Description

refrigerator

[0001] The present specification relates to an ice maker and / or a refrigerator equipped with an ice maker.

[0002] In general, a refrigerator is a home appliance that can store food at a low temperature in an internal storage space that is sealed by a door. By using cold to cool the inside of the storage space, the stored food can be kept in a refrigerated or frozen state.

[0003] Refrigerators typically come equipped with an ice maker to produce ice. This ice maker draws water from a water source or water tank into a tray, cools the water, and creates ice. Furthermore, the ice maker can remove the ice from the tray using a heating or twisting method. This type of ice maker, which automatically supplies water and removes ice, is designed to open upward to scoop up the formed ice.

[0004] Ice produced by an ice maker with this type of structure has at least one flat surface, such as a crescent or cubic shape. Meanwhile, spherical ice can be more convenient to use and provide a unique user experience. Furthermore, by minimizing the contact area between ice cubes during storage, clumping of ice cubes can be minimized. Furthermore, recent efforts have been made to produce transparent ice.

Even if the freezer compartment (32) can be opened and closed by a single door (30), it may be provided so as to be separated into two spaces.

[0149] In this embodiment, the freezer (32) may be referred to as a first storage room, and the refrigerator (18) may be referred to as a second storage room. The freezer (32) may be equipped with an ice maker (200) capable of producing ice. The ice maker (200) may be located, for example, in a portion of the freezer (32) (e.g., an upper space).

[0150] An ice bin (60) into which ice produced by the ice maker (200) is dropped and stored may be placed on one side (e.g., the lower side) of the ice maker (200). A user may take the ice bin (600) out of the freezer (32) and use the ice stored in the ice bin (60). The ice bin (60) may be coupled to one side (e.g., the upper side) of a wall dividing a first space (e.g., the upper space) and a second space (e.g., the lower space) of the freezer (32).

[0151] Although not shown, the cabinet (14) is provided with a duct (not shown) for supplying cold to the ice maker (200). The duct guides the cold that has exchanged heat with the refrigerant flowing through the evaporator toward the ice maker (200). For example, the duct may be arranged at one side (e.g., the rear) of the cabinet (14) and discharge the cold toward the other side (e.g., the front) of the cabinet (14). The ice maker (200) may be positioned at one side (e.g., the front) of the duct. Although not limited, the discharge port of the duct may be provided at one or more of the first side wall (e.g., the rear wall) and the second side wall (e.g., the upper wall) of the freezer (32).

[0152] Although it has been described above that the ice maker (200) is provided in the freezer (32), the space in which the ice maker (200) can be located is not limited to the freezer (32), and the ice maker (200) can be located in various spaces as long as cold can be supplied. Hereinafter, it will be described that the ice maker (200) is located in the storage room.

[0153] FIG. 2 is a perspective view showing an ice maker according to a first embodiment of the present invention, and FIG. 3 is an exploded perspective view of the ice maker according to the first embodiment of the present invention.

[0154] Referring to FIGS. 2 and 3, an ice maker (200) according to a first embodiment of the present invention may include a bracket (220) that supports a tray assembly. Each component of the ice maker (200) may be provided inside or outside the bracket (220), so that the ice maker (200) may form a single assembly.

[0155] The bracket (220) may be coupled to at least one surface of the storage compartment. The bracket (220) may include a first wall (221) having a through hole (226) formed therein. At least a portion of the first wall (221) may extend in a first direction (e.g., horizontally) and may be coupled to one surface of the storage compartment.

[0156] 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 the tray assembly and the driving unit (510) are arranged.

[0157] One of the two second walls (222) may cover the driving unit (510). The other of the two second walls (222) may function as a barrier to prevent ice from falling into the ice bin (60) or ice stored in the ice bin (60) from falling, and may form a wall penetration hole (222a) with at least a portion thereof penetrated to prevent frost formation.

[0158] 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).

[0159] 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).

[0160] 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).

[0161] 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.

[0162] The first wall (221) may include a through hole that functions as an outlet through which cold air passing through the tray assembly is discharged. A plurality of the through holes may be formed.

[0163] 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).

[0164] For example, the guide wall (225) may include a portion extending roundly from the third wall (223) toward the cell (360). The cell (360) may be arranged closer to one end (e.g., the front end) of the ice maker in one direction (e.g., the front-back direction).

[0165] 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).

[0166] The above ice maker (200) may include a first tray assembly and a second tray assembly.

[0167] The first tray assembly may include a first tray (300), a first tray case, or both the first tray (300) and the first tray case. For example, in the present embodiment, the first tray assembly may include a first tray (300).

[0168] The second tray assembly may include a second tray (400) and a second tray case. The second tray case may include at least one of a second tray supporter and a second tray cover.

[0169] The above bracket (220) can define at least a portion of a space that accommodates the first tray assembly and the second tray assembly.

[0170] 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).

[0171] 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).

[0172] The ice maker (200) may include a cell (see 360 ​​in FIG. 4), 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).

[0173] 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.

[0174] 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.

[0175] 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).

[0176] In this embodiment, the first tray (300) and the second tray (400) may be arranged in one direction (e.g., up and down) while forming a 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.

[0177] 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).

[0178] 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.

[0179] 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).

[0180] 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).

[0181] The second tray case may include, for example, a second tray cover (480) and a second tray supporter (450). For example, the second tray (400), the second tray supporter (450), and the second tray cover (480) may be joined by a fastening member (457).

[0182] 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). The cover wall (481) may be positioned on one side (e.g., the upper side) of the first extension wall (420, see FIG. 7) of the second tray (400).

[0183] The first extension wall (420) may be provided with a contact protrusion (428) that comes into contact with the second tray cover (480). The contact protrusion (428) may extend in one direction (e.g., upward) from the first extension wall (420).

[0184] An insertion hole (481a) into which the contact protrusion (428) is inserted may be formed in the cover wall (481) of the second tray cover (480). The contact protrusion (428) may contact the stopper (250) (see FIG. 5).

[0185] In the process of the second tray (400) moving to the ice-making position, the contact projection (428) is pressed by the stopper (250), so that the adhesion of the first and second trays (300, 400) can be improved.

[0186] 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). The opening (482) may be configured to have an area larger than the cross-sectional area of ​​a plurality of second cells of the second tray (400) so that the plurality of second cells may pass through it.

[0187] 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 (△). For example, the inner surface of the opening (482) and the outer surface of the second part (412) of the second tray (400) may be spaced apart from each other. With this configuration, the internal deformation of the second tray (400) may be reduced (see FIG. 5).

[0188] 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, see FIG. 7) of the second tray (400) and the supporter fastening portion (456) of the second tray supporter (450).

[0189] In a state where the cover fastening portion (485) is connected to the fastening portion (425) and the supporter fastening portion (456), the fastening member (457) can be fastened to one side (e.g., the lower side) of the second tray supporter (450).

[0190] 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). 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).

[0191] The second tray (400) may include a peripheral wall (430, see FIG. 7) that surrounds a portion of the first tray (300) while in contact with the first tray (300).

[0192] The ice maker (200) may include a driving unit (510) that provides driving force. The driving unit (510) may include a driving motor. By receiving the driving force of the driving unit (510), the second tray (400) may move relative to the first tray (300).

[0193] The second tray supporter (450) may include two extension parts (455) in which through holes (455a) are formed. The two extension parts (455) may be provided on both sides of the second tray supporter (450). The ice maker (200) may include a shaft (520) penetrating the through holes (455a). The shaft (520) extends between the two extension parts (455) and may rotate by receiving power from the driving unit (510).

[0194] 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.

[0195] 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).

[0196] 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, see FIG. 7) of the second tray (400) may be mounted on the third wall (453).

[0197] A joining portion (459) may be formed on the third wall (453) to which the first edge (422a, see FIG. 11) of the second tray (400) is joined. The joining portion (459) may include a through hole through which the first edge (422a) is inserted.

[0198] By inserting the first edge (422a) into the connecting portion (459) and the second tray cover (480) covering the first extension wall (420) of the second tray (400), the surface of the second tray (400) can be shielded from the outside. With this configuration, the freezing phenomenon between the second tray (400) and the second tray cover (480) due to the supercharged water can be reduced (see FIG. 5).

[0199] An insertion portion (458a) may be formed in the third wall (453) to which the second edge (422b, see FIG. 11) of the second tray (400) is coupled. The insertion portion (458a) may include a groove recessed from the third wall (453) to allow the second edge (422b) to be inserted.

[0200] 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 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 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).

[0201] The surface of the second tray (400) can be shielded from the outside by the second edge (422b) being inserted into the insertion portion (458a) and the second tray cover (480) covering the first extension wall (420, see FIG. 12) of the second tray (400). With this configuration, the freezing phenomenon between the tray (400) and the second tray cover (480) due to the supercharged water can be reduced (see FIG. 5).

[0202] The second tray supporter (450) may be formed with a receiving space (453a) that is sunken in one direction (e.g., downward) from the third wall (453). A portion of the second cell of the second tray (400) may be received in the receiving space (453a).

