Description

refrigerator

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

[0002] A refrigerator is a home appliance that stores food at low temperatures within an internal storage space enclosed by a door. The refrigerator uses cold air to cool the interior of the storage space, allowing the stored food to remain refrigerated or frozen. Typically, refrigerators are equipped with an ice maker to produce ice.

[0003] The ice maker above generates ice by cooling water supplied from a water source or water tank into a tray. Furthermore, the ice maker can remove the ice from the tray using a heating or twisting method. This 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.

[0005] An embodiment of the present invention aims to provide an ice maker and / or a refrigerator equipped with an ice maker capable of producing ice of a desired shape during ice making by providing a cell wall forming a part of a cell in a pusher for ice making.

[0100] Meanwhile, from the perspective of the material of the object, a large degree of internal deformation of the object may mean that the object has high rigidity. The thermal conductivity may be a unique material characteristic of the object. Even when the material of the object is the same, the degree of internal deformation may vary depending on the shape of the object, etc. The degree of internal deformation may be affected by an internal deformation reinforcement portion extended in the direction in which the external force is applied. The greater the rigidity of the internal deformation reinforcement portion, the greater the degree of internal deformation. The greater the height of the extended internal deformation reinforcement portion, the greater the degree of internal deformation.

[0101] In the present invention, the degree of restoration refers to the degree to which an object deformed by an external force is restored to its shape before the external force was applied after the external force is removed, and is defined as a value determined by the shape including the thickness of the object, the material of the object, etc.

[0102] Meanwhile, from the perspective of the material of an object, a high degree of resilience of the object may indicate a high modulus of elasticity. The modulus of elasticity may be a unique material characteristic of the object. Even when the material of an object is the same, the degree of resilience may vary depending on the shape of the object, etc.

[0125] 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).

[0126] 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.

[0127] 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).

[0128] 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 positioned closer to one end (e.g., a front end) than to the other end (e.g., a rear end).

[0129] The 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) instead of toward the tray assembly. For example, the blocking plate (227a) may extend in one direction (e.g., upward) from the first wall (221). The blocking plate (227a) may be spaced laterally from the suction hole (224a), and a plurality of cells (360) may be arranged between the suction hole (224a) and the blocking plate (227a).

[0130] The above blocking plate (227a) is positioned further from the suction hole (224a) than the cell (360) furthest from the suction hole (224a), thereby preventing the phenomenon of cold air bypassing multiple cells (360) and being discharged from the bracket (220).

[0131] The bracket (220) may include a fourth wall (224) to which a pusher (540) is coupled. The fourth wall (224) may extend in one direction (e.g., downward) from one end (e.g., rear end) of the first wall (221) and may form a wall of one side (e.g., rear) of the bracket (220).

[0132] The above ice maker (200) may include a first tray assembly and a second tray assembly.

[0133] 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).

[0134] The second tray assembly may include a second tray (400), a second tray case, or the second tray (400) and a second tray case.

[0135] The second tray case may include at least one of a second tray supporter and a second tray cover.

[0136] The above bracket (220) can define at least a portion of a space that accommodates the first tray assembly and the second tray assembly.

[0137] The bracket (220) may be arranged, for example, on 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) through which water is supplied may be arranged on one side (e.g., the upper side) of the water supply unit (240).

[0138] Since the above water supply unit (240) is positioned lower than the above water supply pipe, water is guided in one direction (e.g., downward) without splashing up to the above water supply unit (240), and even if water is moved in one direction (e.g., downward) due to the lowered height, the amount of splashing can be reduced.

[0139] 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).

[0140] The above ice maker (200) may include a cell (see 360 ​​in FIG. 6), which is a space where water changes into ice due to cold.

[0141] 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 (321a, see FIG. 7) formed by the first tray (300) and a second cell (411a, see FIG. 7) formed by the second tray (400).

[0142] The above first tray (300) can be coupled to the bracket (220).

[0143] The above bracket (220) may include a joining wall (229) that protrudes in one direction (e.g., downward) from the first wall (221) and is joined to the first tray (300). The joining wall (229) may be joined to the periphery of the first tray (300).

[0144] The second tray (400) can be positioned so as to be able to move relative to the first tray (300). The second tray (400) can move linearly or rotate.

[0145] 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.

[0146] On the other hand, after the ice making is completed, the second tray (400) may move with respect to the first tray (300) during the ice removal process, so that the second tray (400) may be separated from the first tray (300).

[0147] In this embodiment, the first tray (300) and the second tray (400) can be arranged in one direction (e.g., up and down) while forming the cell (360). Accordingly, the first tray (300) can be referred to as an upper tray, and the second tray (400) can be referred to as a lower tray.

[0148] 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).

[0149] 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.

[0150] The first tray (300) may include a plurality of tray parts. The number of the plurality of tray parts may correspond to the number of the plurality of cells (360).

[0151] The first tray (300) can define a first cell that is part of a cell (360). Each of the plurality of tray parts can define the first cell.

[0152] The first tray (300) may include a first tray wall (321) forming a part of the cell (360).

