Description

refrigerator

[0001] This specification relates to a refrigerator.

[0002] Typically, a refrigerator may include a cabinet having a storage compartment and a door for opening and closing the storage compartment.

[0003] The above storage room is surrounded by an insulating wall, and the interior of the storage room can be maintained at a temperature lower than the outside temperature. Depending on the temperature range of the storage room, the storage room may be referred to as a refrigerator or a freezer.

[0004] Typically, a refrigerator's freezer is equipped with an ice maker to produce ice. The ice maker collects water supplied from a water source or water tank in a tray, cools the water, and produces ice. The ice produced by the ice maker can be stored in an ice bin.

[0005] The ice stored in the ice bin can be discharged through a dispenser provided on the door, or the user can open the freezer door and access the ice bin to take out the ice from the ice bin.

[0006] A refrigerator is disclosed in Korean Patent Publication No. 10-2016-0136659, a prior art document.

[0007] A refrigerator of a prior art document comprises: a cabinet having a refrigerator compartment and a freezer compartment formed below the refrigerator compartment; a refrigerator compartment door, a pair of which are arranged on the left and right sides to open and close the refrigerator compartment, and an ice maker and a dispenser are provided on one side; a main water tank provided in the refrigerator compartment and cooling supplied water; a water purification device provided in the cabinet and purifying supplied water; a sub-water tank provided in the refrigerator compartment door and further cooling the supplied water; a water supply path connecting the water purification device, the main water tank, the sub-water tank, the dispenser, and the ice maker; and a branch valve provided on the water supply path of the refrigerator compartment door and allowing purified water to be selectively supplied to the dispenser or the ice maker.

[0008] However, in the case of the prior literature, since water is supplied from an external water source to the ice maker, there is a disadvantage in that a valve is required to control the flow of water.

[0009] In addition, there is a risk that the water may remain contaminated because the water is stagnant in the water supply line in situations where water is not supplied to the ice maker, such as when the ice bin where ice is stored is full or the valve is broken.

[0010] One embodiment provides a refrigerator capable of manually supplying water to an ice maker.

[0011] Optionally or additionally, one embodiment provides a refrigerator in which a water tank for receiving water to be supplied to an ice maker can be easily installed or removed by a user.

[0149] The ice maker (230) may further include a second pusher (390) to separate ice from the ice making cell (230a) during the freezing process. The second pusher (390) may pressurize the second tray (260).

[0150] The second pusher (390) may include a second column (392). The second column (392) may be formed in a bar shape. The second pusher (390) may further include an installation portion (394). For example, a plurality of second columns (392) may extend from the installation portion (394).

[0151] The above installation part (394) can be installed on the bracket (240) or on the first frame (410) or the second frame (450).

[0152] The ice maker (230) may further include a transmission unit (320) for transmitting the moving force of the second tray (260) or the driving force of the driving unit (290) to the first pusher (380). One side of the transmission unit (320) may be connected to the body (384) of the first pusher (380). The other side of the transmission unit (320) may be connected to the tray supporter (280).

[0153] In this embodiment, the first pusher (380) may be a movable pusher, and the second pusher (390) may be a fixed pusher.

[0154] The above ice making assembly (200) may further include a restriction member (360) to restrict the water tank (210) from being separated from the frame (400).

[0159] Fig. 6 (a) is a perspective view of a water tank according to the first embodiment as viewed from one side, Fig. 6 (b) is a perspective view of a water tank according to the first embodiment as viewed from the other side, and Fig. 7 is a cross-sectional view taken along line 7-7 of Fig. 6 (a).

[0160] Referring to FIGS. 6 and 7, the water tank (210) of the present embodiment may include a first body (211) that forms a space (211a) in which water is received. The water tank (210) may include a second body (216) coupled to the first body (211).

[0161] With reference to Fig. 7, the first body (211) may include a lower opening. The second body (216) may cover the lower opening.

[0162] The above second body (216) may include a plane or may be rounded to be convex downward.

[0163] The second body (216) may include a discharge hole (217) through which water is discharged. The discharge hole (217) may be located, for example, at the center of the second body (216). By turning over the first body (211) while separating the second body (216) from the first body (211), water may be accommodated in the space (211a). Alternatively, it is also possible to supply water to the space (211a) through the discharge hole (217) without separating the second body (216) from the first body (211).

[0164] The above space (211a) can accommodate water sufficient to make ice once in the ice maker (230). For example, the volume of the above space (211a) can be equal to or similar to the sum of the volumes of a plurality of ice-making cells (230a).

[0165] Accordingly, when ice making is performed once in the ice maker (230), since there is no water in the water tank (210), a phenomenon such as contamination of the water in the water tank (210) can be prevented.

[0166] The second body (216) may further include an air hole (218). Air may be introduced into the space (211a) through the air hole (218). Water in the space (211a) may be easily discharged through the discharge hole (217) due to the air present in the space (211a).

[0167] The second body (216) may be combined in a form that surrounds a portion of the lower side of the first body (211). A sealer (219) that prevents water leakage may be provided at a contact surface between the first body (211) and the second body (216). For example, a groove (215) in which the sealer (219) is seated may be formed on the outer surface of the first body (211). For example, a ring-shaped sealer (219) may be seated in the groove (215) to surround the outer surface of the first body (211).

[0168] The water tank (210) may further include a flange (212). For example, the flange (212) may be provided along the perimeter of the first body (211). The flange (212) may be in contact with the first frame (410).

