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).
Claims8
An auger type ice making machine comprising:
- a geared motor for driving an auger;
- an RPM detecting means for detecting RPM of a rotor of the geared motor;
- and
