[0142] The above bracket (220) may include two second walls (222) extending in one direction (e.g., downward) from both sides of the first wall (221). The space between the two second walls (222) may form a space in which a tray assembly is placed.

[0143] A driving unit (510) may be arranged on the outside of one of the two second walls (222). The other of the two second walls (222) functions as a preventive plate that prevents ice from falling into the ice bin (600) or ice stored in the ice bin (600) from falling, and may have a wall penetration hole (222a) formed at least partially through the wall to prevent frost formation.

[0144] The bracket (220) may include a third wall (223) protruding from the first wall (221). The third wall (223) may protrude from the first wall (221) in a direction toward the storage compartment. The third wall (223) may include a first part (223a) extending in a direction corresponding to one direction (e.g., front-back direction) of the storage compartment, and a second part (223b) extending from one end (e.g., front end) of the first part (223a) in the other direction (e.g., left-right direction). The third wall (223) may include a hook (223c) coupled to one surface (e.g., upper surface) of the storage compartment. For example, the hook (223c) may be provided on the second part (223b).

[0145] A water supply unit (240) can be coupled to the second part (223b). The water supply unit (240) includes a hook (248), and the hook (248) can be hooked to one end (e.g., the upper end) of the second part (223b).

[0146] The bracket (220) may be formed with a suction hole (224a) through which cold air from the storage chamber flows toward the tray assembly. The suction hole (224a) may be formed in a side wall of the bracket (220). For example, the suction hole (224a) may be formed in a space between the second wall (222) and the third wall (223). From another perspective, the suction hole (224a) may be formed by penetrating at least a portion of the second wall (222).

[0147] Cold can be sucked into the tray assembly side through the suction hole (224a) from the side of the bracket (220) and act as cold for ice making.

[0148] The through hole (226) of the first wall (221) may function as an outlet through which cold air passing through the tray assembly is discharged. The through hole (226) may be provided in multiple numbers and formed in a first direction (e.g., horizontal direction) of the first wall (221).

[0149] The above bracket (220) may include a guide wall (225) that guides cold sucked through the suction hole (224a) toward the tray assembly. The guide wall (225) may extend from the third wall (223) toward the central portion of the bracket (220).

[0150] The above bracket (220) may include a blocking plate (227a) that prevents cold air sucked through the suction hole (224a) from being discharged from the bracket (220) rather than toward the tray assembly. For example, the blocking plate (227a) may extend in one direction (e.g., upward) from the first wall (221).

[0151] The bracket (220) may include a stopper (250) that contacts the second tray assembly. The stopper (250) may extend in the other direction (e.g., downward) from the first wall (221) and may be positioned to contact at least a portion of the second tray assembly. The stopper (250) may have a bar shape.

[0152] The bracket (220) may include a fourth wall (224) to which a pusher (540) is coupled. The fourth wall (224) may extend in one direction (e.g., downward) from one end (e.g., rear end) of the first wall (221) and may form a wall of one side (e.g., rear) of the bracket (220).

[0153] The ice maker (200) may include a first tray assembly and a second tray assembly. The first tray assembly may include a first tray (300) and a first tray case. The second tray assembly may include a second tray (400) and a second tray case.

[0154] The above bracket (220) can define at least a portion of a space that accommodates the first tray assembly and the second tray assembly.

[0155] The bracket (220) may be arranged, for example, on one side wall (e.g., the upper wall) of the freezer (32). A water supply unit (240) may be arranged on the bracket (220). The water supply unit (240) may guide water supplied from one side (e.g., the upper side) to the other side (e.g., the lower side) of the water supply unit (240). A water supply pipe (not shown) for supplying water may be arranged on one side (e.g., the upper side) of the water supply unit (240).

[0156] The above water supply unit (240) may be supported by a bracket (220). The above water supply unit (240) may include a hook (248) that is coupled to the bracket (220). For example, the hook (248) may be hooked to a second part (223b) of the bracket (220).

[0157] The ice maker (200) may include a cell (see 360 ​​in FIG. 11), which is a space where water changes into ice due to cold. The first tray (300) may form at least a portion of the cell (360). The second tray (400) may form another portion of the cell (360). The cell (360) may include a first cell formed by the first tray (300) and a second cell formed by the second tray (400).

[0158] The first tray (300) can be coupled to a bracket (220). The second tray (400) can be positioned to be relatively movable with respect to the first tray (300). The second tray (400) can move linearly or rotate.

[0159] During the ice-making process, the second tray (400) moves relative to the first tray (300), so that the first tray (300) and the second tray (400) can come into contact. When the first tray (300) and the second tray (400) come into contact, the cell (360) can be defined.

[0160] After the ice making is completed, the second tray (400) may move relative to the first tray (300) during the ice removal process, so that the second tray (400) may be separated from the first tray (300).

[0161] The first tray (300) and the second tray (400) may be arranged in one direction (e.g., up and down) while forming the cell (360). Accordingly, the first tray (300) may be referred to as an upper tray, and the second tray (400) may be referred to as a lower tray.

[0162] A plurality of cells (360) can be defined by the first tray (300) and the second tray (400). For example, the plurality of cells (360) can include three cells (360).

[0163] When water is supplied to the cell (360) and the water is cooled by cold, ice having a shape identical to or similar to that of the cell (360) can be created. For example, the cell (360) can be formed in a spherical shape or a shape similar to a sphere. Of course, the cell (360) can also be formed in a rectangular parallelepiped shape or a polygonal shape.

[0164] The first tray (300) may include a plurality of tray parts (300a, 300b, 300c). The number of the plurality of tray parts (300a, 300b, 300c) may correspond to the number of the plurality of cells (360).

[0165] Each tray part can form at least a portion of one cell. Based on the total surface area of ​​one cell (360), the surface area of ​​a portion of the cell formed by each tray part can be smaller than the surface area of ​​another portion of the cell formed by the second tray (400).

[0166] The second tray case may include, for example, a second tray cover (480) and a second tray supporter (450). The second tray (400), the second tray supporter (450), and the second tray cover (480) may be joined by a fastening member.

[0167] At least a portion of the second tray cover (480) may be positioned on one side (e.g., the upper side) of the second tray (400). The second tray cover (480) may include a cover wall (481) forming an opening (482).

[0168] The above opening (482) may be formed so that at least a portion of the second tray cover (480) passes through it so that at least a portion of the second tray (400) passes through it. The opening (482) may be formed to have a predetermined curvature corresponding to the shape of the outer circumferential surface of the cell (360).

[0169] The above cover wall (481) may be placed on one side (e.g., the upper side) of the first extension wall (420) of the second tray (400). The first extension wall (420) may include a tray protrusion (429) that comes into contact with the second tray cover (480).

[0170] The above tray protrusion (429) extends in one direction (for example, upward) from the first extension wall (420), and a plurality of them may be provided on the corner side of the first extension wall (420).

[0171] The second tray cover (480) may include a projection receiving portion (486) that protrudes in one direction (e.g., upward) from the cover wall (481) to receive the tray projection (429). The tray projection (429) may penetrate the cover wall (481) and be inserted into the projection receiving portion (486). A projection (566) of a lift (560) may come into contact with one surface (e.g., a bottom surface) of the first extension wall (420).

[0172] The first extension wall (420) may be provided with a tray protrusion (427a) provided on both sides of the tray wall of the second tray (400). The tray protrusion (427a) may protrude in one direction (e.g., upward) from the first extension wall (420).

[0173] The second tray cover (480) is formed to penetrate the cover wall (481), and a guide hole (481b) for receiving the tray protrusion (427a) can be formed. The assembly of the second tray (400) and the second tray cover (480) can be guided through the guide hole (481b).

[0174] The second tray cover (480) may include a cover fastening portion (485) that protrudes in one direction (e.g., downward) from the cover wall (481). A plurality of the cover fastening portions (485) are provided along the perimeter of one side (e.g., the bottom side) of the cover wall (481), and may be coupled to at least one of the fastening portion (425) of the second tray (400) and the supporter fastening portion (456) of the second tray supporter (450). In a state where the cover fastening portion (485) is coupled to the fastening portion (425) and the supporter fastening portion (456), a fastening member may be coupled to one side (e.g., the lower side) of the second tray supporter (450).

[0175] The second tray cover (480) is provided on the cover wall (481) and may include a moving guide (487) that helps move ice during the moving process.

[0176] The above-mentioned moving guide (487) may be provided on a portion (e.g., a rear portion) of the cover wall (481). For example, the moving guide (487) may be positioned adjacent to the axis of the shaft (520). The moving guide (487) may have a groove (487a) surrounding at least a portion of the shaft (520). The groove (487a) may be referred to as a first part.

[0177] During the moving process, the second tray cover (480) can move. For example, the second tray cover (480) can rotate.

[0178] During the movement of the second tray cover (480), the distance by which the moving guide (487) moves may be shorter than the distance by which the front of the second tray cover (480a) moves. The moving guide (487) may be provided in multiple numbers corresponding to the number of cells (360).

