った。(c) Problems to be Solved by the Invention In this prior art, ice that has abnormally frozen inside the cooling cylinder is melted using hot gas and then drained, but the heat from the hot gas is first passed through the cooling cylinder. to melt the ice that is in contact with the inner surface of the cylinder. As a result, the melted area forms a cavity, and the heat of the hot gas is then transferred to the cooling cylinder and then to the ice via the cavity. That is, ice melting using hot gas has the problem that heat conduction to the ice gradually decreases when cavities are formed, so it is not suitable for uniform ice melting and takes a long time to melt ice.

を一定に保持する。During the ice-making operation, the ice that has grown on the inner surface of the cooling cylinder (1) is compressed by the rotation of the auger (6) and passed through the compression passage (Il).
1, where it is compressed into hard ice pieces, and then continuously released from the discharge cylinder α2. 16B) is opened, the excitation of the first relay c!D is released, the normally closed first relay contact (21B) is closed, and the water supply valve (171) is opened to replenish water to the water tank αJ and return to the predetermined water level again. When it rises to the upper reed switch (16B)

When abnormal freezing occurs within the cooling cylinder (1), the evaporation temperature decreases, and when the thermostat detects a predetermined abnormal low temperature of the evaporation temperature, its contact switches to the supercooling contact (23B).

Further, by switching the thermostat (c), the fourth relay (c) is energized to close the normally open fourth relay contact (26A) and open the drain valve α9. Furthermore, by closing the fourth relay contact (26A).

ている氷は徐々に均一的に融解されて排水される。Therefore, the low-temperature water present in the cooling cylinder (11) together with abnormally frozen ice is drained from the drain pipe section, and instead, tap water with a temperature higher than at least the low-temperature water is discharged from the water storage tank 0 into the water supply pipe. Water is supplied to the cooling cylinder (1) from the α water. Due to the heat sensitivity of this inflow water, abnormally frozen ice in the cooling cylinder (1) is gradually and uniformly melted and drained.

続する。As mentioned above, the abnormal freezing of the cooling cylinder (11) is released due to the heat sensitivity of the water flowing in from the water storage tank α3.
If the thermostat returns from the supercooled contact (23B) to the normal cooled contact (23A), or if the return force has not yet passed the set time of the timer (c), the timer contact (28A) closes at this time. Therefore, the 5th relay □□□ is energized and the normally closed 5th relay contact (27B) is open, so the compressor (2), blower (3) and auger motor α [do not start, and the water is drained. Valve a9 also remains open via the normally closed third relay contact (25B).

を開路して排水弁ａ９を閉じる。On the other hand, if the thermostat (c) returns to normal after the timer set time has elapsed, at this time the timer contact (28
A) is open, the 5th relay forehead is de-energized, and the normally closed 5th relay contact (27B) is closed, so in this state the thermostat normally returns to the cooling contact (23A). Waiting for this, auger motor 01 starts, the third relay (c) is energized, and the normally open third relay contact (25A)
The circuit is closed and the compressor (2) and blower (3) are started to restart ice making operation, and the normally closed third relay contact (25B)
Open the circuit and close the drain valve a9.

３リレー接点（２５Ｂ）を閉路して排水弁α９を開く。The above description is a detailed explanation of the method for canceling supercooling when the thermostat detects supercooling of the cooling cylinder (1). In addition, the present invention also provides cooling cylinder (1) by an auger motor (overcurrent detection device G!4 for detecting overcurrent of II).
can detect supercooling. That is, when abnormal freezing occurs in the cooling cylinder (1), the load on the auger motor αG increases and a JIIC overcurrent flows, and when the overcurrent detection device (2) detects this, the auger motor αG is stopped. The third relay (c) is de-energized and the normally open third relay contact (25A) is opened to open the compressor (2) and the blower (
3) is deactivated to stop the ice making operation, the normally closed third relay contact (25B) is closed, and the drain valve α9 is opened.

タートする。At the same time, the fourth relay 4 is energized and closes the normally open fourth relay contact (26A), and the fifth relay ■ is energized and the normally open fifth relay contact (2) A) is closed, making it normally open. When the fifth relay contact (27B) opens, the timer starts.

開は制御される。The subsequent method of canceling supercooling is the same as described above, and will therefore be omitted. Therefore, the overcurrent detection device (foundation) can be of the automatic return type or the manual return type, but in any case, the water will be drained depending on whether the overcurrent detection device returns to normal or the time set on the timer elapses later. Stopping the operation and restarting the ice making operation is controlled.
