クルの1サイクルが終了し、再度ステップ204に進み、
以降このサイクルを繰返し自動的に製氷を行なう。First, in step 201, if the state of the horizontal position detecting means 9 is ON, the ice making container 1 can be determined to be horizontal, and the process proceeds to step 202. If it is determined in step 201 that the ice making container 1 is not horizontal, the process proceeds to step 203. Set ON so that the advance motor 6 operates. In step 202, the motor 6 is turned off, and the process proceeds to step 204. In step 204, it is determined whether the temperature of the temperature detecting means 2 is higher or lower than a set value. If it is determined in step 204 that the temperature is low, it can be determined that ice making has been completed, and the process proceeds to step 205 where the motor 6 is turned on. Therefore, the ice making container 1 is rotated. Then, the ice is released from the ice making container 1 by applying a twist in the twisting section 7. Therefore, the state of the position detecting means 8 is turned on in step 206, and it can be determined that the ice removal has been completed. In step 207, the motor 6 is continuously moved until the ice making container 1 becomes horizontal. Wait until 9 turns ON. Steps
In step 206 and step 207, the process returns to step 206 until both the position detecting means 8 and the horizontal position detecting means 9 are turned on. Step 2
When the horizontal position detecting means 9 is turned on at 07, the ice making container 1 is determined to be horizontal, and the motor 6 is stopped at step 208.
At step 209, the water supply pump motor 4 is operated to supply water to the empty ice making container 1, and at step 210, a timer is started and at step 211, the water supply pump motor 4 is operated until the time is up. When the timer times out in step 211, the water supply pump motor 4 is turned off in step 212. Water supply is completed as described above, one cycle of the ice making cycle is completed, and the process proceeds to step 204 again.
Thereafter, this cycle is repeated to automatically make ice.

For example, if a short power failure (within about 5 minutes) occurs immediately after the water supply in step 1 or the water supply in step 212, the control means
Since step 11 is restarted from step 201, the following inconvenience occurs. That is, immediately after the water supply or immediately after the water supply, if a short power failure occurs in a state where the temperature of the outer bottom surface of the ice making container 1 has not yet sufficiently risen, the process starts from step 201 and immediately proceeds to step 202. In step 204, it is determined that the temperature of the temperature detecting means 2 is lower than the set value, and
At 205, the motor 6 is turned on. Therefore, the ice making container 1 performs an ice releasing operation including rotation. Therefore, the water in the ice making container 1 may have spilled into the ice storage box below. There has been a problem that ice in the ice storage box is flooded with water and the ice becomes a large lump and becomes difficult to use.

で貯氷箱に落ちてしまう事が防止できる。Effect of the Invention According to the above-described configuration, when a short power failure occurs in water supply or immediately after water supply, even if the control means starts from the first step, the determination of ice making completion is made by first setting the temperature of the temperature detection means. If the temperature of the temperature detecting means is detected again after a certain time (for example, 30 minutes) even if the temperature is lower than the temperature, the temperature of the temperature detecting means is affected by the water in the ice making container (15 ° C.).
(30 ° C to 30 ° C), which is sufficiently high and judged to be higher than another set temperature, so it can be judged at this stage that ice making is not completed, and wait until the temperature of the temperature detection means becomes lower than another set temperature Is done. Therefore, the ice-removing operation is not performed, and even if a short power failure occurs immediately after the water supply or after the water supply, it is possible to prevent the water from falling into the ice storage box in a water state.

説明を省略する。尚ステップ212の後は、ステップ101に
戻り、以降この製氷サイクルを繰返し氷を生成する。In such a configuration, the operation will be described with reference to FIG. First, the process is started from step 201 by turning on the power, and after the motor 6 is turned off in step 202, the process proceeds to step 101. In step 101, the temperature of the temperature detecting means 2 is detected and compared with the set temperature T0. Here, if the temperature of the temperature detecting means 2 is high, the process waits in step 101 until the temperature becomes low. In step 101, the temperature of the temperature detecting means 2 is set to the set temperature T0.
If it is determined to be lower, the process proceeds to step 102 and the timer 16
Start. In step 103, it is confirmed whether the time of the timer 16 is a predetermined time or not. If the time is not up, the process waits until the time in step 103 is up. When the timer 16 times out in step 103, the process proceeds to step 104. In step 104, the temperature of the temperature detecting means 2 is confirmed again and compared with another set temperature T1. If the temperature of the temperature detecting means 2 is high in step 104, the process waits in step 104 until the temperature decreases, and if the temperature of the temperature detecting means 2 is low, step 205
Proceed to. Note that the set temperatures T0 and T1 have a relationship of T0> T1.
Since the contents of steps 205 to 212 are the same as in the conventional example, the description will be omitted. After step 212, the process returns to step 101, and thereafter, the ice making cycle is repeated to generate ice.

る。Therefore, even if there is a short power outage immediately after the water supply in step 211 or step 212 or immediately after the end of the water supply and the process starts from the first step and proceeds to step 101 for judging the completion of ice making, the temperature detecting means 2 is still cold in step 101 Even if it is determined that the temperature is lower than the temperature T0, and the process proceeds to step 102, there is a certain waiting time in step 103.
In the comparison with the set temperature T1, it is determined that the temperature of the temperature detecting means 2 is high. Therefore, in step 104, the water in the ice making container 1 is sufficiently cooled to change from water to ice in order to wait for the temperature of the temperature detecting means 2 to be lower than the set temperature T1. Ice is stored in the ice storage box 10.

After detecting the temperature, after a certain time elapses, the temperature detection means will not proceed to the next de-icing operation unless it is lower than another set temperature, so there is a short power outage immediately after water supply or water supply, and the temperature detection means is cold Even if it returns to the first step of the control means in the state, the ice is not immediately separated and after a certain period of time the temperature detecting means becomes sufficiently high. Do not go. Therefore, it is possible to provide a stable ice making operation without inconvenience that the ice making container goes to the ice removing operation by mistake and water is spilled.
