Then, the water flowing through the water-cooled condenser 3 is discharged to the outside of the ice making machine through the third drainage channel 63. A solenoid valve type water-saving valve 64 is provided in the third drainage channel 63.

In FIG. 2, the control device 66 of the auger type ice making machine is composed of a microcomputer and the like, and various electric parts are connected to the control device 66, but as the electric parts related to the present invention, , An ice storage switch 14 for detecting the amount of ice in the ice storage chamber and a water level switch 32 for detecting the water level of the water storage tank 24 are connected to the input side, while the water supply valve 23, the water storage tank drain valve 44, and the like are connected to the output side.

You are running the program. Further, the controller 66
It has a built-in timer that measures elapsed time, a counter that counts the number of repetitions n (initial setting is 0), and so on.

The main flow of cleaning of the auger type ice making machine constructed as above will be described with reference to the flow chart of FIG. At step 0, the auger ice machine is powered on. When the power is turned on, the valves 23, 44 and 64 are closed and the compressor 1, the blower 8 and the auger motor 12 are stopped. And step 1
At, the controller 66 outputs an open signal to the water supply valve 23 to open the water supply valve 23. Then, water flows from the water supply port 21 into the water storage tank 24 and is stored therein, and the water level in the water storage tank 24 rises. Then, in step 2, the controller 66 checks the output signal of the water level switch 32. Then, when the water level of the water storage tank 24 becomes full and the water level switch 32 is turned ON, an ON signal which is a water full signal of the water level switch 32 is input to the control device 66, and the process goes to step 3. On the other hand, in step 2, when the output of the water level switch 32 is the OFF signal, the process returns to step 2 and waits until the water level switch 32 is turned on.

In step 3, the control device 66 outputs a close signal to the water supply valve 23, closes the water supply valve 23, and proceeds to step 4. In step 4, the controller 66 outputs an open signal to the drain valve 44 to open the drain valve 44, and the controller 66 measures the first drainage set time (for example, about 1 minute) with a timer, and after the measurement. , Outputs a close signal to the drain valve 44 and closes the drain valve 44. The first drainage set time is preset in the controller 66. The initial cleaning process is completed in steps 1 to 4. The initial cleaning process includes the initial water storage starting process of step 1 and step 2
And the initial water storage end process of step 3 and the initial drainage process of step 4. Then, after this initial cleaning process, the repeated cleaning process from step 5 to step 12 is started. In this way, the cleaning process includes the initial cleaning process and the repeated cleaning process.

In step 5, the controller 66 outputs an open signal to the water supply valve 23 to open the water supply valve 23. Then, water flows from the water supply port 21 into the water storage tank 24 and is stored therein, and the water level in the water storage tank 24 rises. Then, in step 6, the control device 66 determines how many times the number of repetitions n that has been repeated so far is judged. In the case of the first time, the number of repetitions n is 0. After the first time and until the repeat setting number N (for example, 3 times) is reached, go to step 8 and when the repeat setting number N is reached, step 1
Go to 3. The number of times N of repetition setting is preset in the control device 66.

In step 7, the controller 66 outputs an operation signal to the auger motor 12 to operate the auger motor 12 and rotate the auger 11. Then go to step 8. In step 8, controller 66 checks the output signal of water level switch 32. Then, the water level of the water storage tank 24 becomes full and the water level switch 32
When is turned ON, an ON signal which is a full water signal of the water level switch 32 is input to the control device 66, and the process goes to step 9. On the other hand, when the output of the water level switch 32 is the OFF signal in step 8, the process returns to step 8 and waits until the water level switch 32 is turned on.

In step 9, the control device 66 outputs a close signal to the water supply valve 23, closes the water supply valve 23, and proceeds to step 10. In step 10, the control device 66 measures the full-water keeping set time (for example, about 2 minutes) with a timer, and after the measurement, goes to step 11. The full water maintenance setting time is preset in the control device 66. In step 11, the control device 66 outputs an open signal to the drainage valve 44 to open the drainage valve 44, and the control device 66 measures the repetition drainage set time (for example, about 1 minute) with a timer, and measures it. After that, a closing signal is output to the drain valve 44 to close the drain valve 44. The drainage setting time during repetition is preset in the control device 66. Then go to step 12. At step 12, 1 is added to the number of repetitions n.
In the case of the first time, the number of repetitions n changes from 0 to 1.

