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.

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.

[0109] 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.

[0110] 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.

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.

[0132] The above bracket (220) can be coupled to at least one side of the storage room.

[0133] The bracket (220) may include a first wall (221). At least a portion of the first wall (221) may extend in one direction (e.g., in an up-down direction) and be coupled to one side of the storage compartment. The first wall (221) may form one side wall (e.g., a rear wall) of the bracket (220).

[0134] The bracket (220) may include a second wall (222) provided in front of the first wall (221). At least a portion of the second wall (222) may extend in one direction (e.g., in the vertical direction) and form the other side wall (e.g., the upper wall) of the bracket (220).

[0135] The above bracket (220) may include a third wall (223) provided on both sides of the first wall (221). The third wall (223) may form a side wall of the bracket (220).

[0136] The third wall (223) may extend in one direction (for example, forward) from both sides of the first wall (221) and be connected to the second wall (222). The internal space defined by the first to third walls (221, 222, 223) may form a space in which a tray assembly is placed.

[0137] A suction hole (223a) may be formed in one of the two third walls (223) to allow cold to flow toward the tray assembly. Cold sucked through the suction hole (223a) may flow toward the cell of the tray assembly.

[0138] On one side of the other of the two second walls (223), a driving device (500) including a lever (550) operated by a user to move the position of the tray assembly may be arranged.

[0139] The above driving device (500) may be a manual driving device.

[0140] The above driving device (500) may include a driving case (510) and a lever (550) connected to the driving case (510).

[0141] The above lever (550) may have a bent shape. For example, the lever (550) may be bent at least once at the grip portion (551) and may extend toward the drive case (510).

[0142] The above lever (550) may include a first part (551) that a user can hold. The first part (551) may be called a “handle.”

[0143] The above lever (550) may include a second part (552) that is bent from the first part (551) and extends in a direction parallel to the outer surface of the drive case (510). It may be understood that the first part (551) and the second part (552) are connected by the first bending portion.

[0144] The above lever (550) may include a connecting portion (553) coupled to the drive case (510). The connecting portion (553) may be bent from the second part (552) toward the drive case (510). It may be understood that the second part (552) and the connecting portion (553) are connected by the second bending portion.

[0145] The above connecting portion (553) can pass through the drive case (510) and be connected to a gear assembly (520, see FIG. 7) inside the drive case (510).

[0146] The above ice maker (200) may include a water supply guide (240). The water supply guide (240) may be coupled to the first wall (221), for example.

[0147] A water tank (C, see Fig. 8) can be detachably connected to the water supply guide (240). A user can connect the water tank (C) to the water supply guide (240) for water supply. The water tank (C) may be a dedicated water tank for water supply.

[0148] The above water supply guide (240) and water tank (C) are configured to supply fluid to the tray assembly and can be positioned at a position corresponding to any one of the multiple cells. Fluid supplied to any one of the cells can be distributed and introduced to other cells.

[0149] The above water supply guide (240) can be supported by the storage room wall (325a) of the first tray (300).

[0150] A second pusher (540) may be provided on the first wall (221). 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).

[0151] The above ice maker (200) may include a first pusher (700) that is movably provided by receiving power from a driving device (500). The first pusher (700) may operate to separate ice generated in the cell.

[0152] The above ice maker (200) may include a guide bar (350) that forms a slot (355) that guides the movement of the first pusher (700).

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

[0154] 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).

[0155] The second tray assembly may include a second tray (400), a second tray case, or the second tray (400) and a second tray case.

[0156] The second tray case may include at least one of a second tray supporter and a second tray cover.

[0157] The above bracket (220) can define at least a portion of a space that accommodates the first tray assembly and the second tray assembly.

[0158] The above ice maker (200) may include a cell (321a, 410a), which is a space where water changes into ice due to cold.

[0159] The first tray (300) may form at least a portion of the cell. The second tray (400) may form another portion of the cell. The cell may include a first cell (321a) formed by the first tray (300) and a second cell (411a) formed by the second tray (400).

[0160] The above first tray (300) can be coupled to the bracket (220).

[0161] The second tray (400) can be positioned so as to be able to move relative to the first tray (300). For example, the second tray (400) can move linearly or rotate.

[0162] For example, during the ice-making process, the second tray (400) may move relative to the first tray (300), so that the first tray (300) and the second tray (400) may come into contact. When the first tray (300) and the second tray (400) come into contact, the cell may be defined.

[0163] 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).

[0164] 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. 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.

[0165] A plurality of cells can be defined by the first tray (300) and the second tray (400). For example, the plurality of cells can include three cells.

[0166] When water is supplied to the above cell and the water is cooled by cold, ice of the same or similar shape as the above cell can be created. For example, the above cell can be formed into a sphere or a sphere-like shape. Of course, the above cell can also be formed into a rectangular parallelepiped shape or a polygonal shape.

[0167] 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.

[0168] The above first tray (300) can define a first cell (321a) which is a part of a cell. Each of the plurality of tray parts can define the first cell.

[0169] The first tray (300) may include a first tray wall (321) forming a part of the cell. The first tray wall (321) may include a first cell surface (322b) forming a first cell (321a).

[0170] 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 an end portion of one side (e.g., upper side) of the first tray wall (321).

[0171] 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 a driving device (500). The first pusher (700) may be referred to as a "movable pusher."

[0172] 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).

[0173] A protrusion (740) of the first pusher (700) can be inserted into the above slot (355). The protrusion (740) can be guided along the guide slot (355).

