FIG. 1 is a perspective view of a refrigerator according to one or more embodiments of the present disclosure. FIG. 2 is a schematic lateral cross-sectional view of the refrigerator according to one or more embodiments of the present disclosure.

Referring to FIGS. 1 and 2, a refrigerator 1 may include a body 10, a storage compartment 20 provided inside the body 10, a door 30 configured to open and close the storage compartment 20, and a cooling system configured to supply cold air to the storage compartment 20.

The body 10 may have a front side formed to be open to allow a user to put food in the storage compartment 20 or take food out of the storage compartment 20. That is, the body 10 may include an opening 10a formed in the front side of the body 10. The opening 10a of the body 10 may be opened and closed by the door 30. The opening 10a of the body 10 may be referred to as an opening 10a of an outer case 12, an opening 10a of an inner case 11, or the like, which will be described below.

The body 10 may include the inner case 11 configured to form the storage compartment 20, the outer case 12 configured to form an exterior of the refrigerator 1, and a body insulator 13 provided between the inner case 11 and the outer case 12.

The outer case 12 may be formed to have a substantially box-like shape having an open front side. The outer case 12 may form upper and lower surfaces, left and right side surfaces, and a rear surface of the refrigerator 1.

The outer case 12 may be configured to include a metal material. For example, the outer case 12 may be manufactured by processing a steel sheet material.

The inner case 11 may have an open front side. The inner case 11 may have the storage compartment 20 provided therein and may be provided inside the outer case 12. An inner wall of the inner case 11 may form an inner wall of the storage compartment 20.

The inner wall of the inner case 11 may include a first inner wall 11a, a second inner wall 11b opposing the first inner wall 11a, a rear wall 11c provided between the first inner wall 11a and the second inner wall 11b, an upper wall, and a lower wall. For example, the first inner wall 11a may refer to the inner wall of the inner case 11 that is provided at the right side when the refrigerator 1 is viewed from the front. The second inner wall 11b may refer to the inner wall of the inner case 11 that opposes the first inner wall 11a and is provided at the left side when the refrigerator 1 is viewed from the front.

However, the positions of the first inner wall 11a and the second inner wall 11b are not limited thereto, and conversely, the inner wall of the inner case 11 that is provided at the left side when the refrigerator 1 is viewed from the front may be referred to as the first inner wall, and the inner wall of the inner case 11 that is provided at the right side when the refrigerator 1 is viewed from the front may be referred to as the second inner wall.

The inner case 11 may be configured to include a plastic material. For example, the inner case 11 may be manufactured by a vacuum forming process. For example, the inner case 11 may be manufactured by an injection molding process.

The body insulator 13 may be provided so that the outer case 12 and the inner case 11 are insulated from each other. The body insulator 13 may couple the inner case 11 and the outer case 12 to each other by being foamed between the inner case 11 and the outer case 12. The body insulator 13 may prevent a heat exchange from occurring between the inside of the storage compartment 20 and the outside of the body 10 to improve efficiency of cooling the inside of the storage compartment 20.

Urethane foam insulation, expanded polystyrene insulation (EPS), a vacuum insulation panel, and the like may be used as the body insulator 13. However, the present disclosure is not limited thereto, and the body insulator 13 may be configured to include various other materials.

The storage compartment 20 may be formed inside the body 10. For example, the storage compartment 20 may include a freezer compartment maintained at a temperature of about −30 to 0° C. to freeze and store food.

A shelf 16 on which food may be placed, a movable shelf 17 which may be inserted into and withdrawn from the inner case 11 and on which food may be placed, and a drawer 18 which may be inserted into and withdrawn from the inner case 11 and in which food may be stored may be provided in the storage compartment 20.

The inner case 11 may include an inclined wall 11f. The inclined wall 11f may be disposed at a front of the body 10 in order to be adjacent to the door 30. The inclined wall 11f may be, from one side adjacent to the door 30 toward the other side facing the rear wall 11c, inclined toward the inside of the storage compartment 20 in a left-right direction. The other side of the inclined wall 11f may be a portion where the inclined wall 11f meets the first inner wall 11a or the second inner wall 11b. The inclined wall 11f may be disposed along at least a portion of the opening 10a.

An inclined protruding wall 11g may be disposed under the inclined wall 11f. The inclined protruding wall 11g may be formed to protrude further toward the inside of the storage compartment 20 in the left-right direction than the inclined wall 11f. Also, the inclined protruding wall 11g may be formed to protrude further toward the front than the inclined wall 11f. The inclined protruding wall 11g may include a protruding upper surface 11ga. The protruding upper surface 11ga may be disposed adjacent to a front inclined portion 1130. The inclined protruding wall 11g may be disposed along at least a portion of the opening 10a.

When a user views the inside of the storage compartment 20 through the opening 10a of the body 10, the inclined wall 11f and the inclined protruding wall 11g may provide an improved aesthetic sense that makes the volume of the storage compartment 20 look wider to the user.

An ice maker cover 1100 of an ice maker 1000 may have the front inclined portion 1130 (see FIG. 5) formed to correspond to the inclined shape of the inclined protruding wall 11g. Since the front inclined portion 1130 is inclined upward toward the rear, the inclined shape of the front inclined portion 1130 may form a harmonious aesthetic sense with the inclined protruding wall 11g. The ice maker cover 1100 will be described below.

The refrigerator 1 may include a cooling system provided to generate cold air using a cooling cycle and supply the generated cold air to the storage compartment 20.

The cooling system may generate cold air using evaporative latent heat of a refrigerant in the cooling cycle. The cooling system may be configured to include a compressor 73, a condenser, an expansion valve, an evaporator 71, a blower fan 72, and the like.

A cooling chamber 50 and a mechanical chamber 60 that allow the cooling system to be disposed may be provided in the body 10. For example, configurations such as the evaporator 71 configured to generate cold air and the blower fan 72 provided to allow the cold air generated by the evaporator 71 to flow may be provided in the cooling chamber 50. Configurations such as the compressor 73 and the condenser may be provided in the mechanical chamber 60.

The cooling chamber 50 may be disposed behind the storage compartment 20. The mechanical chamber 60 may be disposed behind the storage compartment 20.

Components of the refrigerator 1 that constitute the cooling system may have a relatively large weight. Accordingly, the cooling chamber 50 and the mechanical chamber 60 may be provided at a lower portion of the body 10. However, the present disclosure is not limited thereto, and the cooling chamber 50 and the mechanical chamber 60 may be disposed in various other ways, and the components constituting the cooling system may be disposed in various ways to correspond to the positions of the cooling chamber 50 and the mechanical chamber 60.

Since cold air is generated by the evaporator 71 in the cooling chamber 50, the cooling chamber 50 may maintain a relatively low-temperature state. On the other hand, since heat is generated by the compressor 73, the condenser, and the like in the mechanical chamber 60, the mechanical chamber 60 may maintain a relatively high-temperature state. Accordingly, the cooling chamber 50 and the mechanical chamber 60 may be formed in separate spaces and insulated from each other. For example, the body insulator 13 may be foamed between the cooling chamber 50 and the mechanical chamber 60.

As illustrated in FIG. 2, the evaporator 71 provided in the cooling chamber 50 may evaporate a refrigerant to generate cold air, and the cold air generated by the evaporator 71 may flow due to the blower fan 72. The cold air flowing due to the blower fan 72 may flow from the cooling chamber 50 to the storage compartment 20. The cooling chamber 50 may be provided to communicate with the storage compartment 20.

For example, cold air generated by the evaporator 71 may flow toward a top of the cooling chamber 50 due to the blower fan 72. The cold air flowing due to the blower fan 72 may flow toward a top of the body 10 along a cold air supply duct 14. The cold air may be discharged forward from the cold air supply duct 14 and eventually be introduced into the storage compartment 20. On the other hand, for example, cold air generated by the evaporator 71 may flow to a lower portion of the body 10 due to the blower fan 72 and be introduced into the storage compartment 20.

In other words, as illustrated in FIG. 2, the refrigerator 1 according to one or more embodiments of the present disclosure may be an indirect-cooling refrigerator. Hereinafter, for convenience of description, description will be given assuming that the refrigerator 1 according to one or more embodiments of the present disclosure is an indirect-cooling refrigerator, but the spirit of the present disclosure is not limited thereto and may also apply to a direct-cooling refrigerator.

