[0002]

2. Description of the Related Art In a cup-type beverage vending machine in which a beverage is poured into a cup and sold, regular coffee, instant coffee powder, instant cocoa powder, instant black tea powder and the like extracted from coffee bean powder are generally dissolved in hot water. Instant drinks, syrup drinks such as cola and cider, fruit juice drinks, lactic acid drinks, and the like are sold.
Fruit juice drinks and lactic acid drinks are produced by diluting a concentrated stock solution with drinking water. The disposable concentrated stock solution tank is stored and used in a refrigerator installed in a cup-type beverage vending machine. In a conventional cup-type beverage vending machine, no partition plate is provided in a refrigerator room for storing a concentrated undiluted solution.

[0003]

When selling a plurality of kinds of fruit juice drinks, lactic acid drinks and the like, a plurality of kinds of concentrated stock solution tanks are stored in a refrigerator. The appropriate storage temperature varies depending on the type of concentrated stock solution. However, no partition plate was provided in the refrigerator room of the conventional refrigerator, and the temperature in the refrigerator room was almost constant in any part of the refrigerator room, so that the storage temperature could be finely controlled according to the type of the concentrated stock solution. Did not.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a refrigerator of a cup-type vending machine that can more precisely control the storage temperature of a concentrated stock solution than in the past.

[0004]

In order to solve the above-mentioned problems, according to the present invention, a first compartment having a ventilation hole and a guide hole and directly connecting a storage room to a cold air outlet and a cold air outlet are provided. A fixed partition plate that is divided into a second section that is not directly connected, and a movable partition plate that has a ventilation hole and a locking claw and is disposed adjacent to the fixed partition plate. Provided is a refrigerator for a vending machine, wherein a plurality of locking portions that engage with locking claws of a movable partition plate are formed. In the refrigerator of the vending machine according to the present invention, the movable partition plate is locked to the fixed partition plate by engaging the locking claw of the movable partition plate with the locking portion of the guide hole of the fixed partition plate. The guide hole is formed with a plurality of locking parts. By changing the combination of the locking part of the guide hole and the locking claw, the movable partition plate is moved relative to the fixed partition plate to move the movable partition. The degree of overlap between the ventilation hole of the plate and the ventilation hole of the fixed partition plate can be changed, and thus the temperature difference between the first compartment and the second compartment of the refrigerator compartment can be finely managed. If the proper storage temperature of the plurality of concentrated stock solution tanks to be stored in the refrigerator is substantially the same, the degree of overlap between the ventilation hole of the movable partition plate and the ventilation hole of the fixed partition plate is set to 100% to make the temperature in the compartment uniform. If the proper storage temperature of one group of concentrated stock solution tanks and the other group of concentrated stock solution tanks are different, if the difference between them is large, the ventilation hole of the movable partition plate and the ventilation hole of the fixed partition plate overlap. The temperature difference between the first section and the second section is increased by setting the degree of the air gap to 0%. When the difference between the two sections is relatively small, the degree of overlap between the ventilation hole of the movable partition plate and the ventilation hole of the fixed partition plate is determined by several degrees. 10
% To reduce the temperature difference between the first section and the second section, the storage temperature of the concentrated undiluted solution can be more finely controlled than in the conventional case.