[0153] The first tray (300) may include a first extension wall (327) extending in a first direction (e.g., horizontally) from the first tray wall (321). For example, the first extension wall (327) may extend in the first direction (e.g., horizontally) around the upper end of the first tray wall (321).

[0154] The above ice maker (200) may include a first pusher (700). The first pusher (700) may be provided to be movable by receiving power from the driving unit (510). The first pusher (700) may be referred to as a "movable pusher."

[0155] The ice maker (200) may include a guide bar (350) that forms a slot (355) that guides the movement of the first pusher (700). For example, the guide bar (350) may be configured to extend in one direction (e.g., upward) from both sides of the first extension wall (327) of the first tray (300).

[0156] However, unlike this, the guide bar (350) may be provided as a separate part separated from the first tray (300).

[0157] A protrusion (740) of the first pusher (600) can be inserted into the above slot (355). The protrusion (740) can be guided along the guide slot (355).

[0158] The first pusher (700) may include at least one bar (720). For example, the first pusher (700) may include a number of bars (720) equal to the number of cells (360), but is not limited thereto.

[0159] When the ice maker includes a plurality of cells (360), the first pusher (700) may include a plurality of bars (720). Two adjacent bars (720) may be connected by a connecting member (710).

[0160] For example, the connecting member (710) may extend in the direction in which the plurality of bars (720) are arranged so as to connect the ends of one side (e.g., the upper side) of the bars (720) to each other. For example, the connecting member (710) may include a connecting bar. Accordingly, interference between the connecting member (710) and the first tray (300) can be prevented during the process in which the bar (720) is inserted into the cell (360).

[0161] The above bar (720) can push out ice located in the cell (360) during the ice-breaking process. For example, the bar (720) can be inserted into the cell (360) by penetrating the opening (324, through hole) of the first tray (300).

[0162] The first pusher (700) may include a wall part (730) for forming at least a portion of the cell (360).

[0163] The above wall part (730) may be provided at the end of the above bar (720).

[0164] The above wall part (730) may be configured to have a curvature corresponding to the curvature of the cell surface so as to form a portion of the cell surface of the cell (360).

[0165] The above wall part (730) may have a diameter larger than the diameter of the above bar (720).

[0166] The first pusher (700) may be coupled to the link (490). At this time, the first pusher (700) may be coupled to the link (490) so as to be movable. Accordingly, when the link (490) moves, the first pusher (700) may also move along the slot (355).

[0167] The second tray case may include, for example, a second tray cover (480) and a second tray supporter (450). The second tray cover (480) and the second tray supporter (450) may be formed integrally, or may be manufactured as separate components and then combined.

[0168] In this embodiment, the second tray cover (480) and the second tray supporter (450) may be manufactured as separate components and then combined. For example, the second tray (400), the second tray supporter (450), and the second tray cover (480) may be combined by a fastening member.

[0169] 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).

[0170] The second tray cover (480) may include a cover wall (481) forming an opening (482).

[0171] The above opening (482) can 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.

[0172] The above opening (482) may be configured to have an area larger than the cross-sectional area of ​​the plurality of second cells of the second tray (400) so that the plurality of second cells can pass through it.

[0173] The above cover wall (481) can be placed on one side (e.g., the upper side) of the first extension wall (420) of the second tray (400).

[0174] The second tray cover (480) may include a cover extension wall (483) that protrudes from the cover wall (481) and surrounds the peripheral wall (430) of the second tray (400).

[0175] A joining groove (484) may be formed in the above cover extension wall (483).

[0176] The projection (434) of the second tray (400) can be inserted into the above-mentioned joining groove (484). The projection (434) can be provided to protrude from the peripheral wall (430). The projections (434) can be provided in multiple numbers at positions corresponding to multiple cells (360). By the configuration in which the projections (434) are inserted into the above-mentioned joining groove (484), the second tray (400) can be prevented from shaking in the first direction (e.g., horizontal direction) and can be stably supported by the second tray cover (480).

[0177] The second tray cover (480) may include a cover fastening portion (485) that protrudes in one direction (e.g., downward) from the cover wall (481). A plurality of the cover fastening portions (485) are provided along the perimeter of one side (e.g., the bottom side) of the cover wall (481), and may be coupled to at least one of the fastening portion (425) of the second tray (400) and the supporter fastening portion (456) of the second tray supporter (450). At least a portion of the second tray supporter (450) may be positioned on one side (e.g., the bottom side) of the second tray (400).

[0178] The second tray supporter (450) can support the second tray (400) on one side (e.g., the lower side) of the second tray (400). For example, at least a portion of the second tray wall (410) forming the second cell (411a) of the second tray (400) can be supported by the second tray supporter (450).

[0179] The second tray wall (410) may include a second cell surface (410a) defining the second cell (411a).

[0180] The second tray supporter (450) may include a first wall (451) forming an outer surface. The first wall (451) may include a first side wall (e.g., a front wall), a second side wall (e.g., a side wall), and a third side wall (e.g., a rear wall) of the second tray supporter (450).

[0181] The second tray supporter (450) may include a second wall (453) forming one surface (e.g., an upper surface) of the second tray supporter (450).

