If the state is N, that is, "YES", the electric motor 8 is stopped if it is running, and if it is stopped, it is left as it is (step 3). Next, the ice making timer 15 is started (step 4) and waits until the time is up (step 5). When the time is up and a time (for example, 120 minutes) which is considered to be sufficiently completed has passed, it is next judged whether or not the temperature of the temperature detector 2 is lower than the set value (step 6). That is, if “NO”, the process waits until it becomes low.

で待つ。If it is determined that the temperature is low and ice making is completed, that is, if "YES", the operation of the electric motor 8 is started.
(Step 7). As a result, the ice tray 1 is rotated and twisted by the twisting arm 6 to drop ice from the ice tray 1. At this time, it is judged whether or not the twisting motion completion position detector 11 is in the ON state (step 8), and if it is not in the ON state, that is, “NO”, the operation of the electric motor 8 is continued. If it is in the ON state, that is, "YES", it is determined that the ice removal is completed, the electric motor 8 is continuously operated until the ice tray 1 becomes horizontal, and the horizontal position detector 10 waits until it becomes the ON state.

If it is not turned on, that is, if "NO", the operation of the electric motor 8 is continued. When the horizontal position detector 10 is turned on, that is, "YES", it is determined that the ice tray 1 has returned to the horizontal position, and the electric motor 8 is stopped (step 10). Then, in order to supply water to the empty ice tray 1, the water supply motor pump 4 is operated (step 11) and the water supply timer 14 is started (step 12) until the time is up (for example, 8 seconds elapse). Until) The water supply motor pump 4 is operated.

When the water supply is completed, one cycle of the ice making cycle ends, and the process proceeds to step 4 again, and thereafter this cycle is repeated to automatically make ice.
