(c) Problems to be Solved by the Invention In such prior art, when the external release of ice is cut off for a long time, a considerable amount of ice melts in the ice storage, and this melted water flows through the water guide hole into water. The ice will be collected in a tank, but this melting of the ice will leave uneven and very poor quality ice in the ice storage.

By the way, ice machines equipped with an automatic ice removal function are installed in hotels, hospitals, etc., so that customers can freely take out the ice. However, as mentioned above, it is undesirable for customers to be supplied with ice that has melted and deteriorated in quality. The company used the cumbersome method of checking the status of

In view of this, the present invention provides means for determining and notifying the condition of ice whose quality has deteriorated in the ice storage due to ice melting, etc., thereby prompting the manager to take appropriate measures. , provides an ice making machine that is intended to reduce customer withdrawals of poor quality ice.

(d) Means for Solving the Problems In order to achieve the above object, the present invention includes an ice making mechanism, an ice storage for storing ice produced by the ice making mechanism, and a bottom part of the ice storage, which includes: An ice maker equipped with an ice transport mechanism that transfers ice in an ice storage to an ice discharge port in conjunction with an ice transport motor, an ice transport switch having a normally closed contact and a normally open contact, and an ice transport switch located at the normally closed contact. an alarm timer that performs a timing operation when the switch is in a normally open contact position; an alarm device that operates when the alarm timer continuously measures a predetermined time; It's an ice machine.

(E) Effect According to the present invention, when ice is not taken out for a predetermined period of time, the output from the alarm timer 26 lights up the LED 27 as an alarm device, and the ice in the ice storage 6 melts and its quality deteriorates. It is possible to notify the administrator of the decrease and prompt the administrator to take appropriate action.

(f) Examples Examples of the present invention will be described below with reference to the drawings. FIG. 1 is a main electrical circuit diagram of the ice maker of the present invention.
Figure 2 is a longitudinal sectional view showing the internal structure of the ice maker, Figure 3
The figure shows a front view of the ice-making machine, and an ice-making mechanism 2 is disposed at the top inside a main body 1 having a heat-insulating structure.
This ice-making mechanism 2 circulates water supplied to a water storage tank 3 to a water sprinkler 4, and flows this water onto an ice-making surface 5.
It is structured to freeze a predetermined amount of ice here, and the ice produced by the ice making mechanism 2 falls into an ice storage 6 defined at the lower part of the main body 1 and is stored therein. A long groove 7 formed at the bottom of the ice storage 6 is highly inclined toward an ice discharge port 8 formed on the front surface of the main body 1, and an ice transport mechanism 1 that is interlocked with a transport motor 9 is provided in the long groove 7.
0 is placed. The ice transport mechanism 10 has a front end connected to an output shaft of a transport motor 9, and a rear end supported by a housing 11 fitted into the main body 1. Furthermore, a stirring member 13 for preventing bridging is disposed in the upper part of the ice storage 6 and is interlocked with a stirring motor 12 . Additionally, an ice outlet cover 1 covering the ice outlet 8 is provided.
A drain pipe 15 is disposed below 4, and a drain hose 16 extending from this drain pipe 18 extends from a drain port 17 formed at the lowest part of the long groove 7.
It is structured so that it joins with a drain pipe 19 extending from the water storage tank 3 and drains the water all at once. Further, a machine room 20 defined below the main body 1
An electric compressor 21, a condenser 22, and a blower 23 are disposed as a refrigeration device for the ice making mechanism 2.

Next, the electric circuit will be explained. The ice take-out switch 24 is linked to the ice take-out button 25 provided on the front panel 1A of the main body 1, and the contact is changed to the normally closed contact 2.
4A and normally open contacts 24B and 24C,
An alarm timer 26 is connected in series with the normally closed contact 24A of the ice carry-out switch 24 , and the carry-out motor 9 is connected in series with the normally open contact 24B. The alarm timer 26 is set to a predetermined time period (for example, 48
When the time (time) is continuously measured, an output is generated that lights up an LED 27 as an alarm device, and it is reset if the power supply is cut off before a predetermined period of time has elapsed. Further, the stirring motor 12 is connected in series with the normally open contact 24C of the ice removal switch 24 , and at a predetermined period (for example, 30 times per hour).
Bridge prevention timer 28 that closes the contact in seconds)
It is also connected in series with the timer contact 28A.

Next, the operation of the present invention will be explained. When removing ice stored in the ice storage 6, when the ice removal button 25 is pressed, the ice removal switch 24 is activated in conjunction with this.
The contact is switched from the normally closed contact 24A to the normally open contact 24B, and at the same time, the normally open contact 24C is also closed. As a result, the carry-out motor 9 is started, the ice carry-out mechanism 10 is rotated, and the ice is transferred toward the ice discharge port 8 and discharged into a suitable container placed below the ice outlet cover 14. This ice release operation continues while the ice removal button 25 is pressed. On the other hand, a stirring member 13 interlocked with the stirring motor 12 rotates in order to prevent the ice in the ice storage 6 from freezing together.

When the ice removal button 25 is released, the contact of the ice removal switch 24 is again switched from the normally open contact 24B to the normally closed contact 24A, and the normally open contact 24C is also opened. Therefore, the unloading motor 9 and the stirring motor 12 are stopped, and the ice unloading operation and the ice stirring operation are stopped.

By the way, the ice removal switch 24 is a normally closed contact 24.
When switched to A, the alarm timer 26 starts timing operation, and when a predetermined period of time has passed continuously, the LED 27 lights up due to the output of the alarm timer 26, notifying the manager of the deterioration in the quality of ice in the ice storage 6. do. That is, the fact that the alarm timer 26 performs a timing operation means that no ice is taken out during this period, and the ice in the ice storage 6 progresses to melt and the quality deteriorates. Therefore, as described above, when ice is not removed for a predetermined period of time, the output from the alarm timer 26 causes the LED to
27 is turned on to notify the administrator of the deterioration in quality. When the LED 27 lights up, the manager can immediately press the ice removal button 25 to collect and discard the ice in the ice storage 6 that has deteriorated in quality.

(G) Effects of the Invention As described above, the present invention enables the management of ice storage without the need for the manager to take out the ice and investigate the condition of the ice in the ice storage.
It is possible to notify the manager of the deterioration in the quality of ice in the ice storage, which allows the manager to collect and dispose only the ice that has deteriorated in quality, thereby reducing the need for customers to take out the ice that has deteriorated in quality. This has the advantage that it can be reduced.