[0182] The first extension wall (420) of the second tray (400) can be mounted on the second wall (453).

[0183] A first joining portion (459a) to which the first edge (422a, see FIG. 7) of the second tray (400) is joined can be formed on the second wall (453).

[0184] An insertion portion (458a) may be formed in the second wall (453) to which the second edge (422b, see FIG. 7) of the second tray (400) is coupled. The insertion portion (458a) may include a groove recessed from the second wall (453) to allow the second edge (422b) to be inserted.

[0185] The second tray supporter (450) may include a tray support wall (452) that is recessed in one direction (e.g., downward) from the second wall (453) to support at least a portion of the second tray wall (410) of the second tray (400). The tray support wall (452) may be referred to as a “third wall.”

[0186] The above tray support wall (452) can be surrounded by the first wall (451).

[0187] The second tray supporter (450) may include two extensions (455) provided on both sides of one end (e.g., the rear end) of the first wall (451). The two extensions (455) may protrude in one direction (e.g., rearward) from one end (e.g., the rear end) of the first wall (451).

[0188] Each of the above extension parts (455) may have a through hole (455a) formed into which a shaft connection part (463) of the arm (460) is inserted.

[0189] The above arm (460) can be provided at both ends of the shaft (520).

[0190] Among the two arms (460), the first arm may include a driving connection part (462) connected to the driving part (510). The first arm may constitute a driving arm.

[0191] Among the two arms (460) above, the second arm can form a secondary arm.

[0192] The above two arms (460) may each include a shaft connection portion (463) coupled with the shaft (520).

[0193] In the case of the first arm, the driving connection part (462) and the shaft connection part (463) can be placed on opposite sides.

[0194] One end of the arm (460) is connected to one end of a spring (470), so that when the spring (470) is tensioned, the position of the arm (460) can be moved to the initial position by the restoring force.

[0195] The second tray supporter (450) may include a link connecting portion (457a) to which a link (490) is connected. The link connecting portion (457a) is provided on both side walls of the second tray cover (450) so that two links (490) can be connected to each other.

[0196] In the process of moving the second tray (400), the link (490) can be movably connected to the second tray supporter (450) through the link connecting portion (457a).

[0197] The second tray supporter (450) may include a spring coupling portion (457b) to which the spring (470) is coupled. The spring coupling portion (457b) may include a ring to which one end (e.g., the lower end) of the spring (470) is caught.

[0198] The ice maker (200) may include a second pusher (540). The second pusher (540) may be coupled to the bracket (220), for example. The second pusher (540) may be referred to as a “fixed pusher.”

[0199] The above second pusher (540) may be provided in the same number as the number of cells (360), but is not limited thereto.

[0200] The second pusher (540) can push out ice located in the cell (360). For example, the second pusher (540) can come into contact with the second tray (400) forming the cell (360) by penetrating the second tray supporter (450), and pressurize the second tray (400) that has come into contact with it.

[0201] The second pusher (540) may include a coupling plate (542) coupled to the bracket (220) and at least one pushing bar (544) provided on the coupling plate (542). A plurality of pushing bars (544) may be connected to the coupling plate (542) while being spaced apart from each other in a first direction (e.g., horizontal direction).

[0202] The above ice maker (200) may include a heater (530, 535).

[0203] The above heater (530, 535) is placed in the sunken receiving space (453a) of the second tray supporter (450) and may include a first heater (530) for applying heat to the second tray (400).

[0204] The first heater (530) may be positioned adjacent to or in contact with one side (e.g., the lower side) of the second tray (400) to supply heat to a portion (e.g., the lower side) of the second tray (400).

[0205] The above first heater (530) may function as an ice-making heater that supplies heat to the second tray (400) during the ice-making process, or may operate to help create transparent ice during the ice-making process.

[0206] The above first heater (530) may be, for example, a wire type heater.

[0207] The above heater (530, 535) may include a second heater (535) 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.

[0208] The second heater (535) may be placed adjacent to the first tray (300). The second heater (535) may be, for example, a wire-type heater.

[0209] For example, the second heater (535) may be positioned so as to be in contact with the first tray (300) or may be positioned at a predetermined distance from the first tray (300). In either case, the second heater (535) may supply heat to the first tray (300), and the heat supplied to the first tray (300) may be transferred to the cell (360).

[0210] The above ice maker (200) may include a driving unit (510) that provides driving force. By receiving the driving force of the driving unit (510), the second tray (400) can move relative to the first tray (300).

[0211] The ice maker (200) may include a shaft (520) that passes through the through hole (455a) of the second tray supporter (450). The shaft (520) extends between the two extension parts (455) and may rotate by receiving power from the driving part (510).

[0212] The above driving unit (510) may include a motor and a plurality of gears.

[0213] The above driving unit (510) may include a cam that rotates or moves by receiving power from the motor. The ice maker (200) may include a sensor that detects the rotation or movement of the cam.

[0214] For example, the cam may be equipped with a magnet, and the sensor may be a Hall sensor for detecting the magnetism of the magnet during the rotation or movement of the cam. Depending on whether the sensor detects the magnet, the sensor may output different outputs, a first signal and a second signal. Either the first signal or the second signal may be a high signal, and the other may be a low signal.