[0179] The above-mentioned moving guide (487) can pressurize the ice attached to the first tray (300) during the moving process to separate the ice from the first tray (300).

[0180] The above-mentioned moving guide (487) can function to remove ice residue attached to the first tray (300) or ice residue existing in the contact area between the first tray (300) and the second tray (400) during the moving process. The above-mentioned moving guide (487) can be called a “movable pusher” or a “first pusher.”

[0181] At least a portion of the second tray supporter (450) may be positioned on one side (e.g., the lower side) of the second tray (400). The second tray supporter (450) may support the second tray (400) on one side (e.g., the lower side) of the second tray (400). For example, at least a portion of a wall forming a second cell of the second tray (400) may be supported by the second tray supporter (450).

[0182] The second tray supporter (450) may include two first walls (451) forming two side surfaces. The two extensions (455) may be provided at one end (e.g., the rear end) of the first wall (451), respectively.

[0183] The second tray supporter (450) may include a second wall (452) connecting the other ends (e.g., front ends) of the two first walls (451). The second wall (452) may form one side (e.g., front end) of the second tray supporter (450).

[0184] The second tray supporter (450) may include a third wall (453) forming the other surface (e.g., the upper surface) of the second tray supporter (450). The first extension wall (420) of the second tray (400) may be mounted on the third wall (453). A first joining portion (459a) to which a first edge (422a, see FIG. 11) of the second tray (400) is joined may be formed on the third wall (453).

[0185] A second joining portion (459b) to which a protrusion (422c, see FIG. 11) of the second tray (400) is joined may be formed on the third wall (453). An insertion portion (458a) to which a second edge (422b, see FIG. 11) of the second tray (400) is joined may be formed on the third wall (453). The insertion portion (458a) may include a recess recessed from the third wall (453) so that the second edge (422b) is inserted.

[0186] The second tray supporter (450) may include at least one of a fourth wall (454) and a fifth wall (458) extending in one direction (e.g., downward) from the third wall (453). The fourth wall (454) may be understood as one wall (e.g., a rear wall) of the second tray supporter (450), and the fifth wall (458) may be understood as another wall (e.g., an inner wall) spaced apart in one direction (e.g., forward) from the fourth wall (454). The insertion portion (458a) may be a space formed between the fourth wall (454) and the fifth wall (458).

[0187] The extension portion (455) of the second tray cover (450) may include two extension portions (455) forming a through hole (455a) into which a holder (531, 532) is inserted.

[0188] The ice maker (200) may include a pusher (540). The pusher (540) may be coupled to the bracket (220), for example. The pusher (540) may be referred to as a "fixed pusher" or a "second pusher." The number of pushers (540) may be the same as the number of cells (360), but is not limited thereto.

[0189] The pusher (540) can push out ice located in the cell (360). For example, the pusher (540) can penetrate the second tray supporter (450) and come into contact with the second tray (400) forming the cell (360), and pressurize the second tray (400) that has come into contact with it.

[0190] The above ice maker (200) may include a heater (490, 495).

[0191] The above heater (490, 495) is disposed in the sunken receiving space (453a) of the second tray supporter (450) and may include a first heater (490) for applying heat to the second tray (400) during the ice-making process. The first heater (490) may be disposed adjacent to or in contact with one side (e.g., the lower side) of the second tray (400) so as to supply heat to a portion (e.g., the lower side) of the second tray (400).

[0192] The first heater (490) may be operable to assist in creating ice or transparent ice. The first heater (490) may be referred to as a "transparent ice heater." The first heater (490) may be, for example, a wire-type heater.

[0193] The heater (490, 495) may include a second heater (495) that is controlled to be turned on at least for a portion of the time after ice making is completed so that ice can be easily separated from the tray assembly. The second heater (495) may be positioned adjacent to the first tray (300). The second heater (495) may be, for example, a wire-type heater. The second heater (495) may be referred to as an "ice-removing heater."

[0194] The second heater (495) may be covered by the bracket (220). Therefore, the fluid discharged through the first tray (300) may be prevented from coming into contact with the second heater (495).

[0195] The bracket (220) may include a heater fixing portion (221b, see FIG. 11) for attaching the second heater (495). The heater fixing portion (221b) may protrude in one direction (e.g., downward) from a joining wall (221a, see FIG. 11) of the bracket (220). The joining wall (221a) may form a wall to which the first tray (300) is attached.

[0196] The above lift (560) can be coupled to the shaft (520) or the holder (531, 532). The lift (560) can move together with the shaft (520) and the holder (531, 532). The lift (560) can be provided in multiple units on both sides of the shaft (520).

[0197] The above lift (560) may include a support bar (561) that supports the lower portion of the second tray (400). The support bar (561) may be placed on the outer side of the side wall of the second tray supporter (450).

[0198] The above lift (560) may include an extension (563) coupled to the holder (531, 532). The extension (563) may form a through hole (564) into which the holder (531, 532) is inserted.

[0199] The above lift (560) may include a protrusion (566) protruding from the support bar (561) in a direction toward the second tray (400). The protrusion (566) may press one surface (e.g., the bottom surface) of the tray protrusion (429) of the second tray (400) to bring the second tray (400) into close contact with the first tray (300).

[0200] At the ice-making position of the tray assembly, the lift (560) can move further in one direction (for example, upward) based on the axis of the shaft (520) so that the second tray (400) is brought into close contact with the first tray (300).

[0201] The second tray cover (480) may include a protrusion receiving portion (486) into which the tray protrusion (429) is inserted. One surface (e.g., the upper surface) of the protrusion receiving portion (486) may be supported by the stopper (250).

[0202] The ice maker (200) may include a driving unit (510) that provides driving force. The second tray (400) may receive driving force from the driving unit (510) and move relative to the first tray (300). The driving unit (510) may include a driving motor.

[0203] The ice maker (200) may include a shaft (520) that passes through the through hole (455a) of the second tray supporter (450). The shaft (520) extends between the two extensions (455) and may be moved by receiving power from the driving unit (510).

[0204] The above driving unit (510) may include a motor and a plurality of gears.

[0205] A full ice detection lever (550) may be connected to the driving unit (510). The full ice detection lever (550) is moved by power provided from the driving unit (510), and can detect ice stored in the ice bin (600) during the movement process.

[0206] The above driving unit (510) may include a cam that moves or rotates by receiving the moving power of the motor. The ice maker (200) may include a sensor that detects the movement or rotation of the cam.

[0207] The refrigerator controller can determine the position of the second tray (400) (or second tray assembly) based on the type and pattern of the signal output from the sensor. That is, since the second tray (400) and the cam are moved by the motor, the water supply position, ice-making position, and ice-separating position of the second tray (400) can be distinguished and determined based on the detection signal of the magnet provided in the cam.

[0208] The second tray (400) may be formed of a non-metallic material. For example, the second tray (400) may be formed of a flexible or malleable material that can be deformed when pressed by the pusher (540). Although not limited, the second tray (400) may be formed of a silicone material, for example.

[0209] In the process of pressurizing the second tray (400) by the pusher (540), the second tray (400) may be deformed and the pressing force of the pusher (540) may be transmitted to the ice. The ice and the second tray (400) may be separated by the pressing force of the pusher (540).

[0210] When the second tray (400) is formed of a non-metallic material and a flexible or malleable material, the bonding or adhesive force between the ice and the second tray (400) may be reduced, so that the ice may be easily separated from the second tray (400).

[0211] When the second tray (400) is formed of a non-metallic material and a flexible or malleable material, after the shape of the second tray (400) is deformed by the pusher (540), when the pressing force of the pusher (540) is removed, the second tray (400) can be restored to its original shape.

[0212] For example, the first tray (300) may be formed of a metal material or a plastic material. In this case, the bonding or adhesive force per unit area between the first tray (300) and the ice may be relatively strong. However, since the first cell formed within the first tray (300) has a small surface area (or ice contact area), ice separation can be easily achieved.

[0213] As another example, the first tray (300) may be formed of a non-metallic material. In this case, the bonding or adhesive force per unit area between the first tray (300) and the ice may be relatively weak. Accordingly, ice separation may be facilitated. Although not limited, the first tray (300) may be formed of, for example, a silicone material.

[0214] The first tray (300) and the second tray (400) may be formed of the same material. In this case, the hardness of the first tray (300) and the hardness of the second tray (400) may be different so that sealing performance is maintained at the contact area between the first tray (300) and the second tray (400).

[0215] In the present embodiment, since the second tray (400) is pressed by the pusher (540) and is deformed, the hardness of the second tray (400) may be lower than the hardness of the first tray (300) so that the shape of the second tray (400) can be easily deformed.