[0203] A transparent ice heater (490) for applying heat to the second tray (400) during the ice-making process may be placed in the above-mentioned receiving space (453a). The transparent ice heater (490) may be placed 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). The transparent ice heater (490) may be a wire-type heater.

[0204] The second tray supporter (450) may include a fourth wall (454) forming one side (e.g., a rear side) of the second tray supporter (450). The outer surface of the second tray supporter (450) may be defined by the first to fourth walls (451, 452, 453, 454).

[0205] A holder (530) may be provided at both ends of the shaft (440). The holder (530) may include a first holder (531) connecting the shaft (520) and the driving unit (510). The first holder (531) may be coupled to one end of the shaft (520) and may be positioned between the extension (455) and the driving unit (510).

[0206] The first holder (531) is configured to have an open side end portion so that the shaft (520) passes through it, and the shaft (520) can be coupled to the driving unit (510) by passing through the first holder (531).

[0207] The holder (530) may include a second holder (532) coupled to the other end of the shaft (520). The second holder (532) is positioned on the outside of the extension (455), and the shaft (520) may pass through the through hole (455a) and be supported by the second holder (532).

[0208] The above driving unit (510) may include a motor and a plurality of gears.

[0209] 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 (60) during the movement process.

[0210] The above driving unit (510) may include a cam that moves or rotates by receiving power from the motor. The ice maker (200) may include a sensor that detects the movement or rotation of the cam.

[0211] 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.

[0212] The above ice maker (200) may include a pusher (540). The pusher (540) may be placed on the bracket (220), for example.

[0213] The pusher (540) may include a coupling plate (542) coupled to the bracket (220) and at least one pushing bar (544) extending from the coupling plate (542). For example, the pusher (540) may include a number of pushing bars (544) equal to the number of cells (360), but is not limited thereto.

[0214] The pushing bar (544) can push out ice located in the cell (360). For example, the pushing bar (544) 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 is in contact.

[0215] 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 change shape when pressed by the pusher (540). Although not limited, the second tray (400) may be formed of a silicone material, for example.

[0216] 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).

[0217] 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).

[0218] 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 easily restored to its original shape.

[0219] 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 (ice contact area), ice separation can be easily achieved.

[0220] 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.

[0221] 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).

[0222] 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.

[0223] Fig. 4 is a longitudinal cross-sectional view of an ice maker according to a first embodiment of the present invention, and Fig. 5 is a cross-sectional view showing a main part of Fig. 4.

[0224] Referring to FIGS. 4 and 5, the bracket (220) according to the first embodiment of the present invention may include a joining wall (221a) joined to the first tray (300). The joining wall (221a) may be formed to be stepped in one direction (e.g., downward) from the first wall (221) forming one surface (e.g., upper surface) of the bracket (220). The distance between the joining wall (221a) and the first tray (300) may be shorter than the distance between the first wall (221) and the first tray (300).

[0225] The first tray (300) may be fastened to the connecting wall (221a) by a predetermined fastening member. A fastening groove (325) into which the fastening member is fastened may be formed in a portion (e.g., the upper portion) of the first tray (300).

[0226] The bracket (220) may include a support wall (229) for supporting the first tray (300). The support wall (229) may extend in one direction (e.g., downward) from the joining wall (221a). The support wall (229) may be configured to support the guide wall (320) of the first tray (300).

[0227] The above support wall (229) has a bent or rounded shape corresponding to the shape of the guide wall (320) and can be in contact with the guide wall (320). The support wall (229) can extend along the bent or rounded guide wall (320). The support wall (229) can be arranged to surround at least a portion of the guide wall (320).

[0228] The first tray (300) includes a plurality of tray parts (300a, 300b, 300c), and the plurality of tray parts can be arranged spaced apart in one direction (e.g., left and right direction).

[0229] A water supply unit (240) may be coupled to the upper portion of the above bracket (220). A storage space (241) in which fluid is stored may be formed inside the water supply unit (240).

[0230] The first part of the water supply unit (240) may be located on the outside of the tray assembly and supported by the bracket (220). For example, the first part may form the upper part of the water supply unit (240).

[0231] The second part of the water supply unit (240) is positioned inside the tray assembly to supply fluid to the cell (360). For example, the second part may form the lower part of the water supply unit (240). When the fluid is supplied, the tray assembly may be in the water supply position.

[0232] The above water supply unit (240) may be provided with a discharge unit (243) for discharging fluid. The discharge unit (243) may be formed at an end (e.g., a lower end) of the water supply unit (240). The discharge unit (243) may include a discharge hole for discharging fluid.

[0233] The above water supply unit (240) may be supported on the tray assembly. The portion where the water supply unit (240) is supported on the tray assembly may form a boundary portion between the first portion and the second portion of the water supply unit (240). The second portion of the water supply unit (240) may be located on the inside of the third extension wall (433, see FIG. 7) of the second tray (400).

[0234] At the ice-making position of the tray assembly, the first tray (300) and the second tray (400) can contact each other to form cells (360) corresponding to the desired ice shape.

[0235] 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 (for example, in the circumferential direction) to form the cell (360).

[0236] 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).

[0237] The above diameter (D2) may form the diameter of the opening (313) of the first tray (300). The opening (313) 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 opening (413) of the second tray (400). The opening (413) of the second tray (400) may form an end (e.g., a upper end) of the second tray (400).

[0238] From one perspective, the first tray (300) may be understood to function as a cover member covering the opening of the second tray (400).

[0239] 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).

[0240] When defining the horizontal (X-axis) diameter (D1) and vertical (Z-axis) diameter (D3) of the above cell (360), the diameter (D1) and the diameter (D3) are formed to be the same so that a spherical cell can be implemented.

[0241] As another example, the diameter (D3) may be formed to be larger than the diameter (D1) to implement an elliptical cell having a major axis in one direction (e.g., up and down). By forming the cell in an elliptical shape, the diameter (D1) perpendicular to the moving direction (Z-axis direction) may be formed to be smaller than the diameter (D3) corresponding to the moving direction, thereby reducing the moving torque.

[0242] FIG. 6 is a perspective view showing the configuration of a tray assembly according to a first embodiment of the present invention, FIG. 7 is a perspective view showing the configuration of a second tray according to the first embodiment of the present invention, FIG. 8 is a front view of the second tray, FIG. 9 is a plan view of the second tray, FIG. 10 is a cross-sectional view taken along line 10-10 of FIG. 7, and FIG. 11 is a cross-sectional view taken along line 11-11 of FIG. 6.

[0243] Referring to FIGS. 6 to 11, a tray assembly according to a first embodiment of the present invention may include a first tray (300) and a second tray (400). The first tray (300) may define a first cell (310b) which is a part of a cell (360).

[0244] The first tray (300) may include a first tray wall (310) forming a portion of the cell (360). For example, the first tray wall (310) may define the first cell (310b). The inner surface of the first tray wall (310) forms a first cell surface (310a), and the first cell surface (310a) may be understood to define an outer surface of the first cell (310b).

[0245] The first tray (300) may include a plurality of tray parts (300a, 300b, 300c) each defining a first cell (310b). The plurality of first cells (310b) may be arranged in one direction (for example, in the X-axis direction).

[0246] The first tray (300) may include a first opening (313). The first opening (313) forms an end (e.g., a lower end) of the first tray (300) and may be in contact with the second tray (400).

[0247] The first tray (300) may include a guide wall (320) extending from the first tray wall (310). The guide wall (320) may extend in a direction toward the bracket (220). For example, the guide wall (320) may extend in one direction (e.g., upward) from the first tray wall (310).

[0248] The above guide wall (320) can form a through hole (323). The through hole (323) can be formed to penetrate from the inner surface of the first tray wall (310), i.e., the first cell surface (310a), to the outer surface of the guide wall (320).

[0249] The first end of the above-mentioned through hole (323), i.e., the inlet-side end, may be connected to the first cell surface (310a). The second end of the above-mentioned through hole (323), i.e., the outlet-side end, may be connected to an end (e.g., the upper end) of the above-mentioned guide wall (320). During the ice-making process, air bubbles in the cell (360) are discharged through the through hole (323), thereby preventing an air pocket phenomenon in the cell (360).

[0250] The above guide wall (320) may include a drainage portion (324) that is connected to the through hole (323) and penetrates forward of the guide wall (320). The drainage portion (324) may direct the fluid discharged through the through hole (323) to the outside of the first tray (300) to prevent ice from forming in the through hole (323). For example, the drainage portion (324) may include a drainage hole.

[0251] The guide wall (320) may be formed with a fastening portion (325) to which a fastening member is coupled. The fastening portion (325) may include a fastening groove that is recessed from an end (e.g., an upper end) of the guide wall (320). The fastening member may be coupled to the bracket (220) and / or may be coupled to the fastening portion (325) to couple the first tray (300) to the bracket (220).

