Claims (1)

[Claims for Utility Model Registration] 1. A water supply tank 20 that stores water, an upper ice-making water tank 9 that is supplied with water from the lower water supply tank 20 and stores it, and uses the water in the water supply tank 20 as the ice-making water. Water supply pump device 2 that supplies water to tank 9
1, an ice making section 8 that makes ice from the water supplied from the ice making water tank 9, an ice storage 10 that stores the ice grains made in the ice making section 8, and a drainage water that is in fluid communication with the bottom of the ice storage 10. The tank 36 is in fluid communication with the ice-making water tank 9 and the water supply tank 20 to transfer excess water from the ice-making water tank 9 to the water supply tank 2.
A water storage type ice making device comprising pipes 4 and 24 that are introduced into the water. 2. A first water level detection device 23 provided in the water supply tank 20 to detect a predetermined lower limit water level of the water in the water supply tank 20; and a first water level detection device 23 provided in the drain tank 36 to detect a predetermined lower limit water level of the water in the drain tank 36. A second water level detection device 43 that detects the upper limit water level is connected to the first and second water level detection devices 23, 43, and stops the operation of the ice making device when at least one detects the lower limit water level or the upper limit water level. The water storage type ice making device according to claim 1, further comprising control devices X, _X11 , and _X12 . 3. When a predetermined amount of ice grains 8a in the ice storage 10 is detected, the ice making devices X, X ₁₁ , and X are opened.
an ice storage detection switch Th ₁ that stops the operation of the water level detector ₁₂ ; and an ice storage detection switch Th 1 that is connected to the control devices X, X _{11 and} The water storage type ice making device according to claim 2, further comprising an alarm device L that issues an alarm. 4. The water storage type ice making device according to claim 2 or 3, wherein the drainage tank 36 has a capacity capable of accommodating at least the entire amount of water generated from the predetermined amount of ice grains 8a in the ice storage 10.
