1. An ice making apparatus of a refrigerator, comprising:
an ice tray that accommodates water for making ice; a sensor installed on a lower surface of the ice tray; a sensor wire having a first end connected to the sensor and a second end configured to be connected to a controller of the refrigerator to transfer data therebetween; a driver provided at a first end of the ice tray; a drive rotational shaft formed on the first end of the ice tray and coupled to the driver to be rotated by the driver; a rotational shaft support device provided at a second end of the ice tray opposite the first end thereof, that supports the second end of the ice tray, the rotational shaft support device having a rotational shaft hole; and a support rotational shaft formed on the second end of the ice tray and inserted into the rotational shaft hole of the rotational shaft support device, the support rotational shaft having a through hole formed therein that guides the sensor wire therethrough such that the sensor wire is prevented from being twisted or cut off when the ice tray is rotated, wherein the first end of the sensor wire includes a connection terminal connected to the sensor, the connection terminal being thicker than the through hole, wherein the support rotational shaft includes:
a first through portion fixed to the second end of the ice tray;a second through portion that extends outward from the first through portion and is coupled to the rotational shaft hole of the rotational shaft support device to be rotatable;a stop protrusion provided between the first and second through portions, that engages the rotational shaft hole of the rotational shaft support device to limit lateral movement of the support rotational shaft;a first cutaway formed in the first through portion and the stop protrusion, that exposes a corresponding portion of the through hole and is configured to allow an intermediate portion of the sensor wire between the first end and the second end of the sensor wire to be withdrawn out of the through hole; anda second cutaway formed in the second through portion, that exposes a corresponding portion of the through hole and is configured to receive the intermediate portion between the first end and the second end of the sensor wire, wherein a width of the second cutaway is less than a diameter of the sensor wire such that the sensor wire is press-fit into the through hole through the second cutaway, to be prevented from being released therefrom, wherein a width of the first cutaway is greater than the diameter of the sensor wire to allow for easy insertion and withdrawal of the sensor wire, wherein a diameter of the through hole is greater than the width of the first cutaway, the width of the second cutaway, and the diameter of the sensor wire, and wherein the second cutaway is blocked by the rotational shaft support device when the support rotational shaft is inserted into the rotational shaft hole. |