The evaporator 71, the blower fan 72, and the like disposed in the cooling chamber 50 may be referred to as cold air supply devices in that the evaporator 71 generates cold air and the blower fan 72 supplies the cold air to the storage compartment 20.

The body 10 may include the cold air supply duct 14. The cold air supply duct 14 may form a cold air flow path along which cold air generated by the cold air supply device flows from the cooling chamber 50 to the storage compartment 20. The storage compartment 20 may be provided to communicate with the cold air supply duct 14.

The cold air supply duct 14 may be formed inside the inner case 11. The cold air supply duct 14 may be formed at a rear portion of the inner case 11. More specifically, the cold air supply duct 14 may be provided behind the storage compartment 20.

An outer surface of the door 30 may form a portion of the exterior of the refrigerator 1. While the door 30 is at a closing position, the outer surface of the door 30 may form a front surface of the door 30.

An inner surface of the door 30 may be formed at a side opposite to the outer surface of the door 30. While the door 30 is at the closing position, the inner surface of the door 30 may form a rear surface of the door 30. While the door 30 is at the closing position, the inner surface of the door 30 may be provided to face the inside of the body 10. While the door 30 is at the closing position, the inner surface of the door 30 may be provided to cover the front of the storage compartment 20.

A foaming space may be formed between the outer surface of the door 30 and the inner surface of the door 30, and a door insulator 31 may be foamed in the foaming space. The door insulator 31 may prevent a heat exchange from occurring between the outer surface and the inner surface of the door 30. The door insulator 31 may improve insulation performance between the inside of the storage compartment 20 and the outside of the door 30.

Urethane foam insulation, expanded polystyrene insulation (EPS), a vacuum insulation panel, and the like may be used as the door insulator 31. However, the present disclosure is not limited thereto, and the door insulator 31 may be configured to include various other materials.

For example, the door insulator 31 may be configured with an insulator made of the same material as the body insulator 13. On the other hand, for example, the door insulator 31 may be configured with an insulator made of a different material from the body insulator 13.

A door gasket 33 provided to seal a gap between the door 30 and the body 10 and prevent leakage of cold air from the storage compartment 20 may be provided on the inner surface of the door 30. The door gasket 33 may be provided along the periphery of the inner surface of the door 30.

The first ice maker case wall 1210a may be disposed to be substantially parallel to the first inner wall 11a. The second ice maker case wall 1210b may be disposed to be substantially parallel to the second inner wall 11b.

The first ice maker case wall 1210a and the second ice maker case wall 1210b may be formed parallel to each other. The first ice maker case wall 1210a and the second ice maker case wall 1210b may be formed to have shapes that substantially correspond to each other.

The inner case 11 may include the holders 11aa and 11bb formed on the inner walls 11a and 11b of the inner case 11. The ice maker case 1200 may be supported by the holders 11aa and 11bb.

The holders 11aa and 11bb may be formed to have various shapes that can support the ice maker case walls 1210a and 1210b.

For example, the holders 11aa and 11bb may be formed to have shapes that protrude from the inner walls 11a and 11b of the inner case 11. The holders 11aa and 11bb may be formed to protrude to support the ice maker case walls 1210a and 1210b. The holders 11aa and 11bb may be formed to protrude toward the inside of the storage compartment 20. In this case, as illustrated in FIGS. 3 to 6, the holders 11aa and 11bb may be inserted into concave portions formed in the ice maker case walls 1210a and 1210b and support the ice maker case walls 1210a and 1210b. Alternatively, the holders 11aa and 11bb may support lower sides of the ice maker case walls 1210a and 1210b.

For example, the holders 11aa and 11bb may be formed to have shapes that are concavely recessed in the inner walls 11a and 11b of the inner case 11. Unlike in FIGS. 3 to 6, portions protruding toward the inner walls 11a and 11b of the inner case 11 may be provided on the ice maker case walls 1210a and 1210b, and as the protruding portions of the ice maker case walls 1210a and 1210b are inserted into the holders 11aa and 11bb, the ice maker case walls 1210a and 1210b may be supported by the holders 11aa and 11bb.

Hereinafter, description will be given based on the embodiment in which the holders 11aa and 11bb are formed to protrude to support the ice maker case walls 1210a and 1210b as illustrated in FIGS. 3 to 6. However, the spirit of the present disclosure is not limited thereto, and, for example, as described above, the holders 11aa and 11bb supporting the ice maker case walls 1210a and 1210b may be formed to have shapes that are concavely recessed in the inner walls 11a and 11b of inner case 11.

The holders 11aa and 11bb may extend in a direction parallel to the forward-backward direction of the inner case 11. The holders 11aa and 11bb may extend in a direction parallel to the forward-backward direction of the inner walls 11a and 11b of the inner case 11. Accordingly, the ice maker case walls 1210a and 1210b may be stably supported in the up-down direction of the inner case 11 by the holders ilea and 11bb.

For example, the ice maker case 1200 may be mounted by sliding from a front of the inner case 11 toward a rear thereof along the holders 11aa and 11bb extending in the direction parallel to the forward-backward direction of the inner case 11. In other words, the ice maker case 1200 may be mounted in the inner case 11 by sliding from the front of the inner case 11 toward the rear thereof. When being mounted in the inner case 11, the ice maker case 1200 may be inserted from the front of the inner case 11 toward the rear thereof.

When the ice maker case 1200 is being mounted in the inner case 11, a mounting position in the inner case 11, a mounting direction in the inner case 11, and the like may be guided by the holders 11aa and 11bb.

However, the present disclosure is not limited thereto, and the ice maker case 1200 may be mounted in the inner case 11 in various other ways. For example, the ice maker case 1200 may be mounted by sliding in the up-down direction relative to the inner case 11. Even in this case, the holders 11aa and 11bb may still extend in the direction parallel to the forward-backward direction of the inner case 11.

The holders 11aa and 11bb may be provided to support upper portions of the ice maker case walls 1210a and 1210b.

By the above configuration, the first ice making tray 1310 may receive power from the first driving portion 1320 and may rotate about the axis of rotation in the horizontal direction of the refrigerator 1. According to rotation of the first ice making tray 1310, ice formed in the first ice making tray 1310 may be discharged from the first ice making cell 1311 and move to the first accommodating portion 110 of the ice bucket 100.

The first ice making unit 1300 may include an ice-full detection lever 1330. The ice-full detection lever 1330 may be provided to detect whether ice is full in the first accommodating portion 110 of the ice bucket 100 that is disposed under the ice maker 1000.

The ice-full detection lever 1330 may be coupled to the first driving portion 1320. Specifically, the ice-full detection lever 1330 may be coupled to a side portion of the first driving portion 1320. The ice-full detection lever 1330 may be coupled to be rotatable relative to the first driving portion 1320.

When it is determined by the ice-full detection lever 1330 that ice is full in the first accommodating portion 110, a controller controls to prevent any further water supply to the ice maker 1000. In this way, it is possible to prevent more ice than is necessary from being collected in the ice bucket 100.

The first ice making unit 1300 may further include a sensor module 1340. The sensor module 1340 may include a sensor, a case configured to accommodate the sensor, an insulator, and the like. The sensor module 1340 may be mounted under the first ice making tray 1310. The sensor of the sensor module 1340 may be a temperature sensor provided to detect temperature of the first ice making tray 1310.

When it is detected by the sensor module 1340 that the temperature of the first ice making tray 1310 is a predetermined temperature or lower, the controller may determine that ice formation is completed in the first ice making tray 1310. Based on the determination that ice formation is completed in the first ice making tray 1310, the controller may control driving of the first driving portion 1320 so that the first ice making tray 1310 rotates. In this way, ice formed in the first ice making tray 1310 may be collected in the first accommodating portion 110 of the ice bucket 100 that is disposed under the first ice making tray 1310.

The configuration relating to the first ice making unit 1300 described above with reference to FIG. 7 is only one example of an ice making unit provided in the ice maker of the refrigerator according to the spirit of the present disclosure, and the spirit of the present disclosure is not limited thereto.

FIG. 11 is a view for describing an operation of the second ice making unit of the refrigerator according to one or more embodiments of the present disclosure.