[0252] The second tray (400) may define a second cell (410b), which is another part of the cell (360). The second tray (400) may include a second tray wall (410) forming another part of the cell (360). For example, the second tray wall (410) may define the second cell (410b). The second tray wall (410) may be referred to as a "cell wall" forming a cell.

[0253] The inner surface of the second tray wall (410) forms a second cell surface (410a), and the second cell surface (410a) can be understood to define the outer surface of the second cell (410b).

[0254] The second tray (400) may define, for example, a plurality of second cells (410b). The plurality of second cells (410b) may be arranged in one direction (for example, in the X-axis direction). In order to define the plurality of second cells (410b), a plurality of second tray walls (410) may be provided, and each second tray wall (410) may be arranged in one direction (for example, in the X-axis direction).

[0255] The second tray (400) forms an end (e.g., an upper end) of the second tray (400) and may include a second opening (413) that contacts the first tray (300).

[0256] The second tray (400) may include a first extension wall (420) extending in a first direction (for example, horizontally) toward the outside of the second tray wall (410). The first extension wall (420) may be mounted on the third wall (453) of the second tray supporter (450).

[0257] A plurality of second tray walls (410) defining the plurality of second cells (410b) are provided, and the first extension wall (420) may extend outside the plurality of second tray walls (410). For example, the first extension wall (420) may include a square-shaped flat wall.

[0258] The first extension wall (420) may be formed at a location where an extension line in a first direction (for example, a horizontal direction) that bisects the height of the cell (360) in a second direction (for example, an up-down direction) passes. When defining the center (C1) of the cell (360), an extension line in the first direction (for example, a horizontal direction) that passes through the center (C1) may pass through the first extension wall (420).

[0259] 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).

[0260] The end (e.g., the lower end) of the first part (411) may form a recessed portion (411a). As water expands during the ice-making process, the recessed portion (411a) may be deformed (expanded) into a desired cell shape.

[0261] The above first part (411) can be accommodated in the accommodation space (453a) of the second tray supporter (450) and supported by the second tray supporter (450).

[0262] 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) based on the first extension wall (420). The second part (412) may form a part of another area (e.g., upper area) of the cell (360).

[0263] An end (e.g., an upper end) of the second part (412) may form the opening (413). The second part (412) may be understood as a portion that is not accommodated in the accommodation space (453a).

[0264] The first part (411) and the second part (412) may be formed integrally. As another example, the first part (411) and the second part (412) may be manufactured separately and then assembled.

[0265] By means of the second part (412), the second tray (400) can extend to a position higher than the center (C1) of the cell (360) by a first height (△) (see FIG. 5). With this configuration, the size of the portion where ice is deformed into an undesirable shape due to water leakage between the first tray (300) and the second tray (400) can be reduced. By reducing the size of the first tray (300), the degree of ice adhesion to the first tray (300) can be reduced.

[0266] The second tray wall (410) may include a plurality of portions having different degrees of internal deformation. The plurality of portions may include a first portion (412a) having a first degree of internal deformation and a second portion (412b) having a second degree of internal deformation.

[0267] The internal deformation of the first portion (412a) may be greater than the internal deformation of the second portion (412b). For example, the first thickness (t1) of the first portion (412a) may be greater than the second thickness (t2) of the second portion (412b).

[0268] The first part (412a) may be formed on the second part (412) of the second tray wall (410). The second part (412b) may be formed on the second part (412) of the second tray wall (410).

[0269] Since the first part (411) of the second tray wall (410) is supported by the second tray supporter (450), a desired ice shape can be implemented during the process of fluid expansion during ice making. However, the second part (412) of the second tray wall (410) may protrude to one side (e.g., the upper side) of the second tray supporter (450) and may not be directly supported by the second tray supporter (450). Therefore, it may not be easy to implement a desired ice shape during the process of fluid expansion during ice making.

[0270] To solve this problem, the first part (412a) and the second part (412b) can be configured so that the part of the second part (412) adjacent to the first extension wall (420) undergoes relatively little deformation, and the part far from the first extension wall (420) undergoes relatively much deformation.

[0271] The first portion (412a) forms a portion adjacent to the first extension wall (420) and may have a relatively large first thickness (t1). The portion adjacent to the first extension wall (420) may be understood as a portion adjacent to the center (C1) of the cell (360) forming the diameter (D1) of the ice. The first portion (412a) may be understood as a portion adjacent to an extension line passing through the center (C1) of the cell (360) in a first direction (e.g., horizontal direction).

[0272] The second portion (412b) forms a portion that is relatively far from the first extension wall (420) and may have a second thickness (t2) that is relatively small. The portion that is relatively far from the first extension wall (420) may be understood as a portion that is far from the center (C1) of the cell (360) that forms the diameter (D1) of the ice.

[0273] The second part (412b) may be understood as a part adjacent to the opening (413) of the second tray (400). In this way, a part of the second part (412) close to the center of the ice among the cells (360) may have a large degree of internal deformation or a large thickness, thereby reducing the amount of deformation during the ice separation process.

[0274] Meanwhile, other parts of the second part (412) farther from the center of the ice among the cells (360) can be made to have a small degree of deformation or a small thickness, thereby increasing the deformation amount during the ice separation process. With this configuration, when the second opening (413) of the second tray (400) expands during the ice separation process and ice is discharged, the deformation amount in the part adjacent to the second opening (413) increases, making ice separation easier.

[0275] The second part (412) may be configured so that the size of the second part (412b) having the second thickness (t2) increases from the first extension wall (420) toward the second opening (413).

[0276] For example, a plurality of first parts (412a) having a first thickness (t1) may be provided spaced apart in one direction (for example, in the circumferential direction), and a second part (412b) may be provided between the plurality of first parts (412a). The area of ​​the second part (412b) may increase in one direction (for example, upward) toward the second opening (413). With this configuration, the expansion rate of the second part (412) can be evenly maintained in one direction (for example, in the circumferential direction) during the ice-making process.

[0277] The second tray (400) may include a second extension wall (431) extending in one direction (e.g., upward) from the second part (412). For example, the thickness (t3) of the second extension wall (431) may be formed to be the same as or at the same level as the thickness of the second part (412b).

[0278] In order to reinforce the thin thickness of the second portion (412b) and the second extension wall (431), the second tray (400) may include a reinforcing rib (436). The reinforcing rib (436) may be provided on the outer surface of at least one of the second portion (412b) and the second extension wall (431).

[0279] The second tray (400) may include a third extension wall (433) that forms a flow path for the fluid supplied to the cell (360). The third extension wall (433) may extend outward from the second part (412), for example, upward.

[0280] The thickness (t4) of the third extension wall (433) may be formed to be greater than the thickness of the second portion (412b) and the second extension wall (431) so as not to be easily deformed by fluid.

[0281] 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 the end (e.g., an upper end) of the second tray wall (410).

[0282] As another example, the peripheral wall (430) may be formed separately from the second tray wall (410) and positioned around an end (e.g., an upper end) of the second tray wall (410). In this case, the peripheral wall (430) may be in contact with the second tray wall (410) or may be spaced apart from the second tray wall (410). In either case, the peripheral wall (430) may surround at least a portion of the first tray (300).

[0283] If the second tray (400) includes the peripheral wall (430), the second tray (400) can surround the first tray (300).

[0284] The space between the peripheral wall (430) and the first tray (300) can form a fluid flow space when water is supplied from the water supply unit (240). The space between the peripheral wall (430) and the first tray (300) can form a storage space for the discharged fluid when the fluid is discharged through the drain unit (324) of the first tray (300).

[0285] The above-mentioned peripheral wall (430) may include a second extension wall (431) extending in one direction (e.g., in the vertical direction) along the perimeter of the end (e.g., the upper end) of the second part (412). The second extension wall (431) may be arranged to surround at least a portion of the first tray (300).

[0286] A portion of the inner surface of the second extension wall (431) may contact the first tray (300). At least a portion of the outer surface of the first tray wall (310) may form a first contact surface (312a) that contacts the second extension wall (431).

[0287] The second extension wall (431) may extend in an inclined or rounded manner in a direction away from the first tray (300). The inclined or rounded portion may form a contact surface (431a) that contacts the first contact surface (312a).

[0288] The above contact surface (431a) can be extended to be inclined at a set angle (θ) with respect to one direction (e.g., the X-axis direction). That is, the above contact surface (431a) can form an inclined contact surface.

[0289] The height of the part where the first contact surface (312a) of the first tray (300) and the second extension wall (431) come into contact can be formed at a position lower by a second height (△) than the height of the drainage part (324) of the first tray (300) (see FIG. 5). Accordingly, the fluid discharged through the drainage part (324) can be easily stored in the space between the first tray (300) and the peripheral wall (430).

[0290] The second extension wall (431) can reduce the heat transferred from the transparent ice heater (490) to the second tray (400) from being transferred to the first cell (310b) formed by the first tray (300). That is, the second extension wall (431) serves to move the heat conduction path away from the first cell (310b).

