The first ice I1 separated from the first tray unit 410 may fall onto the first guide 710. The first ice (I1) may be moved to the first storage space (132) by the first guide (710).

The second ice I2 separated from the second tray unit 450 may fall onto the second guide 730. The second ice I2 may be moved to the second storage space 134 by the second guide 730.

The upper end of the ice bin 14 may be positioned adjacent to the lower end of the second guide 730 so that the second ice I2 is moved to the second storage space 134.

The ice making device 1 may further include a partition plate 80 to prevent the first ice and the second ice falling on the guide 70 from mixing. The partition plate 80 extends in the vertical direction and may be coupled to the guide 70 or the ice making unit 40.

This is a diagram showing how water is supplied to the second ice-making cell. Figure 20 is a diagram showing the positional relationship between the lower supporter and the guide during the moving process.

Referring to FIGS. 1 to 20, the process of generating ice in the ice making device 1 will be described.

The process for producing ice may include a watering process. The process for generating ice may further include an ice-making process. The process for generating ice may further include a moving process.

When the water supply process begins, the water supply valve 304 is turned on and water supplied from the external water supply source 302 flows along the water supply passage. The water flowing along the water supply passage is supplied to the ice-making unit 40 through the water supply mechanism 320.

The water supplied to the ice making unit 40 falls to the lower side of the ice making unit 40 and is stored in the water storage unit 350. When the level of water stored in the water storage unit 350 reaches the reference level, the water supply valve 304 is turned off and the water supply process is completed.

After the water supply process is completed, the ice making process begins.

In the ice-making process, water is supplied to the ice-making unit 40 by the water supply unit 330. Additionally, during the ice-making process, the cooling unit operates and low-temperature refrigerant may flow into the cooler 50.

In the ice-making process of this embodiment, while water is supplied to each ice-making cell (440, 451), a portion of the supplied water undergoes a phase change into ice, and the size of the phase-changed ice increases, creating ice.

When the ice making process starts, one or more of the first and second pumps 360 and 362 may operate.

When the first pump 360 operates, water may be supplied to the first tray unit 410 through the first water supply unit 380.

The first water nozzle 381 is located below the first tray unit 410. Water sprayed upward from the first water nozzle 381 is supplied to the first ice making cell 440 of the first tray unit 410.

Water sprayed upward from the first water nozzle 381 is supplied to the first ice making cell 440 through the first lower opening 423 of the lower tray body 420. The water supplied to the first ice making cell 440 flows toward the upper surface of the upper tray body 430.

Water sprayed upward from the first water nozzle 381 may be supplied to a plurality of first ice making cells 440. Although not limited, water sprayed from one first water nozzle 381 may be supplied to four first ice making cells 440.

Some of the water in the first ice-making cell 440 may be frozen by the first refrigerant pipe 510. Unfrozen water falls downward again through the first lower opening 423. The water that falls downward through the first lower opening 423 is stored in the water storage unit 350 again.

During the ice-making process, ice is generated on the upper side of the first ice-making cell 440 and grows downward. As water is sprayed into the first ice-making cell 440, a portion of the water is frozen. In the process of spraying the water onto the upper tray body 420 or the ice generated in the upper tray body 420, air bubbles in the water become water. can be discharged from When air bubbles in the water are expelled from the water, the transparency of the ice produced can be increased.

During the ice-making process, the first ice I1 may grow to the inside of the first lower cell 442.

When the second pump 362 operates, water may be supplied to the second tray unit 450 through the second water supply unit 382.

The second water nozzle 383 may be located below the second tray unit 450. Water sprayed upward from the second water nozzle 383 is supplied to the second ice making cell 451 of the second tray unit 450.

The water sprayed upward from the second water nozzle 383 is used to make the second ice through the supporter opening 482a of the lower supporter 480 and the second lower opening 473 of the lower tray 470. It may be supplied to the cell 451.

