Abstract

PURPOSE:To sell merchandise at a temperature instructed by a customer by calculating the ratio of mixing hot water and cold water by an operation control unit and mixing the both kinds of water after deciding the time for supplying them. CONSTITUTION:When selected beverage can control the temperature, the temperature of the hot water and the temperature of the cold water are measured by a hot water temperature measuring device 5 and a cold water temperature measuring device 8, and an operation control unit 12 calculates the ratio of mixing the hot water and the cold water so that the temperature of the beverage can be same as the one instructed by a temperature instructing switch 1. According to these amounts of the hot water and the cold water, the time for opening a hot water valve 10 and a cold water valve 10 and set to a hot water timer 3 and a cold water timer 4. Raw materials are carried out by a raw material carry-out motor 11 and the hot water valve 10 and the cold water valve 10 are opened only for the time set to the hot water timer 3 and the cold water timer 4. Then, the beverage is sold after supplying the hot water from a hot water tank 6 and cold water from a cold water tank 9.

1 is a hot water valve for supplying hot water from a hot water tank, 8 is a cold water measuring device for measuring the temperature of a cold water tank, 9 is a cold water tank for supplying cold water, 1o is a cold water amount for supplying cold water, 11 is for carrying out raw materials The raw material discharge motor 12 is an arithmetic and control device that calculates the mixing ratio of the amount of hot water and the amount of cold water and determines the hot water timer and cold water timer values, and the components from the temperature indication switch 1 to the raw material discharge motor 11 are connected.

The operation of the vending machine having the above configuration will be explained with reference to FIG.

First, it is necessary to determine whether the product selection switch 2 has been operated.
l) If it has been operated, it is determined whether the selected beverage is a temperature-adjustable beverage (S2), and if it is a temperature-adjustable beverage, it is determined whether the temperature has been instructed by the temperature instruction switch 1 (S3).
), If the temperature is indicated by the temperature indication switch 1, the hot water temperature and cold water temperature are measured by the hot water temperature measuring device 6 and the cold water temperature measuring device 8 (S4), the measured hot water temperature or cold water temperature is indicated. If the temperature has not been reached as instructed in step S5), the arithmetic and control unit 12 calculates the mixing ratio of the hot water amount and the cold water amount so that the specified temperature is reached, and as a result of the calculation, Hot water valve 7 and cold water valve 1 based on hot water amount and cold water amount
Determine the time to open 0, hot water timer 3 and cold water timer 4.
(S6). When the calculation is completed, the raw material is transported out by the raw material transport motor 11, and the hot water timer 3 and the cold water timer 4
It returns to the hot water valve and standby state only for the time. When the temperature is not adjustable (S2), when the temperature indication switch 1 is not operated (S3), when the temperature has reached the specified temperature (S5)
sells at normal temperature (S8). Product selection switch 2
If is not operated, it returns to the standby state (Sl).

As described above, according to this embodiment, hot water is supplied from the tank 6 based on the temperature information from the hot water temperature measuring device 5 and the cold water temperature measuring device 8 in order to reach the temperature specified by the temperature indicating switch 1. The mixing ratio of the amount of hot water and the amount of cold water supplied by the cold water tank 9 is calculated by the arithmetic and control device 12, and the hot water valve 7 and the cold water valve 10