[0215] 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 position of the second tray (400) can be indirectly determined based on the detection signal of the magnet provided in the cam.

[0216] For example, the water supply position, ice-making position, and ice-moving position can be distinguished and determined based on the signal output from the sensor.

[0217] The second tray (400) may be formed of a non-metallic material. For example, the second tray (400) may be formed of a flexible or malleable material that can be deformed when pressed by the second pusher (540). Although not limited, the second tray (400) may be formed of a silicone material, for example.

[0218] Accordingly, in the process of pressurizing the second tray (400) by the second pusher (540), the second tray (400) is deformed and the pressing force of the second pusher (540) can be transmitted to the ice. The ice and the second tray (400) can be separated by the pressing force of the second pusher (540).

[0219] 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).

[0220] 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 second pusher (540), when the pressing force of the second pusher (540) is removed, the second tray (400) can be easily restored to its original shape.

[0221] 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.

[0222] 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.

[0223] 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).

[0224] In the present embodiment, since the second tray (400) is deformed by being pressed by the second pusher (540), 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.

[0225] FIG. 5 is a drawing showing a part of a configuration of an ice maker according to an embodiment of the present invention, FIG. 6 is a cross-sectional view taken along line 6-6 of FIG. 2, and FIG. 7 is a cross-sectional view taken along line 7-7 of FIG. 2.

[0226] Referring to FIGS. 5 to 7, the first tray (300) according to an embodiment of the present invention can be coupled to a bracket (220).

[0227] The above first tray (300) may include at least one of a joining projection (329a) and a boss (329b) that are joined to the bracket (220).

[0228] The above-mentioned coupling protrusion (329a) or the boss (329b) may be provided on the first extension wall (327) and configured to protrude in one direction (e.g., upward).

[0229] The first tray (300) may include a plurality of tray parts. The number of the plurality of tray parts may correspond to the number of the plurality of cells (360).

[0230] The above multiple tray parts can be arranged in a row in one direction (e.g., in the X-axis direction).

[0231] The above first tray (300) can form an upper tray.

[0232] The first tray (300) may include a first portion (322) defining a portion of the cell (360). The first portion (322) may be, for example, a portion of the first tray wall (321).

[0233] The above first part (322) may include a first cell surface (322b) forming a first cell (321a).

[0234] The first portion (322) may include an opening (324). The opening (324) may be in communication with the first cell (321a).

[0235] The above first part (322) may include a part to which the first heater (530) is coupled.

[0236] The lowermost part of the first portion (322) can form a contact surface that comes into contact with the second tray (400).

[0237] The first tray (300) may include a second portion (323) that extends from a certain point of the first portion (322). The certain point of the first portion (322) may be one end of the first portion (322). Alternatively, the certain point of the first portion (322) may be a point of a contact surface that comes into contact with the second tray (400).

[0238] A part of the second portion (323) may be formed by the first tray wall (321), and another part may be formed by the first extension wall (327).

[0239] The first tray (300) may include an auxiliary storage room (325) that is connected to the cell (360). For example, the auxiliary storage room (325) may store water overflowing from the cell (360).

[0240] The above auxiliary storage room (325) may be formed by a storage room wall (325a). The storage room wall (325a) may extend in one direction (e.g., upward) around the opening (324).

[0241] The above first pusher (700) can pass through the opening (324) after passing the storage room wall (325a).

[0242] When the first tray (300) defines a plurality of first cells (321a), at least one (325b) of the plurality of storage chamber walls (325a) can support the water supply unit (240).

[0243] The first pusher (700) may extend between two guide bars (350). Both sides of the first pusher (700) may pass through the slots (355) of the guide bars (350) and be positioned on the outside of the guide bars (350).

[0244] Links (490) can be connected to each of the two sides of the first pusher (700).

[0245] The above link (490) may include a link body (491). The link body (491) may have a bent or rounded shape. Based on the shape of the link body (491), the link (490) can move during the movement process of the second tray assembly, while the link (500) can move the first pusher (700).

[0246] The above link (490) may include a first connecting portion (493) provided at one end of the link body (491) and a second connecting portion (495) provided at the other end of the link body (491).

[0247] The above first connecting portion (493) can be coupled to the second tray supporter (450). The above first connecting portion (493) can include a first coupling hole for coupling a link connecting portion (457a) provided on the second tray supporter (450).

[0248] The first connecting portion (493) can be connected to the second tray supporter (450) at a location spaced apart from the center of the shaft (520) or the center of the second tray assembly.

[0249] The second connecting portion (495) may include a second connecting hole for connecting the first pusher (700). The first pusher (700) may be connected to the second connecting portion (495) after passing through the slot (355).

[0250] As the second tray assembly moves, the link (490) connected to the second tray assembly moves along with it. When the link (490) moves, the first pusher (700) connected to the link (490) moves along the slot (355). The link (490) may play a role in converting the moving force of the second tray assembly into the moving force of the first pusher (700).

[0251] Arms (460) can be connected to both sides of the second tray supporter (450).