[0169] The above flange (212) may extend outward from the first body (211). For example, the flange (212) may extend horizontally from the upper portion of the first body (211).

[0170] The flange (212) may include an inclined surface (212a). The inclined surface (212a) may act to ensure that the water tank (210) is mounted in the correct position during the mounting process of the water tank (210).

[0171] The above-mentioned inclined surface (212a) may be inclined upward as it goes toward the outside of the first body (211). The above-mentioned flange (212) may function to allow a user to easily hold the water tank (210).

[0172] The water tank (210) may further include a handle (213). The handle (213) may extend horizontally from the first body (211). For example, the handle (212) may extend from the flange (212).

[0173] At least a portion of the handle (213) may be rounded. For example, a portion of the handle (213) may be bent so as to be rounded downward.

[0174] The handle (213) may be provided with a coupling portion (214). When the restriction portion (360) is coupled to the coupling portion (214), separation of the water tank (210) may be restricted.

[0175] The above-mentioned connecting portion (214) may be provided at a position spaced apart from the end portion (213a) of the handle (213). The connecting portion (214) may extend downward from the lower surface of the handle (213).

[0176] Fig. 8 (a) is a perspective view of the first frame according to the first embodiment as viewed from one side, and Fig. 8 (b) is a perspective view of the first frame according to the first embodiment as viewed from the other side.

[0177] Fig. 9 (a) is a front view of the first frame according to the first embodiment, and Fig. 9 (b) is a plan view of the first frame according to the first embodiment.

[0178] Referring to FIGS. 8 and 9, the first frame (410) according to the present embodiment may include a receiving portion (411) in which the water tank (210) is received. The receiving portion (411) may be formed by a surface of the first frame (410) being sunken. For example, the receiving portion (411) may be formed by a portion of the upper surface (410b) of the first frame (410) being sunken downward.

[0179] The first frame (410) may further include a flange groove (412) in which a flange (212) of the water tank (210) is received. The flange groove (412) may extend outward from the receiving portion (411). One surface of the flange groove (412) may include an inclined surface (see 412b of FIG. 13). The inclined surface (212a) of the flange (212) may be seated on the inclined surface (412b).

[0180] A through hole (413) may be formed in the bottom (411a) of the receiving portion (411). When the water tank (210) is received in the receiving portion (411), a portion of the water tank (210) may pass through the through hole (413). Alternatively, water discharged from the water tank (210) may pass through the through hole (413). The diameter of the through hole (413) may be larger than the diameter of the discharge hole (217).

[0181] A protrusion (411b) may be formed on the above-mentioned bottom (411a). For example, a plurality of protrusions (411b) may be spaced apart and arranged along the circumference of the through hole (413). The second body (216) of the water tank (210) accommodated in the accommodation portion (411) may be spaced apart from the bottom (411a) by the protrusions (411b).

[0182] The first frame (410) may further include a space (416) provided on one side of the receiving portion (411). The space (416) may provide a space in which the actuator may be positioned. The space (416) may provide a space in which the limiting portion (360) may be positioned.

[0183] A slot (415) may be formed in the wall (411c) forming the above-mentioned receiving portion (411) to allow the space portion (416) and the receiving portion (411) to communicate with each other.

[0184] The first frame (410) may further include a storage section (422) in which items can be stored. The storage section (422) may be located outside the receiving section (411).

[0185] For example, the storage unit (422), the receiving unit (411), and the space unit (416) may be arranged in a row. At least a portion of the receiving unit (411) may be positioned between the storage unit (422) and the space unit (416).

[0186] The first frame (410) may further include a cold air hole (419) for cold air to pass through. The ice maker (230) may be positioned in the space formed by the first frame (410), and cold air from the freezer (12) may flow toward the ice maker (230) through the cold air hole (419).

[0187] The first frame (410) may include a first surface (410a) facing the freezer (12) when the freezer door (25) is closed. A plurality of cold air holes (419) may be provided on the first surface (410a). A plurality of cold air holes (419) may be arranged in a horizontal direction. A plurality of cold air holes (419) may also be arranged in a vertical direction.

[0188] The first frame (410) may further include a coupling portion (423, 424) for coupling with the second frame (450). For example, a plurality of coupling portions (423, 424) may extend from the first frame (410) at spaced locations. The plurality of coupling portions (423, 424) may include a first coupling portion (423) and a second coupling portion (424).

[0189] The first frame (410) may include one or more step portions (427a, 427b). Interference between the first frame (410) and the door liner (102) may be prevented by the step portions (427a, 427b). The number and shape of the step portions (427a, 427b) may vary depending on the shape of the door liner (102).

[0190] For example, the step portions (427a, 427b) may include a first step portion (427a) positioned lower than the upper surface (410b) of the first frame (410), and a second step portion (427b) positioned lower than the first step portion (427a).

[0191] FIG. 10 (a) is a drawing showing a sensing unit and a moving unit installed in a first frame according to the first embodiment, FIG. 10 (b) is a drawing showing a mounting unit of the first frame, and FIG. 10 (c) is a perspective view showing a moving unit according to the first embodiment.

[0192] Referring to Fig. 10, the sensing unit (440) may be installed in the first frame (410). The sensing unit (440) may be installed at a position spaced apart from the wall (411c) forming the receiving portion (411). The first frame (410) may include a fastening boss (429) to which the sensing unit (440) is fastened. For example, a fastening member may pass through the sensing unit (440) and be fastened to the fastening boss (429).

