A protecting device of an auger ice-making machine which enables obtaining high responsiveness to detection of an abnormality, and identification of abnormal/normal stops. <??>The protecting device 42 has a rotating-speed detector 28 for detecting the rotating speed of the auger motor AM, and an electric current detector 38 for detecting the electric current value of the auger motor AM. The machine is brought to a total stop when the protecting circuit 36 of the protecting device 42 detects that the first detection value obtained by the rotating-speed detector 28 is equal to or less than a first threshold value. The protecting device 42 is also constituted so as to activate display/indication means 40 to display/indicate an abnormality if the second detection value obtained by the electric current detector 38 when the first detection value is equal to or less than the first threshold value exceeds a second threshold value. <IMAGE> |