[0252] The above-mentioned arm (460) may include a arm body (461). The arm body (461) may have a bent or rounded shape.

[0253] The arm (460) may include a shaft connection portion (463) that protrudes from the arm body (461) in a direction toward the shaft (520) and is coupled to the shaft (520). The shaft connection portion (463) may pass through the through hole (455a) of the extension portion (455).

[0254] The above shaft connection part (463) can be provided at one end of the arm (460).

[0255] Among the two arms (460), the first arm (460) connected to the driving unit (510) may include a driving connection unit (462). The driving connection unit (462) may be axially coupled to the driving unit (510).

[0256] A spring (470) may be connected to the other end of the arm (460). The spring (470) may provide elasticity to the second tray supporter (450) so that the second tray (400) can maintain contact with the first tray (300).

[0257] The other end of the arm (460) may include a spring connecting portion (465) to which the spring (470) is coupled. The spring connecting portion (465) may include a coupling hole to allow the end of the spring (470) to be coupled.

[0258] The first tray (300) may include a first cell surface (322b) defining a first cell (321a). The second tray (400) may include a second cell surface (410a) defining a second cell (411a).

[0259] When the first tray (300) and the second tray (400) are in a closed position, i.e., an ice-making position, the first cell (321a) and the second cell (411a) can be combined to form a cell (360).

[0260] The second tray (400) may include a second tray wall (410) forming the second cell (411a) and a peripheral wall (430) extending upward from the second tray wall (410) and surrounding the second portion (323) of the first tray (300).

[0261] In the process of the second tray (400) moving from the water supply position to the ice-making position, the water supplied to the cell (360) can be reduced from leaking between the first tray assembly and the second tray assembly. In addition, the water that expands during the ice-making process can be reduced from leaking between the first tray assembly and the second tray assembly and freezing.

[0262] A recessed portion (412) may be formed at the lower end of the second tray wall (410). By virtue of the recessed portion (412), even if the second tray wall (410) is deformed during the ice-making expansion process, a desired ice shape can be realized.

[0263] Figures 6 and 7 show the first pusher (700) raised to the furthest distance (e.g., the highest height) relative to a point of the first tray or the second tray. When the first pusher (700) is raised to the highest height, the wall part (730) of the first pusher (700) may be at a position higher than one end (e.g., the upper end) of the storage chamber wall (325a).

[0264] FIG. 8 is a front view showing a part of the configuration of an ice maker according to an embodiment of the present invention, FIG. 9 is a cross-sectional view of the ice maker taken along line 9-9 of FIG. 8, and FIG. 10 is a cross-sectional view showing the configuration of the ice maker at a water supply position.

[0265] Referring to FIGS. 8 to 10, the first tray assembly and the second tray assembly according to an embodiment of the present invention can be arranged in contact with each other to form a cell (360).

[0266] The above first tray (300) can be placed on one side (e.g., the upper side) of the above second tray (400).

[0267] The second tray supporter (450) can support at least one side (e.g., the lower side) of a portion of the second tray (400). The second tray cover (480) can cover the other side (e.g., the upper side) of at least a portion of the second tray (400).

[0268] The above cell (360) may include a guide bar (350) extending in one direction (e.g., upward). The guide bar (350) may be positioned higher than the first extension wall (327) of the first tray (300).

[0269] The peripheral wall (430) of the second tray (400) can be arranged to surround the first portion (322), which is a part of the first tray wall (321).

[0270] The first tray (300) may include a plurality of tray parts (300a, 300b, 300c) arranged in a first direction (e.g., X-axis direction) to define a plurality of cells (360).

[0271] The above multiple tray parts (300a, 300b, 300c) may include a first tray part (300a) in the center and second and third tray parts (300b, 300c) on both sides.

[0272] Water is supplied to the first tray part (300a), and water is first filled into the first tray part (300a) and then can be filled into the second and third tray parts (300b, 300c) through a water spreading phenomenon.

[0273] The peripheral wall (430) of the second tray (400) may be surrounded by a cover extension wall (483) of the second tray cover (480).

[0274] The above second tray (400) can be supported on the second tray cover (480) through the protrusion (434).

[0275] Figure 9 shows a wall part (730) of the first pusher (700) shielding the opening (324) of the first tray (300). At this time, the first and second tray assemblies may be in the ice-making position.

[0276] Fig. 10 shows the first and second tray assemblies when they are in the water supply position. In the water supply position, the second tray assembly can be moved in the forward direction by a predetermined angle by the driving unit (510).

[0277] In the above water supply position, the first contact surface (323) formed on one end (e.g., the lower end) of the first tray (300) is located at a position spaced apart from the second contact surface (415) formed on one end (e.g., the upper end) of the second tray wall (410).

[0278] When the second tray assembly moves backward from the water supply position to the ice-making position, the first contact surface (323) can come into contact with the second contact surface (415).

[0279] The above water supply unit (240) can be placed on one side (e.g., the upper side) of the opening (324) of one of the plurality of tray parts (300a, 300b, 300c).

[0280] When water is supplied through the above water supply unit (240), water can be supplied to the internal space of the first and second trays (300, 400) through the opening (324) of the first tray (300).

