  • Patent number: 6915647
    Abstract: An auger-type ice making machine has an abnormality detecting device which detects a freezing of an ice-scraping auger on the basis of a hunting of current flowing through an auger motor 25. Current flowing through the auger motor 25 is taken out by a current-voltage converter 45, and an instantaneous value of the taken-out voltage,waveform every predetermined time is A/D converted by an A/D converter 52 which is provided at a controller board 50.
    Type: Grant
    Filed: May 21, 2003
    Date of Patent: July 12, 2005