[0174] 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, but is not limited thereto.

[0175] When the ice maker includes a plurality of cells, the first pusher (700) may include a plurality of bars (720). Two adjacent bars (720) may be connected by a connecting member (710).

[0176] 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.

[0177] The above bar (720) can push out ice located in the cell during the ice-breaking process. For example, the bar (720) can be inserted into the cell by penetrating the opening (324, through hole) of the first tray (300).

[0178] The above bar (720) can pass through the opening (324) after passing the storage room wall (325a).

[0179] The above opening (324) can be communicated with the first cell (321a). Water can be supplied or cold can be supplied through the opening (324).

[0180] The first tray (300) may include a portion to which the first heater (530) is coupled. The first heater (530) may be placed on the first tray wall (321) at a position adjacent to the first cell (321a).

[0181] An end (e.g., the bottom end) of the first tray wall (321) can form a contact surface that comes into contact with the second tray (400).

[0182] The first tray (300) may include an auxiliary storage room (325) that is connected to the cell. For example, the auxiliary storage room (325) may store water overflowing from the cell.

[0183] 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).

[0184] The above first pusher (700) can pass through the opening (324) after passing the storage room wall (325a).

[0185] Both sides of the first pusher (700) may be coupled to a link (490). At this time, the first pusher (700) may be movably coupled to the link (490). For example, the link (490) may be coupled to the protrusion (740).

[0186] The above link (490) may have a bent or rounded shape. Based on the shape of the link (490), the link (490) can move during the movement of the second tray assembly, while the link (490) can move the first pusher (700) up and down.

[0187] The above link (490) may include one end coupled to the second tray supporter (450) and the other end coupled to the first pusher (700).

[0188] The above first pusher (700) can be connected to the other end of the link (490) after passing through the slot (355).

[0189] 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).

[0190] The above second tray case may include, for example, a second tray supporter (450).

[0191] The above second tray (400) and second tray supporter (450) can be joined by a fastening member.

[0192] 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).

[0193] 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).

[0194] FIG. 5 is a perspective view showing a part of the configuration of an ice maker according to a first embodiment of the present invention, FIG. 6 is a perspective view showing a configuration of a driving device according to a first embodiment of the present invention, and FIG. 7 is a schematic diagram showing a configuration of a driving device according to a first embodiment of the present invention.

[0195] Referring to FIG. 4 and FIGS. 5 to 7 together, the second tray supporter (450) according to the first embodiment of the present invention may include two extension parts (455). The two extension parts (455) may protrude in one direction (e.g., rearward) from one end (e.g., rear end) of the second tray supporter (450).

[0196] 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.

[0197] The above arm (460) can be provided at both ends of the shaft (580).

[0198] Among the two arms (460) above, the second arm can form a secondary arm.

[0199] The above arm (460) may include an arm body (461) having a bent or rounded shape.

[0200] The two arms (460) above may each include a shaft connection portion (463) that protrudes from the arm body (461) in a direction toward the shaft (580) and is coupled to the shaft (580). The shaft connection portion (463) may pass through the through hole (455a) of the extension part (455).

[0201] The above shaft connection part (463) can be provided at one end of the arm (460).

[0202] Among the two arms (460), the first arm (460) connected to the driving device (500) may include a driving connection part (462). The driving connection part (462) may be axially coupled to the driving device (500). The first arm may constitute a driving arm.

[0203] In the case of the first arm, the driving connection part (462) and the shaft connection part (463) can be placed on opposite sides with respect to the arm (460).

[0204] 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) at the ice-making position.

[0205] For example, the spring (470) may be a tension spring.

[0206] When the ice maker is in the ice-making position (see FIG. 10), the spring (470) can maintain a compressed state. In addition, the spring (470) can maintain a compressed state even when the ice maker moves forward toward the water supply position or the ice-removing position.

[0207] On the other hand, when the second tray (400) moves in the reverse direction at the above ice-making position, the adhesion between the first tray (300) and the second tray (400) can be improved while overcoming the elastic force of the spring (470).

[0208] However, if the user releases the lever (500) in the reverse movement state, there is a possibility that it will return to the ice-making position due to the restoring force of the spring (470), but by forming the elastic coefficient of the spring (470) not to be large, the reverse movement state can be maintained to some extent due to the resistance of the gear assembly (520) and the lever (550).

[0209] 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.

[0210] The second tray supporter (450) may include a link connecting part (457a) to which a link (490) is connected. The link connecting part (457a) is provided on the outer surface of both side walls of the second tray cover (450) so that two links (490) can be connected to each other.

[0211] 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 part (457a).

[0212] 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 allow the lower end of the spring (470) to be caught.

[0213] 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.”

[0214] The above second pusher (540) may be provided in the same number as the number of cells, but is not limited thereto.

[0215] The second pusher (540) can push out ice located in the cell. For example, the second pusher (540) can penetrate the second tray supporter (450) to come into contact with the second tray (400) forming the cell, and pressurize the second tray (400) that has come into contact with it.

[0216] The above ice maker (200) may include a heater (530, 535).

[0217] At least one of the above heaters (530, 535) can be placed in the sunken receiving space (453a) of the second tray supporter (450).

[0218] The second tray (400) may include a first heater (530, see FIG. 4) for applying heat thereto. 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 the lower portion of the second tray (400).

[0219] The above first heater (530) can function as an ice-making heater that supplies heat to the second tray (400) during the ice-making process, or can function as a transparent ice heater that helps create transparent ice during the ice-making process.