[0193] The first frame (410) may include a mounting portion (425) for mounting the movable portion (430). The mounting portion (425) may be positioned between the wall (411c) and the detection portion (440).

[0194] The above mounting portion (425) may extend from the wall (411c) or from the upper surface (410b) of the first frame (410).

[0195] The above movable part (430) can be rotatably mounted on the mounting part (425). The mounting part (425) can include a coupling slot for coupling a part of the above movable part (430).

[0196] The above movable part (430) may include a body (431) and an extension part (433) extending from the body (431).

[0197] The above extension (433) may, for example, extend from each of both sides of the body (431).

[0198] The above extension (433) may include a first part (434) extending from the body (431) and a second part (435) extending from the first part (434). The diameter of the second part (435) may be larger than the diameter of the first part (434).

[0199] The above-mentioned coupling slot may, for example, extend upward from the bottom of the mounting portion (425).

[0200] The above-mentioned combination slot may include a first slot portion (425a), a second slot portion (425b), and a third slot portion (425c). The second slot portion (425b) may be located between the first slot portion (425a) and the third slot portion (425c).

[0201] For example, the first slot portion (425a) may be positioned below the second slot portion (425b). The width of at least a portion of the first slot portion (425a) may decrease toward the second slot portion (425b). The width or diameter of the third slot portion (425c) may be greater than the width of the second slot (425b).

[0202] The diameter of the first part (434) may be larger than the width of the second slot portion (425b). The diameter of the first part (434) may be smaller than the width or diameter of the third slot portion (425c). The diameter of the second part (435) may be larger than the width or diameter of the third slot portion (425c). The width of the first slot portion (425a) may be larger than the diameter of the first part (434).

[0203] The first slot portion (425a) can allow the first part (434) to be easily inserted. When an external force is applied so that the first part (434) is inserted into the second slot portion (425b), a portion of the mounting portion (425) is deformed, and the first part (434) moves along the second slot portion (425b) and then to the third slot portion (425c). After the first part (434) is moved to the third slot portion (425c), the deformed portion of the mounting portion (425) returns to its original shape.

[0204] In a state where the first part (434) is moved to the third slot part (425c), the movable part (430) can rotate around the first part (434). That is, the first part (434) provides a center of rotation of the movable part (430).

[0205] In a state where the water tank (210) is separated from the receiving portion (411), a part of the body (431) of the movable portion (430) may be positioned in the receiving portion (411). An opening (412a) may be formed in the wall (411c) for a part of the body (431) to pass through.

[0206] When the water tank (210) is separated from the receiving portion (411), the body (430) may include an inclined surface (431a). The inclined surface (431a) may be positioned in the receiving portion (411). In the process of mounting the water tank (210), the movable portion (430) may move from the initial position to the detection position.

[0207] When the water tank (210) is received in the receiving portion (411), if the water tank (210) presses the inclined surface (431a), the movable portion (430) rotates in one direction and moves from the initial position to the detection position, and the detection portion (440) can be turned on. When the detection portion (440) is turned on, the mounting of the water tank (210) can be detected.

[0208] When the water tank (210) is separated, the movable part (430) can be rotated in the other direction and returned to the initial position. Then, the detection part (440) can be turned off.

[0209] Fig. 11 (a) is a drawing showing a state in which a water tank is separated from a first frame according to the first embodiment, and Fig. 11 (b) is a drawing showing a state in which a restriction is separated from the first frame.

[0210] Fig. 12 (a) is a perspective view of a restriction according to the first embodiment as viewed from one side, Fig. 12 (b) is a perspective view of a restriction according to the second embodiment as viewed from the other side, and Fig. 13 is a cross-sectional view taken along line 13-13 of Fig. 3 (a).

[0211] Referring to FIGS. 11 to 13, the limiting member (360) can be rotatably installed on the first frame (410).

[0212] An installation groove (417) for installing the restriction part (360) may be formed in the first frame (410). The restriction part (360) may be positioned on the opposite side of the movable part (430) with respect to the receiving part (411).

[0213] The above-mentioned restriction (360) may include a body (361). A slot (417a) in which the body (361) can be positioned may be formed in the first frame (410).

[0214] The above-described limiting member (360) may include a shaft (362) extending from the body (361). The shaft (362) may provide a center of rotation of the above-described limiting member (360).

[0215] The shaft (362) may extend outward from the lower portion of the body (361). The shaft (362) may be inserted into the installation groove (417). To limit separation of the shaft (362) when it is inserted into the installation groove (417), the width of the entrance of the installation groove (417) may be smaller than the width of other parts.

[0216] The above-mentioned limiting portion (360) may further include a catch portion (363) extending to the body (361). The catch portion (363) may extend from the upper portion of the body (361).

[0217] The above-mentioned hook (363) can be hooked to the connecting portion (214) while the water tank (210) is accommodated in the receiving portion (411).

[0218] The above-described restriction (360) can move between a first position and a second position. When the water tank (210) is separated, the restriction (360) can be positioned at the first position (or release position). FIG. 11(a) illustrates the restriction (360) being positioned at the first position. When the water tank (210) is mounted, the restriction (360) can move to the second position (restriction position).

[0219] The above-described limiting member (360) may further include a stopper (364) extending from the body (361). The stopper (364) may limit further rotation of the limiting member (360) when the limiting member (360) is moved to the second position. The stopper (364) may come into contact with the first frame (410) when the limiting member (360) is moved to the second position.