[0291] The second extension wall (431) can extend to a position that is higher by a third height (△) than the drainage portion (324) of the first tray (310) (see FIG. 5). That is, the end portion (e.g., the upper portion (431b)) of the second extension wall (431) can be formed at a position that is higher by a third height (△) than the drainage portion (324). According to this configuration, it is possible to prevent water (supercharged water) discharged through the drainage portion (324) from leaking out of the second tray (400) beyond the second extension wall (431).

[0292] The above second extension walls (431) may be provided at each end (e.g., the upper end) of a plurality of second tray walls (410). The plurality of second extension walls (431) may be spaced apart from each other in the X-axis direction.

[0293] The second tray (400) may include a separation wall (432) provided between the plurality of second extension walls (431). The separation wall (432) may connect the rear ends of the plurality of second extension walls (431). By the separation wall (432), the plurality of second extension walls (431) may be spaced apart from each other.

[0294] The second tray (400) may include a plurality of tray parts defining a plurality of cells. For example, as illustrated in FIG. 7, the plurality of tray parts may include a first tray part (401a) defining a first cell, a second tray part (401b) defining a second cell, and a third tray part (401c) defining a third cell.

[0295] The first tray part (401a) may be a part that forms a central cell among a plurality of cells, and the second and third tray parts (401b, 401c) may be parts that form cells on both sides among a plurality of cells.

[0296] The above-described separating wall (432) may be provided in multiple numbers. For example, the separating wall (432) may include a first separating wall (432a) provided between the second extension wall (431) of the first tray part (401a) and the second extension wall (431) of the second tray part (401b). The separating wall (432) may include a second separating wall (432b) provided between the first extension wall (431) of the second tray part (401b) and the second extension wall (431) of the third tray part (401c).

[0297] The second tray (400) may include a third extension wall (433) disposed on a portion (e.g., a rear portion) of the first tray (300). The second extension wall (431) and the third extension wall (433) may be disposed opposite each other with respect to the center of the cell. For example, the second extension wall (431) may be disposed on a portion (e.g., a rear portion) of the first tray (300), and the third extension wall (433) may be provided on the opposite side of the second extension wall (431).

[0298] At least a portion of the third extension wall (433) may guide the flow or form a flow path when water is supplied from the water supply unit (240) to the cell (360). The third extension wall (433) may extend in one direction (e.g., upward) from the second tray wall (410). The third extension wall (433) may extend in the other direction (e.g., forward) from the second tray wall (410) and may be configured to have a “ㄷ” shape by bending laterally.

[0299] The second tray (400) may include a plurality of cells. For example, the second tray (400) may include three cells. However, the number of cells may not be limited thereto. The first cell may be positioned between the second cell and the third cell so that the fluid discharged from the first cell flows into the second cell and the third cell.

[0300] The above extension wall (433) may be connected to the second cell wall forming the second cell and the third cell wall forming the third cell. The third extension wall (433) may be formed to have a step in one direction (e.g., in the vertical direction). For example, the third extension wall (433) may include a first part (433a) extending in one direction (e.g., upward) from the opening (413) of the second tray wall (410) forming the opening (413).

[0301] The first part (433a) may form a contact surface that comes into contact with the first tray (300). The first tray (300) may form a second contact surface (312b) that comes into contact with the first part (433a). The second contact surface (312b) may form a contact surface in one direction (e.g., in the up-down direction).

[0302] The third extension wall (433) may include a second part (433b) that extends in one direction (e.g., upward) at a set angle (θo) from the first part (433a). The second part (433b) may extend in a direction away from the first tray (300).

[0303] The third extension wall (433) may include a third part (433c) extending in one direction (e.g., upward) from the second part (433b). A space defining a fluid flow path may be formed inside the third extension wall (433).

[0304] The above water supply unit (240) may include a portion located on the inner side of the third extension wall (433). The fluid of the above water supply unit (240) may be discharged from the inner space of the third extension wall (433) and fall onto the first tray (300).

[0305] The first tray (300) may include a guide surface (311, see FIG. 12) that comes into contact with the fluid during the water supply process. The fluid discharged from the water supply unit (240) may fall onto the guide surface (311).

[0306] The first tray (300) may include a water supply guide (327) provided on at least one side of the guide surface (311). The water supply guide (327) protrudes from the first tray wall (310) of the first tray (300) and may prevent fluid from leaking out of the guide surface (311). For example, the water supply guide (327) may include a protruding rib.

[0307] The above water supply guide (327) may protrude from at least one side of the guide surface (311). That is, the guide surface (311) may be understood as a surface defined between the water supply guides (327) on both sides of the outer surface of the first tray wall (310).

[0308] The above water supply guide (327) may extend from the guide wall (320) in a direction toward the third extension wall (433). A space in which a fluid is stored or a space in which a fluid flows may be formed between the third extension wall (433) and the water supply guide (327).

[0309] The second tray (400) includes a connecting wall (434) connecting the second extension wall (431) and the third extension wall (433), and the connecting wall (434) can extend roundly or slanted in one direction (e.g., rearward) from the second extension wall (431) toward the third extension wall (433).

[0310] The above connecting wall (434) may be provided on both sides of the second tray (400). In a broad sense, the connecting wall (434) may be understood as a part of the second extension wall (431). In this case, the second extension wall (431) may be understood as being connected to the third extension wall (433).

[0311] One end of the third extension wall (433) may be connected to the second tray part (401b), and the other end may be connected to the third tray part (401c). For example, both ends of the third extension wall (433) may be connected to the second extension wall (431) of the second tray part (401b) and the second extension wall (431) of the third tray part (401c).

[0312] When defining the first width (W1) of the first to third tray parts (401a, 401b, 401c) based on the arrangement direction of the first to third tray parts (401a, 401b, 401c), the second width (W2) of the third extension wall (433) may be smaller than the first width (W1). The second width (W2) of the third extension wall (433) may be larger than the diameter (D1) of the cell (360).

[0313] The above second extension wall (431), separation wall (432), connection wall (434), and third extension wall (433) can define a space in which the first tray (300) is located. The space can form a space (channel) in which fluid flows or is stored during the water supply process.

[0314] The second tray (400) may include a reinforcing rib (436) to reinforce the strength of the second tray (400). The reinforcing rib (436) may be provided on the second tray wall (410) or the peripheral wall (430).

[0315] The second tray (400) may be made of a flexible material. The reinforcing rib (436) may prevent undesirable deformation from occurring when water is supplied to the second tray (400) or during the process of moving to an ice-making position (or ice-making position). For example, the reinforcing rib (436) may be provided on at least one wall among the second extension wall (431) and the separation wall (432). The reinforcing rib (436) may be arranged on the surface of the at least one wall so as to extend in one direction (e.g., in the vertical direction).

[0316] The above reinforcing rib (436) may be provided at a relatively weak location in the second tray (400) to prevent undesirable expansion or deformation from occurring during the ice-making process. For example, at least a portion of the reinforcing rib (436) may be placed in the second tray wall (410), particularly in the second part (412b) having the second thickness (t2) among the second part (412).

[0318] Referring to FIGS. 12 to 17, the first tray (300) according to the first embodiment of the present invention may include a plurality of tray parts (300a, 300b, 300c). The plurality of tray parts (300a, 300b, 300c) may be composed of separate parts.

[0319] For example, the plurality of tray parts (300a, 300b, 300c) may include a first tray part (300a) provided in the central portion and second and third tray parts (300b, 300c) provided on both sides of the first tray part (300a).

[0320] The first tray (300) may include a first tray wall (310) forming a first cell (310b). The inner circumferential surface of the first tray wall (310) may form a first cell surface (310a). For example, the first cell surface (310a) may include a rounded surface to form a portion of a cell (360).

[0321] The first tray (300) may include a guide wall (320) extending or protruding from the first tray wall (300). The guide wall (320) may extend in one direction (e.g., upward) from the first tray wall (310) and be fastened to the bracket (220).

[0322] The above guide wall (320) may include a through hole (323) through which air of the cell (360) is discharged during the ice-making process. The through hole (323) may be formed penetrating from one end (e.g., the lower end) of the guide wall (320) to the other end (e.g., the upper end). The through hole (323) and the fastening groove (325) may be arranged in one direction (e.g., the X-axis direction).

[0323] The above guide wall (320) may include a drainage portion (324) that is fluidly connected to the through hole (323) and allows the fluid discharged through the through hole (323) to be drained to the outside of the guide wall (320). The drainage portion (324) may be formed to penetrate from the through hole (323) to one surface (e.g., the front) of the guide wall (320).

[0324] Define the direction. The forward direction of the guide wall (320) can be understood as the direction in which the water supply unit (240) is located based on the guide wall (320). From the perspective of the overall structure of the tray assembly, the forward direction can be understood as the direction in which the water supply unit (240) is located based on the center (C1) of the cell (360), and the rear direction can be understood as the direction in which the shaft (520) is located.