[0220] The above first heater (530) may be, for example, a wire type heater.

[0221] The above heater (530, 535) may include a second heater (535, see FIG. 4) 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.

[0222] 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.

[0223] 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.

[0224] The above first tray wall (321) may include a portion where the second heater (535) is coupled.

[0225] In order to manufacture transparent ice, it is necessary to supply cold to one side of the tray assembly (e.g., the upper side) and operate a heater to the other side of the tray assembly (e.g., the lower side).

[0226] For example, the supply of cold may be made through the opening (324) of the first tray (300), and the supply of heat from the heater may be made through the first heater (530).

[0227] 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.

[0228] 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).

[0229] 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).

[0230] 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.

[0231] 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.

[0232] 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.

[0233] 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).

[0234] In the present embodiment, since the second tray (400) can be deformed by being pressed by the second pusher (540), the hardness of the second tray (400) can be lower than the hardness of the first tray (300) so that the shape of the second tray (400) can be easily deformed.

[0235] 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.

[0236] The above multiple tray parts can be arranged in a row in one direction (e.g., in the X-axis direction).

[0237] The above first tray (300) can form an upper tray.

[0238] 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).

[0239] 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.

[0240] The second tray (400) may include a second tray wall (410) forming the second cell (411a).

[0241] The first extension wall (420, see FIG. 8) of the second tray (400) can extend in a first direction (e.g., horizontal direction) from one end (e.g., upper end) of the second tray wall (410).

[0242] The second tray (400) may include a peripheral wall (430) extending in one direction (e.g., upward) from the second tray wall (410) and surrounding at least a portion of the first tray wall (321). The peripheral wall (430) may protrude in one direction (e.g., upward) from the first extension wall (420).

[0243] By configuring the second tray (400), it is possible to reduce water supplied to the cell from leaking between the first tray assembly and the second tray assembly during the process of the second tray (400) moving from the water supply position to the ice-making position. In addition, it is possible to reduce water expanding during the ice-making process from leaking between the first tray assembly and the second tray assembly and freezing.

[0244] A recessed portion (412) may be formed at one end (e.g., 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.

[0245] The above ice maker (200) may include a driving device (500) that provides driving force. For example, the driving device (500) may be manually driven.

[0246] The second tray (400) can move relative to the first tray (300) by receiving the driving force of the above driving device (500).

[0247] The ice maker (200) may include a shaft (580) that passes through the through hole (455a) of the second tray supporter (450). The shaft (580) extends between the two extension parts (455) and can be moved by receiving driving force from the driving device (500).

[0248] The above driving device (500) may include a driving case (510) forming an exterior and a lever (550) connected to the driving case (510) and operable by a user.

[0249] The above lever (550) may include a protrusion (554) that is connected to the first surface of the drive case (510) and is provided on the second surface to be movable according to the movement of the lever (550). For example, the protrusion (554) may be provided to be rotatable.

[0250] For example, the first side and the second side may form faces facing each other, i.e., opposite sides.

[0251] The above protrusion (554) can protrude from the second surface.

[0252] For example, the lever (550) may be rotatable. However, the lever (550) is not limited to being rotatable and may be provided to be movable, such as moving in a straight line.

[0253] The above protrusion (554) can be connected to the driving connection (462) of the arm (460). The protrusion (554) rotates according to the movement of the lever (550), and the driving connection (462) can move together with the protrusion (554).

[0254] The above drive case (510) may include a gear assembly (520) that is coupled with the lever (550). The gear assembly (520) may constitute a reduction gear assembly.

[0255] The above gear assembly (520) can be accommodated inside the drive case (510).

[0256] The gear assembly (520) may include a first gear (521) coupled to a connecting portion (553) of the lever (550). The connecting portion (553) may pass through the drive case (510) and be coupled to the center of the first gear (521).

[0257] The above first gear (521) can constitute a driving gear.

[0258] The above gear assembly (520) may include a second gear (523) that is coupled with the first gear (521). The second gear (523) may constitute a first driven gear.

[0259] The second gear (523) may be larger than the first gear (521) and may have more gear teeth than the first gear (521). In the process of transmitting power from the first gear (521) to the second gear (523), the rotational speed of the gear may decrease.

[0260] A gear shaft (524) forming a center of rotation of the second gear (523) is provided at the center of the second gear (523), and the gear shaft (524) can be rotatably supported on the drive case (510).

[0261] The above gear assembly (520) may include a third gear (525) that is coupled with the second gear (523). The third gear (525) may constitute a second driven gear.

[0262] The third gear (523) may be larger than the second gear (523) and may have more gear teeth than the second gear (523). In the process of transmitting power from the second gear (523) to the third gear (525), the rotational speed of the gear may decrease.

[0263] The protrusion (554) may be connected to the center of the third gear (525). The protrusion (554) may be centrally connected to the third gear (523) and may protrude outward through the gear body (510).

[0264] By configuring the gear assembly (520) as described above, the reduced rotational force can be transmitted to the arm (460) in conjunction with the movement of the lever (550).

[0265] Although the drawing shows the gear assembly (520) as being composed of three gears, the number of gears is not limited to three in the spirit of the present invention, and a gear assembly composed of two or four or more gears may be provided.