One example of the second ice making unit 1400 included in the ice maker 1000 of the refrigerator 1 will be described with reference to FIGS. 8 to 11.

Referring to FIGS. 8 to 11, the second ice making unit 1400 may be configured to form a second type of ice having a substantially spherical shape.

The second ice making unit 1400 may include a second ice making tray 1410 in which ice is formed.

The second ice making tray 1410 may include at least one second ice making cell configured to store water received from the water supply 80 (see FIG. 2). The water stored in the second ice making cell may be converted into ice by cold air of the storage compartment 20. The second ice making cell may be provided inside the second ice making tray 1410. The second ice making cell may be configured to include an elastic material. The second ice making cell may be provided to be elastically deformable.

The second ice making unit 1400 may include a cover frame 1450 configured to cover an outer side of the second ice making tray 1410. The cover frame 1450 may be supported by the second ice making unit support portion 1242. The second ice making tray 1410 may be supported by the cover frame 1450.

The cover frame 1450 may include a water collector 1452 configured to receive water from the water supply 80. The water collector 1452 may be provided to collect water supplied from the water supply 80 and supply the water to the second ice making tray 1410.

As illustrated in FIGS. 8 to 11, the second ice making tray 1410 may be provided to simultaneously form a plurality of pieces of the second type of ice. A plurality of second ice making cells may be provided inside the second ice making tray 1410. For example, the water collector 1452 may be provided as a plurality of water collectors 1452 to correspond to the number of the plurality of second ice making cells and may supply collected water to each of the plurality of second ice making cells. For example, the water collector 1452 may supply the collected water to only some of the plurality of second ice making cells, and the plurality of second ice making cells may be formed to communicate with each other so that the collected water can be supplied into all of the second ice making cells.

The second ice making tray 1410 may include a fixed tray 1411 and a movable tray 1412. The fixed tray 1411 and the movable tray 1412 may be supported by the cover frame 1450.

The fixed tray 1411 may maintain fixed relative to the cover frame 1450. The movable tray 1412 may be provided to be movable relative to the cover frame 1450. More specifically, the movable tray 1412 may be provided to be movable between the fixed tray 1411 and a second ejector 1440.

One portion of a second ice making cell that corresponds to substantially a half of the second ice making cell may be provided inside the fixed tray 1411. The other portion of the second ice making cell that corresponds to substantially the other half of the second ice making cell may be provided inside the movable tray 1412. The one portion of the second ice making cell inside the fixed tray 1411 and the other portion of the second ice making cell inside the movable tray 1412 may each be formed to include a substantially semi-spherical shape.

The second ice making unit 1400 may include a second driving portion 1420 configured to provide power so that the movable tray 1412 is movable relative to the cover frame 1450 and ejectors 1430 and 1440 configured to discharge ice formed in the second ice making tray 1410 from the second ice making tray 1410.

The second driving portion 1420 may include a motor configured to generate power, a motor case 1421 configured to accommodate the motor, and a power transmission member 1422 configured to transmit the power generated by the motor. For example, the motor of the second driving portion 1420 may generate power for rotation about the axis of rotation in the horizontal direction of the refrigerator 1.

The motor case 1421 may be coupled to the cover frame 1450. The motor case 1421 may be coupled to a second driving coupling portion 1451 provided at the cover frame 1450. A hole passing through the cover frame 1450 may be formed in the second driving coupling portion 1451, and the hole of the second driving coupling portion 1451 may be disposed in a rotating shaft connected to the motor of the second driving portion 1420.

The power transmission member 1422 may be connected to the motor of the second driving portion 1420 and receive power generated by the motor. The power transmission member 1422 may transmit the power received from the motor to the movable tray 1412. For example, the power transmission member 1422 may include at least one gear.

The power transmission member 1422 may be provided to covert rotary motion by the motor of the second driving portion 1420 into linear motion and transmit the linear motion to the movable tray 1412. For example, the power transmission member 1422 may include a pinion gear and a rack gear. The pinion gear of the power transmission member 1422 may be connected to the rotating shaft of the motor of the second driving portion 1420. The pinion gear of the power transmission member 1422 may be engaged with the rack gear, and the rotary motion of the pinion gear may be converted into linear motion of the rack gear.

The rack gear of the power transmission member 1422 may be coupled to the movable tray 1412. The movable tray 1412 may be provided to move linearly relative to the cover frame 1450 due to the linear motion of the rack gear.

The power transmission member 1422 may further include an elastic member 1423. The elastic member 1423 may couple the rack gear of the power transmission member 1422 to the movable tray 1412. For example, the elastic member 1423 may be an elastic spring.

The ejectors 1430 and 1440 of the second ice making unit 1400 may include a first ejector 1430 and a second ejector 1440. The first ejector 1430 may be provided at a position adjacent to the fixed tray 1411. The second ejector 1440 may be provided at a position adjacent to the movable tray 1412. The second ice making tray 1410 may be disposed between the first ejector 1430 and the second ejector 1440.

The first ejector 1430 may be provided to be movable relative to the cover frame 1450. The first ejector 1430 may be provided to be movable based on the movement of the movable tray 1412.

The first ejector 1430 may include a first body 1431, a first pressing portion 1432, and a leg portion 1433.

The first body 1431 may be formed to extend in a direction parallel to the movable tray 1412. That is, the first body 1431 may extend in a direction perpendicular to a direction in which the first ejector 1430 moves.

The first pressing portion 1432 may be provided to extend from the first body 1431. The first body 1431 may be provided to support the first pressing portion 1432. The first pressing portion 1432 may be provided to pass through the fixed tray 1411 and press the second ice making cell inside the fixed tray 1411.

The leg portion 1433 may extend from both ends of the first body 1431 and be inserted into a side portion of the cover frame 1450. The leg portion 1433 may extend in a direction parallel to the direction in which the first ejector 1430 moves. The leg portion 1433 may be provided as a pair of leg portions 1433 symmetrical to each other.

When the movable tray 1412 moves in a direction moving away from the fixed tray 1411, the first ejector 1430 may move in the direction in which the movable tray 1412 moves. That is, since the fixed tray 1411 is disposed between the first ejector 1430 and the movable tray 1412, the first ejector 1430 may move in a direction approaching the fixed tray 1411.

Also, when the movable tray 1412 moves in a direction approaching the fixed tray 1411, the first ejector 1430 may also move in the direction in which the movable tray 1412 moves. That is, since the fixed tray 1411 is disposed between the first ejector 1430 and the movable tray 1412, the first ejector 1430 may move in a direction moving away from the fixed tray 1411.

For example, the movable tray 1412 may include an interference portion provided to interfere with the leg portion 1433 of the first ejector 1430, and according to movement of the movable tray 1412, the interference portion of the movable tray 1412 and the leg portion 1433 may interfere with each other, and the first ejector 1430 may also move together.

The first pressing portion 1432 of the first ejector 1430 may be provided to, while the first ejector 1430 moves toward the fixed tray 1411, pass through the fixed tray 1411 and press the second ice making cell inside the fixed tray 1411.

The second ejector 1440 may be fixed to one side of the cover frame 1450.

The second ejector 1440 may include a second body 1441, a second pressing portion 1442, and a frame coupling portion 1443. The second body 1441 may extend in the direction parallel to the movable tray 1412. The second pressing portion 1442 may extend from the second body 1441 toward the movable tray 1412. The frame coupling portion 1443 may be formed at both ends of the second body 1441 and coupled to the cover frame 1450.

The second ejector 1440 may maintain fixed relative to the cover frame 1450 and be provided to, while the movable tray 1412 moves toward the second ejector 1440, press the movable tray 1412. More specifically, the second ejector 1440 may be provided to, while the movable tray 1412 moves toward the second ejector 1440, press the second ice making cell inside the movable tray 1412.

As illustrated in FIG. 9, while the second ice making tray 1410 forms ice using water received from the water supply 80, the fixed tray 1411 and the movable tray 1412 may be positioned to be coupled to each other. At the position at which the fixed tray 1411 and the movable tray 1412 are coupled, the one portion of the second ice making cell inside the fixed tray 1411 and the other portion of the second ice making cell inside the movable tray 1412 may be coupled and constitute a single second ice making cell, and the second type of ice may be formed inside the second ice making cell.