[0325] The first tray (300) may include a guide surface (311) that guides the fluid so that the surface discharged from the drainage portion (324) can flow down the first tray wall (310). The guide surface (311) may form a portion of the outer circumference of the first tray wall (310). The guide surface (311) may extend forward from the drainage portion (324).

[0326] The first tray (300) may include a water supply guide (327) that prevents fluid from splashing out of the guide surface (311). The water supply guide (327) may protrude in one direction (e.g., upward) from the first tray wall (310).

[0327] The above water supply guide (327) is provided in multiple numbers, and the multiple water supply guides (327) may be provided on both sides of the drainage unit (324). The multiple water supply guides (327) may include a first water supply guide (327a) provided on one side of the drainage unit (324) and a second water supply guide (327b) provided on the other side of the drainage unit (324). The guide surface (311) may be formed between the first and second water supply guides (327a, 327b).

[0328] The first and second water supply guides (327a, 327b) are provided in the first tray part (300a), and may not be provided in the second and third tray parts (300b, 300c). This may be due to the structural feature that the water supply unit (324) is arranged on one side (e.g., the upper side) of the first tray part (300a).

[0329] The fluid discharged from the above-mentioned water supply unit (324) may fall from (for example, the upper side) of the first tray part (300a) to the guide surface (311) and flow into a plurality of cells (360). Specifically, the fluid may flow in one direction (for example, downward) from the guide surface (311) and flow into the cell (360), i.e., the central cell, defined by the first tray part (300a). In this process, the first and second water supply guides (327a, 327b) may guide the fluid falling to the guide surface (311) to flow into the central cell defined by the first tray part (300a).

[0330] After the fluid flows into the central cell, the additional fluid can flow in one direction (e.g., left and right) through the third extension wall (433) and flow into the first lateral cell (e.g., left cell) and the second lateral cell (e.g., right cell). The first lateral cell may be a cell (360) defined by the second tray part (300b), and the second lateral cell may be a cell (360) defined by the third tray part (300c).

[0331] The above water supply unit (240) may include a water supply wall (242) forming a storage space (241). The water supply wall (242) includes a wall that is closed in the circumferential direction so as to store fluid, and the wall may include a plurality of walls that extend and are bent in the circumferential direction so as to have a cup shape.

[0332] The above water supply unit (240) may include a discharge unit (243) extending to one side (e.g., downward) of the water supply wall (242). The length of one end (e.g., front end) of the discharge unit (243) may be formed to be longer than the length of the other end (e.g., rear end). That is, the discharge unit (243) may extend downwardly from the other end (e.g., rear end) toward one end (e.g., front end).

[0333] The first tray wall (310) may extend downward from the center of one end (e.g., the upper end) to the outer circumference of the other end (e.g., the lower end). In response to the shape of the first tray wall (310), the lengths of one end (e.g., the front end) and the other end (e.g., the rear end) of the discharge portion (243) may be configured to be different, thereby making the distance between the discharge portion (243) and the first tray wall (310) constant. Accordingly, the phenomenon of water splashing during the water supply process can be prevented.

[0334] For example, the discharge portion (243) may include a first discharge wall (243a) forming a wall of one end (e.g., a front end) of the discharge portion (243). The discharge portion (243) may include two second discharge walls (243b) forming side walls of the discharge portion (243). The discharge portion (243) may include a third discharge wall (243c) forming a wall of the other end (e.g., a rear end) of the discharge portion (243).

[0335] The length of the first discharge wall (243a) may be formed to be longer than the length of the third discharge wall (243c). The discharge end (243d) of the discharge portion (243) may be formed to be inclined between the first discharge wall (243a) and the third discharge wall (243c).

[0336] The discharge portion (243) may overlap with the guide surface (311) of the first tray (300) in one direction (e.g., in the vertical direction). Accordingly, the fluid discharged from the discharge portion (243) may fall onto the guide surface (311) and flow down along the guide surface (311) to one side (e.g., downward) of the first tray (300).

[0337] At the water supply position of the tray assembly, the second tray (400) may be moved in a direction where the contact with the first tray (300) is partially released and the distance from the first tray (300) increases. For example, the second tray (400) may be moved in a direction where the contact is released while the third extension wall (433) is in contact with the second contact surface (312b).

[0338] The second tray (400) can move in the positive direction by a set angle (θ2) based on the shaft (520). As the second tray (400) moves, the fluid falling along the guide surface (311) can flow into the central cell among the plurality of cells (360) through the space between the third extension wall (433) and the second contact surface (312b) of the first tray (300).

[0339] The supplied fluid may be first supplied to the central cell, and after filling the interior of the central cell, the fluid may flow into the first and second lateral cells on both sides. After filling the interior of the second tray (400) defining the central cell, the additionally supplied fluid may be supplied (water spread) by branching to the first and second lateral cells along the water supply path (435).

[0340] The above water supply path (435) may be formed on one side (e.g., the upper side) of the second tray wall (410). The above water supply path (435) may be formed between the second extension wall (431) and the third extension wall (433). The above water supply path (435) may be formed in the inner space of the third extension wall (433).

[0341] The above water supply path (435) may be formed in at least a portion of the first to third parts (433a, 433b, 433c) of the third extension wall (433). The above water supply path (435) may include a first water supply path extending from the central cell to the first lateral cell and a second water supply path extending from the central cell to the second lateral cell.

[0342] Figures 18 to 21 are drawings showing ice making, ice removal, and water supply in an ice maker according to a first embodiment of the present invention.

[0343] Fig. 18 is a drawing showing how ice is made in an ice maker according to a first embodiment of the present invention. When ice making is completed at the ice making positions of the first and second tray assemblies, ice (I) is created, and the second tray assembly can be moved to the ice removal position as shown in Fig. 19.

[0344] The direction in which the second tray assembly moves from the ice-making position of Fig. 18 to the ice-breaking position of Fig. 19 may be referred to as forward movement (or forward rotation). On the other hand, the direction in which the second tray assembly moves from the ice-making position of Fig. 19 to the ice-breaking position of Fig. 18 may be referred to as reverse movement (or reverse rotation).

[0345] Fig. 19 shows the position where the ice-breaking begins. 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). 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.

[0346] Additional embodiments may be proposed to facilitate separation of the ice and the first tray (300). For example, in order to reduce the contact area between the ice and the first tray (300), small protrusions may be added to the inner first cell surface (310a) of the first tray (300) to reduce the adhesion area between the ice and the first tray (300). As another example, the material of the first tray (300) may be configured with a flexible or ductile material to reduce ice adhesion. As yet another example, a coating capable of reducing ice adhesion may be provided on the first cell surface (310a). As yet another example, a heat source (heater) may be added to the first tray wall (310) of the first tray (300) to melt the ice surface and reduce ice adhesion.

[0347] FIG. 20 shows a state in which the second tray assembly in FIG. 19 moves more forward, and the second tray (400) is pressed by the pusher (540) and moves to the maximum pressing position of the pusher (540). As the pusher (540) presses the end (e.g., the bottom) of the second tray (400), ice may begin to separate from the second tray (400).

[0348] In the process of separating the ice from the second tray (400), the second tray (400) may be deformed in a direction in which the diameter of the opening (413) expands. For this purpose, the second tray (400) may be made of, for example, a flexible or malleable material. In this process, the ice may be completely separated from the second tray (400) and stored in the ice bin (60). In order to increase the reliability of the separating operation, the separating operation of FIGS. 19 and 20 may be performed repeatedly a set number of times or more.

[0349] Once the ice-making operation is completed, the second tray assembly can move in the reverse direction and return to the ice-making position as shown in FIG. 18. When the water supply operation starts at the ice-making position, the second tray assembly can move in the forward direction toward the water supply position as shown in FIG. 21. At the water supply position, the material (M) is supplied through the water supply unit (240), and the fluid can be supplied to a plurality of cells (360).

[0350] Once the water supply is complete, the second tray assembly can move backward to the ice-making position and perform an ice-making operation. During the ice-making process, cold is supplied to the ice maker, and the transparent ice heater (490) operates to produce transparent ice. Meanwhile, during ice-making, the transparent heater (490) can be turned off for a set period of time and then left on standby so that ice can be frozen at the bottom of the cell (360).

[0351] Hereinafter, other embodiments of the present invention will be described. Since these other embodiments differ in some configurations from the first embodiment, the description will focus on the differences, and for parts that are identical to those of the first embodiment, the description and drawing references of the first embodiment will be used.

[0352] Figure 22 is an exploded perspective view of an ice maker according to a second embodiment of the present invention.

[0353] Referring to FIG. 22, an ice maker (200a) according to a second embodiment of the present invention may include a first tray (600) forming at least a portion of a cell (360). The ice maker (200a) may include a second tray (400a) forming another portion of the cell (360). A plurality of cells (360) may be defined by the first tray (600) and the second tray (400a).