As described above, water sprayed from one second water nozzle 383 may be directly supplied to one second ice making cell 451.

Accordingly, the through hole for discharging water formed in the second water nozzle 383 may be aligned with the supporter opening 482a and the second lower opening 473 in the vertical direction.

The water supplied to the second ice making cell 451 flows toward the inner upper surface of the upper tray 460. Some of the water in the second ice-making cell 451 may be frozen by the second refrigerant pipe 520. Unfrozen water again falls downward through the second lower opening 473. The water that falls downward through the second lower opening 473 is stored in the water storage unit 350 again.

As water is sprayed into the second ice-making cell 451, a portion of the water is frozen. In the process of spraying the water onto the upper tray 460 or ice generated in the upper tray 460, air bubbles in the water are discharged from the water. It can be. When air bubbles in the water are expelled from the water, the transparency of the ice produced can be increased.

The transparency of the first ice (I1) generated in the first ice-making cell 440 and the transparency of the second ice (I2) generated in the second ice-making cell 451 may be different.

During the ice-making process, the second ice I2 may grow from the upper tray 460 side to cover the upper side of the second lower opening 423a of the lower tray 470.

Once the de-icing process is completed, the de-icing process is performed. The ice-making process may be determined to be completed when the temperature detected by the temperature sensor for detecting the temperature of each tray unit reaches the end reference temperature.

When the moving process begins, the flow direction of the refrigerant is switched by the valve so that the high-temperature refrigerant compressed in the compressor 183 can flow to the cooler 50. The high-temperature refrigerant flowing into the cooler 50 may exchange heat with the ice-making unit 40. When high-temperature refrigerant flows into the cooler 50, heat may be transferred to the ice-making unit 40.

The first ice I1 may be separated from the first tray unit 410 by the heat transferred to the ice making unit 40. When the first ice (I1) is separated from the first tray unit (410), the first ice (I1) may fall onto the guide (70). The first ice I1 that fell to the guide 70 may be stored in the first storage space 132.

The second ice I2 may be separated from at least the upper tray 460 by the heat transferred to the ice making unit 40.

As time passes, or when the temperature of each tray unit reaches a set temperature, the flow of high-temperature refrigerant to the cooler 50 may be blocked.

Next, the driving unit 690 may operate to separate the second ice I2 from the second tray unit 450. By operating the driving unit 690, the lower tray 470 can be rotated in the forward direction (clockwise with respect to FIG. 17).

When the second ice (I2) is separated from the upper tray 460 and the lower tray 470 by the high-temperature refrigerant flowing into the cooler 50, the second ice (I2) is The lower tray 470 may be rotated while supported on the lower tray 470 . In this case, when the lower tray 470 rotates approximately 90 degrees, the second ice I2 may fall from the lower tray 470.

On the other hand, when the second ice (I2) has been separated from the upper tray 460 but has not yet been separated from the lower tray 470 by the high-temperature refrigerant flowing into the cooler 50, the second ice I2 is separated from the lower tray 470. As the pusher 490 presses the lower tray 470 while the 470 is rotated by the moving angle, the second ice I2 may be separated from the lower tray 470 and fall.

When the second ice I2 is separated from the second tray unit 450, the second ice I2 may fall onto the guide 70. The second ice I2 that fell to the guide 70 may be stored in the second storage space 134.

During the moving process, the lower supporter 480 is rotated in a direction closer to the guide 70. Since the lower supporter 480 is provided with an inclined surface 481d, the lower supporter 480 and the guide 70 ) interference can be prevented.

After the lower tray 470 is rotated in the forward direction, the lower tray 470 is rotated in the reverse direction (counterclockwise in the drawing) by the driving unit 690 to contact the upper tray 460. You can.

When the moving process is performed once or a set number of times, the water in the water storage unit 350 may be discharged to the outside through the drain pipe 390 and the drain tube 392 (drain process). That is, the drain valve can be turned on for a certain period of time when the water drain condition is satisfied.