[0266] FIG. 8 is a drawing showing a tray according to a first embodiment of the present invention in an ice-making position, FIG. 9 is a cross-sectional view taken along line 9-9 of FIG. 8, FIG. 10 is a drawing showing a tray according to a first embodiment of the present invention in a water supply position, FIG. 11 is a cross-sectional view taken along line 11-11 of FIG. 10, FIG. 12 is a drawing showing a tray according to a first embodiment of the present invention in an ice-making position, and FIG. 13 is a cross-sectional view taken along line 13-13 of FIG. 12.

[0267] First, referring to FIGS. 8 and 9, the ice maker (200) may be in an ice-making position in which the first tray (300) and the second tray (400) are closed.

[0268] The above ice-making position can be understood as a reference position of the ice maker (200) in which the second part (552) of the lever (550) is in a first direction (e.g., horizontal direction). At this time, the lever (550) can also be understood as being in the reference position.

[0269] At the above reference position, the second part (552) of the lever (550) may be in a position parallel to one surface (e.g., the upper surface) of the drive case (510). At this time, the lever (550) is defined as being in a 0 degree state.

[0270] In the above ice-making position, the lever (550) can be operated to move the ice maker to the water supply position as shown in FIGS. 10 and 11. The lever (550) can be operated to move in a forward direction (counterclockwise with reference to FIG. 10) with respect to the connecting portion (553) in the ice-making position of FIG. 8.

[0271] For example, the lever (550) may be operated to be rotatable. The lever (550) may be rotated at least once. At this time, the second part (552) may be positioned at a downward angle with respect to one surface (e.g., the upper surface) of the drive case (510).

[0272] The first angle (θ1) between the second part (552) and one surface (e.g., the upper surface) of the drive case (510) may be 0 degrees or more and 90 degrees or less. That is, the user can rotate the lever (550) by 360 degrees or more and 450 degrees or less.

[0273] In order for the user to easily recognize the water supply position of the ice maker, the drive case (510) may be provided with an indicator indicating the water supply position and guide information for moving to the water supply position.

[0274] Due to the deceleration effect of the gear assembly (520), the second tray (400) can move by a relatively small angle. For example, the second tray (400) can rotate by about 20 to 25 degrees in the counterclockwise direction.

[0275] Accordingly, even if the user moves the lever within a certain range rather than moving it by an exact angle, the second tray (400) can move to a position where water can be supplied.

[0276] Depending on the gear arrangement of the above gear assembly (520), the reduction size of the second tray (400) can be adjusted.

[0277] At the above water supply location, the user can supply water by attaching a water cup (C) containing water to the water supply guide (240).

[0278] When the preset amount of water supply through the above water cup is completed, the water can be supplied by spreading from one cell (360) to another cell (360) after waiting for a preset period of time. At this time, the water can flow along the peripheral wall (430) of the second tray (400).

[0279] 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).

[0280] Once the supply is complete, the user can move the lever (550) in the reverse direction (clockwise as shown in FIG. 8). For example, the user can move the lever (550) in the reverse direction until resistance is felt as the first and second trays (300, 400) contact each other at the ice-making position.

[0281] Due to the reverse movement of the above lever (550), the second tray (400) can return to the ice-making position as shown in FIG. 8.

[0282] In order for the user to easily recognize the ice-making position of the ice maker, the drive case (510) may be provided with an indicator indicating the ice-making position and guide information for moving to the ice-making position.

[0283] A user can input an ice-making command through the input unit provided on the display (201). When the ice-making command is input, the first heater (530) is driven to perform ice-making to produce transparent ice.

[0284] When the above ice making is completed, information indicating that the ice making is completed can be output through the display (201).

[0285] Once the ice making is complete, the user can perform the ice removal operation.

[0286] As shown in FIGS. 12 and 13, the lever (550) can be operated to move the ice maker from the ice-making position of FIG. 8 to the ice-breaking position.

[0287] The above lever (550) can be operated to move in a forward direction (counterclockwise based on FIG. 12) based on the connection part (553) at the ice-making position of FIG. 8.

[0288] For example, the lever (550) may be rotated at least 5 turns. At this time, the second part (552) may be in a downwardly inclined position with respect to one surface (e.g., the upper surface) of the drive case (510).

[0289] The second angle (θ2) between the second part (552) and one surface (e.g., the upper surface) of the drive case (510) may be greater than or equal to 180 degrees and less than or equal to 270 degrees. That is, the user may rotate the lever (550) by greater than or equal to 1,980 degrees and less than or equal to 2,070 degrees.

[0290] In order for the user to easily recognize the ice maker's ice-making position, the drive case (510) may be provided with an indicator indicating the ice maker's ice maker position and guide information for moving to the ice maker's ice maker position.

[0291] Due to the deceleration effect of the gear assembly (520), the second tray (400) can move by a relatively small angle. For example, the second tray (400) can move by approximately 110 to 120 degrees in a counterclockwise direction. Accordingly, even if the user does not rotate the lever by an exact angle but rotates it within a certain range, the second tray (400) can move to a position where it can be moved.

[0292] Depending on the gear arrangement of the above gear assembly (520), the reduction size of the second tray (400) can be adjusted.

[0293] 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 (e.g., downward).

[0294] The first pusher (700) can be lowered to a position inside the cell (360). The bar (720) of the first pusher (700) can be at a position passing through the opening (324).

[0295] As the first pusher (700) moves, the ice (I) can be separated from the first tray (300) by being pressed by the first pusher (700).

[0296] One end (e.g., the lower end) of the second tray (400) can be deformed by contact with the pusher (540). Ice in the second tray (400) can be separated from the second tray (400) by the pressure of the pusher (540).