[0216] FIG. 4 is a plan view showing the configuration of the first and second tray assemblies and the power transmission device according to the first embodiment of the present invention, FIG. 5 is a perspective view of the first tray according to the first embodiment of the present invention, FIG. 6 is a cross-sectional view taken along line 6-6 of FIG. 5, and FIG. 7 is an exploded perspective view showing the configuration of the second tray assembly and the power transmission device according to the first embodiment of the present invention.

[0217] Referring to FIGS. 4 to 7, a first tray (300) according to an embodiment of the present invention may include a plurality of tray parts (300a, 300b, 300c). The number of the plurality of tray parts (300a, 300b, 300c) may correspond to the number of the plurality of cells (360).

[0218] The above multiple tray parts (300a, 300b, 300c) can be arranged in a row in one direction (e.g., X-axis direction). The first tray (300) can form an upper tray.

[0219] The first tray (300) may include a first tray wall (310) forming a part of the cell (360). For example, the first tray wall (310) may define the first cell (30b).

[0220] The first tray wall (310) may include a first cell wall (311) defining a first cell surface (310a). The inner surface of the first cell wall (611) forms the first cell surface (310a), and the first cell surface (310a) may be understood to define an outer surface of the first cell (310b).

[0221] The first tray wall (310) may include a first opening (310c). The first opening (310c) forms an end (e.g., a lower end) of the first tray wall (310) and may be in contact with the second tray (400).

[0222] An edge (e.g., a lower edge) of the first tray wall (310) may form a contact end (319) that contacts the second tray (400). The second tray (400) may form a contact end (412a, see FIG. 15) that contacts the contact portion (319). The contact end (412a) may form a fore-end (e.g., an upper edge) of the second part (412) of the second tray (400). The contact end (319) of the first tray (300) may be referred to as a “first contact end”, and the contact end (412a) of the second tray (400) may be referred to as a “second contact end”.

[0223] The first tray wall (310) may include a first extension wall (313) extending in one direction (e.g., upward) from a portion of the perimeter of the first cell wall (311). For example, the first extension wall (313) may constitute at least one wall among a portion of the wall (e.g., a front wall) and another portion of the wall (e.g., a side wall) of the first tray (300).

[0224] The first tray wall (310) may include a second extension wall (314) extending in one direction (e.g., upward) from another portion of the perimeter of the first cell wall (311). For example, the second extension wall (314) may constitute a portion of a wall (e.g., a rear wall) of the first tray (300). The second extension wall (314) may be located on the inner side of the perimeter wall (430) of the second tray (400), particularly the second extension wall (431).

[0225] At the ice-making position of the above tray assembly, one end (e.g., the upper end) of the second extension wall (314) of the first tray (300) may be positioned higher than one end (e.g., the upper end) of the second extension wall (431) of the second tray (400).

[0226] In the relative positional relationship between the second extension wall (314) of the first tray (300) and the second extension wall (431) of the second tray (400), the gap between the second extension wall (314) and the second extension wall (431) may increase in one direction (for example, upward). According to this configuration, when the second tray (400) moves forward from the ice-making position to the ice-separating position or when it moves backward from the ice-separating position to the ice-making position, the phenomenon of interference with the first tray (600) can be prevented.

[0227] The first tray (300) may include a guide wall (315) extending from the first tray wall (310). The guide wall (315) may extend in a direction toward the bracket (220).

[0228] The above guide wall (315) can form a through hole (315a). The through hole (315a) can be formed to penetrate from the first cell surface (310a) of the first tray wall (310) to the outer surface of the guide wall (315). During the ice-making process, air bubbles in the cell (360) are discharged through the through hole (315a), thereby preventing an air pocket phenomenon in the cell (360).

[0229] The above guide wall (315) may include a drainage portion (315b) that is connected to the through hole (315a) and penetrates one side (e.g., the front) of the guide wall (315). The drainage portion (315b) may direct the fluid discharged through the through hole (315a) to the outside of the first tray (300), thereby preventing ice from forming in the through hole (315a). For example, the drainage portion (315b) may include a drainage hole.

[0230] One side (e.g., bottom side) of the above drainage portion (315b) may include an inclined surface (315c) extending in an inclined direction toward the side of the through hole (315a).

[0236] The first tray (300) may include a recessed joining groove (313a) at one end (e.g., the top) of the first extension wall (313). The joining groove (313a) may be joined to the bracket (220) to guide the assembly of the first tray (300) and the bracket (220).

[0237] A second tray (400) is arranged on one side (e.g., the lower side) of the first tray (300). The second tray (400) and the first tray (300) may together form a cell (360). The second tray (400) may define a second cell that is part of the cell (360).

[0238] The second tray (400) may include a plurality of tray parts (401a, 401b, 401c) corresponding to the plurality of tray parts (300a, 300b, 300c) of the first tray (300).

[0239] The second tray (400) may form each tray part (401a, 401b, 401c) and may include a second tray wall (410) defining the second cell. The second tray walls (410) are provided in multiple numbers to define multiple second cells, and the multiple second tray walls (410) may be arranged in one direction (e.g., in the X-axis direction).

[0240] The second tray (400) may include a second opening (413). The second opening (413) forms an end (e.g., an upper end) of the second tray (400) and may contact the first tray (300). The second tray (400) may include a first extension wall (420) extending in a first direction (e.g., a horizontal direction) toward the outside of the second tray wall (410). The first extension wall (420) may be mounted on a third wall (453) of the second tray supporter (450).

[0241] The second tray wall (410) may include a first part (411) positioned on one side (e.g., lower side) of the first extension wall (420) based on the first extension wall (420). The first part (411) may form one area (e.g., lower area) of the cell (360). The first part (411) may be accommodated in the accommodation space (453a) of the second tray supporter (450) and supported by the second tray supporter (450).

[0242] The second tray wall (410) may include a second part (412) positioned on one side (e.g., upper side) of the first extension wall (420) with respect to the first extension wall (420). The second part (412) may form a part of another region (e.g., upper region) of the cell (360). An end (e.g., upper end) of the second part (412) may form the second opening (413).

[0243] The second part (412) may be provided with reinforcing ribs (436) for reinforcing strength. The reinforcing ribs (436) may extend in one direction (e.g., the Z-axis direction) and may be arranged in multiple numbers in another direction (e.g., the circumferential direction) of the second part (412).

[0244] The second tray (400) may include a peripheral wall (430) extending along the perimeter of an end (e.g., an upper end) of the second tray wall (410). For example, the peripheral wall (430) may be formed integrally with the second tray wall (410) and may extend in one direction (e.g., upward) from one end (e.g., an upper end) of the second tray wall (410).

[0245] The above-mentioned peripheral wall (430) may include a second extension wall (431) extending in one direction (e.g., upward) from the second part (412). The second tray (400) may include a separating wall (432) provided between the plurality of second extension walls (431). A plurality of the separating walls (432) may be provided.

[0246] The second tray (400) may include a third extension wall (1433) that guides the fluid supplied from the water supply unit (240) to the cell (360). The third extension wall (1433) may include a first wall part (1434) that extends in the direction in which the plurality of tray parts (401a, 401b, 401c) are arranged.

[0247] The third extension wall (1433) may include a second wall part (1435) extending from both ends of the first wall part (1434) and connected to the second extension wall (431) of the second tray (400).

[0248] A power transmission device may be placed on one side (e.g., the rear side) of the second tray (400) and the second tray cover (480).

[0249] The power transmission device may include a shaft (520) that is connected to and moves the driving unit (510). The shaft (520) may extend in a direction in which a plurality of tray parts (300a, 300b, 300c) of the first tray (300) are arranged or in a direction in which a plurality of tray parts (401a, 401b, 401c) of the second tray (400) are arranged.

[0250] The power transmission device may include a holder (530) provided at an end of the shaft (520) to transmit the power of the driving unit (510) to the shaft (520).

[0251] The holder (530) may include a first holder (531) that is axially coupled to the driving unit (510) as a driving holder. The first holder (531) may be coupled to a first end of the shaft (520). An insertion hole (521) into which the first holder (531) is inserted may be formed in the first end of the shaft (520).

[0252] An insertion hole (521) into which a second holder (532) is inserted may also be formed at the second end of the shaft (520), that is, at the end opposite the first end. The first holder (531) is coupled to the motor shaft of the driving unit (531) and extends in a direction toward the shaft (520), and may pass through the first through hole (564) of the lift (560) and the second through hole (455a) of the second tray supporter (450) to be coupled to the insertion hole (521) of the shaft (520).

[0253] The first holder (531) may include an insertion bar (531a) coupled to an insertion hole (521) of a first end of the shaft (520). The first holder (531) may include a protrusion (531b) protruding from an outer surface of the insertion bar (531a). An end of the protrusion (531b) may be supported by an end of the shaft (520). A plurality of the protrusions (531b) may be provided so as to protrude from both sides of the outer surface of the insertion bar (531a).

[0254] At least a portion of the above insertion bar (531a) and the above protrusion (531b) can be inserted into the first through hole (564) of the lift (560).