[0220] Referring to Fig. 13, when the water tank (210) is accommodated in the receiving portion (411), the restricting portion (360) can be moved to the second position by the operation of the actuator. For example, the restricting portion (360) can be moved to the second position during the ice-making process after water supply is completed.

[0221] With the above-mentioned limiting portion (360) moved to the second position, the body (361) shields the slot (417a), and the engaging portion (363) is caught on the connecting portion (214) of the handle (213). The handle (213) can come into contact with the body (361).

[0222] When the water tank (210) is accommodated in the receiving portion (411), the upper surface of the water tank (210) can be positioned at the same height as the upper surface (410b) of the first frame (410). In this case, it is difficult for the user to hold the first body (211) other than the handle (213).

[0223] Depending on the position of the above-mentioned restriction (360), the gap between the above-mentioned restriction (360) and the above-mentioned handle (213) can be varied.

[0224] The user can hold the handle (213) and separate the water tank (210). When the handle (213) comes into contact with the body (361), there is no gap between the restriction portion (360) and the handle (213). In this case, no space is formed between the handle (213) and the body (361) for the user's finger to be inserted, making it difficult for the user to hold the handle (213).

[0225] In addition, even when attempting to separate the water tank (210) using a tool or the like, the catch (363) is connected to the connecting portion (214) of the handle (213), so separation of the water tank (210) can be prevented.

[0226] Meanwhile, the water tank (210) may further include an extension portion (217a) extending downward from the second body (216), and it is also possible for the discharge hole (217) to be formed in the extension portion (217a).

[0227] In this case, when the water tank (210) is accommodated in the receiving portion (411), the extension portion (217a) can pass through the through hole (413) of the receiving portion (411). The second body (216) of the water tank (210) can be spaced apart from the bottom (411a) of the receiving portion (411) by the protrusion (411b). In this case, even if water flows to the surface of the water tank (210) in the process of accommodating the water tank (210) in the receiving portion (411), the water that has flowed to the surface of the water tank (210) can be reduced from stagnating at the bottom (411a) of the receiving portion (411).

[0228] When the water tank (210) is accommodated in the receiving portion (411), at least a portion of the first body (211) can be spaced apart from the wall (411c). Therefore, the water tank (210) can be easily inserted into the receiving portion (411), and during the separation process, the water tank (210) can be easily separated from the receiving portion (411).

[0229] Fig. 14 (a) is a perspective view of a water supply guide according to the first embodiment as viewed from one side, and Fig. 14 (b) is a perspective view of a water supply guide according to the first embodiment as viewed from the other side. Fig. 15 is a cross-sectional view taken along line 15-15 of Fig. 14 (a).

[0230] Referring to FIGS. 13 to 15, the water supply guide (220) of the present embodiment may include a bottom wall (221). Water discharged through the discharge hole (217) of the water tank (210) may fall to the bottom wall (221). The bottom wall (221) may guide the fallen water toward the ice-making cell (230a).

[0231] The above water supply guide (220) may further include a peripheral wall (222) extending from the edge of the bottom wall (211). The bottom wall (221) and the peripheral wall (222) may define a guide path (220a).

[0232] The above water supply guide (220) may further include a through hole (224) through which water passes. The through hole (224) may be formed in the peripheral wall (222).

[0233] The above-described bottom wall (221) may include a first portion (221a). The first portion (221a) may face the bottom (411a) of the receiving portion (411). For example, at least a portion of the first portion (221a) may overlap the bottom (411a) of the receiving portion (411) in the vertical direction.

[0234] At least a portion of the first portion (221a) may overlap with the through hole (413) in the vertical direction. Accordingly, when the water tank (210) is accommodated in the receiving portion (411), the discharge hole (217) may overlap with the first portion (221a) in the vertical direction.

[0235] A portion of the peripheral wall (222) may be arranged to surround the wall (411c) of the receiving portion (411). At least a portion of the bottom (411a) of the receiving portion (411) may be positioned in the guide passage (220a). At least the discharge hole (217) in the water tank (210) may be positioned in the guide passage (220a). Accordingly, water discharged from the water tank (210) may fall directly into the first portion (221a).

[0236] The above-described bottom wall (221) may further include a second portion (221b) extending from the first portion (221a). The width of the second portion (221b) may be smaller than the width or diameter of the first portion (221a). Accordingly, the guide path (220a) may include a portion with a decreasing width.

[0237] The above-mentioned bottom wall (221) may further include a third portion (221c) extending from the second portion (221b). The third portion (221c) may extend roundly from the second portion (221b). The third portion (221c) may further include a downwardly sloping surface (221d) to facilitate the falling of water. The through hole (224) may be positioned at an end of the sloping surface (221d).

[0238] The above water supply guide (220) may further include a cover (228) that covers a portion of the guide path (220a). The cover (228) may cover the third portion (221c). The cover (228) may cover at least a portion of the second portion (221b). The cover (228) may limit water supplied to the guide path (220a) from overflowing from the guide path (220a).

[0239] The cover (228) may be coupled to the peripheral wall (222). A portion (228a) of the cover (228) may be inserted into the guide path (220a).

[0311] Figure 32 (a) is a drawing showing the ice maker at the water supply position of the second tray assembly, Figure 32 (b) is a drawing showing the ice maker at the ice making position of the second tray assembly, and Figure 32 (c) is a drawing showing the ice maker at the ice removal position of the second tray assembly. Figure 33 is a cross-sectional view taken along line 33-33 of Figure 3 (b).

