[0090] The ice tray (130) can rotate around the first rotation axis (131a, 131b) and the second rotation axis (132a, 132b) through the rotational force applied through the tray rotation part (131c, 132c). The tray rotation part (131c, 132c) can stably rotate the ice tray (130) by receiving a uniform force from the rotation lever (140) described later.

[0091] The rotary lever (140) may include a lever handle (141), a lever coupling portion (142) protruding rearward from the lever handle (141), and a link structure (143) coupled to the lever coupling portion (142) and connecting the lever handle (141) and the ice tray (130).

[0092] The lever handle (141) can be coupled to the lever mounting portion (112). The lever handle (141) can include a lever shaft (141a) provided on both sides. The lever handle (141) can rotate around the lever shaft (141a). The lever shaft (141a) can be coupled to the lever shaft coupling portion (112a) of the lever mounting portion (112).

[0093] The lever coupling portion (142) may be formed to protrude downwardly from the rear of the lever handle (141). The lever coupling portion (142) may have a rounded shape toward the lower rear. A link structure (143) may be rotatably coupled to the end of the lever coupling portion (142).

[0094] The link structure (143) can connect the lever coupling portion (142) and the ice tray (130). The link structure (143) can transmit the rotational force of the lever handle (141) to the ice tray (130), thereby rotating the ice tray (130). Accordingly, the ice formed on the ice tray (130) can fall toward the ice bucket (160).

[0095] The rotational motion of the ice tray (130) via the rotation lever (140) will be described later.

[0096] A water tank (150) may be mounted on the tank mounting portion (111) of the first main body (110). The water tank (150) may store water supplied to the ice tray (130). The ice maker (100) according to one embodiment may be a manual ice maker (100) in which a user manually supplies water. The water tank (150) may be filled with an amount of water sufficient to make ice at one time using the ice maker (100).

[0097] The water tank (150) may include a tank body (151), a partition member (152) provided inside the tank body (151), and a cover member (154) covering an opening (153) of the tank body (151).

[0098] The tank body (151) may include a water reservoir (151a, 151b) that accommodates water therein. The tank body (151) may include an opening (153) that is open on one side. The water reservoir (151a, 151b) may be exposed to the outside through the opening (153).

[0099] A tank grip portion (151c) may be formed on the opposite side of the opening (153) in the tank body (151). A user can easily separate the water tank (150) from the first main body (151) through the tank grip portion (151c).

[0100] The water reservoirs (151a, 151b) may be partitioned by a partition member (152). For example, the water reservoirs (151a, 151b) may include a first water reservoir (151a) located on one side of the partition member (152) and a second water reservoir (151b) located on the other side. The first water reservoir (151a) may receive water supplied to the first tray (131), and the second water reservoir (151b) may receive water supplied to the second tray (132). A water level boundary line (not shown) may be formed on the inner surface of the tank body (151) or one surface of the partition member (152) to guide the user to an appropriate amount of water to be supplied.

[0101] The opening (153) of the tank body (151) can be covered by a cover member (154). After pouring water into the reservoir (151a, 151b), the user can cover the opening (153) using the cover member (154). The cover member (154) can be easily detached from the tank body (151). For example, the cover member (154) can be fitted into the opening (153).

[0102] A first water supply hole (154a) corresponding to the first reservoir (151a) and a second water supply hole (154b) corresponding to the second reservoir (151b) may be formed in the cover member (154). That is, water contained in the first reservoir (151a) may be supplied to the first tray (131) through the first water supply hole (154a), and water contained in the second reservoir (151b) may be supplied to the second tray (132) through the second water supply hole (154b).

[0103] A water supply guide (180) described later may be combined with the second water supply hole (154b). In one embodiment, the water tank (150) may be located above the first tray portion (131). As described above, the water tank (150) may accommodate water to be supplied to the first tray portion (131) and the second tray portion (132). Therefore, the water tank (150) located above the first tray portion (131) may be provided with a water supply guide (180) to supply water to the second tray portion (132). That is, water accommodated in the second water reservoir (151b) may move through the second water supply hole (154b) and the water supply guide (180) and be supplied to the second tray portion (132).