[0255] The holder (530) may include a second holder (532) coupled to the second end of the shaft (520) as a driven holder. The second holder (532) may be coupled to an insertion hole (521) formed in the second end of the shaft (520).

[0256] The second holder (532) above is different from the first holder (531) only in that the motor shaft of the driving unit (510) is not coupled, and the structure of being coupled to the insertion hole (521) of the shaft (520) by penetrating the first through-hole (564) of the lift (560) and the second through-hole (455a) of the second tray cover (450) is the same as the first holder (531).

[0257] FIG. 8 is a perspective view showing the configuration of a second tray cover according to the first embodiment of the present invention, FIG. 9 is a cross-sectional view taken along line 9-9 of FIG. 8, and FIG. 10 is a drawing showing ice formed in the second tray assembly according to the first embodiment of the present invention.

[0258] Referring to FIGS. 8 to 10, the second tray cover (480) according to the first embodiment of the present invention may include a cover wall (481) forming an opening (482) into which a portion of the second tray (400) is inserted.

[0259] The second tray cover (480) may include a moving guide (487) provided on the cover wall (481). The moving guide (487) may be provided to contact the ice for moving the manufactured ice. As another example, the moving guide (487) may be provided to remove any remaining ice present on or around the surface of the tray assembly.

[0260] The above-mentioned moving guide (487) may be provided on the edge side of the cover wall (481). For example, the above-mentioned moving guide (487) may be placed on the edge side of a part (e.g., the rear) of the second tray cover (480) on which the shaft (520) is placed.

[0261] Defines the direction. In the tray assembly, the portion where the shaft (520) is located can be understood as the rear portion, and the portion opposite the rear portion can be understood as the front portion. Accordingly, when the shaft (520) rotates, the front portion of the second tray (400) can be understood to move downward around the shaft (520).

[0262] The above moving guides (487) may be provided in multiple numbers. The multiple moving guides (487) may be arranged in one direction (e.g., X-axis direction) in which the multiple cells (360) are arranged, corresponding to the multiple cells (360). That is, the multiple moving guides (487) may be arranged in the X-axis direction in which the multiple tray parts (401a, 401b, 401c) are arranged.

[0263] The plurality of ice guides (487) may be connected to each other by guide connecting portions (488). The guide connecting portions (488) may extend in a round shape to surround at least a portion of the outer circumference of the shaft (520). For example, the guide connecting portions (488) may include a connection bar. Each ice guide (487) is provided to be movable for separating ice generated in the plurality of cells (360), and the ice guides (487) may come into contact with the ice while moving.

[0264] The moving guide (487) can move along the surface of the first tray (300) during the moving process. For example, the moving guide (487) can move along the surface shape of the first tray (300) while in contact with the surface of the first tray (300) or adjacent to the surface of the first tray (300).

[0265] The above-mentioned moving guide (487) may have a groove (487a) surrounding at least a portion of the shaft (520). The groove (487a) is formed at an end (e.g., a lower end) of the moving guide (487) and may be formed to have a round shape with a predetermined curvature corresponding to the curvature of the outer circumferential surface of the shaft (520). The groove (487a) may be understood as a portion connected to the guide connecting portion (488) and connected to the shaft (520).

[0266] The above-mentioned moving guide (487) may include a tip (487b) located at the furthest point relative to the center (C2) of the shaft (520). The tip (487b) may be referred to as a second part. The above-mentioned moving guide (487) may extend upward from the groove (487a) toward the first tray (300). The tip (487b) may be formed at one end (e.g., the upper end) of the above-mentioned moving guide (487).

[0267] The above-mentioned moving guide (487) may include a contact portion (487c) that comes into contact with ice during the moving process. The contact portion (487c) may be formed at a portion extending in one direction (e.g., downward) from the tip (487b). The contact portion (487c) may be referred to as a third part. That is, the distance between the contact portion (487c) and the groove portion (487a) may be smaller than the distance between the tip (487b) and the groove portion (487a).

[0268] The above-described moving guide (487) may include a support portion (487d) connected to the cover wall (481). The support portion (487d) forms a part of one end (e.g., the lower end) of the moving guide (487) and may be connected to one surface (e.g., the upper surface) of the cover wall (481). The support portion (487d) may be referred to as a fourth part.

[0269] The above-described moving guide (487) may include a first reinforcing portion (487e) extending in one direction (e.g., downward) from the contact portion (487c). An end (e.g., a lower end) of the first reinforcing portion (487e) may be connected to the cover wall (481).

[0270] The first reinforcing member (487e) may extend inclinedly toward one side (e.g., downward). Due to the inclined configuration of the first reinforcing member (487e), the cross-sectional area of ​​the ice guide (487) may be configured to increase toward one side (e.g., downward) from the tip (487b).

[0271] The above-mentioned moving guide (487) may include a second reinforcing portion (487f) extending in one direction (e.g., downward) from an end (e.g., rear end) of the tip (487b). Since the first reinforcing portion (487e) and the second reinforcing portion (487f) are configured to extend in one direction (e.g., forward and backward) of the contact portion (487c), the width of the moving guide (487) in one direction (e.g., front and rear) can be formed to be large.

[0272] The first reinforcing part (487e) and the second reinforcing part (487f) may be referred to as the fifth part and the sixth part, respectively. Accordingly, the ice guide (487) can be prevented from being damaged by pressure or impact generated when the ice guide (487) comes into contact with ice or ice floes.

[0273] Each moving guide (487) may include at least one rib. The groove (487a), tip (487b), contact portion (487c), support portion (487d), and first and second reinforcing portions (487e, 487f) described above may be formed on the rib.

[0274] The above rib may include a plurality of ribs. The plurality of ribs may include a first rib (4871) positioned near the center of the cell (360). During the process of moving the ice guide (487), the first rib (4871) may come into contact with the central surface of the ice.

[0275] The above-described plurality of ribs may include a second rib (4872) spaced apart from one side of the first rib (4871). The second rib (4872) may be positioned at a position spaced apart from the center of the cell (360) in the circumferential direction to one side. In the process of moving the ice guide (487), the second rib (4872) may come into contact with a surface spaced apart from the center surface of the ice in the circumferential direction to one side.

[0276] The above-described plurality of ribs may include a third rib (4873) arranged spaced apart from the other side of the first rib (4871). The second rib (4872) may be arranged at a position spaced apart from the center of the cell (360) in the other direction in the circumferential direction. In the process of moving the ice guide (487), the third rib (4873) may come into contact with a surface spaced apart from the center surface of the ice in the other direction in the circumferential direction.

[0277] The second rib (4872) and the third rib (4873) may be arranged on both sides of the first rib (4871). The first rib (4871) may be referred to as a “center rib”, and the second and third ribs (4872, 4873) may be referred to as “side ribs”. For example, the gap between the first rib (4871) and the second rib (4872) may be the same as or substantially the same as the gap between the first rib (4871) and the third rib (4873).

[0278] The second rib (4872) may be positioned closer to the cell (360) or the opening (482) than the first rib (4871). The third rib (4872) may be positioned closer to the cell (360) or the opening (482) than the first rib (4871). For example, the distance between the second rib (4872) and the cell (360) may be equal to or substantially equal to the distance between the third rib (4873) and the cell (360).

[0279] Referring to FIG. 9, the contact portion (4872c) of the second rib (4872) may be positioned closer to the cell (360) than the contact portion (4871c) of the first rib (4871).

[0280] Referring to Fig. 10, ice (I1, I2, I3) generated in each cell (360) may be formed in a roughly spherical shape. Considering the outer surface of the spherical shape, the cell (360) may be formed convexly toward the ice guide (487) with respect to its center. Accordingly, the ice guide (487) is likely to first contact the surface corresponding to the center of the spherical shape when moving toward the ice.

[0281] If the first to third ribs (4871, 4872, 4873) are arranged in a straight line in one direction (e.g., in the X-axis direction), only the first rib (4871) closest to the center of the spherical ice comes into contact with the ice, and the second and third ribs (4872, 4873) on the sides are separated from the ice, making it difficult for the second and third ribs (4872, 4873) to actually provide a pressing force for ice breaking.

[0282] Accordingly, by positioning the second and third ribs (4872, 4873) on the side relatively close to the cell (360), when the ice guide (487) comes into contact with the ice, the first to third ribs (4871, 4872, 4873) can be guided to come into contact with the surface of the ice together.

[0283] In this way, the first to third ribs (4871, 4872, 4873) correspond to the shape of the outer surface of the ice, thereby differentiating the distance to the cell (360), thereby increasing the contact area between the ice guide (487) and the ice and preventing slipping (slipping) of the ice in the circumferential direction.