After the formation of the second type of ice is completed, as illustrated in FIGS. 10 and 11, the controller may control driving of the second driving portion 1420 so that the movable tray 1412 moves toward the second ejector 1440. When power is generated by the motor of the second driving portion 1420, the generated power may be transmitted to the movable tray 1412 through the power transmission member 1422. The movable tray 1412 may be separated from the fixed tray 1411 and linearly move toward the second ejector 1440.

The second pressing portion 1442 of the second ejector 1440 may be provided to, when the movable tray 1412 approaches, pass through the movable tray 1412 and press the portion of the second ice making cell inside the movable tray 1412. The portion of the second ice making cell inside the movable tray 1412 may be elastically deformed when pressed by the second pressing portion 1442, and the second type of ice placed therein may be discharged from the movable tray 1412. The second type of ice discharged from the movable tray 1412 may move to the second accommodating portion 120 of the ice bucket 100.

When the movable tray 1412 moves further in the same direction in the state in which the portion of the second ice making cell inside the movable tray 1412 is pressed by the second pressing portion 1442, as the interference portion of the movable tray 1412 and the leg portion 1433 interfere with each other, the first ejector 1430 may move toward the fixed tray 1411. Accordingly, the first pressing portion 1432 of the first ejector 1430 may be provided to pass through the fixed tray 1411 and press the other portion of the second ice making cell inside the fixed tray 1411. The other portion of the second ice making cell inside the fixed tray 1411 may be elastically deformed when pressed by the first pressing portion 1432, and the second type of ice placed therein may be discharged from the fixed tray 1411. The second type of ice discharged from the fixed tray 1411 may move to the second accommodating portion 120 of the ice bucket 100.

By the above configuration, ice formed in the second ice making tray 1410 may be discharged from the second ice making tray 1410 and move to the second accommodating portion 120 of the ice bucket 100.

The configuration relating to the second ice making unit 1400 described above with reference to FIGS. 8 to 11 is only one example of an ice making unit provided in the ice maker of the refrigerator according to the spirit of the present disclosure, and the spirit of the present disclosure is not limited thereto.

Further, as an embodiment of the ice maker of the refrigerator according to the spirit of the present disclosure, a structure relating to an indirect-cooling ice maker that guides cold air generated in the storage compartment 20 toward the ice maker 1000 to cool water supplied to the first and second ice making trays 1310 and 1410 has been described above as an example with reference to FIGS. 1 to 11. However, the spirit of the present disclosure is not limited thereto, and for example, the spirit of the present disclosure may also apply to a configuration of a direct-cooling ice maker in which a separate refrigerant pipe is placed in the first and second ice making trays 1310 and 1410 to directly provide cold air thereto and cool water supplied to the first and second ice making trays 1310 and 1410.

FIG. 12 is an enlarged view of a partial configuration of the ice maker of the refrigerator according to one or more embodiments of the present disclosure. FIG. 13 is a cut-open cross-sectional view of the ice maker of the refrigerator according to one or more embodiments of the present disclosure. FIG. 14 is an enlarged view of A of FIG. 13. FIG. 15 is a cross-sectional view illustrating a state in which the ice maker is mounted in the inner case of the refrigerator according to one or more embodiments of the present disclosure. FIG. 16 is an enlarged cross-sectional view of B of FIG. 15. FIG. 17 is an enlarged cross-sectional view of a state in which an inner wall of the inner case is deformed in FIG. 16.

Referring to FIGS. 12 to 17, the ice maker case 1200 of the ice maker 1000 may include elastic protrusions 1220a and 1220b provided on the ice maker case walls 1210a and 1210b.

As described above, the ice maker case 1200 may include the first ice maker case wall 1210a supported by the first inner wall 11a of the inner case 11 and the second ice maker case wall 1210b supported by the second inner wall 11b of the inner case 11. The first ice maker case wall 1210a and the second ice maker case wall 1210b may each constitute an outer wall of the ice maker case 1200 in the left-right direction of the ice maker 1000.

When the ice maker 1000 is mounted in the inner case 11aa illustrated in FIGS. 15 to 17, an error may occur in the dimension of the ice maker case 1200 and the dimension of the inner case 11. Such an error may occur due to reasons such as limitations in the design and manufacture of the inner case 11 and limitations in the design and manufacture of the ice maker case 1200. Alternatively, after the body insulator 13 is foamed between the inner case 11 and the outer case 12 as illustrated in FIG. 17, deformation may occur in the shape of the foamed body insulator 13. Alternatively, even after the ice maker 1000 is mounted in the inner case 11, deformation may occur in the inner walls 11a and 11b of the inner case 11, the ice maker case 1200 of the ice maker 1000, or the like.

In a case in which an error occurs in the dimension of the ice maker case 1200 and the dimension of the inner case 11aa above, an error may occur in implementing the positions of the first inner wall 11a and the first ice maker case wall 1210a relative to each other, the positions of the second inner wall 11b and the second ice maker case wall 1210b relative to each other, and the like, as per the design. Accordingly, the ice maker 1000 may not be properly supported by the inner walls 11a and 11b of the inner case 11.

Also, due to the positions of the first inner wall 11a and the first ice maker case wall 1210a relative to each other, the positions of the second inner wall 11b and the second ice maker case wall 1210b relative to each other, and the like not being implemented as per the design, the exterior quality of the ice maker 1000 that is viewed by the user looking at the ice maker 1000 mounted in the inner case 11 may be degraded. For example, as the positions of the inner walls 11a and 11b and the ice maker case walls 1210a and 1210b relative to each other are not implemented as per the design, the front portion 1230 of the ice maker case 1200 may be positioned to be inclined relative to the horizontal direction of the refrigerator 1. Since the front portion 1230 forms the exterior of the front of the ice maker 1000, the exterior quality of the ice maker 1000 may be degraded.

Also, while the ice maker 1000 is being mounted in the inner case 11, in the process in which the ice maker case walls 1210a and 1210b of the ice maker case 1200 are brought into contact with the inner walls 11a and 11b, scratching may occur between the ice maker case 1200 and the inner walls 11a and 11b of the inner case 11, and damage to the ice maker 1000 or the inner case 11 may occur. This may become more of an issue in the case in which an error occurs in the dimension of the ice maker case 1200 and the dimension of the inner case 11. This may be an issue during the process of mounting the ice maker 1000 in the inner case 11, or even after the ice maker 1000 is mounted in the inner case 11, this may be an issue due to deformation in the ice maker case 1200, the inner case 11, the body insulator 13, or the like.

In order to address such an issue, the ice maker case 1200 may include the elastic protrusions 1220a and 1220b provided to interfere with the inner walls 11a and 11b of the inner case 11 and be elastically deformable.

Specifically, the ice maker case 1200 may include a first elastic protrusion 1220a provided on the first ice maker case wall 1210a. The first elastic protrusion 1220a may interfere with the first inner wall 11a. The first elastic protrusion 1220a may be provided to be elastically deformable in a direction in which the first elastic protrusion 1220a is pressed by the first inner wall 11a.

The first elastic protrusion 1220a may be provided at the right side of the ice maker case 1200 when viewed from the front. The first elastic protrusion 1220a may have a shape that protrudes to the right of the ice maker case 1200 when viewed from the front.

The first elastic protrusion 1220a may be provided to be pressed in a direction from the first inner wall 11a of the inner case 11 toward the ice maker case 1200. The first elastic protrusion 1220a may be provided to be pressed in a direction from the first inner wall 11a of the inner case 11 toward the first ice maker case wall 1210a. In other words, the first elastic protrusion 1220a may be provided to be pressed in a direction from the first inner wall 11a of the inner case 11 toward the second inner wall 11b. As illustrated in FIGS. 12 to 17, the first elastic protrusion 1220a may be pressed toward the inside of the storage compartment 20 in the left-right direction by the first inner wall 11a.

Due to being pressed, the first elastic protrusion 1220a may be provided to be elastically deformable. That is, the first elastic protrusion 1220a may be provided to be elastically deformable in the direction in which the first elastic protrusion 1220a is pressed by the first inner wall 11a.

