Multi-flavor valve
First Claim
1. A multi-flavor valve capable of dispensing at least three flavors of beverages, comprising:
- a single-piece injection-molded valve body having at least three syrup flow paths and a water flow path;
at least three syrup flow path solenoids for respectively opening and closing the at least three syrup flow paths, and one water flow path solenoid for opening and closing the water flow path, the three syrup flow path solenoids positioned in the corresponding syrup flow paths, and the water flow path solenoid positioned in the water flow path, within the valve body;
at least three beverage flavor switches for selecting any one of the three beverage flavors for dispensation; and
an electronics module electrically connected to the solenoids and to the beverage flavor switches, the electronics module causing one of said syrup flow path solenoids to open the corresponding syrup flow path of the syrup corresponding to a selected flavor switch, and causing the water flow path solenoid to open the water flow path, thereby causing the multi-flavor valve to dispense the selected beverage flavor.

Abstract
A multi-flavor valve capable of dispensing at least three flavors of beverages is provided. The valve includes a single-piece injection-molded valve body having at least three syrup flow paths and a water flow path. The valve also includes at least three syrup flow path solenoids for respectively opening and closing the at least three syrup flow paths, and one water flow path solenoid for opening and closing the water flow path. The three syrup flow path solenoids are positioned in the corresponding syrup flow paths, and the water flow path solenoid is positioned in the water flow path, within the valve body. The valve also has at least three beverage flavor switches for selecting any one of the three beverage flavors for dispensation. The valve further includes an electronics module electrically connected to the solenoids and to the beverage flavor switches, the electronics module causing one of the syrup flow path solenoids to open the corresponding syrup flow path of the syrup corresponding to a selected flavor switch, and causing the water flow path solenoid to open the water flow path, thereby causing the multi-flavor valve to dispense the selected beverage flavor.

2. A method for dispensing a selected beverage flavor from a multi-flavor valve, the multi-flavor valve having a water flow path solenoid and at least three syrup flow path solenoids, the method comprising the steps of:
-
opening the water flow path solenoid;
opening one of the syrup flow path solenoids corresponding to the selected beverage flavor after a predetermined period after the water flow path solenoid has been opened;
closing the opened syrup flow path solenoid after the selected beverage flavor has been dispensed; and
closing the water flow path solenoid after another predetermined period after the syrup flow path solenoid has been closed.

3. A multi-flavor valve capable of dispensing at least three flavors of beverages, comprising:
-
a single-piece injection-molded valve body having at least three syrup flow paths and a water flow path;
an integrated diffuser for diffusing water dispensed from the water flow path; and
an integrated syrup tube, comprising at least three channels corresponding to the at least syrup flow paths, through which channels one of the syrups, corresponding to a selected beverage flavor, is dispensed at a dispensing end of the syrup tube, wherein the surface tension of the syrups at the dispensing end of the syrup tube substantially prevents unselected syrups from dripping out of the corresponding channels during dispensation of the selected beverage flavor, thereby minimizing flavor and color contamination of the dispensed beverage flavor. - View Dependent Claims (4, 5)

10. A valve front cover comprising:
-
a front cover housing; and
a switch membrane comprising a plurality of beverage flavor switches mounted on the front housing cover, wherein one of the plurality of beverage flavors may be simultaneously selected and dispensed by pressing a corresponding beverage flavor switch.