[0312] Figure 33 shows the second tray assembly positioned in the ice-making position.

[0313] Referring to FIGS. 28 to 33, the driving unit (290) can be controlled by the control unit (600).

[0314] The above control unit (600) may be installed on or separated from the target for control. The control unit (600) may be located inside or outside the target for control.

[0315] For example, the control unit (600) may be provided in the cabinet (10) or in the freezer door (25).

[0316] The above control unit (600) may be located outside the above driving unit (290). The above control unit (600) may control the driving unit (290) alone, or may control other components in the refrigerator other than the driving unit (290).

[0317] The above ice maker (230) may include a first tray assembly (231a) and a second tray assembly (231b).

[0318] The first tray assembly (231a) may include the first tray (250). The second tray assembly (231b) may include the second tray (260), a tray cover (270), and a tray supporter (280).

[0319] The first tray (250) can form a first cell (251) that is part of the ice-making cell (230a). The second tray (260) can form a second cell (261) that is part of the ice-making cell (230a).

[0320] The above control unit (600) can control the driving unit (290) so that the second tray assembly (231b) (or the second tray) moves to the water supply position, ice-making position, and ice-breaking position.

[0321] The second tray assembly (231b) can move forward from the water supply position to the ice-making position. The forward direction is counterclockwise with reference to Fig. 32. The second tray assembly (231b) can move backward from the ice-making position to the water supply position in a direction opposite to the forward direction. The second direction is clockwise with reference to Fig. 32.

[0322] The second tray assembly (231b) can move in the reverse direction from the water supply position to the ice-free position. The second tray assembly (231b) can move in the forward direction from the ice-free position to the water supply position.

[0323] Water can be supplied from the water supply location of the second tray assembly (231b). Water discharged from the water tank (210) can be supplied to the ice-making cell (230a) through the water supply guide (220).

[0324] At the water supply position of the second tray assembly (231b), the water tank (210) can be accommodated in the receiving portion (411). The water tank (210) can be separated from the receiving portion (411) at the water supply position of the second tray assembly (231b).

[0325] The control unit (600) can determine whether the water supply of the ice-making cell (230a) is completed after the installation of the water tank (210) is detected. Whether the water supply is completed can be determined based on at least one of the detection time of the installation of the water tank (210) and the value detected by the sensor provided in the ice maker (230).

[0326] At the water supply position of the second tray assembly (231b), at least a portion of the second tray (260) may be spaced apart from the first tray (250). For example, the first cell (251) and the second cell (261) may be spaced apart.

[0327] In the water supply position of the second tray assembly (231b), the restriction part (360) can be positioned at the first position. Since the shaft (362) of the restriction part (360) is positioned at the lower side of the restriction part (360), the restriction part (360) can be rotated at a predetermined angle with respect to the vertical line by its own weight unless an external force is applied to the restriction part (360).

[0328] The second operating part (350) can support the rotated limiting part (360). The second operating part (350) tries to move downward due to its own weight, and the first operating part (340) supports the second operating part (350).

[0329] At the first position of the above-mentioned restriction portion (360) and the water supply position of the above-mentioned second tray assembly (231b), the contact portion (332) of the above-mentioned operating arm (330) can be in contact with or spaced apart from the above-mentioned first operating portion (340).

[0330] Once the water supply is complete, the second tray assembly (231b) can be moved to the ice-making position.

[0331] When the second tray assembly (231b) moves to the ice-making position, the first tray (250) and the second tray (260) can come into contact. In this state, a complete ice-making cell (230a) can be formed by the first cell (251) and the second cell (261). A portion of the water contained in the second tray (260) can be distributed to the first cell (251) of the first tray (250).

[0332] In the process of the second tray assembly (231b) moving to the ice-making position, the operating arm (330) can move. As the operating arm (330) moves in the forward direction, the contact portion (332) of the operating arm (330) can press the first operating portion (340). For example, the contact portion (332) can press the first part (341a) of the first operating portion (340) downward. Then, the first operating portion (340) can rotate, and the second part (341b) of the first operating portion (340) can rise.

[0333] When the second part (341b) rises, the second operating part (350) can rise. When the second operating part (350) rises, the second operating part (350) can rotate the limiting part (360). That is, the limiting part (360) can move from the first position to the second position. Accordingly, the engaging part (363) of the limiting part (360) can be coupled to the coupling part (214) of the handle (213). In this state, the separation of the water tank (210) can be restricted.

[0334] At the above ice-making position, an ice-making process can be performed. During the ice-making process, since the restriction (363) is maintained in the second position, separation of the water tank (210) can be restricted.

[0335] In the above ice-making process, the ice maker (230) may further include a transparent ice heater to produce ice with increased transparency. In the ice-making process, the transparent ice heater may be turned on. The transparent ice heater may supply heat to the ice-making cell (230a).

[0336] While the ice making process is being performed, it can be determined whether ice making is complete based on one or more of the values ​​detected by the sensor and the ice making time.

[0337] Once ice making is complete, a separation process may be performed. The separation process may include a heating process in which at least one of the separation heater and the transparent ice heater is operated. When the heater is turned on, the heat of the heater may be transferred to the ice making cell (230a). The heat of the heater may separate the ice from the first tray (250). The turning off of the heater may be determined based on at least one of the operating time of the heater and the temperature detected by the sensor.