Since the first elastic protrusion 1220a is elastically deformable, the position of the first ice maker case wall 1210a relative to the first inner wall 11a may also be adjustable. Since the position of the first ice maker case wall 1210a relative to the first inner wall 11a is adjustable, the position of the ice maker case 1200 relative to the inner case 11 may be adjustable.

For example, as illustrated in FIGS. 13 and 14, in a state in which the ice maker 1000 is not mounted in the inner case 11, the first elastic protrusion 1220a may be in a non-elastically-deformed state due to not interfering with the first inner wall 11a and not being pressed by the first inner wall 11a. In this case, based on FIGS. 13 and 14, a right side end of the first elastic protrusion 1220a may protrude to be positioned more to the right than an outer surface of the first ice maker case wall 1210a.

For example, as illustrated in FIGS. 15 and 16, in a state in which the ice maker 1000 is mounted in the inner case 11, the first elastic protrusion 1220a may interfere with the first inner wall 11a and be pressed by the first inner wall 11a. Here, the first elastic protrusion 1220a may be elastically deformed, and the right side end of the first elastic protrusion 1220a may move to be positioned more to the left than the position thereof in FIGS. 13 and 14. In other words, the first elastic protrusion 1220a may be elastically deformed so that an end thereof facing the first inner wall 11a, that is, an end thereof coming in contact with the first inner wall 11a, moves toward the inside of the storage compartment 20 in the left-right direction.

For example, as illustrated in FIG. 17, in the state in which the ice maker 1000 is mounted in the inner case 11, the first inner wall 11a may be deformed due to reasons such as deformation of the body insulator 13. For example, when deformation occurs in the body insulator 13 such that the volume of the body insulator 13 increases, the first inner wall 11a may be deformed in the direction toward the inside of the storage compartment 20 in the left-right direction. Accordingly, a degree to which the first elastic protrusion 1220a is pressed by the first inner wall 11a may increase, and a degree to which the first elastic protrusion 1220a is elastically deformed may increase as compared to the degree illustrated in FIGS. 15 and 16.

Since the exterior of the ice maker 1000 that is visible to the user is mostly the exterior of the front of the ice maker 1000, the positions of the first ice maker case wall 1210a and the first inner wall 11a relative to each other may be adjusted at least from the front. Accordingly, the first elastic protrusion 1220a may be disposed to be more adjacent to the opening 10a of the inner case 11 than to the rear wall 11c of the inner case 11. More specifically, the first elastic protrusion 1220a may be disposed in front of the first ice maker case wall 1210a and disposed to be adjacent to the front portion 1230 of the ice maker case 1200. However, the present disclosure is not limited thereto, and the first elastic protrusion 1220a may be provided at various other positions. For example, the first elastic protrusion 1220a may be disposed to be adjacent to the rear wall 11c of the inner case 11. Alternatively, for example, the first elastic protrusion 1220a may be provided at a position almost equally distant from each of the opening 10a and the rear wall 11c of the inner case 11.

In the state in which the ice maker 1000 is mounted in the inner case 11, the first elastic protrusion 1220a may be disposed not to directly interfere with the first holder 11aa. In other words, the first elastic protrusion 1220a may be disposed to interfere with a position on the first inner wall 11a where the first holder 11aa is not provided.

For example, as illustrated in FIGS. 15 to 17, the first elastic protrusion 1220a may be provided under the first holder 11aa. Specifically, although the first elastic protrusion 1220a may be disposed under the first holder 11aa in the vertical direction, the present disclosure is not limited thereto, and the first elastic protrusion 1220a may be disposed in a direction moved in the forward-backward direction from under the first holder 11aa in the vertical direction. That is, the first elastic protrusion 1220a may be disposed in a diagonal direction.

For example, unlike in FIGS. 15 to 17, the first elastic protrusion 1220a may be provided above the first holder 11aa.

However, the present disclosure is not limited thereto, and the first elastic protrusion 1220a may be disposed to interfere with the first holder 11aa.

The ice maker case 1200 may include a second elastic protrusion 1220b provided on the second ice maker case wall 1210b. The second elastic protrusion 1220b may interfere with the second inner wall 11b. The second elastic protrusion 1220b may be provided to be elastically deformable in a direction in which the second elastic protrusion 1220b is pressed by the second inner wall 11b.

The second elastic protrusion 1220b may be provided at the left side of the ice maker case 1200 when viewed from the front. The second elastic protrusion 1220b may have a shape that protrudes to the left of the ice maker case 1200 when viewed from the front.

The second elastic protrusion 1220b may be provided to be pressed in a direction from the second inner wall 11b of the inner case 11 toward the ice maker case 1200. The second elastic protrusion 1220b may be provided to be pressed in a direction from the second inner wall 11b of the inner case 11 toward the second ice maker case wall 1210b. In other words, the second elastic protrusion 1220b may be provided to be pressed in a direction from the second inner wall 11b of the inner case 11 toward the first inner wall 11a. As illustrated in FIGS. 12 to 17, the second elastic protrusion 1220b may be pressed toward the inside of the storage compartment 20 in the left-right direction by the second inner wall 11b.

Due to being pressed, the second elastic protrusion 1220b may be provided to be elastically deformable. That is, the second elastic protrusion 1220b may be provided to be elastically deformable in the direction in which the second elastic protrusion 1220b is pressed by the second inner wall 11b.

Since the second elastic protrusion 1220b is elastically deformable, the position of the second ice maker case wall 1210b relative to the second inner wall 11b may also be adjustable. Since the position of the second ice maker case wall 1210b relative to the second inner wall 11b is adjustable, the position of the ice maker case 1200 relative to the inner case 11 may be adjustable.

For example, as illustrated in FIG. 13, in the state in which the ice maker 1000 is not mounted in the inner case 11, the second elastic protrusion 1220b may be in a non-elastically-deformed state due to not interfering with the second inner wall 11b and not being pressed by the second inner wall 11b. In this case, based on FIG. 13, a left side end of the second elastic protrusion 1220b may protrude to be positioned more to the left than an outer surface of the second ice maker case wall 1210b.

For example, as illustrated in FIG. 15, in the state in which the ice maker 1000 is mounted in the inner case 11, the second elastic protrusion 1220b may interfere with the second inner wall 11b and be pressed by the second inner wall 11b. Here, the second elastic protrusion 1220b may be elastically deformed, and the left side end of the second elastic protrusion 1220b may move to be positioned more to the right than the position thereof in FIG. 13. In other words, the second elastic protrusion 1220b may be elastically deformed so that an end thereof facing the second inner wall 11b, that is, an end thereof coming in contact with the second inner wall 11b, moves toward the inside of the storage compartment 20 in the left-right direction.

For example, as illustrated in FIG. 17, as in the above description of the first elastic protrusion 1220a, in the state in which the ice maker 1000 is mounted in the inner case 11, the second inner wall 11b may be deformed due to reasons such as deformation of the body insulator 13. For example, when deformation occurs in the body insulator 13 such that the volume of the body insulator 13 increases, the second inner wall 11b may be deformed in the direction toward the inside of the storage compartment 20 in the left-right direction. Accordingly, a degree to which the second elastic protrusion 1220b is pressed by the second inner wall 11b may increase, and a degree to which the second elastic protrusion 1220b is elastically deformed may increase as compared to the degree illustrated in FIG. 15.

Since the exterior of the ice maker 1000 that is visible to the user is mostly the exterior of the front of the ice maker 1000, the positions of the second ice maker case wall 1210b and the second inner wall 11b relative to each other may be adjusted at least from the front. Accordingly, the second elastic protrusion 1220b may be disposed to be more adjacent to the opening 10a of the inner case 11 than to the rear wall 11c of the inner case 11. More specifically, the second elastic protrusion 1220b may be disposed in front of the second ice maker case wall 1210b and disposed to be adjacent to the front portion 1230 of the ice maker case 1200. However, the present disclosure is not limited thereto, and the second elastic protrusion 1220b may be provided at various other positions. For example, the second elastic protrusion 1220b may be disposed to be adjacent to the rear wall 11c of the inner case 11. Alternatively, for example, the second elastic protrusion 1220b may be provided at a position almost equally distant from each of the opening 10a and the rear wall 11c of the inner case 11.