Then, the process returns to step 5. In step 5, the water supply valve 23 is opened, and in step 6, since the number of times of repetition n is 1, this time, the process goes to step 8, and in step 12, the number of times of repetition n is incremented by 1 and the step 5 is repeated.
Return to. Then, the process is repeated until the repeat count n reaches the repeat set count N. In this way, the repeated cleaning process is constituted by steps 5 to 12, and the repeated cleaning process includes the repeated water storage start process of step 5 and step 7.
Auger motor operation start step, step 8 and step 9 water storage end step during repetition, step 10 and step 11 water discharge step during repetition, water storage start step during repetition, water storage end step during repetition, and water replenishment step during repetition It has a repeating process of repeating the returning drainage process a plurality of times before the ice making operation. Then, in step 12, 1 is added to the number of times of repetition n, and the new number of times of repetition n becomes the number of times of repetition setting N. In the subsequent step 6, the controller 66 sets the number of times of repetition n to the number of times of repetition setting N. If so, go to step 13.

At step 13, the number of repetitions n is reset to 0, and the process goes to step 14. In step 14, controller 66 checks the output signal of water level switch 32. Then, when the water level of the water storage tank 24 becomes full and the water level switch 32 is turned ON, the ON signal which is a water full signal of the water level switch 32 is turned on.
Input 6 and go to step 15. On the other hand, step 1
When the output of the water level switch 32 is the OFF signal in 4, the flow returns to step 14 and the water level switch 32 is turned on.
Wait until.

In step 15, the ice making process of the ice making operation is started. That is, the control device 66 outputs an operation signal to the compressor 1 and the blower 8 to operate them, and
An open signal is output to the water-saving valve 64 to open it. Then, ice is made in the ice making section of the auger type ice making machine, and this ice is stored in the ice storage chamber. Then, go to step 16. Step 16
In, the control device 66 determines whether or not the ice storage switch 14 of the ice storage chamber has turned to the ON signal which is a full ice signal. When the control device 66 turns to the ON signal, the process goes to step 17 to enter the ice storage process. On the other hand, in step 16, the ice storage switch 14
Is an OFF signal which is a deicing signal, step 16
Then, the ice making process is continued to make ice. During the ice making process, the control device 66 controls the opening and closing of the water supply valve 23 based on the output of the water level switch 32 so that the water level of the water storage tank 24 becomes a substantially constant full water level.

In step 17, the ice storage step of the ice making operation is started. That is, the control device 66 controls the compressor 1,
A stop signal is output to the blower 8 and the auger motor 12 to stop them, and a closing signal is output to the water-saving valve 64 to close it. Then, ice making stops. In addition, the ice storage room is filled with ice. The ice making operation consists of an ice making process and an ice storing process. Then go from step 17 to step 18. In step 18, the control device 66 causes the ice storage switch 14 of the ice storage chamber to output an ice reduction signal O
It is determined whether or not the FF signal is output, and the output of the ice storage switch 14 is OF when the ice is taken out from the ice storage chamber.
When it becomes the F signal, the process returns to step 1 to enter the washing process, and after this washing process, the ice making operation is started. On the other hand, in step 18, when the ice storage switch 14 is the ON signal which is the full ice signal, the process returns to step 18 and the ice storage process, that is, the full ice state is maintained.

Thus, in this embodiment, before the ice making step of the ice making operation (that is, when the power is turned on, or
At the time of switching from the ice storage step to the ice making step), as the first cleaning step, the water inlet 41 to the water outlet 42 of the cooling cylinder 9 are in a state where the auger motor 12 is not operating (that is, the auger 11 is not rotating). Water is flowing to. Since the auger 11 is stopped in this way, dust or the like during piping work does not flow largely into the cooling cylinder 9, but immediately passes from the water inlet 41 at the bottom of the cooling cylinder 9 through the water outlet 42. Is discharged. Therefore, it is possible to prevent clogging of dust and the like in the cooling cylinder 9.