[0104] An ice bucket (160) can be accommodated in the first body receiving portion (113) of the first main body (110). The ice bucket (160) can include an ice storage portion (160a) for storing ice dropped from an ice tray (130). The ice bucket (160) can be configured to be pulled out and inserted from an ice maker (100). For example, the ice bucket (160) can further include a bucket guide portion (161) configured to be pulled out and inserted along a first guide portion (114) and a second guide portion (125).

[0105] An ice maker (100) according to one embodiment may further include a coupling member (170) coupled to one side of a second main body (120). The first storage member (34) may be coupled to one side of the ice maker (100) through the coupling member (170). The coupling member (170) may include an ice maker coupling portion (171) coupled to one side of the second main body (120) and a coupling portion (172) protruding from one side of the ice maker coupling portion (171).

[0106] In another embodiment, if the left-right width of the ice maker (100) is formed to correspond to the left-right width of the door body (31), the connecting member (170) may be omitted. In this case, both sides of the ice maker (100) may be directly connected to the door body (31). For example, the main body connecting portion (126) formed on both sides of the second main body (120) may be connected to the second door connecting portion (332) of the door body (31).

[0107] An ice maker (100) according to one embodiment may further include a water supply guide (180) for supplying water stored in the tank body (151) to the second tray (132).

[0108] The water supply guide (180) may include a rod-shaped guide body (181) and a water supply guide hole (182) formed at one end of the guide body (181).

[0109] The guide body (181) may have a shape extending in the width direction of the freezer door (30). One end of the guide body (181) may be located on the upper side of the first tray part (131), and the other end may be located on the upper side of the second tray part (132).

[0110] A water supply hole (111b) through which water is supplied from a water tank (150) may be located on the upper side of one end portion located on the upper side of the first tray portion (131) of the guide body (181). A water supply guide hole (182) may be formed on the other end portion located on the upper side of the second tray portion (132) of the guide body (181).

[0111] Through the above structure, when water is supplied from the water tank (150) to the one end of the guide body (181) through the water supply hole (111b), it can move along the length direction of the guide body (181) and move toward the second tray part (132) through the water supply guide hole (181) formed at the other end. Therefore, in an ice maker (100) equipped with a single water tank (150), water can be stably supplied to a plurality of tray parts (131, 132).

[0112] Figures 10 and 11 are partial perspective views showing the coupling relationship between the rotary lever and the ice tray.

[0113] Referring to FIGS. 10 and 11, the rotary lever (140) is formed at an end of the link structure (143) and may further include a link coupling portion (144) coupled with the ice tray (130). The link coupling portion (144) may have a shape extending from the end of the link structure (143) to both sides. For example, the link coupling portion (144) may have a shape extending toward the first tray portion (131) and the second tray portion (132).

[0114] A first tray rotation part (131c) may be coupled to one end of the link coupling part (144), and a second tray rotation part (132c) may be coupled to the other end. For example, the link coupling part (144) may include a link coupling hole (144a) into which the first tray rotation part (131c) and the second tray rotation part (132c) are each inserted.

[0115] The link coupling portion (144) may have a left-right symmetrical structure based on the link structure (143). Therefore, when the user rotates the lever handle (141) to rotate the link structure (143), a rotational force of a uniform magnitude may be applied to the first tray portion (131) and the second tray portion (132).

[0116] A water supply guide (180) may be positioned between the lever mounting portion (112) and the second tray coupling portion (117). Accordingly, in an ice maker (100) equipped with a single water tank (150), water can be stably supplied to multiple tray portions (131, 132). In addition, a path for the water supply guide (180) to pass through can be secured between the lever mounting portion (112) and the second tray coupling portion (117), thereby forming a more compact ice maker (100) structure.

