    • 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 is 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.

    • 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.
    • 一种能够获得对异常检测的高响应性以及异常/正常停止的识别的螺旋式制冰机的保护装置。 保护装置42具有用于检测螺旋电动机AM的转速的转速检测器28以及用于检测螺旋电动机AM的电流值的电流检测器38。 当保护装置42的保护电路36检测到由转速检测器28获得的第一检测值等于或小于第一阈值时,机器总共停止。 如果在第一检测值等于或小于第一阈值的情况下由电流检测器38获得的第二检测值超过的情况下,保护装置42也构成为启动显示/指示装置40以显示/指示异常 第二阈值。
