Description

  The present invention relates to a cup-type vending machine provided with a water reservoir for storing water supplied from water supply.

  A cup-type vending machine of the in-cup mixing type for selling cold beverages and hot beverages of this kind is provided with a water reservoir for storing water supplied from a water supply in the vending machine main body, and the water reservoir is connected to the water reservoir via a pipe. An auger-type ice maker that is connected to a water reservoir and water is supplied from a water reservoir, a hot water storage tank that is supplied with water from the water reservoir via a water pump, and the like. The water reservoir is used for selling cold beverages. Is discharged directly into the cup via a water pump and the ice pieces stored in the auger-type ice machine are supplied into the cup. When selling hot beverages, the hot water storage tank heats it to the desired temperature The hot water is discharged into the cup or the coffee brewer. The water stored in the water reservoir is an environment in which residual chlorine (bactericidal effect) decreases over time and bacteria multiply, and the water in the water reservoir flows, particularly when the interval between drink sales becomes longer. It is still water and stays in the water reservoir, so that it becomes an environment where various germs grow. For this reason, an electromagnetic valve is provided in a pipe connecting the water reservoir and the auger-type ice maker as a means for draining water stored in the water reservoir, and the water stored in the water reservoir is automatically replaced. I have. By the way, when the water stored in the water reservoir is automatically replaced, the water stored in the water reservoir is drained to a drainage container (bucket) installed in the main body of the vending machine. The capacity of the drainage container installed in the vending machine main body is limited, and maintenance of the drainage container is performed by a routeman. Therefore, when the water stored in the water reservoir is frequently replaced, it is necessary to increase the number of routeman tours (to shorten the tour period). However, when the number of times of the routeman's patrol is increased only for the maintenance work of the drainage container, there is a problem that the labor of the routeman increases and the running cost increases. Therefore, as a measure for preventing the growth of various bacteria without replacing the water stored in the water reservoir, there is known a method in which a germicidal lamp that emits ultraviolet light is inserted into the water reservoir and sterilization is performed by irradiation with ultraviolet light ( For example, Patent Document 1).

For example, when the storage capacity of the water reservoir 1 is “1 L” and the flow rate of the water pump PMP 0 is Ｌ L per minute, the water pump PMP 0 The driving time of the ultraviolet light source (ultraviolet LED) is set to at least 2 minutes. As described above, the water pump PMP0 is driven to circulate the water stored in the water reservoir 1 and the ultraviolet light source (ultraviolet LED) is driven at the same time as the water pump PMP0, so that the water in the circulation is irradiated with ultraviolet rays. In addition, by flowing the water stored in the water reservoir 1, it is possible to prevent the propagation of various germs that easily proliferate in the still water state. In the circulating water circuit 101 according to the first embodiment, even when the beverage sales control program is executed during the activation of the ultraviolet sterilization control program, the ultraviolet sterilization control and the beverage sales control can be performed in parallel. .

With this, the water stored in the water reservoir 1 is circulated by the water pumps (PMP0, PMP1, PMP2) and the circulating water circuits (101, 10). A, 101B), the water in circulation can be sterilized by irradiating ultraviolet rays with ultraviolet irradiation means (ultraviolet irradiation device 110) disposed in the water reservoir 1, and furthermore, the water stored in the water reservoir 1 is brought into a still water state. Since the water can be flowed without any problem, it is possible to suppress the growth of various bacteria.

  In the cup-type vending machine according to each of the above-described embodiments, the cup-type vending machine of the in-cup mixing type in which the beverage is stirred in the cup C has been described, but a mixing bowl (not shown) is used. The present invention can also be applied to a method in which a desired beverage is prepared by stirring and mixing powdered raw materials such as coffee, cream, sugar and the like with hot water supplied from a hot water storage tank via a hot water supply valve. Further, in the cup-type vending machine according to the embodiment, the water stored in the water reservoir 1 is supplied to the cup C by the water pump PMP1 in order to prepare the cold beverage. Is adjusted by the hot water stored in the hot water storage tank 3 (the time for driving the hot water supply valves V2 and V3 is adjusted to be shorter than that for adjusting the hot beverage with a small amount of hot water, and then the ice is supplied from the auger type ice making machine 2). It is also possible to supply a piece to the cup C to prepare a cold beverage). Therefore, the present invention is not limited to the cup-type vending machine of the embodiment.