In the state in which the ice maker 1000 is mounted in the inner case 11, the second elastic protrusion 1220b may be disposed not to directly interfere with the second holder 11bb. In other words, the second elastic protrusion 1220b may be disposed to interfere with a position on the second inner wall 11b where the second holder 11bb is not provided.

For example, as illustrated in FIG. 15, the second elastic protrusion 1220b may be provided under the second holder 11bb. Specifically, although the second elastic protrusion 1220b may be disposed under the second holder 11bb in the vertical direction, the present disclosure is not limited thereto, and the second elastic protrusion 1220b may be disposed in a direction moved in the forward-backward direction from under the second holder 11bb in the vertical direction. That is, the second elastic protrusion 1220b may be disposed in a diagonal direction.

For example, unlike in FIG. 15, the second elastic protrusion 1220b may be provided above the second holder 11bb.

However, the present disclosure is not limited thereto, and the second elastic protrusion 1220b may be disposed to interfere with the second holder 11bb.

In this way, the first elastic protrusion 1220a and the second elastic protrusion 1220b may be provided to be elastically deformable so that the position of the ice maker case 1200 relative to the first inner wall 11a and the second inner wall 11b is adjustable.

By the above configuration, the ice maker 1000 includes the elastic protrusions 1220a and 1220b and thus may be stably supported by the inner walls 11a and 11b of the inner case 11. Also, since the elastic protrusions 1220a and 1220b are elastically deformable in the directions in which the elastic protrusions 1220a and 1220b are pressed by the inner walls 11a and 11b, the elastic protrusions 1220a and 1220b may prevent damage to the ice maker 1000 and the inner walls 11a and 11b of the inner case 11. Also, by the elastic protrusions 1220a and 1220b, the position of the ice maker 1000 relative to the inner case 11 may be adjusted, and the exterior quality of the product may be improved.

Although description has been given above assuming that the ice maker case 1200 includes the first elastic protrusion 1220a provided on the first ice maker case wall 1210a and configured to interfere with the first inner wall 11a of the inner case 11 and the second elastic protrusion 1220b provided on the second ice maker case wall 1210b and configured to interfere with the second inner wall 11b of the inner case 11, the spirit of the present disclosure is not limited thereto.

For example, the ice maker case 1200 may include only the elastic protrusion 1220a provided on the first ice maker case wall 1210a and configured to interfere with the first inner wall 11a of the inner case 11. The elastic protrusion 1220a may be provided so that the position thereof between the first inner wall 11a and the first ice maker case wall 1210a is adjustable. Accordingly, even in such a case, the elastic protrusion 1220a may be provided to adjust the position of the ice maker case 1200 relative to the inner case 11, and it is possible to provide an advantageous effect according to the spirit of the present disclosure.

On the other hand, for example, the ice maker case 1200 may include only the elastic protrusion 1220b provided on the second ice maker case wall 1210b and configured to interfere with the second inner wall 11b of the inner case 11. The elastic protrusion 1220b may be provided so that the position thereof between the second inner wall 11b and the second ice maker case wall 1210b is adjustable. Accordingly, even in such a case, the elastic protrusion 1220b may be provided to adjust the position of the ice maker case 1200 relative to the inner case 11, and it is possible to provide an advantageous effect according to the spirit of the present disclosure.

The first ice maker case wall 1210a and the second ice maker case wall 1210b may have configurations that are the same as each other or at least correspond to each other.

Accordingly, hereinafter, the description of the second ice maker case wall 1210b may be omitted, and the first ice maker case wall 1210a may be referred to as an ice maker case wall 1210a. The description of the configuration of the ice maker case wall 1210a may also apply correspondingly to the configuration of the second ice maker case wall 1210b.

Also, the first elastic protrusion 1220a and the second elastic protrusion 1220b may have configurations that are the same as each other or at least correspond to each other.

Accordingly, hereinafter, the description of the second elastic protrusion 1220b may be omitted, and the first elastic protrusion 1220a may be referred to as an elastic protrusion 1220a. The description of the configuration of the elastic protrusion 1220a may also apply correspondingly to the configuration of the second elastic protrusion 1220b.

Hereinafter, the configuration of the elastic protrusion 1220a of the ice maker case 1200 will be described in detail with reference to FIGS. 12 to 17.

The elastic protrusion 1220a may include an interference portion 1221a provided to interfere with the first inner wall 11a. The interference portion 1221a may protrude in a first direction X from the first ice maker case wall 1210a toward the first inner wall 11a.

The interference portion 1221a may be provided to be movable in a direction parallel to the first direction X by being elastically deformed. Specifically, the interference portion 1221a and the first inner wall 11a may come in contact with each other in the direction parallel to the first direction X, and the interference portion 1221a may be pressed in the direction parallel to the first direction X by the first inner wall 11a. The interference portion 1221a may be provided to be movable in the direction parallel to the first direction X when pressed by the first inner wall 11a.

For example, when the ice maker 1000 is mounted in the inner case 11 (when the state of FIGS. 13 and 14 changes to the state of FIGS. 15 and 16), the interference portion 1221a may move toward the inside of the storage compartment 20 in the first direction X. For example, when the first inner wall 11a is deformed in the state in which the ice maker 1000 is mounted in the inner case 11, the interference portion 1221a may move toward the inside of the storage compartment 20 in the first direction X according to the deformation of the first inner wall 11a (when the state of FIGS. 15 and 16 changes to the state of FIG. 17), or the interference portion 1221a may move toward the outside of the storage compartment 20 in the first direction X (when the state of FIG. 17 changes to the state of FIGS. 15 and 16). That is, the degree of elastic deformation of the elastic protrusion 1220a may vary according to the degree to which the elastic protrusion 1220a is pressed by the first inner wall 11a, and the degree to which the interference portion 1221a moves in the direction parallel to the first direction X may also vary according to the degree of elastic deformation.

For example, the first direction X may be a direction parallel to the left-right direction of the inner case 11.

The interference portion 1221a may extend in a second direction Y different from the first direction X. The second direction Y may be a direction parallel to the first inner wall 11a. In other words, the interference portion 1221a may extend in the second direction Y which is a direction parallel to the direction in which the first inner wall 11a extends.

For example, the second direction Y may be a direction orthogonal to the first direction X. For example, the second direction Y may be a direction parallel to the forward-backward direction of the inner case 11.

Since the interference portion 1221a has a shape protruding in the first direction X and extends in the second direction Y parallel to the first inner wall 11a, when interfering with the first inner wall 11a, the interference portion 1221a may distribute pressure applied to the interference portion 1221a or the first inner wall 11a. Further, when interfering with the first inner wall 11a, the interference portion 1221a may prevent damage to the interference portion 1221a or the first inner wall 11a.

The interference portion 1221a may include a contact surface 1221as1 and a corner surface 1221as2. The contact surface 1221as1 and the corner surface 1221as2 may be provided at one end of the interference portion 1221a in the first direction X. The contact surface 1221as1 and the corner surface 1221as2 may be provided at one end of the interference portion 1221a that faces the first inner wall 11a.

The contact surface 1221as1 may be provided at one end of the interference portion 1221a in the first direction X and provided to come in contact with the first inner wall 11a. The contact surface 1221as1 may be one surface of the interference portion 1221a that comes in contact with the first inner wall 11a.

The position at which the contact surface 1221as1 is provided at the interference portion 1221a may vary according to the direction in which the interference portion 1221a comes in contact with the first inner wall 11a. For example, the contact surface 1221as1 may be provided at one end of the interference portion 1221a in the left-right direction.

The corner surface 1221as2 may be bent from an end of the contact surface 1221as1 in the second direction Y and extend. The corner surface 1221as2 may be formed to be inclined relative to the second direction Y. The corner surface 1221as2 may be bent from the end of the contact surface 1221as1 in the second direction Y and extend in a direction inclined relative to the second direction Y. The corner surface 1221as2 may extend from the contact surface 1221as1 in a direction moving away from the first inner wall 11a.

