Further, the raw material container 2 is replenished with raw materials by an operator who makes rounds at appropriate times.

[Problem to be solved by the invention]

By the way, in conventional beverage vending machines, when powdered raw materials are put into the raw material container 2, some of the raw materials fly up and fall to the outside of the raw material container, which makes the inside of the machine dirty and presents an unfavorable condition in terms of hygiene management. Moreover, there was a drawback that it required a great deal of effort to clean up the scattered raw materials.

An object of the present invention is to provide a cup-type beverage vending machine that uses powdered raw materials and whose interior is kept clean and sanitary, and which can be easily cleaned.

[Means to solve the problem]

In order to achieve the above object, according to the present invention, a raw material container containing powdery raw materials and a hot water tank are provided in the main body case, and raw materials and hot water carried out in response to a sales signal are stirred and mixed in a mixing bowl. In a cup-type beverage vending machine that prepares a beverage, pours the beverage into a cup, and sells the beverage, an exhaust fan is installed inside the main body case, and the suction port of the exhaust fan is connected to the raw material input port of the raw material container. The air outlet shall be located nearby and open toward the outside of the machine.

[Effect]

The raw materials that fly up when the raw materials are input are collected and sucked into a suction port that opens near the raw material input port by an exhaust fan, and are discharged to the outside of the machine. Therefore, the inside of the machine is prevented from being contaminated by the floating raw materials, and cleaning becomes easy.
