DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application This invention relates to a beverage dispenser, and more particularly to a beverage dispenser having a function of supplying ice to a cup.

b. Prior Art Figures 2 to 6 show a carbonated beverage dispenser already commercially available by the applicant as an example of a conventional beverage dispenser.As shown in the process diagram of Figure 2, a carbon dioxide gas cylinder 1 The carbon dioxide gas inside is supplied to a syrup tank 3 and a carbonator 4 via a regulator 2. The carbonated water liquid level within the carbonator 4 is controlled by a liquid level detection device 29 provided within the carbonator 4 . When the carbonated water level is low, a signal from the liquid level detection device 29 drives the pressure pump 30, and pressurized water is supplied into the carbonator 4. The mist water in the carbonator 4 is brought into gas-liquid contact with carbon dioxide gas, absorbs carbon dioxide gas, and becomes carbonated water. Both the carbonated water and the syrup are supplied to the cooling device 7 by the gas pressure of carbon dioxide gas in the upper space of the carbonator 4 and syrup tank 3. Here, the carbonated water and syrup are cooled with ice in a second ice storage 17, which will be described later. The cooled carbonated water and syrup are dispensed from the beverage dispensing valve 10 by pressing the lever 28 into a cup 26 which has previously been filled with ice.

In FIG. 6, which is a cross-sectional view of a conventional carbonated beverage dispenser, an ice-making device 12 for producing ice is provided within 11. A first ice storage 13 is provided above the ice making device 12 in which ice produced by the ice making device 12 is stored. An ice shooter 14 extends downward from one side of the ice storage 13, and an ice shooter 15 extends downward from the other side. The ice shooter 15 is connected to a second ice storage 17 via a well-known ice discharge mechanism 16. When the ice discharge mechanism 16 operates, the first ice storage 1
3 falls into the second ice storage 17.

A well-known plate-shaped cooling device 7 is attached to the lower part of the second ice storage 17. The cooling device 7 is connected to its front end in FIG. 6 with an inlet hose 18 through which carbonated water from the carbonator 4 flows and four inlet hoses 18' through which different syrups flow. The carbonated water and each syrup that entered from each inflow hose 18, 18' make a U-turn inside the cooling device 7, and return to the discharge hose 19 provided at the end of the cooling device 7 from which the carbonated water is drained, and each syrup. It is discharged through a discharge hose (not shown).

The discharge hose 19 for carbonated water and the discharge hoses for each syrup are covered with a heat insulating material 22 provided around the ice shooter 15 and connected to each beverage outlet valve 10 provided on the front of the case 11. ing. Therefore, when syrup and carbonated water pass through each discharge hose 19, the temperature of the syrup and carbonated water can be prevented from rising. Note that the reference numeral 23 in FIG. 6 indicates an ice storage detection device, and this device 23 sends a signal to the ice discharge mechanism 16 when the ice in the second ice storage 17 exceeds a predetermined amount, and from the ice storage 13 to the second ice storage 17
The supply of ice to the area has been cut off.

An ice shooter 14 extending in front of the first ice storage 13 communicates with an ice discharge port 25 provided at the front of the case 11 via a well-known ice discharge mechanism 24 . A cup 26 is disposed below the ice discharge port 25, and by pushing the cup 26 backward, an ice discharge switch 27 located at the rear of the cup 26 is actuated, and the ice discharge mechanism 24 is operated. Inside the cup 26 is a first ice storage 13.
The ice inside is added.

Next, a process in which ice produced by the ice making device 12 is stored in the first ice storage 13 and the second ice storage 17 will be described using the circuit diagram in FIG. 3. Normally, the changeover switch 31 is open, so the ice discharge mechanism 16 is not energized, and the ice in the first ice storage 13 is not supplied to the second ice storage 17. The ice produced by the operation of the ice making device 12 is
supplied into the first ice storage 13, the first ice storage 1
3 becomes full of water, the ice storage detection device 32 attached to the first ice storage 13 operates and the ice making device 1
2 circuit is cut off, and its production is stopped.

For example, if carbonated drinks are not sold at night,
By closing the changeover switch 31, ice produced by the ice making device 12 is supplied to and stored in the second ice storage 17. By closing the changeover switch 31, the ice discharge mechanism 16 is operated via the ice storage detection device 23, and the ice in the first ice storage 13 is stored in the second ice storage 17 through the ice shooter 15. . When the ice in the second ice storage 17 reaches a predetermined amount, the ice storage detection device 23 is activated, its contacts are opened, and the power supply to the ice discharge mechanism 16 is cut off. Then, the ice discharge mechanism 16 stops the ice in the first ice storage 13 from falling into the second ice storage 17 and being supplied. Furthermore, when the ice making device 12 continues to operate and ice is produced, the first ice storage 13 becomes full of water, at which point the ice storage detection device 32 is activated and its contacts are opened, and the ice making device 12 Electricity is cut off and ice production is stopped.

Ice and carbonated water produced as described above;
Syrup is sold as a carbonated drink in the following manner. First, the operator places the cup 26 facing the ice discharge port 25 as shown in FIG. 4, pushes the cup 26 toward the rear of the case 11, and operates the ice discharge switch 27. The operation of the ice discharge switch 27 activates the ice discharge mechanism 24, and the ice in the first ice storage 13 is thrown into the cup 26 from the ice discharge port 25 through the ice shutter 14. next,
Beverage dispensing valve 1 for dispensing the type of syrup to be sold from a cup 26 containing ice as shown in FIG.
By pressing the lever 28 through the cup 26, carbonated water and syrup are injected into the cup 26, creating a cold carbonated beverage.

c Problems to be Solved by the Invention As described above, in the conventional carbonated beverage dispenser, the ice stored in the second ice storage 17 reaches each of the inlet hoses 18, 18' and the outlet hose 19, The ice that has reached the inlet hoses 18, 18' and the outlet hose 19 is
8' and the discharge hose 19, causing an arching phenomenon, or the inflow hoses 18, 19
There was a problem in that the syrup and carbonated water in the exhaust hose 8' and the discharge hose 19 would freeze.
On the other hand, the ice stored on the cooling device 7 is syrup,
The lower part of the stored ice is melted by heat exchange with the carbonated water, but the ice presses the surface of the cooling device 7 to the extent that arching occurs between the inlet hoses 18, 18' and the outlet hose 19. There was also a problem in that ice was not replenished near the surface of the cooling device 7 where it had melted, and the cooling efficiency of the syrup and carbonated water by the cooling device 7 was reduced.
