Claims

[Scope of utility model registration request]

(1) Relay X3 that is energized by water level detection to stop the water supply and demagnetized by water storage detection: and generates a gear motor drive signal immediately after inputting the excitation signal of the relay, and generates a compressor drive signal after a certain period of time. an auger-type ice maker comprising: a timer circuit that generates a compressor stop signal after a certain period of time after inputting the demagnetizing signal of the relay, and further generates a gear motor stop signal after a certain period of time. control circuit.

(2) The relay has first and second normally open contacts and a normally closed contact, and the first palm open contact is connected in series with a lower float normally open contact of a water level switch that detects the water level. A series connection body is connected in parallel with the upper float normally open contact of the water level switch, and the parallel connection body is connected in series with the relay and a normally closed ice storage switch that detects water accumulation, and the normally closed contact is connected in series with the water supply valve and the water storage switch, and the second normally open contact generates an excitation signal and a demagnetization signal for the relay, the auger ice maker according to claim 1, which is registered as a utility model. control circuit.

(3) The gear motor drive signal and stop signal are signals that respectively energize and demagnetize a relay having a normally open contact that is connected in series with the gear motor, and the compressor drive signal and stop signal are signals that are connected in series with the compressor. A control circuit for an auger-type ice maker according to claim 1, which is a signal for respectively energizing and demagnetizing relays having normally open contacts.

(4) Another normally closed ice storage switch is provided to detect an abnormal water storage condition when the water storage switch does not operate normally, and when the water storage switch is activated, the timer circuit immediately shuts down the compressor and gear motor. A control circuit for an auger-type ice maker according to claim 1, which generates a stop signal when the ice maker stops.