[0284] FIG. 11 is a cross-sectional view of an ice maker taken along line 11-11 of FIG. 2, FIG. 12 is an enlarged view of part “A” of FIG. 11, FIG. 13 is a view showing an ice guide in contact with ice when the ice maker according to the first embodiment of the present invention moves to an ice-breaking position, FIG. 14 is a view showing a second tray in contact with a pusher (fixed pusher) in the maximum ice-breaking position in FIG. 13, and FIG. 15 is a view showing the ice maker in a water supply position.

[0285] Referring to FIGS. 11 and 12, the first tray (300) according to the first embodiment of the present invention forms at least a portion of the cell (360), and the second tray (400) may form another portion of the cell (360).

[0286] The inner surface of the cell (360) may include a first cell surface (310a) formed by the first tray (300) and a second cell surface (410a) formed by the second tray (400). The first cell surface (310a) and the second cell surface (410a) may extend in one direction (e.g., in the circumferential direction) to form the cell (360).

[0287] Based on the center (C1) of the cell (360), the diameter (D1) of the cell (360) may be formed to be larger than the diameter (D2) of the portion where the first cell surface (310a) and the second cell surface (410a) come into contact. The portion where the first cell surface (310a) and the second cell surface (410a) come into contact may be understood as the boundary between the first tray (300) and the second tray (400).

[0288] The above diameter (D2) may form the diameter of the first opening of the first tray (300). The first opening of the first tray (300) may form an end (e.g., a lower end) of the first tray (300). The above diameter (D2) may form the diameter of the second opening (413) of the second tray (400). The second opening (413) of the second tray (400) may form an end (e.g., a upper end) of the second tray (400).

[0289] With respect to the center (C1) of the cell (360), the circumferential length of the first cell surface (310a) may be formed to be smaller than the circumferential length of the second cell surface (410a). With respect to the center (C1) of the cell (360), the central angle formed by the first cell surface (310a) may be formed to be smaller than the central angle formed by the second cell surface (410a).

[0290] Figure 11 shows the tray assembly in the ice-making position.

[0291] The second tray cover (480) may form an opening (482) through which the second tray wall (410) of the second tray (400) passes. The inner surface of the opening (482) and the outer surface of the second tray (400) may not contact each other and may be spaced apart by a set distance (△). With this configuration, the internal deformation of the second tray (400) may be reduced.

[0292] A moving guide (487) may be provided at the rear of the cell (360). One side (e.g., the bottom side) of the moving guide (487) may be connected to the cover wall (481) of the second tray cover (480). The moving guide (487) may extend in one direction (e.g., upward) from the shaft (520) toward the bracket (220).

[0293] The end of the above-mentioned moving guide (487), i.e., the tip (487b), may be positioned in the bracket groove (221f) of the bracket (220). The groove (221f) is formed by being recessed in one surface (e.g., the bottom surface) of the above-mentioned joining wall (221a), and at least a portion of the tip (487b) may be positioned inside the groove (221f).

[0294] When the moving guide (487) moves, the tip (487b) can be pulled out from the groove (221f). The groove (221f) can be formed so as not to interfere with the moving guide (487).

[0295] The above-mentioned moving guide (487) can be positioned apart from the side of the second extension wall (314) of the first tray (300) and the second extension wall (431) of the second tray (400).

[0296] The distance from the center of the above shaft (520) to the tip (487b) of the moving guide (487), i.e. the radius (R) L ) may be larger than the radius of any other part of the above moving guide (487).

[0297] The above contact portion (487c) may be formed at the end (e.g., the leading edge) of the tip (487b) based on the movement direction of the ice guide (487). The movement path of at least a portion of the ice guide (487) may be formed to interfere with or overlap with the surface of the ice attached to the first tray (300).

[0298] Referring to Fig. 13, during the freezing process, ice may be attached to the first tray (300). To this end, the first heater (490) may be driven to reduce the degree of adhesion of ice attached to the second tray (400).

[0299] As the first heater (490) is driven, ice can be separated from the second cell surface (410a) of the second tray (400) and discharged through the second opening (413) of the second tray (400) during the movement of the second tray (400). At this time, the second tray (400) can be deformed in a direction in which the second opening (413) expands to discharge the ice. For this purpose, the second tray (400) can be made of, for example, a flexible or malleable material.

[0300] When the second tray (400) moves, the moving guide (487) can move around the shaft (520). The moving guide (487) can move along the surface or edge of the first tray (300).

[0301] Among the entire portion of the above-mentioned moving guide portion (487), the contact portion (487c) can move along the surface shape of the first tray (300) while forming an end portion (e.g., a tip) of the above-mentioned moving guide (487). In this process, the contact portion (487c) can remove excessively formed frozen material (hereinafter, super-ice) on the surface of the first tray (300).

[0302] For example, the contact portion (487c) can move while being slightly spaced from the surface of the first tray (300). As another example, the contact portion (487c) can move while being in contact with the surface of the first tray (300).

[0303] When the second tray (400) moves further in the forward direction, the contact portion (487c) can come into contact with the ice attached to the first tray (300) and pressurize the ice. By the pressing, the ice can be separated from the first tray (300).

[0304] During the movement of the above-mentioned moving guide (487), after the contact portion (487c) moves along the surface of the first tray (300), the tip (487b) may then move along the surface or edge of the first tray (300). The tip (487b) may move slightly apart from or in contact with the surface of the first tray (300).

[0305] At the position where the contact portion (487c) presses the ice, the tip (487b) may be positioned at an edge adjacent to the first opening (310c) of the first tray (300). That is, the tip (487b) may not come into contact with the ice since it is positioned at a part (e.g., the rear) of the contact portion (487c) based on the moving direction of the second tray (400).

[0306] Referring to FIG. 14, after the contact portion (487c) pressurizes the ice and the ice is separated from the first tray, the second tray (400) can move slightly more forward toward the maximum ice-free position.

[0307] The separated ice falls and is stored in the ice bin (600), and the end (e.g., the lower end) of the second tray (400) may be deformed by contact with the pusher (540). Even if the ice is separated from the first tray (300) and located in the second tray (400) when the second tray (400) moves to the ice removal position, the ice can be separated from the second tray (400) by the pressure of the pusher (540).

[0308] When the ice-making operation is completed at the position of FIG. 14, the second tray assembly can move in the reverse direction and return to the ice-making position as shown in FIG. 11. When the water supply operation is started at the position of FIG. 11, the second tray assembly can move in the forward direction by a predetermined angle, for example, about 10 to 20 degrees, toward the water supply position as shown in FIG. 15. At the water supply position, fluid is supplied through the water supply unit (240), and the fluid can be supplied to a plurality of cells (360).

[0309] Through the above water supply unit (240), water can be supplied to the central cell (360) among the multiple cells (360). When the water supply is completed, the water can be supplied by spreading from the central cell (360) to the cells (360) on both sides after waiting for a set time. At this time, the water can flow through the water supply path (1435) inside the third extension wall (1433).

[0310] After the set time has elapsed, the second tray assembly can move backward to the ice-making position as shown in Fig. 11 and perform an ice-making operation. During the ice-making process, cold is supplied to the ice maker and the first heater (490) operates to produce transparent ice.

[0311] FIG. 16 is a drawing showing an ice maker according to a first embodiment of the present invention in which ice is first separated from a first tray, and FIG. 17 is a drawing showing an ice maker in FIG. 16 further moved to an ice-making position, so that an ice guide is in a position adjacent to the first tray.

[0312] Referring to FIGS. 16 and 17, after ice making is completed, ice generated during the ice-making process can be separated from the first tray (300) and placed in the second tray (400). To this end, after ice making is completed, the second heater (495) placed in the first tray (300) can be operated for a set time. Depending on the operation of the second heater (495), the degree of adhesion of ice in contact with the first tray (300) can be reduced.

[0313] When the driving unit (510) is driven forward by a set angle, the contact between the ice and the first tray (300) is separated, and the ice (I) can move to a position on the second tray (400). Meanwhile, since the adhesion force (or contact area) between the ice and the second tray (400) is formed to be large, the adhesion force (or contact area) between the ice and the first tray (300) can be easily separated during the ice-breaking process.

[0314] When the second tray (400) moves in the forward direction, the moving guide (487) of the second tray cover (480) can move in the forward direction together with the second tray (400b).

[0315] The above-mentioned moving guide (487) can move along the outer surface of the second extension wall (314) of the first tray (300). At this time, the moving guide (487) can move in a state in which it contacts the second extension wall (314) or is adjacent to the second extension wall (314) without contacting it.

[0316] The contact portion (487c) of the above-mentioned moving guide (487) can move to the contact end (319) of the first tray (300) or to a position adjacent to the contact end (319). In this process, ice debris (Id) that may exist in and around the contact end (319) can be separated from the tray assembly.

[0317] FIG. 18 is a drawing showing a second tray cover according to a second embodiment of the present invention, and FIG. 19 is a drawing showing ice in contact with an ice guide in an ice maker according to a second embodiment of the present invention.

[0318] Referring to FIGS. 18 and 19, a second tray cover (480a) according to a second embodiment of the present invention may include a cover wall (481) forming an opening (482). A description of the opening (482) may refer to the description of the first embodiment.