[0338] The above-described moving process may further include a moving process in which the second tray assembly (231b) moves. The moving process may be performed after the heater is turned off, or the moving process may be performed while the heater is operating, and the heater may be turned off during the moving process.

[0339] In the above-described ice-making process, the second tray assembly (231b) can move in the reverse direction from the ice-making position toward the ice-making position.

[0340] During the above-described moving process, the second tray assembly (231b) may be moved in the reverse direction by receiving power from the driving unit (290) to move the full ice detection lever (330).

[0341] The full ice detection lever (330) may remain stationary until the second tray assembly (231b) is rotated in the reverse direction by a certain angle from the ice-making position. The full ice detection lever (330) may be rotated when the second tray assembly (231b) is rotated by more than the certain angle. At this time, the full ice detection lever (330) may be rotated in the reverse direction, which is the same direction as the rotational direction of the second tray assembly (231b).

[0342] When the second tray assembly (231b) is moved to the full ice detection position, the full ice detection lever (330) can also be moved to the full ice detection position.

[0343] When the second tray assembly (231b) is moved to the full ice detection position and full ice is not detected, the second tray assembly (231b) can be further moved in the reverse direction toward the ice detection position.

[0344] When the second tray assembly (231b) is further moved while the full ice detection lever (330) is moved to the full ice detection position, the full ice detection lever (330) can be moved in the forward direction and returned to the initial position.

[0345] Meanwhile, when the second tray assembly (231b) moves from the ice-making position to the ice-separating position, the operating arm (330) moves together, and the pressing force applied to the first operating part (340) may decrease. Then, the first part (341a) of the first operating part (340) may rise and the second part (341b) may descend. Accordingly, the second operating part (350) also descends. Then, the force applied to the limiting part (360) is removed, and the limiting part (360) may return from the second position to the first position.

[0346] As another example, at least one of the first operating portion (340), the second operating portion (350) and the limiting portion (360) is supported by an elastic member, and while the second tray assembly (231b) moves from the ice-making position to the ice-removing position, it is also possible for the limiting portion (360) to return from the second position to the first position by the elastic force of the elastic member.

[0347] In the process of the second tray assembly (231b) moving from the ice-making position to the ice-removing position, the first column (382) of the first pusher (380) can pressurize the ice in the ice-making cell (230a).

[0348] While the second tray assembly (231b) is moved to the moving position, the second column (392) of the second pusher (390) can press the second tray (260).

[0349] Ice separated from the second tray assembly (231b) can fall downward and be stored in the ice bin (480).

[0350] After the second tray assembly (231b) is moved to the freezing position, it can be moved in the forward direction toward the water supply position.

[0351] Fig. 34 is a front view of an ice making assembly according to the first embodiment. Fig. 35 is a cross-sectional view taken along line 35-35 of Fig. 3 (b).

[0352] Referring to FIGS. 33 to 35, the bottom (422a) of the storage unit (422) may be positioned lower than the top (382b) of the first pusher (380). The bottom (422a) of the storage unit (422) may be positioned higher than the bottom (382a) of the first pusher (380) or the bottom of the first column (382).

[0353] The first frame (410) may further include a pusher receiving portion (422b) in which at least a portion of the first pusher (380) is positioned. At least a portion of the first pusher (380) may be received in the pusher receiving portion (422b) at the water supply position or ice-making position of the second tray assembly (231b).

[0354] In a state where the water tank (210) is accommodated in the receiving portion (411), the bottom (422a) of the storage portion (422) may be positioned lower than the discharge hole (217) of the water tank (210). A part of the water supply guide (220) may be positioned higher than the bottom (422a) of the storage portion (422).

[0355] The bottom (422a) of the storage unit (422) can overlap with the driving unit (290) in the vertical direction.

[0356] Some of the plurality of cold air holes (419) formed in the first frame (410) may be positioned higher than the first wall (241) of the bracket (240). Cold air passing through the cold air holes (419) may flow to the upper portion of the first tray (250).

[0357] Some of the plurality of cold air holes (419) can face the first pusher (380). Some of the plurality of cold air holes (419) can face the space between two adjacent first columns (382).

[0358] Some of the above plurality of cold air holes (419) may be positioned higher than the lower end (382a) of the first pusher (380).

[0359] Some of the above plurality of cold air holes (419) can face the space between the water supply guide (220) and the first wall (241).

[0360] Some of the above plurality of cold air holes (419) may be positioned higher than the bottom (422a) of the storage unit (422).

[0361] Some of the plurality of cold air holes (419) may be positioned lower than the bottom (422a) of the storage unit (422). The bottom (422a) of the storage unit (422) may guide the introduced cold air.

[0362] Meanwhile, with the freezer door (25) closed, the freezer (12) can be positioned on the left side of the ice making assembly based on Fig. 33.

[0363] The above storage unit (422) may be located closer to the freezer (12) than the first pusher (380).

[0364] In the ice-making position of the second tray assembly (231b), the second pusher (380) may be positioned closer to the freezer (12) than the ice-making cell (230a).

[0365] According to this embodiment, water can be manually supplied to the ice maker by removing the water tank, so there is no need for a valve or the like, and there is an advantage in that the water tank can be removed and washed.

[0366] According to this embodiment, since the water tank can be exposed to the outside of the ice making assembly while being accommodated in the receiving portion, there is an advantage in that the user can easily mount or detach the water tank.