[0354] The first tray (600) may include a plurality of tray parts (600a, 600b, 600c). The number of the plurality of tray parts (600a, 600b, 600c) may correspond to the number of the plurality of cells (360).

[0355] The above ice maker (200a) may include a second tray cover (480a) and a second tray supporter (450a). A second tray (400a) may be placed between the second tray cover (480a) and the second tray supporter (450a). The second tray cover (480a), the second tray (400a), and the second tray supporter (450a) may be coupled to each other and move as one unit.

[0356] At least a portion of the second tray cover (480a) may be positioned on one side (e.g., the upper side) of the second tray (400). The second tray cover (480a) may include a cover wall (481) forming an opening (482). The cover wall (481) may be positioned on one side (e.g., the upper side) of the first extension wall (420) of the second tray (400a).

[0357] The first extension wall (420) may include a tray protrusion (429) that comes into contact with the second tray cover (480a). A plurality of the tray protrusions (429) may be provided at the corners of the first extension wall (420).

[0358] The second tray cover (480a) 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).

[0359] A protrusion (562) of a lift (560) may come into contact with one surface (e.g., a bottom surface) of the first extension wall (420). When the lift (560) moves further, the protrusion (562) presses the first extension wall (420) in one direction (e.g., upward), and in this process, the tray protrusion (429) or the first extension wall (420) may be deformed.

[0360] The above lift (560) can be understood 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 (600).

[0361] 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 (400a). The tray protrusion (427a) may protrude in one direction (e.g., upward) from the first extension wall (420).

[0362] The second tray cover (480a) is formed to penetrate the cover wall (481), and a guide groove (481b) that accommodates the tray protrusion (427a) can be formed. The assembly of the second tray (400a) and the second tray cover (480a) can be guided through the guide groove (481b).

[0363] The second tray cover (480a) may be provided on the cover wall (481) and may include a moving guide (487) that helps move ice during the moving process. The moving guide (487) may be provided on a part (e.g., a rear portion) of the cover wall (481).

[0364] The above-mentioned moving guide (487) can pressurize the ice to separate it from the first tray (600) when the ice is attached to the first tray (600) during the moving process.

[0365] At least a portion of the second tray supporter (450a) may be positioned on one side (e.g., the lower side) of the second tray (400a). The second tray supporter (450a) may support the second tray (400a) on one side (e.g., the lower side) of the second tray (400a). For example, at least a portion of a wall forming a second cell of the second tray (400a) may be supported by the second tray supporter (450a).

[0366] The above ice maker (200a) may include a heater (490, 495).

[0367] The above heater (490, 495) is disposed in the sunken receiving space (453a, see FIG. 3) of the second tray supporter (450a) and may include a transparent ice heater (490) for applying heat to the second tray (400a) during the ice-making process. The transparent ice heater (490) may be disposed adjacent to or in contact with one side (e.g., the lower side) of the second tray (400a) so as to supply heat to a portion (e.g., the lower side) of the second tray (400a).

[0368] The above heater (490, 495) may include an ice 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 ice heater (495) is positioned adjacent to the first tray (600) and may be, for example, a wire-type heater.

[0369] For example, the moving heater (495) may be positioned so as to be in contact with the first tray (600) or may be positioned at a predetermined distance from the first tray (600). In either case, the moving heater (495) may supply heat to the first tray (600), and the heat supplied to the first tray (600) may be transferred to the cell (360).

[0370] The above lift (560) is coupled to the shaft (520) or holder (531, 532). The lift (560) may be provided on at least one side of the shaft (520). For example, a plurality of lifts (560) may be provided on both sides of the shaft (520). The plurality of lifts (560) may be located on both side walls of the second tray supporter (450a).

[0371] The lift (560) may include a support bar (561) that supports a portion (e.g., a lower portion) of the second tray (400a). The support bar (561) may be positioned on the outer side of the side wall of the second tray supporter (450a). The lift (560) may include an extension portion (563) that is coupled to the holder (531, 532). The extension portion (563) may form a through hole (564) into which the holder (531, 532) is inserted.

[0372] The above lift (560) may include a protrusion (562) protruding from the support bar (561) in a direction toward the second tray (400a). The protrusion (562) may press one surface (e.g., the bottom surface) of the tray protrusion (429) of the second tray (400a) to bring the second tray (400) into close contact with the first tray (600).

[0373] At the ice-making position of the tray assembly, the lift (560) can move further in one direction (e.g., upward) based on the axis of the shaft (520) so that the second tray (400a) is pressed against the first tray (600). In this process, the protrusion (562) provides a force toward the first tray (600) to the second tray (400a) through the tray protrusion (429), and the second tray (400a) can transmit a force to press against the second tray cover (480a) in one direction (e.g., upward).

[0374] Fig. 23 is a cross-sectional view showing the configuration of an ice maker according to a second embodiment of the present invention, and Fig. 24 is a cross-sectional view showing how water is supplied in an ice maker according to a second embodiment of the present invention.

[0375] Referring to FIGS. 23 and 24, the first tray (600) according to the second embodiment of the present invention may include a guide wall. The guide wall may extend in one direction (e.g., upward) toward the bracket (220a).

[0376] The above guide wall can form a through hole (615a). The through hole (615a) can be formed to penetrate from the inner surface of the wall of the first tray (600), i.e., the first cell surface (610a), to the outer surface of the guide wall.

[0377] The first end of the above-mentioned through hole (615a), i.e., the inlet end, may be connected to the first cell surface (610a), and the second end of the above-mentioned through hole (615a), i.e., the outlet end, may be connected to an end (e.g., the upper end) of the guide wall. During the ice-making process, air bubbles in the cell (360) may be discharged through the through hole (615a), thereby preventing an air pocket phenomenon in the cell (360).

[0378] The above guide wall may include a drainage portion (615b) that is connected to the through hole (615a) and penetrates one side (e.g., the front) of the guide wall. The drainage portion (615b) may direct the fluid discharged through the through hole (615a) to the outside of the first tray (600) to prevent ice from forming in the through hole (615a). One side (e.g., the bottom side) of the drainage portion (615b) may extend inclinedly toward the side of the through hole (615a).

[0379] The first tray (600) may be formed with a fastening groove (616a) into which a fastening member is coupled. The fastening member may be coupled to the bracket (220a) and fastened to the fastening groove (616a), thereby coupling the first tray (600) to the bracket (220a).

[0380] The water supply unit (240) that supplies fluid to the above cell (360) can be coupled to the bracket (220a). The discharge unit (243) of the water supply unit (240) can be located on the inside of the third extension wall (433) of the second tray (400a).

[0381] The discharge end of the above discharge portion (243) may overlap with at least a portion of the third extension wall (433) in one direction (e.g., in the vertical direction). Accordingly, the fluid discharged from the discharge end may fall onto the third extension wall (433).

[0382] Since the moving heater (495) is arranged on the first tray (600), unlike the first embodiment, in this embodiment, the supplied water is supplied to the third extension wall (433), thereby preventing the water from being supplied to the moving heater (495). For example, the discharge end overlaps the second part (433b) of the third extension wall (433), and the fluid discharged from the discharge end can contact the second part (433b).

[0383] The length of one end (e.g., rear end) of the discharge portion (243) may be formed to be longer than the length of the other end (e.g., front end). That is, the discharge portion (243) may extend downwardly from the other end (e.g., front end) toward one end (e.g., rear end).

[0384] The second part (433b) may extend obliquely toward one side (e.g., rearward). In response to the shape of the second part (433b), the lengths of the other end (e.g., front end) and one end (e.g., rear end) of the discharge portion (243) may be configured differently, thereby making the distance between the discharge portion (243) and the second part (433b) constant. Accordingly, the phenomenon of water splashing during the water supply process can be prevented. For example, the length of the third discharge wall (243c) forming the first wall (e.g., rear end wall) of the discharge portion (243) may be formed longer than the length of the first discharge portion (243a) forming the second wall (e.g., front end wall).

[0385] At the water supply position of the tray assembly, the second tray (400a) can be moved in a direction away from the first tray (600) by partially releasing the contact state with the first tray (600). The second tray (400) can be moved in the positive direction by a set angle based on the shaft (520).

[0386] As the second tray (400) moves, the fluid that has fallen into the second part (433b) can be guided to flow into the central cell defined by the first tray part (600a). The supplied fluid can be first supplied to the central cell, and after filling the interior of the central cell, the fluid can flow into the first and second lateral cells on both sides.

[0387] Figure 25 is an exploded perspective view of an ice maker according to a third embodiment of the present invention.

[0388] Referring to FIG. 25, an ice maker (200b) according to a third embodiment of the present invention may include a first tray (700) forming at least a portion of a cell (360). The ice maker (200b) may include a second tray (400b) forming another portion of the cell (360).

[0389] The first tray (700) may include a plurality of tray parts (700a, 700b, 700c). The number of the plurality of tray parts (700a, 700b, b00c) may correspond to the number of the plurality of cells (360).

[0390] 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 (480b) and the second tray supporter (450b) may refer to the contents described in the previous embodiment.

