Cold water can be made and supplied in a short time.

  That is, conventionally, when making cold water, normal temperature water is poured into a pipe arranged so as to pass through the bottom of the ice storage part, and cold water cooled with ice while normal temperature water passes through the pipe, the structure is It is complicated and expensive. Furthermore, in order to cool normal temperature water to near 0 degreeC, it must pass through piping for a long time, and it will take time to supply cold water. Furthermore, it is possible to cool to near 0 ° C by storing normal temperature water in the pipe, but there is a limit to the amount of water that can be cooled depending on the length of the pipe arranged in the ice storage section, and the cold drink continues.

  Further, in the ice making machine 12, by rotating the stirring unit 53 together with the auger during normal temperature water supply or every time after water supply, a part of the ice at the water supply point melts due to direct contact with the normal temperature water. In addition, the ice distribution is made uniform, the cooling capacity during the next cold water production operation is maintained, and ice is replenished by rotating the auger.

Here, FIG. 4 shows a result of testing the cold water capacity in a state where the stirring unit 53 of the ice making machine 12 is rotated. The test method is as follows: the temperature of the normal temperature water to be supplied is 23.4 ° C, the target water supply amount for each normal temperature water is 120 cm ³ , the water supply interval is 40 seconds, and one point is concentrated directly below the water supply port 61. The temperature of the cold water flowing out from the cold water outlet 62 and the amount of water were measured 10 times by 15 seconds after the start.

  As shown in FIG. 4, in the state where the stirring unit 53 is rotating, the temperature and the amount of cold water flowing out from the cold water outlet 62 were stable in all ten tests.

  Further, FIG. 5 (a) shows the result of testing the cold water capacity in a state where the rotation of the stirring unit 53 of the ice making machine 12 is stopped. The test method is as described above.

  As shown in FIG. 5 (a), it was confirmed that the temperature of the cold water increases as the number of times of water supply increases in a state where the stirring unit 53 is not rotating. This is because a part of the ice at the water supply point melts due to direct contact with normal temperature water and a hole is formed in the ice layer, so that the cooling capacity is lowered. In addition, since the water temperature rise was confirmed by the 8th time, the test after the 9th time was stopped.

  Further, in FIG. 5 (b), after testing the cold water capacity in a state where the rotation of the stirring unit 53 of the ice making machine 12 is stopped, the result of the test performed once after the stirring unit 53 is rotated for 0.5 seconds. Show. The test method is as described above.

  As a result, the temperature of cold water was lowered. This is due to the ice distribution becoming uniform due to the elimination of the ice holes at the water supply site due to the stirring of the ice.

  In addition, the amount of cold water extracted from the ice making machine 12 is increased by the amount of cold water melted by contact with room temperature water in addition to the amount of water supplied at room temperature. Therefore, in order to supply a predetermined amount of cold water to the cup at a time in a cup-type beverage vending machine, the amount of cold water taken out from the ice making machine 12 in consideration of the amount of cold water that melts the ice by contact with room temperature water. A smaller amount of room temperature water is supplied by controlling the water supply pump 29 of the water supply unit 63. Thereby, a predetermined amount of cold water can be stably supplied to the cup, and the strength of the beverage can be kept constant.

  Further, when an ice-free cold drink is selected by a cup-type beverage vending machine, ice is not taken out, but only cold water is taken out and supplied into a cup arranged on the vent stage 15.

  In addition, the water supply to the ice in the ice storage part 28 of the ice making machine 12 may be a single point concentrated water supply directly from the water supply port 61 or may be distributed and supplied from a water supply port 61 to a wide range.

  Further, in order to improve the efficiency of taking out cold water from the ice storage unit 28 of the ice making machine 12, the bottom shape of the ice storage unit 28 is inclined downward toward the cold water outlet 62, or the cold water outlet 62 A continuous groove may be provided, or the vicinity of the cold water outlet 62 may be recessed.