[0297] The moving position of the second tray (400) shown in Fig. 12 can be called the “maximum moving position.”

[0298] The second tray (400) may be formed of a flexible or ductile material that can be deformed when pressed by the second pusher (540).

[0299] During the ice-making process, at least one of the first heater (530) and the second heater (535) may be driven to assist in the ice-making process. Ice separated from the second tray (400) may fall and be stored in the ice bin (600).

[0300] Once the ice-making is complete, the user can move the lever (550) in the reverse direction (clockwise as shown in FIG. 12). For example, the user can move the lever (550) in the reverse direction until resistance is felt as the first and second trays (300, 400) contact each other at the ice-making position.

[0301] Hereinafter, other embodiments of the present invention will be described. These other embodiments differ from the first embodiment only in some configurations, so the description will focus on the differences, and for the same parts as the first embodiment, the description and drawing references of the first embodiment will be used.

[0302] FIG. 14 is a top perspective view showing the configuration of an ice maker according to a second embodiment of the present invention, FIG. 15 (a) is a drawing showing the appearance of a lever in an ice-making position of an ice maker according to a second embodiment of the present invention, FIG. 15 (b) is a drawing showing the appearance of a lever in an ice-making position of an ice maker according to a second embodiment of the present invention being caught by a stopper, FIG. 15 (c) is a drawing showing the appearance of a lever in a water supply position of an ice maker according to a second embodiment of the present invention being caught by a stopper, and FIG. 15 (d) is a drawing showing the appearance of a lever in an ice-separating position of an ice maker according to a second embodiment of the present invention.

[0303] First, referring to FIG. 14, an ice maker (200a) according to a third embodiment of the present invention may include a driving device (500a) that provides driving force to move the position of the ice maker. The driving device (500a) may be a manually driven driving device.

[0304] The above driving device (500a) may include a driving case (510) in which a gear assembly (520) is provided. The description of the gear assembly (520) refers to the description of the first embodiment.

[0305] The above driving device (500a) may include a user-operable lever (550a).

[0306] The above lever (550a) may be configured as a knob type lever, for example.

[0307] In the above drive case (510), a recessed portion (515) in which the lever (550a) is positioned can be formed. The recessed portion (515) is recessed in the outer surface of the drive case (510), and the lever (550a) can be inserted into the recessed portion (515).

[0308] The above driving device (500a) may include a stopper (556) for fixing the position of the lever (550a). The stopper (556) may be movably coupled to the lever (550a).

[0309] For example, the stopper (556) may be coupled to the lever (550a) and may be provided to be slidable in the outward direction of the lever (550a).

[0310] When operating the above lever (550a), the stopper (556) may be in a state where it is inserted into the lever (550a). On the other hand, when the lever (550a) is moved to a predetermined position, i.e., a water supply position, an ice-making position, or an ice-separating position, the stopper (556) may be pulled out of the lever (550a) to fix the position of the lever (550a).

[0311] The above driving device (500a) may include a catch (570) that engages with the stopper (556). The catch (570) may be located on one side (e.g., a side) of the lever (550a). For example, the catch (570) may include a catch rib or a catch bracket.

[0312] The above-mentioned catch (570) includes a groove (573) in which at least a portion of the stopper (556) is received, and on both sides of the groove may include catch protrusions (571, 572) that interfere with the stopper (556).

[0313] The above-mentioned catches (571, 572) may include a first catch (571) and a second catch (572). The groove (573) may be formed between the first and second catches (571, 572).

[0314] Figure 15 (a) shows the arrangement of the lever (550a) and the gear assembly (520) when the ice maker (200a) is in the ice-making position (see Figure 8), which is the reference position.

[0315] In the above ice-making position, the lever (550a) may be arranged in a first direction (e.g., horizontally). To distinguish the left and right ends of the lever (550a), an indicator "A" may be displayed on the left end, and "B" may be displayed on the right end. However, the symbol display of the indicator is not limited thereto.

[0316] The above ice-making position may be a state in which the first tray (300) and the second tray (400) come into contact and move slightly further in the reverse direction when the user turns the lever (550a) all the way in the reverse direction (clockwise as shown in FIG. 15a). At this time, the spring (470) may be tensioned by a predetermined length, so that the first and second trays (300, 400) may be in close contact.

[0317] Figure 15 (b) shows a user pulling out the stopper (556) from the lever (550a) and connecting it to the catch (570) to fix the ice-making position.

[0318] The stopper (556) can be pulled out by sliding to one side (e.g., side) of the lever (550a). The portion of the stopper (556) pulled outward from the lever (550a) can be caught by the catch (570). For example, the pulled-out portion can be inserted into the groove (573) and interfere with the first and second catch protrusions (571, 572).

[0319] By the stopper (556) being caught by the catch (570), the first and second trays (300, 400) can be maintained in close contact at the ice-making position.

[0320] (c) of Fig. 15 shows the state in which the lever (550a) is moved in the forward direction (counterclockwise based on (c) of Fig. 15) from the ice-making position of Fig. 15 (a) to the water supply position (see Fig. 10).

[0321] For example, the lever (550a) can move 180 degrees in a forward direction while in the ice-making position. Guide information may be provided to the drive case (510) to indicate that it should move 180 degrees counterclockwise to move to the ice-making position.

[0322] For example, when the lever (550a) rotates 1 / 2 (rotates by 180 degrees), the second tray (400) can be rotated by about 20 degrees and moved to the water supply position by the deceleration of the gear assembly (520).