[0319] The second tray cover (480a) is provided on the cover wall (481) and may include a moving guide (1487) that helps move ice during the moving process.

[0320] The above-mentioned moving guide (1487) may be provided on a part (e.g., the rear part) of the cover wall (481). The number of the above-mentioned moving guides (1487) may correspond to the number of cells (360).

[0321] The above plurality of moving guides (1487) can be connected to each other by a guide connecting portion (488). The guide connecting portion (488) can be extended in a round shape to surround at least a portion of the outer circumference of the shaft (520).

[0322] The above-mentioned ice guide (1487) can, during the ice-separating process, pressurize the ice attached to the first tray (300) to separate the ice from the first tray (300). The above-mentioned ice guide (1487) can, during the ice-separating process, function to remove ice residue attached to the first tray (300) or ice residue existing in the contact area between the first tray (300) and the second tray (400).

[0323] The above-mentioned moving guide (1487) may be positioned adjacent to the axis of the shaft (520). The above-mentioned moving guide (1487) may have a groove (1487a) surrounding at least a portion of the shaft (520). The groove (1487a) is formed at an end (e.g., a lower end) of the moving guide (1487) and may be formed to be rounded with a predetermined curvature corresponding to the curvature of the outer circumferential surface of the shaft (520). The groove (1487a) may be understood as a portion connected to the guide connecting portion (488) and connected to the shaft (520).

[0324] The above-mentioned moving guide (1487) may include a tip (1487b) located at the furthest point relative to the center of the shaft (520). The above-mentioned moving guide (1487) may extend in one direction (e.g., upward) toward the first tray (300) from the groove (1487a). The tip (1487b) may be formed at one end (e.g., the upper end) of the above-mentioned moving guide (487).

[0325] The above-described moving guide (1487) may include a contact portion (1487c) that comes into contact with ice during the moving process. The contact portion (1487c) may be formed in a portion extending in one direction (e.g., downward) from the tip (1487b). The contact portion (1487c) may form a portion of one surface (e.g., the upper surface) of the moving guide (1487).

[0326] The above-mentioned moving guide (1487) may include a support portion (1487d) connected to the cover wall (481). The support portion (1487d) forms a part of the other end (e.g., the lower end) of the moving guide (1487) and may be connected to one surface (e.g., the upper surface) of the cover wall (481).

[0327] The moving guide (1487) may include a first reinforcing portion (1487e) extending in one direction (e.g., downward) from the contact portion (1487c). An end (e.g., a lower end) of the first reinforcing portion (1487e) may be connected to the cover wall (481). The moving guide (1487) may include a second reinforcing portion (1487f) extending from one end (e.g., a rear end) of the tip (1487b).

[0328] The contact portion (1487c) of each ice guide (1487) may include an inclined surface, a curved surface, or a rounded surface. The contact portion (1487c) may include a first part (1487c1) formed at a position close to the center of the cell (360). During the movement of the ice guide (487), the first part (1487c1) may contact the central surface of the ice.

[0329] The above contact portion (1487c) may include a second part (1487c2) extending to one side of the first part (1487c1). The second part (1487c2) may be positioned at a position spaced apart from the center of the cell (360) in the circumferential direction. During the process of moving the ice guide (1487), the second part (1487c2) may contact a surface spaced apart from the center surface of the ice in the circumferential direction in the process.

[0330] The above contact portion (1487c) may include a third part (1487c3) extending to the other side of the first part (1487c1). The third part (1487c3) may be positioned at a position spaced apart from the center of the cell (360) in the other direction in the circumferential direction. During the process of moving the ice guide (1487), the third part (1487c3) may contact a surface spaced apart from the center surface of the ice in the other direction in the circumferential direction.

[0331] The second part (1487c2) and the third part (1487c3) may be positioned on both sides of the first part (1487c1). The first part (1487c1) may be referred to as a “central contact portion,” and the second and third parts (1487c2, 1487c3) may be referred to as “lateral contact portions.”

[0332] The second part (1487c2) and the third part (1487c3) may extend in a slanted, bent, or rounded manner from the first part (1487c1) toward the cell (360).

[0333] The second part (1487c2) may be positioned closer to the cell (360) or the opening (482) than the first part (1487c1). The third part (1487c3) may be positioned closer to the cell (360) or the opening (482) than the first part (1487c1).

[0334] Referring to Fig. 19, ice (I1, I2, I3) generated in each cell (360) may be formed in a roughly spherical shape. Considering the outer surface of the spherical shape, the cell (360) may be formed convexly toward the ice guide (1487) with respect to its center. Accordingly, the ice guide (1487) is likely to first contact the surface corresponding to the center of the spherical shape when moving toward the ice.

[0335] If the first to third ribs (4871, 4872, 4873) are arranged in a straight line in one direction (e.g., X-axis direction), only the first part (1487c1) closest to the center of the spherical ice comes into contact with the ice, and the second and third parts (1487c2, 1487c3) on the sides are separated from the ice, so that the second and third parts (1487c2, 1487c3) have difficulty actually providing a pressing force for ice breaking.

[0336] Accordingly, by positioning the second and third parts (1487c2, 1487c3) on the side relatively close to the cell (360), when the ice guide (1487) comes into contact with the ice, the first to third parts (1487c1, 1487c2, 1487c3) can be guided to come into contact with the surface of the ice together. In this way, by differentiating the distance to the cell (360) according to the shape of the outer surface of the ice, the contact area between the ice guide (1487) and the ice can be increased, and slipping (slipping) of the ice in the circumferential direction can be prevented.

[0337] Fig. 20 is an exploded perspective view of an ice maker according to a third embodiment of the present invention. Referring to Fig. 20, an ice maker (200b) according to the third embodiment of the present invention may include a first tray (900) forming at least a portion of a cell (360).

[0338] The ice maker (200b) may include a second tray (400b) forming another part of the cell (360). A plurality of cells (360) may be defined by the first tray (900) and the second tray (400b). For example, the plurality of cells (360) may include three cells (360).

[0339] The above ice maker (200b) may include a second tray cover (480b) and a second tray supporter (450b). The description of the second tray cover (480d) and the second tray supporter (450d) may refer to the contents described in the previous embodiment.

[0340] The above ice maker (200b) may include a lift (560) as a contact mechanism that moves based on the center of the shaft (520) so that the second tray assembly can be contacted with the first tray (900). The description of the lift (560) may refer to the description in the previous embodiment.

[0341] The above ice maker (200b) may include a first heater (490). The description of the first heater (490) may refer to the contents described in the previous embodiment.

[0342] The ice maker (200b) may include a first tray supporter (350). At least a portion of the first tray supporter (350) may be positioned on one side (e.g., the lower side) of the first tray (900).

[0343] The first tray supporter (350) may include a supporter wall (351) forming an opening (352). The supporter wall (351) may be placed on one side (e.g., the lower side) of the second extension wall (915) of the first tray (900).

[0344] The above opening (352) may be formed so that at least a portion of the first tray supporter (350) passes through it so that at least a portion of the first tray (900) passes through it. The opening (352) may be formed to have a predetermined curvature corresponding to the shape of the outer surface of the cell (360).

[0345] The first tray supporter (350) may include a tray coupling portion (354) that protrudes in one direction (e.g., upward) from the supporter wall (351). A plurality of the tray coupling portions (354) are provided along the perimeter of one surface (e.g., the upper surface) of the supporter wall (351) and may be inserted into the fastening portion (915a) of the first tray (900). The fastening portion (915a) may include a groove or a hole.

[0346] FIG. 21 is a perspective view showing the configuration of a first tray according to a third embodiment of the present invention, FIG. 22 is a plan view showing the configuration of a first tray according to a third embodiment of the present invention, FIG. 23 is a cross-sectional view taken along line 23-23 of FIG. 21, and FIG. 24 is a cross-sectional view taken along line 24-24 of FIG. 21.

[0347] Referring to FIGS. 21 to 24, a first tray (900) according to a third embodiment of the present invention may define a first cell (910b) that is a part of a cell (360). Considering an ice maker (200b) equipped with a plurality of cells (360), the first tray (900) may include a plurality of first cells (910b).

[0348] The first tray (900) may include a first tray wall (910) forming a part of the cell (360). The first tray wall (910) may include a first cell wall (911) defining a first cell surface (910a). It can be understood that the inner surface of the first cell wall (911) forms the first cell surface (910a), and the first cell surface (910a) defines an outer surface of the first cell (910b).

[0349] The first tray wall (910) may include a first opening (910c). The first opening (910c) forms an end (e.g., a lower end) of the first tray wall (910) and may be in contact with the second tray (400b).

[0350] The first tray wall (910) may include a first extension wall (913) extending upward from a portion of the perimeter of the first cell wall (911). A plurality of the first extension walls (913) may be provided on both sides of the first cell wall (911).