[0281] The first pusher (700) may be in a state of moving in one direction (e.g., downward) to open the opening (324). At this time, the height of the first pusher (700) with respect to a point of the first tray or the second tray may be at a position lower than the maximum height of FIG. 6.

[0282] The wall part (730) of the first pusher (700) is located inside the first tray (300), and the bar (720) of the first pusher (700) is located at a position passing through the opening (324).

[0283] Water supplied from the above water supply unit (240) can be supplied into the interior of the first and second trays (300, 400) through the space between the bar (720) and the opening (324).

[0284] FIG. 11 is a top perspective view showing the configuration of a first pusher according to an embodiment of the present invention, FIG. 12 is a bottom perspective view showing the configuration of a first pusher according to an embodiment of the present invention, FIG. 13 is a perspective view showing the configuration of a link according to an embodiment of the present invention, and FIG. 14 is a side view showing the configuration of a link according to an embodiment of the present invention.

[0285] Referring to FIGS. 11 to 14, a first pusher (700) according to an embodiment of the present invention may include a connecting member (710) extending in a first direction (e.g., X-axis direction) corresponding to the direction in which a plurality of cells (360) are arranged.

[0286] The first pusher (700) may include a bar (720) extending from the connecting member (710) toward the cell (360). A plurality of bars (720) may be provided corresponding to a plurality of cells (360).

[0287] The bar (720) may extend in one direction (e.g., up and down) and may be formed in a straight shape or a curved shape with at least a portion of it being rounded. The diameter of the bar (720) may be formed to be smaller than the diameter of the opening (324) of the first tray (300). The bar (720) may be inserted into the cell (360) by penetrating the opening (324). The first pusher (720) may be referred to as a penetrating pusher that penetrates the cell (360).

[0288] The above connecting member (710) can connect the ends of one side (e.g., the upper side) of the plurality of bars (720) to each other.

[0289] The first pusher (700) may include a protrusion (740) that protrudes laterally from the connecting member (710). A plurality of protrusions (740) may be provided on both sides of the connecting member (710).

[0290] The protrusion (740) may include a guide connecting portion (741) penetrating the slot (355). For example, the cross-section of the guide connecting portion (741) may be formed in a circular, oval, or polygonal shape. The guide connecting portion (741) may be positioned in the guide slot (355).

[0291] The above guide connecting portion (741) can be moved longitudinally along the guide slot (355) while positioned in the guide slot (302). For example, the guide connecting portion (265) can be moved in one direction (e.g., up and down).

[0292] The above protrusion (740) may include a link connecting portion (743) for coupling with the link (490). In order to enable relative movement while the link connecting portion (743) is coupled with the link (490), the link connecting portion (743) may be formed in a cylindrical shape.

[0293] The above link connecting portion (743) can be inserted into the second connecting portion (495) of the link (490). The above link connecting portion (743) can have a smaller height in one direction (e.g., up-down direction) than the above guide connecting portion (741).

[0294] The above protrusion (740) may include a catch (745) that supports the link (490). The catch (745) may extend outward from the link connection (743) and have a height greater than the height of the link connection (743) in one direction (e.g., in the vertical direction).

[0295] The above link connecting portion (743) penetrates the second connecting portion (495) of the link (490), and the catch portion (745) is located on the outside of the second connecting portion (495) to support the link (490). By the catch portion (745), the link (490) can be prevented from being separated from the first pusher (700).

[0296] The shape of the second connecting portion (495) corresponds to the shape of the catch portion (745), and the second connecting portion (495) may be formed to be slightly larger than the catch portion (495).

[0297] When assembling the link (490) to the first pusher (700), the link (490) is positioned and pushed so that the catch (745) passes through the second connection (495), so that the link connection (743) is inserted into the second connection (495). In addition, the link (490) can be moved so that the link (490) and the catch (745) interfere with each other.

[0298] The above link (490) may include a link body (491). The link body (491) may include a first body (491a) extending in a first direction and a second body (491b) extending in a second direction.

[0299] The above link body (491) may include a bending portion (491c) connecting the first body (491a) and the second body (491b). The bending portion (491c) may have a bent or rounded shape. By the bending portion (491c), the link body (491) may be configured to include a plurality of portions extending in different directions.

[0300] The above link (490) may include a first connecting portion (493) provided at one end of the link body (491). The first connecting portion (493) may be formed at an end of the first body (491a).

[0301] The above first connecting portion (493) can be movably connected to the link connecting portion (457a) of the second tray supporter (450).

[0302] The above link (490) may include a second connecting portion (495) provided at the other end of the link body (491). The second connecting portion (495) is formed at an end of the second body (491b) and may be movably coupled to the link connecting portion (743) of the first pusher (700).

[0303] When the second tray assembly moves, the link (490) moves together, and in this process, the first pusher (700) connected to the link (490) can move along the slot (355).

[0304] Fig. 15 is a cross-sectional view showing the ice maker in the water supply position, and Fig. 16 is a side view showing the ice maker in the water supply position.