[0367] In the present embodiment, the water tank can store water that can be used for one ice making operation of the ice maker, so that contamination of the water due to water remaining in the water tank for a long period of time can be reduced.

[0368] According to this embodiment, since the user can be restricted from removing the water tank while water is being supplied and ice making is being performed, redundant water supply due to re-installation of the water tank after removing the water tank can be prevented.

[0369] Fig. 36 is a drawing showing the structure of an ice maker according to the second embodiment.

[0370] This embodiment is otherwise identical to the first embodiment, except that some of the configurations of the first tray and bracket are different. Therefore, only the characteristic parts of this embodiment will be described below.

[0371] Referring to FIG. 36, in the present embodiment, the first tray (250) may further include an auxiliary storage compartment (254a). Water or cold air may pass through the auxiliary storage compartment (254a). The auxiliary storage compartment (254a) may be located above the ice-making cell (230a). The first tray (250) may further include an extension wall (254). The extension wall (254) may form the auxiliary storage compartment (254a).

[0372] The above water supply guide (220) may be mounted on the extension wall (254) or positioned close to the extension wall (254).

[0373] The above extension wall (254) may include a recessed portion (254b) that recesses downward from the upper end of the extension wall (254). The recessed portion (254b) may allow water overflowing from the ice-making cell (230a) to be discharged.

[0374] The first frame (410) may include a discharge path (411d). The discharge path (411d) may be aligned with the recessed portion (254b).

[0375] The bottom (441e) of the above discharge path (411d) may be positioned lower than the first wall (241) of the above bracket (240). The bottom (441e) of the above discharge path (411d) may be positioned lower than the upper end of the above extension (254).

[0376] Even if water overflows from the ice-making cell (230a), the overflowing water does not stagnate around the first tray (250) due to the above-mentioned recessed portion (254b) and the above-mentioned discharge path (411d), but can fall to the ice bin (480).

[0377] If the overflowing water stagnates around the first tray (250), there is a disadvantage in that the ice shape is not formed in a shape corresponding to the ice making cell (230a) due to the freezing of the ice in the ice making cell (230a) and the water existing on the outside of the first tray (250), and there is a concern that the ice-making performance may deteriorate during the ice-making process. However, according to the present embodiment, this problem can be solved.

[0378] Fig. 37 is a perspective view of an ice-making assembly according to a third embodiment, and Fig. 38 is a perspective view of a water tank according to the third embodiment. Fig. 39 is a perspective view of a first frame according to the third embodiment, and Fig. 40 is a drawing showing a state in which a restriction part is separated from the first frame according to the third embodiment.

[0379] Figure 41 (a) is a perspective view of a restriction according to the third embodiment viewed from one side, and Figure 41 (b) is a perspective view of a restriction according to the third embodiment viewed from the other side.

[0380] This embodiment is identical to the first embodiment in other respects, except for differences in the shape of the restriction portion and the shape of the water tank. Below, the characteristic parts of this embodiment will be described, and the same drawing reference numerals as in the first embodiment will be used for the same components.

[0381] Referring to FIGS. 37 to 41, in the present embodiment, the restriction member (350A) may move up and down and come into contact with the handle (213) of the water tank (210A) to restrict separation of the water tank (210A).

[0382] That is, the limiting part and the second operating part of the first embodiment can function as one limiting part (350A) in the present embodiment.

[0383] The above-described limiting member (350A) may include a first member (351). The first member (351) may be in contact with the first operating member (340) described in the first embodiment. The first member (351) may penetrate the movement guide (458) of the second frame (450).

[0384] The above-described limiting portion (350A) may further include a second member (352a). The second member (352a) may be stepped from the first member (351) in the X-axis direction. The second member (352a) may include a first portion (352a1) that is stepped from the first member (351) and a second portion (352a2) that is stepped from the first portion (352a1). The first portion (352a1) and the second portion (352a2) may also be stepped in the X-axis direction.

[0385] The second member (352a) may include a first contact end (352a3) for contacting the handle (213). The first contact end (352a3) may be provided on the upper side of the second part (352a2).

[0386] The first frame (410) may further include a space (511) formed on one side of the receiving portion (411). The space (511) may provide a space in which the limiting portion (350A) can be positioned.

[0387] The first frame (410) may further include a guide portion (512) that guides the up and down movement of the second portion (352a2). The guide portion (512) may be positioned in the space portion (511).

[0388] FIG. 42 (a) is a drawing showing the positional relationship between the restriction and the water tank at the first position of the restriction according to the third embodiment, and FIG. 42 (b) is a drawing showing the restriction and the first operating part at the first position of the restriction according to the third embodiment. FIG. 43 (a) is a drawing showing the positional relationship between the restriction and the water tank at the second position of the restriction according to the third embodiment, and FIG. 43 (b) is a drawing showing the restriction and the first operating part at the second position of the restriction according to the third embodiment. FIG. 44 is a drawing showing a state in which the first contact end of the restriction according to the third embodiment is in contact with the second contact end of the handle.

[0389] Referring to FIGS. 42 to 44, at the water supply position of the second tray assembly (231b), the restriction portion (350A) can be positioned at the first position. As long as no external force is applied to the restriction portion (350A), the restriction portion (350A) can pressurize the second portion (342b) of the first operating portion (340) by its own weight.

