Abstract: An auger type ice machine in which the load on a geared motor and an upper bearing is mitigated by detecting the load on an auger. A geared motor (9) disposed below a cylinder (1). A rotor (12) of the geared motor has an output shaft (13). A pulse encoder (14) is provided on the output shaft (13). The geared motor (9) is connected with a geared motor power supply (16) through a relay (15). Similarly, a compressor (3) is connected with a compressor power supply (18) through a relay (17). The relays (15) and (17) are controlled by a control portion (19). The control portion (19) controls the relays (15) and (17) according to a signal inputted from the pulse encoder (14).

Abstract: An ice making machine in which upon starting of an ice making operation, a water level detecting switch starts measurement, and a water-supply-stop time T1 is compared with a reference time T2. When the water-supply-stop time T1 is not longer than the reference time T2, it is determined that the ice making machine is an excessive-ice-making state, and control is performed so as to reduce the RPM of a fan motor for cooling a condenser.
