  • Ice discharging structure of ice making mechanism
    Patent number: 7444828
    Abstract: An ice discharging structure of an ice making mechanism for discharging an ice block from the ice making mechanism reliably regardless of the weight of the ice block. An ice making mechanism of an ice making machine comprises an ice making section case in which an opening closed by a separator openably and closably is provided. The ice making section case comprises an ice chute inclined downward to the opening of the ice making section case, provided between an ice making section 16 and a sprinkler, for leading an ice block fallen from an ice making chamber to the opening. On an end face of the ice chute, a first rib is horizontally provided in a width direction of the end face, and a top thereof is in line contact with an inner face of the separator.