[0390] At the first position of the above-mentioned limiting portion (350A), the first contact end (352a3) of the above-mentioned limiting portion (350A) can be spaced apart from the second contact end (213b) provided at the end of the above-mentioned handle (213). Accordingly, a space can be formed between the above-mentioned limiting portion (350A) and the above-mentioned handle (213). In this state, the user can separate the water tank (210) by inserting a finger into the above-mentioned space and holding the above-mentioned handle (213).

[0391] At the first position of the above-mentioned restriction portion (350A) and the water supply position of the above-mentioned second tray assembly (231b), the contact portion (332) of the above-mentioned operating arm (330) can be in contact with or separated from the above-mentioned first operating portion (340).

[0392] Once the water supply is complete, the second tray assembly (231b) can be moved to the ice-making position.

[0393] In the process of the second tray assembly (231b) moving to the ice-making position, the operating arm (330) can move. As the operating arm (330) moves in the forward direction, the contact portion (332) of the operating arm (330) can press the first operating portion (340). For example, the contact portion (332) can press the first part (341a) of the first operating portion (340) downward. Then, the first operating portion (340) can rotate, and the second part (341b) of the first operating portion (340) can rise.

[0394] When the second part (341b) is raised, the restriction part (350A) can be raised. Then, the restriction part (350A) can be moved from the first position to the second position. When the restriction part (350A) is moved to the second position, the first contact end (352a3) of the restriction part (350A) can be brought into contact with the second contact end (213b) of the handle (213). For example, in a state where the first contact end (352a3) is brought into contact with the second contact end (213b), the first contact end (352a3) and the second contact end (213b) can overlap in the X-axis direction.

[0395] As another example, it is also possible for the first contact end (352a3) to protrude from the limiting portion (350A) and be inserted into a groove formed in the handle (213). Alternatively, it is also possible for the second contact end (213b) to protrude from the handle (213) and be inserted into a groove formed in the limiting portion (350A).

[0396] In the second position of the above-mentioned restriction portion (350A), the above-mentioned restriction portion (350A) may include a portion (352a4) that protrudes outward from the end of the handle (213). By the above-mentioned protruding portion (352a4), the user's access to the second contact end (213b) of the handle (213) may be restricted.

[0397] FIG. 45 is a plan view showing a portion of an ice maker equipped with a water supply guide according to the fourth embodiment.

[0398] This embodiment is otherwise identical to the first embodiment, except for the shape of the water supply guide. Therefore, only the distinctive features of this embodiment will be described below.

[0399] Referring to FIG. 45, the water supply guide (220A) of the present embodiment may include a bottom wall. The bottom wall may include a first portion (2211).

[0400] In this embodiment, the shape and position of the first part (2211) may be the same as the first part (221a) of the first embodiment.

[0401] The above-described bottom wall may further include a second portion (2212) extending from the first portion (2211). The second portion (2212) may extend from the first portion (2211) toward the ice-making cell (230a). Unlike the first embodiment, the water supply guide (220A) may guide water directly to the ice-making cell (230a) without bypassing the first pusher (380).

[0402] According to this embodiment, there is an advantage in that the structure of the water supply guide (220A) is simplified.

[0403] FIG. 46 is a perspective view of an ice making assembly according to a fifth embodiment, FIG. 47 is a perspective view of an ice making assembly with the first frame removed according to the fifth embodiment, and FIG. 48 is a drawing showing a cold air guide according to the fifth embodiment.

[0404] The basic structure of the ice-making assembly of this embodiment is identical to that of the first embodiment, with the only difference being that the ice-making assembly is mounted on the refrigerator door. Therefore, only the distinctive features of this embodiment will be described below.

[0405] Referring to FIGS. 46 to 48, the ice-making assembly (200B) of the present embodiment can be mounted on a refrigerator door (20). Although not shown, the refrigerator door (20) can include an insulated space that is insulated from the refrigerator (11), and the ice-making assembly (200B) can be accommodated in the insulated space.

[0406] The above-mentioned insulation space can be supplied with cold air from the above-mentioned freezer (12) or air that has been heat-exchanged with the evaporator for cooling the above-mentioned freezer (12).

[0407] The above ice-making assembly (200B) may include a cold air hole (4101) through which cold air is introduced. The cold air hole (4101) may be formed, for example, on a side of the first frame (410).

[0408] The above ice making assembly (200B) may further include a cold air guide (510) that guides cold air introduced through the cold air hole (4101).

[0409] The above cold guide (510) may be installed, for example, on the bracket (240). The cold guide (510) may be positioned on the upper side of the first wall (241) of the bracket (240).

[0410] The above cold air guide (510) may include a cold air inlet (512). The cold air inlet (512) may be aligned with the cold air hole (4101).

[0411] The above cold air guide (510) may further include a cold air outlet (514). The cold air guide (510) may include, for example, a portion extending in the X-axis direction. The cold air outlet (514) may allow cold air to be discharged in a direction intersecting the X-axis direction.

[0412] The above cold air guide (510) may be provided with a guide rib (515) for changing the direction of cold air flow. Cold air whose flow direction has been changed by the guide rib (515) may be discharged through the cold air outlet (514) and flow toward the ice-making cell (230a).

[0413] According to this embodiment, ice can be created even when the ice-making assembly is mounted on the refrigerator door, and the supplied cold air can flow smoothly toward the ice-making cell (230a) by the cold air guide.

[0414] Meanwhile, in the above embodiments, the ice-making assembly is described as being installed on a door, but it should be noted that the configuration of the limiting part, actuator, detector, etc. for limiting separation of the water tank can be applied equally even when the ice-making assembly is installed in a storage room.