[0391] Fig. 26 is a cross-sectional view showing the configuration of an ice maker according to a third embodiment of the present invention.

[0392] Referring to FIG. 26, a first tray (700) according to a third embodiment of the present invention may include a guide wall. The guide wall may form a through hole (715a). The guide wall may include a drainage portion (715b) connected to the through hole (715a) and penetrating into one side (e.g., the front) of the guide wall.

[0393] The first tray (700) above may be formed with a fastening groove (716) into which a fastening member is coupled. The description of the through hole (715a), the drainage portion (715b), and the fastening groove (716) refers to the description of the through hole (615a), the drainage portion (615b), and the fastening groove (616a) described in the previous embodiment.

[0394] A first opening formed at one end (e.g., the bottom) of the first tray (700) may be in contact with a second opening formed at the other end (e.g., the top) of the second tray (400b). In other words, a portion of the first tray (700) forming the first opening may be in contact with a portion of the second tray wall (410) forming the second opening.

[0395] The portion where the first tray wall (710) and the second tray wall (410) come into contact may be formed lower than the through hole (715a). Accordingly, air discharge from the cell (360) can be easily achieved through the through hole (715a) located relatively on one side (e.g., the upper side).

[0396] The water supply unit (240) that supplies fluid to the above cell (360) can be coupled to the bracket (220). The discharge unit (243) of the water supply unit (240) can be located on the inside of the third extension wall (1433) of the second tray (400b).

[0397] An end (e.g., a lower end) defining a first opening of the first tray (700) may include a first contact end (719) that contacts the second tray (400b). The first contact end (719) may extend in one direction (e.g., in a circumferential direction) and form a border of the first opening (710c). For example, the first contact end (719) may have a ring shape.

[0398] The first tray (700) includes a second extension wall (714) extending in one direction (for example, upward) from the first contact end (719), and an end (714a) of the second extension wall (714) may be positioned higher than an end (431b) of the second extension wall (431) of the second tray (400b) with respect to a point of the first tray or the second tray.

[0399] The second extension wall (714) of the first tray (700) and the second extension wall (431) of the second tray (400b) can extend in one direction (for example, upward) from the contact portion of the first and second trays (700, 400b).

[0400] The gap between the second extension wall (714) and the second extension wall (431) may be formed to gradually increase in one direction (e.g., upward). That is, the upper gap (△) between the second extension wall (714) and the second extension wall (431) T) is the lower spacing (△ B ) may be larger. According to this configuration, interference between the first and second trays (700, 400b) can be avoided when returning to the ice-making position after the ice-making operation of the second tray (400b).

[0401] FIG. 27 is a perspective view showing the configuration of a tray assembly according to a third embodiment of the present invention, FIG. 28 is a perspective view showing the configuration of a second tray according to a third embodiment of the present invention, FIG. 29 is a front view of the second tray, FIG. 30 is a plan view of the second tray, FIG. 31 is a cross-sectional view taken along line 31-31 of FIG. 28, and FIG. 32 is a cross-sectional view taken along line 32-32 of FIG. 27.

[0402] Referring to FIGS. 27 to 32, a second tray (400b) according to a third embodiment of the present invention may include a second tray wall (410). The second tray wall (410) includes a first part (411) positioned on one side (e.g., lower side) of the first extension wall (420) with respect to the first extension wall (420), and the first part (411) may form one area (e.g., lower area) of the cell (360).

[0403] The second tray wall (410) may include a second part (412) positioned above the first extension wall (420) based on the first extension wall (420). The second part (412) may form a part of another region (e.g., an upper region) of the cell (360).

[0404] The second part (412) may include a second contact end portion (412c) that comes into contact with the first tray (700). The second contact end portion (412c) may come into contact with the first contact end portion (719) of the first tray (700). The second contact end portion (412c) may include a portion that protrudes radially from the inner circumferential surface of the second part (412) and on which the first contact end portion (719) is seated.

[0405] The second contact end (412c) may be formed in an area where the second part (412) and the third extension wall (433) meet. For example, the second contact end (412c) may have a ring shape. The contact surface where the first contact end (719) and the second contact end (412c) come into contact may include a first surface (e.g., a horizontal surface).

[0406] The second extension wall (420) may include a fastening groove (425a) that is sunken into one end (e.g., a front end) of the second extension wall (420). A plurality of the fastening grooves (425a) may be formed spaced apart from each other in the left and right directions.

[0407] The second extension wall (420) may include a fastening hole (425b) formed in a portion (e.g., a rear portion) of the second extension wall (420). The fastening holes (425b) may be formed in multiple numbers spaced apart from each other in the left-right direction. The cover fastening part (485) may be coupled to the multiple fastening grooves (425a) and the multiple fastening holes (425b).

[0408] The second tray (400b) may include a third extension wall (1433) extending from the second tray wall (410) and forming a flow path for the supplied fluid.

[0409] The third extension wall (1433) may include a first wall part (1434) extending in the direction in which the plurality of cells are arranged, that is, in the direction in which the plurality of tray parts (401a, 401b, 401c) forming the plurality of cells are arranged.

[0410] The third extension wall (1433) may include a second wall part (1435) that extends from both ends of the first wall part (1434) to the second extension wall (431) and is connected to the second extension wall (431). The internal space defined by the first wall part (1434) and the second wall part (1435) may form a fluid flow path.

[0411] When defining the first width (W1') of the first to third tray parts (401a, 401b, 401c) based on the arrangement direction of the first to third tray parts (401a, 401b, 401c), the horizontal width of the third extension wall (1433), i.e., the second width (W2') of the first wall part (1434), may be equal to or smaller than the first width (W1'). The second width (W2') of the third extension wall (1433) may be larger than the diameter (D1) of the cell (360).

[0412] The third extension wall (1433) of the second tray (400b) can be in contact with the first tray (700). The first extension wall (713) of the first tray (700) includes a first portion extending in one direction (e.g., upward), and the first portion can be in contact with the first portion (1434a) of the first wall portion (1434).

[0413] The first part (1434a) may extend in one direction (e.g., upward) from the second contact end (412c). A first surface (e.g., a surface in the vertical direction) of the first part (1434a) may contact a second surface (e.g., a surface in the vertical direction) provided on the first extension wall (713) of the first tray (700). Therefore, in the area where the third extension wall (1433) is provided, the first tray (700) and the second tray (400b) may be in contact with each other through at least one of the first and second surfaces, thereby maintaining the connection. Therefore, stable contact and connection can be achieved between the first tray (700) and the second tray (400b).

[0414] The first wall part (1434) of the third extension wall (1433) may include a second part (1434b) that extends in one direction (e.g., upward) at a set angle from the first part (1434a). The second part (1434b) may extend in an inclined direction away from the first tray (700). The first wall part (1434) may include a third part (1434c) that extends in one direction (e.g., upward) from the second part (1434b).

[0415] In the area where the second extension wall (714) of the first tray (700) is provided, contact is made between the first contact end (719) and the second contact end (412c). The contact structure of the first tray (700) and the second tray (400b) can be equally applied to the second embodiment described above.

[0416] Based on the contact surfaces of the first and second contact ends (719, 412c), the second extension wall (714) of the first tray (700) can be extended obliquely. Based on a point of the first tray or the second tray, the end (714a) of the second extension wall (714) of the first tray (700) can be positioned higher than the end (431b) of the second extension wall (431) of the second tray (400b).

[0417] The second tray (400b) may include a first part (411) provided on one side (e.g., the lower side) of the second extension wall (420) and a second part (412) provided on the other side (e.g., the upper side). For example, the thickness (t2') of the first part (411) and the second part (412) may be the same or substantially the same.

[0418] The second part (412) may be provided with a reinforcing rib (436). The thickness (t1') of the second part (412) provided with the reinforcing rib (436) may be greater than the thickness (t2') of the first part (411).

[0419] The second tray (400b) may include a second extension wall (431) extending in one direction (e.g., upward) from the second part (412). For example, the thickness (t3') of the second extension wall (431) may be smaller than the thickness (t2') of the first part (411).

[0420] The second tray (400b) may include a third extension wall (1433) that forms a path for the fluid supplied to the cell (360). The thickness (t4') of the third extension wall (1433) may be formed to be equal to or greater than the thickness (t3') of the second extension wall (431) so as not to be easily deformed by the pressure of the fluid.

[0421] The second tray (400b) may include a coupling protrusion (422c) that protrudes in one direction (e.g., downward) from the first extension wall (420). The coupling protrusion (422c) may be inserted into a groove of the tray supporter (450b). The coupling protrusion (422c) may be positioned between a first edge (422a) that extends in one direction (e.g., downward) from one edge of the second tray (400b) and a second edge (422b) that extends in one direction (e.g., downward) from the other edge.

[0422] The second extension wall (714) of the first tray (700) may be extended in a round shape to have a radius of curvature (R1) set based on the center (C2) of the shaft (520). The second extension wall (431) of the second tray (400b) may have a radius of movement (R2) set based on a predetermined center of movement (C3).