[0117] Figures 12 and 13 are schematic diagrams showing the rotation process of an ice tray in an ice maker according to one embodiment.

[0118] Referring to FIGS. 12 and 13 along with FIGS. 10 and 11, a user can rotate the lever handle (141). When the lever handle (141) rotates, the position of the link structure (143) coupled to the tray rotation part (131c, 132c) of the lever coupling part (142) can be changed upward. That is, when the lever handle (141) rotates, a rotational force can be applied to the ice tray (130) through the link structure (143).

[0119] The link coupling portion (144) located at the end of the link structure (143) can be coupled to the first tray rotation portion (131c) and the second tray rotation portion (132c), respectively. Therefore, the rotational force applied to the ice tray (130) through the rotation of the lever handle (141) can be uniformly applied to the first tray portion (131) and the second tray portion (132), respectively. Therefore, the first tray portion (131) and the second tray portion (132) can be stably rotated through the rotation of a single lever handle (141).

[0120] According to one embodiment of the refrigerator (1), an ice maker (100) having a slim and compact shape and provided in a freezer door (30) can be included to minimize the reduction in storage space in the freezer (12).

[0121] According to a refrigerator (1) according to one embodiment, a water supply guide (180) that guides water from a water tank (150) to an ice tray (130) is provided so that water can be stably supplied to a plurality of tray sections (131, 132) arranged in the width direction of the freezer door (30).

[0122] According to a refrigerator (1) according to one embodiment, a plurality of tray parts (131, 132) arranged in the width direction of a freezer door (30) can be stably rotated through a rotation link structure that includes a link connecting part extending in the arrangement direction of ice trays (130) and connecting a rotation lever (140) and ice trays (130).

[0123] Hereinafter, another embodiment of a refrigerator (1) and an ice maker (100) included therein will be described. In the following embodiments, descriptions of the same configurations as those in the previously described embodiments will be omitted or simplified, and the differences will be primarily described.

[0124] Fig. 14 is a partial perspective view of an ice maker according to another embodiment. Fig. 15 is an enlarged view of the portion where the rotary lever and the ice tray are connected in Fig. 14.

[0125] Referring to FIGS. 14 and 15, the ice maker (100') according to the present embodiment, unlike the ice maker (100) according to one embodiment, can transmit rotational force through gear coupling. The ice maker (100') according to the present embodiment may include a lever coupling portion (142'), a link structure (143'), and an inner rotation shaft (131b', 132b') that are gear-coupled to each other. Unlike the ice maker (100) according to one embodiment, the ice maker (100') according to the present embodiment may not have a separate tray rotation portion (131c, 132c).

[0126] The ice maker (100') according to the present embodiment may include a lever coupling portion (142') protruding rearward from a lever handle (141). The lever coupling portion (142') may have a bent shape and include a lever gear portion (142a') formed on the rear surface. The lever gear portion (142a') may be formed on both sides of the lever coupling portion (142') so as to correspond to the first tray portion (131) and the second tray portion (132), respectively.

[0127] The lever gear portion (142a') is gear-coupled with a link structure (143') described later and can transmit the rotational force of the lever handle (141) to the link structure (143'). That is, the link structure (143') can rotate through the rotation of the lever handle (141).

[0128] At the rear of the lever coupling portion (142'), a link structure (143') that is gear-coupled with the lever gear portions (142a') on both sides may be provided. Although not shown, the link structure (143') may be rotatably coupled to the first main body (110) or the second main body (120). The link structure (143') may be a rotational force transmission means that transmits rotational force through the rotation of the lever handle (141) to the ice tray (130).

