にしたものがある。(Prior Art) Conventionally, in this type of auger-type ice maker, a pair of normally open type float switches are arranged above and below an ice making water tank, as shown in Japanese Utility Model Publication No. 10453/1983, for example. Then, when the ice storage detection switch detects a lack of water in the ice storage, the water supply valve is opened to supply ice making water from the water supply source to the ice making water tank, and the ice making water in the ice making water tank is increased to a predetermined amount. After closing both 70-tosuinochi, the ice-making operation is started, and the ice-making water from the ice-making water tank is frozen in the ice-making cylinder, and this frozen ice is drawn out from the ice-making cylinder by an auger and sequentially poured into the ice storage as small water. There is a device that stores ice and stops the ice-making operation when an ice storage detection switch detects that the amount of ice stored in the ice storage is sufficient as the ice-making water in the ice-making water tank decreases.

A problem arises in that water quality deteriorates. Further, if the above-mentioned impurities enter components such as bearings in the ice-making cylinder in a concentrated state, problems arise in that they adversely affect the components, such as quality deterioration. Also, for example, if foreign matter such as dirt or dust gets into the ice-making water in the ice-making water tank, this foreign matter will also get mixed in with the frozen ice in the ice-making cylinder.
As a result, not only the quality of the water deteriorates, but also problems such as unsanitary conditions occur.

It is opened by receiving AC voltage from L2. Therefore, the ice making water in the ice making cylinder body 20 and the ice making water tank 60 is drained from the drain pipe 20a and the drain valve D.
Water is drained outside through V. This drainage is done by switch 28
0 and continues while the determination with rNOJ is repeated. When the auxiliary timer finishes counting and the time Ta elapses, the microcomputer determines that all the ice-making water in the ice-making cylinder 20 and the ice-making water tank 6o has been drained.
The data controller 150 determines “rYES” in step 280,
At step 280a, the drainage output signal is made to disappear, and at step 280b, it is determined that rYESJ, and the relay fill R

Driven by AC voltage from L2. Therefore, the compressor 9° is driven by the compressor motor Me and starts a compression action. As a result, in the refrigeration cycle R, the refrigerant flows through the compressor 90, condenser 100, .
It begins to circulate through the receiver 110, the expansion valve 120, and the evaporator 3o. This means that the ice-making water in the ice-making cylinder 2o is cooled by the evaporator 3o, that is, the ice-making machine starts ice-making operation.

．． Discrimination with rNOJ at 320 and each step 330,
When the ice-making water in the ice-making cylinder 2o freezes into flakes while repeating the discrimination between rYEsJ and rYEsJ at step 240, the ice-making water is rotated upward by the spiral teeth 42 of the auger 4o as the auger 4o rotates. The ice is guided into the ice storage, compressed into rod-shaped water by each compression member 50, sequentially cut by a cutter 53, passed through a guide tube 54, and stored in the ice storage. On the other hand, the ice-making water in the ice-making water tank 60 flows into the ice-making cylinder 20 through the pipe 62. Thereafter, such ice making operation is continued. When the upper limit float switch Fu opens and the lower limit float switch F2 opens as the ice making water in the ice making water tank 60 decreases, the microcomputer 150 determines rNOJ in step 330 and advances the computer program to step 220a.

The ice-making water is discharged to the outside through the DV and the water pipe 20a, and then the ice-making water is resupplied into the ice-making cylinder 20 and the ice-making water tank 60 before shifting to ice-making operation. Even if concentrated impurities and foreign substances such as dirt and dust remain in the ice-making water in the water tank 6o, these concentrated impurities and foreign substances are removed from the ice-making water tank 60 and the ice-making cylinder during the first ice-making water supply as described above. 20 is washed and floats in the ice-making water, and is discharged to the outside together with the ice-making water when the ice-making water is drained.

is determined to be rYESJ in step 3101, and in step 340, F=Q is reset, and in the ice-making operation stop routine 350, the first and second motor output signals are set to predetermined third and fourth delay times T3. ．． Each will be extinguished at the end of T4. Then, the drive circuit 170 eliminates the relay coil Rx by eliminating the first motor output signal from the microcomputer 150, and the motor Mg and fan motor Mf switch each relay switch X1. It stops when X2 is opened. Therefore, the auger 4o and the air cooling fan 1008 stop. Further, the drive circuit 160 demagnetizes the relay coil Rv by eliminating the second motor output signal from the microcomputer 150, and the compressor motor Me stops by opening the relay switch W.

All the ice-making water in the ice-making water tank 6o is drained to the outside through the drain valve DV and the drain pipe 20a. Therefore, as described above, after the determination is made that it is rYESJ at step 310, it takes a long time until the steno knob 280b is determined that it is rYESj based on the opening of the ice storage detection switch s2 as the water in the ice storage decreases. Even if some time passes, impurities in the ice-making water will be concentrated in the ice-making cylinder 20 and the ice-making water tank 60 due to the above-mentioned drainage of the ice-making water in the ice-making cylinder 20 and the ice-making water tank 60.

層適確になされ得る。As a result, as described above, smooth operation of the bearing portion of the auger 40 and hygienic high-quality ice storage are achieved. Also, based on the end of the main timer, rYE is executed in step 7 block 320.
Even if it is determined that the
After the main timer is reset and started at step 300, the same arithmetic processing as that after the determination with rYEsj at step 300 is performed, and the auger 4o
Smooth operation of the bearing part and hygienic high-quality ice storage are achieved. Also, as described above, each step 250
, 300, 310, and 320, and then draining and watering are repeated, so that concentrated impurities and foreign substances in the ice-making cylinder 20 and the ice-making water tank 60 can be removed more accurately.

に同様の効果が得られる。In implementing the present invention, if step 340 is omitted, the water is drained only once, leading to savings in ice making water. Moreover, when the volume of the ice storage is small,
Since the interval between the determination timings of "YESJ" and "YESJ" in step 310 is relatively short, even if step 340 is omitted, substantially the same effect as in the above embodiment can be obtained while ensuring the saving of ice making water. .