As illustrated in FIG. 12 and so on, the corner surface 1221as2 may be bent from both ends of the contact surface 1221as1 in the second direction Y and extend. For example, the corner surface 1221as2 may be bent from each of a front end and a rear end of the contact surface 1221as1 and extend in a direction inclined relative to the forward-backward direction. However, the present disclosure is not limited thereto, and for example, the corner surface 1221as2 may be bent from one end of the contact surface 1221as1 in the second direction Y and extend. For example, the corner surface 1221as2 may extend from the rear end of the contact surface 1221as1. The corner surface 1221as2 may extend to be inclined in a direction toward the inside of the storage compartment 20 in the first direction X from an end of the contact surface 1221as1 in the second direction.

For example, one end of the interference portion 1221a in the first direction X may be provided to include the shape of a curved surface. The contact surface 1221as1 and the corner surface 1221as2 may be formed to be connected to each other and constitute a single curved surface shape together (refer to an upper elastic protrusion 1220aa of FIG. 12).

For example, the contact surface 1221as1 may extend in the second direction Y, and the corner surface 1221as2 may extend to be inclined relative to the direction in which the contact surface 1221as1 extends (refer to a lower elastic protrusion 1220ab of FIG. 12). The contact surface 1221as1 may longitudinally extend in the second direction Y. A radius of curvature of the contact surface 1221as1 and a radius of curvature of the corner surface 1221as2 may be provided to be different from each other, and more specifically, the radius of curvature of the contact surface 1221as1 may be provided to be greater than the radius of curvature of the corner surface 1221as2.

However, the present disclosure is not limited thereto, and the contact surface 1221as1 and the corner surface 1221as2 may be formed to have various other shapes.

According to the above configuration, the corner surface 1221as2 may be provided to not come in direct contact with the first inner wall 11a. In particular, when the ice maker 1000 is mounted in the inner case 11 by being inserted thereinto in the second direction Y, the contact surface 1221as1 may come in contact and interfere with the first inner wall 11a, but the corner surface 1221as2 may not come in contact with the first inner wall 11a. That is, when the ice maker 1000 is being mounted in the inner case 11 by sliding in the second direction Y, due to the shape of the corner surface 1221as2, a corner portion of the interference portion 1221a may be prevented from interfering with the first inner wall 11a, and damage to the first inner wall 11a or the elastic protrusion 1220a due to the first inner wall 11a and the elastic protrusion 1220a being scratched against each other may be prevented.

However, the spirit of the present disclosure is not limited thereto, and the interference portion of the elastic protrusion according to one or more embodiments of the present disclosure may be formed to have various other shapes that allow the interference portion to interfere with the inner wall of the inner case.

Although the second direction Y in which the interference portion 1221a extends is illustrated as being parallel to the forward-backward direction of the inner case 11 in FIGS. 12 to 17, unlike in FIGS. 12 to 17, for example, the second direction in which the interference portion 1221a extends may be parallel to the up-down direction of the inner case 11. Further, the corner surface 1221as2 may be bent from an end of the contact surface 1221as1 in the up-down direction and extend. In this case, while the ice maker 1000 is being mounted in the inner case 11, as long as the ice maker 1000 is inserted into the inner case 11 in the up-down direction, it is possible to prevent damage to the elastic protrusion 1220a or the first inner wall 11a that is caused by scratching between the elastic protrusion 1220a and the first inner wall 11a.

The elastic protrusion 1220a may include a connecting portion 1222a configured to be connected to the ice maker case wall 1210a. The connecting portion 1222a may connect the ice maker case wall 1210a and the interference portion 1221a to each other.

The connecting portion 1222a may include a fixed end 1222ae1 configured to be fixed to the ice maker case wall 1210a. The connecting portion 1222a may be provided to be elastically deformable relative to the fixed end 1222ae1. The connecting portion 1222a may be provided to be elastically deformable about the fixed end 1222ae1.

The connecting portion 1222a may include a free end 1222ae2 opposing the fixed end 1222ae1. The free end 1222ae2 may not maintain fixed relative to the ice maker case wall 1210a. The free end 1222ae2 may be one end of the connecting portion 1222a that is connected to the interference portion 1221a. The above-described interference portion 1221a may extend in the first direction X from the free end 1222ae2. The interference portion 1221a may extend from the free end 1222ae2 toward the first inner wall 11a.

The connecting portion 1222a may extend between the fixed end 1222ae1 and the free end 1222ae2. The connecting portion 1222a may be provided to extend in a direction different from the direction in which the elastic protrusion 1220a is pressed by the first inner wall 11a. More specifically, the interference portion 1221a may be provided to be pressed in the first direction X by the first inner wall 11a, and the connecting portion 1222a may be provided to extend from the fixed end 1222ae1 in a direction different from the first direction X.

For example, the connecting portion 1222a may extend from the fixed end 1222ae1 toward the free end 1222ae2 in a third direction Z orthogonal to the first direction X and the second direction Y. For example, the third direction Z may be parallel to the up-down direction of the inner case 11. That is, the fixed end 1222ae1 may be formed above the free end 1222ae2, and the connecting portion 1222a may have an upper end fixed to the ice maker case wall 1210a and a lower end fixed to the interference portion 1221a to be movable according to elastic deformation.

However, the present disclosure is not limited thereto, and the connecting portion 1222a may extend in various other directions from the fixed end 1222ae1 toward the free end 1222ae2.

The connecting portion 1222a may be configured to include an elastic material. By including an elastic material, the connecting portion 1222a may be provided to be elastically deformed about the fixed end 1222ae1 in response to an external force being applied to the free end 1222ae2 in a state in which the fixed end 1222ae1 is fixed to the ice maker case wall 1210a. For example, the connecting portion 1222a may be configured to include a plastic material. However, the present disclosure is not limited thereto, and the connecting portion 1222a may be configured to include various other materials that allow the connecting portion 1222a to be elastically deformable.

As described above, the interference portion 1221a may have a shape that protrudes in the first direction X to interfere with the first inner wall 11a. Here, the connecting portion 1222a may extend from the fixed end 1222ae1 toward the free end 1222ae2, and the interference portion 1221a may be bent from the free end 1222ae2 of the connecting portion 1222a and extend in the first direction X. For example, as illustrated in FIG. 12 and so on, the connecting portion 1222a may extend in the third direction Z, and the interference portion 1221a may be bent from the free end 1222ae2 and extend in the first direction X.

The interference portion 1221a may be integrally formed with the connecting portion 1222a. In the case in which the connecting portion 1222a is configured to include an elastic material, the interference portion 1221a may be configured to include an elastic material like the connecting portion 1222a.

However, the present disclosure is not limited thereto, and the elastic protrusion 1220a including the interference portion 1221a and the connecting portion 1222a may be formed in various other ways.

The ice maker case wall 1210a may include a cut-open portion 1211a. The cut-open portion 1211a may be formed to be cut open in the direction in which the connecting portion 1222a extends.

The connecting portion 1222a may be provided at the cut-open portion 1211a. The connecting portion 1222a may be provided to be disposed in a cut-open area of the cut-open portion 1211a. Specifically, the fixed end 1222ae1 of the connecting portion 1222a may be fixed to the ice maker case wall 1210a at a boundary portion of the cut-open portion 1211a. The free end 1222ae2 may be provided to be movable without being fixed at an inner portion of the cut-open area of the cut-open portion 1211a. According to such a configuration, the connecting portion 1222a may be provided to be elastically deformable.

The cut-open portion 1211a may extend in a direction parallel to the connecting portion 1222a. The cut-open portion 1211a may be cut open in a direction parallel to the direction in which the free end 1222ae2 extends from the fixed end 1222ae1.

The cut-open portion 1211a may extend in the third direction Z. For example, the cut-open portion 1211a may extend in the up-down direction of the inner case 11. However, the present disclosure is not limited thereto, and the cut-open portion 1211a may extend in various other directions according to the shape or the like of the connecting portion 1222a.

Due to the cut-open portion 1211a, portions of the elastic protrusion 1220a other than the fixed end 1222ae1 fixed to the ice maker case wall 1210a may be formed to be spaced apart from the ice maker case wall 1210a. The elastic protrusion 1220a may be fixed to the ice maker case wall 1210a by the fixed end 1222ae1, and the portions of the elastic protrusion 1220a other than the fixed end 1222ae1 may, due to not being restrained by the ice maker case wall 1210a, easily be elastically deformed about the fixed end 1222ae1 upon receiving an external force.

