Abstract:
1. An ice level detection structure for ice makers located on an ice maker to detect an ice level of ice cubes actually stored in an ice trough, comprising: a detection rack which is located above the ice trough and has a transmission shaft and a detection portion connected to the transmission shaft; and a motor located in the ice maker and a transmission means interposed between the motor and the transmission shaft to transmit driving power output from the motor to drive the transmission shaft and the detection portion to generate a detection displacement in the ice trough that has a return position and a detection position to allow the detection portion to accurately judge the ice level of the ice cubes actually stored in the ice trough; the transmission means including a transmission member driven by the motor, a crank element driven by the transmission member and a driven member bridging the crank element and the transmission shaft, the crank element having an axis portion, a first lever coupled with the transmission member and a second lever coupled with the driven member, the first lever being driven by the transmission member to turn about the axis portion so that the second lever generates an eccentric displacement to drive the driven member; the crank element further having a third lever turnable about the axis portion to generate a second eccentric displacement while the first lever is turning, an ON/OFF switch being located within the second eccentric displacement of the third lever.