[0323] However, the rotation angle when moving to the water supply position is not limited thereto, and the movement angle of the lever (550a) and the movement angle of the second tray (400) according to the movement of the lever (550a) may be adjusted differently by adjusting the reduction ratio of the gear assembly (520).

[0324] With the ice maker moved to the water supply position, the user can perform a water supply operation by engaging the stopper (556) with the catch (570) and using the water cup (C). By engaging the stopper (556), movement of the tray assembly can be prevented during the water supply process.

[0325] (d) of Fig. 15 shows the state in which the lever (550a) is moved in the forward direction (counterclockwise based on (d) of Fig. 15) from the ice-making position of (a) of Fig. 15 to the ice-breaking position (see Fig. 12).

[0326] For example, the lever (550a) can be rotated 5 times (1,800 degrees) while in the ice-making position. Guide information indicating that the drive case (510) should be rotated 1,800 degrees counterclockwise to move to the ice-making position can be provided.

[0327] When the above lever (550a) rotates 5 times (rotates by 1,800 degrees), the second tray (400) can move by about 115 degrees to the water supply position by the deceleration of the gear assembly (520).

[0328] However, the rotation angle when moving to the above-mentioned moving position is not limited thereto, and the movement angle of the lever (550a) and the movement angle of the second tray (400) according to the movement of the lever (550a) may be differently adjusted by adjusting the reduction ratio of the gear assembly (520).

[0329] When the ice maker has moved to the freezing position, the user can attach the stopper (556) to the catch (570) and maintain the freezing position for a certain period of time.

[0330] By this configuration and operation, the state of a specific position of the lever or ice maker can be easily maintained without the user having to continue to hold the lever after manually operating the lever.

[0331] Fig. 16 is a cross-sectional view showing the configuration of an ice maker according to a second embodiment of the present invention, and Fig. 17 is a cross-sectional view showing a tray being fixed in position by a stopper at an ice-making position of the ice maker of Fig. 16.

[0332] Referring to FIGS. 16 and 17, the ice maker according to the second embodiment of the present invention may include a stopper (440) provided on the tray assembly side in addition to a stopper (556) provided on the lever side.

[0333] The above stopper (556) may be called a “lever stopper,” “external stopper,” or “first stopper” in that it is provided on the side of the lever (550) operated by the user. The above stopper (440) may be called a “tray-side stopper,” “internal stopper,” or “second stopper.”

[0334] The stopper (440) may be provided on the second tray (400). For example, the stopper (440) may be provided on the second tray wall (410) and configured to protrude from the second tray wall (410).

[0335] At least a portion of a bracket (220a) is positioned on the side of the second tray (400), and the bracket (220a) may include a catch member (230) that catches the stopper (440).

[0336] The above bracket (220a) has a configuration corresponding to the bracket (220) described in the first embodiment and can be combined to at least one side of the storage room.

[0337] The above-mentioned hanging member (230) may be supported by the bracket (220a) and may have a shape extending in one direction (e.g., up and down).

[0338] The above-mentioned hook member (230) may be connected to the support wall (229a, 229b) of the bracket (220a). The support wall (229a, 229b) may extend in a first direction (e.g., horizontal direction) and may include a first support wall (229a) that constitutes a part of the wall (e.g., upper wall) of the bracket (220a).

[0339] The above support walls (229a, 229b) may include a second support wall (229b) extending in one direction (e.g., downward) from the first support wall (229a).

[0340] The above-mentioned catch member (230) may be provided on the second support wall (229b). For example, the catch member (230) may be attached to the inner surface of the second support wall (229b).

[0341] The above-mentioned hooking member (230) may be composed of an elastic material or a flexible material that can be deformed. For example, the above-mentioned joining member (230) may be composed of rubber, silicone, or a soft synthetic resin.

[0342] The stopper (440) can press the engaging member (230) while interfering with the engaging member (230). The engaging member (230) can be deformed by the pressing of the stopper (440) and form a groove that accommodates a portion of the stopper (440). The stopper (440) can be combined while being inserted into the groove of the engaging member (230).

[0343] The stopper (440) can be maintained in a state of being coupled to the catch member (230) at the water supply position or ice making position of the ice maker.

[0344] For example, the force (frictional force) that binds the stopper (440) to the engaging member (230) may be greater than the force due to the weight of the water and tray assembly during the water supply process.

[0345] In addition, the force (frictional force) by which the stopper (440) is coupled to the catch member (230) may be greater than the restoring force by the spring (470) during the ice-making process.

[0346] In the ice-making position of the above ice maker, the stopper (440) can be separated from the catch member (230).

[0347] Meanwhile, the force (frictional force) by which the stopper (440) is coupled to the engaging member (230) may be smaller than the force with which the user moves the lever (550). That is, when the user moves the lever (550), the stopper (440) may be released from the engaging member (230).

[0348] Fig. 16 shows the stopper (440) being fixed to the first point (P1) of the catch member (230) at the water supply position of the ice maker.

[0349] Fig. 17 shows the ice maker in an ice-making position, with the stopper (440) fixed at the second position (P2) of the catch member (230). For example, the second position (P2) may be formed at a higher position than the first position (P1).

[0350] FIG. 18 is a drawing showing a part of a configuration of an ice maker according to a third embodiment of the present invention, and FIG. 19 is a drawing showing a stopper interfering with a support wall of an ice maker according to a third embodiment of the present invention.