[0129] In the ice maker (100) according to the present embodiment, the inner rotation shafts (131b', 132b') may have a gear shape. The inner rotation shafts (131b', 132b') may be gear-coupled with the link structure (143'). Therefore, when the link structure (143') rotates by rotating the lever handle (141), the inner rotation shafts (131b', 132b') gear-coupled therewith may rotate together. Through the above structure, the first tray portion (131) and the second tray portion (132) may rotate together through a uniform rotational force.

[0130] However, as another embodiment, the link structure (143') may be omitted and the lever gear portion (142a') of the lever coupling portion (142') may be directly gear-coupled to the inner rotation shaft (131b', 132b').

[0131] In the present embodiment, the water supply guide (180') may have a pipe shape, unlike the water supply guide (180) according to one embodiment. Since the inner rotation shafts (131b', 132b') in the ice maker (100) according to the present embodiment have a gear shape, the water supply guide (180') may have a pipe shape, thereby enabling more efficient use of space. In the present embodiment, one end of the water supply guide (180') may be coupled to the water supply hole (111b), and the other end may be located above the second tray part (132). Through the above structure, when water is supplied from the water tank (150) to the one end of the water supply guide (180') through the water supply hole (111b), the water may move along the water supply guide (180') and move toward the second tray part (132) through the other end. Therefore, in an ice maker (100) equipped with a single water tank (150), water can be stably supplied to multiple trays (131, 132).

[0132] Figures 16 and 17 are schematic diagrams illustrating the rotation process of an ice tray in an ice maker according to another embodiment. Figures 16 and 17 are diagrams illustrating the rotation process of an ice tray (100') according to the embodiment described above with reference to Figures 14 and 15.

[0133] Referring to FIGS. 16 and 17, a user can rotate the lever handle (141). When the lever handle (141) rotates, the lever coupling portion (142') can rotate the link structure (143') that is gear-coupled to the inner rotation shaft (131b', 132b'). That is, when the lever handle (141) rotates, a rotational force can be applied to the ice tray (130') through the link gear portions (142a') provided on both sides of the link coupling portion (142') and the link structure (143') that is gear-coupled to the link gear portions (142a').

[0134] Link gear parts (142a') are provided on both sides of the rear surface of the link coupling part (142'), and a link structure (143') can be gear-coupled to each link gear part (142a'). In addition, a first inner rotation axis (131b') of the first tray part (131) and a second inner rotation axis (132b') of the second tray part (132) can be gear-coupled to each link structure (143').

[0135] Through the above structure, the rotational force applied to the ice tray (130') through the rotation of the lever handle (141) can be uniformly applied to the first tray section (131) and the second tray section (132), respectively. Therefore, the first tray section (131) and the second tray section (132) can be stably rotated through the rotation of a single lever handle (141).

[0136] Fig. 18 is a perspective view of an ice maker according to another embodiment.

[0137] Referring to FIG. 18, the ice maker (100'') according to the present embodiment may include a plurality of water tanks (150). The number of water tanks (150) may correspond to the number of tray sections (131, 132) included in the ice tray (130). For example, the ice maker (100'') according to the present embodiment may include a water tank (150) for storing water supplied to a first tray section (131) and a water tank (150) for storing water supplied to a second tray section (132).

[0138] Accordingly, the first main body (110'') may include a plurality of tank mounting portions (111) on which each water tank (150) is mounted. For example, the plurality of tank mounting portions (111) may be positioned on the upper portion of the first tray portion (131) and the upper portion of the second tray portion (132), respectively.

[0139] According to the present embodiment, a separate water tank (150) is provided for each tray section (131, 132) included in the ice tray (130), so that the amount of ice made can be freely adjusted. In addition, each water tank (150) is placed on the upper portion of each tray section (131, 132) of the ice tray (130), so that residual water can be prevented from being generated in the water tank (150).

[0140] Fig. 19 is a perspective view of an ice maker according to another embodiment.

