Description of the Related Art An evaporating tube led out of a freezing system is disposed on an ice making plate which stands vertically, and ice making water is sprinkled and supplied to the ice making plate cooled by the evaporating tube to produce a plate-like ice block. 2. Description of the Related Art A falling-type automatic ice maker which peels off an obtained ice block and discharges it is widely used because of its simple structure and low ice making cost. This automatic ice making machine is provided with an ice making water tank for storing a required amount of ice making water.In the ice making operation, the ice making water in the tank is pumped by an ice making water circulating pump and supplied to the ice making plate, so that the ice making which did not freeze is performed. After the water is collected in the tank, a forced circulation mechanism for sending the water to the ice making plate again is adopted. Further, when the ice making operation on the ice making plate is detected and the operation is shifted from the ice making operation to the de-icing operation, de-icing water is scattered and supplied to the back surface of the ice making plate to promote the melting of the frozen surface with the ice blocks, and the de-icing water is removed. The ice is collected in an ice making water tank and used as ice making water in the next ice making operation.

った製氷水(製氷残水)を機外に排出している。During the ice making operation, the ice making water in the ice making water tank is pumped to the ice making plate, and the ice making water that has not been frozen is recovered in the ice making water tank.
In an automatic ice making machine employing a circulation mechanism of ice making water for pumping again to the ice making plate, the ice making operation progresses (ice is generated on the ice making plate) and the ice making water in the ice making water tank is reduced. It is known that the concentration of impurities such as silica contained in ice making water increases. If the ice making water having the higher impurity concentration is used for ice making, cloudy ice containing impurities may be generated. Therefore, a drainage pump is provided in a drainage pipe connected to the ice making water tank, and the pump is operated when the ice making operation is completed, thereby discharging the ice making water (ice making residual water) having an increased impurity concentration outside the machine. are doing.

問題を招くおそれがある。[0004] In this case, when the ice-making residual water having an increased impurity concentration flows through the drainage pump, impurities such as silica contained in the ice-making residual water precipitate in the pump and adhere to the impeller and the like. Each time the above-described drainage operation is repeated, the amount of deposits increases, impeding smooth rotation of the impeller, or causing a malfunction such as being in a locked state, thereby making it impossible to discharge the ice making water. This can lead to problems.

て、製氷水の供給不良を来たす難点も指摘される。[0005] In many cases, the user cannot be aware that the ice making residual water cannot be discharged by the drain pump. In this case, the ice making tank in which the concentration of impurities remaining in the ice making water tank is high is increased. Residual water mixes with deicing water used as the next ice making water that is newly supplied to the tank. In other words, the impurity concentration of the ice making water used next becomes higher than the normal ice making water (de-icing water supplied after the ice making remaining water is discharged), and the ice making is performed in such a state that the ice making remaining water cannot be discharged. When the operation and the deicing operation are repeated, an ice block mixed with impurities is generated on the ice making plate.
The ice mass becomes fragile or cloudy, and its commercial value is reduced. Furthermore, the ice making water having a high impurity concentration is circulated and supplied to the ice making part, so that impurities adhere to the inside of a path for supplying the ice making water to the ice making part with time, thereby preventing the supply of ice making water from being defective. The upcoming difficulties are also pointed out.

Upon detection, the control device 50 receives the detection signal from the means 52 and controls the drainage pump 28 to perform a cleaning operation for a predetermined time after the completion of the deicing operation. That is, the deicing water (next ice making water) stored in the ice making water tank 18 by the deicing operation is discharged outside the machine after flowing through the pump 28 by the operation of the drainage pump 28. At this time, since the deicing water flowing through the drain pump 28 is water having a low impurity concentration such as silica, the deposits deposited in the drain pump 28 can be washed out by repeating the above-described normal cycle operation. Therefore, it is possible to prevent an increase in the amount of deposits in the drain pump 28, which hinders smooth rotation of the impeller, or prevents a malfunction such as locking.

The remaining ice making water having an increased impurity concentration therein is surely prevented from being mixed with deicing water used as the next ice making water newly supplied to the tank 18. Therefore, it is possible to prevent the formation of cloudy ice in the ice making unit 10 and the occurrence of a situation in which the water sprinkling holes of the ice making water sprinkling pipe 16 are clogged with impurities to cause a supply failure of the ice making water.

It was distributed and washed inside.
That is, since the deicing water has a low impurity concentration, the deposits deposited in the drain pump can be washed out by repeating the normal cycle operation. Therefore, it is possible to prevent the amount of deposits in the drain pump from increasing and impeding the smooth rotation of the impeller, or to prevent a malfunction such as a locked state from occurring. Further, since the drain pump can be prevented from being in an operation failure state, the ice making residual water having an increased impurity concentration remaining in the ice making water tank is used as the next ice making water to be newly supplied to the tank. It does not mix with the deicing water used. Therefore, it is possible to prevent the generation of cloudy ice in the ice making section and the occurrence of a situation in which the supply path of the ice making water is clogged with impurities and the supply of the ice making water is poor.