[0351] Referring to FIGS. 18 and 19, the ice maker (200b) according to the third embodiment of the present invention may include a stopper (440b) as a “tray-side stopper.”

[0352] The above stopper (440b) may be provided on the arm (460).

[0353] The above stopper (440b) is provided on the female body (461) of the female body (460) and can protrude laterally from the female body (461).

[0354] The above stopper (440b) can move together with the arm (460) during the process of moving the position of the ice maker.

[0355] At least a portion of a bracket (220b) may be positioned on the side of the second tray (400). The bracket (220b) has a configuration corresponding to the bracket (220) described in the first embodiment and may be coupled to at least one side of the storage room.

[0356] The above bracket (220b) may include a catch member (230b) that catches the stopper (440b). The description of the catch member (230b) refers to the description of the catch member (230) of the second embodiment.

[0357] The above-mentioned hook member (230b) may be connected to the support wall (229a, 229b) of the bracket (220b). The support wall (229a, 229b) may extend in a first direction (e.g., horizontal direction) and may include a first support wall (229a) that constitutes a part of the wall (e.g., upper wall) of the bracket (220a).

[0358] The above support walls (229a, 229b) may include a second support wall (229b) extending in one direction (e.g., downward) from the first support wall (229a).

[0359] The above-mentioned catch member (230b) may be provided on the second support wall (229b). For example, the catch member (230b) may be attached to the inner surface of the second support wall (229b).

[0360] The above stopper (440b) can press the engaging member (230b) while interfering with the engaging member (230b). The engaging member (230b) can be deformed by the pressing of the stopper (440b) and form a groove that accommodates a portion of the stopper (440b). The stopper (440b) can be combined while being inserted into the groove of the engaging member (230b).

[0361] At the water supply position or ice making position of the ice maker, the stopper (440b) can be maintained in a state of being coupled to the catch member (230b).

[0362] FIG. 20 is an exploded perspective view showing the configuration of an ice maker according to a fourth embodiment of the present invention, FIG. 21 is a cross-sectional view showing the configuration of the ice maker of FIG. 20, and FIG. 22 is a drawing showing a stopper interfering with a support wall of the ice maker of FIG. 20.

[0363] Referring to FIGS. 20 to 22, an ice maker (200c) according to a fourth embodiment of the present invention may include a first tray (300) and a second tray (400).

[0364] 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).

[0365] Each tray part can form at least part of one cell.

[0366] 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).

[0367] The second tray cover (480) may include a cover wall (481) forming an opening (482). The opening (482) may be formed such that at least a portion of the second tray cover (480) passes through the opening so that at least a portion of the second tray (400) passes through the opening.

[0368] At least a portion of the second tray supporter (450) may be positioned on the other side (e.g., the lower side) of the second tray (400).

[0369] The second tray supporter (450) can support the second tray (400) on the other side (e.g., the lower side) of the second tray (400). For example, at least a portion of a wall forming a second cell of the second tray (400) can be supported by the second tray supporter (450).

[0370] The above ice maker (200) may include a lift (560) as a contact mechanism to increase the contact between the first tray assembly and the second tray assembly. The lift (560) may be understood as a contact mechanism that moves or rotates around the center of the shaft (580) so that the second tray assembly can be contacted with the first tray (300).

[0371] The above lift (560) is coupled to the shaft (580) and the holder (531, 532), so that the lift (560) can move or rotate together with the shaft (580) and the holder (531, 532).

[0372] The above shaft (580) can be coupled to the driving device (500). It can be coupled to the protrusion (554) of the driving device (500). The description of the driving device (500) refers to the description of the driving device (500) of the first embodiment.

[0373] The above lifts (560) may be provided in multiple numbers on both sides of the shaft (580). The multiple lifts (560) may be located on the outer sides of both side walls of the second tray supporter (450).

[0374] The above lift (560) may include a support bar (561) that supports a portion (e.g., a lower portion) of the second tray (400). The support bar (561) may be placed on the outer side of the side wall of the second tray supporter (450).

[0375] The above lift (560) may include an extension portion (563) coupled to the holder (531, 532). The extension portion (563) may form a first through hole (564) into which the holder (531, 532) is inserted.

[0376] The above lift (560) may include a protrusion (566) protruding from the support bar (561) in a direction toward the second tray (400). The protrusion (566) may press one surface (e.g., the bottom surface) of the second tray (400) to bring the second tray (400) into close contact with the first tray (300).

[0377] At the ice-making position of the tray assembly, the lift (560) can move further in one direction (for example, upward) based on the axis of the shaft (580) so that the second tray (400) is brought into close contact with the first tray (300).

[0378] In this process, the protrusion (566) provides a force to the second tray (400) toward the first tray (300), and the second tray (400) can transmit a force to one side (e.g., upward) to the second tray cover (480).

[0379] The holder may include a first holder (531) that is axially coupled to the driving unit (510) as a driving holder. The first holder (531) may be coupled to a first end of the shaft (580). An insertion hole into which the first holder (531) is inserted may be formed in the first end of the shaft (580).

[0380] The holder (530) may include a second holder (532) coupled to the second end of the shaft (580) as a driven holder. An insertion hole into which the second holder (532) is inserted may also be formed in the second end of the shaft (580), i.e., the end opposite the first end.

[0381] The first holder (531) or the second holder (532) may include an insertion bar in the shape of a bar.

[0382] The first holder (531) or the second holder (532) may include a protrusion protruding from the insertion bar.

