FIG. 5 is a water circuit diagram of the cup type vending machine. The cup-type vending machine 1 opens and closes a valve to supply and stop drinking water supplied from the tap water, and the water inlet solenoid valve 9 opens the water inlet solenoid valve 9 to supply the drinking water supplied from the tap water to a predetermined amount. A water reservoir tank 10 that retains and retains the water level, a water supply pump 61 that pumps drinking water stored in the water reservoir tank 10 to each device, and a drinking water solenoid valve that opens a valve when potable water is pumped to the hot water tank 50 56.

JP-A-8-315244 (FIG. 2)

  However, the tap water (drinking water) supplied to the cup type vending machine 1 contains a large amount of air. Further, when drinking water is supplied to the water stored in the water reservoir tank 10, air is blown into the drinking water due to the impact, and a large amount of air is contained. When air contained in drinking water in a large amount in the water supply pipe connected from the water reservoir tank 10 to the water supply pump 61 becomes bubbles, the water supply pump 61 sucks the air bubbles and the water supply pump 61 is in an idle state. Thus, it becomes impossible to supply water to the hot water tank 50 and the carbonator 65, and further, there is a possibility that the service life of the water supply pump 61 is shortened. Also, when drinking water containing bubbles is supplied to the auger type ice making machine 20, the icing on the inner wall of the ice making cylinder is not transported upward and remains in the ice making cylinder, resulting in a supercooled state, abnormal ice quality, and abnormal ice making. There is a risk of overloading the auger drive motor due to the generation of sound and the increase in rotational resistance of the auger.

  In view of the above circumstances, the present invention provides a water circuit for a beverage cooking apparatus that can prevent problems such as idling of a water supply pump, abnormal ice quality, abnormal ice making, overload of an auger drive motor, and the like. With the goal.

A bubble removing means for destroying and extinguishing bubbles generated in the drinking water is provided in a connection portion of the first water supply pipe and / or the second water supply pipe of the water reservoir tank.

  The water circuit of the beverage cooking device according to claim 2 of the present invention is the water circuit according to claim 1, wherein the bubble removing means is formed in an edge shape with a sharpened tip that contacts the bubble. It is characterized by destroying and extinguishing the surface tension resistance by low activation.

And a hot water tank that heats and stores drinking water supplied from a second water supply pipe connected to the water reservoir tank to a predetermined temperature and stores the beverage, and a beverage cooking apparatus that cooks a beverage The bubble removing means for destroying and extinguishing bubbles generated in the drinking water is provided at the connecting portion of the first water supply pipe and / or the second water supply pipe of the water reservoir tank, and the bubble removing means The tip part to be contacted is formed in the shape of a sharp edge, and the surface tension resistance of the bubbles is lowered and destroyed to be extinguished, so that the drinking water in the first water supply pipe and / or the second water supply pipe A large amount of air bubbles Even so, the tip of the bubble removing means that is shaped like a sharp edge is activated by deactivating and destroying the surface tension resistance of the bubbles floating in the drinking water. There is no idle rotation caused by sucking bubbles in the pump, and the service life is not affected. In addition, since drinking water containing bubbles is no longer supplied to the ice making machine, the icing on the inner wall of the ice making cylinder will not be transported upward and will remain in the ice making cylinder and become supercooled, resulting in abnormal ice quality and abnormal ice making. The overload of the auger drive motor due to the generation of sound and the increase in the rotation resistance of the auger can be prevented. This makes it possible to provide a water circuit for a beverage cooking device that can prevent problems such as idling of the water supply pump, abnormal ice quality, abnormal ice making noise, overload of the auger drive motor, and the like.