[0141] Referring to FIG. 19, the ice maker (100''') according to the present embodiment is different from the ice maker (100) according to one embodiment in that it includes a first main body (110''') in which the positions of the tank mounting portion (111''') on which the water tank (150) is mounted and the lever mounting portion (112''') on which the rotary lever (140) is mounted are changed. The ice maker (100''') according to the present embodiment has the advantage that the position of the tank mounting portion (111''') on which the water tank (150) is mounted and the position of the lever mounting portion (112''') on which the rotary lever (140) is mounted can be freely set.

[0142] Fig. 20 is a perspective view of an ice maker according to another embodiment.

[0143] Referring to FIG. 20, the ice maker (100'''') according to the present embodiment is formed on the first main body (110''''), and is different from the ice maker (100) according to one embodiment in that the location of the tank mounting portion (111'''') on which the water tank (150) is mounted is located on the opposite side. The ice maker (100'''') according to the present embodiment has the advantage of being able to freely set the location of the tank mounting portion (111'''') on which the water tank (150) is mounted.

[0144] FIG. 21 is a partial perspective view of an ice maker according to another embodiment.

[0145] Referring to FIG. 21, this embodiment differs from the ice maker (100) according to one embodiment in that it includes a water supply guide (180'') of a different shape.

[0146] In the present embodiment, the water supply guide (180'') may have a pipe shape, unlike the water supply guide (180) according to one embodiment. Since the water supply guide (180'') has a pipe shape, more efficient space utilization is possible. In the present embodiment, one end of the water supply guide (180'') may be coupled to the water supply hole (111b), and the other end may be located above the second tray part (132). Through the above structure, when water is supplied from the water tank (150) to the one end of the water supply guide (180'') through the water supply hole (111b), it may move along the water supply guide (180'') and move toward the second tray part (132) through the other end. Therefore, in an ice maker (100) equipped with a single water tank (150), water can be stably supplied to a plurality of tray parts (131, 132).

[0147] Fig. 22 is a front view of a refrigerator according to another embodiment.

[0148] Referring to FIG. 22, a refrigerator (1') according to the present embodiment may include a cabinet (10') and a door (20', 30') connected to the cabinet (10') to open and close a refrigerator compartment and a freezer compartment (11').

[0149] In this embodiment, a refrigerator (1') having a structure in which a freezer (11') is positioned at the top and a refrigerator (11') is positioned at the bottom is described as an example, but this embodiment is not limited to the shape of the refrigerator (1').

[0150] In this embodiment, the door (20', 30') may include a freezer door (30') for opening and closing the freezer (11') and a refrigerator door (20') for opening and closing the refrigerator.

[0151] In the present embodiment, the freezer door (30') may include a door body (31') and an ice maker (100) coupled to the rear of the door body (31'). The refrigerator (1') according to the present embodiment is different from the refrigerator (1) according to one embodiment in that the first storage member (34) is omitted, and one end and the other end of the ice maker (100) are directly coupled to the door body (31'). The left-right width of the ice maker (100) may correspond to the left-right width of the door body (31'). That is, the ice maker (100) may have a size and shape corresponding to the door body (31') and may be directly coupled to the door body (31').

[0152] According to the refrigerator (1') according to the present embodiment, there is an advantage in that the ice maker (100) can be freely combined according to the shape of the freezer door (30').

[0153] According to a refrigerator according to an embodiment of the present invention, an ice maker is provided on the door side and has a slim and compact shape, thereby minimizing the reduction in freezer storage space, and thus its industrial applicability is recognized.

[0154] According to a refrigerator according to an embodiment of the present invention, a water supply pipe is provided to guide water from a water tank to an ice tray, thereby stably supplying water to a plurality of ice trays arranged in the width direction of the door, and thus, industrial applicability is recognized.

[0155] According to a refrigerator according to an embodiment of the present invention, a plurality of ice trays arranged in the width direction of the door can be stably rotated through a rotation link structure that connects a rotation lever and an ice tray, including a link connecting portion extending in the direction of arrangement of ice trays, and thus, industrial applicability is recognized.
