Introduced in 61, when the water supply (replenishment) reaches the prescribed water level,
Excessive water flows out into the drainage pan 9 through the overflow pipe 76, and if the outflow to the drainage pan 9 is visually confirmed,
Stop the water supply by manually closing the water supply valve 75.

In the water-cooled heat storage system, since the cooling water in the cooling water tank 61 is not used as a beverage, only a small amount of spontaneous evaporation is reduced. Therefore, once replenished, there is no need to constantly supply water. Therefore, a manual water supply system can be used, and the cost can be reduced as compared with the case of automation. Moreover, as for the natural evaporation of the cooling water in the cooling water tank 61, the natural evaporation of the cooling water is automatically introduced by introducing the cold water leaking from the air pipes 84 and 85 into the cooling water tank 61 at the time of supplying the cold water. Can be compensated for, and the labor of supplying cooling water can be reduced.

By the operation of the refrigerator, the cooling water is cooled through the refrigerant coil 73, and ice having a predetermined thickness is accumulated on the surface of the refrigerant coil 73. At the same time, the agitator 71 is rotated to generate a downward water flow in the cooling water, and the cooling water in the cooling water tank 61 is circulated. At this time, by the convex guide portion 64 on the bottom surface of the cooling water tank 61, the agitating water flow by the agitator 71 can be smoothly guided between the upper cooling coil 73 and the cooling coil 74, and the surface of the cooling coil 73 can have a uniform thickness of ice.

The gap between and can be kept constant.

At the time of pouring out the beverage liquid, if a selection button provided on the front surface of the door body is used to perform a hot or cold selection operation together with the type of beverage, the corresponding canister 3 mixes the powdered raw material for beverage with a mixing ball. 4, the hot water or cold water is supplied to the mixing ball 4 through the elbow 19, and the stirring blade body 17 is rotated in the mixing ball 4 to mix and mix the beverage powder raw material with the hot or cold water to obtain the drinking liquid. Is prepared, and the prepared beverage liquid is poured into the cup 22 arranged in the cup station 5 through the beverage pouring outlet 15 and the pouring nozzle 18. At the time of this beverage preparation, the exhaust fan device 6 sucks and exhausts steam and moisture in the mixing ball 4.

The hot water is supplied by flowing the hot water from the upper layer in the hot water tank 41 to the mixing ball 4 through the hot water supply pipe 53 and the elbow 19 by opening the solenoid valve 51. When hot water is directly supplied to the cup station 5, the solenoid valve 52 is opened to allow hot water in the upper layer in the hot water tank 41 to flow out through the hot water supply pipe 54 and the hot water nozzle 25 to supply hot water.

The cold water is supplied by the solenoid valves 79 and 80.
By the combination of the opening with the drinking water, the drinking water is introduced into the cooling coil 74 by the water supply pressure of the drinking water guided to the water supply pipe 45.
The cold water cooled while passing through the cooling coil 74 is cooled by the cold water pipe 82.
And through the elbow 19 to the mixing ball 4. In addition, when the cold water is directly supplied to the cup station 5, the combination of opening of the solenoid valve 79 and the solenoid valve 81 causes the drinking water to be supplied to the water supply pipe 45 under the supply pressure.
Drinking water is passed through the cooling coil 74, and cold water cooled while passing through the cooling coil 74 is supplied through the cold water pipe 83 and the cold water nozzle 26.

At the time of supplying the cold water, when the solenoid valves 80 and 81 are closed, air is introduced from the air pipes 84 and 85 into the cold water pipes 82 and 83 to improve the replacement of the cold water with the air, and Valve 8
The drooping time after drinking liquid or cold water after closing 0, 81 can be shortened. Further, a part of the cold water passing through the cold water pipes 82, 83 leaks from the air pipes 84, 85. By introducing the leaked cold water into the cooling water tank 61, the natural evaporation of the cooling water in the cooling water tank 61 is reduced. Can be automatically supplemented.

A convex guide portion is provided on the bottom surface of the cooling water tank 61.

The cooling water tank 61 can be integrally formed by resin molding including the convex guide portion 64 and the coil holding portion 68, and the number of parts can be reduced and the assembly can be simplified.

Moreover, since the coil holding portion 68 is constituted by the step portion 67 formed at the boundary between the upper side wall portion 65 and the lower side wall portion 66 of the cooling water tank 61, the strength of the side wall portion 63 of the cooling water tank 61 is improved. The capacity can be improved and the capacity of the cooling water tank 61 can be reduced.

Further, by forming the convex guide portion 64 and the coil holding portion 68 in the cooling water tank 61, the capacity of the cooling water tank 61 can be reduced, that is, the cooling water can be reduced and the cooling time of the cooling water can be shortened. The cooling efficiency can be improved.

The reduction of the capacity of the cooling water tank 61 also has an advantageous effect when the cooling water is manually supplied to the cooling water tank 61. That is, when the water supply valve 75 is manually opened to introduce the cooling water into the cooling water tank 61, it is necessary to visually confirm that the surplus flows out to the drainage pan 9 through the overflow pipe 76. If the capacity of 61 is small, the water supply time is shortened accordingly, and the time required for visual confirmation can be shortened.

Further, as shown in FIG. 2, the lower portion of the refrigerant coil 73 is also held by the coil holding portion 68. In this case, the coil holding portion 68 is formed by the fin 101 protruding from the inner wall surface of the cooling water tank 61 (similar to the fin 101 of the second and third embodiments described later), so that the bottom surface of the cooling water tank 61 is formed. The guide function for rectifying and guiding the water flow from the side toward the refrigerant coil 73 and the cooling coil 74 can also be used.

Next, FIG. 3 shows a second embodiment.

The coil holding portion 68 is composed of a plurality of fins 101 integrally formed to project from the inner wall surface of the cooling water tank 61. The plurality of fins 101 project substantially vertically from the inner wall surface of the cooling water tank 61 and are arranged radially around the convex guide portion 64 of the cooling water tank 61. Are formed with groove portions 102 and 103 for engaging and holding the lower portions thereof.

The side wall portion 63 of the cooling water tank 61 is formed to have the same diameter.

Next, FIG. 4 shows a third embodiment.

The coil holding portion 68 is composed of a plurality of fins 101 integrally formed to project from the inner wall surface of the cooling water tank 61. The plurality of fins 101 project substantially vertically from the inner wall surface of the cooling water tank 61 and are arranged radially around the convex guide portion 64 of the cooling water tank 61. Are formed with groove portions 102 and 103 for engaging and holding the lower portions thereof.

Further, the side wall portion 63 of the cooling water tank 61 has a large diameter upper side wall portion 65 formed on the upper side and a small diameter lower side wall portion 66 formed on the lower side, and these upper side wall portion 65 and the lower side wall portion are formed. Since the inclined portion 104 is formed at the boundary with the 66, the capacity of the cooling water tank 61 can be reduced and the water flow along the inner wall surface of the cooling water tank 61 can be made smooth.

The second embodiment shown in FIG. 3 and the third embodiment shown in FIG. 4 have the same effects as the first embodiment, and moreover, the coil holding portion 68.
Is constituted by a plurality of fins 101 that are projected substantially vertically from the inner wall surface of the cooling water tank 61, and rectifies and guides the water flow from the bottom side of the cooling water tank 61 toward the refrigerant coil 73 and the cooling coil 74. Can also be used as a guide function.

Even if the fins for holding the refrigerant coil 73 and the fins for holding the cooling coil 74 are separately configured and these fins are arranged alternately along the inner wall surface of the cooling water tank 61, the same result can be obtained. It produces a working effect.