The next water supply process can be started after the drain process is performed. When the drain process is performed intermittently, if the drain condition is not satisfied, the water supply process may be performed immediately after the moving process is performed. When the drain condition is satisfied, the drain process may be performed after the moving process, and the water supply process may be performed after the drain process is completed.

Figure 28 is a diagram showing a process in which water is supplied to the ice-making unit during the ice-making process according to the second embodiment.

Referring to FIG. 28, the process for creating ice in this embodiment may include a water supply process. The process for generating ice may further include an ice-making process. The process for generating ice may further include a moving process.

When the water supply process begins, the water supply valve 304 is turned on and water supplied from the external water supply source 302 flows along the water supply passage. The water flowing along the water supply passage is supplied to the ice-making unit 40 through the water supply mechanism 320.

The water supplied to the ice making unit 40 falls to the lower side of the ice making unit 40 and is stored in the water storage unit 350. When the level of water stored in the water storage unit 350 reaches the reference level, the water supply valve 304 is turned off and the water supply process is completed.

After the water supply process is completed, the ice making process begins.

In the ice making process, the pumps 360 and 362 may be turned on simultaneously or sequentially.

For example, when the first pump 360 operates, water may be supplied to the first tray unit 410 through the first water supply unit 380.

Water sprayed upward from the first water supply unit 380 may be supplied to the first ice-making cell 440 through the first lower opening 423 of the lower tray body 420.

When the second pump 362 operates, water may be supplied to the second tray unit 450 through the second water supply unit 382.

The water sprayed upward from the second water supply unit 1382 is used to make the second ice through the supporter opening 482a of the lower supporter 480a and the second lower opening 473 of the lower tray 470. It may be supplied to the cell 451.

In this embodiment, since the second water supply unit 1382 is mounted on the lower supporter 480a, water can be intensively supplied to the second ice-making cell 451.

Once the ice making process is completed, the ice removal process may be performed.

When the moving process begins, the high-temperature refrigerant compressed in the compressor 183 may flow into the cooler 50. The high-temperature refrigerant flowing into the cooler 50 may exchange heat with the ice-making unit 40. When high-temperature refrigerant flows into the cooler 50, heat may be transferred to the ice-making unit 40.

The first ice I1 may be separated from the first tray unit 410 by the heat transferred to the ice making unit 40. When the first ice (I1) is separated from the first tray unit (410), the first ice (I1) may fall onto the guide (70).

The second ice I2 may be separated from at least the surface of the upper tray 460 by the heat transferred to the ice making unit 40. As time passes, or when the temperature of each tray unit reaches a set temperature, the flow of high-temperature refrigerant to the cooler 50 may be blocked.

Next, the driving unit 690 may operate to separate the second ice I2 from the second tray unit 450.

That is, after the creation of the second ice in the second ice making cell 251 is completed, the controller moves the lower tray 470 to the first moving position in order to take out the ice in the second ice making cell 251. After moving in one direction (clockwise based on FIG. 28), it can be controlled to move in a second direction.

As the pusher 490a presses the lower tray 470 while the lower tray 470 is rotated to the moving position, the second ice I2 may be separated from the lower tray 470 and fall. .

Alternatively, depending on the size of the second lower opening 473, it is possible for the pusher 490a to directly press the second ice I2 through the lower tray 470. Alternatively, it is also possible for the pusher 490a to contact the lower tray 480 and the second ice I2.

During the moving process, the second water supply unit 1382 may move in a direction closer to the pusher 490a.

As described above, since the pusher 490a includes the path 393, the second water supply unit 1382 can be moved without interfering with the pusher 490a during the moving process. For example, the supply pipe 1386 may be moved while accommodated in the pushing bar 492.

After the lower tray 470 is rotated in the first direction, the lower tray 470 is rotated in the second direction (counterclockwise in the drawing) by the driving unit 690 to form the upper tray 460 and the upper tray 460. can be contacted.
