Abstract

PURPOSE:To fixedly maintain the quality of discharged ice cubes by detecting that the water level of a reservoir tank is dropped less than a standard level, starting a timer, and when the timer time reaches a regulated time, stopping ice manufacturing operation. CONSTITUTION:A protection device 21 checks an output signal from an upper water level switch 16, and at the time of detecting that the float 14 of the reservoir tank is set up on the standard water level, resets the timer. At the time of detecting the drop of the water level in the step, the timer is started to increase the contents of the timer. Then whether the increased contents of the timer reach the prescribed value corresponding to the regulated time or not is checked. When water feeding capacity is low, the timer value reaches the prescribed value before the switch 16 detects restoration to the standard water level and the operation stop of a compressor 6 in an ice manufacture control part 20 and the motor 7 of an auger 8 is instructed.

Generally, the water level sensor 4 has a float 14 that moves up and down according to the water level in the reservoir tank 1, and the float 14 is at a standard water level. The upper water level switch 16 detects via the operating rod 15 that the float 14 is at a level lower than the standard water level LoJ, "), and the lower water level switch 17 detects via the operating rod 15 that the float 14 is at a lower level than the standard water level LoJ"). When the water level switch 16 detects the float 14, the solenoid valve 19 installed in the water supply pipe 18 is switched to the closed state to supply water to the reservoir tank 1.When the water level drops from the standard level, the solenoid valve 19 is closed. 19 is configured to switch to a water flowing state.When the sewage level switch 17 detects the float 14, the vending machine is switched to a vending state.

Problems to be Solved by the Invention In such a conventional configuration, if the vending machine is installed near the top floor of a building and the water supply capacity is low or there is a water outage, the water level in the cooling cylinder 2 will drop. may occur, resulting in a decrease in ice-making capacity, water quality becoming too hard, or
This is undesirable because a situation may occur in which the sizes of the parts 3 become uneven. If the water level in the cooling cylinder 2 drops further, arching will occur in the cooling cylinder 2, making it impossible to scrape up the water with the auger 8, and the water level will drop to the standard level. There is a problem in that even if the ice-making operation returns to normal, normal ice-making operation cannot be resumed immediately.

Means for Solving the Problems The ice making device of the present invention connects the bottom of the reservoir tank and the bottom of the cooling cylinder to supply water to the cooling cylinder, detects the water level of the reservoir tank with a water level sensor, and detects the water level of the cooling cylinder. The water supply to the reservoir tank is controlled so that the water level is at a standard level, and ice adhering to the inner wall of the cooling cylinder is scraped up by an auger and compressed to make ice. A protection device is provided which starts timing upon detecting that the water level has fallen below a standard level, and instructs to stop driving the auger and cooling operation of the cooling cylinder when the measured time reaches a specified time. .
