DRIVE CONTROL DEVICE OF ICE-MAKING TRAY OF AUTOMATIC ICE-MAKING DEVICE

摘要

PROBLEM TO BE SOLVED: To operate a device efficiently by using a means for setting differently signals outputted by a state detection device that outputs a detection signal at ice-level detection positions of the starting edge, ending edge, and the middle of the rotary region of an ice-making tray. ;SOLUTION: An ice-making tray driving device 1 transfers a drive force from a drive motor 2 to an ice-making tray 3, for example, via a reduction gear, rotates the tray 3 from a horizontal position to the maximum twisting position, and inverts the rotation and returns to an original horizontal position after ice releasing. Also, a state detection device 4 consists of a tray position detection mechanism 5 that operates in linking with the ice-making tray drive device 1 and outputs a specific signal when the tray 3 is located at a starting edge position of an ending edge position in a rotation region where the horizontal position of the tray 3 is at the starting edge and the maximum twisting position is at the end edge, and an ice level detection mechanism 7 for outputting a different signal spending on the presence or absence of ice by detecting the amount of ice of an ice storage box 6 halfway during the rotation of the ice making tray 3.;COPYRIGHT: (C)1998,JPO
