The continuous discharge structure 200 is basically the locking groove 202 formed in the rear of the valve body (12; 110) and the holding groove 202 is maintained in a state that the leading end is caught in the discharge operation lever 20; 140 is composed of a locking piece 204 to be maintained in a state that is pushed backward, or a locking piece is formed in the rear of the valve body (12; 110) and the locking groove is formed in the discharge operation lever (20; 140) The structure which becomes is adopted.

On the contrary, according to the present invention, the continuous discharge structure 200 may be changed into various forms, and of course, the discharge operation levers 20 and 140 may be disposed at predetermined positions of the discharge operation levers 20 and 140. It is also conceivable to form a lever front drive prevention jaw to prevent the state is raised to the front, or the formation of the operating knob protruding laterally to facilitate the operation of the locking piece 204.

10A and 10B illustrate a backflow prevention structure formed in consideration of a situation in which a backflow occurs when heterogeneous drinking water is supplied through a single valve body in a beverage discharge valve according to the present invention.

That is, the backflow prevention structure 300 shown in FIGS. 10A and 10B has a relatively small inner diameter and is for example watertightly coupled to the first housing 302 and the first housing 302 to which the room temperature water supply hose is connected. Its interior has a relatively expanded inner diameter, one end of which is composed of a second housing 304 coupled to the water inlet (e.g. 14b in FIG. 1, e.g. 122b in FIG. 6), the first and second housings ( In the coupling position of the 302 and 304, a fixed member 306 having a plurality of water supply zones open and a backflow preventing plate 308 coupled to be able to flow somewhat to the fixing hole 306a formed in the middle of the fixed member 306 are integrated. Is provided in combination.

Therefore, when the non-return structure 300 is employed, the second non-return plate 308 may be reversed by the normal temperature water introduced into the first housing 302 in a state in which normal temperature water is supplied from a beverage supply device. The drinking water is supplied to the corresponding water inlet side through the housing 304.

On the other hand, when a backflow occurs from the water supply port side, a backflow force acts on the backflow prevention plate 308, so that the backflow prevention plate 308 is in close contact with the fixing member 306, thereby preventing backflow.

On the other hand, the present invention is not limited to the above examples, and various changes and modifications are possible, of course.

That is, the structure of the discharge water selection pivot member 40 can be changed to the form shown in FIG. 11, and according to the discharge water selection pivot member indicated by 400 in FIG. 11, the water supply port 14a and 14b may be provided. Inlet grooves 402a and 402b are formed to have an opening ratio that gradually decreases from one side to the other side in order to discharge the obtained cold water and purified water or a mixture thereof.

That is, referring to FIGS. 12A and 12B, when the discharge water selection lever 18 is set to a discharge position of, for example, cold water flowing from the water inlet 14a, the water inlet groove 402a is connected to the water inlet 14a. Matching (i.e., see FIG. 12A) is achieved to discharge the desired cold water.

On the other hand, when the discharge water selection lever 18 is set at, for example, a constant discharge position flowing from the water inlet 14b, the inlet groove 402b is matched to the water inlet 14b (see Fig. 12B). The discharge of purified water is made.

In addition, when the discharge water selection lever 18 is adjusted to overlap the water supply ports 14a and 14b, cold water and purified water are mixed and discharged at a ratio corresponding to the control state.

Therefore, in the structures shown in FIGS. 11, 12A, and 12B, it is possible to more easily discharge the mixed water and selectively discharge cold water or purified water.

13A and 13B are views illustrating another example of the discharge water selection pivot member applied to the beverage discharge valve according to the present invention. The beverage discharge valve shown in the figure is configured to open and close the water inlets 14a and 14b. The discharge water selection rotating member 500 is tapered and removed in an inclined manner so that one side surface 504 is formed to form the water supply shutoff portion 502. According to the rotation operation of the discharge water selection lever 18, the water supply shutoff portion 502 completely seals one side of the water supply ports 14a and 14b, thereby enabling the selective discharge of cold water or purified water, or the cold water. The mixed water of and integer is discharged.

Accordingly, the discharge water selection rotating member 500 shown in FIGS. 13A and 13B can relatively selectively discharge cold water and purified water or discharge mixed water.

6 and 7, although the first and second water supply paths are formed up and down, the first and second water supply paths may be formed in the horizontal direction.

In addition, the continuous discharge structure can be variously changed and modified based on the basic configuration examples shown in Figs. 9A and 9B.

As described above, according to the beverage discharge valve according to the present invention it is possible to selectively discharge the drinking water by forming a plurality of water supply paths in a single valve body, the limitation of the overall design specification when actually applied to the beverage supply device Can be excluded.

In addition, since the continuous discharge structure for continuous discharge is applied to the beverage discharge valve, it is possible to discharge a desired amount of drinking water without continuously operating the discharge operation lever even when continuous discharge of drinking water is required.

Moreover, even when a plurality of water supply paths are designed inside a single valve body, the application of a backflow prevention structure makes it possible to extremely exclude the influence of the occurrence of backflow on other water supply paths.
