In addition, the pressing unit 165a may be in close contact with the control box 150, and a force F2 having a predetermined magnitude may be applied to the control box 150.

Then, in the control box 150, a reaction force of the same magnitude as the force (F2) is applied toward the pressing portion (165a). Accordingly, the seating portion 164 may be prevented from sagging downward by the force (F2), the cooling core 143 and the heat transfer fin 147 may also be prevented from sagging.

That is, since the first departure preventing unit 165 is supported by the control box 150, sagging of the cooling core 143 may be prevented.

9 is a perspective view of an ice maker showing a departure prevention unit according to a second embodiment of the present invention, Figure 10 is a view showing a state that the lifting of the cooling core is prevented by the departure prevention unit according to a second embodiment of the present invention. .

9 and 10, the ice maker 140 according to the second embodiment of the present invention includes a second departure preventing part 265 to prevent the cooling core 143 from being lifted up.

In detail, the second departure preventing part 265 extends outward from at least one side end of the seating part 164 and is bent upward. In addition, one side surface of the second departure preventing part 265 is located in close proximity to the control box 150 and is closely attached to the control box 150 when the seating part 164 is lifted. The pressing unit 265a is formed to transmit a predetermined force.

In addition, a scratch preventing member 269 is provided at one side of the second departure preventing part 265 to prevent scratching between the second departure preventing part 265 and the control box 150. Here, the scratch preventing member 269 is maintained in contact with the control box 150 to the extent that the second departure preventing part 265 is moved in the vertical direction but is not interfered by the control box 150. Can be.

On the other hand, foreign matters 182, such as debris of ice iced while the seating portion 164 and the cooling core 143 are moved in the vertical direction or rotated in a predetermined direction, are seated with the ice tray 146. It may be caught between the portions 164.

In this case, ice ice is completed, and the cooling core 143 and the seating portion 164 return to an initial position, that is, a position where the ends of the cooling core 143 are accommodated in the ice tray 146. In the seating portion 164 may not be smoothly returned to the initial position, a predetermined force (F3) acting upward by the foreign matter 182 may be applied.

The force F3 is transmitted in the direction B by the second departure preventing part 265, and the pressing part 265a is in close contact with the control box 150 to transmit a predetermined force. Then, in the control box 150, the force of the same magnitude as the force transmitted from the pressing unit 265a, that is, the reaction force (F4) is acted toward the pressing unit 265a.

By the reaction force (F4), a force formed downward from one side of the seating portion 164 may be applied. Then, the foreign matter 182 may be removed, and the seating portion 164 and the cooling core 143 may be returned to the initial position.

That is, the second departure preventing unit 265 is supported by the control box 150, so that the lifting of the cooling core 143 may be prevented.

FIG. 11 is a view illustrating a deflection and lifting of a cooling core by a departure prevention part according to a third exemplary embodiment of the present invention.

The ice maker 140 according to the third embodiment of the present invention includes a third departure preventing part 365 to prevent sagging and lifting of the cooling core 143.

In detail, the third departure preventing part 365 extends upwardly and downwardly from the seating part 164. The first pressing part 365a which is in close contact with the control box 150 when the deflection of the cooling core 143 occurs in one lower portion of the third departure preventing part 365, provides a pressing force, When lifting of the cooling core 143 occurs, a second pressing part 365b is provided in close contact with the control box 150 to provide a pressing force.

The first pressing part 365a and the second pressing part 365b are provided with a scratch preventing member 369 to prevent scratching between the third departure preventing part 365 and the control box 150.

The operation of the third departure prevention unit 365 will be described.

First, when a downward deflection stress F5 is generated at one end of the cooling core 143, the deflection stress F5 is transmitted in the C direction. In addition, the first pressing part 365a is in close contact with the control box 150 and transmits a predetermined force by the force F5, and the first pressing part 365a is applied to the control box 150. Reaction force (F6) is acting on.

Then, since upward force is applied to one end of the cooling core 143, the sag does not occur in the cooling core 143.

Next, when lifting stress F7 is generated at one end of the cooling core 143 downward, the lifting stress F7 is transmitted in the D direction. In addition, by the force F7, the second pressing part 365b is in close contact with the control box 150 to transmit a predetermined force, and in the control box 150, the second pressing part 365b. Reaction force (F8) is acted on.

Then, since a downward force is applied to one end of the cooling core 143, foreign matter can be removed.

By the configuration as described above, there is an advantage that the ice ribbing process can be easily made by the sagging and lifting does not occur in the process of moving the cooling core 143 and the seating portion 164.

Another embodiment is proposed.

In the above-described embodiment, the case in which the seating portion 164 and the cooling core 143 are vertically moved and rotated has been described. However, in the state where the seating portion 164 and the cooling core 143 are fixed, The ice tray 146 may be vertically moved and rotated.

In this case, the seating portion 164 is connected to the ice tray 164. In addition, the same process as the above-described embodiment may be applied to the process of transmitting the driving force generated in the control box 150 to the seating part 164.

That is, when the seating portion 164 is vertically moved and rotated, the ice tray 146 may be moved in the same direction as the seating portion 164.

On the other hand, in order to prevent the deflection downward from one side end of the ice tray 146 may be provided a departure prevention portion that is bent downward from the seating portion 164.

In addition, since the detachment preventing part is provided in the ice tray 146, interference between the ice tray and the ice tray 146 occurs due to the sag of the ice tray 146, and thus, the ice separation may be prevented from failing. There is an advantage that it can.

In addition, when the ice tray 146 is returned to the initial position while the ice tray 146 is vertically moved, the return position of the ice tray 146 may be prevented from being changed due to the deflection of the ice tray 146. .