[0305] Referring to FIGS. 15 and 16, when the second tray assembly is in the water supply position, the second tray assembly, i.e., the second tray (400), may be in a position where it has moved in the forward direction by a set angle (θ) by the driving unit (510). For example, the set angle may be a value within a range of 7 to 15°.

[0306] As the second tray (400) moves, the link (490) moves together with the second tray (400), and the first pusher (700) can move in one direction (for example, downward) by the second connecting portion (495) of the link (490).

[0307] The first pusher (700) can move in one direction (e.g., lower) to a position where the wall part (730) can open the opening (324) of the first tray (300). The bar (720) of the first pusher (700) can be at a position where it passes through the opening (324).

[0308] The above wall part (730) can be moved further in one direction (e.g., downward) from the opening (324) to be positioned inside the first cell (321a). Through the space between the bar (720) and the opening (324), water flows into the interior of the first cell (321a) and fills the interior of the second cell (411a) of the second tray (400).

[0309] Water supplied from the outside of the opening (324) can pass through the opening (324) and hit the wall part (730). The outer surface (e.g., the upper surface) of the wall part (730) can include a guide surface (735) that guides water into the interior of the first cell (321a).

[0310] Water hitting the above guide surface (735) can spread and flow (e.g., drop) in one direction (e.g., downward). By the above guide surface (735), the phenomenon of water splashing during the water supply process can be prevented.

[0311] Water can be supplied to any one of the multiple cells (360) through the above water supply unit (240). For example, water can be supplied to the central cell.

[0312] When the preset amount of water supply is completed, the water can be supplied by spreading from the central cell (360) to the cells on both sides (360) for a preset period of time. At this time, the water can flow along the peripheral wall (430) of the second tray (400).

[0313] Since the water supply is performed while the second tray (400) is moved in the forward direction by the set angle, water can be easily spread to a number of cells (360).

[0314] At the above-mentioned water supply position, the height of the first pusher (700), i.e., the height of the uppermost part of the first pusher (700), may be located at the first height (H1). The reference point for determining the height may be a point of the first tray (300), for example, the first extension wall (327).

[0315] At the above water supply position, the first compression force (F1) of the spring (470) can be applied between the arm (460) and the second tray (400).

[0316] Another embodiment of the water supply location is proposed.

[0317] In FIG. 15 and FIG. 16, it was described that when the first pusher (700) moves (e.g., descends), the wall part (730) moves toward the inside of the opening (324) of the first tray (300) to open the opening (324). Alternatively, when the first pusher (700) rises, the wall part (730) may be configured to move toward the outside (e.g., upper side) of the opening (324) of the first tray (300) to open the opening (324).

[0318] Figure 17 is a cross-sectional view showing the ice maker in the ice-making position, and Figure 18 is a side view showing the ice maker in the ice-making position.

[0319] Referring to FIGS. 17 and 18, when the second tray assembly is in the ice-making position, the second tray assembly, i.e., the second tray (400), may be moved in the reverse direction from the water supply position by the driving unit (510) to be in contact with the first tray (300).

[0320] The above driving unit (510) can reach the ice-making position by rotating in the reverse direction at an angle slightly greater than the set angle in order to seal the first tray (300) and the second tray (400).

[0321] A cell (360) can be defined by contact between the first tray (300) and the second tray (400).

[0322] As the second tray (400) moves in the reverse direction, the link (490) moves together with the second tray (400), and the first pusher (700) can move in one direction (for example, upward) by the second connecting portion (495) of the link (490).

[0323] The first pusher (700) can move (e.g., lower) to a position where the wall part (730) blocks the opening (324) of the first tray (300).

[0324] The above wall part (730) can define a third cell forming at least a portion of the above cell (360). The third cell can be defined by a third cell surface (732) forming one surface of the above wall part (730).

[0325] The third cell surface (732) may form at least a portion of the outer surface of the cell (360).

[0326] The third cell surface (732) may be formed on one surface (e.g., the bottom surface) of the wall part (730).

[0327] For example, the third cell surface (732) can be formed to be round with a predetermined curvature.

[0328] That is, the cell (360) can be defined by the first cell surface (322b) of the first tray (300), the second cell surface (410a) of the second tray (400), and the third cell surface (732) of the wall part (730).

[0329] The above first cell surface (322b), second cell surface (410a), and third cell surface (732) may each be called “first to third cell walls.”

[0330] At the above ice-making position, cold is supplied to the ice maker to perform an ice-making process, and ice (I) can be created in the cell (360). The ice (I) can be attached to the third cell surface (732) of the wall part (730).

[0331] At the above ice-making position, the height of the first pusher (700), that is, the height of the top of the first pusher (700), may be located at a second height (H2). The second height (H2) may be greater than the first height (H1).

[0332] Based on the height of the wall part (730) (height relative to the lower part of the ice maker), the second height of the wall part (730) at the ice-making position may be higher than the first height of the wall part (730) at the water supply position.

[0333] At the above ice-making position, a second compression force (F2) of the spring (470) may be applied between the arm (460) and the second tray (400). The second compression force (F2) may be formed to a size that allows sealing to be formed between the first tray (300) and the second tray (400). The second compression force (F2) may be greater than the first compression force (F1).