[0383] The insertion bar and the protrusion can move to a degree that they are inserted into the through hole (455a) of the second tray supporter, and the internal area of ​​the second through hole (455a) can be formed to be larger than the sum of the cross-sectional areas of the insertion bar and the protrusion. According to this configuration, the first holder (531) can be in a position where it can move further, i.e., a position where it can rotate, within the second through hole (455a).

[0384] The user can further move the lever (550) of the driving device (500) to further move the holder (531, 532) and the lift (560).

[0385] The above support bar (561) may extend in a direction intersecting with the extension direction of the shaft (580), for example, in the Y-axis direction, which is a vertical direction. The Y-axis direction may be referred to as the “length direction” of the second tray (400), and the X-axis direction may be referred to as the “width direction” of the second tray (400).

[0386] The above extension (563) forms one side (e.g., rear side) of the lift (560), and the support bar (561) can extend in one direction (e.g., forward) from the extension (563). The support bar (561) can move in one direction (e.g., up and down) based on the center of the extension (563).

[0387] The above protrusion (566) is provided on the support bar (561) and can come into contact with the second tray (400). For example, the protrusion (566) can protrude from one surface (e.g., the upper surface) of the support bar (561) in a direction toward the second tray (400).

[0388] The above protrusion (566) can press one side (e.g., the bottom side) of the tray protrusion (429) of the second tray (400) to bring the second tray (400) into close contact with the first tray (300).

[0389] When the holder (531, 532) moves further while the first tray (300) and the second tray (400) are in contact with each other and in the ice-making position, the lift (560) coupled to the holder (531, 532) can move further in the movement direction of the holder (531, 532).

[0390] The above lift (560) can move until the protrusion of the holder (531, 532) interferes with the end of the through hole (455a) of the second tray cover (450). At this time, the second tray cover (450) may not move. That is, the holder (531, 532) and the lift (560) may rotate inside the second through hole (455a).

[0391] The above protrusion (566) can move upward based on the center of the extension (563) or holder (531, 532) and pressurize one surface (e.g., the bottom surface) of the second tray (400).

[0392] During the pressurizing process, either the protrusion (566) or the second tray (400) may be deformed. For example, the protrusion (566) may be pressed against the second tray (400), and at this time, the second tray (400) may be deformed.

[0393] The above protrusions (566) may be provided in multiple numbers. Among the multiple protrusions (566), the first protrusion (566a) located close to the holder (531, 532) has a relatively large movement distance, and the first protrusion (566a) can press the first tray protrusion (429a).

[0394] On the other hand, the movement distance of the second protrusion (566b) located far from the holder (531, 532) among the plurality of protrusions (566) is relatively large, and the second protrusion (566b) can press the second tray protrusion (429b).

[0395] The above protrusion (566) presses one side (e.g., the bottom side) of the tray protrusion (429) and can provide force to the second tray (400) toward the first tray (300) through the tray protrusion (429). Accordingly, the second tray (400) transmits a force to press against the second tray cover (480) in one direction (e.g., upward), and the second tray (400) can press against the first tray (300).

[0396] The above tray protrusion (429) is located inside the protrusion receiving portion (486) of the second tray cover (480), and during the deformation process of the second tray (400), the tray protrusion (429) can come into contact with the protrusion receiving portion (486).

[0397] Since one side (e.g., the upper side) of the protrusion receiving portion (486) is supported by the stopper (250), when the second tray (400) transmits a force to be pressed against the second tray cover (480) in one direction (e.g., upward), one side (e.g., the upper side) of the protrusion receiving portion (486) can act as a fixed support surface by the stopper (250). That is, the second tray (400) can be pressed against the first tray (300) through the fixed support surface.

[0398] Either of the two lifts (560) may include a stopper (440c) as a “tray side stopper”.

[0399] The above stopper (440c) is provided on the support bar (561) and can protrude laterally from the support bar (561). The stopper (440c) can move together with the arm (460) during the process of moving the position of the ice maker.

[0400] At least a portion of a bracket (220c) may be positioned on the side of the second tray (400). The bracket (220c) has a configuration corresponding to the bracket (220) described in the first embodiment and may be coupled to at least one side of the storage room.

[0401] The above bracket (220c) may include a catch member (230c) that catches the stopper (440c). The description of the catch member (230b) refers to the description of the catch member (230) of the second embodiment.

[0402] The above-described hook member (230c) may be connected to the support walls (229a, 229b) of the bracket (220c). The support walls (229a, 229b) may include a first support wall (229a) that extends in a first direction (e.g., horizontally) and constitutes a portion of a wall (e.g., an upper wall) of the bracket (220a). The support walls (229a, 229b) may include a second support wall (229b) that extends in one direction (e.g., downward) from the first support wall (229a).

[0403] The above-mentioned catch member (230c) may be provided on the second support wall (229b). For example, the catch member (230c) may be attached to the inner surface of the second support wall (229b).

[0404] The above stopper (440c) can press the engaging member (230c) while interfering with the engaging member (230b). The engaging member (230c) can be deformed by the pressing of the stopper (440b) and form a groove that accommodates a portion of the stopper (440c). The stopper (440c) can be combined while being inserted into the groove of the engaging member (230c).

[0405] The stopper (440c) can be maintained in a state of being coupled to the catch member (230c) at the water supply position or ice making position of the ice maker.

[0406] The present invention relates to an ice maker and / or a refrigerator equipped with an ice maker, and has remarkable industrial applicability because a user can easily perform manual operation in at least one of the ice supply, ice making, and ice removal processes.