After this initial cleaning step, a repeated cleaning step is performed. By the way, before the start of the ice making operation, if ice adheres to the inside of the cooling cylinder 9 and becomes clogged (for example, when the period of the ice storing step is short, that is, immediately after the ice making step enters the ice storing step, the ice making step is switched to the next ice making step. When the inner surface of the cooling cylinder 9 or the auger 11 is dry, the water from the water storage tank 24 may not smoothly flow into the upper portion of the cooling cylinder 9. Even in such a case, by repeating the washing process, that is, in the state where the auger 11 is rotated, water injection and drainage are repeated to melt the attached ice, or to cool the inner surface of the cooling cylinder 9 and the auger 11. You can moisten it. As a result, after the repeated cleaning process, water can smoothly flow into the upper portion of the cooling cylinder 9, and the generation of abnormal noise can be prevented.

In this way, the control device 6 which is the control means
No. 6 checks the output signal of the water level switch after outputting the open signal to the water supply valve and opening the water supply valve to store water in the water storage tank before starting the ice making operation and after executing the first water storage start means. , When the output signal of the water level switch is a full signal, a closing signal is output to the water supply valve and the water supply valve is closed, and after the execution of this first water storage ending means,
The first drainage execution means for outputting an open signal to the drain valve to open the drain valve, outputting a close signal to the water supply valve to close the drain valve after the preset first drainage set time has elapsed, and the first drainage execution means. After the execution of the drainage execution means, an open signal is output to the water supply valve to open the water supply valve to store water in the water tank, and to output the operation signal to the auger motor after execution of the water storage start means at the time of repetition Then, the output signal of the water level switch is checked after execution of the auger motor operation starting means for operating the auger motor and the water retention start means for repetition, and if the output signal of the water level switch is a full signal, a closing signal is output to the water supply valve. To close the water supply valve and to repeat the water storage end means, and after the preset water storage end time has elapsed, when the preset full water retention setting time has elapsed, an open signal is output to the drain valve to open the drain valve. , In advance Repeated drainage execution means for outputting a close signal to the drainage valve to close the drainage valve after a lapse of the set repeated drainage time, the repeated water storage start means, and the repeated water storage end means Also, it is equipped with a repeating means for repeating the drainage executing means during repeating a plurality of times before the ice making operation. As described above, the control device includes, in addition to the above-mentioned means, means for executing each operation corresponding to each operation to be executed. Moreover, it is not always necessary to have all of the means described above.

(3) The washing process and the flow of the ice making operation can be appropriately changed. (4) It is not always necessary to provide both the air-cooled condenser 2 and the water-cooled condenser 3, and it is possible to use only one of them. (5) The form and structure of the ice storage sensor and the water level sensor can be appropriately changed as long as the ice storage amount and the water level can be detected.

[0028]

According to the auger type ice making machine and its cleaning method of the present invention, water is stored in the water storage tank, the auger motor is operated to rotate the auger, and after the elapse of the full water retention setting time, the drainage setting time is passed. Open the drain valve and drain the water several times before starting the ice making operation. By repeating pouring and draining while this auger is rotating,
It is possible to melt the ice attached to the cooling cylinder or the auger, and to moisten the inner surface of the cooling cylinder or the auger. As a result, after the repeated washing process of pouring and draining water, water can smoothly flow into the upper part of the cooling cylinder, and generation of abnormal noise can be prevented. Moreover, since it is not necessary to form holes in the auger or the cooling cylinder, the manufacturing cost can be reduced.

The initial cleaning may be performed before the repeated cleaning step of the pouring and draining. In this first washing, after water is stored in the water storage tank, the drain valve is opened for draining during the first drainage setting time. In such a case, dust and the like during piping work do not largely flow into the cooling cylinder because the auger does not rotate, and are immediately discharged from the water inlet of the cooling cylinder through the water outlet. . Therefore, it is possible to prevent clogging of dust and the like in the cooling cylinder as much as possible.