[0334] Fig. 19 is a cross-sectional view showing the ice maker in the first freezing position, and Fig. 20 is a side view showing the ice maker in the first freezing position.

[0335] Referring to FIGS. 19 and 20, when ice making is completed, the driving unit (510) can be driven further in the reverse direction. At this time, the second tray (400) is in contact with the first tray (300) and remains sealed, and the arm (460) can be moved to move the first pusher (700) in one direction (for example, upward) by the shaft (520). For example, the arm (460) can be moved further in the clockwise direction with reference to FIG. 20.

[0336] As the above arm (460) moves, the first pusher (700) moves upward, allowing the wall part (730) to separate from the ice (I). The phenomenon of the wall part (730) separating from the ice (I) can be understood as "first-stage separating."

[0337] Since the area where the wall part (730) and the ice are attached is relatively small, separation of the wall part (730) and the ice can be easily achieved by moving the first pusher (700) in one direction (for example, upward).

[0338] When the first difference is made, the second heater (535) can be driven.

[0339] At the above first difference position, the height of the first pusher (700), that is, the height of the uppermost part of the first pusher (700), may be located at a third height (H3). The third height (H3) may be greater than the second height (H2).

[0340] Based on the height of the above wall part (730), the third height of the wall part (730) at the first freezing position may be higher than the second height of the wall part (730) at the freezing position.

[0341] At the first differential position, a third compression force (F3) of the spring (470) may be applied between the arm (460) and the second tray (400). The third compression force (F3) may be greater than the second compression force (F2).

[0342] Fig. 21 is a cross-sectional view showing the ice maker in the second freezing position, and Fig. 22 is a side view showing the ice maker in the second freezing position.

[0343] Referring to FIGS. 21 and 22, when the first ice-making operation is completed, the driving unit (510) can be driven in a forward direction to perform a second ice-making operation. When the angle of the second tray (400) at the ice-making position is 0°, the second tray (400) can move in a forward direction within a range of about 110 to 120° at the second ice-making position.

[0344] During the movement process of the second tray (400), ice (I) may be separated from the first cell surface (322b) of the first tray (300) or from the second cell surface (410a) of the second tray (400).

[0345] Regardless of which tray the ice (I) is located on, the ice (I) can be removed from the tray by the first pusher (700) or the second pusher (540).

[0346] As the second tray (400) moves forward, the link (490) moves together with the second tray (400), and the first pusher (700) can move in one direction (for example, downward) by the second connecting portion (495) of the link (490).

[0347] The first pusher (700) can be lowered to a position where the wall part (730) opens the opening (324) of the first tray (300) and is located inside the first cell (321a). For example, one end (e.g., the lower end) of the first pusher (700), i.e., the wall part (730), can be moved (e.g., lowered) to a position corresponding to one end (e.g., the lower end) of the first tray (300).

[0348] The bar (720) of the first pusher (700) may be located at a position passing through the opening (324).

[0349] Even if the ice (I) is attached to the first tray (300), the ice (I) can be pressed by the first pusher (700) as the first pusher (700) moves (e.g., descends).

[0350] That is, the wall part (730) can function as a “pushing part” that pressurizes the ice (I). When the wall part (730) pressurizes the ice (I), the ice (I) can be pressed by the third cell surface (732) of the wall part (730) or by the edge of the wall part (730).

[0351] When the second tray (400) is in the second-chasing position, the lower part of the second tray (400) can be deformed by contacting the pusher (540). If ice exists in the second tray (400), the ice can be separated from the second tray (400) by the pressure of the pusher (540).

[0352] The second freezing position of the second tray (400) may be called the “maximum freezing position.” In comparison, the first freezing position of the second tray (400) may be called the “freezing position.”

[0353] The second tray (400) may be formed of a flexible or ductile material that can be deformed when pressed by the second pusher (540).

[0354] In the above second difference, at least one heater among the first heater (530) and the second heater (535) can be driven.

[0355] At the above second difference position, the height of the first pusher (700), that is, the height of the uppermost part of the first pusher (700), may be located at a fourth height (H3). The fourth height (H4) may be smaller than the first height (H1).

[0356] Based on the height of the above wall part (730), the fourth height of the wall part (730) at the second shaving position may be lower than the first height of the wall part (730) at the water supply position.

[0357] At the above second difference position, the first compression force (F1) of the spring (470) can be applied between the arm (460) and the second tray (400).

[0358] Ice separated from the second tray (400) may fall and be stored in the ice bin (600). When the second ice-making operation is completed, the driving unit (510) may be driven to move the second tray assembly in the reverse direction and return to the ice-making position (Figs. 17 and 18).

[0359] When the water supply operation is initiated, the second tray assembly can move forward toward the water supply position (Figs. 15, 16). At the water supply position, fluid is supplied through the water supply unit (240) and the fluid can be supplied to a plurality of cells (360).

[0360] The present invention relates to an ice maker and / or a refrigerator equipped with an ice maker, and has remarkable industrial applicability because it is possible to implement ice of a desired shape during ice making by providing a cell wall forming a part of a cell in a pusher for ice removal.