[0351] An opening (913a) is formed between the plurality of first extension walls (913), and the first cell wall (911) can be exposed to the outside of the first tray (900) through the opening (913a).

[0352] The first tray wall (910) may include a second extension wall (915) that is connected to an end (e.g., an upper end) of the first extension wall (913) and extends in a first direction (e.g., a horizontal direction). The second extension wall (915) may extend from one side (e.g., an upper side) of a plurality of first cells (910b). A fastening portion (915a) that is coupled to a first tray supporter (350) may be formed on the second extension wall (915).

[0353] The first tray wall (910) may extend from the second extension wall (915) and include a first connecting wall (916) connecting the spaces between the plurality of first cells (910b).

[0354] The first tray wall (910) may include a second connecting wall (917) extending recessed from the second extension wall (915) and connected to the first cell wall (911). The second connecting wall (917) may be connected to the periphery of the first cell wall (911).

[0355] The second connecting wall (917) may include a first wall (917a) extending in a first direction (e.g., horizontally) from the rear of the first cell wall (911). The second connecting wall (917) may include a second wall (917b) extending slanted or rounded in one side from the first wall (917a). The second connecting wall (917) may include a third wall (917c) extending slanted or rounded in the other side from the first wall (917a).

[0356] The first tray (900) may include a drain guide (918) extending to one side (e.g., the upper side) of the first cell wall (911). The drain guide (918) may include a guide wall.

[0357] The above drainage guide (918) is arranged to surround at least a portion of the through holes (911a, 911b, 911c) so as to guide the fluid discharged through the through holes (911a, 911b, 911c) to the outside of the first cell wall (811). The through holes (911a, 911b, 911c) can be understood as a portion that discharges air during the ice-making process in order to prevent an air pocket phenomenon in the cell (360).

[0358] The above drainage guide (918) may include a first drainage guide (918a) provided on the outside of the first cell (910b) on the central side among the plurality of central cells (360). The first drainage guide (918a) may be configured to cover a first portion (e.g., a side portion) and a second portion (e.g., a rear portion) of the first through-hole (911a) and open toward a third portion (e.g., a front portion). The fluid discharged through the first through-hole (911a) may not flow to the first portion (e.g., a side portion) and the second portion (e.g., a rear portion) of the first cell wall (911) due to the first drainage guide (918a) and may be discharged toward the third portion (e.g., a front portion).

[0359] A space (919a) can be formed between the first drainage guide (918a) and the first wall (917a).

[0360] The first cell wall (911) forming the first cell (910b) on the central side can form a guide surface through which the fluid discharged from the water supply unit (240) flows down. Therefore, even if the fluid discharged through the first through hole (911a) exists as ice on the first cell wall (911), it is washed away by the fluid supplied from the water supply unit (240), so that problems due to the ice may not occur.

[0361] The end of the first drainage guide (918a) is connected to the first extension wall (913), and the portion where the first drainage guide (918a) and the first extension wall (913) are connected can define the opening (913a). The first extension wall (913) can be connected to both ends of the first drainage guide (918a).

[0362] The above drainage guide (918) may include a second drainage guide (918b) and a third drainage guide (918c) provided on the outside of the first cell (910b) on the left and right sides among a plurality of central cells (360). The second drainage guide (918b) and the third drainage guide (918c) may have the same configuration.

[0363] The second drainage guide (918b) may be provided outside the first cell (910b) of the first side. The third drainage guide (918c) may be provided outside the first cell (910b) of the second side. The following description will be based on the second drainage guide (918b), and the description thereof may be equally applied to the third drainage guide (918c).

[0364] The second drainage guide (918b) may be configured to cover a first portion (e.g., a side portion) and a second portion (e.g., a front portion) of the second through hole (911b) and open toward a third portion (e.g., a rear portion). The first cell wall (911) defining the first cell (910b) of the first side is not supplied with water through the water supply unit (240), and as described above, the fluid supplied to the central cell may be supplied with water through a water spreading phenomenon.

[0365] Accordingly, when ice forms on the first cell wall (911) of the first side, washing it away by the water supply is limited. To solve this problem, the second drainage guide (918b) can guide the fluid discharged through the second through hole (911b) to flow to one side (e.g., the rear) of the first cell wall (911).

[0366] A drainage opening (917d) may be formed in the second connecting wall (917) defining the first cell (910b) of the first side. The drainage opening (917d) may be formed at an end (e.g., a lower end) of the first wall (917a). By virtue of the drainage opening (917d), the end of the first wall (917a) and the first cell wall (911) may be spaced apart from each other.

[0367] The fluid guided to one side (e.g., rear) of the first cell wall (911) by the second drainage guide (918b) can flow through the drainage opening (917d). However, the fluid does not flow into the interior of the cell (360), but can flow around the second extension wall (431) of the second tray (400b) (see FIG. 29b).

[0368] A channel through which fluid flows can be formed in the space between the first tray (900) and the second extension wall (431). To form the channel, the second connecting wall (917) of the first tray (900) and the second extension wall (431) of the second tray (400b) can be spaced apart from each other. Fluid or ice remaining in the channel can be removed by interference from the ice guide (2487) during the ice removal process.

[0369] The third drainage guide (918c) is provided on the outside of the first cell wall (911) defining the first cell (910b) of the second side, and can be configured to cover the first part (e.g., the side part) and the second part (e.g., the front part) of the third through hole (911c) and open toward the third part (e.g., the rear part).

[0370] FIG. 25 is a drawing showing the configuration of a second tray assembly according to a third embodiment of the present invention, FIG. 26 is a drawing showing the configuration of a second tray cover according to a third embodiment of the present invention, FIG. 27 is a side view of the second tray cover of FIG. 26, and FIG. 28 is a cross-sectional view showing the configuration of an ice maker according to a third embodiment of the present invention.

[0371] Referring to FIGS. 25 to 28, a second tray assembly according to a third embodiment of the present invention may include a second tray (400b), a second tray supporter (450b), and a second tray cover (480b).

[0372] The second tray cover (480b) may include a separating guide (2487) provided on the cover wall (481). The separating guide (2487) may be provided to contact the ice for separating the manufactured ice. As another example, the separating guide (2487) may be provided to remove any remaining ice present on or around the surface of the tray assembly.

[0373] The above-mentioned moving guide (2487) may be provided on the edge side of the cover wall (481). For example, the above-mentioned moving guide (2487) may be placed on the edge side of the second tray cover (480) on which the shaft (520) is placed.

[0374] The above moving guides (2487) may be provided in multiple numbers. The multiple moving guides (487) may be arranged in one direction (e.g., X-axis direction) in which the multiple cells (360) are arranged, corresponding to the multiple cells (360).

[0375] The above plurality of moving guides (487) can be connected to each other by a guide connecting portion (488). The guide connecting portion (488) can be extended in a round shape to surround at least a portion of the outer circumference of the shaft (520).

[0376] Each moving guide (2487) is provided to be movable for moving ice generated from a plurality of cells (360), and the moving guide (2487) can come into contact with the ice while moving.

[0377] The above-mentioned moving guide (2487) can move along the surface of the first tray (900) during the moving process. For example, the moving guide (2487) can move along the surface shape of the first tray (200) while in contact with the surface of the first tray (900) or adjacent to the surface of the first tray (300).

[0378] The above-mentioned moving guide (2487) may have a groove (2488a) that surrounds at least a portion of the shaft (520) and constitutes a first part. The groove (2488a) is formed at an end (e.g., a lower end) of the moving guide (2487) and may be formed to be rounded with a predetermined curvature corresponding to the curvature of the outer surface of the shaft (520).

[0379] The above-mentioned moving guide (2487) may be located at the furthest point relative to the center of the shaft (520) and may include a tip (2488b) constituting a second part. The above-mentioned moving guide (2487) may extend in one direction (e.g., upward) in a roughly fan-shaped shape from the groove (2488a). The tip (2488b) may form a point on the outer surface of the fan-shaped shape.

[0380] The above-mentioned moving guide (2487) may include a contact portion (2488c) that comes into contact with ice during the moving process and constitutes a third part. The contact portion (2488c) may be formed at a portion extending in one direction (e.g., downward) from the tip (2488b). The contact portion (2488c) may be formed at one end (e.g., the tip) based on the moving direction of the above-mentioned moving guide (2487).

[0381] The distance between the contact portion (2488c) and the groove portion (2488) may be smaller than the distance between the tip (2488b) and the groove portion (2488a).

[0382] The above-mentioned ice guide (2487) may include a guide groove (2488d) that is sunken into the contact portion (2488c) and constitutes a fourth part. By means of the guide groove (2488d), the contact portion (2488c) may have a hook shape that sharply protrudes from one end (e.g., the tip) of the ice guide (2487). The guide groove (2488d) may provide a space for storing the removed ice when the ice guide (2487) removes the ice on the first tray (900).

