crushed ice outlet from the ice crusher housing; and

wherein the ice crusher and housing are configured and attached to the dispenser such that ice is raised in elevation between a place in the ice crusher housing where the crushed ice is formed and the crushed ice outlet.

2. The combination of claim 1 wherein the ice bin is not refrigerated, ice cubes from the ice bin are fed to the ice crusher by a downward sloping chute and the bottom of the ice crusher housing outlet is at least as high in elevation as the bottom of the ice crusher housing inlet.

3. The combination of claim 1 wherein the ice bin further comprises a cubed ice outlet, wherein a user may dispense crushed ice from the crushed ice outlet or cubed ice from the cubed ice outlet.

4. The combination of claim 3 wherein the crushed ice outlet and the cubed ice outlet both connect to the same dispensing chute.

5. The combination of claim 3 wherein the crushed ice outlet and the cubed ice outlet each connect to different dispensing chutes.

6. The combination of claim 1 further comprising a motor and a drive shaft connected to the motor, wherein the drive shaft has an interface for driving each of the at least one rotating crusher blades.

7. The combination of claim 1 wherein the ice crusher housing outlet is connected to a dispensing chute.

8. The combination of claim 1 wherein the ice crusher housing further comprises a door adjacent to and normally closing the crushed ice outlet that can be opened to allow crushed ice to be dispensed through the crushed ice outlet.

9. The combination of claim 1 wherein the ice crusher housing comprises at least one removable side.

10. The combination of claim 1 further comprising an ice maker having an outlet positioned to deliver ice to the ice bin.

11. The combination of claim 1 wherein the wiper is provided by a part formed on each of the at least one non-rotating crusher blades.

12. The combination of claim 3 comprising one switch for selecting whether cubed ice or crushed ice will be dispensed and a second switch for activating dispensing of the ice.

13. The combination of claim 12 wherein the ice crusher housing further comprises a door adjacent to and normally closing the crushed ice outlet that can be opened to allow crushed ice to be dispensed through the crushed ice outlet.

14. The combination of claim 1 wherein a paddlewheel is located in the ice bin and is used to transfer ice to the ice crusher housing.

15. The combination of claim 3 further comprising at least one mixing and dispensing valve for mixing said syrup and water and dispensing a beverage and wherein cubed ice may pass from the ice bin and into the ice crusher when the user selects to dispense crushed ice and wherein cubed ice may pass from the ice bin through the cubed ice outlet when the user selects to dispense cubed ice.

16. The combination of claim 15 wherein first and second solenoid-activated doors are used to control whether the dispenser will deliver cubed ice or crushed ice, and the second door is downstream of the ice crusher.

17. The combination of claim 16 further comprising a selector for selecting whether the dispenser will deliver cubed ice or crushed ice and wherein when cubed ice is selected on the selector and ice dispensing is activated, the first solenoid-activated door opens the cubed ice outlet and cubed ice is dispensed, and when crushed ice is selected on the selector and ice dispensing is activated, the ice crusher is activated and the second solenoid-activated door is opened, allowing crushed ice from the ice crusher to be dispensed.

18. The combination of claim 1 wherein the ice crusher further comprises a safety guard pivotally mounted so that its bottom can swing away from the ice crusher, allowing crushed ice to pass into a dispensing chute, but the guard can only swing back to a position where it stops to prevent someone from sticking a finger up into the chute and getting it in contact with the ice crusher.

19. The combination of claim 1 wherein the crushed ice outlet is not at the bottom of the housing.