As illustrated in FIGS. 12 to 17, the interference portion 1221a may be provided so that the position of the interference portion 1221a relative to the cut-open portion 1211a changes as the interference portion 1221a is pressed by the first inner wall 11a. The cut-open portion 1211a is one configuration of the ice maker case wall 1210a and may maintain fixed relative to the ice maker case wall 1210a. The interference portion 1221a may be connected to the free end 1222ae2 of the connecting portion 1222a provided at the cut-open portion 1211a, and accordingly, the position of the interference portion 1221a relative to the cut-open portion 1211a may be changed upon the interference portion 1221a receiving an external force. The interference portion 1221a is a configuration coming in contact with the first inner wall 11a, and as the position of the interference portion 1221a relative to the cut-open portion 1211a changes, the position of the ice maker case 1200 relative to the first inner wall 11a may be adjusted.

As illustrated in FIGS. 13 and 14, a difference between the position at which the end of the interference portion 1221a at the contact surface 1221as1 side protrudes from the ice maker case wall 1210a when the ice maker 1000 is not mounted in the inner case 11 and the position at which the end of the interference portion 1221a at the contact surface 1221as1 side protrudes from the ice maker case wall 1210a when the ice maker 1000 is mounted in the inner case 11 may be seen as a length at which the interference portion 1221a and the first inner wall 11a overlap each other when the interference portion 1221a interferes with the first inner wall 11a.

In order to allow sufficient elastic deformation of the connecting portion 1222a, the length of the area where the cut-open portion 1211a is cut open may need to be sufficiently secured. For example, the length of the area where the cut-open portion 1211a is cut open in the third direction Z may be provided to be three times or more of a length at which the interference portion 1221a and the first inner wall 11a overlap each other in the first direction X. However, the relationship between the length of the area where the cut-open portion 1211a is cut open and the length at which the interference portion 1221a and the first inner wall 11a overlap each other is not limited thereto, and the elastic protrusion 1220a may be formed in various other ways.

By the above configuration, the elastic protrusion 1220a may be provided to be elastically deformable when pressed by the first inner wall 11a. However, the configurations described above are only some examples for allowing the elastic protrusion of the ice maker case to be elastically deformed when pressed in the ice maker of the refrigerator according to the spirit of the present disclosure. The configuration for allowing the elastic deformation of the elastic protrusion 1220a is not limited thereto and may be provided in various other ways. Some examples of various embodiments of the configuration provided to allow the elastic deformation of the elastic protrusion 1220a will be described below (see FIGS. 18 to 20).

The elastic protrusion 1220a may be provided as a plurality of elastic protrusions 1220a on the ice maker case wall 1210a. In other words, the first elastic protrusion 1220a may be provided as a plurality of first elastic protrusions 1220a on the first ice maker case wall 1210a. The second elastic protrusion 1220b may be provided as a plurality of second elastic protrusions 1220b on the second ice maker case wall 1210b. Hereinafter, description will be given based on the first ice maker case wall 1210a and the first elastic protrusion 1220a, and the following description may also apply identically to the configuration of the second ice maker case wall 1210b and the second elastic protrusion 1220b.

A plurality of elastic protrusions 1220a may be arranged in the up-down direction. The plurality of elastic protrusions 1220a may include the upper elastic protrusion 1220aa and the lower elastic protrusion 1220ab formed under the upper elastic protrusion 1220aa.

The upper elastic protrusion 1220aa may be provided at an upper portion of the ice maker case wall 1210a. The lower elastic protrusion 1220ab may be provided at a lower portion of the ice maker case wall 1210a.

In a case in which the first holder 11aa supports the upper portion of the ice maker case 1200, the first holder 11aa may be disposed adjacent to at least the upper elastic protrusion 1220aa. The present disclosure is not limited thereto, and the first holder 11aa may be disposed at various other positions.

The upper elastic protrusion 1220aa may be disposed under the first holder 11aa. However, the present disclosure is not limited thereto, and for example, the upper elastic protrusion 1220aa may be disposed above the first holder 11aa. For example, the first holder 11aa may be disposed between the upper elastic protrusion 1220aa and the lower elastic protrusion 1220ab. For example, the lower elastic protrusion 1220ab may be disposed above the first holder 11aa.

The upper elastic protrusion 1220aa and the lower elastic protrusion 1220ab may be formed to have shapes different from each other.

For example, as illustrated in FIG. 12 and so on, a length at which the lower elastic protrusion 1220ab extends in the second direction Y may be formed longer than a length at which the upper elastic protrusion 1220aa extends in the second direction Y. However, the present disclosure is not limited thereto, and for example, the length at which the lower elastic protrusion 1220ab extends in the second direction Y may be formed shorter than the length at which the upper elastic protrusion 1220aa extends in the second direction Y. For example, the length at which the lower elastic protrusion 1220ab extends in the second direction Y may correspond to the length at which the upper elastic protrusion 1220aa extends in the second direction Y.

For example, as illustrated in FIG. 12 and so on, a single interference portion 1221a may be provided at the upper elastic protrusion 1220aa, and a plurality of interference portions 1221a may be provided at the lower elastic protrusion 1220ab. The plurality of interference portions 1221a of the lower elastic protrusion 1220ab may be arranged parallel to each other in the up-down direction. However, the present disclosure is not limited thereto, and a single interference portion 1221a may be provided also at the lower elastic protrusion 1220ab. Alternatively, a plurality of interference portions 1221a may be provided also at the upper elastic protrusion 1220aa. The number of interference portions 1221a provided at the upper elastic protrusion 1220aa and the number of interference portions 1221a provided at the lower elastic protrusion 1220ab may be equal to each other or different from each other.

For example, one end of the interference portion 1221a of the upper elastic protrusion 1220aa in the first direction X may be provided to include the shape of a curved surface. The contact surface 1221as1 and the corner surface 1221as2 may be formed to be connected to each other and constitute a single curved surface shape together.

For example, the contact surface 1221as1 may extend in the second direction Y, and the corner surface 1221as2 may extend to be inclined relative to the direction in which the contact surface 1221as1 extends (refer to the lower elastic protrusion 1220ab of FIG. 12). The contact surface 1221as1 may longitudinally extend in the second direction Y. The radius of curvature of the contact surface 1221as1 and the radius of curvature of the corner surface 1221as2 may be provided to be different from each other, and more specifically, the radius of curvature of the contact surface 1221as1 may be provided to be greater than the radius of curvature of the corner surface 1221as2.

However, the present disclosure is not limited thereto, and the shapes of the upper elastic protrusion 1220aa and the lower elastic protrusion 1220ab may be different from those illustrated in FIG. 12 and so on. For example, the upper elastic protrusion 1220aa and the lower elastic protrusion 1220ab may be formed to have shapes that correspond to each other. For example, an elastic protrusion having the shape of the lower elastic protrusion 1220ab illustrated in FIG. 12 may be disposed at an upper portion, and an elastic protrusion having the shape of the upper elastic protrusion 1220aa illustrated in FIG. 12 may be disposed at a lower portion.

Unlike in FIG. 12 and so on, only a single elastic protrusion 1220a may be provided on the ice maker case wall 1210a, or three or more elastic protrusions 1220a may be provided on the ice maker case wall 1210a.

The elastic protrusion 1220a may be integrally formed with the ice maker case wall 1210a. Further, the overall configuration of the ice maker case 1200 may be integrally formed by injection molding. However, the present disclosure is not limited thereto, and the elastic protrusion 1220a may be separately formed from the ice maker case wall 1210a and then coupled thereto.

Although the ice maker case 1200 configured to support the ice making units 1300 and 1400 and the ice maker cover 1100 configured to cover the ice maker case 1200 in the ice maker 1000 of the refrigerator 1 according to one or more embodiments of the present disclosure have been separately described above, the spirit of the present disclosure is not limited thereto.

For example, the ice maker case 1200 and the ice maker cover 1100 may be integrally formed, and here, as integrated configurations supporting the ice making units 1300 and 1400, the ice maker case 1200 and the ice maker cover 1100 may be referred to as ice maker cases 1100 and 1200. As described above, the ice maker cases 1100 and 1200 may include configurations such as the ice maker case walls 1210a and 1210b and the elastic protrusions 1220a and 1220b.