[0423] The center (C2) of the shaft (520) and the center of movement (C3) may be formed at different positions. For example, the center of movement (C3) may be formed at a position lower than the center (C2) of the shaft (520). With this configuration, when the second tray (400b) returns from the ice-making position to the ice-making position, the phenomenon of the second tray (400b) being folded and inserted into the area of ​​the first cell (710b) due to interference with the first tray (700) can be prevented. In addition, the contact and sealing effect between the first tray (700) and the second tray (400b) can be improved.

[0424] FIG. 33 and FIG. 34 are cross-sectional views showing the operation of the ice guide when the ice-making operation is performed in the ice maker according to the third embodiment of the present invention.

[0425] Referring to FIGS. 33 and 34, when the driving unit (510) is driven in the forward direction by a set angle in a state where ice making is complete, the contact between the ice and the first tray (700) is separated, and the ice (I) can move to a state where it is located on the second tray (400b). Since the adhesive force (or contact area) between the ice and the second tray (400b) is greater than the adhesive force (or contact area) between the ice and the first tray (700), the ice and the first tray (700) can be easily separated during the ice-making process.

[0426] When the second tray (400b) moves in the forward direction, the moving guide (487) of the second tray cover (480b) can move in the forward direction together with the second tray (400b). The moving guide (487) can move along the outer surface of the second extension wall (714) of the first tray (700). At this time, the end of the moving guide (487) can move in a state adjacent to the second extension wall (714) with or without contacting the second extension wall (714).

[0427] The end of the above-mentioned moving guide (487) can move to the first contact end (719) of the first tray (700) or to a position adjacent to the first contact end (719). In this process, ice debris (Id) that may be present in the first and second contact ends (719, 412c) can be separated from the tray assembly.

[0433] 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 (800) passes through it. The opening (352) may be formed to have a predetermined curvature corresponding to the shape of the outer circumferential surface of the cell (360). The opening (352) may be configured to have an area larger than the cross-sectional area of ​​a plurality of first cells of the first tray (800) so that the plurality of first cells may pass through it.

[0434] 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 (815a) of the first tray (800).

[0435] The bracket (220) may include a fastening boss (220d) fastened to the first tray (800). The fastening boss (220d) may be provided on a joining wall (221a, see FIG. 4). In a state where the tray joining portion (354) is fastened to the fastening portion (815a), the first tray (800) and the first tray supporter (350) may be placed on one side (e.g., the lower side) of the bracket (220) and fastened to the fastening boss (220d) of the bracket (220) by a fastening member.

[0442] The second part (412) may include a plurality of parts having different degrees of internal deformation. The plurality of parts may include a first part (412a) having a first degree of internal deformation and a second part (412b) having a second degree of internal deformation. For example, the thickness of the first part (412a) may be greater than the thickness of the second part (412b).

[0443] The thickness (t1) of the first part (411) may be greater than the thickness of the second part (412b). The thickness of the first part (411) may be equal to or substantially equal to the thickness of the first part (412a).

[0451] The above ice maker (200d) may include a first tray supporter (350). The description of the first tray supporter (350) refers to the description of the fourth embodiment.

[0452] FIG. 40 is a perspective view showing the configuration of a second tray according to a fifth embodiment of the present invention, and FIG. 41 is a cross-sectional view showing the configuration of an ice maker according to a fifth embodiment of the present invention.

[0453] Referring to FIGS. 40 and 41, the first tray (900) according to the fifth embodiment of the present invention can define a first cell that is a part of the cell (360). Considering an ice maker (200d) equipped with a plurality of cells (360), the first tray (900) can include a plurality of first cells.

[0454] The first tray (900) may include a first cell wall (911) defining a first cell surface. The inner surface of the first cell wall (911) forms the first cell surface, and the first cell surface (910a) may be understood to define the outer surface of the first cell.

[0455] The first tray (900) may include an extension wall (915) extending from one side (e.g., the upper side) of the plurality of first cells (910b). A fastening portion coupled to the first tray supporter (350) may be formed on the extension wall (915).

[0456] The first tray (900) may include a connecting wall extending recessed from the extension wall (915) and connected to the first cell wall (911). The connecting wall may be connected to the periphery of the first cell wall (911). The second connecting wall may include a first wall (917a) extending in one direction (e.g., left-right direction) from a portion (e.g., rear portion) of the first cell wall (911).

[0457] 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 be arranged to surround at least a portion of the through hole (911a), thereby guiding the fluid discharged through the through hole (911a) to the outside of the first cell wall (811).

[0458] 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 connecting wall of the first tray (900) and the second extension wall (431) of the second tray (400d) can be spaced apart from each other.

[0459] The above channel is positioned higher than the portion where the first tray (900) and the second tray (400d) come into contact to form the cell (360). Fluid or ice remaining in the channel can be removed by interference from the ice guide (487) during the ice-making process.

[0460] The bracket (220d) includes a joining wall to which the first tray (900) is joined. The bracket (220d) may include a supporting wall (229) for supporting the first tray (900). The supporting wall (229) may extend in one direction (e.g., downward) from the joining wall.

[0461] 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.

[0462] 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).

[0463] 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).

[0464] The above support wall (229) may include a second support wall (229b) that supports the connecting wall of the first tray (900). The second support wall (229b) may have a bent shape corresponding to the shape of the connecting wall.

[0465] The second support wall (229b) may be in contact with the connecting wall. The second support wall (229b) may extend along the connecting wall. The second support wall (229b) may be arranged to surround at least a portion of the connecting wall.

[0466] In the first cell on the central side, water can be supplied through a water supply unit (240). Water is supplied first to the first cell 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 (435).

[0467] The discharge portion (243) of the above-described water supply portion (240) may overlap the first cell wall (911) defining the first cell on the central side. Accordingly, the fluid discharged from the above-described water supply portion (240) may fall onto the first cell wall (911) and flow downward along the first cell wall (911). Accordingly, the first cell wall (911) on the central side may be understood to perform the function of the guide surface (311) described in the first embodiment.

[0468] The second tray (400d) may include a first extension wall (420), a second extension wall (431), and a third extension wall (1433). The third extension wall (1433) may include a first wall part (1434) and a second wall part (1435). The description of these refers to the description of the previous embodiment.

[0469] The end portion (e.g., the upper portion (431b)) of the second extension wall (431) may be formed to be higher than the first through hole (911a) by a set height (△). Accordingly, it is possible to prevent the fluid from leaking out of the second tray (400d).

[0470] The second extension wall (431) of the second tray (400d) may extend obliquely in one direction (for example, upward) from the second contact end (412c). The second extension wall (431) is spaced apart from the first wall (917a), and the distance (△) between the second contact end (412c) and the end (431b) may be formed at a constant distance. Accordingly, it is possible to prevent ice from accumulating between the second extension wall (431) and the first wall (917a).

[0471] Figure 42 is a plan view showing the configuration of a second tray according to the sixth embodiment of the present invention.

[0472] Referring to FIG. 42, the second tray (400e) according to the sixth embodiment of the present invention may include a guide member (405a, 405b) for guiding water spreading from the first tray part (401a) forming the central cell to the second and third tray parts (401b, 401c) forming the cells on both sides.

[0473] The above guide members (405a, 405b) may be provided on the inside of the third extension wall (1433). The guide members (405a, 405b) may be arranged in the water supply path (435). The guide members (405a, 405b) may be configured to extend from the second cell (410b) formed in the first tray part (401a) toward the second cell (401b) formed in the second and third tray parts (401b, 401c).

[0474] The above guide member (405a, 405b) may include a first guide (405a) extending from the first tray part (401a) toward the second tray part (401b). The width of the first guide (405a) in one direction (e.g., in the X-axis direction) may form “a”. The first guide (405a) may have a bent shape.

[0475] The first guide (405a) may include a first part extending obliquely in a direction away from the first tray part (401a) and a second part bent from the first part and extending obliquely in a direction toward the second tray part (401b).

[0476] The width of the first part or the second part in one direction (e.g., in the X-axis direction) may form "b". The b may be smaller than the a. The width of the first part may be equal to or substantially equal to the width of the second part.

[0477] The width of the flow path between the first guide (405a) and the first wall part (1434) can be reduced based on the direction of water spreading due to the inclined shape of the first part. Accordingly, water can be guided by the first part and spread at an increased speed from the first tray part (401a) to the second tray part (401b). The water spread by the first part can flow into the second tray part (401b) along the second part.

[0478] The above guide member (405a, 405b) may include a second guide (405b) extending from the first tray part (401a) toward the third tray part (401c). The description of the second guide (405b) refers to the description of the first guide (405a).

[0479] The present invention relates to an ice maker and / or a refrigerator equipped with an ice maker, and has remarkable industrial applicability because water supply to a tray can be easily accomplished through a wall that guides the flow of water supplied to the tray.