[0383] The above-described moving guide (2487) may include a support portion (2488e) that is connected to the cover wall (481) and constitutes a fifth part. The support portion (2488e) forms a part of one end (e.g., the lower end) of the moving guide (2487) and may be connected to one surface (e.g., the upper surface) of the cover wall (481).

[0384] The above-mentioned moving guide (2487) may include a first reinforcing member (2488f) extending in one direction (e.g., downward) from the guide groove (2488d). An end (e.g., a lower end) of the first reinforcing member (2488f) may be connected to the cover wall (481).

[0385] The above-mentioned moving guide (2487) may include a second reinforcing portion (2488g) extending circumferentially from one end (e.g., the rear end) of the tip (2488b). The second reinforcing portion (2488g) may form a portion of the outer peripheral surface of a fan shape.

[0386] Since the strength of the ice guide (2487) can be reinforced by the configuration of the first reinforcing portion (2488f) and the second reinforcing portion (2488g), the ice guide (2487) can be prevented from being damaged by pressure or impact generated when the ice guide (2487) comes into contact with ice or ice floes. The first reinforcing portion (2488f) and the second reinforcing portion (2488g) can constitute the fifth and sixth parts of the ice guide.

[0387] The above-described plurality of moving guides (2487) may be formed at different distances from the cells (360). Accordingly, during the process of moving the above-described plurality of moving guides (2487), sequential moving may occur in the plurality of cells (360).

[0388] The above-described plurality of moving guides (2487) may include a first moving guide (2487a) positioned corresponding to the central cell (360). The above-described plurality of moving guides (2487) may include a second moving guide (2487b) and a third moving guide (2487c) positioned corresponding to the two-sided cells (360).

[0389] The first moving guide (2487a) may be provided between the second moving guide (2487b) and the third moving guide (2487c). The first moving guide (2487a) may be referred to as a "central guide", and the second and third moving guides (2487b, 2487c) may be referred to as "lateral guides". The second moving guide (2487b) and the third moving guide (2487c) may have the same shape.

[0390] The first moving guide (2487a) may be located relatively close to the cell (360), and the second and third moving guides (2487b, 2487c) may be located at relatively far distances from the cell (360). That is, the distance between the first moving guide (2487a) and the corresponding cell (360) may be smaller than the distance between the second moving guide (2487b) and the corresponding cell (360).

[0391] Based on the contact portion (2488c) provided in the above-mentioned moving guide (2487), the first contact portion (2488c1) provided in the first moving guide (2487a) may be located closer to the ice making room (360) than the second contact portion (2488c2) provided in the second and third moving guides (2487b, 2487c).

[0392] The first angle (θ1) formed by the first contact portion (2488c1) with respect to the extension line (ℓ1) passing through the support portion (2488e) in one direction (e.g., in the up-down direction) may be smaller than the second angle (θ2) formed by the second contact portion (2488c2). According to this configuration, when the second tray cover (480b) moves, the first ice-moving guide (2487a) can first come into contact with the ice to perform the ice-moving, and thereafter, the second ice-moving guide (2487b) and the third ice-moving guide (2487c) can come into contact with the ice to perform the ice-moving. That is, since sequential ice-moving can be performed, the ice-moving force can be reduced, thereby reducing the motor load.

[0393] Referring to FIG. 28, the bracket (220) may include a support wall (229) for supporting the first tray (900). The support wall (229) may extend in one direction (e.g., downward) from the joining wall (221a, see FIG. 11).

[0394] The above support wall (229) can perform the function of reducing the deformation of the first tray (900) and preventing a separation defect due to deformation of the first tray (900) during the separation process. Here, the first tray (900) can be composed of a flexible or ductile material.

[0395] The above support wall (229) may include a first support wall (229a) that supports the drainage guide (918) of the first tray (900). The first support wall (229a) may have a bent shape corresponding to the shape of the drainage guide (918).

[0396] The first support wall (229a) may be in contact with the drainage guide (918). The first support wall (229a) may extend along the bent drainage guide (918). The first support wall (229a) may be arranged to surround at least a portion of the drainage guide (918).

[0397] The above support wall (229) may include a second support wall (229b) that supports the second connecting wall (917) of the first tray (900). The second support wall (229b) may have a bent shape corresponding to the shape of the second connecting wall (917).

[0398] The second support wall (229b) may be in contact with the second connecting wall (917). The second support wall (229b) may extend along the second connecting wall (917). The second support wall (229b) may be arranged to surround at least a portion of the second connecting wall (917).

[0399] By strengthening the internal deformation of the second connecting wall (917a), the deformation amount of the second connecting wall (917a) can be reduced when the moving guide (2487) comes into contact with the first tray (900).

[0400] In the first cell (910b) on the central side, water can be supplied through a water supply unit (240). Water is supplied first to the first cell (910b) on the central side, and the fluid added thereafter can be supplied (water spread) by branching to the first side cell and the second side cell along the water supply path (1436) on the inside of the third extension wall (1433).

[0401] FIG. 29a is a drawing showing the configuration of a central moving guide and a tray assembly in an ice maker according to a third embodiment, FIG. 29b is a drawing showing the configuration of a side moving guide and a tray assembly in an ice maker according to a third embodiment of the present invention, FIG. 30 is a drawing showing an appearance of a moving guide moving and coming into contact with ice in an ice maker according to a third embodiment of the present invention, and FIG. 31 is a drawing showing an appearance of a side moving guide moving and coming into contact with frozen material in an ice maker according to a third embodiment of the present invention.

[0402] Referring to FIGS. 29a and 29b, the first moving guide (2487a) provided in a part (e.g., the rear) of the central cell (360) is positioned at a relatively long distance from the cell (360). The first moving guide (2487a), particularly the first contact portion (2488c1), may be positioned at a first set distance (△) from the edge of the first tray (900).

[0403] On the other hand, the second moving guide (2487b) or the third moving guide (2487c) provided in a part (e.g., the rear) of the lateral cell (360) is positioned at a relatively close distance from the cell (360). The second moving guide (2487b), particularly the second contact portion (2488c2), may be positioned at a second set distance (△) from the edge of the first tray (900).

[0404] The above second setting distance (△) may be greater than the above first setting distance (△).

[0405] When the second tray (400b) moves to the moving position, the first contact portion (2488c) of the first moving guide (2487a) can move along the surface of the first tray (900). The first moving guide (2487a) can contact the first tray (900) before the second and third moving guides (2487b, 2487c) or reach a position adjacent to the first tray (900).

[0406] When the first moving guide (2487a) moves while contacting or reaching a position adjacent to the first tray (900), ice crumbs existing on the first tray (900) side can be separated by the first moving guide (2487a).

[0407] The separated ice crumbs are stored in the guide groove (2488d) of the first ice guide (2487a) and can be discharged in the opposite direction of the cell (360).

[0408] As the first ice guide (2487a) continues to move, the first ice guide (2487a) may come into contact with the frozen ice or come into contact with the edge of the first tray (900) to separate the ice from the first tray (900). At this time, the first tray (900) may be deformed, and the separated ice may be stored in the ice bin (600) (see FIG. 30).

[0409] Meanwhile, in the central cell (360), fluid is discharged through the first through-hole (911a), and freezing may exist in the discharged first through-hole (911a). The frozen material can be removed by the supplied water when the next water supply operation is performed.

[0410] The second moving guide (2487b) and the third moving guide (2487c) can move along the surface of the first tray (900). The second moving guide (2487b) and the third moving guide (2487c) can contact the first tray (900) later than the first moving guide (2487a) or reach a position adjacent to the first tray (900).

[0411] For example, when the first ice guide (2487a) passes the edge of the first tray (900) and begins to contact the frozen ice, the second ice guide (2487b) and the third ice guide (2487c) may contact the first tray (900) or reach a position adjacent to the first tray (900).

[0412] When the second and third moving guides (2487b, 2487c) move while contacting or reaching a position adjacent to the first tray (900), ice crumbs existing on the first tray (900) side can be separated by the second and third moving guides (2487b, 2487c) (see FIG. 31). The separated ice crumbs can be stored in the guide grooves (2488d) of the second and third moving guides (2487b, 2487c) and discharged in the opposite direction of the cell (360).

[0413] Meanwhile, there may be residual ice in the drainage opening (917d). When the second and third ice guides (2487b, 2487c) pass through the drainage opening (917d), the residual ice in the drainage may come into contact with the second and third ice guides (2487b, 2487c) and be separated.

[0414] The separated drain ice is stored in the guide groove (2488d) of the second and third ice guides (2487b, 2487c) and can be discharged in the opposite direction of the cell (360). By this action, the separated ice is easily separated, and ice crumbs or drain ice can be easily removed from the first tray (900).

[0415] The present invention relates to an ice maker and / or a refrigerator equipped with an ice maker, and has remarkable industrial applicability because it can improve ice-breaking performance in a tray forming cells by an ice-breaking guide.
