The beverage control hole 30 is in the form shown in Fig. 6 in the circumferential direction of the beverage control disc 23b, while the lower side thereof is opened to the same or similar diameter as the corresponding beverage outlets 33a and 33b, while facing upward. It is opened to have a gradually smaller diameter, thereby enabling control of the flow rate during discharge of the mixed water.

That is, the plurality of beverage control holes 30 formed in the beverage control disc 23b of the pivot shaft 23 are each designed to have a diameter of the lower light bar, and the lower diameter of the beverage control hole 30 is Designed identically or similarly to the corresponding beverage outlets 33a and 33b of the beverage relay member 31 and gradually increasing in diameter toward the upper side of the beverage control hole 30 (preferably the corresponding beverage outlet 33a). Half diameter of (33b)).

In addition, the rear cover member 37 is provided at the rear of the beverage relay member 31 to prevent the beverage relay member 31 from being separated from the valve body 11, and the rear cover member 37. Fixing protrusions 37a are formed at both sides of the fixing protrusions 37a and are coupled to the fixing grooves 11b formed in the valve body 11.

On the other hand, both sides of the valve body 11, the first and second to separately enter the beverage (for example, cold water and purified water or cold water and hot water) to be separately supplied from the beverage supply device through a corresponding water supply hose (not shown) Beverage supply ports 40a and 40b are formed. In addition, the first and second beverage supply ports (40a, 40b) for the check valve portion (41a) for preventing the backflow of the beverage flowing from one of the beverage supply port through the other beverage supply port side 41b) is correspondingly mounted.

The check valve portions 41a and 41b are coupled to the corresponding drink supply ports 40a and 40b, respectively, and a hose connection member 42 having a hose connector 42a to which a water supply hose (not shown) for supplying a drink is coupled. And dimensions corresponding to the inner diameter of the third O-ring 43 mounted on the inner surface of the hose connecting member 42 to prevent leakage, and the hose connector 42a of the hose connecting member 42. The rear opening and closing of the beverage opening and closing plate 44 having a coupling projection (44a), the front is formed with a coupling projection receiving groove (45a) for receiving the coupling projection (44a) of the beverage opening and closing plate (44) While the coupling shaft 45b of a predetermined length is formed, a beverage opening / closing plate driving member 45 having a plurality of beverage passing holes 45c (see FIGS. 7A and 7B) for the passage of a beverage around the beverage opening and closing plate driving member An elastic spring 46 coupled to the rear of the 45 and the coupling shaft formed in the rear of the beverage opening and closing disc drive unit 45 ( 45b) is provided with a spring fixing plate 46 to prevent separation of the elastic spring (46).

Therefore, the hose outlet (42a) of each hose connecting member 42 of the check valve portion (41a, 41b) in the state that the beverage discharge valve according to the present invention having the above configuration is made in the form shown in Figure 3 The water supply hoses (eg, cold water supply hoses and purified water supply hoses or cold water supply hoses and hot water supply hoses) that are addressed from the drink supply device are correspondingly connected.

In this state, when the discharge water selection handle 20 is set to the intermediate position, the beverage control hole 30 of the beverage control disc 23b of the pivot shaft 23 is the first and second of the beverage relay member 31. The second beverage outlets 33a and 33b are matched in the form shown in FIG. 8A.

On the other hand, when the discharge water selection handle 20 is rotated to the left, for example, the pivot shaft 23 connected to the discharge water selection handle 20 is also rotated to the left to drink the beverage of the beverage control disc 23b. The control hole 30 is completely matched with the corresponding beverage outlet (eg 33b) of the beverage relay member 31 (see FIG. 8B).

When the beverage dispensing operation lever 14 is operated in this state, the hose of the check valve part (eg 42a) corresponding to the beverage inlet 32b communicated with the beverage outlet 33b of the beverage relay member 31. Drinking water is introduced from the connecting member 42, the force is introduced into the beverage opening and closing plate 43, the beverage opening and closing plate driving portion 44 coupled to the beverage opening and closing disc 43 is accordingly The elastic force of the elastic spring 45 is pushed backwards.

Therefore, the second beverage inlet of the beverage relay member 31 through the second beverage supply port 40b of the valve body 11 has passed through the check valve portion 42a of the hose connecting member 42. After being introduced into the 32b, the water is supplied through the beverage control hole 30 from the corresponding beverage outlet 33b.

The beverage passing through the beverage control hole 30 is the discharge opening and closing member 29 to open the beverage discharge port 12 when the shaft 26 is raised by the operation of the beverage discharge operation lever (14). As a result, the selected beverage (for example, cold water) is discharged through the beverage discharge port 12.

On the contrary, when the discharge water selection handle 20 is rotated in the right direction, the rotating shaft 23 is also rotated in the right direction based on the operation described with reference to FIG. 8B to drink the beverage of the beverage control disc 23b. The control hole 30 is completely matched with the corresponding beverage outlet (eg 33a) of the beverage relay member 31 (see FIG. 8C).

When the beverage dispensing operation lever 14 is operated in that state, the beverage (eg, purified water) selected according to the operation of FIG. 8B is discharged through the beverage dispensing outlet 12 of the valve body 11.

When the beverage discharge operation lever 14 is operated in the state shown in FIG. 8A, the mixed water of cold water and purified water (or cold water and hot water when cold water and hot water are supplied) is the beverage of the valve body 11. It discharges from the discharge port 12.

On the other hand, according to the present invention it is possible to appropriately adjust the mixing amount of the cold water and purified water (or cold water and hot water) according to the rotation amount of the discharge water selection handle 20 (see Fig. 8d).

In addition, the present invention is not limited to the above examples, and various changes and modifications can be made within the scope not departing from the technical gist and point of the invention.

As described above, according to the beverage dispensing valve according to the present invention, a plurality of types of beverages are supplied to a single valve body and optionally any one beverage is discharged or the plurality of beverages are mixed at a desired ratio. It can be discharged from.
